Regarding claim 1, BAI teaches a method by a user equipment (UE) in a cellular network (
Fig. 1, [0064] FIG. 1 illustrates an example of a wireless communications system 100 that supports beam management using channel state information prediction in accordance with aspects of the present disclosure. The wireless communications system 100 includes base stations 105, UEs 115, and a core network 130.
Fig. 2, wireless communications system 200 may include a base station 105-a and a UE 115-a, [0103] FIG. 2 illustrates an example of a wireless communications system 200 that supports beam management using channel state information prediction in accordance with aspects of the present disclosure. …. the wireless communications system 200 may include a base station 105-a and a UE 115-a ..….the wireless communications system 200 may support an improved beam management procedure….
[0059] A base station …. or giga-NodeB (….gNB)) and a user equipment (UE) may perform a beam management procedure such as a beam switch procedure or a beam failure recovery procedure. In an example beam switch procedure, a base station may configure one or more reference signals. A subset of the configured reference signals may be used by the UE to monitor downlink and uplink control channels or data channels, while another subset may be used to identify candidate beams (e.g., satisfying a threshold). For example, a UE may monitor a reference signal, for example, a channel state information reference signal (CSI-RS). The UE may measure a signal quality of the configured reference signals (e.g., based on the CSI-RS) and may transmit a report of the signal quality to the base station.
[0060] Based on the report, the base station may transmit a beam switch message to the UE on a physical downlink control channel (PDCCH), a medium access control (MAC) control element (CE), radio resource control (RRC) signaling, or a combination thereof. Upon receiving the beam switch message, the base station and the UE may establish communication over the newly indicated beam. Alternatively, in an example beam failure recovery procedure, the UE may identify a link issue (e.g., a metric of a communication beam may be below a threshold).
[0062] The techniques described herein may forecast a beam event using a learning algorithm, which may apply one or more parameters, such as a measured channel quality parameters or additional information (also referred to herein as side information), or a combination thereof. …. For example, a UE may transmit, to a base station, an indication of a value of a channel quality parameter of a wireless link including a beam pair between the UE and the base station, and transmit, to the base station, side information different from and in addition to the indication of the value of the channel quality information. The base station may receive the channel quality parameter and the side information from the UE, and determine a future value of the channel quality parameter. In response, the base station may determine resources (e.g., a beam switch) for the UE to use to communicate with the base station on the wireless link.
[0118] the mobility information of the UE 115-a may include a speed or a velocity of the UE 115-a within a coverage area of the base station 105-a.
[0164] the side information includes UE mobility information, or a Doppler spread, or an indication of past receive beam changes by the UE, or a combination thereof. In some cases, the side information includes a time stamp for the measuring of the value. In some cases, the side information further includes an indication of a duration for which the side information is valid.
See also Fig. 4, [0133] FIG. 4 illustrates an example of a proactive beam management scheme 400 that supports beam management using channel state information prediction in accordance with aspects of the present disclosure. The proactive beam management scheme 400 may implement aspects of the wireless communications systems 100 and 200, such as providing improvements in beam management procedures.….
[0134] The proactive beam management scheme 400 may include a prediction algorithm 405, which may be a deep learning algorithm ……. In some examples, the prediction algorithm 405 may be trained, and even after being trained the prediction algorithm 405 may continue learning based on actual deployment circumstances. In other examples, the prediction algorithm 405 may use one or more filters, for example, such as a Kalman filter, which may use a linear combination of past measurements (e.g., past channel quality measurements) to determine a future measurement (e.g., a future value of a channel quality parameter). ), comprising:
determining that a radio link failure (RLF) has previously occurred within a threshold distance from a current location of the UE (
[0104] … the base station 105-a and the UE 115-a may perform a connection procedure to re-establish a connection after a connection failure (e.g., a radio-link failure) with the base station 105-a ….
[0108] In some examples, a quality of the established communication link (e.g., a beam pair (e.g., the beam 205-a and/or the beam 210-a)) between the base station 105-a and the UE 115-a may vary over time, for example, due to mobility of the UE 115-a, or dynamic blockages (e.g., obstructions (e.g., buildings)). By way of example, the base station 105-a may transmit a reference signal periodically or aperiodically to the UE 115-a, so that the UE 115-a may perform channel measurements to monitor a value of a channel quality parameter of the communication link between the base station 105-a and the UE 115-a. For example, the UE 115-a may determine that an RSRP of an active beam (e.g., the beam 210-a) has fallen below a threshold (e.g., below an RSRP threshold).
[0110] For example, the base station 105-a and the UE 115-a may determine (e.g., predict, forecast, estimate) a value of a channel quality parameter associated with an active beam of a communication link. …… may forecast a beam event using a learning algorithm, which may take as input one or more parameters, such as a value of a channel quality parameter or side information, or a combination thereof.
(Based on current CQI forecast an RLF event based on past event learnt)
[0118] the mobility information of the UE 115-a may include a speed or a velocity of the UE 115-a within a coverage area of the base station 105-a.
(Coverage area == Threshold distance)
[0164] the side information includes UE mobility information, or a Doppler spread, or an indication of past receive beam changes by the UE, or a combination thereof
(Construed that UE based on its current location withing coverage area of a base station determines a past RLF event based on past measurement report including past channel quality and side information including mobility and beam change event within the same coverage area of base station 105 or within a threshold distance from a current location of the UE the location having obstructions));
responsive to determining that the RLF has previously occurred, determining an expected beam to be encountered by the UE and associated with the RLF (
[0110] the base station 105-a and the UE 115-a may support …. a proactive approach to determine (e.g., predict, forecast, estimate) a beam event, such as a beam switch event or a beam failure event, prior to an actual beam event incidence. For example, the base station 105-a and the UE 115-a may determine (e.g., predict, forecast, estimate) a value of a channel quality parameter associated with an active beam of a communication link. …… may forecast a beam event using a learning algorithm, which may take as input one or more parameters, such as a value of a channel quality parameter or side information, or a combination thereof.
[0111] In some examples, the base station 105-a (and the UE 115-a) may select and use a learning algorithm (also referred to herein as a prediction algorithm) from a set of learning algorithms to determine a future value of a channel quality parameter of a communication link (e.g., of an active beam pair) between the base station 105-a and the UE 115-a.
[0112] In other examples, the learning algorithm may use one or more filters, for example, such as a Kalman filter, which may use a linear combination of past measurements (e.g., a past value of a channel quality parameter) to determine a future measurement (e.g., a future value of the channel quality parameter).
[0114] Additionally or alternatively to performing channel measurements for active beam pairs (e.g., the beam 205-a of the base station 105-a or the beam 210-a of the UE 115-a), the channel measurements may be performed for other beams that may be referred to as candidate active beams (e.g., the beams 205-b through 205-d of the base station 105-a, and the beams 210-b through 210-d of the UE 115-a). A candidate active beam may be a fallback beam in case an active beam has fallen below a threshold (e.g., RSRP threshold, RSRQ threshold).
(Construed that a candidate active beam may be a fallback beam indicates an expected beam which is associated with active beam which previously failed/to be fail at the location or the previously reported nearby location in the mobility route of the UE));
generating a first beam measurement report for the expected beam, the first beam measurement report including an adjusted power measurement for the expected beam (
[0113] the base station 105-a may transmit a CSI-RS or a DMRS, and the like on the beam 205-a. The UE 115-a may perform a channel measurement based on the one or more downlink reference signals. For example, the UE 115-a may measure an RSRP, an RSRQ, an SNR, or an SINR, or the like, and may report the channel measurements to the base station 105-a.
[0114] Additionally …. to performing channel measurements for active beam pairs (e.g., the beam 205-a of the base station 105-a or the beam 210-a of the UE 115-a), the channel measurements may be performed for other beams that may be referred to as candidate active beams (e.g., the beams 205-b through 205-d of the base station 105-a, and the beams 210-b through 210-d of the UE 115-a). A candidate active beam may be a fallback beam in case an active beam has fallen below a threshold (e.g., RSRP threshold, RSRQ threshold). The base station 105-a or the UE 115-a, or both, may switch to a candidate active beam, which in this case may become the active beam. ….. the base station 105-a and the UE 115-a may select a candidate active beam that may remain above a threshold (e.g., RSRP threshold, RSRQ threshold) for at least a duration (e.g., one or more slots) after a beam switch event.….. The channel measurements associated with the candidate active beams may also be reported together or separately with the active beam channel measurements.
(UE report an acceptable reception powers of candidate beams which are adjusted reception power measurements based on a threshold )
Fig. 6, Message 630,
[0144] At 610, the base station 105-c may transmit control information to the UE 115-c. The control information may include an indication of the determined future value of the channel quality parameter.
[0145] At 620, the base station 105-c may transmit one or more reference signals (e.g., CSI-RS, TRS) to the UE 115-c. At 625, the UE 115-c may measure the one or more reference signals and determine an actual value of the channel quality parameter. At 630, the UE 115-c may transmit an error report message, for example, including an error report. In some examples, the error reporting may be trigger-based. For example, the UE 115-c may compare the indicated future value to the actual value of the channel quality parameter and transmit the error report based in part on the comparison.); and
transmitting the first beam measurement report to the cellular network (
See [0114] The channel measurements associated with the candidate active beams may also be reported together or separately with the active beam channel measurements).
BAI does not explicitly disclose generating a first beam measurement report for the expected beam, the first beam measurement report including an adjusted power measurement obtained by adjusting a measured power value for the expected beam.
In an analogous art, XU teaches generating a first beam measurement report for the expected beam, the first beam measurement report including an adjusted power measurement obtained by adjusting a measured power value for the expected beam (
Fig. 6, Box 602 – Box 606, [0062] At 602, the UE may perform beam measurements for a plurality of beams, such as described in connection with FIGs. 4 and 5. The beam measurements may include measurement of at least one of RSRP, CQI, PMI, CRI and RI of the plurality of beams, such as described in connection with, such as described in connection with Table 1 and FIGs. 4 and 5.
[0063] t 604, the UE may determine that a candidate beam among the plurality of beams is better than a current serving beam of the UE, such as described in connection with Table 1 and FIGs. 4 and 5. The plurality of beams may comprise both the candidate beam and the current serving beam.
[0064] At 606, the UE may modify at least one beam measurement for one or more of the candidate beam and the current serving beam, such as described in connection with Table 1 and FIGs. 4 and 5. In one example, modifying the at least one beam measurement for one or more of the candidate beam and the current serving beam may include increasing a value of a measurement for the candidate beam, such as described in connection with Table 1 and FIG. 5.
[0065] At 608, …. the UE may report the at least one modified beam measurement to the base station, such as described in connection with Table 1 and FIGs. 4 and 5.)
Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to take the technique of reporting modified beam measurement values of XU to the system of proactive beam management scheme based on beam reference signal RSRP of BAI in order to take the advantage of method for measurement reporting so the base station may observe a larger gap in the beam quality between the current serving beam and a potential candidate beam, and the base station may then trigger the beam switching for the UE to avoid possible radio link failure [XU: [0001, 0049, 0050]).
Regarding claim 15, BAI teaches a non-transitory computer-readable medium storing executable instructions configured to manipulate a processor of a user equipment to implement the method (
Fig. 1, [0064] FIG. 1 illustrates an example of a wireless communications system 100 that supports beam management using channel state information prediction in accordance with aspects of the present disclosure.

The device 1005 may be an example of or include …. a UE 115 as described herein. The device 1005 may include components for bi-directional voice and data communications including components for transmitting and receiving communications, including a communications manager 1010, an I/O controller 1015, a transceiver 1020, an antenna 1025, memory 1030, and a processor 1040.
[0173] The memory 1030 may include RAM and ROM. The memory 1030 may store computer-readable, computer-executable code 1035 including instructions that, when executed, cause the processor to perform various functions described herein.).
Further claim 15 is interpreted and rejected for the same reason as set forth for claim 1.
Regarding claim 16, BAI teaches a user equipment (UE) (
Fig. 1, Fig. 1, [0064] FIG. 1 illustrates an example of a wireless communications system 100 that supports beam management using channel state information prediction in accordance with aspects of the present disclosure. The wireless communications system 100 includes base stations 105, UEs 115, and a core network 130.) comprising:

The device 1005 may include components for bi-directional voice and data communications including components for transmitting and receiving communications, including a communications manager 1010, an I/O controller 1015, a transceiver 1020, an antenna 1025, memory 1030, and a processor 1040.
[0173] The memory 1030 may include RAM and ROM. The memory 1030 may store computer-readable, computer-executable code 1035 including instructions that, when executed, cause the processor to perform various functions described herein.).
Further claim 16 is interpreted mutatis mutandis of claim 1 and rejected for the same reason as set forth for claim 1.
Regarding claim 2, BAI, in view of XU, teaches the method of claim 1, wherein the determining of the expected beam is further in response to determining that a current route of the UE substantially corresponds to route information recorded by the UE when the RLF previously occurred (
[0110] the base station 105-a and the UE 115-a may support …. a proactive approach to determine (e.g., predict, forecast, estimate) a beam event, such as a beam switch event or a beam failure event, prior to an actual beam event incidence. For example, the base station 105-a and the UE 115-a may determine (e.g., predict, forecast, estimate) a value of a channel quality parameter associated with an active beam of a communication link. …… may forecast a beam event using a learning algorithm, which may take as input one or more parameters, such as a value of a channel quality parameter or side information, or a combination thereof.
[0112] In other examples, the learning algorithm may use one or more filters, for example, such as a Kalman filter, which may use a linear combination of past measurements (e.g., a past value of a channel quality parameter) to determine a future measurement (e.g., a future value of the channel quality parameter).
[0114] Additionally …. to performing channel measurements for active beam pairs (e.g., the beam 205-a of the base station 105-a or the beam 210-a of the UE 115-a), the channel measurements may be performed for other beams that may be referred to as candidate active beams (e.g., the beams 205-b through 205-d of the base station 105-a, and the beams 210-b through 210-d of the UE 115-a). A candidate active beam may be a fallback beam in case an active beam has fallen below a threshold (e.g., RSRP threshold, RSRQ threshold). The base station 105-a or the UE 115-a, or both, may switch to a candidate active beam, which in this case may become the active beam. ….. The channel measurements associated with the candidate active beams may also be reported together or separately with the active beam channel measurements.
[0118] the mobility information of the UE 115-a may include a speed or a velocity of the UE 115-a within a coverage area of the base station 105-a.
[0164] the side information includes UE mobility information, or a Doppler spread, or an indication of past receive beam changes by the UE, or a combination thereof.
(Construed that determining of the selected candidate active beams or expected beam is further in response to determining that a current route location of the UE is in the same coverage are of base station 105 substantially corresponds to route location coverage area of base station 105 previously recorded and reported by the UE where or when beam switch event due to the beam failure or RLF previously occurred)).
Regarding claim 3, BAI, in view of XU, teaches the method of claim 1, wherein the first beam measurement report is generated and transmitted to the cellular network during a time interval that is prior to a time interval during which a beam measurement report for the expected beam is generated and transmitted when the RLF has not occurred (
See [0110, 0112, 0114, 0118, 0164] past reports including measurements and side information including mobility information which include coverage information of base station 105, beam failures and beam switch before next beam measurement report with predicted beam failures and beam switch).
Regarding claim 4, BAI, in view of XU, teaches the method of claim 1.
BAI does not explicitly disclose wherein generating the first beam measurement report comprises one of:
increasing an original power measurement by a predefined incremental value to obtain the adjusted power measurement
increasing the original power measurement by a predefined maximum value to obtain the adjusted power measurement; or
increasing the original power measurement by a fixed value to obtain the adjusted power measurement.
XU teaches wherein generating the first beam measurement report comprises one of:
increasing an original power measurement by a predefined incremental value to obtain the adjusted power measurement (
[0050] if a candidate CSI-RS beam has an RSRP better than the current serving CSI-RS beam, e.g., by at least an offset amount, the UE may give a further plus to the RSRP of the candidate beam when reporting the RSRP to the base station, such as by adding a pre-defined value or variable to the RSRP);
increasing the original power measurement by a predefined maximum value to obtain the adjusted power measurement; or
increasing the original power measurement by a fixed value to obtain the adjusted power measurement (
See [0051], Table 1, [0053] Candidate beam increased by an extra 2 dB).
Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to take the technique of reporting modified beam measurement values of XU to the system of proactive beam management scheme based on beam reference signal RSRP of BAI in order to take the advantage of method for measurement reporting so the base station may observe a larger gap in the beam quality between the current serving beam and a potential candidate beam, and the base station may then trigger the beam switching for the UE to avoid possible radio link failure [XU: [0001, 0049, 0050]).
Regarding claim 5, BAI, in view of XU, teaches the method of claim 1.
BAI does not explicitly disclose wherein generating the first beam measurement report comprises:
adjusting the adjusted power measurement for the expected beam to indicate that the expected beam is more optimal than neighboring beams.
XU teaches wherein generating the first beam measurement report comprises:
adjusting the adjusted power measurement for the expected beam to indicate that the expected beam is more optimal than neighboring beams (
[0047] To optimize the network transmission and/or to achieve stable higher data rate, the beam management procedure may configure the UE 404 to stay at the best CSI-RS beam (s) of the base station 402. Thus, after the base station 402 receives the CSI-RS beam measurement 410 from the UE 404, the base station 402 may have the UE 404 stay on the current beam (s) , or may request that the UE 404 switches one or more beam (e.g., BPL) to another beam (s) with better beam measurements.
[0053] the UE may report the adjusted measurement values to the base station. Thus, the base station may observe a larger offset between the candidate beam and the current serving beam (e.g., the offset may be 7 dB instead of 3 dB), and the base station may be more likely to initiate the beam Switching).
Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to take the technique of reporting modified beam measurement values of XU to the system of proactive beam management scheme based on beam reference signal RSRP of BAI in order to take the advantage of method for measurement reporting so the base station may observe a larger gap in the beam quality between the current serving beam and a potential candidate beam, and the base station may then trigger the beam switching for the UE to avoid possible radio link failure [XU: [0001, 0049, 0050]).
Regarding claim 6, BAI, in view of XU, teaches the method of claim 1, further comprising:
responsive to transmitting the first beam measurement report to the cellular network, determining a base station (106) has indicated a beam switch to the expected beam; and
changing a receive beam to the expected beam (
See [0114] cited for claim 1).
Regarding claim 17, the claim is interpreted and rejected for the same reason as set forth for claim 2.
Regarding claim 18, the claim is interpreted and rejected for the same reason as set forth for claim 3.
Regarding claim 19, the claim is interpreted and rejected for the same reason as set forth for claim 4.
Regarding claim 20, the claim is interpreted and rejected for the same reason as set forth for claim 6.
Claims 7-13 and 21-24 are rejected under AIA 35 U.S.C. 103 as being unpatentable over Bai et al. US 20200259545 A1, of IDS, hereinafter ‘BAI’) in view of Xu et al. (WO 2021232231 A1, hereinafter ‘XU’) and with further in view of Huawei et al. (R4-1809048 “Discussion on Beam Measurement and Reporting for Beam Management”, of IDS, hereinafter ‘HUAWEI’).
Regarding claim 7, BAI, in view of XU, teaches the method of claim 1.
BAI and XU do not explicitly disclose responsive to determining that a base station has not indicated a beam switch, checking an accuracy of the first beam measurement report.
In an analogous art, HUAWEI teaches responsive to determining that a base station has not indicated a beam switch, checking an accuracy of the first beam measurement report (
Page 2 Paragraphs 4-5:
For a beam RS resource, the reliability of reported Ll-RSRP shall be guaranteed at least when beam failure is not triggered. Therefore, the side condition shall be defined as a relative good SINR level. The side condition of reported Ll-RSRP accuracy requirements can be defined as SINR=0dB.
For mobility measurements, 5 measurement samples are assumed for SS-RSRP, and the absolute and relative SS-RSRP measurement accuracy are defined as ±4.5dB and ±3dB. If the same measurement accuracy requirements are reused for reported L1-RSRP, then it could be assumed that one measurement period includes 3 measurement samples for SSB based L1-RSRP and 5 measurement samples for CSI-RS based L1-RSRP.
See also Proposal 2 and Proposal 3).
Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to take the technique of reporting SS-RSRP based on multiple sample of HUAWEI to the system of proactive beam management scheme based on beam reference signal RSRP of BAI and XU in order to take the advantage of method for guaranteeing reliability of reported L1-RSRP or SS-RSRP for the beam management [HUAWEI: Page 1 Paragraph 5, Page 2 Paragraph 4).

If the same measurement accuracy requirements are reused for reported L1-RSRP, then it could be assumed that one measurement period includes 3 measurement samples for SSB based L1-RSRP and 5 measurement samples for CSI-RS based L1-RSRP.).

(In the above measurement period is an obvious indication for installing a timer and collecting measurement samples before expiration of the timer period)).
Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to take the technique of reporting SS-RSRP based on multiple sample of HUAWEI to the system of proactive beam management scheme based on beam reference signal RSRP of BAI and XU in order to take the advantage of method for guaranteeing reliability of reported L1-RSRP or SS-RSRP for the beam management [HUAWEI: Page 1 Paragraph 5, Page 2 Paragraph 4).
Regarding claim 11, BAI, in view of XU and HUAWEI, teaches the method of any one of claim 7.
BAI and XU do not explicitly disclose responsive to the accuracy of the first beam measurement report satisfying one or more conditions, generating a second beam measurement report for the expected beam, the second beam measurement report including a further adjusted power measurement for the expected beam; and
transmitting the second beam measurement report to the cellular network.
HUAWEI teaches responsive to the accuracy of the first beam measurement report satisfying one or more conditions, generating a second beam measurement report for the expected beam, the second beam measurement report including a further adjusted power measurement for the expected beam, and transmitting the second beam measurement report to the cellular network (
Page 1, Paragraph 5:
For beam management, UE shall perform L1-RSRP measurement on the configured CSI-RS resources or SS/PBCH Block resources and report measurement results to gNB. If the number of configured RS resources equals to one, then the value of measured L1-RSRP will be reported. If the number of configured RS resources is larger than one, then both the value of largest measured L1-RSRP and the values of differential L1-RSRP for each configured RS resource will be reported.
Page 2 Paragraph 1:
The reported results of L1-RSRP can be utilized for Tx/Rx beam selection. In order to guarantee the reliability of reported L1-RSRP, the measurement period of reported L1-RSRP need to be defined. As we discussed on L1-RSRP measurement for candidate beam detection, the requirements on L1-RSRP measurement period are related to the expected measurement accuracy and the corresponding side condition.).

Regarding claim 12, BAI, in view of XU and HUAWEI, teaches the method of any one of claim 7.
BAI and XU do not explicitly disclose responsive to the accuracy of the first beam measurement report failing to satisfy one or more conditions, generating a second beam measurement report for the expected beam comprising an original power measurement for the expected beam, and transmitting the second beam measurement report to the cellular network.
HUAWEI teaches responsive to the accuracy of the first beam measurement report failing to satisfy one or more conditions, generating a second beam measurement report for the expected beam comprising an original power measurement for the expected beam, and transmitting the second beam measurement report to the cellular network (

… if the higher layer parameter nrofR-eportedRS is configured to be larger than one, or if the higher layer parameter groupBasedBeamReporting is configured as 'enabled', the UE shall use differential LI -RSRP based reporting, where the largest measured value of LI -RSRP is quantized to a 7-bit value in the range [-140, -44] dBm with 1 dB step size, and the differential LI-RSRP is quantized to a 4-bit value. The differential LI-RSRP value is computed with 2 dB step size with a reference to the largest measured LI -RSRP value which is part of the same LI -RSRP reporting instance. The mapping between the reported LI -RSRP value and the measured quantity is described in [ 11, TS 38.133 ].

As we discussed on L1-RSRP measurement for candidate beam detection, the requirements on L1-RSRP measurement period are related to the expected measurement accuracy and the corresponding side condition.
For a beam RS resource, the reliability of reported Ll-RSRP shall be guaranteed at least when beam failure is not triggered. Therefore, the side condition shall be defined as a relative good SINR level. The side condition of reported Ll-RSRP accuracy requirements can be defined as SINR=0dB.
For mobility measurements, 5 measurement samples are assumed for SS-RSRP, and the absolute and relative SS-RSRP measurement accuracy are defined as ±4.5dB and ±3dB. If the same measurement accuracy requirements are reused for reported L1-RSRP, then it could be assumed that one measurement period includes 3 measurement samples for SSB based L1-RSRP and 5 measurement samples for CSI-RS based L1-RSRP.).
