Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-7, 14-20, and 24 are rejected under 35 U.S.C. 103 as being unpatentable over Yi et al. (Patent No: US 2023/0023041 A1), hereinafter, Yi, in view of YIU et al. (Patent No: US 2022/0046487 A1), hereinafter, YIU, and further in view of HWANG et al. (Patent No: US 2019/0052377 A1), hereinafter, HWANG.
Regarding Claim 1, Yi teaches,
A method of wireless communication at a user equipment (UE), comprising: receiving a reference signal from a base station; -Paragraph [0226] ([0226] recites, “a wireless device may perform a radio link monitoring (RLM) measurements in an active BWP of a primary cell based on one or more reference signals such as SSB (synchronization signal and PBCH block) and/or CSI-RS. The wireless device may measure signal qualities of the one or more reference signals and compare the measured signal qualities with one or more signal quality thresholds configured by a base station. The base station may configure one or more SSBs as the reference signals for a case where an initial downlink BWP of the primary cell is the active BWP of the primary cell, and the initial downlink BWP comprises the one or more SSBs. “)
Although implicit, Yi does not explicitly mention,
in response to receiving the reference signal, determining that multiple groups of consecutive out-of-sync indications have occurred in response to the reference signal; and in response to determining that the multiple groups of consecutive out-of-sync indications have occurred, triggering a radio link monitoring (RLM) timer.
However, in an analogous invention, YIU teaches,
-Paragraph [0058]([0058] recites, “..The RLF reporting condition can be based on both cells having out-of-sync signals received at the same time in order to start the timer (i.e., multiple groups of consecutive out-of-sync indication), with the following timer configurations: Timer start—both the serving cell and the target cell received N out-of-sync signals; Timer stop—at least one cell receives an in-sync signal; Time expired—an RLF is declared.” It is inherent that consecutive groups of out-of-sync indications are determined in response to the reference signal)
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the “RADIO LINK MONITORING” proposed by Yi to include the concept of “ in response to receiving the reference signal, determining that multiple groups of consecutive out-of-sync indications have occurred in response to the reference signal; and in response to determining that the multiple groups of consecutive out-of-sync indications have occurred, triggering a radio link monitoring (RLM) timer.” of YIU. One of ordinary skill in the art would have been motivated to make this modification in order to improve RLF performance of the wireless communication network when using dual connectivity in the wireless communication network [0057]
Although implicit and readily understandable to an ordinary person with the skill in the art, Yi and YIU combination do not explicitly mention,
Out-of-sync calculation in response to receiving the reference signal
However, in an analogous invention, HWANG teaches,
Out-of-sync calculation in response to receiving the reference signal -Paragraph [0186] ([0186] recites, “Since the various RSs can be used as the RLM-RS as described in subsection (1), different RLF parameter sets may be set for different BWPs. When a new active BWP is scheduled, the base station may transmit the terminal at least some of the following values as RLF parameters: the IS threshold (RSRP, RSRQ, RSSI, SINR, or BLER in consideration of hypothetical PDCCH transmission) to generate an IS indication if the reception power is higher than the IS threshold, the OOS threshold (RSRP, RSRQ, RSSI, SINR, or BLER in consideration of hypothetical PDCCH transmission) to generate an OOS indication if the reception power is lower than the OOS threshold, the time window for IS and OOS measurement, the interval between IS or OOS indications sent to the higher layer, the number of RSs or beams that should be higher than the IS threshold for IS indication generation, the number of RSs or beams that should be lower than the OOS threshold for OOS indication generation, the RLF timer value, the number of consecutive OOS indications to start the RLF timer, and the number of consecutive IS indications to stop the running RLF timer.”)
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the “RADIO LINK MONITORING” proposed by Yi to include the concept of “Out-of-sync calculation in response to receiving the reference signal” of HWANG. One of ordinary skill in the art would have been motivated to make this modification in order to effectively calculate out-of-sync from reference signal.
Regarding Claim 2, Yi, YIU and HWANG teach the limitations of Claim 1.
Yi further teaches,
The method of claim 1, wherein the reference signal is a synchronization signal block (SSB). -Paragraph [0226] ([0226] recites, “ a wireless device may perform a radio link monitoring (RLM) measurements in an active BWP of a primary cell based on one or more reference signals such as SSB (synchronization signal and PBCH block) and/or CSI-RS.”)
Regarding Claim 3, Yi, YIU and HWANG teach the limitations of Claim 1.
Yi further teaches,
The method of claim 1, wherein the reference signal is a channel state information reference signal (CSI-RS). -Paragraph [0226] ([0226] recites, “ a wireless device may perform a radio link monitoring (RLM) measurements in an active BWP of a primary cell based on one or more reference signals such as SSB (synchronization signal and PBCH block) and/or CSI-RS.”)
Regarding Claim 4, Yi, YIU and HWANG teach the limitations of Claim 1.
Yi further teaches,
The method of claim 1, wherein the consecutive out-of-sync indications are determined based on a threshold (Qout) corresponding to an out-of-sync block error rate. -Paragraph [0242] ([0242] recites, “In an example, the wireless device may indicate, in radio frames, where the radio link quality is measured/assessed, an out-of-sync to the wireless device's higher layer (e.g., RRC layer), wherein the link qualities of the all one or more RLM-RSs are worse than the second threshold (e.g., Qout).”
Regarding Claim 5, Yi, YIU and HWANG teach the limitations of Claim 1.
Yi further teaches,
The method of claim 1, further comprising: determining one or more in-sync indications before expiration of the RLM timer based on a threshold (Qin) corresponding to an in-sync block error rate. -Fig. 19; Paragraph [0242, 0246] ([0242] recites, “The wireless device may indicate, in the radio frames, where the radio link quality is measured/assessed, an in-sync to the wireless device's higher layer (e.g., RRC layer), wherein link qualities of at least one RLM-RS from the one or more RLM-RSs are better than the first threshold (e.g., Qin).” [0246] recites,” FIG. 19 illustrates an example of cancelling the first timer based on in-sync event(s). In response to the starting of the first timer (e.g., T310), the wireless device may set the in-sync counter (e.g., N311 counter) as zero. The wireless device may increment the in-sync counter in response to receiving an in-sync event from the lower layer. When the in-sync counter reaches a second counter (e.g., N311) or a second threshold, the wireless device may stop the first timer. For example, the in-sync counter becomes N311 at a time of 4T in FIG. 19. The wireless device stops T310 timer (the first timer) so that the wireless device may not declare a RLF.”)
Regarding Claim 6, Yi, YIU and HWANG teach the limitations of Claim 1.
Yi further teaches,
The method of claim 1, wherein each of the multiple groups of consecutive out-of-sync indications correspond to a different cell. -Fig.30; Paragraph [0356][0316-0317] ( Fig. 30 shows RLM measurements on two cells and RLF determination based on consecutive out-of-sync indications and Timers. [0356] recites, “….The wireless device may perform a first RLM based on the first RLM-RS and the second RLM-RS for the first cell. The wireless device may perform a second RLM based on the third RLM-RS and the fourth RLM-RS for the second cell. The wireless device may perform the first RLM and the second RLM independently….”[0316-0317] recites, “In an example, the first cell may be a primary cell of a cell group (e.g., PCell, PSCell) or a cell supporting a radio link monitoring (e.g., a PUCCH cell). In an example, the second cell may be a secondary cell of the cell group. Based on the out-of-sync events/measurements, the wireless device may determine/declare a radio link failure (RLF) for the first cell.”)
Regarding Claim 7, Yi, YIU and HWANG teach the limitations of Claim 1.
Yi further teaches,
The method of claim 1, wherein each of the multiple groups of consecutive out-of-sync indications correspond to a different carrier. -Fig. 22, 23; Paragraph [0282-0284] (Fig. 22, 23 show cross-carrier and multi-carrier scheduling [0028-0029]. [0282] recites, “ FIG. 22 illustrates an example of a cell (Cell 1) configured with both self-carrier and cross-carrier scheduling. The base station configures cross-carrier scheduling for a first cell (Cell 0), wherein a scheduling cell is a second cell (Cell 1)….”)
Claims 14-20 are apparatus claims corresponding to the method claims 1-7. The Applicant’s attention is directed towards Claims 1-7 above which are rejected. Claims 14-20 are rejected under the same rational as Claims 1-7.
Yi further teaches,
An apparatus for wireless communication, comprising: a processor; memory coupled with the processor; and instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to: -Fig. 15 (Wireless device (1502), Processing System (1518), Memory (1524))
Regarding Claim 24, Yi, YIU and HWANG teach the limitations of Claim 14.
Yi further teaches,
The apparatus of claim 14, wherein the multiple groups of consecutive out-of-sync indications correspond to a same carrier. -Paragraph [0376][0286]([0376] recites, “…For example, the wireless device may start a first timer (e.g., T310) in response to triggering a number of consecutive out-of-sync events…” [0286] recites, “The wireless device may monitor/measure radio link qualities of one or more reference signals transmitted via the primary cell. The wireless device may be configured for self-carrier scheduling of the primary cell.” This implies group of consecutive out-of-sync events corresponds to same carrier)
Claims 21, 22 are rejected under 35 U.S.C. 103 as being unpatentable over Yi in view of YIU, HWANG and further in view of SHI ZHIHUA et al. (Patent No: CN 109644361A), hereinafter, SHI.
Regarding Claim 21, Yi, YIU and HWANG teach the limitations of Claim 14.
Although implicit, Yi does not explicitly mention,

However, in an analogous invention SHI teaches,
The apparatus of claim 14, wherein the multiple groups comprise more than two groups of consecutive out-of-sync indications, and wherein each of the more than two groups correspond to a different cell. -Paragraph [0030] ([0030] recites, “Optionally, if the measurement result of all target reference signals in the first QCL group is less than OOS BLER, the terminal device can continue to perform RLM measurement on the target reference signals in other unmeasured QCL groups. When the measurement results of the target reference signals in all QCL groups meet the second condition, the terminal device can report OOS to the network device.” As explained above, RLM measurement can continue on multiple QCL groups (can be greater than two or any number) if the target reference signal in the first QCL group is less that OOS BLER. Also, it is well understood by an ordinary person knowledgeable in the field of the art that different QCL groups corresponds to different cells.)
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the “RADIO LINK MONITORING” proposed by Yi to include the concept of “the multiple groups comprise more than two groups of consecutive out-of-sync indications, and wherein each of the more than two groups correspond to a different cell.” of SHI . One of ordinary skill in the art would have been motivated to make this modification in order to efficiently perform RLM measurement based on reference signals that satisfy the QCL relationships on multiple BWPs [0007].

[0224-0225] recites, “As shown in FIG. 4, if the measurement result includes the quantity of all the consecutive OOS states that are counted by the terminal device by performing RLM in the BWP #2, N1=Q1 and P1=0. In this case, the terminal device removes the Q OOS states, and re-counts, starting from 0, a quantity of consecutive OOS states. In a possible implementation, the counter may be set to zero, so that the terminal device re-counts, starting from 0 by using the counter, the quantity of OOS states that are reported by performing RLM in the BWP #1.)

In a second time period, the terminal device needs to switch from the BWP #A to a BWP #B, and when performing RLM in the BWP #B, the terminal device continues to perform RLM based on the measurement result #A.” [0016-0017] recites, “In a possible implementation, the removing, by the terminal device, a measurement result obtained by performing RLM in the second BWP includes: counting, by the terminal device starting from P1, a quantity of consecutive OOS states, where the measurement result includes the quantity N1 of at least some OOS states, P1=Q1−N1. Q1 is a quantity of consecutive OOS states that is counted by the terminal device by performing RLM in the second BWP, and N1 is less than or equal to Q1; “ It is easily understandable to an ordinary person with the skill in the art that for different BWPs the value of number of out-of-sync can be different depending on the configuration and design choice.)
