In some examples, the first PC mode of the UE 115-b may correspond to a higher transmission power level compared to a second PC mode of the UE 115-b (e.g., PC3), [0092], At 325, the UE 115-b may identify an uplink BLER associated with the second PC mode. In some examples, the UE 115-b may identify the BLER based on transmitting the set of uplink signals using the second PC mode, at 320. In some examples, the UE 115-b may identify that the UL BLER associated with the second PC mode satisfies a threshold (e.g., exceeds a configured BLER threshold).

the second frequency band being different from the first frequency band ([0082], the UE 115-a may be configured to prioritize transmitting uplink messages based on the type of carrier an uplink grant is associated with. For example, the uplink grant scheduling message 215 may include a first uplink grant that indicates a first resource allocation on a primary component carrier (PCC) and second uplink grant that indicates a second resource allocation on a secondary component carrier (SCC). As such, the UE 115-a may be configured to prioritize transmitting a first uplink message scheduled by the first uplink grant based on the first uplink grant being associated with a PCC, when determining which one or more grants to prune for complying with the advertised duty cycle).

As an entry point, the device with multiple Tx chains that are active is in RRC-connected mode with the network. The device is operating in the UL MIMO mode with dual data layer uplink. The present disclosure provides a response with actions.

The network responds with a downgrade from PC 1.5 to PC 2 until above conditions improve, [0071], the communication device reactivates any deactivated Tx chains when continuous TPC-UP bits are observed, the device is unable to decode TPC bits in DL, device exits single data uplink layer mode and enters dual layer UL MIMO mode).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to incorporate the dual MIMO implementation switching between frequency bands, as taught in Chisu, in the system of Kumar, in order to conserve battery power and ensure the device remains connected, while optimize resource usage when power levels are high.
Regarding Claim 10, Kumar, as modified by Chisu, teaches the method of claim 9, Kumar further teaches determining, via processing circuitry of the base station, the power class and the plurality of frequency bands based on the first indication of the transmission capabilities of the user equipment ([0164-0165], Fig. 11, At 1105, the method may include transmitting, to a network entity, an advertisement message indicating an uplink transmission duty cycle associated with a first power class mode of the UE, the first power class mode of the UE corresponding to a higher transmission power level than a second power class mode of the UE, At 1110, the method may include receiving, from the network entity, a set of multiple uplink grants associated with a time interval, a quantity of transmission resources scheduled by the set of multiple uplink grants during the time interval exceeding the uplink transmission duty cycle associated with the first power class mode).
Regarding Claim 11, Kumar, as modified by Chisu, teaches the method of claim 10, Kumar further teaches wherein the user equipment is configured to transmit third user data using the first pair of transmitters using a first power class 1.5 configuration based on the second indication, and transmit fourth user data using the second pair of transmitters using a second power class 1.5 configuration based on the second indication ([0088], At 305, the UE 115-b may transmit to the network entity 105-b, an advertisement message indicating an uplink transmission duty cycle associated with a first PC mode of the UE 115-b (e.g., PC2 or PC1.5). In some examples, the first PC mode of the UE 115-b may correspond to a higher transmission power level compared to a second PC mode of the UE 115-b (e.g., PC3), [0092], At 325, the UE 115-b may identify an uplink BLER associated with the second PC mode. In some examples, the UE 115-b may identify the BLER based on transmitting the set of uplink signals using the second PC mode, at 320. In some examples, the UE 115-b may identify that the UL BLER associated with the second PC mode satisfies a threshold (e.g., exceeds a configured BLER threshold). In some examples, the network entity 105-b may transmit to the UE 115-b, a control signal indicating the BLER threshold, [0094], At 335, the UE 115-b may transition back from the second PC mode to the first PC mode. In some examples, the UE 115-b may determine to transition based on the distance satisfying the distance threshold, the BLER satisfying the BLER threshold, or a combination thereof).
Regarding Claim 12, Kumar, as modified by Chisu, teaches the method of claim 11, Kumar further teaches receiving, via the receiver, the first user data, the second user data, the third user data, and the fourth user data ([0065], network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices).
Regarding Claim 13, Kumar teaches a user equipment, comprising: at least one antenna; at least one transmitter respectively coupled to the at least one antenna ([0064], a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming); and processing circuitry coupled to the at least one transmitter ([0198-0199]) and configured to
operate the at least one transmitter in a multi-in multi-out (MIMO) configuration ([0065], network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices);
transmit first data via a first antenna of the at least one antenna on a first frequency band, transmit second data via a second antenna of the at least one antenna on the first frequency band ([0084], the UE 115-a may support MIMO transmissions. For example, the UE 115-a may include an antenna array 220, which may include one or more antenna elements 225. In some examples, each antenna element 225 may be configured to communicate data concurrently on respective transmission chains 240, where each transmission chain 240 may be associated with respective analog and digital components of the UE 115-a used for generating and communicating data with the network entity 105-a. In some cases, the UE 115-a may be configured with an antenna switching scheme 235, in which a first stream of data is switched from communication on a first antenna element 225 to communication on a second antenna element 225. For example, TDD stand-alone (SA) bands may support and advertise configuration for sounding reference signal (SRS) switching (e.g., for a two transmitter/four receiver (2T4R) antenna configuration)),
transmit third data via a third antenna of the at least one antenna on a second frequency band, and transmit fourth data via a fourth antenna of the at least one antenna on the second frequency band ([0085], each transmission chain 240 may have a respective advertised uplink duty cycle (e.g., indicated in the uplink duty cycle indication 205). As such, if the duty cycle associated with the uplink grant scheduling message 215 exceeds the advertised duty cycle for a first transmission chain 240, the UE 115-a may switch to a second transmission chain 240 and continue uplink transmissions at PC2 or PC1.5. For example, as illustrated in FIG. 2, the UE 115-a may perform a first portion of the uplink message transmission 230 using transmission chain 240-a, where the UE 115-a may transmit a first portion of PUSCH transmissions 245 associated with a first subset of uplink grants from the set of uplink grants scheduled at the UE 115-a. In some examples, the UE 115-a may concurrently transmit SRS transmissions 250 on transmission chain 240-b. Based on the PUSCH transmissions 245 occurring more frequently than the SRS transmissions 250, the duty cycle associated with transmission chain 240-a may be greater than the duty cycle associated with transmission chain 240-b. As such, during the uplink message transmission 230, the UE 115-a may perform a chain switch 255 in which the remaining portion of PUSCH transmission 245 associated with the remaining portion of uplink grants may be transmitted via transmission chain 240-b. That is, once the duty cycle for a first transmission chain exceeds the advertised uplink duty cycle of the first transmission chain 240, the UE 115-a may switch transmission to a second transmission chain 240 that is configured for non-SRS transmissions).
Kumar fails to teach the following, which in the same field of endeavor, Chisu teaches operate the at least one transmitter in a double multi-in multi-out (MIMO) configuration based on operational characteristics of the user equipment being above a threshold ([0064], Aspects of the present disclosure include a second part that addresses UL MIMO modes in device-controlled Tx chain configuration for high power modes. As an entry point, the device with multiple Tx chains that are active is in RRC-connected mode with the network. The device is operating in the UL MIMO mode with dual data layer uplink. The present disclosure provides a response with actions. The device deactivates (i.e., disables or places in LPM) lowest performing Tx chain(s) when: (i) battery level is low; (ii) no critical application is using the connection; or (iii) device is in a highly congested or faded area where there is no MIMO benefit due to radio frequency (RF) channel or backhaul conditions. RF congestion may be inferred based on monitoring for pilot pollution (i.e., strong total channel power but weak recovered energy). Backhaul congestion may be inferred based on monitoring IP packet segmentation levels relative to MTU. In one or more embodiments, the device may additionally temporarily signal to network in UE capability UL SISO support.

For example, the uplink grant scheduling message 215 may include a first uplink grant that indicates a first resource allocation on a primary component carrier (PCC) and second uplink grant that indicates a second resource allocation on a secondary component carrier (SCC). As such, the UE 115-a may be configured to prioritize transmitting a first uplink message scheduled by the first uplink grant based on the first uplink grant being associated with a PCC, when determining which one or more grants to prune for complying with the advertised duty cycle).
Regarding Claim 15, Kumar, as modified by Chisu, teaches the user equipment of claim 13, Kumar further teaches wherein each of the at least one antenna uses two intra-band component carriers based on the operational characteristics being above an additional threshold ([0048], UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration).

Then method 400 returns to block 404. In response to determining that the TPC-UP rate is greater than the threshold “B” in decision block 408, method 400 includes enabling both first and second transmit chains (Tx1 and Tx2) (block 412)).

Regarding Claim 17, Kumar, as modified by Chisu, teaches the user equipment of claim 13, Kumar further teaches at least one receiver respectively coupled to the at least one antenna; and the processing circuitry coupled to the at least one receiver and configured to receive an indication of a power class supported by a base station ([0164-0165], Fig. 11, At 1105, the method may include transmitting, to a network entity, an advertisement message indicating an uplink transmission duty cycle associated with a first power class mode of the UE, the first power class mode of the UE corresponding to a higher transmission power level than a second power class mode of the UE, At 1110, the method may include receiving, from the network entity, a set of multiple uplink grants associated with a time interval, a quantity of transmission resources scheduled by the set of multiple uplink grants during the time interval exceeding the uplink transmission duty cycle associated with the first power class mode), operate the at least one transmitter in a power class 1.5 (PC1.5) configuration based on the indication, transmit fifth data via the first antenna and the second antenna on the first frequency band, and transmit sixth data via the third antenna and the fourth antenna on the second frequency band ([0084], the UE 115-a may support MIMO transmissions. For example, the UE 115-a may include an antenna array 220, which may include one or more antenna elements 225. In some examples, each antenna element 225 may be configured to communicate data concurrently on respective transmission chains 240, where each transmission chain 240 may be associated with respective analog and digital components of the UE 115-a used for generating and communicating data with the network entity 105-a. In some cases, the UE 115-a may be configured with an antenna switching scheme 235, in which a first stream of data is switched from communication on a first antenna element 225 to communication on a second antenna element 225. For example, TDD stand-alone (SA) bands may support and advertise configuration for sounding reference signal (SRS) switching (e.g., for a two transmitter/four receiver (2T4R) antenna configuration)).

As an entry point, the device with multiple Tx chains that are active is in RRC-connected mode with the network. The device is operating in the UL MIMO mode with dual data layer uplink. The present disclosure provides a response with actions. The device deactivates (i.e., disables or places in LPM) lowest performing Tx chain(s) when: (i) battery level is low; (ii) no critical application is using the connection; or (iii) device is in a highly congested or faded area where there is no MIMO benefit due to radio frequency (RF) channel or backhaul conditions. RF congestion may be inferred based on monitoring for pilot pollution (i.e., strong total channel power but weak recovered energy). Backhaul congestion may be inferred based on monitoring IP packet segmentation levels relative to MTU. In one or more embodiments, the device may additionally temporarily signal to network in UE capability UL SISO support. The network responds with a downgrade from PC 1.5 to PC 2 until above conditions improve, [0071], the communication device reactivates any deactivated Tx chains when continuous TPC-UP bits are observed, the device is unable to decode TPC bits in DL, device exits single data uplink layer mode and enters dual layer UL MIMO mode).

Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Kumar et al (US 2024/0205837), in view of Chisu et al (US 2024/0146367), and further in view of Kim et al (US 2021/0296758).

Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Kwok (US 2023/0370317) discloses the centralized uplink technology controller implements intelligence in the form of a decision tree. The decision tree first assesses capabilities and then evaluates the possible uplink technologies based on RF conditions. In some instances, a wireless device 510 may be incapable of supporting multiple technologies. For example, the wireless device 510 may not support 2×2 MIMO. In this instance, the centralized uplink technology controller of the access node 520 determines which waveform switching technology maximizes throughput for the wireless device 510, e.g., based on RF parameters and/or wireless device location. For example, the centralized uplink technology controller of the access node 520 may evaluate CP-OFDM and DFT-s-OFDM for the device. While CP-OFDM provides more spectral efficiency, the centralized uplink technology controller will estimate the maximum throughput for the two technologies. In the cell center, the centralized uplink technology controller may instruct the wireless device to utilize CP-OFDM because of high spectral efficiency. In selecting between uplink CA and MIMO, the centralized uplink technology controller of the access node 520 may calculate maximum throughput that can be achieved using each technology. While MIMO improves data rates through smart antenna technology, carrier aggregation makes the best use of available frequency carriers. ([0072])
Cheng (US 2013/0156080) discloses the antenna deployment manager 135 is configured to perform antenna deployment switching based on receive signal conditions of the antennas, such as using Receive Signal Strength Indicator (RSSI) detection. RSSI is a measurement of the power present in a received radio signal. This can be done to improve diversity or MIMO performance. This can also be done to improve SAR. In one embodiment, the user device may use four antennas on each side of the user device, such as tablet computer. When an antenna is close to the human body part, such as the hand, performance of the antenna may be impacted. The antennas performance may be determined by monitoring the RSSI of each of the antennas. If the Tx antenna is arranged to a human body part, the effects of SAR may increase too, possibly failing to comply with SAR requirements. The antenna deployment manager 135 can switch the Tx paths between the four antennas based on RSSI monitoring. If the RSSI of the current Tx antenna drops below a defined threshold, the antenna deployment manager 135 can switch the Tx path to the antenna which has the best RSSI. For HSPA+ diversity or MIMO, switching the Tx path to the antenna with the best RSSI and switching the diversity antenna or a second MIMO antenna to the antennas with the second best RSSI. In another embodiment, the antenna deployment manager 135 can use the receive signal condition to effectively determine an orientation of the user device, and to the Tx antenna to be one of the four antennas with the best receive signal condition, regardless of its current position for the current orientation.
