The Type1 UE supports collocated carrier aggregation and for the Type1 UE, both ENDC and NRCA are indicated. The Type2 UE supports non-collocated carrier aggregation. For the Type2 UE, only the inter-band ENDC is indicated. However, with respect to the Type2 UE, it is not indicated for an intra-band NRCA. Therefore, the present disclosure proposes to add definition of the intra-band NRCA for the Type2 UE.”: {0152]);
a memory storing instructions (see fig. 3A: UE with memory: [0092], [0129]-[0130]); and
a processor executing the stored instructions to perform operations (see fig. 3a: processor connected to memory: [0129]-[0131]) including,
receiving at the wireless device capable of CA, a user equipment (UE) capability enquiry from a network (==gNB)) (see fig. 9, UE receiving “ UE CapabalityEnquiry” from gNB: “ Step 2: The network node requests the UE to transmit the capability information, e.g. the network node transmits a “UECapabilityEnquiry” message to the UE. ”: [0287]; UE is NR-CA capable UE: [0289]);
and
sending from the wireless device (==UE), in response to the UE capability enquiry, a UE capability information message (==UE Capability Information Report ) (aforesaid UE sends “UE Capability Information Report” to gNB in response to “UECapabilityEnuiry” “ The UE reports the capability information to the network node based on the request of the network node, e.g., the UE reports a “UECapabilityInformation” message, to report its capability to the network node.”: [0288]; “ It should be noted that the UE may transmit to the network one or more of a first signaling (e.g., which indicates that for intra-band NR-CA, the UE supports the Type2 capability), a second signaling (e.g., which indicates that for intra-band NR-CA or inter-band EN-DC, the UE supports the Type3 or Type4 capability), a third signaling (e.g., which indicates MIMO layer number capability configuration for non-collocated deployment), a fourth signaling (e.g., which indicates Rx Chain number configuration capability), a fifth signaling (e.g., which indicates downlink frequency separation capability for intra-band NR-CA or inter-band EN-DC with overlapping band), a sixth signaling (e.g., which indicates uplink frequency separation capability for intra-band NR-CA or inter-band EN-DC with overlapping band), based on its capability. If the UE reports the first signaling or the second signaling to the network, it indicates that the UE is a UE with a high capability.”[ 0289]).
While ZHANG teaches, UE “ UE capability switching ” in paragraphs [0290]-[0299];
ZHANG does not expressively disclose:
determining, by the UE. an optimized sounding reference signals (SRS) antenna switching configuration during CA based on characteristics of the network:
the UE capability information message having an information element indicating the SRS antenna switching configuration during CA, wherein the optimized SRS antenna switching configuration utilizes fewer antennas than the original SRS antenna switching configuration.
AKULA, in the same field of endeavor, discloses:
determining, by the UE. an optimized sounding reference signals (SRS) antenna switching configuration during CA based on characteristics of the network ( “Aspects of the present disclosure provide methods for improved performance for SRS switching in CA. According to certain aspects, the UE determines bands that can be affected by the SRS antenna switching and sends a list of the affected bands to the BS. These lists could be for various band combinations, such as TDD Tx and FDD Rx, TDD Tx and FDD Tx, and/or TDD Tx and FDD Rx and Tx. The BS can use the list of affected bands to determine (e.g., optimize) scheduling for the UE, for example, to avoid or mitigate the effects of antenna switching on those bands.”: [0086]; also see fig. 11: UE is determining “one or more band combinations (e.g., TDD+FDD CA and/or TDD+5G CA configured band combinations) that share an antenna switch. The bands may be for uplink, downlink, or both uplink and downlink.” : [0088]-[0089]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of ZHANG to include the above recited limitations as taught by AKULA. The suggestion/motivation would be improving performance for sounding reference signal (SRS) antenna switching in carrier aggregation (CA). (AKULA; [0002]).
The combination of ZHANG in View of AKULA does not expressively disclose:
the UE capability information message having an information element indicating the SRS antenna switching configuration during CA, wherein the optimized SRS antenna switching configuration utilizes fewer antennas than the original SRS antenna switching configuration.
GO5730, in the same field of endeavor, discloses:
the UE capability information message having an information element indicating the SRS antenna switching configuration during CA, wherein the optimized SRS antenna switching configuration utilizes fewer antennas than the original SRS antenna switching configuration (see fig. 11-12 element S1110, S1210: “UE may report, to the BS, that the UE capability related to the antenna switching is “1T4R” by considering up to the panel switching.”: [0350]; UE sends to Base Station UE capability which includes SRS antenna switching information : [0242]; “ When a panel switching guard period is defined as the UE capability information, the Rx panel receiving the DL/UL DCI for triggering the SRS and the Tx panel of the indicated SRS may be different.”: [0358]; SRS transmission of antenna switch include UE support for Tx Antenna chains (==LESS SRS antenna in claim ) is LESS than the number or RX antenna chains (==original antenna in claim) : [0384]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of ZHANG in View of AKULA to include the above recited limitations as taught by GO5730. The suggestion/motivation would be to handling of explosively increasing data traffic, significant increase in per-user transmission rate, working with a great number of connecting devices, and support for very low end-to-end latency and high-energy efficiency (GO5730; [0004]).

generating, in response to the UE capability enquiry, a UE capability information message (==UE Capability Information Report ) (aforesaid UE sends “UE Capability Information Report” to gNB in response to “UECapabilityEnuiry” “ The UE reports the capability information to the network node based on the request of the network node, e.g., the UE reports a “UECapabilityInformation” message, to report its capability to the network node.”: [0288]; “ It should be noted that the UE may transmit to the network one or more of a first signaling (e.g., which indicates that for intra-band NR-CA, the UE supports the Type2 capability), a second signaling (e.g., which indicates that for intra-band NR-CA or inter-band EN-DC, the UE supports the Type3 or Type4 capability), a third signaling (e.g., which indicates MIMO layer number capability configuration for non-collocated deployment), a fourth signaling (e.g., which indicates Rx Chain number configuration capability), a fifth signaling (e.g., which indicates downlink frequency separation capability for intra-band NR-CA or inter-band EN-DC with overlapping band), a sixth signaling (e.g., which indicates uplink frequency separation capability for intra-band NR-CA or inter-band EN-DC with overlapping band), based on its capability. If the UE reports the first signaling or the second signaling to the network, it indicates that the UE is a UE with a high capability.”[ 0289]).
While ZHANG teaches, UE “ UE capability switching ” in paragraphs [0290]-[0299];
ZHANG does not expressively disclose:

With respect to dependent claims:
Regarding claim 2, ZHANG in View of AKULA and further in view of GO5730 teaches the invention of claim 1 as set forth above. Further, ZHANG teaches, The method of claim 1, further comprising simultaneously connecting to a primary cell (PCell) of the RAN using time domain duplexing (TDD) and connecting to a secondary cell (SCell) of the RAN using frequency domain duplexing (FDD) (UE is connected with gNB in Fig. 9. Aforesaid gNB can be configured with “ transmission and reception paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuit 374 and/or RX processing circuit 376) support aggregated communication with FDD cells and TDD cells.”: [0144]; “ It should be noted that the first signaling may be designed in a variety of ways, as long as it indicates that the UE supports the non-collocated intra-band NRCA and meets the requirement for the second type of UE. Reporting this signaling indicates that the UE is the Type 2 UE and that the UE supports time-division duplex (TDD) or frequency-division duplex (FDD) intra-band CA and meets the MRTD requirement (MRTD<X μs) as indicated in 38.133 and RF requirements of the Type 2; if the UE does not report this signaling, it indicates that the UE is the Type1 UE, the intra-band CA of TDD or FDD supported by the UE needs to satisfy the MRTD<3 μs as indicated in 38.133 and RF requirements for the Type1 UE.”: [0183]).
Regarding claim 3, ZHANG in View of AKULA and further in view of GO5730 teaches the invention of claim 2 as set forth above. Further, AKULA teaches, wherein the determining comprising determining the optimized the SRS antenna switching configuration based on slot cycle spacing and periodicity ( “ Aspects of the present disclosure provide methods for improved performance for SRS switching in CA. According to certain aspects, the UE determines bands that can be affected by the SRS antenna switching and sends a list of the affected bands to the BS.

The BS can use the list of affected bands to determine (e.g., optimize) scheduling for the UE, for example, to avoid or mitigate the effects of antenna switching on those bands.”: [0086]; slots spacing [0069]-0072]).
Regarding claim 4, ZHANG in View of AKULA and further in view of GO5730 teaches the invention of claim 3 as set forth above. Further, GO5730 teaches
The method of claim 3, wherein the original SRS antenna switching configuration is one Tx and four Rx antennas( 1T4R ) and the optimized SRS antenna switching configuration is one Tx and two Rx antennas (1T2R) (“the capability of the UE related to the antenna switching may be ‘1T2R’, ‘2T4R’, ‘1T4R’, ‘1T4R/2T4R’, ‘1T1R’, ‘2T2R’, ‘4T4R’, etc. Here, ‘mTnR’ may mean a UE capability supporting m transmissions and n receptions.”: [0242]; “ (Sample S1) For example, in the case of a UE that supports 1T2R, up to two SRS resource sets may be configured as different values for resourceType of a higher layer parameter SRS-ResourceSet. Here, each SRS resource set may have two SRS resources transmitted in different symbols, and each SRS resource may constitute a single SRS port in a given SRS resource set. Further, an SRS port for a second SRS resource in the SRS resource set may be configured to be associated with a different UE antenna port from an SRS port for a first SRS resource in the same SRS resource set.
[0244] (Sample S2) As another example, in the case of a UE that supports 2T4R, up to two SRS resource sets may be configured as different values for resourceType of the higher layer parameter SRS-ResourceSet. Here, each SRS resource set may have two SRS resources transmitted in different symbols, and each SRS resource may constitute a single SRS port in a given SRS resource set. Further, an SRS port pair for the second SRS resource in the SRS resource set may be configured to be associated with a different UE antenna port from the SRS port pair for the first SRS resource in the same SRS resource set.
[0245] (Sample S3) As yet another example, in the case of a UE that supports 1T4R, the SRS resource sets may be configured in different schemes according to whether the SRS transmission is configured to be periodic, semi-persistent, and/or aperiodic. First, when the SRS transmission is configured to be periodic or semi-persistent, one SRS resource set constituted by 0 SRS resource set or four SRS resources configured based on for the resourceType of the higher layer parameter SRS-ResourceSet may be configured to be transmitted in different symbols. In this case, each SRS resource may constitute the single SRS port in the given SRS resource set, and the SRS port for each SRS resource may be configured to be associated with different UE antenna ports. Unlike this, when the SRS transmission is configured to be aperiodic, two SRS resource sets constituted by 0 SRS resource set or a total of four SRS resources configured based on for the resourceType of the higher layer parameter SRS-ResourceSet may be configured to be transmitted in different symbols of two different slots. In this case, the SRS ports for respective SRS resources in two given SRS resource sets may be configured to be associated with different UE antenna ports.
[0246] (Sample S4) As still yet another example, in the case of the UE that supports 1T1R, 2T2R, or 4T4R, up to two SRS resource sets of which each is constituted by one SRS resource may be configured for the SRS transmission, and the number of SRS ports of each SRS resource may be configured to 1, 2, or 4.
[0247] When an indicated UE capability is 1T4R/2T4R, the corresponding UE may expect that SRS ports (e.g., 1 or 2) of the same number will be configured for all SRS resources in the SRS resource set(s). Further, when the indicated UE capability is 1T2R, 2T4R, 1T4R, or 1T4R/2T4R, the corresponding UE may not expect that one or more SRS resource sets configured for the antenna switching usage in the same slot will be configured or triggered. Further, even when the indicated UE capability is 1T1R, 2T2R, or 4T4R, the corresponding UE may not expect that one or more SRS resource sets configured for the antenna switching usage in the same slot will be configured or triggered.”: [0242]-[0247] ).
