Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit first capability information indicating a first set of band configurations. The UE may transmit, after the transmission of the first capability information, second capability information indicating a second set of band configurations. The UE may receive information indicating a band configuration, wherein the band configuration that is not included in at least one of the first set of band configurations or the second set of band configurations. The UE may communicate using the band configuration. Numerous other aspects are provided.

Claims (61)

1 . A method of wireless communication performed by a user equipment (UE), comprising:

transmitting first capability information indicating a first set of band configurations;

transmitting, after transmission of the first capability information, second capability information indicating a second set of band configurations;

receiving information indicating a band configuration, wherein the band configuration is not included in at least one of the first set of band configurations or the second set of band configurations;

determining whether the band configuration is supported by the UE,

wherein the UE is associated with a mode in which the determination, of whether the band configuration is supported by the UE, is performed when the band configuration is not indicated by the second capability information; and

communicating using the band configuration.

2 . The method of claim 1 , wherein the band configuration comprises a Long Term Evolution carrier aggregation configuration.

3 . The method of claim 1 , wherein the band configuration comprises a multi radio access technology dual connectivity configuration.

4 . The method of claim 1 , wherein the band configuration comprises a New Radio carrier aggregation configuration.

5 . The method of claim 1 , wherein the band configuration comprises a New Radio dual connectivity configuration.

6 . The method of claim 1 , wherein the band configuration indicates a multiple-input multiple-output configuration for one or more bands.

7 . The method of claim 1 , wherein the band configuration indicates a modulation scheme configuration for one or more bands.

8 . The method of claim 1 , wherein the band configuration relates to a group of bands.

9 . The method of claim 1 , further comprising determining whether to indicate invalid configuration based at least in part on whether the band configuration is supported by the UE.

10 . The method of claim 1 , further comprising:

determining that the band configuration is not indicated by the second capability information; and

determining that the band configuration is supported by the UE based at least in part on the determination that the band configuration is not indicated by the second capability information.

11 . The method of claim 1 , wherein the UE is associated with another mode in which the determination of whether the band configuration is supported by the UE is based at least in part on whether the band configuration is indicated by the second capability information.

12 . The method of claim 1 , wherein the second capability information is most recent capability information transmitted by the UE.

13 . The method of claim 1 , wherein the first capability information is based at least in part on a first capability inquiry for information regarding band combinations and the second capability information is based at least in part on a second capability inquiry for information regarding band combinations.

14 . The method of claim 13 , wherein the first capability inquiry and the second capability inquiry are associated with different sets of band combinations.

15 . A user equipment (UE) for wireless communication, comprising:

one or more antennas; and

a processing system that includes one or more processors and one or more memories that store code and are coupled with the one or more processors, the processing system configured to cause the UE to:

transmit first capability information indicating a first set of band configurations;

transmit, after transmission of the first capability information, second capability information indicating a second set of band configurations;

receive information indicating a band configuration, wherein the band configuration is not included in at least one of the first set of band configurations or the second set of band configurations;

determine whether the band configuration is supported by the UE,

wherein the UE is associated with a mode in which the determination, of whether the band configuration is supported by the UE, is performed when the band configuration is not indicated by the second capability information; and

communicate using the band configuration.

16 . The UE of claim 15 , wherein the band configuration indicates a multiple-input multiple-output configuration for one or more bands.

17 . The UE of claim 15 , wherein the band configuration indicates a modulation scheme configuration for one or more bands.

18 . The UE of claim 15 , wherein the band configuration relates to a group of bands.

19 . The UE of claim 15 , wherein the processing system is further configured to determine whether to indicate invalid configuration based at least in part on whether the band configuration is supported by the UE.

20 . The UE of claim 15 , wherein the processing system is further configured to:

determine that the band configuration is not indicated by the second capability information; and

determine that the band configuration is supported by the UE based at least in part on the determination that the band configuration is not indicated by the second capability information.

21 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:

transmit first capability information indicating a first set of band configurations;

transmit, after transmission of the first capability information, second capability information indicating a second set of band configurations;

receive information indicating a band configuration, wherein the band configuration is not included in at least one of the first set of band configurations or the second set of band configurations;

determine whether the band configuration is supported by the UE,

wherein the UE is associated with a mode in which the determination, of whether the band configuration is supported by the UE, is performed when the band configuration is not indicated by the second capability information; and

communicate using the band configuration.

22 . The non-transitory computer-readable medium of claim 21 , wherein the band configuration indicates a multiple-input multiple-output configuration for one or more bands.

23 . The non-transitory computer-readable medium of claim 21 , wherein the band configuration indicates a modulation scheme configuration for one or more bands.

24 . The non-transitory computer-readable medium of claim 21 , wherein the band configuration relates to a group of bands.

25 . An apparatus for wireless communication, comprising:

means for transmitting first capability information indicating a first set of band configurations;

means for transmitting, after transmission of the first capability information, second capability information indicating a second set of band configurations;

means for receiving information indicating a band configuration, wherein the band configuration is not included in at least one of the first set of band configurations or the second set of band configurations;

means for determining whether the band configuration is supported by the apparatus,

wherein the apparatus is associated with a mode in which the determination, of whether the band configuration is supported by the apparatus, is performed when the band configuration is indicated by the second capability information; and

means for communicating using the band configuration.

26 . The apparatus of claim 25 , wherein the band configuration relates to a group of bands.

27 . The UE of claim 15 , wherein the UE is associated with another mode in which the determination of whether the band configuration is supported by the UE is based at least in part on whether the band configuration is indicated by the second capability information.

28 . The UE of claim 15 , wherein the band configuration comprises a carrier aggregation configuration.

29 . The non-transitory computer-readable medium of claim 21 , wherein the UE is associated with another mode in which the determination of whether the band configuration is supported by the UE is based at least in part on whether the band configuration is indicated by the second capability information.
