Abstract

Provided are a method and apparatus for reporting UE capability in a wireless communication system, and an operation method of a UE in the wireless communication system includes receiving a UE capability inquiry message including information about a new radio (NR) frequency band from a BS, generating UE capability information by considering an additional UE capability supported for a supplementary uplink (SUL) as being equal to an additional UE capability supported for frequency division duplex (FDD) when the information about the NR frequency band includes information about a frequency band related to the SUL and the UE supports the frequency band related to the SUL, and transmitting the generated UE capability information to the BS.

Claims (22)

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

receiving a UE capability inquiry message including information about a new radio (NR) frequency band from a base station;

identifying whether an additional UE capability different from a UE capability indicated previously is supported for a supplementary uplink (SUL), in case that the UE supports the SUL;

configuring a parameter related to the additional UE capability supported for the SUL in frequency division duplex (FDD) additional UE capability information, in case that the additional UE capability different from the UE capability indicated previously is supported for the SUL; and

transmitting UE capability information including the FDD additional UE capability information to the base station.

2. The method of claim 1 , wherein the UE capability indicated previously comprises a UE capability applied to the UE regardless of a duplex mode and a frequency band.

3. The method of claim 1 , further comprising:

identifying whether an additional UE capability different from the UE capability indicated previously is supported for a supplementary downlink (SDL), in case that the UE supports the SDL; and

configuring a parameter related to the additional UE capability supported for the SDL in time division duplex (TDD) additional UE capability information, in case that the additional UE capability different from the UE capability indicated previously is supported for the SDL,

wherein the UE capability information further includes the TDD additional UE capability information.

4. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to:

receive a UE capability inquiry message including information about a new radio (NR) frequency band from a base station through the transceiver,

identify whether an additional UE capability different from a UE capability indicated previously is supported for a supplementary uplink (SUL), in case that the UE supports the SUL,

configure a parameter related to the additional UE capability supported for the SUL in frequency division duplex (FDD) additional UE capability information, in case that the additional UE capability different from the UE capability indicated previously is supported for the SUL, and

transmit UE capability information including the FDD additional UE capability information to the base station through the transceiver.

5. The UE of claim 4 , wherein the UE capability indicated previously comprises a UE capability applied to the UE regardless of a duplex mode and a frequency band.

6. The UE of claim 4 , wherein the at least one processor is configured to:

identify whether an additional UE capability different from the UE capability indicated previously is supported for a supplementary downlink (SDL), in case that the UE supports the SDL, and

configure a parameter related to the additional UE capability supported for the SDL in time division duplex (TDD) additional UE capability information, in case that the additional UE capability different from the UE capability indicated previously is supported for the SDL,

wherein the UE capability information further includes the TDD additional UE capability information.
