Abstract

Claims (36)

1 . A method for a unified Transmission Configuration Indication (TCI) state operation performed by a user equipment (UE), the method comprising:

receiving a first Radio Resource Control (RRC) configuration for configuring a first set of TCI states and a second set of TCI states;

receiving a first indication for associating the first set of TCI states with a first channel, the first channel comprising a Physical Downlink Control Channel (PDCCH);

receiving a second indication for associating the second set of TCI states with a second channel, the second channel being scheduled by first Downlink Control Information (DCI) received on the first channel;

receiving a third indication for indicating at least one third TCI state to be applied on the second channel; and

transmitting or receiving the second channel after applying the at least one third TCI state.

2 . The method of claim 1 , wherein the at least one third TCI state is associated with the second set of TCI states.

3 . The method of claim 1 , wherein:

the second channel comprises one of a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Control (PUCCH), a Physical Uplink Shared Channel (PUSCH), a reference signal, a set of PDSCH repetitions, a set of PUCCH repetitions, a set of PUSCH repetitions, or a set of reference signal repetitions.

4 . The method of claim 1 , wherein the second channel corresponds to a coherent joint transmission (CJT).

5 . The method of claim 4 , further comprising:

receiving a second RRC configuration for enabling the CJT.

6 . The method of claim 1 , wherein the first set of TCI states is identical to the second set of TCI states.

7 . The method of claim 6 , wherein the second channel comprises a downlink (DL) channel.

8 . The method of claim 6 , wherein the second channel comprises an uplink (UL) channel.

9 . The method of claim 1 , wherein a number of the at least one third TCI state indicated by the third indication is different from a number of TCI states in the second set of TCI states.

10 . The method of claim 1 , wherein the third indication is indicated per BandWidth Part (BWP).

11 . A user equipment (UE) for a unified Transmission Configuration Indication (TCI) state operation, the UE comprising:

one or more processors; and

at least one memory coupled to at least one of the one or more processors, the at least one memory storing computer-executable instructions that, when executed by the at least one of the one or more processors, cause the UE to:

receive a first Radio Resource Control (RRC) configuration for configuring a first set of Transmission Configuration Indication (TCI) states and a second set of TCI states,

receive a first indication for associating the first set of TCI states with a first channel, the first channel comprising a Physical Downlink Control Channel (PDCCH);

receive a second indication for associating the second set of TCI states with a second channel, the second channel being scheduled by first Downlink Control Information (DCI) received on the first channel;

receive a third indication for indicating at least one third TCI state to be applied on the second channel; and

transmit or receive the second channel after applying the at least one third TCI state.

12 . The UE of claim 11 , wherein the at least one third TCI state is associated with the second set of TCI states.

13 . The UE of claim 11 , wherein:

the second channel comprises one of a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Control (PUCCH), a Physical Uplink Shared Channel (PUSCH), a reference signal, a set of PDSCH repetitions, a set of PUCCH repetitions, a set of PUSCH repetitions, or a set of reference signal repetitions.

14 . The UE of claim 11 , wherein the second channel corresponds to a coherent joint transmission (CJT).

15 . The UE of claim 14 , wherein the computer-executable instructions, when executed by the at least one of the one or more processors, further cause the UE to:

receive a second RRC configuration for enabling the CJT.

16 . The UE of claim 11 , wherein the first set of TCI states is identical to the second set of TCI states.

17 . The UE of claim 16 , wherein the second channel comprises a downlink (DL) channel.

18 . The UE of claim 16 , wherein the second channel comprises an uplink (UL) channel.

19 . The UE of claim 11 , wherein a number of the at least one third TCI state indicated by the third indication is different from a number of TCI states in the second set of TCI states.

20 . The UE of claim 11 , wherein the third indication is indicated per BandWidth Part (BWP).
