METHOD AND USER EQUIPMENT FOR BEAM INDICATION IN MTRP

1 - 14 . (canceled)

15 . A method performed by a user equipment (UE) for beam indication in a multi-transmission and reception point (MTRP), the method comprising:

receiving, from a base station (BS), first downlink control information (DCI) including a first transmission configuration indication (TCI) field indicating a first TCI state, the first DCI being associated with a first value;

receiving, from the BS, second DCI including a second TCI field indicating a second TCI state, the second DCI being associated with a second value;

performing, based on the first TCI state, a first uplink (UL) transmission; and

performing, based on the second TCI state, a second UL transmission, wherein:

the first UL transmission is scheduled by third DCI associated with the first value, and

the second UL transmission is scheduled by fourth DCI associated with the second value.

16 . The method of claim 15 , further comprising:

receiving, from the BS, a radio resource control (RRC) configuration including an RRC parameter indicating a TCI state type in a serving cell, wherein:

the RRC parameter indicates a joint TCI state type, and

the first TCI state and the second TCI state are configured in a joint TCI state list.

17 . The method of claim 15 , further comprising:

receiving, from the BS, a radio resource control (RRC) configuration including an RRC parameter indicating a TCI state type in a serving cell, wherein:

the RRC parameter indicates a separate TCI state type, and

the first TCI state and the second TCI state are configured in a UL TCI state list.

18 . The method of claim 15 , wherein the first DCI and the second DCI are downlink (DL) DCI.

19 . The method of claim 15 , wherein the third DCI and the fourth DCI are UL DCI.

20 . A user equipment (UE) for beam indication in a multi-transmission and reception point (MTRP), the UE comprising:

one or more processors; and

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

receive, from a base station (BS), first downlink control information (DCI) including a first transmission configuration indication (TCI) field indicating a first TCI state, the first DCI being associated with a first value;

receive, from the BS, second DCI including a second TCI field indicating a second TCI state, the second DCI being associated with a second value;

perform, based on the first TCI state, a first uplink (UL) transmission; and

perform, based on the second TCI state, a second UL transmission, wherein:

the first UL transmission is scheduled by third DCI associated with the first value, and

the second UL transmission is scheduled by fourth DCI associated with the second value.

21 . The UE of claim 20 , wherein the one or more computer-executable instructions, when executed by the one or more processors, further cause the UE to:

receive, from the BS, a radio resource control (RRC) configuration including an RRC parameter indicating a TCI state type in a serving cell, wherein:

the RRC parameter indicates a joint TCI state type, and

the first TCI state and the second TCI state are configured in a joint TCI state list.

22 . The UE of claim 20 , wherein the one or more computer-executable instructions, when executed by the one or more processors, further cause the UE to:

receive, from the BS, a radio resource control (RRC) configuration including an RRC parameter indicating a TCI state type in a serving cell, wherein:

the RRC parameter indicates a separate TCI state type, and

the first TCI state and the second TCI state are configured in a UL TCI state list.

23 . The UE of claim 20 , wherein the first DCI and the second DCI are downlink (DL) DCI.

24 . The UE of claim 20 , wherein the third DCI and the fourth DCI are UL DCI.

25 . A base station (BS) for beam indication in a multi-transmission and reception point (MTRP), the BS comprising:

one or more processors; and

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

transmit, to a user equipment (UE), first downlink control information (DCI) including a first transmission configuration indication (TCI) field indicating a first TCI state, the first DCI being associated with a first value;

transmit, to the UE, second DCI including a second TCI field indicating a second TCI state, the second DCI being associated with a second value;

perform, based on the first TCI state, a first uplink (UL) reception; and

perform, based on the second TCI state, a second UL reception, wherein:

the first UL reception is scheduled by third DCI associated with the first value, and

the second UL reception is scheduled by fourth DCI associated with the second value.

26 . The BS of claim 25 , wherein the one or more computer-executable instructions, when executed by the one or more processors, further cause the BS to:

transmit, to the UE, a radio resource control (RRC) configuration including an RRC parameter indicating a TCI state type in a serving cell, wherein:

the RRC parameter indicates a joint TCI state type, and

the first TCI state and the second TCI state are configured in a joint TCI state list.

27 . The BS of claim 25 , wherein the one or more computer-executable instructions, when executed by the one or more processors, further cause the BS to:

transmit, to the UE, a radio resource control (RRC) configuration including an RRC parameter indicating a TCI state type in a serving cell, wherein:

the RRC parameter indicates a separate TCI state type, and

the first TCI state and the second TCI state are configured in a UL TCI state list.

28 . The BS of claim 25 , wherein the first DCI and the second DCI are downlink (DL) DCI.

29 . The BS of claim 25 , wherein the third DCI and the fourth DCI are UL DCI.
