Abstract

This application provides methods and apparatuses for updating beam information. One method includes: receiving beam update information of a first component carrier (CC), and updating, based on the beam update information of the first CC, beam information of the first CC and beam information of one or more second CCs associated with the first CC.

Claims (42)

1 . A method for updating beam information, comprising:

receiving, by a communications apparatus, information about a time-frequency tracking reference signal resource configured for a first component carrier (CC) and information about a time-frequency tracking reference signal resource configured for one or more second CCs associated with the first CC;

receiving, by the communications apparatus, beam update information of the first CC indicating the communications apparatus to update beam information of the first CC, wherein the beam update information of the first CC comprises information about an active transmission configuration indicator state (TCI-state) of the first CC; and

in response to receiving the beam update information of the first CC, updating, by the communications apparatus based on the beam update information of the first CC, the beam information of the first CC and beam information of the one or more second CCs associated with the first CC, wherein updating the beam information comprises activating, based on the active TCI-state of the first CC, a TCI-state of the first CC and a TCI-state of the one or more second CCs to generate the active TCI-state of the first CC and an active TCI-state of the one or more second CCs same as the active TCI-state of the first CC.

2 . The method according to claim 1 , wherein the one or more second CCs and the first CC are comprised in one group.

3 . The method according to claim 1 , the method further comprises:

before receiving the beam update information of the first CC, receiving beam configuration information of the first CC, and indication information indicating that the one or more second CCs are associated with the first CC.

4 . The method according to claim 1 , wherein

the one or more second CCs and the first CC have a same beam configuration.

5 . The method according to claim 1 , wherein

updating the beam information of the one or more second CCs comprises:

updating information about quasi-co-location (QCL)-TypeA or QCL-TypeD of the one or more second CCs based on the beam update information of the first CC, wherein a time-frequency tracking reference signal resource associated with the QCL-TypeA of the one or more second CCs is the time-frequency tracking reference signal resource of the one or more second CCs.

6 . The method according to claim 5 , wherein a configuration of the QCL-TypeA or the QCL-TypeD is absent of a CC identifier, and wherein the method further comprising:

sending a reference signal of the QCL-TypeA or the reference signal of the QCL-TypeD on a frequency domain resource without the CC identifier.

7 . The method according to claim 1 , wherein

updating the beam information of the first CC and the beam information of the one or more second CCs comprises:

updating a spatial relationship of the one or more second CCs to generate an updated spatial relationship of the one or more second CCs associated with the active TCI-state of the first CC.

8 . The method according to claim 1 , wherein the active TCI-state of the one or more second CCs and the active TCI-state of the first CC are TCI-states of control resource sets with a same control resource set identifier (ID).

9 . The method according to claim 1 , wherein the beam update information of the first CC is carried in medium access control-control element (MAC-CE) signaling, and a reserved field in the MAC-CE signaling indicates whether to update the beam information of the one or more second CCs and the beam information of the first CC based on the beam update information of the first CC.

10 . The method according to claim 1 , wherein:

the active TCI-state of the one or more second CCs and the active TCI-state of the first CC are used to transmit one or more of: PUSCH, SRS, or PUCCH; or

the active TCI-state of the one or more second CCs and the active TCI-state of the first CC are used to receive one or more of: PDCCH, PDSCH, or CSI-RS.

11 . A communications apparatus, comprising:

at least one processor communicably coupled to one or more memories storing programming instructions for execution by the at least one processor to perform operations comprising:

receiving information about a time-frequency tracking reference signal resource configured for a first component carrier (CC) and information about a time-frequency tracking reference signal resource configured for one or more second CCs associated with the first CC;

receiving beam update information of the first CC indicating the communications apparatus to update beam information of the first CC, wherein the beam update information of the first CC comprises information about an active transmission configuration indicator state (TCI-state) of the first CC; and

in response to receiving the beam update information of the first CC, updating, based on the beam update information of the first CC, beam information of the first CC and beam information of the one or more second CCs associated with the first CC, wherein updating the beam information comprises activating, based on the active TCI-state of the first CC, a TCI-state of the first CC and a TCI-state of the one or more second CCs to generate the active TCI-state of the first CC and an active TCI-state of the one or more second CCs same as the active TCI-state of the first CC.

12 . The communications apparatus according to claim 11 , wherein the one or more second CCs and the first CC are comprised in one group.

13 . The communications apparatus according to claim 11 , wherein the operations further comprising: receiving beam configuration information of the first CC, and indication information indicating that the one or more second CCs are associated with the first CC.

14 . The communications apparatus according to claim 11 , wherein the one or more second CCs and the first CC have a same beam configuration.

15 . The communications apparatus according to claim 11 , wherein update the beam information of the one or more second comprises:

updating information about quasi-co-location (QCL)-TypeA or QCL-TypeD of the one or more second CCs based on the beam update information of the first CC, wherein a time-frequency tracking reference signal resource associated with the QCL-TypeA of the one or more second CCs is the time-frequency tracking reference signal resource of the one or more second CCs.

16 . The communications apparatus according to claim 15 , wherein a configuration of the QCL-TypeA or the QCL-TypeD is absent of a CC identifier, and wherein the operations further comprising:

sending a reference signal of the QCL-TypeA or the reference signal of the QCL-TypeD on a frequency domain resource without the CC identifier.

17 . The communications apparatus according to claim 11 , wherein

updating the beam information of the first CC and the beam information of the one or more second CCs comprises:

updating a spatial relationship of the one or more second CCs to generate an updated spatial relationship of the one or more second CCs associated with the active TCI-state of the first CC.

18 . The communications apparatus according to claim 11 , wherein the active TCI-state of the one or more second CCs and the active TCI-state of the first CC are TCI-states of control resource sets with a same control resource set identifier (ID).

19 . The communications apparatus according to claim 11 , wherein the beam update information of the first CC is carried in medium access control-control element (MAC-CE) signaling, and a reserved field in the MAC-CE signaling indicates whether to update the beam information of the one or more second CCs and the beam information of the first CC based on the beam update information of the first CC.

20 . The communications apparatus according to claim 11 , wherein:

the active TCI-state of the one or more second CCs and the active TCI-state of the first CC are used to transmit one or more of: PUSCH, SRS, or PUCCH; or

the active TCI-state of the one or more second CCs and the active TCI-state of the first CC are used to receive one or more of: PDCCH, PDSCH, or CSI-RS.
