Abstract
This application relates to the communication field, and in particular, to a beam indication method and apparatus, and a terminal. The method includes: obtaining a unified TCI state pool, where the unified TCI state pool is used for a separate TCI state pool or a joint TCI state pool; and performing separate or joint TCI state indication based on the unified TCI state pool.

-30. (canceled)
A method, comprising:
- generating a radio resource control (RRC) signaling with an indication field, wherein the indication field indicates joint indication or separate indication for transmission configuration indication (TCI) states;
- wherein:
- the indication field indicates the joint indication for TCI states, and a first resource pool, configured by a physical downlink shared channel configuration (PDSCH-Config) information element, is for TCI state joint indication, or
- the indication field indicates the separate indication for TCI states, an uplink TCI state pool, configured by an uplink (UL)-bandwidth part (BWP) information element, is for uplink TCI state indication, and the first resource pool, configured by the PDSCH-Config information element, is for downlink TCI state indication;
- and
- transmitting the RRC signaling.
An apparatus, comprising:
- at least one processor, and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to enable the apparatus to:
- generate a radio resource control (RRC) signaling with an indication field, wherein the indication field indicates joint indication or separate indication for transmission configuration indication (TCI) states;
- wherein:
- the indication field indicates the joint indication for TCI states, and a first resource pool, configured by a physical downlink shared channel configuration (PDSCH-Config) information element, is for TCI state joint indication, or
- the indication field indicates the separate indication for TCI states, an uplink TCI state pool, configured by an uplink (UL)-bandwidth part (BWP) information element, is for uplink TCI state indication, and the first resource pool, configured by the PDSCH-Config information element, is for downlink TCI state indication;
- and
- transmit the RRC signaling.
A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer instructions being executed by an apparatus to enable the apparatus to perform:
- generating a radio resource control (RRC) signaling with an indication field, wherein the indication field indicates joint indication or separate indication for transmission configuration indication (TCI) states;
- wherein:
- the indication field indicates the joint indication for TCI states, and a first resource pool, configured by a physical downlink shared channel configuration (PDSCH-Config) information element, is for TCI state joint indication, or
- the indication field indicates the separate indication for TCI states, an uplink TCI state pool, configured by an uplink (UL)-bandwidth part (BWP) information element, is for uplink TCI state indication, and the first resource pool, configured by the PDSCH-Config information element, is for downlink TCI state indication;
- and
- transmitting the RRC signaling.
