Abstract
A method of sending a TCI, a network-side device and a terminal device are provided. The method includes selecting, based on a link type, a channel, a RS type, or a CORESET, at least one TCI state from configured candidate TCI states, to establish a TCI state table including correspondence between the TCI state and an RS set, or correspondence among the TCI state, the RS set, and a QCL type, or correspondence between the TCI state and a channel type; sending the TCI state table and an identifier of the link type, the channel, the RS type or the CORESET corresponding to the TCI state table.

A method of sending a transmission configuration indication (TCI) state, applied to a network-side device, comprising:
- selecting, based on a link type, a channel, a Reference Signal (RS) type, or a Control Resource Set (CORESET), at least one TCI state from a plurality of candidate TCI states configured in advance, to establish a TCI state table, wherein, the TCI state table comprises correspondence relationship between the TCI state and an RS set, correspondence relationship among the TCI state, the RS set, and a Quasi-Co-Location (QCL) type, or correspondence relationship between the TCI state and a channel type;
- sending the TCI state table and an identifier of the link type, the channel, the RS type or the CORESET corresponding to the TCI state table;
- wherein after sending the TCI state table and the identifier of the link type, the channel, the RS type or the CORESET corresponding to the TCI state table, the method further comprises:
- sending TCI state indication information, wherein the TCI state indication information carries a target TCI state in the TCI state table.
A network-side device, comprising:
- a processor;
- and
- a storage configured to store a computer-executable instruction, wherein when the computer-executable instructions is executed, the processor performs the method according to 1.
A method of sending a transmission configuration indication (TCI) state, applied to a terminal device, comprising:
- receiving a TCI state table and an identifier of a link type, a channel, a Reference Signal (RS) type or a Control Resource Set (CORESET) corresponding to the TCI state table, wherein the TCI state table is generated by a network-side device through selecting, based on the link type, the channel, the RS type or the CORESET, at least one TCI state from a plurality of candidate TCI states configured in advance, the TCI state table comprises correspondence relationship between a TCI state and an RS set, or correspondence relationship among the TCI state, the RS set, and a QCL type, or correspondence relationship between the TCI state and a channel type;
- establishing a TCI state table corresponding to the link type, the channel, the RS type or the CORESET based on the TCI state table and the identifier of the link type, the channel, the RS type or the CORESET corresponding to the TCI state table;
- wherein, after establishing the TCI state table, the method further comprises:
- receiving TCI state indication information, wherein the TCI state indication information carries a target TCI state in the TCI state table.
A terminal device, comprising:
- a processor;
- and a storage configured to store a computer-executable instruction, wherein when the computer-executable instructions is executed, the processor performs a method of sending a transmission configuration indication (TCD) state, applied to a terminal device, comprising:
- receiving a TCI state table and an identifier of a link type, a channel, a Reference Signal (RS) type or a Control Resource Set (CORESET) corresponding to the TCI state table, wherein the TCI state table is generated by a network-side device through selecting, based on the link type, the channel, the RS type or the CORESET, at least one TCI state from a plurality of candidate TCI states configured in advance, the TCI state table comprises correspondence relationship between a TCI state and an RS set, or correspondence relationship among the TCI state, the RS set, and a QCL type, or correspondence relationship between the TCI state and a channel type;
- establishing a TCI state table corresponding to the link type, the channel, the RS type or the CORESET based on the TCI state table and the identifier of the link type, the channel, the RS type or the CORESET corresponding to the TCI state table;
- receiving TCI state indication information, wherein the TCI state indication information carries a target TCI state in the TCI state table.
