Claim 0:
1. A beam indication method, comprising:
receiving beam indication information transmitted by a network-side device, wherein the beam indication information is used to indicate a plurality of pieces of beam information of a channel or a reference signal, and the plurality of pieces of beam information correspond to different transmission and reception point TRP identification information; and
transmitting the channel or the reference signal according to the beam indication information;
wherein the channel comprises a PDSCH; and
if there is no TCI field in downlink control information DCI for scheduling the PDSCH, a mode of the DCI is a single-DCI mode, and the beam indication information comprises:
TCI state information of a PDCCH on which the DCI is located; or
a plurality of pieces of TCI state information corresponding to a lowest codepoint among codepoints containing a plurality of pieces of TCI state information in a TCI field of the DCI, wherein the plurality of pieces of TCI state information correspond to different TRP identification information; or
if there is no TCI field in DCI for scheduling the PDSCH, a mode of the DCI is a multi-DCI mode, and the beam indication information comprises:
TCI state information of a PDCCH on which the DCI is located;
or
wherein the channel comprises a PDSCH; and the beam indication information comprises:
a plurality of sounding reference signal resource indicators, wherein a plurality of sounding reference signal resources are associated with different TRP identification information; or
one sounding reference signal resource indicator having a plurality of pieces of spatial relation information, wherein the plurality of pieces of spatial relation information are associated with different TRP identification information; or
one sounding reference signal resource indicator having spatial relation information of a plurality of source reference signals, wherein the plurality of source reference signals are associated with different TRP identification information.
