1. A method for indicating antenna panel information of a terminal, comprising:
receiving, by the terminal, first configuration information of a first sounding reference signal (SRS) resource set sent by a network side device, wherein the first configuration information of the first SRS resource set comprises an identifier of the first SRS resource set, and the identifier of the first SRS resource set is used to indicate an identifier of an antenna panel of the terminal,
wherein the first configuration information of the first SRS resource set further comprises usage indication information, and the usage indication information indicates that the first configuration information of the first SRS resource set is only used to indicate the identifier of the antenna panel of the terminal and the first configuration information of the first SRS resource set does not configure an SRS resource for SRS transmission;
determining, by the terminal, the identifier of the antenna panel of the terminal according to the identifier of the first SRS resource set, and not transmitting an SRS in association with the first configuration of the first SRS resource set; and
receiving, by the terminal, second configuration information of a second SRS resource set sent by the network side device, wherein the second SRS resource set is used for beam management;
wherein a sum of a number of first SRS resource sets and a number of second SRS resource sets is equal to a number of antenna panels of the terminal, the first SRS resource sets including the first SRS resource set, the second SRS resource sets including the second SRS resource set, and the antenna panels including the antenna panel, and
the identifier of the antenna panel of the terminal is indicated by using the identifier of the first SRS resource set belonging to a first component carrier or a first bandwidth part (BWP) and a second identifier of another first SRS resource set belonging to a second component carrier or a second bandwidth part (BWP), wherein the second identifier of the another first SRS resource set is the same as the identifier of the first SRS resource set, the first SRS resource sets further including the another first SRS resource set.
