First claim

The invention claimed is:

1 . A signal transmission method, comprising:
reporting, by a user equipment (UE) to a base station, a measurement processing capability and an antenna adjustment capability, wherein the measurement processing capability indicates whether the UE needs reference signals for multiple moments in time to complete measurements of different antennas or the UE needs reference signals only for one moment in time to complete measurements of different antennas; measuring channel state information according to one or more measurement antenna configurations based on channel state measurement configuration information configured by the base station, wherein:
in case that the measurement processing capability indicates that the UE needs reference signals for multiple moments in time to complete measurements of difference antennas, the channel state measurement configuration information indicates the reference signals for multiple moments in time and the channel state information is measured using the reference signals for multiple moments in time, and
in case that the measurement processing capability indicates that the UE needs reference signals only for one moment in time to complete measurements of different antennas, the channel state measurement configuration information indicates that the UE needs reference signals only for one moment in time and the channel state information is measured using the reference signals only for one moment in time;
determining, by the UE based on the channel state information measured according to the one or more measurement antenna configurations, that antennas of the UE to be used for a reception of a downlink signal and/or transmission of an uplink signal need to be adjusted; determining, by the UE, a manner for adjusting the antennas of the UE based on a beam failure result obtained based on the channel state information according to the one or more measurement antenna configurations, wherein the beam failure result is obtained according to whether a measured error rate is greater than a specific value; adjusting the of the UE according to the determined manner; and performing, by the UE, reception of the downlink signal and/or transmission of the uplink signal by using the adjusted antennas.

2 . The signal transmission method according to claim 1 , wherein the manner for adjusting the antennas of the UE comprises at least one of the following:
increasing a number of the antennas of the UE to be used for a reception of a downlink signal and/or transmission of an uplink signal; reducing the number of the antennas of the UE to be used for a reception of a downlink signal and/or transmission of an uplink signal; adjusting all of the antennas of the UE to be used for a reception of a downlink signal and/or transmission of an uplink signal to a first particular antenna; and adjusting part of the antennas of the UE to be used for a reception of a downlink signal and/or transmission of an uplink signal to a second particular antenna.

6 . The signal transmission method according to claim 3 , wherein performing channel state measurement on one or more sets of reference signals by the UE, comprises:
identifying the one or more measurement antenna configurations for the channel state measurement according to base station configuration and/or autonomous selection; and performing the channel state measurement on one or more sets of reference signals based on the one or more measurement antenna configurations.

7 . The signal transmission method according to claim 1 ,
wherein, determining, by a user equipment (UE) based on the channel state information measured according to one or more measurement antenna configurations, that antennas of the UE to be used for a reception of a downlink signal and/or transmission of an uplink signal need to be adjusted based on at least one of the following: a relationship between the channel state information measured based on the one or more measurement antenna configurations and a threshold range corresponding to respective channel state information; a relationship between a difference of the channel state information measured based on different measurement antenna configurations and a corresponding threshold value; and the beam failure result measured based on the one or more measurement antenna configurations.
