Title: USER EQUIPMENT FOR MULTI-ANTENNA TRANSMISSION, AND METHOD AND APPARATUS IN BASE STATION
Abstract:
Disclosed in the present invention are a user equipment for multi-antenna transmission, and a method and an apparatus in a base station. The UE sends a first wireless signal in a first time period, receives a second wireless signal in a second time period, and then monitors a third wireless signal in a third time period. The first wireless signal comprises first information, and the second wireless signal comprises second information. Target information is used for receiving the third wireless signal. The time-domain position of the second time period is used for determining whether the target information is the first information or the second information. The time-domain position of the third time period is associated with the time-domain position of the first time period. In the present invention, by establishing an association between the third time period and the first time period, the UE quickly and flexibly selects the direction of the beamforming corresponding to a downlink channel according to the measurement of the UE, thereby improving the efficiency and performance of downlink transmission.
