1. A method in a User Equipment (UE) for multi-antenna transmission, comprising:
transmitting a Physical Random Access Channel (PRACH) in a first time interval, the PRACH being associated information;
receiving a Physical Downlink Shared Channel (PDSCH) in a second time interval, the PDSCH comprising second information;
determining one of the first information and the second information to be a target information for a Physical Downlink Control Channel (PDCCH) monitoring based on a rule that the first time and first time window each occurs before a third time interval for the PDCCH monitoring, the second information is used as the target information, and beam information of the PDCCH is determined according to the second information from the base station when the second time interval belongs to the first time window; and if the second time interval does not belong to the first time window, the first information is used as the target information, and beam information of the PDCCH is determined according to the first information when the second time interval does not belong to the first time window; and
monitoring the PDCCH in the third time interval according to the determined target information, a time-domain position of the third time interval being associated to a time-domain position of the first time interval.
