1. A method in a User Equipment (UE) for multi-antenna transmission, comprising:
transmitting a first radio signal in a first time interval; and
receiving a second radio signal in a second time interval; and
monitoring a third radio signal in a third time interval;
wherein the first radio signal comprises is associated with first information, and the second radio signal comprises is associated with second information; target information is used for a multi-antenna related receiving in the third time interval; a time-domain position of the second time interval is used for determining whether the target information is comprises the first information or the second information; and a time-domain position of the third time interval is associated to a time-domain position of the first time interval; the multi-antenna related receiving refers to one of generation of a beamforming matrix for receiving; or the multi-antenna related receiving refers to a receiving corresponding to one multi-antenna transmission scheme in SFBC, STBC, Precoder Cycling or Transmit beamforming; or the multi-antenna related receiving refers to and an antenna virtualization for receiving; the target information is provided by the UE when the target information is comprises the first information, the target information is provided by received by the UE from a base station when the target information is comprises the second information; the base station is a transmitter of the second radio signal; the first time interval and the second time interval are occur before the third time interval respectively, a first time window is occurs before the third time interval; if the second time interval belongs to the first time window, the target information is comprises the second information, and the UE determines beam information of the third radio signal according to the an indication from the base station; if the second time interval does not belong to the first time window, the target information is comprises the first information, and the UE receives the third radio signal according to its own reporting in the first information; the third radio signal is used for transmitting a Downlink Control Information (DCI), and the UE performs blind decoding of the third radio signal in the third time interval; a physical layer channel corresponding to the third radio signal is a Physical Downlink Control Channel (PDCCH); and the second radio signal is one of a Physical Downlink Shared Channel (PDSCH), a Short Latency PDSCH (SPDSCH), and a New Radio-PDSCH (NR-PDSCH).
