Claim 3:
4. A UE for multi-antenna transmission, comprising:
a first transceiver, to transmit a first radio signal in a first time interval, and to receive a second radio signal in a second time interval; and
a first receiver, to monitor a third radio signal in a third time interval;
wherein the first radio signal is associated with first information, and the second radio signal 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 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 and an antenna virtualization for receiving; the target information is provided by the UE when the target information comprises the first information, the target information is receive by the UE from a base station when the target information comprises the second information; the first time interval and the second time interval occur before the third time interval, a first time window occurs before the third time interval; if the second time interval belongs to a first time window, the target information comprises the second information, and the UE determines beam information of the third radio signal according to an indication from the base station; if the second time interval does not belong to a first time window, the target information 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 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 Physical Downlink Control Channel (PDCCH); and the second radio signal is one of a Physical Downlink Shared Channel (PDSCH), a Short Latency PDSCH (SPDSCH) or a New Radio-PDSCH (NR-PDSCH).
