Claim of US Patent No. 10,485,009

1. A method in a User Equipment (UE) for wireless communication, comprising:receiving a first radio signal in a first time interval;
conducting blind decoding for the first radio signal in a second time interval, and receiving a second radio signal in a third time interval; and
receiving a third radio signal in a fourth time interval;
wherein the blind decoding for the first radio signal is used for recovering a first signaling, a multi-antenna related receiving for the second radio signal does not depend on the correct decoding of the first radio signal, the second radio signal and the third radio signal are transmitted by a same antenna port, the first signaling is used for determining first scheduling information, the first scheduling information is shared by the second radio signal and the third radio signal, the first scheduling information comprises at least one of {MCS (Modulation Coding Scheme), occupied time-frequency resource, retransmission procedure number, redundancy version, new data indicator, transmitting antenna port}, a end time of the second time interval is behind a start time of the third time interval, and the fourth time interval is behind the third time interval; and
wherein antenna ports used for transmitting the first radio signal, the second radio signal and the third radio signal are all related to a first reference signal spatially, the first reference signal is used for determining a multi-antenna related transmitting and receiving for the first radio signal, the second radio signal and the third radio signal; or, an antenna port used for transmitting the first radio signal is related to the first reference signal spatially, the same antenna port used for transmitting the second radio signal and the third radio signal are related to a second reference signal spatially, the first reference signal differs from the second reference signal, the first reference signal is used for determining the multi-antenna related transmitting and receiving for the first radio signal, and the second reference signal is used for determining the multi-antenna related transmitting for the second radio signal and the multi-antenna related transmitting and receiving for the third radio signal.
