Abstract: The present disclosure provides a method and device for multi-antenna transmission in UE and base station. The user equipment receives a first wireless signal at first; then transmits a second wireless signal, and monitors a first signaling in a first sub-time resource pool. Wherein the first wireless signal is transmitted by K antenna port group(s) and the second wireless signal is used to determine the first antenna port group. The first antenna port group is one of the K antenna port group(s).

Compared to conventional non-coherent communication techniques in which a uniform protection is applied to any fraction of differential phase rotation or any bit of a differential symbol, the proposed MLCM approach enables more spectrally efficient scheme.
