Claim 5:
6. A method for multi-antenna transmitting in a base station, comprising:
transmitting a first wireless signal;
receiving a second wireless signal;
transmitting a first signaling in a first sub-time resource pool;
transmitting second information; and
transmitting the first signaling in a second time resource pool;
wherein the first wireless signal is transmitted by K antenna port groups; the second wireless signal is used to determine a first antenna port group; the first antenna port group is one of the K antenna port groups; an index of the first antenna port group in the K antenna port groups is used to determine the first sub-time resource pool; the first sub-time resource pool is non-contiguous in time domain; one antenna port group in the K antenna port groups includes a positive integer number of antenna port/ports; and the K is a positive integer greater than 1; the first wireless signal includes one or more of PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), and MIB (Master Information Block)/SIB (System Information Block); the second wireless signal is a RACH (Random Access Channel) preamble, and at least one of a sequence of the RACH preamble and a time-frequency resource occupied by the RACH preamble is used to determine the first antenna port group; the first signaling is non-UE-specific and the first signaling is transmitted on PDCCH (Physical Downlink Control Channel); the second information is used to determine the second time resource pool, the second time resource pool is unrelated to the index of the first antenna port group in the K antenna port groups, and the second time resource pool is non-contiguous in time domain.
