Abstract: The present invention relates to the field of communications technologies, and discloses a retransmission method and apparatus, and a communication system. The method includes: after sending two channel-coded codewords in initial transmission, receiving a retransmission indication, where the retransmission indication includes an identifier of one channel-coded codeword to be retransmitted; according to a preset phase of each symbol, determining a precoding matrix of each symbol of the one channel-coded codeword to be retransmitted, where a phase relationship of each symbol is fixed; and after coding, by using the precoding matrix, each symbol of the one channel-coded codeword to be retransmitted, transmitting the coded symbol through an antenna. Through the present invention, a guarantee can be provided for retransmission success of a UE.

Abstract: The present invention discloses a method, system and apparatus of multi-subframe scheduling. The method of multi-subframe scheduling comprises: sending a terminal a continuous scheduling indication, a first Hybrid Automatic Repeat Request (HARQ) process number corresponding to a first scheduled subframe, and a scheduling configuration parameter of multi-subframe scheduling; acquiring a second HARQ process number corresponding to a currently-scheduling subframe according to the first HARQ process number corresponding to the first scheduled subframe and the continuous scheduling indication, and performing a data packet transmission of the corresponding second HARQ process number in the currently-scheduling subframe by using the scheduling configuration parameter, each scheduled subframe of the multi-subframe scheduling carrying one data packet, and each scheduled subframe of the multi-subframe scheduling using the scheduling configuration parameter. The embodiments of the present invention may save control signaling overhead of the system and improve spectrum efficiency of the system.
