Communication method, and apparatus

Abstract

A communication method and an apparatus, applied to the technical field of communications. The method comprises: a first communication apparatus receives first information from a second communication apparatus, the first information comprising a first field and / or a second field, the first field indicating a DMRS pattern, the second field indicating a DMRS port, no RRC link being established between the first communication apparatus and the second communication apparatus, and / or a physical shared channel corresponding to the first communication apparatus being scheduled by DCI 1_0 or DCI 0_0; and, on the basis of the first information, the first communication apparatus performs physical shared channel transmission with the second communication apparatus. The embodiments of the present application can achieve flexible configuration of a DMRS pattern and a DMRS port when no RRC link is established between a terminal device and a network device, which is no longer limited to SU-MIMO single-stream transmission, and can also support SU-MIMO multi-stream transmission and MU-MIMO transmission, thereby helping to improve the communication performance of communication systems.
