Disclosed are a multiplexing sending and receiving method and device for a discovery signal and a physical downlink shared channel. The method comprises: over a data sending time period, a base station determining a sub-frame that sends a DRS within the data sending time period; and performing multiplexing sending on a PDSCH on the sub-frame that sends the DRS within the data sending time period, or performing multiplexing sending on a PDSCH only on a sub-frame 0 and/or a sub-frame 5 that sends the DRS within the data sending time period. The present application solves the problem of how to perform multiplexing sending and receiving on an LAA DRS and the PDSCH within the data sending time period and a PDSCH rate matching problem.
