Disclosed are a method and device for transmitting indication information. The method comprises: determining a first signature sequence and a first modulation constellation used for transmitting a first downlink data stream to a terminal device; determining one or more second signature sequences and one or more second modulation constellations used for transmitting a second downlink data stream; determining indication information used for indicating the first signature sequence, the first modulation constellation, the one or more second signature sequences, and the one or more second modulation constellations; and, transmitting the indication information to the terminal device. The method and device of embodiments of the present invention for transmitting indication information, by transmitting the indication information to the terminal device via a network device, allow the terminal device to determine the signature sequences and modulation constellations used by all downlink data streams borne on a same time-frequency resource, and, with this, allow decoding of the first downlink data stream, thus allowing the network device and the terminal device to transmit downlink data, and allowing effectively increased network capacity of a system. |
