<p>An indication method and a base station for Space Division Multiple Access (SDMA) transmission are provided, the method comprises: when the SDMA transmission is adopted in the Long Term Evolution (LTE) system, the power allocation information is disposed in the Downlink Control Information (DCI), so as to indicate the terminal to perform demodulation based on the power allocation information (11); the DCI containing the power allocation information is transmitted to the terminal (12). The base station comprises a disposing module and a transmission module, or only comprises a transmission module. The above-mentioned technical proposal allows the terminals which use different beam for transmission to acquire respective power allocation information by means of disposing power allocation information in the transmission signal, consequently the indication for SDMA transmission is realized, the space division multiplex technique that plurality of users multiplexing one and the same time-frequent resource is supported, and the utilization ratio is effectively enhanced.</p> |
