Embodiments of the present invention provide an access method and device. The method comprises: determine that N second receiving devices communicate with a second sending device by using radio resources, N being a positive integer greater than or equal to 1; acquire a receive effective channel vector from each second receiving device to a first sending device; acquire a spatial correlation matrix of a transmit antenna of the first sending device; determine M transmit vectors; and the first sending device separately communicates with K first receiving devices by using K transmit vectors among the M transmit vectors, K being a positive integer less than or equal to M. In the technical scheme, in a case in which radio resources are occupied by a second receiving device, the first sending device can send data by using the radio resources. In this manner, the use efficiency of the radio resources is improved; and the first sending device does not interfere with communication of the second receiving device and a second sending device. |
