METHOD FOR MIXEDLY INDICATING UPLINK AND DOWNLINK BEAMS, BASE STATION, TERMINAL AND SYSTEM

摘要

Disclosed is a method for mixedly indicating uplink and downlink beams, comprising: a base station notifies correlations between properties of an uplink access signal and an uplink beam index and/or downlink beam index in a preset manner and/or in a manner of system message configuration, wherein the properties of the uplink access signal are used for indicating the uplink beam index and/or downlink beam index for sending the uplink access signal; and after receiving the uplink access signal, the base station obtains the uplink beam index and/or downlink beam index by recognizing the properties of the uplink access signal. Further disclosed at the same time are a base station, terminal and system for realizing the method.
