A base station receives measurement capability indication information and indication information indicating a capability of receiving data transmission that are reported by a UE. The base station selects a measurement set for the UE according to the measurement capability indication information, and sends the measurement set to the UE, where the indication information indicating the capability of receiving data transmission includes information of carriers on which the UE supports concurrent receiving of data transmission and the measurement capability indication information includes indication information indicating a capability of the UE for measuring CSI and/or indication information indicating a capability of the UE for measuring RSRP. The base station can flexibly select an activated carrier set for the UE.

    摘要: A method, system, and device for downlink transmission. A downlink signal is sent to a UE in an available frequency band of an uplink frequency band, and no signal is sent or received in a guard frequency band of the uplink frequency band, where the guard frequency band is located in a highest-frequency part and/or a lowest-frequency part of the uplink frequency band. Because no signal is sent or received in the guard frequency band of the uplink frequency band, interference to communication of a UE in an adjacent frequency band is reduced when the uplink frequency band is occupied for downlink transmission, thereby improving system performance.
