Abstract: Embodiments of the present invention relate to the communications field and disclose a data transmission device, method, and system, so as to better improve an average downlink throughput of UE. A specific solution is: A determining unit determines a downlink frequency shift according to a received uplink signal sent by a terminal device, and determines a second transmit frequency according to the downlink frequency shift and a first transmit frequency; and a sending unit sends a downlink signal to the terminal device according to the second transmit frequency determined by the determining unit, so that the terminal device receives the downlink signal according to a receive frequency corresponding to the first transmit frequency, where the downlink signal includes at least one of a DMRS or downlink data. The present invention is applied in a data transmission process.

Abstract: The present disclosure relates to communication methods and devices. One example access network device includes at least one processor configured to generate requirement indication information. The requirement indication information is used to indicate a radio resource management (RRM) requirement to be satisfied by a user equipment (UE). The RRM requirement is suitable for a high-speed mobile communication environment. The example access network device also includes a transmitter configured to send the requirement indication information to the UE.
