Abstract: A transmission control method includes sending, by a terminal, uplink control information (UCI) in a first format of the UCI to a radio access network device, where the UCI includes at least one of measurement result information of beam groups or information of the beam groups. The measurement result information of the beam groups includes a measurement result of a first beam group and an offset of a measurement result of a second beam group relative to the measurement result of the first beam group. The measurement result of the first beam group is a reference measurement result, and the information of the beam groups indicates a beam group corresponding to at least one of the measurement result of the first beam group or the measurement result of the second beam group.

Abstract: A reference signal transmission method and a related device and system are disclosed. The method includes: determining, by a first base station, at least one target subframe on a target frequency band, where the target frequency band is a frequency band whose uplink and downlink transmission directions are configurable, and uplink-downlink timeslot configurations and/or transmission directions of the first base station and a neighboring second base station in the at least one target subframe are different; and sending, by the first base station, a first reference signal to first user equipment UE in the at least one target subframe, where the first UE is UE served by the first base station. When embodiments of the present invention are implemented, a reference signal can be transmitted on a flexible frequency band, thereby effectively reducing interference between reference signals between neighboring cells in a flexible duplex system.
