    摘要: A first communication device is configured to communicate with a second communication device and a third communication device in a wireless communication network using beamforming. The first communication device is configured to determine a new beam from a plurality of available beams of the second communication device in response to a beam failure event. The second communication device transmits a beam failure recovery request (BFRQ) message to the third communication device. The BFRQ message contains information about the new beam determined by the first communication device. The second communication device receives from the second communication device a BFRQ response message.

    摘要: 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.

    摘要: A power control method includes obtaining, by a first terminal, parameter information required for power control, where the parameter information includes at least one of a first parameter, a second parameter, and a third parameter, and determining, by the first terminal based on the parameter information, uplink transmit power used when uplink transmission is performed on a target beam or a target beam pair; where the first parameter includes a beam reception gain of a network device and/or a beam sending gain of the first terminal, where the second parameter is used to indicate interference caused by a second terminal to the first terminal on the target beam, and where the third parameter includes beam-specific target power and/or terminal-specific target power.
