Abstract: The embodiments of this application provide a method and a device for sending and receiving control information, to flexibly adjust reliability of uplink transmission. A network device sends indication information of an uplink control channel to a terminal device. The indication information of the uplink control channel indicates at least one parameter of the following transmission parameters: a time domain length, a frequency domain length, a time domain repeat count, a frequency domain repeat count, or a transmit diversity manner. The network device receives uplink control information from the terminal device according to the indication information by using the uplink control channel.

Abstract: Embodiments of the present invention provide a power allocation method and a communications device. The power allocation method includes: determining, by a first communications device, a first power control parameter group, where the first power control parameter group includes information used to indicate a transmit power of the first communications device in a first-type subframe, and sending, by the first communications device, a signal only on a downlink frequency resource in the first-type subframe; and determining, by the first communications device, a second power control parameter group, where the second power control parameter group includes information used to indicate a transmit power of the first communications device in a second-type subframe, and sending, by the first communications device, signals on both a downlink frequency resource and an uplink frequency resource in the second-type subframe.

Abstract: 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.

Abstract: Embodiments of the present invention disclose an interference suppression method and a related device and system. The method includes: sending, on a specified time-frequency resource, a first reference signal or a first reference signal group to an interfered-with end; receiving interfering source information sent by the interfered-with end, where the interfering source information includes an interference identifier used for indicating whether a potential interfering source causes interference to the interfered-with end; and if the interference identifier in the interfering source information indicates that the potential interfering source sending the reference signal on the specified time-frequency resource causes interference to the interfered-with end, determining that the potential interfering source is an interfering source, otherwise, determining that the potential interfering source is a non-interfering source. According to the present invention, mutual interference between uplink and downlink signals of terminals located in a same cell or different cells can be suppressed.
