Abstract: Embodiments of this application disclose a communication method and apparatus. The method includes that a terminal device sends a first uplink signal to a first network device on at least one first carrier. The method further includes that the first network device detects the first uplink signal on the at least one first carrier, determines an active carrier based on determined signal strength of the first uplink signal on the at least one first carrier, and sends first feedback information to the terminal device. The first feedback information includes information about the active carrier in the at least one first carrier. A corresponding apparatus is further provided. In this way, the signal strength of the first uplink signal sent by the terminal device on the at least one first carrier is determined, to accurately determine the information about the active carrier in the at least one first carrier.

Abstract: Embodiments of this application relate to the field of wireless communication, and provide a sidelink control information sending method and a device. After obtaining first information, a second terminal device may send sidelink control information to a first terminal device based on the first information, where the first information includes indication information indicating a type of the sidelink control information or includes characteristic information. The first terminal device may determine the type of the sidelink control information based on the first information, and further may blindly detect only a type of sidelink control information that the first terminal device needs to detect. This reduces complexity of blindly detecting the sidelink control information by the first terminal device.

Abstract: A network slice selection method, a radio access device, and a terminal, where the method includes obtaining, by a radio access network (RAN) device, network slice information, sending, by the RAN device, a first message to a terminal, where the first message includes the network slice information, receiving, by the RAN device, a first access request message from the terminal after the terminal selects, based on the network slice information, first attribute information of a first network slice to be accessed by the terminal, and selecting, by the RAN device based on the first attribute information of the first network slice, a second network slice to be accessed by the terminal. The method enables an operator to flexibly configure a network slice, and reduces a communication latency and signaling overheads in a process in which a terminal selects a network slice.

Abstract: Embodiments of the present invention provide an interference coordination method and a base station. The method includes: allocating, by a base station, a first almost blank subframe to one or more first base stations that are interfered with by the base station; sending, by the base station, a first message to one or more second base stations that interfere with the base station, where the first message includes information used to indicate the first almost blank subframe; and obtaining, by the base station, a second almost blank subframe that is allocated by the one or more second base stations to the base station, where the second almost blank subframe is different from the first almost blank subframe. Therefore, a resource collision problem in interference coordination can be eliminated, and resource utilization can be improved.
