Abstract: A communication method, and a communications apparatus. The method includes: a terminal device determines uplink information; when the uplink information is first feedback information, the terminal device determines a first uplink control channel resource corresponding to the first feedback information, and sends the first feedback information on the first uplink control channel resource; or when the uplink information includes A-CSI, the terminal device determines a second uplink control channel resource corresponding to the uplink information, and sends the uplink information on the second uplink control channel resource, where the first uplink control channel resource is different from the second uplink control channel resource. Therefore, a network device identifies, according to the control channel resource for the received uplink information, whether the uplink information includes the A-CSI, so that the uplink information can be correctly received without times of blind detection, and receiving complexity is low.

Abstract: Embodiments of this application provide a channel listening method and apparatus. The method includes: receiving, by a terminal, uplink grant information sent by a base station; determining a first uplink reference resource and a second uplink reference resource based on the uplink grant information; determining a contention window size based on the first uplink reference resource and the second uplink reference resource; and listening to a channel based on the contention window size. According to this technical solution, a real-time channel state can be accurately reflected, so that a probability of a collision between nodes can be reduced, and a channel access opportunity is increased.

Abstract: Example communication methods and apparatus are described. One example method includes performing first listen before talk (LBT) and sending a first data packet on a first uplink burst after the first LBT succeeds. A second contention window size is determined based on the first contention window size and a first reference time unit. Second LBT is performed based on the second contention window size. The first contention window size is used for a LBT previous to the second LBT, the first reference time unit is later than the second reference time unit corresponding to the first uplink burst. The first reference time unit is a time unit for determining the second contention window size, or a starting time unit of a second uplink burst corresponding to the second LBT. The second reference time unit corresponding to the first uplink burst is a time unit in the first uplink burst.

Abstract: Example uplink channel listening methods and apparatus are described. In one example method, a contention window size (CWS) is determined with reference to a time threshold, for example, a timer. After sending an uplink burst, if a terminal device does not receive indication information carrying a hybrid automatic repeat request (HARQ) status, the terminal device increases the CWS and then performs channel listening.

Abstract: This application describes a positioning method, apparatus, and system. The positioning apparatus includes an antenna selection circuit, a receiving processing circuit, and a processor, and the antenna selection circuit is coupled to the processor through the receiving processing circuit. The antenna selection circuit is coupled to an antenna array that includes M*N antenna elements, and the antenna selection circuit selects different combinations of antenna elements from the antenna array, where each combination of antenna elements includes L antenna elements. The processor controls the antenna selection circuit to select a combination of antenna elements from the antenna array. The receiving processing circuit receives an answer signal from a tag through L antenna elements selected by the antenna selection circuit, and processes the answer signal. The processor then positions the tag based on processed data.
