Abstract: This application relates to terminal devices, and discloses a method. In the method, a battery protection voltage parameter is determined based on battery usage data, where the battery protection voltage parameter is used to change an original voltage parameter corresponding to a battery level; a second mapping relationship between an actual battery level and a target battery level is determined based on the battery protection voltage parameter; and the target battery level is determined based on the second mapping relationship and the actual battery level of the battery. Alternatively, a correspondence between an actual battery voltage and a target battery level is determined based on the battery protection voltage parameter; and the target battery level is determined based on the correspondence and the actual battery voltage of the battery.

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: 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.
