Abstract: An uplink channel sending method includes sending, by a terminal device, a first uplink channel to a network device at a first power in a first time unit of a first Bandwidth Part (BWP) region, and sending, by the terminal device, the first uplink channel to the network device at a second power in a second time unit of a second BWP region. The second time unit is adjacent to the first time unit, the second BWP region is different from the first BWP region, and the second power is determined using a reset accumulated closed-loop power, an absolute closed-loop power, or the first power and an offset value.

Abstract: This application provides a signal processing method and apparatus. A network device obtains capability information of a terminal device, where the capability information includes a processing time period for uplink data of the terminal device and a processing time period for uplink control information of the terminal device; determines a first time-frequency resource based on the capability information, where the first time-frequency resource is used to carry first uplink data and/or first uplink control information; and sends first signaling to the terminal device, where the first signaling indicates the first time-frequency resource. This application can improve efficiency of configuring a time-frequency resource by the network device for the first uplink data and/or the first uplink control information of the terminal device, thereby reducing a signal transmission delay.

Abstract: This application discloses a data receiving method, which may be applied to Internet of Vehicles, for example, V2X, LTE-V, and V2V. A first terminal apparatus may receive first control information from a second terminal apparatus, then receive second control information from the second terminal apparatus based on the first control information, and further receive, based on the first control information and the second control information, data sent by the second terminal apparatus. Therefore, the second control information and the data can be received after blind detection is performed on the first control information for a relatively small quantity of times, thereby improving efficiency of receiving the second control information and the data.
