摘要： This application provides a power control method and a communications apparatus. The method includes: obtaining, by a terminal device, slot format information SFI of a target slot in a non-serving cell; and determining, by the terminal device based on the SFI, a power control parameter set used by the terminal device to send data in the target slot in a serving cell, where the power control parameter set belongs to a set of power control parameter sets configured for the terminal device. According to the power control method provided in this application, when a time domain resource conflict exists between the serving cell and the non-serving cell of the terminal device, the terminal device may determine an uplink power control parameter set of the serving cell of the terminal device by using the obtained SFI that dynamically changes in the non-serving cell. This helps reduce inter-cell cross interference and improve a system throughput, improve a rate for ensuring normal communication of a user, and improve user experience.

摘要： Embodiments of this application provide a communication processing method. A time domain location of a time domain resource configuration that is in a first wireless communications system and that is aligned with a time domain resource configuration in a second wireless communications system is determined based on a time offset, and a terminal performs data transmission with the first wireless communications system at the determined time domain location. In this way, interference with the second communications system is avoided.

摘要： This application provides a wireless communication method and an apparatus. The method may be performed by a terminal or a chip of the terminal, and the method includes: receiving higher layer signaling from a base station, where the higher layer signaling is used to configure a first time resource and a first frequency resource that can be used for uplink transmission without scheduling; and receiving downlink control information indicating a format of a slot, where the format indicates a transmission direction of a symbol in the slot, and an uplink symbol in the slot is a time resource that can be used for the uplink transmission without scheduling. In the method, a time resource that is dynamically allocated by the base station to the terminal via the downlink control information and that can be used for uplink transmission without scheduling is received. When the first time resource is unavailable or insufficient, the dynamically allocated time resource may be used to perform the uplink transmission without scheduling, to help meet a low-latency requirement and a high-reliability requirement of some services of the terminal.
