摘要： A method for determining a slot format and a device are disclosed, to determine an ECP slot format. The method for determining a slot format includes: obtaining first indication information, where the first indication information includes indication information of a slot format a, the slot format a is one of slot formats of a first-type slot, the first-type slot includes N symbols, and N is 14; and determining a slot format b of 2(μ-μa) consecutive second-type slots based on a subcarrier spacing μa applicable to the first indication information, a subcarrier spacing μ applicable to the second-type slot, and the indication information of the slot format a, where the second-type slot includes M symbols, and N is not equal to M.

摘要： A distributed system is run in a device in the method. The distributed system includes a system service, a first-type service located at an upper layer of the system service, and a second-type service located at an upper layer of the first-type service and having an interface display function. Both the first-type service and the second-type service are atomic services. A second device migrates a teaching video to a first device, and the first device plays the teaching video. A second-type service in the first device may call a first-type service in another device, to control the another device to capture a user action picture video, process the teaching video and the user action picture video to obtain teaching guidance, and play the teaching guidance.

摘要： This application provides a wireless communication method 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.

摘要： An uplink power control method and a communications device are described. The method includes receiving, by a terminal device, power control indication information sent by a network device. The power control indication information indicates a first power offset set, and the first power offset set is any one of at least two power offset sets. The method further includes receiving, by the terminal device, a transmit power control (TPC) command sent by the network device. The TPC indicates a first offset in the first power offset set. The method includes determining, by the terminal device, uplink transmit power based on the first offset. Impact of cross interference is considered in determining the uplink transmit power. Thus, the method can meet requirements of future mobile communications and improve system performance.

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.
