Abstract: This application provides an information transmission method, a network device, and a terminal device. The method includes: generating, by a network device, downlink control information DCI; determining, by the network device, a corresponding processing manner based on a format of the DCI; performing, by the network device, processing in the processing manner in an encoding process of the DCI; and sending, by the network device, the processed DCI over a physical downlink control channel PDCCH. The information transmission method provided in this application can resolve a problem of a failure in blind detection on DCI caused by a nested encoding feature of polar encoding. When a terminal device cannot determine the format of the DCI sent by the network device, the network device may use a mapping relationship, and the network device processes DCI of a format in a processing manner.

Abstract: A method for power control during service transmission includes sending, by a user equipment (UE), a first signal on a first symbol set on a first carrier using a first transmit power, and sending, by the UE, a second signal on a second symbol set on a second carrier using a second transmit power. A time resource on the first symbol set overlaps with a time resource on the second symbol set. The first transmit power is a transmit power configured by a first base station. The second transmit power is less than or equal to a transmit power configured or indicated by a second base station.

Abstract: The method is applied to a communications system including a first network device, a second network device, and a terminal device. The terminal device is communicatively connected to the first network device and the second network device respectively. The method includes: sending, by a network device, a first message to the terminal device, where the first message is used to determine that the terminal device stops communication with the first network device, or the first message is used to determine that the terminal device releases a protocol stack and a data radio bearer that are corresponding to the first network device; and the network device is the first network device or the second network device. Therefore, power consumption of the terminal device or the first network device and waste of air interface resources can be reduced, and flexibility can effectively be improved in a communication process.
