Abstract: A communications method and apparatus are provided. A network device determines whether a first capability of a terminal device is less than or equal to a second capability of the terminal device. The first capability is a capability of the terminal device of working at a first frequency when the terminal device supports only a first radio access technology, and the second capability is a capability of the terminal device corresponding to the first frequency in a first frequency combination. When the first capability is less than or equal to the second capability, the network device sends a first message to the terminal device. The first message is used to indicate the terminal device to measure a second frequency, the first message does not include a configuration of a first measurement gap, and the first measurement gap is used to measure the second frequency.

Abstract: A bandwidth part processing method includes receiving, by a terminal, a first information and a second information from a network device. The first information indicates that at least one default bandwidth part (BWP) corresponds to at least two active BWPs, the second information indicates that the at least two active BWPs correspond to at least one first timer, and the at least one first timer is useable by the terminal to perform deactivation processing on at least one of the at least two active BWPs. The method further includes performing, by the terminal, deactivation processing on the at least one of the at least two active BWPs, and activation processing on a BWP in the at least one default BWP based on the first and second information, or performing deactivation processing on the at least one of the at least two active BWPs based on the first and second information.

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.

Abstract: A data processing method includes communicating, by a remote terminal device, with a network device by a relay device. The communicating includes starting a timer in response to a radio resource control (RRC) connection establishment procedure of the remote terminal device being initialized. The communicating includes sending indication information to the relay terminal device in response to the timer expiring. The indication information is useable to indicate the relay terminal device not to forward data corresponding to the remote terminal device, the indication information is useable to release a unicast link between the remote terminal device and the relay terminal device, or the indication information is useable to indicate to clear a buffer corresponding to the remote terminal device.
