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: When cell system information changes, a first terminal device receives, during on duration of the first terminal device, system information sent by a second terminal device, so that the first terminal device can receive the system information through a sidelink between the first terminal device and the second terminal device without a need to maintain a cellular link, thereby reducing complexity and power consumption of system information transmission. Alternatively, when cell system information changes and a first terminal device has only one receive radio frequency chain, the first terminal device obtains system information within a gap period of communication between the second terminal device and the first terminal device through a link between the first terminal device and a network device, so that the first terminal device maintains a cellular link only within the gap period, thereby reducing complexity and power consumption of system information transmission to some extent.

Abstract: A communication method includes receiving a paging message, wherein the paging message comprises a first identifier. The first identifier is useable to identify a paged first terminal device. A bit length of the first identifier is less than a bit length of a second identifier. The second identifier is a 5th generation-system-temporary subscriber identity (5G-S-TMSI) or a radio network temporary identity (I-RNTI). The communication method further includes determining, based on the first identifier, that the first terminal device is paged.

Abstract: This application provides example information transmission methods and example apparatuses. One example method includes receiving, by a first network device, an overheating message sent by a terminal device, where the overheating message includes overheating assistance information, and where the overheating assistance information is used to indicate whether the terminal device is overheated. The first network device can then determine a second message based on the overheating assistance information, where the second message is used to indicate a second network device to adjust a communications parameter configured for the terminal device The first network device can then send the second message to the second network device.
