Abstract: A method for stopping monitoring a physical downlink control channel. A network device sends first DCI to a terminal device on an active DL BWP. The terminal device runs a timer, where the timer is used for BWP switching. The terminal device stops, based on the first DCI, monitoring a PDCCH within a first duration, and suspends running of the timer. The terminal device continues to run the timer after the first duration. The terminal device performs DL BWP switching when the timer expires. The network device runs a timer, suspends running of the timer within a first duration, and continues to run the timer after the first duration. The network device performs DL BWP switching when the timer expires.

Abstract: This application relates to communication methods and apparatuses. One example method includes sending, by a network device, downlink control information to a terminal device. The downlink control information includes indication information. The indication information indicates one of at least one minimum applicable slot offset (minimum K0) configured for a downlink bandwidth part (BWP) of the terminal device, or the indication information indicates one of at least one minimum applicable slot offset (minimum K2) configured for an uplink BWP of the terminal device. There is a correspondence between the minimum K0 configured for the downlink BWP and the minimum K2 configured for the uplink BWP.

Abstract: A DRX control method and apparatus may flexibly control active times of different DRXs when a plurality of DRXs is configured for a terminal device. For example, a network device may send indication information to the terminal device in a first serving cell of the terminal device, to configure the terminal device to start, prolong, or end DRX active time of a second serving cell of the terminal device. The first serving cell is configured with a first DRX, and the second serving cell is configured with a second DRX. The network device sends indication information based on the first DRX.

Abstract: This application provides a communication method and apparatus. The method includes: A terminal device sends first indication information to a network device, where the first indication information indicates that a switching delay between a first bandwidth part BWP and a second BWP is first duration, where the first BWP and the second BWP are uplink BWPs or downlink BWPs used by the terminal device to send and receive data. In this application, the terminal device can indicate to the network device a specific switching delay between two BWPs in a serving cell, so that a BWP switching delay determining method is more flexible and a result is more accurate.

Abstract: This application discloses a message transmission method. User equipment may receive a power saving message from a network device, where the power saving message carries indication information of a short message, and the short message includes at least one of the following: a public warning system notification or system information modification information. Then, the user equipment obtains the short message from the power saving message. In this way, when the user equipment is in a connected state, the user equipment may obtain the short message by using the power saving message, for example, a PoSS, instead of by monitoring a paging PDCCH; and when the UE is in a sleep state, the UE is not woken up to monitor the paging PDCCH. This reduces power consumption of the user equipment in the connected state.
