Abstract: A communication method and device for reducing power consumption of receive user equipment (RX UE) are provided. The method includes: when there is no reserved resource used to retransmit first transmission on a sidelink, a first communication device and/or a second communication device starts a first timer, and/or stops a second timer; or when there is a reserved resource used to retransmit first transmission on a sidelink, a first communication device and a second communication device stop a second timer. In this way, the first communication device and the second communication device can jointly control, by using the first timer and the second timer, the first communication device to receive data on the sidelink, so that the first communication device may not keep monitoring SCI that is associated with a HARQ process corresponding to the first transmission.

Abstract: This application provides example bandwidth part (BWP) adjustment methods and apparatuses. One example method includes receiving, in a first BWP, first indication information sent by a network side device, where the first indication information indicates information about a second BWP to be used by a terminal device to receive or send data. The terminal device can then receive or send the data in the second BWP.

Abstract: A communication method, including: A terminal device receives a master information block MIB, where the MIB includes first indication information and second indication information, the first indication information indicates whether a cell is barred, and the second indication information indicates whether an intra-frequency reselection operation is allowed. When the first indication information indicates that the cell is barred, the terminal device determines, based on the second indication information, whether to perform the intra-frequency reselection operation. The terminal device is reduced capability user equipment RedCap UE. Based on this technical solution, the RedCap UE can use different IFRIs when the cell is barred, to improve efficiency of the terminal device to determine to perform a cell reselection operation.
