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.

Abstract: Embodiments of the application provide a sidelink logical channel multiplexing method and apparatus. After determining a first sidelink logical channel (SL LCH) that meets a first preset condition in at least one SL LCH, a terminal allocates a resource to data of the first SL LCH. Then, when a remaining resource of transmission resources is more than zero, the terminal determines, according to a communication range of the first SL LCH, a second SL LCH that meets a second preset condition, and allocates a resource to data of the second SL LCH. The first SL LCH and the second SL LCH are different. In the method, such a parameter as a communication range is considered in a multiplexing process, and data of SL LCHs with same or different communication ranges is multiplexed into a same transport block.
