    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.
