A method and apparatus for service data adaptation protocol (SDAP) configuration for a destination in sidelink communication is provided. A wireless device establishes a service data adaptation protocol (SDAP) entity based on a SDAP configuration per destination of a sidelink communication. This can be achieved by the wireless device receiving a configuration of one or more sidelink radio bearers (SLRBs), which includes an SDAP configuration for each of the one or more SLRBs. Each SDAP configuration, in turn, includes a list of Quality of Service Flow Identities (QFIs) for a corresponding destination, from among one or more destinations, to be mapped to a corresponding SLRB. One or more transmitting SDAP entities can then be established for each of the one or more destinations.
