1. A method performed by a first device in a wireless communication system, the method comprising:
establishing multiple direct links with a plurality of devices, wherein each of the multiple direct links is established with a corresponding device;
allocating multiple link identifiers to the multiple direct links, wherein each of the multiple link identifiers is allocated to a corresponding direct link and a corresponding device, and is related to one or more destinations;
selecting a link identifier having a highest priority among the multiple link identifiers based on a priority of each of the multiple link identifiers;
selecting a destination having a logical channel with a highest priority among one or more destinations related to the selected link identifier;
allocating resources to one or more logical channels among logical channels belonging to the selected link identifier and the selected destination, in decreasing order of priority of the logical channels;
generating a data unit from the one or more logical channels;
transmitting, to a second device to which the selected link identifier is allocated, control information scheduling the data unit; and
transmitting, to the second device, the data unit,
wherein the control information comprises a first part of the selected link identifier, and
wherein the data unit comprises a second part of the selected link identifier.
