TRANSPORT BLOCK SIZE DETERMINATION FOR SIDELINK COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support direct communications with other communications devices (e.g., direct communications between multiple UEs). Direct communications may include, but are not limited to, device-to-device (D2D) communications, vehicle-based communications, which may also be referred to as vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, and the like. In an example of V2X communications, V2V communications, and the like, a UE may identify sidelink information for sidelink communications, encode the sidelink information for the sidelink communications based on a transport block size (TBS), determine the TBS for the sidelink information based on an overhead size of a second physical sidelink channel for communicating the sidelink information, and transmit the sidelink information on a physical sidelink channel.
