 channel (SL-DCH), which is a fixed size, predefined format periodic broadcast transmission. There is support for both UE autonomous resource selection and scheduled resource allocation by the eNodeB. Sidelink shared channel (SL-SCH) for broadcast transmission. There is support for both UE autonomous resource selection and scheduled resource allocation by the eNodeB. Sidelink broadcast channel (SL-BCH), which is a predefined transport format. ProSe Direct Discovery is the procedure by the UE to discover other UEs in its prox- limity, using LTE direct radio signals via PC5. Direct Discovery has two models: Model A involves one UE announcing "I am here." Model B involves one UE asking "who is there" and/or "are you there." There are two types of Direct Discovery: open and restricted. Open discovery does not need explicit permission from the UE being discovered. Restricted discovery requires explicit permission from the UE that is being discovered. D2D communication has two modes: Mode 1: The eNodeB schedules the exact resources used by a UE to transmit direct data and direct control information. Downlink Control Information (DCI) format 5, which has the same size as the existing DCI format 0, is used for allocating D2D Data and Physical Sidelink Control CHannel (PSCCH), carrying the Sidelink Control Infor- mation (SCI). Mode 2 A UE on its own selects resources from resource pools for the transmission of direct data (PSSCH) and direct control channel (PSCCH). The time-frequency resources where control and data can be transmitted are referred to as resource pools. All communication pools (Mode 1 and Mode 2) are defined in terms of a Sidelink control period (40, 80, 160, 320 ms) and a bitmap defining the sub- frames used for the transmission of control information. Mode 2 pools have in addition a bitmap defining the subframes for data communication. In addition, there are several other parameters defined for a resource pool like physical resource block (PRB) pairs, offsets, and some transmission parameters. Present-da
