摘要
Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may select, from a plurality of short transmission time intervals (TTIs), a short TTI for a vehicle-to-vehicle (V2V) sidelink transmission by the UE. The short TTIs may occur within a legacy TTI. The short TTIs may be allocated for V2V sidelink transmissions by non-legacy UEs. The legacy TTI may be allocated for V2V sidelink transmissions by legacy UEs. The UE may transmit, in accordance with the legacy TTI, a legacy physical sidelink control channel (PSCCH) to indicate, to legacy UEs, the V2V sidelink transmission by the UE. The UE may transmit, in accordance with the selected short TTI, a short PSCCH (sPSCCH) to indicate, to non-legacy UEs, the V2V sidelink transmission by the UE.
