Abstract
Methods, systems, and devices for wireless communications are described to support resource block (RB) grid alignment at user equipments (UE) in sidelink communications. In a first example, communicating UEs may support different RB grids and a receiving UE may attempt multiple decoding hypotheses for receiving a sidelink control channel from a transmitting UE, where each hypothesis may correspond to a different RB grid. In a second example, an RB grid for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the sidelink control channel using the common RB grid. In a third example, demodulation reference signals (DMRSs) and resource element (RE) rate matching for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the control channel using the aligned DMRSs.
