  • Patent number: 11985576
    Abstract: For sidelink vehicle-to-everything (V2X) transmission, a first user equipment (UE) obtains time-and-frequency resources that are bounded by two subchannel boundaries and two slot boundaries. The first UE transmits encoded control information to a second UE in a Physical Sidelink Control Channel (PSCCH) that occupies a first portion of the time-and-frequency resources starting from a lowest resource block (RB) in a lowest subchannel and from an earliest symbol available for sidelink control and data transmission. The first UE further transmits encoded data to the second UE in a Physical Sidelink Shared Channel (PSSCH) that occupies a second portion of the time-frequency resources. The second portion includes (a) a first set of RBs in the same symbols as the PSCCH and not used by the PSCCH, and (b) a second set of RBs in symbols not used by the PSCCH.
