As further shown in FIG. 3, the sidelink channel 310 may include a physical sidelink control channel (PSCCH) 315 and a physical sidelink shared channel (PSSCH) 320. The PSCCH 315 may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and/or a physical uplink control channel (PUCCH) used for communications with a base station 110. The PSSCH 320 may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and/or a physical uplink shared channel (PUSCH) used for communications with a base station 110. For example, the PSCCH 315 may carry sidelink control information (SCI) 325, which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time, frequency, and/or beam resources) where a transport block (TB) 330 that includes data is carried on the PSSCH 320 and/or other control information that may be used to assist in receiving, decoding, and/or demodulating data carried via the PSSCH 320. The TB 330 may include D2D data and/or V2X data, such as a basic safety message (BSM), a traffic information message (TIM), a signal phase and time (SPAT) message, a MAP message to convey geographic road information, a cooperative awareness message (CAM), a distributed environment notification message (DENM), an in-vehicle information (IVI) message, and/or the like. In some aspects, the V2X data may include data relevant to operation of a vehicle associated with a UE 305.
