Abstract: Aspects relate to techniques for exchanging resource pool (RP) configurations between wireless communication devices. A transmitting wireless communication device can transmit a remaining minimum system information (RMSI) message including a RP configuration of the transmitting wireless communication device to at least one receiving wireless communication device. The RMSI message is transmitted within a minimum resource block set that is common to both the transmitting wireless communication device and the at least one receiving wireless communication device. The transmitting wireless communication device may then communicate with the at least one receiving wireless communication device on a sidelink based on the RP configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that that the first UE is scheduled to transmit a control signal and a synchronization signal associated with a synchronization signal block. The first UE may transmit, to a second UE during a first set of symbols within a time period, the control signal associated with a sidelink communication. In some examples, the first UE may transmit, to the second UE during a symbol subsequent to the first set of symbols, the synchronization signal associated with the synchronization signal block, and may communicate with the second UE according to the transmitted control signal and the transmitted synchronization signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a helper user equipment (UE) may receive, from a base station, a signaling message requesting the helper UE to monitor for and transmit a sidelink communication in a manner that uses a single-frequency network, wherein the sidelink communication is to be transmitted by a source UE to a destination UE that is different from the helper UE. The helper UE may receive the sidelink communication, transmitted by the source UE to the destination UE, in a first time-frequency resource of the single-frequency network. The helper UE may transmit the sidelink communication in a second time-frequency resource of the single-frequency network, wherein the second time-frequency resource is indicated to the helper UE by the base station. Numerous other aspects are described.
