    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to transmit positioning reference signals (PRSs) to a second UE in an unshared radio frequency spectrum and transmit supplemental PRSs to the second UE in a shared spectrum. The second UE may then use the supplemental PRSs in addition to the PRSs in the unshared spectrum to compute a position of the first UE. In some cases, the first UE may signal a configuration for the supplemental PRSs to the second UE, and, in other cases, a base station may signal the configuration for the supplemental PRSs to the second UE. In any case, because the second UE may use both the PRSs in the unshared spectrum and the supplemental PRSs to compute the position of the first UE, the accuracy of the computed position of the first UE may be improved.

    Abstract: Certain aspects of the present disclosure provide techniques for transmitting system information on sidelink. A method that may be performed by a first user equipment (UE) includes receiving first system information from a second UE; determining, based on one or more first parameters, to receive second system information from the second UE; receiving the second system information in a sidelink system information block (S-SIB) from the second UE; and communicating with the second UE via sidelink resources determined based on the first system information and the second system information.

    Abstract: A wireless device may identify a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic. The wireless device may identify a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic. The first subband and the second subband may be different. The wireless device may reserve the first subband for a first duration of time for a plurality of wireless devices. The reservation may be based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband.

    Abstract: Methods, systems, and devices for wireless communications are described in which multiuser superposition transmission (MUST) is used to provide multiple concurrent sidelink transmissions using a same set of time and frequency resources. A transmitting user equipment (UE) may provide an indication of concurrent MUST transmissions in sidelink control information (SCI), and a receiving UE may decode one or both of a MUST base layer communication and a MUST enhancement layer communication. The base layer communication may include broadcast or groupcast transmissions to multiple UEs, and the enhancement layer communication may include a unicast transmission between the transmitting UE and a single receiving UE. The indication of concurrent transmissions may be provided in a first stage SCI, and parameters for decoding the base layer and enhancement layer transmissions may be provided in one or multiple second stage SCI transmissions.

    Abstract: Methods, systems, and devices for wireless communications are described. The methods include determining a sidelink message to transmit to a second user equipment (UE) over a time resource of a sidelink connection between a first UE and the second UE, encoding at least a subset of time periods of the time resource according to a configuration that is based on a switching time for the second UE for switching from a receiving mode to a transmitting mode during reception of the sidelink message during at least the subset of time periods of the time resource, and transmitting the sidelink message to the second UE using a set of time periods of the time resource that includes the subset of time periods.
