Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may periodically transmit one or more sidelink synchronization signals (SLSSs), which may enable other UEs to synchronize communications with the UE. A UE may apply a cyclic shift to one or more symbols of an SLSS in the time domain, which may differentiate SLSSs transmitted by different UEs and/or reduce destructive interference between SLSSs. In some examples, a receiving UE may apply one or more cyclic shift hypothesis to incoming SLSSs and perform one or more operations to evaluate an accuracy of each hypothesis. In some examples, a receiving UE may perform an autocorrelation operation to receive SLSSs (e.g., to detect the cyclic shift) or otherwise evaluate the accuracy for various cyclic shift hypothesis. A UE may determine if SLSSs are transmitted by a single UE or multiple UEs, which may improve communication reliability for SLSSs.

Abstract: Methods, systems, and devices for wireless communications are described. In polar coding, some bits channels have a higher reliability and other bit channels have a lower reliability. Data may be transmitted on some of the bit channels, and frozen values known to both the receiver and transmitter may be transmitted on the remaining bit channels. The performance of different polar code schemes (e.g., which bit channels are frozen) may depend on the decoder the receiving device uses. A receiving device (e.g., a user equipment for downlink transmissions) may indicate a decoder or polar decoding capability to the transmitting device (e.g., the network entity for downlink transmissions), and the transmitting device may select and indicate to the receiving device a polar coding scheme based on the indicated decoder or decoding capability. The transmitting device may transmit a communication to the receiving device encoded in accordance with the indicated polar coding scheme.
