Techniques for propagation delay compensation (pdc)

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for propagation delay compensation (PDC). In some systems, a network entity and a group of user equipment (UEs) may support a group-based PDC procedure according to which the network entity may provide group-based PDC information to the group of UEs. In some aspects, a UE may participate in such a group-based PDC procedure in accordance with a clock accuracy constraint of the UE and depending on whether other UEs are likely to have similar PDC information. The network entity may assign an identifier (ID) to the group of UEs and scramble a message including the group-based PDC information using the ID. As such, UEs of the group of UEs may decode the message using the ID and adjust a timing of communications with the network entity using the group-based PDC information.
