SEMI-PERSISTENT SCHEDULING (SPS) FOR SIDELINK GROUPCAST

Abstract:

Systems and methods for implementing semi-persistent scheduling (SPS) transmission of periodic messages via one or more sidelinks are described. SPS for a sidelink groupcast may be activated and/or deactivated using SPS control signaling for the sidelink groupcast. SPS control signaling utilized for activating/deactivating SPS for a sidelink groupcast may include a SPS indicator (e.g., conveyed at least in part via SCI format 0-1 message), an activation/deactivation indicator (e.g., conveyed at least in part via SCI format 0-1 message and/or SCI format 0-2 message), and/or a configuration index (e.g., conveyed at least in part via SCI format 0-1 message and/or SCI format 0-2 message). Other aspects and features are also claimed and described.
