Abstract
Techniques are described herein to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in interference between the scheduled traffic and the priority traffic communicated without first scheduling the specific communication resources. To mitigate interference between different traffic types, a user equipment (UE) may transmit a device-to-device silencing message to other UEs. Upon receiving the silencing message, the other UEs may release any scheduled communication resources that at least partially overlap with the semi-persistent resources.
