Abstract: A method by a first UE for selecting a radio resource for transmitting a packet, includes obtaining a basic period value related to expected timing of transmissions by a second UE. A sub-period value is obtained that is less than the basic period value. Radio resources are monitored for a packet or booking message that is transmitted by the second UE and indicates that the second UE will potentially transmit a next packet using a radio resource and timing. The monitoring is restricted to a timeframe determined based on the sub-period value within each occurrence of a time period determined based on the basic period value. Responsive to the monitoring identifying the packet or booking message, a radio resource is selected for use in transmitting a packet based on the radio resource and timing that is potentially to be used by the second UE to transmit the next packet.

Abstract: A system, communication device, and method for scheduling transmissions from the communication device. The device predicts an arrival time of a next packet for transmission when a current packet arrives in a transmission buffer. The device plans a future transmission time of the next packet based on the predicted arrival time of the next packet, and books transmission resources for the planned future transmission time.

The device may then unbook the transmission resources for the planned future transmission time, book transmission resources for the re-planned future transmission time, and notify other communication devices that the unbooked transmission resources are available for use by the other communication devices.
