Monitoring periods for device-to-device synchronization signals

摘要

Methods, systems, and devices are described for determining a monitoring schedule for device-to-device (D2D) synchronization signals. A synchronization cycle may be determined that includes a plurality of monitoring periods. The monitoring periods may be a time between at least two start times of sequential D2D synchronization signals to detect at least one of the D2D synchronization signals. Sub-monitoring periods may be determined based on the duration of the monitoring periods. The sub-monitoring periods may have a cumulative duration the same as the duration of the monitoring period and be scheduled to occur during different monitoring periods of the synchronization cycle.

1. A method for wireless communications, comprising:
determining a synchronization cycle that comprises one or more device-to-device (D2D) synchronization signals transmitted on a periodic schedule from a D2D source; determining a monitoring period based at least in part on a start time for at least two sequential transmissions of the D2D synchronization signals occurring during the synchronization cycle based at least in part on the periodic schedule, wherein a duration of the synchronization cycle comprises a plurality of monitoring periods; determining, based at least in part on a duration of the monitoring period, a plurality of sub-monitoring periods, wherein a cumulative duration of the plurality of sub-monitoring periods is the same as the duration of the monitoring period; and monitoring, based at least in part on the plurality of sub-monitoring periods, for at least one of the one or more D2D synchronization signals.
