Method of performing device-to-device communication between two user equipments

摘要

In a wireless communication system, a plurality of resource groups and a plurality of synchronization signals may be used to perform device-to-device communication. First monitor time associated with sending data and second monitor time associated with receiving data is determined, and each resource group is linked to a corresponding synchronization signal, a corresponding first monitor time and a corresponding second monitor time. A user equipment is configured to select a specific synchronization signal from the plurality of synchronization signals and broadcast the specific synchronization signal for claiming the corresponding resource group only after determining that the specific synchronization signal is not being transmitted by other devices at the corresponding first monitor time and the corresponding second monitor time.

1. A method of performing device-to-device (D2D) communication between a first user equipment and a second user equipment in a wireless communication system, comprising:
providing a plurality of resource groups and a plurality of synchronization signals for use in the wireless communication system; setting first monitor time associated with sending data and second monitor time associated with receiving data; linking a first resource group among the plurality of resource groups to the first monitor time, the second monitor time, and a first synchronization signal among the plurality of synchronization signals; the first user equipment determining if the first synchronization signal is being transmitted by a third user equipment of the wireless communication system at the first monitor time and at the second monitor time during a first frame; and the first user equipment claiming the first resource group by broadcasting the first synchronization signal at the first monitor time during a second frame after determining that the first synchronization signal is not being transmitted by the third user equipment at the first monitor time and at the second monitor time during the first frame, wherein the second frame occurs immediately after the first frame.
