Systems and Methods for Scalable Device-to-Device Discovery via Device Grouping

摘要

System and method embodiments are provided to select and organize devices in a wireless network for allowing efficient transmission of discovery signals. In an embodiment, a network controller for grouping devices for device-to-device (D2D) discovery allocates a plurality of transmission opportunities for D2D discovery in a wireless network. Each one of the transmission opportunities defines at least one of a time slot and a frequency for transmitting a discovery subframe for D2D discovery. The network controller further groups, via signaling, a plurality of devices in the wireless network into a plurality of groups, wherein the devices in each group are in close proximity to each other. The network controller then assigns a corresponding transmission opportunity of the allocated transmission opportunities to each group.

1. A method performed by a network controller for grouping devices for device-to-device (D2D) discovery, the method comprising:
allocating a plurality of transmission opportunities for D2D discovery in a wireless network, each one of the transmission opportunities defining at least one of a time slot and a frequency for transmitting a discovery subframe for D2D discovery; grouping, via signaling, a plurality of devices in the wireless network into a plurality of groups, the devices in each group of the groups being in close proximity to each other; and assigning to each group a corresponding transmission opportunity of the allocated transmission opportunities.
