Device-to-device discovery resource allocation

摘要

The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for implementing a D2D discovery resource allocation by a network for D2D discovery by UEs belonging to multiple cells in a D2D discovery area, e.g., in LTE wireless systems. A network such as LTE may determine an allocation of one or more resources (UL and/or DL) for a device-to-device discovery among a plurality of UEs located in multiple cells of the network in a D2D discovery area. The allocation of the one or more resources is then may be provided by the network to the plurality of UEs for performing, using these one or more resources, the D2D discovery between any two UEs of the plurality of UEs located in the multiple cells in the D2D discovery area.

主权项

1. A method, comprising:
allocating, by a network, at least a portion of one or more uplink resources for device-to-device discovery among a plurality of at least three user equipments located in multiple cells of the network in a device-to-device discovery area; and broadcasting, by eNBs of the multiple cells, an indication of the allocated at least portion of the one or more uplink resources to the plurality of user equipments on synchronous Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) subframes transmitted in the time synchronization by the eNBs of the multiple cells.
