Abstract

A wireless terminal (26) through a radio interface (24) 1 ) communicating with a node (22) of a radio access network, said node (22) sending said wireless terminal (26 1 ) sends an indication (62), said indication (62) indicating that for another wireless terminal (26 2 ) device-to-device (D2D) communication, the wireless terminal (26 1 ) use radio resources allocated by the network or radio resources selected by the wireless terminal.

Description

[0001] This application claims priority to and the benefit of the following U.S. Provisional Patent Application, which is hereby incorporated by reference: DETECTING OUT-OF-COVERAGE TRANSITION FOR WIRELESSDEVICE-TO-DEVICE COMMUNICATIONS, filed May 1, 2014 US Provisional Patent Application 61 / 987,324. technical field [0002] The present technology relates to wireless communication, and in particular, to allocating or authorizing radio resources for wireless device-to-device (D2D) communication. Background technique [0003] When two user equipment terminals (eg, mobile communication devices) of a cellular network or other telecommunication system communicate with each other, their data paths usually go through an operator's network. Data paths through the network may include base stations and / or gateways. If the devices are in close proximity to each other, their data paths can be routed locally through the local base station. In general, communication between network node...
