Title: DEVICE-TO-DEVICE TRANSMISSION IN COMMUNICATIONS
Abstract:
A method for providing an ad-hoc network provided, wherein at least one group of mobile devices (102, 103, 104) operate as a device-to-device cluster having a currently elected cluster head device (102). The method comprises configuring, in a network apparatus (101, 102) for the device-to-device cluster, a cluster-specific cell-level radio network temporary identifier C-RNTI on the basis of a content-sharing service requested within the device-to-device cluster. C-RNTI is used to act as a cluster-specific virtual radio access user responsible for transmission between a serving base station (101) and the currently elected cluster head device (102) on behalf of the device-to-device cluster.
