Apparatus and Methods for Device to Device Communications
First Claim
1. A terminal device for communicating in a cellular system, wherein the terminal device comprises:
- at least one first transceiver arranged to communicate with a plurality of communication units; and
at least one first signal processor, operably coupled to the at least one first transceiver and arranged to;
communicate with a first communication unit in the cellular system in a first mode of operation when the terminal device is located within a coverage range of at least one base station; and
facilitate in a second mode of operation direct communications between at least one other terminal device and the first communication unit when the at least one other terminal device is located outside of the coverage range of the at least one base station.

Abstract
A terminal device for communicating in a cellular system is described. The terminal device comprises: at least one first transceiver arranged to communicate with a plurality of communication units; and at least one first signal processor, operably coupled to the at least one first transceiver and arranged to: communicate with a first communication unit in the cellular system in a first mode of operation when the terminal device is located within a coverage range of the at least one base station; and facilitate in a second mode of operation direct communications between at least one other terminal device and the first communication unit when the at least one other terminal device is located outside of the coverage range of the at least one base station.
