Abstract

A communication device and method of operating a communication device. In case the direct channel (191) and the relay channel (192) of the radio interface of the cellular network (100) are available for transferring data: choosing between said relay channel (192) and said direct channel (191) .

Description

technical field [0001] Various embodiments relate to apparatus and methods. In particular, various embodiments relate to selecting between a direct channel and a relay channel of a radio interface of a cellular network if the direct channel and the relay channel are available for communicating data. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) radio access technology, relaying is a technique for extending the coverage of a cell of a cellular network. Here, instead of establishing a direct connection with an access node of a wireless network, a communication device (UE) connects with a relay station that wirelessly forwards or relays data to the access node of a cellular network. This situation is often referred to as cell edge extension, because the UE is able to connect to this relay station even if it is located outside the range of the access node; therefore, in this case, between the UE and the access node, the...
