Abstract
Data transmission between a mobile client (1) and a cellular network (4) can be performed via an ad-hoc network (2) extension of the cellular network and a mobile relay (3). To reduce the overhead induced by the ad-hoc network (2) extension and still reap the benefits of extending the cellular network (4) by the ad-hoc network (2) it is suggested that a first part of the data that are transmitted from the mobile client (1) towards the cellular network (4) are transmitted directly via the air interface (8) and a second part of the data that are transmitted from the mobile client (1) towards the cellular network (4) are transmitted via the ad-hoc network (2) and the mobile relay (3). Alternatively or additionally it is suggested that a first part of the data that are transmitted from the cellular network (4) towards the mobile client (1) are transmitted directly via the air interface (8) and a second part of the data that are transmitted from the cellular network (4) towards the mobile client (1) are transmitted via the mobile relay (3) and the ad-hoc network (2).
