Air interface protocols for a radio access network with ad-hoc extensions

摘要

To reduce the overhead induced by transmitting data between a mobile client ( 1 ) and a cellular network ( 4 ) via an ad-hoc network ( 2 ) extension it is suggested, that the cellular network ( 4 ) transmits data dedicated to the mobile relay ( 3 ) and dedicated to the mobile client ( 1 ) within the same data stream; the mobile relay ( 3 ) detects whether data received by the mobile relay ( 3 ) contains data that are dedicated to the mobile relay ( 3 ) itself and terminates the part of the received data that is dedicated to the mobile relay ( 3 ) itself; the mobile relay ( 3 ) detects whether data received by the mobile relay ( 3 ) contains data that are dedicated to the mobile client ( 1 ) and forwards the part that is dedicated to the mobile client ( 1 ) to the mobile client ( 1 ); and the mobile relay ( 3 ) detects whether data received by the mobile relay ( 3 ) contains data that are dedicated to the cellular network ( 4 ) and forwards the part that is dedicated to the cellular network ( 4 ) to the cellular network ( 4 ).
