Multihop techniques have been shown to provide ameans to increase coverage and/or capacity in cellular net-works. The concept is, however, challenged by a lackof forwarding incentives. Studies of a scheme called Re-source Delegation and pricing based rewards, have shownthat multihop solutions can significantly increase operatorrevenue, user data rates and service appreciation while atthe same time lowering the interference level in the net-work; compared to classical cellular architectures.Previous work has focused on the gains on a systemlevel. In this paper1 we investigate the data rate gains on aper-user level and discuss some implementational aspects.In particular we study how a silent period associated withthe relay switching from receive to transmit mode affectsmultihopping performance.It is found that the larger part of the rate improvementsis attained by users far from the base stations. This in-dicates that resource delegation both increases the aver-age data rate and reduces the distance dependent spread inrates. It is also seen that the silent receive-transmit transi-tions of relays do not severely compromise the benefits ofresource delegation in a TDMA system.
