In this paper we propose a two-step distributed scheduling algorithm for relay-assisted cellular networks where a given user can be either served by the base station or by a relay, in a opportunistic way. Such a distributed approach allows a reduced feedback signaling with respect to the centralized case, especially when a simple scalar feedback is not sufficient for estimating the channel quality...
Cooperation between adjacent base stations (BSs) may reduce intercell interference in future cellular networks and enhance network capacity in this way. The potential of cooperation is evaluated in this paper based on measurements conducted at 5.2 GHz in a campus environment with four overlapping cells. For each individual link of the four BS and five terminal locations, a 10 times 16 antenna configuration...
Cellular CDMA systems have to trade user capacity to increase cell coverage. Moreover, coverage of CDMA is uplink-limited because uplink channels are not orthogonal and transmit powers of mobile stations are limited. In this paper, we propose a coverage-dependent dynamic channel allocation (DCA) method for TDMA-CDMA. In this method, different uplink timeslots have different level of coverage-capacity...
