- W1644807793 abstract "We consider the problem of resource allocation in multiuser single-antenna wideband OFDM(A) systems. The key advantage of such systems with respect to narrow band systems is the possibility of considering frequency as an additional resource to be allocated. Although the maximum normalized average throughput is not increased with respect to that in a narrowband system, a more efficient use of resources is possible especially if the bandwidth is considerably larger than the coherence bandwidth of the channel and the channel is varying slowly with respect to the scheduling updates. This is mainly because randomness in the system is increased by the wideband resources. The work presented in this paper analyzes the effects of bandwidth on the delay characteristics. To this end, the relationship between ergodic information rates, stability and delay in multiuser communications systems is studied and candidate resource allocation policies are presented and simulated" @default.
