| Abstract: |
We consider the uplink and the downlink of a multiuser wireless system with one base station and K user terminals. Each user is affected by a position-dependent path loss, fixed in time, and by a slowly time-varying frequency-selective fading channel modeled as M parallel block-fading channels. We study ``delay-limited'' systems (each user transmit at its desired rate irrespectively of the channel conditions) and ``delay-tolerant'' systems based on the Proportional-Fair Scheduling (PFS) algorithm. Our analysis allows us to quantify the effect of imposing ``hard-fairness'' (the delay-limited setting) versus ``proportional-fairness'' (the dealy-tolerant setting) in a cellular environment, for given M, K and channel statistics. |
