“…As we will demonstrate in this paper, selection diversity using partial CSI increases multiuser diversity gain. Resource allocation and scheduling in multiple antenna systems have also been studied in [11] and [12]. However, the issue of fair scheduling is not properly addressed.…”

Abstract-In this paper, we study cooperation among the adjacent base stations (BSs) for downlink scheduling in code division multiple access cellular networks. We propose a cooperative fair scheduling scheme, namely, cooperative utility fair scheduling, to increase multiuser diversity gain and reduce interference among BSs. The scheduler maintains fairness and smooth service delivery by balancing the long-term average throughput of users. Monte Carlo simulation results are given to demonstrate the effectiveness of the proposed scheme in terms of multiuser diversity gain, throughput, and fairness.Index Terms-Code division multiple access (CDMA) cellular networks, cooperative communications, fair scheduling, Monte Carlo simulations.

Abstract-This paper studies different degrees of channel quality-based scheduling freedom for the downlink of a DS-CDMA system where the base station (BS) and each mobile station (MS) have 2 antennas. The system combines opportunistic user time slot scheduling, opportunistic spatial multiplexing, and adaptive modulation and coding (AMC) with limited and unlimited allowable constellation sizes. System performance is investigated in a time dispersive propagation environment, with varying degrees of antenna correlation. Three transmission schemes with increasing degrees of resource allocation freedom are identified. The full freedom scheme allows for time slots and transmit antennas to be independently allocated to different users and is compared to two schemes of more limited flexibility in the antenna allocation. For a system with little multi user diversity gain, i.e. fewer than 5 users, the option of single antenna selection transmit diversity is favorable, while dual antenna transmission with independent antenna-to-user allocation becomes increasingly important when a higher degree of multi user diversity can be exploited.
