“…This is in accordance with the philosophy driving the design of realistic communications systems that can sustain higher rates on the downlink than on the uplink -that users have a greater demand for downlink capacity than for uplink. For example, under full buffer assumptions and using dual receive antennas, cdma1xEVDO Rev A systems have sector capacity of 1500kb/s on the downlink, but only 500kb/s on the uplink [18]. Similarly, asymmetric DSL (ADSL) systems are designed to support up to 6.1 Mbps on the downstream channel, but only up to 832 kbps on the duplex channel [19].…”

Abstract-In this paper, we consider joint uplink and downlink rate allocations over a multi-access/broadcast channel pair in a single-cell system. We assume a network of heterogeneous users, where the uplink utility of each user is held as private information and is unknown to the base station. The challenge is to design an optimal rate allocation scheme in the presence of such incomplete information when considering strategic users. Here, we provide an incentive-compatible mechanism that leverages downlink demand to ensure that users truthfully reveal their uplink utilities, enabling the socially optimal uplink rate allocation. In addition, we give numerical results on a kind of efficiency of downlink allocations for two specific uplink multiaccess channels: information theoretic AWGN MAC channel, and CDMA-based uplink.

“…CDMA2000 1xEVDO Revision A (TIA-856-A) was therefore standardized in March 2004 by 3GPP2 and TIA. It meets downlink intensive applications by introducing several new concepts as H-ARQ in reverse link, higher modulation, reverse resource control, Seamless virtual soft handoff and rapid connection as depicted in [3]. With the advent of these new concepts and technologies the peak rates increases up to 3.1Mbps in downlink and 1.8Mbps in reverse link for CDMA 2000 Revision A.…”

The problem of bandwidth estimation has been extensively studied in the wired Internet and recently, in 802.11 wireless networks, however, no tool has been developed so far for cellular networks. Although cellular networks share many common characteristics with 802.11 WLANs, they also have many differences which make it unclear whether tools developed for 802.11 WLANs can also be used in cellular networks. This paper presents the first study of the feasibility of fast bandwidth estimation in 3G networks. We study the applicability of a state-of-the-art probe-based tool for 802.11 WLANs on a commercial 1x EVDO network. We find that estimating bandwidth with a probe-based tool is very difficult in EVDO networks, due to the short-scale dynamics in this type of networks.
