The study of cooperative wireless communication is a more recent activity that started in the late 1990s, and since then has seen explosive growth in many directions. Our focus is specifically on aspects of cooperative communication related to cellular radio. Aside from the fading model, the defining aspects of a cellular system are base stations that are connected to an infrastructure known as the backhaul, which has a much higher capacity and better reliability than the wireless links. The endpoints of the system are mobiles that operate subject to energy constraints (battery) as well as constraints driven by the physical size of the device that lead to bounds on computational complexity and the number of antennas, among other considerations.

Somekh et al. [3] used the circular Wyner cellular model [4] to find expressions for downlink (and uplink) capacities with base station cooperation, which is also sometimes called multicell processing. In [5] the same model and a zero-forcing beamforming approach were used for data transmission in multiple cells. In particular, the approach is to transmit to the best user in each cell, and the high-load asymptotics are derived in an information theoretic approach. Mundarath et al. [6] considered the scheduling aspects of distributed downlink zero-forcing beamformers under finite loads.

Any unaccounted for delay, or delay variation anywhere within the transmit or receive path, would cause transmitted signals to arrive at the mobile station unaligned, causing loss in beamforming gain. These are requirements that often do not appear in theoretical studies, but in fact play an important role in any practical implementation. To summarize, base station cooperation offers the opportunity for improvent in two opposing directions: incorporating more theoretical results and addressing practical issues.
