Multicell Processing (MCP) techniques have attracted considerable research attention since they can effectively mitigate Other-Cell Interference (OCI). However, the potential gain of MCP comes with several practical challenges including huge overhead and stringent synchronization requirements. In this paper, the authors propose cooperative opportunistic scheduling to coordinate OCI for downlink transmission in multiple antenna cellular networks, which incurs less overhead and relaxes synchronization requirements. As a baseline for comparison, they study the average throughput with noncooperative opportunistic scheduling and derive the throughput expression in closed form.
