Base station cooperation BSC has been identified as a key radio access technology for next-generation cellular networks such as LTE-Advanced. BSC impacts cell planning which is the methodical selection of base station BS sites and BS equipment configuration for cost-effective cellular networks. In this paper the impact of BSC on cell plan parameters coverage traffic handover and cost as well as additional cell planning steps required for BSC are discussed. Results show that BSC maximizes its gains over noncooperation NC in a network wherein interference from cooperating BSs is the main limitation. Locations exist where NC may produce higher throughputs therefore dynamic or semistatic switching between BSC and NC called fractional BSC is recommended. Because of interference from noncooperating BSs the gains of BSC over NC are upper bounded and diminishes at greater intersite distances because of noise. This encourages smaller cell sizes higher transmit powers and dynamic .
