Abstract
Methods and apparatus for mitigating interference which are well suited for high density deployments of small base stations are described. In various embodiments, control channel resources are intentionally not fully utilized. A control channel resource utilization parameter is set, e.g., as a function of interference, to limit base station average transmission power used for transmitting signals on control channel resources. By controlling utilization of control channel resources, e.g., by limiting resource utilization to result in a lower than possible, e.g., permitted, average transmission power level, the base station constrains the amount of interference to other nearby devices, e.g., base stations and UE devices. Nearby base stations operate and/or are controlled in a similar manner. As a result, nearby base stations which are causing interference to one another will reduce inter-base station interference. The restriction on resource utilization in some embodiments is increased as the amount of interference between base stations increases.
