Measuring Neighboring Cell Loading in Wireless Communications

Abstract

Systems and methodologies are described that facilitate detecting cell interference and/or loading by analyzing control data transmitted between devices communicating in the cell. Control data resources can be transmitted related to communication received over data channels, and the control data resources can comprise quality indicators related to the data as well as resource identifiers that specify a resource over the data channel related to the data. Multiple control data resources can be transmitted per communication specifying a beginning and ending resource identifier of related data channel resources. If this control data is decodable at a wireless device, the associated resources corresponding to the resource identifiers can be marked as interfered and/or avoided in subsequent communication or resource allocation requests by the wireless device.
