In a wireless communication network having remote receivers (subscriber units) communicating through base units in a service area, each of the base units servicing a cell area encompasses one or more identifiable zones which can be occupied by receivers. According to the invention, at least one measure of the spatial size of the cell is reported to a receiver communicating with a base station, for use in location specific applications. The measure can be a size category, an average diameter or another measure, such as a shape and orientation of the cell, a boundary apex, and a boundary line of the cell. The base station coordinates are conventionally available to the receiver. By providing a measure of size, the receiver can resolve its zone or location to a coarse or low level of resolution.

Reporting the cell size and location is sufficient to facilitate some location applications in the receiver, and can reduce or eliminate reliance on satellite and other positioning systems, particularly if the zone initially defined as the cell size is resolved further, for example using time-of-arrival, power level, angular bearing and similar techniques.
