First Claim
1. A method of providing pages to subscriber stations over a wireless network within a transmission region, and near sector boundaries using a multi-sector broadcast channel, comprising:
- receiving data related to a list of all pages to be transmitted to subscriber stations in a paging region that has a plurality of sectors;
generating a substantially identical waveform at a base station in each of the plurality of sectors;
transmitting the substantially identical waveform concurrently from a subset of the sectors in the region to permit signal aggregation of waveforms over the air to page subscriber stations identified in the list of pages to be transmitted;
providing an aggregate waveform to one or more subscriber stations,wherein the aggregate waveform comprises combined signal energy from at least two substantially identical waveform transmissions from at least two different sectors to improve spectral efficiency within the transmission region and near sector boundaries; and
further comprising providing time slots synchronized across all sectors in the paging region during which individuals sectors in the region simultaneously transmit the substantially identical waveform.

Abstract
Systems and methods are described that facilitate improving paging signal strength at or near sector perimeters in a wireless network region by transmitted identical paging waveforms simultaneously from all sectors in the region and permitting over-the-air signal aggregation to combine signal energy near sector perimeters. Waveforms can be modulated using an orthogonal frequency division multiplexing technique and can be simultaneously transmitted according to predefined transmission resources over a multi-sector broadcast paging channel reserved for such identical waveforms. Cyclic prefix can be added to the identical waveforms to mitigate problems associated with delay spread and/or time-of-arrival differences at or near sector perimeters.
