Abstract
Official abstract text for this publication.
Embodiments of a method and system for supporting co-existence of first and second cellular networks in adjacent channels in the same geographical area are provided. The method and system synchronize the two cellular networks such that their respective uplink transmissions are aligned in time and their respective downlink transmissions are aligned in time. Such synchronization prevents (or substantially prevents) the uplink transmissions from one of the two cellular networks from overlapping with the downlink transmissions of the other cellular network, and vice versa, thereby mitigating interference between the two networks.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for supporting co-existence of first and second cellular networks in adjacent channels, the first cellular network communicating a first frame of data and the second cellular network communicating a second frame of data, the method comprising: shifting communication of an uplink portion of the first frame relative to communication of the second frame by a first time to mitigate transmission of the uplink portion of the first frame during transmissio…
