Abstract
A low data rate wireless channel (control channel) is associated with a high speed wireless channel (data channel). The data channel is divided into discrete code or time slots (access slots), that are unassigned to any particular recipient or user until requested. In the event that a particular user requires a particular resource, access slots are requested through the control channel, allocated to the user, and allocation information is passed back to the requesting user through the control channel. Direction and/or location information associated with the user is ascertained, through messaging with the user or by antenna sensing. This direction/location information is utilized to directionally broadcast requested resources toward the user to increase signal to noise ratios, reduce interference, and enable spectrum reuse within a cell. Optionally, the location information may also be used to adjust the transmitted power to further reduce interference in the cellular network.
