Spatial reuse in directional antenna systems
First Claim
Patent Images
1. A method comprising:
- determining whether to allow spatial reuse in a directional antenna system upon receipt of a request for a communication between two devices;
determining, in response to said request, whether bandwidth exists for a communication in a given time period;
providing a primary reservation in response to said request if an available channel has resources available; and
if there is no available channel time of sufficient length without communications, finding a channel with sufficient duration with only one active communication.

Abstract
In directional antennas, spatial reuse involves enabling two communications to occur on the same link at the same time. The communications may be in the same or opposite directions. If no link of sufficient bandwidth is available that does not already have an active communication, a link with an active communication of sufficient bandwidth is located. Then an antenna training sequence may be implemented. A check determines whether the antenna training sequence was successful. If there was interference during the antenna training sequence, then the spatial reuse is not permitted. Otherwise, spatial reuse may be permitted.

9. A wireless device comprising:
-
a processor to determine whether to allow spatial reuse upon receipt of a request for a communication between two devices, said processor to determine, in response to said request, whether bandwidth exists for a communication in a given time period, said processor to provide a primary reservation in response to said request if an available channel has resources available, and said processor to find a channel with sufficient duration with only one act of communication if there is no available channel of sufficient length without communications; and a directional antenna coupled to said processor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
