Method and device for establishing communication links and handling SP slot connection collisions in a communication system
First Claim
1. A wireless communication network comprising:
- a plurality of mobile nodes each comprising a transceiver, a directional antenna connected to said transceiver, and a controller connected to said transceiver and comprising a first time slot unit to schedule a respective semi-permanent time slot for each time frame to establish a communication link with each neighboring mobile node and leaving at least one available time slot in each time frame, a second time slot unit to schedule the at least one available time slot to also serve the communication link with a neighboring mobile node based upon link communications demand, an antenna aiming unit to aim said directional antenna toward each neighboring mobile node during communication therewith, each communication link being formed by two mobile nodes, an initiating mobile node transmitting a request for time slots to a receiving mobile node, and the receiving mobile node transmitting a reply to the initiating mobile node, the controller of each mobile node waiting a time period to resend another request when each mobile node simultaneously receives a request from the other mobile node and does not receive a corresponding reply.

Abstract
A wireless communication network includes a plurality of mobile nodes each including a transceiver, a phased array antenna connected to the transceiver, and a controller connected to the transceiver. The controller schedules a respective semi-permanent time slot for each time frame to establish a communication link with each neighboring mobile node and leaves at least one available time slot in each time frame. The controller also schedules the at least one available time slot to also serve the communication link with a neighboring mobile node based upon link communications demand. The controller waits a time period to resend another request upon simultaneously sending a request to an other mobile node and receiving a request from the other mobile node without receiving a corresponding reply.

19. A method for establishing communication links for a plurality of mobile nodes, each mobile node comprising a transceiver, a directional antenna connected to the transceiver, and a controller connected to the transceiver, the method comprising for each mobile node:
-
scheduling a respective semi-permanent time slot for each time frame to establish a communication link with a neighboring mobile node and leaving at least one available time slot in each time frame;
scheduling the at least one available time slot to also serve the communication link with a neighboring mobile node based upon link communications demand;
aiming the directional antenna toward each neighboring mobile node during communication therewith;
each communication link being formed by two mobile nodes, an initiating mobile node transmitting a request for time slots to a receiving mobile node, and the receiving mobile node transmitting a reply to the initiating mobile node;
the controller waiting a time period to resend another request upon simultaneously sending a request to an other mobile node and receiving a request from the other mobile node without receiving a corresponding reply. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
