Abstract:
1. A method of coordinating two or more networks to share spectrum, comprising: receiving, with a spectrum management server, a spectrum allocation request from one of the networks, the spectrum management server having previously allocated spectrum by generating and transmitting a first spectrum allocation to another one of the networks for use in wireless communications, the first spectrum allocation including a first set of spectrum sharing spreading codes; matching, with the spectrum management server, the spectrum allocation request to available spectrum to identify matched spectrum, the matched spectrum comprising spectrum that is the same in each of time, frequency and location as spectrum allocated in the first spectrum allocation and used by the another one of the networks for wireless communications; and generating, with the spectrum management server, a second spectrum allocation and transmitting the second spectrum allocation to the requesting network, the second spectrum allocation including the spectrum that is the same in each of time, frequency and location and including a second set of spectrum sharing spreading codes different than the spreading codes in the first set of spectrum sharing spreading codes, the second set of spectrum sharing spreading codes used by the requesting network to carry out wireless communication using the spectrum that is the same in each of time, frequency and location and without interference to the wireless communications of the another one of the networks, the another one of the networks and the requesting network being individual networks that each respectively include a plurality of radio devices that are administered as a unit and communicate with each other within the network in accordance with the spectrum allocation for the respective network.
