Method and apparatus for interference management between networks sharing a frequency spectrum
A method and system are provided that allows a wireless terminal to share an allocated frequency spectrum for communications over two different networks while mitigating cross interference. For wireless terminals equipped with a single antenna, interference mitigation may be achieved by allocating first communication channels to a first network and allocating second communication channels to a second network, wherein the second communication channels are allocated within one or more of the first communication channels. For wireless terminals having multiple antennas, interference mitigation may be achieved with two orthogonally polarized antennas, where each antenna is used for communications with a different network. Consequently, a wireless terminal having a channel allocation for communicating over the first wireless network may reuse the same channel allocation to establish a communication link with a second wireless terminal via a second wireless network using at least part of the channel allocation for the first wireless network.
