Abstract
Systems and methods are described to concurrently utilize actively used spectrum for new TDD or FDD networks, and also for enabling Distributed-Input Distributed Output (DIDO) techniques to be used with both the new networks and the existing networks in the same spectrum.
Claims6
A system of two overlapping wireless networks comprising:
- a first wireless network in ultra high frequency (“UHF”) spectrum configured in frequency division duplex (“FDD”) mode comprising a first plurality of wireless base stations (“BTSs”) within a first coverage area;
- a second wireless network in microwave spectrum comprising a second plurality of BTSs overlapping the first coverage area;
- wherein the first and second wireless networks are configured to operate utilizing carrier aggregation (“CA”);
- wherein multiple simultaneous non-interfering orthogonal frequency-division multiple access (“OFDMA”) data streams within a same frequency band between the first wireless network and a first plurality of user equipment devices (“UEs”) are delivered;
- and
- wherein the second wireless network operates in time division duplex (“TDD”) mode in a same spectrum as the FDD downlink of the first wireless network.
