Abstract

Claims (16)

1 . 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.

2 . The system in claim 1 wherein communications over both the first and second wireless networks can be concurrently received by the first plurality of UEs.

3 . The system in claim 1 wherein the CA is utilized to enable one or more of the first plurality of UEs to establish data links between both the first and second wireless networks concurrently.

4 . A method implemented within 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 BTSs within a first coverage area;

a second wireless network in microwave spectrum comprising a second plurality of BTSs overlapping the first coverage area; and

utilizing carrier aggregation (“CA”) with the first and second wireless networks;

delivering 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”); and

operating the second wireless network operating in time division duplex (“TDD”) mode in a same spectrum as the FDD downlink of the first wireless network.

5 . The method in claim 4 further comprising the first plurality of UEs concurrently receiving communications over both the first and second wireless networks.

6 . The method in claim 4 further comprising the CA to enable one or more of the first plurality of UEs to establish data links between both the first and second wireless networks concurrently.
