Abstract
A method and system for using half-duplex base stations and half-duplex nodes in a Frequency Division Duplexing region to provide wireless connectivity between the half-duplex base stations and customers in multiple sectors of a cell. The method and system can use two physical channels to form two logical channels. Each logical channel shares both physical channels during alternating frames of time. The half-duplex nodes can include a millimeter-wave band frequency synthesizer configured to transmit and receive on different channels to and from the half-duplex base station. Re-use patterns of the physical channels are used for deployment of half-duplex base stations and half-duplex nodes in the FDD region to minimize co-channel interference and interference due to uncorrelated rain fade. Additional methods and systems utilize full-duplex base stations and smart antenna to communicate with the half-duplex nodes.

68. A time division duplexing wireless communication system comprising:
-
a first half-duplex modem/outdoor unit and a second half-duplex modem/outdoor unit, both configured to alternate in transmitting modulated data over a first channel and receiving modulated data over a second channel; and
a full-duplex modem/outdoor unit configured to alternate between simultaneously transmitting modulated data to the first half-duplex modem/outdoor unit over the second channel while receiving modulated data from the second half-duplex modem/outdoor unit over the first channel and simultaneously transmitting modulated data to the first half-duplex modem/outdoor unit over the second channel while receiving modulated data from the second half-duplex modem/outdoor unit over the first channel. - View Dependent Claims (69, 70)
