Patent ID: 7339926

Claim:
A method for communicating between half-duplex nodes and a base station, where at least one half-duplex node is to transmit on an uplink channel and receive on a downlink channel in a frequency division duplexing (“FDD”) manner, the method comprising: transmitting modulated data from the base station to a first half-duplex node during a first time frame on a first channel; receiving modulated data from a second half-duplex node at the base station during the first time frame on a second channel, the first and second half-duplex nodes being different nodes, and the transmitting and the receiving in the first time frame occurring substantially simultaneously; transmitting modulated data from the base station to the second half-duplex node during a second time frame on the first channel, wherein the first time frame precedes the second time frame; and receiving modulated data from the first half-duplex node at the base station during the second time frame on the second channel, the transmitting and the receiving in the second time frame occurring substantially simultaneously.
