Abstract: The present invention provides a method of calibrating base station comprising a plurality of antennas and operating in an Orthogonal Frequency Division Multiplex (OFDM) and Time Division Duplex (TDD) mode. One embodiment of the method includes a method of calibrating a base station comprising a plurality of antennas for beamsteering forward link traffic data to a target mobile in a TDD wireless communication system. Each antenna is connected to a corresponding radio via a transmit/receive switch that is configured to switch between a receive path and a transmit path. The method includes transmitting a first signal from a first radio via a first cross-over cable coupled to the first radio and a second radio such that the first signal is received by the second radio. The method also includes transmitting a second signal from the second radio via a second cross-over cable coupled between the first and second radios such that the second signal is received by the first radio.

Abstract: The present invention provides a method of scheduling uplink transmissions from at least one access terminal to an access network. The method includes estimating, at the access network, at least one signal-to-noise ratio associated with each access terminal and determining, at the access network, a format for the packet based upon the estimated signal-to-noise ratio. The method also includes ranking access terminals and allocating, at the access network, resources to access terminals for transmission based on each access terminal's priority and the determined format of the packet and transmitting, from the access network, information indicative of the resources allocated to each access terminal.

Abstract: A method of wireless data communication. The method includes the step of receiving a feedback indicator signal at two or more points in space from two or more transmission paths. Each transmission path may correspond with a wireless unit seeking to communicate over a downlink and/or an uplink. The method, thereafter, includes the step of measuring a relative phase difference between the feedback indicator signals of two or more transmission paths. Subsequently, one spreading code may be assigned to two or more transmission paths if the measured relative phase difference between their feedback indicator signals corresponds with minimal mutual interference. Consequently, two or more wireless units having a measured relative phase difference in the range of about 90 degrees and about 270 degrees, for example, may use the at least of the same spreading codes.
