Effective support beamforming with duplex time division by causing the frequency hopping and the control signal ON REQUEST

摘要

1. A method for improving the utilization of bandwidth and provide support beamforming antennas in a time division duplex wireless communication environment, comprising the steps of: Evaluation is carried segment frequency band used by a subscriber unit when the received transmission on the reverse link, and! produce the transmission signal in a subscriber unit in a subsequent transmission time interval on the forward link using the same frequency band segments. ! 2. The method of claim 1, comprising the additional steps of: a subscriber unit is assigned a new network bandwidth, pre-hopping for use in the next transmission time interval for the reverse link and produce a frequency hopping bandwidth segments in the forward link according to scheme segment hopping frequency which was used in a previous transmission on the reverse link. ! 3. The method of claim 2 comprising the following further step: checking, the new bandwidth segment can the be made available. ! 4. The method of claim 3, comprising the following additional step: scheduling transmission on the forward link in the designated segment with preformed frequency hopping. ! 5. The method of claim 4, wherein the available bandwidth for communication between the device and a plurality of subscriber units is divided into segments of a width of about 5 MHz. ! 6. The method of claim 3, comprising the additional steps of: in the event that the segment with prefaces
