    摘要: Methods and apparatus are provided to enable aperiodic sounding reference signaling including frequency hopping through the use of additional RRC configuration. The methods can require little or no additional L1 overhead to support narrowband frequency hopping for aperiodic sounding transmissions. In some embodiments, an approach is provided for extending an LTE periodic sounding reference signal methodology to include aperiodic sounding. One benefit of the proposed technique is that it enables each UE to perform aperiodic channel sounding in sounding subframes, using a frequency-hopping pattern, in which the sounding bandwidth of the UE can be narrowed appropriately to match its link capability. Additional benefits of the new approach include better resource utilization, lower signaling overhead, faster channel information update rates, and lower blocking probabilities.

    摘要: A novel system for performing adaptive beamforming in a slow frequency hopping environment is disclosed. The presence of slow frequency hopping means that conventional mechanisms of using beamforming weights from previous time slots are inapplicable. The inventive system calculates a series of beamforming weights from an estimate of the spatial location of the mobile subscriber in the previous frame, which is impervious to slow frequency hopping and the data that precedes the training sequence data of the current frame. The beamforming weights and the spatial location of the mobile are updated with the arrival of the entirety of the current frame. The initial beamforming weight estimate is sufficient to permit processing on a real-time basis of the current frame even if the inventive system is implemented as an appliqué system interposed between the antenna array and a conventional base station.

    摘要: A system and method of providing an adaptive multi-beam capability to a wireless base transceiver station is disclosed. The system comprises a plurality of transmit and receive antenna arrays and a plurality of static beamformers to form a limited number of beams. The beam data is reduced to digital baseband form whereupon it is digitally beamformed using a set of adaptive beamforming weights generated having regard to the form and content of the data and the environment. Such form and content information is obtained directly or indirectly from the base transceiver station. The weights are calculated using an average power function derived from a correlation of the beam data with a reference signal that mimics the training sequence assigned to the base transceiver station. Because the average power does not vary widely from frame to frame, the weights derived from the uplink direction may be reapplied in the downlink direction. Specific provision is made for data packets, where downlink packets may contain control information intended for broadcast to all subscribers.
