    摘要: A channel normally used to transmit acknowledgement of successful signal receipt and an indication of unsuccessful signal receipt is adopted to transmit power control information from a base station to a mobile station. The power control information can be encoded as a binary code where each value of the code is indicated by an acknowledgement or non-acknowledgement signal.

    摘要: A weighted tone reservation (WTR) method and system are disclosed, for PAPR reduction. The WTR method solves the peak re-growth problem with minimum overhead. By avoiding the drawbacks of conventional tone reservation approaches, systems employing the WTR method may experience a significant PAPR reduction. The WTR method may be applied to next generation OFDMA-based wireless broadband technologies to increase system throughput and cell coverage.

    摘要: A method and apparatus for wireless location tracking by a wireless device. In one embodiment of the invention, the wireless device has logic to determine the information of a plurality of specific location points and to determine the location of the wireless device based on the information of the plurality of specific location points. The specific location points are selected from a target area where the wireless device is located. By selecting the specific location points in the target area, it allows hidden Access Points (APs) or Base Stations (BSs) to be detected and measured and it increases the accuracy of the tracking of the wireless device.

    摘要: A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.
