    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: Examples are disclosed for analyzing uplink interference or pathloss associated with uplink coverage provided by one or more base stations for a wireless network based on logged uplink signal quality or interference information at least temporarily maintained at a wireless device. In some examples, a base station may request the logged uplink signal quality or interference information from the wireless device. The wireless devices may have been configured to measure uplink signal quality or interference characteristics for one or more communication links between the wireless device and one or more base stations of the wireless network. The logged uplink signal quality or interference information may be based on the measured uplink signal quality or interference characteristics. Other examples are described and claimed.

    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.
