    摘要： A method is disclosed to eliminate inter-cluster interference of user equipment located at the edge of a cluster of cells. The method operates by employing fractional frequency reuse (FFR) principles on clusters or combinations of cells in a wireless neighborhood, in which base stations in the cells coordinate their operations in a scheme known as coordinated multi-point transmission (CoMP). By using the FFR principles to single out edge users of the CoMP cluster, the method mitigates interference and increases throughput for the edge users.

    摘要： In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node. Techniques are described herein that can be used to flexibly set a number of sub-channels over which a subscriber station indicates a channel quality indicator to a base station. Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.

    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.
