    摘要： Briefly, in accordance with one or more embodiments, data transmitted from a transmitter is received in a downlink channel, and channel quality data is fed back to the transmitter in a first uplink channel or in a second uplink channel. Channel quality data is feedback at a lower rate on the first uplink channel and channel quality data is feedback at a higher rate on the second uplink channel in the event there is a higher amount of data to be fed back. Link adaptation may be utilized to select a transmission rate on the second uplink channel, wherein the transmission rate is selected based at least in part on a channel condition or a user location.

    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： A multi-radio medium-agnostic access architecture is proposed. The multi-radio medium-agnostic architecture features a medium-agnostic MAC that interfaces between the TCP/IP and the physical layers of user equipment, such as a laptop computer or cellular phone having multiple radios, so that the radios in the user equipment may operate simultaneously, seamlessly, and transparently to higher layers.
