    摘要: A codebook generation system and associated methods are generally described herein. For instance, a codebook generation agent (CGA) may implement techniques for generating one or more matrix codebooks from vector codebooks. The CGA may be implemented in mobile devices (e.g., stations, subscriber units, handsets, laptops, etc.). In this regard, the dynamic generation of matrix codebooks rather than having them stored on the mobile device enables the mobile device to utilize the memory normally consumed by the matrix codebooks in support of other features and/or services.

    摘要: Embodiments of a base station and methods for allocating uplink bandwidth using SDMA are generally described herein. In some embodiments, uplink bandwidth request messages are received on a bandwidth request contention channel from one or more subscriber stations. The uplink bandwidth request messages are generated by the subscriber stations by modulating pilot subcarriers of a randomly selected disjoint pilot pattern with a randomly selected orthogonal sequence. The base station allocates uplink bandwidth to the subscriber stations when the uplink bandwidth request messages are successfully detected and decoded. The base station uses an SDMA technique to determine channel responses based on the orthogonal sequences to detect and decode the uplink bandwidth request messages.

    摘要: Embodiments of a base station and method for resource allocation using localized and distributed resource blocks are generally described herein. The base station comprises processing circuitry to allocate localized resources to user stations based on receipt of channel quality information received from the user stations and to allocate distributed resource to user stations based on non-receipt of channel quality information. The base station also comprises physical layer circuitry to transmit control information on a physical channel to indicate the resources that are allocated to each scheduled user station.

    摘要: Embodiments of the present invention may help facilitate improved performance for high throughput, mobile wireless networks, e.g., IEEE 802.16m, mobile implementations for 3GPP Long Term Evolution (LTE) including LTE advanced mobile phone networks, and other types of high bandwidth networks. In some embodiments, provided are orthogonal sequences with desirable correlation properties for, e.g., 4-6 bits of information, among other things, typically achieving improved performance at varied vehicle speeds. In some embodiments, correlation distances for 6 bits may be less than 3.86, for 5 bits may be less than 3.12, and for 4 bits may be less than 1.95. Additionally, in some embodiments, dedicated coding for PFBCH information may be provided to achieve improved performance for most (if not all) information bits at a relatively wide range of vehicle speeds. Different code sequences for different tiles in one PFBCH channel may be applied for same messages to overcome error floors in high speed scenarios.

    摘要: A receiver for use in performing open loop MIMO performs parallel interference cancellation to reduce interference caused by other spatial streams. Residual interference within an interference-cancelled signal is mitigated using MMSE filtering. The receiver processes received signals in multiple iterations. On each successive iteration, an MMSE filter assumes a lower interference power level than a previous iteration.
