摘要： A method and apparatus for adaptively obtaining bandwidth requests in a broadband wireless communication system. The method and apparatus includes dynamically varying technique combinations enabling a plurality of users to efficiently request bandwidth from a shared base station. A user may “piggyback” a new bandwidth request upon, or set a “poll-me bit” within, presently allocated bandwidth. A base station may poll users, individually or in groups, by allocating unrequested bandwidth for new requests. Polling may respond to a “poll-me bit,” and/or it may be adaptively periodic at a rate based on communication status parameters, such as recent communication activity and connection QoS levels. Group polling permits a possibility of collisions. Polling policies may be established for dynamically varying user groups, or may be determined for each user. Dynamic selection of appropriate polling techniques makes use of efficiency benefits associated with each technique.

The method may include determining one or more singular vectors using a closed form singular value decomposition. The one or more determined singular vectors may be provided to a precoder at the base station as feedback. The method may include aligning a phase of one or more singular vectors. The method may also include determining, at a client station, a plurality of singular vectors for channels used in a MIMO transmission from a base station to a client station. The client station may provide an indication to the base station regarding whether to use a singular value decomposition or a uniform channel decomposition. Related systems, apparatus, methods, and/or articles are also described.

摘要： Whitespace devices can use unused television frequencies for transmission and reception of WiFi OFDM signals. Three contiguous bands, such as former channels 2, 3, and 4, may be bonded together to define a whitespace band. In order to fit a WiFi OFDM signal into this whitespace band, a whitespace device compresses the bandwidth of each WiFi OFDM signal using a specific spectrum mask. Very low transmission power is needed for the modified WiFi OFDM signals, eliminating the need for high power amplifiers and most of the WiFi OFDM designs such as PHY and MAC can be reused with minor modifications.
摘要翻译：空白设备可以使用未使用的电视频率来发送和接收WiFi OFDM信号。诸如前通道2,3和4之间的三个连续的波段可以结合在一起以限定空白波段。为了将WiFi OFDM信号装入该空白频带，空白设备使用特定的频谱掩模来压缩每个WiFi OFDM信号的带宽。对于经修改的WiFi OFDM信号需要非常低的发射功率，消除了对大功率放大器的需要，并且可以重复使用大多数诸如PHY和MAC的WiFi OFDM设计。

摘要： A configuration for downlink signals in a wireless communication system, methods of configuring the downlink signals, apparatus for generating the downlink signals, and apparatus for receiving and processing the downlink signals are described herein. Downlink signals in a wireless communication system are reconfigured in series of frames, with each frame carrying a preamble that provides fast cell search and system acquisition. In particular, the preamble includes a primary preamble and a secondary preamble, where the primary preamble is common to all sectors in a base station and all base stations in a system and the secondary preamble is effectively unique to each base station, and may be further distinguished based on a sector basis. In addition, pilot signals are aligned with base stations to occur at the same time within a frame and the PN sequence values of the pilot signals are based on a cell identification an antenna identification, thereby enabling prediction of pilots transmitted by interferers or neighboring base stations from acquisition of secondary preambles. Also, the pilot bits are selectively assigned from a center of an operating band outward. Due to the pilot placement and pilot modulation, the scheme enables interference mitigation and channel estimation without knowing the frequency bandwidth, which is especially advantageous in broadcast channel systems.

摘要： A multicast broadcast service controller is disclosed. The MBSC processes multicast broadcast data streams for transmission to access service network gateways or base stations. The MBSC includes a MBSC core processor for establishing time synchronization information used the by the access service network gateways or base stations to synchronously transmit data streams. The MBSC core processor selects streams for transmission in a time diversity interval (TDI) and builds multicast broadcast (MBS) region content based on the selected streams and configuration information. The MBS region content includes timing synchronization information, resource information and MBS region content location information. A MBS region distribution module (MRD) transmits the MBS region content to the access service network gateways or base stations.

摘要： A system and method for proactive repeat transmission of data units sent using an unreliable transmission medium for the delivery of time sensitive data content predicts a future condition of a downlink data distribution channel using current channel estimation information. The predicted channel condition is used to determine which data units in a next data frame are likely to decode incorrectly, and a repeat transmission of those data units is explicitly requested by the receiving equipment, or automatically scheduled by the sending equipment using time domain channel state information provided to the sending equipment by the receiving equipment.
