摘要： The subject matter disclosed herein provides a mechanism for identifying packet boundaries in a data table, such as a Reed-Solomon table. The method may include receiving one or more packets for insertion into a table. A first indicator may be inserted into the table. The first indicator may be associated with one or more rows of the table and may identify whether each of the one or more rows includes one or more fragments (e.g., a packet beginning, a packet ending, and the like). In each of the rows identified by the first indicator as including one or more fragments, a second indicator may be inserted. The second indicator may represent a length in bytes of at least one of the corresponding packet fragments. Related systems, apparatus, methods, and/or articles are also described.

摘要： Redistribution of multimedia signals or the like within a service area is performed by identifying one or more pieces of white space in the VHF/UHF spectrum, selecting a carrier frequency for each piece of white space spectrum, parsing the signal into a like number of components and modulating each component over a carrier frequency. The receiving device performs the reverse operation for reconstructing the signal.

摘要： A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. In accordance with this technique, currently active CPEs request bandwidth using previously unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE. By using a combination of bandwidth allocation techniques, the present invention advantageously makes use of the efficiency benefits associated with each technique.

摘要： Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

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.

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： 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.
