摘要： Methods and apparatuses for reducing the overhead associated with transmitting MAPs are provided by grouping client stations in different constellations into one of two or more groups/allocations based partially upon their respective channel conditions. As a result of grouping, client stations within each group/allocation share a single resource allocation and in addition, the different groups of client stations can be scheduled such that variable modulation repeat-coding schemes can be implemented for map transmissions to each group, thereby reducing the repetition rates and overhead associated with map transmissions.

摘要： An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes. These principles can be expanded upon and can be applied in many communication systems.

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： Enhanced frame preambles facilitate co-channel co-existence in a wireless communication environment by having at least one preamble characteristic that connotes channel-sharing information regarding the wireless communication environment. In an exemplary embodiment, a downlink subframe is received in one or more wireless communication signals in a wireless communication environment. A preamble is detected in the downlink subframe, and at least one characteristic of the preamble is ascertained. Channel-sharing information for the wireless communication environment is determined based upon the at least one characteristic of the preamble. In another exemplary embodiment, a channel is scanned to detect secondary preambles being transmitted on the channel. A current preamble configuration, including a permutation of preamble location and preamble content corresponding to the secondary preambles, is determined, which connote channel-sharing information. A next available preamble location may be adopted based on the current preamble configuration.

摘要： A wireless broadcast system that collects content for distribution over a wireless communication network. Multiple content streams are received and interleaved into an aggregate content stream. The aggregate content stream is encapsulated into a stream of transport packets that are ruggedized for broadcast over the wireless communication link. One connection identification is associated with the entire aggregate content stream. The aggregate content stream is packetized into multiple service data units. An identical signal that includes the service data units and one connection identifier is broadcast by multiple synchronized transmitters in a single frequency network. The content can include multimedia data, such as audio/video data, movies, game, audio broadcasts, television network programs, or other types of multimedia content.

摘要： A base station can communicate resource allocation to a wireless mobile station in an uplink map information element. The base station can identify destination mobile stations using a shorthand connection identifier. The base station parses the connection identifier field into a shorthand connection identifier field and an embedded subfield data field. The shorthand connection identifier field can be sized to support a predetermined number of mobile stations. The base station can further parse the embedded subfield field into a number of sub-fields, each communicating a different set of control information. In one embodiment, the base station utilizes the embedded subfield to communicate power, timing, and frequency information to the destination mobile station.

摘要： Detecting a boundary between training sequences in a transmission is an important operation. In many communications systems, there are no special boundaries or markers to denote the end of one sequence and the beginning of another. Correlation has been a commonly used technique to detect sequences and a fall in the correlation can be used to indicate such boundaries, but classical correlation can be slow and a significant portion of the new sequence is received prior to the boundary being detected. A method and apparatus is presented that allows rapid detection of the boundary and only a small amount of the new sequence needs to be received prior to the detection of the boundary. Additionally, the method and apparatus can be used to detect the presence of a transmission on the communications medium.
