    摘要: Methods and systems for operating a base station communicating with one or more user terminals in an orthogonal frequency division multiple access (OFDMA) system where the one or more user terminals are configured to insert pilots in up stream bursts every nth symbol on each subcarrier, where n is an integer, are provided. The method includes identifying a needed amount of up stream bandwidth to be allocated to a user terminal; determining the subcarriers and the number of symbols per subcarrier to be allocated to meet the identified need in a burst; allocating, for the user terminal, a set of subcarriers and a number of symbols for each member of the set of subcarriers, wherein sufficient symbols per subcarrier per burst are allocated to allow user terminal to send two or more pilots per subcarrier per burst; and transmitting a message to the user terminal, the message identifying the allocated subcarriers and the number of symbols allocated for each subcarrier.

    摘要: A two-level database structure for use by unlicensed TVBD devices operating in TV white space comprises a central database and local databases. The central database comprises two sub-database: the central licensed database which maintains information about all licensed TV devices and the central unlicensed database which maintains information about unlicensed wireless devices operating in TV spectrum. The local database is created by each TVBD device or TVBD network when it initiates and it stores information related to all transmitters in the local area including location, power transmission levels, operating schedule, sensing results, backup channel information. The local databases communicate with central database to query it about licensed usage of TV spectrum and register with central database. The local databases communicate with each other to exchange information about channel usage, sensing results, transmission patterns and other information that will allow the local databases to negotiate coexistence without central coordinator. The locally implemented negotiation prevents the overloading of the central database.

    摘要: A frequency resource allocation system and method for a wireless network that comprises one or more unlicensed cognitive devices that operate using white spaces in a TV frequency spectrum and one or more licensed incumbent devices that are associated with an incumbent service that uses the TV frequency spectrum stores one or more frequency resource databases that store one or more frequency band lists. A frequency band list comprises one or more frequency bands within the TV frequency spectrum. Merit-related information specific to a location associated with the wireless network are collected to choose a specified frequency based on the merit-related information. The specified frequency band can be chosen based on a merit class derived from transforming the merit-related information into different merit classes, with each merit class being associated with one or more frequency bands. A resource user device is then notified to operate in the specified frequency band.
