摘要： A device in a wireless system may determine when communications of a first radio access technology (RAT) experience interference from communications of a second RAT and may alter the communications of at least the first RAT or the second RAT to reduce the interference. In some instances, altering the communications include controlling a transmission rate to the second RAT based at least on a determined channel capacity.

摘要： Methods and apparatus for providing a wireless expansion network. In an aspect, an apparatus includes an expansion circuit configured to identify at least one of a selected uplink (UL) channel and a selected downlink (DL) channel that are provided by one of a primary network and an expansion network, and a processing circuit configured to switch to the at least one of the selected UL and DL channels. An apparatus includes means for obtaining link parameters associated with a primary network and an expansion network, means for identifying clients that are assigned transmission channels on both the primary network and the expansion network based on the link parameters, and means for transmitting messages to the clients to indicate the assigned transmission channels.

摘要： Multichannel dynamic frequency selection in wireless networks begins with an access point for a wireless network broadcasting a list of unused channels that are available for communication within the area served by the access point. The various access terminals within this service area receive the broadcast and measure various interference characteristics of each of the channels in the list. The access terminals then send this interference information to the access point, which compiles a matrix of interference information that is associated with the quality of each signal as related to each access terminal. Using this information, the access point selects the appropriate channels to serve the most number of access terminals at the highest possible channel qualities.

摘要： Techniques for use in contending for a portion of a television channel spectrum are disclosed. In some instances, a back-off value is used to decide whether a contender's contention number will be transmitted when the contention channel is free, and the back-off value is determined based on the contention number. In some instances, a contender monitors the contention channel and withdraws from contention if it detects from the contention channel that a higher priority contender is in contention.

摘要： Methods and apparatuses for providing a wireless expansion network in a client device. In an aspect, an apparatus at a client device (516, 518, 520, 522) comprises means for receiving, from a network device, one or more messages indicating an assigned transmission mode, said transmission mode being one of the following four transmission modes: primary up-link and primary down-link, primary up-link and expansion down-link, expansion up-link and primary down-link and expansion up-link and expansion down-link. Thereby are primary down-link or up-link channels supported by a primary network and the expansion down-link or up-link channels supported by an expansion network. Each of the primary network and the expansion network operates in its own frequency band with different propagation characteristics and emission limits, and the expansion network utilizes unlicensed spectrum having a transmission limit that is lower than for a licensed spectrum used by the primary network.
