摘要： A method of performing channel assessment, the method comprising transmitting via a set of aggregated channels that comprise a primary channel and at least one non-primary channel; determining that a channel assessment on a non-primary channel is to be triggered; based on the determining, triggering a channel assessment event on the non-primary channel; receiving a frame via the non-primary channel, wherein the frame is sent in response to the channel assessment event; and determining a channel quality for the non-primary channel based on the received frame.

摘要： A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non- primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel, Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective qualify values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.

摘要： A wireless communication network comprises a plurality of stations and a central entity, wherein a plurality of different radio access technologies are deployed in the wireless communication network and the central entity coordinates and manages wireless communications in the wireless communications network. A method for wireless direct link operations in the network comprises: a direct link station setting up a direct link with a peer direct link station, wherein a first set of channels is assigned for the direct link and a second set of channels is assigned for a link to the central entity; the direct link station performing CSMA on a primary channel of the direct link; and the direct link station sending a packet to the peer direct link station on the first set of channels on a condition that a transmission opportunity is obtained via the CSMA performed on the primary channel of the direct link.
