==NON-CONTIGUOUS CHANNEL ALLOCATION OVER MULTI-CHANNEL WIRELESS NETWORKS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18351298 titled 'NON-CONTIGUOUS CHANNEL ALLOCATION OVER MULTI-CHANNEL WIRELESS NETWORKS

==Simplified Explanation==

The abstract describes a method for transmitting data in a wireless network using 802.11ac technology. The method involves sending RTS frames from the source to the receiver to request reservation of a composite channel. The RTS frames include a flag indicating that the source supports transmission over unauthorized composite channels, such as non-contiguous sub-channels within the operating band. The receiver responds with CTS frames acknowledging the reservation of the unauthorized composite channel configuration. The source then transmits data frames on the reserved sub-channels of the unauthorized configuration, such as non-contiguous sub-channels within the operating band.

* Method for transmitting data in a wireless network using 802.11ac technology
* RTS frames sent from source to receiver to request reservation of a composite channel
* RTS frames include a flag indicating support for transmission over unauthorized composite channels
* Receiver responds with CTS frames acknowledging reservation of unauthorized composite channel configuration
* Source transmits data frames on reserved sub-channels of unauthorized configuration
* Data frames transmitted on non-contiguous sub-channels within the operating band


==Original Abstract Submitted==

802.11ac networks define an operating band made of an ordered series of 20 MHz channels and authorize a restricted number of possible composite channel configurations to be used for data transmission. A method of transmitting data between a source and a receiver in such a wireless network may comprise, at the source: sending, to the receiver, RTS fames to request reservation of a composite channel, the RTS frames including a flag signalling the source supports transmission over un-authorized composite channels, for instance over sub-channels not contiguous within the operating band; receiving, from the receiver in response to the RTS frames, CTS frames acknowledging reservation of un-authorized composite channel configuration, for instance of non-contiguous sub-channels; and then transmitting, to the receiver, data frames on the reserved sub-channels of the un-authorized configuration, for instance on the reserved non-contiguous sub-channels within the operating band.
