說(shuō)明書(shū)
The same first main embodiments of the invention provide, from the node's perspective, a wireless communication method in a wireless network comprising an access point and a plurality of nodes, the method comprising, at one of said nodes:
receiving a trigger frame from the access point, the trigger frame reserving at least one communication channel of the wireless network for a transmission opportunity and defining a plurality of resource units forming the communication channel;
determining, from the trigger frame, an indicator defining a restricted type of data authorized for at least one of the resource units:
determining, from local transmitting memory, data having a type corresponding to the determined restricted type of data; and
transmitting the determined data to the access point on the said resource unit.
Thanks to the indicator specifying the restricted type of data, the Access Point is able to drive or control the nodes in their process of selecting data to transmit on the RUs. As a consequence, the AP may efficiently adapt the RUs to data types, resulting in optimizing the use of the RUs.
Correlatively, the invention provides a communication device acting as an access point in a wireless network also comprising a plurality of nodes, the communication device acting as an access point comprising at least one microprocessor configured for carrying out the step of sending a trigger frame to the nodes, the trigger frame reserving at least one communication channel of the wireless network for a transmission opportunity and defining a plurality of resource units forming the communication channel,
