Trigger frames adapted to packet-based policies in an 802.11 network
摘要
說明書
In other embodiments, the method further comprises determining the number of resource units forming the communication channel, based on network statistics on one or more previous transmission opportunities. This contributes to improve network usage since the number of nodes that can transmit data during the next TXOP is dynamically adjusted to the network conditions.
In specific embodiments, the network statistics include one or more from:
a number of nodes registered to the access point in the wireless network,
a number of collisions or a collision ratio (number of colliding RUs out of the number of RUs) occurring during the one or more previous transmission opportunities,
a distribution of packet sizes received by the access point, in particular a packet size distribution relative to a maximum packet size (i.e. defining the small packets),
an amount of data transmitted by the nodes,
an amount of data transmitted by the nodes for each traffic type from among a plurality of predefined traffic types,
a ratio of medium busyness, for instance the ratio of a medium busy time on a given period (e.g. one second).
In embodiments, the trigger frame includes a single indicator that define the same restricted type of data for all the resource units of the at least one communication channel, i.e. for the whole composite channel. Overhead due to the indicator is thus minimized.
