Patent ID: 8811297

Claim:
A method of controlling the access to a common radio channel by nodes in a wireless multihop communication network for multihop traffic from a source node to a destination node wherein the network comprises a plurality of relay nodes and a centralized node managing the access control, the method comprising: initiating and issuing, by a relay node having to access the channel, a cumulative request to the centralized node for the resources needed on each link of a multi-hop path up to the destination node, where said relay node is the origin of the cumulative request and where in a presence of traffic belonging to different classes of service, said cumulative request issued by said relay node comprises a concatenation of a plurality of individual cumulative requests each concerning traffic belonging to a different class of service, wherein the centralized node, in response to said plurality of concatenated requests from a relay node, is arranged to generate a single undifferentiated grant message for all classes of service of the individual requests, wherein said single undifferentiated grant message is concatenated with said plurality of individual requests.
