First Claim
Patent Images
1. A method of providing contention access to a communication medium in a communications network, comprising:
- transmitting priority information with each of a plurality of network nodes prior to a shared-contention transmission opportunity, the priority information for each node indicating a priority level of a frame that the node intends to transmit on the communication medium during the shared-contention transmission opportunity; and
assigning at least one of the nodes to a contention window of a plurality of contention windows within the transmission opportunity based on the transmitted priority information.

Abstract
A method of providing contention access to a communication medium in a communications network includes transmitting priority information with each of a plurality of network nodes prior to a shared-contention transmission opportunity. The priority information for each node indicates a priority level of a frame that the node intends to transmit on the communication medium during the shared-contention transmission opportunity. At least one of the nodes is assigned to a contention window of a plurality of contention windows within the transmission opportunity based on the transmitted priority information.

21. A method of providing a shared-contention transmission opportunity in a communications network, comprising:
-
transmitting priority information onto a communication medium of the network with each of a plurality of network nodes prior to the shared-contention transmission opportunity, the priority information for each node indicating a priority level of a frame that the node intends to transmit during the shared-contention transmission opportunity; providing a plurality of priority-based contention windows within the transmission opportunity; and determining a size for each of the contention windows based on the transmitted priority information.
