US 7869378 B2Abstract
1. A mesh node comprising:
a processor configured to generate a message including a list of allocated slots based on the stored slot allocation information, wherein an information field of the message includes a list size subfield, a plurality of information subfields for each of the slots, and a slot number list size subfield, wherein each slot information subfield comprises a timing information field, an RF information field, a quality of service (QoS) information field, a peer nodes information field, and a direction field; and
a transmitter configured to transmit the message to another mesh node.
2. The mesh node of claim 1 wherein the mesh node operates in a wireless local area network (WLAN).
3. The mesh node of claim 1 wherein the processor is further configured to include a slot report in an action frame used by a medium access control (MAC) entity.
4. The mesh node of claim 3 wherein the slot report transmits slot allocation schedule information associated with the mesh node to another mesh node.
5. A method for transmitting slot allocation information, the method comprising:
storing slot allocation information associated with a mesh node;
generating a message, including a list of allocated slots, based on the stored slot allocation information, wherein an information field of the message includes a list size subfield, a plurality of information subfields for each of the slots, and a slot number list size subfield, wherein each slot information subfield comprises a timing information field, an RF information field, a quality of service (QoS) information field, a peer nodes information field, and a direction field; and
transmitting the message to another mesh node.
6. The method of claim 5 wherein the mesh node operates in a wireless local area network (WLAN).
including a slot report in an action frame used by a medium access control (MAC) entity.
8. The method of claim 7 wherein the slot report transmits slot allocation schedule information associated with the mesh node to another mesh node.
9. A mesh node comprising:
a receiver configured to receive a first message including a list of allocated slots, from a second mesh node;
a memory configured to store an information element (IE), wherein the IE comprises a list size subfield, a plurality of information subfields for each of the slots, and a slot number list size subfield, wherein each slot information subfield comprises a timing information field an RF information field, a quality of service (QoS) information field, a peer nodes information field, and a direction field;
a processor configured to retrieve the IE from the memory and generate a second message that includes a response to the first message, that includes the IE in response to the receiver receiving the first message; and
a transmitter configured to transmit the second message to the second mesh node.
10. The mesh node of claim 9 wherein the element ID field and the length field are each one octet in length.
11. The mesh node of claim 9 wherein the information field comprises:
12. The mesh node of claim 11 wherein each slot information field comprises:
13. The mesh node of claim 11 wherein each slot information field comprises:
14. The mesh node of claim 11 wherein each slot information field comprises:
15. The mesh node of claim 11 wherein each slot information field comprises:
16. The mesh node of claim 9 wherein the first and second mesh nodes operate in a wireless local area network (WLAN).
When the receiver 340 in the node 310 receives the list of allocated slots request message 360, the processor 345 retrieves the IE 100 from the memory 350 and generates a list of allocated slots response message 365 which includes the IE 100, which is transmitted by the transmitter 335 via the antenna 352 of the node 310. Each of the processors 325 and 345 include a MAC entity (not shown) which facilitates the generation of the list of allocated slots request message 360 and the list of allocated slots response message 365.
