Abstract

A system and a method are disclosed for controlling a coordinating network entity in a virtual network including a plurality of access points (APs) and at least one wireless station (STA), including receiving one or more parameters from at least one AP included in the plurality of APs; identifying a first multi-AP coordination scheme based on the one or more parameters; and assigning the first multi-AP coordination scheme to a first dynamic group of network entities included in the virtual network, wherein the first dynamic group of network entities performs wireless communication based on the first multi-AP coordination scheme.

First claim

What is claimed is:

1 . A method performed by a coordinating network entity in a virtual network including a plurality of access points (APs) and at least one wireless station (STA), the method comprising:
receiving one or more parameters from at least one AP included in the plurality of APs; identifying a first multi-AP coordination scheme based on the one or more parameters; and assigning the first multi-AP coordination scheme to a first dynamic group of network entities included in the virtual network, wherein the first dynamic group of network entities performs wireless communication based on the first multi-AP coordination scheme.

2 . The method of claim 1 , further comprising:
assigning a second multi-AP coordination scheme to a second dynamic group of network entities included in the virtual network, wherein the second dynamic group of network entities performs wireless communication based on the second multi-AP coordination scheme.

3 . The method of claim 2 , wherein the first dynamic group of network entities does not include any of the same network entities included in the second dynamic group of network entities.

4 . The method of claim 2 , wherein at least one network entity included in the first dynamic group of network entities is also included in the second dynamic group of network entities.

5 . The method of claim 1 , wherein the at least one or more parameters comprise a link quality metric (LQM) table indicating at least one path loss value between two network entities included in the virtual network.

6 . The method of claim 1 , wherein the at least one or more parameters comprises an uplink or downlink queue size of the at least one STA.

7 . The method of claim 1 , wherein the first dynamic group of network entities are determined based on a network map of relative spatial configurations of one or more of the network entities included in the virtual network.

8 . The method of claim 1 , further comprising:
assigning a second multi-AP coordination scheme to the first dynamic group of network entities included in the virtual network in case that a value of the one or more parameters changes more than a predetermined threshold.

9 . The method of claim 1 , wherein the coordinating network entity is included in at least one of the plurality of APs.

10 . The method of claim 1 , further comprising:
periodically receiving an updated version of one or more of the parameters from the at least one AP included in the plurality of APs.

11 . A virtual network comprising:
a plurality of access points (APs); at least one wireless station (STA); and a coordinating network entity configured to:
receive one or more parameters from at least one AP included in the plurality of APs;
identify a first multi-AP coordination scheme based on the one or more parameters; and
assign the first multi-AP coordination scheme to a first dynamic group of network entities included in the virtual network,
wherein the first dynamic group of network entities performs wireless communication based on the first multi-AP coordination scheme.

12 . The virtual network of claim 11 , wherein the coordinating network entity is further configured to:
assign a second multi-AP coordination scheme to a second dynamic group of network entities included in the virtual network, wherein the second dynamic group of network entities performs wireless communication based on the second multi-AP coordination scheme.

13 . The virtual network of claim 12 , wherein the first dynamic group of network entities does not include any of the same network entities included in the second dynamic group of network entities.

14 . The virtual network of claim 12 , wherein at least one network entity included in the first dynamic group of network entities is also included in the second dynamic group of network entities.

15 . The virtual network of claim 11 , wherein the at least one or more parameters comprise a link quality metric (LQM) table indicating at least one path loss value between two network entities included in the virtual network.

16 . The virtual network of claim 11 , wherein the at least one or more parameters comprises an uplink or downlink queue size of the at least one STA.

17 . The virtual network of claim 11 , wherein the first dynamic group of network entities are determined based on a network map of relative spatial configurations of one or more of the network entities included in the virtual network.

18 . The virtual network of claim 11 , wherein the coordinating network entity is further configured to:
assign a second multi-AP coordination scheme to the first dynamic group of network entities included in the virtual network in case that a value of the one or more parameters changes more than a predetermined threshold.

19 . The virtual network of claim 11 , wherein the coordinating network entity is included at least one of the plurality of APs.

20 . The virtual network of claim 11 , wherein the coordinating network entity is further configured to:
periodically receive an updated version of one or more of the parameters from the at least one AP included in the plurality of APs.
