Abstract
Methods for managing wireless backhaul in a multi-tier wireless local area network are disclosed. The methods comprise maintaining a polling list wherein the polling list specifies the children to be serviced, transmitting a communication in the downstream direction to a child in the polling list, receiving exception communications from the child, and updating the polling list in response to the exception communication.
Claims16
A method for managing wireless backhaul in a multi-tier wireless local area network comprising:
- in an access point in the multi-tier wireless local area network, wherein the multi-tier wireless local area network comprnses access points functioning as children and as parents;
- wherein a child sends communications in an upstream direction and receives communications from a downstream direction;
- and
- wherein a parent sends communications in a downstream direction and receives communications from an upstream direction;
- maintaining a polling list wherein the polling list specifies the children to be serviced;
- receiving exception communications from the child;
- and
- updating the polling list in response to an information in the exception communication.
A method for managing wireless backhaul in a multi-tier wireless local area network comprising:
- at a parent in the multi-tier wireless local area network:
- maintaining a polling list of children where the list specifies whether the child requires service from the parent;
- and
- broadcasting a beacon to children specifying a beacon interval for performing the following steps:
- (i) choosing a child from the polling list to service for a child duration;
- (ii) sending a downstream communication to the child;
- and
- (iii) receiving an upstream communication from a child;
- and
- (iv) performing exception processing to change the child duration;
- and
- (v) updating the polling list in response to exception processing.
A method for managing wireless backhaul in a multi-tier wireless local area network comprising:
- at a child in the multi-tier wireless local area network:
- receiving a beacon from a parent specifying a beacon interval;
- and
- performing the following steps during a child duration of the beacon interval:
- (i) receiving a downstream communication from the parent;
- and
- (ii) sending an upstream communication to the parent;
- and
- (iii) sending exception communications to the parent.
