Abstract

A system and method of scheduling communication in a wireless communication network are provided. A first access node can determine a scheduling scheme based on data addressed to wireless devices in communication with the first, second, and third access nodes. The data addressed to the wireless devices in communication with the first access node can be transmitted during a first subframe of the scheduling scheme where the first access node does not transmit data addressed to the wireless devices in communication with the first access node during a second subframe of the scheduling scheme. The second and third access nodes can be instructed to assign data addressed to wireless devices that do not meet a signal condition threshold to be transmitted during the first subframe and to assign data addressed to wireless devices that meet the signal condition threshold to be transmitted during the second subframe.

Dependent claims

A method of scheduling communication in a wireless communication network, comprising:

determining at a first access node a scheduling scheme based on data addressed to wireless devices in communication with the first access node, data addressed to wireless devices in communication with a second access node, and data addressed to wireless devices in communication with a third access node, wherein the scheduling scheme comprises a first subframe and a second subframe;
communicating the scheduling scheme from the first access node to the second access node and the third access node;
transmitting the data addressed to the wireless devices in communication with the first access node during the first subframe of the scheduling scheme, wherein the first access node does not transmit data addressed to the wireless devices in communication with the first access node during the second subframe of the scheduling scheme;
instructing the second access node to assign data addressed to wireless devices in communication with the second access node that do not meet a signal condition threshold to be transmitted during the first subframe of the scheduling scheme and to assign data addressed to wireless devices in communication with the second access node that meet the signal condition threshold to be transmitted during the second subframe of the scheduling scheme, the signal condition threshold being met by wireless devices within a cell edge of one of the second and third access nodes;
instructing the third access node to assign data addressed to wireless devices in communication with the third access node that do not meet the signal condition threshold to be transmitted during the first subframe of the scheduling scheme and to assign data addressed to wireless devices in communication with the third access node that meet the signal condition threshold to be transmitted during the second subframe of the scheduling scheme;
and
receiving, at the first access node, an indication from the second access node that the data addressed to at least one wireless device that meets the signal condition threshold cannot be fully allocated during the second subframe;
wherein the indication is based on an application requirement of an application running on said at least one wireless device.

5 more elements

A system of scheduling communication in a wireless communication network, comprising:

a processing node configured to
determine a scheduling scheme based on data addressed to wireless devices in communication with a first access node, data addressed to wireless devices in communication with a second access node, and data addressed to wireless devices in communication with a third access node, wherein the scheduling scheme comprises a first subframe and a second subframe,
communicate the scheduling scheme from the first access node to the second access node and the third access node,
transmit the data addressed to the wireless devices in communication with the first access node during the first subframe of the scheduling scheme, wherein the first access node does not transmit data addressed to the wireless devices in communication with the first access node during the second subframe of the scheduling scheme,
instruct the second access node to assign data addressed to wireless devices in communication with the second access node that do not meet a signal condition threshold to be transmitted during the first subframe of the scheduling scheme and to assign data addressed to wireless devices in communication with the second access node that meet the signal condition threshold to be transmitted during the second subframe of the scheduling scheme, the signal condition threshold being met by wireless devices within a cell edge of one of the second and third access nodes;
instruct the third access node to assign data addressed to wireless devices in communication with the third access node that do not meet the signal condition threshold to be transmitted during the first subframe of the scheduling scheme and to assign data addressed to wireless devices in communication with the third access node that meet the signal condition threshold to be transmitted during the second subframe of the scheduling scheme;
and
receive, at the first access node, an indication from the second access node that the data addressed to at least one wireless device that meets the signal condition threshold cannot be fully allocated during the second subframe;
wherein the indication is based on an application requirement of an application running on said at least one wireless device.
