Method and apparatuses for interference mitigation in a relay-based wireless network

摘要

A method for mitigating interference in a wireless communications network. Target nodes using a communications transmit node are identified, wherein a first group of target nodes is configured to communicate with the communications transmit node. A relay node using the communications transmit node is identified, wherein the relay node is configured to communicate with a second group of target nodes. The target nodes are classified into layers, wherein a first layer of target nodes is centrally scheduled and a second layer of target nodes is distributively scheduled. Centralized schedule information for the first layer of target nodes is determined. The centralized schedule information is transmitted to the relay node, wherein the relay node distributively schedules communications for the second layer of target nodes based at least in-part on the centralized schedule information, and wherein the relay node is configured to randomize a plurality of transmissions from the relay node.
