DYNAMIC CONTROL BLANKING IN HETEROGENEOUS NETWORKS

摘要

PROBLEM TO BE SOLVED: To blank control resources in heterogeneous network deployments.SOLUTION: An eNB, such as a macrocell, femtocell or picocell eNB, transmits a downlink control blanking message to a UE directing the UE to perform blanking or request the blanking from the interfering eNBs or devices. The downlink control blanking message can specify the desired control resources and/or information to determine the control resources. Dynamic control blanking is provided to mitigate interference over control resources for the small scale eNB. The small scale eNB can communicate control data to the UE over the control resources. The control data can include a resource blanking message that similarly directs the UE to request blanking of data resources from the interfering eNBs or devices.
