Embodiment Construction

[0021] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description contains specific details for the purpose of providing a thorough understanding of various concepts. However, one skilled in the art would understand that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring the concepts.

[0022] Various aspects of this disclosure provide techniques to mitigate interference problems between wireless network devices. As mentioned above, an evolved Node B (eNodeB) may experience high cell load or high interference. An eNodeB that is experiencing higher cell load or serving user equipment (UE) under higher interference will generally request th...

Abstract

Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering / aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes.

Description

[0001] Information about divisional applications [0002] This application is a divisional application. The parent case of this divisional application is an invention patent application with an application date of June 28, 2011, an application number of 201180037881.9, and an invention title of "Measurement of Resource Utilization Rate for Heterogeneous Networks". technical field [0003] Aspects of the invention relate generally to wireless communication systems, and more particularly to resource utilization measurements for heterogeneous networks. Background technique [0004] A wireless communication network may contain a number of base stations that can support communication for a number of user equipments (UEs). A UE can communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base statio...
