Coverage adjustment in E-UTRA networks
First Claim
1. One or more non-transitory computer readable media having program code that, when executed by one or more processors, causes a Coverage and Capacity Optimization (CCO) component to:
- receive service performance data of one or more evolved universal terrestrial radio access network (E-UTRAN) cells, wherein each E-UTRAN cell of the one or more E-UTRAN cells is provided by at least one evolved nodeB (eNB);
identify a service-deficient area based on the service performance data;
control transmission of a first instruction to initiate performance of one or more minimization of drive tests (MDTs) by one or more eNBs associated with the identified service-deficient area;
control receipt of MDT data that is based on results of the one or more MDTs;
correlate the MDT data with the service performance data;
determine a coverage area to be adjusted based on the correlation; and
control transmission of a second instruction to alter a service parameter of at least one E-UTRAN cell of the one or more E-UTRAN cells to adjust the coverage area.

Abstract
Embodiments of systems and techniques for coverage adjustment in evolved universal terrain radio access networks (E-UTRANs) are described. In some embodiments, a network management (NM) apparatus may receive data representative of first and second radio link failure (RLF) reports including information related to respective disconnections of first and second user equipment (UEs) from an E-UTRAN. The NM apparatus may identify a hole in a coverage area of the E-UTRAN based at least in part on the first and second RLF reports, and may perform an automated coverage and capacity optimization (CCO) action to reconfigure cell resources of the E-UTRAN based on the identified hole. Other embodiments may be described and claimed.
