Title: JOINT OPTIMIZATION OF A RADIO ACCESS NETWORK AND A DISTRIBUTED ANTENNA SYSTEM
Abstract:
Certain features relate to systems and methods for jointly optimizing a radio access network (RAN) and distributed antenna system (DAS). A joint RAN-DAS self-optimizing network (SON) entity can determine target operations and management parameters based on operations and management parameters specific to the DAS and operations and management parameters specific to the RAN. The joint RAN-DAS-SON entity can optimize the RAN and DAS using the target operations and management parameters. Jointly optimizing the RAN and the DAS can improve the capacity characteristics, coverage characteristics, or the performance characteristics of the RAN and DAS. In some aspects, the joint RAN-DAS-SON entity can optimize the RAN and DAS by re-allocating power levels of downlink signals transmitted by remote units of the DAS to compensate for underutilized carrier signals in situations of low traffic load.
