A system and method for dynamically optimizing the performance of indoor distributed antenna systems communicate to user equipment is disclosed. The user equipment measures information describing the downlink signals such as the downlink data rates, the quality of the received signal, and the location of the user equipment. A service module collects this information and determines an optimized power level for each of the antenna units. The service module may optimize only one antenna unit power level or a subset of the antenna units within the distributed antenna system in a preferred embodiment. One or more of the antenna units then transmits downlink signals with the optimized power levels. The optimized power level may be less than the initial power level in a preferred embodiment. As a result, the performance of the indoor distributed antenna systems is enhanced.

Apparatus for distributed antenna system with downlink transmission power control

A system and method for enhancing the performance in heterogeneous wireless access networks employing a distributed antenna system is disclosed. A control unit comprises a distributed antenna system management server which collects load information from each of the carriers. The control unit further comprises a power management decision engine which determines the optimal downlink transmission power level for the carriers based on the collected load information and a set of parameters related to the power for the carriers. Power levels may decrease to baseline parameters when the load on carriers decreases.

System and method for performance enhancement in heterogeneous wireless access network employing distributed antenna system

A system and method for dynamically optimizing the transmission power levels for downlink voice and data signal transmitted from a base station to user equipment is disclosed. The user equipment measures the strength and quality of the downlink signal, and transmits this downlink signal information to a control unit. The control unit analyzes the downlink information and employs an adaptive self-learning traffic algorithm which determines optimized power levels for the downlink signals. The control unit may optimize only one carrier signal or a subset of the multi-carrier signals in a preferred embodiment. The values of the optimized power levels are sent to the base station which then increases or decreases the downlink transmission power of one or more carrier signals based on this level. As a result, the area associated with dead spots is reduced and the quality of the downlink signals is enhanced.
