Interference management and network performance optimization in small cells

摘要

A method of configuring small cell base stations in a cellular network is disclosed. A constraint on a performance-related metric associated with at least a portion of the cellular network is received. In some embodiments, the constraint on the performance-related metric comprises a constraint on a performance-related metric associated with one or more macrocells. Measurement data from one or more small cell base stations is received via a control interface. One or more optimized values of one or more parameters associated with one or more small cell base stations are searched. The searching is based at least in part on the received measurement data and subject to the constraint on the performance-related metric associated with the at least a portion of the cellular network. The one or more optimized values of the one or more parameters to the associated small cell base stations are transmitted.

1. A method of configuring small cell base stations in a cellular network, comprising:
receiving a constraint on a performance-related metric associated with at least a portion of the cellular network; receiving measurement data from one or more small cell base stations via a control interface; searching, using a processor, for one or more optimized values of one or more parameters associated with one or more small cell base stations, wherein the searching is based at least in part on the received measurement data and subject to the constraint on the performance-related metric associated with the at least a portion of the cellular network, wherein the one or more parameters comprise a parameter corresponding to a cell range extension bias towards a small cell base station, and wherein the searching optimizes the parameter corresponding to the cell range extension bias based on whether the small cell base station is integrated with or co-located with a Wi-Fi access point; and transmitting the one or more optimized values of the one or more parameters to the associated small cell base stations.
