Method and system for reducing forward link transmission power

摘要

This specification describes a method and corresponding system for reducing aggregate forward link transmission power. In one arrangement, a RAN may reduce the aggregate transmission power level in a coverage area by (i) determining which WCDs in the coverage area have a communication error rate that is at least a threshold level of communication error rate, and in response to the determining, (ii) reducing the forward link transmission power level of the determined WCDs. In another arrangement, the RAN may reduce the aggregate transmission power level in a coverage area by reducing the forward link transmission power of WCDs in the coverage area that have (i) a forward link transmission power level that is at least a threshold level of forward link transmission power and (ii) a communication error rate that is at least a threshold level of communication error rate.

1. In a wireless communication system in which a radio access network (RAN) serves one or more wireless communication devices (WCDs), each given WCD of the one or more WCDs having a respective forward link transmission power level at which the RAN transmits to the given WCD, a method comprising:
the RAN determining that a communication error rate of a particular WCD of the one or more WCDs is greater than a threshold level of communication error rate; and responsive to the determining, the RAN reducing the forward link transmission power level of the particular WCD.
