Abstract

In a radio access network in which a first access terminal uses a first access point to access the network and a second access terminal uses a second access point to access the network, interference is reduced in communications between the first access terminal and the first access point by adjusting signal power levels of the second access terminal without requiring coordination between the first and second access points.
