Method and apparatus for mitigating interference in femtocell deployments

摘要

Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.

主权项

1. A method for adjusting parameters of a femtocell access point, comprising:
detecting a strongest downlink transmit power of one or more access points, wherein the strongest downlink transmit power is detected based on measuring one or more signals received from the one or more access points; determining whether the strongest downlink transmit power exceeds a downlink transmit power of the femtocell access point; and adjusting an estimated noise floor of the femtocell access point based at least in part on whether the strongest downlink transmit power exceeds the downlink transmit power of the femtocell access point.
