Method and apparatus for dynamically adjusting a rise-over-thermal or noise rise threshold

摘要

Methods and apparatuses are provided that include adjusting rise-over-thermal (RoT) or noise rise (NR) threshold based on detecting interference from one or more devices. A device can communicate within close proximity of a femto node such that the device does not respond to power down commands from the femto node due to operating at a minimum transmit power. The device can cause the RoT or NR at the femto node to potentially rise over a threshold, however. Thus, the femto node can increase the RoT or NR threshold to allow the device to communicate with the femto node without impacting other devices communicating with the femto node. Out-of-cell interference from devices communicating with other base stations can be detected as well, and the RoT or NR threshold can be adjusted based thereon.

主权项

1. A method for adjusting a rise-over-thermal (RoT) or noise rise (NR) threshold, comprising:
communicating with one or more devices to provide network access; detecting a change in a level of interference caused by a signal from at least one device in the one or more devices, wherein detecting the change in the level of interference comprises detecting an increase in a received signal power of the signal received from the at least one device; determining that the at least one device transmits the signal at a minimum transmit power, wherein determining that the at least one device transmits the signal at a minimum transmit power comprises determining that the at least one device does not respond to one or more commands to decrease the power for transmitting the signal; and adjusting an RoT or NR threshold in proportion to the level of interference detected and based on the determination that the at least one device transmits the signal at a minimum transmit power.
