摘要： Methods and apparatuses are provided that include adaptively configuring a rise-over-thermal (RoT) threshold at a base station to improve communications with one or more devices while mitigating interference to one or more other base stations. A potential device pathloss to the macrocell can be computed based on a measured pathloss thereto applied with a coverage area of the low power base station to emulate a worst-case device, one or more received measurement reports, and/or the like. The RoT threshold can be computed based at least in part on the pathloss and/or a maximum interference level at the macrocell. In addition, the RoT threshold can be adapted based on a reverse link attenuation level.

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.

摘要： Transmit power for a user equipment (UE) is set by a Home NodeB (HNB) in response to interference at a nearby macrocell. The HNB monitors an interference level to the macrocell from a UE communicating with the HNB. An acceptable transmit power for the UE is determined by the HNB in response to the interference level. A power change indicator is transmitted from the HNB to the UE to adjust the transmit power of the UE. In some cases, the interference may be estimated from a busy indicator from the macrocell and the HNB sends a modified version of the busy indicator to the UE to adjust the transmit power of the UE. In other cases, the HNB estimates a path loss for the UE based on received signal power from the macrocell and signals a transmit power change to the UE, if needed, based on the estimated path loss.

摘要： A mobile station may include a standard transmit pulse-shaping filter, a standard receive pulse-shaping filter, a narrower transmit pulse-shaping filter, and a narrower receive pulse-shaping filter. A femtocell base station may include a narrower transmit pulse-shaping filter and a narrower receive pulse-shaping filter. The mobile station may utilize the narrower transmit pulse-shaping filter for transmitting uplink signals and the narrower receive pulse-shaping filter for receiving downlink signals when it is receiving service from the femtocell base station. The mobile station may utilize the standard transmit pulse-shaping filter for transmitting uplink signals and the standard receive pulse-shaping filter for receiving downlink signals when it is receiving service from a macrocell base station.

摘要： A method for reducing interference to wireless communication devices is described. It is determined that a base station is deployed with a first coverage area that overlaps a second coverage area of a femto access point. The base station uses a first carrier for wireless communications. The femto access point uses a second carrier for wireless communications. Transmissions by the femto access point interfere with transmissions by the base station. An amount of radio frequency (RF) leakage experienced by wireless communication devices communicating with the base station is estimated. Interference experienced by the wireless communication devices is minimized.
