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： Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.
摘要翻译：可以通过自适应路径损耗调整的确定和应用来管理在无线通信期间发生的干扰。通信的方法，装置和介质至少部分地基于小区外干扰（Ioc）来确定多余的接收干扰的水平。当超出接收干扰的电平超过会导致上升热（RoT）度量超过稳定通信的干扰目标时，路径损耗由上行链路信号上的附加路径损耗来调整。

摘要： A femtocell base station includes a transmitter that transmits downlink signals to a mobile station, a receiver that receives uplink signals from the mobile station, a standard transmit pulse-shaping filter, and a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals to a greater extent than the standard transmit pulse-shaping filter. The femtocell base station also includes a standard receive pulse-shaping filter and a narrower receive pulse-shaping filter. The femtocell base station is configured to switch between the standard transmit pulse-shaping filter and the narrower transmit pulse-shaping filter, and to switch between the standard receive pulse-shaping filter and the narrower receive pulse-shaping filter. A mobile station may switch from a standard transmit pulse-shaping filter to a narrower transmit pulse-shaping filter to limit uplink interference. A mobile station may switch from a narrower transmit pulse-shaping filter to a standard transmit pulse-shaping filter to achieve a higher data rate.

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.
摘要翻译：提供了包括基于检测来自一个或多个设备的干扰来调整上升热（RoT）或噪声上升（NR）阈值的方法和装置。设备可以在毫微微节点的非常接近的范围内通信，使得设备由于以最小的发射功率运行而不响应来自毫微微节点的掉电命令。然而，该设备可能导致毫微微节点处的RoT或NR潜在地超过阈值。因此，毫微微节点可以增加RoT或NR阈值，以允许设备与毫微微节点通信，而不影响与毫微微节点通信的其他设备。也可以检测来自与其他基站通信的设备的小区外干扰，并且可以基于此来调整RoT或NR阈值。

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： Transmissions of beacons by a set of access points (e.g., femtocells) are synchronized to facilitate discovery of the access points by an access terminal moving through the coverage areas of the access points. In some embodiments, periodic beacon transmissions are synchronized across all of the femtocells of a set of femtocells such that each femtocell transmits a beacon signal according to a similar pattern and at the same time. In some embodiments, an opportunistic beacon control scheme involves commencing beacon transmissions by at least one femtocell of a set of femtocells upon determining that an access terminal has communicated with one or more of the femtocells.
