摘要： A method is provided for dynamically updating the fractional power control (FPC) parameters of a wireless network such as an LTE network, so that system performance can be improved in a variety of different loading conditions, particularly under conditions of moderate or light loading. An exemplary embodiment includes obtaining a current value of a time-varying uplink interference figure for at least one individual sector s. For at least one such sector s, a value is selected for at least one FPC parameter, thereby to determine a dependency of the target SINR {circumflex over (γ)}(k,s) on the path loss λ(k,s) for each UE k in sector s for which {circumflex over (γ)}(k,s) falls between a maximum target {circumflex over (γ)}max and a minimum target {circumflex over (γ)}min. The selecting step is responsive to the obtained interference figure, such that at least one FPC parameter.

摘要： Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the system and a linear sum of the signal-to-noise measures. The signal-to-noise measures may be generated in the mobile station and included in messages transmitted from the mobile station to one or more base stations of the system. The trigger metric is used to control a handoff from a current frequency to a new frequency in an ongoing call. The trigger metric may alternatively be based on a measure of mobile receive power alone. Other aspects of the invention reduce unnecessary searching for a new frequency and decrease the likelihood of “ping-ponging” from a current frequency to a new frequency by providing additional checks in the handoff process. For example, receive power and pilot signal-to-noise measures may be generated at a mobile station for both current and new frequencies. The mobile station then continues to operate at the current frequency as long as certain predetermined threshold conditions based on the measures are satisfied.

摘要翻译： CDMA或其他无线通信系统中的频率间切换是使用能够区分系统中的同频小区边界和其它频率小区边界的噪声限制覆盖触发度量来控制的。可以根据在系统的移动台处接收的导频信号的平均信噪比测量值和信噪比测量的线性和来产生触发度量。信号噪声测量可以在移动台中产生，并且包括在从移动站发送到系统的一个或多个基站的消息中。触发度量用于控制正在进行的呼叫中从当前频率到新频率的切换。触发度量可以替代地基于单独的移动接收功率的量度。本发明的其他方面通过在切换过程中提供额外的检查来减少对新频率的不必要的搜索并且减少从当前频率到新频率的“乒乓”的可能性。例如，可以在移动台处为当前和新频率产生接收功率和导频信号噪声测量。只要满足基于措施的某些预定阈值条件，移动台就继续以当前频率工作。

摘要： A method and system that minimizes pilot signal overlap and radio frequency (“RF”) interference by estimating changes in pilot coverage for different traffic channel loading and power conditions. Once base stations are positioned, a terminal for measuring received pilot signal strengths, such as a mobile station or pilot scanner, is used to collect and generate the baseline pilot survey data, which is then stored on a disk or tape. Base station transmit pilot EC/IOs, i.e., traffic channel loads on forward links, are also stored on disk or tape. The invention uses two adjustment factors associated with transmit power and traffic channel loading to optimize for different RF conditions, specifically for different base station transmit power or forward link loading conditions. For each RF condition, the methodology calculates the changes in the baseline pilot survey data. This reflects what EC/IOs a mobile station would receive under the given conditions. The systems engineer collects a set of optimized base station power settings for each of the different traffic channel load conditions. One of these optimized power settings is then selected by the systems engineer for each of the base stations.
