    Abstract: This document proposes soft activation and inactivation of (network) repeaters that are, for example, actuated on an as-needed basis. With soft activation, repeater gain ramps upward at controlled rate, thereby avoiding rapid changes in interference caused by the repeater. Likewise, with soft inactivation, repeater gain ramps downward at a controlled rate. Soft activation inactivation results in more gradual changes in the interference contribution of the repeater, thereby improving the performance of interference-compensating radio receivers operating in proximity to the repeater.

    Abstract: Delays on a common radio communications channel employed by plural mobile stations to communicate with a base station located in a corresponding geographical cell area are minimized by adapting transmission power based on traffic conditions. For lower traffic loads, a higher transmission power is permitted. For higher traffic loads, a lower power level is set. A transmit power level is determined using a desired signal ratio, such as a target CIR, a transmission path loss over the radio communications channel, and an interference value. One or more adaptive power parameters are also employed in that determination to adapt the open loop power control based on one or more current communications conditions and/or characteristics of the mobile station. For example, an adaptive power parameter may be a function of a current interference in a base station cell either alone or in combination with a current interference in one or more neighboring cells. The adaptive power parameter may also account for a type of data packet connection to be employed between a mobile station and the base station after random access, a mobile station's subscription, a current temperature of the mobile station, a current base station used by the mobile station, a current estimated path loss between the mobile station and base station, and/or other factors.

    Abstract translation: 通过根据交通状况调整发射功率,使多个移动台所采用的公共无线电通信信道上的延迟最小化,该基站位于相应的地理小区区域。 对于较低的交通负载,允许较高的发射功率。 对于较高的流量负载,设置较低的功率电平。 使用期望的信号比(例如目标CIR,无线电通信信道上的传输路径损耗)和干扰值来确定发射功率电平。 在该确定中还采用一个或多个自适应功率参数,以基于移动站的一个或多个当前通信条件和/或特性来适应开环功率控制。 例如,自适应功率参数可以单独地或与一个或多个相邻小区中的当前干扰组合在一起的基站小区中的当前干扰的函数。 自适应功率参数还可以考虑在随机接入之后在移动台和基站之间采用的数据分组连接的类型,移动台的订阅,移动台的当前温度,移动台使用的当前基站 站,移动台和基站之间的当前估计路径损耗和/或其他因素。
