摘要：
A method or apparatus for configuring OLPC parameters for uplink communications in a cellular wireless network includes determining an estimated number of neighbor cells deployed within radio range of a cell, and configuring OLPC parameters for uplink communications, based on the estimated number of neighbor cells. Determining the estimated number of neighbor cells may include measuring respective signal strengths of the neighbor cells using network listen functionality. At least two OLPC intermediate parameters P0 and a may be selected from a data table, based on the estimated number of neighbor cells. A path loss statistic may be determined, based on UE measurement reports including path losses of UEs to itself and other cells. The OLPC parameters may be selected based on the path loss statistic and P0 and a, and/or adapted based on at least one of UE power headroom reports or overload indicators received from the neighbor cells.
摘要（中）：
用于配置蜂窝无线网络中的上行链路通信的OLPC参数的方法或装置包括基于所估计的相邻小区数来确定在小区的无线电范围内部署的相邻小区的估计数量，以及配置用于上行链路通信的OLPC参数。 确定相邻小区的估计数量可以包括使用网络侦听功能测量相邻小区的相应信号强度。 可以基于估计的相邻小区数从数据表中选择至少两个OLPC中间参数P0和a。 基于UE测量报告，包括UE自身和其他小区的路径损耗，可以确定路径损耗统计量。 OLPC参数可以基于路径损耗统计和P0和a选择，和/或基于从相邻小区接收的UE功率余量报告或过载指示符中的至少一个来选择。
