Configuration of uplink open loop power control parameters

Abstract

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 Po and α 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 Po and α, and/or adapted based on at least one of UE power headroom reports or overload indicators received from the neighbor cells.
