US 2017/0289922 A1 · Method and Network Node for Obtaining Nominal Power and Pathloss Compensation Factor of a Power Control Process

Abstract

A method and a network node (110) for obtaining a nominal power “P0” of transmissions on an uplink channel and a pathloss compensation factor “α” are disclosed. The cell (101) is associated to a non-regular scenario, at least network node partly defined by respective locations of further cells of the cellular network (100). The further cells are neighbours to the cell (101), which is located at a location within the cellular network (100). The network node (110) generates, for each further cell, a respective regular scenario in relation to the cell (101). The generation is at least based the respective location corresponding to said each further cell and the location of the cell (101). The network node (110) determines, also for each further cell, a respective P0 and a respective α for each respective regular scenario. The network node (110) applies a statistical formula to each of the respective P0 and the respective α to obtain the nominal power and the path loss compensation factor to be applied by the user equipment (120) in the cell (101).
