METHOD, NETWORK NODES, AND COMPUTER PROGRAM PRODUCTS FOR LOAD BASED ADAPTIVE CRS POWER ADJUSTMENT

摘要

A method performed in a network node (302). The method includes the network node receiving (500) a report regarding a traffic load of at least one network cell of a plurality of network cells (304, 306). The method further includes the network node determining (404, 502) whether the traffic load of the at least one network cell is greater than an average traffic load of the plurality of network cells. The method further includes the network node adjusting (410, 414, 504) a power of a reference signal based on said determining. The method also includes the network node transmitting (506) the adjusted reference signal in the at least one network cell.
