POWER SAVING IN A MULTIPLE SECTOR RADIO BASE STATION

摘要

A multiple sector RBS and a method therein for controlling the RBS is provided. The RBS is connectable to multiple sector antenna units supporting N sectors, N>=2, being associated with respective cell ids. The RBS comprises N Radio Units, RUs, serving the sectors. The method comprises transmitting (110) a respective cell id in each individual sector; deciding (115) that at least two individual sectors shall bemerged; deciding (120) which at least two sectors that shall be merged; and identifying their respective cell id. The method comprises determining (125) one cell id out of the identified at least two cell ids to be active, wherein the remaining cell id(s) to be passive; and transitioning (130), in each sector associated with a passive cell id, from transmitting the passive cell id to transmitting the active cell id. The method comprises switching off (135) RU(s) responsible for transmitting the passive cell ids.
