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 be merged; 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.

1. A method in a multiple sector Radio Base Station, RBS, for controlling the RBS, the RBS being connectable to multiple sector antenna units supporting N sectors, where N≧2, the sectors being associated with respective cell identities, ids, the RBS comprising N Radio Units, RUs, serving said sectors, the method comprising:
transmitting, by means of a RU, in each individual sector, a respective cell id associated with the individual sector, deciding that at least two individual sectors shall be merged, and deciding which at least two sectors out of the N sectors that shall be merged and further identifying the respective cell id of the at least two sectors; determining one cell id out of the identified at least two cell ids that shall be active, wherein the remaining cell id(s) out of the identified cell ids shall be passive, transitioning, in each sector associated with a cell id that shall be passive, from transmitting the cell id that shall be passive to transmitting the cell id that shall be active, and switching off RU(s) responsible for transmitting the cell ids which has become passive when a transmission power for transmitting those cell id(s) has reached a threshold power value.
