Abstract:
A terrestrial cellular radio communication network (101) comprising at least a first base station (BS1), the first base station (BS1) comprising:radio signal generating means (401) adapted to generate a first set of low power radio signals (S11-S13) comprising at least a first radio signal (S11) and a second radio signal (S12); a power amplifying unit (402) adapted to generate a second set of amplified radio signals (S21-S23) corresponding to the first set of radio signals (S11-S13) by amplifying the first set of radio signals using a common set of multi carrier power amplifiers (409-412); an antenna system (403) adapted to radiate the second set of amplified radio signals (S21-S23) in associated antenna beams (417-419), the cellular radio communication network (101) further comprising: control means (440, 441) for controlling the set of radio carrier components included by the radio signal generating means (401) in each signal in the first set of radio signals (S11-S13), wherein the control means (440, 441) are adapted to instruct the radio signal generating means (401) to generate the first radio signal (S11) so as to consist of radio carrier components having frequencies allocated for use in a first cell (C1) of the cellular radio communication network (101) and the antenna system (403) is adapted to radiate the amplified radio signal (S21) corresponding to the first radio signal (S11) in an antenna beam (417) associated with the first cell (C1), characterized in that the control means (440, 441) are adapted to instruct the radio signal generating means (401) to generate the second radio signal (S12) so as to consist of radio carrier components having frequencies allocated for use in a second cell (C2) of the cellular radio communication network (101) and the antenna system (403) is adapted to radiate the amplified radio signal (S22) corresponding to the second radio signal (S12) in an antenna beam (418) associated with the second cell (C2).
