1. Fremgangsmåde, der udføres afen netværksknude (110), til styring af effekt af CRS'er, Cell Reference Symbols, hvor netværksknuden (110) styrer en eller flere celler (130, 131, 132), og hvor netværksknuden (110) er konfigureret til at transmittere CRS'erne i en første effektmodus, hvilken fremgangsmåde omfatter: når en første celle (130) identificeres, hvilken første celle (130) ikke aktivt betjener nogen UE'er (120), at reducere (302) effekt af CRS'erne i den første celle (130) i forhold til den første effektmodus, kendetegnet ved, at fremgangsmåden yderligere omfatter at modtage (304), fra nabonetværksknuder (111), informationer om CRS- effektmodusen og antal aktivt betjente UE'er (120) i naboceller, at identificere (305), baseret på de modtagne informationer, en anden celle (131), hvilken celle (131) aktivt betjener mindst en UE (120) og grænser op til en celle (132), hvor antallet af aktivt betjente UE'er (120) overstiger en første tærskelværdi, når den anden celle (131) er blevet identificeret, at øge (306) effekten af CRS'erne i den anden celle (131) i forhold til den første effektmodus.
2. Fremgangsmåde ifølge krav 1, hvor den reducerede CRS-effekt anvendes på CRS'er, som sendes på et hvilket som helst OFDM (Orthogonal Frequency-Division Multiplexing)-symbol af en underramme, bortset fra underrammens første OFDM-symbol.
3. Fremgangsmåde ifølge et hvilket som helst af kravene 1-2, hvor fremgangsmåden yderligere omfatter: at sende (303) informationer om CRS-effekten og antallet af RRC-forbundne UE'er (120) til en eller flere nabonetværksknuder (111).
4. Fremgangsmåde ifølge krav 3, hvor informationerne sendes via en X2-grænseflade.
5. Fremgangsmåde ifølge et hvilket som helst af kravene 1-4, hvor reduktion og/eller øgning af CRS-effekten udføres under anvendelse af en hysterese-funktion.
6. Netværksknude (110) til udførelse af fremgangsmåden til styring af effekt af CRS'er, Cell Reference Symbols, hvor netværksknuden (110) styrer en eller flere celler (130, 131, 132), og netværksknuden (110) er konfigureret til at transmittere CRS'erne i en første effektmodus, hvilken netværksknude (110) yderligere er konfigureret til: at identificere en første celle (130), der ikke aktivt betjener nogen UE'er (120); og at reducere effekt af CRS'erne i den første celle (130) i relation til den første effektmodus, kendetegnet ved, at netværksknuden (110) yderligere er konfigureret til: at modtage, fra nabonetværksknuder (111), informationer om CRS-effektmodusen og antal aktivt betjente UE'er (120) i naboceller, at identificere en anden celle (131), hvilken celle (131) aktivt betjener mindst en UE (120) og grænser op til en celle (132), hvor antallet af aktivt betjente UE'er (120) overstiger en første tærskelværdi, at øge CRS-effekten i den anden celle (131) i forhold til den første effektmodus.
7. Netværksknude (110) ifølge krav 6, hvor netværksknuden (110) yderligere er konfigureret til: at sende informationer om CRS-effektmodusen og antallet af aktivt betjente UE'er (120) til en eller flere nabonetværksknuder (111).
8. Netværksknude (110) ifølge krav 7, hvor midlet til at sende informationer om CRS-effektmodusen og antallet af aktivt betjente UE'er (120) til nabonet- værksknuder (111) er en X2-grænseflade.
9. Netværksknude (110) ifølge et hvilket som helst af kravene 6-8, hvor netværksknuden (110) yderligere er konfigureret til: at reducere og/eller øge CRS-effekten under anvendelse af en hysterese-funktion.
