Claims (8)
1. Fremgangsmåde til en indretning i en basisstation (110) til behandling af en bekræftelses-/negativbekræftelses-"ACK"/"NAK"-besked fra en terminal (120), hvor basisstationen (110) og terminalen (120) omfattes af et telekommunikationssystem, hvor fremgangsmåden omfatter de følgende trin: at sende (801) et antal downlink-underrammer, som omfatter transportblokke, til terminalen (120), at signalere (804) i hver underramme Downlink Assignment Index "DAI" til terminalen (120), hvor DAI repræsenterer antallet af tidligere downlink-underrammer, hvor en downlink-overdragelse er addresseret til terminalen, hvilket DAI vil blive anvendt af terminalen (120) til at konstatere, om en hvilken som helst downlink-underramme, der overføres fra basisstationen (110), har manglet ved at sammenligne antallet af modtagne downlink-overdragelser med DAI, der er signaleret fra basisstationen (110), at modtage (802) fra terminalen (120) én kodet ACK-besked til /cdownlink-overdragelser, hvor den kodede ACK-besked omfatter k, antallet af underrammer, i hvilke en downlink-overdragelse, som blev adresseret til terminalen, blev detekteret af terminalen (120), hvis hver af transportblokkene, der omfattes af downlink-underrammerne, hvor der detekteres en downlink-overdragelse, vurderes som korrekt modtaget af terminalen (120), at modtage (607) fra terminalen (120) én kodet NAK-besked, hvor den kodede NAK-besked moduleres til et konstellationspunkt, der er forskellig fra det konstellationspunkt, som ville have været brugt til modulering af ACK-beskeden, hvis en downlink-overdragelse, der blev sendt fra basisstationen (110) til terminalen (120), er blevet konstateret at være manglende af terminalen (120).
2. Fremgangsmåde ifølge krav 1, hvor flere PSK-konstellationspunkter anvendes til PSK-modulering i den modtagne ACK/NAK-besked, og hvor et første konstellationspunkt (NAK) af de flere PSK-konstellationspunkter anvendes til den kodede NAK-besked, og forskellige anden konstellationspunkter (ACK1, ACK2, ACK3, ACK4) af de flere PSK-konstellationspunkter anvendes til den kodede ACK-besked til forskellige værdier af k, hvor de forskellige anden konstellationspunkter (ACK1, ACK2, ACK3, ACK4) alle er forskellige fra det første konstellationspunkt (NAK), og hvor udvalgte konstellationspunkter afhænger af antallet k.
3. Fremgangsmåde ifølge et hvilket som helst af kravene 1-2, hvor ensartet Phase-Shift Keying "PSK" anvendes til modulering af den kodede ACK-besked til /c-underrammer, eller NAK-besked, eller DTX-besked til et PSK-konstellationspunkt.
4. Fremgangsmåde ifølge krav 3, hvor Quadrature Phase Shift Keying "QPSK" anvendes til den respektive kodede ACK-besked til k downlink-overdragelser, eller NAK-besked, eller DTX-besked, der sendes fra terminalen (120).
5. Fremgangsmåde ifølge krav 4, hvor QPSK anvendes, omfattende et første QPSK-konstellationspunkt, et andet QPSK-konstellationspunkt, et tredje QPSK-konstellationspunkt og et fjerde QPSK-konstellationspunkt, hvor det første konstellationspunkt anvendes til modulering i den kodede NAK-besked, hvor det andet konstellationspunkt anvendes til modulering i den kodede ACK-besked til kdownlink-overdragelser, når k= 1 eller 4, hvor det tredje konstellationspunkt anvendes til modulering i den kodede ACK-besked til kdownlink-overdragelser, når k= 2, og hvor det fjerde konstellationspunkt anvendes til modulering i den kodede ACK-besked til kdownlink-overdragelser, når k= 3.
6. Fremgangsmåde ifølge et hvilket som helst af kravene 1-2, hvor X-QAM anvendes til modulering af den kodede ACK-besked til k downlink-overdragelser, eller NAK-besked, eller DTX-besked til et X-QAM-konstellationspunkt, hvor X kan antage en hvilken som helst af 2Λ2, 2Λ3, 2Λ4,...2ΛΝ.
7. Fremgangsmåde ifølge et hvilket som helst af kravene 1-2, hvor ikke-ensartet PSK anvendes til modulering af den kodede ACK-besked til k down-link-overdragelser, eller NAK-besked, eller DTX-besked til et PSK-konstellationspunkt.
8. Indretning (900) til en basisstation (110), til håndtering af en bekræftelses-/negativbekræftelses-"ACK"/"NAK"-besked fra en terminal (120), hvor basisstationen (110) og terminalen (120) omfattes af telekommunikationssystem, hvor basisstationsindretningen (900) omfatter: en sendeenhed (910), der er konfigureret til at sende et antal downlink-underrammer, som omfatter transportblokke, til terminalen (120), hvor sendeenheden (910) endvidere er konfigureret til at signalere i hver underramme Downlink Assignment Index "DAI" til terminalen (120), hvor DAI repræsenterer antallet af tidligere downlink-underrammer, hvor en downlink-overdragelse er addresseret til terminalen, hvilket DAI vil blive anvendt af terminalen (120) til at konstatere, om en hvilken som helst downlink-underramme, der overføres fra basisstationen (110), har manglet ved at sammenligne antallet af modtagne downlink-overdragelser med DAI, der er signaleret fra basisstationerne (110), en modtageenhed (920), der er konfigureret til at modtage fra terminalen (120) én kodet ACK-besked til k downlink-overdragelser, hvor den kodede ACK-besked omfatter k, antallet af underrammer, i hvilke en downlink-overdragelse, som blev adresseret til terminalen, blev detekteret af terminalen (120), hvis hver af transportblokkene, der omfattes af downlink-underrammerne, hvor der detekteres en downlink-overdragelse, vurderes som korrekt modtaget af terminalen (120), og modtageenheden (920) endvidere er konfigureret til at modtage fra terminalen (120) én kodet NAK-besked, hvor den kodede NAK-besked moduleres til et konstellationspunkt, der er forskellig fra det konstellationspunkt, som ville have blevet anvendt til modulering af ACK-beskeden, hvis en downlink-overdragelse, der blev sendt fra basisstationen (110) til terminalen (120), er blevet konstateret at være manglende af terminalen (120).
