    1. Fremgangsmåde i en første kommunikationsanordning, der er en terminal, der opererer i TDD-tilstand, til modtagelse af kontrolinformationer og data over en radiokanal fra en anden kommunikationsanordning, der er en basisstation, der opererer i TDD-tilstand, omfattende trinnene med: modtagelse (C2) af en kontrolkanal i en downlink-subframe (DL1 - DL4) over radiokanalen, detektering (C4) af, hvorvidt downlink-subframen (DL1 - DL4) er en subframe med en downlink-ressourcetildeling, der er beregnet til den første kommunikationsanordning, og hvis en downlink-ressourcetildeling, der er beregnet til den første kommunikationsanordning, detekteres, dekodes de tilsvarende data, hvori den første kommunikationsanordning bundter bekræftelser eller ikke-bekræftelser fra alle modtagne downlink-subframes inden for en gruppe af downlink-subframes i en enkel uplink-subframe; kendetegnet ved når det detekteres, at en downlink-subframe (DL1-DL4) er en subframe med en downlink ressourcetildeling, der er beregnet til den første kommunikationsanordning, bestemmelse (C8), hvorvidt mindst én downlink-ressourcetildeling for data, der er sendt fra den anden kommunikationsanordning inden downlink-subframen (DL1-DL4), er tabt ved analyse af en indikator, der er forbundet med subframen; hvilken indikator tilvejebringer information om forudgående downlink-subframes med downlink-ressourcetildelinger, der er beregnet til den første kommunikationsanordning, hvilke informationer tilvejebringer viden om forudgående downlink ressourcetildelinger, der er beregnet til den første kommunikationsanordning; hvor den første kommunikationsanordning anvender en uplink-kontrolkanalressource, der er forbundet med den sidst detekterede downlink-ressourcetildeling i gruppen til transmission af de bundtede bekræftelser eller ikke-bekræftelser.
  2. 2. Fremgangsmåde i en anden kommunikations anordning, der er en basisstation, der opererer i TDD-tilstand, til transmission af kontrolinformationer og data over en radiokanal til en første kommunikationsanordning, der er en terminal, der opererer i TDD-tilstand, i en downlink-subframe med en downlink-ressourcetildeling, der er beregnet til den første kommunikationsanordning, omfattende trinnene med: tilføjelse (B2) af en indikator til downlink-subframen (DL1 - DL4), der tilvejebringer information om antallet af forudgående downlink-subframes med en downlink-ressourcetildeling, der er beregnet til den første kommunikationsanordning inden for en gruppe af downlink-subframes i kontrolinformationerne, og transmission (B4) af kontrolinformationerne og dataene på de tildelte ressourcer med downlink-subframen (DL1-DL4) til den første kommunikationsanordning, og modtagelse fra de første kommunikationsanordning bekræftelser eller ikke-bekræftelser fra alle downlink-subframes, der er modtaget af den første kommunikationsindretning inden for gruppen af downlink-subframes, der er bundtet i en enkelt uplink-subframe; hvor den anden kommunikationsanordning lytter til en uplink-kontrolkanalressource, der er forbundet med den sidste downlink ressourcetildeling i gruppen af downlink-subframes og tager passende handling, hvis den detekterer, at intet blev transmitteret på denne uplink-kontrolkanalressource.
