Abstract:

The present disclosure relates to methods of transmitting and receiving transmission feedback. More particularly the disclosure pertains to transmitting and receiving messages acknowledging reception and successful decoding of a transport block in a radio network node. The disclosure also relates to a wireless device providing transmission feedback and to a radio network node receiving the transmission feedback. A radio network node transmits using a set of transmission properties, a first sequence of two or more transport blocks to a receiving wireless device, wherein the transmitting is performed without waiting for acknowledgement or non-acknowledgement (ACK/NACK) feedback in-between transport block transmissions, and wherein each of the transport blocks in the first sequence relates to a same packet. The radio network node receives, from the receiving wireless device, the ACK/NACK feedback, indicating reception and decoding outcome of the transport block sequence in the receiving wireless device, wherein the ACK/NACK feedback defines a decoding margin of the decoding. The disclosure also proposes a corresponding wireless device and corresponding methods as well as a corresponding computer program.
