  • Patent number: 10763998
    Abstract: A method includes detecting (205), in a first communications apparatus, the number of failed code blocks in a transport block transmitted to the first apparatus from a second apparatus and a corresponding feedback size indicator. The feedback size indicator is received in the first apparatus from the second apparatus e.g. via control channel signalling. Alternatively, the feedback size indicator is received in the transport block. The first apparatus selects the format of a HARQ feedback message to be generated based on the feedback size indicator, and generates the feedback message based on the number of failed code blocks in the transport block. The generated feedback message is of the selected format and indicates the failed code blocks in the transport block. The first apparatus transmits the generated feed back message to the second apparatus.

  • Publication number: 20200153561
    Abstract: There are provided measures for flexible retransmission-process buffer management, such as e.g. flexible HARQ process buffer management, in the context of re-/transmission of a radio resource block composed of a plurality of resource block parts. Such measures exemplarily comprise buffer management and buffer management control, wherein a buffer element is flexibly managed by selectively discarding and keeping buffered soft data information of a transmitted radio resource block per resource block part based on decoding performance information for the buffered soft data information of the transmitted radio resource block prior to combining, per resource block part, soft data information of a retransmitted radio resource block with buffered soft data information of the transmitted radio resource block for decoding the radio resource block.

  • Patent number: 10498557
    Abstract: A signal modulated according to zero-tail discrete Fourier transform spread orthogonal frequency division multiplexing (ZT DFT-s-OFDM) is received over a channel. The signal is down-sampled into a first sequence including N samples, N corresponding to the number of used subcarriers. The first Nh samples and the last Nt samples are removed from the first sequence, thereby obtaining a second sequence having a length of N-Nh-Nt. The second sequence is correlated with a reference sequence which has a length N-Nh-Nt, and a frequency response of the channel is estimated over the N used subcarriers based on a result of the correlation.
