HARQ codebook structure

A user equipment for a radio access network, the user equipment comprising a processing circuitry connected to a memory and a radio circuitry, the radio circuitry comprising antenna circuitry, a receiver and transmitter or transceiver, the memory comprising instructions when executed by the processing circuitry causing the user equipment to:

• transmit, by the radio circuitry via the antenna circuitry, acknowledgement information reporting on subject transmissions associated to one or more subject transmission slots based on a HARQ codebook;
• the HARQ codebook indicating a bit pattern of the acknowledgement information;
• and
• the HARQ codebook being based on a first numerology, the first numerology being used for the subject transmissions in a first communication direction, and a second numerology, the second numerology being used for transmitting the acknowledgement information in a second communication direction, a first slot duration associated with the first numerology being different from a second slot duration associated with the second numerology.

A method of operating a signaling radio node in a radio access network, the method comprising:

• receiving, from a user equipment, acknowledgement information reporting on subject transmissions associated to one or more subject transmission slots based on a HARQ codebook;
• the HARQ codebook indicating a bit pattern of the acknowledgement information;
• and
• the HARQ codebook being based on a first numerology, the first numerology being used for the subject transmissions in a first communication direction, and a second numerology, the second numerology being used for transmitting the acknowledgement information in a second communication direction, a first slot duration associated with the first numerology being different from a second slot duration associated with the second numerology.

A signaling radio node for a radio access network, the signaling radio node comprising a processing circuitry connected to a memory and a radio circuitry, the radio circuitry comprising antenna circuitry, a receiver and transmitter or transceiver, the memory comprising instructions when executed by the processing circuitry causing the signaling radio node to:

• receive, by the radio circuitry via the antenna circuitry, from a user equipment, acknowledgement information reporting on subject transmissions associated to one or more subject transmission slots based on a HARQ codebook;
• the HARQ codebook indicating a bit pattern of the acknowledgement information;
• and
• the HARQ codebook being based on a first numerology, the first numerology being used for the subject transmissions in a first communication direction, and a second numerology, the second numerology being used for transmitting the acknowledgement information in a second communication direction, a first slot duration associated with the first numerology being different from a second slot duration associated with the second numerology.

A non-transitory computer storage medium storing computer program instructions that when executed on processing circuitry cause the processing circuitry to perform a method of operating a user equipment in a radio access network, the method comprising:

• transmitting acknowledgement information reporting on subject transmissions associated to one or more subject transmission slots based on a HARQ codebook;
• the HARQ codebook indicating a bit pattern of the acknowledgement information;
• and
• the HARQ codebook being based on a first numerology, the first numerology being used for the subject transmissions in a first communication direction, and a second numerology, the second numerology being used for transmitting the acknowledgement information in a second communication direction, a first slot duration associated with the first numerology being different from a second slot duration associated with the second numerology.
