HARQ codebook structure

A user equipment for a radio access network, the user equipment comprising processing circuitry being configured to cause the user equipment to:

• transmit acknowledgement information reporting on subject transmissions based on a HARQ codebook;
• and
• the HARQ codebook indicating a bit pattern of the acknowledgement information, the bit pattern having a plurality of subpatterns, each subpattern being associated to a different subdivision of a reception time interval to which the acknowledgement information pertains, and each subpattern having a predetermined number of bits of acknowledgement information associated to subject transmissions of the subdivision, a size of at least one subpattern of the plurality of patterns being configured semi-statically.

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 based on a HARQ codebook;
• and
• the HARQ codebook indicating a bit pattern of the acknowledgement information, the bit pattern having a plurality of subpatterns, each subpattern being associated to a different subdivision of a reception time interval to which the acknowledgement information pertains, and each subpattern having a predetermined number of bits of acknowledgement information associated to subject transmissions of the subdivision, a size of at least one subpattern of the plurality of patterns being configured semi-statically.

A signaling radio node for a radio access network, the signaling radio node comprising processing circuitry being configured to cause the signaling radio node to:

• and
• the HARQ codebook indicating a bit pattern of the acknowledgement information, the bit pattern having a plurality of subpatterns, each subpattern being associated to a different subdivision of a reception time interval to which the acknowledgement information pertains, and each subpattern having a predetermined number of bits of acknowledgement information associated to subject transmissions of the subdivision, a size of at least one subpattern of the plurality of patterns being configured semi-statically.

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

• transmitting acknowledgement information reporting on subject transmissions based on a HARQ codebook;
• and
• the HARQ codebook indicating a bit pattern of the acknowledgement information, the bit pattern having a plurality of subpatterns, each subpattern being associated to a different subdivision of a reception time interval to which the acknowledgement information pertains, and each subpattern having a predetermined number of bits of acknowledgement information associated to subject transmissions of the subdivision, a size of at least one subpattern of the plurality of patterns being configured semi-statically.
