Abstract
Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for transmitting uplink control information in new radio (NR) applications. Various embodiments describe how to calculate a number of reserved HARQ-ACK resource elements. Other embodiments may be described and claimed.
Claims25
One or more non-transitory, computer-readable media having instructions that, when executed, cause a user equipment (UE) to:
- identify a fixed hybrid automatic repeat request-acknowledgement (HARQ-ACK) payload size;
- calculate, based on the fixed HARQ-ACK payload size, a number of reserved HARQ-ACK resource elements (REs) to carry one or more HARQ-ACK bits of a HARQ-ACK;
- and
- map the number of reserved HARQ-ACK REs on resources allocated for physical uplink shared channel (PUSCH) transmission.
One or more non-transitory, computer-readable media having instructions that, when executed, cause a user equipment (UE) to:
- calculate a number of reserved hybrid automatic repeat request-acknowledgment (HARQ-ACK) resource elements (REs) to be mapped onto a symbol of a physical uplink shared channel (PUSCH);
- and
- map, based on a mapping rule, the number of reserved HARQ-ACK resource elements onto the symbol,
- wherein a distance between adjacent resource elements of the number of reserved HARQ-ACK resource elements mapped onto the symbol is one if the number of reserved HARQ-ACK resource elements is equal to or larger than a number of available resource elements in the symbol.
An apparatus comprising:
- memory circuitry to store one or more hybrid automatic repeat request-acknowledgment (HARQ-ACK) bits;
- processing circuitry coupled with the memory circuitry, the processing circuitry to:
- identify a fixed HARQ-ACK payload size;
- calculate, based on the fixed HARQ-ACK payload size, a number of reserved HARQ-ACK resource elements (REs) to carry the one or more HARQ-ACK bits;
- encode the one or more HARQ-ACK bits in the number of reserved HARQ-ACK resource elements;
- and
- map the number of HARQ-ACK REs onto resources allocated for physical uplink shared channel (PUSCH) transmission.
