METHOD FOR ENHANCED HARQ-ACK FEEDBACK IN WIRELESS COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17441680 titled 'METHOD FOR ENHANCED HARQ-ACK FEEDBACK IN WIRELESS COMMUNICATIONS
Simplified Explanation
The patent application describes a method to improve Hybrid Automatic Repeat Request (HARQ)-ACK in a 5G wireless communications system.
- HARQ-ACK is a mechanism used in wireless communication to acknowledge the successful reception of data packets.
- In 5G systems, a user equipment (UE) can receive either a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission during a HARQ-ACK window.
- The UE generates a HARQ-ACK information bit based on the received transmission.
- The UE is configured with an offset value (k) and a length (l) of the HARQ-ACK window associated with an uplink transmission slot (n) of a Physical Uplink Control Channel (PUCCH) transmission.
- The starting slot of the HARQ-ACK window is determined as n−k.
- If a valid uplink transmission slot is not available, the UE transmits the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.
Original Abstract Submitted
Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n−k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.
