METHOD AND DEVICE FOR FEEDBACK ON HYBRID AUTOMATIC REQUEST FOR RETRANSMISSION OF DATA Russian patent published in 2024 - IPC H04L1/16 

FIELD: wireless communication equipment.

SUBSTANCE: method of HARQ data bitmap information feedback includes receiving, by a terminal, indication information from an access network device, where the indication information is used to determine whether HARQ feedback is required for a transmission unit transmitted in a plurality of downlink transmission units. Terminal determines HARQ bitmap information based on indication information, where the HARQ bitmap information includes HARQ feedback information of at least one target transmission unit and the target transmission unit indicates the downlink transmission unit, which requires HARQ feedback in a plurality of downlink transmission units. Terminal sends HARQ bitmap information to the access network device.

EFFECT: reducing the size of the hybrid automatic repeat request (HARQ) bitmap, which leads to improved throughput and reduced communication delay.
