METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING A RADIO SIGNAL IN A WIRELESS COMMUNICATION SYSTEM Russian patent published in 2020 - IPC H04L1/18 H04L5/00 H04W28/10 H04W28/22 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to means for transmitting and receiving a radio signal in a wireless communication system. Data are received, including at least one CBG of the first transport unit (TB). In response to said data reception, corresponding HARQ-ACK information is transmitted for each of the plurality of CBGs of the first TB, including said at least one CBG included in said data. Said data reception relates to retransmission for a first TB. During said transmission of corresponding HARQ-ACK information in response to receiving data, wireless communication device generates only a positive receipt (ACK) as HARQ-ACK information for a specific CBG, which was successfully decoded at a previous reception for the first TB.

EFFECT: technical result is higher efficiency of transmitting and receiving a radio signal.
