Abstract
A method for transmitting acknowledgement information by a user equipment (UE) in a wireless communication system, and an apparatus for supporting the same are disclosed. More particularly, a method for allowing a user equipment (UE) to transmit acknowledgement information for each code block group (CBG) with respect to data received within one or more slots is disclosed.
Claims20
A method for transmitting acknowledgement information by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving downlink control information scheduling 2 transmission blocks (TBs), each of the TBs including one or more code block groups (CBGs);
- receiving first downlink data related to the 2 TBs based on the downlink control information;
- and
- transmitting CBG level acknowledgement (ACK) information regarding (i) first ACK information related to a first TB in the received first downlink data and (ii) second ACK information related to a second TB in the received first downlink data,
- wherein the UE determines a size of a first payload for the first ACK information related to the first TB to be identical to a size of a second payload for the second ACK information related to the second TB.
A method for receiving acknowledgement information by a base station (BS) in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), downlink control information scheduling 2 transmission blocks (TBs), each of the TBs including one or more code block groups (CBGs);
- transmitting, to the UE, first downlink data related to the 2 TBs based on the downlink control information;
- and
- receiving, from the UE, CBG level acknowledgement information regarding (i) first ACK information related to a first TB in the first downlink data and (ii) second ACK information related to a second TB in the first downlink data,
- wherein a size of a first payload for the first ACK information related to the first TB is determined to be identical to a size of a second payload for the second ACK information related to the second TB.
A user equipment (UE) comprising:
- a transmitter;
- a receiver;
- and
- a processor operably connected to the transmitter and the receiver,
- wherein the processor is configured to:
- receive downlink control information scheduling 2 transmission blocks (TBs), each of the TBs comprising one or more code block groups (CBGs);
- receive first downlink data related to the 2 TBs based on the downlink control information;
- and
- transmit CBG level acknowledgement (ACK) information regarding (i) first ACK information related to a first TB in the received first downlink data and (ii) second ACK information related to a second TB in the received first downlink data,
- wherein the processor is further configured to determine a size of a first payload for the first ACK information related to the first TB to be identical to a size of a second payload for the second ACK information related to the second TB.
A base station (BS) comprising:
- a transmitter;
- a receiver;
- and
- a processor operably connected to the transmitter and the receiver,
- wherein the processor is configured to:
- transmit, to a user equipment (UE), downlink control information scheduling 2 transmission blocks (TBs), each of the TBs including one or more code block groups (CBGs);
- transmit, to the UE, first downlink data related to the 2 TBs based on the downlink control information;
- and
- receive, from the UE, CBG level acknowledgement information regarding (i) first ACK information related to a first TB in the first downlink data and (ii) second ACK information related to a second TB in the first downlink data,
- wherein a size of a first payload for the first ACK information related to the first TB is determined to be identical to a size of a second payload for the second ACK information related to the second TB.
