Abstract

Methods and systems for operation in a wireless communication system are provided. A WTRU may receive a first transmission of a code block group where one or more code blocks of the code block group are unsuccessfully decoded. The WTRU sends in a bitmap, code block group feedback based on the one or more code blocks of the code block group unsuccessfully decoded and receives control information for a second transmission, in a control channel transmission, where the control information includes an indication that the code block group is in the second transmission, and where the control information includes a new data indicator indicating whether the code block group in the second transmission is for retransmission. The WTRU may then receive the second transmission.

Claims (24)

1 . A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:

receiving a first transmission of a code block group, wherein one or more code blocks of the code block group are unsuccessfully decoded;

sending, in a bitmap, code block group feedback based on the one or more code blocks of the code block group unsuccessfully decoded;

receiving control information for a second transmission, in a control channel transmission, wherein the control information includes an indication that the code block group is in the second transmission, and wherein the control information includes a new data indicator indicating whether the code block group in the second transmission is for retransmission; and

receiving the second transmission.

2 . The method of claim 1 , wherein the first transmission is received prior to the second transmission.

3 . The method of claim 1 , wherein the code block group feedback is Hybrid Automatic Repeat Request (HARQ) feedback.

4 . The method of claim 1 , wherein the control information is downlink control information (DCI).

5 . A wireless transmit/receive unit (WTRU), the WTRU comprising:

a transceiver operatively connected to a processor, the transceiver and processor configured to receive a first transmission of a code block group, wherein one or more code blocks of the code block group are unsuccessfully decoded;

the transceiver and the processor further configured to send, in a bitmap, code block group feedback based on the one or more code blocks of the code block group unsuccessfully decoded;

the transceiver and the processor further configured to receive control information for a second transmission, in a control channel transmission, wherein the control information includes an indication that the code block group is in the second transmission, and wherein the control information includes a new data indicator indicating whether the code block group in the second transmission is for retransmission; and

the transceiver and the processor further configured to receive the second transmission.

6 . The WTRU of claim 5 , wherein the first transmission is received prior to the second transmission.

7 . The WTRU of claim 5 , wherein the code block group feedback is Hybrid Automatic Repeat Request (HARQ) feedback.

8 . The WTRU of claim 5 , wherein the control information is downlink control information (DCI).

9 . A method implemented by a base station, the method comprising:

sending a first transmission of a code block group, wherein one or more code blocks of the code block group are unsuccessfully decoded;

receiving a bitmap with code block group feedback based on the one or more code blocks of the code block group unsuccessfully decoded;

sending control information for a second transmission, in a control channel transmission, wherein the control information includes an indication that the code block group is in the second transmission, and wherein the control information includes a new data indicator indicating whether the code block group in the second transmission is for retransmission of the code block group; and

sending the second transmission.

10 . The method of claim 9 , wherein the first transmission is transmitted prior to the second transmission.

11 . The method of claim 9 , wherein the code block group feedback is Hybrid Automatic Repeat Request (HARQ) feedback.

12 . The method of claim 9 , wherein the control information is downlink control information (DCI).
