METHODS FOR ENHANCING MULTIPLEXING IN WIRELESS SYSTEMS
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.
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).
