Methods for enhanced multiplexing in wireless systems
Methods and systems for operation in a wireless communication system are provided. A first transmission may be initiated using at least a first portion of physical layer resources. A second transmission may be initiated using at least a second portion of the same physical layer resources. The first transmission may be any one of a puncturing transmission, interfering transmission, delay-sensitive transmission, or short transmission. The second transmission may be an on-going transmission or a long 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 is unsuccessfully decoded;
sending a bitmap with code block group feedback based on the one or more unsuccessfully decoded code blocks;
receiving control information, on a control channel, wherein the control information includes an indication that a code block group of a second transmission is a retransmission of the code block group from the first transmission; and
receiving the second transmission including the retransmission of the code block group from the first transmission.
2. The method of claim 1 , wherein the control information further includes properties of the second transmission that identify the code block group of the second transmission.
3. The method of claim 2 , wherein the properties of the second transmission include an indication that the code block group of the retransmission is combinable with the code block group of the first transmission, and wherein the first transmission is received prior to the second transmission.
4. 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 is unsuccessfully decoded;
the transceiver and processor further configured to send a bitmap with code block group feedback based on the one or more unsuccessfully decoded code blocks; and
the transceiver and processor further configured to receive control information on a control channel and receive a second transmission including a retransmission of the code block group from the first transmission, wherein the control information includes an indication that a code block group of the second transmission is the retransmission of the code block group from the first transmission.
5. The WTRU of claim 4 , wherein the control information further includes properties of the second transmission that identify the code block of the second transmission.
6. The WTRU of claim 5 , wherein the properties of the second transmission include an indication that the code block group of the retransmission is combinable with the code block group of the first transmission, and wherein the first transmission is received prior to the second transmission.
7. 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 is unsuccessfully decoded;
receiving feedback including a bitmap with code block group feedback based on the one or more unsuccessfully decoded code blocks;
sending control information, on a control channel, wherein the control information includes an indication that a code block group of the second transmission is a retransmission of the code block group from the first transmission; and
sending the second transmission including the retransmission of the code block group from the first transmission.
8. The method of claim 7 , wherein the control information further includes properties of the second transmission that identify the code block group of the second transmission.
9. The method of claim 8 , wherein the properties of the second transmission include an indication that the code block group of the retransmission is combinable with the code block group of the first transmission, and wherein the first transmission is transmitted prior to the second transmission.
10. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
receiving a first transmission with a plurality of sets of code blocks, wherein each set of code blocks comprises a plurality of code blocks, and wherein one or more code blocks of a first set of code blocks of the plurality of sets of code blocks is unsuccessfully decoded;
sending a first transmission feedback bitmap based on the one or more unsuccessfully decoded code blocks, wherein each set of code blocks of the plurality of code blocks corresponds to a bit in the first transmission feedback bitmap; and
receiving control information, wherein the control information includes an indication that a second transmission will include a retransmission of the first set of code blocks.
