Abstract

See full text

Various embodiments disclosed herein provide for a retransmission system that uses a hybrid system to signal to a receiver the retransmission of codeblock groups to reduce network overhead and bandwidth. The amount of bandwidth needed to signal to a receiver which codeblock groups are being retransmitted is directly proportional to the number of codeblock groups. Therefore, during retransmission, if the number of a codeblock groups is below a predetermined threshold, then explicit signaling can be performed, where the transmitter sends a bit map identifying the codeblock groups being retransmitted. If the number of codeblock groups is above the threshold however, can use a codeblock group confirmation bit in the control information sent to the receiver, where the values of the bit can inform the receiver how the retransmission will be performed.
