US 2018/0323906 A1 · DATA TRANSMISSION WITH CODE BLOCK SEGMENTATION FOR 5G SYSTEMS

Abstract

Various embodiments disclosed herein provide for a transmission system using codeblock segmentation that does not have to retransmit each of the codeblock segments if one of the codeblock segments is determined to have an error at the receiver. The transmitter segments a transport block into a group of codeblock segments, each having respective cyclic redundancy check bits. The receiver receives the group of codeblock segments, and during decoding, if it is determined that one of the segments have an error, instead of just sending back to the transmitter a negative acknowledgement (NAK) the receiver can send back a NAK as well as an indicator of which segment was in error. The transmitter can then resend just the segment in error in order to improve efficiency and decrease power requirements.

Dependent claims

A base station device, comprising:

a processor;
and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
segmenting a transport block into a group of codeblock segments;
transmitting the group of codeblock segments to a receiver device;
receiving from the receiver device first information indicating that a codeblock segment of the group of codeblock segments received by the receiver device is in error, and second information indicating an identity of the codeblock segment of the group of codeblock segments that was in error;
and
retransmitting the codeblock segment to the receiver device.
