Preemption indicators and code-block-group-based retransmission techniques for multiplexing different services on physical layer frames
Techniques are disclosed relating to acknowledgements and preemption indicators in the context of multiplexing different services on wireless physical layer frames. In some embodiments, transport blocks for a transmission are divided into code blocks and code block groups. Information indicating the division may be communicated between a base station and mobile device. In some embodiments, a preemption indicator is transmitted which indicates a portion of the transport block preempted by another data service, and the preemption indicator is specified at a different granularity than a code block group. In some embodiments, acknowledgement information is transmitted that indicates, for each code block group included in the transport block, whether the code block group was successfully decoded by the user device. In various embodiments, the disclosed techniques may facilitate preemption by a low-latency, high-reliability data service.
