Preemption indicator and code block group based retransmission technique for multiplexing different services on physical layer frame

摘要

Techniques for acknowledgments and preemption indicators in the context of multiplexing different services on a radio physical layer frame are disclosed. In some embodiments, transport blocks for transmission are divided into code blocks and code block groups. Information indicating the division can be communicated between the base station and the mobile device. In some embodiments, a preemption indicator is transmitted that indicates a portion of a transport block that has been preempted by another data service, the preemption indicator being specified with a different granularity than a code block group. In some embodiments, for each code block group included in the transport block, acknowledgment information is transmitted indicating whether the code block group was successfully decoded by the user device. In various embodiments, the disclosed techniques can facilitate preemption with low latency reliable data services.
