Feedback-Based Retransmission Using Mixed Duration Transmission Time Intervals

摘要

A first transport block (TB) comprising a plurality of code blocks (CBs) transmitted to a receiver during a first transmission time interval (TTI) having a first duration, and selected from multiple available TTI durations Techniques for providing retransmission of any unsuccessfully received CBs in a second TTI with a duration are described. The second TTI may have a second TTI duration that is shorter than the first TTI duration, and may only have CB from the first TB. One or more of the time duration or frequency resources of the second TTI may be selected based on the number of CBs retransmitted in the second TTI.
