REDUNDANCY GAP INDICATION FOR IMPROVED DATA TRANSMISSION

Title:

REDUNDANCY GAP INDICATION FOR IMPROVED DATA TRANSMISSION

Document Type and Number:

WIPO Patent Application WO/2021/203308

Kind Code:

A1

Abstract:

Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.
