User Equipment PUSCH Redundancy Version Determination

The patent segments PUSCH repetitions into multiple blocks, where each block can be independently assigned redundancy versions. This segmentation allows the system to maintain coverage enhancement through repeated transmissions while improving resource allocation efficiency by enabling more flexible and granular control over redundancy version assignment across different blocks, rather than applying a single redundancy version to all repetitions.

The patent changes the parameter of redundancy version assignment by introducing block-based segmentation, where the redundancy version is determined based on the block index and a starting redundancy version parameter. This parameter change approach allows sub-PRB resource allocation to maintain high spectral efficiency while reducing the complexity of redundancy version determination, as the redundancy version can be calculated using a simple formula rather than complex lookup tables or extensive signaling.

The patent applies preliminary action by configuring the starting redundancy version parameter in advance through higher-layer signaling (RRC configuration). This preliminary configuration allows the UE to autonomously determine the redundancy version for each block based on the block index and the pre-configured starting value, eliminating the need for per-block redundancy version signaling and thus reducing signaling overhead while maintaining reliability through diverse redundancy version assignment.
