MAC PDU Assembly with Pre-Grant Parameter Preparation in 5G

The patent applies preliminary action by enabling the WTRU to determine transmission parameters (MCS, resource allocation, TBS) and prepare data blocks before receiving the transmission grant. This early preparation includes segmenting data units, creating transport blocks, and configuring MAC PDUs in advance, so that when the grant is received, transmission can begin immediately with minimal processing delay.

The patent implements dynamics by introducing flexible grant sizes that can be adapted to the actual data block sizes requiring transmission. The network can dynamically adjust the grant size based on the WTRU's data buffer status and transmission requirements, allowing optimal resource allocation without wasting resources on fixed-size grants. This enables the system to efficiently handle varying data loads while maintaining simplified resource management through structured grant configurations.

The patent applies segmentation by dividing data units into manageable data blocks that can be independently processed and prepared before transmission. The WTRU segments incoming data into standardized blocks, applies appropriate segmentation identifiers, and organizes them into transport blocks that can be efficiently assembled into MAC PDUs. This segmentation approach simplifies the early preparation process by creating modular, standardized units that are easier to handle and transmit.

The patent applies partial action by implementing a tiered blind decoding approach where the WTRU performs decoding with varying levels of robustness based on the data's QoS requirements. For high-reliability data, more extensive blind decoding is performed to ensure accurate parameter determination. For lower-priority data, simplified decoding is used, reducing processing time. This selective approach balances reliability requirements with processing efficiency across different data types.
