Pre-encoded Data Packet Variants for Low Latency Wireless Transmission

The patent applies preliminary action by pre-encoding and pre-modulating multiple data packet variants before the scheduling grant is received. The communication device prepares several encoded versions of the data packet with different coding and modulation parameters in advance, so that when the scheduling grant arrives, the device can immediately transmit the appropriate pre-prepared variant without performing real-time encoding and modulation, thus reducing latency while maintaining reliability

The patent uses parameter changes by creating multiple data packet variants with different coding and modulation parameters. Each variant is encoded with different combinations of coding rate, modulation order, or other physical layer parameters. When transmitted, the appropriate variant is selected based on the scheduling grant conditions, allowing the system to adapt to different channel conditions and resource allocations without real-time processing

The patent applies segmentation by dividing the encoding and modulation process into separate stages. The pre-encoding stage creates multiple variants with different coding parameters, and the pre-modulation stage creates variants with different modulation parameters. These segmented processing stages are performed in advance, allowing the device to store multiple prepared variants without requiring complex real-time processing capabilities during transmission

The patent reduces device complexity during transmission by performing the complex encoding and modulation operations in advance. The device prepares multiple data packet variants beforehand and stores them in a buffer, so that when transmission is triggered, the device only needs to retrieve and transmit the appropriate pre-prepared variant, significantly reducing the computational complexity required during the actual transmission process
