Terminal Equipment HARQ Feedback for Multi-PDSCH Scheduling

The patent applies local quality by differentiating HARQ feedback requirements for different PDSCHs within the same scheduling occasion. Specifically, when a DCI schedules multiple PDSCHs, the patent enables selective HARQ feedback transmission based on individual PDSCH characteristics (such as whether each PDSCH is the last in its HARQ process), rather than requiring uniform feedback for all PDSCHs. This reduces uplink control signaling overhead while maintaining reliability for critical data transmissions.

The patent implements periodic action by enabling terminal equipment to monitor PDCCH only at specific periodic intervals rather than continuously. The network configures discontinuous reception (DRX) parameters that define active monitoring periods and sleep periods. During active periods, the terminal monitors for DCI messages containing scheduling information and HARQ feedback requirements. During sleep periods, the terminal powers down monitoring functions, significantly reducing power consumption and complexity while maintaining scheduling responsiveness when data needs to be transmitted.

The patent applies merging by combining multiple PDSCH scheduling operations into a single DCI message. When the network needs to schedule multiple PDSCHs, it generates one DCI that contains scheduling information for all PDSCHs, including resource allocations, modulation and coding schemes, and HARQ process identifiers for each PDSCH. The terminal receives this single DCI, parses the multiple PDSCH schedules, and processes them accordingly. This approach improves productivity by reducing control signaling overhead and processing steps, while the patent manages the increased device complexity through standardized parsing procedures and efficient memory management for storing multiple PDSCH configurations.
