RETRANSMISSION METHOD AND APPARATUS IN MULTI-TRANSMISSION RECEPTION POINT ARCHITECTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17960656 titled 'RETRANSMISSION METHOD AND APPARATUS IN MULTI-TRANSMISSION RECEPTION POINT ARCHITECTURE
Simplified Explanation
The patent application describes a method and apparatus for improving Hybrid Automatic Repeat Request (HARQ) retransmission performance in a multi-transmission reception point architecture.
- The method involves receiving downlink control information from a network device on a control resource and receiving a retransmission version of downlink data based on the control information.
- The retransmission version is a retransmission of a previous version of the downlink data.
- The downlink control information for scheduling the retransmission version is associated with a different control resource.
- The control resources can be the same or belong to the same resource group.
Potential applications of this technology:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
Problems solved by this technology:
- Improves HARQ retransmission performance in a multi-transmission reception point architecture.
- Enhances the reliability and efficiency of data transmission in wireless communication systems.
Benefits of this technology:
- Improved data transmission reliability
- Enhanced performance of HARQ retransmissions
- Increased efficiency in multi-transmission reception point architectures.
Original Abstract Submitted
Embodiments of this application disclose a retransmission method and an apparatus in a multi-transmission reception point architecture, to improve HARQ retransmission performance in the multi-TRP architecture. The method includes: receiving first downlink control information from a network device on a first control resource; and receiving a first transmission version of downlink data from the network device based on the first downlink control information. The first transmission version is retransmission data of a second transmission version of the downlink data. Second downlink control information for scheduling the second transmission version is associated with a second control resource. The first control resource and the second control resource are a same control resource, or the first control resource and the second control resource belong to a same resource group.
