METHODS AND APPARATUSES FOR TCI STATE INDICATION IN A WIRELESS COMMUNICATIONS SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17811061 titled 'METHODS AND APPARATUSES FOR TCI STATE INDICATION IN A WIRELESS COMMUNICATIONS SYSTEM
Simplified Explanation
The patent application describes methods and apparatuses for indicating the state of transmission configuration in a wireless communication system. It specifically focuses on the transmission configuration indication (TCI) state indication.
- The method involves a user equipment (UE) receiving downlink control information (DCI) that includes TCI codepoints indicating different TCI states.
- Based on the TCI states, the UE determines a quasi co-location (QCL) assumption for receiving a physical downlink control channel (PDCCH).
- The UE then receives the PDCCH, which schedules the transmission occasions of physical downlink shared channels (PDSCHs).
- The method also includes receiving information on PDSCH repetition schemes and determining QCL assumptions for receiving each PDSCH based on the TCI states.
Potential applications of this technology:
- Wireless communication systems
- Mobile networks
- Internet of Things (IoT) devices
- 5G and future generations of wireless networks
Problems solved by this technology:
- Efficient transmission configuration indication in wireless communication systems
- Optimizing the reception of PDCCH and PDSCH based on TCI states
- Enhancing the overall performance and reliability of wireless networks
Benefits of this technology:
- Improved transmission efficiency
- Enhanced network performance and reliability
- Better utilization of available resources
- Increased capacity and throughput in wireless communication systems
Original Abstract Submitted
Methods and apparatuses for transmission configuration indication (TCI) state indication in a wireless communication system. A method for operating a user equipment (UE) includes receiving a downlink control information (DCI) including at least one TCI codepoint indicating first and second TCI states; determining, based on the first or second TCI states, a third quasi co-location (QCL) assumption for receiving a physical downlink control channel (PDCCH); and receiving the PDCCH that schedules first or second transmission occasions of a first or second physical downlink shared channels (PDSCHs), respectively. The method further includes receiving information on PDSCH repetition schemes; determining, based on the first or second TCI states, a first QCL assumption for receiving the first PDSCH; and determining, based on the first or second TCI states, a second QCL assumption for receiving the second PDSCH.
