SYSTEMS, METHODS, AND APPARATUSES FOR QUASI-CO-LOCATION (QCL) AND SPATIAL RELATION ASSUMPTIONS DURING RANDOM ACCESS PROCEDURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17766537 titled 'SYSTEMS, METHODS, AND APPARATUSES FOR QUASI-CO-LOCATION (QCL) AND SPATIAL RELATION ASSUMPTIONS DURING RANDOM ACCESS PROCEDURES
Simplified Explanation
The patent application describes techniques using quasi-co-location (QCL) capabilities and spatial relation assumption for a UE to designate a single beam for connections with a base station during a PRACH procedure. The beam can be reset after a pre-determined duration or maintained until additional TCI is received. It also covers scenarios with multiple TRPs and switching between beam management schemes based on factors like device capabilities.
- Quasi-co-location (QCL) capabilities and spatial relation assumption used for beam designation during PRACH procedure
- Beam can be reset or maintained based on decoding latency or TCI reception
- Scenarios with multiple transmission reception points (TRPs) and switching between beam management schemes based on device capabilities
Potential Applications
- 5G and future wireless communication systems
- IoT devices with limited power and processing capabilities
Problems Solved
- Efficient beam management during PRACH procedure
- Handling multiple TRPs and device capabilities effectively
Benefits
- Improved connection reliability and efficiency
- Enhanced performance in crowded or interference-prone environments
Original Abstract Submitted
Techniques described herein involve the use of quasi-co-location (QCL) capabilities and spatial relation assumption to enable a UE to designate a single beam for connections with a base station during a physical random access channel (PRACH) procedure. Once the PRACH procedure is complete, the beam may be reset after a pre-determined duration, which may account for decoding latency, or maintained until additional transmission configuration indication (TCI) is received. Also addressed are scenarios involving multiple transmission reception points (TRPs) and switching between beam management schemes based on one or more factors including device capabilities.
