SUPPLEMENTARY UPLINK IN WIRELESS SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240323774 titled 'SUPPLEMENTARY UPLINK IN WIRELESS SYSTEMS
The abstract discusses the use of supplementary uplink (SUL) in wireless systems, providing cell suitability criteria for cells configured with SUL. A wireless transmit/receive unit (WTRU) may receive paging with an indication of a carrier (e.g., SUL or regular uplink (RUL)) for initial access. The WTRU may provide beam information for beamforming of a paging message on a non-beamformed SUL and may undergo a handover procedure for a configured SUL. The WTRU can request a change of configured uplink and autonomously switch to a different uplink based on certain conditions. Semi-persistent scheduling resources/configuration may be relocated from one uplink to another.
- SUL is used in wireless systems with specific cell suitability criteria.
- WTRU receives paging with carrier indication for initial access.
- WTRU provides beam information for beamforming on non-beamformed SUL.
- Handover procedure is available for WTRU with configured SUL.
- WTRU can autonomously switch to a different uplink based on conditions.
- Semi-persistent scheduling resources/configuration can be moved between uplinks.
Potential Applications: - Enhanced wireless communication systems - Improved network efficiency and performance
Problems Solved: - Efficient utilization of supplementary uplink in wireless systems - Seamless handover procedures for WTRUs with configured SUL
Benefits: - Enhanced network reliability and coverage - Optimal resource allocation for improved performance
Commercial Applications: Title: Enhanced Wireless Communication Systems with Supplementary Uplink This technology can be utilized in telecommunications, IoT devices, and smart city infrastructure for improved connectivity and data transmission.
Questions about the technology: 1. How does the use of supplementary uplink benefit wireless systems? 2. What are the key advantages of autonomous switching between uplinks for WTRUs?
Original Abstract Submitted
supplementary uplink (sul) may be used in wireless systems. cell suitability criteria may be provided for cells configured with sul. a wireless transmit/receive unit (wtru) may receive paging with an indication of a carrier (e.g., sul or regular uplink (rul) in which to initiate part or all of an initial access. a wtru that may be performing response-driven paging may provide (e.g. explicit) beam information for beamforming of a paging message on a non-beamformed sul. a handover (ho) procedure (e.g., carrier selection, configuration handling, ho failure, etc.) may be provided for a wtru with a configured sul. a wtru may request a change of a configured ul. a wtru may (e.g., autonomously) perform a switch to a different (e.g., configured) uplink, for example, when one or more conditions may be met (e.g., conditional switch). semi-persistent scheduling (sps) resources/configuration may be relocated from a first ul to a second ul.
