METHOD FOR SIMULTANEOUS RECEPTION OF SSB AND OTHER SIGNALS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240223336 titled 'METHOD FOR SIMULTANEOUS RECEPTION OF SSB AND OTHER SIGNALS

The abstract describes approaches for receiving downlink signals simultaneously using analog beamforming to enhance the link budget between the base station and user equipment (UE).

• The UE can determine the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot.
• The UE can determine if there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality.
• When there are other downlink signals like Channel State Information-Reference Signal (CSI-RS) or Physical Downlink Shared Channel (PDSCH) from another cell, the UE selects the corresponding Quasi Co-Location (QCL) assumption to receive the signals.
• The UE can report whether it can support one or two QCL types at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

Potential Applications: - 5G communication systems - Wireless networks - Mobile telecommunications

Problems Solved: - Enhancing downlink signal reception - Improving link budget between base station and UE - Efficient utilization of analog beamforming technology

Benefits: - Increased signal quality - Enhanced network performance - Improved user experience

Commercial Applications: Title: "Advanced Analog Beamforming Technology for Enhanced Downlink Signal Reception" This technology can be utilized in 5G base stations, mobile devices, and network infrastructure to improve signal reception and network efficiency, leading to better overall communication performance.

Questions about Analog Beamforming Technology: 1. How does analog beamforming technology differ from digital beamforming in wireless communication systems? Analog beamforming technology uses phase shifters and amplifiers to adjust the signal's phase and amplitude, while digital beamforming uses digital signal processing algorithms to manipulate the signal.

2. What are the key advantages of analog beamforming over digital beamforming in terms of signal reception and network performance? Analog beamforming offers lower complexity, reduced power consumption, and improved efficiency compared to digital beamforming, making it ideal for enhancing downlink signal reception in wireless communication systems.

Original Abstract Submitted

approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (ue). alternatives within these approaches include the ue determining the synchronization signal block (ssb) to receive when there are multiple ssbs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected ssb based on the type of signal and the ssb's functionality. in the case where there are another downlink signals channel state information-reference signal (csi-rs) or physical downlink shared channel (pdsch) from another cell, the ue selects the corresponding quasi co-location (qcl) assumption to receive the signals. optionally, the ue can report whether it can support one or two qcl-typed at a time and whether it supports ssbs in different cells multiplexed in overlapped symbols.
