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

This abstract first appeared for US patent application 17913757 titled 'METHOD FOR SIMULTANEOUS RECEPTION OF SSB AND OTHER SIGNALS

Simplified Explanation

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

Key Features and Innovation

UE determines the synchronization signal block (SSB) to receive when multiple SSBs from different cells are present in a slot.
UE identifies other signals in the same symbols with the selected SSB based on signal type and SSB functionality.
UE selects the corresponding quasi co-location (QCL) assumption to receive downlink signals from another cell.
UE can report support for one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

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.
