SSB-LESS OPERATION FOR INTER-BAND CARRIER AGGREGATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18483314 titled 'SSB-LESS OPERATION FOR INTER-BAND CARRIER AGGREGATION

Simplified Explanation

The abstract describes a patent application related to a user equipment (UE) transmitting an indication of its capability to synchronize with a secondary cell based on measurements of a primary cell. The UE estimates propagation delay and angle of arrival of the secondary cell using synchronization signals from the primary cell, and performs various synchronization processes based on signals from the secondary cell.

• User equipment (UE) can transmit an indication of its synchronization capability to a secondary cell based on measurements of a primary cell.
• UE estimates propagation delay and angle of arrival of the secondary cell using signals from the primary cell.
• UE performs automatic gain control, timing synchronization, and frequency synchronization of the secondary cell based on signals from the secondary cell.
• UE conducts a receive beam sweep on a burst of a signal from the secondary cell, adjusting the range of the sweep based on the estimated angle of arrival.

Original Abstract Submitted

A user equipment (UE) may transmit, to a primary cell, an indication of a capability to synchronize with a secondary cell based on measurements of the primary cell. A UE may estimate a propagation delay (t) and an angle of arrival (AoA) of the secondary cell based on a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) transmitted by the primary cell. A UE may perform automatic gain control (AGC), fine timing synchronization, and fine frequency synchronization of the secondary cell based on a temporary aperiodic tracking reference signal (A-TRS) transmitted by the secondary cell. A UE may perform a receive beam sweep on a burst of a CSI-RS transmitted by the secondary cell, wherein a range of the receive beam sweep is based on the estimated AoA.
