CHANNEL STATE INFORMATION (CSI) REPORTING TECHNIQUES FOR SECONDARY CELL (SCELL) ACTIVATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18049493 titled 'CHANNEL STATE INFORMATION (CSI) REPORTING TECHNIQUES FOR SECONDARY CELL (SCELL) ACTIVATION

Simplified Explanation

The patent application describes a system for supporting channel state information (CSI) reporting techniques for secondary cell (SCell) activation in a user equipment (UE) within a network.

• The UE receives MAC-CEs indicating SCell activation command, AP-TRS trigger, and AP-CSI report trigger.
• The network entity signals these triggers in MAC-CEs.
• The UE measures AP-TRS and performs measurements via AP-CMR and AP-IMR according to the triggers.
• The UE transmits an AP-CSI report associated with the measurements.

Potential Applications

This technology could be applied in wireless communication systems to enhance the efficiency of SCell activation and CSI reporting processes.

Problems Solved

This innovation solves the problem of efficiently managing SCell activation and CSI reporting in wireless networks, improving overall network performance.

Benefits

The benefits of this technology include improved network efficiency, enhanced communication reliability, and optimized resource allocation for better user experience.

Potential Commercial Applications

One potential commercial application of this technology could be in 5G networks to improve network performance and enhance user experience.

Possible Prior Art

One possible prior art could be related to existing techniques for CSI reporting and SCell activation in wireless communication systems.

How does this technology impact battery life in UEs?

This technology could potentially impact battery life in UEs due to increased measurement and reporting activities. Further research is needed to understand the exact impact and potential optimizations.

What are the security implications of transmitting AP-CSI reports?

Transmitting AP-CSI reports may raise security concerns regarding the privacy of network information. It is essential to address security measures to protect sensitive data during transmission.

Original Abstract Submitted

This disclosure provides systems, methods and apparatuses that support channel state information (CSI) reporting techniques for secondary cell (SCell) activation. A user equipment (UE) may receive one or more medium access control-control elements (MAC-CEs) that indicate a secondary cell (SCell) activation command, an aperiodic tracking reference signal (AP-TRS) trigger, and an aperiodic channel state information (AP-CSI) report trigger. The network entity may signal the SCell activation command, the AP-TRS trigger, and the AP-CSI report trigger in the same MAC-CE or in separate MAC-CEs. The UE may receive and measure AP-TRS in accordance with the AP-TRS trigger indicated by the one or more MAC-CEs, and may perform measurements via an aperiodic channel measurement resource (AP-CMR) and an aperiodic interference measurement resource (AP-IMR) in accordance with the AP-CSI report trigger indicated by the one or more MAC-CEs. Accordingly, the UE may transmit an AP-CSI report associated with the measurements.
