UE REFERENCE TIMING FOR CFRA ON SERVING CELL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17756931 titled 'UE REFERENCE TIMING FOR CFRA ON SERVING CELL

Simplified Explanation

The patent application describes systems and methods for determining the timing of a Random Access Channel (RACH) occasion triggered by the receipt of a Physical Downlink Control Channel (PDCCH) order. Here are some key points from the abstract:

• User equipment (UE) receives a PDCCH order and determines a timing offset value between the RACH occasion and a signal to be used as a timing source.
• The UE also determines the arrival time of the signal to be used at the timing source.
• The UE then determines the time of the RACH occasion according to the arrival time and the timing offset value, accounting for Timing Advance (TA) values if necessary.

Potential Applications

This technology could be applied in various wireless communication systems where efficient timing synchronization is crucial, such as 5G networks, Internet of Things (IoT) devices, and industrial automation systems.

Problems Solved

This technology solves the problem of accurately determining the timing of RACH occasions triggered by PDCCH orders, ensuring efficient and reliable communication in wireless networks.

Benefits

The benefits of this technology include improved synchronization accuracy, reduced interference, enhanced network efficiency, and better overall performance of wireless communication systems.

Potential Commercial Applications

Potential commercial applications of this technology include telecommunications equipment manufacturing, network infrastructure development, IoT device manufacturing, and any industry that relies on wireless communication systems.

Possible Prior Art

One possible prior art could be the use of timing advance techniques in wireless communication systems to improve timing synchronization between devices.

Unanswered Questions

How does this technology impact battery life in user equipment?

The patent application does not address how the implementation of these systems and methods may affect the battery life of user equipment. This could be an important consideration, especially for mobile devices that rely on efficient power management.

Are there any limitations to the accuracy of timing synchronization using this technology?

The patent application does not mention any potential limitations or challenges that may arise in achieving precise timing synchronization in all operating conditions. It would be important to understand the constraints of this technology in real-world scenarios.

Original Abstract Submitted

Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of an physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.
