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

This abstract first appeared for US patent application 20240179758 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 occasion (RO) used to transmit a contention-free random access (CFRA) preamble triggered by the receipt of a physical downlink control channel (PDCCH) order in a PDCCH.

• 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.

Potential Applications

This technology can be applied in:

• Wireless communication systems
• Internet of Things (IoT) devices
• Mobile networks

Problems Solved

• Efficient timing determination for transmitting CFRA preambles
• Improved synchronization in wireless communication systems

Benefits

• Enhanced reliability of communication
• Reduced interference
• Improved network efficiency

Potential Commercial Applications

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.
