SOUNDING REFERENCE SIGNAL (SRS) ENHANCEMENT FOR MULTI-TRANSMISSION AND RECEPTION POINT (TRP) OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18199460 titled 'SOUNDING REFERENCE SIGNAL (SRS) ENHANCEMENT FOR MULTI-TRANSMISSION AND RECEPTION POINT (TRP) OPERATION

Simplified Explanation

The abstract of this patent application describes apparatuses and methods for reducing interferences for Sounding Reference Signal (SRS) in wireless communication systems. This can be achieved through frequency domain interference randomization, code domain interference randomization, or power control techniques.

• User equipment (UE) is configured to determine a comb offset and/or a cyclic shift for each SRS transmission occasion. These values change between different SRS transmission occasions.
• The UE then transmits an SRS to the base station using the determined comb offset and/or cyclic shift during the corresponding SRS transmission occasion.

Potential applications of this technology:

• Wireless communication systems: This technology can be applied in various wireless communication systems to reduce interferences and improve the overall performance of SRS transmissions.

Problems solved by this technology:

• Interference reduction: The technology addresses the problem of interferences that can degrade the quality and reliability of SRS transmissions. By implementing mechanisms like frequency domain interference randomization and power control, interferences can be minimized.

Benefits of this technology:

• Improved signal quality: By reducing interferences, the technology can enhance the quality of SRS transmissions, leading to better communication performance.
• Increased reliability: Minimizing interferences can also improve the reliability of SRS transmissions, ensuring that the signals are accurately received and interpreted by the base station.

Original Abstract Submitted

Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.
