Sounding Reference Signal Resource Capacity Enhancement for Wireless Communications - A simplified explanation of the abstract

This abstract first appeared for US patent application 17916898 titled 'Sounding Reference Signal Resource Capacity Enhancement for Wireless Communications

Simplified Explanation

The abstract describes features for increasing the resource capacity of sounding reference signals (SRS) in wireless communications. These features include:

• Introducing a larger comb size with comb hopping: This involves using a larger set of frequency positions for the SRS, which can increase the capacity of the SRS resource.
• Determining slot offset and/or comb offset for aperiodic SRS based on downlink control information (DCI) alone or based on both DCI and radio resource control (RRC): This allows for more efficient allocation of resources for aperiodic SRS, improving the overall capacity.
• Applying RB level frequency hopping within an SRS resource across different symbols: This involves hopping the frequency positions within an SRS resource, which can increase the capacity by utilizing different frequency positions.
• Applying time domain orthogonal cover code (TD-OCC) to symbols within an SRS resource: This technique applies a cover code to the symbols within an SRS resource, which can increase the capacity by improving the orthogonality of the signals.

Potential applications of this technology include:

• Increasing the capacity of wireless communication systems by optimizing the allocation of resources for sounding reference signals.
• Improving the efficiency of aperiodic sounding reference signals by determining the slot offset and/or comb offset based on control information.
• Enhancing the capacity of wireless communication systems by applying frequency hopping and time domain orthogonal cover codes to sounding reference signals.

The problems solved by this technology include:

• Limited resource capacity for sounding reference signals in wireless communication systems.
• Inefficient allocation of resources for aperiodic sounding reference signals.
• Lack of techniques to increase the capacity of sounding reference signals in wireless communication systems.

The benefits of this technology include:

• Increased resource capacity for sounding reference signals, leading to improved overall capacity of wireless communication systems.
• More efficient allocation of resources for aperiodic sounding reference signals, resulting in better utilization of available resources.
• Enhanced capacity through the use of frequency hopping and time domain orthogonal cover codes for sounding reference signals.

Original Abstract Submitted

Features for increasing sounding reference signal (SRS) resource capacity for wireless communications may include introducing a larger comb size with comb hopping, providing support to determine the slot offset and/or comb offset for aperiodic SRS based on downlink control information (DCI) alone or based on both DCI and radio resource control (RRC), applying RB level frequency hopping within an SRS resource across different symbols, and/or applying time domain orthogonal cover code (TD-OCC) to symbols within an SRS resource. The TD-OCC may be applied to SRS for codebook, non-codebook and antenna switching, and may also be applied simultaneously with comb hopping and/or RB level hopping in certain scenarios.
