Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in implementing simultaneous transmission via multi-panel (STxMP) is how to adapt resource indication schemes for different antenna panels to meet varying terminal configurations and requirements in uplink transmission.
Innovation Solution
A method and apparatus for configuring Physical Uplink Shared Channel (PUSCH) transmission resource parameters, including maximum transmission data layers, codebook parameters, and Sounding Reference Signal (SRS) resource sets, to support symmetric and asymmetric panel transmissions, enabling dynamic switching between Multiple-Transmission Reception Point (M-TRP) and Single-Transmission Reception Point (S-TRP) modes.

Engineering Contradiction Analysis
1Adaptability or versatility
If a unified resource indication scheme is used for all antenna panels, then the system complexity is reduced, but it cannot adapt to different terminal configurations and requirements
Solution Approach 1:
The patent segments the resource indication scheme by introducing panel-specific configuration parameters. Each antenna panel can be independently configured with its own maximum number of transmission data layers, codebook parameters, and SRS resource set configurations. This segmentation allows different terminal configurations to be accommodated without requiring a completely different unified scheme, thus improving adaptability while maintaining manageable complexity through structured parameter organization.
Solution Approach 2:
The patent implements dynamic adaptability by allowing the network device to flexibly configure PUSCH transmission resource parameters based on terminal capabilities and channel conditions. The configuration can be dynamically adjusted per panel and per transmission occasion, enabling the system to adapt to varying terminal configurations and requirements without being locked into a static unified scheme.
2Adaptability or versatility
If separate resource indication schemes are configured for each antenna panel, then adaptability to different terminal configurations is improved, but the configuration complexity increases
Solution Approach 1:
The patent applies universality by designing a standardized parameter structure that can serve multiple panels and different transmission scenarios. The same set of configuration parameters (maximum number of transmission data layers, codebook parameters, SRS resource set configurations) can be universally applied to any number of antenna panels, reducing the need for entirely separate configuration schemes for each panel while still providing panel-specific adaptability.
Solution Approach 2:
The patent manages configuration complexity by organizing panel-specific configurations through standardized parameter changes rather than structural modifications. Each panel's configuration is achieved by adjusting specific parameters (such as max number of layers, codebook subset) within a unified framework, rather than creating entirely separate indication schemes. This parameter-based approach reduces complexity while maintaining adaptability.
3Productivity
If the maximum number of transmission data layers is increased for M-TRP mode, then the transmission throughput is improved, but the requirement for terminal processing capability increases
Solution Approach 1:
The patent applies local quality by allowing different maximum numbers of transmission data layers to be configured for different panels and different transmission modes (M-TRP vs. S-TRP). Instead of requiring the terminal to support a uniformly high processing capability across all scenarios, the system can locally optimize the number of layers based on the specific transmission mode and panel configuration, thereby improving throughput where needed while reducing processing requirements in other scenarios.

AI summary
The present disclosure relates to a physical uplink shared channel (PUSCH) communication method and apparatus, and a storage medium. The method comprises : in response to determining that a terminal supports an uplink simultaneous transmission via multi-panel (STxMP) transmission, configuring a PUSCH transmission resource configuration parameter, wherein the PUSCH transmission resource configuration parameter corresponds to the terminal supporting symmetric panel transmission and/or asymmetric panel transmission; the PUSCH transmission resource configuration parameter comprises at least one of the following : a maximum number of transmission data layers, a codebook parameter, and a sounding reference signal (SRS) resource set configuration parameter; the SRS resource set configuration parameter is applied to codebook-based transmission and/or non-codebook-based transmission. According to the present disclosure, a higher uplink throughput rate and more reliable transmission performance are supported by means of uplink simultaneous transmission enhancement of multi-panel/multiple-transmission reception points.
