PRB Bundling Size Configuration for Channel Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in communication systems is determining an optimal bundling size for physical resource blocks (PRBs) to improve channel estimation accuracy, as existing methods lack a standardized approach for configuring bundling sizes based on user equipment capabilities.
Innovation Solution
A method where user equipment reports its capability information to a network-side device, which configures a bundling size set, allowing for one-PRB or multi-PRB bundling, and uses a default or dynamically adjusted bundling size for data transmission, depending on the device's support for one-PRB bundling and the network's dynamic adjustment settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If PRB bundling technology is used to improve channel estimation accuracy, then channel estimation accuracy is improved, but the complexity of determining optimal bundling size increases
Solution Approach 1:
The patent implements dynamic bundling size adjustment where the network-side device can dynamically configure different bundling sizes based on channel conditions and user equipment capabilities. The bundling size is no longer fixed but can be adapted in real-time through RRC signaling, resolving the contradiction by making the system flexible rather than static.
Solution Approach 2:
The patent changes the parameter of bundling size from a fixed value to a configurable parameter that can be adjusted based on capability information and channel conditions. By introducing capability information reporting and dynamic configuration mechanisms, the system can optimize bundling size parameters without increasing determination complexity.
2Adaptability or versatility
If dynamic bundling size adjustment is enabled to adapt to different user equipment capabilities, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by having user equipment report capability information in advance before actual data transmission. The network-side device uses this pre-reported capability information to determine appropriate bundling sizes, avoiding the need for complex real-time negotiations and reducing overall system complexity.
Solution Approach 2:
The patent implements feedback mechanisms where user equipment reports capability information back to the network-side device. This feedback loop enables the network to understand equipment capabilities and configure appropriate bundling sizes, improving adaptability while keeping the configuration process systematic rather than ad-hoc.
3Power
If bundling size is increased to improve frequency-selective beamforming gain, then beamforming gain is improved, but channel estimation accuracy may deteriorate
Solution Approach 1:
The patent makes bundling size dynamic rather than fixed, allowing the system to adjust bundling sizes based on specific channel conditions and frequency selectivity requirements. This dynamic adjustment enables optimization of both beamforming gain and channel estimation accuracy by selecting appropriate bundling sizes for different scenarios.
Solution Approach 2:
The patent applies local quality by allowing different bundling sizes to be configured for different user equipment and different frequency resources. Instead of using a uniform bundling size across all scenarios, the system can apply locally optimized bundling sizes that match specific channel conditions, thereby simultaneously achieving good beamforming gain and channel estimation accuracy.

AI summary
A method for determining a bundling size, user equipment and a network-side device are provided The method includes: reporting, by user equipment, capability information to a network-side device, where the capability information is used to indicate whether the user equipment supports one-physical resource block bundling, and receiving a bundling size set configured by the network-side device for the user equipment according to the capability information, where supporting the one-physical resource block bundling indicates that a turn-off of a physical resource block bundling function is supported; and/or using, by the user equipment, a default bundling size or a bundling size configured via a higher-layer signaling to transmit data if the network-side device turns off a function of dynamic bundling size adjustment.
