User Equipment PRG Size Configuration via PRB Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring the PRG size in wireless communications systems leads to significant signaling overheads, affecting transmission efficiency.
Innovation Solution
Configure the PRG size by setting it equal to the PRB bundling size, using a preset indication rule to select from a plurality of configured PRB bundling sizes, thereby reducing the need for dedicated signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated configuration signaling is used to configure the PRG size, then the PRG size can be flexibly changed based on specific requirements, but signaling overheads increase and transmission efficiency decreases
Solution Approach 1:
The PRB bundling size configuration is made to serve dual purposes: it functions both as the PRB bundling size for data transmission and as the PRG size for channel measurement. This multi-functionality eliminates the need for separate dedicated signaling for PRG size configuration, thereby reducing signaling overhead while maintaining the ability to flexibly adjust the size based on channel conditions and transmission requirements
Solution Approach 2:
The patent merges the PRG size configuration with the PRB bundling size configuration into a single parameter. By combining these two previously separate configuration parameters into one, the system reduces the amount of signaling required while ensuring that the same size parameter can be used for both data transmission bundling and channel measurement grouping, thus resolving the contradiction between flexibility and signaling overhead

AI summary
Embodiments of the present invention provide user equipment, including: a transceiver module, configured to receive configuration information, where the configuration information is used to configure at least one PRB bundling size; and a processing module, configured to determine a PRG size based on the at least one PRB bundling size. The embodiments of the present invention further provide an access device. In technical solutions provided in the embodiments of the present invention, the PRG size is configured by configuring the PRB bundling size. In this way, there is no need to set dedicated signaling for configuring the PRG size. This helps reduce signaling overheads caused by configuring the PRG size.
