Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of services like extended reality (XR) and ultra-reliable low-latency communications (URLLC) into communications systems results in a mismatch between the configuration of access network devices and the transmission requirements of target data, leading to inadequate resource allocation and power consumption issues.
Innovation Solution
A wireless communication method where a communications device, such as a terminal or core network device, transmits first information to an access network device, including details about target data features like transmission direction, arrival time, packet size, and dynamic changes, enabling the access network device to optimize resource allocation and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the access network device performs configuration at a terminal device granularity (scheduling resources, allocating resources, or configuring parameters), then the configuration can be tailored to individual terminals, but it results in a mismatch between the configuration and the transmission requirement of target data, failing to meet the transmission requirement
Solution Approach 1:
The patent segments the configuration granularity from terminal device level to data level. The access network device receives first information indicating data volume of target data at a data granularity, and performs resource allocation and configuration adjustments based on this fine-grained data information, enabling precise matching between configuration and transmission requirements.
Solution Approach 2:
The patent implements dynamic resource allocation by having the access network device adjust resource allocation and configuration parameters based on real-time data volume information of target data. The configuration is no longer static at terminal level but dynamically adapts to the actual transmission needs of each data packet.
2Ease of manufacture
If the access network device allocates resources at terminal device granularity, then resource allocation can be simplified, but it leads to inadequate resource allocation for specific data transmission requirements
Solution Approach 1:
The terminal device performs preliminary measurement of the data volume of target data before transmission, and reports this information to the access network device via first information. This preliminary action enables the access network device to make informed resource allocation decisions, improving transmission efficiency without complex real-time adjustments.
Solution Approach 2:
The patent establishes a feedback mechanism where the terminal device measures and reports data volume information to the access network device, which then uses this feedback to optimize resource allocation. This closed-loop feedback system ensures resource allocation matches actual transmission requirements.
3Measurement precision
If the access network device performs detailed configuration for each terminal device, then configuration precision can be improved, but it results in unnecessary power consumption
Solution Approach 1:
Instead of performing full terminal-level configuration for all terminals, the access network device applies detailed configuration only to terminal devices that have target data transmission requirements. By using first information to identify which terminals need configuration, the system avoids unnecessary power consumption from configuring terminals with no data to transmit.
4Use of energy by moving object
If the access network device uses coarse-grained configuration, then power consumption can be reduced, but it fails to meet the transmission requirements of XR and URLLC services
Solution Approach 1:
The terminal device performs preliminary measurement and reporting of data volume information before transmission. This preliminary action enables the access network device to identify exactly which terminals have transmission needs, allowing detailed configuration only when necessary, thus meeting service requirements while avoiding unnecessary power consumption.
