5G Base Station Buffer Skipping for Overlap Resource Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the allocation of resources for ultra-reliable and low latency communications (URLLC) services leads to reduced efficiency in data transmission/reception due to collisions with resources for other services, necessitating an efficient use of radio resources.
Innovation Solution
A method for a base station (BS) to identify and manage overlap regions between dynamically allocated and predetermined resource regions, allowing the BS to skip storage of signals in a buffer if they are received in overlap regions, thereby optimizing resource usage and reducing transmission delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If URLLC resources are increased to meet ultra-reliability and low latency requirements, then service reliability is improved, but resource collision with other services increases and transmission efficiency deteriorates
Solution Approach 1:
The resource pool is segmented into multiple resource regions including first resource regions for URLLC services and second resource regions for other services. This segmentation allows different service types to be allocated distinct resource areas, reducing collisions while maintaining URLLC reliability requirements
Solution Approach 2:
Different resource regions are assigned different quality characteristics suitable for specific service requirements. URLLC resources are allocated with high reliability guarantees in specific regions, while other services use different regions, creating local optimization for each service type
2Reliability
If signals received in overlap regions are stored in buffer for potential retransmission, then transmission reliability is improved, but buffer memory usage increases and processing complexity worsens
Solution Approach 1:
The base station performs preliminary identification of overlap regions before storing signals. By pre-determining which resource regions are overlap regions based on configuration information, the system avoids unnecessary buffer storage operations for signals that cannot be successfully decoded, reducing buffer management complexity
Solution Approach 2:
Instead of storing all received signals and then determining what to keep, the system inverts the approach by identifying overlap regions first and skipping storage for signals in those regions. This inversion reduces unnecessary buffer operations while maintaining reliability for non-overlap region signals
3Productivity
If overlap region identification and buffer skipping operations are implemented, then resource usage efficiency is improved, but base station processing complexity increases
Solution Approach 1:
Configuration information defining overlap regions is pre-established and provided to the base station before data transmission. This preliminary setup allows the base station to quickly identify overlap regions during operation without complex real-time calculations, improving resource efficiency while limiting processing complexity increases
Solution Approach 2:
The base station uses the provided configuration information to autonomously identify overlap regions and make buffer storage decisions without requiring complex external control or coordination. This self-service approach improves resource efficiency while keeping the processing logic relatively simple

AI summary
The present disclosure relates to a 5th generation 5G) or pre-5G communication system for supporting higher data rates beyond a 4th generation (4G) communication system such as long-term evolution (LTE). A method for a base station (BS) are provided. The method includes receiving signals from at least one terminal, decoding a signal having a signal strength that is higher than a threshold value among the received signals, identifying whether a resource through which the signal has been transmitted is included in an overlap region in which a first resource region dynamically allocated by control information and a second resource region predetermined by configuration information overlap each other if the decoding of the signal fails, and skipping storage of the received signal in a buffer if the resource through which the signal has been transmitted is included in the overlap region.
