Base Station Processor Layer Division for Uplink Scheduling Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication delays occur in uplink communication from terminals to base stations due to the time taken for scheduling requests and allocations, leading to inefficiencies in 4G and 5G wireless communication systems.
Innovation Solution
An electronic apparatus with a processor that divides the base station's layers into functional units, using the nFAPI interface protocol to manage message processing and timing, allowing for the generation and transmission of scheduling requests independently of terminals, thereby reducing communication delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal takes the procedure of detecting transmission message, transmitting scheduling request, receiving scheduling allocation, then the uplink communication can be established, but communication delay occurs
Solution Approach 1:
The base station performs scheduling allocation in advance before the terminal actually needs to transmit data. The processor generates scheduling allocation messages proactively and transmits them to terminals ahead of time, so that when terminals need to send data, the resource allocation is already ready, eliminating the delay caused by the traditional sequence of scheduling request → allocation → data transmission
Solution Approach 2:
The patent inverts the traditional scheduling initiation direction. Instead of the terminal initiating the scheduling process by sending a scheduling request, the base station autonomously generates and transmits scheduling allocation messages to terminals. This reversal eliminates the need for terminal-initiated scheduling requests and their associated delays
2Reliability
If the base station processes messages through multiple layers, then proper protocol handling is achieved, but processing time increases
Solution Approach 1:
The base station's message processing function is segmented into distinct modular components: a message reception unit that receives messages from higher layers, a message generation unit that creates scheduling allocation messages, and a message transmission unit that sends messages to lower layers. This segmentation allows each component to operate independently and efficiently, reducing overall processing time while maintaining protocol accuracy
Solution Approach 2:
The processor acts as an intermediary component between the message reception unit and the message transmission unit. It receives scheduling allocation information from the reception unit, processes and generates the appropriate allocation messages, and forwards them to the transmission unit. This intermediary role streamlines the message flow through the protocol layers, reducing processing delays

AI summary
According to one embodiment, an electronic apparatus includes a processor located in an interface which divides layers of a base station. The processor is configured to receive a first message transmitted from a first layer which is one of a next lower layer and a next upper layer, interpret the first message and transmit an interpreted message to a second layer which is the other layer, generate a second message based on 3 v the interpreted message, transmit the second message to the second layer, and control timing of transmitting the second message.
