Base Station Signal Synthesis for Faster Uplink Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems experience delays in uplink communication due to the time required for a terminal to transmit a scheduling request and receive radio resource allocation from a base station, which increases overall communication latency.
Innovation Solution
The base station includes a signal processor that generates and adds a scheduling request to the uplink signal on behalf of the terminal, reducing the need for the terminal to transmit the request, thereby shortening the delay by processing the signal within the base station's protocol stack.

Engineering Contradiction Analysis
1Loss of time
If the terminal transmits a scheduling request to the base station to request radio resource allocation, then the terminal can obtain radio resources for data transmission, but the uplink communication delay increases due to the time required for request transmission and allocation processing
Solution Approach 1:
The patent inverts the traditional scheduling request mechanism by having the base station generate and transmit scheduling requests on behalf of the terminal, rather than the terminal transmitting requests to the base station. This inversion eliminates the terminal's scheduling request transmission step and reduces uplink communication delay.
Solution Approach 2:
The base station performs self-service by autonomously generating scheduling requests for terminals based on pre-configured allocation information, eliminating the need for terminals to actively request resources. The base station monitors terminal data buffer status and initiates scheduling requests automatically.
2Productivity
If the base station processes scheduling requests and generates synthesis signals within its protocol stack, then uplink communication efficiency improves, but the base station's processing complexity increases
Solution Approach 1:
The patent merges the scheduling request generation function with the base station's existing signal processing functions. The base station combines allocation information from higher layers with physical layer signals to generate synthesis signals, consolidating multiple functions into a unified processing architecture.
Solution Approach 2:
The base station's signal processor is designed to perform multiple functions: monitoring terminal data status, generating scheduling requests, creating allocation information, and synthesizing physical layer signals. This multi-functional approach improves efficiency while managing complexity through integration.

AI summary
According to one embodiment, an electronic apparatus is arranged at an interface between a first layer and a second layer in a base station, and includes a processor and a memory configured to store allocation information indicating a radio resource for a first control signal. The first layer is configured to transmit a physical layer signal to the second layer. The processor is configured to generate a second control signal based on the allocation information, generate a synthesis signal by adding the second control signal to the physical layer signal, and transmit the synthesis signal to the second layer.
