Base Station Uplink Parameter Reservation for Wireless Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems face inefficiencies in uplink data transmission due to high control signal overhead, particularly when uplink data is frequently transmitted, which can lead to reduced communication efficiency and increased power consumption.
Innovation Solution
A wireless communications system where a base station reserves radio parameters for uplink data transmission in advance and provides authorization through control signals, allowing the wireless station to transmit data using preconfigured parameters, thereby reducing the need for frequent notifications and control signal overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If control signals are transmitted for each uplink data transmission to notify radio parameters, then transmission accuracy is improved, but control signal overhead increases and communication efficiency deteriorates
Solution Approach 1:
The base station performs preliminary configuration of radio parameters (frequency resources, modulation scheme, coding scheme) through RRC signaling before actual uplink data transmission. This preliminary action allows the wireless station to use these pre-configured parameters for multiple transmissions without requiring repeated control signals, thereby reducing overhead while maintaining transmission accuracy.
2Reliability
If control signals are transmitted for each uplink data transmission, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
Radio parameters are configured in advance through RRC connection setup or reconfiguration messages, eliminating the need for repeated control signal transmissions. This reduces the power consumption of the wireless station while maintaining reliable transmission through the use of pre-optimized parameters.
3Adaptability or versatility
If radio parameters are configured for each transmission, then adaptability to changing conditions is improved, but control signal overhead increases
Solution Approach 1:
The base station configures radio parameters in advance based on initial channel conditions and quality of service requirements. These pre-configured parameters remain valid until RRC reconfiguration is needed, reducing control signal overhead while maintaining sufficient adaptability to changing wireless conditions.

AI summary
A wireless communications system includes a base station; and a wireless station. The base station reserves, in advance, a radio parameter that includes at least any one among a frequency resource and communication method used in transmission of uplink data by a first control signal transmitted to the wireless station and upon receiving a second control signal from the wireless station, provides authorization for the transmission of uplink data, by transmitting a third control signal to the wireless station. The wireless station, upon transmitting the second control signal to the base station, uses the radio parameter configured by the first control signal received from the base station to perform transmission of the uplink data to the base station.
