Base Station Resource Position Determination for Wireless Feedback Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the time varying characteristics and multipath fading of wireless channels can lead to data transmission failures, particularly due to transmission time differences between different frequency bands, causing delayed feedback transmission.
Innovation Solution
A method for determining resource positions in a base station, where a specified transmission time difference is acquired between a second band and a first band, and resource positions are determined based on this time difference and existing resource positions in both bands to ensure timely feedback data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal transmits feedback data through the uplink resource position of the second band, then the base station can receive feedback data, but the transmission time difference causes the feedback data to be transmitted delayed
Solution Approach 1:
The base station calculates and determines the second resource position in advance based on the first resource position and transmission time difference parameters, so that when the terminal needs to transmit feedback data, the resource position is already prepared and aligned, eliminating transmission delay
Solution Approach 2:
The patent adjusts the resource position parameters by introducing a transmission time difference parameter between the first and second bands, and uses this parameter to recalculate and determine the second resource position, thereby synchronizing the feedback transmission timing
2Ease of operation
If the terminal waits for the next uplink resource position to transmit feedback data, then the feedback data can be transmitted, but the transmission is delayed
Solution Approach 1:
The base station performs preliminary calculation of the second resource position based on the first resource position and transmission time difference, enabling the terminal to transmit feedback data immediately without waiting for the next available uplink resource position
Solution Approach 2:
The patent introduces a resource position determination mechanism that acts as an intermediary between the first band downlink resource and the second band uplink resource, using the transmission time difference parameter to bridge the timing gap and enable timely feedback transmission

AI summary
A method and apparatus for determining a resource position, a base station, and a storage medium are provided. The method includes: acquiring a specified transmission time difference representing a transmission time difference between a second band and a first band; determining a first resource position, which is a first-type resource position configured for a first device to transmit communication data in the first band; and determining a second resource position based on the first resource position, the specified transmission time difference, and at least one of following parameters: at least one second-type resource position of the first band or at least one second-type resource position of the second band. The second resource position is a second-type resource position configured for a second device to transmit feedback data of the communication data.
