Reference-Signal Coordination for Base-Station Communication Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, independent operation of RFID readers affects communication performance due to resource conflicts and interference between different base stations.
Innovation Solution
Implement coordinated network behaviors by using reference signals for resource allocation and interference management between network devices, allowing shared or orthogonal resource utilization without affecting communication quality.

Engineering Contradiction Analysis
1Ease of operation
If different base stations communicate with tag devices independently, then each base station can operate autonomously, but resource conflicts and interference occur between base stations
Solution Approach 1:
The patent merges the autonomous operation of individual base stations with coordinated resource management by introducing a reference signal mechanism. Each base station still operates independently to send reference signals, but these signals are coordinated to enable resource allocation decisions that prevent conflicts and interference, thus combining autonomy with cooperation.
Solution Approach 2:
The patent implements feedback through the reference signal measurement mechanism. Base stations send reference signals, terminal devices measure these signals and report measurement results, and network devices use this feedback information to determine resource allocation that avoids interference while maintaining autonomous operation.
2Reliability
If reference signals are sent frequently to enable coordinated resource allocation, then communication performance improves, but system complexity increases
Solution Approach 1:
The patent makes the reference signal multi-functional by having it serve both as a coordination mechanism for resource allocation and as part of the existing signal infrastructure. This universality reduces the need for separate dedicated signals, thereby limiting the increase in system complexity while maintaining communication performance benefits.

AI summary
This application relates to the field of communication technologies, and provides a communication method and apparatus. The method includes: A first network device sends at least one reference signal to a second network device, to receive a measurement result of the second network device on the at least one reference signal; and the first network device determines, based on the measurement result, at least one resource for communication with at least one terminal device. According to the method, the first network device determines, by using the measurement result of the second network device on the reference signal, the resource used for communication between the first network device and the terminal device, thereby coordinating network behaviors of different network devices, avoiding a conflict between resources used by different network devices, improving network reliability, and improving communication performance.
