AI Technical Summary

Technical Problem

Existing antenna calibration techniques can cause data communication interruptions when injecting signals, affecting control and data channels. In particular, the increased symbol usage during multi-antenna branch calibration impacts services in LTE and NR spectrum sharing modes.

Method used

By flexibly allocating the time and frequency resources of antenna calibration signals, the injected signals are separated to reduce the impact on services, and phase and amplitude drift are calibrated by overlapping frequency resource blocks, reducing processing load and storage usage.

Benefits of technology

This reduces the impact of antenna calibration on services, decreases the amount of time and frequency resources occupied by the signal, and reduces processing load and storage requirements.
