AI Technical Summary

Technical Problem

Existing cellular communication systems face challenges in reducing network energy consumption by optimizing the transmission and reception of system information, particularly in scenarios where on-demand signaling is required.

Method used

A terminal device and communication method that utilizes a wake-up signal to trigger the transmission and reception of system information, where the RNTI values are incremented sequentially for efficient monitoring, allowing base stations to enter a sleep state when not in use.

Benefits of technology

This approach enables efficient on-demand transmission and reception of system information, reducing network energy consumption by minimizing unnecessary active periods of base station equipment.

Abstract

It enables efficient on-demand transmission and reception of system information. [Solution] Information indicating whether each of the multiple SSBs is transmitted and information indicating the value of RNTI For one or more SSBs that are to be received and transmitted, the values ​​are incremented sequentially from the SSB with the smallest SSB index, starting with the value indicated by the information showing the RNTI value. The RNTI determines that it is compatible, selects one of the SSBs, transmits a wake-up signal corresponding to the selected SSB, and uses the RNTI corresponding to the selected SSB to perform the operation. Monitor the response to the wake-up signal.
