AI Technical Summary

Technical Problem

In wireless communication systems, existing technologies struggle to effectively manage low-level triggered mobility processes between base stations, especially during handover between base stations. The inability to determine the timing advance of candidate cells and the lack of Layer 2 reset information leads to mobility delays and inefficiencies.

Method used

A base station device and method are provided to obtain the timing advance and no-layer 2 reset information of candidate cells by transmitting request messages, so as to ensure accurate configuration of the TA ID and no-reset ID measured by the UE during the handover process, and realize coordination and information transmission between base stations.

Benefits of technology

It improves the efficiency and accuracy of handover between base stations, reduces mobility latency, and ensures the stability and performance of wireless communication systems.

Abstract

Embodiments of the present disclosure relate to methods and apparatuses for L2 reset indication and TA indication for UE measurement in LTM scenarios. According to some embodiments of the present disclosure, a first BS can: transmit a request message to a second BS, wherein the request message includes an identification of a first candidate cell and an indication of whether a TA requested UE measurement can be used or an indication of whether a cell handover without L2 reset is performed when handover from a second candidate cell to the first candidate cell; and receive a response message from the second BS in response to the request message.
