Problems solved by technology

However, in IDLE state or INACTIVE state uplink positioning, there is no connection between the terminal and the network. In this case, it is impossible to determine whether the uplink synchronization between the terminal and the network in the uplink positioning mechanism is maintained and how to ensure it when the uplink is out of sync. Continue to ensure the reliable transmission of SRS

Abstract

The present disclosure relates to the field of communications, and discloses a synchronization state processing method and device, and a storage medium, the method comprising: in a process in which a terminal in an IDLE state or an INACTIVE state transmits an SRS to a base station to perform uplink positioning, the terminal or the base station can obtain channel state information of a transmission channel between the terminal and the base station, according to the method, the terminal and the base station, the synchronization state between the terminal and the base station which are in IDLE state or INACTIVE state uplink positioning is detected based on the channel state information, and when uplink out-of-step is detected, the terminal or the base station can adopt a corresponding processing way to continue to guarantee the subsequent IDLE / INACTIVE positioning process.

Description

technical field [0001] The present application relates to communication technologies, and in particular, to a synchronization state processing method, device and storage medium. Background technique [0002] Uplink synchronization refers to the process in which the uplink signals of each terminal in different locations using the same time slot in a cell reach the receiving antenna of the base station at the same time, that is, the signals of different terminals in the same time slot are kept synchronized when they reach the receiving antenna of the base station. Uplink multiple access interference and multipath interference between cell terminals increase cell capacity and cell radius. [0003] When not accessing the network, the terminal can only establish a connection with the network by initiating a random access (Random Access Channel, RACH) process, and realize uplink synchronization in the process. After the terminal accesses the network, the base station can determin...
