Abstract

The present disclosure relates to a method used in a radio node, and an associated radio node. The radio node is served by a superior radio node and serves one or more subordinate radio nodes. The method includes: receiving a first synchronization signal from the superior radio node; obtaining a first downlink transmission time position for the first synchronization signal; determining a second downlink transmission time position for a second synchronization signal to be transmitted by the radio node, based on the first downlink transmission time position; and transmitting the second synchronization signal via the second downlink transmission time position to the one or more subordinate radio nodes.

Description

technical field

[0001] The techniques presented in this publication relate generally to radio communication networks. More particularly, the present disclosure relates to methods used in radio nodes and associated radio nodes. Background technique

[0002] This section is intended to provide background for various embodiments of the technology described in this disclosure. The descriptions in this section may include concepts that may be pursued, but not necessarily concepts previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and / or claims of this disclosure and is not admitted to be prior art by mere inclusion in this section.

[0003] A UE wishing to access any cell must first perform a cell search procedure. This consists of a series of synchronization phases through which the UE determines the time and frequency parameters necessary to demodulate the downlink (DL) signal a...
