User Equipment, Radio Network Node and Methods for Managing Synchronization Signals

A method performed by a user equipment, UE, for handling synchronization signals, from a radio network node in a wireless communication network, the method comprising:

• receiving a non-cell defining, non-CD, synchronization signal, and one or more cell defining, CD, synchronization signals;
• decoding the non-CD synchronization signal to determine a first cell identity value associated to the non-CD synchronization signal;
• decoding the one or more CD synchronization signals to determine one or more second cell identity values associated to the one or more CD synchronization signals;
• and
• determining whether the non-CD-synchronization signal is associated with at least one CD-synchronization signal, and thereby transmitted from a same radio network node, based on the first cell identity value and the one or more second cell identity values.

A radio network node for managing synchronization signals in a wireless communication network, wherein the radio network node is configured to:

• determine a first cell identity value for a non-cell defining, non-CD, synchronization signal, wherein the first cell identity value is determined as a function of a second cell identity value of a cell defining, CD, synchronization signal transmitted by the radio network node;
• configure the non-CD synchronization signal based on said determined first cell identity value;
• and
• transmit the non-CD synchronization signal as configured.
