Method and apparatus for implementing reference signal transmissions in a wireless communication system

A network node for transmitting System Frame Number (SFN) in a cell controlled by the network node in a wireless communication system in which transmissions are organized into radio frames and one radio frame contains multiple subframes, comprising:

• a control circuit;
• a processor installed in the control circuit;
• and
• a memory installed in the control circuit and operatively coupled to the processor (308);
• wherein that the processor is configured to execute a program code stored in the memory to:
• broadcast, by the network node, a synchronization signal in an Orthogonal Frequency Division Multiplexing (OFDM), symbol of a subframe;
• and
• broadcast, by the network node, a signaling indicating the SFN of the cell in multiple OFDM symbols of the subframe, wherein the multiple OFDM symbols include the OFDM symbol used for broadcasting the synchronization signal.

A User Equipment (UE) for receiving System Frame Number (SFN) in a cell in a wireless communication system in which transmissions are organized into radio frames and one radio frame contains multiple subframes, comprising:

• a control circuit;
• a processor installed in the control circuit;
• and
• a memory installed in the control circuit and operatively coupled to the processor;
• wherein that the processor is configured to execute a program code stored in the memory to:
• receive, by the UE, a broadcasted synchronization signal in an Orthogonal Frequency Division Multiplexing (OFDM), symbol of a subframe;
• and
• receive, by the UE, a broadcasted signaling indicating the SFN of the cell in multiple OFDM symbols of the subframe, wherein the multiple OFDM symbols include the OFDM symbol used for receiving the synchronization signal.
