Section: 6.11.1.2 Mapping to resource elements
Content: The mapping of the sequence to resource elements depends on the frame structure. The UE shall not assume that the primary synchronization signal is transmitted on the same antenna port as any of the downlink reference signals. The UE shall not assume that any transmission instance of the primary synchronization signal is transmitted on the same antenna port, or ports, used for any other transmission instance of the primary synchronization signal. The sequence shall be mapped to the resource elements according to For frame structure type 1, the primary synchronization signal shall be mapped to the last OFDM symbol in slots 0 and 10. For frame structure type 2, the primary synchronization signal shall be mapped to the third OFDM symbol in subframes 1 and 6. Resource elements in the OFDM symbols used for transmission of the primary synchronization signal where are reserved and not used for transmission of the primary synchronization signal. For frame structure type 3, the primary synchronization signal shall be mapped according to frame structure type 1 with the following exceptions: - the primary synchronization signal shall be transmitted only if the corresponding subframe is non-empty and at least 12 OFDM symbols are transmitted, - a primary synchronization signal being part of a discovery signal shall be transmitted in the last OFDM symbol of the first slot of a discovery signal occasion. For an MBMS-dedicated cell, the primary synchronization signal shall be mapped according to frame structure type 1 with following exception: - the primary synchronization signal shall be transmitted in slot 0 in subframes fulfilling only,
