Synchronization in a flexible bandwidth wireless network

A user equipment comprising:

• a receiver;
• and
• a processor;
• wherein:
• the receiver and the processor are configured to process signals in a first bandwidth, the processed signals including a primary synchronization signal and a secondary synchronization signal;
• the processor is configured to determine a cell bandwidth from an indication of the cell bandwidth included in at least one of the processed signals in the first bandwidth, wherein the cell bandwidth has a larger bandwidth than the first bandwidth and the first bandwidth is a portion of the cell bandwidth;
• and
• the processor and the receiver are configured to receive signals in the cell bandwidth including signals having at a least a portion of those signals' bandwidth outside of the first bandwidth.

A method comprising:

• processing, by a user equipment, signals in a first bandwidth, the processed signals including a primary synchronization signal and a secondary synchronization signal;
• determining, by the user equipment, a cell bandwidth from an indication of the cell bandwidth included in at least one of the processed signals in the first bandwidth, wherein the cell bandwidth has a larger bandwidth than the first bandwidth and the first bandwidth is a portion of the cell bandwidth;
• and
• receiving, by the user equipment, signals in the cell bandwidth including signals having at a least a portion of those signals' bandwidth outside of the first bandwidth.

A base station comprising:

• a transmitter;
• and
• a processor;
• wherein:
• the transmitter and the processor are configured to transmit, in a first bandwidth, signals including a primary synchronization signal and a secondary synchronization signal, wherein the signals in the first bandwidth include an indication of the cell bandwidth, wherein the cell bandwidth has a larger bandwidth than the first bandwidth and the first bandwidth is a portion of the cell bandwidth;
• and
• the transmitter and the processor are configured to transmit signals in the cell bandwidth including signals having at a least a portion of those signals' bandwidth outside of the first bandwidth.
