Frame Structure for Filter Bank Multi-Carrier (FBMC) Waveforms

A wireless device comprising:

• a processor;
• and
• a computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• communicate a filter bank multi-carrier (FBMC) frame over an air interface of a wireless network, wherein a frame duration of the FBMC frame is an integer multiple of a duration of an orthogonal frequency division multiple access (OFDMA) frame element in an OFDMA frame communicated in the wireless network or in a neighboring wireless network.

A wireless device comprising:

• a processor;
• and
• a computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• detect a first filter bank multi-carrier (FBMC) block over a frequency resource during a first period, the first FBMC block being communicated in a wireless transmission that includes the first FBMC block and a first time window produced from circularly convolved filtering modulation of the first FBMC block;
• and
• transmit an output signal over the frequency resource during a second period, wherein the output signal includes a second FBMC block and a second time window produced from circularly convolved filtering modulation of the second FBMC block, and wherein at least a portion of the second time window and a portion of the first time window are communicated over common time-frequency resources.
