SYSTEM AND METHOD OF WAVEFORM DESIGN FOR OPERATION BANDWIDTH EXTENSION

Title:

SYSTEM AND METHOD OF WAVEFORM DESIGN FOR OPERATION BANDWIDTH EXTENSION

Document Type and Number:

WIPO Patent Application WO/2016/155530

Kind Code:

A1

Abstract:

Different numerologies may be used to communicate orthogonal frequency division multiplexing (OFDM) -based signals over different frequency sub-bands of a given carrier. This may allow the OFDM-based signals to efficiently support diverse traffic types. In some embodiments, the numerology of OFDM-based signal depends on a bandwidth of the frequency sub-band over which the OFDM-based signals are transmitted. In some embodiments, the OFDM-based signals are filtered OFDM (f-OFDM) signals, and the pulse shaping digital filter used to generate the f-OFDM signals allows the receiver to mitigate interference between adjacent f-OFDM signals upon reception, thereby allowing f-OFDM signals to be communicated over consecutive carriers without relying on a guard band.
