System and Method for Guard Band Utilization for Synchronous and Asynchronous Communications

摘要

Embodiments are provided for guard band utilization for synchronous and asynchronous communications in wireless networks. A user equipment (UE) or a network component transmits symbols on data bands assigned for primary communications. The data bands are separated by a guard band having smaller bandwidth than the data bands. The UE or network component further modulates symbols for secondary communications with a spectrally contained wave form, which has a smaller bandwidth than the guard band. The spectrally contained wave form is achieved with orthogonal frequency-division multiplexing (OFDM) modulation or with joint OFDM and Offset Quadrature Amplitude Modulation (OQAM) modulation. The modulated symbols for the secondary communications are transmitted within the guard band.

1. A method of transmitting data in a data band and a guard band allocated to the data band to mitigate interference with other data bands, the method comprising:
generating a first waveform; generating a second waveform spectrally contained within the guard band; and transmitting the generated first waveform and the generated second waveform in the data band and the guard band respectively.
