    Abstract: 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.

    Abstract: A transmitter adapted for massive multiple-input multiple-output (M-MIMO) operation includes a first set of power amplifiers (PAs) that amplifies a first signal to produce an amplified first signal, and a second set of PAs that amplifies a second signal to produce an amplified second signal, wherein PAs in the first set of PAs are different from PAs in the second set of PAs. The transmitter includes an antenna array operatively coupled to the first set of PAs and the set of second PAs, the antenna array including a plurality of transmit antennas, wherein the antenna array transmits one or more of the amplified signals.
