    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.

    摘要: Embodiments are provided for pre-cancelling signal interference in Generalized Frequency Division Multiplexing (GFDM). Signal interference is pre-cancelled, at a transmitter, so that clean pilots are observed at a receiver and hence used for channel estimation. Using a Pilot-Interference Cancellation (Pilot-IC) method, interference is pre-cancelled at only pilot symbols. Alternatively, interference is simultaneously pre-cancelled at all symbols using a Transmitter IC (Tx-IC) method. The embodiments also include scattering the pilots over frequency and time resources to estimate channels which are frequency selective and time-variant. The channel estimates at the receiver are then used for single-tap channel equalization at time-frequency grid data points, where no assumption of time-invariant channels is required.

    摘要: A unified frame structure for filter bank multi-carrier (FBMC) and orthogonal frequency division multiplexed (OFDM) waveforms may allow FBMC and OFDM frames to be communicated over a common channel without significant inter-frame gaps. The unified frame structure may set an FBMC frame duration to an integer multiple of an OFDM frame element duration to enable alignment of FBMC frames and OFDM frames in the time domain. The unified frame structure may also map control channels in the FBMC and OFDM frames to common resource locations so that the respective control channels are aligned in the time and/or frequency domains. The unified frame structure may also share synchronization channels between FBMC and OFDM frames. Additionally, overhead in an FBMC time division duplexed (TDD) communications channel can be reduced by overlapping time windows appended to FBMC blocks.
