摘要： Methods and systems for signal transmission in millimeter wave (mmW) range. A set of sequences is used to encode a data signal for one layer in a group of layers. Each sequence in the set of sequences has a length equal to the number of resources shared among the group of layers. At least a portion of the sequences have a low density of non-zero values, and the non-zero values are assigned to a subset of the shared resources. Each sequence assigns a non-zero value to at most one resource of the subset of shared resources, and all non-zero values assigned by all sequences have equal power amplitudes.

摘要： The present invention relates to a method for transmitting multiple communications of different types, in particular sporadic (MTC) or cellular (broadband) communication comprising symbols to be transmitted, corresponding to communication services implementing a modulation having M subcarriers of the FBMC-OQAM or OFDM-OQAM type. The method uses linear frequency filtering of a sequence of length N including symbols having L coefficients that are parametrizable according to the communication,
L ,
N , and M being natural numbers, so as to generate
N +
L - 1 symbols, reducing out-of-band spurious emissions. Said method also uses, no matter what the communication is, a single frequency/time transform (IFFT) having a size
M , where
N M . Indeed for sporadic communications (MTC) in a lower frequency band, the constraints on the out-of-band side-lobes are more stringent on the filter and FBMC modulation is thus better adapted.

摘要： 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.

摘要： The present invention relates to a method for conditioning a multi-carrier signal for data transmission in a telecommunication network. At least one data symbol is modulated onto one or more subcarriers in a frequency block for data transmission, the subcarriers being separated from each other in frequency domain by a predetermined subcarrier spacing. Additionally, at least one cancellation symbol is modulated onto one or more frequencies at frequency positions outside the frequency block, and separated from subcarriers therein by a non-integer multiple of the predetermined subcarrier spacing for partial cancellation of one or more side lobes originating from transmission of the at least one data symbol. The modulated at least one data symbol and the modulated at least one cancellation symbol are then converted from frequency-domain to time domain to form respective time domain signals. Finally, the respective time domain signals are combined to form the multi-carrier signal for transmission.

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.
