摘要： The present invention relates to a multicarrier waveform-based system for mitigating inter- numerology interference, wherein at least one subcarrier signal of a first numerology designated as at least one interfering subcarrier signal interferes with at least another subcarrier signal of a second numerology designated as at least one interfered subcarrier signal, the first numerology being different from the second numerology. The system is configured to comprise a transmitter and a receiver communicating via a communication channel. The system is also configured to match an interference from the at least one interfering subcarrier signal to the at least one interfered subcarrier signal by matching frequency domain data symbols of the at least one interfering subcarrier signal to frequency domain data symbols of the at least one interfered subcarrier signal through a respective interference coefficient matrix with respect to the frequency domain data symbols of the at least one interfering subcarrier signal.

摘要： Systems, methods, and instrumentalities are disclosed for separating a channel and data without the use of reference signals. For example, a wireless transmit/receive unit (WTRU) may determine a first orthogonal frequency-division multiplexing (OFDM) symbol based on a data vector. The WTRU may determine a second OFDM symbol by applying a circular time-inverse operation and a conjugate operation to the first OFDM symbol. The WTRU may send the first OFDM symbol and the second OFDM symbol. The first and the second OFDM symbols may be sent to consecutively. Discrete Fourier Transform (DFT)- spread and nonlinear preprocessing (exponential transformation at the transmitter) may be used and/or peak-to-average power ratio (PAPR) may be reduced via randomizer block at the receiver.

摘要： Multi-band OFDM transmission with overlapping bands. Each band has a different carrier frequency but the bandwidths overlap each other. In time domain, the modulated carriers of each band are set to zero during so-called free time periods within the carrier period except one carrier which is sampled and decoded during this free time period. Successive Interference Cancellation (subtraction of a remodulated replica) is performed, and then the next band can be decoded and so on. In order that the samples at the receiver all fall within the free time periods, the sampling frequency must be aligned with the carrier period, it is therefore proposed there for a sampling frequency not coinciding with a multiple of the carrier frequency to truncate said carrier. FFT is then performed on each separated band.
摘要翻译：具有重叠频带的多频带OFDM传输。每个频带具有不同的载波频率，但带宽彼此重叠。在时域中，除了在该空闲时间段内进行采样和解码的一个载波之外，在载波周期期间的所谓的空闲时段期间，每个频带的调制载波被设置为零。连续干扰消除（减去重调制的副本），然后可以对下一个频带进行解码等等。为了使接收机的采样全部落入空闲时间段内，采样频率必须与载波周期对齐，因此提出了与载波频率的倍数不一致的采样频率来截断所述载波。然后对每个分离的频带执行FFT。

摘要： Devices and methods are disclosed for generating, filtering, and amplifying signals that are sent and received using SOCs. These improved methods and devices advantageously provide filtering of composite RF signals such that the RF signals can be transmitted with an improved SNR. Such filtered signals can then be transmitted at a higher power. Because filtering is performed at an intermediate frequency, the higher cost of low-noise RF-transmitters and/or RF filtering components can be avoided. Accordingly, less expensive (e.g., noisier) components, such as readily available wireless transceiver SOCs, can be used for generating RF signals, filtering the signals, and then transmitting the filtered signals at higher power. As a result of these devices and methods, inexpensive SOCs may be used at higher powers and over longer ranges than would be normally expected
摘要翻译：公开了用于生成，过滤和放大使用SOC发送和接收的信号的设备和方法。这些改进的方法和设备有利地提供复合RF信号的滤波，使得RF信号可以以改进的SNR传输。然后可以以更高的功率传输这种滤波的信号。因为滤波是在中频处进行的，所以可以避免较高成本的低噪声RF发射器和/或RF滤波元件。因此，可以使用较便宜的（例如更噪声的）部件（例如容易获得的无线收发器SOC）来生成RF信号，对信号进行滤波，然后以更高的功率来发送滤波后的信号。作为这些设备和方法的结果，可以以比通常预期更高的功率和更长的范围使用廉价的SOC
