Embodiments herein disclose a method and system for designing a waveform for data communication. The method includes applying, by a phase rotation applying unit, a constellation specific phase rotation between consecutive data symbols in a data stream to obtain a constellation rotated data stream. Further, the method includes introducing, by a frequency domain pulse shaping filter, an inter symbol interference (ISI) between modulated data symbols of the constellation rotated data stream, such that the ISI develops the waveform of the constellated rotated data stream to be transmitted.

Methods and apparatuses for UE initiated reporting in a wireless communication system. A method of operating a UE includes: transmitting UE capability information supporting a FTN; generating data modulation symbols including a set of zero symbols, wherein the data modulation symbols are up-sampled or zero-padded; performing, to obtain DFT output signal, a DFT spread operation on the up-sampled or the zero-padded data modulation symbols; performing, based on a target FTN compression rate and a SC allocation, a discarding or a down sampling operation on the DFT output signal, wherein the discarding or the down sampling operation generates a subset of DFT symbols; mapping the subset of DFT symbols to a set of SCs; and performing an IFFT operation on the subset of DFT symbols to obtain an FTN-DFT-S-OFDM signal including the target FTN compression rate comprising a positive rational number smaller than one.

Systems and methods are presented for communication under strong and dynamic co-channel interference, by exploiting temporal self-coherence of complex signals transmitted within a first communication band that is equal to or falls within a second communication band occupied by co-channel interference (CCI). Each complex signal comprises a first signal and at least a second signal that is a phase-shifted replica of the first signal. The communication receiver comprises a plurality of antennas receiving each complex signal substantively under the CCI, and a Dynamic Interference Cancellation and Excision processor that excises the CCI sufficiently to demodulate each complex signal.

This application provides a signal generation method and an apparatus. In the method, a first communication apparatus generates a first signal, and sends the first signal to a second communication apparatus, who receives the first signal, and then demodulates the first signal. A symbol included in the first signal is carried on K+2(M1) subcarriers. Middle K subcarriers are valid subcarriers, start M1 subcarriers and last M1 subcarriers are redundant subcarriers, and a subcarrier spacing between adjacent subcarriers is related to a feature of a time domain pulse used to shape the subcarrier, wherein a width of each of some or all side lobes of a spectrum of the time domain pulse is equal to 1/M of a main lobe width of the time domain pulse, the subcarrier spacing is 1/M of the main lobe width. K is a positive integer, and M is a positive integer greater than 1.

An apparatus and digital signal processing means are disclosed for excision of co-channel interference from signals received in crowded or hostile environments using spatial/polarization diverse arrays, which reliably and rapidly identifies signals with transmitted features that are almost-periodic over known framing intervals, and exploits those features to develop diversity combining weights that substantively extract those signals from that environment, based on differing diversity signature, timing offset, and carrier offset of those signals. In one embodiment, the signal identification and extraction is performed in an appliqu that can be implemented without coordination with an actual radio transceiver.

A method of selectively transmitting a positioning signal from a TRP includes: transmitting, unmuted, a first intra-slot positioning signal resource segment in a first slot of a transmission schedule in accordance with a muting configuration, the transmission schedule indicating which one or more resource elements to sound for transmitting at least a portion of the positioning signal, the muting configuration indicating whether to mute intra-slot positioning signal resource segments; and muting transmission by the TRP of a second intra-slot positioning signal resource segment in the first slot of the transmission schedule in accordance with the muting configuration.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a transmitter. The transmitter receives a plurality of input bits. The transmitter encodes the plurality of input bits using a Trellis code to generate a plurality of output symbols. The Trellis code is configured to confine amplitude fluctuations between consecutive output symbols. The transmitter pulse shapes the output symbols in a frequency domain. The transmitter maps the pulse shaped symbols onto a plurality of subcarriers. The transmitter generates a time domain waveform based on the mapped symbols. The transmitter transmits the time domain waveform.

An apparatus and digital signal processing means are disclosed for excision of co-channel interference from signals received in crowded or hostile environments using spatial/polarization diverse arrays, which reliably and rapidly identifies communication signals with transmitted features that are self-coherent over known framing intervals due to known attributes of the communication network, and exploits those features to develop diversity combining weights that substantively excise that cochannel interference from those communication signals, based on differing diversity signature, timing offset, and carrier offset between the network signals and the co-channel interferers. Co-channel interference excision may be performed in an appliqu that can be implemented without coordination with a network transceiver.
