Systems and methods for transmitting uplink control information, for example ACK/NACK, while in RRC_inactive state, are provided. Uplink control information is transmitted while in RRC_INACTIVE state by transmitting a sequence from a set of possible sequences to convey the uplink control information, the transmitted sequence associated with a value of the uplink control information. The sequence is asynchronously transmitted. Signalling may be used to configure a transmission resource within which to transmit the sequence, wherein the transmission resource has a time duration that is longer than a time duration to transmit the sequence. This has the effect of introducing a gap following sequence transmission that can ensure the sequence transmission does not interfere with a data transmission.

There is provided a method of transmitting and receiving data across a network. A receiver device comprises a recovery module comprising a neural network trained to recover signals from clipped signals. The transmitter device may clip the original signal more aggressively due to the improved performance of the machine-learning based recovery module, thereby reducing the Peak to Average Power Ratio (PAPR) of the signal.

The present invention is designed so that, when a CP-OFDM waveform is supported in the UL in addition to DFT-spreading OFDM waveform, transmission of UCI can still be controlled adequately. According to the present invention, a user terminal has a transmission section that transmits uplink control information (UCI), and a control section that controls transmission of the UCI based on a waveform of an uplink (UL) data channel or based on indication information provided via higher layer signaling and/or downlink control information (DCI).

A radio transmitter circuit (10) for transmitting signals within an uplink or sidelink frequency band of a cellular communications system is disclosed. It comprises a signal-generation circuit (20) configured to generate a transmission signal to be transmitted, and a radio front-end circuit (30), connected to the signal-generation circuit (20) at an input of the radio front-end circuit (30), for receiving the transmission signal, and configured to be connected to an antenna (40) at an output of the radio front-end circuit and to transmit the transmission signal to a remote node via said antenna (40). The signal-generation circuit (20) is configured to select a distortion function (D1, D2) based on a location of an allocated radio frequency resource, within said uplink or sidelink frequency band, for the transmission signal. Furthermore, the signal-generation circuit (20) is configured to generate an intermediate transmission signal, based on information to be transmitted in the transmission signal. Moreover, the signal-generation circuit (20) is configured to generate the transmission signal by applying the distortion function (D1, D2) to the intermediate transmission signal.

A transmitting device communicates with a receiving device an indication to apply PAPR reduction for a data transmission. The transmitting device applies a first PAPR reduction signal and a second PAPR reduction signal to the data transmission to reduce at least one signal peak of the data transmission to yield a transmission signal, where the first PAPR reduction signal includes a first set of PRTs that does not overlap with data tones and the second PAPR reduction includes a second set of PRTs that overlaps with the data tones and does not overlap with reserved tones. The transmitting device transmits the transmission signal to the receiving device.

A faulted message element in 5G or 6G can often be identified according to its modulation parameters, including a large deviation of the branch amplitudes from the predetermined amplitude levels of the modulation scheme, and/or the SNR of the branch amplitudes, and/or an amplitude variation of the raw signal or the branches during the message element, and/or an inconsistency between the modulation state as determined by the amplitude and phase of the raw waveform versus the amplitudes of the orthogonal branch signals, among other measures of modulation quality. An AI model may be necessary to correlate the various quality measures, and optionally to determine the correct demodulation of faulted message elements. Costly, time-consuming retransmissions may be avoided by determining the correct demodulation of each message element at the receiver, thereby improving throughput and reliability with fewer delays.

Disclosed are systems and techniques for wireless communications. For instance, a first user equipment (UE) can determine one or more parameters associated with sidelink communications between the first UE and a second UE. The first UE can determine, based on the one or more parameters, one or more non-preferred resources associated with the sidelink communications. The first UE can transmit an indication of the one or more non-preferred resources associated with the sidelink communications.

A user equipment (UE) and base station may implement improved communication methods which enable a UE that is peak current limited to perform UL transmissions which are consistent with the UL timeline. A UE that is peak current limited may utilize a new form of distributed TTI (transmit time interval) bundling for improved uplink communication performance. In performing “distributed” TTI bundling, the UE may transmit a plurality of redundancy versions of first information to the base station, wherein the plurality of redundancy versions are transmitted in non-consecutive sub-frames with a periodicity of X ms. After the plurality of redundancy versions of first information are transmitted to the base station, the base station may provide a single acknowledge/negative acknowledge (ACK/NACK) to the UE. A method for dynamically generating and using a bundle size for TTI bundling is also disclosed.

A method of operating a radio node in a wireless communication network includes communicating utilising signaling. The communication of the utilising signaling is based on performing pulse-shaping pertaining to the signaling. The pulse-shaping is based on a first pulse-shaping parameter beta. Other related devices and methods are disclosed.

Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU through a broadband from a transmission STA, and decodes the PPDU. The broadband is a 320 MHz band or a (160+160) MHz band. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained by applying a phase rotation to a sequence in which a second STF sequence for a 80 MHz band is repeated. The first STF sequence is a sequence in which a preconfigured M sequence is repeated, and is defined by a formula {M−1 −M 0 −M −1 M 0 M −1 −M 0 −M −1 M 0 −M 1 M 0 M 1 −M 0 −M 1 M 0 M 1 −M}*(1+j)/sqrt(2). A first preamble puncturing pattern includes all patterns of a band obtained by puncturing a 20 MHz band in the 320 MHz band or the (160+160) MHz band.
