Abstract: Aspects are provided which allow for multiplexing of higher priority uplink transmissions with lower priority uplink transmissions while maintaining URLLC of the higher priority uplink transmission. A UE receives from a base station information including resources for first and second uplink data, where at least a portion of the resources for the first and second uplink data overlap in time. The first and second uplink data are associated with different priority levels. The UE determines whether to multiplex the uplink data based on a transmission timing difference between a scheduled transmission time and a multiplexed transmission time for the second uplink data on the respective resources. The base station makes a similar determination. If the transmission timing difference fails to meet a delay threshold, multiplexing is performed; otherwise, the lower priority transmission is dropped. Thus, different priority multiplexing may occur in low latency situations, satisfying URLLC.

Abstract: Various embodiments include methods for demodulating wireless transmission waveforms to reconstruct data tones, performed in receiver circuitry of a wireless communication device. The methods may include receiving time domain wireless transmission waveforms that include time domain peak reduction tones (PRTs) that were generated by a set of PRT neural networks using time domain data signals derived from frequency domain data tones in another wireless communication device, reconstructing the time domain data signals from the time domain wireless transmission waveforms using a receiver neural network that has been trained in conjunction with the set of PRT neural networks to generate a time domain reconstruction of data signals, and transforming the time domain reconstruction of data signals to a frequency domain reconstruction of data tones.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for sets of neural network weights, each set corresponding to a neural network, to one or more network entities. The one or more network entities may transmit multiple sets of neural network weights to the UE in response to the request. The UE may run a classifier neural network on the sets of neural network weights to select a set of neural network weights corresponding to a neural network. The UE may transmit a neural network identifier to the one or more network entities that transmitted neural network weights.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with a base station using an operating bandwidth part (BWP) that includes a first set of frequency resources. The UE may receive a group-common downlink control information (GC-DCI) message from the base station that includes a resource format indicator (RFI) for the UE (e.g., among multiple RFIs for a set of UEs in the GC-DCI) indicating a second set of frequency resources. The UE may modify the operating BWP based on the second set of frequency resources and communicate with the base station using the modified operating BWP. In some examples, the UE may switch the operating BWP to the second set of frequency resources or may reduce the operating BWP to a set of overlapping frequency resources between the first and second sets of frequency resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission gap for a set of transmissions including a first type of transmission and a second type of transmission based at least in part on at least one of a sounding reference signal parameter, a numerology parameter, or an antenna parameter. In some aspects, the user equipment may transmit at least one transmission, the set of transmissions, in accordance with the transmission gap for the set of transmissions based at least in part on determining the transmission gap for the set of transmissions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify two (or more) beamforming directions associated with simultaneous communications to a set of receivers. Each receiver may be associated with a different one of the two beamforming directions. The base station may schedule resources for simultaneous communications with the set of receivers based on the identified two beamforming directions. The base station may schedule simultaneous transmissions to the set of receivers using the scheduled resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station of a wireless communications system may transmit, to a user equipment (UE), a configuration message that indicates a transmission time interval (TTI) format for a plurality of TTIs. At least one format for the plurality of TTIs includes uplink resources and downlink resources separated in the frequency domain, which may be an example of a subband full duplex (SBFD) slot. Since the pattern may include some transitions between uplink and downlink resources, one or more gap periods (e.g., time gaps) may be positioned between such resources.

Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.
