Abstract: Wireless communications systems and methods related to bandwidth-efficient utilization of peak reduction tone resource are provided. An example method of wireless communications performed by a user equipment (UE) includes receiving, from a base station in a first subband, a resource allocation indicating a set of transmission tones comprising a set of first data tones, a set of second data tones and a set of peak reduction tones (PRTs). The resource allocation can indicate the set of first data tones overlaps at least a portion of the set of PRTs at respective locations of a set of PRT locations and the set of second data tones is arranged at a set of data tone locations within a particular bandwidth. The UE can communicate, with the base station in a second subband, a data transmission using an outgoing waveform based at least in part on the resource allocation.

Abstract: The apparatus of wireless communication is a UE and a base station. The UE received a control information indicating a reference signal (RS) mode for a non-coherent transmission of an UCI to the base station. The UE in the RS mode may map an RS according to an RS pattern and the UCI into resource elements assigned for a PUCCH to transmit the UCI and transmit an uplink control signal including the RS and the UCI to the base station over the PUCCH. The UE may determine a RS pattern and puncture the resource elements mapped with the code point of the UCI that corresponds to the RS pattern and map the RS based on the RS pattern. The UE may map the RS based on the RS pattern and map the code point by rate matching around the resource into which the RS is mapped.

Abstract: An apparatus is disclosed. The apparatus may determine whether one or more PUCCH resources, one or more second PUCCH resources, or one or more third PUCCH resources of a plurality of PUCCH resources are suitable for at least one uplink transmission. Each of the one or more first PUCCH resources may include a payload capacity equal to a payload threshold. Each of the one or more second PUCCH resources may include a payload capacity greater than the payload threshold. Each of the one or more third PUCCH resources may include a payload capacity less than the payload threshold. The apparatus may transmit, based on the selection of PUCCH resources, the at least one uplink transmission via the selected at least one of the one or more first PUCCH resources, the one or more second PUCCH resources, or the one or more third PUCCH resources.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may send signaling to multiple user equipments (UEs) indicating for the UEs to switch to a radio frequency bandwidth. The UEs may operate according to a reduced set of communication operations in accordance with the radio frequency bandwidth. For example, the UEs may refrain from monitoring one or more channels, may not transmit on one or more channels, or the like. The UEs may switch out of the radio frequency bandwidth based on a trigger event, such as a timer expiring, receiving an indication in a downlink control information (DCI) message, or the like.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a broadcast message via a cell associated with a network entity. The broadcast message may include an indication that the cell supports a first radio access technology (RAT) and a second RAT. In some examples, the first RAT may be associated with a first subcarrier spacing (SCS) and the second RAT may be associated with a second SCS. The UE may perform measurements of one or more reference signals associated with the first RAT based on the indication. In some examples, the one or more reference signals may be multiplexed with physical downlink shared channel (PDSCH) data. The UE may transmit a channel feedback report to the network entity based on performing measurements of the one or more reference signals, and may demodulate the PDSCH data using the first SCS and the second SCS.

Abstract: Aspects of the present disclosure provide techniques for triggering generation and transmission of a channel state information (CSI) report by the user equipment (UE) in response to issuance of at least one downlink grant by the base station. Additionally, in order to address unique challenges that may arise with respect to traffic collisions and desynchronizations based on downlink grant CSI report triggering (e.g., missing downlink control information (DCI)), aspects of the present disclosure may further implement restrictions for transmission of aperiodic CSI (A-CSI) by the UE on physical uplink control channel (PUCCH) triggered by downlink grant. Additionally, aspects of the present disclosure provide techniques for utilizing a duplicate CSI trigger indication (e.g., indicator in downlink DCI) between multiple messages in order to signal to the UE that the transmission of A-CSI may be multiplexed or merged with another uplink message (e.g., acknowledgement).

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a translational or rotational misalignment between a first antenna array of the first wireless device and a second antenna array of a second wireless device that is in line-of-sight (LoS) wireless communication with the first wireless device via a channel. The first wireless device may update a channel matrix for the channel based on the translational or rotational misalignment, where the first wireless device may update the channel matrix with one or more beam steering metrics of the first antenna array so as to improve a beam alignment between the first antenna array and the second antenna array. The first wireless device may communicate with the second wireless device in accordance with the updated channel matrix.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.
