Abstract: A UE may receive DCI from a first TRP scheduling a transmission of a TB from the first TRP and a second TRP. The UE may receive, from the first TRP a first set of CBGs of the TB in a first set of resources. The UE may receive, from the second TRP a second set of CBGs of the TB in a second set of resources that is different than the first set of resources. The first set of CBGs may be received based on a first MCS and the second set of CBGs may be received based on a second MCS. The UE may transmit, in a full-duplex mode, a message to the first TRP. The transmission to the first TRP may overlap in time with the reception from the first TRP. Accordingly, the first MCS may be lower than the second MCS.

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: An apparatus may utilize an air interface to transmit and/or receive a transmission during a first TTI that includes a second set of data overriding a first set of data scheduled for transmission during the first TTI. The air interface may further be utilized to transmit and/or receive a transmission after a duration of time that is less than a total time duration of the first TTI that includes an override indicator that is at least partially embedded in a data portion of a subframe. The override indicator may be configured to indicate that the first set of data scheduled for transmission during the first TTI is overridden by the second set of data having the higher priority. The override indicator may be transmitted after the second set of data is transmitted. The one or more additional TTIs may be after the first TTI.

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 user equipment (UE) may identify one or more radio frequency (RF) spectrum bands for full-duplex communications, and may signal an indication of the UE's capability to support full-duplex communications for each RF spectrum band. The UE may further receive one or more configurations for full-duplex communications, which, in some examples, may be based on the UE's indicated capabilities. As an example, the UE may identify a guard band configuration for full-duplex communications, where the guard band configuration may be based on one or more aspects of resources used for the full-duplex communications. In other cases, the UE may identify a transmission hopping or antenna switching configuration for full-duplex communications. In any case, the UE may communicate with a base station in accordance with the one or more configurations and the UE's capabilities.

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: Aspects of the disclosure relate to selection and use of peak reduction tones (PRTs) including obtaining a predetermined sequence of PRTs corresponding to a set of granted resources including a plurality of tones, mapping a set of data to a first subset of the plurality of tones outside of the predetermined sequence of PRTs and mapping a set of PRTs to a second subset of the plurality of tones within the predetermined sequence of PRTs. At least one peak of a time domain representation of the first subset of the plurality of tones is canceled using a time domain representation of the second subset of the plurality of tones. A transmitted waveform comprising the first subset of the plurality of tones and the second subset of the plurality of tones is transmitted.

Abstract: Aspects presented herein may enable a wireless device to use periodic reserved resources to serve aperiodic traffic over sidelink. In one aspect, a wireless device reserves a set of periodic resources for sidelink transmission, where the reserved set of periodic resources include reserved resources for SCI and reserved resources for data. The wireless device transmits SCI without a data transmission in a periodic resource for the period. In another aspect, a first wireless device receives a reservation from a second wireless device for a set of periodic resources for sidelink transmission. The first wireless device receives, from the second wireless device, SCI in a period of the periodic resources, the SCI including an indication that the SCI is not associated with a data transmission.

Abstract: 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.
