Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous uplink (UL) cancellation. A method that may be performed by a user equipment (UE) includes receiving one or more configurations scheduling a communication with at least one base station (BS), wherein the one or more configurations schedule a UL transmission and a DL transmission such that the UL transmission and the DL transmission overlap in a time domain, determining whether to cancel at least a portion of the UL transmission based on one or more conditions associated with the UL transmission or the DL transmission, wherein the determination of whether to cancel at least the portion of the UL transmission is in response to the UL transmission and the DL transmission overlapping in the time domain, and performing the communication based on the determination, in accordance with aspects of the present disclosure.

Abstract: Aspects described herein relate to receiving, from a base station on a first subband of an unlicensed frequency band, control information that includes a resource allocation of an uplink transmission associated with the first UE and a demodulation reference signal (DMRS) configuration of a downlink transmission associated with a second UE. The apparatus also may obtain one or more measurements of a DMRS within channel activity on a second subband of the unlicensed frequency band using a listen-before-talk (LBT) operation based on the DMRS configuration. The apparatus also may determine whether the channel activity corresponds to the downlink transmission associated with the second UE based on the one or more measurements of the DMRS within the channel activity. The apparatus also may communicate, with the base station on the second subband, the uplink transmission when the channel activity corresponds to the downlink transmission associated with the second UE.

Abstract: Aspects of the disclosure relate to a downlink (DL) resource allocation feature in a wireless communication system, configured to address an issue that may arise in a sub-band full-duplex (SBFD) carrier (also sometimes called a flexible duplex carrier). For example, on an SBFD carrier, a slot may have a format where an uplink (UL) portion of the carrier is between two DL portions of the carrier. In a case where a scheduler operating in a New Radio (NR) network utilizes DL resource allocation of a particular type, it may arise that a portion of the DL allocation falls in the UL portion of the carrier. Accordingly, a scheduled entity may add the UL portion of the carrier to a set of resources that are indicated as not available for DL transmission. Other aspects, embodiments, and features are also claimed and described.

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: Certain aspects of the present disclosure provide techniques for channel state information measurement adaptation to maximum multiple-input multiple-output layers. A method that may be performed by a user equipment (UE) includes receiving a first channel state information (CSI) report configuration including one or more first CSI reference signal (CSI-RS) resources, wherein each first CSI-RS resource comprises a first resource set; determining, based on an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive, a first resource subset on which to report first CSI; and reporting the first CSI to a base station (BS), wherein the first CSI is based on the determined first resource subset.

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 (UE) may receive a system information block (SIB) indicating a plurality of subband configurations. The UE may identify, based at least in part on one or more of the plurality of subband configurations, one or more uplink subbands in a time division duplexing (TDD) component carrier and one or more downlink subbands in the TDD component carrier. The one or more uplink subbands and the one or more downlink subbands may be frequency division duplexed within the TDD component carrier. Numerous other aspects are provided.

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.
