Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network entity may indicate, to a first UE and a second UE, transmission parameters of a multi-port CLI-reference signal (CLI-RS) that is associated with estimation of CLI channel between the first UE and the second UE. The network entity may indicate, to the first UE, one or more precoding parameters associated with uplink precoding at the second UE. The second UE may transmit the multi-port CLI-RS to the first UE, and the network entity may transmit a CSI-reference signal (CSI-RS) to the first UE. The first UE may transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the one or more precoding parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on a precoded cross link interference (CLI) channel at the UE. For example, a network entity may transmit a control message to a first UE that indicates a reporting configuration for indicating CSI associated with a channel between the first UE and the network entity. The first UE may generate the CSI based on a precoded CLI channel at the first UE associated with at least one uplink transmission associated with a second UE, where the precoded CLI channel is generated using at least one estimated CLI channel associated with the at least one uplink transmission and at least one candidate precoding matrix associated with the second UE. In accordance with the reporting configuration, the first UE may transmit the CSI to the network entity.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive downlink control information (DCI) comprising an indication of a bandwidth part (BWP) switch for a secondary cell to a dormant BWP and transition the secondary cell from an active state to a dormant state based on the indication of the BWP switch of the secondary cell to a dormant BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message to a base station, the UE capability message including an indication of a UE type, wherein the UE type is associated with at least one of a reduced bandwidth, or a reduced number of antennas, or a combination thereof for the UE. The UE may receive, based at least in part on the UE capability message, a downlink grant for downlink resources for a data transmission in accordance with a resource allocation scheme, wherein the resource allocation scheme is associated with the UE type and a supported bandwidth part of the UE. The UE may monitor a wireless channel based at least in part on the downlink grant. The UE may receive the data transmission based at least in part on the monitoring of the wireless channel.

Abstract: Certain aspects of the present disclosure provide techniques for PEI location determination. According to certain aspects, a method of wireless communication by a user equipment (UE) includes receiving, from a network entity, a configuration of a paging early indication (PEI) that indicates, for multiple paging occasions (POs) in multiple paging frames (PFs), whether paging physical downlink control channels (PDCCHs) are scheduled in the multiple POs, identifying a reference PF from one of the multiple PFs, and monitoring for the PEI in a location of a PEI occasion determined based on the reference PF and at least one timing offset.

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: 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: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving one or more first messages that indicate one or more configurations for communications between the UE and a network entity during a plurality of periodic communication occasions. The method may also include receiving a control message that activates at least one of the one or more configurations and schedules multiple instances of the communications. Upon receiving the control message, the UE may communicate the multiple instances in accordance with the at least one of the one or more configurations, each of the multiple instances including a different set of transport blocks.
