Abstract: Certain aspects of the present disclosure provide techniques for downlink resource blanking. A method that may be performed by a user equipment (UE) includes receiving one or more first signals from a first cell and one or more second signals from a second cell within a sampling window, comparing a first timing of the one or more first signals with a second timing of the one or more second signals, and transmitting, to the first cell, an indication of whether to enable or disable blanking of one or more resources based on the comparison.

Abstract: Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. An aggressor BS may cause a remote interference condition for a victim BS, and the victim BS may transmit a reference signal to the aggressor BS to enable a remote interference management (RIM) operation to be performed. However, the aggressor BS may be unable to identify the victim BS based at least in part on the reference signal, and may fail to transmit a reference signal as a response. Further, when the aggressor BS does transmit a reference signal, the victim BS may be unable to identify the aggressor BS. This may reduce an effectiveness of RIM operations. In some aspects, BSs may transmit reciprocal reference signals including identification information to enable effective RIM operations.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may monitor a physical downlink control channel (PDCCH) monitoring occasion defined by an active search space (SS) set. The UE may receive, during the PDCCH monitoring occasion, a downlink control information (DCI). In response, the UE may activate at least one deactivated SS set based on the DCI and a mapping that associates an SS set to a DCI type, DCI format, transmission direction, or specific combinations thereof. In another aspect, a UE may monitor a subset less than all of PDCCH monitoring occasions defined by an active SS set. The UE may receive, during a PDCCH monitoring occasion, a DCI. In response, the UE may monitor a larger number of PDCCH monitoring occasions defined by the active SS set.

Abstract: Systems and method for providing downlink control information (DCI) sizes prioritization rules to enable a wireless network to monitor and decode a number of DCI sizes without exceeding a DCI sizes budget of a UE are disclosed. In embodiments, a UE monitors for a downlink control information (DCI) message having one of a number of different formats and one of a number of different sizes. The UE is configured with a DCI sizes budget indicating a number of different DCI sizes that the UE is configured to decode. The UE applies a DCI sizes prioritization rule to generate a prioritized set of DCI sizes. The prioritized set of DCI sizes includes a number of DCI sizes to be monitored, which is less than or equal to the DCI sizes budget. The UE decodes the DCI message based on the prioritized set of DCI sizes.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication for applying resource element (RE) skipping to a symbol where a beam change is to occur. A transmitter and a receiver determine that a beam change is to occur during the symbol. The transmitter allocates bits to a subset of REs for the symbol in a frequency domain allocation. Each RE of the subset is spaced apart by a number of empty REs. The transmitter performs an inverse fast Fourier transform (IFFT) on the REs to generate a time domain signal including a number of repetitions of a transmitted waveform. The receiver receives the time domain signal during at least a portion of the symbol. The receiver performs a fast Fourier transform (FFT) on the time domain signal and determines transmitted bits or a channel from the subset of REs output from the FFT.

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.
