Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits a DSS capability indication to a network entity (e.g., base station), which determines scheduling information for resources of a DSS carrier based on the DSS capability indication. In another aspect, a BS transmits RAT-specific (e.g., LTE-specific) information associated with a DL RS (e.g., LTE CRS) to a UE, which processes the DL RS on a DSS carrier based at least in part on the RAT-specific information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a radio resource control (RRC) configuration with one or more high layer parameters that enable one or more of an aperiodic sounding reference signal (SRS) triggering without data scheduling or a secondary cell (SCell) dormancy indication using downlink control information (DCI). The UE may receive, from the base station and based at least in part on the RRC configuration, DCI that is associated with at least one of: the aperiodic SRS triggering without data scheduling or the SCell dormancy indication. The UE may transmit, to the base station, an aperiodic SRS based at least in part on the DCI that triggers the aperiodic SRS. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration for UE paging is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a paging communication. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE in a sidelink communication with the first UE, an indication to switch from utilizing a first sidelink bandwidth part (SL-BWP) to utilizing a second SL-BWP. The UE may selectively switch from utilizing the first SL-BWP to utilizing the second SL-BWP based at least in part on receiving a positive acknowledgment message from the second UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting demodulation reference signals (DMRS) with control channels (e.g., physical downlink control channels (PDCCHs)) that enable receiving devices to bundle (e.g., coherently combine) the DMRS over time. A UE may detect a portion of a PDCCH to the UE in at least one resource element group (REG), wherein the REG is in a segment of a control resource set (CORESET) configured for the UE or a group of UEs including the UE and the REG is during a first search space (SS) set occasion configured for the UE or the group of UEs; and process wideband (WB) DMRS in the segment during the first SS set occasion and in the segment during at least one second SS set occasion, wherein the UE does not detect another portion of the PDCCH or another PDCCH during the second SS set occasion.

Abstract: A configuration for a UE that measures CLI to determine the reception timing of the CLI signal transmitted from a UE in another cell. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of measuring CLI signals by improving the manner in which a wireless device determines the reception timing of a transmitted CLI signal. An apparatus receives a first downlink signal from a first base station. The apparatus receiving a second downlink signal from a second base station. The apparatus determines a CLI signal measurement from a second UE received at the first UE based on a propagation delay difference, the propagation delay difference being based on the first downlink signal and the second downlink signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for a first cell, wherein the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. A first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.
