Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a capability of the UE is sufficient for a make-before-break (MBB) handover from a source set of cells to a target set of cells, wherein the source set of cells is provided by a first set of transmit/receive points (TRPs) and the target set of cells is provided by a second set of TRPs; and selectively perform the MBB handover using a first capability configuration for the MBB handover or a second capability configuration for the MBB handover based at least in part on whether the capability of the UE is sufficient for the MBB handover. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for beam management for make-before-break (MBB) handover. A method that may be performed by a user equipment (UE) includes establishing a first cell connection with a first base station (BS) while maintaining an existing second cell connection with a second BS, and determining that a first transmission time of a first signal transmitted by the first BS is less than a threshold time duration from a second transmission time of a second signal transmitted by the second BS. In some examples, the first signal is associated with one or more first communication metrics and the second signal is associated with one or more second communication metrics, wherein each of the one or more first communication metrics and the one or more second communication metrics comprise one or more quality of service (QoS) metrics.

Abstract: Aspects described herein relate to receiving, from a serving cell, a configuration for performing conditional handover to one or more target cells, establishing, based on detecting a condition from the configuration, a connection with a target cell for performing handover to the target cell, and transmitting, based on establishing the connection with the target cell and based on determining that the conditional handover is of a type where a source connection with the source cell remains, a notification to the serving cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an activation status message identifying one or more transmission configuration indicator (TCI) states or one or more spatial relationships, the activation status message being configured to alter one or more activation statuses for the one or more TCI states or the one or more spatial relationships in a single bandwidth part associated with a single component carrier; and selectively alter the one or more activation statuses of the one or more TCI states or the one or more spatial relationships in a plurality of bandwidth parts associated with a plurality of component carriers based at least in part on receiving the activation status message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam failure recovery scheduling request (BFR-SR) to a primary cell or a primary secondary cell base station based at least in part on detecting a beam failure associated with a secondary cell (SCell) link between the UE and an SCell base station. The UE may start a timer based at least in part on transmitting the BFR-SR. The UE may retransmit the BFR-SR based at least in part on the timer expiring prior to the UE receiving a response to acknowledge the BFR-SR and schedule transmission of a medium access control (MAC) control element (MAC-CE) including information to recover from the beam failure and/or the timer expiring prior to the UE transmitting the MAC-CE. Numerous other aspects are provided.

Abstract: Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule sounding operations by the wireless nodes (e.g., access points and/or stations) operating within the cluster.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure, before transmitting a physical downlink shared channel communication, a first resource and a second resource. The BS may transmit the physical downlink shared channel communication using the first resource. The BS may selectively use, after transmitting the physical downlink shared channel communication, the second resource for the reference signal transmission for subband selection and beam selection based at least in part on whether a retransmission event is detected. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method determines resources to monitor for beam failure detection (BFD) when the UE is in a mode of operation involving at least first and second transmitter receiver points (TRPs). The method then detects a beam failure based on monitoring of the determined resources. The method further triggers a beam failure recovery (BFR) procedure based on the detection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment (UE), a message that indicates whether the UE received a downlink transmission from the base station in a first frequency range. The base station may schedule one or more reference signal (RS) transmissions in the first frequency range and one or more RS transmissions in a second frequency range based at least in part on the message received from the UE, and reschedule the downlink transmission on a component carrier in either the first frequency range or the second frequency range based at least in part on channel quality information that is determined from the one or more RS transmissions in the first frequency range and the one or more RS transmissions in the second frequency range. Numerous other aspects are provided.
