Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a channel state information (CSI) report configuration associated with multiple reference signal resource sets, all reference signal resources in each reference signal resource set associated with a different base station beam, for one or more of channel measurements or interference measurements. The base station may receive a report, based at least in part on the CSI report configuration, that indicates one or more base station beams recommended for subsequent communications with a user equipment (UE). 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, from a base station, an indication of at least one first beam and at least one first antenna panel of the UE, to use for one or more first transmissions, and of at least one second beam and at least one second antenna panel of the UE, to use for one or more second transmissions. Accordingly, the UE may communicate the one or more first transmissions, with the base station, using the at least one first beam and the at least one first antenna panel. Additionally, the UE may communicate the one or more second transmissions, with the base station, using the at least one second beam and the at least one second antenna panel. Numerous other aspects are provided.

Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.

Abstract: Aspects described herein relate to communicating a beam report that includes beam measurements performed by one or more antenna panels and an identifier of the one or more antenna panels. The beam report may be used to determine a number of antenna panels supported by a user equipment (UE) transmitting the beam report, which may be used in configuring the UE for communicating with one or more other devices.

Abstract: When a beam failure is detected, appropriate actions may be taken to recover the connection. A beam failure recovery request may be sent by a user equipment (UE) apparatus to initiate the recovery of the connection. The UE detects a beam failure for at least one active downlink and uplink beam pair for full duplex communication with a secondary cell (SCell). The UE transmits a beam failure recovery request (BFRQ) for the SCell to a base station using an uplink resource of the SCell or a primary cell (PCell) based on a layer 1 signal to interference and noise ratio (L1-SINR) measurement for the at least one active downlink and uplink beam pair of the SCell.

Abstract: A User equipment (UE) receives a control resource set (CORESET) configuration for a full duplex CORESET. The UE performs a measurement for full duplex operation based on at least one of a downlink beam or an uplink beam for full duplex beam failure detection based on one or more quasi co-location (QCL) relationships to one or more transmission configuration indication (TCI) states of the CORESET based on an absence of a configuration of a reference signal for the full duplex beam failure detection.

Abstract: Methods, systems, and devices for wireless communications are described in which measurements of a number of beams that are transmitted from a first device, measured at a second device are provided in a beam switch metric report from the second device. The beam switch metric report may provide the first device with information that is otherwise unavailable to the first device and that may be used for setting beam management parameters.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving signaling configuring multiple candidate target physical cell identifiers (PCIs) of at least one candidate target cell that supports physical (PHY) layer or medium access control (MAC) layer mobility signaling, participating in a handover procedure to a target cell associated with a selected one or more of the candidate target PCIs based on PHY layer or MAC layer mobility signaling, receiving, from the target cell, a response message indicating success of the handover procedure, and terminating activity with one or more source PCIs after receiving the response message.

Abstract: Aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE receives signaling configuring multiple candidate target physical cell identifiers (PCIs) of at least one candidate target cell that support physical (PHY) layer or medium access control (MAC) layer mobility signaling. The UE participates in a handover procedure to a target cell associated with a selected one or more of the candidate target PCIs based on the PHY layer or the MAC layer mobility signaling. The UE modifies a configuration for at least one cell group (CG), wherein the one or more of the candidate target PCIs are associated with component carriers (CCs) of the at least one CG.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that activates a semi-persistent scheduling (SPS) configuration. The UE may receive SPS transmissions in a plurality of SPS occasions that are according to the SPS configuration using at least one beam that is based at least in part on: whether a scheduling offset between the DCI and the plurality of SPS occasions satisfies a threshold time duration, whether a transmission configuration indicator (TCI) state, associated with a control resource set that carries the DCI and is used to determine the at least one beam, changes while the SPS configuration is active, or whether a mapping of a TCI identifier, indicated by the DCI, to one or more TCI states changes while the SPS configuration is active. Numerous other aspects are described.
