Abstract: In an embodiment, a base station determines a spatial relationship for a group of PUCCH resources, and transmits a control message that indicates the spatial relationship to a UE. The UE receives the control message and stores an indication of the spatial relationship. In some designs, the control message conveying the spatial relationship identifies the group of PUCCH resources via the PUCCH group index, while in other designs a different identification mechanism may be used. In another embodiment, a base station determines an association between a group of PUCCH resources and a PUCCH group index, and transmits a control message that indicates the association to a UE. The UE receives the control message and stores an indication of the association.

Abstract: Certain aspects of the present disclosure provide techniques for configuring reference signals. A method that may be performed by a user equipment (UE) includes receiving a control message indicating a first quasi co-location (QCL) for an aperiodic-tracking reference signal (A-TRS), the A-TRS being associated with a periodic-tracking reference signal (P-TRS), determining a second QCL for the P-TRS based on the first QCL for the A-TRS, setting a receive beam for reception of the P-TRS based on the second QCL of the P-TRS, and decoding one or more frames based on channel statistics estimated via the P-TRS received via the receive beam.

Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation. The MPUE may have at least an active first panel and an inactive second panel. The MPUE may determine to activate the second panel. The MPUE may activate the second panel in response to the determination. The MPUE may transmit, from the active first panel to a base station, a status indicating that the second panel is active. The MPUE may transmit, after an activation time, an uplink transmission from the second panel to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station (BS), a handover message or the beam or panel selection message including multi-beam or multi-panel information identifying a first one or more beams or panels to remain with the source BS and a second one or more beams or panels to switch from the source BS to a target BS during a handover procedure. The UE may perform the handover procedure to switch from the source BS to the target BS with the first one or more beams or panels for communication with the source BS and the second one or more beams or panels for communication with the target BS. 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 information identifying a virtual control resource set (CORESET) or a virtual search space for a semi-persistently scheduled shared channel. The UE may receive the semi-persistently scheduled shared channel using a default beam that is selected based at least in part on the virtual CORESET or the virtual search space. 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 a downlink beam indication for at least one of a channel, a resource, a resource set, a bandwidth part, or a component carrier; and use the downlink beam indication for a group of channels, resources, resource sets, bandwidth parts, or component carriers. In some aspects, a UE may receive an indication of a spatial relation and multiple physical uplink control channel (PUCCH) resources to which the spatial relation is to be applied; and use the spatial relation to transmit on one or more PUCCH resources of the multiple PUCCH resources. 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 configuring a media access control (MAC)-control element (CE) to update a sounding reference signal (SRS) beam within a wireless communication system. Other aspects described herein relate to configuring default beam information for determining a beam for data channel communications within the wireless communication system. A user equipment (UE) or other device can determine to use the default beam information for configuring the beam for a data channel communication and for performing power control using, e.g., physical uplink shared channel (PUSCH) parameters. In addition, in some examples, the device can transmit the data channel communication using a beam configured based on the default beam information.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a characteristic of a first beam associated with a first antenna array, determine a second beam associated with a second antenna array as a quasi-co-located beam with respect to the first beam based on the characteristic, and communicate on the first and second beams based on the determining. A base station may identify a user equipment (UE) searching for a connection with a secondary cell on a second frequency band, wherein the UE is served by the base station on a first frequency band and transmit an indicator to the UE to inform the UE regarding selection of a particular beam for measuring a reference signal from the secondary cell.

Abstract: Aspects of the present disclosure provide various apparatuses and methods for extending a reference signal to facilitate carrier aggregation (CA). In some examples, a network includes a primary cell and one or more secondary cells that use a millimeter wave (mmW) carrier. When a UE is beyond the range of a reference signal from the secondary cell, the primary cell may trigger the secondary cell to increase the range of its reference signal using a higher gain beam and/or reference signal repetition.
