Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a control resource set (CORESET) is not configured for an active downlink bandwidth part of a component carrier (CC) of the UE. The UE may determine that a transmission configuration indication (TCI) state is not activated for a physical downlink shared channel (PDSCH) of the active downlink bandwidth part of the CC. The UE may determine a default spatial relation for an uplink control channel or uplink signal for the CC based at least in part on determining that the CORESET is not configured for the active downlink bandwidth part of the CC and that the TCI state is not activated for the PDSCH of the active downlink bandwidth part of the CC. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which spatial relations for one or more uplink reference signal transmissions, such as sounding reference signal (SRS) transmissions, may be configured and a particular spatial relation indicated in a medium access control (MAC) control element (CE). A base station may configure a pool of available spatial relations for use in SRS transmissions, and the MAC-CE may indicate which spatial relation of the set of available spatial relations is to be used. In other cases, the MAC-CE may provide all of the spatial relation information for an associated SRS transmission. The UE, responsive to receiving the MAC-CE, may transmit a SRS to the base station using the indicated spatial relation.

Abstract: Wireless communications systems and methods related to handling link failures in a first cell and a second cell are provided. A wireless communication device can detect a first link failure associated with a first cell and can detect a second link failure associated with a second cell. Additionally, the wireless communication device can perform a link failure recovery procedure. This may include prioritizing a first link failure recovery for the first cell over a second link failure recovery for the second cell. Other aspects and features are also claimed and described.

Abstract: Apparatus, methods, and computer-readable media for facilitating relayed uplink transmissions are disclosed herein. An example method for wireless communication at a first device includes receiving an uplink transmission from a second device. The example method also includes relaying the uplink transmission to a base station, and providing an indication that the second device is an originating source of the uplink transmission when relaying the uplink transmission to the base station.

Abstract: The present disclosure provides signaling for user equipment (UE) panel identification. The UE may have at least a first panel and a second panel. The UE may receive at least one downlink reference signal from a base station. The UE may determine a first mapping of the at least one downlink reference signal to one or more panel identifiers. The UE may receive a configuration of an uplink reference signal resource. Based on the configuration, the UE may transmit an uplink reference signal using a selected panel, the selected panel being associated with a selected panel identifier. The UE may transmit a report including a second mapping between the selected panel identifier and the uplink reference signal. The UE may receive an uplink grant indicating the selected panel associated with the selected panel identifier. The UE may transmit an uplink data channel using the selected panel.

Abstract: Methods, systems, and devices for wireless communications are described that allow secondary cell (SCell) beam failure recovery using a primary cell (PCell). A user equipment (UE) may transmit, via the PCell, an indication of a beam failure of the SCell in a scheduling request (SR) or in a dedicated SR message. After receiving the indication, the base station may request a report from the UE or alternatively, may monitor a set of resources for a report without transmitting a request to the UE. The report may be transmitted via the PCell and may include an indication of a selected beam to use for subsequent communications on the SCell. Based on the report, the base station may modify its transmission configuration for the SCell and communicate with the UE via the selected beam.

Abstract: A master node associated with a primary or master network may facilitate user equipment (UE) random access channel (RACH) procedures to secondary networks for dual connectivity. A master node may identify a connected UE is to perform a RACH procedure for connection with a secondary network (e.g., to the same network as the primary network via a secondary node). The master node may then identify a transmit beam for the secondary node to use for reference signal repetitions based on a beam report received from the UE. The master node may transmit an indication of the repetition, which may include a number of repetitions and/or a transmit beam to be used for the reference signals of the RACH procedure. The UE may perform a receive beam sweep procedure while the secondary node transmits the reference signal repetitions on the transmit beam to identify a preferred receive beam.
