Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message including a first indication for updating a beam for communicating with the base station to a first beam and a second indication for configuring a set of reference signals for measuring the first beam. The UE may measure the first beam using the reference signals. The UE may communicate with the base station based on the beam measurement. The control message may include a format for jointly indicating beam updates and reference signal configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a sounding reference signal (SRS) configuration that identifies an SRS resource set that includes a plurality of SRS resources. A quantity of SRS ports configured for a first SRS resource of the plurality of SRS resources may be different relative to a quantity of SRS ports with which a second SRS resource of the plurality of SRS resources is configured. The UE may transmit a first SRS on one or more first SRS ports in the first SRS resource, and may transmit a second SRS on one or more second SRS ports in the second SRS resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) and/or a base station (BS) may identify in connection with a link failure of a primary cell, a resource in a secondary cell. The UE and/or the BS may communicate control signaling with the BS using the resource in the secondary cell as a response to the link failure of the primary cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improving the reliability of downlink transmissions from a base station to a user equipment (UE). The UE may determine one or more preferred configurations for the base station to use to transmit multiple downlink transmissions to the UE, and the UE may transmit a recommendation of the preferred configuration(s) to the base station. The base station may then determine configurations to use for the multiple downlink transmissions based on the recommendation received from the UE, and the base station may transmit the downlink transmissions to the UE using the determined configurations. Because the UE may provide the recommendation of the preferred configuration(s) to the base station, the configurations used by the base station for the multiple downlink transmissions may be selected specifically for the UE. Thus, the reliability of the downlink transmissions may improve.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for processing transmissions with multiple beams. For example, the techniques may be implemented in wireless systems in which any type of network entity (gNB or transmission reception points TRPs) send directional transmissions to user equipments (UEs) that receive the directional transmissions with receive beams.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a user equipment (UE), configuration information for both a first set of reference signals for a first beam sweeping procedure and a second set of reference signals for a second beam sweeping procedure. The UE may receive the first set of reference signals according to the configuration information, and may transmit a channel state information (CSI) report to the base station based on the received reference signals. After transmitting the CSI report, both the base station and the UE may autonomously update a transmission configuration indicator (TCI) state based on the CSI report (e.g., using a preferred transmit beam indicated in the CSI report). The base station may transmit on the preferred transmit beam, and the UE may receive on various candidate receive beams, the second set of reference signals.
