Abstract: Aspects described herein relate to configuring transmission configuration states in wireless communications. A capability of a number of transmission configuration states supported for detecting downlink beamformed signals can be indicated. One or more configurations of active transmission configuration states can be received from at least an access point and based on the capability. The one or more configurations can be processed to determine the active transmission configuration states, where at least one of the active transmission configuration states in the one or more configurations corresponds to a distinct state of a given reference signal. One or more downlink beamformed signals received from the access point can be detected based on processing the one or more configurations.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining when to transmit a beam report indicating a new beam for communicating with a base station after a current beam used for communications with the base station fails. In one example, after detecting beam failure, a user equipment (UE) may compare a quality of each candidate beam available for communicating with a base station to a beam identification threshold, and the UE may perform beam reporting based on the comparisons (e.g., refrain from transmitting a beam report if the quality of each of the candidate beams is lower than the beam identification threshold). In another example, after detecting beam failure, a UE may compare a quality of each candidate beam available for communicating with a base station to a beam detection threshold, and the UE may perform beam reporting based on the comparisons.

Abstract: Methods, systems, and devices for wireless communications are described that provide efficient beam updates in beamformed communications between a transmitting device and receiving device. The transmitting device and the receiving device may establish a connection using one or more beamformed transmission beams. The devices may periodically perform beam refinement procedures or beam training procedures and may update the transmission beams used for communications based on such procedures. Signaling to indicate the updated transmission beams may be transmitted that indicates one or more of a difference or delta from a prior beamforming parameter, a beam that was used at the receiving device for one or more measurements of a reference signal from the transmitting device, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a multi-slot downlink transmission, that a mapping from a transmission configuration information (TCI) state index to a first TCI state configuration has changed to a second TCI state configuration. The UE may select, based at least in part on the determined change, the first TCI state configuration or the second TCI state configuration to use for at least a portion of the multi-slot downlink transmission. The UE may receive the multi-slot downlink transmission during one or more slots according to the selected TCI state configuration and the TCI state index.

Abstract: In order to overcome problems that a UE may face in determining CORESETs and beams for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL relationships, UL resources, and/or spatial relationships are selected for a COT. A UE receives an indication of a set of CORESETs selected from a plurality of CORESETs or a set of QCL relationships selected from a plurality of QCL relationships. The UE determines the set of CORESETs from the plurality of CORESETs or the set of QCL relationships from the plurality of QCL relationships based on the indication received. A UE receives an indication of a set of UL resources or a set of spatial relations. The UE determines the set of UL resources or the set of spatial relations based on the indication received.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may transmit a capability message to a base station. The capability message may indicate a capability of the UE to monitor a defined number of resources across a set of component carriers (CCs) within a time period. The resources may be channel measurement resources (CMRs) or interference measurement resources (IMRs) for signal to interference plus noise measurement, reference signal (RS) resources for channel state information (CSI) measurement, beam failure detection (BFD), reference signal receive power (RSRP) measurement, link quality monitoring, or different active beams. Based on the capability of the UE, the base station may transmit a monitoring configuration to the UE that indicates a set of resources or active beams for the UE to monitor in the set of CCs. The UE may monitor the defined resources or beams received in the monitoring configuration from the base station.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), data from one or more beam pairs of a plurality of beams at least partially concurrently; determining, by the UE, one or more signal parameters for the one or more beam pairs; determining, by the UE, one or more joint quasi co-located (QCL) indicators for the one or more beam pairs and one or more non-joint QCL indicators for the one or more beam pairs; and transmitting, by the UE, a measurement report including the one or more joint QCL indicators and the one or more non-joint QCL indicators. In another aspect, a method of wireless communication includes determining a particular beam or beams for transmitting second data based on the measurement report; and transmitting the second data using the particular beam or beams. Other aspects and features are also claimed and described.

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: The apparatus determines, for a CC, an active TCI state of at least one of a CORESET of a PDCCH when the CORESET is configured on the CC or a PDSCH. In addition, the apparatus determines, based on the determined active TCI state, a default beam on the CC for transmitting at least one of a PUCCH or SRS. Further, the apparatus transmits at least one of the PUCCH or the SRS through the determined default beam on the CC.
