Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a first downlink grant (e.g., a PDCCH transmission) for a first data transmission (e.g., a PDSCH transmission) over a first component carrier; the first data transmission over a second component carrier; and a second downlink grant (e.g., another PDCCH transmission) for a second data transmission (e.g., another PDSCH transmission) over the second component carrier. A user equipment (UE) receives the first data transmission over a first beam and may use the first beam for receiving the second data transmission. Additionally or alternatively, the UE may receive a configuration message indicating a set of TCI states for downlink data transmissions to the UE; identify one or more reference signals monitor for beam failure detection (BFD), identify one or more BFD beams, monitor the identified one or more reference signals; and selectively trigger a beam failure reporting procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a first beam measurement report from a second wireless device, the first beam measurement report indicating a first set of beam measurements for a wireless channel between the first wireless device and the second wireless device. The first wireless device may transmit to the second wireless device a cluster validity metric for at least one beam in the first beam measurement report. The first wireless device may receive from the second wireless device, in response to transmitting the cluster validity metric, a second beam measurement report indicating a second set of beam measurements for the wireless channel. The first wireless device may select a beam for transmitting to the second wireless device based at least in part on the first and second beam measurement reports.

Abstract: Methods, systems, and devices for wireless communications are described that provide beam determination in beamformed wireless communications. A base station may transmit multiple repetitions of control information for a subsequent scheduled transmission. A user equipment (UE) may receive one of the multiple repetitions, determine the control information, and adjust beamforming parameters for the scheduled transmission. The UE may have a scheduling threshold that corresponds to a time needed for the UE to adjust beamforming parameters for the scheduled transmission, and the UE may identify the beamforming parameters for the scheduled transmission from any one of the multiple repetitions of control information, which may be transmitted using different downlink transmission beams, before or after the scheduling threshold, or combinations thereof.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit to a base station an indication of a UE capability associated with a beam change at the UE. The UE may receive, from the base station during a scheduling slot, a control signal including a transmission configuration indicator (TCI) and a grant for a transport block over a first slot aggregation including a set of slots. In some cases, each slot of the first slot aggregation is offset from the scheduling slot according to a scheduling constraint based on the indicated UE capability. The UE may transmit or receive the transport block over the first slot aggregation using a UE beam based on the TCI.

Abstract: In a first configuration, the apparatus may be a base station. The base station adjusts a periodicity for performing a beam sweep, sends information indicating the adjusted periodicity for performing a beam sweep, and performs the beam sweep at the adjusted periodicity. In a second configuration, the apparatus may be a UE. The UE receives information indicating a periodicity for performing a beam sweep from a base station, adjusts the periodicity for performing the beam sweep, and performs the beam sweep at the adjusted periodicity. For both configurations, the beam sweep is a plurality of transmissions of a beam in a plurality of different transmit spatial directions by one of the base station or the UE and a plurality of scans of the beam transmissions in a plurality of different scan spatial directions by an other of the one of the base station or the UE.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.
