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: Certain aspects of the present disclosure relate to methods and apparatus for data transmission in synchronization slots. A method for use by a base station for data transmission in synchronization slots includes transmitting a synchronization signal (SS) burst, wherein different SS blocks of the burst are transmitted using different transmit beams and performing frequency division multiplexing (FDM) or time division multiplexing (TDM) to include one or more other types of signals that need to be multicast and are also transmitted using the different transmit beams.

Abstract: Aspects of the disclosure relate to determining a transmission configuration indication (TCI) state for receiving a multi-transmission point (TRP) communication. A receiving device receives a configuration message indicating a lowest control resource set identifier (CORESET ID) for receiving one or more downlink control information (DCI) and determines whether a state of the receiving device is within a scheduling threshold duration for decoding DCI. The receiving device then determines a TCI state for receiving data based on a TCI state associated with the lowest CORESET ID if the state of the receiving device is within the scheduling threshold duration, wherein the TCI state associated with the lowest CORESET ID indicates one or more sets of quasi co-location (QCL) parameters. The receiving device then receives the data from one or more transmission points (TRPs) based on the one or more sets of QCL parameters.

Abstract: Aspects of the present disclosure relate to techniques for multibeam PDCCH monitoring during CDRX operations. A BS may determine a configuration of one or more beams for a UE to monitor for receiving a downlink control channel from the BS, wherein the configuration is based, at least in part, on a monitoring window since the subframe in which the downlink control channel (e.g., PDCCH), indicates an initial UL, DL, or SL use data transmission for the UE. The BS may transmit, to the UE, an indication of the configuration. A UE may perform corresponding operations and may monitor one or more beams based on the received configuration.

Abstract: Methods, systems, and devices for wireless communications provide for transmission of a beam switch command to a user equipment (UE) via control channel signaling. The UE may establish a connection with a base station using a first transmission beam, receive configuration information configuring the UE to select between a first decoding hypothesis corresponding to downlink control information (DCI) including a bit field including a beam switch command and a second decoding hypothesis corresponding to the DCI not including the bit field, receive a downlink control channel transmission via the first transmission beam, decode the downlink control channel transmission in accordance with the configuration information to obtain decoded DCI, and communicate with the base station based at least in part on the decoded DCI.

Abstract: Methods, systems, and devices for wireless communications are described for transmissions of multiple instances of control information, such as remaining minimum system information (RMSI) that may be used for system access by a user equipment (UE). The multiple instances of the control information may be transmitted in a number of monitoring occasions that may be monitored by a UE, and within the monitoring occasions, the control information may be transmitted using different time locations, frequency locations, or combinations thereof. The locations may be identified based at least in part on one or more parameters associated with at least a first monitoring occasion. The one or more parameters may include an identification parameter associated with the base station or monitoring occasion, an index value associated with the monitoring occasion, a frequency parameter associated with the monitoring occasion, a control information multiplexing pattern, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described techniques provide for the identification of a sequence of beamforming parameters that are used for communications between a user equipment (UE) and a base station using a sequence of transmission beams. A UE may measure received reference signals that are transmitted in a series of downlink transmission beams from a base station, and report measurement parameters associated with the downlink transmission beams to the base station as part of a beam tracking and beam refinement procedure. The base station may provide transmission configuration indicator (TCI) states that are associated with each transmission beam. The TCI states may be recorded over a course of a periodic movement of the UE, and may be used deterministically to identify beamforming parameters for transmission and reception of a subsequent series of downlink transmission beams when the UE makes a subsequent same periodic movement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.
