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. A wireless device, such as a user equipment and/or a base station, may determine that an active transmit beam has changed from a first transmit beam to a second transmit beam, the second transmit beam being different from the first transmit beam. The wireless device may identify a reference signal identifier that is associated with the second transmit beam. The wireless device may update, based at least in part on the identifying, a channel state information (CSI) resource setting to include the reference signal identifier, wherein the CSI resource setting is associated with the active transmit beam.

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: Methods, systems, and devices for wireless communications are described that provide for identification of beamforming parameters for a downlink transmission beam based at least in part on a set of rules that define a priority order for control transmission and data transmissions. Downlink resources may be allocated to a user equipment (UE) for a downlink transmission via a first set of downlink beamforming parameters, and the UE may also be configured to monitor a control resource set using a different set of downlink beamforming parameters within a same transmission time interval (TTI) as the downlink transmission. A UE and a base station may identify which beamforming parameters to use for the downlink transmission based on the priority order. The set of rules may define which set of downlink beamforming parameters are to be used, whether the downlink transmission is rate-matched around the control resource set, or combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit downlink control information (DCI) messages to a user equipment (UE). A DCI message may be transmitted using a particular DCI format based on the type of control information included in the DCI message. In some cases, different types of control information may be transmitted using the same DCI format. In such cases, one or more bit fields in a DCI format may be useful to a UE for one type of control information but may not be useful to a UE for another type of control information. As described herein, in order to limit the overhead associated with control information transmissions, a base station may support techniques for utilizing these bit fields in a DCI format to transmit information corresponding to the type of control information being transmitted.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine updated system information for a user equipment (UE), wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP; and transmit the updated system information to the UE using at least one of unicast signaling, multicast signaling, the configured BWP, or a particular BWP that is different from the configured BWP. Numerous other aspects are provided.

Abstract: Techniques and devices for signaling control and system information are provided. In one aspect, a base station determines a type of multiplexing and a periodicity for transmission of remaining minimum system information (RMSI). The type of multiplexing is for multiplexing the RMSI with a synchronization signal (SS) block. The base station generates an indicator that signals the type of multiplexing and the periodicity. In another aspect, a user equipment (UE) identifies the indicator and determines the type of multiplexing and the periodicity based on the indicator. The UE processes the transmission of RMSI based on the type of multiplexing and the periodicity. Other aspects and features are also claimed and described.

Abstract: Apparatuses and methods of beam switching are presented. A beam switch message (BSM) is transmitted to a second device via a first beam set. The BSM includes a command to switch from communication via the first beam set to communication via a second beam set at a switch time. It is determined whether a response message is received from the second device via the first beam set, the response message indicating that the second device received the BSM. A communication is sent to the second device via the second beam set after the switch time when the response message is unreceived.

Abstract: Wireless communications systems and methods related to performing random access procedures. A base station (BS) receives, from a user equipment (UE), a plurality of random access preambles from a plurality of beam directions, wherein each of the plurality of random access preambles is received from a different beam direction, and wherein the plurality of random access preambles are associated with multiple random access opportunities of a random access attempt. The BS sends, in response to the plurality of random access preambles, a plurality of random access response (RAR) messages in the plurality of beam directions.
