Abstract: Methods, systems, and devices for wireless communications are described that provide 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 combined at the UE to enhance the likelihood of successful decoding of the control information. A base station may transmit an indication that combining of multiple instances of control information is supported by the base station, and may transmit the multiple instances of control information via configured downlink transmission resources. A UE may receive the indication that combining of multiple control information instances is supported, may identify two or more instances within downlink transmission resources configured for control information transmissions, and may combine signals received in each of the two or more instances to generate a combined control information signal.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently identifying spatial parameters for receiving control information in an initial coreset. In one example, a user equipment (UE) may receive a TCI state indicating reference signals quasi co-located with a control information transmission in a coreset, and the UE may also identify a quasi co-location (QCL) assumption in a random-access procedure indicating that a synchronization signal block (SSB) is quasi co-located with the control information transmission in the coreset. In this example, the UE may identify spatial parameters for monitoring the coreset for the control information transmission in accordance with the TCI state or the QCL assumption based on the timing of the indicated TCI state and the QCL assumption.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a user equipment (UE) with multiple control resource sets (CORESETs) for control channel monitoring. In some cases (e.g., based on a random access (RACH) procedure), the base station may update a CORESET with an updated downlink beam and, correspondingly, an updated active quasi-co-location (QCL) assumption for monitoring. In some cases, this updated active QCL assumption may cause the total number of active QCL assumptions to exceed a UE threshold value for monitoring. The UE may determine a priority order for monitoring the CORESETs, where the CORESET corresponding to the updated active QCL is assigned highest priority and the remaining CORESETs are prioritized based on CORESET or search space parameters, and the UE may either drop CORESETs from monitoring or modify active QCL assumptions for CORESETs based on the determined priority order.

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: Certain aspects of the present disclosure relate to timers used to control switching from SU to MU transmission modes. In some examples, a frame is generated having an indication of multiple timer values for one or more wireless devices to be used for switching from a multiple user (MU) mode to a single user (SU) mode. In other examples, when to switch from a MU mode to a SU mode is determined based on multiple timer values obtained from a frame, and one or more second frames are generated for transmission via the SU mode or the MU mode based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a channel configuration associated with a downlink channel. The user equipment may identify a repetition configuration for the downlink channel based at least in part on the channel configuration. The user equipment may monitor for the downlink channel in accordance with the repetition configuration based at least in part on identifying the repetition configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In order to support beamforming operations, communicating devices may perform beam management procedures (e.g., beam failure detection (BFD)). Some such devices may operate (e.g., at least some of the time) in a discontinuous reception (DRX) mode that includes alternating periods of activity and inactivity. Improved coordination of beam management procedures in consideration of DRX mode operation may benefit such devices. A device may identify that it is configured to operate in a DRX mode, where each DRX period includes an active duration and an inactive duration. The device may identify that it is configured to perform a BFD procedure and may monitor for beam failure in accordance with the BFD procedure during (e.g., only during) the active duration of the DRX period.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: Methods, systems, and devices are described for wireless communication at a receiving device. A receiving device may receive a first physical layer header of a first wireless local area network (WLAN) protocol data unit over a shared radio frequency spectrum band.
