Methods, systems, and devices for wireless communications are described. The described techniques provide for dynamic updates to beam failure detection (BFD) reference signals (RSs) and path loss RS using medium access control-control element (MAC-CE) or downlink control information (DCI). For example, the quasi co-location (QCL) of periodic CSI-RS may be dynamically updated by the MAC-CE or DCI when the periodic CSI-RS is for BFD RS. Also, a semi-persistent CSI-RS or aperiodic CSI-RS may act as a BFD RS. An enhanced update procedure may be used to update the path loss RS dynamically using MAC-CE or DCI. In some cases, the path loss RS parameters updated via MAC-CE or DCI may overwrite the previously RRC configured path loss RS parameters. In another example, if the path loss RS is not configured, then the path loss RS by default may be the spatial relation reference signal of the corresponding uplink beam.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify, during a connected mode or an idle mode of a user equipment, a set of synchronization signal block communications, wherein the set of synchronization signal block communications includes two or more synchronization signal block communications; and transmit, to a user equipment, the set of synchronization signal block communications using spatial multiplexing, wherein the set of synchronization signal block communications are each transmitted concurrently using different spatial resources associated with beam sweeping transmission. Numerous other aspects are provided.

Techniques for dynamic adjustment of the frequency offset and timing advance for a UE in a non-terrestrial (NTN) are described. Details of Medium Access Control (MAC) Control Element (CE) and Downlink Control Information (DCI) based methods for indicating the timing and/or frequency adjustment commands either separately or jointly in the presence of delay and/or Doppler variations in NTN are provided. A terminal, also known as a user equipment (UE), can use DCI or MAC signaling to update the timing and frequency adjustment in presence of delay and Doppler variations in NTN. Further, a configurable MAC-CE design is provided for indicating commands related to timing and/or frequency adjustment. Procedures are also provided to report, during a random access procedure, the timing and frequency adjustment applied in preamble transmission.

A terminal receives a master information block and a synchronization signal block from a radio base station, and acquires an offset between the synchronization signal block and a control resource set by using a parameter for quasi co-location derivation included in the master information block. The terminal assumes quasi co-location associated with the synchronization signal block based on the acquired offset.

A user equipment may be configured to perform predictive methods for SSB beam measurements. In some aspects, the user equipment may receive, from at least a base station, a first set of one or more synchronization signal block beam identifiers corresponding to a first set of one or more SSB beams belonging to a SSB burst, and receive, from at least the base station, the SSB burst including the first set of one or more SSB beams.

Implementations disclosed describe techniques and systems to facilitate efficient operations of wireless networks organized in a topology of communicating nodes. Techniques include cascade synchronization of various nodes of the network by generating and maintaining a common time using times associated with ordered communications between nodes. The common time maintained by the network allows performance of synchronous action for precise industrial, medical, and testing applications. The described techniques and systems further include management of communication windows between different nodes in a way that facilitates fast and efficient propagation of data collected by the network from multiple source nodes to one or more destination nodes. The techniques further include efficient assignment and flexible management of communication frequencies (channels) to various nodes of the network to reduce interference and noise by assigning different communication frequencies to the nodes that utilize concurrent communications windows.
