The first apparatus transmits, to the second apparatus, a second phase continuity reset indication after determining to change the transmission beam for the periodic sensing signal from the second beam back to the first beam.

The UE monitors for or receives the PDCCH/PDSCH based on at least one of a search space (SS) set configuration enhancement for the PDCCH, a demodulation reference signal (DM-RS) resource configuration enhancement for the PDCCH or the PDSCH, or a scrambling identifier set enhancement for payload bits of the PDCCH or the PDSCH, which support the spatial division multiplexing (SDM) with another PDCCH/PDSCH that are broadcast or group-cast from the same base station and have the quasi co-location relationship with a different SSB block or a different CSI-RS beam.

Abstract: Methods, systems, and devices for wireless communications are described. An aircraft may relay, to a terrestrial base station, an emergency message received from a user equipment (UE) located outside of a coverage area of the terrestrial base station. For example, the UE may be unable to transmit the emergency message to the terrestrial base station based on being located outside of the coverage area. Instead, the UE may transmit the emergency message to an aircraft within its communication range, and the aircraft may transmit the emergency message to the terrestrial base station. To support such emergency message communication, a non-terrestrial network (NTN) node may transmit aircraft information for the aircraft to the UE that enables the UE to transmit the emergency message to the aircraft. The NTN node may receive the aircraft information from the aircraft or the terrestrial base station.

Abstract: A propellant applied to a thruster, especially a pulsed plasma thruster, has a composition including a polymer and a metal powder material mixed with the polymer. A method of manufacturing the propellant includes dissolving polymer particles in a solvent for generating a solution, adding a powdered metal material to the solution for obtaining a mixture, and drying the mixture for removing the solvent from the mixture. Accordingly, a dried mixture is acquired and defined as a metal composite polymer which serves as the composition of the propellant. Accordingly, the use of the propellant allows a decrease in the voltage involved in a punching process and an efficient reduction in the energy consumption and assists the thruster in increasing the propulsive efficiency.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.
