Abstract: A wireless device receives one or more messages. The one or more messages comprise configuration parameters of the cell. The configuration parameters indicate a first reference signal set for a first type of beam switching. The configuration parameters indicate a second reference signal set for a second type of beam switching. A beam switching type indication is transmitted. The beam switching type indication indicates one of the first type of beam switching or the second type of beam switching. A command confirming the beam switching type indication is received. One of the first reference signal set and the second reference signal set is selected as a selected reference signal set based on the command. A spatial domain transmission filter is determined based on at least one reference signal of the selected reference signal set. An uplink transport block is transmitted based on the spatial domain transmission filter.

Abstract: Apparatuses are described that provide for a mobile eye washing station. An example station includes a fluid storage cartridge that stores unused eye wash fluid and a nozzle assembly in fluid communication with the fluid storage cartridge. In operation, the nozzle assembly dispenses the unused eye wash fluid stored in the fluid storage cartridge via one or more nozzles of the nozzle assembly. The example station further includes a waste fluid collection basin that, in operation, collects eye wash fluid dispersed by the nozzle assembly. Due to contact with the fluid storage cartridge, the waste fluid collection basin compresses the fluid storage cartridge to drive fluid communication between the fluid storage cartridge and the nozzle assembly. The fluid storage cartridge is disposed vertically beneath the waste fluid collection basin.

Abstract: Methods, systems, and devices for wireless communication are described for polar coding with rate matching. A transmitter may construct input channels into a polar encoder to provide an information bit vector that does not include punctured or shortened bits. One or more transmission capacity factors may be used in identifying the information bit vector, which may be mapped to one or more of a codeword length of the polar code or a number of transmitted bits in each codeword. A number of different rate matching schemes may be available for transmissions, and may be selected based on one or more polar coding parameters. In some cases, mapping techniques may be used in two or more different rate matching schemes.
