Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via medium access control (MAC) signaling, an indication to activate one or more transmission configuration indicator (TCI) states for the UE, wherein the indication triggers at least one of a measurement of a reference signal or a transmission of a measurement report for at least one TCI state of the one or more TCI states, wherein the reference signal or the transmission of the measurement report is triggered based on an association of a TCI state with the reference signal or the measurement report. The UE may receive the reference signal based on receiving the indication to activate the one or more TCI states. The UE may transmit the measurement report based on the indication triggering the transmission of the measurement report. Numerous other aspects are provided.

Abstract: An apparatus is provided that may be configured to transmit, to a base station having multiple TRPs, a CSI report based on a set of reference signals, the set of reference signals including a first reference signal associated with a first beam direction and a second reference signal associated with a second beam direction. The apparatus may further be configured to switch, for one or more channels, to use the first beam direction with a first TRP of the multiple TRPs before an indication to switch beams is received from the base station.

Abstract: A touch sensor includes a substrate, sensing channels, and a protective layer. The sensing channels are disposed at intervals on a surface of the substrate, and any one of the sensing channels includes an electrode portion and a silver trace portion electrically connected to the electrode portion. The protective layer is disposed on the substrate and covers and encapsulates the sensing channels. After the touch sensor is subjected to a salt spray test with sodium chloride solution of a mass percentage concentration of 5% at a rate of 1 mL/H to 2 mL/H under an ambient temperature of 35° C. for 48 hours, a resistance change rate of any one of the sensing channels is less than or equal to 10%, and a resistance distribution difference between the sensing channels is less than or equal to 10%.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a medium access control control element (MAC CE) that indicates one or more transmission configuration indicator (TCI) states to be activated. The UE may receive one or more channel measurement resources (CMRs) that correspond to the one or more TCI states. The UE may transmit a channel state information (CSI) report for a first CMR of the one or more CMRs. The UE may switch to a beam that is quasi-co-located (QCLed) with a first TCI state, of the one or more TCI states, that corresponds to the first CMR, independent of receiving downlink control information (DCI) that indicates switching to the first TCI state. Numerous other aspects are described.

Abstract: A cracking process for a reaction distillation of chlorosilane slurry includes feeding a chlorosilane slurry into a phase separator, drying a solid phase, feeding a chlorosilane polymer into a plate distillation column, returning kettle materials of the plate distillation column, and dividing a material produced from a top of the column. The process adopts an ionic liquid catalyst, which is environmentally friendly and reusable. The cracking and distillation of chlorosilane polymer are carried out simultaneously to shorten the time and increase the utilization rate of raw materials, which can reduce energy consumption and save costs and facilitate industrial production. A plate column is used as a distillation column, in which the two phases of the gas and liquid are sufficiently contacted. Therefore, the transfer of mass and heat is good, the production capacity is good, and the tower is not easily blocked, thereby making it easy to clean.
