Abstract: A method and a User Equipment (UE) for beam operations are provided. The method includes monitoring at least one of a plurality of Control Resource Sets (CORESETs) configured for the UE within an active Bandwidth Part (BWP) of a serving cell in a time slot; and applying a first Quasi Co-Location (QCL) assumption of a first CORESET of a set of one or more of the monitored at least one of the plurality of CORESETs to receive a Downlink (DL) Reference Signal (RS), wherein the first CORESET is associated with a monitored search space configured with a lowest CORESET Identity (ID) among the set of one or more of the monitored at least one of the plurality of CORESETs.

Abstract: A method performed by a wireless communication device includes determining whether to transmit a first Sidelink Synchronization Signal (SLSS) according to a priority parameter when an occasion of the first SLSS collides with a Physical Sidelink Feedback Channel (PSFCH) that carries Sidelink Feedback Control Information (SFCI). The priority parameter is associated with a Physical Sidelink Shared Channel (PSSCH) that corresponds to the PSFCH.

Abstract: Some of the present implementations provide a method for a user equipment (UE) for receiving a power saving signal. The method receives, from a base station, a power saving signal comprising a minimum applicable K0 (K0min) that indicates a minimum scheduling offset restriction between a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH). The method determines an application delay based on a predefined value. The method then applies the minimum scheduling offset restriction after the application delay.

Abstract: A method for PDCCH monitoring performed by a UE is provided. The method includes performing the PDCCH monitoring in a first group associated with at least one first PDCCH monitoring configuration; receiving, from a base station, DCI comprising an indicator; performing the PDCCH monitoring in a second group associated with at least one second PDCCH monitoring configuration; and stopping the PDCCH monitoring in the first group after receiving the indicator.

Abstract: An air cleaning device using water as a filter comprises a water tank, a water pump, a pressure equalizer and air-inhale tubes. The water tank includes an accommodation space for containing water, air inlets and air outlets. A cover hoods the water tank and has a water storage tank and air inlets. The water pump is disposed inside the water tank and connected with the pressure equalizer. Jet pipes of the pressure equalizer respectively interconnect with the air inlets through the air-inhale tubes. The water pump sucks the water in the accommodation space. Through the air-inhale tubes, the jet pipes inhale air in a jet fashion from exterior of the air inlets disposed in multiple directions. The air cleaning device can filter out the impurities in the air and fast clean the air of a large space. The present invention uses water as the filter and favors environmental protection.

Abstract: A water pressure-type aeration device including a water pump that generates powerful water pressure, with the water pumped through a water distribution head and a number of water distribution tubes which are placed throughout the water of a pond (or tank). The ends of the water distribution tubes are installed to cavitation housings, with the each of the cavitation housings connected at an angle of 90 degrees to the fresh air supply tubes which are directly conjoined to air filter and delivery devices floating on the surface of the water. When water is conveyed under pressure to the cavitation housings at the ends of the water distribution tubes, rear pressure constrictive openings in conjunction with a spray guide elements inside the housings generate powerful water pressure and the resulting friction across the tubular openings of fresh air supply tubes draw air in that is mixed with water in the cavitation housings and discharged from spray nozzles, thereby replenishing oxygen in the water.
