Abstract: Apparatus and methods are provided for TxRU carrier switch. In one embodiment, the UE is configured with an anchor carrier in an anchor cell and one or more secondary carriers. In one embodiment, the TxRU carrier switch is configured as supplementary uplink (SUL)-based carrier switch with supplementary carriers or configured as a CA-based carrier switch with supplementary cells. In one embodiment, the one or more secondary carriers are supplementary carriers of the anchor cell, and wherein the anchor carrier is TDD carrier or frequency division duplex (FDD) carrier, and wherein the supplementary carrier is configured as a TDD carrier, a FDD carrier, a supplementary uplink carrier (SUL), or a supplementary downlink carrier (SDL). In another embodiment, the one or more secondary carriers are supplementary cells different from the anchor cell, and wherein the supplementary cells are configured with MAC control element (CE).

Abstract: Various solutions for providing a unified control channel framework in mobile communications are described. An apparatus receives a first-stage downlink control information (DCI) from a network node. The first-stage DCI indicates first scheduling information associated with a second-stage DCI. Then, the apparatus receives the second-stage DCI from the network node according to the first scheduling information. The second-stage DCI indicates second scheduling information associated with one or more carriers or cells or indicates non-scheduling information associated with one or more features. Also, the apparatus performs operations including either one of the following: (1) performing a PDSCH reception or a PUSCH transmission on at least one of the one or more carriers or cells according to the second scheduling information; and (2) applying the non-scheduling information in an event that the apparatus supports at least one of the one or more features.

Abstract: A ventilator system includes a first air tank, a plurality of second air tanks communicated with the first air tank, a plurality of breathing devices respectively communicated with the second air tanks, a plurality of first vacuum tanks respectively communicated with the breathing devices, and a second vacuum tank communicated with the first vacuum tanks. The first air tank has a positive pressure relative to the second air tanks. The second vacuum tank has a negative pressure relative to the first vacuum tanks.
