Abstract: In New Radio, NR, when a SR PUCCH resource to which a triggered SR is mapped overlaps with a PUCCH carrying UCI, such as HARQ-ACK and/or CSI, an indication of the corresponding schedulingRequestID, which determines the logical channel ID with new data, is directly encoded in the UCI. That is, rather than directly transmit the relevant SR PUCCH resource(s), which indirectly identifies the SR ID, an indication of the SR ID is directly transmitted on the PUCCH transmission. The encoding of an indication of SR ID may comprise adding bits to UCI to be transmitted, for PUCCH formats 2, 3, or 4. For PUCCH format 0, encoding the indication of SR ID comprises adding an initial cyclic offset indicating the triggered SR.

Abstract: A device for actuating outlet valves that are acted on via a valve bridge of a valve-controlled internal combustion engine for motor vehicles includes a first piston-cylinder unit in the force flow between a cam of a driving camshaft and one of the outlet valves. When one of the outlet valves opens under the action of exhaust-gas counterpressure, play compensation in the valve drive can be produced in order to hold the one of the outlet valves open by the first piston-cylinder unit. A second, coaxial piston-cylinder unit interacts with a positionally fixed counter bracket and controls a discharge duct out of the pressure chambers of the two piston-cylinder units. The piston of the first piston-cylinder unit is preloaded in a readjustment direction by a spring. To reliably obtain a lack of play in the valve drive in particular during engine braking operation, the readjustment spring acts, without being supported in the valve bridge, on the pistons of both piston-cylinder units.
