Abstract: A method may include receiving, by a user equipment from a network entity, a first downlink (DL) control signal activating semi-persistent scheduling (SPS) of a first set of downlink data transmissions, the downlink control signal indicating an applicable hybrid automatic repeat request (HARQ) feedback timing for the first set of downlink data transmissions and receiving one or more of the first set of downlink data transmissions. The user equipment may determine that an applicable HARQ feedback timing for a second set of downlink data transmission previously received with an inapplicable HARQ feedback timing has not been provided. In response to the determination, the user equipment may determine a HARQ feedback timing for the one or more of the first set of downlink data transmissions based a second DL control signal indicating an applicable HARQ feedback timing received after reception of the one or more of the first set of downlink data transmissions.

Abstract: A device for the determination of the elapsed time since the initial activation of a unit of equipment. The device consists of a first and second circuit and a switch-on element. The first circuit establishes a connection between the item of equipment and the switch-on element. The second circuit consists of at least a time-counter and a source of energy to power the time-counter. Both circuits can be activated simultaneously by the switch-on element. The first circuit can be used both as the current flow for the item of equipment and also for detecting voltage or physical energy in a component of an item of equipment. The switch-on element can be activated both mechanically and electronically. The counter-information can be presented in a display unit in both a deletable or non-deletable manner. The time-counter and the display unit are powered by their own energy source.
