1. A method, performed by a wireless device, of operating in a wireless communication network according to a duty cycle, the method comprising:
attempting to receive from the network a system access information message including information regarding the duty cycle, wherein the duty cycle is a limited ratio of an accumulated transmission duration in unlicensed spectrum as imposed on the wireless device within an observation interval; and
in response to receiving the system access information message, signaling to the network at least an uplink transmission budget specifying a remaining time the wireless device can transmit within the observation interval of its current duty cycle, in accordance with the system access information transmitted by the network.
