1. A method performed by a wireless device in a wireless communication network for reducing paging occasion monitoring power consumption, the method comprising:
receiving a paging indication from a base station;
transitioning to a sleep mode in response to receiving the paging indication because the wireless device is aware, prior to the wireless device decoding the paging indication, that any paging message corresponding to the paging indication is to be transmitted by the base station at least with a guaranteed minimum length of delay after the base station transmits the paging indication;
determining, while in the sleep mode, whether the wireless device is to receive a paging message corresponding to the paging indication; and
staying in the sleep mode or transitioning into a deeper sleep mode in response to a determination that the wireless device does not need to receive the paging message corresponding to the paging indication.
