There is provided amethod performed by a wireless device for managing a sleep state when a Discontinuous Reception, DRX, cycle of the wireless device is configured to be longer than a predefined value. The method comprises the following steps. Determining (S1) a future point in time indicating an upcoming, future reception occasion at which the wireless device will receive a message. Entering (S2) the sleep state. Keeping track of time (S3) during the sleep state according to a first time format by using a clock. Waking-up (S4) from the sleep state before, as monitored by the clock, the future point in time. Reading (S5) broadcasted time information according to a second time format. Obtaining System Frame Number, SFN, synchronization (S6) based on the broadcasted time information according to the second time format and received System Frame Number, SFN, information. Receiving (S7), with obtained SFN synchronization, the message at the future point in time. |
