Abstract: In the present invention, service data units (SDUs) are delivered from a first layer to a second layer out-of-order irrespective of sequence numbers (SNs) of the SDUs. The second layer deciphers the SDUs in the order of reception from the first layer irrespective of the SNs. The second layer may reorders the deciphered SDUs in the order of the SNs, and delivers them to an upper layer in sequence.

Abstract: A method and apparatus for random access fallback procedure related to MT EDT in a wireless communication system is provided. A wireless device receives, from the network, a paging including a dedicated random access (RA) resource corresponding to a first coverage enhancement (CE) level. A wireless device initiates a first RA attempt using the dedicated RA resource. A wireless device increases a CE level of the wireless device to a second CE level based on failure of the first RA attempt. A wireless device selects a non-dedicated RA resource corresponding the second CE level. A wireless device performs a second RA attempt using the non-dedicated RA resource.
