    Abstract: Embodiments described herein relate generally to a communication between a user equipment (UE) and an evolved Node B (eNB) that are both running in Enhanced Coverage (EC) mode. The UE and eNB may communicate in a contention-based random access procedure having an EC level that may be used to determine the number of times an RA preamble may be sent, and one or more RA response opportunity windows that may be used to receive one or more RA responses. Other embodiments may be described and/or claimed.

    Abstract: Technology described herein relates to systems, methods, and computer readable media to implement extended Discontinuous Reception (eDRX) for user equipments (UEs). A Mobility Management Entity (MME) can be aware of the starting time and length of an eDRX cycle of a UE so that the MME can send a paging message for the UE to an evolved Node B (eNB) shortly ahead of a Paging Occasion (PO). In some examples, more than one PO can be included within an eDRX cycle. An eDRX timer can be used to control the duration of waking times and, if desired, to maintain legacy compatibility. Additional examples provide a way for the MME to update calculations regarding the starting time and length of eDRX cycle of the UE such that the MME will continue to be apprised of when the UE will be reachable when the UE moves between cells.
