Abstract: Various communication systems may benefit from proper handling of mobility. In particular, connected mode mobility may be suitably addressed for enhanced coverage user equipment. A method can include determining to attempt access to a target cell in enhanced coverage mode. The method can also include sending, based on the determination, a report to a source cell of an intent to access the target cell in enhanced coverage mode.

Abstract: A user equipment (UE) and a network access node (eNB or CIoT-BS) each store in their local memory the UE's context. Automatically upon a designated communication between them a timer is initiated that indicates the UE context is valid. For transitioning the UE from an idle to a connected mode, there is a selection between a first and a second procedure and this selection is based on the timer and on at least one other prescribed validity criterion (for example, context validity area, radio conditions or CE level). Data is then sent or received on a radio connection that is obtained via the selected first or second procedure, where only one of the first and second procedures utilizes the stored UE context. During that procedure, in an embodiment the UE can send to the CIoT-BS an indication that it has the stored UE context.

Abstract: Systems, methods, apparatuses, and computer program products for narrow band internet of things (NB-IoT) paging optimization are provided. One method includes, when extended discontinuous reception (eDRX) is not configured for a user equipment (UE), applying a maximum repetition number of each coverage enhancement (CE) mode for paging transmission and associating a different repetition number with each paging occasion (PO). When extended discontinuous reception (eDRX) is configured for the user equipment, the method includes associating each paging occasion (PO) with a different repetition number.

Abstract: In accordance with some embodiments, an apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least receive at least one random access preamble from user equipment. The at least one memory and the computer program code can be further configured to, configure at least one backoff indicator. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least transmit the at least one backoff indicator and at least one backoff configuration indicator to the user equipment. The at least one backoff configuration indicator is used to indicate how the at least one backoff indicator is applied.

Abstract: Various communication systems may benefit from time discontinuous transmission. For example, narrow band Internet of things (NB-IoT) may benefit from having transmissions with sufficient time diversity to avoid unnecessary repetition. A method can include configuring a control channel and data channel partitioning pattern within a configured time period. The method can additionally include communicating with at least one user equipment based on the control channel and data channel partitioning pattern.
