Abstract: Disclosed are two methods, the first method comprising receiving a plurality of data packets, producing a coded data packet by coding together at least two data packets, wherein at least one of the at least two data packets is comprised in the received plurality of data packets or in a coding buffer, transmitting the at least two data packets to a first subset of legs, transmitting the coded data packets to a second subset of legs, and determining if the at least two data packets are to be duplicated based on, at least partly, one or more of the following: a notification, a condition, or a first indication. The second disclosed method comprises receiving a data packet and an indication of a coding function and parameters used for coding two or more data packets, determining if the received data packet is a coded data packet and if it is, determine if one or more internal buffers comprise a minimum set of data packets for generating the coded data packet, using sequence numbers assigned to each data packet, and if the one or more internal buffers comprise the minimum set of data packets, retrieve the minimum set of data packets from the one or more internal buffers, and decoding the coded data packet using the minimum set of data packets and the coding function and parameters indicated by the indication received.

Abstract: A method of transmitting data from a user equipment (UE) in a radio resource control (RRC) inactive state to a network node is described. The example method includes detecting presence of data for transmitting to the network node and determining whether the user equipment (UE) allows a mode of operation using pre-allocated resources in the RRC inactive state for user data transmission. The example method further includes transmitting the data from the user equipment (UE) to the network node in response to determining that the user equipment (UE) allows the mode of operations using pre-allocated resources in the inactive radio resource control (RRC) state for user data transmission.

Abstract: A method, apparatus and computer program are disclosed that perform in a wireless network: monitoring radio network connectivity release requests received from a wireless device of a given subscriber of the wireless network; determining a radio network connectivity release request frequency based on the radio network connectivity release requests received from the wireless device; receiving a current radio network connectivity release request from the wireless device; determining whether the radio network connectivity release request frequency meets a first threshold and: if yes, taking first corrective action to mitigate network load by excessive radio network connectivity release requests.

Abstract: A user equipment (UE) has both cellular and non-cellular links. The network sends it a first indication to maintain using a first set of security keys generated from a parameter specific to a source access node after the UE hands over the cellular link to a target access node without changing a wireless termination (WT) that is connected with the UE via the non-cellular link. The network uses that key to maintain the non-cellular link with the UE after the cellular link handover. From the UE's perspective it uses that key to authenticate its non-cellular link prior to the cellular link handover, but this handover does not change the WT which communicates with the UE via the non-cellular link so the UE can, only in response to receiving a first indication associated with the handover, use that same key to maintain that non-cellular link after the handover.

Abstract: Example embodiments of the present disclosure are related to state transition of a cell. An apparatus receives a monitoring occasion configuration for control information related to a discontinuous operation pattern of a cell, the monitoring occasion configuration indicating at least one monitoring occasion that is before activation of the discontinuous operation pattern or during a time when the discontinuous operation pattern is activated. The apparatus monitors the control information from the device at the at least one monitoring occasion, the control information at least indicating a state transition of the cell between an active state and a non-active state; and based on receiving the control information from the device, and determines, from the control information, the state transition of the cell between the active state and the non-active state.
