Certain embodiments provide a method of updating a security. The method can include monitoring a bearer that includes first and second radio accesses according to different radio technologies between user equipment and a communications network. One or more properties of the monitored bearer can be determined. An update of a security key utilized for securing communications over at least one of the radio accesses can be triggered in response to determining that the determined properties meet at least one triggering condition capable of indicating a need for the update.

Updating security key

Systems, methods, apparatuses, and computer program products relating to packet data unit (PDU) session, for example, in 5G or new radio access technology (NR). One method may include receiving a configuration for how to handle flows to two network nodes for transmission. The method may include directing the flows of an incoming PDU session to two network nodes for the transmission.

Protocol data unit session splitting function and signaling

A method, apparatus and computer program product are provided to facilitate interworking a plurality of cellular radio access networks and wireless local area networks (WLANs). In the context of a method, a set of information is maintained for a plurality of different cellular radio access networks that defines a relative priority of selection among the cellular radio access networks. The method also includes maintaining wireless access selection information defining a relative priority of selection among one or more WLANs relative to the cellular radio access networks. The method also permits the relative priority of the WLANs to be modified without modification of the set of information. For example, the relative priority the WLANs may be modified in a manner specific to the user equipment or specific to a cell. The method may also include causing notification to be provided to user equipment of the set of information and the wireless access selection information.

Method and apparatus for facilitating interworking of cellular radio access networks and wireless local area networks

A method for operating a wireless communication system in a cell includes allocating a first plurality of pilot resources to a first frequency sub-band comprising a plurality of high power sub-carriers, allocating a second plurality of pilot resources to a second frequency sub-band comprising a plurality of low power sub-carriers, signaling a power offset between the plurality of pilot resources in the plurality of high power sub-carriers and the plurality of pilot resources in the plurality of low power sub-carriers, and transmitting the first and the second plurality of pilot resources over the first and the second frequency sub-bands.

Apparatus, method and computer program product providing common pilot channel for soft frequency reuse

Methods and apparatus, including computer program products, are provided for adaptation of WLAN selection thresholds. In one aspect there is provided a method, which may include receiving, at a user equipment, information including one or more thresholds for use when evaluating a selection of a wireless local area network access point for offloading; comparing, by the user equipment, a quality of an access provided by the wireless local area network access point selected in accordance with the one or more thresholds to another quality provided by a cellular access point; reporting, by the user equipment, a result of the comparing; and receiving, by the user equipment in response to the reporting, additional information including one or more adjusted thresholds for use when evaluating wireless local area network access point selection. Related systems, articles of manufacture, and the like are also disclosed.

Adaptive threshold handling for triggering WLAN offloading

An apparatus includes at least one data processor and at least one memory storing computer program code. The at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to detect in a wireless communication network an excess capacity condition and to increase, from a currently subscribed-to value, to a higher value an aggregated higher bit rate for a mobile node operating in the wireless communication network.

System and method to exploit offload capability in a wireless communications network

A method includes determining that a full PDCP status report does not fit into a single PDCP Control PDU, generating a partial PDCP status report that fits into the single PDCP Control PDU, and sending the single PDCP Control PDU containing the partial PDCP status report. Another method includes receiving a PDCP Control PDU where the maximum size thereof is limited, and determining that the received PDCP Control PDU contains a partial PDCP status report instead of a complete PDCP status report. Apparatus, program products, programs, UEs, base stations, and a communication system are also disclosed.

Enhancement of PDCP status report

Systems, methods, apparatuses, and computer program products for multipath interfaces are provided. One method includes establishing, by a user equipment, multiple network interfaces for multipath transmissions, wherein the multiple interfaces comprise a first radio interface and a second radio interface. The method also includes receiving a request from an access-path network to keep flows of the first radio interface and the second radio interface separate.

Multipath interfaces in new scenarios

Various communication systems may benefit from identification of devices or systems using a channel. For example, certain communication systems may benefit from non-orthogonal cover code for co-channel network isolation. A method can include deciding a cover code index. The method can also include signaling the cover code index to a user equipment. The cover code index can correspond to a non-orthogonal cover code that is created in a network-specific manner.

Non-orthogonal cover codes for co-channel network isolation

Resources are allocated on a shared downlink control channel by an allocation table that is partitioned into a first, fixed length partition and into at least one second, variable length partition. The fixed length and the modulation and coding scheme MCS of the first partition is known a priori. The second variable length and the MCS of the second partition may be given in the first partition. Robustness may be varied between different second partitions of the same allocation table, or even within a single second partition to account for users at different proximity to the network node giving the allocations. Users may be identified in the first partition (e.g., a fixed number of users), and/or in the second partition (either additional allocated users or all users being allocated if the first partition does not identify users). Method, apparatus, computer program, integrated circuit and systems are detailed.

Apparatus, method and computer program product providing partitioned downlink shared control channel having fixed and variable component parts

Methods and apparatus, including computer program products, are provided for a protocol interface for a heterogeneous network. In one aspect there is provided a method. The method may include detecting, by a user equipment, a local area radio network; and establishing, at the user equipment, a first entity configured to manage a first radio resource of a local area radio network, wherein the first entity includes an interface to a second entity, at the user equipment, configured to manage a second radio resource of a cellular radio network. Related apparatus, systems, methods, and articles are also described.

Management of a protocol interface for a heterogeneous network connection

An approach is provided for receiving and transmitting data over a wireless network, while minimizing power consumption. A determination is made, as part of a discontinuous communication mechanism defining an on-period for permitting transmission of data over a network, whether a resource allocation has been made to a user equipment for communicating over the network. If the resource allocation has been made, generating a keep-awake message to instruct the user equipment to extend the on-period.

Method and apparatus for providing efficient discontinuous communication

Various communication systems may benefit from coordination in interworking. For example, certain wireless communication systems may benefit from link setup level coordination, such as coordination between a first radio access technology base station and a terminal that is setting up a link to a second radio access technology. A method may include, for example, determining an allowed link setup level for a terminal. The method may also include communicating the allowed link setup level to the terminal.

Link setup level coordination

A method includes receiving packets of a flow at a packet data convergence protocol layer; and based on at least one criterion, routing the flow to one or both of at least one cellular transport radio and a wireless local area network transport radio. Another method includes receiving at a packet data network gateway from an S 1 interface a dynamic host configuration protocol request for a station; one of creating an internet protocol configuration for the station or generating another dynamic host configuration protocol request to a dynamic host configuration protocol server to obtain the internet protocol configuration; and delivering the internet protocol configuration to the station. Apparatus for performing the methods are also disclosed, as are computer-readable program storage devices.
