Abstract:
There is provided a method, including: receiving, by a target base station, information that a handover of a plurality of user equipment currently connected to a source cell is needed to a target cell; causing a device-to-device, D2D, cluster generation, wherein each generated D2D cluster is controlled by a predetermined user equipment connected to the target cell and acting as a D2D cluster head; determining D2D cluster-specific radio resource commitment information for each generated D2D cluster; indicating corresponding D2D cluster-specific radio resource commitment information to each D2D cluster head; and receiving a handover request from at least one D2D cluster head, wherein the handover request is for handing at least one member of the corresponding D2D cluster over to the target cell.
Abstract:
A network apparatus, such as a road side unit, measures signalling transmitted from vehicle devices, to obtain the status of road traffic in the proximity of the road side unit. If a pre-defined triggering event is detected in the status of the road traffic in the proximity of the road side unit, the road side unit transmits to a serving network node, a status report in order to report the obtained road traffic status to the serving network node. The road side unit receives from the serving network node, control signalling indicating at least one road side unit operation mode selected for communication, and sets the operation mode of the road side unit to correspond to the at least one selected road side unit operation mode for the communication.
Abstract:
It is provided a method, including monitoring if a capability information on a capability of a first network for semi-persistent scheduling of a resource for a terminal is received; determining, if the capability information is received, a second allocation scheme of the resource for the terminal such that an allocation of the resource according to the second allocation scheme is not in conflict with an allocation of the resource according to a first allocation scheme derived from the received capability information; controlling an allocation device of a second network to allocate the resource to the terminal according to the second allocation scheme.
Abstract:
An aspect is an apparatus comprising: at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: detect absence of a cell providing a given service; on the basis of the detection, carry out configuration to operate as an ad-hoc cell providing the given service, and in connection with the configuration, cause establishment of a backhaul connection for the given service.
Abstract:
An example implementation relates to an apparatus including: at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: compare the need for frequency resources with currently allocated frequency resources, and if the need for frequency resources is less than the currently allocated frequency resources, inform at least one other node about at least one releasable frequency resource, the at least one releasable frequency resource comprising at least one frequency resource exceeding the need for frequency resources, and at least one rule associated with the at least one releasable frequency resource the at least one rule defining reallocation principles.
Abstract:
Systems, methods, apparatuses, and computer program products for a random access channel (RACH) procedure based proximity-based service channel allocation are provided. One method includes controlling receiving, by a network node, a request for proximity-based service on a random access channel, the request being for at least one resource, and determining whether the requested at least one resource is allocable within a random access contention window. When the at least one resource is allocable, the method may include preparing a transmission of allocation information on a common control channel. When the at least one resource is not allocable, the method may include preparing a response for the request on the random access response channel, and preparing a transmission of allocation information either on common control channel or dedicated control channel
Abstract:
Example implementations are described related to a dynamic resource allocation scheme for use in allocating frequency resources from a frequency band shared by a plurality of small area cell base stations located in a service area of a large area cell base station. The large area cell base station may control the dynamic resource allocation from the shared frequency band.

The solution may include determining the possibility of releasing at least part of the dedicated channel resources used for direct device-to-device communication with a group of user terminals; selecting, from the group, at least one user terminal to which the at least part of the channel resources are transferred; and controlling the transmission of a transfer message to the group of user terminals, the message indicating the at least one user terminal the at least part of the dedicated channel resources are transferred to.
Abstract:
Apparatuses and methods in a communication system are provided. The solution includes communicating with a communication system as authentic and authorized user equipment; storing information on another user equipment and communicating with the communication system to authorize the access of another user equipment to the communication system.
Abstract:
Initial Setting and Configuration of E-UTRAN for Energy-Efficient IOPS Certain embodiments of the invention generally relate to initial setting and configuration of E-UTRAN for energy-efficient isolated E-UTRAN operation for public safety. A method may include determining an initial configuration mode of a network element for setting up a self-controlled radio access network. The method may also include determining an initial downlink transmission power of the network element coupled with the determined initial configuration mode. The method may further include detecting a need of changing downlink transmission power of the network element based on at least one of traffic demands and conditions of the self-controlled radio access network. The method may also include determining a new downlink transmission power. The method may further include indicating the change of at least one of the downlink transmission power and the initial configuration mode to at least one user equipment.
