Abstract:
A method includes determining, for a first network, first activity information for shared usage of a first portion of a spectrum allocated to the first network with at least one second network and causing the activity information to be sent to at least one base station of said second network.
Abstract:
An apparatus including: at least one processor, and at least one memory for storing instructions to be executed by the processor, wherein the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least: receive and process a request for using a part of a spectrum of a second communication network by a first communication network on the basis of a spectrum cooperation relationship configuration, receive and process service coordination information and network coordination information related to the request for using a part of the spectrum, the service coordination information indicating measures offered by the first communication network allowing the second communication network to reduce a communication load by using a part of the first communication network as a communication relay as compensation for allowing to use a part of the spectrum of the second communication network by the first communication network, and the network coordination information indicating identification information identifying communication areas or cells of the first and second communication networks usable for the offered measures and configuration information required for using the offered measures, and conduct a processing for service coordination and network coordination for reducing the communication load in the second communication network by using a part of the first communication network as a communication relay, on the basis of the processing result of the service coordination information and the network coordination information.
Abstract:
To reduce handover latency experienced by a user using a user equipment that is served for offloaded user data traffic by a first small cell, a handover between a first macro cell deploying the first small cell and a second macro cell deploying a second small cell is triggered when information indicating that the user equipment has associated with the second small cell not deployed by the first macro cell is received.
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.
Abstract:
Apparatuses and methods for communication are provided. 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:
A method comprises determining in a base station of a first cell of a first network that there is an inactive second cell of a second, different network which is a candidate cell for a user equipment and causing an activation message to be sent to cause the activation of said inactive second cell.
Abstract:
Mobility management mechanism wherein a source base station is configured to send to a target base station the transmission rate history of a user equipment to be handed off from the source base station to the target base station.
