Abstract: There is provided a method in a radio communication network providing a service for a plurality of devices, the method comprising: determining a service outage probability for a device that is going to move to a sub-area of a coverage area of the network, the service outage probability associated with said sub-area; in response to determining that the service outage probability exceeds a threshold, requesting a measurement device to move to said sub-area and to perform one or more radio frequency measurements; determining whether the service outage probability exceeds another threshold based at least on the requested one or more radio frequency measurements; and triggering at least one action if the service outage probability exceeds said another threshold.

Abstract: A method, apparatus and computer program products are provided for facilitating coordinated content delivery in multicast/broadcast networks. One example method includes receiving content from a service provider during a content service period, identifying a content service break period, the content service break period characterized by a break in transmission of content from the service provider intended for user devices, fetching localized content, and causing delivery of the localized content during the content service break period, the delivery of the localized content being performed via Xcast to determine a most radio resource efficient delivery mechanism.

Abstract: To efficiently use uplink resources while fulfilling latency requirements of low latency services, an access node, a resource pool allocated for contention based transmissions of low latency communication services may be used for transmissions of data services, since an access node providing the resource pool, is caused to send, in response to not being able to decode terminal device identification information from a sensed scheduling request, a stop instruction to terminal devices that are using the resource pool to transmissions of the data services. Further, the terminal device that sent the scheduling request is caused to use the resource pool for transmissions of the low latency service if a response is not received within predetermined time.

Abstract: Various communication systems may benefit from reliable random access. For example, fifth generation (5G) wireless communication systems may benefit from a coordinated reliable random access technique based on common random access channel resources for a quality of service aware multi-connectivity link. A method can include preparing a random access message at a user equipment. The method can also include transmitting the random access message from the user equipment on a shared resource. The shared resource can include a resource, such as a random access channel, known by a plurality of access nodes or shared by a plurality of access nodes.

Abstract: A method is provided including configuring, by a network node, a set of resources to be used by at least one user equipment for transmitting a first type of uplink data; receiving from the at least one user equipment information that indicates that at least one resource in the set of resources comprises a second type of uplink data different than the first type of uplink data; and decoding data received on the at least one resource based on the information.

Abstract: Various communication systems may benefit from techniques and systems for resource allocation. For example, communication systems of the third generation partnership project may benefit from device to device discovery resource allocation methods and systems. A method can include determining that downlink data transmission may cause conflict between uplink control channel transmission and device to device discovery signal transmissions or that uplink shared channel transmissions may conflict with device to device discovery signal transmissions; and requesting a user equipment to report device to device discovery needs based on the determining.

Abstract: Improved systems and techniques for communication in an environment in which muting of resources is used to avoid interference between cells. If a cell, represented by a macro eNB for example, is muting resources, those resources can be made available, under appropriate conditions, to user devices, such as UEs, engaging in device to device communication. Allocation of muted resources to D2D UEs can be based on meeting of conditions, such as that the D2D UEs be outside of a specified proximity to a cell, such as a small cell, using the resources, or that the D2D UEs transmit at less than a specified power. The UEs may take measurements to determine if the conditions are met and report the measurements to their base stations, which then determine whether to allocate the muted resources and configure the UEs with resource allocation information.

Abstract: In one aspect, there is a method. The method may include receiving an image of a vehicle from a sensor. The image may include identifying information of the vehicle. The method may further include generating an identifier for the vehicle based on the identifying information. The method may also include sending a message to the vehicle. The message may include the generated identifier in order to identify a destination address of the message. The above-noted aspects and features may be implemented in systems, apparatuses, methods, and/or computer-readable media depending on the desired configuration.

Abstract: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.
