The disclosure relates to a mobile device, in particular a vehicle, or an application server, wherein the mobile device or the application server comprise: a processor, configured to: receive a notification from a network entity, in particular a base station, wherein the notification comprises information about available Quality of Service, QoS, and transmit a confirmation message to the network entity informing the network entity about an acceptance of the notified QoS. The disclosure further relates to a network entity, comprising: a network entity controller, configured to: transmit a notification to a mobile device, in particular a vehicle, or an application server, wherein the notification comprises information about available Quality of Service, QoS, and receive a confirmation message from the mobile device or the application server informing about an acceptance of the notified QoS.

Techniques for quality of service negotiation

The present disclosure relates to a user equipment that includes a communication interface configured to perform communication with one or more nearby UEs using one or more of a plurality of resources in a cellular communication network, and processing circuitry configured to operate the UE in a first mode and in a second mode. The first mode is a scheduled resource allocation mode, and the second mode is an autonomous resource selection mode or an idle mode. The processing circuitry is configured to switch from the first mode to the second mode based on a first condition relating to an out of coverage event of the UE being met and a second condition related to a further parameter being met.

Devices and methods for device to device (D2D) communication

The present disclosure relates to wireless communication devices, network devices, and wireless communication methods. One example wireless communication device selects and reserves a specific resource or a specific transmission pattern for a predetermined time period. The wireless communication device sends, to at least one User Equipment (UE), a sidelink control message using a determined sidelink resource, the sidelink control message indicating the specific resource or the specific transmission pattern. The wireless communication device transmits an uplink or sidelink data message using the specific resource or the specific transmission pattern.

Communication devices and methods for providing uplink and sidelink resource reservation schemes

A base station is configured to: configure a transmission group including at least two User Equipments (UEs), and transmit a signal to at least one of UEs in the transmission group. The signal includes information about a feedback to be received from at least one of the UEs in the transmission group. The feedback includes information about the UEs in the transmission group. A UE is configured to: receive a signal from a base station, in particular a gNB. The signal includes information about a feedback to be reported to the base station from at least one of the UE or another UE in a transmission group configured by the base station. The transmission group includes at least two UEs.

Techniques for group-based feedback for groupcast transmission in communication systems

A mobile device, in particular a vehicle, or an application server, includes a processor, which is configured to receive a notification from a network entity, in particular a base station. The notification includes information about available Quality of Service, QoS. The processor is configured to transmit a confirmation message to the network entity informing the network entity about an acceptance of the notified QoS. A network entity includes a network entity controller, which is configured to transmit a notification to a mobile device, in particular a vehicle, or an application server. The notification includes information about available Quality of Service, QoS. The network entity controller is configured to receive a confirmation message from the mobile device or the application server informing about an acceptance of the notified QoS.

A radio resource controller (RRC) is provided for use in a radio cell, in particular a base station, to preserve communication in an out-of-coverage (OOC) area. The RRC includes a processor configured to: determine an egress traffic of mobile communication devices and determine an ingress traffic of mobile communication devices, in particular vehicles, from the OOC area to the area covered by the radio cell. The processor is further configured to determine a demand of radio resources for services running on the mobile communication devices entering the OOC area, and to schedule radio resources for the admitted services based on an admission and scheduling metric with respect to the egress traffic, the ingress traffic, and the demand of radio resources.

Radio resource controller preserving communication in an out-of-coverage area

A method for providing, by a service provider, a service in a vehicular network including a control channel for exchanging management frames among communicating entities and a plurality of service channels for exchanging application-specific information among the communicating entities, includes receiving, from a service user, a request for a requested service. The method further includes performing channel load estimation on one or more of the plurality of service channels, and performing, based on the results of the channel load estimation and a priority of the requested service, scheduling the requested service to one of the plurality of service channels.

Method for multi-channel operation in a vehicular network and vehicular network

A method for managing communication between a plurality of moving objects, wherein one or more communication channels are used for the communication, wherein each moving object is operable to adjust a transmit power level for transmitting information via the one or more communication channels, and wherein each moving object is operable to adjust a transmit rate for sending information via the one or more communication channels, includes performing, for each of the plurality of moving objects: a) adjusting the transmit power level of each moving object independently of other moving objects such that a target cooperative awareness ratio is achieved, and b) adapting the transmit rate at each moving object independently such that a channel load of a respective communication channel is within a predefined load interval.

Managing communication between a plurality of moving objects through control of transmit power and/or transmit rate

A method for multi-channel operation in a vehicular network, the vehicular network including a plurality of communicating entities being designated as either a service provider or as a service user, a control channel for exchanging management frames among the communicating entities, and at least two different service channels for application-specific information exchange among the communicating entities, includes performing, by the communication entities, channel load estimation through a combination of physical channel measurements and an analysis of the transmitted service announcement messages (SAM) generated by service providers; and performing, by the communication entities based on the results of the channel load estimation together with existing services on the service channels and user and/or application preference configurations, dynamic service channel switching to either provide or consume a service.

A method for controlling messages between communicating entities (CE) having computing devices, each CE sending messages to other neighboring CE with a entity-dependent message rate (CEMR), and with an entity-dependent transmission power, the messages being transmitted via one or more channels having a maximum channel capacity, and the CEMR defining a rate interval between a minimum and maximum rate, includes determining the CEMR within the rate interval by: (a) using a utility function for each CE; b) assigning an initial price for each CE; (c) adjusting the CEMR of each CE accounting for received prices of other CE; (d) computing a new price for each CE based on difference between initial price and available channel load for respective CEs; and (e) checking a termination condition for the difference and if unfulfilled, use the new price as initial price and repeat (c)-(e) until a termination condition is fulfilled.
