    Abstract: A network node assigns resources for use in wireless communication based on priority. The network node receives, from a wireless communication device, a service request message that requests connection of a communication session. The network node determines a priority level for the requested communication session. The priority level comprises a cellular layer admission priority of whether the network node can preempt cellular resources of an existing communication session in order to admit the requested communication session on the cellular layer, and a device-to-device (D2D) layer admission priority of whether the network node can preempt D2D resources of an existing communication session in order to admit the requested communication session on the D2D layer. The network node assigns resources based at least in part on the priority level. The resources are used for D2D communication or cellular communication.

    Abstract: A method in a base station for adapting prioritization of a service of a user equipment over services of other user equipments is provided. The prioritization relates to a transmission between the base station and the user equipment at a scheduling occasion. The prioritization relates to an initial value. The base station decides (302) that the user equipment is in congestion, when an instant scheduling bit rate for the transmission in relation to a bit rate related to the service is below a first threshold. When the user equipment is in congestion, the base station adapts (304) the prioritization by down prioritizing the service of the user equipment in relation to the initial value, until a timer has expired.

The first wireless device is configured to transmit data to a second wireless device over a Device-to-Device, D2D, link. The first wireless device receives a report on a control channel from the second wireless device. The report comprises a measurement of SINR on said control channel and/or a data channel transmitted by the first device. The first wireless device adjusts a transmit power for the control channel and/or the data channel based on the reported measurement of the SINR on said control channel and/or data channel transmitted by the first device. The first wireless device then adjusts a SINR target and a transmit rate based on the adjusted transmit power. The SINR target and transmit rate are to be used when transmitting on the data channel over the D2D link to the second wireless device.

    Abstract: A method in a base station for adapting link adaptation of a transmission between a user equipment and the base station is provided. The link adaptation relates to an initial value of a Block Error Rate, BLER, related to the transmission. The base station decides that the user equipment is in congestion responsive to a scheduling bit rate for the transmission in relation to a rate of data packets arriving to or being sent by the user equipment being below a first threshold. Responsive to the user equipment being in congestion, the base station adapts the link adaptation by increasing the value of the BLER of the link adaptation in relation to the initial value, until the user equipment is out of congestion or until the base station detects that any one of the user equipment and the base station tries to send high priority data.

    Abstract: Systems and methods for network-assisted device discovery for device-to-device (D2D) communications are disclosed. In one embodiment, a base station in a cellular communications network receives a D2D request from a first wireless device to establish D2D communication. In response to the D2D request, the base station selects a second wireless device for D2D communication with the first wireless device based on the D2D request and information regarding wireless devices that are available for D2D communication. The base station then transmits a D2D request acknowledgment to the first wireless device that includes information that enables the first wireless device to establish D2D communication with the second wireless device. The base station also effects transmission of a D2D reconfiguration message to the second wireless device, where the D2D reconfiguration message includes information that informs the second wireless device that the first wireless device has requested establishment of D2D communication.
