    Abstract: The present disclosure relates to a method to be performed at a user equipment and to a user equipment operable in a wireless communications system supporting direct communication between user equipments. Accordingly, a sidelink configuration is stored in the user equipment, 5 specifying a plurality of destination groups, each destination group including possible destinations for sidelink data as well a logical channel priority is stored for each logical channel out of logical channels configured for the sidelink destination groups. The terminal then selects a sidelink destination group with a sidelink logical channel having sidelink data available for transmission with the 10 highest logical channel priority among the sidelink logical channels having data available for transmission, and allocates radio resources to the sidelink logical channels belonging to the selected sidelink destination group in decreasing priority order.

    Abstract: Provided are systems and methods for transmitting data over a wireless channel from a data transmitting node to a data receiving node in a communication system. The data transmitting node comprises second-layer processing circuitry for receiving at least one second-layer SDU, to be mapped onto a resource allocated for data transmission, and for generating a second-layer PDU, including the at least one second-layer SDU and at least one second-layer control element, and first-layer processing circuitry for receiving the second-layer PDU generated by the second-layer processing circuitry and for mapping the second-layer PDU onto the resource allocated for data transmission. The data receiving node comprises first-layer processing circuitry for de-mapping at least one second-layer PDU, and second layer processing circuitry for receiving and parsing the second-layer PDU demapped by the first-layer processing circuitry, the second-layer PDU including at least one second-layer SDU, and at least one second-layer control element.

    Abstract: The present disclosure relates to a method for activating a relay functionality of a ProSe capable and relay-capable user equipment within a mobile communication network. The radio base station, to which the relay UE is connected, determines whether further relays are necessary in the radio cell controlled by the radio base station. In case further relays are necessary in the radio cell, the radio base station selects a persistence check value and transmits a broadcast message in the radio cell. The broadcast message at least indicates that further relays are necessary and comprises the selected persistence check value. Upon receiving the broadcast message, the relay UE activates its relay functionality in case it determines that relay requirements for activating its relay functionality in the radio cell are fulfilled and in case a persistence check performed by the relay UE based on the received persistence check value is successful.

    Abstract: The layer processing includes at least processing on a first, a second and a third layer. At the transmitter side, the third layer receives a packet, adds its header and forwards the packet to the second layer. The second layer performs segmentation and provides segmented data to the first layer, which maps the segmented data onto physical resources. The segmentation is based on the allocated resources. Retransmissions may take place on the third layer and thus, the third layer may re-segment the packet according to the received feedback for particular segments and provide the re-segmented data to the lower layers. Alternatively, the feedback information is provided to the second layer which then performs the segmentation by taking it into account. Correspondingly, the receiver performs re-ordering and re-assembly at the third layer for which it receives also control information from the second layer.
