    Abstract: A wireless communication device comprises: a transceiver being configured to measure a plurality of interference powers associated with a plurality of radio resources; and a processor being configured to determine, on the basis of the plurality of interference powers, conflicting radio resources of the wireless communication device. The transceiver is further configured to transmit data identifying the conflicting radio resources of the wireless communication device to at least one other wireless communication device and to receive data identifying conflicting radio resources of the at least one other wireless communication device. The wireless communication device is configured to allocate at least one radio resource from the plurality of radio resources for communicating with the at least one other wireless communication device on the basis of the conflicting radio resources of the wireless communication device and the data identifying conflicting radio resources of the at least one other wireless communication device.

    Abstract: Methods, systems and media for context-aware estimation of student attention in online learning are described. An attention monitoring system filters or restricts the time periods in which student attention is monitored or assessed to those time periods in which student attention is important. These time periods of high attention importance may be determined by processing data from the teacher, such as audio data representing the teacher's voice and/or visual presentation data representing slides or other visual material being presented to the students. Various types of presenter data from the teacher and attendee data from the students may be used in assessing the importance of attention and each student's attention during each time period. The presenter may be provided with feedback in various forms showing student attention performance aggregated or segmented according to various criteria.

    Abstract: The disclosure relates to user equipment (UE) (700), comprising: a transceiver (701) configured to transceive radio resource control (RRC) messages between the UE (700) and a radio access network (RAN); and a radio resource controller (702) configured to activate an operation mode of the UE (700) responsive to processing a first sequence (328) of RRC messages when a non-congestion situation is indicated by the RAN, wherein the radio resource controller (702) is configured to activate the operation mode of the UE (700) responsive to processing a second sequence (525, 625) of RRC messages when a special situation, in particular a congestion situation or a power saving situation to reduce the energy consumption, is indicated by the RAN, wherein a latency for processing the second sequence (525, 625) of RRC messages is less than a latency for processing the first sequence (328) of RRC messages.

    Abstract: The disclosure relates to a transmitter communication device for a D2D communication network with a plurality of communication devices, including one or more receiver communication devices and a plurality of relay communication devices. The transmitter communication device comprises: a processor configured to select a subset of plurality of relay communication devices for relaying a communication message to the one or more receiver communication devices and to configure the subset of relay communication devices to relay the communication message using one of a plurality of relay modes, including a first relay mode or a second relay mode, wherein the first relay mode is an “amplify and forward” relay mode and wherein the second relay mode is a “decode and forward” relay mode; and a communication interface configured to transmit the communication message to the one or more receiver communication devices via the subset of relay communication devices.

    Abstract: A node comprises a location unit determines that the node requires positioning support from the anchor nodes, and a transmitter to transmit a request for positioning support from the anchor nodes. The node comprises a selection unit to select a set of the plurality of anchor nodes for providing positioning support following the transmission of the request. It also causes the transmitter to transmit an instruction to each anchor node in the set that instructs that anchor node to provide positioning support to the node via a sidelink between that respective anchor node and the node. The request for positioning support is transmitted at a time that suits the node, in dependence on its own situation and the requirements of any applications it might be running. The selection unit enables the node to make a dynamic selection of appropriate anchor nodes at the time when the node needs positioning support.
