摘要： A network node and method therein for assisting a communication device to perform handover from a serving cell to a target cell in a communication network are disclosed. The network node is configured to obtain a first round trip time between the network node and a server and obtain a second round trip time between a target node in the target cell and the server. The network node is further configured to instruct the communication device to perform handover from the serving cell to the target cell based on at least the first round trip time and the second round trip time.

摘要： The present disclosure relates to a method performed in a radio device 4 connected to a communication network 1 comprising a core network (CN) and a Radio Access Network (RAN), where there is a communication bearer between the radio device and the CN via the RAN comprising a radio bearer between the radio device and a RAN node of the RAN, for adapting a Quality of Service (QoS) of the communication bearer. The method comprises, to the CN, sending a request for a first QoS to be associated with the communication bearer. The method also comprises exchanging data over the radio bearer in accordance with the first QoS of the communication bearer. The method also comprises, to the RAN, sending an indication that a second QoS, lower than the first QoS, should be used for the radio bearer. The method also comprises exchanging data over the radio bearer in accordance with the second QoS.

摘要： Telecommunications service is provided to mobile equipment aboard an airborne aircraft. A master coordination node (MCN) coordinates communication from groups of subordinate nodes in the network such that each group communicates a different layer of data to the mobile communication equipment aboard the aircraft. Each group of subordinate nodes transmits beam steered, Doppler shift compensated downlink signals directed at the aircraft. Coordination controls the timing of transmissions from the subordinate nodes so as to have signals received by the mobile communication equipment from the groups of subordinate nodes keep within a required temporal delay of a cyclic prefix in the received signals; the Doppler shift pre-compensation performed by each subordinate node such that the mobile communication equipment aboard the aircraft experiences a nominal carrier frequency when receiving transmissions from each of the subordinate nodes; and ensuring mutual compatibility of the signals transmitted by each of the groups of subordinate nodes.

摘要： There is provided association of a radio access technology, RAT, supported by a wireless device, WD, with a first service. The WD supports at least a first RAT, a second RAT and a third RAT. The second RAT supports a first service and a second service, the first RAT supports the first service but not the second service, and the third RAT supports at least the first service. An indicator that the second service is to be associated with the second RAT is acquired. An indicator that said third RAT is available for use is acquired. Channel measurements for at least one of the second RAT and the third RAT are acquired. The first service is associated with one of the second RAT and the third RAT based on the acquired channel measurements.

摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

摘要： A hidden node interference reduction method of an access point of a wireless communication network is disclosed, wherein the access point is adapted to serve a plurality of mobile terminals. The method comprises receiving a signal from at least two of the plurality of mobile terminals in response to transmitting the positioning signal, wherein each signal is indicative of a position of the respective mobile terminal. The method further comprises partitioning the plurality of mobile terminals into one or more groups by determining a metric for at least one pair of mobile terminals based on the indicated positions (wherein the pair of mobile terminals comprises a first mobile terminal and a second mobile terminal, and wherein the metric is associated with a distance between the first mobile terminal and the second mobile terminal of the pair of mobile terminals) and letting the first and second mobile terminals of the pair of mobile terminals belong to different groups if the metric fulfills a condition (wherein the condition is indicative of the first mobile terminal causing hidden node interference to the second mobile terminal). The method also comprises allocating a separate respective frequency resource to each group of mobile terminals. Corresponding computer program product, arrangement and access point are also disclosed.
