摘要： The present disclosure relates to methods and arrangements for determining a next interlace to be applied during a next transmission interval for a transmission in an unlicensed spectrum. A method for determining a next interlace having a next structure to be applied during a next transmission interval is disclosed. The next structure is to be applied for a transmission over a wireless interface in a wireless communications network operating in an unlicensed spectrum, wherein a first interlace is applied during transmission in a first transmission interval and wherein the first interlace has a first interlace structure formed by a plurality of physical resource blocks, PRBs, that are arranged with a given subcarrier spacing in one of a set of interlaces. The method comprises defining (S21) a frequency shift based on the number of PRBs per interlace and a maximum allowed power for a single interlace and determining (S22) the next interlace structure by shifting the first interlace structure by the defined frequency shift. A corresponding reception method, arrangements for performing the methods and computer program products are also disclosed.

摘要： A wireless device is configured with or allocated two or more control resource sets for receiving downlink control information from a base station or cell. The two or more control resource sets correspond to two or more possible states of a time slot used for downlink transmission. The wireless device determines the state of a time slot and selects one or the two or more control channel resource sets to monitor for DCI depending on the state of the time slot. In one exemplary embodiment, the time slot has two possible states and the state of the time slot is determined by the presence or absence of an SS block.

摘要： Systems and methods relating to Discovery Signal Measurement Timing Configuration (DMTC) are disclosed. In some embodiments, a method of operation of a radio access node in a cellular communications network comprises sending, to a wireless device, a DMTC for one of a group consisting of: (a) a Secondary Cell (SCell) configured for the wireless device such that the DMTC is a specific DMTC for the SCell and (b) a frequency on which one or more asynchronous cells are operating, an asynchronous cell being a cell that is unsynchronized with a Primary Cell (PCell) of the wireless device. A DMTC configuration that is specific to a SCell provides improved measurement performance on the SCell because, e.g., the DMTC configuration can be specifically tailored to that SCell. A DMTC configuration for a frequency on which one or more asynchronous cells are operating provides improved measurement performance on that carrier.

摘要： A network node of a terrestrial cellular system provides telecommunications service to a user equipment (UE) in an airborne aircraft. Navigation information transmitted from the aircraft is periodically acquired, including aircraft identity, position, altitude, and a time of determining aircraft position. A link is maintained between the network node and the UE by transmitting beam steered, Doppler shift compensated downlink signals, and by performing beam steered reception of uplink signals. Beam steering is directed toward the aircraft based on the navigation information. Doppler shift compensation is adapted to compensate for a Doppler shift such that the UE experiences a nominal carrier frequency when receiving transmissions from the antenna nodes. Handover from a first to a second coverage area includes using a same cell identifier and a same frequency allocation in the second coverage area as are used in the first.

摘要： The present disclosure relates to a method performed in a UE radio device 4 Connected to a communication network 1 comprising a core network (CN) 5 and a Radio Access Network (RAN) 2 , e.g. eNB, where there is a communication bearer between the radio device and the CN via the RAN comprising a radio bearer 11 between the radio device and a RAN node 3 of the RAN. The purpose of the method is to adapt a Quality of Service (QoS) of the communication bearer, and in particular of the radio bearer, depending on whether critical data or non-critical data is being transmitted. The UE sends to the eNB an indication of which QoS shall be applied to the radio 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 by the UE radio device 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.
