  • Publication number: 20190230610
    Abstract: A method in a user equipment for updating a timing of a first cell is provided. The timing is the arrival time of a signal sent from a base station in the first cell relative to a clock in the user equipment in a wireless communication network. The user equipment measures a timing offset for the first cell and respective one or more second cells. When a quality of the timing offset measurement of the first cell is below a first threshold, the user equipment computes a timing offset estimate for the first cell based on the measured timing offset for the respective one or more second cells. The user equipment then updates the timing of the first cell based on the computed timing offset estimate.

  • Publication number: 20190124517
    Abstract: A network node for wireless access is operating in a cellular network for an unlicensed frequency band and arranged for serving wireless devices in the unlicensed frequency band. The serving of the wireless devices in the unlicensed band relies on making a clear channel assessment in the unlicensed band for ascertaining that the unlicensed band is currently not occupied by other transmissions and when not occupied commencing transmission. Upon commencing the transmission, the network node is arranged to attempt scheduling a paging message together with a message providing a discovery signal and determine whether the transmission of the discovery signal and the paging message use the same subframe scrambling code, and if they do, transmit the paging message and the discovery signal in the same subframe. A method and computer program for the network node are also disclosed.

  • Publication number: 20190053082
    Abstract: In one aspect, a wireless device monitors radio link quality for a link between the wireless device and a wireless transmitter that is configured to transmit a discovery signal at spaced, periodic, intervals and that is further configured to intermittently transmit subframes carrying user data, such that the wireless device is unable to predict which subframes will carry user data before attempting to detect the subframes. The wireless device collects, for each of the spaced, periodic, intervals, discovery-signal signal quality metrics corresponding to the discovery signal. The wireless device also collects, for each detected subframe carrying user data, detected-subframe signal quality metrics corresponding to the detected subframe.

  • Publication number: 20180332522
    Abstract: 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.

  • Patent number: 10111152
    Abstract: A network node in a cellular telecommunications system hands over responsibility for serving a wireless communication equipment from a serving cell to a target cell, wherein the wireless communication equipment is situated in a first aircraft that is in-flight. An aircraft position, an aircraft velocity, and an aircraft direction are determined. For each candidate cell of a number of candidate cells, a level of beam distortion that would result from a beam directed from the candidate cell to the first aircraft is predicted. The target cell is selected from the candidate cells by identifying which of the candidate cells has a least amount of predicted beam distortion. The target cell is then signaled to prepare for a handover of responsibility for serving the wireless communication equipment.

  • Publication number: 20180295654
    Abstract: A network node and a method therein for configuring a first communications device to monitor reception of an information signal in monitoring time periods of different time durations. One monitoring time period being relatively shorter than another, longer monitoring time period. The information signal is repeatedly transmitted by a Radio Network Node (RNN) with a first periodicity during the longer monitoring time period and with a second periodicity during the shorter monitoring time period, the first periodicity being longer than the second periodicity. The network node determines that the first communications device is to be configured for monitoring reception of the information signal within one or more shorter monitoring time periods. Further, the network node configures the first communications device with a Discontinuous Reception cycle indicating a monitoring time point falling within the one or more shorter monitoring time periods.
