摘要： 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.

摘要： A carrier aggregation application method is provided of attaining time synchronization to a secondary cell for a wireless communication device usable in a cellular communication network. The method comprises, if a time reference of the secondary cell is unknown to the wireless communication device: setting a preliminary time reference of the secondary cell to equal a time reference of a primary cell of the carrier aggregation application; performing a synchronization signal based detection of the time reference of the secondary cell based on the preliminary time reference and one or more synchronization signals transmitted in the secondary cell; performing preliminary time reference based channel state measurements of the secondary cell based on the preliminary time reference and one or more reference signals transmitted in the secondary cell; setting, based on the synchronization signal based detection, a value of a channel quality indicator to either a nominal value or a value based on the preliminary time reference based channel state measurements; and transmitting a channel state information report comprising the channel quality indicator to the cellular communication network. An arrangement for a wireless communication device usable in a cellular communication network, adapted to attain time synchronization to a secondary cell of a carrier aggregation application is also disclosed. A modem comprising the arrangement and wireless communication device comprising the arrangement are also disclosed.

摘要： A technique for selecting a set of radio resources of a cellular telecommunications network for radio resource aggregation in a communication between the telecommunications network and a User Equipment (UE) is provided. As to a method aspect of the technique, a time offset relative to a primary radio resource for each of at least two secondary radio resources is monitored. The primary radio resource and the at least two secondary radio resources are provided by the telecommunications network for radio resource aggregation. Out of the at least two secondary radio resources, a set of radio resources is selected so that the time offsets monitored for the selected secondary radio resources fall within a time window having a width equal to or less than the threshold, if a spread of the monitored time offsets exceeds a threshold.

摘要： In one aspect of the teachings herein, network-side and device-side methods and apparatus identify a subset of frequency layers on which a wireless device performs regular inter-frequency scanning. The subset is identified from among a set of frequency layers that are candidates for inter-frequency measurement by the device. In an example, the wireless device scans the set of frequency layers and the corresponding scan results are used to select the best frequency layers in the set. In turn, the wireless device performs regular inter-frequency measurements on the frequency layers in the selected subset. Scanning thus can be understood as a mechanism for intelligently selecting preferred ones among a number of frequency layers that are candidates for inter-frequency measurement by the device.

摘要： The present invention relates to a method and apparatus for testing mobile terminals in an OFDMA system, in which all or part of available downlink radio resources in a cell are transmitted. A processing unit in a test apparatus splits a set of contiguous resource blocks into separate contiguous portions. A first contiguous portion of the set of resource blocks is allocated to users of a first type, and a second contiguous portion of the set of resource blocks is allocated to users of a second type. A transmitter in the test apparatus transmits test signals to the users of the first type and the second type using the at least one contiguous set of resource blocks.

摘要： Techniques and apparatus for handling timing alignment for a wireless device capable of aggregating carriers for uplink transmissions. In an example method, embodiments of which can be carried out in the wireless device or in a network node, a time difference between uplink transmission timings for a pair of timing advance groups (TAGs) for the wireless device is monitored, where each TAG comprises at least one serving cell. The method further includes determining whether the wireless device is able to support the time difference and, in response to determining that the wireless device is not able to support the time difference, excluding serving cells associated with one of the TAGS in the pair from uplink carrier aggregation.

摘要： According to one aspect of the teachings herein, a wireless device operating in a wireless communication network determines the difference in signal arrival times with respect to first and second cells, and the device and/or the involved wireless communication network uses the difference to control one or more aspects of Carrier Aggregation, CA, operation for the wireless device. For example, there may be a maximum timing difference defined for the wireless device, e.g., as a function of its inherent capabilities, and the wireless device may evaluate the timing difference of a second cell that is a candidate of aggregation into its CA configuration, or that may be a candidate for activation as a serving cell within a CA configuration, with respect to a first cell that is already in use as a serving cell for the wireless device.

摘要： The operating configuration at a node in a wireless communication network, at a neighboring node in the network, and/or at one or more wireless devices supported by the network, is updated based on determining timing information for an impending interruption of a radio link in the network to avoid erroneous operation during the impending interruption, which interruption is associated with an external system. The determination of interruption timing, which may be inferred, e.g., from detecting prior interruptions, or which may be known from information about the external system, and the modification of the operating configuration(s) permits the network to operate with greater stability, control, and accuracy during the interruptions than would be possible if the interruptions were simply treated as intermittent radio link failures.
