摘要： Methods and apparatuses exemplified in this disclosure provide mechanisms for a wireless communication device to indicate its Radio Access Technology (RAT) preferences to a wireless communication network, and for a wireless communication network to consider the RAT preferences of a given device when deciding which RAT the device will use. As a non- limiting example of the advantages flowing from these mechanisms, devices operating within a network that includes or is associated with multiple RATs can indicate their preferences for which RAT they use, while still allowing the network to retain control of the RAT selection decisions. Such flexibility offers significant advantages in 5G networks that provide tight integration between multiple RATs—e.g., between LTE and NR air interfaces. However, the methods and apparatuses disclosed herein are not limited to 5G networks.

摘要： A wireless communication device (140) and method therein for handling connection state changes in a wireless communication system (100) are disclosed. The wireless communication device (140) comprises at least two SIMs, in which a first SIM is in a first original connection state towards a first network node, a second SIM is in a second original connection state towards a second network node. The wireless communication device first determines whether a battery power in the wireless communication device is below a first threshold. When the battery power is below the first threshold, the wireless communication device selects a SIM out of the at least two SIMs for which to change its original connection state to a third connection state based on a parameter. The third connection state is a connection state implying lower power consumption for the wireless communication device compared to its original connection state. Then the wireless communication device performs a connection state change for the selected SIM from its original connection state to the third connection state.

摘要： Receiver resources are allocated based on how subframes are allocated within in a frame between downlink and uplink transmissions and how often the receiver is expected to report feedback information associated with the downlink transmissions. Additional time is available for processing received data blocks if the feedback information derived from those blocks must be reported later than expected due to the unavailability of uplink subframes. According to one embodiment, received signals are processed by receiving transmission configuration information indicating how downlink and uplink subframes are allocated within a frame in the time domain. Based on the transmission configuration information, the receiver determines whether a delay that exceeds a feedback reporting interval assigned to the receiver will occur when reporting feedback information associated with the downlink subframes. Receiver resources are allocated based on whether a delay will occur when reporting the feedback information.

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： A Radio Network Controller (RNC) is configured to send Radio Resource Control (RRC) messages to a mobile station using a selected downlink channel. Depending on the mobility rate of the mobile station, the RNC is configured to configure a signaling connection to use either a first downlink channel or a second downlink channel for transmitting the RRC messages. According to one embodiment, the RNC selects a dedicated channel when the mobile station has a high mobility rate, and selects a shared channel when the mobile station has a low mobility rate.

摘要： A beamforming method is disclosed of a multi-antenna transmitter configured for operation in a listen- before-talk (LBT) environment. The method comprises transmitting – in transmission resources of a collection of one or more transmission resources corresponding to an LBT sensing event – according to a primary emission pattern (e.g., a primary beam) having a main lobe in a primary angular direction associated with a channel path towards an intended receiver, and transmitting according to one or more secondary emission patterns. The one or more secondary emission patterns – when accumulated over the collection of transmission resources corresponding to the LBT sensing event – are configured to indicate channel occupancy in angular directions other than the primary angular direction. In some embodiments, the one or more secondary emission patterns comprises a plurality of secondary emission patterns (e.g., a plurality of secondary beams). Transmitting according to the one or more secondary emission patterns may comprise executing a sweep of the respective secondary beams over the collection of transmission resources corresponding to the LBT sensing event. In some embodiments, the one or more secondary emission patterns consists of a single secondary emission pattern (e.g., an omni-directional emission pattern). Corresponding apparatus, transmitter, network node, wireless communication device, and computer program product are also disclosed.
