SIGNALING DESIGN OF ENHANCED HANDOVER SUPPORT FOR DRONES IN A CELLULAR NETWORK
To configure a UE for handover between a source evolved Node-B (eNB) and a target eNB using aerial communications in a cellular network, the UE processing circuitry is to decode measurement configuration information from the source eNB. The measurement configuration information includes a plurality of height thresholds associated with aerial height of the UE. A measurement report is encoded for transmission to the source eNB. The measurement report includes the aerial height of the UE and the measurement report generation triggered based on one or more triggering events associated with the plurality of height thresholds. RRC signaling from the source eNB is decoded, the RRC signaling including a handover command. The handover command is based on a handover decision by the source eNB using the measurement report. A handover from the source eNB to the target eNB is performed based on the handover command.
UE, network node and method for enabling GNSS measurements
The present disclosure relates to a method performed by a UE for enabling GNSS measurements. The UE and a network node are included in a NR communications network, and the NR communications network includes a NTN component. The UE performs a GNSS measurement according to a rule and using a GNSS receiver included in the UE. At least one of a UE position and an absolute time is an output of the GNSS measurement or is derivable from the GNSS measurement.
Access Node, Control Device and Method Thereof
The present disclosure relates to an access network node for a wireless communication system. The access network node is configured to act as a source access network node or as a target access network node, and comprises a transceiver configured to receive a handover instruction from a control device, the handover instruction comprising a handover time instance for a user device, a processor configured to serve the user device by maintaining a data connection with the user device until the handover time instance, and share an Automatic Repeat Request/Hybrid Automatic Repeat Request, ARQ/HARQ, process with a target access network node for the user device; or serve the user device by maintaining a data connection with the user device after the handover time instance, and share a ARQ/HARQ process with a source access network node for the user device.
SYSTEMS AND METHODS FOR IMPLEMENTING HANDOVERS IN A VEHICLE COMMUNICATION SYSTEM
A vehicle communication system is provided. The vehicle communication system includes a first communication system, a second communication system and a controller. The first communication system is configured to communicate via first type of communication signal to at a least one first remote communication system. The second communication system is configured to communicate via a second type of communication signal to the at least one second remote communication system. The controller is configured to select between use of the first and second communication systems based on at least one of a predicted availability of first and second communication coverage during a travel route and an anticipated number of handovers needed in a defined window of time.
Wedge shaped cells in a wireless communication system
Aspects described herein relate to a network for providing air-to-ground wireless communication in various cells. The network includes a first base station array, each base station of which includes a respective first antenna array defining a directional radiation pattern that is oriented in a first direction, wherein each base station of the first base station array is disposed spaced apart from another base station of the first base station array along the first direction by a first distance. The network also includes a similar second base station array where the second base station array extends substantially parallel to the first base station array and is spaced apart from the first base station array by a second distance to form continuous and at least partially overlapping cell coverage areas between respective base stations of the first and second base station arrays.
Systems and methods for handover of mobile devices, radio cells and space vehicles for mobile satellite wireless access
Access, mobility management and regulatory services are supported for satellite access to a Fifth Generation (5G) core network (5GCN). Signaling including data and voice for radio cells supported by a satellite is transported between UEs and a core network via an earth station. When the satellite is transferred to a new earth station, the signaling can be transferred to the new earth station and possibly to a new base station. The UEs may remain with their current radio cells with a regenerative satellite or be assisted to remain with their current radio cells with a transparent satellite. The signaling transfer between the earth stations may occur at a Level 1 or Level 2. A modified handover procedure may be used with a regenerative satellite with split architecture when there is a change of base station.
Base station, communication system, communication method, and program
A base station that includes a memory for storing computer readable code and a processor operatively coupled to the memory is described herein. The processor is configured to acquire other base station delay information, which is information associated with communication delays predicted for communications between the other base stations and a terminal apparatus. The processor is further configured to notify the terminal apparatus of the acquired other station delay information. The terminal apparatus acquires the other station delay information from the base station.
HANDOVER FOR UNMANNED AERIAL VEHICLES
Techniques are described for improving handover performance in the context of UEs incorporated into unmanned aerial vehicles (UAVs, a.k.a., drones). A database is constructed that relates locations in a three-dimensional flying space to handover information that may include optimum scanning directions, optimum handover parameters, and/or optimum target cells to be monitored for possible handover.
Satellite network switching
A satellite network comprises networks nodes including multiple satellites, multiple gateways, additional servers and a mobile vehicle (e.g., an aircraft). All of (or a subset) of the network nodes include switches. The network implements a software defined network that includes a mobility manager as part of the management plane, a network controller as part of the control plane, and the switches on the network nodes as the data plane. In one embodiment, the switches communicate using an Open Flow communications protocol and make routing decisions based on flow tables. The mobility manager communicates with, and manages, the switches via the network controller. The mobility manager proactively generate updates to flow tables based on satellite ephemeris data for the multiple satellites and itinerary data for the aircraft, and pushes the updates to the switches in response to determining that the aircraft needs to be handed off between satellites.
METHOD AND APPARATUS FOR MANAGING CELL RESELECTION PRIORITY OF TERMINAL IN NEXT-GENERATION MOBILE COMMUNICATION SYSTEM
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. The disclosure relates to a method performed by an unscrewed aerial vehicle (UAV) terminal in a wireless communication system, including receiving first system information, camping on a first cell supporting a UAV based on the first system information, in case that an altitude of the UAV terminal is greater than an altitude threshold, receiving, from the first cell, second system information including cell reselection information, determining a cell reselection priority based on a frequency identical to a first frequency of the first cell and the cell reselection information included in the second system information, and performing a measurement based on the cell reselection priority.
