SCHEDULING SATELLITE DATA TRANSMISSIONS USING DIFFERING SETS OF GROUND STATIONS
The disclosure herein describes transmitting data from a satellite using a primary ground station and a set of secondary ground stations. An orbit of the satellite is determined over a schedule period and a subset of secondary ground stations is identified based on the determined orbit of the satellite, wherein secondary ground stations are configured to receive from the satellite and not transmit to the satellite. A transmission schedule associated with the satellite is then generated. For each secondary ground station of the subset, a time interval during which the satellite is within communication range is determined, an expected transmission rate is estimated, and the time interval and the expected transmission rate are included in the transmission schedule. The transmission schedule is provided to the satellite via the primary ground station, whereby the satellite is configured to transmit data to the subset of ground stations based on the transmission schedule.
SATELLITE 5G TERRESTRIAL AND NON-TERRESTRIAL NETWORK INTERFERENCE EXCLUSION ZONES
Various approaches for the deployment and use of communication exclusion zones, defined for use with a satellite non-terrestrial network (including within a low-earth orbit satellite constellation), are discussed. In an example, defining and implementing a non-terrestrial communication exclusion zone includes: calculating based on a future orbital position of a low-earth orbit satellite vehicle, an exclusion condition for communications from the satellite vehicle; identifying, based on the exclusion condition and the future orbital position, a timing for implementing the exclusion condition for the communications from the satellite vehicle; and generating exclusion zone data for use by the satellite vehicle, the exclusion zone data indicating the timing for implementing the exclusion condition for the communications from the satellite vehicle.
SYSTEM AND METHOD OF DOWNLINK-UPLINK TIMING RELATIONSHIP
A system and method of providing an enhanced downlink (DL)-uplink (UL) timing relationship. The system and method include identifying, by a first wireless communication device, an offset between a first time-domain tag at which the first wireless communication device detects a signal transmitted from a wireless communication node and a second time-domain tag at which the first wireless communication device applies the signal. In some embodiments, the offset includes at least one of a common offset portion or a user equipment (UE)-specific offset portion.
EFFICIENT SIGNALING IN NON-TERRESTRIAL AND TERRESTRIAL NETWORK DEPLOYMENT
Methods, apparatus, and systems for reducing signaling overhead and power consumption while ensuring mobility of communication devices in non-terrestrial network deployment as well as terrestrial network deployment are disclosed. In one example aspect, a wireless communication method includes receiving, by a communication device from a wireless communication node, information comprising a configuration parameter that corresponds to a length of a discontinuous reception cycle of the communication device. The method also includes performing, by the communication device, an operation based on the configuration parameter.
EDGE COMPUTING IN SATELLITE CONNECTIVITY ENVIRONMENTS
Various approaches for the integration and use of edge computing operations in satellite communication environments are discussed herein. For example, connectivity and computing approaches are discussed with reference to: identifying satellite coverage and compute operations available in low earth orbit (LEO) satellites, establishing connection streams via LEO satellite networks, identifying and implementing geofences for LEO satellites, coordinating and planning data transfers across ephemeral satellite connected devices, service orchestration via LEO satellites based on data cost, handover of compute and data operations in LEO satellite networks, and managing packet processing, among other aspects.
EXTENDING A TIME GAP RANGE FOR NON-TERRESTRIAL NETWORKS
A base station that determines a slot for uplink reception for a non-terrestrial network link between a base station and a user equipment is described. In exemplary embodiments, the base station determines a timing advance based on at least a random access preamble reception and determines an uplink offset based on the timing advance. The base station may further determine a candidate slot for an uplink reception based on at least the offset. In addition, the base station may determine if the candidate slot is available for the uplink reception. The base station may use the candidate slot for the uplink reception when the candidate uplink slot is available and may use the next available slot for the uplink reception when the candidate uplink slot is not available.
EXTENDING A TIME GAP RANGE FOR NON-TERRESTRIAL NETWORKS
A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.
SYSTEMS AND METHODS FOR A CONTROL STATION
A system and method for remote control of a mobile device is provided herein. The system includes a primary receiver for providing primary command and control of the mobile device; a secondary receiver for providing secondary command and control of the mobile device; the mobile device configured to respond to command and control signals sent by any of the primary receiver and the secondary receiver; and a relay platform for relaying the command and control signals throughout the system. The primary receiver may include an extended reality component.
Method and system for secure sharing of aerial or space resources using multilayer encryption and hosted payloads
A method and system for providing secure aerial or space communications. A general payload and a hosted payload are provided on a vehicle. The hosted payload encrypts a data packet that contains restricted data using a secure key to create an encrypted packet. The general payload encrypts the encrypted packet using a general key to create a multilayer-encrypted packet. The multilayer-encrypted packet is transmitted from the vehicle to a destination.
Dynamically estimating a propagation time between a first node and a second node of a wireless network
Apparatuses, methods, and systems for dynamically estimating a propagation time between a first node and a second node of a wireless network are disclosed. One method includes receiving, by the second node, from the first node a packet containing a first timestamp representing the transmit time of the packet, receiving, by the second node, from a local time source, a second timestamp corresponding with a time of reception of the first timestamp received from the first node, calculating a time difference between the first timestamp and the second timestamp, storing the time difference between the first timestamp and the second timestamp, calculating a predictive model for predicting the propagation time based the time difference between the first timestamp and the second timestamp, and estimating the propagation time between the first node and the second node at a time by querying the predictive model with the time.
