There is provided a system including: a control device mounted on an aircraft and configured to control the aircraft, the aircraft having a battery, and a wireless device configured to use power stored in the battery to provide a wireless communication service to a user terminal; and a module that is physically attachable to and detachable from the control device, in which the control device has a housing that includes a module attachment and detachment unit, and an electrical connection unit configured to electrically connect the module to the battery when the module is attached to the module attachment and detachment unit, and the module has, a power receiving unit configured to receive power from the battery, and a communication processing unit configured to use the power received by the power receiving unit to communicate with the wireless device.

A space-based communications network (100) includes at least one central ground station (116) having a transceiver that is configured to communicate with satellites, such as cube satellites (110). The cube satellites (110) form an ad hoc network of orbital cube satellites, in which each of the cube satellites (110) communicate with each other. One of the cube satellites communicates with the ground station (116). A ground-based control system (1000) communicates with the central ground station (116). The control system (1000) continuously determines a configuration of the ad hoc network (100) and communicates network control information for the cube satellites (110) to maintain communications in the ad hoc network (100). The cube satellites (110) disseminate the network control to each other via the ad hoc network (100).

A method is provided for simultaneously transmitting a plurality of signals from a LEO satellite towards a plurality of ground terminals located within a pre-defined range of distances from the LEO satellite, wherein the plurality of signals have a pre-defined overall capacity; at least two of the plurality of signals have each a power level that is different from a power level of the other of the at least two signals; and each signal transmitted to a respective ground terminal is selected so as to ensure that its power level is the lowest from among the signals that are simultaneously transmitted, yet the selected signal has a sufficient power to enable its proper reception at a distance which extends between the respective ground terminal and the LEO satellite.

An optimisation method is presented for the transmission of data along any radio frequency link which can be split into distinct transmission blocks, an example being a beam hopping system. By reordering the packets to be transmitted, it is possible to send packets either at, or nearer to, their optimal modulation and encoding configuration. This will allow for a higher bit to symbol conversion for the majority of packets and hence more data bits can be sent for the same number of symbols.

Systems and techniques are provided for wireless communications at a network entity. For example, then systems and techniques can include determining, at the network entity, a transmission timing compensation between a first reference signal and a second reference signal. The first reference signal can be transmitted using a first communication link. The second reference signal can be transmitted based on an offset determined based on the transmission timing compensation, wherein the second reference signal is transmitted suing a second communication link. The offset can be used to offset transmission of the second reference signal from transmission of the first reference signal.

A terminal computer includes a processor and a memory. The memory stores instructions executable by the processor to determine an initial power back-off value for establishing a communication link to a satellite as a function of a distance of a location of a satellite terminal antenna within a satellite beam footprint from a specified reference point within the satellite beam footprint, and to initiate communication with the satellite based on the determined initial power back-off value.

Apparatuses, methods, and systems for a satellite wireless communication system are disclosed. One system includes a base station, a satellite, a beam management controller, and a plurality of wireless devices. The base station is configured to wirelessly communicate according to a schedule between the base station and each of the plurality of wireless devices within a scheduling frame. The satellite is operative to form a plurality of beams between the satellite and the wireless devices and support a wireless satellite link between the base station and the wireless devices through the plurality of beams. The beam management controller is operative to assign beam allocations for the scheduled wireless communication between each of the wireless devices and the base station that is time aligned with the scheduling frame, wherein each of the beam allocations includes an assignment to at least one of the plurality of beams.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a default value for a radio parameter used for communicating with a network node based at least in part on whether the network node is a terrestrial network (TN) node or a non-terrestrial network (NTN) node, an orbit type associated with the network node, or a coverage type associated with the network node. The UE may transmit a communication, e.g., to the network node based at least in part on the default value for the radio parameter. Numerous other aspects are described.

An operation method of a first communication node in a communication system may comprise receiving one or more transport blocks (TBs) from a second communication node based on transmission parameters in an aggregated transmission period #n; generating decoding results for the one or more TBs; generating information required for changing the transmission parameters based on the decoding results; and transmitting the required information to the second communication node, wherein n is a natural number.

Wireless communication systems and methods are provided that include at least one base transmitter unit, at least one repeater unit, at least one receiver, and an artificial intelligence unit. The base transmitter unit is configured to transmit a data signal. The repeater unit is in communication with the transmitter and is configured to transmit the data signal via sky wave propagation. The receiver is in communication with the transmitter and the repeater and is configured to receive the data signal. The artificial intelligence unit monitors ionospheric conditions in the area and controls the data signal, making adjustments so the data signal overcomes skip zones. The adjustments may include automatically adjusting the power and position of the antenna array to re-route the data signal and/or dynamically changing the frequency of the data signal.
