A method of operating a satellite communications network, the method comprising: receiving from a satellite terminal a message; and storing the message contents in a satellite network database, the message indicating one or both of: (i) a list of communication satellites which are blocked to a satellite antenna or a portion of the field of view of the satellite antenna which is blocked, at a particular geographic location of the satellite antenna; and (ii) a list of communication satellites that are visible to the satellite antenna or a visible portion of the field of view of the satellite antenna, at a particular geographic location of the satellite antenna. A method of operating a satellite terminal having a satellite antenna. The method comprises controlling a beam of the satellite antenna to scan at least a portion of the field of view of the satellite antenna and locate at least one communication satellite or controlling a beam of the satellite antenna to perform a search to locate a communication satellite in the vicinity of a predicted location of the communication satellite, the predicted location being obtained from satellite ephemeris data. The method further comprises updating a satellite terminal database of communication satellites and their locations by recording the location of the located communication satellite in the satellite terminal database. The database and satellite ephemeris data may be used to determine a list of communication satellites which are blocked or a portion of the field of view of the satellite antenna which is blocked at the current location of the satellite antenna, or to determine a list of communication satellites that are visible to the satellite antenna or a visible portion of the field of view of the satellite antenna. The blocking information or visibility information may be transmitted to a satellite communication network and may be used to build a model of satellite communications network availability across a geographical area.

An electronic device (UE) comprising circuitry configured to compensate feeder link influence on the common TA (T.sub.com) in a transparent payload non-terrestrial network (NTN) configuration with a non-terrestrial network component (NT-RN) and an infrastructure equipment (gNB) tethered by the non-terrestrial network component (NT-RN).

In an integrated wireless communication network that includes terrestrial and non-terrestrial network devices, signaling that is indicative of information for application by a User Equipment (UE) in selection between multiple cooperation nodes to provide the UE with access to a non-terrestrial network device in the integrated wireless communication network is communicated. Cooperation may also or instead be applied in conjunction with a group handover procedure. For example, signaling that is indicative of information for application in making a handover determination by a cooperation node may be communicated. The handover determination may involve determining whether a first cooperation node is to perform a handover procedure to establish a connection to a second network device while a second cooperation node maintains its connection to a first network device; or the second cooperation node is to perform the handover procedure while the first cooperation node maintains its connection to the first network device.

This disclosure includes various examples and variations of communications networks that employ a satellite network with a plurality of HEO and/or MEO satellites. Regional data centers may be connected to the satellite via gateways. Edge devices may connect to the network through a plurality of edge micro data centers configured in a mesh network to provide distributed and dynamically allocatable compute and storage resources. Each edge micro data center may include a RAN controller to implement an O-RAN network (e.g., via a 5G Node B cell site) to provide end-user devices direct access to the distributed compute and storage resources of the mesh network of edge micro data centers without intermediary backhaul transport layers. Microwave links or other terrestrial network types may be employed to facilitate the mesh network of edge micro data centers.

Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.

In one embodiment, a method implemented in a wireless device, WD, includes receiving at least one first random access, RA, indicator that indicates information relating to a non-terrestrial network, NTN, access; and determining a random access, RA, based at least in part on the at least one first RA indicator. In one embodiment, a method implemented by a network node includes sending at least one first random access, RA, indicator that indicates information relating to a non-terrestrial network, NTN, access; and allowing the WD to perform a random access, RA, that is based at least in part on the at least one first RA indicator.

One method includes generating, by a wireless radiator, a plurality of selectable directional wireless communication links capable of providing connectivity across a plurality of cells, wherein each of the cells is spatially different from other cells, and wherein each of the cells covers a cell area, wherein a plurality of hubs are located within the cell area, generating, by a controller, a cell map, wherein the cell map maps which of the directional wireless links, which of the plurality cells, and which of the hubs are active as a function of time, thereby supporting a wireless communication link between the base station and the hubs of the cell area corresponding with the active directional wireless link, and providing the cell map to the base station and the hubs of each of the cells.

An offloading method, of a satellite-to-ground edge computing task, assisted by a satellite and a high-altitude platform can offload a computing task of a ground user equipment (GUE) to a low earth-orbit satellite (LEO SAT), to meet a computing requirement of the GUE and to reduce latency and energy consumption. The method includes four main steps: 1. The GUE selects an associated high-altitude platform. 2. The GUE uses multi-input and multi-output (MIMO) transmission to offload the computing task to the high-altitude platform. 3. The high-altitude platform may also use the MIMO transmission to offload the computing task of the GUE to the LEO SAT. 4. The high-altitude platform and the LEO SAT cooperate to process the computing task of GUE, and reasonably allocate a computing resource to reduce energy consumption; and in MIMO edge computing, the GUE or the high-altitude platform uses the same time-domain and frequency-domain resource .

A method is for establishing one or more links for an integrated access and backhaul for millimeter wave network. The network includes a high-altitude platform (HAP) as a first node and a terrestrial node as a second node. The method includes obtaining location information of the HAP in the network, determining that the HAP can be used to provide an additional access link or an additional backhaul link in the network in connection with the terrestrial node, controlling one or more transceivers of the terrestrial node to point towards the HAP according to the location information, and establishing the additional access link or the additional backhaul link between the HAP and the terrestrial node.

Systems for communicating data through a satellite are disclosed. The systems generally include a radio designed for terrestrial communications that is configured to uplink data to one or more satellites.
