摘要： Embodiments of the present application are related to a method and apparatus for sequence determination in wireless transmission. According an embodiment of the present application, an exemplary method includes: receiving configuration information indicating at least one offset value associated with a kind of sequence, wherein each offset value corresponds to a second time domain index offset relative to a first time domain index determined based on synchronization signal block (SSB) associated with the kind of sequence; determining at least one second time domain index associated with the kind of sequence based on the at least one offset value correspondingly; and determining at least one sequence correspondingly based on the at least one second time domain index. Accordingly, embodiments of the present application can allow interference randomization during sequence generation in spite of the unfavorable impact on time domain index.

摘要： Systems and methods are provided for enhanced ship-based network connectivity using a content delivery network (CDN) edge server. An example method includes receiving user requests from user devices in wireless communication with a system, with the user requests being associated with applications executing on the user devices. An operating status associated with a satellite communication system is determined, the operation status being indicative of the satellite communication system having bandwidth and/or connectivity to route the user requests via a satellite network. Based on the operating status being negative, a first subset of the user requests is queued for transmission. A second subset of the user requests are responded to using an edge cache. Based on the operating status being positive, the user requests are transmitted via the satellite network to a shore-based system, the shore-based system routing the user requests to web applications associated with different functionality.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A telecommunications platform comprises an antenna configured to generate a plurality of communications beams within a respective footprint on the surface of the Earth, wherein each communications beam provides data communications services over a respective cell coverage area on the surface of the Earth. The telecommunications platform further comprises a processor configured to control the plurality of communications beams of the antenna to form the respective cell coverage areas in a fixed cell pattern that remains essentially fixed relative to the surface of the Earth, such that, as the telecommunications platform travels through an orbit around the Earth, the footprint of the antenna sweeps across the fixed cell pattern and provides the communications services via the cell coverage areas of the fixed cell pattern that are within the footprint of the antenna at any given point in time.

摘要： Aspects of the subject disclosure may include, for example, a cost-efficient wireless framework for delivering TV services (e.g., live TV services). The wireless framework can include a mix of wireless access technologies (e.g. Satellite, WiFi and/or LTE overlay links). TV content (e.g., live TV content) can be injected into the network at a few locations (e.g., residential locations) using satellite antennas (e.g., satellite dishes). The content can then be further distributed to other homes using a house-to-house WiFi network and/or via an overlay LTE network. Other embodiments are disclosed.

摘要： A broadband multibeam satellite radio communication system is configured to cover a geographical service area that is broken down into a plurality of transmission spots that are each made up of a central internal area and a peripheral area. A first polarization state and a second polarization state are respectively allocated to the spots of a first grid G1 and the spots of the second grid G2. One and the same main band BP of frequencies is allocated wholly to each central internal area. The coverage of the quadruple points service area is a pavement of elemental useful surfaces or coverage meshes having the shape of a parallelogram.
