Methods, systems, and apparatus, including computer programs encoded on computer storage media, for dynamically reducing an aperture size to reduce overhead. In some implementations, a server can receive a first transmission from a first terminal through a communication network. The server can determine a timing offset associated with the first terminal based on the first transmission. The server can determine an aperture window size for an aperture window for the first terminal based on the determined timing offset associated with the first terminal. The server can generate allocation data that assigns communication resources to one or more terminals that includes the first terminal, the allocation data being based on the determined aperture window size for the first terminal. The server can communicate with the one or more terminals to indicate the communication resources respectively allocated to the one or more terminals.

A system and method for compensating for attenuation of carrier power by a transmission path. The method includes defining a path from a gateway to a measurement tap, where the path may include an output port of the gateway and path components used to reach the measurement tap; sweeping, in bands, an RF spectrum served by the RFT by sending a signal at a respective band and a band power from the output port over the path; measuring, at the measurement tap, a power metric for each of the bands; capturing, for each of the bands, power level (PL) data including a frequency start of the respective band, a frequency end of the respective band, the respective band power and the respective power metric at the measurement tap; and setting a carrier power level (CPL) of a carrier having a frequency start and a frequency end, where the CPL is based on the PL data associated with one more of the bands included in the frequency start and the frequency end, where the path components may include one or more connecting cables, one or more switches, and one or more equipment in the path.

A base station transmits a signal transmission to a mobile broadband (MBB) user equipment (UE) device and to a machine type communication (MTC) device that is in close proximity to the MBB UE device where the signal transmission includes control channel and a data channel. The control channel includes common location dependent control information that applies to the MTC device and the MBB UE device because they are at the same location.

This application provides an example satellite, an example terminal device, an example satellite communication system, and an example satellite communication method. One example satellite communication method includes obtaining, by a first satellite, at a media access control (MAC) layer, data and/or signaling, where the first satellite is a low orbit satellite. When MAC-layer first processing needs to be performed on the data and/or the signaling, performing, by the first satellite, the MAC-layer first processing on the data and/or the signaling. The MAC-layer first processing includes at least one of hybrid automatic repeat request (HARQ) function processing or random access (RA) function processing.

Apparatuses, methods, and systems of hub communication with a satellite network or a terrestrial network are disclosed. One method includes detecting presence of the satellite network, detecting, by the hub, presence of a terrestrial network, selecting to connect to one of the satellite network or the terrestrial network based on a priority ruleset, estimating a propagation delay between the hub and a base station of the satellite network when the satellite network is selected, adjusting a timing offset between transmit and receive radio frames at the hub based on whether the satellite network or the terrestrial network is selected, and based at least on the propagation delay and a frame offset between uplink and downlink frames at base station, and communicating with the base station of the satellite network or a base station of the terrestrial network.

In one implementation, a method for scheduling beams of an antenna on a satellite during a defined time period includes calculating a beam score for each beam based on the expected gain of the beam and determining that the number of beams having non-zero beam scores during the defined time period is less than a threshold value. In addition, the method also includes accessing a set of beam weights for each of multiple different candidate beam patterns, and, for each set of weights, multiplying individual beam weights by corresponding beam scores, and generating a candidate beam pattern score by calculating a sum of the products of the beam weights and corresponding beam scores. The method further includes comparing the candidate beam pattern scores, selecting a particular one of the candidate beam patterns, and scheduling the selected beam pattern for the defined time period.

A wideband transceiver for a gateway is presented. The wideband transceiver may interface with the gateway’s processors over an interface that carries data encapsulated in baseband frames. The wideband transceiver may comprise a modulator and a high power amplifier and may improve a transmitted signal quality and may utilize a wideband for wireless communications, for example, for a satellite communication system.

A method comprises a preprocessing step consisting, in the gateway station, in pre-segmenting the data as a function of the carrier frequency which is dedicated to them on the downlink DL, in reassembling and in encapsulating the pre-segmented data in successive basic frames DL BB-Frames, that can be transmitted over the downlink, each basic frame DL BB-Frame of the downlink being encapsulated by addition of a specific transport header DL BB-TH on the downlink and a data field, and a step consisting, in the gateway station, in incorporating the different basic frames DL BB-Frames of the downlink in the data field of the different basic frames UL BB-Frames of the uplink.

At least one satellite provides access to an internet via one or more spatial beams of the satellite, each beam covering a respective area of a geographic region and thereby providing said internet access to a plurality of respective users in the respective area. A plurality of bandwidth pools are allocated, from which bandwidth is used by the respective users in using the internet access. The sizes of two or more of these bandwidth pools are then dynamically adapted by temporarily re-allocating currently unused bandwidth from one or more of the pools to one or more others of the pools, automatically in response to current demand for the internet access from at least one of the two or more pools.
