  • Patent number: 12375988
    Abstract: Systems, methods, and non-transitory media are provided for low latency handovers. An example method can include receiving, by a user terminal associated with a cell served by a satellite, a schedule of communications between the user terminal and one or more satellites, wherein the one or more satellites comprises the satellite and a different satellite, and wherein the schedule of communications is obtained by the user terminal from the satellite; requesting, based on the schedule, a handover from a beam of the satellite to a different beam of one of the satellite or the different satellite; performing the handover from the beam of the satellite to the different beam of the one of the satellite or the different satellite; and after the handover, transmitting, by the user terminal, one or more packets via the different beam of the one of the satellite or the different satellite.

  • Publication number: 20250183997
    Abstract: In an embodiment, a method includes generating an initial network entry request. The method further includes in response to the initial network entry request, finding, via a user terminal, a satellite based on a search of a sky. The search of the sky comprises sequentially changing a beam pointing direction of the user terminal. The satellite is assigned to downlink to a geographic cell associated with the user terminal. The method includes generating an uplink radio frame associated with the initial network entry request at a particular portion of the uplink radio frame for the satellite.

  • Patent number: 12218742
    Abstract: In an embodiment, a user terminal includes a communication module (CM) configured to generate an initial network entry request; an antenna assembly configured to find, in response to the initial network entry request, a satellite based on a search of a sky. The search of the sky includes sequentially changing a beam pointing direction of the antenna assembly. The satellite is assigned to downlink to a geographic cell associated with the user terminal. The user terminal includes a media access control (MAC) layer component configured to generate an uplink radio frame including a random access channel (RACH) request associated with the initial network entry request at a particular portion of the uplink radio frame for the satellite.

  • Patent number: 11949496
    Abstract: Systems, methods, and non-transitory media are provided for low latency handovers. An example method can include receiving, by a satellite, a schedule of communications between the satellite and one or more gateways; requesting, based on the schedule, a handover from a link between the satellite and a gateway to a different link between the satellite and the gateway or a different gateway; prior to a completion of the handover, processing packets bicasted over the link between the satellite and the gateway and the different link between the satellite and the gateway or the different gateway; performing the handover from the link between the satellite and the gateway to the different link between the satellite and the gateway or the different gateway; and after the handover, transmitting, by the satellite, one or more packets via the different link between the satellite and the gateway or the different gateway.
