CPC classification number: H04L7/0331

Abstract: In an embodiment, an apparatus includes an integrated circuit (IC) chip configured to receive a timing signal and a first reference clock signal and generate a first reference time signal based on the timing signal and the first reference clock signal. The IC chip is configured to generate a second reference time signal based on the first reference time signal and a second reference clock signal, different from the first reference clock signal The second reference time signal specifies a count of a number of cycles of the second reference clock signal starting from a particular cycle of the second reference clock signal. The IC chip is configured to synchronize one or more actions performed by the IC chip based on one or more of the first reference time signal or the second reference time signal.

Abstract: A method for downlink link adaptation includes receiving, from a satellite and at a user terminal, a first data packet data unit according to a first downlink modulation and coding scheme (MCS), computing an error vector magnitude data associated with the first data packet data unit, generating, based on one or more of the error vector magnitude data, user terminal signal-to-noise-ratio feedback based on a constant times a previous user terminal signal-to-noise-ratio and a current user terminal signal-to-noise-ratio, and transmitting an uplink packet data unit having a downlink block error rate and the user terminal signal-to-noise-ratio feedback. A satellite runs a link adaptation algorithm based on the user terminal signal-to-noise-ratio feedback and block error rate to generate a second downlink MCS. The method includes receiving at the user terminal a second data packet data unit according to the second downlink MCS for the user terminal. An uplink link adaptation algorithm is also disclosed.

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; requesting, based on the schedule, a handover from a beam of the satellite to a different beam of one of the satellite or a different satellite; processing packets transmitted over the beam of the satellite and/or the different beam of the 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.
