Samsung patents 5G timing fix for satellite-connected devices
Samsung has been granted a patent for a method that helps mobile devices stay in sync with base stations in non-terrestrial networks, such as those involving satellites. The system divides uplink transmissions into smaller groups and adjusts the timing for each group to account for signal delays.
In the filing’s own words
The present disclosure relates to a pre-5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). The disclosure provides a synchronization method, apparatus, device and computer readable storage medium, the method being performed by a user device UE. A method includes transmitting a first portion of repetitions of an uplink transmission based on a first value of an uplink synchronization parameter, the first portion of repetitions including a single repetition or multiple repetitions; determining a second value of the uplink synchronization parameter by adjusting the first value of the uplink synchronization parameter; and transmitting a second portion of repetitions of the uplink transmission based on the second value of the uplink synchronization parameter, the second portion of repetitions including a single repetition or multiple repetitions.
What exactly they claim (claim 1)
1. A method performed by a user equipment (UE) in a communication system, the method comprising: receiving, from a base station, a first configuration of a portion of an adjustment time unit for uplink transmissions in a non-terrestrial network (NTN); identifying a first number of subframes corresponding to the portion based on the first configuration; and transmitting, to the base station, the uplink transmissions on a plurality of subframes corresponding to a plurality of portions based on adjusting a timing advance per each of the plurality of portions among the plurality of subframes on which the uplink transmissions are transmitted, wherein each of the plurality of portions corresponds to the first number of subframes.
