Document Type and Number:
WIPO Patent Application WO/2022/078498
Kind Code:
A1
Abstract:
Some present implementations provide a method for a user equipment (UE) connected to a non-terrestrial network (NTN). The method may receive, from a base station (BS) of the NTN at a downlink (DL) slot n, a timing advance (TA) command. The method may also adjust a timing of uplink (UL) transmissions to the BS according to the received TA command. The method may also include applying the adjusted timing for the UL transmissions by performing the UL transmissions from a beginning of a UL slot n + k + 1 + K offset. K offset may be a common delay broadcast by the BS to a plurality of UEs connected to the NTN including the UE, and k may be an additional delay specific to the UE.
