Title:
METHODS FOR SCHEDULING UPLINK TRANSMISSIONS FOR NON-TERRESTRIAL NETWORKS
Document Type and Number:
WIPO Patent Application WO/2023/014061
Kind Code:
A1
Abstract:
The various embodiments herein disclose methods and systems for uplink scheduling schemes for low-earth orbit (LEO) satellite based Non-Terrestrial Network (NTN). According to an embodiment, a zone-based scheduling (ZBS) scheme is described where the coverage area may be divided into a plurality of zones and independent scheduling-offsets may be allocated for each of the zones. The ZBS scheme improves upon the overall user latency by reducing the K2 and cell offset delay for low-propagation delay users within the NTN cells. At the same time, the impact of differential doppler may also be mitigated with such a zone-based allcoation strategy.
