SYSTEMS AND METHODS FOR THROUGHPUT ENHANCEMENT IN NON-TERRESTRIAL NETWORKS USING ORTHOGONAL COVER CODE SPREADING

Abstract: systems and methods for throughput enhancement in non-terrestrial networks (ntns) using orthogonal cover code (occ) spreading are discussed. a user equipment (ue) of an ntn that communicates with a base station over a service link of the ntn receives, from the base station, a downlink control information (dci) that indicates a dynamic uplink grant for a physical uplink shared channel (pusch), where the dci communicates an occ sequence index; identifies, using the occ sequence index, a first occ sequence for the first pusch from a set of occ sequences of an occ size corresponding to the occ sequence index; spreads data for the pusch into the pusch using the first occ sequence; and sends, to the base station, over the service link, the pusch according to the dynamic uplink grant. cases using configuration information for a configured uplink grant are also discussed. corresponding base station behaviors are discussed.
