Title (EN) MULTIPLEXING UPLINK TRANSMISSIONS WITH TRANSMIT DIVERSITY WITH SINGLE CARRIER WAVEFORM
(FR) MULTIPLEXAGE DE TRANSMISSIONS EN LIAISON MONTANTE AYANT UNE DIVERSITÉ DE TRANSMISSION AVEC FORME D'ONDE DE PORTEUSE UNIQUE
Abstract:
(EN) Methods, systems, and devices for wireless communication are described that support multiplexing uplink transmissions with transmit diversity with a single carrier waveform. Two or more UEs may be configured to use space time block codes (STBC) for transmissions using multiple uplink antennas. A first UE may be configured to use a first STBC for a first uplink transmission. An orthogonal cover code (OCC), such as a Walsh code, may be applied to the first STBC to generate a second STBC, and a second UE may use the second STBC for a second uplink transmission. The first UE and the second UE may concurrently transmit the first uplink transmission and the second uplink transmission. The first STBC and the second STBC may be applied across multiple OFDM symbols, or may be applied within an OFDM symbol on a modulated symbol level.
(FR) L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil qui prennent en charge le multiplexage de transmissions en liaison montante ayant une diversité de transmission avec une forme d'onde de porteuse unique. Deux UE ou plus peuvent être configurés pour utiliser des codes de bloc de temps d'espace (STBC) pour des transmissions à l'aide de multiples antennes en liaison montante. Un premier UE peut être configuré pour utiliser un premier STBC pour une première transmission en liaison montante. Un code de couverture orthogonal (OCC), tel qu'un code de Walsh, peut être appliqué au premier STBC pour générer un second STBC, et un second UE peut utiliser le second STBC pour une seconde transmission en liaison montante. Le premier UE et le second UE peuvent transmettre simultanément la première transmission en liaison montante et la seconde transmission en liaison montante. Le premier STBC et le second STBC peuvent être appliqués à travers de multiples symboles OFDM, ou peuvent être appliqués à l'intérieur d'un symbole OFDM sur un niveau de symbole modulé.
