Title (EN) CHANNEL PARTITIONING FOR FREQUENCY-HOPPING NARROWBAND IOT
(FR) PARTITIONNEMENT DE CANAL POUR IOT À BANDE ÉTROITE À SAUT DE FRÉQUENCE
Abstract:
(EN) According to some embodiments, a method for use in a frequency-hopping wireless transmitter for transmitting in unlicensed spectrum comprises: obtaining a configuration for a plurality of frequency channels in unlicensed spectrum; and transmitting a data transmission according to a frequency-hopping pattern across the plurality of frequency channels. The configuration for the plurality of frequency channels comprises a first subset of frequency channels for downlink transmission and a second subset of frequency channels for uplink transmission. The frequency channels in the first and second subsets are mutually exclusive. In some embodiments the first and second subset of frequency channels each comprise 160 frequency channels in the 2.4 GHz band, or 50 frequency channels in the 915 MHz band.
(FR) Selon certains modes de réalisation, l'invention concerne un procédé destiné à être utilisé dans un émetteur sans fil à saut de fréquence pour une transmission dans un spectre sans licence, le procédé consistant : à obtenir une configuration concernant une pluralité de canaux de fréquence dans un spectre sans licence ; et à transmettre une transmission de données selon un motif de saut de fréquence sur une pluralité de canaux de fréquence. La configuration concernant la pluralité de canaux de fréquence comprend un premier sous-ensemble de canaux de fréquence pour une transmission de liaison descendante et un second sous-ensemble de canaux de fréquence pour une transmission de liaison montante. Les canaux de fréquence dans les premier et second sous-ensembles sont mutuellement exclusifs. Dans certains modes de réalisation, les premier et second sous-ensembles de canaux de fréquence comprennent chacun 160 canaux de fréquence dans la bande de 2,4 GHz, ou 50 canaux de fréquence dans la bande de 915 MHz.
