(EN) NARROWBAND TIME-DIVISION DUPLEX FRAME STRUCTURE FOR NARROWBAND COMMUNICATIONS
(FR) STRUCTURE DE TRAME EN DUPLEX À RÉPARTITION DANS LE TEMPS À BANDE ÉTROITE POUR COMMUNICATIONS À BANDE ÉTROITE
Abstract
(EN) There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband communication frame structure comprising a FDD frame structure or a TDD frame structure and a narrowband TDD frame structure configuration for narrowband communications from a group of narrowband TDD frame structures configurations. The apparatus may determine one or more narrowband carriers and subframes within the one or more narrowband carriers to transmit at least one of a BCH or a SIB1 based on the narrowband communication frame structure or the TDD frame structure configuration. The apparatus may transmit a PSS, an SSS, and at least one of a BCH or an SIB1 using the narrowband TDD frame structure determined for the narrowband communications. In one aspect, a carrier used for transmitting the BCH and/or the SIB may be different than a carrier used to transmit one or more of the PSS or the SSS. In another aspect, a narrowband carrier used for transmitting the BCH may be different than a narrowband carrier used to transmit one or more of the PSS or the SSS.
(FR) Il existe un besoin de prendre en charge une structure de trame TDD à bande étroite pour des communications à bande étroite. La présente invention concerne une solution qui consiste à prendre en charge une ou plusieurs structures de trame TDD à bande étroite pour des communications à bande étroite. Un aspect de l'invention décrit un procédé, un support lisible par ordinateur et un appareil. L'appareil peut déterminer une structure de trame de communication à bande étroite comprenant une structure de trame FDD ou une structure de trame TDD et une configuration de structure de trame TDD à bande étroite pour des communications à bande étroite à partir d'un groupe de configurations de structures de trame TDD à bande étroite. L'appareil peut déterminer une ou plusieurs porteuses à bande étroite et des sous-trames à l'intérieur de la ou des porteuses à bande étroite pour transmettre un BCH et/ou un SIB1 sur la base de la structure de trame de communication à bande étroite ou de la configuration de structure de trame TDD. L'appareil peut transmettre un PSS, un SSS ainsi qu'un BCH et/ou un SIB1 à l'aide de la structure de trame TDD à bande étroite déterminée pour les communications à bande étroite. Selon un aspect, une porteuse utilisée pour transmettre le BCH et/ou le SIB peut être différente d'une porteuse utilisée pour transmettre le PSS et/ou le SSS. Selon un autre aspect, une porteuse à bande étroite utilisée pour transmettre le BCH peut être différente d'une porteuse à bande étroite utilisée pour transmettre le PSS et/ou le SSS.
