Abstract:
The invention relates to a method for dynamically indicating a TDD re-configuration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re- configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication. The most suitable drawing: Fig.9.
Abstract:
The present invention relates to adaptive modulation and coding scheme selection and signaling in a communication system. In particular, a modulation and coding scheme to be used for transmission of a data is selected from a set of predetermined modulation and coding schemes. The predetermination of the set is performed by selecting the set from a plurality of predefined sets. The sets have the same size, so that a modulation and coding selection indicator signaled to select the modulation and coding scheme may be advantageously applied to any of the selected sets. Moreover, a second set includes schemes with a modulation not covered by the schemes of a first set, and which is of a higher order than any modulation in the first set.

Abstract:
La presente divulgación se refiere a la transmisión de bloques de transporte en subtramas de una longitud predefinida dentro de un sistema de comunicación inalámbrica. Se recibe (el equipo de usuario es el transmisor) o se genera (la estación base es el transmisor) una información de control de enlace descendente que incluye una concesión de recursos que comprende una modulación predeterminada y un tamaño de bloque de transporte predeterminado. A continuación, se genera un bloque de transporte que incluye datos codificados por canal que se van a transmitir en una subtrama con la modulación predeterminada y el tamaño de bloque de transporte predeterminado. Se realiza una detección en las subtramas y, en función de ello, se determina si una subtrama parcial o una subtrama completa está disponible para la transmisión del bloque de transporte generado. Finalmente, el bloque de transporte se transmite con una modulación modificada diferente de la modulación predeterminada si la subtrama parcial en lugar de la completa está disponible. En consecuencia, en el receptor, se recibe la concesión (el equipo de usuario es el receptor) o se genera (la estación base es el receptor), se determina el tamaño de la subtrama en la que se espera la recepción y, a continuación, se recibe el bloque de transporte con una modulación modificada si solo está disponible la subtrama parcial.

Abstract:
The present disclosure relates to transmitting (1411, 1431) transport blocks in subframes of a predefined length within a wireless communication system. A downlink control information including a resource grant comprising a predetermined modulation and a predetermined transport block size is received (user equipment is the transmitter) or generated (base station is the transmitter). Then transport block including channel coded data to be transmitted in a subframe with the predetermined modulation and the predetermined transport block size is generated. Sensing is performed in the subframes and based thereon, it is determined whether a partial subframe or a complete subframe is available for transmission of the generated transport block. Finally, the transport block is transmitted (1426, 1437) with a modified modulation different from the predetermined modulation if the partial rather than complete subframe is available. Correspondingly, at the receiver, the grant is received (user equipment is receiver) or generated (base station is the receiver), the size of the subframe in which the reception is expected is determined and then the transport block is received with a modified modulation if only the partial subframe is available.
