Abstract: Provided is a terminal apparatus that, when two terminals having mutually different subframe structure patterns are coexistent, can suppress DCI scheduling constraints of those terminals in a base station. In a terminal (200), a signal separation unit (203) separates, from a received signal, both a response signal assigned to a first resource determined on the basis of a number of resources associated with the first subframes in which the signal was received and downstream control information assigned to a second resource. It should be noted that at a timing when both a first structure pattern that has been set in the terminal (200) and a second structure pattern that has been set in another terminal that cannot change the setting of the structure pattern are the first subframes, the signal separation unit (203) uses a number of resources associated with the first subframes of the second structure pattern.

Abstract: Provided is a terminal device with which deterioration in hybrid automatic repeat request (HARQ) retransmission performance can be inhibited by continuing a downlink (DL) HARQ process for DL data before and after changing the uplink link-DL configuration. In this device, a decoder (210) stores, in a retransmission buffer, DL data transmitted from a base station, and decodes the DL data, and a wireless transmitter (222) transmits a response signal generated using a DL-data-error detection result. A soft buffer is partitioned into a plurality of regions for each retransmission process on the basis of the highest values among retransmission process numbers respectively stated in a plurality of configuration patterns which can be set in the terminal (200).

Abstract: The purpose of the present invention is to avoid ACK/NACK collision in a system in which E-PDCCH control information is transmitted, increase the utilization efficiency of ACK/NACK resources, and suppress unnecessary PUSCH band reduction. A wireless communications terminal having a configuration comprising: a reception unit that receives control signals including ACK/NACK indexes, via an expanded physical downlink control channel; a control unit that determines, on the basis of the ACK/NACK indexes, whether to use a dynamically allocated dynamic ACK/NACK resource or a specified resource specified beforehand, to send downlink data ACK/NACK signals; and a transmission unit that sends the ACK/NACK signals using the dynamic ACK/NACK resource or the specified resource, as determined.

Abstract: dispositivo terminal e método de controle de retransmissão. a presente invenção refere-se a um dispositivo terminal que é capaz de aprimorar as características de um sinal de resposta que tem características de transmissão pobre quando arq é utilizado em comunicação com o uso de uma banda de unidade de enlace ascendente e uma pluralidade de bandas de unidade de enlace descendente associada à banda de unidade de enlace ascendente. no momento da seleção de canal, uma unidade de controle (208) seleciona um recurso usado no envio de um sinal de resposta a partir dos recursos de pucch específicos notificados antecipadamente a partir de uma estação base (100) e recursos de pucch mapeados em um cce, e controla a transmissão do sinal de resposta. uma unidade geradora de sinal de resposta (212) suporta a sinalização implícita em relação a qualquer dado sinal de resposta e, ao mesmo tempo em que suporta a queda de lte de 2cc, usa um método de mapeamento que, entre bits, suaviza o número de recursos de pucch que pode determinar ack/nack simplesmente ao determinar o recurso de pucch em relação ao qual o sinal de resposta havia notificado.

Abstract: In the event that uplink data is generated in a wireless communication terminal to which an uplink resource has not yet been allocated the terminal uses an individual scheduling request resource on a second cell of a smaller cell coverage than a first cell to transmit a scheduling request and in the event that an uplink resource fails to be allocated in response to the scheduling request transmits a random access preamble and carries out a random access procedure requesting a wireless communication device to allocate an uplink resource.

Abstract: Provided is a terminal device with which hybrid automatic repeat request (HARQ) coding gain for all downlink (DL) HARQ processes can be achieved, even if uplink-DL configurations differ among a plurality of unit bands. In this device, a decoder (210) stores, in a retransmission buffer, downlink data transmitted using each of a plurality of unit bands, and decodes the downlink data, and a wireless transmitter (222) uses a first unit band among the plurality of unit bands to transmit a response signal for first downlink data received using the first unit band, and a response signal for second downlink data received using a second unit band. A second buffer for storing second downlink data is partitioned into regions for each retransmission process on the basis of a specific value determined using a combination of a first configuration pattern set for the first unit band, and a second configuration pattern set for the second unit band.

Abstract: Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band, and the terminal device is capable of providing a retransmission control method. In this device, at the time of channel selection, a control unit (208) selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station (100) and PUCCH resources mapped to a CCE, and controls the transmission of the response signal. A response signal generating unit (212) supports implicit signaling with respect to any given response signal, and at the same time as supporting LTE fallback from 2CC, uses a mapping method that, between bits, smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

Abstract: La presente invención pertenece a un aparato de terminal, el cual, cuando ARQ se usa para comunicación que usa una banda de unidad de enlace ascendente y una pluralidad de bandas de unidad de enlace descendente asociadas con la banda de unidad de enlace ascendente, y cuando un modo de transmisión que soporta hasta 2 TB en un PCell se establece en la terminal, es capaz de reducir la cantidad de señalización de una estación base mientras que elimina una falta de recursos PUCCH cuando la planificación semi-persistente (SPS) se usa en el PCe11. Una unidad de control (208) en este aparato selecciona un valor entre valores obtenidos al agregar 1 hasta cuatro índices de recurso PUCCH, que se han pre-establecido para recurso PUCCH 1 por la estación base, en la base de valores para información de control de potencia de transmisión (comando TPC para PUCCH) en un PDCCH, para lo cual la notificación se ha recibido en el inicio de SPS.

Abstract: The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit (208) transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.
