Abstract:
A PUCCH resource collision between a normal mode terminal and MTC coverage enhancement mode terminal is avoided. A terminal includes a receiving section that receives control information indicating assignment of downlink data, and the downlink data; and a transmitting section that transmits a response signal using a resource in a first resource group when the terminal is a first terminal to which repetition transmission is applied, and that transmits the response signal using a resource in a second resource group that is different from the first resource group, when the terminal is a second terminal to which the repetition transmission is not applied.
Abstract:
Provided are wireless communication methods, an eNB and a UE. The wireless communication method performed by an eNB comprises transmitting downlink control information (DCI) to a user equipment (UE), wherein the DCI is designed based on a coverage enhancement level for the UE.
Abstract:
Se proporcionan dispositivos y métodos de comunicación inalámbrica. En una realización, un método de comunicación inalámbrica realizado por un dispositivo de comunicación inalámbrica comprende una etapa de transmitir un paquete de datos repetidamente en múltiples submarcos que incluyen por lo menos un submarco normal y por lo menos un submarco especial a otro dispositivo de comunicación inalámbrica, en el que los recursos disponibles en el submarco especial son diferentes de aquellos en el submarco normal, el paquete de datos incluye múltiples símbolos modulados que se dividen en múltiples grupos de símbolos modulados, en cada submarco, cada símbolo OFDM se mapea por uno de los grupos de símbolos modulados, y en cada submarco, los símbolos modulados en el mismo grupo de símbolos modulados se mapean en el RE en un símbolo OFDM en un orden fijo. En otra realización, se transmiten múltiples repeticiones del paquete de datos en cada submarco, y en cada submarco especial, se mapean diferentes repeticiones en el RE con cambio cíclico.
Abstract:
Provided are wireless communication methods and devices. In one embodiment, a wireless communication method performed by a wireless communication device comprises a step of transmitting a data packet repeatedly in multiple subframes including at least one normal subframe and at least one special subframe to another wireless communication device, wherein the available resources in the special subframe are different from that in the normal subframe, the data packet includes multiple modulated symbols which are divided into multiple modulated-symbol sets, in each subframe, each OFDM symbol is mapped by one of the modulated-symbol sets, and in every subframe, the modulated symbols in the same modulated-symbol set are mapped onto REs in one OFDM symbol in a fixed order. In another embodiment, multiple repetitions of the data packet are transmitted in each subframe, and in each special subframe, different repetitions are mapped onto REs with cyclic shift.
