    Abstract: A method whereby a user equipment (UE) transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) information corresponding to downlink data received from a corresponding base station (ENB) in a long term evolution-advanced (LTE-A) system supporting carrier aggregation (CA) is provided. When physical uplink shared channel (PUSCH) transmission is not scheduled at the time of transmission of HARQ ACK/NACK information, the UE transmits HARQ ACK/NACK information via physical uplink control channel (PUCCH). When PUSCH transmission is scheduled, the UE transmits HARQ ACK/NACK information multiplexed with PUSCH to the ENB. The amount of HARQ ACK/NACK information increases in proportion to the number of aggregated carriers. The present disclosure specifies scheduling operation of the ENB and HARQ ACK/NACK mapping of the UE that maintain reception performance of HARQ ACK/NACK and PUSCH when HARQ ACK/NACK information is multiplexed with PUSCH.

    Abstract translation: 一种用户设备（UE）在长期进化高级（LTE）中发送与从对应的基站（ENB）接收的下行链路数据相对应的混合自动重传请求（HARQ）确认（ACK）/否定ACK（NACK）信息的方法 -A）提供系统支持载体聚合（CA）。 在发送HARQ ACK / NACK信息时不调度物理上行链路共享信道（PUSCH）传输时，UE经由物理上行链路控制信道（PUCCH）发送HARQ ACK / NACK信息。 当PUSCH发送被调度时，UE向PUSCH发送与PUSCH复用的HARQ ACK / NACK信息。 HARQ ACK / NACK信息的量与聚合载波的数量成比例地增加。 本公开规定了当HARQ ACK / NACK信息与PUSCH复用时，维持HARQ ACK / NACK和PUSCH的接收性能的UE的ENB和HARQ ACK / NACK映射的调度操作。
