    • Techniques for sending hybrid automatic repeat request (HARQ) feedback for stransmissions received via a plurality of aggregated component carriers are disclosed. A wireless transmit/receive unit (WTRU) receive a plurality of codewords via a plurality of component carriers and decodes the codewords. The component carriers are grouped into a plurality of groups, and the WTRU may generate a bundled positive/negative acknowledgement (ACK/NACK) for each group of component carriers. The WTRU may be assigned a plurality of uplink control channel resources and may implement a channel selection scheme for indicating the ACK/NACKs. The WTRU selects one of the uplink control channel resources, and sets the HARQ feedback based the ACK/NACKs or bundled ACK/NACKs in a way that a different uplink control channel resource is selected and HARQ feedback bits are set differently based on the ACK/NACKs or bundled ACK/NACKs. Each physical uplink control channel (PUCCHs) may be mapped to a particular antenna.
    • 公开了用于发送经由多个聚合分量载波接收的发送的混合自动重传请求(HARQ)反馈的技术。 无线发射/接收单元(WTRU)经由多个分量载波接收多个码字并解码码字。 分量载波被分组成多个组,并且WTRU可以为每组分量载波生成捆绑的肯定/否定确认(ACK / NACK)。 WTRU可以被分配多个上行链路控制信道资源,并且可以实现用于指示ACK / NACK的信道选择方案。 WTRU选择上行链路控制信道资源中的一个,并且以不同的上行链路控制信道资源被选择的方式基于ACK / NACK或绑定的ACK / NACK来设置HARQ反馈,并且HARQ反馈比特被不同地基于ACK / NACK或捆绑的ACK / NACK。 每个物理上行链路控制信道(PUCCH)可以映射到特定的天线。
