Abstract: Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.
Abstract translation: 方法和装置利用可在多个载波上使用的混合自动重传请求（HARQ）传输和重传，即联合HARQ过程。 例如，在其中一个载波上接收联合HARQ进程的下行链路（DL）共享信道传输。 联合HARQ过程的身份的第一部分通过使用在共享控制信道上接收的HARQ进程身份数据来确定。 使用附加信息确定联合HARQ过程身份的第二部分。 然后通过组合第一部分和第二部分来确定联合的HARQ进程标识。 提供了一种被配置为接收DL共享信道并进行上述确定的WTRU。 公开了用于利用联合HARQ过程的各种其它方法和装置配置，特别是在DC-HSDPA的上下文中。
