    • Methods described herein are for wireless communication systems. One aspect of the invention is directed to a method for a HARQ process, in which the HARQ process includes a first transmission of an encoder packet and at least one retransmission. The method involves allocating a transmission resource for each respective transmission. The method involves transmitting control information from a base station to a mobile station for each respective transmission. The control information includes information to uniquely identify the HARQ process and an identification of one of a time resource, a frequency resource and a time and frequency resource that is allocated for the transmission. In some embodiments of the invention, specific control information is signalled from a base station to a mobile station to enable RAS-HARQ operation. In some embodiments of the invention, retransmission signaling in included as part of regular unicast signaling used for both first transmission and retransmissions. In some embodiments of the invention, a 3-state acknowledgement channel and associated error recovery operation enables the base station and mobile station to recover from control signaling error and reduce packet loss.
    • 本文描述的方法用于无线通信系统。 本发明的一个方面涉及一种用于HARQ过程的方法,其中所述HARQ过程包括编码器分组的第一传输和至少一个重传。 该方法包括为每个相应的传输分配传输资源。 该方法涉及从每个相应传输的基站向移动台发送控制信息。 控制信息包括用于唯一地识别HARQ过程的信息和为传输分配的时间资源,频率资源和时间和频率资源之一的标识。 在本发明的一些实施例中,从基站向移动台发信号通知特定的控制信息以启用RAS-HARQ操作。 在本发明的一些实施例中,包括作为用于第一传输和重传的常规单播信令的一部分的重传信令。 在本发明的一些实施例中,3状态确认信道和相关联的错误恢复操作使得基站和移动台能够从控制信令错误中恢复并减少分组丢失。
