一种无线通信系统包括用于在不同时隙与相应移动台(MS)通信的共享TDM数据信道以及专用信道。在基站控制器中提供的第一媒体接入控制(MAC)复用子层把通信业务的逻辑信道的信息映射到通信信道。第二MAC复用子层把在第一MAC复用子层中映射到共享数据信道的信息映射到在共享信道的相应TDM时隙中传递的相应数据单元。第二MAC复用子层处理共享数据信道以及共享数据信道的共享控制信道、来自MS的信道质量反馈和数据确认信道上的信息的调度、自适应调制和编码以及自动重传。 A wireless communications system includes a shared TDM data channel for communications in different time slots with respective mobile stations (MSs), as well as dedicated channels. A first medium access control (MAC) multiplexing sublayer, provided in a base station controller, maps information of logical channels for communications services to the communications channels. A second MAC multiplexing sublayer maps information, mapped to the shared data channel in the first MAC multiplexing sublayer, to respective data units for communication in respective TDM time slots of the shared channel. The second MAC multiplexing sublayer handles scheduling, adaptive modulation and coding, and automatic retransmission of information on the shared data channel, as well as shared control channels for the shared data channel and channel quality feedback and data acknowledgement channels from the MSs.
