Abstract
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.
