Two different types of signaling channels are used to communicate signaling information to a user equipment terminal in a radio communications system. A first type of signaling channel is dedicated for each of multiple user equipment terminals to transmit minimal notification information. A shared signaling channel is established between a radio access network and the multiple user equipment terminals to transmit substantive signaling information relevant to a data channel. Each of the multiple user equipment terminals is notified via its dedicated signaling channel when information on the shared signaling channel is relevant to that user equipment terminal. For example, the dedicated signaling channel may provide a power on/off type of notification to the user equipment. When an "on" signal is detected, the user equipment terminal receives and detects the information on the shared signaling channel, and using that information, receives and detects data packets on the data channel. Otherwise, the user equipment terminal does not waste resources monitoring or receiving information on the shared signaling channel. Alternatively, a single bit flag my sent to provide a positive or negative notification. The signaling information may include any type of control information. In a non-limiting, example, embodiment, the signaling information includes one or more parameters relating to transmission of data over the data traffic channel such as a modulation scheme, a coding scheme, data packet sequence numbering information, spreading code information, timing information, etc. |
