Here we will mention some of the terminology, these terms will be related in the back will be described in detail; To their message heard on the HS-SCCH, the user can then immediately go to the HS-PDSCH (High Speed ??Physical Downlink Shared Channel) downlink channel used to send data, receive data. Next, the user reuse the uplink HS-DPCCH (High Speed ??Dedicated Physical Control Channel) send ACK / NACK and rewards of network quality CQI (Channel Quality Indicator) to the network. The laptop battery network return CQI decided the next time you give the user the amount of data and the modulation scheme. It is noteworthy that these downstream channel we mentioned above, whether it is used to notify the HS-SCCH or HS-PDSCH is used to send data channels are shared by all users. Multiple users listening to the same HS-SCCH all users take turns using the whole cell limited (up to 15) the HS-DPSCH send information. Node B is responsible for the scheduling of these channels, where the periods, where some HS-PDSCH specify where users use.These involve very complex judgments, including each phone returns the CQI, its highest rate supported by each user's priority ... to consider. Figure 2 is a possible schedule. In this example, the Node B based on its internal algorithm, these resources, that is, channels, not only the use of time division multiple tasks, and these channels are allocated to each user by the code division multiple tasks. Other feasible way of scheduling, like the order cycle (in other words, the only time-sharing, multi-task scheduling) to send data to those with higher priority users, as well as reference returns CQI schedule. Users, in each time period, he may be assigned or given one or several channels, to accept the network to send over the data. The design of this laptop battery, you can quickly change the schedule to switch and control the amount of data transferred for each user, so as to avoid the front we have mentioned some of the limitations of the transmission Release 99 CELL_DCH.
