As shown in Figure 1, in the embodiment of the present invention one to the indicating means step schematic diagram of E-RUCCH channel, as can be seen from the figure said method comprising the steps of:
Step 101:RNC from terminal can carrier wave select at least one carrier wave.
RNC selects the mode of carrier wave can have multiple, such as: when resource occupation amount is less, can select whole available carrier wave of terminal; Or, according to performance or the channel condition of terminal, from the available carrier wave of terminal, select at least one carrier wave.
Step 102:RNC is described terminal distribution E-RUCCH channel in the carrier wave selected.
RNC can be described terminal distribution E-RUCCH channel in the carrier wave of each selection.
RNC is that terminal distribution E-RUCCH channel comprises: be the control information in terminal configuration E-RUCCH channel and physical resource indication information.It is one or more that one of them control information can comprise in following parameter: E-RUCCH timer (T-RUCCH), E-RUCCH counter (N-RUCCH), scheduling waiting timer (T-WAIT), scheduling activation period timer (T-SI), expansion detection window (ExtendedEstimationWindow), E-RUCCH access service grade (E-RUCCHAccessServiceclass), the E-RUCCH persistence probability factor (E-RUCCHpersistencescalingfactorlist), it is one or more that physical resource indication information can comprise in following parameter: multi-upstream access code information (SYNC_ULinfo), Physical Random Access Channel information (PRACHInformation).
Step 103:RNC determines the carrier identification of each carrier wave at the E-RUCCH channel place of described terminal.
In the present embodiment, RNC can be one or more terminal distribution channels simultaneously, such as: RNC can determine the available carrier wave of terminal A and terminal B respectively, and for terminal A configures E-RUCCH channel in the available carrier wave of terminal A, for terminal B configures E-RUCCH channel in the available carrier wave of terminal B.
The carrier identification of all carrier waves at the E-RUCCH channel place of the just each terminal of step 104:RNC sends to corresponding terminal.
In this step, carrier identification is sent to the corresponding relation simultaneously also sending the channel of the configuration in each carrier identification carrier wave corresponding with this mark during corresponding terminal to terminal by RNC, and what configure in the carrier wave that the carrier identification that notification terminal receives is corresponding is E-RUCCH channel.Such as: RNC selects two carrier waves from the available carrier wave of terminal A, mark is respectively carrier wave 1 and carrier wave 2.The E-RUCCH channel of RNC difference configurating terminal A in two carrier waves, when then carrier wave 1 and carrier wave 2 are sent to terminal A as carrier identification by RNC, the corresponding relation notification terminal A of channel that simultaneously can also will configure in carrier wave and carrier wave, corresponding relation is here: be configured with an E-RUCCH channel in the carrier wave of carrier wave 1 correspondence; An E-RUCCH channel is configured with in the carrier wave of carrier wave 2 correspondence.Terminal receives the corresponding relation of the channel of carrier identification and carrier identification and configuration, and after determining corresponding carrier wave according to the carrier identification received, can know in the carrier wave determined to have E-RUCCH channel.
