Cell main carrier frequency C0 adopt 51 multi-frames to carry the logic channels such as BCH and CCCH; Particularly, in the TS2/TS4/TS6 of carrier frequency C0, being that in the corresponding time slot of the frame of 0,1,10,11,20,21,30,31,40,41,50, any one or more time slot forms one or more radio block by the frame number in each 51 multi-frames, is a radio block by a time slot mapping.
Map the new radio block obtained and can be used as down control channel, the downlink common control channel such as such as AGCH channel.Utilize this implementation can increase by 11 AGCH Resource Block in each 51 multi-frames.
In superincumbent six kinds of channel mapping modes, be all for AGCH channel, described newly-increased down control channel can also be PCH channel or CBCH channel certainly.
802, base station is to terminal transmitting system message or beep-page message, comprises the instruction of monitoring described down control channel in this system message or beep-page message.
Described down control channel is downlink common control channel newly-increased in step 801.Still for AGCH channel, network side carrys out indicating terminal by system message or beep-page message to be needed to monitor newly-increased AGCH channel, can be in SI2quater, SI3 or other system message, set up one or more bit (bit) carry described indication information particularly.
If the implementation that the free timeslot in the physical channel at the expansion Common Control Channel CCCH place on cell main carrier frequency C0 is mapped as the down control channels such as AGCH by base station is unique, such as only select the one in six kinds of modes cited in above-mentioned steps 801, so can increase a bit in described system message, utilize this bit instruction to have and support that the terminal of described newly-increased down control channel ability removes AGCH channel newly-increased on the CCCH channel of monitor terminal place.
If the process that the free timeslot in the physical channel at the expansion Common Control Channel CCCH place on cell main carrier frequency C0 is mapped as the down control channels such as AGCH is taken two kinds or two or more implementations by base station, so just need in described system message, increase multiple bit and be used as indicating bit.Utilize this indicating bit not only can notify to have and support that the terminal of described newly-increased down control channel ability to remove on the CCCH channel of monitor terminal place newly-increased AGCH channel, but also the mapping mode that AGCH channel newly-increased described in described terminal can be indicated to adopt, in described system message, namely also include the information of the mapping mode indicating described down control channel.
Have and support that the terminal of newly-increased AGCH channel capacity is receiving described system message, then, after have sent access request message to base station, except monitoring existing all PCH channels and special AGCH channel, also can monitor above-mentioned newly-increased AGCH channel.
