Description
Technical field
The present invention relates to the CDMA communication technology, in particular, the present invention relates to a kind of channel establishing method in TD SDMA (TD-SCDMA, Time Division-Synchronization Code Division Multiple Access) multicarrier system.
Background technology
At present, mobile communication has developed into 3G (Third Generation) Moblie (3G, Third Generation). One of three main standard of the TD-SCDMA 3G (Third Generation) Moblie that to be in May, 2000 approved by 3GPP by International Telecommunications Union (ITU, International Telecommunication Union), March calendar year 2001. As the 3G standard of time division multiplexing mode, TD-SCDMA is used as the time-division multiplex technology scheme of low spreading rate (1.28MCps, 1.28 million chips/sec) in the ITU standard.
The same with other GSM, in order to satisfy the ever-increasing demand of Mobile Communications Market, the TD-SCDMA system also need adopt and carry out the mode that multicarrier covers in same sectors/cells and increase power system capacity.
For realizing that multicarrier covers, prior art adopts a main carrier frequency to add the mode of several minor carriers, namely only send pilot tone and broadcast message at carrier frequency of cell/section, other carrier frequency is as minor carrier, residential quarter must have one and only have a main carrier frequency, a plurality of frequencies use a common broadcasting, and its detailed protocol is as follows:
For each sector, from n the frequency that is assigned to, determine one as main carrier frequency, in same sector, only send DwPTS and broadcast message (TS0) at main carrier frequency. When setting up the residential quarter, need to clearly indicate main carrier frequency, so that Node B determines which frequency to send broadcasting in, and in the message of channel configuration, need to increase frequency point information, so that terminal and Node B obtain related content.
Because ascending pilot channel UpPCH, physical access channel FPACH only are configured on the main carrier frequency, there is following shortcoming in prior art:
1, subscriber equipment (UE, User Equipment) can not be configured to the UE that does not support multi-carrier frequency auxiliary carrier wave when switching to this residential quarter from other residential quarter.
Because UE has carried out the minizone switching, need to be UE collocating uplink synchronization parameter. If UE does not support multi-carrier frequency, even then the auxiliary carrier wave of this residential quarter has resource, this UE can not be configured on the auxiliary carrier wave, and can only refuse this UE. This is because if radio network controller (RNC, Radio Network Controller) is configured to auxiliary carrier wave with this UE, because UE does not support multi-carrier frequency, can only dispose a frequency point information among the frequency information Frequency Info. For UE, because this UE does not support multi-carrier frequency, in the time of need carrying out uplink synchronous, can only carry out at the frequency (being auxiliary carrier wave) of RNC configuration. RNC is configured to UE on the auxiliary carrier wave, and there is not corresponding physical access channel (FPACH on the auxiliary carrier wave, Fast Physical Access Channel), therefore, UE is after auxiliary carrier wave sends the Sync_UL code, the response of NodeB can not be can not get, the uplink synchronous failure must be caused.
2, UE switches to this residential quarter from other residential quarter, the main carrier inadequate resource of this residential quarter, when auxiliary carrier wave has resource, very easily causes the congested of main carrier, has greatly weakened the advantage of multi-carrier frequency.
Because when UE switches to this residential quarter from other residential quarter, the UE that does not support multi-carrier frequency can not be configured to auxiliary carrier wave, the consequence that causes thus is: for the UE that does not support multi-carrier frequency, even the auxiliary carrier wave of this residential quarter have resource, as long as the main carrier inadequate resource of this residential quarter also UE can only be refused.
In handoff procedure, the UE that does not support multi-carrier frequency can only be configured on the main carrier, very easily cause the congested of main carrier, greatly weakened the advantage of multi-carrier frequency.
But in the current generation, most of UE can't support multi-carrier frequency, and the multicarrier advantage can't be brought into play.
3, in the processes such as switching, UE is assigned to auxiliary carrier wave and need to carries out the operation of open loop uplink synchronous, even for the UE that supports multi-carrier frequency, when UE is assigned to auxiliary carrier wave, cause easily makeing mistakes.
In the processes such as switching, if UE is assigned to auxiliary carrier wave and need to carries out the operation of open loop uplink synchronous, then be to comprise up DPCH code information and uplink synchronous parameter in uplink special physical channel (DPCH, the Dedicated Physical Channel) information of UE appointment.
The uplink synchronous parameter comprises UpPCH channel, the FPACH channel that allows UE to use. Owing on auxiliary carrier wave, do not allow to use UpPCH channel, FPACH channel, therefore, can only be the uplink synchronous information on the main carrier with the uplink synchronous information analysis, that is: up DPCH code information, uplink synchronous parameter in the up DPCH information be resolved to respectively: the up DPCH code information on the auxiliary carrier wave, the uplink synchronous parameter on the main carrier. This is unallowed, is easy to cause makeing mistakes.
In addition, prior art is only distributed common signal channel at main carrier during allocation of channel resources may in above-mentioned multicarrier system, and then the free time need not for the TS0 on the auxiliary carrier wave; Namely only allow to use the TS1～TS6 on the auxiliary carrier wave, TS0, special time slot (comprising DwPTS, GP, UpPTS) are on the shelf.
Because the length of a subframe is that (length of each time slot is 864Chip to 6400Chip, totally 7 time slots; The special time slot total length is 352Chip, so the total length of a subframe is 7*864+352=6400);
Length available is TS1～TS6, be total to 6*864Chip, so the power system capacity utilization rate is 81%, also be that capacitance loss on the auxiliary carrier wave is 19%, in existing multi-carrier frequency scheme, only there is a main carrier in a residential quarter, and has a plurality of auxiliary carrier waves, capacitance loss on auxiliary carrier wave reaches 19%, and this is difficult to tolerate.
Summary of the invention
