Description

Channel resource allocation method

Technical field

The present invention relates to the CDMA communication technology, in particular, the present invention relates to a kind of channel resource allocation method in TD SDMA (TD-SCDMA, Time Division-Synchronization Code DivisionMultiple 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, InternationalTelecommunication 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 mobile communication system, in order to satisfy the ever-increasing demand in mobile communication 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 to add the mode of several minor carriers, promptly only on a carrier frequency of cell/section, send pilot tone and broadcast message, other carrier frequency is as minor carrier, sub-district must have one and have only a main carrier, a plurality of frequencies use a common broadcasting, and its detailed protocol is as follows:

At each sector, from n the frequency that is assigned to, determine one as main carrier, in same sector, only on main carrier, send DwPTS and broadcast message (TS0).When setting up the sub-district, need clearly indicate main carrier, so that Node B determines to send broadcasting on which frequency, and in the message of channel configuration, need to increase frequency point information, so that terminal and Node B obtain related content.

Prior art is only distributed common signal channel at main carrier during allocation of channel resources may in above-mentioned multicarrier system, then the free time need not for the TS0 on the auxilliary carrier wave; Promptly only allow to use the TS1～TS6 on the auxilliary 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%, capacitance loss on the also promptly auxilliary carrier wave is 19%, in existing overloading frequency scheme, only there is a main carrier in a sub-district, and has a plurality of auxilliary carrier waves, capacitance loss on auxilliary carrier wave reaches 19%, and this is difficult to tolerate.

In addition, because UpPCH, FPACH only are configured on the main carrier, also there is following shortcoming in prior art:

1, subscriber equipment (UE, User Equipment) can not support overloading UE frequently to be configured to auxilliary carrier wave when other sub-district switches to this sub-district.

Because UE has carried out the minizone switching, need be UE collocating uplink synchronization parameter.If UE does not support overloading frequently,, this UE can not be configured on the auxilliary carrier wave, and can only refuse this UE even then the auxilliary carrier wave of this sub-district has resource.This is because if radio network controller (RNC, Radio Network Controller) is configured to auxilliary carrier wave with this UE, because UE does not support overloading frequently, can only dispose a frequency point information among the frequency information Frequency Info.For UE,, in the time of need carrying out uplink synchronous, can only on the frequency (promptly auxilliary carrier wave) of RNC configuration, carry out because this UE does not support overloading frequently.RNC is configured to UE on the auxilliary carrier wave, and does not have corresponding physical access channel (FPACH, Fast Physical AccessChannel) on the auxilliary carrier wave, therefore, UE can not can not get the response of NodeB after sending the Sync_UL sign indicating number on the auxilliary carrier wave, must cause the uplink synchronous failure.

2, UE switches to this sub-district from other sub-district, the main carrier inadequate resource of this sub-district, when auxilliary carrier wave has resource, very easily causes the congested of main carrier, has weakened overloading advantage frequently greatly.

Since when UE when other sub-district switches to this sub-district, can not will not support overloading UE frequently to be configured to auxilliary carrier wave, the consequence that causes thus is: for not supporting overloading UE frequently, even the auxilliary carrier wave of this sub-district have resource, as long as the main carrier inadequate resource of this sub-district also UE can only be refused.

In handoff procedure, can only very easily cause the congested of main carrier with not supporting overloading UE frequently to be configured on the main carrier, weakened overloading advantage frequently greatly.

But in the current generation, most of UE can't support overloading frequently, and the multicarrier advantage can't be brought into play.

3, in processes such as switching, UE is assigned to auxilliary carrier wave and need carries out the operation of open loop uplink synchronous, even for supporting overloading UE frequently, when UE is assigned to auxilliary carrier wave, cause easily makeing mistakes.

In processes such as switching, if UE is assigned to auxilliary carrier wave and need carries out the operation of open loop uplink synchronous, then be to comprise up DPCH sign indicating number 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 auxilliary 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 sign indicating number information, uplink synchronous parameter in the up DPCH information be resolved to respectively: the up DPCH sign indicating number information on the auxilliary carrier wave, the uplink synchronous parameter on the main carrier.This is unallowed, is easy to cause makeing mistakes.

Need to prove, be that Node B must detect corresponding UpPCH channel (being the Sync_UL sign indicating number) after auxilliary carrier wave had disposed the FPACH channel.

With reference to figure 3, this figure is that Common transport channel of the present invention is set up process.

The present invention sets up in the process in the sub-district, the process of setting up for the Common transport channel of main carrier (being main carrier frequency), do not change, for auxilliary carrier wave, common signal channel only need dispose the FPACH channel, and does not dispose other common signal channels such as P-CCPCH, S-CCPCH (FACH, PCH, PICH), PRACH.If the FPACH channel is not carried out wave beam forming, can not dispose the FPACH channel on the then auxilliary carrier wave.

Here the FPACH channel being carried out wave beam forming, is in order to make that the behavior of FPACH channel is similar to DPCH on auxilliary carrier wave, to cover and need not to carry out full sub-district.The benefit that can bring is as follows thus:

In auxilliary carrier wave inside, owing to there is not omnidirectional's down channel, FPACH channel and DPCH interchannel can not produce serious disturbance; The behavior of system on auxilliary carrier wave is similar to a bearer service channels, and be compatible fully with current overloading frequency scheme; Even FPACH is disposed on the TS0 of auxilliary carrier wave, can not produce serious the interference with the common signal channel on the main carrier yet.

Describe FPACH channel of the present invention below in detail and set up process.

Also please refer to Fig. 3, the FPACH channel is set up the process configuration by the Common transport channel of Iub interface, mainly may further comprise the steps:

When auxilliary carrier wave was set up the FPACH channel, RNC sent the Common transport channel that comprises described newly-increased auxilliary carrier wave FPACH channel information content to Node B and sets up request message;

Node B sets up the FPACH information content of request message and sets up the FPACH channel at auxilliary carrier wave according to the Common transport channel of described expansion, monitor the UpPCH channel, and return Common transport channel to RNC and set up response message.

Wherein, the Common transport channel on the auxilliary carrier wave is set up process and can be repeated repeatedly as required.

After sub-district foundation is finished, in system information broadcast subsequently, only broadcast the common signal channel configuration information on the main carrier.

In processes such as switching, if UE is assigned to auxilliary carrier wave and need carries out the operation of open loop uplink synchronous, then can directly inform UE by signaling message with the FPACH information on the auxilliary carrier wave in this sub-district, and the mode by system information broadcast not.For example described signaling message comprises that radio resource control information RRC is (as physical channel reconfiguration message Physical Channel Reconfiguration, cell update acknowledgement message CELL UPDATE CONFIRM, instruction switches to UTRAN message HANDOVER TOUTRAN COMMAND, radio bearer reconfiguration message RADIO BEARERRECONFIGURATION, radio bearer release message RADIO BEARER RELEASE, radio bearer is set up message RADIO BEARER SETUP, message RRCCONNECTION SETUP is set up in the RRC connection, transmission channel reconfiguration message TRANSPORT CHANNELRECONFIGURATION) the up DPCH information in.
