Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

Among the present invention, NodeB is when carrying out resource allocation, and at first allocation algorithm resource on the upstream hardware of R99 type is set up UL DPCCH channel and UL DPDCH channel then on the algorithm resource of distributing; After this, NodeB is the allocation algorithm resource on the upstream hardware of R5 type, is replicated in the UL DPCCH channel of setting up on the R99 type algorithm resource, sets up the HS-DpCCH channel according to this UL DPCCH channel then.

Below specific embodiments of the invention are described.

In the present embodiment, the upgrading base station of R99 type during to the base station of R5 type, is partly being kept the upstream hardware of original R99 type in the Base-Band Processing of base station, and increasing the upstream hardware of R5 type.Fig. 2 is for comprising the base station baseband processing section hardware resource schematic diagram of R99 type upstream hardware and R5 type upstream hardware simultaneously, wherein 201 is the Base-Band Processing part of NodeB, 202 and 203 is the upstream hardware of R99 type, 204 and 205 is the upstream hardware of R5 type, each hardware has certain last line algorithm resource, dash area is wherein represented used up algorithm resource, blank parts representative residue algorithm resource.

After the upstream hardware that has increased the R5 type, in Radio Link foundation or wireless links reconfiguration course, when needing NodeB to carry out resource allocation, RNC sends Radio Link to NodeB and sets up or the radio link reconfiguration signaling, is included as the information which kind of business is carried out resource allocation in the signaling.

NodeB receive that the Radio Link that comprises HSDPA information is set up or the signaling of radio link reconfiguration after, the process of carrying out resource allocation and setting up channel as shown in Figure 3, concrete steps are as follows:

Whether comprise HSDPA information in Radio Link foundation that step 301, NodeB judgement receive or the radio link reconfiguration message, if comprise these information, execution in step 302; Otherwise, execution in step 308.The HSDPA information spinner here will comprise high speed descending sharing channel information (High SpeedDownlink Shared Channel Information, HS-DSCH Information), high speed descending sharing channel Radio Network Temporary Identifier (HS-DSCH Radio Network TemporaryIdentity, HS-DSCH-RNTI) and high speed down sharing physical channel Radio Link sign (HighSpeed Physical Shared Channel Radio Link Identity, HS-PDSCH RL ID).

Step 302, NodeB detect the upstream hardware of Base-Band Processing part, search the maximum upstream hardware of residue algorithm resource.

The last line algorithm resource of one group of upstream hardware formation has certain processing capabilities, holds the business of some different bandwidths etc. as the last line algorithm resource fork of one group of upstream hardware formation.To go up the line algorithm resource division in the present embodiment is counting of given number, and Resources allocation is exactly to consume counting on the algorithm resource.Resources allocation consumed count according to spreading factor (Spread Frequency SF) calculates, and the method that the calculating of simplification is counted equals 32 divided by SF for counting of consuming, but when SF greater than 32 the time, for avoiding the appearance of decimal, calculate with 32.For example when spreading factor is 32,64,128 or 256, counting of being consumed is a point, and when spreading factor was 4, counting of being consumed just was 8 points, after carrying out resource allocation on the last line algorithm resource, NodeB can write down the consumption situation that wherein goes up the line algorithm resource.In this step, NodeB detects the consumption situation of last line algorithm resource, how much comes to determine the surplus resources situation according to what residue on the last line algorithm resource was counted, remains maximum last line algorithm resource of counting and is the maximum last line algorithm resource of surplus resources.Under situation as shown in Figure 2, the maximum hardware of residue algorithm resource is 203, is the upstream hardware of R99 type.

Step 303, NodeB judge whether the maximum upstream hardware of selected residue algorithm resource is the R5 type, if the R5 type, execution in step 304; Otherwise this upstream hardware is the R99 type, execution in step 305.

Here, the judgement of upstream hardware type is carried out according to the hardware version information of storing among the NodeB.When increasing on the R5 type line algorithm resource for NodeB, can be in NodeB the version information of line algorithm resource on the version information of line algorithm resource and the newly-increased R5 type on the original R99 type of storage.

Step 304, on the upstream hardware of the R5 type that finds out the allocation algorithm resource, on the algorithm resource of distributing, set up UL DPCCH channel and UL DPDCH channel then, set up the HS-DPCCH channel according to ULDPCCH channel and timing relationship again.

In this step, when Resources allocation, for the algorithm resource of its distribution is determined according to spreading factor.Setting up channel in fact is exactly to obtain the information that this channel comprises from the signal that the base station received, the information that obtains to comprise in this channel just needs the base station to carry out despreading to received signal, separate and be in harmonious proportion processing such as CRC check, and the allocation algorithm resource is distributed exactly and carried out these processing resource needed on last line algorithm resource.In addition, because information obtains in the HS-DPCCH channel, need to rely on the information such as uplink scrambling code, minimum channel code length, vertical shift, sign indicating number skew and propagation delay in the UL DPCCH channel, so the foundation of HS-DPCCH channel lags behind the regular hour than UL DPCCH channel, that is to say that both need certain timing relationship.

Step 305, NodeB allocation algorithm resource on the R99 type upstream hardware that finds out, and on the algorithm resource of distributing, set up UL DPCCH channel and UL DPDCH channel, execution in step 305 then.In this step, the size of the algorithm resource of distribution is determined according to spreading factor.As shown in Figure 4,401 be the algorithm resource of on line algorithm resource on the R99 type, distributing.

Step 306, NodeB detect the last line algorithm resource of the R5 type of Base-Band Processing part, therefrom select the maximum hardware of surplus resources, then allocation algorithm resource on this hardware.Here, because the algorithm resource of distributing is used to set up the HS-DPCCH channel, and the spreading factor of HS-DPCCH channel is fixed as 256, so the resource of being distributed is 1 point.Under the situation of Fig. 2, the hardware of the R5 type that residue algorithm resource is maximum is 204, and then accordingly in Fig. 4, the algorithm resource of distributing on line algorithm resource on this R5 type is 402.

Step 307, NodeB are replicated in the UL DPCCH channel of setting up on the R99 type algorithm resource, channel after duplicating is called follows UL DPCCH channel, follows UL DPCCH channel to set up the HS-DPCCH channel with certain timing relationship on the R5 type algorithm resource of distributing according to this then.

Described in step 304, the foundation of HS-DPCCH channel will be carried out with certain timing relationship according to UL DPCCH channel, so need earlier the UL DPCCH duplicating channel on the R99 type algorithm resource to be come, can set up the HS-DPCCH channel according to information wherein then, owing on R99 type algorithm resource, set up UL DPCCH channel, followed UL DPCCH channel so this UL DPCCH channel that duplicates is called.Duplicate UL DPCCH channel, the last line algorithm resource that is actually the R5 type is obtained from the signal that the base station received and is set up HS-DPCCH channel parameters needed, parameter in the UL DPCCH channel that these parameters Resources allocation on the R99 type upstream hardware is set up is identical, so be referred to as to duplicate the UL DPCCH channel on the R99 type algorithm resource, after having obtained these parameters, set up the HS-DPCCH channel according to these parameters and timing relationship, HS-DPCCH channel after the foundation is finished to mix in the HSDPA function and is retransmitted (HybridAcknowledgement automatically, HARQ) and channel quality measurement report (Channel Quality Indication, CQI) collection of information, so there is not transmission channel corresponding with it, when the Radio Link ascender transmits, be called virtual uplink physical channel at it.

Be illustrated in figure 5 as the channel schematic diagram of on the algorithm resource of distributing, setting up in step 305 and the step 307, wherein, 501 is the upstream hardware of R99 type, 502 is the last line algorithm resource of R5 type, 503 is the algorithm resource of distributing on the upstream hardware of R99 type, 504 is UL DPCCH channel and the UL DPDCH channel of setting up on the algorithm resource of distributing, 505 is the algorithm resource of distributing on the upstream hardware of R5 type, 506 is the HS-DPCCH channel of setting up on the algorithm resource 505 of distributing, 507 is the Radio Link ascender, be converted into transmission channel by Radio Link ascender uplink physical channel and send upper strata among the NodeB then to, 508 is the uplink physical channel that UL DPCCH and UL DPDCH transmit to the Radio Link ascender, because it is corresponding with it that the HS-DPCCH channel does not have transmission channel on the upper strata of NodeB, so 509 is virtual uplink physical channel.

Step 308, NodeB detect upstream hardware wherein, search and wherein remain the maximum hardware of algorithm resource, allocation algorithm resource on the maximum upstream hardware of the residue algorithm resource that finds then, and on the algorithm resource of distributing, set up UL DPCCH channel and UL DPDCH channel.

From above explanation to the specific embodiment of the invention as can be seen, among the present invention,, on the algorithm resource of distributing, set up ULDPCCH channel and UL DPDCH channel then by allocation algorithm resource in the R99 of base station type upstream hardware; After this, allocation algorithm resource in the upstream hardware of R5 type, duplicate the UL DPCCH channel on the R99 type algorithm resource then, set up the HS-DPCCH channel according to the ULDPCCH channel that duplicates again, when realizing the HSDPA business, utilized the upstream hardware of R99 type, avoided waste R99 type of hardware resource; In addition, the present invention is by Resources allocation on the maximum upstream hardware of residue algorithm resource, and resource allocation methods is more reasonable; And then, the present invention is by when the maximum hardware of surplus resources is the hardware of R5 type, directly distribute ULDPCCH channel, UL DPDCH channel and HS-DPCCH channel thereon, avoided further having increased the rationalization of resource allocation having consumed Resources allocation on the R99 type upstream hardware of a lot of algorithm resources.

In concrete implementation process, can carry out suitable improvement, to adapt to the concrete needs of concrete condition to the method according to this invention.Therefore be appreciated that according to the specific embodiment of the present invention just to play an exemplary role, not in order to restriction protection scope of the present invention.
