Description
Technical field
The present invention relates to high speed downlink packet and insert (HSDPA) technical field, relate in particular to the method and system of a kind of distribution high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH) sign indicating number.
Background technology
The HSDPA technology is the key property of Wideband Code Division Multiple Access (WCDMA) (WCDMA) network R5 version.The HSDPA technology retransmits application (HARQ), Fast Packet scheduling key technologies such as (FPS) automatically by adaptive modulation and coding (AMC), mixing, has realized the high speed data transfer on the down link.
In the HSDPA technology, the high speed descending sharing channel (HS-DSCH) that switches between the user at interval with 2ms can be provided, in order to realize the HS-DSCH transmission, HSDPA has introduced three new physical channels.Wherein, High-Speed Shared Control Channel (HS-SCCH) and High-Speed Dedicated Physical Control Channel (HS-DPCCH) are used for control, and HS-PDSCH is used to carry the high-speed downstream user data.In the HSDPA technology, every HS-PDSCH has different Orthogonal Variable Spreading Factor OVSF (OVSF) channel code, i.e. channel code, and the quantity of available channel sign indicating number and every channel can the data carried by data amount depend on the spreading factor (SF) of channel.HSDPA standard code HS-PDSCH channel uses the channel code of SF=16, the HS-SCCH channel uses the channel code of SF=128, as shown in Figure 1, Fig. 1 is the schematic diagram of HSDPA ovsf code tree, represent each code channel with dot among Fig. 1, wherein the round dot of black filling is the spendable code channel of HSDPA, and HS-PDSCH can use the code channel of 15 SF=16 as seen from Figure 1.Wherein, every corresponding HS-PDSCH channel code of HS-PDSCH channel, the span of HS-PDSCH channel code is that 1 to 15, one operable HS-PDSCH channel in sub-district can reach 15 at most.
In the WCDMA system, the user utilizes the HSDPA technology to carry out transfer of data: by the HSDPA resource in radio network controller (RNC) the static allocation sub-district is that one group of HS-PDSCH channel code is given base station (Node B), Node B is according to the channel code of RNC indication and ability rating, transfer of data demand and the residing channel circumstance of subscriber equipment (UE), with the HS-PDSCH channel code reasonably dynamic assignment give each UE, make UE can use the HS-PDSCH channel corresponding to carry out high speed data transfer on the down link with the HS-PDSCH channel code of distributing.
As shown in Figure 2, Fig. 2 is the method flow diagram that distributes the HS-PDSCH channel code in the prior art, and this flow process may further comprise the steps:
Step 201 is set up special-purpose HSDPA wireless channel.
Step 202, RNC uses the situation of HS-PDSCH channel code and the situation of using other non-HSDPA channel according to needs in the sub-district, one group of continuous HS-PDSCH channel code of fixed allocation, this channel code character are carried at Physical Shared Channel in application protocol (NBAP) message of Node B and reshuffle and be handed down to Node B in the signaling.Here, described non-HSDPA channel can be a R99 channel etc.
In this step, RNC determines earlier to need to use several HS-PDSCH channel code in the sub-district, one group of continuous HS-PDSCH channel code of fixed allocation then, reshuffle signaling by Physical Shared Channel and indicate B to Node, this group channel code can be again by other channel occupancy, and can not give the user who is carried on the HSDPA use for other the idle channel code beyond this group.
Wherein, RNC determines that needing to use several HS-PDSCH channel code in the sub-district is according to each bar channel in this sub-district the operating position of sign indicating number resource to be determined, need take the channel code of several SF=16 as the R99 channel, the HSDPA channel need take the channel code of several SF=16, the static in advance then channel code with each SF=16 is distributed to various channels. distinguishingly, and for HSDPA distributes zero group HS-PDSCH channel code.
Reshuffle when carrying the channel code character in the signaling at Physical Shared Channel, need the initial code sign indicating number number and the channel code number of this channel code character of record.According to 3GPP TS25.433-5c0 agreement regulation, Physical Shared Channel reshuffles that signaling indicates must be continuously to the HS-PDSCH channel code of Node B, and one group of continuous channel code can only be arranged; 3GPP TS25.433-5c0 agreement has stipulated that also form that Physical Shared Channel reshuffles signaling is as shown in Table 1:
| Cell | Parameter declaration | Span | Parameter type | Remarks |
| HS-PDSCH channel code number | M | 0 to 15 | Integer | The number that comprises the HS-PDSCH sign indicating number in institute's assign group channel code |
| Initial code sign indicating number number | The C-number of |
1 to 15 | Integer | The initial code of institute's assign group channel code number |
Table one
In the above-mentioned table one, M represents that the parameter item of HS-PDSCH channel code number must have; The C-number of codes represents when HS-PDSCH channel code number is non-vanishing, and the parameter item of initial code sign indicating number number must have.
Step 203, Node B receives after Physical Shared Channel reshuffles signaling, reshuffle this group HS-PDSCH channel code of obtaining the RNC indication the signaling from Physical Shared Channel, be the dynamic assignment reasonably of each UE in the sub-district, make UE can use the HS-PDSCH channel that distributes for it to carry out high speed data transfer on the down link.
From the method for above-mentioned distribution HS-PDSCH channel code as can be seen, because 3GPP TS25.433-5c0 agreement regulation, RNC reshuffles signaling by Physical Shared Channel and indicates to the HS-PDSCH channel code of Node B continuously necessary, and one group of continuous channel code can only be arranged, and this group channel code is by the RNC static allocation.So, be UE when distributing the HS-PDSCH channel code at Node B, Node B can only be the UE distribution from Physical Shared Channel is reshuffled the HS-PDSCH channel code of signaling indication.At this moment, if also have other idle HS-PDSCH channel code in the sub-district, because RNC can not reshuffle signaling by Physical Shared Channel dynamically and simultaneously these idle HS-PDSCH channel code be indicated the B to Node, so Node B still can't distribute to UE with these idle HS-PDSCH channel code.Therefore, the method for existing distribution HS-PDSCH channel code greatly reduces the utilance of HS-PDSCH channel code resource.
