In the single carrier ascending packet data processing procedure of R7 standard, at first carry out the Traffic Channel of HSUPA and the foundation of control channel, to scheduling and non-scheduled transmission allocation of channel resources may.When user terminal inserts, obtain the Traffic Channel of this terminal and the resource information of uplink/downlink control channel from network side; In the data dispatch transmission course, UE reporting scheduling information (SI, Scheduling Information) information is come assistant base station (Node B) scheduling, and described SI information comprises:

Priority of logical channels sign (HLID, Highest priority Logical channel ID): be used to identify the ID of logic channel, different HLID have directly reflected the height of priority, and the base station judges that in view of the above the UE service priority dispatches.

The total cache size (TEBS, Total E-DCH BufferStatus) of the transmission channel (E-DCH) that strengthens, because the business of UE may be multiple, the cache size of these all HSUPA business of TEBS field identification.

Highest priority logical channel buffer status (HLBS, Highest priority Logical channelBuffer Status), what of total buffer data size this field identification limit priority buffer data size account for, thereby the cache information of UE can further be understood in the base station.

Available dump power (UPH, UE Power Headroom): this field identification UE maximum transmission power deduction path loss and disturb after also have much surpluses, thereby base station power controlling more accurately.

The path loss size value of Serving cell and neighbor cell (SNPL, Server and Neighbourcell Path Loss), the base station can be judged the approximate location of UE in the sub-district in view of the above, thereby effectively controls the interference of minizone.

When UE inserted for the first time, SI information went up at enhanced uplink random access channel (E-RUCCH) and sends, and network side is UE allocation schedule resource pool and non-scheduling resource, and in transmission course, SI information transmits in the MAC-e of E-DCH channel head.For scheduled transmission, the base station is according to receiving the mass measurement that strengthens uplink physical channel (E-PUCH), the CRC check information that receives data and the up-to-date SI information that the base station end is kept last time, UE is dispatched, by strengthening the scheduling grant control information of down control channel (E-AGCH) transmission to the user, comprise power, time slot, code channel information etc., UE is after receiving the E-AGCH schedule information, carry out transformat combination (E-TFC) according to scheduling grant and select, send grouped data by the E-PUCH channel then.Non-scheduled transmission is in the RNC reserved resource and transmit in the time.

When the single carrier HSUPA of the current agreement of R7 ascending packet data transmits, because Traffic Channel and control channel are all on a carrier wave, particularly the resource that can be used in HSUPA when this carrier wave has in limited time very much, and the peak rate that adopts the HSUPA technology to send data will be subject to channel.

In order further to improve peak rate, minimize the system complex of forward compatibility simultaneously, the technical scheme of a plurality of carrier wave HSUPA has been proposed at present.

According to above-mentioned analysis, in five amounts of SI information, the TEBS of each carrier wave, HLBS, HLID are identical, the SNPL difference of each carrier wave is also very little, only report the SNPL of main carrier to get final product, that each carrier wave difference is bigger is UPH, so the SI information of different carrier need be determined in the base station.

In view of the These characteristics of a plurality of carrier wave SI information, above-mentioned steps 101 and step 102 can have following several concrete processing method:

First method: in step 101, described UE reports the SI information of a plurality of carrier wave correspondences that this UE supports, and reports the SI information of a carrier wave correspondence on each carrier wave respectively; If for example UE uses 3 carrier waves, then report 3 SI, among the described SI, TEBS, HLBS, HLID, SNPL are all identical, the UPH difference, the SI of this carrier wave correspondence can report on this carrier wave also and can report on other carrier wave, and preferably method is to report on this carrier wave.In step 102, described base station receives the SI information that UE reports on each carrier wave, be the SI information that carrier wave is complete because each carrier wave reports, so each self-corresponding SI information of described a plurality of carrier wave can directly be determined in the base station.

Second method: in step 101, described UE reports the SI information of a plurality of carrier wave correspondences that this UE supports, and the SI information of described each carrier wave correspondence placed on the carrier wave reports; In step 102, described base station receives the SI information of described a plurality of carrier wave correspondences on the carrier wave of described SI reporting information, because the SI information of each carrier wave correspondence is complete SI information, so each self-corresponding SI information of described a plurality of carrier wave can directly be determined in the base station.

The third method: in step 101, described UE only reports a SI information, wherein comprises HLID, TEBS, HLBS and SNPL, and each self-corresponding UPH information of a plurality of carrier wave; In step 102, the content of the described SI information of receiving is resolved in described base station, obtain each the self-corresponding UPH information of HLID, TEBS, HLBS, SNPL and described a plurality of carrier wave in the SI information, determine that the SI information of each carrier wave correspondence is: the UPH information of described HLID, TEBS, HLBS, SNPL and this carrier wave correspondence.

The 4th kind of method:

In step 101, described UE only reports the SI information of a carrier wave correspondence, and only comprises described HLID, TEBS, HLBS, SNPL and the UPH information that reports the carrier wave correspondence in this SI information.The carrier wave of the UPH information correspondence that herein this is reported is called and reports carrier wave, will report other carrier wave the carrier wave to be called the non-carrier wave that reports except described in a plurality of carrier waves that described UE uses.

In step 102, specifically comprise:

B1, on described base station, safeguard the interference power of a plurality of carrier waves, upgrade according to the initial value and the corresponding TPC order of each carrier-in-interference power.Described base station is according to formula $P_{\mathrm{ebase}}\left(t\right)=P_{\mathrm{ebase},\mathrm{ini}}+\underset{i=0}{\overset{t}{\mathrm{\Σ}}}\mathrm{TPC}\·\mathrm{\Δstep}$ Determine the interference power of each carrier wave, wherein said P _Ebase(t) be that carrier wave is at current scheduling interference power at interval, P _{Ebase, ini}The high-rise pre-configured carrier wave initial interference power of serving as reasons, For controlling the TPC total amount from initial to current scheduling through-put power at interval, Δ step is default TPC step-length.

The non-UPH that reports carrier wave in described a plurality of carrier wave is calculated according to the described UPH of carrier wave and the interference power of described each carrier wave of reporting in B2, base station.

B3, determine that the non-SI information of carrier wave that reports is in described a plurality of carrier wave: described HLID, TEBS, HLBS, SNPL and this non-UPH information that reports the carrier wave correspondence.

In step B2, two kinds of processing modes can be arranged:

First kind of concrete processing method of step B2 may further comprise the steps B21 and step B22.

B21, according to formula $\mathrm{UPH}=\frac{P_{\max }}{P_{\mathrm{ebase}}\·L}$ Determine the path loss parameter, wherein UPH is the UPH that UE reports, P _MaxFor the UE maximum transmission power or report the maximum transmission power of carrier wave, and the power sum of a plurality of carrier waves do not exceed the maximum transmission power of UE, and the maximum transmission power of each carrier wave is no more than the maximum transmission power of UE; P _EbaseFor reporting the interference power of carrier wave, L is the path loss parameter;

B22, basis $\mathrm{UPH}=\frac{P_{\max }}{P_{\mathrm{ebase}}\·L}$ Determine the non-UPH that reports carrier wave, wherein P in a plurality of carrier waves _EbaseBe the non-interference power that reports carrier wave; P _MaxBe UE maximum transmission power or the non-maximum transmission power that reports carrier wave, the path loss parameter that L determines for step B21.

Second kind of processing method of described step B2 specifically may further comprise the steps b21 to step b23:

B21, according to formula $\mathrm{UPH}=\frac{P_{\max }}{P_{\mathrm{ebase}}\·L}$ Determine to report the path loss parameter of carrier wave, wherein UPH is the UPH that UE reports, P _MaxFor the UE maximum transmission power or report the maximum transmission power of carrier wave, P _EbaseFor reporting the interference power of carrier wave, L is the path loss parameter that reports carrier wave.

B22, determine non-carrier wave and the described path loss parameter difference that reports intercarrier of reporting, path loss parameter that reports carrier wave and the described path loss parameter difference of determining according to described step b21 determined each non-path loss parameter that reports carrier wave in described a plurality of carrier wave again.

The present invention can determine path loss parameter difference between the different carrier according to COST 231-Hata model, and concrete mode is as follows:

According to COST 231-Hata model formation:

L _b＝46.3+33.9lg?f-13.82lg?h _b-a(h _m)+(44.9-6.55lg?h _b)lg?d+C _m

Calculate the large scale path loss L of each carrier wave _bWherein:

A (h _m) be the travelling carriage height correction factor;

C _mValue is as follows:

0dB, the medium-sized city that the density of trees is moderate and the center in suburb,

3dB, the center, big city;

F is the frequency of carrier wave, and scope is: 1500-2000MHz;

h _bHeight for the engineering antenna is generally: 30-200m;

h _mHeight for UE is generally: 1-10m;

D is the distance between UE and base station, is generally: 1-20km;

Above-mentioned parameter can be pre-configured, perhaps by the base station by obtaining alternately with UE.

Calculate the path loss parameter difference of described each carrier wave by above-mentioned COST 231-Hata model formation, the described path loss parameter addition that reports carrier wave with this path loss parameter difference and step b21 calculate obtains the non-path loss parameter that reports carrier wave.

For example carrier wave A is for reporting carrier wave, and carrier wave B is the non-carrier wave that reports, and then at first calculates the path loss parameter difference l=L between carrier wave A and the carrier wave B _BB-L _BA=33.9lgf _B-33.91gf _A, the UPH that reports according to carrier wave A calculates L then _A, can determine that the path loss parameter of carrier wave B is: L _A+ l.

B23, base station basis

Determine the described non-UPH that reports carrier wave, wherein P _EbaseBe the non-interference power that reports carrier wave; P _MaxBe default UE maximum transmission power or the non-maximum transmission power that reports carrier wave, L is the non-path loss parameter that reports carrier wave.

In step 103, after the SI information that reports according to UE when the base station had been determined the SI information of each carrier wave, the base station was a plurality of allocation of carriers signal powers, dispatches with allocation result; And, when the signal power of a plurality of carrier waves of scheduling, whether the ratio of judging the maximum signal power of each carrier wave and interference power is greater than the UPH in the SI information of this carrier wave, if greater than, then reduce the signal power of this carrier wave, suppose that the carrier wave that UE supports has N, when scheduling, n carrier wave wherein need satisfy:

Simultaneously, the base station judges that the interference power sum of each carrier wave in described a plurality of carrier wave adds that whether the signal power sum is greater than default gross power, if greater than, then reduce the signal power of carrier wave, for example the carrier wave that UE supported has three, difference called after carrier wave A, B, C, corresponding interference power is respectively P _{Ebase, A}, P _{Ebase, B}, P _{Ebase, C}, corresponding signal power is respectively: P _{S, A}, P _{S, B}, P _{S, C}, then promptly need satisfy P _{Ebase, C}+ P _{Ebase, B}+ P _{Ebase, A}+ P _{S, A}+ P _{S, B}+ P _{S, C}≤ P _RoT, P wherein _RoTBe default gross power.

Described base station is that the method for a plurality of allocation of carriers signal powers can be the signal power of distributing a plurality of carrier waves according to the water filling theorem.The signal power that is described n carrier wave is: $P_{s,n}=\frac{P_{\mathrm{RoT}}}{N}-P_{\mathrm{ebase},n}.$

As another kind of execution mode, described base station be a plurality of allocation of carriers signal powers method can also for: the principle that equates with interference power ratio according to the signal power of each carrier wave in a plurality of carrier waves is each allocation of carriers signal power.Promptly according to each carrier wave

Equate to come distributing signal power.For example: above-mentioned three carrier wave A, B, C need satisfy simultaneously $\frac{P_{s,A}}{P_{\mathrm{ebase},A}}=\frac{P_{s,B}}{P_{\mathrm{ebase},B}}=\frac{P_{s,C}}{P_{\mathrm{ebase},C}},$ And the signal power that can calculate each carrier wave is as follows:

$P_{s,A}=(\frac{P_{\mathrm{RoT}}}{P_{\mathrm{ebase},A}+P_{\mathrm{ebase},B}+P_{\mathrm{ebase},C}}-1)\×P_{\mathrm{ebase},A};$

$P_{s,B}=(\frac{P_{\mathrm{RoT}}}{P_{\mathrm{ebase},A}+P_{\mathrm{ebase},B}+P_{\mathrm{ebase},C}}-1)\×P_{\mathrm{ebase},B};$

$P_{s,C}=(\frac{P_{\mathrm{RoT}}}{P_{\mathrm{ebase},A}+P_{\mathrm{ebase},B}+P_{\mathrm{ebase},C}}-1)\×P_{\mathrm{ebase},C}.$

For a plurality of carrier wave HSUPA system, owing to adopted a plurality of carrier channels, it is bigger that the channel condition of each carrier wave might differ, for example one is adopted three carrier wave HSUPA systems, for carrier wave A, adjacent sub-district load on this carrier frequency is heavier, and is therefore bigger to the interference of this cell carrier A, can badly influence the efficiency of transmission of system.There is following relation: P in the interference of supposing three carrier waves that base station end and UE end is kept and adjusted according to TPC _{Ebase, C}〉=P _{Ebase, B}〉=P _{Ebase, A}, then can get P _{S, A}〉=P _{S, B}〉=P _{S, C}

The base station is after obtaining the signal power of each carrier wave, according to the dispatching method of single carrier, carry out channel resource allocation for each carrier wave according to HLID, TEBS in the SI information of each carrier wave, HLBS, SNPL and above-mentioned power constraint condition (mainly retraining) by UPH information.On E-AGCH, notify the time-slot code channel resource and the power resource of each carrier wave then.
