Embodiment two
With reference to Fig. 2, show flow chart of steps according to a kind of business transmitting method of the application embodiment two.
The business transmitting method of present embodiment may further comprise the steps:
Step S202: on a plurality of R4 carrier waves of a sub-district, set the time slot of waiting to be configured to HS-PDSCH.
When the R4 carrier wave with the sub-district is configured to R4 and HSDPA common carrier, can be merely a R4 carrier wave and be configured, also can be configured a plurality of R4 carrier waves.In the present embodiment,, the application's business transmitting method is described a plurality of R4 carrier waves are configured to R4 and the HSDPA common carrier is an example.Preferably, a plurality of is 2, and 2 R4 carrier waves are configured to R4 and the HSDPA common carrier is a kind of comparatively reasonable configuration, has both effectively utilized the idle time interval resource of R4 carrier wave, can guarantee the normal transmission that R4 is professional again.
When time slot to be disposed on the R4 carrier wave when being a plurality of, preferably, these a plurality of time slots are adjacent time slot, to reduce the performance impact of HS-PDSCH to adjacent DPCH.
Preferably, when R4 carrier wave to be disposed when being a plurality of, the time slot that is configured to HS-PDSCH on these a plurality of R4 carrier waves is identical time slot, as is TS4 and TS5, to reduce the phase mutual interference.
In the present embodiment, setting TS4 on a plurality of R4 carrier waves and TS5 time slot configuration is the HS-PDSCH time slot.
Step S204: with the time slot configuration of setting on a plurality of R4 carrier waves is the HS-PDSCH time slot, makes a plurality of R4 carrier waves become R4 and HSDPA common carrier.
Step S206: on R4 and HSDPA common carrier, configuration HS-SCCH and HS-SICH on other time slot except that being configured to the HS-PDSCH time slot.
HS-SCCH and HS-SICH can be by those skilled in the art rule of thumb or actual conditions, suitably configuration on other time slot except that being configured to the HS-PDSCH time slot.
The configuration of a kind of R4 and HSDPA common carrier is as shown in Figure 3, and visible from Fig. 3, HS-PDSCH is configured in the TS4 and the TS5 time slot of R4 carrier wave, and HS-SCCH is configured in the TS6 time slot, and HS-SICH is configured in the TS2 time slot.
Step S208: use the power offset values of setting; According to the maximum transmit power of HS-PDSCH in slow power control algolithm adjustment R4 and the HSDPA common carrier, the HSDPA business of using the transmission of HS-PDSCH time slot with reduction is to the professional interference of the R4 of adjacent area co-frequency co-time slot.
When HSDPA and the networking of R4 co-frequency co-time slot; The HSDPA identical networking of comparing independent; The HSDPA cell throughout has certain lifting; But because HSDPA shared channel power transmitted power higher (this channel only adopts slow power control), therefore, HSDPA shared channel place time slot can be to serious interference of the professional generation of the R4 of identical time slot.
For this reason, need to adopt corresponding Interference Control measure.In the present embodiment; For reducing the performance impact of HSDPA shared channel to R4; Maximum transmit power to the HS-PDSCH on R4 and the HSDPA common carrier limits, and promptly on the maximum transmit power basis, introduces the power excursion Δ, and is used in combination with HS-PDSCH slow power control algolithm; Suitably reduce the power of Cell Center User, can reduce interference.Certainly, in practical application, those skilled in the art also can adopt other suitable interference control method, and the application does not limit this.
Step S210: use adjusted R4 of HS-PDSCH maximum transmit power and HSDPA common carrier transport service.
When using R4 and HSDPA common carrier transport service, when the R4 in the access PS business in the sub-district is professional, then use the R4 in this PS business of HS-PDSCH slot transmission in R4 and the HSDPA common carrier professional; And/or the traffic carrying capacity of the R4 symmetrical service that inserts when the sub-district surpasses the DPCH time slot institute of the R4 carrier wave in the sub-district can the loaded service amount time, uses this R4 symmetrical service of HS-PDSCH slot transmission in R4 and the HSDPA common carrier; And/or, when the R4 in not having the PS business in the sub-district is professional, make the HS-PDSCH time slot in R4 and the HSDPA common carrier idle, professional to insert HSDPA; And/or the traffic carrying capacity of the R4 symmetrical service that inserts when the sub-district can the loaded service amount time, makes the HS-PDSCH time slot in R4 and the HSDPA common carrier idle, to insert the HSDPA business less than the DPCH time slot institute of the R4 carrier wave in the sub-district.By the way, can effectively utilize the HS-PDSCH time slot in R4 and the HSDPA common carrier, promote the H business throughput of sub-district.
Pass through present embodiment; On the identical time slot of a plurality of R4 carrier waves, dispose HS-PDSCH; And use the power offset values of setting; In conjunction with the slow power control algolithm maximum transmit power of HS-PDSCH in R4 and the HSDPA common carrier is adjusted, effectively controlled the H business, realized the utilization of R4 carrier wave idling-resource more effectively for the professional interference of the R4 of adjacent area co-frequency co-time slot.And, insert situation according to different service, select the proper carrier wave transmission means, also improved the efficient of using R4 carrier wave idling-resource.It is thus clear that through present embodiment, the R4 carrier resource that efficiently solves sub-district in the present TD-SCDMA network can not be used effectively, the problem that the resource utilization of sub-district is low reaches lifting sub-district H business throughput, and then promotes the effect of local resource utilance.
Embodiment three
With reference to Fig. 4, show flow chart of steps according to a kind of business transmitting method of the application embodiment three.
Present embodiment still carries out business and is transmitted as example a plurality of R4 carrier waves are configured to R4 and HSDPA common carrier, for single R4 carrier wave being configured to the situation that R4 and HSDPA common carrier carry out professional transmission, can be realized with reference to present embodiment by those skilled in the art.
The business transmitting method of present embodiment may further comprise the steps:
Step S302: with the setting time slot configuration of one or more R4 carrier waves of a sub-district is the HS-PDSCH time slot, makes the R4 carrier wave become R4 and HSDPA common carrier.
In the present embodiment, change the part R4 carrier wave in the sub-district or whole R4 carrier wave into R4 and HSDPA common carrier, on R4 and HDPA common carrier, descending 1 or 2 time slot fixed configurations is the HS-PDSCH time slot.A kind of R4 and the HDPA common carrier that are the HS-PDSCH time slot with descending 2 time slot fixed configurations dispose as shown in Figure 3.Need to prove, be that descending time slot is configured in the present embodiment, but in actual the use, can be configured ascending time slot equally, perhaps, uplink and downlink timeslot all is configured, concrete configuration by those skilled in the art according to the actual conditions flexible configuration.
When configuration a plurality of R4 and HSDPA common carrier, fix (being each R4 all is configured on the identical time slot with HS-PDSCH on the HSDPA common carrier) with the time slot configuration on the HSDPA common carrier for R4, the whole network is unified to dispose, with the mutual interference of minimizing phase.But allow R4 to seize the H time slot.
Step S304: the carrier selecting strategy is set.
After introducing R4 and HSDPA common carrier; Carrier type in the sub-district is divided into three kinds: R4 carrier wave, H carrier wave, R4 and HSDPA common carrier; Carrier wave priority in the existing network is suitably adjusted; Set the strategy of selecting carrier wave, promptly apply for preferentially inserting and switching on the H carrier wave when H is professional, can use R4 and HSDPA common carrier when the H carrier resource is not enough; Preferentially be linked into the R4 carrier wave for the R4 business, can not use R4 and HSDPA common carrier when the R4 resource perhaps has the R4 carrier wave inadequately, consider to seize the H carrier wave at last.
Perhaps; Can be set to by the carrier selecting strategy: when the R4 symmetrical service that inserts in the sub-district (CS is professional) increases or the R4 business of PS is arranged; Seize the H function through R4; System lets the R4 service occupation R4 of CS business or PS and the H resource in the HSDPA common carrier, thereby improves the professional access success rate of R4; When symmetrical service in the sub-district reduced and do not have the PS business, the H resource that frees out in R4 and the HSDPA common carrier can insert the HSDPA data service.
Step S306: the Interference Control of carrying out R4 and HSDPA common carrier.
When HSDPA and the networking of R4 co-frequency co-time slot; The HSDPA identical networking of comparing independent; The HSDPA cell throughout has certain lifting; But because HSDPA shared channel power transmitted power higher (this channel only adopts slow power control), therefore, HSDPA shared channel place time slot can be to serious interference of the professional generation of the R4 of identical time slot.
For reducing the performance impact of HSDPA shared channel to R4; Maximum transmit power to the HS-PDSCH on R4 and the HSDPA common carrier limits; Promptly on the maximum transmit power basis, introduce the power excursion Δ; And be used in combination with HS-PDSCH slow power control algolithm, suitably reduce the power of Cell Center User, can reduce interference.
A kind of HS-PDSCH slow power control algolithm that reduces interference is following: CQI (the Channel Quality Indicator that obtains revised HS-PDSCH; The channel quality indication) information; Comprise the information of data block size (TBS) or the information of code check in this CQI information; According to revised CQI, judge that code check or TBS N continuous time are greater than or equal to predefined threshold T h
Down, then descend step delta of adjusting power
Down(dB); Otherwise do not adjust power.Wherein, N is predefined positive integer, threshold T h
DownCan obtain through experiment simulation.
Adopt above-mentioned interference control method, the HS-PDSCH channel transmitting power that will be in the higher user of center of housing estate, throughput reduces, and can reduce the interference of HSDPA for the R4 user of its adjacent area co-frequency co-time slot.And do not adjust for being in the middle perhaps user's at edge the HS-PDSCH channel transmitting power in sub-district, can guarantee the speed of edge customer.
Step S308: use the R4 and the HSDPA common carrier transport service of having carried out Interference Control.
Pass through present embodiment; Situation to HSDPA and R4 adjacent area co-frequency co-time slot; Adopt proper carrier wave selection strategy and time slot configuration scheme, and the maximum transmit power of HS-PDSCH has been limited, thereby realized the Interference Control between HSDPA business and the R4 business.Disturbance restraining method and time slot carrier selecting method when R4 through present embodiment and H common carrier; Can reduce the HSDPA business for the professional interference of the R4 of adjacent area co-frequency co-time slot; And then the mode through R4 and H common carrier, can effectively utilize the idle time slot on the R4 carrier wave, it is configured to the HS-PDSCH time slot; Promote the HSDPA throughput of sub-district, improve the resource utilization of sub-district.
