Description
Technical field
The present invention relates to mobile communication technology, particularly a kind of methods, devices and systems of resource distribution.
Background technology
In moving communicating field, along with the development of miscellaneous service, user has proposed more and more higher requirement for the speed of transfer of data.In order to support the data service of higher rate, lower time delay, higher throughput and the availability of frequency spectrum, two kinds of new technology have been proposed, high speed downlink packet access (HSDPA, High Speed Downlink Packet Access) and high speed uplink packet access (HSUPA, High Speed Uplink Packet Access) technology.
HSUPA technology has been introduced new physical channel, new physical channel comprises for carrying enhancing dedicated channel (E-DCH, Enhanced Dedicated Channel) the E-DCH Dedicated Physical Data Channel (E-DPDCH of upstream data information, E-DCH Dedicated Physical Data Channel), and for carrying the E-DCH Dedicated Physical Control Channel (E-DPCCH, E-DCH Dedicated Physical Control Channel) of up signaling information of E-DCH.
Before introducing above-mentioned new physical channel, because data rate improves, the data block of transmission data increases, make according to Dedicated Physical Control Channel (DPCCH, Dedicated Physical Control Channel) carry out the degradation of channel estimating, cannot meet the performance requirement of high speed data transfer demodulation.Cause the problems referred to above to be mainly because: in order to make the performance of up-high speed transmission reach optimum, just the difference power between E-DPDCH and DPCCH need to be controlled in certain scope, and ensure that this difference power is controlled within a certain range the power that just need to promote DPCCH, also just need to promote DPCCH signal to noise ratio (DPCCH SIR) simultaneously.But adjust signal-to-noise target value (SIRtar, Signal-to-Interference Ratio Target) exterior ring power control (OLPC, Out Loop Power Control) process is a process at a slow speed, if the adjustment of SIR is too fast, just may cause OLPC cannot catch up with the demand that SIR changes.Therefore,, may occur needing larger SIR under high-speed case time, SIRtar is still in lower value.Now, can cause the error rate under high-speed case significantly to promote, and have a strong impact on throughput.
Therefore,, introducing after E-DPCCH, in order to improve the accuracy of channel estimating, E-DPCCH is also joined in channel estimating.In the time that E-DPCCH also adds channel estimating, by power lifting (power boost) characteristic of E-DPCCH, the difference power of E-DPCCH and E-DPDCH can be controlled in the scope of performance permission, the requirement of signal to noise ratio also can meet power variation simultaneously time.Thus, the accuracy of channel estimating improves greatly.
But in the prior art, radio network controller (Radio Network Controller, RNC) cannot be in the time carrying out resource distribution, for thering is the wireless link distribution E-DPCCH power boost resource of UE of E-DPCCH power boost ability.Even thereby cause UE to there is E-DPCCH power boost ability, cannot utilize the power boost characteristic of E-DPCCH to carry out channel estimating, still can there is high speed data transfer time, channel estimating is inaccurate, the problem of data demodulates degradation.

Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
In each of the embodiments described below, wireless communication system is with WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) system is example, but can generally be applied in other wireless communication systems, for example be applied in LTE (Long Term Evolution, Long Term Evolution project) system.RNC, Node B and UE in other wireless communication systems have different titles, but also can be suitable for the embodiment of the present invention.
Between UE and Node B, set up Radio Resource control connection (Radio Resource Control Connection, RRC Connection) time, UE can be in RRC connection request (RRC Connection Request) message or RRC connect and set up in (RRC Connection Setup Complete) message, report this UE whether to possess E-DPCCH power boost ability to RNC.But, synchronize the configuration of Node B and ability information with Node B during at RNC, Node B may not can this Node B of active reporting whether there is E-DPCCH power boost ability.Therefore, can cause RNC cannot correctly know the ability information of Node B, correctly allocation radio resource.
For example, RNC may give tacit consent to RNC and not report that to have E-DPCCH power boost ability be exactly not have this ability, carrying out wireless link (Radio Link, RL) configuration or when RL reprovision, can not notify Node B is the wireless link distribution E-DPCCH power boost resource of current UE.That is to say that Node B can not use E-DPCCH power boost characteristic to carry out channel estimating to current UE.Now, even if UE has had E-DPCCH power boost, ability also cannot be used this characteristic, and UE and Node B still use DPCCH to carry out channel estimating, still exist channel estimation accuracy low, the problem that the error rate is high while causing high speed data transfer.
Therefore, need to make RNC can clearly know whether Node B has the ability of E-DPCCH power boost, to configure optimum Radio Resource for Node B and UE.
As shown in Figure 1, the first embodiment of the present invention provides a kind of method of resource distribution, and the method comprises:
Step 101, obtains the ability information of Node B, and this ability information comprises whether Node B has E-DPCCH power boost ability;
Step 102, obtains the ability information of UE, and this ability information comprises whether UE has E-DPCCH power boost ability;
Step 103, in the time that UE and Node B all have E-DPCCH Power boost ability, notifying this Node B is that current UE configuration adopts channel power lifting ability to carry out the resource of channel estimating.
The implementation that the each step of the present embodiment is concrete will specifically describe in the following embodiments.
The present embodiment obtains the ability information of Node B and the ability information of UE by RNC, and according to the above-mentioned ability information of obtaining, for current UE configuration Node B is for the resource of channel estimating optimum, thereby make in the time that UE and Node B all have channel power lifting ability, Node B can adopt channel power lifting ability to carry out channel estimating, realize the raising of channel estimation accuracy, also can reduce the error rate of high speed data transfer simultaneously.
Specifically describe the second embodiment of the present invention below in conjunction with accompanying drawing 2.The second embodiment of the present invention also provides a kind of method of resource distribution, and the method comprises:
Step 201, RNC is synchronizeed configuration and the ability information of Node B with Node B.
In step 201, the configuration of the synchronous Node B of RNC and ability information can be passed through resource audit process, also can indicate process by resource status, or both combinations.
In the time completing RNC by resource audit process and synchronize the configuration of Node B and ability information with Node B, RNC sends resource audit request to Node B and starts resource audit process.In this process, the resource audit response message that RNC sends by Node B is known configuring condition and the ability information etc. of Node B.By this process, RNC can complete the synchronous of Node B configuring condition and logical resource state.
Can clearly know in order to make RNC whether Node B has the ability of E-DPCCH power boost, Node B is in resource audit response message, carrying an information unit (Information Element, IE) is used to indicate this Node B and has E-DPCCH power boost ability or do not have this ability.
Therefore, RNC can clearly know whether Node B can use E-DPCCHpower boost characteristic by the resource IE whether the instruction Node B that carries in response message have an E-DPCCH power boost ability that audits.
Resource audit process can be triggered in multiple situation, not necessarily before following step is carried out, is just triggered.For example, start, switch at RNC or when community situation changes, RNC will initiate resource audit process.
In the time completing RNC by resource status instruction process and synchronize the configuration of Node B and ability information with Node B, RNC receives the resource status Indication message that Node B sends, and completes the synchronous of the configuration of Node B and ability information according to this message.In this resource status Indication message, carry the multiple IE that are used to indicate Node B configuring condition and logical resource state, comprising being used to indicate Node B and whether having the IE of E-DPCCH power boost ability.
Whether RNC has the IE of E-DPCCH power boost ability by the Node B carrying in resource status Indication message, can this Node B of knowing that can be clear and definite use E-DPCCH power boost characteristic to carry out channel estimating.
Node B sends resource status Indication message to RNC and can be triggered under many circumstances, and not necessarily will before subsequent step is carried out, just carry out.For example increase the home cell of Node B; Delete the home cell of Node B; The situations such as the ability of home cell changes all may trigger Node B and send resource status Indication message to RNC.
Above-mentioned resource audit process and resource status instruction process all can realize, and make RNC clearly know whether Node B has E-DPCCH power boost ability.Meanwhile, both be combined with the synchronizing process that also can complete RNC and obtain the ability information of Node B.Because resource audit process exists different with the trigger condition of resource status instruction process, so, there is not the priority in order in both triggerings, there is not mutual repulsion yet, can be combined with, thereby more fully ensure, whether initiate RRC at UE connects while setting up RNC and has understood accurately Node B and can use E-DPCCH power boost characteristic to carry out channel estimating, better ensure the accuracy of UE and Node B channel estimating, reduce the error rate of high speed data transfer between UE and Node B.
Step 202, RNC receives the message that UE sends, and knows the ability of UE.
In the time that UE initiates RRC connection, UE can be by sending the message initiated RRC establishment of connection of RRC Connection Request process to RNC.In RRC Connection Request message, can carry the ability of this UE of part.In the RRC Connection Setup Complete message sending to RNC at UE, the ability that can carry the whole UE that do not carry in RRC Connection Request message.By receiving above-mentioned two message, RNC can be known the ability that UE is whole.
In whole ability of the UE that RNC is known by above-mentioned two message, comprise whether UE has E-DPCCH power boost ability.Therefore, RNC can connect process of establishing by RRC, clearly knows whether UE has E-DPCCH power boost ability.
Step 203, RNC, according to the ability of UE, is the resource of UE configuration Node B.
Receive at RNC after the RRC Connection Request message of UE transmission, RNC can be according to the part ability of the UE carrying in this message, and notice Node B is the resource on UE configuration Node B, i.e. the foundation of RL.And, receive at RNC the RRC Connection Setup Complete message that UE sends, know after whole abilities of UE, can again notify Node B to reconfigure the resource of Node B according to the whole ability of UE, RL reconfigures.
Through step 201, what RNC was clear and definite knows whether Node B has E-DPCCH power boost ability; Through step 202, what RNC was clear and definite knows whether UE has E-DPCCH power boost ability.Therefore,, in step 203, RNC sets up and RL reprovision process by RL, can be the resource of the configuration Node B of UE optimum.For example, in the time that Node B and UE all have E-DPCCH power boost ability, RNC can pass through RL process of establishing and RL reprovision process, and notice Node B carries out resource distribution and uses E-DPCCH power boost characteristic to carry out channel estimating to current UE, thereby improves channel estimation accuracy.
By the above-mentioned steps of the present embodiment, RNC can be clear and definite the Node B of knowing whether there is E-DPCCH power boost ability, thereby in the time that UE and Node B all have E-DPCCH power boost ability, for using E-DPCCH power boost characteristic, current UE configuration Node B carries out channel estimating.According to the present embodiment, in the time that RNC configuration Node B uses E-DPCCH power boost characteristic to carry out channel estimating, can improve the accuracy of UE and Node B channel estimating, thereby guarantee the accuracy of high speed data transfer between UE and Node B, improve throughput.
In addition, RNC configures after the resource of Node B, can also further be configured the resource at UE place, for example, by radio bearer (Radio Bearer, RB) set up or RB reconfigures process the resource at UE place is configured, to reach the consistent of UE and Node B resource distribution.
Specifically describe the third embodiment of the present invention below in conjunction with accompanying drawing 3.Third embodiment of the invention provides a kind of method of resource distribution in UE moving process, and the method comprises:
Step 301, Drift Radio Network Controller (Drift RNC, DRNC) is synchronizeed configuration and the ability information of Node B with Node B.
DRNC is by resource audit process or resource status instruction process, or configuration and the ability information of Node B are synchronizeed in both combinations with Node B, thereby know whether Node B has E-DPCCHpower boost ability, and its specific implementation is with reference to the step 201 in second embodiment of the invention.
Step 302, Serving RNC (Serving RNC, SRNC) receives the message that UE sends, and knows the ability of UE.
UE connects process of establishing by RRC, can report its whole abilities to SRNC.Accordingly, SRNC can clearly know whether UE has E-DPCCH power boost ability.Specific implementation is with reference to the step 202 in second embodiment of the invention.
Step 303, SRNC is known the ability information of Node B.
The ability information of DRNC can be known it Node B by synchronizing process is transmitted to SRNC, and thus, SRNC can clearly know whether Node B has E-DPCCH ability.
For example, whether DRNC can be by shifting in instruction (Uplink Signaling Transfer Indication) message in up signaling, increase by one and be used to indicate the IE whether Node B have E-DPCCH power boost ability and notify this Node B of SRNC can use E-DPCCH power boost characteristic to carry out channel estimating.
For example, whether DRNC can also be by RL response (RL Response) message, increase by one and be used to indicate the IE whether Node B have E-DPCCH power boost ability and notify this Node B of SRNC can use E-DPCCH power boost characteristic to carry out channel estimating.
The ability information that DRNC can also forward Node B to SRNC by the interaction message between other and SRNC, is not limited to above-mentioned two kinds of modes.
Step 304, SRNC, according to the ability of current UE, is the resource of this UE configuration Node B.
SRNC is in step 303, and whether the know Node B clear and definite by the forwarding of DRNC has E-DPCCH power boost ability.Therefore,, in the time of the resource for UE configuration Node B, whether RNC can have E-DPCCH power boost ability according to UE is whether UE configuration Node B uses E-DPCCH power boost characteristic to carry out channel estimating.The specific implementation of its configuration can be with reference to the step 203 in second embodiment of the invention.
In the present embodiment, between step 301 and step 302, on carrying out, there is no specific sequencing.Because step 301 is known the ability information of Node B for DRNC, step 302 is known the ability information of UE for SRNC, and these two steps are completed by DRNC and SRNC respectively, not specific associated, so there is no specific sequencing on carrying out.Step 303 need to be carried out after step 301, the ability of Node B could be transmitted to SRNC afterwards because DRNC has been known the ability of Node B.But between step 303 and step 302, there is no specific sequencing, because step 302 is known UE ability for SRNC, and step 303 is DRNC forwards ability from Node B to SRNC, not necessarily there is specific association between the two, so there is not specific execution sequencing.
A third embodiment in accordance with the invention, DRNC can pass through resource audit process, resource status instruction process or both combinations, clearly knows whether Node B has E-DPCCH power boost ability.Forward Node B by DRNC to SRNC and whether have E-DPCCH power boost ability, SRNC can clearly know that Node B could use this characteristic to carry out channel estimating.Thus, whether the clear and definite understanding UE of SRNC and Node B have the ability of E-DPCCH power boost.So, in the time that UE and Node B all have E-DPCCH power boost ability, for this UE configuration Node B uses E-DPCCH power boost characteristic to carry out channel estimating, thereby can improve the accuracy that UE estimates at mobile context lower channel, reduce the error rate of high speed data transfer under this scene.
In addition, RNC configures after the resource of Node B, can also further be configured the resource at UE place, to reach the consistent of UE and Node B resource distribution.
Specifically describe the fourth embodiment of the present invention below in conjunction with accompanying drawing 4.The 4th embodiment provides a kind of method of resource distribution, and the method comprises:
Step 401, RNC is known UE ability information.
UE connects in the process of setting up at initiation RRC, can report its whole ability information to RNC, and therefore, what RNC can be clear and definite knows whether UE has E-DPCCH power boost ability.Specific implementation can be with reference to the step 202 in the second embodiment of the present invention.
Step 402, RNC is according to the resource on the capacity scheme Node B of UE.
Node B, when synchronize its ability information with RNC, does not report it whether to have E-DPCCHpower boost ability, and now RNC gives tacit consent to this Node B and has E-DPCCH power boost ability.Therefore,, while at RNC according to the ability of current UE being the resource on this UE configuration Node B, if this UE has E-DPCCH power boost ability, RNC can carry out channel estimating for its configuration Node B uses E-DPCCH power boost characteristic.
Therefore, RNC, in the process of RL foundation or RL reprovision, can give Node B configuration E-DPCCHpower boost relevant parameter.
Step 403, RNC reconfigures the resource on Node B according to the feedback of Node B.
In the time that Node B does not have E-DPCCH power boost ability, can feed back wireless link failed message to RNC, and in wireless link failed message, carry and set up failed reason.If wireless link is unsuccessfully because Node B does not have E-DPCCH power boost ability, this Node B comprises that to the failure cause of RNC feedback this Node B of instruction does not have E-DPCCH powerboost ability.
RNC is receiving after the failure cause of Node B feedback, this Node B of knowing that can be clear and definite does not have E-DPCCH power boost ability, again initiate the foundation of wireless link, and in this foundation request, no longer give the Node B configuration E-DPCCH power relevant parameter of boost.
In the present embodiment, step 403 not necessarily needs to carry out, if Node B has E-DPCCHpower boost ability, without execution step 403, because when Node B has this ability, just can adopt this characteristic to carry out channel estimating, can therefore not return to wireless link failure.
According to fourth embodiment of the invention, whether RNC has E-DPCCH power boost ability and gives tacit consent to it and have this ability because Node B does not report in synchronizing process, therefore in the time that UE has E-DPCCH power boost ability, can be that this UE configuration Node B uses E-DPCCH power boost characteristic to carry out channel estimating because RNC acquiescence Node B has E-DPCCH power boost ability, thereby improve the quality of channel estimating, the error rate while reducing high speed data transfer.
In addition, a fourth embodiment in accordance with the invention, in the time that Node B does not have E-DPCCH power boost ability, although RNC can give tacit consent to Node B because Node B does not report it whether to have this ability has this ability in synchronizing process, but still can be in the process reconfiguring the ability of clear and definite Node B, can not cause to Node B with to the inconsistent problem of the configuration of UE.
Specifically describe the fifth embodiment of the present invention below in conjunction with accompanying drawing 5.The 5th embodiment provides a kind of UE method of resource distribution in moving process, and the method comprises:
Step 501, SRNC is known the ability of UE, its specific implementation can be with reference to the step 302 in third embodiment of the invention.
Step 502, SRNC, according to the ability of current UE, is the resource of its configuration Node B.
Node B is synchronizeed the ability information of Node B during with DRNC, Node B does not report it whether to have E-DPCCH power boost ability, and DRNC gives tacit consent to this Node B and has E-DPCCH powerboost ability.
In the time that DRNC forwards the ability information of Node B to SRNC, can not forward Node B yet and whether there is E-DPCCH power boost ability, now SRNC can give tacit consent to Node B and has E-DPCCHpower boost ability.
Therefore,, in the time that SRNC is the resource of UE configuration Node B, if UE has E-DPCCHpower boost ability, SRNC can carry out channel estimating for UE configuration Node B uses E-DPCCH power boost characteristic.Now, SRNC issue DRNC RL set up or RL reallocation message in can carry E-DPCCH power boost relevant parameter, and DRNC issue Node B RL set up or RL reallocation message in also can carry E-DPCCH power boost relevant parameter.
Step 503, SRNC reconfigures the resource of Node B according to the feedback of Node B.
In the time that Node B does not have E-DPCCH power boost ability, if UE has this ability, SRNC meeting has this ability because of acquiescence Node B and is that UE configuration Node B uses E-DPCCHpower boost characteristic to carry out channel estimating.
Now, Node B, owing to not having E-DPCCH power boost ability, can set up failed message to DRNC feedback RL, carries the failure cause of indicating Node B not have this ability in this message.Set up after failed message at the RL that receives Node B feedback, DRNC can feed back RL to SRNC and set up unsuccessfully, and carries failure cause and indicate Node B not have E-DPCCH power boost ability.Recognize that at SRNC it is unsuccessfully not have due to Node B after E-DPCCH power boost ability that RL sets up, SRNC again initiates RL and sets up or RL reprovision, and no longer configures E-DPCCH power boost relevant parameter in RL foundation or the request of RL reprovision.
According to fifth embodiment of the invention, whether DRNC has E-DPCCH power boost ability and gives tacit consent to it and have this ability because Node B does not report in synchronizing process, and SRNC also can give tacit consent to Node B and has this ability thus.Therefore in the time that UE has E-DPCCH power boost ability, can be that this UE configuration Node B uses E-DPCCH power boost characteristic to carry out channel estimating because SRNC acquiescence Node B has E-DPCCH power boost ability, thereby improve the quality of channel estimating, the error rate while reducing high speed data transfer.
In addition, a fourth embodiment in accordance with the invention, in the time that Node B does not have E-DPCCH power boost ability, although DRNC can give tacit consent to Node B because Node B does not report it whether to have this ability has this ability in synchronizing process, and therefore SRNC also can give tacit consent to Node B and have this ability.But still can pass through Node B feeding back unsuccessful reason, be reconfigured the resource of Node B by SRNC, can not cause to Node B with to the inconsistent problem of the configuration of UE.
Known in conjunction with the fourth embodiment of the present invention and the 5th embodiment, in the time that the RNC of the 4th embodiment is SRNC, can think that the method providing in the 4th embodiment also can realize in the 5th embodiment the problem of resource distribution under mobile context.Because DRNC does not have decision making function in the 5th embodiment, just play a transmittance process, still finally grasped the ability information of UE and Node B by SRNC, and carry out resource distribution according to both ability information.
Specifically describe the sixth embodiment of the present invention below in conjunction with accompanying drawing 6.The 6th embodiment provides a kind of method of resource distribution, and the method comprises:
Step 601, RNC is known the ability information of UE, its specific implementation is referring to the step 202 in second embodiment of the invention.
Step 602, RNC, according to the ability of current UE, is the resource of this UE configuration Node B.
RNC with the synchronizing process of Node B in, Node B can not report it whether to have E-DPCCH power boost ability.In the case, RNC gives tacit consent to this Node B and has E-DPCCH power boost ability.
Therefore,, in the time that UE has E-DPCCH power boost ability, RNC can use E-DPCCH power boost characteristic to carry out channel estimating for this UE configuration Node B.
Step 603, Node B carries out resource distribution according to the ability of oneself.
In the time that Node B is not had E-DPCCH power boost ability, if UE has this ability, RNC meeting has this ability because of acquiescence Node B and is Node B configuration E-DPCCH power boost relevant parameter.Now, Node B can adopt DPCCH to carry out channel estimating because oneself does not have this ability.
The resource allocation method providing in the present embodiment also can be applied under mobile context.In mobile context time, the RNC in the present embodiment is SRNC, and SRNC forwards the ability information of obtaining Node B by DRNC, and in the time not forwarding Node B and whether have E-DPCCH power boost ability, acquiescence Node B has this ability.Therefore, SRNC, in the time that UE has E-DPCCH power boost ability, can be Node B configuration E-DPCCH power boost relevant parameter.Node B can be according to self-ability, determines whether adopt E-DPCCH power boost characteristic to carry out channel estimating.
According to sixth embodiment of the invention, RNC can be in the time that Node B report it whether to have E-DPCCH power boost ability, acquiescence Node B has this ability, and in the situation that UE has E-DPCCH power boost ability, be Node B configuration E-DPCCH power boost relevant parameter.Therefore, in the time that UE and Node B all have E-DPCCH power boost ability, RNC can make UE and Node B can adopt this characteristic to carry out Multiple Channel Analysis by resource distribution, improves Multiple Channel Analysis accuracy, reduces the error rate of high speed data transfer.
Specifically describe the seventh embodiment of the present invention below in conjunction with accompanying drawing 7.The 7th embodiment provides a kind of RNC710, and this RNC710 comprises:
Receiver module 711, the ability information reporting for receiving Node B720 and UE730, the ability information that wherein Node B720 reports comprises whether instruction Node B720 has the IE of channel power lifting ability;
Notification module 712, if UE730 and Node B720 all have the ability of channel power lifting, is that UE730 configuration adopts channel power lifting ability to carry out the resource of channel estimating for notifying Node B720.
Receiver module 711 receives resource audit response message or the resource status Indication message that Node B720 sends, and is carrying the IE that indicates Node B720 whether to have E-DPCCH power boost ability in above-mentioned message.Receiver module 711 can also be used for the IE of the instruction Node B720 ability that receives other RNC forwardings.Thus, can know whether Node B720 has E-DPCCH power boost ability.
