Abstract
The invention provides a resource allocation method, a base station and a user end. The method comprises the steps: after allocating a semi-continuous resource for the user end (UE), the base station sends a resource allocation resource to the UE by a control information channel, wherein, if confirmation information which is fed back after the UE obtains the resource allocation resource is received, the resource allocation to the UE at this time is conformed to be successful, otherwise, the resource allocation to the UE at this time is conformed to be unsuccessful. The invention can effectively solve the problem of resource waste or resource conflict as the UE has no correct decoding control channel in the continuous packet connection (CPC) technology.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of method, base station and user terminal of resource distribution.
Background technology
Along with the development of mobile communication system, the user is more and more higher to the performance requirement of mobile communication, in order to improve the communication capacity of uplink and downlink, 3rd Generation Partnership Project (3GPP, 3
RdGeneration Partnership Project) tissue has proposed high speed uplink packet access (HSUPA, High Speed Uplink Packet Access) technology and high speed downlink packet access (HSDPA, High Speed Downlink Packet Access) technology.
In HSPUA technology and HSDPA technology, the base station of network side (NodeB) need to be that user terminal (UE) distributes UE to receive or the employed resource of transmission data by control channel, wherein, the term of validity of institute's Resources allocation only has a Transmission Time Interval (TTI), and this just needs NodeB to need the Resources allocation for UE at each TTI.In order to optimize the support such as internet protocol voice technology (VoIP) class business, reduce the expense of control channel, carried out gradually the correlative study that connects (CPC, Continuous Packet Connectivity) technology to continuing grouping.In the CPC technology, NodeB can be that UE distributes semi-continuous resource by control channel, namely comprised resource continuous indication territory (RDI, Resource Duration Indicator) at control channel, can be followed successively by UE and distribute 8 or 4 continuous TTI resources.Be after UE distributes semi-continuous resource at NodeB, this semi-continuous resource is continued until that NodeB is that UE distributes new resource by control channel again, in the effective procedure of this semi-continuous resource, 1 or 3 TTI in interval between continuous 8 or 4 TTI that distributes for UE.Change by control channel at NodeB before the resource distribution of UE, the semi-continuous resource continuously effective of originally distributing, and NodeB can also be according to the service condition of UE, utilize control channel to increase or reduces the semi-continuous resource of distributing to UE, namely the resource that UE takies is reshuffled.Wherein, for the distribution of the uplink transmission resource of UE, above-mentioned control channel is for strengthening paging channel absolute grant channel (E-AGCH), and for the distribution of the downlink transfer resource of UE, above-mentioned control channel is High-Speed Shared Control Channel (HS-SCCH).
Yet, may have following problem: NodeB in the implementation procedure of above-mentioned CPC technology is after UE adjusts the resource of distributing by control channel, if UE is not correctly decoded control channel, then still can carry out transmission or the reception of data according to the resource before adjusting, and NodeB can carry out data receiver or transmission for this UE according to the resource after adjusting, and the cognitive dissonance of both sides will cause a large amount of wastings of resources or resource contention like this.Take the VoIP uplink as example, when NodeB increases to the resource of UE distribution by E-AGCH, if UE is not correctly decoded E-AGCH, then still carry out the transmission of upstream data according to the resource of originally distributing to it, NodeB then thinks and this resource is distributed to UE, and this part scheduling of resource that increases can not used to other UE, so just caused the waste of resource.When NodeB is reduced to the resource of UE distribution by E-AGCH, if UE is not correctly decoded E-AGCH, then still carry out the transmission of upstream data according to the resource of originally distributing to it, NodeB thinks that then UE has discharged the resource that partly takies, so this part resource is distributed to other UE, so just, can cause a plurality of UE to use identical resource, so that resource is used conflict.Based on similar reason, this problem also can exist with downlink transmission process in.
Summary of the invention
In view of this, the invention provides method, NodeB and UE that a kind of resource is distributed, so that avoid in the CRC technology because UE is not correctly decoded the wasting of resources or the resource conflict problem that control channel causes.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
Method provided by the invention mainly comprises: NodeB is after UE distributes semi-continuous resource, by control channel resource allocation information is sent to UE, if receive UE in the affirmation information that obtains to feed back behind this resource allocation information, confirm that then this resource to this UE is allocated successfully, otherwise, confirm that this resource to this UE distributes unsuccessfully.
The below is described in detail said method for uplink process and downlink transmission process respectively.The method flow diagram for the uplink process that Fig. 1 provides for the embodiment of the invention, as shown in Figure 1, the method can may further comprise the steps:
Step 101:NodeB after UE distributes up semi-continuous resource, sends to UE by E-AGCH with resource allocation information.
In this step, NodeB is that the UE Resources allocation can be to reduce the resource that UE takies, and perhaps increases the resource that UE takies, and also can be again namely to change the position etc. of the shared resource of UE for UE distributes diverse resource.
Step 102:NodeB judges whether to receive UE in the affirmation information that obtains to feed back behind the resource allocation information, if so, and execution in step 103, otherwise, determine that this resource is distributed unsuccessfully, process ends or re-execute step 101.
UE obtains resource allocation information if can be correctly decoded E-AGCH, then to NodeB feedback acknowledgment information after receiving E-AGCH.The mode of UE feedback acknowledgment information can adopt following several:
First kind of way: UE can pass through high-speed shared information channel (HS-SICH) feedback acknowledgment information.
In this mode, can reconfigure the timing relationship between a kind of E-AGCH and the HS-SICH, this timing relationship can be indicated at E-AGCH, and perhaps, NodeB utilizes high-level signaling to prenotice UE.After UE is correctly decoded E-AGCH, carries confirmation according to this timing relationship at HS-SICH and feed back to NodeB.This confirmation can be an indicated value of carrying in addition, for example increases in addition the indication of 1 bit; Also can be that the upper original territory of HS-SICH or a plurality of territory are set to the affirmation information that particular value identifies the UE feedback, the particular value of setting can redefine in original value, also can be the value outside original value.
The second way: UE can pass through enhanced uplink random access channel (E-RUCCH) feedback acknowledgment information.
In this mode, schedule information (the SI that UE can carry at E-RUCCH, Schedule Information) comprises confirmation in, for example, can in SI, increase the indication of 1 bit, perhaps the one or more territories among this SI are set to particular value and come identity validation information, and this particular value can redefine in original value, also can be the value outside original value.
The below lifts several particular values that adopt and comes the method for identity validation information in SI.The territory that comprises among the existing SI has: this adjacent cell path loss (SNPL of 5 bits, Serving and Neighbor Cell Pathloss) territory, UE available horsepower (the UPH of 5 bits, UE Power Headrrom) territory, strengthen the total cache occupation amount (TEBS of dedicated channel, Total E-DCH Buffer Status) territory, cache occupation amount (the HLBS of the highest priority logical channel of 4 bits, Highest priority Logical Channel Buffer Status) highest priority logical channel of territory and 4 bits sign (HLID, Highest priority Logical channel ID) territory.Can the SNPL territory, the value of in UPH territory, TEBS territory, HLBS territory and the HLID territory or the combination in any particular value that is set to preset comes identity validation information, this particular value can be 00000,11111 or other value; Also can adopt the TEBS territory be set to 0 and the HLBS territory be set to the non-zero identity validation information of coming; The implication that can also keep SNPL territory and UPH territory is constant, be set to a special domain after HLBS territory and HLID territory merged into 8 bits, adopt this special domain to come identity validation information, for example, this special domain can be divided into type (Type) territory and information (Info) territory, perhaps only be set to the Type territory, in the Type territory, identify confirmation.More preferably, can also identify according to the value in Type territory affirmation information under the different application scene.The value in this Type territory and corresponding implication can be as shown in table 1.
Table 1
| The Type value | Implication |
| 001 | UE is for the affirmation information of E-AGCH channel feedback |
| 010 | UE initiatively changes quiet period over to the NodeB indication |
| 011 | UE initiatively changes active period over to the NodeB indication |
| … | … |
The timing relationship that can redefine in addition between an E-AGCH and the E-RUCCH comes feedback acknowledgment information, UE can be according to timing relationship feedback acknowledgment information on corresponding E-RUCCH of this definition, correspondingly, if NodeB receives the confirmation message according to the timing relationship of this definition at E-RUCCH, think that then this resource is allocated successfully, otherwise think that this resource distributes unsuccessfully.
No matter NodeB still reduces the resource that UE takies by the resource that E-AGCH increase UE takies for first kind of way and the second way, perhaps again can use for UE distributes diverse resource.
The third mode: UE can be by strengthening uplink physical channel (E-PUCH) feedback acknowledgment information.
UE can send in the E-PUCH resource that arrives at first and carry the SI of confirmation after being correctly decoded E-AGCH and getting access to resource allocation information; The E-PUCH resource that this arrives at first can be that this is the resource that described UE distributes, and also can be the resource that described UE uses before this sub-distribution.Wherein, can in SI, comprise confirmation by the mode described in the second way.NodeB by E-AGCH to the UE Resources allocation after, if in setting duration, on the resource that this UE before this sub-distribution uses or in the resource of this sub-distribution, receive the SI that comprises confirmation that described UE sends, think that then this resource is allocated successfully, otherwise, think that this resource is distributed unsuccessfully.
The 4th kind of mode: UE comes implicitly feedback acknowledgment information by changing the pattern that sends data.
Because UE after being correctly decoded E-AGCH, can stop to send any packet on this sub-distribution resource before, the resource that changes in this sub-distribution sends packet.Therefore, NodeB can be by judging whether UE changes the pattern that sends data and determine whether to get access to confirmation.
If NodeB reduces the resource that UE takies by E-AGCH, then can adopt following judgment mode:
NodeB is after sending resource allocation information by E-AGCH, if in setting duration, all do not receive the packet that the resource of UE before this Resources allocation sends, can think then that pattern that UE sends data has occured to change and namely implicitly feed back confirmation, determine that this resource is allocated successfully; Otherwise, determine that this resource is distributed unsuccessfully.Setting duration wherein can be configured by high-level signaling.
NodeB is after sending resource allocation information by E-AGCH, if within the repetition period of the resource before N continuous this Resources allocation, all do not receive packet, can think then that pattern that UE sends data has occured to change and namely implicitly feed back confirmation, determine that this resource is allocated successfully; Otherwise, determine that this resource is distributed unsuccessfully.Wherein, N is default integer value.
NodeB is after sending resource allocation information by E-AGCH, if received the packet of the active period of UE transmission in the resource of this sub-distribution, then NodeB can think that the pattern of UE transmission data variation has occured namely implicitly fed back confirmation, determines that this resource is allocated successfully.Need to prove: the packet that UE sends comprises the packet of active period and the packet of quiet period, wherein, the packet of active period is larger packet, need to carry for UE distributes more resource, the volume datagram of quiet period is less packet, can carry for UE distributes less resource.
If NodeB increases the resource that UE takies by E-AGCH, then can adopt following judgment mode:
NodeB is after sending resource allocation information by E-AGCH, if in setting duration, receive the packet that UE sends in the resource of this sub-distribution, can think then that pattern that UE sends data has occured to change and namely implicitly feed back confirmation, determine that this resource is allocated successfully; Otherwise this resource is distributed unsuccessfully.Setting duration wherein can be configured by high-level signaling.
NodeB is after sending resource allocation information by E-AGCH, if within the repetition period of the resource of continuous N this sub-distribution, receive the packet that UE sends, can think then that pattern that UE sends data has occured to change and namely implicitly feed back confirmation, determine that this resource is allocated successfully; Otherwise, determine that this resource is distributed unsuccessfully.Wherein, M is default integer value.
NodeB is after sending resource allocation information by E-AGCH, if the resource before this sub-distribution receives the packet that UE sends, and comprise the SI for the more resources of request base station assigns in this packet, can think that then the pattern of UE transmission data does not change, think that UE does not have feedback acknowledgment information, confirm that this resource is distributed unsuccessfully.
Step 103:NodeB determines that this resource is allocated successfully, in the packet that this UE of resource reception of this sub-distribution sends, process ends.
The method flow diagram for downlink transmission process that Fig. 2 provides for the embodiment of the invention, as shown in Figure 2, the method can may further comprise the steps:
Step 201:NodeB sends to UE by HS-SCCH with resource allocation information after being the semi-continuous resource of UE allocation of downlink.
In this step, NodeB is that the UE Resources allocation can be to reduce the resource that UE takies, and perhaps increases the resource that UE takies, and also can be again namely to change the position etc. of the shared resource of UE for UE distributes diverse resource.
Step 202:NodeB judges whether to receive UE in the affirmation information that obtains to feed back behind the resource allocation information, if so, and execution in step 203, otherwise, determine that this resource is distributed unsuccessfully, process ends or re-execute step 201.
UE obtains resource allocation information if can be correctly decoded HS-SCCH, then to NodeB feedback acknowledgment information after receiving HS-SCCH.The mode of UE feedback acknowledgment information can adopt following several:
First kind of way: UE can pass through HS-SICH feedback acknowledgment information.
In this mode, can utilize existing timing relationship between HS-SCCH and the HS-SICH, perhaps reconfigure the timing relationship between a kind of HS-SCCH and the HS-SICH, this timing relationship can be indicated at HS-SCCH, perhaps, NodeB utilizes high-level signaling to prenotice UE.After UE is correctly decoded HS-SCCH, carries confirmation according to this timing relationship at HS-SICH and feed back to NodeB.This confirmation can be an indicated value of carrying in addition, for example increases in addition the indication of 1 bit; Also can be that the upper original territory of HS-SICH or a plurality of territory are set to the affirmation information that particular value identifies the UE feedback, the particular value of setting can redefine in original value, also can be the value outside original value.
The second way: UE can pass through E-RUCCH feedback acknowledgment information.
In this mode, UE can comprise confirmation in the SI that E-RUCCH carries, for example, can in SI, increase the indication of 1 bit, perhaps the one or more territories among this SI are set to particular value and come identity validation information, this particular value can redefine in original value, also can be the value outside original value.
Concrete how to adopt particular value among the SI to come identity validation information can adopt mode described in the middle second way of mentioning embodiment illustrated in fig. 1, do not repeat them here.
In addition, the timing relationship that also can redefine between a HS-SCCH and the E-RUCCH comes feedback acknowledgment information, UE can be according to timing relationship feedback acknowledgment information on corresponding E-RUCCH of this definition, correspondingly, if NodeB receives the confirmation message according to the timing relationship of this definition at E-RUCCH, think that then this resource is allocated successfully, otherwise think that this resource distributes unsuccessfully.
No matter NodeB still reduces the resource that UE takies by the resource that HS-SCCH increase UE takies for first kind of way and the second way, perhaps again can use for UE distributes diverse resource.
Step 203:NodeB determines that this resource is allocated successfully, and sends data, process ends to this UE on the resource of this sub-distribution.
