Table 1
(High Speed Packet Access Evolution in research HSPA+), still needs to utilize the HSUPA technology to carry out up enhancing to insert evolution in high-speed packet.In order to satisfy some professional service quality (Quality of Service, QoS) demand and business characteristic, scheme that this RDI method of salary distribution is expanded has been proposed, be that the base station is by sending E-AGCH one time, for UE distributes permanently effective E-DCH physical uplink channel (E-DCH Physical Uplink Channel, E-PUCH) physical resource has been saved signaling consumption.
HSUPA is divided into scheduled transmission and non-scheduled transmission, and the flow process of scheduled transmission comprises the steps: as shown in Figure 1
Have uplink strengthening data etc. to be sent in the step 101:UE buffer memory, UE to base station (Node B) send E-DCH insert at random ascending control channel (E-DCH Random access Uplink ControlChannel, E-RUCCH), the request scheduling resource;
Step 102:Node B carries out scheduling of resource according to the dispatch request information of receiving, and (E-DCH Absolute Grant Channel E-AGCH) goes up to UE transmission resource authorization information in the E-DCH absolute grant channel;
Step 103:UE is according to the resource authorization information of receiving, strengthening transformat combination (E-TFC) selects, select suitable transmission block size (Transport Block Size, TBS) and modulation system, encode afterwards, modulate, (E-DCH PhysicalUplink Channel E-PUCH) goes up to Node B transmission uplink strengthening data at E-DCH physical uplink channel;
Step 104:Node B receives after the E-PUCH, carry out decoding processing, obtain the feedback information (ACK/NACK) of positive or negative according to Cyclic Redundancy Check, being mapped to E-DCH after the coding mixes automatic repeat requests answering indication signal channel (E-DCH HARQ acknowledgeIndicator Channel feeds back to this UE on E-HICH).
Like this, the uplink strengthening data that UE has just finished a scheduled transmission process sends, certainly according to the mechanism of mixing automatic repeat requests (HARQ), if the feedback information that UE receives is the feedback information (NACK) negating, then UE need retransmit this packet, till receiving asserts feedback information or reaching maximum retransmission.In this process, the buffer memory that important references information be UE of base station when scheduling distributes physical resource.When UE did not obtain the E-PUCH physical resource of base station assigns, schedule information (SI) was placed on and sends to the base station among the E-RUCCH; Obtain the E-PUCH physical resource of base station assigns as UE after, SI is placed in the media access control protocol protocol Data Unit (MAC-e PDU), sends to the base station on E-PUCH.The buffer status information that SI comprises comprises:
Total E-DCH buffer status (TEBS), length is 5bits, is used to represent the data total amount of all logic channels of terminal, comprises that (TEBS is a quantized value for Radio Link Control, RLC) the to be transmitted or data volume that retransmits such as layer for Radio Link control.
Highest priority logical channel buffer status (HLBS), length are 4bits, the data total amount of expression highest priority logical channel, and HLBS is a relative ratio with respect to TEBS;
Highest priority logical channel sign (HLID), length is 4bits; Indication has the logic channel of limit priority to be sent such as data; If have the logic channel of a plurality of limit priorities to exist simultaneously, select the Logic Channel Identifier (ID) of buffer memory occupation proportion maximum to report so;
Node B carries out scheduling of resource according to the dispatch request information of receiving, and sends resource authorization information on E-AGCH.The information of E-AGCH channel bearing comprises:
Power resource relevant information (PRRI), length are 5bits, and expression Node B dispatches the power resource mandate to UE;
Sign indicating number resource related information (CRRI), length is 5bits, the spreading code that indication E-PUCH uses;
Time interval resource relevant information (TRRI), length are 5bits, and 5 bits indicate time slot 1 to time slot 5 respectively;
Resource continuous indication (RDI), length is 3bits, is used to the TTI number and the interval information of indicating resource authorization to come into force;
E-AGCH cyclic sequence number (ECSN), length is 3bits, is used for the auxiliary E-AGCH exterior ring power control of carrying out, the Block Error Rate (BLER) of statistics E-AGCH.
The E-HICH indication, length is 2bits, is used to indicate the E-HICH of bearing downlink feedback information;
The indication of E-UCCH number, length is 3bits, the E-UCCH number that expression sends mostly is 8 most.
Adopting the base station is the mode that UE distributes duration or permanently effective physical resource, needs the base station can comparatively accurately must know the outgoing data amount of UE.Yet schedule information (SI) based on prior art, the buffer memory that UE is total and the buffer memory of highest priority logical channel can only be known in the base station, and SI is a quantized value, and granularity is bigger, the base station is difficult to by the more accurate outgoing data amount that must know UE of existing SI, thereby cause the scheduling of base station dispatcher inaccurate, make scheduling resource and UE resource requirement not match.Will cause following adverse consequences like this:
If Resources allocation is superfluous or distribute the situation of permanently effective resource; when the UE transfer of data finishes or does not have more upstream data and need transmit; can not in time discharge the shared up public resource of this UE; thereby can not in time use to other UE this scheduling of resource, cause the waste of up public resource.

Embodiment
The present invention is directed to the base station is that the UE distribution has the scheduling of resource mode of certain duration or permanently effective physical resource, corresponding method for releasing resource is provided, can be after being the UE Resources allocation, carry out resource according to the outgoing data amount of UE reality and discharge, thereby improve the utilance of resource and the flexibility of scheduling.Specifically, method for releasing resource of the present invention comprises two kinds of implementations, and a kind of is the explicit resource method for releasing, and when UE confirmed not have data to transmit, UE sent the request that discharges resource to Node B; Node B notifies UE to carry out the release of resource by the mode that sends explicit physical layer signaling after receiving described request; Another kind is the implicit expression method for releasing resource, when the UE free of data need be transmitted, carries out resource by the implicit expression agreement of UE side and Node B side and discharges.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is further elaborated below in conjunction with accompanying drawing.
Embodiment one: the explicit resource method for releasing
The basic realization flow of present embodiment is after the UE distribution has certain duration or permanently effective physical resource, to carry out following flow process in the base station as shown in Figure 2:
Step 201:UE side is in the asserts feedback message (ACK) of receiving all protocol Data Unit PDU that sent or after arriving maximum retransmission, judge whether to also have (comprising new data and data retransmission) to be sent such as data, if then execution in step 202, otherwise, execution in step 203.
Step 202: continue to use original resource transmission upstream data.If Node B received the up MAC-e PDU new data that carries high level data before discharging resource, think that then this resource continues as former UE and uses, and go to step 201.
Step 203:UE sends to Node B and discharges resource request, and in the present embodiment, this request is the MAC-e PDU of the continuous only carrying SI (TEBS is set to 0) that sends.
Step 204: after Node B side is received the individual MAC-e PDU that only carries SI (TEBS=0) of M (M is configurable) continuously, trigger the resource releasing mechanism, by the explicit notice UE release physical resource of mode of transmission physical layer signaling, and discharge the physical resource of self distributing to described UE.
Step 205: when UE receives this physical layer signaling, release physical resource immediately.
In addition, if UE has new data to wait to send out, then initiate random access procedure again after resource discharges.
The physical layer signaling indication that Node B notice UE discharges resource has following several:
(1) notify by E-AGCH, concrete mode comprises:
1. notification field is TRRI, and TRRI is set to " 0 " entirely, and expression does not discharge for UE distributes any time interval resource indexed resource.
2. notification field is CRRI.In low spreading rate time division duplex (LCR TDD), this field is 5 bits, represents 32 values altogether, but has only used index 0...30 totally 31 values in the system at present, therefore can use " 11111 ", and promptly index 31 discharges indication as resource.
3. notification field is PRRI.This field is 5 bits, represents 32 values altogether, and the implication that can revise one of them index value is used for indexed resource and discharges, and for example revises last high value index 31, the i.e. implication of " 11111 ".
4. extra 1 bit information that increases discharges indication as resource on E-AGCH.
5. notification field is any one or a combination in any of above-mentioned special field.
(2) (High Speed Shared Control Channel HS-SCCH) notifies by downlink high-speed shared control channel.The control information of the last carrying of HS-SCCH sees Table 2.
1. notification field is a gap information, gap information is changed to " 00000 ", and expression does not discharge for UE distributes any time interval resource indexed resource.
2. notification field is the special pattern of initial code (Start Code) and stop code (Stop Code) part.In the code channel field of 8 bits, preceding 4 bits are represented position, initial code road in the present system, and back 4 bits are represented position, stop code road, and initial code must be smaller or equal to stop code (except " 11110001 ", the employed spreading factor SF=1 of its expression HS-PDSCH).Therefore can use initial code to discharge for example " 11110000 " or " 11110010 " or the like greater than a particular bit pattern of stop code indexed resource.
3. extra 1 bit information that increases discharges indication as resource on HS-SCCH.
4. notification field is any one or a combination in any of above-mentioned special field.
Table 2
Embodiment two: the implicit expression method for releasing resource
A kind of implicit expression resource release flow of present embodiment as shown in Figure 3, wherein the processing procedure of UE side comprises the steps: shown in Fig. 3 a
The processing procedure of Node B side comprises shown in Fig. 3 b:
In addition, if UE has data to wait to send out then initiates access at random again after resource discharges.
The implicit expression method for releasing resource can also adopt flow process as shown in Figure 4, comprising:
Step 401:UE side has judged whether (comprising new data and re-transmission) to be sent such as data after the ACK that receives all PDU that sent confirms or arrives maximum retransmission, if then execution in step 403, otherwise execution in step 402.
Step 402:UE sends the individual MAC-ePDU that only carries SI (TEBS=0) of M (M is configurable) continuously, triggers the resource releasing mechanism.Following two kinds of resource delivery modes are arranged:
1. after UE sends M continuously and only carries the PDU of SI (TEBS=0), directly discharge resource.Node B side discharges resource after receiving that continuously M only carries the PDU of SI (TEBS=0).
2. after UE sends M continuously and only carries the PDU of SI (TEBS=0), wait for the affirmation of Node B to these packets, after the ACK that receives these packets confirmed or arrives maximum retransmission, UE discharged resource.Node B side discharges resource after M packet being carried out the ACK affirmation or arriving maximum retransmission.
During UE sends M continuously and only carries the PDU of SI (TEBS=0),, then go to step 403 if there is new data to wait to send out.
Step 403:UE had new data to wait to send out before resource discharges, and then continued to use original resource to transmit.If Node B received up new data before discharging resource, think that then this resource continues as former UE and uses.
In addition, if UE has data to wait to send out then the access at random of initiation again after resource discharges.
