Description

A kind of TTI switching method, base station and user equipment

Technical field

The present invention relates to field of communication technology, in particular to a kind of TTI switching method, base station and user equipment.

Background technique

With the rapid development of the communication technology, WCDMA (Wideband Code Division Multiple Access, Wideband code division multiple access) one of mainstream technology as 3-G (Generation Three mobile communication system), it has obtained widely grinding in the world Study carefully and applies.In the Rel- that 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Program) is formulated DCH channel, referred to as R99DCH, the covering that R99DCH channel has had are introduced in 99 versions, but can only improve lesser data speed Rate.HSUPA (High-Speed Uplink Packet Access, high speed uplink are introduced in the Rel-6 version that 3GPP is formulated Link packet access) technology, introduced transmission channel is E-DCH (Enhanced Dedicated in HSUPA Channel, uplink enhancing).E-DCH includes two kinds of transmission intercal (Transmission Time Interval, TTI) types, 2ms TTI and 10ms TTI, wherein 2ms TTI is capable of providing high message transmission rate and small propagation delay time；10ms TTI It is capable of providing better covering.Therefore cell edge is moved to from center of housing estate as user equipment (User Equipment, UE) When in order to obtain better covering, it is necessary to be switched to 10ms TTI from 2ms TTI；Correspondingly, when UE is mobile from cell edge When to center of housing estate, in order to obtain higher peak rate, it is necessary to be switched to 2ms TTI from 10ms TTI.

In addition, the covering of R99DCH is greater than E-DCH 10msTTI, so when UE is moved to cell edge, even if UE works as Before use E-DCH 10msTTI, it is possible to covering still there is problem, need for UE to be switched to from E-DCH 10msTTI The corresponding TTI of DCH.

In the prior art, E-DCH TTI switching includes two aspects: the execution of covering measurement and E-DCH TTI switching Process.

It is covering measurement first, UPH is reported to base by SI (Scheduling Information, scheduling information) by UE It stands, wherein UPH (UE transmission power headroom, UE transmission power surplus), UPH is maximum UE transmission power With DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel) power ratio.Usual UPH Lower than a thresholding, then it is assumed that covering is limited or UE is moved to cell edge, in order to obtain better covering, needs to configure 10ms TTI；UPH is higher than a thresholding, then it is assumed that UE is moved to center of housing estate, in order to obtain higher peak rate, needs to configure as 2ms TTI。

The execution process of followed by TTI switching, in the prior art, the execution process of E-DCH TTI switching synchronize weight With with two methods of asynchronous reconfiguration, synchronous reconfiguration refer to base station controller (Radio Network Control, RNC) respectively to The CFN (Connection Frame Number, Connection Frame Number) of UE and base station configuration TTI switching, UE switch in specified CFN The E-DCH data sent to target TTI type, base station in specified CFN according to target TTI type parsing UE.

It please refers to shown in Fig. 1, for the flow chart of synchronous reconfiguration, which includes:

Firstly, RNC, which is determined, executes TTI switching, then RNC sends RRC (Radio Resource Control, nothing to UE Line resources control) signaling, for example RADIO BEARER RECONFIGURATION REQUEST (radio bearer reconfiguration request) refers to Show that UE is switched to target TTI type, wherein include activationary time (Activation time) in radio bearer reconfiguration request, swash Live time can for example be indicated with CFN.RNC sends RADIO LINK RECONFIGURATION to base station (such as NodeB) PREPARE (wireless link reconfigured preparation) message carries new configuration in the message, including TTI type；Then base station to RNC sends response message (RADIO LINK RECONFIGURATION Ready, wireless link reconfigured preliminary message), then RNC sends Radio Link Reconfiguration Confirm (wireless link reconfigured confirmation) message to base station again, wherein It is wirelessly connected in reconfiguration confirmation message and carries activationary time, such as also indicated with CFN, which is used to indicate base station and is referring to Fixed activationary time parses upstream data according to target TTI.Subsequently, UE sends RADIO BEARER RECONFIGURATION RESPONSE (radio bearer reconfiguration response) message is to RNC.

And the process of asynchronous reconfiguration is similar with the process of synchronous reconfiguration, does not specify activationary time in the message only, UE connects Receive it is as early as possible after reconfiguration request be switched to target TTI, base station be also it is same, it is as early as possible to utilize new TTI parsing Upstream data, details are not described herein for detailed process.

However, the present inventor has found during realizing the technical solution in the embodiment of the present invention, in existing synchronization During reconfiguration, RNC notifies UE to execute TTI and switch by RRC signaling, while being sent out by wireless link reconfigured process to base station New configuration information is sent, needs at least to carry out 3 Signalling exchanges between RNC and base station, TTI switching could be completed, so in this way Handover mechanism will lead to TTI switching not in time, have a biggish time delay, especially when switching from 2msTTI to 10msTTI, this The time delay of sample will lead to E-DCH loss of data even call drop.And for the mode of asynchronous reconfiguration, base station cannot accurately determine that UE is cut The opportunity for changing to target TTI after receiving the reconfiguration signaling that RNC is sent, needs to attempt solution according to switching both front and back TTI type Analysis, so the hardware resource of waste base station.

In the specific implementation process, step 101 specifically: user equipment receives the first TTI corresponding first that RNC is sent Configuration information and corresponding second configuration information of the 2nd TTI.Wherein, RNC can send the first TTI to UE by dedicated RRC signaling Resource allocation information corresponding with the 2nd TTI.It should be noted that the first configuration information and the second configuration information can be with Be it is predefined, that is, do not need RNC configuration, the preferential method for selecting RNC configuration, so the present invention is situated between so that RNC is configured as an example It continues.

In practice, RNC can be to the process that UE sends the first configuration information and the second configuration information and meanwhile, May not be at the same, correspondingly, in a step 101, UE receives the corresponding configuration information of the first TTI and receives the 2nd TTI Corresponding second configuration information can be and meanwhile, may not be at the same.

First, it is assumed that the first TTI is 2msTTI, the 2nd TTI is 10msTTI, for example, after Initial R RC connection foundation, RNC gives UE with regard to prewired 10msTTI information (it is assumed that the current TTI of UE is 2msTTI).

For another example RNC based on 6a event come the prewired 10msTTI information of decision (it is assumed that the current TTI of UE is 2msTTI) give UE, wherein 6a event refer to the total transmission power of UE be greater than preset threshold value, then UE just report it is total Transmission power is to RNC, then RNC can need prewired 10msTTI information to UE according to 6a event decision.

In a further embodiment, when RNC sends the first configuration information and the second configuration information to UE at the same time, together When also specified UE currently used TTI type, in general, call drop, RNC can specify UE currently used in order to prevent TTI is 10msTTI.

Further, in the first configuration information and the second configuration information that RNC is sent, each TTI corresponding one is separately included Enhanced-DedicatedChannel Media access contorl stream (E-DCH MAC-d flow) parameter is covered, for example, being based on E-DCH MAC-d flow The E-DCH MAC-d flow maximum number of of Identity (Enhanced-DedicatedChannel MAC-d traffic identifier) configuration Retransmissions (Enhanced-DedicatedChannel MAC-d flows maximum retransmission), ACK (positive confirmation) power bias NACK are (negative true Recognize) power bias or E-DPCCH/DPCCH power offset (power bias of data channel and control channel)；First TTI Corresponding first E-DCH MAC-d flow parameter, the second configuration information include the corresponding 2nd E-DCH MAC-d of the 2nd TTI Flow parameter；It further, can also include other parameters, a set of DTX is respectively configured in for example, the first TTI and the 2nd TTI (Discontinuous Transmission, discontinuous send) parameter and/or DRX (Discontinuous Reception, It is discontinuous to receive) parameter, the application is not construed as limiting.

Further, the first configuration information and/or the second configuration information further include but are not limited to use in determining send comprising TTI The power of the control channel of switching instruction confirmation message.TTI switching instruction confirmation message is used to refer to user equipment and has received Indication message.

Preferably, in another embodiment, before step 101, UE also reports the ability for supporting TTI to switch to refer to RNC Show that information, such as UE can report this in RRC CONNECTION SETUP COMPLETE (RRC connection, which is established, to be completed) message Capability indication information.

Step 102: user equipment receives the indication message that base station is sent.

Preferably, base station is to notify UE to execute TTI switching by physical signaling, such as notify by HS-SCCH order UE executes TTI switching.Certainly, in practical applications, can also be sent by other physical signaling or non-physical signaling to UE Indication message.About base station, how when decision sends indication message, and sends which type of switching instruction letter Breath, and how using High-Speed Shared Control Channel instruction (HS-SCCH order) indication message is sent, this part will be When the specific embodiment of subsequent descriptions base station side, it is described in detail.

It should be noted that switching instruction can serve to indicate that UE is switched between R99DCH and E-DCH, but this Invention is introduced for switching between E-DCH TTI.

Step 103: current TTI is switched to target TTI corresponding with indication message by user equipment, wherein target TTI is the first TTI or the 2nd TTI.I.e. if the TTI of user equipment is the first TTI before the handover, target TTI is the Two TTI, and if the TTI of user equipment is the 2nd TTI before the handover, target TTI is the first TTI.

Step 104: user equipment sends data to base station with target TTI.

For example, it is assumed that the first TTI is 2msTTI, the 2nd TTI is 10msTTI, and the TTI of user equipment is before switching 2msTTI, then target TTI is just 10msTTI, then step 104 is specifically, send upstream data to base station with 10msTTI.

In practical applications, specifically there are many implementation forms for step 104, which will be described in detail later.

Through the above steps as can be seen that because user equipment can receive the corresponding with confidence of different TTI difference first Breath, then after the indication message for receiving base station transmission, so that it may directly be cut to the current TTI of user equipment It changes, and switches to target TTI corresponding with indication message, and base station is sent data to target TTI, so not needing During switching, RNC sends new configuration information to base station again, so also multiple there is no need to carry out between RNC and base station Signalling exchange, so the TTI handoff procedure in the present embodiment is timely, time delay is smaller, so avoiding in 2msTTI to 10msTTI When switching, E-DCH loss of data or call drop, simultaneously as switching of the 10msTTI to 2msTTI can be executed in time, so can Improve peak rate.

In the specific implementation process, after step 102, user equipment does not send confirmation message to base station, and base station can lead to It crosses repeating transmission indication message and guarantees that user equipment receives, it specifically can be by the way that the period retransmitted or sending times, example be arranged Continuous retransmission indication message or continuous retransmission 3 times such as in 1s.And user equipment receive indication message it Afterwards, step 103 and step 104 are just and then executed, correspondingly, base station just uses two sets after distributing indication message under Resource uses 2msTTI and 10msTTI to parse the E-DCH upstream data that user equipment is sent respectively.

But in another embodiment, after step 102, before step 104, which further includes step 105: being used Family equipment sends confirmation message to base station, and indication message is had received or do not received with signals base user equipment.

Wherein, the first embodiment of step 105, user equipment feeding back ACK (Acknowledgment just confirms) letter Breath or NACK (Negative Acknowledge negative acknowledgment) information are to base station.If having correctly received indication message, that User equipment just sends ACK information to base station, if being not properly received indication message, user equipment is just sent Nack message is to base station.

Second of embodiment of step 105, user equipment carry the E-TFCI (E-DCH being forbidden to use in E-DPCCH Transport Format Combination Indicator, enhancing dedicated transmission channel format merge instruction) it indicates to use Family equipment has been received by indication message, wherein the E-TFCI being forbidden to use is predefined configurable or reserved.Example It can such as be configured by RNC, for example (Transport Block Size, transmission block are big using 2ms TTI E-DCH TBS It is small) E-TFCI being forbidden to use in table.The E-TFCI is reserved for another example, it is impossible to be used in normal data transmission is only used Indication message is properly received in instruction user.

The third embodiment of step 105, user equipment is with the corresponding UL of target TTI (Uplink, uplink) scrambling code hair Data or control information are sent, indication message is correctly received with instruction.Such as match in RNC to user equipment prewired first When confidence breath and the second configuration information, respectively two TTI configure two scrambling codes SC1 and SC2；It is cut with 2msTTI to 10msTTI It is changed to example, after UE is properly received HS-SCCH order, uplink DPCCH is sent with SC2, after base station detects, uses target TTI parses E-DCH.For serving BS, under distribute just need after HS-SCCH order respectively using two sets of resources respectively by Parsing uplink DPCCH is attempted according to SC1 and SC2.

4th kind of embodiment of step 105, user equipment indicate user equipment just using the domain information in DPCCH Really receive indication message.For example the corresponding bit of FBI (feedback information, feedback information) can be used Position indicates.

5th kind of embodiment of step 105, user equipment send individually carrying non-zero transmission channel format merging and refer to Show the physical control channel (DPCCH) of (TFCI) to indicate that user equipment has been received by indication message, wherein non-zero TFCI is Predefined or configurable.

Such as when all business of user equipment are all carried on E-DCH, and currently used TTI type is E-DCH 10ms, at this moment the domain TFCI is 0 in DPCCH；(E-DCH10ms TTI is switched to DCH 10ms after UE receives indication message The indication message of TTI), then it sends and carries the DPCCH of non-zero TFCI individually to indicate that UE receives indication message；Phase The base station answered detects that the TFCI in the DPCCH is nonzero value, then it is assumed that UE is properly received indication message, non-zero TFCI It is predefined or configurable.It should be noted that independent transmission mentioned here refers to that DPCCH channel is individually sent, not The channel of adjoint Dedicated Physical Data Channel (DPDCH) is sent.

6th kind of embodiment of step 105, in this example, it is assumed that user equipment is in the switching for receiving base station transmission It before indicating information, further include that user equipment also sends power headroom (UPH) to base station, such as when the UPH of user equipment is lower than First thresholding, then user equipment reports UPH to base station.

In the present embodiment, step 105 specifically: when the current TTI of user equipment is E-DCH 2ms TTI, and use The UPH value that family equipment is sent is less than first threshold, then user equipment sends carrying the first enhancing dedicated transmission channel format and merges The enhancing Dedicated Physical Control Channel (E-DPCCH) of (E-TFCI) is indicated, to indicate that user equipment has received switching instruction letter Breath, the first E-TFCI is predefined or configurable；Alternatively,

When current TTI is 10ms TTI, and user equipment is sent to the UPH value of base station and is greater than second threshold, then user Equipment, which is sent, carries the enhancing Dedicated Physical Control Channel (E- that the second enhancing dedicated transmission channel format merges instruction (E-TFCI) DPCCH), to indicate that user equipment has received indication message, the 2nd E-TFCI is predefined or configurable.

When the currently used TTI type of user equipment be E-DCH 2ms TTI, and user equipment send UPH value it is small In first threshold, then user equipment sends and carries after receiving E-DCH 2ms and being switched to the indication message of 10ms TTI The E-DPCCH of first E-TFCI has received indication message with instruction, and the first E-TFCI is predefined or configurable 's；It should be noted that then illustrating that user is in power limited or covering constrained state, at this moment not when UPH is less than first threshold Higher speed rates E-DCH data may be used, i.e., it is generally acknowledged that at this moment E-TFCI value is smaller；So when UE receives E-DCH After 2ms is switched to the indication message of 10ms TTI, the E- for carrying the first E-TFCI (the first E-TFCI value is larger) is sent DPCCH, so that it may indicate that the base station UE is properly received indication message.It is switched to correspondingly, base station has sent E-DCH 2ms After the indication message of 10ms TTI, the E-DPCCH channel for carrying the E-TFCI (i.e. the first E-TFCI) of the larger value is detected, Then think that UE receives the TTI indication message that E-DCH 2ms is switched to 10ms.Here the first E-TFCI can be used for E- The transmission of DCH data, only when UPH is less than first threshold, UE does not select the first E-TFCI to transmit for E-DCH data, institute The indication message of base station transmission can be indicated to receive with the first E-TFCI with UE.

When the currently used TTI type of user equipment be E-DCH 10ms TTI, and user equipment send UPH value it is big In second threshold, then after user equipment receives indication message, the E-DPCCH of the 2nd E-TFCI of carrying of transmission, to refer to Show and have received indication message, the 2nd E-TFCI is predefined or configurable.It should be noted that when UPH is greater than Second threshold then illustrates that user is in cell near point or midpoint, at this moment can not use lesser speed rates E-DCH number According to that is, it is generally acknowledged that at this moment E-TFCI value is larger；After UE, which receives E-DCH 10ms, is switched to the TTI indication message of 2ms, Send the E-DPCCH for carrying the 2nd E-TFCI (the 2nd E-TFCI value is smaller, less than the first E-TFCI).Correspondingly, base station is sent out After having sent E-DCH 10ms to be switched to the TTI indication message of 2ms, the E-DPCCH for carrying the E-TFCI of smaller value is detected Channel, then it is assumed that UE receives the TTI handover request that E-DCH 10ms is switched to 2ms.

In addition, regardless of step 105 sends confirmation message, user to base station in a manner of which kind of in above-mentioned four kinds of embodiments Equipment sends confirmation message to base station receiving in the maximum time after the indication message, wherein maximum time is It is predefined or configurable.Such as soon as RNC is to user device configuration maximum time, then user equipment is in the maximum In to base station feedback confirmation message.

Next, will be described in the specific implementation process of step 104, firstly, for the opportunity that step 104 executes, If target TTI is the first TTI, when for example, 2msTTI, when user equipment sends data to base station with the first TTI, Yong Hushe Standby to send data to base station with the first TTI after having sent the lower M subframe after confirmation message, wherein M is predefined or can Configuration, M is the integer more than or equal to zero；And if target TTI is the 2nd TTI, such as when 10msTTI, user equipment is with the When two TTI send data to base station, user equipment sends data with the 2nd TTI after N number of CFN in the case where having sent after confirmation message To base station, wherein N is predefined or configurable, and N is the integer more than or equal to zero.

Wherein, M and N is configurable, e.g. by RNC to user device configuration, is predefined as fixing in the protocol Value.

Secondly, specifically there are many embodiments for step 104 to the difference of the processing mode in user face.

Wherein, the first embodiment of step 104, first before step 104, user equipment removes HARQ Data in (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) buffer area；User equipment resetting Uplink enhances (MAC-i/is) entity.Wherein, MAC-i/is entity is reset, specific is, for example, by the variable TSN of MAC layer (Transmission Sequence Number, transmit Sequence Number) resets to 0.Meanwhile because data being emptied in MAC layer , then RLC (Radio Link Control, wireless spread-spectrum technology) layer of user equipment side does not just receive network side transmission RLC ACK and retransmitted then uplink enhancing protocol Data Unit (MAC-i PDU) will be rebuild in the buffer area RLC MAC-is/MAC-i PDU, that is, perform step 104.

Being sorted simultaneously in order to avoid the side RNC MAC-is according to TSN, it is out-of-order to occur, and needs in E-DCH FP (Frame Protocol, Frame Protocol) or signaling in carry uplink enhancing entity resetting (MAC-is Reset) instruction or uplink enhance entity Reset (MAC-i/is Reset) instruction.

Second of embodiment of step 104, user equipment delete the TTI corresponding first before not sent successful switching Uplink enhances protocol Data Unit (MAC-i PDU)；User equipment constructs the corresponding 2nd MAC-i PDU of target TTI, wherein In the 2nd MAC-i PDU and in the first MAC-i PDU, payload is identical；User equipment sends target TTI corresponding the Two MAC-i PDU.

TTI as shown in figure 3, in the present embodiment, such as before switching is 2msTTI, then target TTI is 10msTTI, then just will the corresponding MAC-i PDU deletion of not sent successful 2ms TTI, it is corresponding to be configured to 10ms TTI MAC-i PDU, but payload is kept as 2msTTI, but in order to match 10ms TTI TBS table, is needed wherein Fill out padding bit (filler).As long as shown in figure 3, retransmitting the MAC-i PDU of TSN=2, it is assumed that effective load of 2msTTI Lotus is 160bit, but in order to match the TBS table of 10msTTI, it is assumed that the load of the TBS table of 10msTTI is 166bit, So just in the 2nd MAC-i PDU filler, i.e. 6bit, but payload or 160bit.

TSN is not reset simultaneously, consistent when keeping with 2msTTI.Therefore, in the present embodiment, triggering rlc layer is not needed It retransmits.

The third embodiment of step 104, user equipment are corresponding by the TTI before not sent successful switching in physical layer The first data encoding be corresponding second data of target TTI；User equipment sends the second data.

I.e. in the present embodiment, the MAC-i PDU of not sent successful 2msTTI is not deleted, but passes through volume in physical layer Code is written to 10msTTI, and it is with identical TBS table that this method, which requires the first TTI and the 2nd TTI,.

TSN is not reset simultaneously, consistent when keeping with 2msTTI.Method in the present embodiment does not need triggering rlc layer and retransmits.

4th kind of embodiment of step 104, after user equipment receives indication message, does not remove HARQ buffer In data, by the data in HARQ buffer according to target TTI type construct MAC-i PDU, be sent to base station；And again MAC-i/is entity is set, TSN is reset to 0.Being sorted simultaneously in order to avoid the side RNC MAC-is according to TSN, it is out-of-order to occur, and needs MAC-is reset instruction is carried in E-DCH FP (Frame Protocol, Frame Protocol) or signaling or MAC-i/is reset refers to Show.

In another embodiment, user equipment is after receiving indication message, to the processing mode in user face are as follows: receives To after indication message, new MAC-i PDU is not constructed, while not removing the data in existing harq buffer area；When When having the data end of transmission in harq buffer area, user equipment sends the confirmation message to the indication message；User sets Standby next CFN after having sent confirmation message is switched to 10msTTI；Next CFN of the base station after receiving confirmation message Think to be switched to 10msTTI.I.e. as described previously, user equipment side is predefined or is configured with a maximum time, at this In maximum time, user equipment within maximum time by the data end of transmission in harq buffer area, retransmit confirmation message to Base station.

Embodiment two

In the present embodiment, TTI switching method will be described from base station side, will be please referred to shown in Fig. 4, this method packet It includes:

Step 201: base station receives corresponding first configuration information of the first TTI and corresponding second configuration information of the 2nd TTI.

In the specific implementation process, step 201 specifically: base station receives corresponding first configuration of the first TTI that RNC is sent Information and corresponding second configuration information of the 2nd TTI.Wherein, RNC can send first to base station by wireless link reconfigured process TTI and the corresponding resource allocation information of the 2nd TTI.

Further, step 201 is similar with step 101, and RNC sends the first configuration information and the second configuration information to base station Process can be and meanwhile, may not be at the same, detailed process please refers to the description to step 101, no longer superfluous herein It states.

In a further embodiment, when RNC sends the first configuration information and the second configuration information to base station at the same time, Also specified UE currently used TTI type simultaneously, in general, call drop, RNC can specify UE currently used in order to prevent TTI is 10msTTI.

Further, in the first configuration information and the second configuration information that RNC is sent, each TTI corresponding one is separately included Cover E-DCH MAC-d flow parameter, the i.e. corresponding first E-DCH MAC-d flow parameter of the first TTI, the second configuration information packet Include the corresponding 2nd E-DCH MAC-d flow parameter of the 2nd TTI；Further, can also include other parameters, for example, first TTI and the 2nd TTI be respectively configured a set of DTX (Discontinuous Transmission, discontinuous send) parameter and/or DRX (Discontinuous Reception, discontinuous to receive) parameter, the application are not construed as limiting.

Further, the first configuration information and/or the second configuration information include but is not limited to be used to determine that user equipment to be sent Switch the power of the control channel of instruction confirmation message comprising TTI；Wherein, TTI switching instruction confirmation message is used to refer to user Equipment has received indication message.

Preferably, in another embodiment, before step 201, base station also reports the ability for supporting TTI to switch to RNC Indicate that information, such as base station can report the capability indication information in Audit Response (audit response) message.

Step 202: base station sends the indication message that TTI switches to user equipment, so that user equipment is able to carry out Step 103.

In the specific implementation process, base station notifies UE to execute TTI switching by physical signaling, such as passes through HS-SCCH Order notifies UE to execute TTI switching.Certainly, in practical applications, other physical signaling or non-physical signaling can also be passed through Indication message is sent to UE.

As shown in Table 1, the HS-SCCH order combination currently to have used:

Table one

Xeodt1 as can be seen from Table I, Xeodt2 are 11 and Xodt1, Xodt2, Xodt3 are 010 (or 011,100 Deng) may be used as TTI switching indication message.

Further, it is preferred that the HS-SCCH order can be small by the service E-DCH of user equipment in E-DCH RLS set Area's triggering.

In the specific implementation process, before step 202, this method further include: base station judges whether user equipment needs TTI switching is carried out, the first judging result is obtained；When the first judging result indicates that user equipment needs to carry out TTI switching, base station Generate indication message.

In practice, whether base station decision user equipment needs to carry out TTI switching, can be real in several ways It is existing.

First embodiment is judged as whether UPH is lower than first if the current TTI of user equipment is 2msTTI Whether thresholding and/or upstream data rate (or E-TFCI of current TTI user equipment selection) are lower than the second thresholding, if UPH It is lower than the second thresholding lower than the first thresholding and/or upstream data rate (or E-TFCI of current TTI user equipment selection), that It means that user equipment needs to carry out TTI switching, and is the switching for triggering 2msTTI to 10msTTI.

Second embodiment, if the current TTI of user equipment is 2msTTI, base station just count in Y TTI whether There is the UPH of user equipment to report in X TTI to be below third thresholding, wherein Y, N are the integer more than or equal to 1, and X is less than etc. In Y；And/or whether upstream data rate (or E-TFCI of current TTI user equipment selection) is lower than the second thresholding；If Y Having the UPH of user equipment to report in X TTI to be below third thresholding and/or upstream data rate in TTI, (or current TTI is used The E-TFCI of family equipment selection) it is lower than the second thresholding, it then meaning that user equipment needs to carry out TTI switching, and is triggering The switching of 2msTTI to 10msTTI.

Wherein, in above two embodiment, the first thresholding and third thresholding be may be the same or different.

Third embodiment is judged as whether UPH is higher than the 4th if the current TTI of user equipment is 10msTTI Whether the TEBS (buffer size) of thresholding and/or user equipment to report is higher than the 5th thresholding, if UPH is higher than the 4th thresholding, And/or the TEBS of user equipment to report is higher than the 5th thresholding, then meaning that user equipment needs to carry out TTI switching, and is Trigger the switching of 10msTTI to 2msTTI.

4th embodiment, if the current TTI of user equipment is 10msTTI, base station count in S TTI whether There is the UPH of user equipment to report in P TTI to be above the 6th thresholding, wherein S, P are the integer more than or equal to 1, and P is less than etc. It is higher than the 5th thresholding in the TEBS of S and/or user equipment to report, if whether had in P TTI in S TTI on user equipment The UPH of report is above the 6th thresholding and/or the TEBS of user equipment to report is higher than the 5th thresholding, then meaning that user equipment It needs to carry out TTI switching, and is the switching for triggering 10msTTI to 2msTTI.

Wherein, in above-mentioned third embodiment and the 4th embodiment, the 4th thresholding and the 6th thresholding can be identical, It can be different.And in above-mentioned four kinds of modes, the first thresholding and the 4th thresholding may be the same or different, and third thresholding It may be the same or different with the 6th thresholding.

Certainly, in practice, whether base station can also execute TTI switching by other parameters or algorithm come decision, The application is not construed as limiting.

When base station decision will execute TTI switching, then just generation indication message, then executes step 202.

In a further embodiment, this method further includes step 203: base station receives the confirmation letter that user equipment is sent Breath.Wherein, the received confirmation message in base station is corresponding with the confirmation message that user equipment is sent in step 203, and confirmation message exists It when describing the method for user equipment side in previous embodiment one, has been described in detail, so details are not described herein.

Further, if within maximum time, base station does not receive confirmation message, then retransmits indication message, That is, repeating step 202, wherein maximum time be it is predefined or configurable, such as RNC to base station configure one most The big time, then base station is just within the maximum time to base station feedback confirmation message.In the present embodiment, RNC is user equipment The maximum time of configuration and the maximum time configured for base station are identical.

In a further embodiment, after step 202, before step 203 or later, this method further includes step 204: base station sends MAC-i/is Reset instruction or MAC-is Reset instruction to RNC, so that TSN is set to 0 by RNC.

In a further embodiment, after step 202, before step 203 or later, this method further includes step 205: base station sends the target TTI after the switching of user equipment to RNC.To inform the type of the current TTI of RNC user equipment. Such as FP frame or signaling (such as RADIO LINK RESTORE INDICATION or RADIO LINK can be passed through PARAMETER UPDATE INDICATION) it indicates.

In a further embodiment, after step 202, before step 203 or later, this method further include: benefit The upstream data sent with target TTI parsing user equipment.

In order to be compatible with the TTI switching flow of RRC signaling triggering in the prior art, while in order to guarantee only one node Control TTI switching；Allow RNC to turn off the TTI switching modes of base station triggers, then controls the switching of TTI by RNC, such as When the soft handover area of user equipment movement, note that the TTI switching of base station triggers is closed in base station.Therefore, base station, which has, closes The operating mode of TTI switching and the operating mode for opening TTI switching, and in the case where base station is in the operating mode for opening TTI switching, Execute step 202.

Further, base station receives the instruction information that radio network controller is sent, and the work that base station is switched by closing TTI Operation mode is switched to the operating mode for opening TTI switching, or base station is switched to closing by the operating mode for opening TTI switching The operating mode of TTI switching.

In practice, RNC has but is not limited to the sending method of following two instruction information:

The first, by including in reallocation message or relevant configuration information not comprising prewired TTI indicates；

Second, by increasing a display switch instruction in reallocation message, when the TTI switch operating mould of base station to be closed When formula, the relevant configuration information of prewired TTI can not be deleted.

Such as RNC indicates that TTI is closed in base station by RADIO LINK RECONFIGURATION REQUEST/Response Switching, optionally, it is currently used that the user equipment is fed back in RADIO LINK RECONFIGURATION Response in base station Target TTI type.

Further, in order to be applied to soft handover field, while step 202 or later, this method further include: base station to Wireless network control sends instruction information, so that radio network controller sends instruction information to non-serving base stations, so that non-clothes Business base station switches to the target TTI after switching.

It preferably, include the temporal information for switching to target TTI in the instruction information.

Illustrate the TTI switching method in the present invention by a specific example again below, first assumes that base station is in and open The operating mode for opening TTI switching, please refers to shown in Fig. 5, this method comprises:

Step 301:UE and base station report the ability instruction for supporting TTI to switch to RNC；

In another aspect of this invention, it can be by base station controller (RNC) triggering TTI switching, carry out asynchronous reconfiguration, it should The advantages of method, is to switch with quick execution TTI, will be described in detail the process of RNC triggering TTI switching below.

As shown in Figure 10, the method flow diagram of the TTI switching between RNC, base station and UE.This method comprises:

Step 801:RNC sends TTI indication message to UE and base station；

Step 802:UE receives the TTI indication message that RNC is sent；

Embodiment seven, i.e., by taking user equipment side as an example, TTI switching method includes: step 802, step 804, is further gone back It may include step 806；It further, can also include step 808.

Embodiment eight, i.e., by taking base station side as an example, TTI switching method includes: step 803, step 805, further can be with Including step 807.

The implementation process of TTI switching method in the present embodiment described in detail below.

Firstly, step 801, RNC sends TTI indication message to UE and base station, and in practice, RNC is sent out to UE The TTI indication message sent can establish message (RADIO BEARER SETUP) or radio bearer carrying weight for radio bearer With message (RADIO BEARER RECONFIGURATION) or transmission channel reallocation message (TRANSPORT CHANNEL RECONFIGURATION), the TTI switch indicating information that RNC is sent to base station can be wireless link reallocation message (RADIO LINK RECONFIGURATION REQUEST)。

Further, the TTI switch indicating information is used to indicate UE from E-DCH 2ms TTI and is switched to E-DCH 10ms TTI is perhaps used to indicate UE and is switched to E-DCH 2ms TTI from E-DCH 10ms TTI or is used to indicate UE from E-DCH 10ms TTI is switched to R99DCH channel.

It optionally, include the first gain factor and the second gain factor, the first gain factor in the TTI indication message The power of control channel when for determining that user equipment is sent not comprising TTI switching instruction confirmation message, such as determining companion With the power of control channel (DPCCH or E-DPCCH) when sending data channel (DPDCH or E-DPDCH)；Second gain factor is used Switch the power for indicating the control channel (DPCCH or E-DPCCH) of confirmation message comprising TTI in determining that user equipment is sent.It should The advantages of containing at least two gain factor in TTI indication message is, when user equipment receives TTI indication message Afterwards, the control channel for carrying the transformat combination of TTI switching instruction confirmation message is sent with bigger power, just so as to base station The control channel is really decoded, determines that user equipment is switched to the opportunity of target TTI.

Corresponding to the side UE, it is carried out step 802, i.e., the TTI switching instruction that reception radio network controller (RNC) is sent is believed Breath.

Corresponding to base station side, it is carried out step 803, i.e., the TTI switching instruction that reception radio network controller (RNC) is sent is believed Breath.Wherein, step 802 and step 803 are in practice, it may be possible to be performed simultaneously, it is also possible to not be performed simultaneously, take Certainly in the communication conditions of communication network.

Next, UE is carried out step 804, that is, the control channel for carrying transformat combination is sent to base station, so that base Standing can determine that user equipment has been received by indication message based on transformat combination.

In practice, step 804 has numerous embodiments, and concrete example is described as follows:

In the first embodiment, step 804 is specially and carries to prohibit in enhancing Dedicated Physical Control Channel (E-DPCCH) The enhancing dedicated transmission channel format that only uses merges instruction (E-TFCI) to indicate that user equipment has been received by indication message, Wherein, the E-TFCI being forbidden to use is predefined configurable or reserved.Such as can be configured by RNC, than Such as using the E- being forbidden to use in 2ms TTI E-DCH TBS (Transport Block Size, transport block size) table TFCI.The E-TFCI is reserved for another example, it is impossible to be used in normal data transmission is served only for instruction user and is properly received switching Indicate information.Or

User equipment sends and individually carries the physical control channel that non-zero transmission channel format merges instruction (TFCI) (DPCCH) indicating that user equipment has been received by indication message, wherein non-zero TFCI is predefined, or configurable.

Such as when all service bearers of user equipment are in E-DCH, and the currently used TTI type of user equipment is E- DCH 10ms, at this moment because not having R99 business, TFCI is 0 in DPCCH；(E-DCH after UE receives indication message 10ms TTI is switched to the indication message of DCH 10ms TTI), then it sends and carries the DPCCH of non-zero TFCI individually to refer to Show that UE receives indication message；Corresponding base station detects that the TFCI in the DPCCH is nonzero value, then it is assumed that UE is properly received Indication message, non-zero TFCI are predefined or configurable.It should be noted that independent transmission mentioned here refers to DPCCH channel is individually sent, and there is no the channels of adjoint Dedicated Physical Data Channel (DPDCH) to send.

For another example when user equipment receives TTI indication message, and the indication message indicates UE from E-DCH When 2ms switches E-DCH 10ms TTI, user equipment only sends E-DPCCH and does not send E-DPDCH.Optionally, E-DPCCH at this time In include E-TFCI be not used in normal data transfer, which can be predefined or configurable；Optionally, it is Guarantee that the E-DPCCH is detected by base station, the maximum power that user equipment can permit sends E-DPCCH, or with above-mentioned Second gain factor determines the transmission power of the E-DPCCH.This method also can be applied to the switching of E-DCH to R99DCH.

For another example when user equipment receives TTI indication message, and the indication message indicates UE from E-DCH When 10ms is switched to R99DCH, user equipment only sends DPCCH and does not send DPDCH.Before the handover, it is carried in DPCCH channel TFCI is a predefined value, for example is 0；After user equipment receives indication message, individual DPCCH is sent, and should A nonzero value is carried in individual DPCCH；Base station detects the DPCCH channel for carrying the TFCI of nonzero value, then can determine User equipment has received indication message, and then can determine that user equipment is switched to the opportunity of R99DCH.This method It can be applied to the switching of E-DCH 2msTTI Yu E-DCH 10ms TTI.

Optionally, in order to guarantee that the DPCCH is detected by base station, user equipment sends DPCCH with the maximum power allowed, Or the power of the DPCCH is determined with above-mentioned second gain factor.

In this second embodiment, step 804 specifically: when the current TTI of user equipment is 2ms TTI, and user The power headroom UPH value that equipment is sent to base station is less than first threshold, then user equipment, which is sent, carries the first enhancing dedicated transmissions Channel format merges the enhancing Dedicated Physical Control Channel (E-DPCCH) of instruction (E-TFCI), to indicate that user equipment has received To indication message, the first E-TFCI is predefined or configurable；Alternatively,

When user equipment current TTI be 10ms TTI, and user equipment be sent to base station UPH value be greater than the second threshold Value, then user equipment, which is sent, carries the dedicated physics control of enhancing that the second enhancing dedicated transmission channel format merges instruction (E-TFCI) Channel (E-DPCCH) processed, to indicate that user equipment has received indication message, the 2nd E-TFCI is predefined or can match It sets.

Specifically, when UPH be less than first threshold, then illustrate user be in power limited or cover constrained state, at this moment Higher speed rates E-DCH data can not be used, i.e., it is generally acknowledged that at this moment E-TFCI value is smaller；So when UE receives E- After DCH 2ms is switched to the indication message of 10ms TTI, sends and carry the first E-TFCI (the first E-TFCI value is larger) E-DPCCH, so that it may indicate that the base station UE is properly received indication message.It is cut correspondingly, base station has sent E-DCH 2ms After being changed to the indication message of 10ms TTI, the E-DPCCH for carrying the E-TFCI (i.e. the first E-TFCI) of the larger value is detected Channel, then it is assumed that UE receives the TTI indication message that E-DCH 2ms is switched to 10ms.Here the first E-TFCI can be used It is transmitted in E-DCH data, only when UPH is less than first threshold, UE does not select the first E-TFCI to pass for E-DCH data It is defeated, so UE can be indicated to receive the indication message of base station transmission with the first E-TFCI.

When UPH be greater than second threshold, then illustrate that user is in cell near point or midpoint, at this moment can not use smaller Speed rates E-DCH data, i.e., it is generally acknowledged that at this moment E-TFCI value is larger；It is switched to 2ms's when UE receives E-DCH 10ms After TTI indication message, sending the 2nd E-TFCI of carrying, (the 2nd E-TFCI value is smaller, less than the first E-TFCI；Either Minimum value in E-DCH transport block size table E-DCH Transport Block Size Table) E-DPCCH.Accordingly , base station has been sent after E-DCH10ms is switched to the TTI indication message of 2ms, detects the E-TFCI's for carrying smaller value E-DPCCH channel, then it is assumed that UE receives the TTI handover request that E-DCH 10ms is switched to 2ms.

The step of corresponding to base station side as step 805, receive UE send carrying transformat combination control channel, Determine that user equipment has been received by indication message with this, because both sides have had an agreement in certain for receiving indication message A radio frames are switched to target TTI, such as time point that is predefined or being pre-configured just switches, so base station is assured that user Equipment uses the opportunity of target TTI, then it is known that when with target TTI corresponding with indication message decoding use The upstream data that family equipment is sent, so base station is not needed in the prior art after receiving the reconfiguration signaling of RNC, according to Switching both front and back TTI type attempts parsing and leads to the hardware resource for wasting base station, therefore, the method in the embodiment of the present invention The hardware resource of base station can be saved.

Next, UE executes step 806, i.e., it is switched to and indication message pair at time point that is predefined or being pre-configured The target TTI answered, by taking E-DCH 2ms to E-DCH 10ms TTI switching as an example, user equipment has been sent comprising TTI switching instruction After the E-DPCCH or DPCCH of confirmation message, 10ms TTI is switched in next or several radio frames.

Again by taking E-DCH 10ms to E-DCH 2ms TTI switching as an example, user equipment has sent true comprising TTI switching instruction After recognizing the E-DPCCH or DPCCH of information, N number of subframe is switched to E-DCH 2ms TTI under；N is predefined, or configurable 's.

Then UE executes step 808, i.e. user equipment sends handoff completion message with target TTI.

Wherein, which is that radio bearer establishes completion message (RADIO BEARER SETUP COMPLETE) or radio bearer carrying reconfiguration complete message (RADIO BEARER RECONFIGURATION COMPLETE) or Message (TRANSPORT CHANNEL RECONFIGURATION COMPLETE) is completed in transmission channel reconfiguration.

And for base station side, after step 805, it is carried out step 807, i.e., is opened at time point that is predefined or being pre-configured Begin the upstream data sent with target TTI decoding UE, and target TTI is corresponding with indication message.

Specifically, such as when base station detects E-DPCCH, and the E-TFCI carried in the E-DPCCH is not used in just When regular data transmits, then it is assumed that UE has received TTI indication message；Then base station lower M radio frames or under N number of subframe press The upstream data sent according to target TTI decoding UE；Alternatively,

After base station detects the DPCCH for carrying nonzero value, it is believed that UE has received TTI indication message；Then base Stand lower M radio frames or under N number of subframe according to target TTI decoding UE send upstream data.
