Embodiment
In the embodiment of the present invention after receiving the resource distribution message needing to activate immediately, be configured operation, but do not activate immediately, but determine an activationary time, make before arrival activationary time, have time enough to generate and a transmission ACK, to prevent or to reduce network side re-transmission resource configuration messages, save Internet resources, and the operation can effectively avoiding network side to carry out for link exception.
See Fig. 1, the main method flow process activating configuration in the present embodiment is as follows:
Step 101: receive the resource distribution message that network side sends, resource distribution message carries the indication information activated immediately.
Step 102: after receiving the indication information activated immediately, determines according to the required duration of the acknowledge message (ACK) generating and send resource distribution message the time activating configuration.
Step 103: generate and send ACK before arriving the time activating configuration.
Step 104: activate configuration when arriving the time activating configuration.
Wherein, the time that activation configures is that frame number when receiving resource distribution message adds delay frame number, i.e. CfgActTime (activating the time of configuration)=CurrCFN (current frame number)+DelayFN (delay frame number).
DelayFN and generation and to send duration needed for ACK relevant, comprise medium education (MAC) layer and the frame number needed for physical layer process ACK and UE and send frame number needed for this ACK, i.e. DelayFN=Trach (or MaxUlOldTti)+DataAhead, Trach (or MaxUlOldTti) represents that UE sends the frame number needed for an ACK, DataAhead represents frame number needed for MAC layer and physical layer process ACK (the transmission frame number of Cell-FACH state is the transmission frame number of Trach, Cell-DCH state is MaxUlOldTti).
Transmitting data between MAC layer and physical layer is with TTI (Transmission Time Interval) for unit, in the section start transmission data of each TTI.Different according to configuration, TTI can have multiple value, as 1,2,4,8 frames (corresponding 10ms, 20ms, 40ms, 80ms).Based on MAC layer and the treatment mechanism of physical layer and the disposal ability of hardware device, the value of DataAhead is more fixing, does not need to change in the long period.Preferably, the span of DataAhead is 1 ~ 3 frame (realization of each UE is different, and this value is more short better, but this value to be less than 1 frame unrealistic), and concrete value is determined by actual conditions.
The frame number that UE sends needed for ACK is relevant with rrc layer status, and it is different that different states sends process needed for ACK.RRC state comprises Cell-FACH (cell forward access channel) state and Cell-DCH (cell private channel) state.When RRC state is Cell-FACH state, the duration that UE sends ACK comprises: uplink synchronous code is selected and transmission, FPACH (forward physical access channel) receive synchronizing information, wait in the upper transmission of PRACH (Physical Random Access Channel) and send the required maximum frame number sum (being designated as Trach) of ACK difference on prach.Such as, uplink synchronous code is selected and is sent 1 subframe consuming time, and FPACH receives 4 subframes consuming time, waits PRACH to be sent 2 subframes consuming time, sends PRACH 1 ~ 4 subframe consuming time, 8 ~ 11 subframes consuming time altogether.Wherein send a PRACH TTI consuming time, if corresponding 1 subframe, then send PRACH 1 subframe consuming time, because the value that TTI is possible is 1,2,4 subframes, so send PRACH 1 ~ 4 subframe consuming time.Rrc layer needs when being configured operation packed by configuration information and be sent to MAC layer, will generate ACK simultaneously.There is a kind of situation is that rrc layer cannot generate ACK at the same frame of packing configuration information, therefore need to do a correction, the first modified values (in the present embodiment, value is 1) is increased, then DelayFN=Trach+DataAhead+1 (the first modified values) in DelayFN.In addition, the TTI before and after configuration may be different, in order to synchronous with network side preferably, can be alignd by the TTI of new and old configuration by the second correction value, then DelayFN=Trach+DataAhead+1+TH (the second modified values), TH >=0.
When RRC state is Cell-DCH state, the duration that UE sends ACK comprises: the frame number MaxUlOldTti that before activating configuration, in old configuration, up maximum TTI is corresponding, this MaxUlOldTti can obtain from bottom (MAC layer or physical layer) configuration.Further, similar with Cell-FACH state, rrc layer needs when being configured operation packed by configuration information and be sent to MAC layer, will generate ACK simultaneously.There is a kind of situation is that rrc layer cannot generate ACK at the same frame of packing configuration information, therefore need to do a correction, the first modified values (in the present embodiment, value is 1) is increased, then DelayFN=MaxUlOldTti+DataAhead+1 (the first modified values) in DelayFN.In addition, the TTI before and after configuration may be different, in order to synchronous with network side preferably, can be alignd by the TTI of new and old configuration by the second correction value, then DelayFN=MaxUlOldTti+DataAhead+1+TH (the second modified values), TH >=0.Such as, have two Trch, TTI to be respectively 20ms (2 frame) and 40ms (4 frame), then activationary time must be just the multiple place onset of 4 frames at CFN (continuous frame number); Again because activationary time means the inefficacy of old configuration, then this time point must ensure that the boundary (section start or end) of the maximum TTI in old configuration lost efficacy, to ensure that the data in old configuration can Successful transmissions.If current activationary time is 3 (frame numbers), and MaxOldTti (old TTI)=4, MaxNewTti (new TTI)=8, then the activationary time point after TTI alignment is 8, then TH=5; If current activationary time is 8, MaxOldTti=4, MaxNewTti=8, be then still 8 after alignment, therefore after TTI alignment, activationary time may be constant, then TH=0.
By the foregoing describing the mode of having separated and having determined activationary time, especially postpone frame number.Visible, postpone the second correction value part in frame number to need new and old TTI to determine, new TTI could be obtained after only receiving resource distribution message, therefore the second correction value needs to determine temporarily, other parts are all relatively fixing, if do not consider the second correction value, then determine to postpone frame number after receiving resource distribution message at every turn.Two states below for RRC introduces the implementation procedure activating configuration in detail.
See Fig. 2, the method flow activating configuration when RRC state is Cell-FACH state in the present embodiment is as follows:
Step 201: subscriber equipment receives the resource distribution message that network side sends under Cell-FACH state.This resource distribution message carries the indication information activated immediately.
Step 202: subscriber equipment determines activationary time according to the correction generating ACK required time, random access procedure and TTI alignment.CfgActTime＝CurrCFN+Trach+DataAhead+1+TH。
Step 203: subscriber equipment is configured operation.Configuration operation as: by configuration information assignment in the configuration space of MAC layer and physical layer.
Step 204: subscriber equipment generates ACK.
Step 205: subscriber equipment sends ACK in arrival activationary time feedforward network side.Step 204 and 205 synchronously can be carried out with step 203.
Step 206: subscriber equipment activates configuration when arriving activationary time.
After activation configuration, MAC layer will stop the data in old configuration to send, and physical layer starts the synchronizing process of carrying out new configuration simultaneously.The new configuration synchronization success of notice RRC after physical layer synchronization success, now think and newly configure onset, subscriber equipment sends configuration with AM pattern to network side and completes message, and waits for that network side replys ACK, and after receiving the ACK of network side feedback, layoutprocedure terminates.
See Fig. 3, the method flow activating configuration when RRC state is Cell-DCH state in the present embodiment is as follows:
Step 301: subscriber equipment receives the resource distribution message that network side sends under Cell-DCH state.This resource distribution message carries the indication information and new TTI that activate immediately.
Step 302: subscriber equipment determines activationary time according to the correction generating ACK required time, maximum TTI and TTI of old collocating uplink aligns.CfgActTime＝CurrCFN+MaxUlOldTti+DataAhead+1+TH。
Step 303: subscriber equipment is configured operation.Configuration operation as: by configuration information assignment in the configuration space of MAC layer and physical layer.
Step 304: subscriber equipment generates ACK.
Step 305: subscriber equipment sends ACK in arrival activationary time feedforward network side.Step 304 and 305 synchronously can be carried out with step 303.
Step 306: subscriber equipment activates configuration when arriving activationary time.
Subscriber equipment can also send configuration with AM pattern to network side and complete message after activation configuration, and receives the ACK of network side feedback.
