Embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
The invention provides a kind of uplink data transmission method, Fig. 1 is the flow chart according to the uplink data transmission method of the embodiment of the present invention, as shown in Figure 1, comprises that following step S102 is to step S106.
Step S102, UE determine that upstream data to be sent is last bag data in the UE buffer memory.
Step S104 increases sign in upstream data to be sent, wherein to be used to indicate upstream data to be sent be last bag data in the UE buffer memory to sign.
Step S106 sends upstream data to be sent to eNB.
In correlation technique, after UE carried out last bag transfer of data in buffer memory, eNB was to the mandate of an ACK of UE feedback and a new data packets, but will not send out because UE has had data, therefore can cause the wasting of resources.In the embodiment of the present invention, by increase sign in upstream data to be sent, UE can inform that the upstream data of eNB transmission is last bag data in the UE buffer memory, thereby can avoid eNB to the mandate of UE feedback new data packets, avoids the wasting of resources.
Wherein, step S104 comprises: increase sign in the reservation bit in the MAC PDU in upstream data to be sent or filling bit.In this preferred embodiment, by increasing sign in the reservation bit in the MAC PDU in upstream data to be sent or filling bit, its implementation is convenient, reliable.
The below is introduced the dual mode of above-mentioned increase sign respectively.
(1) increase sign in the reservation bit in the MAC PDU in upstream data to be sent, specific as follows: first reservation bit in the MAC PDU in upstream data to be sent is set to one.
(2) increase sign in the filling bit in the MAC PDU in upstream data to be sent, specific as follows: first reservation bit in the filling bit in the MAC PDU in upstream data to be sent is set to one.
And then after step S106, the operation of eNB is as follows: eNB receives upstream data to be sent; ENB determines that according to sign the data that receive are last bag data in the UE buffer memory; ENB is to UE feeding back ACK only.In this preferred embodiment, eNB only gives the UE feeding back ACK, and the mandate of not feeding back new data packets.Owing to having avoided empty uplink authorization, therefore reduced the scheduler handle of eNB, promoted simultaneously spectrum utilization efficiency.
Consider in correlation technique in the situation that eNB only to the UE feeding back ACK, UE will get up data buffering, detect the re-transmission mandate of these bag data on corresponding descending sub frame always, long-time with no authorized, UE may initiate dispatch request, therefore can cause so on the one hand the power consumption of UE to increase, authorize for detection of retransmitting, may cause the frequency spectrum resource utilization to descend because UE initiates dispatch request on the other hand, can increase simultaneously the propagation delay time of these bag data.So in the present invention, to UE only after feeding back ACK, the operation of UE is as follows: UE receives ACK at eNB; UE deletes upstream data to be sent in buffering.In this preferred embodiment, in the situation that eNB only gives the UE feeding back ACK, think that namely these bag data correctly transmit, can delete in buffering, thereby reduced the blind Detecting number of times of UE, and then reduced the power consumption of UE, and avoided UE because last bag data are initiated dispatch request, therefore promoted the availability of frequency spectrum.
Fig. 2 is the flow chart of uplink data transmission method according to the preferred embodiment of the invention, as shown in Figure 2, comprises that following step S202 is to step S208.
Step S202, in the LTE system, during last bag data in sending its buffer memory of terminal, identify in (reserved) bit of the reservation in MAC PDU or filling bit (Padding bit), wrap data in order to last that illustrates that these bag data are business.
Step S204, eNB finds reservation bit or the peculiar non-zero setting of packing ratio after correct receive data bag, think that these bag data are last bag data in buffer memory.
Step S206, eNB be feeding back ACK only, represents that these bag data correctly transmit.
Step S208, UE for the data packet transmission of having carried out mark after, if the ACK of these bag data detected, think that these bag data correctly transmit, can delete in buffering, this business is end of transmission also.
Be described in detail below in conjunction with the implementation procedure of example to the embodiment of the present invention.
A UE in the end bag during transfer of data, is set in the partial bit of reservation bit or filling bit " 1 "; ENB checks reservation bit or the filling bit of MAC PDU after successful receive data, take determine these bag data whether last in the buffer memory wrap data; If being checked through is last bag data, feeding back ACK only in buffer memory; After UE last bag data in sending buffer memory, and only receive ACK, represent that these bag data correctly receive, and this business has been completed transmission.
