The method comprises the following steps: the UE respectively judges whether the subframe predetermined to be sent for every ACK/NACK feedback in the repeated ACK/NACK feedback is the transfer prohibited subframe, if so, the ACK/NACK feedback is notsent; or the ACK/NACK feedback is sent on the subframe predetermined to be sent. The method, the system and the UE can take full advantage of the uplink feedback resources.
Description
Technical field
The present invention relates to long evolving system (LTE) technical field, particularly a kind of transmission duplicate acknowledgment (ACK) or deny (NACK) feedback method, system and subscriber equipment (UE).
Background technology
Present LTE RAN1 has determined to introduce ACK/NACK and has repeated the covering problem that feedback system solves the up feedback of UE.Below at first introduce ACK/NACK and repeat feedback system:
The LTE system is based on the system of scheduling, and by base station assigns running time-frequency resource carrying data, UE is according to control command downlink data receiving or the transmission upstream data of base station.For downlink data transmission, the base station is UE configures physical downlink control channel (PDCCH, physical downlink control channel) and downlink data.When receiving data, UE at first understands PDCCH, if the descending control command at this UE is arranged, then UE is according to the downlink data of this descending control command frequency appointed resource location and the transmission of modulation code configuration demodulates information base stations such as (MCS, Modulation and Coding Scheme).
The LTE system also is based on the system of mixed automatic repeat request (HARQ, Hybrid Automatic RepeatRequest).UE sends feedback information according to the demodulation correctness to the base station after the downlink data transmission that receives the base station transmission, namely confirm (ACK) or deny (NACK) feedback, and the base station determines whether that according to the feedback information of receiving needs retransmit downlink transfer.
In same residential quarter, UE is owing to residing position difference, and the channel quality difference is very big, in order to guarantee the reliability of HARQ feedback, has introduced ACK/NACK repetition (ACK/NACKrepetition) mechanism in the LTE system, and its characteristics are as follows:
ACK/NACK repetition is not opened under default situations by high level configuration and release.Be that UE only needs in the up feedback of a sub-frame of uplink transmission to downlink data under the default situations; Under the situation of opening, at downlink data, UE is except sending in a subframe corresponding with the downlink transfer time the up feedback, also need after subframe repeat to send ACK/NACK feedback, at this, will be called repeat ACK/NACK feedback at all feedbacks of a downlink data transmission.
The number of repetition of ACK/NACK repetition is disposed by high level, can be 2,4,6.
UE sends the ACK/NACK feedback at a plurality of continuous sub-frame of uplink, and for TDD, the centre may stride across descending sub frame and special subframe, and absolute time is grown up in the number of repetition of ACK/NACK repetition;
During sending feedback, UE does not send other up signalings.
More than introduced repeat ACK/NACK feedback mechanism, briefly introduced again below and forbid transmitting subframe:
The LTE system needs and may forbid that UE transmits data or the feedback on the working frequency range in the part subframe for some, this part subframe is called as forbids transmitting subframe, and two kinds of typical examples are measurement clearance (Measurement Gap) and blank subframe (blank Subframe).
(1)Measurement?Gap
In order to realize that the residential quarter between alien frequencies or the different system switches, system needs the quit work data transmit-receive of frequency range of configure user equipment in the certain hour section, change the information such as channel quality of measuring the adjacent residential quarter of iso-frequency adjacent community or different system into.This time period is called Measurement Gap, 6ms is arranged as Measurement Gap among the every 40ms of a general configuration or the 80ms.Portable terminal can not be received and dispatched any information of working frequency range in Measurement Gap.
(2)Blank?subframe
Blank Subframe introduces for the UE that guarantees R8 can be operated in the LTE system with via node (RelayNode).Because via node just can not send data to UE when receiving the data of base station, when sending data to the base station, just can not receive the data of UE, so concerning UE be equivalent to blank in this in two moment.
Referring to Fig. 1, Fig. 1 is a kind of Blank Subframe schematic diagram in the existing TDD system, select ascending-descending subframes to be configured to dispose 1 among Fig. 1, because via node has 2 sub-frame of uplink and 2 descending sub frames to need and base station communication in a frame respectively, therefore UE at this moment can not receive and dispatch data on corresponding uplink/downlink frames.As seen, in Fig. 1, subframe 3,4,8 and 9 is Blank subframe of UE.
Referring to Fig. 2, Fig. 2 is a kind of Blank Subframe schematic diagram in the existing FDD system.In Fig. 2, subframe 5 is Blank Subframe of UE.
By above-mentioned introduction to two kinds of technology as can be seen, repeat ACK/NACK feedback mechanism requires UE to send repeat ACK/NACK feedback in some subframe, and UE can't send data or feedback forbidding transmitting on the subframe, thereby there is conflict in the two.According to the conclusion of existing LTE, up feedback with forbid need cancelling up feedback when transmitting subframe conflicts, under repeat ACK/NACK mechanism, this means all repeat ACK of cancellation/NACK feedback.As seen, if the repeat ACK of some/NACK feedback does not have and forbids that transmitting subframe clashes, then cancel the uncertainty that all feedbacks can increase base station scheduling, wasted up feedback resources simultaneously.
Summary of the invention
Method, system and UE that the embodiment of the invention proposes a kind of transmission repeat ACK/NACK feedback can avoid the uncertainty of base station scheduling, and take full advantage of up feedback resources.
Technical scheme of the present invention is achieved in that
The method of a kind of transmission repeat ACK/NACK feedback comprises: UE judges that respectively whether the predetermined transmission subframe of the feedback of ACK/NACK each time in repeat ACK/NACK feedback is for forbidding transmitting subframe, if then do not send described ACK/NACK feedback; Otherwise, send this ACK/NACK feedback in described predetermined transmission subframe.
A kind of system comprises:
UE is used for judging respectively that whether the predetermined transmission subframe of the feedback of ACK/NACK each time of repeat ACK/NACK feedback is for forbidding transmitting subframe, if then do not send described ACK/NACK feedback; Otherwise, send the ACK/NACK feedback in described predetermined transmission subframe;
The base station is used for receiving described ACK/NACK feedback, determines whether to carry out retransfer scheduling according to the ACK/NACK feedback that receives.
A kind of UE is used for judging respectively that whether the predetermined transmission subframe of the feedback of ACK/NACK each time of repeat ACK/NACK feedback is for forbidding transmitting subframe, if then do not send described ACK/NACK feedback; Otherwise, send the ACK/NACK feedback in described predetermined transmission subframe.
As seen, method, system and the UE of the transmission repeat ACK that the present invention proposes/NACK feedback, the predetermined transmission subframe of judging the feedback of ACK/NACK each time in the repeat ACK/NACK feedback respectively whether with forbid that transmitting subframe occurs conflicting, when the predetermined transmission subframe of ACK/NACK feedback when forbidding that transmitting subframe occurs conflicting, then do not send this ACK/NACK and feed back; If conflict do not occur, then send the ACK/NACK feedback in this predetermined subframe that sends.In this way, can avoid the uncertainty of base station scheduling, and take full advantage of up feedback resources.
