Abstract
The invention provides a method for sending repeated acknowledgement (ACK)/negative acknowledgment (NACK) feedback, a system and user equipment (UE). 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 sent on the uplink subframe behind the transfer prohibited subframe; or the ACK/NACK feedback is sent on the subframe predetermined to be sent. The method, the system and the UE can solve the problem of reliability of feedback transmission when the subframe for sending the repeated ACK/NACK feedback conflicts with the transfer prohibited subframe, and simultaneously ensure uplink feedback coverage of the UE.
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 UE uplink feedback.Following paper ACK/NACK repeats 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.During receive data, at first UE understands PDCCH, if the descending control command for this UE is arranged, the downlink data that in UE control command descending according to this, demodulates information such as the frequency resource position of appointment and modulation code configuration (MCS, Modulation and Coding Scheme) base station sends.
The LTE system also is based on the system of mixed automatic repeat request (HARQ, Hybrid Automatic Repeat Request).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 because residing position is different, and the channel quality difference is very large, in order to guarantee the reliability of HARQ feedback, has introduced ACK/NACK repetition (ACK/NACK repetition) 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 under default situations, UE only needs the uplink feedback of transmission to downlink data on a sub-frame of uplink; In the situation that open, for downlink data, UE is except sending on a subframe corresponding with the downlink transfer time uplink feedback, also need to after subframe on repeat to send ACK/NACK feedback, at this, will be called for all feedbacks of a downlink data transmission repeat ACK/NACK feedback.
The number of repetition of ACK/NACK repetition is configured by high level, can be 2,4,6.
UE sends the ACK/NACK feedback on a plurality of continuous sub-frame of uplink, 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, the below briefly introduces and forbids transmitting subframe:
The LTE system needs for some may be in data or the feedback of forbidding on the part subframe on UE transmission working frequency range, 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 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 iso-frequency adjacent community or different system adjacent cell into.This time period is called Measurement Gap, 6ms is arranged as Measurement Gap in an every 40ms of general configuration or 80ms.Mobile terminal can not be received and dispatched any information of working frequency range in Measurement Gap.
（2）Blank?subframe
Blank Subframe has via node for the UE that guarantees R8 can be operated in, and the LTE system of (Relay Node) introduces.Because via node just can not send data to UE when receiving the data of base station, just can not receive the data of UE when sending data to the base station, 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 configure 1 in Fig. 1, have respectively 2 sub-frame of uplink and 2 descending sub frames to need and base station communication in a frame due to via node, so UE at this moment can not transceiving 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 existing FDD system.In Fig. 2, subframe 5 is Blank Subframe of UE.
Can be found out by above-mentioned introduction to two kinds of technology, repeat ACK/NACK feedback mechanism requires UE to send repeat ACK/NACK feedback on some subframe, and UE can't send data or feedback forbidding transmitting on subframe, thereby both has conflict.Do not stipulate how to process for above-mentioned conflict in existing LTE system, thereby can cause confusion in actual treatment.
Summary of the invention
