By appointment selection rule of this base station (with the UE side regular identical) detects the ACK/NACK information of descending sub frame on target P UCCH, if do not detect corresponding ACK/NACK information, the downlink data mistake is described, be considered as the NACK confirmation, need to retransmit, if detect corresponding ACK/NACK information, then judge whether that according to detected ACK/NACK result of information needs retransmit.Therefore, this base station has overcome the expression confirmation may exist the problem of DTX, and then has reached the effect that guarantees the complete effective transmission of downlink data.
Below by introducing this rule for example in detail.
The ACK/NACK confirmation of UE side feeding back downlink subframe correspondence (through with operation after affirmation information) treaty rule (base station side detect also follow this rule) of PUCCH index at place is as follows:
Configuration and other constraintss according to LTE TDD, determine that the descending sub frame manifold of the affirmation information correspondence fed back closes K in a sub-frame of uplink, as K={1,2,3,4} is illustrated in can have the affirmation information of 1 or 2 or 3 or 4 descending sub frame correspondence to transmit in this sub-frame of uplink in the sub-frame of uplink; Element among the set K is pressed from big to small or rank order from small to large;
Odd number element among the set K of regulation after through ordering correspond to feeding back ACK/NACK acknowledge message on the PUCCH of the implicit indication of CCE sequence number of minimum at the corresponding PDCCH of first descending sub frame place that this UE receives according to UE in descending sub frame corresponding to this sub-frame of uplink (through and the affirmation message of operation), the even number element among the set K of regulation after through ordering correspond to feeding back ACK/NACK acknowledge message on the PUCCH of the implicit indication of CCE sequence number of minimum at the corresponding PDCCH of last descending sub frame place that this UE receives according to UE in descending sub frame corresponding to this sub-frame of uplink (through and the affirmation message of operation).
Perhaps opposite, promptly the odd number element among the set K of regulation after through ordering correspond to feeding back ACK/NACK acknowledge message on the PUCCH of the implicit indication of CCE sequence number of minimum at the corresponding PDCCH of last descending sub frame place that this UE receives according to UE in the descending sub frame of this sub-frame of uplink correspondence (through and the affirmation message of operation), even number element among the set K of regulation after through ordering correspond to feeding back ACK/NACK acknowledge message on the PUCCH of the implicit indication of CCE sequence number of minimum at the corresponding PDCCH of first descending sub frame place that this UE receives according to UE in the descending sub frame of this sub-frame of uplink correspondence (through and the affirmation message of operation), as shown in Figure 3:
For example, work as K={1,2,3, (sequenced preface) during 4}:
When UE receives four descending sub frame data, and when determining feed back the affirmation message of these four descending sub frame data in a sub-frame of uplink, the PUCCH of the implicit indication of CCE sequence number of the minimum at last (or first) the corresponding PDCCH of descending sub frame data place that UE receives according to UE in the descending sub frame of this sub-frame of uplink correspondence is feeding back ACK/nack message upward;
When UE receives three descending sub frame data, and when determining feed back the affirmation message of these three descending sub frame data in a sub-frame of uplink, the PUCCH of the implicit indication of CCE sequence number of the minimum at first (or last) the corresponding PDCCH of descending sub frame data place that UE receives according to UE in the descending sub frame of this sub-frame of uplink correspondence is feeding back ACK/nack message upward;
When UE receives two descending sub frame data, and when determining feed back the affirmation message of these two descending sub frame data in a sub-frame of uplink, the PUCCH of the implicit indication of CCE sequence number of the minimum at last (or first) the corresponding PDCCH of descending sub frame data place that UE receives according to UE in the descending sub frame of this sub-frame of uplink correspondence is feeding back ACK/nack message upward;
When UE receives descending sub frame data, and when determining to feed back the affirmation message of these descending sub frame data in a sub-frame of uplink, UE is feeding back ACK/nack message on the PUCCH of the implicit indication of CCE sequence number of the minimum at the corresponding PDCCH of these descending sub frame data place that receives.
Known when the affirmation information of certain UE is detected in the base station in sub-frame of uplink have the affirmation message of what descending sub frame data to feed back in this sub-frame of uplink, and the also sequence number of known these descending sub frames.
Supposing that the base station is known has the affirmation message of four descending sub frame data to launch in this sub-frame of uplink, then the PUCCH of the implicit indication of CCE sequence number of the minimum at last that distribute to this UE in the descending sub frame of this sub-frame of uplink correspondence (or first) the corresponding PDCCH of descending sub frame data place need be detected in the base station, if do not detect ACK/NACK, then think DTX, being used as NACK handles, if detect ACK/NACK, then need to judge whether to retransmit according to detected ACK/NACK;
Supposing that the base station is known has the affirmation message of three descending sub frame data to launch in this sub-frame of uplink, then the PUCCH of the implicit indication of CCE sequence number of the minimum at first that distribute to this UE in the descending sub frame of this sub-frame of uplink correspondence (or last) the corresponding PDCCH of descending sub frame data place need be detected in the base station, if do not detect ACK/NACK, then think DTX, being used as NACK handles, if detect ACK/NACK, then need to judge whether to retransmit according to detected ACK/NACK;
Supposing that the base station is known has the affirmation message of two descending sub frame data to launch in this sub-frame of uplink, then the PUCCH of the implicit indication of CCE sequence number of the minimum at last that distribute to this UE in the descending sub frame of this sub-frame of uplink correspondence (or first) the corresponding PDCCH of descending sub frame data place need be detected in the base station, if do not detect ACK/NACK, then think DTX, being used as NACK handles, if detect ACK/NACK, then need to judge whether to retransmit according to detected ACK/NACK;
Supposing that the base station is known has the affirmation message of descending sub frame data to launch in this sub-frame of uplink, then the implicit PUCCH that indicates of CCE sequence number of the minimum at the corresponding PDCCH of these descending sub frame data place of distributing to this UE in the descending sub frame of this sub-frame of uplink correspondence need be detected in the base station, if do not detect ACK/NACK, then think DTX, being used as NACK handles, if detect ACK/NACK, then need to judge whether to retransmit according to detected ACK/NACK;
The element that the descending sub frame manifold of the affirmation information correspondence of feeding back in the sub-frame of uplink is closed among the K can be selected according to the up-downgoing proportional arrangement, as:
5ms cycle transfer point
10ms cycle transfer point
Configuration 5, K is any nonvoid subset of set M, M={1 wherein, 2,3,4,5,6,7,8,9};
Send confirmation ACK (Acknowledge in the capable physically control channel that can detect DTX of this embodiment design, correctly reply) and NACK (Non-Acknowledge, wrong responses) method and detection method thereof can solve the problem of downlink data mistake, thereby minimizing time delay, the performance of assurance system can effectively improve feedback efficiency and system works efficient.
With LTE TDD system is example, suppose, continuous 20 subframes, when the up-downgoing proportional arrangement is the configuration 4 of above-mentioned table 1, subframe 0, subframe 1, subframe 4, subframe 5, subframe 6, subframe 7, subframe 8, subframe 9, subframe 10, subframe 11, subframe 14, subframe 15, subframe 16, subframe 17, subframe 18, subframe 19 are descending sub frame, subframe 2, subframe 3, subframe 12, subframe 13 are sub-frame of uplink, according to the up-downgoing timing relationship, the ACK/NACK of subframe 0,1,4,5 is in subframe 12 feedbacks, the ACK/NACK of subframe 6,7,8,9 is in subframe 13 feedbacks, as shown in Figure 6;
Obvious K={1 at this moment, 2,3,4};
Suppose that the base station sends data to object UE on descending sub frame 6,7,8,9:
When UE received the descending sub frame data, if do not detect the PDCCH of subframe 4, the data on the subframe 4 made a mistake, and the data of other subframes normally receive; Because UE receives the data of three subframes, therefore, UE goes up feeding back ACK/nack message at the PUCCH of the implicit indication of CCE sequence number of the minimum at the corresponding PDCCH of first descending sub frame that receives (subframe 6) data place;
In base station side, having 4 descending sub frames owing to the base station is known has data to send to object UE, so detection ACK/NACK information is gone up at the PUCCH of the implicit indication of CCE sequence number of the minimum at the corresponding PDCCH of last descending sub frame (subframe 9) place that sends in the base station; Because UE do not send ACK/NACK on this channel, so the base station detects DTX, and the base station can be handled according to the NACK mode.
May there be the problem of DTX because adopted the position of sub-frame of uplink to help to express confirmation in above embodiment so overcome the expression confirmation, and then has reached the effect that guarantees the complete effective transmission of downlink data.
