Embodiment 2
In this embodiment, for PUCCH resource impact scheme, for convenience, it is defined as follows：
Some sub-frame of uplink in TDD dynamic frame structure scenes fed back for " being passed in descending sub frame incompatible R10
System PDCCH " PUCCH format 1/1a/1b：PUCCH format 1d；Some sub-frame of uplink institute in TDD dynamic frame structure scenes is anti-
Feedback for " EPDCCH " PUCCH format 1/1a/1b in descending sub frame incompatible R10：PUCCH format 1e.
The present embodiment is directed to dynamic tdd frame structure allocation scenarios（It is assumed that R12 or later release support the scene）UCI
Mapping scheme.
In order to more fully understand the present embodiment, below first to TDD service adaptation interference managements（Interference
Management Traffic Adaptation, referred to as IMTA）The problem of middle UCI mappings can run into illustrates：Existing mark
Accurate UCI 1/1a/1b are mapped by the way of Channel assignment, i.e., for each frame structure, a sub-frame of uplink carrying
UCI corresponding to one or more descending sub frame PDSCH.Each configuration PDSCH PDCCH index determines UCI 1/
1a/1b position.In switching at runtime scene, because decipherings of the R11 and R12 to frame structure is different, cause what sub-frame of uplink carried
The mapping relations of descending sub frame are different, therefore are easy to that UCI conflicts occur.
For R12UE, such as UE 1, may be configured as carrying out frame structure deciphering according to SIB-1 configuration（I.e. can
Solution reads actual frame structure）.Assuming that SIB-1 is frame structure 0；UE1 is in frame n-1（That is the previous frame of present frame）Match somebody with somebody in accordance with SIB-1
Put, in frame n（That is present frame）Dynamically it is configured with frame structure 2 and occupies subframe #0；Frame n-1 is frame knot in actual transmissions
Structure 1, frame n are frame structures 2.As shown in fig. 6, the UCI of 3 descending sub frames is then fed back in frame n subframe #7：
Frame n subframe #1：In order to avoid the conflict in problem 1 above, the UCI should be fully according to R10 specifications (EPDCCH
Part is according to R11 specifications) reserve and；
Subframe #9 in frame n-1：It is assumed that the subframe is taken by 2 ~ N of UE；
Frame n subframe #0：The subframe is taken by UE1；
Divide 2 kinds of situation discussion further below：
（1）UE1 knows that frame n-1 practical structures are frame structures 1, and specific scheme can be dynamic by broadcast signaling
The actual frame structure of present frame is configured, while notifies that R12 UE is the frame structure in accordance with SIB-1 using the specific control signalings of UE
Or the frame structure of dynamic broadcast signaling instruction.So although UE1 is caused to observe SIB-1 frame structures, UE2 in frame n-1
Actual frame structure can be perceived, can avoid being directed to subframe #9 UCI in frame n-1 when frame n subframe #7 feeds back UCI
Position.
However, there is problems with this allocation plan：Dynamic broadcast signaling adds UE blind Detecting numbers；While in order to
