, in order to understand better above-described embodiment 1 and preferred implementation thereof, below in conjunction with embodiment 2 and relevant drawings, illustrate.
In this embodiment, the resource mapping scheme for PUCCH for convenience, is defined as follows:
The PUCCH form 1/1a/1b:PUCCH form 1d for " traditional PD CCH in the incompatible descending sub frame of R10 " that certain sub-frame of uplink in TDD dynamic frame structure scene feeds back; The PUCCH form 1/1a/1b:PUCCH form 1e for " EPDCCH in the incompatible descending sub frame of R10 " that certain sub-frame of uplink in TDD dynamic frame structure scene feeds back.
The present embodiment is for the UCI mapping scheme of dynamic tdd frame structure allocation scenarios (supposition R12 or later release have been supported this scene).
In order to understand better the present embodiment, below first to TDD service adaptation interference management (Interference Management Traffic Adaptation, referred to as IMTA) in the UCI mapping problem that can run into describe: the mode that the UCI 1/1a/1b of existing standard adopts channel to select is shone upon, namely for each frame structure, a sub-frame of uplink is carrying UCI corresponding to one or more descending sub frame PDSCH.The index of the PDCCH of each configuration PDSCH has determined the position of UCI 1/1a/1b.Dynamically in handoff scenario,, because R11 is different to the deciphering of frame structure with R12, cause the mapping relations difference of the descending sub frame of sub-frame of uplink carrying, therefore be easy to occur the UCI conflict.
For R12UE, for example UE 1, may be configured to carry out frame structure according to the configuration of SIB-1 and understand (namely can solution read actual frame structure).Suppose that SIB-1 is frame structure 0; UE1 is the previous frame of present frame at frame n-1() observe the SIB-1 configuration, at frame n(, be present frame) configured dynamically frame structure 2 and taken subframe # 0; In actual transmissions, frame n-1 is frame structure 1, and frame n is frame structure 2.As shown in Figure 6, at the subframe # 7 of frame n, to feed back the UCI of 3 descending sub frames:
The subframe # 1 of frame n: for fear of the conflict in top problem 1, this UCI should reserve out according to R10 standard (the EPDCCH part is according to the R11 standard) fully;
The subframe # 0 of frame n: this subframe is taken by UE1;
Below further minute 2 kinds of situation discussion:
(1) UE1 knows that the practical structures of frame n-1 is frame structure 1, concrete scheme can be to configure dynamically the frame structure of present frame reality by broadcast signaling, and the UE that uses simultaneously the specific control signal notice of UE R12 observes the frame structure of SIB-1 or the frame structure of dynamic broadcast signaling indication.Although make like this UE1 observe the SIB-1 frame structure at frame n-1, UE2 can perceive actual frame structure, can avoid for frame n-1 when the subframe # 7 of frame n feedback UCI in the position of UCI of subframe # 9.
Yet there is following problem in this allocation plan: the dynamic broadcast signaling has increased UE blind Detecting number of times; Need to increase larger signaling consumption for the robustness that guarantees broadcast signaling simultaneously.
(2) UE2 does not know the practical structures of frame n-1, thinks that it is frame structure 0.Another possibility is that UE1 does not perceive actual frame structure at the n-1 frame, and it does not recognize the descending sub frame # 9 in frame n-1, so may clash.
Based on such scheme, the present embodiment proposes a kind of UCI mapping scheme of robust, and namely UE1 does not perceive in the situation of actual frame structure of frame n-1 and can avoid the conflict of UCI yet, and concrete scheme is as follows:

With the incompatible descending sub frame of R10/R11PDSCH, the UCI channel selection principle of sub-frame of uplink # 7 is: first shine upon the UCI for CCE in the present frame descending sub frame, shine upon again the UCI for CCE in the previous frame descending sub frame: following as an example of Fig. 6 example explanation how to carry out the mapping of UCI 1d/1e, in subframe # 7 in the n frame, at first according to the PCFICH value of subframe # 1 in the n frame and EPDCCH capacity, reserve respectively UCI 1/1a/1b(UCI space 1 for subframe #1) and UCI 1c(UCI space 2) thereby conflict with R10/R11UE avoided.Then in the UCI 1d(UCI space 3 of the back in UCI space 1 (more close band center direction) mapping for the subframe # 0 in the n frame and subframe #3), then in the UCI 1e(UCI space 4 of the back in UCI space 2 (more close band center direction) mapping for the subframe # 0 in the n frame and subframe #3).
Perhaps, with the incompatible descending sub frame of R10/R11PDSCH, the UCI channel selection principle of sub-frame of uplink # 7 is: no matter what frame structure R12UE has distributed at previous frame, it all will reserve the UCI resource for previous frame subframe 9:
How explanation carries out the mapping of UCI 1d/1e as an example of Fig. 6 example, in subframe # 7 in the n frame, at first according to the PCFICH value of subframe # 1 in the n frame and EPDCCH capacity, reserve respectively UCI 1/1a/1b(UCI space 1 for subframe #1) and UCI 1c(UCI space 2) thereby conflict with R10/R11UE avoided.Then in the back in UCI space 1 (more close band center direction) according to predefined method (for example block interleaving etc.) the mapping UCI for the subframe # 9 in the subframe # 0 in the n frame and subframe # 3 and frame n-1.The benefit of the method is to reuse existing UCI mapping scheme as far as possible, yet has brought certain UCI overhead losses.
