A new Rel-12 LTE WID for "Further Enhancements to LTE TDD for uplink / downlink (UL / DL) Interference Management and Traffic Adaptation" has recently been agreed. The main purpose is to enable TDD UL / DL reconstruction for traffic adaptation to TD-LTE systems, including clustered small cell deployments. Unlike legacy (e. G. Rel-8) eNB with semi-static UL / DL configuration, the duplex direction of the flexible subframe in the cell supporting the Rel-12 eIMTA feature is dynamic can be changed. During the elMTA SI phase, characteristics supporting SIB, paging, radio resource control (RRC), medium access layer (MAC) and physical layer signaling, different traffic adaptive time scales A number of signaling options have been extensively discussed.

Regardless of SIB / paging / RRC / MAC / LI signaling, one physical uplink control channel (PUCCH) resource conflict issue arising from UL / DL reconfiguration feature was observed. An example of this issue is shown at 200 in FIG. Although the TDD UL / DL configuration 1 is assumed to be represented in system information block type 1 (SIB1), the actual TDD UL-DL configuration is a UL / DL configuration 2 as shown at 210, And ultimately by flexibly changing the transmission direction of subframes # 3 and # 8 from UL to DL to maximize radio spectrum efficiency, as shown at 310 and 315 of FIG. 3, respectively. The DL-reference UL / DL configuration is known by the Rel-12 UL / DL reconfigurable UE, which allows the UE to utilize flexible subframe resources. The UE also receives a hybrid automatic repeat request-acknowledgment (HARQ-ACK) timeline for physical dedicated shared channel (PDSCH) transmission according to the DL-reference UL / Can be determined appropriately. In this example, the DL-reference UL / DL configuration is assumed to be TDD UL / DL configuration 2. PDCCH 1 in subframe # 9 in radio frame n-1 for two PDCCH-UE1 and PDDCH 2 in subframe # 0 in radio frame n for UE2 in subframe # It can be seen that collision occurs in the same PUCCH 1a / 1b resource in UL subframe # 7. This is because the same number of the first control channel element (CCE) index, n _CCEm = 6, is used by the two PDCCHs and two different PDSCH HARQ timing relationships are assumed separately in UE1 and UE2. As a result, the implicitly mapped PUCCH resources are exactly the same in the two UEs according to the following equation:

Where n _CCEm is the number of the first CCE used for transmission of the corresponding PDCCH in the subframe. This is a common PUCCH resource conflict issue for all TDD UL / DL reconfiguration signaling methods. Two solutions are proposed to solve it.

In one embodiment, the PDSCH subframe is firstly classified into two types - Type 1 and Type 2. After the classification of the subframe, the PUCCH resource mapping is performed based on the DL subframe type. Additionally, in order to avoid excessive control overhead, an ARO (i.e., a HARQ-ACK resource offset field) may be used to compress the PUCCH region.

A solution to the PUCCH resource mapping scheme for UL-DL reconstruction supported by ReL-12, which aims at preventing impulse PUCCH resource mapping, is not yet known.

In one embodiment, the downlink sub-frame associated with the uplink sub-frame for HARQ-ACK feedback is determined according to the TDD UL / DL configuration included in the SIB1 message and the DL-reference UL / DL configuration indicated by the upper layer (I.e., Type 1 and Type 2) as follows: < RTI ID = 0.0 >

The Type 1 subframe is a DL subframe associated with UL subframe n for HARQ-ACK feedback according to the SIB1 TDD UL / DL configuration.

The Type 2 subframe is a DL subframe consisting of a two-step approach:

Step-1 : The Type 2 subframe includes a DL subframe associated with UL subframe n for HARQ-ACK feedback according to a DL-REFERENCE UL / DL configuration of a higher layer configuration to be. This configuration may be implicitly determined based on the TDD UL / DL configuration of two consecutive radio frames as documented in the previous IDF [1] or may be explicitly indicated by higher layer signaling.

Step-2 : If the Type 1 subframe overlaps with the Type 2 subframe configured in Step-1, the overlapping subframe will be further removed from the Type 2 subframe.

3, if the TDD configuration 1 is represented in SIB1 and the DL-reference UL / DL configuration is configuration # 2, then the Type 1 subframe is subdivided into subframes 305 in radio frame n And frames # 1 and 310 to # 0. On the other hand, the Type 2 subframe includes subframe # 3 at 320 in radio frame n and subframe # 9 at 325 in radio frame n-1.

Solution 1 : PUCCH format with Channel Selection (CS) lb. To solve the potential PUCCH resource conflict issue, one hybrid PUCCH resource mapping method includes the following. M identifies the downlink related set index K for TDD according to the DL-reference UL / DL configuration, as shown in 400 of FIG. Assume that the number of elements in set K as defined in Table 10.1.3.1-1 at 11. The set K is further divided into two sets: K ₁ and K ₂ , each of which consists of a number of sub-frames in the set K. The set K ₁ includes all type 1 subframes and the set K ₂ includes all type 2 subframes. M = M ₁ + M ₂ , where M ₁ and M ₂ represent the number of DL subframes in sets K ₁ and K ₂ , respectively.

가 DL-참조 UL/DL 구성에 따라 서브프레임 n-k_i로부터의 ACK/NACK/DTX 응답으로서 HARQ-ACK(i) 및 서브프레임 n-k_i로부터 유도되는 PUCCH 리소스를 나타낸다고 하자(여기서 k_i∈K이고, 0≤i≤M-1이다). j가 j=0에서부터 i 값의 증가하는 순서에서의 K₁ 내에서의 서브프레임 n-k_i의 위치를 나타낸다고 하고(여기서 0≤j≤M₁-1), l이 l=0으로부터 i 값의 증가하는 순서에서의 세트 K₂ 내에서의 서브프레임 n-k_i의 위치를 나타낸다고 하자(여기서, 0≤l≤M₂-1).

Denotes a PUCCH resource derived from HARQ-ACK (i) and subframe nk _i as an ACK / NACK / DTX response from subframe nk _i according to a DL-reference UL / DL configuration (where k _i ∈ K, 0? I? M-1). Let j denote the position of subframe nk _i in K ₁ in increasing order of i from j = 0 (where 0 ≤ j ≤ M ₁ -1), where l is the increment of i from l = 0 Let's denote the position of the sub-frame nk _i in the set of K ₂ in order to (wherein, 0≤l≤M ₂ -1).

Assuming that the SIB1 TDD UL / DL configuration is configuration 1 and the DL-reference UL / DL configuration is configuration 2, in one embodiment, the correspondence to DL subframes in set K associated with subframe 7 for HARQ- The values of j and l are shown at 500 in FIG. 5 with an example of a DL sub-frame indexed from set K ₁ at 510 to K ₂ at 515.

After the PDSCH subframe is indexed in the corresponding set, the PUCCH resource mapping is performed as follows: For the PDSCH transmission indicated by the detection of the PDCCH or the corresponding PDCCH indicating the downlink SPS release in subframe nk _i , And it corresponds to a type 1 sub-frame j (0 _< = j < = M &_lt;

This PUCCH format 1a / 1b resource for HARQ-ACK signal transmission in response to the legacy PDCCH-scheduled PDSCH may include introducing a 2 bit ARO (i.e., HARQ-ACK resource offset field) to prevent excessive control overhead , And by considering that the dynamic PUCCH format 1a / 1b resource space is often not fully exploited.

If M > 1, then DELTA _ARO is determined from the HARQ-ACK resource offset field in the DCI format of the corresponding EPDCCH as given in Table 1 at 600 in FIG.
