Description

A kind of method and device of PUCCH resource mapping

Technical field

The present invention relates to the communications field, particularly a kind of method and device of PUCCH resource mapping.

Background technology

In LTE (Long Term Evolution) system, PDCCH (Physical Downlink Control Channel) sends in each wireless sub-frame, and forms TDM (time division multiplexing) relation with the PDSCH (Physical Downlink Shared Channel) of transmitting downlink data.Consult shown in Figure 1; PDCCH is through top n OFDM (the Orthogonal Frequency Division Multiplexing of a descending sub frame; OFDM) symbol sends; Wherein, The possible value of N is 1,2,3; 4, and N=4 only allows to appear in the system that system bandwidth is 1.4MHz.

Continuation evolution along with LTE-Advanced (Long Term Evolution of upgrading) standard; And COMP (Coordinated Multiple Point; Multipoint cooperative) transmission, enhancing MU-MIMO (Muti-User-MIMO; Multi-user's multiple-input and multiple-output) appearance of application scenarios such as; Making needs in the sub-district number of users of service to increase greatly, thereby to big leap ahead of capacity requirement of down control channel.For example; The a kind of of COMP possibly scene be RRH (the Remot Radio Head of a macro base station and a plurality of distributions; Remote Radio Unit) from constituting a sub-district in logic, then the number of users of the coverage of this sub-district and access all increases than original LTE system greatly; Simultaneously, the MU-MIMO of enhancing widely-used makes that the number of users of service increases greatly in the sub-district, therefore, the capacity of PDCCH is had higher requirement, and existing LTE PDCCH design can not be satisfied the demand.

The problem of and off-capacity resource-constrained for the PDCCH that mentions more than solving; Existing a solution is: consult shown in Figure 2; In the PDSCH zone in a descending sub frame be that unit sends the PDCCH that strengthens with PRB; Be called Enhanced PDCCH; As shown in Figure 2, traditional P DCCH is called Legacy PDCCH.

To the structure of above-mentioned Enhanced PDCCH, the search volume design of a kind of resource based on Enhanced PDCCH bunch is arranged at present, be about to a plurality of continuous PRB to dividing cluster into, be called Enhanced PDCCH cluster.For example, consult Fig. 3 and shown in Figure 4, preferable, comprise that 4 PRB are right in the Enhanced PDCCH cluster, the PDCCH of UE can only transmit in one bunch.Can only transmit the PDCCH of a UE in one bunch, also can transmit the PDCCH of a plurality of UE.UE transmits the PRB position that PDCCH occupied in one bunch relevant with the polymerization grade, and UE is according to predefine rule or according to the configuration information of base station, the resource of confirming in a sub-frame, to be monitored bunch.

For LTE FDD (LTE Frequency Division Duplexing (FDD)) system, UE after accomplishing demodulation to the data on the descending sub frame n-4, decoding, the signaling that will whether need retransmit in the data on this descending sub frame of base station feedback on the sub-frame of uplink n, i.e. feeding back ACK/nack message.

For the LTETDD(LTE time division duplex) system; UE possibly feed back the pairing ACK/NACK information of a plurality of descending sub frames in a sub-frame of uplink; Be UE after having accomplished demodulation to the data on the descending sub frame n-k, decoding; The signaling that will whether need retransmit in the data on this descending sub frame of base station feedback on the sub-frame of uplink n; It is feeding back ACK/nack message; Wherein, K ∈ K; The value of set K is numbered relevant with the uplink-downlink configuration of system and concrete subframe; Specifically as consulting shown in the table 1, a plurality of descending sub frames that wherein corresponding same sub-frame of uplink carries out the ACK/NACK feedback abbreviate " feedback window " hereinafter as:

Table 1 K: { k ₀, k ₁, Λ k _M-1For TDD

Wherein, M is the maximum occurrences of K,, can in sub-frame of uplink, feed back the maximum number of the descending sub frame of corresponding ACK/NACK information that is.In addition, a plurality of radio frames sequence arrangement, even last subframe is k among the radio frames a; Then first subframe is k+1 among the radio frames a+1; Table 1 with a radio frames be example provided each sub-frame of uplink for the situation of K, wherein, descending sub frame in the last radio frames of expression of n-k＜0.

In the LTE system; Be used to carry out the pairing ACK/NACK information of PDSCH of descending dynamic dispatching or during the pairing ACK/NACK information of the PDCCH that is used to indicate SPS (semi-continuous scheduling) resource to discharge in feedback, the transformat of the PUCCH resource that adopts is PUCCH format 1a/1b usually in feedback on PUCCH (Physical Uplink Control Channel) resource.In the above scenario, PUCCH resource number is denoted by

This number is based on the resources occupied by the PDCCH CCE (Control? Channel? Element, the control channel element) to determine the number, usually the maximum number of PDCCH resources is much smaller than the number of users within the cell , and performs the PDCCH resources -> PUCCH resource mapping, so that the system as long as the maximum dynamic PUCCH resources reserved for an amount equal to the maximum number of PDCCH resources, without the need for the maximum number of users within the cell for PUCCH resource reservation , this design can effectively reduce the system the number of PUCCH resources reserved in, can effectively guarantee Enhanced? PDCCH dynamic scheduling of system efficiency.

In determining the number of PUCCH resources

after, UE can be determined according to the number

to determine the appropriate PUCCH resources, including: determining when used for PUCCH transmission OC (orthogonal) sequence number, CS (cyclic shift) sequence number and occupied PRB (physical resource block) number, which, in accordance with the provisions TS36.211, determine the amount of each of the above parameters as follows:

The OC sequence numbering confirms that mode is following:

The CS sequence numbering confirms that mode is following:

Wherein,

$c=\left\{\begin{array}{cc}3& \mathrm{normal\; cp}\\ 2& \mathrm{extended\; cp}\end{array}\right.$

On time slot 0,

$n_{\tilde{p}}^{\&prime;}\left(n_s\right)=\left\{\begin{array}{cc}{n}_{\mathrm{PUCCH}}^{(1,\tilde{p})}& \mathrm{if}{n}_{\mathrm{PUCCH}}^{(1,\tilde{p})}<c\&CenterDot;N_{\mathrm{cs}}^{\left(1\right)}/{\mathrm{\&Delta;}}_{\mathrm{shift}}^{\mathrm{PUCCH}}\\ (n_{\mathrm{PUCCH}}^{(1,\tilde{p})}-c\&CenterDot;N_{\mathrm{cs}}^{\left(1\right)}/{\mathrm{\&Delta;}}_{\mathrm{shift}}^{\mathrm{PUCCH}})\mathrm{mod}(c\&CenterDot;N_{\mathrm{sc}}^{\mathrm{RB}}/{\mathrm{\&Delta;}}_{\mathrm{shift}}^{\mathrm{PUCCH}})& \mathrm{otherwise}\end{array}\right.$

On the time slot 1,

$h_{\tilde{p}}=(n_{\tilde{p}}^{\&prime;}(n_s-1)+d)\mathrm{mod}({\mathrm{cN}}^{\&prime;}/{\mathrm{\&Delta;}}_{\mathrm{shift}}^{\mathrm{PUCCH}}),$

During routine CP, d=2, during expansion CP, d=0,

for the cyclic shift interval configured by higher layers.

Yet the public technology of prior art has only provided relevant processing scheme to traditional PD CCH resource-PUCCH resource mapping, not to strengthening PDCCH->the PUCCH resource mapping provides concrete processing scheme.

Embodiment

In communication system, when adopting Enhanced PDCCH, the quantity for the PUCCH resource reserved in the system of effectively reducing in the embodiment of the invention, provides a kind of PUCCH resource mapping method to Enhanced PDCCH.Be specially: resource allocation information is set; This resource allocation information is used to indicate the corresponding PUCCH resource of each E-PDCCH cluster of system configuration; UE and base station are respectively according to this resource allocation information; Confirm each self-corresponding at least one PUCCH resource of each E-PDCCH cluster of system configuration, and have the corresponding PUCCH transmitted over resources UCI of E-PDCCH cluster of PDCCH transmission.

In the embodiments of the invention; The corresponding UCI of PDCCH can only adopt a PUCCH resource to send; Also can adopt a plurality of PUCCH resources to send; Promptly PDCCH can corresponding at least one PUCCH resource; As; PDCCH can only corresponding PUCCH resource, also can corresponding two and above PUCCH resource.

Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.

Consult shown in Figure 5ly, have several base stations and UE in the embodiment of the invention, downlink signaling can be sent to UE through Enhanced PDCCH in the base station, and is corresponding, and UE need confirm that the corresponding PUCCH resource of Enhanced PDCCH is to feed back corresponding UCI.

Consult shown in Figure 6ly, in the embodiment of the invention, it is following that UE carries out the detailed process of PUCCH resource mapping:

Step 600:UE confirms to be configured in N Enhanced PDCCHcluster in the descending sub frame in the system, abbreviates E-PDCCH cluster as, and wherein, N is a positive integer, and N >=1.

UE can confirm to be configured in the system above-mentioned N E-PDCCH cluster in the descending sub frame according to the notice of network side when access network.

Step 610:UE receives the resource allocation information that send the base station, and this resource allocation information is used to indicate the corresponding PUCCH resource of E-PDCCH cluster of system configuration.

In the present embodiment, any one E-PDCCH cluster can map to one or more PUCCH resource, and the numbering of the above-mentioned resource allocation information PUCCH resource that promptly to be each E-PDCCH cluster of system configuration corresponding.In the practical application; The resource allocation information that the base station is provided with to different UEs can be identical or different; When being the base station to the identical E-PDCCH cluster of different UEs configuration; For different UE; The numbering of the identical pairing PUCCH resource of E-PDCCH cluster can be identical, also can be inequality.

Step 620:UE is according to the resource allocation information that obtains; Confirm in N E-PDCCHcluster each descending sub frame in M descending sub frame of system configuration the numbering of K corresponding PUCCH resource respectively; Wherein, M and K are positive integers; M >=1; K >=1, and M descending sub frame uses the corresponding uplink control signal of same sub-frame of uplink transmission.

For LTE FDD system, M=1, for LTE TDD system, the value of M and TDD uplink-downlink configuration and concrete sub-frame of uplink are relevant.

When performing step 620, UE determines the number of PUCCH resources, the resources will be further based on the number of PUCCH determined PUCCH transmission spreading sequence number and the corresponding physical resource block number in which, in determining the spreading sequence numbering, UE used

(cyclic shift interval) can be configured by the base station, may be constant is 1.

Step 630:UE is configured in system and carries out the PDCCH detection among a N in the descending sub frame E-PDCCH cluster, confirms to exist the E-PDCCH cluster of PDCCH transmission.

UE detects through PDCCH, confirms network side has carried out the PDCCH transmission on which E-PDCCH cluster, and is corresponding, and UE will carry out up feedback on the corresponding PUCCH resource of the E-PDCCH cluster that has the PDCCH transmission.

Step 640:UE is on the corresponding PUCCH resource of the E-PDCCH cluster that has the PDCCH transmission, to the corresponding UCI of base station transmits (Uplink Control Signal, uplink control signal).

In the foregoing description, the PDCCH that on any one E-PDCCH cluster, transmits can be the PDCCH that is used to dispatch the PDSCH transmission, also can be to be used to indicate the PDCCH that discharges descending SPS.Whether and the UCI that UE sends on the corresponding PUCCH resource of any one E-PDCCH cluster can be used to dispatch the PDCCH of PDSCH transmission in order to indication, perhaps, be used to indicate the PDCCH that discharges descending SPS correctly to receive.

In the above-described embodiments, according to the difference of actual application environment, the executive mode of step 620 is also inequality, specifically can be divided into but is not limited to following two kinds of situation:

First kind of situation is: UE to N E-PDCCH cluster of system configuration, confirms the numbering of a corresponding PUCCH resource respectively, i.e. K=1 according to preset resource allocation information in each subframe in M descending sub frame.Be specially:

Resource allocation information comprises N E-PDCCH cluster of system configuration, the numbering of a PUCCH resource of difference correspondence in each subframe in M descending sub frame.Accordingly, UE can directly confirm the numbering of a PUCCH resource of difference correspondence in each E-PDCCH cluster each subframe in M descending sub frame according to the resource allocation information that obtains; Perhaps,

Resource allocation information comprises N E-PDCCH cluster of system configuration, the numbering of a PUCCH resource of difference correspondence in the sub-frame in M descending sub frame.Accordingly; UE can be according to the resource allocation information that obtains; Confirm the numbering of each self-corresponding PUCCH resource in the sub-frame of N E-PDCCH cluster in M descending sub frame of system configuration respectively; According to the numbering of acquired N PUCCH resource, confirm the numbering of the PUCCH resource that corresponding E-PDCCH cluster difference in other M-1 sub-frame is corresponding according to preset rule again; Perhaps,

Resource allocation information comprises an E-PDCCH cluster among N the E-PDCCH cluster of system configuration, the numbering of a corresponding PUCCH resource respectively in each subframe in M descending sub frame.Accordingly; UE can be according to the resource allocation information that obtains; Confirm the numbering of a PUCCH resource of difference correspondence in an above-mentioned E-PDCCH cluster each subframe in M descending sub frame; According to the numbering of acquired M PUCCH resource, confirm the numbering of a PUCCH resource of difference correspondence in other N-1 E-PDCCH cluster each subframe in M descending sub frame according to preset rule again; Perhaps,

Resource allocation information comprises an E-PDCCH cluster among N the E-PDCCH cluster of system configuration, the numbering of a corresponding PUCCH resource in the sub-frame in M descending sub frame.Accordingly; UE can be according to the resource allocation information that obtains; Confirm the numbering of corresponding in the sub-frame of an above-mentioned E-PDCCH cluster in a M descending sub frame PUCCH resource; Again according to the numbering of an acquired PUCCH resource, confirm each self-corresponding PUCCH resource in N E-PDCCH cluster each subframe in M descending sub frame of system configuration according to preset rule.

Down to adopt embodiment a and embodiment b respectively the concrete executive mode of first kind of situation to be described in detail.

Embodiment a; In LTE FDD system; M=1; Be that UE need carry out the UCI feedback to the PDCCH that in a descending sub frame, receives in a sub-frame of uplink; In such cases; When execution in step 620, UE needs according to preset resource allocation information, and each the E-PDCCH cluster to system configuration confirms a corresponding PUCCH resource respectively;

For example, disposed N E-PDCCH cluster in the supposing the system, its numbering is respectively E-PDCCH-1; E-PDCCH-2 ..., E-PDCCH-N; Simultaneously, the numbering of corresponding PUCCH resource is respectively PUCCH-1, PUCCH-2; ...; PUCCH-N, so, if UE confirms in the E-PDCCH-n of descending sub frame, to exist the PDCCH transmission; What then UE confirmed PUCCH resource that this PDCCH transmission is corresponding is numbered PUCCH-n, wherein 1≤n≤N.Here, N a number of PUCCH resources PUCCH-1, PUCCH-2, ..., PUCCH-N entails between each number can be the same or different from each other or in part, all the same; Further, the transmission format PUCCH resources can is 3GPPE-UTRA defined PUCCH? format? 1a/1b.

In the foregoing description a, the resource allocation information that UE receives from the base station can comprise the numbering of the corresponding PUCCH resource of each E-PDCCH cluster of system configuration, is specially:

Mode one, in resource allocation information, explicitly disposes a PUCCH resource to N E-PDCCH cluster of system configuration respectively; As, to any one E-PDCCH cluster, notify this E-PDCCH cluster the numbering of a pairing PUCCH resource.

So, when execution in step 620, UE can directly confirm the numbering of each each self-corresponding PUCCH resource of E-PDCCH cluster of system configuration according to the resource allocation information that obtains.

Mode two; In resource allocation information; Explicitly has disposed a PUCCH resource to an E-PDCCH cluster among N the E-PDCCH cluster, and confirms the PUCCH resource that other N-1 E-PDCCH cluster are corresponding based on a PUCCH resource that has disposed through presetting method.

For example, suppose explicit configuration in the resource allocation information first PUCCH resource be numbered x1, being numbered of the PUCCH resource that E-PDCCH cluster n is corresponding: x (n)=x1+ (n-1), wherein 1≤n≤N then;

Again for example; Suppose explicit configuration in the resource allocation information a PUCCH resource be numbered x1; Then the PUCCH resource that E-PDCCH cluster n is corresponding is numbered x (n)=x1+ (n-1) * Δ; Δ＞1 wherein; 1≤n≤N; The value of Δ can be fixing or agreement, perhaps, also can be configured by the base station.

So; When execution in step 620; UE can confirm a corresponding PUCCH resource to an E-PDCCH cluster earlier according to the resource allocation information that obtains, and confirms each self-corresponding PUCCH resource of other N-1 E-PDCCH cluster according to an acquired PUCCH resource again.

Embodiment b: in LTE TDD system, M >=1, UE need carry out the UCI feedback to the PDCCH that in M descending sub frame, receives in same sub-frame of uplink, specifically as shown in table 1; In such cases; When execution in step 620; UE needs according to preset resource allocation information; N E-PDCCH cluster to system configuration; Confirm a PUCCH resource in each subframe in the M sub-frame respectively, i.e. respectively corresponding PUCCH resource in any one E-PDCCH cluster each subframe in the M sub-frame.

For example; Disposed N E-PDCCH cluster in the supposing the system; Its numbering is respectively E-PDCCH-1, E-PDCCH-2 ...; E-PDCCH-N; Simultaneously, suppose any one E-PDCCH cluster, be designated as E-PDCCH-n (1≤n≤N); The numbering of corresponding respectively PUCCH resource is followed successively by PUCCH-n-1 in each subframe in the M sub-frame; PUCCH-n-2 ..., PUCCH-n-M; Wherein, PUCCH-n-m (1≤n≤N, 1≤m≤M) represent the corresponding PUCCH resource of PDCCH that E-PDCCH-n transmits in the m sub-frame, so; If UE confirms in subframe m; In E-PDCCH-n, have the PDCCH transmission, then UE confirms that the corresponding PUCCH resource of this PDCCH transmission is PUCCH-n-m, wherein; 1≤n≤N, 1≤m≤M.

Here N * M a PUCCH resource numbers PUCCH-n-1, PUCCH-n-2, ..., PUCCH-nM entails

between each number can be the same or different from each other or in part, all the same; Further, the PUCCH resources, transport format can be 3GPP? E-UTRA defined PUCCH? format? 1a/1b.

On the other hand; For some TDD ascending-descending subframes configuration; The descending sub frame number of the required feedback of different sub-frame of uplink UCI is different; Promptly the M value for different sub-frame of uplink is different; For example; TDD UL-DL configuration 1 or 3 in the table 1, at this moment, network side can the maximum according to the corresponding a plurality of M values of different sub-frame of uplink dispose the corresponding PUCCH resource of E-PDCCH cluster in resource allocation information.

In the foregoing description b, the resource allocation information that UE receives from the base station can comprise the numbering of corresponding in each E-PDCCH cluster each subframe in the M sub-frame of a system configuration PUCCH resource, is specially:

Mode one, in resource allocation information, explicitly disposes the numbering of a PUCCH resource respectively in each subframe in the M sub-frame to N E-PDCCH cluster of system configuration; For example, to any one E-PDCCH cluster, notify the numbering of a PUCCH resource of difference correspondence in this E-PDCCH cluster each subframe in the M sub-frame.

Accordingly, when execution in step 620, UE will be directly to confirming a corresponding PUCCH resource respectively in each E-PDCCH cluster each subframe in the M sub-frame that exists PDCCH to transmit.

Mode two; In resource allocation information; Explicitly is to the numbering that disposes a PUCCH resource in the sub-frame of N E-PDCCH cluster in the M sub-frame of system configuration respectively, and respectively based on the numbering of the N that has disposed the corresponding E-PDCCH cluster of PUCCH resource distribution PUCCH resource of correspondence in other M-1 sub-frame.

For example; N the E-PDCCH cluster that supposes explicit configuration in the resource allocation information in a sub-frame corresponding PUCCH resource be numbered x (n); Then n E-PDCCH cluster in the m sub-frame corresponding PUCCH resource be numbered x (n; M)=x (n)+(m-1); 1≤n≤N wherein, 1≤m≤M.

Again for example; N the E-PDCCH cluster that supposes explicit configuration in the resource allocation information in a sub-frame corresponding PUCCH resource be numbered x (n); Then n E-PDCCH cluster corresponding PUCCH resource sequence number in the m sub-frame is x (n; M)=x (n)+(m-1) * Δ; 1≤n≤N wherein, 1≤m≤M, Δ are positive integer; The value of Δ can be fixing or agreement, also can be configured by the base station.

So; When execution in step 620; UE can be according to the resource allocation information that obtains; The numbering of each self-corresponding PUCCH resource in the sub-frame of N E-PDCCH cluster in the M sub-frame of first definite system configuration respectively confirms that according to the numbering of acquired N PUCCH resource corresponding E-PDCCH cluster distinguishes the numbering of a corresponding PUCCH resource in other M-1 sub-frame again.

Mode three; In preset resource allocation information; Explicitly is to the numbering that disposes a PUCCH resource in an E-PDCCH cluster each subframe in the M sub-frame respectively; Then, dispose the numbering of a PUCCH resource of difference correspondence in other each E-PDCCH cluster each subframe in the M sub-frame more respectively based on the numbering of each the PUCCH resource that has disposed.

For example; Suppose that first E-PDCCH cluster of configurations shown corresponding PUCCH capital in the m sub-frame is numbered x (m) in the resource allocation information; Then n E-PDCCH cluster corresponding PUCCH resource sequence number in the m sub-frame is x (n; M)=x (m)+(n-1); 1≤n≤N wherein, 1≤m≤M.

Again for example; Suppose that first E-PDCCH cluster of configurations shown corresponding PUCCH capital in the m sub-frame is numbered x (m) in the resource allocation information; Then n E-PDCCH cluster corresponding PUCCH resource sequence number in the m sub-frame is x (n; M)=x (m)+(n-1) Δ; 1≤n≤N wherein, 1≤m≤M, Δ are positive integer; The value of Δ can be fixing or agreement, also can be configured by the base station.

So; When execution in step 620; UE can be according to the resource allocation information that obtains; Confirm the numbering of corresponding in an E-PDCCH cluster each subframe in a M sub-frame PUCCH resource earlier, confirm each self-corresponding PUCCH resource in other N-1 E-PDCCHcluster each subframe in M descending sub frame according to the numbering of acquired M PUCCH resource again.

Mode four; In preset resource allocation information; Explicitly is to the numbering of a PUCCH resource of configuration in the sub-frame of an E-PDCCH cluster in the M sub-frame; Then, dispose the numbering of each self-corresponding PUCCH resource in each E-PDCCH cluster each subframe in M descending sub frame more respectively based on the numbering of a PUCCH resource that has disposed.

For example; Suppose the x1 that is numbered of explicitly in the resource allocation information for a PUCCH resource of first E-PDCCH cluster configuration; E-PDCCH cluster n being numbered of a corresponding PUCCH resource in subframe m then: x (n; M)=x1+ (m-1) * N+ (n-1); Perhaps, and x (n, m)=x1+ (n-1) * M+ (m-1); 1≤n≤N wherein, 1≤m≤M.

Again for example; Suppose the x1 that is numbered of explicitly in the resource allocation information for a PUCCH resource of first E-PDCCH cluster configuration; Then the PUCCH resource that the PDCCH of E-PDCCH cluster n in subframe m is corresponding is numbered x (n; M)=x1+ (m-1) * N* Δ 1+ (n-1) * Δ 2; Perhaps; X (n; M)=x1+ (n-1) * M* Δ 1+ (m-1) * Δ 2; Wherein 1 ,≤n≤N, 1≤m≤M; Δ 1 is a positive integer with Δ 2; The value of Δ 1 and Δ 2 can be fixing or agreement, also can be configured by the base station, and the value of Δ 1 and Δ 2 can be identical or different.

So; When execution in step 620; UE can be according to the resource allocation information that obtains; Confirm earlier corresponding in the sub-frame of an E-PDCCH cluster in a M sub-frame PUCCH resource, confirm each self-corresponding PUCCH resource in N E-PDCCH cluster each subframe in M descending sub frame of system configuration according to an acquired PUCCH resource again.

Second kind of situation is: UE to each E-PDCCH cluster of system configuration, confirms K PUCCH resource according to preset resource allocation information respectively in each subframe in M descending sub frame.Wherein, K＞1, preferable, K can be defined as the number that network side adopts the descending carrier of the corresponding PDCCH of E-PDCCH cluster place descending carrier transmission.Be specially:

Resource allocation information comprises N E-PDCCH cluster of system configuration, the numbering of K PUCCH resource of difference correspondence in each subframe in M descending sub frame.Accordingly, UE can directly distinguish the numbering of K corresponding PUCCH resource according to the resource allocation information that obtains in each E-PDCCH cluster each subframe in M descending sub frame of definite system configuration; Perhaps,

Resource allocation information comprises N E-PDCCH cluster of system configuration, the numbering of a PUCCH resource of difference correspondence in the sub-frame in M descending sub frame.Accordingly; UE can be according to the resource allocation information that obtains; Confirm corresponding respectively in each E-PDCCH cluster each subframe in M descending sub frame of a system configuration PUCCH resource; And, confirm other K-1 corresponding respectively in corresponding E-PDCCH cluster each subframe in M sub-frame PUCCH resources according to acquired each PUCCH resource; Perhaps,
