Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
It should be noted that; content of the present invention is suitable for but is not limited to transmission between base station described in the present invention and the described via node; transmission between the equipment of equipment of any similar described base station (as Home eNB, having the relaying of sub-district ID etc.) and similar described via node (as user's mobile communication equipment etc.) is all within protection scope of the present invention.
In the present invention, described PRB represents one or more Physical Resource Block.
As shown in Figure 2, be the repeated link uplink control channel resource distribution method flow chart of the embodiment of the invention, this method not only is suitable for TDD system and also is suitable for FDD system, may further comprise the steps:
Step S201, RN receives the higher level parameters N of eNB broadcasting PUCCH RNOr receive the R-PUCCH resource number that described eNB sends by high-level signaling.
In one embodiment of the invention, in a sub-district, the R-PUCCH resource of all RN correspondences can adopt public or exclusive mode to distribute, and common way is meant all RN total R-PUCCH resource in a resource area, and exclusive mode is meant that each RN distributes exclusive R-PUCCH resource.
When adopting common way to be RN distribution R-PUCCH resource, eNB can be to higher level parameters N of all RN broadcasting PUCCH RN, this parameter is used in reference to the original position of the R-PUCCH resource that is shown the RN distribution.
When adopting exclusive mode to be RN distribution R-PUCCH resource, eNB can pass through high-level signaling, sends its corresponding R-PUCCH resource number respectively as RRC (Radio Resource Control, Radio Resource control) signaling each RN in the sub-district.
Step S202, RN is according to higher level parameters N PUCCH RNOr the R-PUCCH resource number is determined corresponding R-PUCCH resource.
When adopting common way to be RN distribution R-PUCCH resource, RN receives higher level parameters N PUCCH RNAfter, RN determines that the R-PUCCH resource number is divided into following two kinds of situations:
Situation 1: if the downlink data that sends in the only corresponding repeated link descending sub frame of the ascending control information that sends in a repeated link sub-frame of uplink, then RN determines the R-PUCCH resource according to the method for the down definite PUCCH resource of fdd mode.Particularly,
For the FDD system, in subframe n, UE uses PUCCH resource n PUCCH (1)Transmitting HARQ-ACK.Wherein, in subframe n-4, for the PDCCH of PDSCH that the PDCCH indication is arranged or the release of indication SPS resource, resource number that UE uses is n PUCCH ( 1 ) = n CCE + N PUCCH ( 1 ) , Wherein, n CCEBe employed first CCE of corresponding DCI (Downlink Control Information, Downlink Control Information) (Control Channel Element, control channel unit) numbering, N PUCCH (1)Dispose by high level.In subframe n-4, for the PDSCH that does not have the PDCCH indication, then n PUCCH (1)Determine jointly by high level configuration and table 1.
Situation 2: if the downlink data that sends in the only corresponding a plurality of repeated link descending sub frames of the ascending control information that sends in a repeated link sub-frame of uplink, then RN determines the R-PUCCH resource according to the method for the down definite PUCCH resource of tdd mode.Particularly,
For the TDD system, two kinds of ACK/NACK feedback model: ACK/NACK bindings of high-rise support (bundling) and ACK/NACK multiplexing (multiplexing).
Bind for TDD ACK/NACK, will to belong to same code word in M the descending sub frame that in same sub-frame of uplink n, feeds back each independently the ACK/NACK feedback information (comprise PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) PDCCH (the Physical Downlink ControlChannel that ACK/NACK feedback and indication SPS resource discharge, Physical Downlink Control Channel) ACK/NAK feedback) carries out the logic add computing, obtain the feedback information of 1 or 2 bits, be the corresponding 1 bit feedback information of each code word, use PUCCH format 1a or format 1b to transmit accordingly.Wherein M is the number of elements of the K set of definition in the table 2.
Multiplexing for TDD ACK/NACK, when M＞1, in subframe n, then to carry out logic add, i.e. the corresponding 1 bit feedback information of each descending sub frame to the feedback information of a plurality of code words in the same descending sub frame.UE will be at the resource n among the subframe n PUCCH (1)The last PUCCHformat 1b transmission b (0) that selects based on channel that uses, b (1), b (0) wherein, the value of b (1) and resource number n PUCCH (1)The mapping relations of regulation obtain in the time of will be according to different M value.When b (0), when b (1) gets " N/A ", UE will not carry out the ACK/NACK feedback in subframe n.When M=1, in subframe n,, directly use PUCCH format 1a or PUCCH format 1b to transmit the ACK/NACK information of 1 bit or 2 bits with not carrying out the logic add operation of the feedback information of a plurality of code words in the same descending sub frame.
Multiplexing for the ACK/NACK of TDD system binding or ACK/NACK, during M=1, in subframe n, use PUCCH resource number n PUCCH (1)Transmitting HARQ-ACK.Wherein, (k ∈ K, K are the set { k that comprises M element at subframe n-k 0, k 1..., k M-1, the value of M is relevant with uplink-downlink configuration, and is as shown in table 1) in, if having the PDSCH of PDCCH (s) indication or the PDCCH that indication SPS resource discharges, at first { 0,1,2, N is satisfied in one of selection to UE among the 3} from set p≤ n CCE≤ N P+1The p value, wherein, n CCEBe subframe n-k mThe call number of middle employed first CCE of PDCCH, wherein, k mFor gathering the minimum value among the K and satisfying UE at subframe n-k mIn detected PDCCH.Definition

When adopting exclusive mode to be RN distribution R-PUCCH resource, RN directly determines corresponding R-PUCCH resource according to the R-PUCCH resource number, and this resource is that RN is exclusive, does not change in the some cycles.
When adopting common way to be RN distribution R-PUCCH resource, though the original position of the R-PUCCH resource of RN correspondence is disposed by high-level signaling, the original position of the PUCCH resource of dynamic dispatching UE correspondence is also disposed by high-level signaling, but the original position difference of high-level signaling notice, the resource location of the two is also inequality.
Below just the present invention is described in detail in the mode of specific embodiment, stipulated the relation between the R-PUCCH resource of the RN equipment correspondence PUCCH resource corresponding in these embodiments, thereby can avoid conflict between the two with the grand UE of dynamic dispatching.But need to prove that these embodiment only are optimal ways of the present invention, can not think that the present invention only can realize by following examples.
