Embodiment one
UE can send a plurality of types of ascending control informations (UCI) in up direction, for example, period CSI (P-CSI), Scheduling request (SR) and HARQ-ACK information.PUCCH format for carrying different types of UCI is generally different.It is above-mentioned PUCCH resource can be defined on some or all of upgoing O S in a TU, alternatively, above-mentioned PUCCH resource can also It is defined on multiple TU, to increase covering.Dependent on the uplink and downlink structure of TU, can be used for carrying PUCCH in a TU OFDM symbol (OS) number of resource can be variation.For example, one TU of note includes 7 OS, a TU can be entirely used for Uplink is 7 to the OS numbers of PUCCH resource；One TU can be comprising descender region for sending PDCCH, and And remainder is used for uplink, it is assumed that 2 OS are for carrying PDCCH, then the OS numbers of PUCCH resource are 5.To passing through code point (CDM) is multiplexed the case where being multiplexed multiple PUCCH channels on unit running time-frequency resource, such as a PRB of a TU, as a TU Can also be to become in the PUCCH channel numbers that above-mentioned unit running time-frequency resource can be multiplexed when the variation of the OS numbers of interior PUCCH resource Change.
To a PUCCH format, it is assumed that all define PUCCH resource, base on all PRB that can be used for PUCCH transmission The PUCCH resource actually distributed in which PRB of standing is realized by base station to be determined.Note is multiplexed in an above-mentioned unit running time-frequency resource PUCCH resource number is A, and the PRB that can be used for PUCCH transmission can divide B above-mentioned unit running time-frequency resources, then support PUCCH resource sum is A × B, index rangeFor example, in LTE system, to PUCCH lattice Formula 3 can be multiplexed 5 channels in a PRB, then correspond to 110 PRB of maximum bandwidth, and the index of 3 resource of PUCCH format can be with It is from 0 to 549.According to analysis above, when being used for the OS numbers variation of PUCCH transmission in a TU, in above-mentioned unit time-frequency The PUCCH channel numbers that can be multiplexed in resource can also be variation, such as become a from A, the PUCCH that at this moment can be supported Total number resource correspondingly becomes a × B, index rangeTo the OS numbers transmitted applied to PUCCH Different value, can be predefined in the PUCCH resource number of an above-mentioned unit running time-frequency resource multiplexing, can be according to It is calculated in the OS numbers of PUCCH transmission, or can be configured with high-level signaling.For a UE, its distribution is remembered PUCCH resource index be n, the index n of above-mentioned distribution can not the variation with the OS numbers variation transmitted for PUCCH.Using This method is then constantly present the PUCCH resource for distributing to this UE as long as meeting n≤min (A × B-1, a × B-1).As long as Base station scheduling ensures that the PUCCH resource index n of each UE distribution does not conflict, then when the OS numbers variation transmitted for PUCCH, point The PUCCH resource matched still does not conflict.
To a PUCCH format, when the variation of the OS numbers of PUCCH resource in a TU, in above-mentioned unit running time-frequency resource The PUCCH channel numbers that can be multiplexed can also be variation.To different PUCCH formats, the PUCCH channels of above-mentioned multiplexing Several variation ratios may be different.As shown in Fig. 3 (a), it is assumed that distribute b PRB since PRB indexes 0 and be used for PUCCH lattice 1 channel of formula, and followed by several 2 channels of PUCCH format are assigned with from PRB indexes b.Because of the resource of two kinds of PUCCH formats It is the continuous PRB of distribution, so the regions PUCCH are continuous, surplus resources are to be used for data transmission.As shown in Fig. 3 (b), when In one TU when the variation of the OS numbers of PUCCH resource, it is assumed that the variation ratio of the PUCCH resource number of two kinds of PUCCH formats multiplexing Example is identical, for example, all halving, then, in order to carry equal number of PUCCH resource, occupying the increased coefficient of PRB number is all 2.It needs 2b PRB of distribution to be used for PUCCH format 1, and is used for PUCCH format 2 since PRB indexes 2b.Because two kinds The resource of PUCCH format is still the continuous PRB of distribution, so the regions PUCCH are continuous, surplus resources are passed for data It is defeated.As shown in Fig. 3 (c), when the variation of the OS numbers of PUCCH resource in a TU, it is assumed that two kinds of PUCCH formats are in a PRB The variation ratio of the PUCCH resource number of interior multiplexing is different, for example, 2/3 and 1/3, then, in order to carry equal number of PUCCH Resource, the increased coefficient of PRB number that PUCCH format 1 occupies is 1.5, and the increased system of PRB number that PUCCH format 2 occupies Number is 3.The PRB number that PUCCH format 1 occupies is about 1.5b, and PUCCH format 2 is used for since PRB indexes 3b, two kinds There is the interval for being about 1.5b PRB among PUCCH format.The PRB at this part interval is used for the PRB of data channel not with other Continuously, to affect the flexibility ratio of resource allocation.
Analysis according to fig. 3, when the variation of the OS numbers of PUCCH resource in a TU, it is assumed that two kinds of PUCCH formats are one The variation ratio for the PUCCH resource number being multiplexed in a PRB is different, if being independently determined PUCCH moneys according to each PUCCH format The running time-frequency resource of source mapping, may cause the fragment of data channel.
In order to avoid the above situation needs adjustment PUCCH resource to reflect when the variation of the OS numbers of PUCCH resource in a TU When the running time-frequency resource penetrated, the starting point for being mapped to channel of second of PUCCH format is according to the letter of the mapping of the first PUCCH format The terminal in road determines.For example, remember that the last one PUCCH resource of the first PUCCH format is mapped to PRB x, then second The PUCCH resource of PUCCH format should be mapped since PRB x or x+1, to avoid fragment.It can be with according to above-mentioned starting point Determine that the index of the second PUCCH format is 0 PUCCH resource.
Alternatively, parameter can be configured with high-level signalingWhen the variation of the OS numbers of PUCCH resource in a TU, root According to above-mentioned OS numbers L and parameter for PUCCHObtain parameterParameterIt can indicate the first PUCCH format The starting PRB of the end PRB of mapping, the mapping of second of PUCCH format can be next PRB of above-mentioned end PRB；Alternatively, It can also indicate that the starting PRB of second of PUCCH format mapping.Above-mentioned starting PRB includes that the index of the second PUCCH format is 0 PUCCH resource.For example, according to the OS number L for PUCCH of a TU, the reference value of the OS numbers for PUCCH resource is L0, can obtain the PUCCH resource number of first PUCCH format being multiplexed in a PRB variation ratio be p=f (L, L0), for example, p=L/L0, alternatively, according to the PUCCH of the OS numbers of corresponding PUCCH being multiplexed on an above-mentioned unit running time-frequency resource Resource number calculates ratio p.Further, according to ratio p and parameterObtain parameterFor example,Or
Can be the offset for configuring PUCCH resource index alternatively, to a kind of PUCCH format It relies on In the OS numbers for carrying a PUCCH resource.Can be the OS of the carrying PUCCH resource different to each to a kind of PUCCH format Number is all respectively configuredAlternatively, can also be the OS numbers grouping to PUCCH resource, for example, every group includes similar in some OS numbers, and every group of OS number is respectively configuredAssuming that the PUCCH resource of high-level signaling configuration indexes n, in a TU The PUCCH resource of actual disposition UE indexesAssuming that the mechanism based on ARI indicates PUCCH resource, believed with high level It enables and configures N number of PUCCH resource, ARI is used in combination to indicate one of above-mentioned N number of PUCCH resource.Remember that above-mentioned N number of PUCCH resource is nk, k= 0,1 ... N-1, then the PUCCH resource of the actual disposition UE in a TU, which indexes, isUsing this method, PUCCH resource index 0 can be that fixation is mapped to a PRB, such as PRB indexes 0.
Embodiment two
To the downlink data transmission based on HARQ, UE can be fed back by PUCCH resource after receiving downlink data HARQ-ACK information.In addition, UE is also needed to through PUCCH resource to base station report period CSI (P-CSI) information.Above-mentioned PUCCH Resource can be defined on some or all of upgoing O S in a TU, alternatively, above-mentioned PUCCH resource can also be definition On multiple TU, to increase covering.Dependent on the uplink and downlink structure of TU, it can be used for carrying PUCCH resource in a TU OFDM symbol (OS) number can be variation.For example, one TU of note includes 7 OS, a TU can be entirely used for uplink biography It is defeated, it is 7 to the OS numbers of PUCCH resource；One TU can be comprising a descender region for sending PDCCH, and residue Part is used for uplink, it is assumed that 2 OS are for carrying PDCCH, then the OS numbers of PUCCH resource are 5.Carrying certain uplink Can correspondingly increase when the reduction of the OS numbers of PUCCH resource in a TU in the case of controlling information UCI payloads The PRB number that PUCCH resource occupies, to ensure the transmission performance of PUCCH resource.
To each PUCCH resource, the PRB resources of PUCCH occupancy can be configured, for example, the starting that PUCCH resource occupies PRB and the PRB number continuously occupied, furthermore it is also possible to configure the other parameters of PUCCH resource.Or, it is assumed that a PUCCH PRB number of resource occupation is fixed, such as 1 PRB can be root when changing for carrying the OS numbers of PUCCH resource According to the variation of the multiplexing PUCCH resource number in a PRB, the PRB sums for carrying PUCCH resource correspondingly change. Assuming that there are a variety of PUCCH formats, the payload bit number that above-mentioned a variety of PUCCH formats can carry is different.Above-mentioned multiple PUCCH Format may include being mapped to the fewer PUCCH of OS numbers, for example, 1 or 2 OS, referred to as short PUCCH；Be mapped to OS The more PUCCH of number, for example, being more than or equal to 4 OS, referred to as long PUCCH.Alternatively, above-mentioned multiple PUCCH formats can also be only Refer to the different-format of long PUCCH.The OS numbers of above-mentioned a variety of PUCCH formats can all be variable, alternatively, can also be a part The OS data of PUCCH format are variable, and the OS data of another part PUCCH format are fixed.For example, the PUCCH lattice in LTE The carrying of formula 3 is less than or equal to 22 bits, and PUCCH format 4 can carry more bits, to be selected according to the bit number of UCI It selects PUCCH format 3 or PUCCH format 4 is used for transmission UCI.
Can be the mechanism instruction PUCCH resource based on ARI to the downlink data transmission based on HARQ.That is, passing through high level The set of alternative PUCCH resource is configured, and is provided come a PUCCH in the above-mentioned set of dynamic instruction by ARI in PDCCH Source.The method that the PUCCH resource of present invention configuration ARI instructions is described below.
The method of the first configuration PUCCH resource is, unrelated with the carrying OS numbers of PUCCH resource, and N is configured with high-level signaling Then a PUCCH resource adjusts N number of PUCCH resource of above-mentioned configuration according to the OS numbers for PUCCH.N-th of note configuration The starting PRB indexes of PUCCH resource are Sn, it is R to occupy PRB numbern, n=0,1 ..., N-1 remember and are currently used in PUCCH resource OS numbers be L, then n-th of PUCCH resource of above-mentioned configuration can be adjusted to from starting PRB indexes SnStart continuous occupancy R'n= f(Rn,L,L0) a PRB, L0It is to refer to OS numbers.For example, it is assumed that PUCCH resource is mapped in a TU, and assume a TU packet Containing 7 OS, L07 can be equal to,OrIt, can be with when there are multiple PUCCH formats It is that PUCCH resource is respectively configured to each PUCCH format.When OS number of the basis for PUCCH adjusts the N number of of above-mentioned configuration PUCCH resource, the payload bit number that above-mentioned N number of PUCCH resource can carry correspondingly change, and are suitble to the PUCCH lattice of UCI transmission Formula is it can also happen that variation.I.e., it is possible to be the PUCCH lattice that the OS numbers determination according to UCI bit numbers and for PUCCH needs to use Formula, and then determine available N number of PUCCH resource.ARI indicates one of above-mentioned N number of PUCCH resource.
The method of second of configuration PUCCH resource is, according to the different situations of the OS numbers of carrying PUCCH resource, to use respectively High-level signaling configures one group of PUCCH resource, and every group of PUCCH resource includes N number of PUCCH resource.Can be different to each Above-mentioned one group of PUCCH resource is all respectively configured in the OS numbers of PUCCH resource, alternatively, can also be the OS numbers point to PUCCH resource For example, every group includes some similar OS numbers, and above-mentioned one group of PUCCH resource is respectively configured to every group of OS number in group.It is more when existing Can be that PUCCH resource is respectively configured to each PUCCH format when a PUCCH format.According to the OS numbers for carrying PUCCH It determines the payload bit number that can be carried of the PUCCH resource of each PUCCH format, the PUCCH format of UCI transmission is suitble to also may be used It can change.I.e., it is possible to be the PUCCH format that the OS numbers determination according to UCI bit numbers and for PUCCH needs to use.Root Corresponding one group of PUCCH resource is obtained according to the OS numbers of current carrying PUCCH, to indicate above-mentioned one group of N number of PUCCH with ARI One of resource.
The method of the third configuration PUCCH resource is to configure multigroup PUCCH resource, every group of PUCCH resource with high-level signaling Including N number of PUCCH resource.For example, above-mentioned each group of PUCCH resource can be corresponding carrying PUCCH resource a kind of OS numbers or A part of OS numbers of person.ARI indicates one group of PUCCH resource that needs use.Using this method, ARI is actually to carry The information of OS numbers about carrying PUCCH resource.For example, it is assumed that the public DCI dynamic instructions of the structure of a TU, then UE When generating UCI and being handled, there are no the public DCI of TU where receiving PUCCH resource, it is possible to not know this The OS numbers that can be used for PUCCH transmission of TU.Using this method, UE is known that the OS numbers of carrying PUCCH resource by ARI, To start to UCI processing.
The OS numbers that carrying PUCCH resource is obtained by ARI are possible to refer to different from the public DCI of TU where PUCCH resource The information shown.Particularly, ARI can be a range for only indicating the OS numbers for carrying PUCCH resource.UE can basis The OS numbers of ARI instructions are to UCI processing.The OS numbers for being actually available to carrying PUCCH resource can be indicated according to public DCI Information acquisition.UE can transmit PUCCH according to the OS numbers for being actually available to carrying PUCCH resource.Alternatively, ought actually may be used When OS numbers for carrying PUCCH resource are more than or equal to the OS numbers of ARI instructions, UE can only be come according to the OS numbers that ARI is indicated Transmit PUCCH；Otherwise, UE transmits PUCCH according to the OS numbers for being actually available to carrying PUCCH resource.
Can be that PUCCH resource is respectively configured to each PUCCH format when there are multiple PUCCH formats.According to ARI It determines the OS numbers for carrying PUCCH, and further determines that the payload that can be carried of the PUCCH resource of each PUCCH format Bit number is suitble to the PUCCH format of UCI transmission it can also happen that variation.I.e., it is possible to be to determine need according to UCI bit numbers and ARI The PUCCH format to be used.ARI indicates one group of PUCCH resource, and further indicates one in above-mentioned one group of PUCCH PUCCH resource.
In the method for the third configuration PUCCH resource, ARI had not only indicated N number of money in one group of PUCCH resource, but also key group One of source.Alternatively, can also be one group of PUCCH resource for needing to use with a domain instruction in DCI, this domain is actually Carry the information of the OS numbers about carrying PUCCH resource；Be used in combination another and instruction one PUCCH group in N number of resource it One.
