PDCCH占用的物理时间频率资源,以控制信道元素(CCE :control channelelement)为单位进行分配,每个PDCCH含有的CCE数目被称为CCE聚合级别(CCE aggregation level) 。 Occupied by the PDCCH physical time-frequency resource to a control channel element (CCE: control channelelement) allocated as a unit, the number of CCE contained in each PDCCH CCE aggregation level is called (CCE aggregation level). LTE单载波系统中允许的CCE聚合级别等于1, 2, 4, 8。 LTE single carrier system allows a CCE aggregation level is equal to 1, 2, 4, 8. [0003] LTE-Advanced系统要求提供比LTE系统更高的传输速率与小区平均吞吐量。 [0003] LTE-Advanced system requires higher transmission rate than the LTE system and the cell average throughput. 多载波技术(或称为载波聚合技术)已被3GPP确定为满足LTE-Advanced需求的重要技术之一。 Multi-carrier technology (or referred to as carrier aggregation technology) has been identified as one of the important technical 3GPP LTE-Advanced to meet demand. 而多载波技术要求,在下行载波聚合场景下,eNodeB需在多个下行载波上同时为一个LTE-Advanced用户设备(UE)传输数据。 The multi-carrier technology requirements at downlink carrier aggregation scenario, an eNodeB to simultaneously transmit data to a LTE-Advanced user equipment (UE) on the plurality of downlink carriers. 多载波系统中的每个载波可以被称为分支载波,每个分支载波上的物理下行控制信道被称之为分支载波的物理下行控制信道。 A multi-carrier system each carrier may be called the branch carrier, physical downlink control channel on each branch carrier is called physical downlink control channel branch carriers. 如何在多个下行载波上分配下行控制信道资源,尽量避免不同用户不同聚合级别的CCE资源分配碰撞, 是多载波传输需要解决的问题。 How to allocate the downlink control channel resources on multiple downlink carriers to avoid different users different CCE aggregation level resource allocation collision, is a multi-carrier transmission problems to be solved.

[0023] 下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0023] below in conjunction with the present invention in the accompanying drawings, technical solutions of embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention, but not all embodiments example. 基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。 Based on the embodiments of the present invention, all other embodiments of ordinary skill in the art without any creative effort shall fall within the scope of the present invention.

[0024] 若LTE-Advanced系统的PDCCH在M个载波上分散传输,配比因子ni(i = 1,2,..., M)表示每单次排序时从第i个载波上选择的连续CCE数目。 [0024] If the system PDCCH LTE-Advanced dispersed transmission on the M carriers, the ratio factor ni (i = 1,2, ..., M) represents the time per single sort selected from the i-th successive carriers The number of CCE. 排序是指对多个载波的CCE资源进行统一编排。 Sort CCE refers to the resources of multiple carriers unified arrangement. 且,定义4是第i (i = 1,2, . . . , M)个载波上的CCE资源开始排序的起始位置。 And, 4 are defined i (i = 1,2,..., M) of the sort start position CCE resources on the carriers.

[0025] 初始单次排序指的是从各个下行载波的起始CCE位置依照载波顺序选择与各个下行载波的配比因子相同数目的连续CCE资源。 [0025] Initial single sorting means selecting the same number of each downlink carrier ratio factor CCE resources continuously from a starting CCE locations each downlink carrier in accordance with the order of the carriers.

[0026] 对于M个载波上的CCE资源排序,其排序方法是:先进行M个载波的单次排序。 [0026] For the CCE resource ordering M carriers, which sorting method is: first perform a single sort of M carriers. 每单次排序指的是先从第一个载波的第^个CCE开始选择ni个连续的CCE,再从第二个载波的第f2个CCE开始选择n2个连续的CCE,依次顺序,直到从第M个载波的第fM个CCE开始选择nM个连续的CCE。 Per single start ordering means is a carrier of the first CCE start selecting ni ^ th consecutive CCE, and then began to select n2 consecutive CCE's from CCE th second carrier f2, the sequential order, until the fM th of the M-th carrier CCE selection nM consecutive start CCE. 每单次排序完成后,再从第一个载波开始重复上次编排流程,周而复始,直到任意一个下行载波上没有可以按照比例因子选取的CCE资源。 After each single sort is complete, and then repeated from the previous first carrier arrangement process, again and again, until any one of the downlink carrier can be selected not to scale factor CCE resources. [0027] eNodeB100在对M个载波上的CCE资源排序时,需遵循以下规则: [0028]( — )多个载波上的物理下行控制信道在每一个载波上占用的CCE资源必须是连续的,而且这些连续的CCE资源在该载波内的位置及搜索空间完全符合该下行载波要求的控制资源分配方式。 [0027] eNodeB100 When sorting a CCE resources on the M carriers, subject to the following rules: [0028] (-) physical downlink control channel on multiple carriers on each CCE resources occupied by the carrier must be continuous, and these contiguous CCE resource location and the search space of the carrier in the control resource allocation in full compliance with the requirements of downlink carriers.

[0029] ( 二)为了保证上述( 一)项,必须在第n次单次CCE资源排序后,进行第n+1次单次CCE资源排序,每个载波按照自己的配比因子选取CCE资源时,优先选取含有已经排序的CCE资源的分支载波物理下行控制信道内的尚未排序的CCE资源进行第n+1次单次CCE 资源排序;含有已经排序的CCE资源的分支载波物理下行控制信道是指CCE个数最小的有尚未排序的CCE资源的分支载波物理下行控制信道。 [0029] (b) In order to ensure (a) of the above, must be after a single CCE resource ordering the n-th, n + 1 for the first time a single CCE resource ordering, each carrier selected in accordance with their ratio of CCE resources factor when, prefers the CCE resources have not been sorted in the branch carrier comprises physical downlink control channel is CCE resources sorted for the first n + 1 times per CCE resource ordering; physical downlink control channel comprising a branch carrier CCE resources are already sorted refers to the smallest number of CCE CCE resources have not yet been sorted branch carrier physical downlink control channel.

[0030] 多个载波的CCE资源排序在遵循以上规则前提下,可以调整配比因子及排序时M 个载波上的起始排序CCE之间的位置关系,增加系统候选的物理下行控制信道在多个载波上传输的灵活性。 [0030] When sorting a plurality of carriers CCE resources in following the above rules, you can adjust the ratio factor and the positional relationship between the initial sort ordering CCE on the M carriers, increasing the system's physical downlink control channel candidates in a multi- flexibility on a carrier transmission.

[0031] 尽管多个下行载波的配比因子与排序方式是小区特定的,但允许在小区特定条件下的UE特定的载波聚合,允许UE选择系统PDCCH候选集合中的子PDCCH候选集合作为该UE的候选集合。 [0031] Although a plurality of downlink carriers sort ratio factor is a cell-specific, cell-specific, but under conditions allowing the UE-specific carrier aggregation, allowing the sub-set of PDCCH candidates PDCCH candidate UE selection system as a set of the UE the set of candidate.

[0032] 如图1所示,在LTE-Advanced系统中,eNodeBlOO根据UE200的ID从所述的多载波系统中的物理下行控制信道候选集合中选择一个物理下行控制信道,并发射。 [0032] 1, in the LTE-Advanced system, eNodeBlOO select a physical downlink control channel from the control channel according to UE200 ID candidate set of physical downlink according to the multi-carrier system, and transmitted.

[0033] UE200按照控制信息的指示去检测数据信道(假设该UE在该子帧内有数据信 [0033] UE200 accordance with an instruction of the control information to detect the data channel (assuming that the UE has a data channel in the subframe

道)。 Road). 如果数据检测不对,UE就在上行选择一个ACK/NACK信道反馈NACK给eNodeB。 If the data is not detected, UE in selecting an uplink ACK / NACK channel to a NACK eNodeB. 如果 in case

数据检测正确,UE就在上行选择一个ACK/NACK信道反馈ACK给eNodeB。 Detecting the correct data, UE will select an uplink ACK / NACK channel to feed back an ACK eNodeB.

[0034] 本实施例保证了多载波系统中的不同候选物理下行控制信道在各个载波上占用 [0034] The present embodiment ensures a different candidate physical downlink control channel in a multi carrier system on each carrier occupies

的CCE资源或者完全不相交,或者完全相交(即其中的一个PDCCH候选(candidate)在各 The CCE resources or completely disjoint or entirely intersect (i.e., wherein one PDCCH candidate (Candidate) in the

个载波上占用的CCE资源被另一个PDCCH candidate在各个载波上占用的CCE资源完全包含)。 The carriers occupied by another PDCCH candidate CCE resources on respective carriers CCE resources occupied fully contained).

[0035] 如图2所示,是多载波系统中的不同候选物理下行控制信道部分相交的示意图(本图中假设一个编号代表1个CCE资源)。 As shown in FIG. 2 [0035] is different candidate physical downlink control channel portion of the multi-carrier system intersecting a schematic (in this figure is assumed that a CCE number represents a resource). 其中,假如存在某个PDCCH候选c占用了编号为2, 3, 4, 5的CCE (即其起始CCE位置不是该PDCCH候选大小的整数倍处),那么该PDCCH 候选将会与PDCCH候选a (聚合级别为4) , PDCCH候选b (聚合级别为4)部分相交。 Wherein, if there is some c occupied by PDCCH candidate number 2, 3, CCE 4, 5 (i.e., its initial position is not an integral multiple of the CCE of the PDCCH candidates size), then the candidate will be a PDCCH with PDCCH candidate (aggregation level 4), PDCCH candidate B (aggregation level 4) intersecting portion. eNodeB 若分配PDCCH c给某个UE,将导致eNodeB不能分配PDCCH候选a和PDCCH候选b。 If the assigned PDCCH C eNodeB to a UE, eNodeB will not result in dispensing and a PDCCH candidates PDCCH candidate b. 因此, 从降低不同候选物理下行控制信道CCE资源分配碰撞的角度,要避免多载波系统中的不同候选物理下行控制信道部分相交。 Therefore, from the viewpoint of reducing different candidate resource allocation PDCCH CCE collision, to avoid different candidate physical downlink control channel portion of the multi-carrier system intersect.

[0036] 多载波系统中发射ACK/NACK信道的终端,其特征是,检测PDCCH CCE资源,根据互补成对的映射规则获取CCE资源映射的ACK/NACK反馈信道并利用ACK/NACK反馈信道发射ACK/NACK应答信息给基站。 [0036] The multi-carrier system transmitting terminal ACK / NACK channel, wherein the detecting the PDCCH CCE resources, obtaining ACK / NACK feedback channel CCE resource mapping according to a complementary pair of mapping rule and using ACK / NACK feedback channel transmitting ACK / NACK response information to the base station.

[0047] 如图4A所示,本发明实施例的多载波下行控制信道资源分配方法包括以下步骤: eNodeB将M个下行载波上的控制信道元素CCE资源按照各自载波的配比因子及起始排序CCE的位置进行CCE资源排序,每单次CCE资源排序时,从对应的单个下行载波上选取与该载波的配比因子相同数目的连续CCE资源,对M个下行载波CCE资源排序;M个下行多载波上的候选物理下行控制信道在排序后的CCE资源上的起点是该物理下行控制信道的CCE聚合级别的整数倍,并占用与该物理下行控制信道的CCE聚合级别相同数目的连续CCE资源; 所有可能的物理下行控制信道形成了M个下行载波上的物理下行控制信道候选集合(步骤S101);根据用户设备UE的标识信息从所述的物理下行控制信道候选集合中为UE选择一个物理下行控制信道,并发射(步骤S102)。 [0047] FIG. 4A, the multi-carrier downlink control channel resource allocation method of an embodiment of the present invention comprises the steps of: eNodeB the control channel element CCE resources on M downlink carriers according to the composition of the carrier and the start of each factor ordering CCE of CCE resources sorting position, when CCE resources per single sorting, selection and proportioning factor of the carrier the same number of consecutive CCE resources from a single downlink carrier corresponding to the downlink carrier sort M CCE resources; M downlink PDCCH candidates in the CCE resources starting sorted on the multicarrier physical downlink control channel is a CCE aggregation level of an integral multiple, and occupies the PDCCH CCE aggregation level the same number of consecutive CCE resources ; all possible physical downlink control channel candidate set is formed of a physical downlink control channel (step S101) on M downlink carriers; according to the identification information of the user equipment UE from the UE selects a physical control channel candidate set for the physical downlink downlink control channel, and transmitted (step S102).

[0048] 如图4B所示本发明实施例终端侧的多载波系统中接收下行控制信道资源的方法包括:终端根据自己的标识信息,从如实施例一所述方法形成的物理下行控制信道候选集合中选择属于自身的子候选集合,形成该终端的控制信道搜索空间(步骤S201);终端在自身的控制信道搜索空间内盲检测出自己的物理下行控制信道(步骤S202)。 Multicarrier system according to the terminal side of the embodiment [0048] As shown in FIG. 4B of the present invention receives a downlink control channel resources comprising: a terminal in accordance with their identification information, from the physical downlink control channel as the method described in Example candidate formed belonging to the selected set of sub-candidate set itself, forming a control channel search space (step S201) of the terminal; a terminal in its own control channel search space blind detection own physical downlink control channel (step S202). [0049] 终端在单个上行载波上发射ACK/NACK应答信息给对应的基站。 [0049] The terminal transmits uplink carrier on a single ACK / NACK response information to the corresponding base station. 终端具体可以检测PDCCH CCE资源,根据互补成对的映射规则获取CCE资源映射的ACK/NACK反馈信道并利用ACK/NACK反馈信道发射ACK/NACK应答信息给基站。 Specific terminal can detect the PDCCH CCE resources, obtaining ACK / NACK feedback channel according to the CCE resource mapping complementary pair of mapping rule and using ACK / NACK feedback channel for transmitting the ACK / NACK information to the base station. 相应地基站则获取该UE的PDCCH CCE资源所映射的互补成对的ACK/NACK反馈信道,并在该ACK/NACK信道上检测UE的ACK/ NACK应答信息。 Accordingly, the base station acquires the complementary pair PDCCH CCE resources mapped to the UE an ACK / NACK feedback channel, and the UE detects the ACK / NACK information at the ACK / NACK channel.

[0050] 如图6所示,eNodeB对两个下行载波的CCE资源进行排序,其中:M = 2, f2 = ^, & = n2 = 1。 [0050] As shown in FIG 6, eNodeB two CCE resources of downlink carriers sort, where: M = 2, f2 = ^, & = n2 = 1. 各个下行载波的起始排序CCE的索引index相同。 Same sort each downlink carrier starting CCE index index. [0051] CCE资源排序步骤如下: [0051] CCE resource ordering the following steps:

[0052] 如果载波1的起始位置为4,则载波2的起始位置为f2,从载波1上选择CCE资源0进行排序,然后从载波2上选择CCE资源1进行排序,再从载波1上选择CCE资源2进行排序,然后从载波2上选择CCE资源3进行排序。 [0052] If the starting position of the carrier 1 is 4, the start position of the carrier 2 is f2, 0 sort selected from CCE resources on carrier 1, and a carrier selected from the CCE resources sort 21, and then from the carrier 1 2 the choice of CCE resources to sort and select CCE resources from the carrier 23 to be sorted. 每单次排序完成后,再从第一个载波开始重复上次排序流程,周而复始,直到某一个载波的所有CCE资源被全部编排后,整个排序过程完成。 After every single sort is complete, and then repeat from the first carrier last sorting process, again and again, until all the resources of a CCE is a carrier of all the choreography, the entire ordering process is complete.

[0053] 如图8所示,两个下行载波的起始位置可以相同(如图6),但是上行ACK/NACK信道的索引(index)之间可以有偏移(offset)。 [0053] As shown, the starting position of the two downlink carriers may be the same 8 (FIG. 6), but between the uplink ACK / NACK channel index (index) may be offset (offset). 按图6中假设,下行载波1上的编号为0的CCE与下行载波2上编号为1的CCE映射到同一个上行载波相同的ACK/NACK信道,这样2 个CCE只对应了一个ACK/NACK信道。 Assuming in FIG. 6, No. 1 on downlink carrier CCE downlink carrier 2 numbered 0 to CCE 1 are mapped to the same uplink carrier the same ACK / NACK channel, so that two CCE corresponds only one ACK / NACK channel. 为了使这2个CCE对应出2个ACK/NACK信道,将载波2编号为1的CCE对应的上行ACK/NACK信道index加4 (即设offset = 4)。 In order for the two out of two CCE corresponds ACK / NACK channel, the carrier 2 CCE number corresponding to an uplink ACK / NACK channel index plus 4 (i.e., disposed offset = 4). 如图8中偏右向箭头所示,即载波2编号为1的CCE对应的ACK/NACK信道index相当于载波1中编号为8的CCE对应的上行index。 8-right direction indicated by an arrow, i.e., the carrier 2 is a CCE corresponding to a number of ACK / NACK channel index 1 corresponds to the carrier numbered CCE index 8 in a corresponding uplink. 按照此种方法,载波1上的编号为0的CCE与载波2上编号为1的CCE对应出2个上行ACK/NACK反馈信道。 According to this method, the number of carrier 1 and carrier 2 on CCE numbers of CCE 0 1 2 corresponding to the uplink ACK / NACK feedback channel.

[0054] 按照此ACK/NACK反馈规则,对下行载波2以4个连续CCE为一组对CCE index加4(如编号1,3,5,7分别对应上行载波1编号为8, 10, 12, 14对应的ACK/NACK信道),然后下4个连续CCE为一组对CCE index减4 (如图中偏左向箭头所示,编号9, 11, 13, 15分别对应上行载波1编号为0, 2, 4, 6对应的ACK/NACK信道),按照交错顺序进行CCE index与上行ACK/NACK信道映射。 [0054] According to this ACK / NACK feedback rule, downlink carrier 2 to 4 consecutive CCE of CCE index plus a set of 41 numbers (e.g., number of uplink carriers 1,3,5,7 respectively 8, 10, 12 14 corresponding to an ACK / NACK channel), then the next four consecutive CCE of CCE index is a set of minus 4 (to the left as shown in arrows, numbers 9, 11, 13, 15 respectively corresponding to an uplink carrier number 1 0, 2, 4, 6 ACK / NACK channel) corresponding to, for CCE index and the uplink ACK / NACK channel mapping staggered order. 这种方法的本质是互补成对映射。 The essence of this approach is complementary pairs mapping.

[0055] 可以改变ACK/NACK index偏移的offset值,offset值可以取2的整数幂。 [0055] ACK offset value can be changed / NACK index offset, offset values ​​can take integer power of two. 考虑到目前LTE最大的CCE aggregation level是8,offset取4或8时可以提供更多的ACK/ NACK信道。 Given the current LTE is the largest CCE aggregation level 8, offset can take 4 or 8 provide additional ACK / NACK channel.

[0056] 该实施例采用ACK/NACK索引偏移方式,在下行两个载波上行一个载波配置的非对称载波聚合场景下,采用此种互补成对映射方法,可以将互补成对的ACK/NACK信道资源映射对应的相同上行ACK/NACK信道资源索引分配给两个不同上行载波的不同UE,使得上行ACK/NACK反馈信道的利用更为有效。 ACK / NACK [0056] This embodiment employs ACK / NACK index offset manner, in asymmetric carrier aggregation scenario two downlink carriers configured uplink carrier a, the use of such complementary pairs mapping method may be complementary pairs channel resource mapping corresponding to the same uplink ACK / NACK channel resource index is assigned to two different UE different uplink carriers, such that the use of uplink ACK / NACK feedback channel is more effective. [0057] 实施例三 [0057] Example three

[0058] 如图7所示,eNodeB对两个下行载波的CCE资源进行排序,其中:M = 2, f2 = f一l, [0058] As shown, an eNodeB of CCE resources two downlink carriers sort 7, wherein: M = 2, f2 = f L a,

[0059] 该实施例与图6的排序方式的不同之处在于,采用交错互补排序方式。 [0059] This embodiment differs from the ordering of the embodiment of FIG. 6 in that the complementary staggered sort. 采用这样编号方式的优点是使各个载波上的起始CCE位置不同,从而单个上行载波可以为两个下行载波提供多个ACK/NACK反馈信道。 The advantage of using this approach is that the numbering starting CCE different positions on each carrier, so that a single uplink carrier may be provided a plurality of ACK / NACK feedback channel for the two downlink carriers.

[0060] 该实施例采用起始CCE索引偏移方式,在下行两个载波上行一个载波配置的非对称载波聚合场景下,采用此种互补成对映射方法,可以将互补成对的CCE资源映射对应的相同上行ACK/NACK信道资源索引分配给两个不同上行载波的不同UE,使得上行ACK/NACK 反馈信道的利用更为有效。 CCE resources [0060] This embodiment employs a starting CCE index offset manner, asymmetric carrier up two downlink carriers in a carrier aggregation scenario configuration, using complementary pairs of such mapping method, the mapping may be a pair of complementary corresponding to the same uplink ACK / NACK channel resource index is assigned to two different UE different uplink carriers, such that the use of uplink ACK / NACK feedback channel is more effective.

10[0065] (3)对这M/(2'k)个编号序列再按照编号序列间的比例因子进行新的两两编号排序,共产生新的M/(2'(k+l))个编号序列。 10 [0065] (3) these M / (2'k) numbered according to the sequence then the scale factor between the new sequence number pairwise sort numbers, has generated a new M / (2 '(k + l)) numbered sequence. 其中每个编号序列的两个连续的编号被当作一个编号参与两两编号排序; Wherein each of two consecutive numbering sequence are numbered as a numbered ordering participating twenty-two number;

[0066] (4)k增加l,且更新后的k值不大于Kl时,重复(3)过程。 When [0066] (4) k increases l, k and the updated value is not greater than Kl, repeat (3) procedure. 当k大于Kl时,M个载波的CCE资源排序过程结束; When k is greater than Kl, CCE resources of M carriers sorting process ends;

[0067] 特别指出,M个载波的CCE资源排序,采用两两载波聚合的递归排序后的编号序列中的每个编号表示M/2个CCE资源。 [0067] In particular, CCE resources of M carriers sorting using sequence numbers every two carrier aggregation recursive ordering each numbering of M / 2 CCE resources.

[0068] 如图9所示,eNodeB对4个载波进行两两聚合的CCE资源排序,其中配比因子=n2 = n3 = n4 = 1。 [0068] As shown in FIG. 9, eNodeB to four CCE resource ordering carriers twenty-two polymerization, wherein the ratio factor = n2 = n3 = n4 = 1. 载波1和载波2、载波3和载波4都按照图6的方法进行CCE资源逻辑编号。 Carriers 1 and 2, carrier 3 and carrier 4 will be the logical number of CCE resources according to the method of FIG.
