Description

用于在移动通信系统中发送和接收随机化小区间干扰的控制信息的方法和装置 A method and apparatus for transmitting and receiving control information to randomize inter-cell interference in a mobile communication system

技术领域 FIELD

[0001] 本发明一般地涉及移动通信系统,更具体来说涉及用于在下一代多小区移动通信系统中发送和接收随机化由上行链路(UpLink,UL)传输引起的小区间干扰的控制信息的方法和装置。 [0001] The present invention relates generally to control a mobile communication system, and more particularly relates to inter-cell interference randomization for transmitting and receiving in the next generation multi-cell mobile communication system the uplink (UpLink, UL) transmission caused method and device information.

背景技术 Background technique

[0002] 在移动通信技术领域中,近来正交频分多址(Orthogonal FrequencyDivisionMultiple Access, 0FDMA)或单载波频分多址(SingleCarrier-Frequency DivisionMultiple Access, SC-FDMA)已被研究用于无线电信道上的高速传输。 [0002] In the technical field of mobile communication, recently an orthogonal frequency division multiple access (Orthogonal FrequencyDivisionMultiple Access, 0FDMA) or single-carrier frequency division multiple access (SingleCarrier-Frequency DivisionMultiple Access, SC-FDMA) has been investigated for a radio channel high-speed transmission. 异步蜂窝移动通信标准化组织,第三代合作伙伴计划(3rdGeneration Partnership Project, 3GPP)正致力于与多址接入方案有关的下一代移动通信系统的长期演进(Long Term Evolution, LTE)。 Asynchronous cellular mobile communication standardization organization, Third Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) Long Term Evolution is working on next generation mobile communication system with multiple access scheme relating to (Long Term Evolution, LTE).

[0003] 根据数据传输还是非数据传输,LTE系统对于UL控制信息使用不同的传输格式(Transport Format, TP)。 [0003] The data transmission or non-transmission of data, LTE UL control systems for different information using transport format (Transport Format, TP). 当在UL上同时发送数据和控制信息时,数据和控制信息通过时分复用(time Division Multiplexing,TDM)被复用。 When data is transmitted simultaneously on the UL control information and data and control information are multiplexed by time division multiplexing (time Division Multiplexing, TDM). 如果只发送控制信息,则给控制信息分配特定频带。 If only the transmission control information, the control information allocated to a specific frequency band.

[0004] 图1示出在常规的LTE系统中当在UL上只发送控制信息时的传输机制的图。 FIG transport mechanism is shown when the transmission only when the control information on UL [0004] FIG 1 in the conventional LTE system. 水平轴表示时间,而垂直轴表示频率。 The horizontal axis represents time and the vertical axis represents frequency. 在时间上定义了一个子帧102,并且在频率上定义了传输(TX)带宽120。 In time defines a subframe 102, and defines a transmission (TX) 120 in the frequency bandwidth.

[0005] 参考图1,基本的UL时间传输单元即子帧102长为I毫秒,并包括两个时隙104和106,每一个均长0.5毫秒。 [0005] Referring to FIG 1, a basic UL time transmission unit, that is the subframe length I 102 ms, and includes two slots 104 and 106, each of length 0.5 msec. 每一个时隙104或106包括多个长块(Long Block,LB) 108 (或长SC-FDMA码元)和短块(Short Blocks, SB) 110 (或短SC-FDMA码元)。 Each slot 104 or 106 includes a plurality of long blocks (Long Block, LB) 108 (or long SC-FDMA symbols) and a short block (Short Blocks, SB) 110 (or short SC-FDMA symbols). 在图1所示情况中,一个时隙被配置成具有六个LB 108和两个SB 110。 In the case shown in FIG 1, one slot is configured to have two six LB 108 and SB 110.

[0006] 最小的频率传输单元是LB的频音(frequency tone),并且基本的资源分配单元是资源单元(Resource Unit,RU)。 [0006] The minimum frequency transmission unit is LB pilot tone (frequency tone), and a basic resource allocation unit is a Resource Unit (Resource Unit, RU). RU 112和RU 114均具有多个频音,这里,例如12个频音形成一个RU。 RU 112 and RU 114 has a plurality of tones, where, for example, 12 frequency tones form one RU. 通过利用分散的频音而非连续的频音形成RU,也可以实现频率分集(frequency diversity)。 By using scattered pilot tones are formed rather than a continuous pilot tone RU, can achieve frequency diversity (frequency diversity).

[0007] 由于LB 108和SB 110具有相同的采样率(sampling rate),所以SB 110具有的频音大小是LB 108的频音大小的两倍。 [0007] Since the LB 108 and SB 110 has the same sampling rate (sampling rate), so that SB 110 having a pilot tone frequency tone size is twice the size of the LB 108. 在SB 110中分配给一个RU的频音的数量是在LB108中分配给一个RU的频音数量的一半。 RU assigned to a number of tones in SB 110 is assigned to a half of the number of tones in RU LB108. 在图1所示的情况中,LB 108携带控制信息,而SB 108携带导频信号(或参考信号(Reference Signal, RS))。 In the case shown in FIG. 1, LB 108 carry control information, and the SB 108 carries a pilot signal (or reference signal (Reference Signal, RS)). 导频信号是预先确定的序列,接收器利用所述序列执行信道估计,以进行相干解调。 Sequence of pilot signals are determined in advance, the receiver utilizes channel estimation sequence execution, to perform coherent demodulation.

[0008] 如果在UL上只发送控制信息,则在LTE系统中该控制信息在预先确定的频带中发送。 [0008] If only control information is transmitted on the UL, the LTE system in the control information transmitted in a predetermined frequency band. 在图1中,所述频带是位于TX带宽120的两侧的RU 112和RU 114中的至少一个。 In Figure 1, the bandwidth of the frequency band is located on both sides of the TX 120 RU 112 and an RU 114 at least.

[0009] 一般来说,携带控制信息的频带以RU为单元来定义。 [0009] In general, the band carrying control information is defined in units of RU. 当要求多个RU时,使用连续的RU以满足单载波特性。 When asked plurality RU, RU to meet using a continuous single carrier property. 为了增加用于一个子帧的频率分集,这里可以以时隙为基础发生跳频。 In order to increase frequency diversity for one subframe, there may be slot-based frequency hopping occurs.

[0010] 在图1中,第一控制信息(控制#1)在第一时隙104中在RU 112中发送,并且通过跳频在第二时隙106中在RU 114中发送。 [0010], the first control information (Control # 1) in FIG. 1 transmission in the first slot 104 in the RU 112, and 106 transmitted in RU 114 in second slot by frequency hopping. 同时,第二控制信息(控制#2)在第一时隙104中在RU 114中发送,并且通过跳频在第二时隙106中在RU 112中发送。 Meanwhile, the second control information (Control # 2) 114 is transmitted in the first slot 104 in the RU, and 106 transmitted in RU 112 in second slot by frequency hopping.

[0011] 控制信息是例如指示成功或失败的下行链路(DownLink,DL)数据接收的反馈信息,即肯定应答/ 否定应答(ACKnowledgment/NagativeACKnowledgment, ACK/NACK),它一般是I比特。 [0011] the control information is information indicating success or failure, for example, downlink (DownLink, DL) data received feedback information, i.e., an acknowledgment / negative acknowledgment (ACKnowledgment / NagativeACKnowledgment, ACK / NACK), it is generally I bits. 其在多个LB中重复,以便提高接收性能,并扩展小区覆盖范围。 Repeated in a plurality of LB in order to increase reception performance and expand cell coverage. 当从不同的用户发送I比特的控制信息时,可以考虑把码分复用(Code Division Multiplexing,CDM)用于复用该I比特控制信息。 When the I-bit control information is transmitted from different users, consider the code division multiplexing (Code Division Multiplexing, CDM) for multiplexing the I-bit control information. 和频分复用(Frequency Division Multiplexing, FDM)相t匕,CDM的特性是抗干扰的鲁棒性。 And frequency division multiplexing (Frequency Division Multiplexing, FDM) with t dagger, the CDM characteristics of interference robustness.

[0012] 作为用于控制信息的CDM复用的码序列来讨论Zadoff-ChU (ZC)序列。 [0012] As the code sequence for CDM multiplexing control information to discuss Zadoff-ChU (ZC) sequence. ZC序列因其在时间和频率上的恒定包络而提供了良好的峰值平均功率比(Peak-to-Average PowerRatio, PAPR)特性和在频率上优秀的信道估计性能。 ZC sequence in the time and frequency of its constant envelope but provides good PAPR (Peak-to-Average PowerRatio, PAPR) characteristics and excellent channel estimation in frequency performance. 对于UL传输,PAPR是最重要的考虑。 For UL transmission, PAPR is the most important consideration. 较高的PAPR导致较小的小区覆盖范围,因而增大了对用户设备(User Equipment,UE)的信号功率要求。 Higher PAPR leads to a smaller cell coverage, thereby increasing a signal power requirement for a user equipment (User Equipment, UE) of. 因此,首先应该致力于在UL传输中降低PAPR。 So, first of all should aim to reduce PAPR in UL transmission.

[0013] 具有良好的PAPR特性的ZC序列对于非零移位(non-zero shift)具有为零的循环自相关值。 [0013] with good PAPR characteristics of the ZC sequence has zero circular autocorrelation for a non-zero shift values ​​(non-zero shift). 下面的等式(I)在数学上描述了ZC序列。 The following equation (I) described in the ZC sequence mathematically.

[0014] [0014]

Figure CN101627560BD00051

[0015] 其中,N表示ZC序列的长度,P表示ZC序列的索引,并且η表示ZC序列的采样的索引(η = 0,...,Ν-1)。 [0015] where, N represents the ZC sequence length, P denotes the index of the ZC sequence, and [eta] represents a sampling ZC sequence index (η = 0, ..., Ν-1). 因为P和N应该互质,所以序列索引P的数量随着序列长度N变化。 Because P and N should be relatively prime, the number of sequence indices as the sequence length N P changes. 因此,对于N = 6,P = 1,5,产生两个ZC序列。 Thus, for N = 6, P = 1,5, two ZC sequences generated. 如果N是质数,则产生N-1个序列。 If N is a prime number, N-1 is generated sequences.

[0016] 由等式⑴产生的两个具有不同P值的ZC序列具有复数互相关,其绝对值是I/7^,相位随着P变化。 [0016] two ZC sequences having different P values ​​generated by Equation ⑴ having a plurality of cross-correlation, which is an absolute value of I / 7 ^, with the phase P changes.

[0017] 通过ZC序列把来自一个用户的控制信息与来自其他用户的控制信息区分,这将通过举例来更详细地描述。 [0017] The ZC sequence by the control information from a user and control information to distinguish from other users, which will be described in more detail by way of example.

[0018] 在同一小区内,来自不同UE的I比特控制信息由ZC序列的时域循环移位值(cyclic shift value)标识。 [0018] in the same cell, I bits from different UE's control information field by a ZC sequence cyclic shift values ​​(cyclic shift value) identifier. 循环移位值是特定于UE的,以满足其大于无线电传输路径的最大传输延迟的条件,从而确保UE间的相互正交。 Cyclic shift values ​​are UE-specific to satisfy the condition that is greater than the maximum transmission delay of the radio transmission path, thus ensuring mutual orthogonality among the UE. 因此,对于多址接入可容纳的UE的数量依赖于ZC序列的长度和循环移位值。 Thus, for multiple access UE can be accommodated depends on the length and the number of cyclic shift value of a ZC sequence. 例如,如果ZC序列长为12个采样,并且确保ZC序列之间的正交性的最小循环移位值是2个采样,则六个UE(= 12/2)可获得多址接入。 For example, if the ZC sequence length of 12 samples, and to ensure orthogonality between the minimum cyclic shift value of a ZC sequence is 2 samples, six of the UE (= 12/2) obtained multiple access.

[0019] 图2示出了来自UE的控制信息被CDM复用的传输机制。 [0019] FIG. 2 shows a transmission mechanism for control information from the UE are CDM-multiplexed.

[0020] 参考图2,在小区202 (小区A)中,第一和第二UE 204和206 (UE#1和UE#2)在LB中使用相同的ZC序列,即ZC#1,并且为了用户识别分别将ZC#1循环移位0208和Λ 210。 [0020] Referring to FIG 2, in cell 202 (cell A), the first and second UE 204 and 206 (UE # 1 and UE # 2) use the same ZC sequence in LB, i.e. ZC # 1, and for user identification, respectively a cyclic shift ZC # 1 0208 and Λ 210. 在图2所示的情况中,为了扩展小区覆盖范围,UE#1和UE#2均通过把预期(intended)的I比特UL控制信息的调制码元重复六次,即在六个LB中重复该调制码元,并且在每一个LB中把重复的码元和经过循环移位的ZC序列即ZC#1相乘来产生控制信道信号。 In the case shown in FIG. 2, to expand cell coverage, UE # 1 and UE # 2 are contemplated by the modulation code (Intended) I-bit UL control information six membered repeated, i.e., repeated in six LB the modulation symbols, and in each LB, and the repetition symbols, cyclic shifted ZC sequence is multiplied i.e. ZC # 1 generates a control channel signal. 由于ZC序列的循环自相关特性,这些控制信道信号在UEtn和UE#2之间保持正交而没有干扰。 Since the ZC sequence cyclic autocorrelation characteristics, these control channels to maintain orthogonality between the signals and the UE # 2 UEtn without interference. Λ 210被设置为大于无线电传输路径的最大传输延迟。 Λ 210 is set to be larger than the maximum transmission delay of the radio transmission path. 每一个时隙中的两个SB携带用于控制信息的相干解调的导频。 Each slot carries SB for controlling the two coherent demodulation of the pilot information. 为了说明的目的,图2中只示出了控制信息的一个时隙。 For purposes of illustration, FIG. 2 shows only one slot control information.

[0021] 在小区220 (小区B)中,第三和第四UE 222和224 (UE#3和UE#4)在LB中使用相同的ZC序列即ZC#2,并且为了用户识别分别将ZC#2循环移位0226和Λ 228。 [0021] In the cell 220 (cell B), the third and fourth UE 222 and 224 (UE # 3 and UE # 4) use the same ZC sequence in LB i.e. ZC # 2, respectively, and to identify the user ZC 0226 # 2 cyclic shift and Λ 228. 由于ZC序列的循环自相关特性,来自UE#3和UE#4的控制信道信号在它们之间保持正交而没有干扰。 Since the cyclic autocorrelation characteristic of the ZC sequence, control channel signals from UE # 3 and UE #. 4 is kept orthogonal without interference between them.

[0022] 但是,当来自不同小区的UE的控制信道信号使用不同的ZC序列时,这个控制信息传输方案引起这些小区之间的干扰。 [0022] However, when the control channel signals using different ZC sequences of different cells from the UE, the information transmission control program causing interference between these cells. 在图2中,小区A的UE#1和UE#2使用不同于小区B的UE#3和UE#4的ZC序列。 In Figure 2, cell A UE # 1 UE # 2 and UE # ZC sequence differs from the use of B cells in the 3 and UE # 4. ZC序列的互相关特性导致UE间的与ZC序列之间的互相关成比例的干扰。 Cross-correlation characteristic of ZC sequences cause interference proportional to the cross-correlation between the ZC sequences between the UE. 因此,需要一种用于降低由如上所述的控制信息传输引起的小区间干扰的方法。 Therefore, a method of inter-cell caused by control information transmission as described above for reducing interference.

[0048] 对于CDM,使用了ZC序列,尽管任何其他具有类似特性的码序列也可供使用。 [0048] For the CDM, a ZC sequence is used, although any other code sequence with similar characteristics are also available. 控制信息是I比特控制信息,例如这里的ACK/NACK。 I bits of the control information is control information, for example where ACK / NACK. 但是,本发明的小区间干扰减小方法也适用于具有多个比特的控制信息,例如信道质量指示符(Channel Quality Indicator,CQI)。 However, inter-cell interference reduction method of the present invention is also applicable to the control information having a plurality of bits, such as channel quality indicator (Channel Quality Indicator, CQI). 在这种情况下,控制信息的每一个比特被在一个SC-FDMA码元中发送。 In this case, each bit of control information being sent in one SC-FDMA symbol. 所述小区间干扰减小方法也适用于不同类型的控制信息的CDM传输,不同类型的控制信息例如I比特控制信息和具有多个比特的控制信息。 The inter-cell interference reduction method is also applicable to different types of CDM transmission of control information, different types of control information such as the I-bit control information and control information having a plurality of bits.

[0049] 当相邻小区中的UE在M个SC-FDMA码元即M个作为UL时间传输单元的LB中使用长度为N的不同ZC序列发送它们的控制信息时,发生小区间干扰。 [0049] When the UE in neighboring cells transmit their control information using the length of the M SC-FDMA symbols M of LB as UL time transmission units for different ZC sequences of N, inter-cell interference. [0050] 如果来自相邻小区内的UE的LB中的序列之间的相关的相位被随机化,同时保持ZC序列的循环自相关和互相关特性,则在接收器处相邻小区间干扰的相位在携带子帧的控制信息的LB的累积期间被跨LB随机化,从而降低了平均干扰功率。 [0050] If the relative phase between the UE LB in sequence from the adjacent cell is randomized, while maintaining a ZC sequence cyclic autocorrelation and cross-correlation properties, the interference between neighboring cells at the receiver LB are bridged during the phase accumulation LB carry control information subframe randomized, thus reducing the average interference power.

[0051] 根据本发明的实施例,每一个UE以子帧中的LB为基础产生其ZC序列,并把具有随机相位或者随机循环移位值的随机序列施加于每一个LB中的ZC序列,从而随机化该ZC序列。 [0051] According to an embodiment of the present invention, each UE in a subframe basis LB generates its ZC sequence, and the random sequence having a random phase or a random cyclic shift values ​​applied to the ZC sequence in each LB, thereby randomizing the ZC sequence. 然后,UE利用被随机化的ZC序列发送控制信息。 Then, UE using the randomized ZC sequence to transmit control information. 随机序列是特定于小区的。 Random sequence is cell-specific. 针对每一个UE使用相位值或循环移位值的不同随机序列进一步提高干扰随机化。 Different random sequence for each UE using the phase values ​​or cyclic shift values ​​of interference randomization is further increased.

[0052] 本发明的实施例提出了三种方法。 Example [0052] The present invention proposes three ways. 在下面的描述中,长度为N的ZC序列由gp (η)表示。 In the following description, a ZC sequence of length N is represented by gp (η). ZC序列gp (η)被在M个LB上随机化,并且控制信息和随机化(randomized) ZC序列g/ p,ffl,k(n)相乘,其中,k表示携带控制信息的信道的索引。 ZC sequence gp (η) is randomized over M an LB, and the control information, and randomized (randomized) ZC sequence g / p, ffl, k (n) is multiplied by, where, k represents a channel carrying control information index .

[0053] 等式⑵描述了根据方法I的随机化ZC序列。 [0053] The method described in Equation I ⑵ randomized ZC sequence.

[0054] g' p,m,k(n) = gp((n+dk)mod N).SMjI11, [0054] g 'p, m, k (n) = gp ((n + dk) mod N) .SMjI11,

[0056] 其中,dk表示相同ZC序列的循环移位值,通过dk标识携带控制信息的信道k。 [0056] wherein, dk denotes a cyclic shift value of the same ZC sequence, channel k carrying the control information through a dk identification. 循环移位值最好是时域循环移位值,尽管其可以是频域循环移位值。 Cyclic shift value is preferably a time domain cyclic shift value, although it may be frequency domain cyclic shift value. 在等式(2)中,mod代表模运算。 In Equation (2), mod representative of a modulo operation. 例如,A mod B代表A除以B的余数。 For example, A mod B represents A divided by B's.

[0057] SM, m表示长度为M的正交码,是+Is或-1s。 [0057] SM, m represents the orthogonal code of length M, is + Is or -1s. 这个正交码可以是沃尔什码。 The orthogonal codes can be Walsh codes. m表示控制信息被映射到的LB的索引。 m represents an LB index information is mapped to control. 如果控制信息在子帧的时隙中被重复四次,则将长度为4的沃尔什序列的码片与每一个时隙的LB逐一相乘,并且子帧中的两个时隙的沃尔什序列的组合对于每个小区是不同的,因此把小区间干扰随机化。 If the control information is repeated four times in the slot of the subframe, then the length of a Walsh chip sequence is multiplied by one of 4, and LB for each time slot, and the sub-frame two slots fertile combination of Walsh sequences for each cell are different, and therefore the inter-cell interference randomization. 为了另外的随机化,沃尔什序列的不同组合可以被用于每一个UE。 For additional randomization, a different combination of Walsh sequences can be used for each UE.

[0058] 等式(3)描述了根据方法2的随机化ZC序列。 [0058] Equation (3) describes the randomized ZC sequence according to Method 2.

[_] SP,m,k W = Sp (O + dk) mod N).ej<L, [_] SP, m, k W = Sp (O + dk) mod N) .ej <L,

[0060] (m = I, 2,..., Μ, η = 0,1, 2..., Ν_1).....(3) [0060] (m = I, 2, ..., Μ, η = 0,1, 2 ..., Ν_1) ..... (3)

[0061] 其中,Φπ表示在每一个LB中改变ZC序列gp(n)的相位的随机相位值。 [0061] wherein, Φπ random phase value of the phase change represents the ZC sequence gp (n) in each of the LB. 通过在子帧的LB中对于相邻小区使用不同的随机相位值的集合,即不同的随机相位序列{ Φπ},小区间干扰被随机化。 By using different sets of random phase values ​​to adjacent cells in LB subframe, i.e. different random phase sequences {Φπ}, the inter-cell interference is randomized.

[0062] 等式(4)描述了根据方法3的随机化ZC序列。 [0062] Equation (4) describes the randomized ZC sequence according to Method 3.

[0063] g' p,m,k(n) = gp((n+dk+Am)mod N), [0063] g 'p, m, k (n) = gp ((n + dk + Am) mod N),

[0064] (m = I, 2,.., Μ, η = O, I, 2.., Ν_1).....(4) [0064] (m = I, 2, .., Μ, η = O, I, 2 .., Ν_1) ..... (4)

[0065] 其中,Λ m表示在每一个LB中改变ZC序列gp (η)的时域循环移位值dk的随机循环移位值。 [0065] wherein, Λ m represents randomly changing the cyclic shift value of the ZC sequence gp (η) domain cyclic shift value dk of each of LB. 通过在子帧的LB中对于相邻小区使用不同的随机时域循环移位值的集合,即不同的随机时域循环移位序列{Λπ},小区间干扰被随机化。 By using different sets of time domain cyclic shift values ​​to adjacent cells in LB random sub-frame, i.e. different random time-domain cyclic shift sequences {Λπ}, the inter-cell interference is randomized. 虽然这里随机循环移位值被用在时域中,但是它们可以被适配为用在频域中。 Although the random cyclic shift values ​​are used in the field, they may be adapted to be used in the frequency domain.

[0066] 图3是示出根据本发明的实施例的使用随机化ZC序列发送控制信息的操作的流程图。 [0066] FIG. 3 is a flowchart illustrating operation of transmitting control information according to an embodiment of the present invention using the randomized ZC sequence.

[0067] 参考图3,UE在步骤302中通过信令从节点B接收序列信息和随机序列信息。 [0067] Referring to FIG 3, UE receives sequence information and random sequence information from a Node B by signaling in step 302. 序列信息是关于用于在发送控制信息时使用的ZC序列,包括ZC序列的索引和循环移位值。 Sequence information is about a ZC sequence for use in transmitting control information, including the index and the cyclic shift values ​​of ZC sequence. 随机序列信息被用于对ZC序列进行随机化,包括作为随机相位值集合的随机相位序列或作为随机时域循环移位值集合的随机时域循环移位序列,以供应用于子帧的LB。 Random sequence information is used for randomizing the ZC sequence, including a random phase sequence as a set of random phase values ​​or a random time-domain cyclic shift as a sequence of random domain cyclic shift value is set to supply a subframe for LB . 所述信令是上层(例如L2)信令或者物理层(LI)信令。 The signaling is upper-layer (e.g. L2) signaling or physical layer (LI) signaling. 为了随机化小区间干扰,随机相位序列或者随机时域循环移位序列对于每一个小区是不同的。 To randomize inter-cell interference, the random phase sequence or the random time-domain cyclic shift sequence is different for each of the cells. 为了进一步的干扰随机化,随机相位序列或者随机时域循环移位序列也可以被设置为对于每一个UE是不同的。 For further interference randomization, the random phase sequence or the random time-domain cyclic shift sequence can also be set for each UE is different.

[0068] 在步骤304中,UE产生控制信息,并使用该控制信息产生复数值调制码元(此后称为控制码元)。 [0068] In step 304, UE generates the control information, and using the control information generating complex-valued modulation symbols (hereinafter referred to as control symbols). 控制码元的数量等于被分配用于传输控制信息的LB的数量。 The number of control symbols is allocated equal number of LB for transmission of control information. 例如,如果控制信息是I比特,则UE通过重复生成和所分配的LB的数量一样多的控制码元。 For example, if the control information is an I-bit, generated by repeating the UE and number of assigned LB as many control symbols.

[0069] 在步骤306中,UE使用序列信息中包括的索引和循环移位值产生ZC序列。 [0069] In step 306, UE using the sequence information included in the index and to generate a ZC sequence cyclic shift value. 然后,在步骤308中,UE根据随机序列信息中包括的随机相位序列或者随机时域循环移位序列产生随机值。 Then, in step 308, UE random phase sequence according to the information included in a random sequence or a random time-domain cyclic shift sequence generated random values. 随机值是沃尔什序列、随机相位值或随机时域循环移位值。 Random values ​​are a Walsh sequence, random phase values, or random time-domain cyclic shift values. 这些随机值对于每一个小区和/或每一个UE是不同的。 These random values ​​for each cell and / or each UE is different. 在步骤310中,UE通过以LB为基础对ZC序列施加随机值来产生随机化ZC序列。 In step 310, UE LB by applying random values ​​based on the randomized ZC sequence to generate a ZC sequence. 在步骤312中,UE把随机化ZC序列和控制码元相乘,把乘积映射到LB,并发送经映射的LB。 In step 312, UE randomized ZC sequence and the control symbols are multiplied, the product is mapped to an LB, and transmits the mapped LB.

[0070] 图4是示出根据本发明的实施例的用于在节点B中接收控制信息的操作的流程图。 [0070] FIG. 4 is a diagram showing an embodiment of the present invention, a flow chart of operation of the information received in the Node B control.

[0071] 参考图4,在步骤402中,节点B通过在多个LB中把从预期UE接收到的信号与施加于该信号的ZC序列相关获取相关信号。 [0071] Referring to FIG 4, in step 402, the Node B by the UE in the plurality LB from the expected received signal with the signal applied to the ZC sequence acquired correlation signal correlation. 在步骤404中,节点B对从UE接收到的导频信号执行信道估计,并利用信道估计对所述相关信号执行信道补偿。 In step 404, the Node B leads to a pilot signal received from the UE performs channel estimation, and channel estimation performs channel compensation for the correlation signal. 在步骤406中,节点B通过以LB为基础把对应于UE的随机值施加于经过信道补偿的相关信号,从而从经过信道补偿的相关信号去除随机值来获取控制信息。 In step 406, the Node B by LB corresponding to the UE based on the random value applied to the correlation signal after channel compensation, thereby removing random values ​​from the channel-compensated correlation signal to obtain control information. 对应于UE的随机值是从节点B发送到UE的随机序列信息得知的。 Random values ​​corresponding to the UE is transmitted from node B to random sequence information that the UE.

[0072] 在上面的控制信息的发送和接收中,LB (即SC-FDMA码元)是基本单位,控制信息被映射到该基本单位,以进行传输。 [0072] In the transmitting and receiving control information in the above, an LB (i.e. SC-FDMA symbol) is a basic unit, control information is mapped to the basic unit for transmission. 以LB为单位重复ZC序列,并且随机相位序列或随机时域循环移位序列的元素逐LB地变化。 LB repeat units in the ZC sequence, and the random phase sequence or the random time-domain element of a cyclic shift sequence change LB by.

[0073] 在多个小区存在于同一节点B下的情况中,每一个小区中的UE使用相同的ZC序列和不同的时域循环移位值复用它们的控制信道。 [0073] In the case where a plurality of cells exist under the same Node B, a UE in each cell using the same ZC sequence and different time domain cyclic shift value of a control channel multiplexed thereof. 如果在节点B的小区中以LB为基础使用不同的随机相位序列或者随机时域循环移位序列,则在UE间可能会失去正交性。 If the node B cells to LB basis using a different random phase sequences or random time-domain cyclic shift sequence is between the UE may lose orthogonality. 因此,在这种环境下,随机相位序列或者随机时域循环移位序列是特定于节点B的,并且节点B的小区使用相同的随机序列。 Accordingly, in this environment, the random phase sequence or the random time-domain cyclic shift sequence is specific to the Node B, the Node B and the cell using the same random sequence.

[0074] 本发明的第一实施例实施了等式(2)中描述的方法I。 [0074] The first embodiment of the present invention a method of equation (2) described in I.

[0075] 图5示出了根据本发明的第一实施例的控制信息的传输机制。 [0075] FIG. 5 shows a transmission mechanism for control information according to the first embodiment of the present invention.

[0076] 参考图5,在一个子帧中,相同的I比特控制信息出现8次,并以时隙为基础经受跳频,以便实现频率分集。 [0076] Referring to Figure 5, in one subframe, the same I-bit control information occurs 8 times, and subjected to slot-based frequency hopping, in order to achieve frequency diversity. 如果在每一个时隙中,两个SB以及第一和最后的LB携带用于信道估计的导频,则该时隙剩余的LB可被用于发送控制信息。 If each slot, and the first two and last SB LB carries a pilot channel estimation, the time slot may be remaining LB for transmitting control information. 虽然这里一个RU被用于发送控制信息,但是可以使用多个RU来支持多个用户。 Although one RU is used for transmitting control information, a plurality of RU may be used to support multiple users.

[0077] 在第一时隙中,携带I比特控制信息的调制码元出现4次,以供在四个LB中传输,并且以LB为基础乘以长度为4的正交码S1502( = Sl4aSl4j2Sl4j3Sl4j4)。 [0077] in the first slot, carrying the I-bit control information modulation symbol occurs four times, for transmission in four LB, LB-based and are multiplied by orthogonal codes of length 4 in S1502 (= Sl4aSl4j2Sl4j3Sl4j4 ). Sl4, x代表正交码SI的码片X。 Sl4, x orthogonal code representatives SI chip X. 导频序列也以LB或SB为基础乘以长度为4的正交码SI' 504( = S1' 4,iSl' 4,2S1' 4,3S1' 4,4)。 The pilot sequence is also based in LB or SB times the length of an orthogonal code SI 4 of '504 (= S1' 4, iSl '4,2S1' 4,3S1 '4,4). 使用正交码能够增加多址接入(multiple-access)用户的数量。 Using orthogonal codes can increase the number of multiple-access (multiple-access) users. 例如,对于长度4,有四个正交码可用。 For example, for length 4, four orthogonal codes are available. 使用四个正交码能够使在相同的时频资源中容纳的用户数量是不使用正交码时的四倍。 Four orthogonal codes using the number of users can be accommodated in the same frequency resource is not used when the orthogonal codes four times.

[0078] 在第二时隙中,I比特控制信息出现四次,并且以LB为基础乘以长度为4的正交码S2 506 ( = S24j1S24j2S24j3S24j4)。 [0078] in the second slot, the I-bit control information occur four times, and at times the length LB based orthogonal codes 4 S2 506 (= S24j1S24j2S24j3S24j4). 导频序列也以LB或SB为基础乘以长度为4的正交码S2' 508( = S2' 4j1S2/ 4j2S2/ 4j3S2/ 4,4)。 Pilot sequence also LB or SB basis multiplied by an orthogonal code of length 4 S2 '508 (= S2' 4j1S2 / 4j2S2 / 4j3S2 / 4,4).

[0079] 节点B向UE发信号通知正交码S1502、S1' 504、S2506和S2' 508。 [0079] Node B notifies orthogonal code S1502, S1 '504, S2506, and S2' 508 to the UE signals. 由于正交码的性质所致,其长度应该是4的倍数。 Due to the nature of orthogonal codes due to its length should be a multiple of four. 在图5中,长度为4的正交码被施加于每一个时隙。 In FIG. 5, orthogonal codes of length 4 are applied to each slot. 如果在图5的传输机制中,跳频不以时隙为基础发生,则可以认为控制信息在一个子帧传输期间经历了频率上小到可忽略的信道变化。 If the transport mechanism of FIG. 5, the slot-based frequency hopping is not to occur, it may be considered control information during one sub-frame transmission has undergone channel variation across frequency negligibly small. 因此,即使正交码的长度被扩展到一个子帧,也仍保持正交性。 Therefore, even if the length of the orthogonal codes is extended to one subframe, and still maintain orthogonality. 在这种情况下,长度为8的正交码可被用于在一个子帧中发送控制信息。 In this case, orthogonal codes of length 8 can be used to transmit control information in one subframe.

[0080] 针对每一个小区设置要施加于一个子帧的时隙的正交码的不同组合,以便随机化小区间干扰。 [0080] The different combinations for each cell arranged to be applied to the slots of one subframe orthogonal code, in order to randomize inter-cell interference. 例如,为了在时隙中发送控制信息,小区A顺序地使用正交码{SI,S2},并且小区B顺序地使用正交码{S3,S4}。 For example, in order to transmit control information in a slot, the cell A uses orthogonal code sequence {SI, S2}, and B cells sequentially using orthogonal codes {S3, S4}. 正交码组合{S3,S4}包括至少一个不同于正交码组合{SI,S2}的正交码。 Orthogonal code combination {S3, S4} includes at least one is different from the orthogonal code combination {SI, S2} orthogonal codes.

[0085] 当只发送控制信息而无数据时,正交码生成器626根据从控制器610接收到的关于要被用于时隙的特定于小区或特定于UE的正交码的信息产生用于LB/SB的正交码,并根据从控制器610接收到的定时信息把正交码的码片施加于映射到LB的控制信道信号的控制码元。 [0085] When only control information is transmitted without data, orthogonal code generator 626 generates orthogonal codes with the information received from the controller 610 to be used on a particular time slot in a cell-specific or UE- orthogonal code to LB / SB, and based on information received from the timing controller 610 to the orthogonal code chip is applied to the symbols mapped to the control channel of signal LB. 正交码信息通过节点B信令提供给控制器610。 Orthogonal code information is provided to controller 610 by Node B signaling.

[0131] 共轭器1146计算ZC序列的共轭结果(consequence)。 [0131] conjugator 1146 calculates the conjugate results ZC sequence (consequence). 乘法器1148通过以LB为基础把控制信道信号和共轭序列相乘来对从DEMUX 1124接收到的控制信道信号进行CDM解复用。 The multiplier 1148 received from DEMUX 1124 by the channel to the CDM signal LB based solution to the control channel signal and a conjugated sequence multiplied multiplexed. 累积器1150针对ZC序列的长度累积乘积信号。 1150 Cumulative Cumulative product signal for the length of the ZC sequence. 相关器1140的乘法器1148可以被相位旋转器代替,所述相位旋转器根据从序列生成器1144接收到的序列的相位值dk以LB为基础改变控制信道信号的相位。 1148 correlator multiplier 1140 may be replaced by a phase rotator, the phase rotator according to the phase values ​​dk of the sequence received from sequence generator 1144 to the phase LB basis to change the control channel signal. 信道补偿器1152利用从信道估计器1130接收到的信道估计对累积信号进行信道补偿。 1152 using the channel compensator 1130 received from the channel estimator to estimate channel signal accumulation channel compensation.

[0132] 在去随机化器1142中,随机值生成器1156根据随机序列信息计算UE发送控制信息时使用的随机相位值的共轭相位值。 [0132] In derandomizer 1142, a random value generator 1156 calculates the UE transmits a random sequence information conjugate random phase values ​​used for phase control value in accordance with the information. 乘法器1158以LB为基础把经过信道补偿的信号和所述共轭相位值相乘。 LB basis in the multiplier 1158 through the channel compensation signal and said phase conjugate of the value. 像发送器的乘法器1046那样,去随机化器1142的乘法器1158可以被相位旋转器代替,所述相位旋转器根据从序列生成器1156接收到的随机序列的相位值Φπ或Am以LB为基础改变控制信道信号的相位。 Like multiplier 1046 as the transmitter, multiplier 1142 of derandomizer 1158 can be replaced by a phase rotator, according to the phase rotator or phase values ​​Am Φπ random sequence received from sequence generator 1156 to LB is in changing the phase of the signal channel basis.

[0133] 累积器1160针对I比特信息被重复地映射到的LB的数量累积从乘法器1158接收到的信号,从而获取I比特控制信息。 [0133] accumulator accumulated signal received from the multiplier 1160 to 1158 for the number of I LB bit information is repeatedly mapped, thereby acquiring I-bit control information. 随机序列信息被从节点B发信号通知给UE,以使节点B和UE都知晓随机序列信息。 Random sequence information is signaled from the Node B to the UE, so that the Node B and the UE are aware of the random sequence information.

[0134] 在本发明的修改的实施例中,信道补偿器1152被置于乘法器1158和累积器1160之间。 [0134] In a modified embodiment of the present invention, channel compensator 1152 is disposed between multiplier 1158 and accumulator 1160. 虽然在图1lB中相关器1140和去随机化器1142被分开地配置,但是依赖于配置方法,相关器1140的序列生成器1144和去随机化器1142的随机值生成器1156可以被合并在单个设备中。 Although 1142 is arranged separately in FIG 1lB correlators 1140 and derandomizer, but depending on the configuration method of the correlator sequence generator 1140 1144 and derandomizer 1142 random value generator 1156 may be combined in a single device. 例如,如果相关器1140被配置成使得序列生成器1144为每一个UE生成被施加了随机序列的ZC序列,则去随机化器1142的乘法器1158和随机值生成器1156不被使用。 For example, if correlator 1140 is configured so that sequence generator 1144 for each UE generates the ZC sequence applied to a random sequence, the derandomizer 1142 multiplier 1158 and random value generator 1156 is not used. 因此,实现了等同于图1lB中所示的设备。 Accordingly, achieved is equivalent to the apparatus shown in FIG 1lB. 在这种情况下,像发送器中的乘法器那样,相关器1140的乘法器1148可以被相位旋转器代替,所述相位旋转器根据从序列生成器1144接收到的序列的相位值((4+Φπ)或者(dk+Am)以码元为基础改变控制信道信号的相位。 In this case, as in the transmitter as a multiplier, the multiplier 1140 of correlator 1148 can be replaced with a phase rotator, a phase value of the phase rotator 1144 based on the sequence received from the sequence generator to the ((4 + Φπ) or (dk + Am) phase in the symbol based channel change signal.
