Description

上行控制信息传输方法、基站和用户设备 Uplink control information transmission method, base station and user equipment

技术领域 FIELD

[0001] 本发明涉及移动通信技术领域,特别涉及到采用了载波聚合技术的LTE-Advanced 以及4G系统中上行控制信息的传输方法以及相应的基站和用户设备。 [0001] The present invention relates to the technical field of mobile communications, particularly to a transmission method using carrier aggregation LTE-Advanced systems and 4G uplink control information and the corresponding base station and user equipment.

背景技术 Background technique

[0002] 在以3GPP LTE (Long Term Evolution)为代表的下一代移动通信系统中,上行控制信道主要指物理上行控制信道(Physical Uplink ControlCHannel,PUCCH),用于用户设备(User Equipment, UE)向基站(BaseStation,BS,又称为eNB)传送上行控制信息(Uplink Control Information, UCI)。 [0002] In the next generation mobile communication system according to 3GPP LTE (Long Term Evolution) as represented, the main uplink control channel refers to a physical uplink control channel (Physical Uplink ControlCHannel, PUCCH), a user equipment (User Equipment, UE) to the base station (BaseStation, BS, also known as eNB) transmits uplink control information (uplink control information, UCI).

[0003] LTE Rel-8中共有3种UCI,包括调度请求(Scheduling Request,SR),下行混合自动请求重传(Hybrid Automatic ReQuest retransmission,HARQ)反馈(ACKnowledgement/ Negative ACKnowledgement,ACK/NACK)和信道状态指示(Channel State Indicator,CSI) 反馈。 [0003] LTE Rel-8 in total of three kinds UCI, including scheduling request (Scheduling Request, SR), a downlink hybrid automatic repeat request (Hybrid Automatic ReQuest retransmission, HARQ) feedback (ACKnowledgement / Negative ACKnowledgement, ACK / NACK) and channel status indicator (Channel state Indicator, CSI) feedback. 其中CSI又包括信道质量指示(Channel Quality Indicator,CQI),预编码矩阵指示(Precoding Matrix Indicator, PMI)和秩指示(Rank Indicator, RI)等。 And wherein the CSI includes a channel quality indicator (Channel Quality Indicator, CQI), precoding matrix indicator (Precoding Matrix Indicator, PMI) and rank indication (Rank Indicator, RI) and the like. 在LTE Rel-8 中,下行HARQ反馈和CSI反馈可在PUCCH上单独传输或复用传输;CSI反馈和/或HARQ反馈也可以在上行物理共享信道(Physical Uplink Shared CHannel,PUSCH)上与数据复用传输;对于CSI反馈,也可以在BS有特别的信道信息需求时,要求UE在BS分配的上行PUSCH 资源上进行非周期性地传输。 In LTE Rel-8, the downlink HARQ feedback and CSI feedback may be transmitted alone or multiplexed transmission on the PUCCH; CSI feedback and / or HARQ feedback may be multiplexed with data on a physical uplink shared channel (Physical Uplink Shared CHannel, PUSCH) a transmission; for feedback CSI, which may have special needs channel information BS, the UE is required to transmit the aperiodic uplink PUSCH resource allocated by the BS. LTE Rel-8中上行除了PUCCH和PUSCH外,还有信道探测参考信号(Sounding ReferenceSignal,SRS)。 LTE Rel-8 PUCCH and the uplink in addition to the PUSCH, there is a channel sounding reference signal (Sounding ReferenceSignal, SRS). LTE Rel_8中制订了一套完整的方案以解决各类上行信道和/或信号复用时对系统造成的不利影响,其中不利影响主要是指由多种上行信道和/或信号同时传输时所带来的上行峰均比的提高。 In LTE Rel_8 devised a complete solution to solve the various uplink channels and / or adverse effect on the system when the multiplex signal, wherein the main adverse effects refers to transmission from the multiple uplink channels simultaneously and / or signals carried by to uplink PAPR increase.

[0004] 3GPP LTE-Advanced系统(又称为LTE Rel-10)中引进了载波聚合技术,即:两个或两个以上的分量载波(Component Carrier, CC)聚合以支持大于20MHz的上下行传输带宽。 [0004] 3GPP LTE-Advanced system (also referred to as LTE Rel-10) introduced in the carrier aggregation technology, namely: two or more component carriers (Component Carrier, CC) aggregated to support uplink and downlink transmission is greater than 20MHz bandwidth. 在LTE Rel-10中,一个UE专有的上行PCC(Primary CC)被半静态地配置为承载该UE 的采用PUCCH传输的上行控制信息,包括下行HARQ反馈、SR和周期性CSI等。 In LTE Rel-10, the UE-specific uplink a PCC (Primary CC) is semi-statically configured PUCCH transmission using the uplink carrier of the UE control information includes a downlink HARQ feedback, SR periodic CSI and the like. 由于下行分量载波的增加,对应的下行HARQ反馈的负担也相应加重,因此LTE Rel-10中定义了两类UE,针对下行HARQ反馈量的不同分别采用不同的下行HARQ反馈传输方式。 Since the increase in downlink component carriers, the burden of the corresponding downlink HARQ feedback is correspondingly increased, so LTE Rel-10 defines two types of the UE, for the downlink HARQ feedback using different amounts of different downlink HARQ feedback transmission scheme. 当下行HARQ反馈比特数小于等于4时,这类UE将采用类似LTE Rel-8TDD下的ACK/NACKmultiplexing (又称为channel selection,信道选择)的方式来传送下行HARQ反馈;当下行HARQ反馈比特数大于4时,这类UE将采用一种新的基于离散付立叶变换扩频正交频分复用(Discrete Fourier TransformSpread Orthogonal Frequency Division Multiplex, DFT-S-OFDM) 的信号来传送下行HARQ反馈。 The number of downlink HARQ feedback bits is less than equal to 4, such UE will use the ACK similar to LTE Rel-8TDD / NACKmultiplexing (also known as channel selection, channel selection) in a manner to transmit the downlink HARQ feedback; Number of downlink HARQ feedback bits when greater than 4, the UE will use a new kind of signals based on discrete Fourier transform spread orthogonal frequency division multiplexing (discrete Fourier TransformSpread orthogonal frequency division multiplex, DFT-S-OFDM) to transmit a downlink HARQ feedback. 需要注意的是,当只有下行PCC上有下行分配(downlink assignment)时,两类UE的下行HARQ反馈方式均退化为LTE Rel_8的上行反馈方式。 Note that, when the downlink allocation (downlink assignment) on the PCC only the downlink, the UE categories are degraded downlink HARQ feedback mode as the uplink of LTE Rel_8 feedback manner. 此夕卜,LTE Rel-10上行控制信道发送机制中还将引入新的分集发送技术,如空域正交资源发送分集(SpatialOrthogonal-Resource Transmit Diversity, S0RTD)等。 This evening Bu, LTE Rel-10 uplink control channel transmission mechanism will also introduce new diversity transmission techniques, such as spatial orthogonal resource transmission diversity (SpatialOrthogonal-Resource Transmit Diversity, S0RTD) and the like. 与LTE Rel_8 类似,LTE Rel-10中也需要一套方案以解决各类上行信道和/或信号复用时对系统造成的不利影响。 And LTE Rel_8 Similarly, LTE Rel-10 is also a need to address the various types of programs upstream channel and / or adverse effect on the system when the multiplexed signal. 尽管该方案中有部分可以借鉴LTE Rel-8,但由于新的下行HARQ反馈方式和发送分集技术的引入,复用方案需要进行重新设计。 Although this embodiment can draw some of LTE Rel-8, but the new downlink HARQ feedback mode and transmit diversity techniques introduced division multiplexing scheme needs to be redesigned. 非专利文献(“Discussion on various UL transmissionconfigurations “ , Panasonic,3GPP TSG RAN WGl Meeting #61bis, Rl-103756,28th June-2nd July,2010)给出了LTE Rel_8已有的上行信道和信号的复用方案和LTE Rel-IO中的一些对应方案的构想。 Non-Patent Document ( "Discussion on various UL transmissionconfigurations", Panasonic, 3GPP TSG RAN WGl Meeting # 61bis, Rl-103756,28th June-2nd July, 2010) gives the existing LTE Rel_8 multiplexing scheme and an uplink channel signal Some ideas and programs corresponding to the LTE Rel-IO.

[0053] 为了清楚详细地阐述本发明的实现,下面给出了本发明的一些具体实施例,适用于支持载频聚合技术的无线通信系统,尤其是LTE-Advanced蜂窝移动通信系统。 [0053] In order to achieve clarity of the present invention set forth in detail, according to the present invention are given below some embodiments, the carrier is suitable for a wireless communication system supporting Frequency polymerization techniques, in particular the LTE-Advanced cellular mobile communication system. 需要说明的是,本发明不限于这些应用,而是可适用于更多其它相关的无线通信系统。 Incidentally, the present invention is not limited to these applications, but is applicable to still other related wireless communication system.

[0054] 下面参照附图对本发明的优选实施例进行详细说明,在描述过程中省略了对于本发明来说是不必要的细节和功能,以防止对本发明的理解造成混淆。 [0054] below with reference to the accompanying drawings of the preferred embodiment of the present invention will be described in detail, it is omitted unnecessary details and functions for the present invention in the course of the description, in order to prevent confusion of the understanding of the present invention.

[0055] 在LTE Re 1-8中,如果UE在某一个上行子帧(subframe)中没有数据传输,但是有CSI要传输,CSI将以format 2的格式在PUCCH上传输;同样如果UE有下行HARQ反馈要传输,下行HARQ反馈将以formatla/lb的格式在PUCCH上传输。 [0055] In LTE Re 1-8, if the UE did not transmit data in one uplink subframe (subframe), but it has to be transmitted CSI, CSI format format 2 will be transmitted on the PUCCH; Similarly if the UE has downlink HARQ feedback to be transmitted, the downlink HARQ feedback will formatla / lb transmission formats in the PUCCH. 当CSI与下行HARQ反馈需要复用传输时,有两种方案:当无线资源控制(Radio Resource Control,RRC)信令配置simultaneousAckNackAndCQI为假时,CSI信息将被丢弃,只有下行HARQ反馈信息将以format la/lb的格式在PUCCH上单独传输;如果配置simultaneousAckNackAndCQI为真时,又分为以下两种情况。 When the downlink CSI HARQ feedback needs multiplexing transmission, there are two options: When the RRC (Radio Resource Control, RRC) signaling false when configured simultaneousAckNackAndCQI, CSI information is discarded, and only the downlink HARQ feedback information format will la / lb transmission formats separately on the PUCCH; simultaneousAckNackAndCQI true if configured, is divided into the following two cases. 当系统采用常规(normal)循环前缀(Cyclic Prefix, CP)时, 下行HARQ反馈将和CSI —起以format 2a/2b的格式在PUCCH上传输,其中下行HARQ反馈的1个或2个比特的信息将采用二进制相移键控(BinaryPhase Shift Keying, BPSK)或正交相移键控(Quadrature Phase ShiftKeying, QPSK)被调制到对应上行子帧的每一个时隙(slot)的PUCCH格式2格式的第二列参考信号上;当系统采用扩展循环前缀(extended CP)时,由于此时每个时隙内PUCCH格式2格式只有一列参考信号,难以将下行HARQ反馈信息以相位差的形式嵌入在参考信号中,此时UE将把下行HARQ反馈和CSI联合编码,形成20比特的编码数据,然后按扩展CP的PUCCH格式2的格式进行发送。 When the system is conventional (normal) cyclic prefix (Cyclic Prefix, CP), a downlink HARQ feedback to and CSI - information from format format 2a / 2b in the PUCCH transmission, wherein the downlink HARQ feedback is one or two bits the use of binary phase shift keying (BinaryPhase shift keying, BPSK) or quadrature phase shift keying (quadrature phase ShiftKeying, QPSK) modulated onto each time slot (slot) of an uplink subframe corresponding to PUCCH format 2 format the two reference signal; when the system uses an extended cyclic prefix (extended CP), each time slot since at this time PUCCH format 2 format only a reference signal is difficult to downlink HARQ feedback information embedded in the reference phase difference signal in the form of in this case UE will downlink HARQ feedback CSI and jointly encoded, the encoded data is formed of 20 bits, and the format of extended CP PUCCH format 2 are transmitted.

[0056] 实施例1 : [0056] Example 1:

[0057] LTE Rel-8的下行HARQ反馈与CSI的复用传输方式在LTE Rel-IO中依然适用,然而考虑到LTE Rel-IO中下行HARQ反馈比特数的增加和有可能会对PUCCH格式2格式引入的SORTD分集发送技术,下行HARQ反馈与CSI复用的方式需要进一步优化。 [0057] LTE Rel-8 downlink HARQ feedback CSI and multiplexing transmission is still applicable in LTE Rel-IO, however, considering the downlink in LTE Rel-IO bits are increased by the number of HARQ feedback, and there might be PUCCH format 2 SORTD introduce diversity technology format transmission, the downlink CSI HARQ feedback and multiplexing method requires further optimization. 为此,本发明提出了的一种优化复用方法,该方法包括以下步骤:将原始下行HARQ反馈信息映射为多组下行HARQ反馈信息,每组下行HARQ反馈信息与多根天线之一相关联;以及利用相应天线上不同的PUCCH资源,发送CSI和经映射的各组下行HARQ反馈信息。 To this end, the present invention proposes an optimization of the multiplexing method, the method comprising the steps of: the original downlink HARQ feedback information mapped to a plurality of groups of downlink HARQ feedback information, each downlink HARQ feedback information associated with a plurality of one of the antennas ; and a feedback information using the corresponding PUCCH resource on a different antenna, transmitting each set of downlink HARQ CSI and mapped. 与该优化复用方法相应的,本发明还提出了一种解复用方法,该方法包括以下步骤:接收与多根发射天线相对应的不同的PUCCH资源上的CSI和经映射的多组下行HARQ反馈信息,每组下行HARQ反馈信息与多根天线之一相关联;以及将经映射的多组下行HARQ反馈信息解映射为原始下行HARQ 反馈信息。 Optimization of the respective multiplexing method, the present invention also proposes a demultiplexing method comprising the steps of: a plurality of sets of downlink CSI and mapped on different PUCCH resources to receive a plurality of transmit antennas corresponding to the HARQ feedback information, each downlink HARQ feedback information associated with a plurality of one of the antennas; and a plurality of sets of downlink HARQ feedback information mapped to the original downlink demapped HARQ feedback information. 以下,以两天线SORTD分集方式为例对本发明此优化方法进行描述。 Hereinafter, the two-antenna diversity method SORTD an example of this optimization method of the present invention will be described.

[0058] 如图1所示,采用了SORTD方式后,CSI将以PUCCH格式2的格式在每一根上行发射天线上分别采用不同的PUCCH格式2资源进行传输。 After [0058] As shown, an embodiment using SORTD, CSI format will PUCCH format 2 in each of the uplink transmit using different resources of PUCCH format 2 for transmission on antenna. 本实施例中以下假设BS通过RRC 将UE的simultaneousAckNackAndCQI状态配置为真,即允许下行HARQ反馈与CSI复用。 The following embodiment is assumed by the BS simultaneousAckNackAndCQI RRC state of the UE configured as true, i.e., to allow the downlink HARQ feedback CSI and the multiplexing of the present embodiment.

[0059] 当采用常规CP,且需要与CSI复用的下行HARQ反馈比特数为2时,可以采用图1 (a)的方法,直接将两比特的下行HARQ反馈重复后调制到每根天线对应的每一个PUCCH 资源的每一个时隙的第二列参考信号上去;也可以类似图1(b)的方法,先将两比特的下行HARQ反馈扩展成三比特,如将(al,a2)扩展为(al,a2,a3 = al xor a2),其中xor为异或操作,然后再将三比特(al,a2,a3)按照图1(b)的顺序调制到不同PUCCH资源不同时隙的第二列参考信号上去。 [0059] When the number of feedback bits conventional the CP, and needs CSI multiplexed downlink HARQ is 2, may be employed FIG. 1 (a) method of direct two-bit downlink HARQ feedback after repeat modulation to each of the antennas corresponding to the second column of the reference signal for each time slot for each PUCCH resources up; may be similar to the method of FIG 1 (b), the first two bits of the downlink HARQ feedback extended to three bits, as will (al, a2) extended is (al, a2, a3 = al xor a2), where xor is an XOR operation, and then three bits (al, a2, a3) modulating different PUCCH resources to different time slots in the order of FIG. 1 (b) of the first up two reference signals. 应当注意的是,异或操作仅仅是可以实现下行HARQ反馈信息扩展的一示例方式,所属领域技术人员还易于想到采用其他逻辑运算操作来扩展下行HARQ反馈fn息ο It should be noted that the XOR operation can be realized simply extended downlink HARQ feedback information according to an example embodiment, those skilled in the art also readily conceivable to employ other logical arithmetic operation to extend the downlink HARQ feedback information ο fn

[0060] 当解复用时,从与每根发射天线对应的每一个PUCCH资源的每一个时隙的第二列参考信号直接解调得到两个下行HARQ反馈比特(al,a2),再将两组下行HARQ反馈比特(al, a2)合并为一组;或者从每一个PUCCH资源的每一个时隙的第二列参考信号解调得到(al, a2, a3 = al xor a2)的顺序排列,再根据a3与(al,a2)的异或关系,将按图1 (b)的顺序排列的(al, a2, a3)合并为一组(al, a2)。 [0060] When demultiplexing, to give two downlink HARQ feedback bits (al, a2) from direct demodulation reference signal and a second row each time slot of each of a PUCCH resource corresponding to each transmit antenna, then two downlink HARQ feedback bits (al, a2) combined into a group; or to give (al, a2, a3 = al xor a2) arranged in this order from the second column demodulation reference signal for each time slot for each PUCCH resource , then according to the relationship between a3 XOR (al, a2) of, in sequence in FIG. 1 (b) arrangement (al, a2, a3) combined into a group (al, a2).

[0061 ] 当采用常规CP,且需要与CSI复用的下行HARQ反馈比特数为4 (比特记为al,a2, a3, a4)时可以按照图1(c)的方法,每根天线对应的PUCCH资源的两个时隙的第二列参考信号调制相同的两个比特,如第一根天线对应的PUCCH资源的两个时隙的第二列参考信号调制(al,a2),第二根天线对应的PUCCH资源的两个时隙的第二列参考信号调制(a3,a4); 也可以按照图1(d)的方法,两根天线交叉调制四个下行HARQ反馈比特,以进一步获取天线分集增益。 [0061] When the HARQ feedback bits conventional the CP, and needs CSI multiplexed downlink 4 (bits denoted by al, a2, a3, a4) when the can according to FIG. 1 (c) of the method, each antenna corresponding to the second column of the reference signal PUCCH resources two slots of the same two modulated bit, a second root modulated reference signal as the second column of the two slots of a first antenna corresponding to PUCCH resource (al, a2), the second column of the reference signal modulated corresponding to the two slot antennas PUCCH resource (a3, a4); may be (d), the method, two antennas four cross-modulation bit downlink HARQ feedback according to FIG. 1, the antenna further obtain diversity gain.

[0063] 当采用常规CP,且需要与CSI复用的下行HARQ反馈比特数为3时,一种方法是可以直接采用图1(b)的方式,另外可以采用图1(c)和(d)的方式,只是(a3,a4)简并为一个比特a3,采用BPSK调制。 [0063] When the CP conventional, and the number of downlink HARQ feedback needs CSI bit multiplexed is 3, a method can be used directly FIG. 1 (b), and the other may be employed in FIG. 1 (c) and (d ) manner except (a3, A4) degenerate as a bit a3, using BPSK modulation.

[0065] 当采用扩展CP,且需要与CSI复用的下行HARQ反馈比特数为2时,可以将这两个比特与CSI联合编码形成20比特的编码数据,然后按扩展CP的PUCCH格式2的格式在两根上行发射天线上采用不同的PUCCH资源进行发送;也可以先将两比特的下行HARQ反馈扩展成三比特,如将(al,a2)扩展为(al,a2,a3 = al xor a2),其中xor为异或操作,然后再将三比特(al, a2, a3)分成两组(al, a2),(a2, a3),分别与CSI联合编码形成20比特的编码数据,然后分别按扩展CP的PUCCH格式2的格式在两根上行发射天线上采用不同的PUCCH 资源进行发送。 [0065] When feedback bits using an extended CP, and requires a CSI HARQ downlink multiplexing is 2, these may be formed of two encoded data bits 20 bits jointly coded CSI, and then press the extended CP PUCCH format 2 format employed in the two different transmit antennas uplink PUCCH resource for transmission; two bits may be first expanded into three downlink HARQ feedback bits, such as the (al, a2) is extended (al, a2, a3 = al xor a2 ), where xor is an XOR operation, and then three bits (al, a2, a3) divided into two groups (al, a2), (a2, a3), 20 bits of encoded data are formed jointly coded CSI, respectively, then the format of an extended CP PUCCH format 2 is different in the two PUCCH resources for sending uplink transmission antennas.

[0066] 相应地,当解复用时,接收来自两根上行发射天线的联合编码数据,将该数据进行联合解码,得到CSI和两组下行HARQ反馈比特(al,a2),再将两组下行HARQ反馈比特(al, a2)合并为一组;或者接收来自两根上行发射天线的联合编码数据,将该数据进行联合解码,得到CSI和两组下行HARQ反馈比特(al,a2),(a2,a3),再根据a3与(al,a2)的异或关系,将(al,a2),(a2,a3)合并为一组(al,a2)。 [0066] Accordingly, when demultiplexing received from the two jointly encoded uplink data transmit antennas, jointly decoding the data, to obtain downlink CSI HARQ feedback and two bits (al, a2), then the two groups downlink HARQ feedback bits (al, a2) combined into a group; or jointly receiving uplink encoded data from the two transmit antennas jointly decoding the data, to obtain downlink CSI HARQ feedback and two bits (al, a2), ( A2, a3), then according to the relationship between a3 XOR (al, a2) of the (al, a2), (a2, a3) combined into a group (al, a2).

[0086] LTE Rel-8的下行HARQ反馈与CSI的复用传输方式在LTE Rel-IO中依然适用, 然而考虑到LTE Rel-IO中下行HARQ反馈比特数的增加,下行HARQ反馈与CSI复用的方式需要进一步优化。 [0086] downlink LTE Rel-8 HARQ feedback and CSI multiplexing transmission is still applied in LTE Rel-IO are, however, considering the LTE Rel-IO downlink to increase the number of HARQ feedback bits, a downlink HARQ feedback CSI multiplexing the approach requires further optimization. 为此,本发明提出了的一种优化复用方法,该方法包括以下步骤:将下行HARQ反馈信息分为第一部分和第二部分;将下行HARQ反馈信息的第一部分与CSI进行联合编码,从而将CSI和下行HARQ反馈信息的第一部分复用在一起;以及将下行HARQ反馈信息的第二部分以参考信号调制的方式与CSI复用在一起。 To this end, the present invention proposes an optimized multiplexing method, the method comprising the steps of: downlink HARQ feedback information into a first portion and a second portion; a first portion of the CSI of the downlink HARQ feedback information is jointly encoded, whereby the first partial-CSI feedback information and downlink HARQ multiplexed together; second portion of the reference signal and the modulated manner CSI HARQ feedback information and the downlink multiplexed together. 与该优化复用方法相应的,本发明还提出了一种解复用方法,该方法包括以下步骤:接收下行HARQ反馈信息的第一部分与CSI的联合编码结果,同时对下行HARQ反馈信息的第二部分以参考信号调制的方式与CSI 复用在一起的部分进行解调,得到下行HARQ反馈信息的第二部分;对下行HARQ反馈信息的第一部分与CSI通过联合编码方式复用传输的部分进行联合解码,得到下行HARQ反馈信息的第一部分与CSI ;以及将前两者组成完整下行HARQ反馈,同时也获得了CSI。 Optimization of the respective multiplexing method, the present invention also proposes a demultiplexing method comprising the steps of: receiving a jointly encoded downlink HARQ feedback information from the first part of the CSI, while the feedback information of downlink HARQ two parts to the reference signal and the partial-CSI modulated manner multiplexed together, obtained by demodulating the second portion of the downlink HARQ feedback information; performed with a first portion of the transmission portion of the downlink CSI HARQ feedback information is combined by multiplexing encoding joint decoding, to obtain a first portion of the downlink CSI HARQ feedback information; and the first two form a complete downlink HARQ feedback, but also access to the CSI.

[0087] 下面以系统采用常规CP,且需要与CSI复用的下行HARQ反馈比特数为4(记为al,a2,a3,a4)为例进行描述。 [0087] In the following system using a conventional CP, and the number of downlink HARQ feedback bits multiplexed CSI needs to 4 (referred to as al, a2, a3, a4) will be described as an example. 此时的下行HARQ反馈可以分成两组(al,a2)和(a3,a4),其中一组与CSI对应的信息比特进行联合编码(比如采用与LTE Rel-SCSI编码类似的Reed Muller码(20,A))形成20比特的编码数据,放入待发送的PUCCH格式2b的非参考信号部分;另一组调制为QPSK符号,然后调制到待发送的PUCCH格式2b的每一个时隙的第二列参考信号上去;接着将生成好的PUCCH格式2b格式的信号发送即可实现4比特的下行HARQ 反馈信息与CSI的复用传输。 At this time, the downlink HARQ feedback may be divided into two groups (al, a2) and (a3, a4), wherein a group corresponding to the CSI information bits jointly encoding (such as the use of LTE Rel-SCSI Reed Muller code encoding similar (20 , a)) is formed of 20 bits of encoded data, the non-reference signal to be transmitted into the portion of the PUCCH format 2b; the other set of modulation symbols to QPSK, and the modulation format to the PUCCH to be transmitted each time slot of a second 2b reference column signal up; then generate good signal transmission format of the PUCCH format 2b can realize 4 bit downlink CSI HARQ feedback information multiplexing transmission.

[0088] 相应地,在解复用时,BS从PUCCH格式2b的数据部分提取出下行HARQ反馈第一部分与CSI的联合编码数据,对其进行联合解码,从而得到下行HARQ反馈的第一部分(al,a2) 与CSI ;并且,BS从PUCCH格式2b的参考信号部分解调出下行HARQ反馈的第二部分(a3, a4)。 [0088] Accordingly, when demultiplexing, the BS extracts the data portion from the PUCCH format 2b, the first portion of the downlink HARQ feedback CSI and the jointly encoded data, joint decoding them to obtain a first portion of the downlink HARQ feedback (Al , a2) with the CSI; and, BS PUCCH demodulation reference signal part from the format of the second portion 2b of the downlink HARQ feedback (a3, a4). 最后,BS将这两部分组合即获得了完整的下行HARQ反馈(al,a2,a3,a4)以及CSI。 Finally, BS combination of these two parts is obtained i.e. a complete downlink HARQ feedback (al, a2, a3, a4) and CSI.

[0089] 本发明还提出了的一种优化复用方法,该方法包括以下步骤:将下行HARQ反馈信息进行压缩;将压缩后的下行HARQ反馈信息与CSI进行联合编码;以及利用PUCCH资源发送联合编码后的CSI和压缩后的下行HARQ反馈信息。 [0089] The present invention further provides a method for optimizing reuse, the method comprising the steps of: compressing the downlink HARQ feedback information; and the compressed downlink HARQ feedback information CSI jointly encoded; and using the PUCCH resource for transmitting joint after the downlink CSI and compression encoded HARQ feedback information. 与该优化复用方法相应的,本发明还提出了一种解复用方法,该方法包括以下步骤:接收PUCCH资源上的下行HARQ反馈信息,所述下行HARQ反馈信息是CSI和经压缩的下行HARQ反馈信息的联合编码结果;对所述下行HARQ反馈信息进行联合解码,分别得到CSI和经压缩的下行HARQ反馈信息;对经压缩的下行HARQ反馈信息进行解压缩,得到原始下行HARQ反馈信息。 Optimization of the respective multiplexing method, the present invention also proposes a demultiplexing method comprising the steps of: receiving a downlink HARQ feedback information on a PUCCH resource, the downlink HARQ feedback information is compressed downlink CSI and jointly encoding result HARQ feedback information; the downlink HARQ feedback information jointly decoding, respectively, and the compressed downlink CSI HARQ feedback information; downlink HARQ feedback information for the compressed decompressing obtain the original downlink HARQ feedback information.

[0090] 下面以系统采用扩展CP,且需要与CSI复用的下行HARQ反馈比特数大于2为例进行解释。 [0090] In the following system using the extended CP, and the number of downlink HARQ feedback bits multiplexed CSI needs greater than 2 will be explained as an example. 此时可以分成三种情况:当CSI对应的比特数和下行HARQ反馈比特数之和不超过PUCCH格式2支持的最大比特数时(如11或13,分别考虑了LTE Rel-8目前PUCCH格式2 可以支持的比特数或PUCCH编码器最大可能支持的比特数),可以考虑将CSI与下行HARQ 反馈联合编码(比如采用与LTE Rel-8CSI编码类似的Reed Muller码(20,A)),然后按扩展CP的PUCCH格式2的格式进行传输;当CSI对应的比特数和下行HARQ反馈比特数之和超过PUCCH格式2支持的最大比特数时,可以考虑将下行HARQ反馈状态进行各种压缩操作,如空域捆绑(spatial bundling),时域捆绑(time domain bundling)和跨CC捆绑等, 之后产生两个比特,与CSI联合编码后按扩展CP的PUCCH格式2的格式进行传输;也可以不管CSI对应的比特数和下行HARQ反馈比特数之和是多少,直接将下行HARQ反馈状态进行压缩操作产生两个比特,与CSI联合编码后按扩展CP的 At this time, it can be divided into three cases: when (e.g., 11 or 13 bits corresponding to the CSI and the maximum number of bits of the number of downlink HARQ feedback bits and does not exceed the support PUCCH format 2, are considered separately the current LTE Rel-8 PUCCH format 2 can support the number of bits or PUCCH encoder maximum number of bits may support), may be considered CSI downlink HARQ feedback joint encoding (such as the use of LTE Rel-8CSI encoding similar Reed Muller code (20, a)), and then press extended CP format for transmission of PUCCH format 2; and when the maximum number of bits and the number of bits corresponding to a downlink CSI HARQ feedback bits and the number of PUCCH format 2 over support, consider downlink HARQ feedback state various compression operations, such as airspace bundle (spatial bundling), time domain bundling (time domain bundling) and cross-CC bundling, after generating the two bits, the CSI is transmitted jointly coded with the format of an extended CP PUCCH format 2; and the corresponding CSI may matter the number of bits and the number of downlink HARQ feedback bits and how much the downlink HARQ feedback directly compressed state operation generates two bits, with the combined CSI encoded by the extended CP PUCCH格式2的格式进行传输。 PUCCH format 2 for transmission format.

[0091] 相应地,在解复用时,可以通过对接收到的联合编码结果进行联合解码得到CSI 以及经压缩的下行HARQ反馈信息。 [0091] Accordingly, when jointly encoding result of the demultiplexing to be combined by the received and decoded the compressed downlink CSI HARQ feedback information. 然后,对经压缩的下行HARQ反馈信息进行解压缩,得到原始下行HARQ反馈信息。 Then, the compressed downlink HARQ feedback information is decompressed to obtain the original downlink HARQ feedback information.

[0092] 所属领域技术人员易于想到,可以将以上两种优化复用方式结合使用,以进一步对复用进行优化。 [0092] Those skilled in the art will readily occur, two or more kinds may be used to optimize multiplex manner combined to further optimize multiplexed.

[0106] 实施例3 : [0106] Example 3:

[0107] LTE Re 1-8 中BS 通过RRC 配置simultaneousAckNackAndCQI 以决定UE 能否将下行HARQ反馈与CSI共同传输。 [0107] LTE Re 1-8 by the BS UE RRC configuration simultaneousAckNackAndCQI to determine whether the downlink HARQ feedback transmitted together with the CSI. 在LTE Rel-IO中,由于每一个下行CC均需要反馈对应该CC的CSI,并且这些CSI必须得在同一个UE专有的上行CC上传输。 In LTE Rel-IO, since each of the downlink CC and the feedback CSI are required have to be transmitted to the CSI CC, the same in a UE-specific uplink CC. 这将造成下行HARQ反馈与CSI复用传输的几率大大增加。 This will result in downlink HARQ feedback and CSI chance multiplexing transmission is greatly increased. 然而,到目前为止,现有的下行HARQ反馈与CSI复用传输的方案都不完美,都会对下行HARQ反馈和/或CSI的传输质量造成一定的影响。 However, to date, the existing downlink HARQ feedback and CSI multiplexing transmission scheme is not perfect, it will have a certain impact on the downlink HARQ feedback and / or transmission quality CSI. LTE Rel-8中可以考虑丢弃CSI以保全下行HARQ反馈,然而考虑到LTE Rel-IO中两者复用几率的大大增加,经常丢弃CSI也是不可取的。 LTE Rel-8 can be considered to preserve the discarded downlink CSI HARQ feedback, however, take into account both in LTE Rel-IO multiplexed probability greatly increased, often to drop the CSI is not desirable. 考虑到LTE Rel-IO中下行CC可分为PCC与非PCC,CSI反馈中可分为CQI、PMI、RI, CQI还可分为宽带CQI、子带CQI,因此可以对这些不同CC上的不同CSI反馈类型与下行HARQ反馈的复用方式实行差异对待,即比较重要的CSI反馈与下行HARQ反馈复用传输,不太重要的CSI反馈直接丢弃。 Considering the LTE Rel-IO can be divided into downlink CC and non-PCC PCC, CSI feedback can be divided into CQI, PMI, RI, CQI can be divided into wideband CQI, subband CQI, so these can be different for the different CC type of CSI feedback multiplexing mode and a downlink HARQ feedback implementation differences are treated, i.e., more important CSI feedback downlink HARQ feedback multiplexing transmission, less important CSI feedback discarded.

[0108] 为此,本发明提出了一种将下行HARQ反馈和CSI进行复用的方法,其特征在于:不同下行CC对应的CSI和/或不同类型的CSI与下行HARQ反馈的复用方式不同。 [0108] To this end, the present invention provides a HARQ feedback of the downlink CSI and multiplexing method, wherein: different CSI corresponding to different downlink CC and / or different types of downlink CSI HARQ feedback multiplexing method . 这一策略既可以通过BS发送给UE的额外的UE专有的RRC信令进行显式(explicit)的设置,也可以按照隐式(implicit)的方式进行约定。 This strategy may be sent by the BS to the UE additional UE-specific RRC signaling is provided explicit (Explicit) may be performed in a manner implicit agreement (Implicit) a. 以下通过一些例子具体解释这一方法: The following specifically explained with some examples of this approach:

[0109] 例如,BS可以通过RRC将UE的simultaneousAckNackAndCQI配置为仅对下行PCC或其他某一个或某一组CC所对应的CSI反馈有效,即当需要共同传输下行HARQ反馈和CSI,且该CSI为下行PCC或其他某一个或某一组CC所对应的CSI时,下行HARQ反馈和CSI 的复用传输遵循simultaneousAckNackAndCQI,也艮口是simultaneousAckNackAnd-CQI 为真时,采用上述的或协议已经规定的各种方法将下行HARQ反馈和CSI复用传输;simultaneousAckNackAndCQI为假时,丢弃CSI,仅仅传输下行HARQ反馈。 [0109] For example, the BS may configure the simultaneousAckNackAndCQI RRC of the UE through a downlink PCC is only one or other, or a group corresponding CC CSI feedback effective, i.e., when the need to work together and transmitting the downlink CSI HARQ feedback, and the CSI is PCC or other downstream of one or a group of CC corresponding to CSI, the downlink CSI HARQ feedback and multiplexing transmission follows simultaneousAckNackAndCQI, Burgundy port is also simultaneousAckNackAndCQI is true, various protocols have been described above or predetermined the method of the downlink CSI HARQ feedback and multiplexing transmission; simultaneousAckNackAndCQI false when discarded CSI, transmitting only downlink HARQ feedback. 针对simultaneousAckNackAndCQI配置无效的那些CC所对应的CSI与下行HARQ反馈同时出现在一个上行帧中时,一律丢弃CSI,仅仅传送下行HARQ反馈。 When the configuration is invalid for simultaneousAckNackAndCQI those corresponding CC downlink CSI HARQ feedback in a simultaneous uplink frame, it will be discarded CSI, downlink HARQ feedback is transmitted only. 对于因丢弃CSI造成吞吐量损失的CC,BS可以考虑通过调度非周期性CSI汇报的方式让UE将这些CC对应的CSI反馈上来。 For CC throughput loss caused by discarding the CSI, BS may be considered by scheduling aperiodic CSI UE to report the manner corresponding to these CC up CSI feedback.

[0110] 又例如,BS可以通过RRC将UE的simultaneousAckNackAndCQI配置为仅对某一类的CSI反馈有效,比如只对宽带(wideband)反馈有效,而对子带(subband)反馈无效。 [0110] and e.g., BS by simultaneousAckNackAndCQI RRC of the UE configured only for certain type of CSI feedback effective, for example, only broadband (Wideband) effective feedback, and subband (Subband) feedback invalid. 这样当下行CC的宽带反馈与下行HARQ反馈需要共同传输时,如果simultaneousAckNackAndCQI 配置为真,则UE采用上述的或协议已经规定的各种方法将下行HARQ反馈与CSI —起传输给BS ;如果simultaneousAckNackAndCQI配置为假,UE丢弃CSI,仅仅向BS传送下行HARQ 反馈。 In this way the downlink CC wideband feedback downlink HARQ feedback transmitted together need, if true simultaneousAckNackAndCQI configured, the UE various methods or protocols described above have been predetermined and the downlink HARQ feedback CSI - starting transmission to the BS; if the configuration simultaneousAckNackAndCQI is false, UE discards the CSI, the downlink HARQ feedback is transmitted only to the BS. 当下行CC的子带反馈与下行HARQ反馈需要共同传输时,一律丢弃CSI,仅仅向BS传送下行HARQ反馈。 When the downlink CC and the downlink subband feedback required HARQ feedback transmitted together, the CSI will be dropped, only the downlink to the BS transmits HARQ feedback.

[0111] 以上两种配置方法也可以综合使用,即BS将UE的simultaneousAckNackAndCQI 配置为仅对某些CC的某些CSI反馈有效,具体方法与上面所述一致。 [0111] the above two configuration methods can also combine, i.e. BS of the UE configured only for certain simultaneousAckNackAndCQI some effective feedback CSI CC, consistent with the above specific method. [0112] 通过这一方法,即能保证重要CSI反馈不会被丢弃,也可以保证下行HARQ反馈不会经常因为要与CSI反馈复用造成严重的性能下降。 [0112] By this method, i.e., the CSI feedback can ensure significant not discarded, may not always guaranteed because the downlink HARQ feedback CSI to be fed back to the multiplexing serious performance degradation.

[0113] 由于该方案只是对特定类型和/或特定CC所对应的CSI进行选择性复用而不改变下行HARQ反馈与特定类型或特定CC所对应的CSI的具体复用方式,该方案所对应的解复用方法仍可以沿用现有技术的解复用方法或采用前述实施例中的解复用方法,或者不必采用解复用方法(对应于CSI全部被丢弃的情形)。 [0113] Since the program is only selective for a particular type and / or specific CC corresponding to changes in the downstream multiplexed CSI HARQ feedback and a specific type or a specific CC corresponding CSI specific manner without multiplexing, the program corresponding the demultiplexing method may still use the existing art or demultiplexing method using the demultiplexing method in the embodiment, or having to use demultiplexing method (corresponding to the case where all discarded CSI).

[0114]【硬件功能实现】 [0114] [hardware] function realization

[0115] 为实现本实施例的对CSI进行选择性复用的策略,只需在现有技术或前述用户设备中加入simultaneousAckNackAndCQI有效性配置单元和CSI区分单元。 CSI selective strategy multiplexing [0115] To achieve the present embodiment, simply by adding simultaneousAckNackAndCQI validity hive and CSI in the prior art distinguishing unit or the user equipment. 所述simultaneousAckNackAndCQI有效性配置单元用于,通过显式设置或隐式约定的方式,配置simultaneousAckNackAndCQI对哪些CC对应和/或哪些类型的CSI有效。 The validity simultaneousAckNackAndCQI configuration unit for setting by explicitly or implicitly agreed manner, which effectively simultaneousAckNackAndCQI arranged corresponding to CC and / or what type of CSI pair. 所述CSI区分单元用于,区分simultaneousAckNackAndCQI对其有效或无效的CSI。 The CSI distinguishing unit for distinguishing the simultaneousAckNackAndCQI CSI its valid or invalid.

[0116] 实施例4 : [0116] Example 4:

[0117] 与LTE Re 1-8中类似,LTE Rel-IO中的下行HARQ反馈与SRS能否同时传输也可以受RRC信令ackNackSRS-Simultaneous Transmission的配置。 [0117] Similar to the LTE Re 1-8, the downlink HARQ feedback in LTE Rel-IO whether the SRS may be transmitted simultaneously by the RRC signaling ackNackSRS-Simultaneous Transmission configuration. 如果ackNackSRS-Simultaneous Transmission 为假,每当下行HARQ 反馈与SRS 在同一上行子帧中出现,UE将丢弃SRS,仅传输下行HARQ反馈。 If ackNackSRS-Simultaneous Transmission is false whenever downlink HARQ feedback and appearing in the same SRS uplink sub-frame, the UE will discard the SRS, downlink HARQ feedback is transmitted only. 如果ackNackSRS-Simultaneous Transmission为真,当UE需要传输的下行HARQ反馈比特数小于等于4时,UE的下行HARQ 反馈传输方法为基于PUCCH格式Ib的信道选择,此时下行HARQ反馈将采用与LTE Rel-8 相同的截短的PUCCH格式Ib格式与SRS复用传输;当UE需要传输的下行HARQ反馈比特数大于4时,UE的下行HARQ反馈传输方法将采用基于DFT-S-OFDM的信号,此时下行HARQ反馈与SRS复用传输的方法将在下面进行具体描述。 If ackNackSRS-Simultaneous Transmission is true, when the UE needs to transmit the number of bits in the downlink HARQ feedback is equal to less than 4, the downlink HARQ feedback transmission UE channel selection method based on the PUCCH format Ib is, at this time we will use the downlink HARQ feedback LTE Rel- 8 PUCCH format Ib same format with truncated SRS multiplexing transmission; when the number of downlink HARQ feedback bits to be transmitted is greater than the UE 4, UE downlink HARQ feedback transmission method based DFT-S-OFDM signal, which lower SRS multiplexing HARQ feedback line will be specifically described below with reference transmission method.

[0118] 在LTE Rel-IO中,在没有数据传输的上行子帧中,如果UE需要传输的下行HARQ 反馈比特数大于4时,这类UE将采用一种新的基于DFT-S-OFDM的信号来传送下行HARQ反馈,具体结构如图14(显示了一个上行子帧的一个时隙,可参考非专利文献R1-103506)所示。 When [0118] In LTE Rel-IO, the uplink subframe is no data transmission, downlink HARQ feedback bits if the UE needs to transmit is greater than 4, the use of such a new UE based on the DFT-S-OFDM downlink HARQ feedback signal is transmitted, a specific configuration of FIG. 14 (a shows an uplink slot of a subframe, may refer to Non-Patent Document R1-103506) FIG. 下行HARQ反馈比特首先通过前向纠错码(这里的前向纠错码可以是LTERel-8中已有的Reed Muller码(32,0))编码产生32比特,然后经过速率匹配(rate match)产生48个比特;随后这些编码后比特经过扰码处理后映射为24个QPSK调制符号,每12个符号经过正交码(OrthogonalCover Code, 0CC)扩展到每个时隙的一个资源块的5个DFT-S-OFDM符号上去。 First downlink HARQ feedback bits by forward error correction codes (forward error correction codes herein may be LTERel-8 already in the Reed Muller code (32,0)) the code generator 32 bits, then after rate matching (rate match) generating 48 bits; these coded bits then scrambled through mapping of 24 QPSK modulation symbols, each symbol through the 12 orthogonal codes (OrthogonalCover code, 0CC) extended to a resource block of each slot 5 DFT-S-OFDM symbols up. 该结构中的2个参考信号(Reference Signal, RS)分别占用第2个(符号1)和第6个(符号5) DFT-S-OFDM符号。 The structure in which two reference signal (Reference Signal, RS), respectively, occupies the second (numeral 1) and 6 (reference 5) DFT-S-OFDM symbols.

[0119] 图14没有考虑下行HARQ反馈与SRS复用的情况,图15考虑到某一个子帧的第2 个时隙下行HARQ反馈与SRS复用的情况,将最后一个DFT-S-OFDM符号(符号6)留给SRS 使用,而不用来传送下行HARQ反馈。 [0119] FIG. 14 does not consider the case of downlink HARQ feedback SRS multiplexing, taking into account the 15 subframes of a second slot and the downlink HARQ feedback multiplexing SRS, the last DFT-S-OFDM symbols (reference 6) left SRS used without downlink HARQ feedback for transmission. 这一操作对下行HARQ反馈的影响是下行HARQ反馈发送结构中的OCC序列由原来的长度为5变为长度为4,此外该子帧的第2个时隙能复用的UE的下行HARQ反馈的数量也由原来的5个变为4个。 Downlink HARQ downlink HARQ feedback effect of this operation is a downlink HARQ feedback transmission OCC sequence structure from the original length becomes a length of 4 to 5, the subframe in addition second timeslot UE can be multiplexed feedback number from the original five becomes four.

[0120] 图14和图15均考虑的是系统采用常规CP的情况,未考虑系统使用扩展CP。 [0120] Figures 14 and 15 are contemplated that the system uses a normal CP case, the system does not consider the use of the extended CP. 为此,本发明提出了一种扩展CP下的将下行HARQ反馈和SRS进行复用的方法,包括以下步骤:将下行HARQ反馈信息扩展到具有6个DFT-S-OFDM符号的DFT-S-OFDM信号格式的前5个DFT-S-OFDM符号中的4个上,其中RS在第3个DFT-S-OFDM符号上;将SRS映射为所述DFT-S-OFDM信号格式的最后一个DFT-S-OFDM符号。 To this end, the invention proposes an extended CP case of the downlink HARQ feedback and SRS multiplexing method, comprising the steps of: spreading the downlink HARQ feedback information to the DFT-S- having 6 DFT-S-OFDM symbols the first five symbol DFT-S-OFDM signal OFDM format 4, wherein the RS in the first three symbol DFT-S-OFDM; an SRS is mapped to the last DFT DFT-S-OFDM signal format -S-OFDM symbols.

[0121] 下面举例对上述方法进行说明。 [0121] The following are examples of the above-described method will be described. 当系统采用扩展CP时,由于此时上行子帧每一个时隙仅有6个DFT-S-OFDM符号,此时的下行HARQ反馈所在的上行子帧的2个时隙都可以考虑采用如图16或图17所示的结构,与图15的区别是每个时隙的第7个DFT-S-OFDM符号(符号6)的位置不是如常规CP那样被留出的,而是不存在的。 When the system uses the CP extension, since at this time only six symbol DFT-S-OFDM uplink sub-frame for each time slot, the downlink HARQ uplink sub-feedback case where two slots of a frame may be considered in FIG. 16 or the structure shown in FIG. 17, FIG. 15 is the difference of each slot 7 DFT-S-OFDM symbols (symbol 6) of the position is not as regular as CP is left out, but does not exist . 图16与图17的差异在于每个时隙中第二个参考信号的时域位置不同,图17所示的放置方法可以一定程度上提高所述情况下的信道估计精度。 Different Difference FIG. 16 and 17 wherein each slot of the second reference signal time domain location, placement method shown in Figure 17 can improve the channel estimation accuracy in the case where a certain extent.

[0122] 当系统采用扩展CP,并且考虑到下行HARQ反馈与SRS的复用时,下行HARQ反馈所在的上行子帧的第2个时隙可以进一步考虑采用图18所示的结构,最后一个符号(符号5) 留给SRS使用,下行HARQ反馈仅使用前面5个DFT-S-OFDM符号。 [0122] When the system uses the CP extension, and considering the downlink HARQ feedback multiplexing SRS and uplink sub-frame where the downlink HARQ feedback in the second slot may further consider the structure shown in FIG. 18, the last symbol (numeral 5) using left SRS, downlink HARQ feedback using only the first five DFT-S-OFDM symbols. 前面5个DFT-S-OFDM符号中只有一个符号(符号2)用于传输RS,其余4个DFT-S-OFDM信号采用长度为4的OCC 序列进行时域扩展,可以复用传输4个UE的下行HARQ反馈。 5 in front of DFT-S-OFDM symbols, only a symbol (symbol 2) for transmission of the RS, the remaining four DFT-S-OFDM signal uses OCC sequences of length 4 time-domain spreading is performed, the transmission 4 can be multiplexed UE downlink HARQ feedback.

[0123] 所属领域技术人员根据复用方法易于想到,相应的解复用方法为:从具有6个DFT-S-OFDM符号的DFT-S-OFDM信号格式的前5个DFT-S-OFDM符号中的4个上提取下行HARQ反馈信息,其中RS在第3个DFT-S-OFDM符号上;并由所述DFT-S-OFDM信号格式的最后一个DFT-S-OFDM 符号SRS。 [0123] Those skilled in the art according to a multiplexing method is easy to occur, corresponding demultiplexing method is: the first 5 DFT-S-OFDM symbol DFT-S-OFDM signal format having six DFT-S-OFDM symbols 4 in the extracted downlink HARQ feedback information, wherein in the first three RS DFT-S-OFDM symbol; the last by a DFT-S-OFDM symbol SRS DFT-S-OFDM signal format.

[0127] 实施例5 : [0127] Example 5:

[0128] 在LTE Rel-8中,当下行HARQ反馈与SR需要在同一帧中进行传输时(此时无PUSCH),UE将采用SR所对应的PUCCH资源来传送下行HARQ的2比特ACK/NACK信息。 [0128] When in LTE Rel-8, SR downlink HARQ feedback in the same frame needs to be transmitted (in this case no PUSCH), UE will use the SR PUCCH resource corresponding to the downlink transmission of 2-bit HARQ the ACK / NACK information. 在LTE Rel-IO中,由于下行HARQ反馈比特数的增加,当下行HARQ反馈与SR需要在同一帧中进行传输时(此时无PUSCH),UE需要将下行HARQ反馈状态进行各种压缩操作,如空域捆绑,时域捆绑和跨CC捆绑等,之后产生两个比特,然后采用与LTE Rel-8相同的方法复用传输下行HARQ反馈与SR。 In LTE Rel-IO, a feedback due to the increase of the number of bits of the downlink HARQ, downlink HARQ feedback needs to transmit an SR in the same frame (in this case no PUSCH), UE needs to state the downlink HARQ feedback various compression operations, the spatial bundle, bundling and time-domain cross-CC bundling, after generating the two bits, then using the same method as multiplexed with LTE Rel-8 downlink with HARQ feedback transmission and SR. 在LTERel-IO中,以上方法比较适合处于功率受限(power limited)状态的UE,当UE不处在功率受限状态时,需要有方法能够将下行HARQ反馈信息与SR完整地传送给BS。 In LTERel-IO, the above method is suitable for the UE is power limited (power limited) state, when the UE is not in a power-limited state, need for a method of downlink HARQ feedback information can be completely transferred to the SR the BS.

[0129] 在LTE Rel-IO中,当UE需要传输的下行HARQ反馈比特数小于等于4时,UE的下行HARQ反馈传输方法为基于PUCCH格式Ib的信道选择,如果备选的PUCCH格式Ib的资源数量为4,该方法最大可以支持的下行HARQ反馈比特数为4 ;当UE需要传输的下行HARQ反馈比特数大于4时,UE的下行HARQ反馈传输方法为基于DFT-S-OFDM的信号,该方法最大可以支持的下行HARQ反馈比特数为11。 [0129] In LTE Rel-IO, when the UE requires several HARQ feedback bits for downlink transmission 4 or less, the downlink of the UE HARQ feedback transmission method of channel selection PUCCH format Ib based, if alternate PUCCH format Ib resources number 4, the number of downlink HARQ feedback bits maximum possible method supports is 4; and when the number of HARQ of downlink feedback bits UE needs to transmit is greater than 4, the downlink of the UE HARQ feedback transmission method based on DFT-S-OFDM signal, the the method of downlink HARQ feedback bits can support up to 11. 如果下行HARQ反馈的比特数是不固定的,而是可以按照所配置的CC的数量和针对每个CC配置的传输模式来半静态地确定,则当下行HARQ 反馈的比特数小于最大可以支持的下行HARQ反馈比特数(即4或11)时,UE始终可以将需要复用的1比特的SR作为一种特殊的ACK/NACK比特与下行HARQ反馈一起发送给BS。 If the number of bits of downlink HARQ feedback is not fixed, but may be configured according to the number of CC and to determine the semi-statically configured for each transmission mode CC, the downlink HARQ feedback is less than the maximum number of bits that can be supported when the number of downlink HARQ feedback (i.e., 4 or 11) bits, UE can always require a bit SR multiplexing as a special ACK / NACK feedback bits to the BS downlink HARQ together.

[0130] 为更好地将下行HARQ反馈与SR进行复用,本发明提出了一种将下行HARQ反馈与SR进行复用的方法,包括以下步骤:通过将所配置的备选的下行HARQ反馈对应的PUCCH资源的OCC序列变换为冗余序列,派生出附加备选PUCCH资源;从所配置的备选PUCCH资源和所派生的附加备选PUCCH资源中选择一个PUCCH资源;以及利用所选择的PUCCH资源来传输下行HARQ反馈;其特征在于,SR是通过下行HARQ反馈对应的PUCCH资源的OCC序列是否为冗余序列来指示的。 [0130] To better the downlink HARQ feedback and SR multiplexing, the present invention provides a downlink HARQ feedback and SR multiplexing method, comprising the steps of: alternatively configured by downlink HARQ feedback OCC sequence corresponding to the PUCCH resources transform redundant sequence, alternatively derive additional PUCCH resource; alternatively select a PUCCH resource from the configured PUCCH resources and PUCCH resources additional alternative derived; and using the selected PUCCH resources to transmit downlink HARQ feedback; wherein, if the SR is feedback OCC sequence corresponding to the PUCCH resource through the downlink HARQ redundancy sequence is indicated.

[0131] 下面以LTE Rel-IO中UE需要传输的下行HARQ反馈比特数小于等于4时的情况为例进行解释。 [0131] Next, the number of bits in the downlink HARQ feedback transmitted in LTE Rel-IO UE needs less in the case of 4:00 as an example will be explained. 此时UE的下行HARQ反馈传输方法为基于PUCCH格式Ib的信道选择。 At this time, a transmission method of downlink HARQ feedback channel selection of the UE is based on the PUCCH format Ib. 如图21 所示为系统采用常规CP时LTEPUCCH格式Ib发送结构图(系统采用扩展CP时,只要将阴影部分的RS减少一个OFDM符号即可)。 It is shown in Figure 21 (when the system uses the extended CP, as long as the shaded RS OFDM symbol to reduce a) LTEPUCCH transmission format Ib is a system configuration diagram of a conventional CP. 以下行HARQ反馈比特数为4为例,基于PUCCH格式Ib的信道选择方法具体是指这4比特由两部分组成:从所配置的备选PUCCH格式Ib资源(如4个)中选择一个用于传输下行HARQ反馈,这一自由度能够反映下行HARQ反馈比特中的1呢2(4) = 2个比特;在所选择的PUCCH格式Ib资源上传输QPSK符号构成另2个比特。 The following number of bits for the HARQ feedback line 4, for example, channel selection method based on the particular PUCCH format Ib refers to the 4-bit consists of two parts: selecting from the configured PUCCH format Ib resources (e.g., 4) for a transmitting downlink HARQ feedback, the degree of freedom it is possible to reflect the downlink 1 2 (4) = 2 bits in the HARQ feedback bits; the other symbols transmitted QPSK 2 bits on the PUCCH format Ib selected resource. 如图21所示,以系统采用常规CP为例,上述后2比特映射成的QPSK符号d分别通过OCC ;^歹Ij (si, s2, s3, s4) g'H^Si各·自才目歹[J (Const Amplitude Zero Auto—CoreIation, CAZAC)的循环移位(Cyclic Shift, CS)序列(长度为一个RB的OFDM子载波数,这里为12) 扩频后,放入一个上行子帧的两个时隙中(如图15对应d的位置)进行传输。 21, in an example system using a normal CP, the rear two bits mapped to QPSK symbols respectively d OCC; ^ bad Ij (si, s2, s3, s4) g'H ^ Si · Zicai each mesh bad [J (Const Amplitude Zero Auto-CoreIation, CAZAC) cyclic shift (cyclic shift, CS) sequence (RB length of a number of OFDM subcarriers, where 12) after the spreading, the uplink subframe into a two slots (the position corresponding to d in FIG. 15) for transmission. 这一结构的RS也通过另一OCC序列(sl',s2',s3')与CS序列扩频后放入如图15中阴影位置进行传输。 This structure also with RS CS sequence spread-spectrum transmission 15 into a position as shown in shadow through another OCC sequence (sl ', s2', s3 '). 在LTE系统中,PUCCH格式Ib的资源以OCC与CS序列的组合来进行区分和指示。 In the LTE system, PUCCH format Ib resources in combination with CS OCC sequences to distinguish and instructions.

[0132] 在LTE Rel-IO中,为了在基于PUCCH格式Ib的信道选择的方法中再加入一些自由度以指示额外的SR信息,可以利用对应于d的冗余的OCC序列[1 1 -1 _1](注意到LTE Rel-8 中已使用了[+1 +1 +1 +1], [+1-1 +1 _1],[+1 _1 _1 +1],而未使用该冗余序列)。 [0132] In LTE Rel-IO in the order based on the channel PUCCH format Ib is selected then add some additional degree of freedom to indicate the SR information may be utilized OCC sequences correspond to the redundancy of d [11-1 _1] (note in LTE Rel-8 have been used [+1 +1 +1 +1], [_1 + 1-1 + 1], [1 _1 _1 + +1], without using the redundancy sequence ). 系统采用扩展CP时,可以使用的对应于d的冗余的OCC序列为[1 -1 1 _1],[1 1 -1 -1] (注意到LTE Rel-8中扩展CP时已使用了[+1 +1 +1 +1],[+1 -I _1 +1],而未使用所述的两个冗余序列)。 The system uses the extended CP, corresponding to the redundant d OCC sequences may be used to [1-11 _1], [11-1-1] (note LTE Rel-8 has been used in the extended CP of [ +1 +1 +1 +1], [+ 1 -I _1 +1], without the use of the two redundant sequences). 利用这些冗余序列的一个具体例子是:当没有SR(即SR为负,negative) 与下行HARQ反馈需要复用时,下行HARQ反馈按照如上所述的基于PUCCH格式Ib的信道选择方法处理;当正的(positive) SR与下行HARQ反馈需要复用时,基于PUCCH格式Ib的信道选择方法所选出的format Ib资源的对应于d的OCC序列改用上述的冗余序列,即常规CP时选择[1 1 -1 -1],扩展CP时选择[1 -1 1 -1],[11 -1 -1]之一。 Using these redundant sequences is a specific example: when no SR (SR i.e., negative, negative) downlink HARQ feedback necessary in a multiplex, a downlink HARQ feedback channel selection method based on the PUCCH format Ib according to the process described above; when positive (positive) SR downlink HARQ feedback necessary in a multiplex, the format corresponding to resources Ib channel selection method based on the PUCCH format Ib is selected in d OCC sequences of the above-described switch redundant sequences, i.e., normal CP select [11-1-1], when the extended CP [1 -1 1 -1], one [11-1-1]. 此时对应于d的CS序列、对应于RS的OCC序列和CS序列均保持不变。 At this time, the d sequence corresponding to the CS, OCC sequences correspond to the RS and CS sequences remain unchanged. 相应地,解复用时,BS在解析可能存在SR的上行子帧的反馈信息时,如果发现PUCCH格式Ib资源的对应于d的OCC序列采用了上述冗余序列,则获知此次下行HARQ反馈中嵌入了positiveSR信息,否则认为当前无positive SR,艮口SR 是negative 的。 Accordingly, when demultiplexing, parsing the BS when there is feedback information may SR uplink subframe, and if found the corresponding resources in PUCCH format Ib d OCC sequences using redundant sequences described above, the downlink HARQ feedback is known embedded in positiveSR information, or that the current no positive SR, Burgundy mouth of SR is negative.

[0133] 以上方法从备选PUCCH格式Ib资源分配角度看可以等效地这样实现:BS—般分配4个备选PUCCH格式Ib资源给UE,考虑到额外需要传输1比特的SR,BS可以额外再分配4个备选PUCCH格式Ib资源给UE,这额外的4个PUCCH格式Ib资源是通过将原来的4 个PUCCH格式Ib资源的对应于d的OCC序列改变为冗余序列而派生出来的。 [0133] Alternatively, the above process from the perspective of the resource allocation PUCCH format Ib may be equivalently achieved see: BS- assigned as the PUCCH format Ib four possible resources to the UE, taking into account the need to transmit an additional bit SR, BS may additionally Alternatively redistribution 4 PUCCH format Ib resources to the UE, the extra 4 PUCCH format Ib resource by a corresponding four original resource in the PUCCH format Ib d OCC is changed to a redundant sequence derived sequence. 这样8个资源选其一可以反映3个比特,在该资源上传输QPSK构成另外2比特,一共是5比特,可以用于同时传输1比特的positive SR与4比特的下行HARQ反馈。 Thus eight resource may reflect one selected from 3 bits, 2 bits constitute additional QPSK transmission on the resource, a total of 5 bits, 1 bit may be used for simultaneous transmission of positive SR downlink HARQ 4-bit feedback. 需要注意的是,原来4个备选PUCCH格式Ib资源的对应于d的CS序列必须各不相同,这一点在基于PUCCH格式Ib的信道选择方法的备选资源分配时需要加以注意,考虑到这一备选资源的分配是半静态地实现的,故这一要求并不难实现。 Note that, the original corresponding to the four possible PUCCH format Ib CS resources in the sequence d must be different, this is the alternative resource allocation when the channel selection method based on PUCCH format Ib require attention, taking into account that an alternative allocation of resources to achieve a semi-static, it is not difficult to achieve this requirement.

[0134] 从上面的描述可以看出,信道选择主要是选择对应于d的PUCCH格式Ib资源,即对应于d的OCC和CS序列,而对应于RS的OCC和CS序列则可以根据对应于d的OCC和CS 序列以隐式的方式推断得到。 [0134] As can be seen from the above description, the channel selection mainly selected PUCCH format Ib resources correspond to d, i.e., corresponding to d in the OCC and CS sequences, and corresponding to the RS OCC and CS sequences it may correspond to d the OCC and CS sequences in an implicit manner extrapolated. 如果放松这一对对应于RS的OCC和CS序列的限制,允许UE 不但可以选择对应于d的OCC和CS序列,也可以选择对应于RS的OCC和CS序列,多出来的自由度可以用于指示SR,甚至其他信息,如额外的下行HARQ反馈信息等。 If the relaxation corresponding to the pair of RS and CS sequences OCC limits allows the UE may select only OCC corresponding to the d and CS sequences may be selected to correspond to the RS and CS OCC sequences, extra degrees of freedom can be used indicating the SR, or even additional information, such as additional downlink HARQ feedback information. 为此,本发明提出了一种将下行HARQ反馈与其他UCI进行复用的方法,包括以下步骤:将BS分配的备选PUCCH格式Ib资源的对应于数据的和对应于RS的OCC序列和CS序列进行组合,产生新的PUCCH格式Ib资源,其中新的PUCCH格式Ib资源按照信道选择方法可以获得的比原来更多的传输自由度;按照预先定义的映射关系将原始下行HARQ反馈与其他UCI映射为所述传输自由度。 To this end, the present invention provides a method of downlink HARQ feedback multiplexing the UCI with other, comprising the steps of: RS corresponding to the OCC sequences correspond Alternatively PUCCH format Ib resource allocation in a BS and CS data sequences are combined to produce a new PUCCH format Ib resources, wherein the new resource PUCCH format Ib may be obtained by the channel selection method more than the original transmission freedom; mapping relationship according to a predefined mapping the original downlink HARQ feedback and other UCI the degree of freedom for the transmission.

[0135] 上述方法的一个例子如下:假设BS给一个UE分配2个备选PUCCH格式Ib资源, 按LTE Re 1-8 的资源指示为(CSl,OCC1)和(CS2,0CC2),在CSl 与CS2,OCCl 与0CC2 都各不相同的前提下,考虑到RS选择,UE可以用于传送基于PUCCH格式Ib的资源可以表示为以下四个:(CS1, OCCl, CS1,,0CC1,),(CS1, OCCl, CS2,,0CC2,),(CS2, 0CC2, CS1,,0CC1,), (CS2,0CC2,CS2',0CC2'),其中每一个的前两个序列代表对应于d的OCC和CS序列,后两个序列代表对应于RS的OCC和CS序列,其中“'”代表该OCC或CS序列是从对应的不带“,,, 的OCC和CS序列以LTE Rel-8隐式的方式所确定的序列。从这个例子可以看出,UE可以传送的最大比特数从原来的3(2个资源对应于1比特,再加上QPSK的2比特)增加到了4 (4个资源对应于2比特,再加上QPSK的2比特),多出来的这1比特可以用于传输1比特的positive SR。当没有positive SR One example of [0135] the above-described method is as follows: Suppose the BS to the UE assigned a PUCCH format Ib alternatively two resources, a resource indication according to LTE Re 1-8 (CSl, OCC1) and (CS2,0CC2), and in CSl CS2, the OCCl 0CC2 are not the same with the premise of considering the selected RS, the UE can be based on a resource for transmitting the PUCCH format Ib may be expressed as the following four: (CS1, OCCl, CS1,, 0CC1,), (CS1 , OCCl, CS2,, 0CC2,), (CS2, 0CC2, CS1,, 0CC1,), (CS2,0CC2, CS2 ', 0CC2'), wherein the sequence represents the first two corresponding to each of the OCC and CS d sequence, the two sequences corresponding to representative of the OCC and CS RS sequence, where " '" represents the sequence from the OCC or the corresponding CS without ",,, the CS and OCC sequence LTE Rel-8 implicit manner the determined sequence can be seen from this example, the UE may transmit the maximum number of bits (corresponding to 1 bit 2 resources, plus a 2-bit QPSK) 3 increased from the original 4 (corresponding to four resource 2 bits, plus a QPSK 2 bits), extra bits may be used for this transmission 1 1 bit positive SR. when no positive SR ,UE 可以仅使用(CSl,OCCl,CS1,,0CC1,),(CS2, 0CC2, CS2,,0CC2,),依然兼容LTE Re 1-8。 , UE can use only (CSl, OCCl, CS1,, 0CC1,), (CS2, 0CC2, CS2,, 0CC2,), is still compatible with LTE Re 1-8.

[0136] 相应地,解复用时,BS需要针对每一种对应于数据的和对应于RS的OCC序列和CS 序列的组合所产生的PUCCH格式Ib资源进行检测(如进行能量检测,即先序列相关,然后检测能量是否大于某一个门限),然后根据检测出来的UE采用的PUCCH格式Ib及该格式中承载的QPSK符号,得到UE传送的所有比特;最后按照预先定义好的映射方法,从所述比特中分别取出下行HARQ反馈与其他UCI。 [0136] Accordingly, when demultiplexing, the BS needs to be detected (e.g., energy detection for PUCCH format Ib resource data corresponding to each combination of CS and OCC sequences corresponding to sequences of the generated RS, i.e., first serial correlation, detects whether energy and large than a certain threshold), then in accordance with the PUCCH format Ib detected by the UE, and setting the format QPSK symbols carried obtain all bits transmitted by the UE; and finally according to a fixed mapping method defined in advance, from the bits were taken downlink HARQ feedback and other UCI.

[0137] 需要指出的是,上述例子是在仅有2个备选PUCCH格式Ib资源前提下的,如果分配的备选PUCCH格式Ib资源增加,则增加的额外的比特数可以更多,具体方法与上述介绍相同,故不再赘述。 [0137] It should be noted that, in the above example are only two alternative resource premise PUCCH format Ib, alternatively PUCCH format Ib increases if resource allocation, the additional number of bits may be increased more specific method the same as described above, and therefore will not be repeated.

[0138] 另外需要指出的是,上述备选PUCCH格式Ib资源必须分配在同一个物理资源块(Physical Resource Block, PRB)之内。 [0138] Also to be noted that the above alternative PUCCH format Ib resources must be allocated in the same physical resource block (Physical Resource Block, PRB) of. [0139] 在LTE Rel-IO中当UE需要传输的下行HARQ反馈比特数大于4时,UE的下行HARQ 反馈传输方法为基于DFT-S-OFDM的信号,此时UE可以将1比特的SR BPSK调制后通过利用如图14〜图17中的同一时隙的两个RS的相位差传达给基站。 When [0139] In LTE Rel-IO when a UE needs to transmit in the downlink HARQ feedback bits is greater than 4, the UE downlink HARQ feedback transmission method based on DFT-S-OFDM signal, then the UE may be a 1-bit SR BPSK by using the same time slot as shown in FIG. 17 14~ phase modulated to convey two RS to the base station.

[0145] 实施例6〜8针对LTE Rel-IO上行控制信息传输方法设计中遇到的一些新问题, 提出了若干种与上行控制信道资源的分配有关的方法。 [0145] Example 6 ~ 8 LTE Rel-IO for uplink control information transmission method new problems encountered in the design proposed several methods to allocate uplink control channel resource associated.

[0146] 实施例6 : [0146] Example 6:

[0147] 如果UE的采用DFT-S-OFDM信号传输的下行HARQ反馈与采用PUCCH格式2格式传输的CSI反馈出现在同一个上行帧中时,UE可以选择丢弃CSI反馈,使用CSI反馈所对应的PUCCH格式2资源传送下行HARQ反馈。 [0147] If the UE uses downlink HARQ DFT-S-OFDM signal transmitted feedback CSI using 2 format for transmission of PUCCH format of feedback appears in the same uplink frame, UE can drop the CSI feedback using CSI feedback corresponding PUCCH format 2 downlink resource for transmitting the HARQ feedback. 基站可以预料到这一下行HARQ反馈与CSI反馈“碰撞”的情形,因此在有此碰撞发生的上行帧中,原本需要分配给该UE的DFT-S-OFDM资源可以转而分配给其他UE,以节省上行反馈的开销。 In this case the base station may expect downlink HARQ feedback and the feedback CSI "collision", and therefore the uplink frame has in this collision, otherwise need to be assigned DFT-S-OFDM resources of the UE may be assigned to another UE in turn, to save money uplink feedback. 故本发明提出了一种将基于DFT-S-OFDM 信号的下行HARQ反馈和基于PUCCH格式2的CSI进行复用的方法,包括以下步骤:根据预先定义的规则丢弃CSI信息;利用对应于CSI的PUCCH格式2资源发送下行HARQ反馈。 Therefore, the present invention proposes a downlink HARQ feedback DFT-S-OFDM signal and a method of multiplexing the PUCCH format 2 based CSI based, comprising the steps of: discarding CSI information according to predefined rules; CSI using the corresponding PUCCH format 2 transmit downlink HARQ feedback resource.

[0148] 以下进一步举例介绍上述方法。 [0148] The following Examples further describes the above-described method. 当下行HARQ反馈与CSI反馈碰撞时,也可以预先定义一些规则,使得一些重要的CSI反馈不会被丢弃,如RI反馈(某一种反馈类型)、下行PCC对应的CSI反馈(某一个下行CC对应的CSI反馈)、下行SCC对应的宽带CQI反馈(某一个/组CC对应的某一类CSI反馈)等。 When the next row to HARQ feedback CSI feedback collision may be pre-defined rules, a number of important CSI feedback that are not discarded, such as RI feedback (feedback type of a certain kind), corresponding to the PCC downlink CSI feedback (one downlink CC corresponding to the CSI feedback), SCC corresponding downlink wideband CQI feedback (one / CC group corresponding to a certain type of CSI feedback) or the like. 例如,可以定义规则,当UE的下行HARQ反馈与所有CC的RI反馈碰撞时,和/或下行HARQ反馈与下行PCC对应的所有CSI反馈碰撞时,和/或下行HARQ反馈与下行SCC所对应的宽带CQI反馈碰撞时,下行HARQ反馈压缩被为(例如)2比特,与基于PUCCH格式2的CSI反馈一起传输,如常规CP时利用PUCCH格式2格式的同一个时隙的两个RS的相位差,扩展CP时与CSI反馈联合编码等。 For example, all the CSI feedback collision rules can be defined, when the downlink HARQ the UE feedback all RI feedback collide with the CC and / or downlink HARQ feedback of the downlink corresponding to the PCC and / or downlink HARQ feedback downlink SCC corresponding wideband CQI feedback collision, to be compressed downlink HARQ feedback (e.g.) 2 bits transmitted with PUCCH format 2 based on the CSI feedback, such as using the same slot format of PUCCH format 2 when a normal CP retardation two RS when an extended CP with combined CSI feedback coding. 以上规则之外UE可以采用上一段所述的以PUCCH格式2资源代替DFT-S-OFDM资源来传输完整的下行HARQ反馈。 In addition to the above rules UE PUCCH format 2 may be used instead resources DFT-S-OFDM transmission resources to complete the downlink HARQ feedback employed in the above paragraph.

[0149] 由于该方案只是在下行HARQ反馈与CSI反馈碰撞时按照特定规则对CSI进行选择性复用而不改变下行HARQ反馈与CSI的具体复用方式,该方案所对应的解复用方法仍可以沿用现有技术的解复用方法或采用前述实施例中的解复用方法,或者不必采用解复用方法(对应于CSI全部被丢弃的情形)。 [0149] Since the program only in the downstream of the multiplexing CSI selectively according to a specific HARQ feedback and rules without changing the downlink CSI feedback collide with the CSI HARQ feedback DETAILED multiplexing mode, the program corresponding demultiplexing method is still It can still be used prior art demultiplexing method or using the demultiplexing method in the embodiment, or having to use demultiplexing method (corresponding to the case where all discarded CSI).

[0152] 实施例7 : [0152] Example 7:

[0153] 如图27所示,当所有下行资源赋予(downlink grant)都集中在下行PCC上时,继承自LTE Rel-8的隐式的资源分配方式可以用于解决基于PUCCH格式Ib的信道选择的备选资源分配问题。 When [0153] 27, when all of the downlink resources given (downlink grant) are concentrated on the PCC downlink, inherited from the LTE implicit resource allocation Rel-8 can be used to solve the channel selection based on the PUCCH format Ib, the alternative resource allocation problem. 如图27所示,由于下行PCC和下行SCC上的对应于某个UE的两个下行分配所对应的下行资源赋予都在下行PCC上,因此按照LTE Rel-8的隐式的资源分配方式可以得到两个PUCCH格式Ib资源,作为该UE传输下行HARQ反馈时的备选资源。 27, since the downlink corresponding to a downlink SCC PCC and two downlink assign a UE in the downlink resources corresponding to the downlink PCC are given, it is possible according to the implicit resource allocation in LTE Rel-8 PUCCH format Ib give two resources, the UE transmits a downlink HARQ feedback when the alternative resource. 考虑到基于两个PUCCH格式Ib资源的信道选择方法最大支持3个比特的下行HARQ反馈,因此需要制定规则来压缩UE的下行HARQ反馈的比特数以适应上述反馈限制。 Considering the two-channel selection method based on the PUCCH format Ib resources to support a maximum of three downlink HARQ feedback bits, it is necessary to compress the number of bits of rules downlink HARQ feedback from the UE to accommodate the feedback limit. 为此,本发明提出了一种用户设备的下行HARQ反馈信息的发送前处理方法,其特征在于:下行PCC上的下行分配对应的HARQ反馈信息不采用捆绑;下行SCC上的下行分配对应的HARQ反馈信息采用捆绑。 To this end, the present invention proposes a downlink A user equipment transmits HARQ feedback information before processing method, wherein: the downlink HARQ feedback information corresponding to allocation on the downlink PCC does not employ binding; downlink assignment on the corresponding downlink HARQ SCC feedback adopt binding.

[0154] 当UE对应于下行PCC和下行SCC的下行分配都是多码字传输模式(如MIMO传输模式)时,需要将下行SCC上的下行分配所对应的下行HARQ反馈比特进行诸如捆绑之类的压缩操作以产生1个比特。 [0154] When the UE corresponding to the downlink SCC PCC and downlink assignment is downlink multi-codeword transmission mode (e.g., MIMO transmission mode), requires a downlink assignment on a downlink SCC corresponding downlink HARQ feedback bits, such as a bundle or the like the compression operation to produce a bit. 该1比特与PCC上的2比特的ACK/NACK信息共同构成下行HARQ反馈。 The 1-bit and 2-bit NACK information on the ACK together constitute PCC / downlink HARQ feedback.

[0155] 应当注意的是,以上通过采用不同处理方式处理下行PCC和下行SCC上的下行分配所对应的下行HARQ反馈来适应下行HARQ反馈比特数限制的方法也可以适用于其他场景,而不仅仅局限于图27所示场景。 [0155] It should be noted that the above treatment process by using different downlink assignment on downlink, and downlink SCC PCC corresponding downlink HARQ feedback to adapt the method of downlink HARQ feedback bits limit may be applied to other scenarios, rather than limited to the scenario shown in FIG. 27.

[0158] 实施例8 : [0158] Example 8:

[0159] 如图四所示,当下行HARQ反馈比特数较多(如大于4个比特)时,PUCCH格式2 是一个比较理想的用来传输下行HARQ反馈的容器。 [0159] As shown, the number of downlink HARQ feedback bits when large (e.g., greater than 4 bits), the PUCCH format 2 is used to transmit four ideal container downlink HARQ feedback. 此时需要考虑当CSI反馈与下行HARQ 反馈同时出现时的处理,因为LTE Rel-8中由于考虑到上行覆盖等因素,不允许破坏上行单载波特性,因此也不允许有两个PUCCH格式2在同一个上行子帧上传。 Considerations in this CSI feedback processing when downlink HARQ feedback occur simultaneously, as LTE Rel-8 uplink coverage due consideration of such factors, not permitted to destroy the uplink single carrier characteristics, and therefore does not allow the two PUCCH format 2 Upload the same uplink subframe. LTE Rel-IO对上行单载波特性的要求有所放宽,至少在非功率受限场景下,如果同一个上行子帧中的两个PUCCH 格式2资源在同一个资源块(ResourceBlock,RB)或邻近RB中还是可以考虑一起传输的。 LTE Rel-IO claim uplink single carrier characteristics is relaxed, at least in the non-power limited scenario, if the same two uplink subframe resource PUCCH format 2 in the same resource block (ResourceBlock, RB) or adjacent RB transmission can still be considered together. 由于CSI反馈对应的PUCCH格式2资源是半静态配置给UE的,另外一个对应于下行HARQ 反馈的PUCCH格式2资源也可以考虑进行半静态分配,但是考虑到一个上行子帧中同时调度配置了多个下行CC的UE的数量是不多的,但是配置了多个下行CC的UE的总数可以有很多,上述对对应于下行HARQ反馈的PUCCH格式2资源进行半静态分配的方法会造成上行控制资源的浪费。 Since the PUCCH format 2 resource CSI feedback corresponding to semi-statically configured to the UE, another corresponding to PUCCH format 2 resources in the downlink HARQ feedback may be considered semi-static allocation, but considering the uplink subframe while the schedule is configured for multiple the number of downlink CC UE is not much, but the configuration of the total number of the plurality of downlink CC there can be many UE, the method described above PUCCH format 2 downlink resources corresponding to HARQ feedback semi-persistently allocated uplink control resources will result in waste. 为此,本发明提出了一种向用户设备分配PUCCH格式2资源的方法,包括以下步骤:为用户设备半静态地分配第一PUCCH格式2资源;为用户设备动态地分配第二PUCCH格式2资源;向用户设备发送指示第二PUCCH格式2资源与第一PUCCH格式2资源的相对位置的信息。 To this end, the present invention provides a method for the user equipment resources allocated PUCCH format 2, comprising the steps of: a user equipment a first semi-statically assigned resources PUCCH format 2; the second user device to dynamically allocate resources PUCCH format 2 ; transmitting information indicating that the second PUCCH format 2 resource to a user equipment and the relative position of the first resource format 2 PUCCH.

[0160] 以下通过举例说明上述方法。 [0160] The following method described above by way of illustration. 由于一个RB中按照LTE Rel-8的惯例一般可以支持6个PUCCH格式2资源,对应于CSI反馈的PUCCH格式2资源占用其中一个,对应于下行HARQ反馈的PUCCH格式2资源可以占用剩下的5个资源中的一个,这5个PUCCH格式2资源的位置可以通过与CSI反馈对应的PUCCH格式2资源之间的相对位置来表征,这个相对位置可以用一个offset来表示,offset取值1〜5可以分别代表这5个PUCCH格式2资源。 Since one RB conventionally generally LTE Rel-8 PUCCH format can support six resource 2 corresponding to the CSI feedback PUCCH format 2 wherein a footprint corresponding to the downlink HARQ feedback resource of PUCCH format 2 may occupy the remaining 5 a resource in which five resource location of PUCCH format 2 may be characterized by the relative position between the resources and PUCCH format 2 corresponding to the feedback CSI, the relative position may be represented by an offset, offset values ​​of ~ 5 this can represent five PUCCH format 2 resource, respectively.

[0161] 如果下行HARQ反馈资源是BS通过下行控制信息(DownlinkControl Information, DCI)通知给各个UE的,例如通过SCC上的下行资源赋予DCI中的冗余的2比特的发送功率控制(Transmit Power Control, TPC)域等,那么offset的值就需要有所限制。 [0161] If the BS downlink HARQ feedback resource is control information (DownlinkControl Information, DCI) notifies each UE through a downlink, for example, by imparting redundancy in the DCI SCC downlink resources on the 2-bit transmit power control (Transmit Power Control , TPC) fields, etc., then the value of the offset would need to be restricted. 比如考虑到2比特的限制,offset仅能取值1〜4,指示上述5个PUCCH格式2资源中的4个。 Consider, for example the 2-bit limit, offset values ​​only ~ 4, 5 instructs the PUCCH format 2 resources 4.

[0162] 可以预见,对于某一个UE来说,除了与其CSI反馈相对应的PUCCH格式2资源,在同一个RB中,不一定存在空闲PUCCH格式2资源,因为有可能该RB中的所有PUCCH格式2 资源目前都被占用,或者由于off set自身的比特位长的限制无法指示到某个空闲的PUCCH 格式2资源。 [0162] It is foreseeable that for a certain UE, in addition to their corresponding CSI feedback resource PUCCH format 2, in the same RB, the PUCCH format 2 is not necessarily there is a free resource, since it is possible for all of the PUCCH formats of RB 2 resources are currently being used, or due to off set bit longer limit itself fails to indicate to an idle PUCCH format 2 resource. 此时有以下一些解决方法。 There are some solutions at this time.

[0163] BS拥有所有PUCCH格式2资源的占用信息,故BS可以选择在上述情况下避免调度该UE,或对其调度作一些限制,以避免使用基于PUCCH格式2资源的下行HARQ反馈;BS也可以选择通知UE,或者UE按照某些规则自行决定,在上述情况下丢弃CSI而利用CSI对应的PUCCH格式2资源传送下行HARQ反馈;或者UE将下行HARQ反馈经过捆绑压缩后与CSI 反馈一起按照LTE Rel-8的方式传送;或者UE使用同一个RB中的那些系统因考虑到时延扩展而留空不用的PUCCH格式2资源。 [0163] BS has occupied resources All PUCCH formats 2, so that the BS may choose to avoid scheduling the UE, or to some limitations to its schedule to avoid the use of feedback based on the downlink resource of the HARQ PUCCH format 2 in the above case; BS also may choose to notify UE, or the UE according to certain rules to decide, in such a case to drop the CSI and CSI using PUCCH format 2 corresponding to downlink resource for transmitting HARQ feedback; or the UE after the downlink HARQ feedback CSI feedback bundled together in compression and LTE rel-8 transmission manner; or UE that use the same system in one RB in consideration of the blank and without delay spread PUCCH format 2 resource.

[0164] 如图30,BS还可以在每一个为CSI反馈而预留的PUCCH格式2资源块中预留一个PUCCH格式2资源用作下行HARQ反馈资源。 [0164] As shown in FIG 30, BS may also be one of CSI feedback in each reserved PUCCH format reserve a resource PUCCH format 2 is used as the second resource block of downlink HARQ feedback resource. 如图30所示,8个RB分成两组,每组中的每一个RB均半静态地预留一个PUCCH格式2资源用以传输下行HARQ反馈,剩余的用于半静态地分配给各个UE作CSI反馈。 30, 8 RB into two groups each of RB are semi-statically reserve a resource for transmission of PUCCH format 2 downlink HARQ feedback for the remaining semi-statically assigned for each UE CSI feedback. 此时上述offset可以重新定义为用以指示某一组预留PUCCH格式2资源中,UE占用的哪一个来传输下行HARQ反馈。 At this time, the aforementioned offset can be redefined to indicate a set of resources reserved for PUCCH format 2, which occupies a UE to transmit downlink HARQ feedback. UE—般事先半静态地被配置为使用某一组(每组中有4个PUCCH格式2资源)的PUCCH格式2资源用以传输下行HARQ反馈,而offset则通过DCI向UE通知该组中具体哪一个资源被该UE使用。 UE- advance as semi-statically configured to use a group (each group has four resource PUCCH format 2) PUCCH format 2 downlink resource for transmitting the HARQ feedback, and the set offset is notified to the UE through DCI particular which resources are used to the UE. 当UE的下行HARQ反馈与CSI反馈不碰撞时,UE利用上述资源传输下行HARQ反馈。 When the UE downlink HARQ feedback colliding with CSI feedback, UE using the downlink HARQ feedback transmission resources. 当UE的下行HARQ反馈与CSI反馈发生碰撞时,UE将忽略offset而利用与所配置的CSI反馈资源处于同一个RB中的那个预留的PUCCH格式2资源来传输下行HARQ反馈。 When the downlink HARQ feedback from the UE to a CSI feedback collide, the UE ignores offset utilize CSI feedback resource in the same configuration with that one RB PUCCH format 2 resource reservation to transmit downlink HARQ feedback.

[0165] 应当注意的是,本实施例中讨论的是下行HARQ反馈所对应的资源的分配方法, 这一资源分配方法同样适用于其他需要利用到两个PUCCH格式2资源的场景,如PUCCH格式2的SORTD发送方式下的第二个PUCCH格式2资源的分配。 [0165] It should be noted that the embodiment discussed in the present embodiment is a method for allocating resources in the downlink HARQ feedback corresponding to this resource allocation method is equally applicable to other scenarios need to use two PUCCH format 2 to the resources, such as PUCCH Format the second PUCCH format 2 resource allocation under SORTD 2 transmission scheme.

[0168] 实施例9 : [0168] Example 9:

[0169] 在之前的实施例中,多有讨论到当UE的下行HARQ反馈与CSI反馈碰撞时,下行HARQ状态通过各种捆绑处理压缩为2比特反馈信息,然后嵌入到CSI反馈所对应的PUCCH 格式2格式的同一时隙的两个RS的相位信息中去,由此可以同时将下行HARQ反馈(不完整)和CSI反馈同时传送给BS。 Embodiment [0169] In the previous embodiment, discussed more than a when the UE a downlink HARQ feedback collides with CSI feedback, downlink HARQ state compressed to 2-bit feedback information is processed by various bundling, then fitted into the corresponding CSI feedback PUCCH two RS phase information of the same time slot format to the second format, whereby simultaneously the downlink HARQ feedback (incomplete) and CSI feedback to the BS at the same time.

[0170] 下行HARQ状态与上述2比特反馈信息(b(0),b(l))的映射如表1所示。 [0170] state of the two downlink HARQ feedback information bits (b (0), b (l)) mapping as shown in Table 1. 其意义是UE检查捆绑窗口(bundling window)内的各个HARQ进程的状态,如果所有HARQ状态都是NACK或者UE通过下行分配指示(Downlink Assignment Index, DAI)发现至少有一个非连续发送(Discontinuous Transmission, DTX)存在,则将下行HARQ状态映射为(0,0);否则计算捆绑窗口内的HARQ状态为ACK的数量,在表1中选择对应的2比特反馈信息。 In the sense that the state of each HARQ process in the UE checks bundling window (bundling window), if the states are all HARQ NACK or the UE through a downlink assignment index (Downlink Assignment Index, DAI) was found with at least one discontinuous transmission (Discontinuous Transmission, DTX) is present, HARQ status map is (0,0) then the downlink; otherwise calculating the bundling window state quantity HARQ ACK selects a corresponding in table 12-bit feedback information.

[0174] 表1的作用是:当DAI不存在时,表1能够协助BS判断在整个捆绑窗口中是否存在因下行资源赋予信息丢失造成的DTX ;当DAI存在时,表1能够协助BS判断整个捆绑窗口中的最后一个下行资源赋予信息是否丢失。 Effect [0174] Table 1 are: When DAI is not present, Table 1 can help BS determines whether there is a DTX due to downlink resource related information loss caused throughout the bundling window; when DAI is present, in Table 1 can help BS determines the entire bundling window last downlink resource related information is lost. 尽管表1指出了捆绑窗口内的ACK的数量, 但是当该数量与BS调度给UE的下行分配数量不符时,BS无从判断哪一些下行分配对应的HARQ状态是ACK,即正确接收了,哪些没有正确接收,因此只能全部重传,造成吞吐量的损失。 While Table 1 indicates the number of ACK bundling within the window, but when the number of discrepancies downlink allocation of the number of BS schedules to the UE, the BS can not judge which of HARQ state of the downlink assignment corresponds to ACK, i.e. correctly received, which is not received correctly, it can only all retransmissions, resulting in loss of throughput. 为此,本发明提出了一种用户设备端的下行HARQ反馈状态捆绑映射方法,包括:检查捆绑窗口内连续为ACK的下行HARQ反馈状态的数量;基于预定的映射关系,根据所检查的数量,确定下行HARQ反馈状态捆绑映射的结果,所述预定的映射关系定义了下行HARQ反馈状态捆绑映射的结果和捆绑窗口内连续ACK的数量,使得下行HARQ反馈状态捆绑映射的结果能够反映捆绑窗口内连续ACK的数量。 To this end, the present invention provides a user terminal apparatus bundled downlink HARQ feedback state mapping method, comprising: a continuous number of downlink HARQ ACK feedback bundling window state within the examination; based on a predetermined mapping relationship, depending on the number of checks to determine results bundled downlink HARQ feedback state map, said predetermined relationship defines the mapping result within the bundling window and feedback of downlink HARQ state bundled ACK number of continuous mapping, a downlink HARQ feedback so that the result can reflect the state of continuous bundled ACK mapped within the bundling window quantity.

[0178] 表2的意义是UE检查捆绑窗口内的各个HARQ进程的状态,如果所有HARQ状态都是NACK或者UE通过下行分配指示DAI发现至少有一个非连续发送DTX存在,则将下行HARQ状态映射为(0,0);否则计算捆绑窗口内从第一个下行分配对应的HARQ状态开始连续为ACK的HARQ状态的数量,在表2中选择对应的2比特反馈信息。 [0178] Table 2 is the meaning of each HARQ process state in the UE checks the bundling window, if all the HARQ NACK or states are found to have at least DAI UE indicates a presence of discontinuous transmission DTX, then the downlink HARQ state mapping downlink assignment (0,0); otherwise, calculated from the first HARQ state corresponding to a downlink assignment within a bundling window to the start of a discrete number of HARQ ACK state, selecting the corresponding 2-bit feedback information in table 2.

[0179] 表2的作用是BS根据2比特反馈信息可以部分获知哪些下行分配正确接收,能够在一定程度上提高下行吞吐量。 [0179] Table 2 is the role of the BS can know which part of the downlink assignment in accordance with 2-bit correctly received feedback information, downlink throughput can be improved to some extent.

[0180] 表2的问题在于:由于反馈信息比特位长(2)的限制,不同连续ACK数量可能对应于相同的反馈信息,BS无法明了连续ACK的数量到底是多少。 [0180] Table 2 is that the problem: Since the feedback information bit length (2) limitations, a different number of consecutive ACK feedback may correspond to the same information, the number of consecutive ACK BS in the end not clear how much. 一个简单的增强方法如表3 所示: A simple method of enhancement as shown in Table 3:

[0181] 表3吞吐量增强的下行HARQ反馈状态捆绑映射方案2 [0181] Table 3 to enhance throughput of downlink HARQ feedback is bundled state mapping scheme 2

[0182] [0182]

捆绑窗口内的连续的ACK的数量 b(0),b(l)0或UE检测到DTX 0,01 1,1 Continuous bundled ACK within the window number b (0), b (l) 0 or UE detects DTX 0,01 1,1

Figure CN102378385AD00251

[0183] 表3的好处是没有疑义,当捆绑窗口内的连续ACK的数量大于等于3时,一律反馈(0,1), BS至少可以没有疑义地获知前三个下行分配UE是正确接收的。 [0183] Table 3 that there is no benefit of doubt, when the number of consecutive ACK within the bundling window is greater than equal to 3, all feedback (0,1), before the three downlink assignment UE BS may no doubt be correctly received is informed of at least .

[0184] 应该注意的是,表2和表3以下行DCI中存在DAI为前提。 [0184] It should be noted that in Tables 2 and the presence of the following lines in the DCI DAI 3 premise.
