Description

混合自动重传请求处理方法 Hybrid automatic retransmission request processing method

技术领域 FIELD

本发明涉及宽带码分多址(WCDMA, Wideband Code Division MultipleAccess)技术领域,尤其是涉及一种混合自动重传请求处理方法。 The present invention relates to wideband code division multiple access (WCDMA, Wideband Code Division MultipleAccess) technologies, and particularly relates to a hybrid automatic repeat request processing method.

背景技术 Background technique

在宽带码分多址(WCDMA, Wideband Code Division Multiple Access)系统中,高速上行链路分组接入(HSUPA, High Speed Uplink Packet Access)技术是WCDMA R6版本中最新引入的一种上行增强技术,其主要包括如下几个技术点: Wideband code division multiple access (WCDMA, Wideband Code Division Multiple Access) systems, High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology is a technology WCDMA R6 uplink enhanced version recently introduced, which The main technical points include the following:

1) NodeB控制的调度技术; 1) Control NodeB scheduling technique;

2) 混合自动重传请求(HARQ, Hybrid Automatic Repeat request)的带软 2) a hybrid automatic retransmission with soft request (HARQ, Hybrid Automatic Repeat request) of

合并技术; The combined technology;

3) 更短的'专输时间间隔(TTI, transmission Time interval)技术。 3) shorter 'dedicated transmission time interval (TTI, transmission Time interval) technology.

其中,上述HARQ合并技术主要用于增强型专用信道(E-DCH, EnhancedDedicated Channel)的物理层快速重传处理,通过初传和重传之间的软合并来提高E-DCH物:蓬层的译码性能。 Wherein said HARQ combining techniques primarily for enhanced dedicated channel (E-DCH, EnhancedDedicated Channel) physical layer fast retransmission process to improve purified by E-DCH soft combining between initial transmission and retransmission: Peng layer decoding performance. 其中E-DCH是HSUPA技术在上行引入的一种增强型专用信道。 Wherein the E-DCH is an enhanced dedicated channel uplink HSUPA technology introduced.

请参照图1,该图是现有技术中在UE侧的E-DCH物理层上进行HARQ处理的处理过程示意图,其主要处理过程如下: Referring to FIG 1, which is a process of the prior art perform the HARQ processing on the physical layer of the UE E-DCH is a schematic side, the main process is as follows:

E-DCH信道编码后的输出Nej经过bit分离处理(bit separation)分离为系统位(Systematic bits )、校验位1 (Parity 1 bits)和校验位2 (Parity 2 bits)三个序列; Output Nej E-DCH after channel coding bit after separation (Separation bit) isolated as a system bit (Systematic bits), parity bit 1 (Parity 1 bits) sequence and three parity bit 2 (Parity 2 bits);

将该三个序列分别进行速率匹配(RM, Rate Matching)处理,将速率匹配处理后的三个序列进行bit合路处理(bit collection ),并将bit合路处理后的比特映射到E-DCH专用物理数据信道(E-DPDCH, E-DCH Dedicated PhysicalData Channel)中进行传输。 The three sequences are rate matching (RM, Rate Matching) treatment, the three sequence after rate matching processing bit processing combiner (bit Collection), and the processed bits are mapped to the bit E-DCH combiners dedicated physical data channel (E-DPDCH, E-DCH dedicated PhysicalData channel) for transmission.

其中速率匹配处理的主要作用是将速率匹配前的可变比特数匹配到一个固定速率的物理信道上进行传输。 Wherein the rate matching main function is to match the number of bits before rate matching variable to a fixed rate physical channel for transmission. 其中才艮据速率匹配前的比特数和速率匹配后的比特数关系,可以分为重复速率匹配处理和打孔速率匹配处理两种方式,若当速率匹配前的比特数小于速率匹配后的比特数时,要采用重复速率匹配方式进行处理,即将速率匹配前的序列某些位置的比特进行重复发送;否则采用打孔速率匹配处理方式进行处理,即将速率匹配前的序列某些位置的比特不进行发送。 Wherein only Gen-correlation data bits after the number of bits before rate matching and rate matching, can be divided into repeating and puncturing rate matching processing rate matching process in two ways, if the number of bits after rate matching is smaller than the pre-rate matching bit when the number of repetition rate matching manner to be used for processing, some of the bit positions immediately before the sequence is repeated to match the transmission rate; otherwise, puncturing using the rate matching processing mode for processing the bit sequence at certain positions immediately before the rate matching is not sending.

目前协议中规定无线接入网(RAN, Radio Access Network )侧通过将HARQ合并处理信息承载在RAN侧和用户终端(UE, User Equipment)侧进行交互的无线资源控制(RRC, Radio Resource Control)信令中,并通过NodeB透传给UE,然后UE基于接收到的HARQ合并处理信息进行HARQ合并处理。 Currently predetermined protocol radio access network (RAN, Radio Access Network) side by HARQ combining process information carrier (RRC, Radio Resource Control) RRC letter RAN side and the user terminal (UE, User Equipment) side to interact in order, through the NodeB and UE pass through, the UE then merge processing information based on the received HARQ process for the HARQ combining.

但是Node:3在将RAN下发的HARQ合并处理信息透传给UE的过程中,不会对HARQ合并处理信息进行任何处理,只M到透传的作用,因此对于NodeB而言是不了解RAN下发给UE的HARQ合并处理信息的,这样就^it成NodeB和UB可能基于不同的HARQ合并处理信息进行HARQ处理,导致NodeB无法正确的进行HARQ合并处理。 However, Node: 3 RAN issued during the HARQ combining process information transparently to the UE, HARQ combining process will not process any information, only the role of M to pass through, so for purposes NodeB RAN is unaware next to the UE HARQ combining process information, so ^ it to NodeB and UB may be based on different HARQ combining process information HARQ processing, resulting in NodeB can not be correct HARQ combining process.

上述方法的主要实现原理即是:由NodeB来决定HARQ合并方式;NodeB 在处理无线链路建立请求信令、无线链路同步重配准备信令或无线链路异步重配请求信令过程中,根据自身的实际处理能力、资源状况、或业务类型等来选择相应的HARQ合并方式,并将选择的HARQ合并方式对应的HARQ合并方式信息通过承载在无线链路建立请求响应信令、无线链路同步重配准备响应信令或无线链路异步重配请求响应信令中上报给RNC; RNC通过将从NodeB处接收到的HARQ合并方式信息承载在RRC信令中下发给UE, UE再根据RNC 下发的HARQ合并方式信息进行对应的HARQ处理,从而实现了NodeB和UE进行一致性的HARQ处理的目的。 The main implementation principle of the method described above that is: the NodeB determines the HARQ combined manner; NodeB handling radio link setup request signaling, synchronization radio link reconfiguration preparation signaling or an asynchronous radio link reconfiguration request signaling process. according to their actual processing capability, the resource condition or service type of HARQ combiner to select the appropriate mode, and HARQ combining scheme information corresponding to the selected HARQ combiner by way of a radio link bearer establishment request response signaling, the radio link synchronous reconfiguration response signaling to prepare an asynchronous radio link reconfiguration or request response signaling is reported to the RNC; merge the HARQ mode information received by the RNC from the NodeB to the UE bearer in the RRC signaling, and then according to the UE RNC issued HARQ combining scheme information corresponding to the HARQ process, thus achieving the purpose of the NodeB and UE HARQ process consistency.

请参照图3.该图是本发明提出的第二种混合自动重传请求处理方法的主要实现原理流程图,其主要实现过程包括: Referring to Figure 3 which is a flowchart showing a main realization principle of the present invention, the second mixing proposed automatic repeat request processing method, the main implementation process comprising:

步骤S100, NodeB确定HARQ合并能力;其中NodeB可以将自身的HARQ 合并能力作为确定的HARQ合并能力,HARQ合并能力主要包括如下三种情况: Step S100, NodeB determines HARQ combining ability; NodeB may itself which HARQ combining ability of the ability to determine the HARQ combined, HARQ combining ability include the following three conditions:

蔡斯合并和增量冗余合并(both Chase Combining and Incremental redundancy Combining )。 Chase combining and incremental redundancy merge (both Chase Combining and Incremental redundancy Combining).

步骤S200, NodeB将上述确定的HARQ合并能力上报给RNC; 其中NodeB可以选择在接收到RNC下发的审计请求信令(AUDIT REQUEST)后,通过将自身确定的HARQ合并能力承载在审计响应信令(AUDIT RESPONSE)中上报给RNC;也可以选择将自身确定的HARQ合并能力承载在资源状态指示信令(RESOURCE STATUS INDICATION)中主动上报给RNC。 Step S200, NodeB determines the capability of the HARQ combiner reported to the RNC; NodeB may choose where to the RNC after receiving the issued audit request signaling (AUDIT REQUEST), HARQ combined capacity determined by the carrier itself in the audit response signaling (AUDIT RESPONSE) to be reported to the RNC; HARQ combiner may be selected to determine their ability to bearer resource status indication signaling (rESOURCE sTATUS iNDICATION) initiative to report to the RNC.

步骤S300, RNC根据NodeB上报的HARQ合并能力,选择对应的HARQ 合并方式信息分别下发给NodeB和UE; Step S300, RNC according to the HARQ combined capacity NodeB reported, HARQ combining mode selection information corresponding to the respective NodeB and the UE sent;

其中RNC可以将HARQ合并方式信息承载在无线链路建立请求信令、无线链路同步重配准备信令或无线链路异步重配请求信令中下发给NodeB,并将HARQ合并方式信息承载在无线资源控制信令(RRC)中下发给UE。 Wherein the RNC HARQ combining scheme information may be carried in the radio link setup request signaling, synchronization radio link reconfiguration preparation signaling or an asynchronous radio link reconfiguration request signaling sent at the NodeB, and the HARQ mode information merge carrier to the UE under the radio resource control signaling (RRC) in.

步骤S400, NodeB根据RNC下发的HARQ合并方式信息,进行对应的HARQ合并处理,并UE根据RNC下发的HARQ合并方式信息,进行对应的HARQ处理,从而实现了UE和NodeB基于相同的HARQ合并处理信息进行HARQ处理的目的,使得NodeB能够正确执行HARQ合并处理。 Step S400, NodeB according merger HARQ information issued by the RNC, for the corresponding HARQ combining process, and UE according to the merger HARQ information issued by the RNC, for the corresponding HARQ process, thereby realizing the UE and NodeB combined based on the same HARQ HARQ processing object information processing can be performed such that the NodeB HARQ combining process correctly.

上述方法的主要实现原理即是:NodeB确定HARQ合并能力,并在接收到RNC下发的审计请求(AUDIT REQUEST)信令后,通过审计响应(AUDIT RESPONSE )信令将E-DCH HARQ合并能力通知给RNC,或者NodeB通过资源状态指示(RESOURCE STATUS INDICATION)信令主动将E-DCH HARQ合并能力通知给RNC; The main implementation principle of the method described above that is: NodeB determines HARQ combining ability, and the RNC receives the audit request issued after (AUDIT REQUEST) signaling, signaling E-DCH HARQ combined by audit capability notification response (AUDIT RESPONSE) to the RNC, NodeB or indication (rESOURCE sTATUS iNDICATION) active notification signaling E-DCH HARQ combined capacity to the RNC through the resource status;

RNC在接收到NodeB上报的E-DCH HARQ合并能力后,选择对应的E-DCH HARQ合并方式,并将选择的E-DCH HARQ合并方式信息分别下发给NodeB和UE; RNC after receiving E-DCH HARQ combined NodeB capability reported by the selected E-DCH HARQ combined mode corresponding to, and the selected E-DCH HARQ combined mode information are sent to the NodeB and the UE;

NodeB根据RNC下发的E-DCH HARQ合并方式信息,执行对应的HARQ 合并处理,并UE根据RNC下发的E-DCH HARQ合并方式信息,执行对应的HARQ处理。 NodeB according to the HARQ mode information merge E-DCH issued by the RNC, performing the processing corresponding HARQ combining, and UE according to the HARQ mode information merge E-DCH issued by the RNC, performing the corresponding HARQ process.

其中HARQ合并能力主要包括如下三种情况: Wherein the HARQ combined capabilities include the following three conditions:

蔡其斤合并禾3增量冗余合并(both Chase Combining and Incremental redundancy Combining );即E-DCH HARQ合并能力信息具体定义如下表所示: Cai 3 pounds combined Wo combined incremental redundancy (both Chase Combining and Incremental redundancy Combining); i.e., E-DCH HARQ combined capability information of a specific definition is as follows:

<table>table see original document page 11</column></row> <table>由于HARQ处理过程是将信道编码器输出的比特数目映射匹配到E-DPDCH上的物理信道比特数目上,从而HARQ合并处理过程受到冗余版本(RV, Redunckncy Version)参数的控制,其中RV参数的定义如下表所示: 表l: RV参数定义表 <Table> table see original document page 11 </ column> </ row> <table> Since the HARQ process is the number of bits of the channel encoder output map matched to the number of physical channel bits on the E-DPDCH, so that HARQ combining process by redundancy version (RV, Redunckncy version) control parameters, wherein the RV parameter is defined as follows: table L: RV parameter definition table

<table>table see original document page 11</column></row> <table> <Table> table see original document page 11 </ column> </ row> <table>

其中信道编码器输出的比特经bit分离处理后,分离出的系统位和校验位会共享E-DPDCH上的物理信道比特数目,表1中s参数用来标识是系统位优先占用E-DPDCH上的物理信道比特数目,还是校验位优先占用E-DPDCH上的物理信道比特数目,因此会影响速率匹配后系统位和校验位在E-DPDCH上的物理信道中所占用的比特数目。 Wherein the bit by bit separation channel encoder output, separated systematic bits and parity bits share number of physical channel bits on the E-DPDCH, Table 1 s parameter is used to identify the system bit preemption E-DPDCH on the number of physical channel bits, or check bits preemption number of physical channel bits on the E-DPDCH, thus affecting the number of bits after rate matching system and check bits on a physical channel E-DPDCH is occupied. 表1中如果s为1表示系统位优先占用E-DPDCH上的物理信道比特数目,速率匹配过程会优先满足系统位,系统位会分到更多的E-DPDCH上的物理信道比特数目;如果s为0则表示校验位优先占用E-DPDCH上的物理信道比特数目,速率匹配过程会优先满足校验位, 校验位会分到更多的E-DPDCH上的物理信道比特数。 Table 1 If s is 1 shows a system bit preemption number of physical channel bits on the E-DPDCH, the rate matching process is preferentially satisfied systematic bits, systematic bits can be assigned to track the number of bits of the physical channel on more E-DPDCH; if s is 0, said parity bit preemption number of physical channel bits on the E-DPDCH, the rate matching process to meet the priority check bits, parity bit is assigned to the number of physical channel bits on more E-DPDCH. 其中表1中的r参数用来决定重复速率匹配处理或打孔速率匹配处理的起始比特位置。 Wherein r in Table 1 is used to determine the parameters repetition rate matching puncturing or rate matching process of the position of the start bit.

此外由上述表1可见,E-DCH的RV索引值(RV Index)和参数s/r值存在映射关系,其中RV Index是根据重传序列号(RSN, Retransmission sequencenumber )和系统位速率匹配长度/物理信道比特数[Nsys/(Ne,dataj)]来确定的。 In addition there is a mapping relation from the above Table 1 shows, E-DCH RV of the index value (RV Index) and a parameter s / r value, where RV Index is and the system bit rate matching according to the retransmission sequence number (RSN, Retransmission sequencenumber) length / the number of physical channel bits [Nsys / (Ne, dataj)] determined. 而且,当RSN^3时,还要依靠TTIN (TTI号)(注:即RSN=0, 1, 2时,根据RSN值和使用的码速率来确定RV Index参数值;当RSN=3时,RV Index 参数值除根据RSN值和使用的码速率来确定之外,同时还与TTIN有关,具体如下表2所示)。 Further, when the RSN ^ 3 time, but also rely TTIN (TTI number) (Note: the RSN = 0, 1, 2, the parameter value is determined according to RV Index RSN value and the code rate used; when RSN = 3, RV Index parameter values ​​except RSN value is determined according to a code rate and use, and also related TTIN, as shown below in table 2).

<table>table see original document page 12</column></row> <table>表2中,对于10ms的TTI而言,其TTI号TTIN等于连接帧号(CFN, Connect Frame Number); 对于2ms的TTI而言: TTIN = 5 x CFN+2ms子帧号 <Table> table see original document page 12 </ column> </ row> <table> Table 2, for the 10ms TTI, its TTI number is equal to TTIN connection frame number (CFN, Connect Frame Number); for the 2ms For TTI: TTIN = 5 x CFN + 2ms sub-frame number

此处子帧号为一个给定CFN中的5个TTI的序号,第1个TTI子帧号为0, 第5个TTI的子帧号为4。 Here the sub-frame number CFN is a number in a given TTI 5, 1 TTI first subframe number is 0, the 5th TTI sub-frame number 4.

表2中的NARQ表示混合自动重传请求HARQ的进程数。 Table 2 NARQ represents the number of hybrid automatic retransmission request HARQ process of.

分別如下: They are as follows:

E-DCH RV Index恒为0时,采取蔡斯合并(Chase Combining)方式进行HARQ合并处理; E-DCH RV Index 0 is a constant, taken combined Chase (Chase Combining) mode for HARQ combining process;

E-DCH RV Index会随RSN (重传序列号,初传为0,每重传一次加1,最大限制为3)发生变化时,采取增量冗余合并(Incremental redundancy Combining)方式进4亍HARQ合并处理。 E-DCH RV Index will vary with the RSN (retransmission sequence number, 0 is the initial transmission, retransmission each time plus 1, is limited to a maximum 3) changes, taken combined incremental redundancy (Incremental redundancy Combining) mode into right foot 4 HARQ combining process.

根据上述,因此本发明上述提出的两种HARQ处理方法中,如果HARQ 合并方式信息中指示E-DCH RV Index恒为0时,NodeB对应采用蔡斯合并(Chase Combimng)方式进行HARQ合并处理;如果HARQ合并方式信息中指示E-DCH RV Index会随RSN发生变化时,NodeB对应采用增量冗余合并(Incremental redundancy Combining )方式进行HARQ合并处理。 According to the above, and therefore two kinds of the above-described HARQ processing method of the present invention proposed, if the HARQ combining scheme information indicating the E-DCH RV Index constant at 0, NodeB corresponding to the combined use of Chase (Chase Combimng) manner HARQ combined treatment; if when the HARQ combining mode information indicating E-DCH RV Index vary with RSN, NodeB corresponding to the combined use of incremental redundancy (incremental redundancy Combining) mode for HARQ combining process.
