一种混合自动重传请求处理方法A hybrid automatic repeat request processing method

技术领域technical field

本发明涉及无线通信领域，尤其涉及宽带码分多址(Wide-band CodeDivision Multiple Address)系统中采用高速上行链路分组接入(HSUPA，HighSpeed Uplink PacketAccess)技术时，一种混合自动重传请求(HARQ，HybridAutomatic Repeat request)处理方法。The present invention relates to the field of wireless communication, in particular to a hybrid automatic retransmission request (HSUPA) when high-speed uplink packet access (HSUPA, HighSpeed Uplink PacketAccess) technology is adopted in a Wide-band Code Division Multiple Access (Wide-band CodeDivision Multiple Address) system HARQ, HybridAutomatic Repeat request) processing method.

背景技术Background technique

在WCDMA系统中，HSUPA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：In the WCDMA system, HSUPA technology is the latest uplink enhancement technology introduced in the WCDMA R6 version, which mainly includes the following technical points:

1)基站(NodeB)控制的调度技术；1) Scheduling technology controlled by base station (NodeB);

2)HARQ带软合并技术；2) HARQ with soft combining technology;

3)更短的传输时间间隔(transmission Time interval，TTI)技术。3) Shorter transmission time interval (transmission time interval, TTI) 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物理层的译码性能。Among them, the above-mentioned HARQ combination technology is mainly used for the fast retransmission processing of the physical layer of the Enhanced Dedicated Channel (E-DCH, Enhanced Dedicated Channel), and the decoding of the E-DCH physical layer is improved through the soft combination between the initial transmission and the retransmission performance.

请参照图1，该图是现有技术中在用户终端设备(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：Please refer to FIG. 1, which is a schematic diagram of the processing process of HARQ processing on the E-DCH physical layer on the user terminal equipment (UE) side in the prior art, and its main processing process is as follows:

E-DCH信道编码后的输出N_e，j经过比特(bit)分离处理(bit separation)分离为系统位(Systematic bits)、校验位1(Parity 1bits)和校验位2(Parity 2bits)三个序列；The output N_{e, j} after E-DCH channel coding is separated into three bits (Systematic bits), parity bit 1 (Parity 1bits) and parity bit 2 (Parity 2bits) after bit separation processing (bit separation) sequence;

将该三个序列分别进行速率匹配(Rate Matching，RM)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-DCH Dedicated Physical DataChannel，E-DPDCH)中进行传输。The three sequences are subjected to rate matching (Rate Matching, RM) processing, the three sequences after the rate matching processing are subjected to bit collection processing (bit collection), and the bits after the bit collection processing are mapped to the E-DCH Dedicated physical data channel (E-DCH Dedicated Physical DataChannel, E-DPDCH) 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固定速率的物理信道上进行传输。根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，当速率匹配前的比特数小于速率匹配后的比特数时，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。The main function of the rate matching process is to match the variable number of bits before rate matching to a fixed rate physical channel for transmission. According to the relationship between the number of bits before rate matching and the number of bits after rate matching, it can be divided into two methods: repeated rate matching processing and puncturing rate matching processing. When the number of bits before rate matching is smaller than the number of bits after rate matching, use The repeated rate matching method is used for processing, that is, the bits at certain positions of the sequence before rate matching are repeatedly sent; otherwise, the processing is performed by the puncturing rate matching processing method, that is, the bits at certain positions of the sequence before rate matching are not sent.

HARQ功能受冗余版本(RV)参数控制，RV参数定义如下表一所示：The HARQ function is controlled by the redundancy version (RV) parameter, and the definition of the RV parameter is shown in Table 1 below:

表一：RV参数定义Table 1: RV parameter definition

  E-DCH RV Index(E-DCH冗余版本索引)E-DCH RV Index (E-DCH redundancy version index)  ss  rr  00  1 1  00  1 1  00  00  2 2  1 1  1 1  33  00  1 1

上表一中，s参数用来选择是系统位优先还是校验位优先，会影响速率匹配后系统位和校验位在物理信道中所占的bit数，如果s为1表示系统位优先，速率匹配优先满足系统位，如果s为0表示校验位优先，速率匹配优先满足校验位。r参数用来决定重复速率匹配处理和打孔速率匹配处理的bit起始位置。In the above table 1, the s parameter is used to select whether the system bit is prioritized or the parity bit is prioritized, which will affect the number of bits occupied by the system bit and parity bit in the physical channel after rate matching. If s is 1, the system bit is prioritized. The rate matching first satisfies the system bit, if s is 0, it means the parity bit is first, and the rate matching first satisfies the parity bit. The r parameter is used to determine the bit start position of the repetition rate matching process and the puncturing rate matching process.

HARQ分为蔡斯合并(Chase Combining，简称CC类型)和增量冗余合并(Incremental Redundant Combining，简称IR类型)两种合并类型，采用CC合并类型时，RV Index固定为0；采用IR合并类型时，RV Index会随重传序列号(Repeat Serial Number，RSN)发生变化。HARQ is divided into Chase Combining (Chase Combining, referred to as CC type) and incremental redundancy combining (Incremental Redundant Combining, referred to as IR type). When using CC combining type, RV Index is fixed at 0; using IR combining type , the RV Index will change with the Repeat Serial Number (RSN).

根据不同的HARQ合并类型，NodeB分为仅支持增量冗余合并(Incremental Redundant Combining only，简称IR only)、仅支持蔡斯合并(Chase Combining only，简称CC only)和增量冗余合并及蔡斯合并都支持(IR&CC)的NodeB。According to different HARQ combination types, NodeB is divided into Incremental Redundant Combining only (IR only for short), Chase Combining only (CC only for short) and incremental redundancy combining and Chase Combining only. Both support (IR&CC) NodeB.

表一中的RV Index是由UE发送方控制的，23.331协议中定义了HARQ冗余版本配置信元，如下表二所示：The RV Index in Table 1 is controlled by the UE sender. The HARQ redundancy version configuration information element is defined in the 23.331 protocol, as shown in Table 2 below:

表二：Table II:

  信息元素/组名Information element/group name  Needneed  MultiMulti  类型和参考type and reference  描述 describe  VersionVersion  HARQ冗余版本配置HARQ redundancy version configuration  必须 must  枚举类型(RV)enumerated type (RV)  如果指示为“rv0”，NodeB仅仅使用RVIndex 0。缺省情况下，NodeB将使用基于RSN得到的RVIndex。If the indication is "rv0", NodeB only uses RVIndex 0. By default, NodeB will use the RVIndex obtained based on RSN.  版本6Version 6

协议规定在无线链路建立请求(Radio Link Setup Request)、异步的无线链路重配置请求(Radio Link Reconfiguration Request)、同步的无线链路重配请求Radio Link Reconfiguration Prepare)消息中携带HARQ相关信息，具体的HARQInfo for E-DCH信元定义如下表三所示：The protocol stipulates that HARQ-related information is carried in the radio link setup request (Radio Link Setup Request), asynchronous radio link reconfiguration request (Radio Link Reconfiguration Request), and synchronous radio link reconfiguration request (Radio Link Reconfiguration Prepare) messages. The specific HARQInfo for E-DCH cell definition is shown in Table 3 below:

表三Table three

 信息元素/组名Information element/group name  Presence(呈现状态)Presence  Range(范围)Range (range)  IE Type andReference(信元类型和参数)IE Type and Reference (cell type and parameters)  描述 describe HARQ Info for E-DCHHARQ Info for E-DCH  ENUMERATED(枚举类型)(rv0，rvtable)ENUMERATED (enumeration type) (rv0, rvtable)  如果指示为“rv0”，NodeB仅仅使用RV Index0。如果指示为rvtable，NodeB将使用基于RSN得到的RV Index。If the indication is "rv0", NodeB only uses RV Index0. If it is indicated as rvtable, NodeB will use the RV Index obtained based on RSN.

由于在现有协议中，已规定无线链路建立请求消息中，HARQ Info forE-DCH信元的“Presence”为“M”，即为必选状态，因此，现有技术中，SRNC发送给NodeB的无线链路建立请求消息中每次都将携带HARQ Info for E-DCH信元，将SRNC选择的HARQ合并类型通知给NodeB。Since in the existing protocol, it has been stipulated that in the wireless link establishment request message, the "Presence" of the HARQ Info for E-DCH cell is "M", which is a mandatory state. Therefore, in the prior art, the SRNC sends to the NodeB Each time the wireless link establishment request message will carry the HARQ Info for E-DCH information element, and notify the NodeB of the HARQ combination type selected by the SRNC.

现有协议中，对于无线链路重配置信令(同步无线链路重配置信令或异步无线链路重配置信令)，规定其HARQ Info for E-DCH信元的“Presence”为“O”，即为可选状态。In the existing protocol, for radio link reconfiguration signaling (synchronous radio link reconfiguration signaling or asynchronous radio link reconfiguration signaling), it is stipulated that the "Presence" of its HARQ Info for E-DCH cell is "O ", which is an optional state.

具体地，现有技术中，在一次无线链路建立中，由SRNC根据Qos等业务信息来决定选择IR类型或者CC类型进行HARQ合并；SRNC决定后，会通过NodeB应用部分(Node B Application Part，NBAP)消息和无线网络子系统应用部分(Radio Network Subsystem Application Part，RNSAP)消息通知NodeB使用选择的HARQ合并类型。当NodeB支持SRNC选择的HARQ合并类型，完成无线链路建立或无线链路重配置后，SRNC通过无线资源控制(RadioResource Control，RRC)消息通知UE本次通信使用的HARQ合并类型，UE按照该HARQ合并类型发送数据，NodeB使用该HARQ合并类型进行数据接收合并。Specifically, in the prior art, in the establishment of a wireless link, the SRNC decides to select the IR type or CC type for HARQ combination according to service information such as Qos; after the SRNC decides, it will pass the NodeB Application Part (Node B The NBAP) message and the Radio Network Subsystem Application Part (RNSAP) message notify the NodeB to use the selected HARQ combination type. When the NodeB supports the HARQ combination type selected by the SRNC and completes wireless link establishment or wireless link reconfiguration, the SRNC notifies the UE of the HARQ combination type used in this communication through a Radio Resource Control (RRC) message, and the UE follows the HARQ combination type. The combination type sends data, and the NodeB uses this HARQ combination type to perform data reception and combination.

当NodeB不支持SRNC选择的合并类型时，可以通过NodeB直接反馈，或通过控制无线网络控制器(CRNC)进行反馈，通知SRNC其支持的HARQ合并类型。如果通过CRNC进行反馈，NodeB可以通过审核过程(AuditProcedure)的Audit Response消息或资源状态指示(RESOURCE STATUSINDICATION)过程等告知CRNC其支持的HARQ合并类型。CRNC通过无线链路建立响应消息(RL Setup Response)、异步无线链路重配置响应消息(RLReconfiguration Response)或同步无线链路重配置响应消息(RLReconfiguration Ready)将获知的NodeB支持的HARQ合并类型通知SNRC。When the NodeB does not support the combination type selected by the SRNC, it can directly feed back through the NodeB, or give feedback through the controlling radio network controller (CRNC), and inform the SRNC of the HARQ combination type it supports. If feedback is given through CRNC, NodeB can inform CRNC of the HARQ combination type it supports through the Audit Response message of the audit procedure (AuditProcedure) or the resource status indication (RESOURCE STATUSINDICATION) process. CRNC notifies SNRC of the HARQ combination type supported by NodeB through radio link establishment response message (RL Setup Response), asynchronous radio link reconfiguration response message (RLReconfiguration Response) or synchronous radio link reconfiguration response message (RLReconfiguration Ready) .

通过上述现有技术的描述可知，不管NodeB是CC only、IR only或者(IR+CC)类型，在SRNC发送给NodeB的无线链路建立消息中，都要携带通知NodeB进行HARQ合并的合并类型信元(HARQ Info for E-DCH信元)；即现有技术中SRNC不对NodeB进行类型区分，总是认为NodeB为IR+CC类型。由于无线链路建立消息在网络中使用频率非常高，这样，每个消息都携带HARQ Info for E-DCH信元，将带来比较大的信令开销。其实，对于使用CC only或IR only的NodeB，SRNC只能选用NodeB支持的CC或IR合并类型，因此不必在无线链路建立请求或无线链路重配置请求消息中携带HARQ信息，即当NodeB支持的HARQ类型为CC only或IR only时，在发送给NodeB的无线链路建立消息或无线链路重配置消息中可以不包含HARQ Info for E-DCH信元。It can be seen from the above description of the prior art that no matter whether the NodeB is CC only, IR only or (IR+CC) type, in the wireless link establishment message sent by the SRNC to the NodeB, the combination type information notifying the NodeB to perform HARQ combination must be carried. Element (HARQ Info for E-DCH cell); that is, in the prior art, the SRNC does not distinguish the type of NodeB, and always considers the NodeB to be IR+CC type. Since wireless link establishment messages are used very frequently in the network, each message carries HARQ Info for E-DCH cells, which will bring relatively large signaling overhead. In fact, for NodeBs that use CC only or IR only, the SRNC can only select the CC or IR combination type supported by the NodeB, so it is not necessary to carry HARQ information in the radio link establishment request or radio link reconfiguration request message, that is, when the NodeB supports When the HARQ type is CC only or IR only, the HARQ Info for E-DCH information element may not be included in the radio link establishment message or radio link reconfiguration message sent to the NodeB.

图2为本发明方法流程图。Fig. 2 is a flow chart of the method of the present invention.

具体实施方式Detailed ways

本发明方法的基本原理为：当SRNC获知NodeB支持的HARQ类型为CConly或IR only类型时，在发送给NodeB的RL Setup Request消息中不携带HARQ合并类型信息。The basic principle of the method of the present invention is: when the SRNC learns that the HARQ type supported by the NodeB is CConly or IR only type, the RL Setup Request message sent to the NodeB does not carry the HARQ combination type information.

由于在25.423和25.433协议中，已将RL Setup Request中的HARQ Info forE-DCH信元的Presence规定为必选状态“M”，因此，本发明将该Presence的选择状态从“M”改为“O”。Since in the 25.423 and 25.433 agreements, the Presence of the HARQ Info for E-DCH cell in the RL Setup Request has been specified as the mandatory state "M", therefore, the present invention changes the selection state of the Presence from "M" to " O".

为了实施本发明的方法，SRNC需要获知NodeB支持的HARQ合并类型是CC only、IR only还是CC+IR类型。In order to implement the method of the present invention, the SRNC needs to know whether the HARQ combination type supported by the NodeB is CC only, IR only or CC+IR type.

下面对SRNC如何获取NodeB支持的HARQ合并类型给出详细描述。The following gives a detailed description of how the SRNC obtains the HARQ combination type supported by the NodeB.

一、SRNC为NodeB的CRNC；1. SRNC is the CRNC of NodeB;

CRNC可以获知所管辖的NodeB支持的HARQ合并类型，具体方法为：CRNC can know the HARQ combination type supported by the NodeB under its jurisdiction, the specific method is:

(1)、CRNC向NodeB下发审计请求(AUDIT REQUEST)信令，NodeB返回审计响应(AUDIT RESPONSE)信令，将自身支持的HARQ合并类型信息通知给CRNC；(1), CRNC issues audit request (AUDIT REQUEST) signaling to NodeB, and NodeB returns audit response (AUDIT RESPONSE) signaling, and notifies CRNC of the HARQ combination type information supported by itself;

(2)NodeB通过资源状态指示(RESOURCE STATUS INDICATION)信令主动将自身支持的HARQ合并类型信息通知给CRNC。(2) The NodeB actively notifies the CRNC of the HARQ combination type information supported by itself through the RESOURCE STATUS INDICATION signaling.

当SRNC为NodeB的CRNC时(SRNC-＞Node B)，SRNC通过上面两个方法必然了解NodeB支持的HARQ合并类型，当确定出该Node B支持的HARQ合并类型为CC only或IR only时，SRNC在发送的无线链路建立请求(Radio Link Setup Request)、异步的无线链路重配(Radio Link ReconfigurationRequest)和同步的无线链路重配(Radio Link Reconfiguration Prepare)消息中不必包含携带HARQ合并类型信元，即在上述消息中不携带HARQ Info forE-DCH信元。SRNC在收到相应响应消息，即RL setup Response，RLReconfiguration Response和RL Reconfiguration Ready消息后通过RRC消息告诉UE应采用的HARQ合并类型。When the SRNC is the CRNC of the NodeB (SRNC->Node B), the SRNC must understand the HARQ combination type supported by the NodeB through the above two methods. When it is determined that the HARQ combination type supported by the Node B is CC only or IR only, the SRNC In the sent Radio Link Setup Request (Radio Link Setup Request), asynchronous Radio Link Reconfiguration Request (Radio Link Reconfiguration Request) and synchronous Radio Link Reconfiguration Prepare (Radio Link Reconfiguration Prepare) messages, it is not necessary to include the HARQ combination type information element, that is, the HARQ Info for E-DCH information element is not carried in the above message. After receiving the corresponding response messages, namely RL setup Response, RLReconfiguration Response and RL Reconfiguration Ready messages, the SRNC informs the UE of the HARQ combination type to be adopted through the RRC message.

二、SRNC不是NodeB的CRNC；2. SRNC is not the CRNC of NodeB;

SRNC并不一定是NodeB的CRNC，这样SRNC通过以下方法了解周围RNC下的NodeB支持的HARQ合并类型：The SRNC is not necessarily the CRNC of the NodeB, so the SRNC knows the HARQ combination type supported by the NodeB under the surrounding RNC through the following methods:

方法一、在CRNC了解其所管辖的NodeB支持的HARQ合并类型情况下，通过Iur接口通知周围RNC。Method 1: When the CRNC knows the HARQ combination type supported by the NodeB under its jurisdiction, it notifies the surrounding RNC through the Iur interface.

通知的方式可以是通过Reset过程，在CRNC重起后通知。具体通知方式为现有技术，描述从略。The notification method can be through the Reset process, after the CRNC restarts. The specific notification method is the prior art, and the description is omitted.

还可以通过RNC之间的信息交换(INFORMATION EXCHANGE)过程，将NodeB支持的HARQ合并类型通知给周围RNC。It is also possible to notify the surrounding RNCs of the HARQ combination type supported by the NodeB through the information exchange (INFORMATION EXCHANGE) process between RNCs.

例如：RNC1可以通过信息交换开始请求(INFORMATION EXCHANGEINITIATION REQUEST)消息请求RNC2报告其所管辖的NodeB的支持的HARQ合并类型信息；For example: RNC1 can request RNC2 to report the HARQ combination type information supported by the NodeB under its jurisdiction through the INFORMATION EXCHANGEINITIATION REQUEST message;

RNC2通过信息交换开始响应(INFORMATION EXCHANGE INITIATIONRESPONSE)消息向RNC1报告所管辖的NodeB的HARQ能力信息。RNC2 reports the HARQ capability information of the NodeB under its jurisdiction to RNC1 through an INFORMATION EXCHANGE INITIATIONRESPONSE message.

或者RNC2定期或收集全其所管辖的所有NodeB支持的合并类型后，通过信息报告(INFORMATION REPORT)消息报告给RNC1。Or RNC2 reports to RNC1 through an information report (INFORMATION REPORT) message after periodically or after collecting the merge types supported by all NodeBs under its jurisdiction.

本发明可以使用上述信息交换过程，实现CRNC将自己所管辖的NodeB支持的HARQ合并类型信息通知给周围的RNC。具体方法为：The present invention can use the above information exchange process to realize that the CRNC notifies the surrounding RNCs of the HARQ combination type information supported by the NodeB under its jurisdiction. The specific method is:

周围RNC向CRNC发送信息交换开始请求消息INFORMATIONEXCHANGE INITIATION REQUEST，在该消息中添加请求HARQ信息的HARQ Info信元；The surrounding RNC sends an information exchange start request message INFORMATIONEXCHANGE INITIATION REQUEST to the CRNC, and adds a HARQ Info cell requesting HARQ information to the message;

CRNC返回信息交换开始响应消息INFORMATION EXCHANGEINITIATION RESPONSE，在该消息中添加信元，携带其所管辖的NodeB支持的HARQ合并类型信息。The CRNC returns the information exchange start response message INFORMATION EXCHANGEINITIATION RESPONSE, and adds information elements to the message, carrying the HARQ combination type information supported by the NodeB under its jurisdiction.

或者CRNC定期向周围RNC发送信息报告消息INFORMATIONREPORT，在该消息中添加信元，携带其所管辖的NodeB支持的HARQ合并类型信息；Or the CRNC periodically sends an information report message INFORMATIONREPORT to the surrounding RNC, and adds information elements to the message, carrying the HARQ combination type information supported by the NodeB under its jurisdiction;

或者当CRNC所管辖的NodeB的数量发生变化或所管辖的NodeB支持的HARQ合并类型发生改变时，CRNC向周围RNC发送INFORMATIONREPORT，在该消息中添加信元，携带其所管辖的NodeB支持的HARQ合并类型信息。Or when the number of NodeBs under the jurisdiction of the CRNC changes or the HARQ combination type supported by the NodeBs under its jurisdiction changes, the CRNC sends an INFORMATION REPORT to the surrounding RNCs, adding information elements to the message, carrying the HARQ combination supported by the NodeBs under its jurisdiction type information.

实际网络中，某厂商的RNC下所管辖的NodeB也都是某个厂商的，这样，如果某CRNC下的一个NodeB是IR only、CC only或IR+CC中的一种类型，那么一般来说该CRNC下的其他NodeB也都是这种类型(当然也有例外)。如果CRNC下的全部NodeB都属于同一种类型，即同为IR only类型、CC only类型或IR+CC类型，那么CRNC只要通知周围RNC其自身的合并类型即可，用自身的合并类型来代表其所管辖的全部NodeB都支持该种合并类型，不需要将其所管辖的每一个NodeB的标识及其支持的合并类型都一一进行通知。即：当CRNC所管辖的全部NodeB都支持相同的HARQ合并类型时，在上述添加的信元中，只需携带NodeB支持的HARQ合并类型的对应指示标识；接收端根据所述指示标识解析出所述CRNC所管辖的NodeB都支持的HARQ合并类型。In an actual network, the NodeBs under the jurisdiction of a certain manufacturer's RNC are also owned by a certain manufacturer. In this way, if a NodeB under a certain CRNC is one of IR only, CC only, or IR+CC, then generally speaking The other NodeBs under the CRNC are also of this type (of course there are exceptions). If all the NodeBs under the CRNC belong to the same type, that is, the same type of IR only, CC only, or IR+CC, then the CRNC only needs to notify the surrounding RNCs of its own merge type, and use its own merge type to represent its own All the NodeBs under its jurisdiction support this combination type, and it is not necessary to notify the identity of each NodeB under its jurisdiction and the type of combination it supports. That is: when all the NodeBs under the jurisdiction of the CRNC support the same HARQ combination type, in the above-mentioned added information element, only the corresponding indicator of the HARQ combination type supported by the NodeB needs to be carried; HARQ combination types supported by the NodeBs under the jurisdiction of the CRNC.

当CRNC所管辖的NodeB支持的HARQ合并类型不完全相同时，在上述添加的信元中，需要携带CRNC所管辖的每一个NodeB标识及该NodeB支持的HARQ合并类型信息。When the HARQ combination types supported by the NodeBs under the jurisdiction of the CRNC are not completely the same, the information element added above needs to carry the identity of each NodeB under the jurisdiction of the CRNC and the HARQ combination type information supported by the NodeB.

为此，可以建立上述添加信元的具体定义如下表四所示(仅为一个举例)：For this reason, the specific definition of the above-mentioned added cell can be established as shown in Table 4 (just an example):

表四：Table four:

上表四中，如果CRNC下的全部NodeB都支持同一种HARQ类型，在增加的信元中仅需要携带RNC的合并类型标识“1”、“2”或“3”；周围RNC收到后，根据接收的对应标识进行解析：In Table 4 above, if all NodeBs under the CRNC support the same HARQ type, the added information element only needs to carry the combination type identifier "1", "2" or "3" of the RNC; after the surrounding RNC receives it, Parse according to the received corresponding identifier:

若接收到的标识为“1”，则记录该CRNC管辖的全部NodeB支持的HARQ合并类型为仅支持IR合并类型(IR only)；If the received flag is "1", record the HARQ combination type supported by all NodeBs under the jurisdiction of the CRNC as only supporting the IR combination type (IR only);

若接收到的标识为“2”，则记录该CRNC管辖的全部NodeB支持的HARQ合并类型为仅支持CC合并类型(CC only)；If the received identifier is "2", record the HARQ combination type supported by all NodeBs under the jurisdiction of the CRNC as only supporting CC combination type (CC only);

若接收到的标识为“3”，则记录该CRNC管辖的全部NodeB支持的HARQ合并类型为既支持IR合并类型又支持CC合并类型(IR+CC)。If the received identifier is "3", it is recorded that the HARQ combination type supported by all NodeBs under the jurisdiction of the CRNC supports both the IR combination type and the CC combination type (IR+CC).

若RNC合并类型标识为“4”，表示该CRNC管辖的NodeB并非都是支持同一种HARQ合并类型，这时，需要区分成三种类型，分别将NodeB标识及其支持的HARQ合并类型信息通知给周围RNC。If the RNC merge type identifier is "4", it means that not all NodeBs under the jurisdiction of the CRNC support the same HARQ merge type. At this time, it is necessary to distinguish three types, and notify the NodeB identifier and the HARQ merge type information it supports respectively. Around the RNC.

当然，上面的形式可以进行变化，如CRNC只通知仅支持CC合并类型和仅支持IR合并类型的基站。这样，对于SRNC不了解的基站，SRNC将其认作IR+CC类型。Of course, the above form can be changed, for example, the CRNC only notifies base stations that only support the CC combination type and only support the IR combination type. In this way, the SRNC considers the base stations unknown to the SRNC as IR+CC types.

方法二：通过RNC的学习过程了解NodeB的类型。Method 2: Know the type of NodeB through the learning process of the RNC.

在RNC充当SRNC过程中，如果对某NodeB的类型不了解，在该次通信过程中，指派该NodeB使用一种合并类型，如果该NodeB不支持该指定的合并类型，将返回NodeB的支持的合并类型信息。SRNC记录并存储在本地，从而获得该NodeB的合并类型。即SRNC具有自我学习能力，能将获得的NodeB的合并类型进行记录存储，在下次需要获取该NodeB的合并类型时，查询本地的记录信息即可得知。为防止NodeB更换类型，SRNC可以定期删除或忽略NodeB的合并类型信息，当再次指派该NodeB使用其不支持的合并类型时，根据NodeB的返回信息后再次记录其支持的合并类型。In the process of RNC acting as SRNC, if the type of a NodeB is not known, in the communication process, assign the NodeB to use a combination type, if the NodeB does not support the specified combination type, it will return the NodeB supported combination type information. The SRNC records and stores locally, so as to obtain the merged type of the NodeB. That is to say, the SRNC has self-learning ability, and can record and store the merged type of the obtained NodeB. When the merged type of the NodeB needs to be obtained next time, it can be known by querying the local record information. In order to prevent NodeB from changing its type, SRNC can periodically delete or ignore NodeB’s merge type information, and when reassigning the NodeB to use its unsupported merge type, record the supported merge type again according to the NodeB’s returned information.

方法三：通过操作管理平台(O&M)手工配置。Method 3: Manual configuration through the operation management platform (O&M).

通过操作管理平台将获取的NodeB标识及其支持的HARQ合并类型信息人工配置到所述SRNC中存储。手工配置要求比较高。Manually configure and store the acquired NodeB identity and the HARQ combination type information it supports in the SRNC through the operation management platform. Manual configuration requirements are relatively high.

方法四：通过NodeB重启等过程通知其支持的HARQ合并类型。Method 4: Notifying the NodeB of the supported HARQ combination type through processes such as restarting the NodeB.

当NodeB重启时，将自身支持的HARQ合并类型信息通知与之相连接的所有RNC，包括CRNC和周围其他RNC。When NodeB restarts, it notifies all RNCs connected to it, including CRNC and other surrounding RNCs, of the HARQ combination type information it supports.

方法五：NodeB重启时，将自身支持的HARQ合并类型信息通知到一个公共实体存储。Method five: when the NodeB restarts, it notifies the HARQ combination type information it supports to a public entity for storage.

当NodeB重启时，将自身支持的HARQ合并类型信息通知设置在网络中的一个公共实体保存；SRNC从所述公共实体中定期获取NodeB支持的HARQ合并类型信息。When the NodeB restarts, it notifies a public entity set in the network of the HARQ combination type information supported by itself to save; the SRNC periodically obtains the HARQ combination type information supported by the NodeB from the public entity.

以上所述，为本发明提供的SRNC获取NodeB支持的HARQ合并类型信息的几种具体方法。实际网络中，还可以通过其它的方法获取NodeB支持的HARQ合并类型信息。以上仅是举例，本发明对具体的获取方法不作限定。As mentioned above, there are several specific methods for the SRNC provided by the present invention to obtain the HARQ combination type information supported by the NodeB. In an actual network, the HARQ combination type information supported by the NodeB may also be obtained through other methods. The above are examples only, and the present invention does not limit the specific acquisition method.

本发明将获取到的NodeB支持的HARQ合并类型信息存储到SRNC本地，在SRNC向NodeB发送无线链路建立消息或无线链路重配置消息时，如果查询出该NodeB支持的HARQ合并类型为仅支持CC合并类型(CC only)或者仅支持IR合并类型(IR only)时，则在无线链路建立消息或无线链路重配置消息中不包含携带HARQ合并类型信息的信元；如果查询出NodeB支持的HARQ合并类型为既支持CC合并类型又支持IR合并类型(IR+CC)，则按现有流程处理，即在无线链路建立消息或无线链路重配置消息中携带HARQ合并类型信息，NodeB根据指定的合并类型对接收的数据进行合并处理。The present invention stores the acquired HARQ combination type information supported by the NodeB locally in the SRNC, and when the SRNC sends a wireless link establishment message or a wireless link reconfiguration message to the NodeB, if it is found that the HARQ combination type supported by the NodeB is only supported When the CC combination type (CC only) or the IR combination type (IR only) is only supported, the information element carrying the HARQ combination type information is not included in the radio link establishment message or the radio link reconfiguration message; if the NodeB supports If the HARQ combination type supports both the CC combination type and the IR combination type (IR+CC), it is processed according to the existing process, that is, the HARQ combination type information is carried in the radio link establishment message or the radio link reconfiguration message, and the NodeB Merge the received data according to the specified merge type.

综上所述，本发明方法的具体流程如图2所示，包括如下步骤：In summary, the specific process of the method of the present invention is shown in Figure 2, including the following steps:

步骤S11、将HARQ Info for E-DCH信元的呈现状态“presence”由必选“M”改为可选“O”；Step S11, change the presentation state "presence" of the HARQ Info for E-DCH cell from the mandatory "M" to the optional "O";

步骤S12、SRNC获取并存储基站NodeB支持的HARQ合并类型信息；Step S12, the SRNC obtains and stores the HARQ combination type information supported by the base station NodeB;

步骤S 13、在SRNC向NodeB发送无线链路建立消息或无线链路重配置消息时，查询出该NodeB支持的HARQ合并类型；Step S 13. When the SRNC sends a radio link setup message or a radio link reconfiguration message to the NodeB, query the HARQ combination type supported by the NodeB;

步骤S14、判断NodeB支持的HARQ合并类型是否为CC only或者IR only，如果NodeB支持的HARQ合并类型不是CC only或者IR only，则执行步骤S15；否则，执行步骤S16；Step S14, judging whether the HARQ combination type supported by the NodeB is CC only or IR only, if the HARQ combination type supported by the NodeB is not CC only or IR only, then perform step S15; otherwise, perform step S16;

步骤S15、按照现有技术向NodeB发送无线链路建立消息或无线链路重配置消息；Step S15, sending a radio link establishment message or a radio link reconfiguration message to the NodeB according to the prior art;

步骤S16、SRNC向NodeB发送无线链路建立消息或无线链路重配置消息，在所述无线链路建立消息或无线链路重配置消息中不包含携带HARQ合并类型信息的信元(即不包含HARQ Info for E-DCH信元)。Step S16, SRNC sends radio link establishment message or radio link reconfiguration message to NodeB, in described radio link establishment message or radio link reconfiguration message, do not include the information element that carries HARQ combination type information (that is, do not contain HARQ Info for E-DCH cell).

在上述方法流程中，有可能SRNC保存的NodeB记录不是很全面，当SRNC向NodeB发送无线链路建立消息或无线链路重配置消息时，如果没有在本地查询到该NodeB的记录信息，则采用现有流程处理，即在无线链路建立消息或无线链路重配置消息中携带HARQ合并类型信息，指示该NodeB使用SRNC选择的HARQ合并类型；当NodeB不支持SRNC选择的HARQ合并类型时，向SRNC返回其支持的HARQ合并类型信息；SRNC在本地保存NodeB返回的其支持的HARQ合并类型信息。In the process of the above method, it is possible that the NodeB records saved by the SRNC are not very comprehensive. When the SRNC sends a radio link establishment message or a radio link reconfiguration message to the NodeB, if the record information of the NodeB is not queried locally, then use Existing process processing, that is, carrying HARQ combination type information in the radio link establishment message or radio link reconfiguration message, instructing the NodeB to use the HARQ combination type selected by the SRNC; when the NodeB does not support the HARQ combination type selected by the SRNC, send The SRNC returns the HARQ combination type information it supports; the SRNC locally saves the HARQ combination type information returned by the NodeB.

为了进一步减少信令开销，在SRNC中可以仅存储HARQ合并类型为CConly和IR only的NodeB记录；在SRNC向NodeB发送无线链路建立消息或无线链路重配置消息时，如果没有查询到该NodeB的对应记录，则按现有流程处理。In order to further reduce the signaling overhead, only the NodeB records whose HARQ combination types are CConly and IR only can be stored in the SRNC; when the SRNC sends a radio link establishment message or a radio link reconfiguration message to the NodeB, if the NodeB is not found The corresponding records will be processed according to the existing process.

综上所述，采用本发明方法，当SRNC了解Node B支持的HARQ合并类型为IR only或CC only后，在链路建立的三条消息：Radio Link Setup Request、Radio Link Reconfiguration Request或Radio Link Reconfiguration Prepare中都无需携带HARQ合并类型信息，节省大量信令开销。In summary, using the method of the present invention, when the SRNC understands that the HARQ combination type supported by the Node B is IR only or CC only, three messages in the link establishment: Radio Link Setup Request, Radio Link Reconfiguration Request or Radio Link Reconfiguration Prepare There is no need to carry the HARQ combination type information in the HARQ, which saves a lot of signaling overhead.

显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
