Description

一种初始测if巨的方法、系统和设备技术领域本发明涉及移动通信技术,特别涉及一种初始测距的方法、系统和设备。 Initial measurement of giant if one kind of methods, systems and apparatus Technical Field The present invention relates to mobile communication technologies, particularly to a method for initial ranging, systems and equipment. 背景技术在移动通信中,如果移动终端(MS)需要与基站(BS)建立通信连接, 必须首先进行通信信道的申请,该通信信道的申请通常采用随机接入的方式。 Background Art In mobile communication, if the mobile terminal (MS) need to communicate with a base station (the BS), must first apply for a communication channel, the communication channel request usually by way of random access. 目前采用的随机接入方法是基于带有快速捕获指示时隙的随机接入碰撞(ALOHA)方式,其中,随机接入过程中的初始测距过程是用于MS获得系统初始上行同步和数据传输所需要的上行带宽的过程。 Random access method currently used is based on the embodiment with random access collisions (the ALOHA) fast acquisition indication time slot, wherein the initial ranging procedure is a random access procedure for the MS to obtain initial system synchronization and uplink data transmission upstream bandwidth required for the process. 图1为现有技术中采用的初始测距的方法流程图,如图l所示,现有技术中的初始测距过程主要包括以下步骤:步骤101: MS在测距接入时刻向BS发送测距码。 The method of FIG. 1 is a flowchart of an initial ranging prior art is employed, as shown in FIG. L, an initial ranging process in the prior art mainly includes the following steps: Step 101: MS sends the BS an access time ranging ranging code. 该步骤中,测距接入时刻是预先定义的专用于MS进行测距的时刻, MS只有等待该时刻的到来才能向BS发送测距码。 In this step, the dedicated ranging predefined access time is performed in a time ranging MS, MS only waiting for the moment to send a ranging code to the BS. MS发送测距码的信道为测距竟争信道。 MS transmits a ranging code to a ranging channel competitive channel. 步骤102: BS判断是否成功接收到测距码,如果成功接收到测距码, 则执行步骤103,如果没有成功接收到测距码,则执行步骤108。 Step 102: BS determines whether the ranging code is received successfully, if the ranging code is received successfully, step 103, if no ranging code is received successfully, step 108 is performed. 步骤103: BS成功接收到测距码后,向MS广播测距响应(RNG-RSP )。 After the BS successfully receives the ranging codes broadcast to the MS a ranging response (RNG-RSP): step 103. 本步骤中,BS成功接收到测距码后,根据测距码进行时间同步和性能偏差的计算,得出发送该测距码的MS需要进行的时间、频率以及功率的调整量,并将该调整量以及标识成功(Success)的状态标识,携带在RNG-RSP 中。 In this step, the BS successfully receives the ranging code, the ranging code according to the time synchronization and calculating deviations in performance, obtain the transmission time adjustment amount, frequency, and power of the MS ranging code is required, and the and identifying successful adjustment amount (success) state identification carried in the RNG-RSP. 其中,功率调整量是MS使用的测距竟争信道需要进行的发射功率调整量。 Wherein the power adjustment amount to adjust the amount of transmit power of the MS a ranging channel used in the competitive need to make. 步骤104: BS通过CDMA分配消息(CDMA_Allocation_IE )向MS发送用于发送测距请求(RNG-REQ)的专用资源信息。 Step 104: BS through the CDMA allocation message (CDMA_Allocation_IE) transmits dedicated resource to the MS transmits a ranging request message (RNG-REQ) of. 步骤105: MS接收到包含Success状态标识的RNG-RSP后,利用CDMA_Allocation_IE中包含的专用资源信息,在该专用资源上向BS发送RNG-REG。 Step 105: After the MS receives the RNG-RSP comprises Success state flag, the use of dedicated resource information included in the CDMA_Allocation_IE, the BS transmits the RNG-REG on the dedicated resource. 步骤106: BS对接收到的RNG-REQ进行解码,判断是否解码成功并且有充足的资源分配给MS,执行步骤107;如果解码不成功或没有充足的资源分配给MS,则执行步骤108或不^L任何操作。 Step 106: BS received RNG-REQ decoding, determines whether the decoding is successful and sufficient resources are allocated to the MS, step 107; if the decoding is unsuccessful or that sufficient resources are allocated to the MS, step 108 is executed or not ^ L any operation. 步骤107: BS向MS发送包含Success状态标识且包含基本连接标识符(Basic CID)的RNG-RSP,结束流程。 Step 107: BS transmits RNG-RSP contains the state identification Success and comprising substantially connection identifier (Basic CID) to the MS, the process ends. 本步骤后,MS接收到该RNG-RSP后,便完成了初始测距过程,可以继续执行后续消息发送过程。 After this step, the MS after receiving the RNG-RSP, the initial ranging process is completed, continue with the next message sending process. 步骤108: BS向MS发送携带继续(Continue)或中断(Abort)状态标识的RNG-RSP。 Step 108: BS transmits to the MS carrying continues (the Continue) or interrupted RNG-RSP (Abort) state flag. 步骤109: MS接收到包含Continue或Abort状态标识的RNG-RSP后, 等待下一个测距接入时刻,然后继续执行步骤101,重新开始发送测试码, 重复执行上述过程,直至接收到包含Success状态标识的RNG-RSP,结束流程。 Step 109: After the MS receives the RNG-RSP comprises Continue Abort state flag or wait for the next ranging access time, and then proceed to step 101, starts to send test pattern, the above-described process is repeatedly performed until receiving state comprising Success RNG-RSP identified, the end of the process. 由以上过程可以看出,现有技术中初始测距的方法中> BS接收到RNG-REQ后,对接收到的RNG-REQ进行解码,如果没有解码成功或没有足够的资源可以分配,则向MS发送包含Continue或Abort状态标识的RNG-RSP,或不做任何操作。 As can be seen from the above process, the prior art method in the initial ranging> BS after receiving the RNG-REQ, RNG-REQ received to decode without the decoding is successful or not enough resources can be allocated, to the MS sends RNG-RSP comprises Continue or Abort state flag, or does nothing. 如果向MS发送包含Continue或Abort状态标识的RNG-RSP,则MS需要等待下一个测距接入时刻重新执行完整的初始测距流程;如果BS没有进行任何操作,则MS会在预先设置的定时时间T 到时,等待下一个测距接入时刻重新执行完整的初始测距流程,其中,预先设置的定时时间T通常为50ms。 If the RNG-RSP transmission or Abort state comprising Continue to the MS ID, the MS needs to wait for the next access time to re-execute a ranging complete initial ranging process; no operation if the BS, the MS may set in advance the timing of when the time T to wait for the next access time to re-execute a ranging complete the initial ranging process, wherein, the preset timer time T is typically 50ms. 所以,如果BS没有对RNG-REQ解码成功 So, if the BS does not decode the success of the RNG-REQ

或没有足够的资源可以分配时,都需要重新发送测距码,执行完整的初始测距流程,会造成很大的接入时延。 There is not enough time or resources can be allocated, you will need to resend ranging code, perform a complete initial ranging process, will cause great access delay. 另外,现有技术中,BS成功接收到测距码后,向MS发送的RNG-RSP 中携带的是针对MS使用的测距竟争信道需要进行的功率调整量,而MS接收到RNG-RSP和CDMA—AllocationJE后,向BS发送的RNG-REQ是在专用资源上发送的,通常专用资源的信道的功率与测距竟争信道的功率并不相同,所以,MS利用BS发送的功率调整量对自身功率进行调整后,使用专用资源发送RNG-REQ并不合适,会使得发送RNG-REQ成功的可靠性较低。 Further, the prior art, the BS successfully receives the ranging code, transmits the RNG-RSP to the MS carries the power adjustment amount for a ranging channel used by the MS competition required, and the MS receives the RNG-RSP and the CDMA-AllocationJE, RNG-REQ sent to the BS is transmitted on dedicated resources, and the power of the ranging channel competitive power of a channel dedicated resources is generally not the same, therefore, the MS by the adjustment amount of the power transmitted by the BS after adjusting power itself, transmit RNG-REQ is not appropriate to use dedicated resources, that will successfully transmitted RNG-REQ less reliable. 发明内容本发明实施例提供了一种初始测距的方法、系统和设备,以1更于减少初始测距中的接入时延。 SUMMARY The embodiment provides a method for initial ranging, the system and apparatus of the present invention to reduce an access delay in a more of an initial ranging. 本发明实施例还提供了一种初始测距的方法、系统和设备,以便于提高初始测距中发送RNG-REQ的可靠性。 Embodiments of the present invention further provides a method of initial ranging, systems, and apparatus, in order to improve reliability of the transmission of the initial RNG-REQ Ranging. 一种初始测3巨的方法,该方法包4舌:基站BS成功接收到移动终端MS在测距接入时刻发送的测距码后,向该MS发送包含第一专用资源信息的CDMA分配消息CDMA_Allocation_IE;BS接收到MS发送的测距请求RNG-REQ后,如果对所述RNG-REQ 解码失败或者没有足够的资源分配给MS用于后续消息发送,则通知MS重新发送RNG-REQ。 CDMA allocation message successfully received by the base station BS the mobile terminal MS transmits a ranging code in a ranging access time to a first MS transmits dedicated resource information comprises: one giant initial measurement method 3, the method tongue 4 CDMA_Allocation_IE; BS after the MS receives a ranging request RNG-REQ transmission, if a failure to decode the RNG-REQ or not enough resources allocated to the MS for a subsequent message transmission, the MS to resend the RNG-REQ. 一种初始测距的方法,该方法包括:MS在测距接入时刻向BS发送测距码;MS接收包含第一专用资源信息的CDMA一AllocationJE,利用该第一专用资源发送RNG-REQ;如果接收到重新发送RNG-REQ的通知,则重新向所述BS发送RNG-REQ。 A method for initial ranging, the method comprising: MS transmits a ranging code to the BS a ranging access time; MS receive CDMA message comprises a first dedicated resource AllocationJE, by using the first dedicated transmission resource RNG-REQ; Upon receiving the RNG-REQ resend the notification, then re-transmits RNG-REQ to the BS. 一种初始测距的系统,该系统包括:BS,用于成功接收到MS在测距接入时刻发送的测距码后,向所述MS发 One kind of initial ranging system, the system comprising: after the BS, a MS successfully received the ranging code transmitted in the ranging access time, sent to the MS

中,采用HARQ的方式。 In using the HARQ method. HARQ是自动请求重传(ARQ)和前向纠错编码(FEC)的结合,ARQ最初是用于保证有线网上的数据通信具有较高的传输质量,当前一次数据尝试传输失败时,就要求重传该数据;FEC是用于保证无线传输环境下,对由于信道噪声、移动性带来的衰落以及其它MS带来的干扰进行的抑制,在传输的数据中增加额外的比特,将两者相结合便产生了HARQ。 When HARQ is automatic repeat request (ARQ) and forward error correction coding in combination (FEC) is, initially for securing the ARQ data communications cable network having a high transmission quality, a current data transfer attempt fails, it requires heavy the data transfer; the FEC are used to ensure the wireless transmission environment, to suppress interference due to channel noise, fading of mobility and other effects will be of the MS, additional bits in the data transmission, the two phases combination will produce a HARQ. 本实施例中采用HARQ的方式实现初始测距过程,如图2所示,该方法可以包括以下步骤:步骤201: BS接收到MS在测距接入时刻发送的测距码。 HARQ of the present embodiment implemented using the embodiment examples initial ranging process, as shown in FIG. 2, the method may comprise the following steps: Step 201: BS the MS transmits a ranging code is received in the ranging access time. 本步骤中,测距接入时刻是预先定义的专门用于MS进行测距的时刻, MS只有等待该时刻的到来才能向BS发送测距码。 In this step, the access time of the ranging is designed for a predefined time ranging the MS, the MS only wait for the time to send a ranging code to the BS. MS在测距接入时刻随机选捧一个测距时隙,并随机选择一个测距码发送到BS。 MS access timing randomly selected Ranging holding a ranging slot, and a randomly selected ranging code to the BS. 本步骤中,可能有多个MS在测距信道上发送测距码,由于测距信道是公共资源,所以,MS以竟争方式利用测距信道传输测距码。 In this step, there may be multiple MS transmits a ranging code in a ranging channel, since the ranging channel is a common resource, so, in a competitive manner using the MS a ranging channel transmission ranging code. 该测距码是MS从特定的一组二进制CDMA码中选择出的,该测距码可以使用双向相移键控(BPSK, Binary Phase Shift Keying)调制方式调制到测距信道的子栽波上。 The MS ranging code is selected from a particular set of binary codes in CDMA, the ranging code can be used bi-phase shift keying (BPSK, Binary Phase Shift Keying) modulation scheme to modulate the ranging sub-channel wave planted on . 步骤202: BS成功接收到测距码后,向MS广播RNG-RSP。 Step 202: After the BS successfully receives the ranging code, RNG-RSP to the MS broadcasts. 本步骤中,由于BS可能会同时接收到多个MS发送的测距码,需要对该多个测距码进行识别,将成功识别出的测距码称为成功接收到的测距码。 In this step, since the BS may simultaneously receive a plurality of the ranging code sent by the MS, the need to identify a plurality of ranging code, the ranging code is successfully identified called successfully received ranging code. 又由于BS并不能区别出接收到的测距码是哪个MS发送来的,所以,需要将包含该测距码信息以及Success状态标识,携带在RNG-RSP中广播给MS 。 Also, because the BS can not distinguish the received ranging codes are transmitted to the MS which, therefore, require the ranging code information including the identity and status of Success, carrying broadcast to the MS in the RNG-RSP. 其中,测距码信息可以包括:接收到的测距码、该测距码所在的时隙,该测距码所在的子信道、或其它测距码相关信息,各MS可以根据测距码信息判断该REG-RSP是否是发送给自身的。 Wherein the ranging code information may include: receiving a ranging code, a ranging slot of the located code, the subchannel ranging code is located, or other ranging code related information, according to the information of each MS may ranging code determining whether the REG-RSP is transmitted to itself. 该RNG-RSP中还可以携带性能调整量。 The RNG-RSP may also carry performance adjustment amount. 性能调整量可以包括:发送该测距码的MS需要进行的时间、频率以及功率的调整量。 Performance adjustment amount may include: adjusting the amount of time an MS transmitting the ranging code is required, the frequency and power. 步骤203: BS通过CDMA_Allocation—IE向MS发送用于发送RNG-REQ Step 203: BS transmits to the MS transmits a RNG-REQ by CDMA_Allocation-IE

的第一专用资源信息。 The first dedicated resource information. 在本步骤之后,MS接收到包含Success状态标识的RNG-RSP以及CDMA—Allocation—IE后,根据RNG-RSP中的性能调整量对自身的性能参数进行调整,根据CDMA_Allocation—IE中包含的专用资源信息,在该专用资源上向BS发送RNG-REQ。 After following this step, the MS receives the RNG-RSP and a CDMA-Allocation-IE comprises Success state identification, the amount of adjustment capability RNG-RSP is adjusted to its performance parameters, the dedicated resource CDMA_Allocation-IE included in accordance with information, transmits RNG-REQ to the BS on the dedicated resource. 在BS成功接收到测距码后,上述步骤202和步骤203中,向MS广播包含Success状态标识的RNG-RSP以及通过CDMA—Allocation—IE向MS发送用于发送RNG-REQ的专用资源信息可以是先后发生,也可以是同时发生。 After the BS ranging code is received successfully, step 202 and step 203, the MS broadcasts a Success state flag and the RNG-RSP dedicated resources for transmitting the RNG-REQ transmitted by CDMA-Allocation-IE to the MS information may that has happened, it can occur simultaneously. 步骤204: BS对接收到的RNG-REQ进行解码,判断是否解码成功并且有充足的资源分配给MS用于后续消息发送,如果否,则执行步骤205;如果是,则执行步骤207。 Step 204: BS received RNG-REQ decoding, determines whether the decoding is successful and sufficient resources are allocated to the MS for transmitting subsequent messages, and if not, step 205; if yes, step 207 is executed. 本步骤中所述分配给MS的资源是用于MS下一次发送消息给BS的资源。 This step the resources allocated to the MS is used for sending messages to the BS the MS resources. 步骤205:向MS发送一个否定应答(NACK)指示。 Step 205: MS sends a negative acknowledgment (NACK) indication. 在HARQ中,通知MS进行重传的方式是向MS发送NACK。 In HARQ, the MS notifies the retransmission mode sends a NACK to the MS. 在该步骤之后,MS接收到NACK指示,则重新利用上一次发送RNG-REQ的专用资源向BS重传RNG-REQ。 After this step, the MS receives the NACK indication, the re-use of resources dedicated transmission time RNG-REQ to the BS retransmits RNG-REQ. 步骤206: BS接收到MS重传的RNG-REQ,根据不同的HARQ类型执行相应的处理,并转至步骤204。 Step 206: BS to the MS receiving the retransmitted RNG-REQ, performing corresponding processing according to the different types of HARQ, and go to step 204. HARQ可以有三种类型,第一种类型中,MS向BS发送的RNG-REQ 中包含循环冗余校验(CRC, Cyclical Redundancy Check ),并用前向纠错(FEC, Forward Error Correction)编码;重传的RNG-REQ编码与第一次相同,BS只需要对接收到的RNG-REQ进行解码。 HARQ can be of three types, the first type, RNG-REQ MS transmits to the BS contains a cyclic redundancy check (CRC, Cyclical Redundancy Check), and with forward error correction (FEC, Forward Error Correction) coding; weight RNG-REQ and the second pass encoding same time, BS only docking RNG-REQ received decoded. 第二种类型中,MS在首次向BS发送的RNG-REQ中没有或带有少量的冗余,重传的RNG-REQ并不是原来的RNG-REQ,而是增加了其中的冗余部分,此时BS需要对将重传的RNG-REQ和緩存的前一次的RNG-REQ进行合并,然后进行解码。 The second type, the MS does not transmit the RNG-REQ to the BS for the first time or with a small amount of redundancy, retransmission is not the original RNG-REQ RNG-REQ, but wherein the redundant portion increases, At this time, the BS needs to pre retransmission buffer RNG-REQ and RNG-REQ once merged, and then decoded. 第三种类型中,重传的RNG-REQ中的码字具有自解码能力,此时,BS可以直接从重传的RNG-REQ中解码,也可以将重传的RNG-REQ和緩存的前一次的RNG-REQ进行合并后解码。 The third type, the retransmitted codeword has a RNG-REQ from the decoding capability, the former case, the retransmission to the BS directly in the RNG-REQ decoding, may also be retransmitted RNG-REQ and the primary cache decodes the RNG-REQ merge. 如果在循环执行步骤204至206的过程中,始终不能成功解码RNG-REQ,则可以i殳定一个次数阈值,在通知MS重新发送RNG - REQ的步骤之前还包括:判断MS重新发送RNG - REQ的次数是否达到设定的阈值,如果重新发送的次数达到设定的次数阈值时,不再通知MS进行重传, MS等待定时时间T到时,重新执行步骤201进行竟争地发送测距码。 If the process loops to step 204 to 206, and always not successfully decoded RNG-REQ, may be i Shu set a threshold number, in the MS to resend RNG - before REQ step further comprises: determining MS to resend RNG - REQ when the number reaches a set threshold, if the number of retransmission times reaches a set threshold, no retransmission inform the MS, the MS waits for timer time T, step 201 again transmits a ranging code for competition . 还可以设定一个时间阈值,当距离上次通知MS进行重传的时间达到该时间阈值时,不再通知MS进行重传,MS等待定时间T到时,重新执行步骤201进行竟争地发送测距码。 Can also set when a time threshold, when the time since the last retransmission inform the MS of the time to reach the threshold, retransmission is not inform the MS, the MS waits for a predetermined time T, step 201 is performed again for competitive transmitted ranging code. 步骤207: BS向MS发送一个包含Basic CID的RNG-RSP,结束流程。 Step 207: BS transmits an RNG-RSP contains the Basic CID to the MS, the process ends. 本步骤之后,MS接收到该RNG-RSP后,便完成了初始测距过程,可以继续执行下面的消息发送过程。 After this step, the MS after receiving the RNG-RSP, the initial ranging process is completed, the following message may continue sending process. 图3为本发明实施例提供的初始测距的第二种方法流程图,在该实施例中,采用重新发送CDMA—Allocation一IE的方式,如图3所示,该方法可以包括以下步骤:步骤301至步骤302同图2中所述的步骤201至202。 FIG 3 is a flowchart of a second method the initial ranging to an embodiment of the present invention, in this embodiment, by way of re-transmitting a CDMA-Allocation IE is shown in Figure 3, the method may comprise the steps of: the procedure with the steps 301 to 302 in FIG. 2 201-202. 步骤303: BS通过CDMA—Allocation—IE向MS发送用于发送RNG-REQ 的专用资源信息。 Step 303: BS transmits dedicated resource for transmitting the RNG-REQ message to the MS by the CDMA-Allocation-IE. 步骤304: BS对接收到的RNG-REQ进行解码,判断是否解码成功并且有充足的资源分配给MS,如果是,则执行步骤305;如果否,则执行步骤303。 Step 304: BS received RNG-REQ decoding, determines whether the decoding is successful and sufficient resources are allocated to the MS, if yes, step 305 is performed; if not, then step 303 is performed. 在本步骤中,如果没有解码成功或者没有充足的资源分配给MS,则BS 会重新发送一个CDMA—Allocation—IE给MS,其中包含了MS用于发送RNG-REQ的专用资源信息,通常,重新发送的专用资源信息与前一次的专用资源信息并不相同,MS接收到该CDMA—Allocation—IE后,会在新的专用资源上向BS发送RNG-REQ。 In this step, if decoding is successful or not sufficient resources are not allocated to the MS, the BS may resend a CDMA-Allocation-IE to the MS, wherein the MS information includes dedicated resource for transmitting the RNG-REQ, usually, re dedicated resource information transmitted in the dedicated resources and a message is not the same, the MS receiving the CDMA-Allocation-IE, the RNG-REQ sent to the BS on the new dedicated resources. 也就是说,重复执行步骤303至304,直到BS解码成功并且有充足的资源分配给MS,或者,直到定时时间T到时。 That is, steps 303-304 are repeatedly performed until the decoding is successful and the BS sufficient resources are allocated to the MS, or to the time T until the timing. 步骤305: BS向MS发送一个包含Basic CID的RNG-RSP,结束流程。 Step 305: BS transmits an RNG-RSP contains the Basic CID to the MS, the process ends. 本步骤中包含Basic CID的RNG-RSP还可以包含Success状态标识。 RNG-RSP Basic CID included in the present step may also comprise Success state identification. 本步骤中,BS向MS发送的RNG-RSP中可以包含Success状态标识。 In this step, RNG-RSP BS transmits to the MS identification may comprise Success state. 在本步骤之后,MS接收到该RNG-RSP后,便完成了初始测距过程,可以继续执行下面的消息发送过程。 After following this step, the MS receives the RNG-RSP, the initial ranging process is completed, the following message may continue sending process. 在以上的两种方式中,由于电气和电子工程协会(IEEE) 802.16e标准中的通用帧长目前的推荐值为5ms,所以,BS在解码不成功或者没有足够的资源分配给MS用于消息发送时,向MS发送NACK和MS向BS重新发送CDMA—Allocation—IE的时间之和比定时时间T小得多。 In the above two methods, since the Institute of Electrical and Electronics Engineers (IEEE) 802.16e standard frame length common current recommended value 5ms, therefore, the decoding is unsuccessful or the BS does not have enough resources allocated to the MS a message sending, to the MS and the MS sends a NACK to resend the CDMA-Allocation-IE time and time T is much smaller than the timing to the BS. 上述过程为执行该方法时BS端的相应操作,在MS端执行的方法为:MS接收到重新发送RNG-REQ的通知后,重新向BS发送RNG-REQ。 The above process is the corresponding operation that the BS performing the method, in a method for performing MS side: MS after receiving the re-send notice of RNG-REQ, RNG-REQ resend to the BS. 图4为本发明实施例提供的MS端的方法流程图,如图4所示,该MS执行的操作包括以下步骤:步骤401: MS在测距接入时刻向BS发送测距码。 The method of FIG. 4 MS terminal according to an embodiment of the present invention, a flow chart shown in Figure 4, the MS performs the operation comprises the following steps: Step 401: MS transmits a ranging code to the BS a ranging access time. 步骤402: MS接收BS发送的CDMA—Allocation—正。 Step 402: MS positive BS receiving CDMA-Allocation- transmitted. 步骤403:根据该CDMA_Allocation_IE中的专用资源信息,在该专用资源上发送RNG-REQ。 Step 403: based on the dedicated resource information in the CDMA_Allocation_IE, RNG-REQ transmission on the dedicated resource. 在该步骤403之后,MS根据接收到的消息不同,可以分为以下三个并列的步骤:步骤404a:如果接收到BS发送的重新发送RNG-REQ的通知,则重新向BS发送RNG-REQ,即重新执行步骤403。 After this step 403, MS depending on the received message can be divided into the following three steps in parallel: Step 404a: Upon receiving the RNG-REQ resend the notification sent by the BS, re-transmits RNG-REQ to the BS, That re-execute step 403. 本步骤中,如果MS接收到BS发送的NACK,则重新利用上一次发送RNG-REQ的专用资源向BS重传RNG-REQ。 In this step, if the MS receives the BS NACK transmitted, re-transmitted using dedicated resources on a RNG-REQ to the BS retransmits RNG-REQ. 如果MS接收到BS发送的CDMA—Allocation—IE ,则利用当前接收到的CDMA—Allocation—IE指示的专用资源发送RNG-REQ。 If the MS receives CDMA-Allocation-IE BS transmitted using dedicated resources is currently received CDMA-Allocation-IE indicating a transmission RNG-REQ. 步骤404b:如果MS接收到BS发送的包含Basic CID的RNG-RSP,则MS可以按照现有技术中的流程继续执行后续消息发送的过程。 Step 404b: If the MS receives the RNG-RSP transmission comprising a BS Basic CID, the MS may continue to perform the process subsequent messages sent in accordance with the prior art processes. 步骤404c:如杲定时时间T到时,并且MS尚没有接收到包含Basic CID 的RNG-RSP,则MS重新执行步骤401。 Step 404c: Gao as the timing when the time T, and the MS is not yet received the RNG-RSP contains the Basic CID, the MS performs step 401 again. 即等待下一个测距接入时刻向BS 发送测距码,重新开始初始测距过程。 I.e. wait for a next access time ranging transmits a ranging code to the BS, the initial ranging process is restarted. 为了描述清晰,将上述通过CDMA—Allocation—IE第一次发送的专用资源信息称为第一专用资源信息,用于通知MS进行重传的CDMA—Allocation—IE携带的专用资源信息称为第二专用资源信息。 For clarity of description, the above-described dedicated resource CDMA-Allocation-IE through the first transmission information is called a first dedicated resource information, for notifying the MS dedicated resource information retransmission CDMA-Allocation-IE carried termed a second dedicated resource information. 图5为本发明实施例提供的初始测距的第一种系统结构图,如图5所示, 该系统可以包括:BS 500和MS 510。 FIG 5 a first initial ranging system configuration diagram according to an embodiment of the present invention, shown in Figure 5, the system may include: BS 500 and MS 510.
