Description

随机接入响应的处理方法、网络设备和终端设备Random access response processing method, network device and terminal device

技术领域technical field

本申请涉及通信领域，具体地，涉及一种随机接入响应的处理方法、网络设备和终端设备。The present application relates to the field of communications, and in particular, to a method for processing a random access response, a network device, and a terminal device.

背景技术Background technique

在随机接入过程中，根据现有规定，网络在为终端设备配置随机接入资源时，针对不同的带宽部分(BWP)或不同的随机接入机会(RACH Occasion，RO)资源，可以支持不同的前导码(preamble)根序列，其中不同的根序列对应不同的preamble序列集合。如果一个小区同时支持两个或两个以上根序列配置，那么有可能出现以下情况：一个前导码索引(preamble index)对应多个根序列，即一个随机接入前导码标识(Random Access Preamble Identifier，RAPID)对应多个preamble序列。In the random access process, according to existing regulations, when configuring random access resources for terminal equipment, the network can support different bandwidth parts (BWP) or different random access opportunity (RACH Occasion, RO) resources. The preamble root sequence of , wherein different root sequences correspond to different sets of preamble sequences. If a cell supports two or more root sequence configurations at the same time, the following situations may occur: a preamble index (preamble index) corresponds to multiple root sequences, that is, a random access preamble identifier (Random Access Preamble Identifier, RAPID) corresponds to multiple preamble sequences.

另一方面，根据现有规定，终端侧通过RAPID判断是否成功接收到网络侧的反馈，若一个RAPID对应的preamble序列不唯一，则网络将无法准确地为终端反馈随机接入响应(Random Access Response，RAR)，这将使后续过程中消息发生碰撞的概率升高。因此，有必要对随机接入过程中的相关处理机制进行优化。On the other hand, according to the existing regulations, the terminal side uses RAPID to determine whether the feedback from the network side has been successfully received. If the preamble sequence corresponding to a RAPID is not unique, the network will not be able to accurately feed back a random access response (Random Access Response) to the terminal. , RAR), which will increase the probability of message collision in the subsequent process. Therefore, it is necessary to optimize the relevant processing mechanism in the random access process.

为了清楚地阐述本申请实施例的思想，首先对通信***中的随机接入过程进行简要描述。In order to clearly illustrate the idea of the embodiments of the present application, a random access process in a communication system is briefly described first.

目前，随机接入机制主要包括基于竞争的随机接入(contention-based random access，CBRA)和基于非竞争随机接入(contention-free random access，CFRA)，其中基于竞争的随机接入CBRA过程主要包括如下步骤：At present, random access mechanisms mainly include contention-based random access (CBRA) and contention-free random access (CFRA), among which the contention-based random access CBRA process mainly It includes the following steps:

步骤1：随机接入资源选择及前导码(Preamble)Step 1: Random access resource selection and preamble (Preamble)

关于随机接入资源的选择，网络通过***信息块SIB1向终端发送随机接入相关参数，其中RACH-ConfigCommon IE中的参数rsrp-ThresholdSSB用于终端的同步信号和广播物理信道块(Synchronization Signal and Physical Broadcast Channel block，SSB)选择，终端将每个SSB下的参考信号接收功率(Reference signal received power，RSRP)测量结果与rsrp-ThresholdSSB进行对比，选择测量值高于所配置阈值的SSB进行接入，若没有满足配置阈值的SSB，则从全部SSB中随机选择一个进行接入。每个SSB对应一组Preamble资源和RO资源，终端从选定的SSB中用于基于竞争的随机接入资源中进行随机选择，将前导码索引(PREAMBLE_INDEX)设置为选定的随机接入Preamble。网络基于接收到的Preamble可以估计上行定时(上行Timing)以及终端传输第三步消息(Msg3)需要的授权(grant)大小。为了让网络可以更准确的了解到待传输的Msg3的大小以分配合适的上行资源，将Preamble分为前导码组(Preamble group)，例如Preamble group A和Preamble group B，若随机接入资源中存在Preamble group B，UE根据Msg3的大小以及路径损耗(pathloss)对Preamble group进行选择。Regarding the selection of random access resources, the network sends random access related parameters to the terminal through the system information block SIB1, where the parameter rsrp-ThresholdSSB in the RACH-ConfigCommon IE is used for the terminal's synchronization signal and broadcast physical channel block (Synchronization Signal and Physical Channel Block). Broadcast Channel block, SSB) selection, the terminal compares the reference signal received power (RSRP) measurement result under each SSB with the rsrp-ThresholdSSB, and selects the SSB whose measurement value is higher than the configured threshold for access. If there is no SSB meeting the configured threshold, one is randomly selected from all SSBs for access. Each SSB corresponds to a set of Preamble resources and RO resources, the terminal randomly selects from the contention-based random access resources in the selected SSB, and sets the preamble index (PREAMBLE_INDEX) as the selected random access Preamble. Based on the received Preamble, the network can estimate the uplink timing (uplink Timing) and the size of the grant (grant) required by the terminal to transmit the third-step message (Msg3). In order to allow the network to more accurately know the size of the Msg3 to be transmitted and allocate appropriate uplink resources, the Preamble is divided into preamble groups, such as Preamble group A and Preamble group B. If there is a random access resource in the Preamble group B, UE selects the Preamble group according to the size of Msg3 and pathloss.

步骤2：网络向终端传输RARStep 2: The network transmits the RAR to the terminal

终端发送第一步消息(Msg1)后开启RAR窗口(ra-ResponseWindow)，在window运行期间接收网络对Msg1的回复，即RAR消息(Msg2)，RAR消息通过随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier)RA-RNTI加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)接收。RA-RNTI根据发送Preamble的物理随机接入信道(Physical Random Access Channel，PRACH)的时频位置计算得到，因此如果多个UE在同一个RO上发送Preamble，则对应的RAR复用在同一个随机接入响应媒体接入控制协议数据单元(RAR Medium Access Control Packet Data Unit，RAR MAC PDU)中。若终端成功接收到与发送Preamble的RO资源对应的RA-RNTI加扰的PDCCH，并且RAR中包含一个媒体接入控制子协议数据单元MAC subPDU所携带的RAPID与步骤1中选择的PREAMBLE_INDEX相对应，则RAR接收成功，终端可解码得到类型分配码(Type Allocation Code，TAC)，上行授权UL Grant和临时小区RNTI(Temporary Cell RNTI，TC-RNTI)，进行步骤3。The terminal opens the RAR window (ra-ResponseWindow) after sending the first step message (Msg1), and receives the network's reply to Msg1 during the operation of the window, that is, the RAR message (Msg2). The RAR message passes through the random access wireless network temporary identifier (Random Access Radio Network Temporary Identifier) RA-RNTI scrambled physical downlink control channel (Physical Downlink Control Channel, PDCCH) reception. The RA-RNTI is calculated according to the time-frequency position of the Physical Random Access Channel (PRACH) that sends the Preamble. Therefore, if multiple UEs send the Preamble on the same RO, the corresponding RARs are multiplexed in the same random access channel. Access response media access control protocol data unit (RAR Medium Access Control Packet Data Unit, RAR MAC PDU). If the terminal successfully receives the PDCCH scrambled by the RA-RNTI corresponding to the RO resource sending the Preamble, and the RAR contains a medium access control sub-protocol data unit MAC subPDU, the RAPID carried by the MAC subPDU corresponds to the PREAMBLE_INDEX selected in step 1, Then the RAR is successfully received, and the terminal can decode to obtain the Type Allocation Code (TAC), the uplink grant UL Grant and the Temporary Cell RNTI (TC-RNTI), and go to step 3.

若在window运行期间没有接收到与发送Preamble的RO资源对应的RA-RNTI加扰的PDCCH，或接收到了RA-RNTI加扰的PDCCH，但RAR中不包含与PREAMBLE_INDEX对应的MAC subPDU，上述两种情况出现时则认为RAR接收失败，此时，若Preamble的传输次数没有超过网络配置的最大传输次数(preambleTransMax)，终端需要对Msg1进行重传，处理如步骤1所述，若Preamble的传输次数超过了网络配置的最大传输次数preambleTransMax，终端向上层上报随机接入问题。If the RA-RNTI scrambled PDCCH corresponding to the RO resource sending the Preamble is not received during the window operation, or the RA-RNTI scrambled PDCCH is received, but the RAR does not contain the MAC subPDU corresponding to PREAMBLE_INDEX, the above two When the situation occurs, it is considered that the RAR reception fails. At this time, if the transmission times of Preamble does not exceed the maximum transmission times (preambleTransMax) configured by the network, the terminal needs to retransmit Msg1. The processing is as described in step 1. If the transmission times of Preamble exceed When the maximum transmission times preambleTransMax configured by the network is set, the terminal reports the random access problem to the upper layer.

步骤3：终端利用调度资源向网络传输无线资源控制(Radio Resource Control，RRC)消息Step 3: The terminal transmits a Radio Resource Control (RRC) message to the network using the scheduling resource

Msg3的消息主要用于通知网络该RACH过程是由何事件触发。比如，如果是初始接入随机过程，则在Msg3中会携带终端设备身份标识(UE ID)和建立原因(Establishment Cause)；如果是RRC重建，则会携带连接态UE标示和establishment cause。Msg3中需要包含UE的唯一标识，用于步骤4中的冲突解决，对于处于连接态(RRC_CONNECTED)的UE来说，其唯一标识小区RNTI(Cell RNTI，C-RNTI)，对于非RRC_CONNECTED状态的UE来说，可使用一个来自核心网的唯一UE标志，如临时移动站标识(Serving-Temporary Mobile Station Identity，S-TMSI)或一个随机数。The message of Msg3 is mainly used to inform the network which event triggers the RACH process. For example, if it is an initial access random process, the terminal equipment identification (UE ID) and establishment cause (Establishment Cause) will be carried in Msg3; if it is RRC reestablishment, it will carry the connected state UE identification and establishment cause. The unique identifier of the UE needs to be included in Msg3, which is used for conflict resolution in step 4. For the UE in the connected state (RRC_CONNECTED), it uniquely identifies the cell RNTI (Cell RNTI, C-RNTI). For the UE in the non-RRC_CONNECTED state For example, a unique UE identifier from the core network, such as a Serving-Temporary Mobile Station Identity (S-TMSI) or a random number, can be used.

步骤4：竞争冲突解决Step 4: Competitive conflict resolution

Msg4有两个作用，第一是用于竞争冲突解决，第二是向终端传输RRC配置消息。终端在发送Msg3后开启定时器(ra-ContentionResolutionTimer)，在定时器(Timer)运行期间，终端监听C-RNTI或TC-RNTI加扰的PDCC。对于处于RRC_CONNECTED态的终端，接收到C-RNTI加扰的PDCCH即认为竞争冲突解决成功；对于处于非RRC_CONNECTED态的终端，接收到TC-RNTI加扰的PDCCH，当成功解码的Msg4对应的MAC PDU中包含的CRID与Msg3发送的公共控制信道SDU(Common Control Channel SDU，CCCH SDU)匹配，即认为竞争冲突解决成功；否则，Timer超时或竞冲突解决失败。若Preamble的传输次数没有超过网络配置的最大传输次数preambleTransMax，终端需要对Msg1进行重传，处理如步骤1所述，若Preamble的传输次数超过了网络配置的最大传输次数preambleTransMax，终端向上层上报随机接入问题。Msg4 has two functions, the first is for contention conflict resolution, and the second is to transmit an RRC configuration message to the terminal. The terminal starts a timer (ra-ContentionResolutionTimer) after sending Msg3, and during the running of the timer (Timer), the terminal monitors the PDCC scrambled by C-RNTI or TC-RNTI. For the terminal in the RRC_CONNECTED state, receiving the PDCCH scrambled by C-RNTI means that the contention conflict is successfully resolved; for the terminal in the non-RRC_CONNECTED state, receiving the PDCCH scrambled by TC-RNTI, when the MAC PDU corresponding to Msg4 is successfully decoded If the CRID contained in it matches the Common Control Channel SDU (Common Control Channel SDU, CCCH SDU) sent by Msg3, it is considered that the contention conflict is successfully resolved; otherwise, the Timer times out or the contention conflict resolution fails. If the number of Preamble transmissions does not exceed the maximum number of transmissions preambleTransMax configured by the network, the terminal needs to retransmit Msg1. The processing is as described in step 1. If the number of transmissions of Preamble exceeds the maximum number of transmissions preambleTransMax configured by the network, the terminal reports a random number to the upper layer. access problem.

相关地，关于随机接入资源配置，根据已有规定，各个带宽部分BWP上用于四步随机接入(4-step RA)和两步随机接入(2-step RA)的前导资源分别通过参数RACH-ConfigCommon和RACH-ConfigCommonTwoStepRA配置，包括PRACH时频资源信息、SSB与RO的映射关系、preamble分组信息、选择资源的阈值、用于生成前导码的根序列等。其中用于生成前导码序列的根序列通过参数prach-RootSequenceIndex/msgA-PRACH-RootSequenceIndex或PRACH preamble format确定。在一种2-step RA过程中，可通过MsgA传输4-step RA中的Msg1和Msg3，可通过MsgB传输4-step RA中的Msg2和Msg4。Relatedly, with regard to the configuration of random access resources, according to existing regulations, the preamble resources used for four-step random access (4-step RA) and two-step random access (2-step RA) on each bandwidth part BWP pass through respectively. The parameters RACH-ConfigCommon and RACH-ConfigCommonTwoStepRA are configured, including PRACH time-frequency resource information, mapping relationship between SSB and RO, preamble grouping information, threshold for selecting resources, root sequence for generating preamble, etc. The root sequence used to generate the preamble sequence is determined by the parameter prach-RootSequenceIndex/msgA-PRACH-RootSequenceIndex or PRACH preamble format. In a 2-step RA process, Msg1 and Msg3 in 4-step RA can be transmitted through MsgA, and Msg2 and Msg4 in 4-step RA can be transmitted through MsgB.

LTE支持139和839两种序列长度，在此基础上，NR针对NR-U场景引入了571和1151两种长度类型，UE根据根序列通过循环移位得到64个ZC(Zadoff-chu)序列，即64个preamble，对应index范围为0到63。为了解决BWP上2-step RA和4-step RA的共存问题，网络支持两种RO和preamble的配置方法，分别如下：LTE supports two sequence lengths of 139 and 839. On this basis, NR introduces two length types of 571 and 1151 for the NR-U scenario. The UE obtains 64 ZC (Zadoff-chu) sequences by cyclic shift according to the root sequence. That is, 64 preambles, and the corresponding index range is 0 to 63. In order to solve the coexistence problem of 2-step RA and 4-step RA on BWP, the network supports two configuration methods of RO and preamble, as follows:

配置一：2-step RA和4-step RA RO共享，preamble分开。也就是，网络从用于四步基于竞争的随机接入(4-step contention-based random access，4-step CBRA)之外的preamble集合中指示用于2-step CBRA的preamble个数。其中用于2-step CBRA的preamble index开始于用于4-step CBRA的preamble index之后。该配置下，RACH-ConfigCommonTwoStepRA中不包含msgA-PRACH-RootSequenceIndex，2-step RA和4-step RA使用相同的根序列。Configuration 1: 2-step RA and 4-step RA RO are shared, and the preamble is separated. That is, the network indicates the number of preambles used for 2-step CBRA from the set of preambles other than those used for 4-step contention-based random access (4-step CBRA). where the preamble index for 2-step CBRA starts after the preamble index for 4-step CBRA. In this configuration, msgA-PRACH-RootSequenceIndex is not included in RACH-ConfigCommonTwoStepRA, and the same root sequence is used for 2-step RA and 4-step RA.

配置二：2-step RA和4-step RA RO分开，preamble共享。也就是，用于2-step和4-step的RO资源在时频域上是分开的，因此SSB与RO的映射关系以及用于CB的preamble的配置是独立的。在该配置下，RACH-ConfigCommon和RACH-ConfigCommonTwoStepRA中都可以包含msgA-PRACH-RootSequenceIndex，即 2-step RA和4-step RA可以使用不同的根序列。Configuration 2: 2-step RA and 4-step RA RO are separated, and the preamble is shared. That is, the RO resources for 2-step and 4-step are separated in the time-frequency domain, so the mapping relationship between SSB and RO and the configuration of preamble for CB are independent. Under this configuration, both RACH-ConfigCommon and RACH-ConfigCommonTwoStepRA can contain msgA-PRACH-RootSequenceIndex, that is, 2-step RA and 4-step RA can use different root sequences.

一方面，根据现有规定，网络在为UE配置随机接入资源时，针对不同的BWP或不同的RO资源集合，可以支持不同的根序列，例如：On the one hand, according to the existing regulations, when configuring random access resources for the UE, the network can support different root sequences for different BWPs or different RO resource sets, for example:

·不同BWP上的RACH配置中的根序列不同；Different root sequences in RACH configurations on different BWPs;

·相同BWP上用于不同RACH类型的根序列不同。• Different root sequences for different RACH types on the same BWP.

不同的根序列对应不同的序列集合，当一个小区同时支持两个及以上根序列配置时，可能会导致一个preamble index对应多个由不同根序列生成的ZC序列，即一个RAPID代表多个preamble序列，如图3所示，一个preamble index对应多个根序列或者说多个preamble序列组。Different root sequences correspond to different sequence sets. When a cell supports two or more root sequence configurations at the same time, one preamble index may correspond to multiple ZC sequences generated by different root sequences, that is, one RAPID represents multiple preamble sequences. , as shown in Figure 3, a preamble index corresponds to multiple root sequences or multiple preamble sequence groups.

另一方面，根据现有规定，UE侧通过RAPID判断是否成功接收到网络侧的反馈，若一个RAPID对应的preamble序列不唯一，则网络无法准确的给UE反馈随机接入响应RAR。如图4所示，不同的UE(例如UE#1、UE#2)所选的preamble具有相同的index(preamble#1、preamble#2)以及不同的根序列(根序列A、根序列B)，且通过PRACH计算的RA-RNTI相同，在此情况下，若网络成功检测到UE#2发送的preamble，根据规定，网络需要通过RA-RNTI加扰的PDCCH向UE发送RAR，并在某个subPDU的子头subheader中包含UE#2发送的preamble对应的RAPID。On the other hand, according to the existing regulations, the UE side determines whether the feedback from the network side is successfully received through RAPID. If the preamble sequence corresponding to a RAPID is not unique, the network cannot accurately feed back the random access response RAR to the UE. As shown in Figure 4, the preambles selected by different UEs (eg UE#1, UE#2) have the same index (preamble#1, preamble#2) and different root sequences (root sequence A, root sequence B) , and the RA-RNTI calculated by PRACH is the same. In this case, if the network successfully detects the preamble sent by UE#2, according to the regulations, the network needs to send the RAR to the UE through the PDCCH scrambled by the RA-RNTI, and in a certain The subheader of the subPDU contains the RAPID corresponding to the preamble sent by UE#2.

但是，由于UE#1和UE#2可能在相同的控制资源集coreset和搜索空间searchspace上通过相同的RA-RNTI检测RAR，那么，网络给UE#2的反馈可能同时被UE#1接收，这将增加下一步消息发生碰撞的概率。可见，有必要对随机接入响应机制进行优化。However, since UE#1 and UE#2 may detect RAR through the same RA-RNTI on the same control resource set coreset and search space searchspace, the feedback from the network to UE#2 may be received by UE#1 at the same time. Will increase the probability of the next message colliding. It can be seen that it is necessary to optimize the random access response mechanism.

鉴于此，本申请实施例提供一种随机接入响应的处理方法，应用于网络设备，参考图5，该方法包括：In view of this, an embodiment of the present application provides a method for processing a random access response, which is applied to a network device. Referring to FIG. 5 , the method includes:

S101，在网络设备接收到一个或多个终端设备发送的前导码之后，所述网络设备发送随机接入响应RAR，所述RAR中包括第一指示信息，所述第一指示信息用于所述一个或多个终端设备区分所述网络设备对接收到的不同前导码的响应，其中不同的前导码对应不同的根序列。S101: After a network device receives a preamble sent by one or more terminal devices, the network device sends a random access response RAR, where the RAR includes first indication information, where the first indication information is used for the One or more terminal devices distinguish the responses of the network device to different preambles received, wherein different preambles correspond to different root sequences.

根据本申请的实施例，网络设备接收到一个或多个终端的前导码之后进行响应，并且在RAR中增加指示信息，该指示信息用于终端设备区分网络设备对接收到的不同前导码的响应，不同的前导码对应不同的根序列；终端设备监听到RAR之后，可通过该指示信息确定监听到的RAR中是否包含对本终端发送的前导码的响应。According to the embodiment of the present application, the network device responds after receiving the preambles of one or more terminals, and adds indication information to the RAR, where the indication information is used by the terminal device to distinguish the responses of the network device to different received preambles , different preambles correspond to different root sequences; after the terminal device monitors the RAR, it can use the indication information to determine whether the monitored RAR contains a response to the preamble sent by the terminal.

因此，利用本申请的实施例，在随机接入过程中终端设备能够对监听到的RAR进行准确判断，如果该RAR是对本终端发送的前导码的响应，可继续进行下一步，如果该RAR不是针对本终端发送的前导码的响应，则需要重新发送消息，避免终端在接收响应时发生混淆。Therefore, using the embodiments of the present application, the terminal device can accurately judge the monitored RAR during the random access process. If the RAR is a response to the preamble sent by the terminal, the next step can be continued. If the RAR is not In response to the response of the preamble sent by the terminal, the message needs to be resent to avoid confusion when the terminal receives the response.

相对应地，本申请实施例还提供一种随机接入响应的处理方法，应用于终端设备，参考图6，该方法包括：Correspondingly, an embodiment of the present application further provides a method for processing a random access response, which is applied to a terminal device. Referring to FIG. 6 , the method includes:

S201，终端设备向网络设备发送第一前导码之后，接收所述网络设备发送的随机接入响应RAR，所述RAR中包括第一指示信息，所述第一指示信息用于所述终端设备区分网络设备对接收到的不同前导码的随机接入响应，其中不同的前导码对应不同的根序列；S201: After a terminal device sends a first preamble to a network device, it receives a random access response RAR sent by the network device, where the RAR includes first indication information, and the first indication information is used by the terminal device to distinguish The random access response of the network device to the received different preambles, wherein different preambles correspond to different root sequences;

S202，所述终端设备根据所述第一指示信息确定接收到的所述RAR中是否包含对所述第一前导码的响应。S202, the terminal device determines, according to the first indication information, whether the received RAR includes a response to the first preamble.

根据本申请的实施例，终端设备能够对监听到的RAR进行准确判断，从而避免终端将网络对其他终端反馈的RAR认定为对本终端反馈的RAR，降低下一步消息发生碰撞的概率。According to the embodiments of the present application, the terminal device can accurately judge the monitored RAR, thereby preventing the terminal from identifying the RAR fed back by the network to other terminals as the RAR fed back to the terminal, and reducing the probability of collision of the next message.

可选地，所述不同的根序列中的至少两个根序列对应的Preamble的前导码索引Preamble Index相同。这里，对于由多个根序列对应的Preamble的Preamble Index相同而导致终端接收响应时发生混淆的情况，如前所述，本申请实施例基于不同的preamble对应的根序列不同，因此通过确定根序列可确定出对应的preamble，区分不同根序列对应的preamble的响应。Optionally, at least two root sequences in the different root sequences have the same preamble index Preamble Index of the Preamble. Here, for the situation that confusion occurs when the terminal receives a response due to the same Preamble Index of the Preambles corresponding to multiple root sequences, as mentioned above, the embodiment of the present application is based on different root sequences corresponding to different preambles. Therefore, by determining the root sequence The corresponding preamble can be determined, and the responses of the preamble corresponding to different root sequences can be distinguished.

相对应地，所述终端设备接收所述网络设备配置的随机接入资源配置，所述随机接入资源配置至少包括根序列和根序列唯一标识。Correspondingly, the terminal device receives a random access resource configuration configured by the network device, where the random access resource configuration at least includes a root sequence and a unique identifier of the root sequence.

可选地，若所述网络设备为所述终端设备配置一组或多组随机接入资源配置，不同的随机接入资源配置对应的根序列不同。Optionally, if the network device configures one or more sets of random access resource configurations for the terminal device, the root sequences corresponding to different random access resource configurations are different.

可选地，所述网络设备当前发送的RAR中包含的第一指示信息与所述网络设备接收到的前导码对应的根序列唯一标识相对应。Optionally, the first indication information contained in the RAR currently sent by the network device corresponds to the unique identifier of the root sequence corresponding to the preamble received by the network device.

可以看到，本申请实施例中不同的根序列具有不同的标识，例如，第一根序列对应的标识为1，第二根序列对应的标识为2，等等。由于根序列与根序列标识是一一对应的关系，因此终端设备在根据RAR中的第一指示信息区分网络对preamble的响应时不会出现混淆的情况。It can be seen that different root sequences in this embodiment of the present application have different identifiers, for example, the identifier corresponding to the first root sequence is 1, the identifier corresponding to the second root sequence is 2, and so on. Since there is a one-to-one correspondence between the root sequence and the root sequence identifier, the terminal device will not be confused when distinguishing the network's response to the preamble according to the first indication information in the RAR.

可选地，所述终端设备根据所述第一指示信息确定接收到的所述RAR中是否包含对第一前导码的响应(其中第一前导码为终端设备向网络设备发送的前导码)，可以按照以下方式处理：Optionally, the terminal device determines, according to the first indication information, whether the received RAR contains a response to the first preamble (wherein the first preamble is a preamble sent by the terminal device to the network device), It can be handled as follows:

·若第一指示信息与第一前导码对应的根序列唯一标识相对应，则终端设备确定接收到的所述RAR中包含对所述第一前导码的响应；If the first indication information corresponds to the unique identifier of the root sequence corresponding to the first preamble, the terminal device determines that the received RAR contains a response to the first preamble;

·若第一指示信息与第一前导码对应的根序列唯一标识不对应，则终端设备确定接收到的所述RAR中不包含对所述第一前导码的响应。· If the first indication information does not correspond to the unique identifier of the root sequence corresponding to the first preamble, the terminal device determines that the received RAR does not contain a response to the first preamble.

在本申请实施例中，所述的第一指示信息可以通过以下多种方式实现，下文将分别进行详细描述：In this embodiment of the present application, the first indication information may be implemented in the following multiple ways, which will be described in detail below:

方式一：所述第一指示信息可以通过随机接入响应媒体接入控制负载RAR MAC payload携带；Mode 1: the first indication information can be carried by the random access response medium access control payload RAR MAC payload;

方式二：所述第一指示信息还可以通过MsgB中的回退随机接入响应媒体接入控制负载fallbackRAR MAC payload携带；Mode 2: the first indication information may also be carried by the fallback random access response medium access control load fallbackRAR MAC payload in MsgB;

方式三：所述第一指示信息还可以通过用于调度随机接入响应的下行控制信息DCI格式携带；Manner 3: The first indication information may also be carried in the downlink control information DCI format used for scheduling random access responses;

方式四：所述第一指示信息还可以通过回退指示媒体接入控制子协议数据单元BI MAC subPDU携带。Manner 4: The first indication information may also be carried by a fallback indication medium access control sub-protocol data unit BI MAC subPDU.

对于方式四，可选地，所述第一指示信息包括BI MAC subPDU中的BI字段所占比特位和第一比特位，其中，For the fourth mode, optionally, the first indication information includes the bits occupied by the BI field in the BI MAC subPDU and the first bit, wherein,

·第一比特位为第二数值时，所述BI字段所占比特位用于指示网络设备当前发送的RAR所对应的前导码的根序列唯一标识。· When the first bit is the second value, the bits occupied by the BI field are used to indicate the unique identifier of the root sequence of the preamble corresponding to the RAR currently sent by the network device.

此外，本申请实施例还提供一种随机接入响应的处理方法，应用于网络设备，参考图7，该方法包括：In addition, an embodiment of the present application also provides a method for processing a random access response, which is applied to a network device. Referring to FIG. 7 , the method includes:

S301，网络设备通过不同的控制资源集coreset向终端设备发送不同根序列的前导码对应的随机接入响应RAR；和/或，网络设备通过不同的搜索空间search space向终端设备发送不同根序列的前导码对应的随机接入响应RAR。S301, the network device sends the random access response RAR corresponding to the preamble of different root sequences to the terminal device through different control resource sets coreset; and/or, the network device sends different root sequences to the terminal device through different search spaces The random access response RAR corresponding to the preamble.

相对应地，本申请实施例还提供一种随机接入响应的处理方法，应用于终端设备，参考图8，该方法包括：Correspondingly, an embodiment of the present application further provides a method for processing a random access response, which is applied to a terminal device. Referring to FIG. 8 , the method includes:

S401，终端设备通过不同的控制资源集coreset接收网络设备发送的不同根序列的前导码对应的随机接入响应RAR；和/或，终端设备通过不同的搜索空间search space接收网络设备发送的不同根序列的前导码对应的随机接入响应RAR。S401, the terminal device receives random access response RARs corresponding to preambles of different root sequences sent by the network device through different control resource sets coreset; and/or, the terminal device receives different root sequences sent by the network device through different search spaces The random access response RAR corresponding to the preamble of the sequence.

也就是说，本申请实施例的网络设备可以通过在不同的coreset和/或不同的search space上发送不同根序列的前导码对应的RAR，以此可视为一种隐式指示的方式，对应地，终端设备如果在例如第一coreset和/或第一search space上监听到了RAR，则说明该RAR就是针对本终端的响应。由于网络设备不会通过该第一coreset和/或第一search space发送对其他终端的响应，因此不会出现终端对接收到的RAR认定混淆的情况。That is to say, the network device in this embodiment of the present application can send RARs corresponding to preambles of different root sequences on different coresets and/or different search spaces, which can be regarded as an implicit indication. Ground, if the terminal device monitors the RAR on, for example, the first coreset and/or the first search space, it means that the RAR is a response to the terminal. Since the network device will not send responses to other terminals through the first coreset and/or the first search space, there will be no situation that the terminal will be confused about the received RAR.

以上通过实施例描述了本申请实施例的随机接入响应的处理方法的实现方式，以下通过多个具体的例子，描述本申请实施例的具体实现过程。The implementation manner of the random access response processing method in the embodiment of the present application is described above through the embodiment, and the specific implementation process of the embodiment of the present application is described below by using a plurality of specific examples.

实施例1Example 1

本实施例中，网络在随机接入响应中携带指示信息，用于区分不同根序列的前导码。根据该指示信息，UE可区分不同随机接入资源配置对应的不同根序列的前导码，以下对实现过程进行详细说明。In this embodiment, the network carries indication information in the random access response, which is used to distinguish preambles of different root sequences. According to the indication information, the UE can distinguish preambles of different root sequences corresponding to different random access resource configurations, and the implementation process will be described in detail below.

参考图9，网络在BWP上配置两组随机接入资源配置，各组随机接入资源配置对应不同的根序列，可表示为：Referring to Figure 9, the network configures two groups of random access resource configurations on the BWP, and each group of random access resource configurations corresponds to different root sequences, which can be expressed as:

·随机接入资源配置#1对应根序列#1，根序列标识位为0；Random access resource configuration #1 corresponds to root sequence #1, and the root sequence identification bit is 0;

·随机接入资源配置#2对应根序列#2，根序列标识位为1；Random access resource configuration #2 corresponds to root sequence #2, and the root sequence identification bit is 1;

UE#1和UE#2分别在两组随机接入资源中选择preamble及用于发送preamble的RO，具体如下： UE#1 and UE#2 select the preamble and the RO used to send the preamble from the two sets of random access resources, as follows:

·UE#1在随机接入资源配置#1中选择preamble及用于发送preamble的RO，其中，UE#1选择的preamble index＝5； UE#1 selects the preamble and the RO used to send the preamble in the random access resource configuration #1, where the preamble index=5 selected by UE#1;

·UE#2在随机接入资源配置#2中选择preamble及用于发送preamble的RO，其中，UE#2选择的preamble index＝5； UE#2 selects the preamble and the RO used to send the preamble in the random access resource configuration #2, where the preamble index selected by UE#2=5;

也就是说，UE#1和UE#2选择了相同的preamble index。需要注意，在此情况下，通过UE#1和UE#2所选RO分别计算的RA-RNTI或MsgB-RNTI或用于接收随机接入响应的RNTI相同。That is, UE#1 and UE#2 have selected the same preamble index. It should be noted that in this case, the RA-RNTI or MsgB-RNTI respectively calculated by the RO selected by UE#1 and UE#2 or the RNTI used for receiving the random access response are the same.

然后，UE#1和UE#2分别发送preamble，之后监听网络通过RA-RNTI、MsgB-RNTI或其他RNTI加扰的PDCCH调度的随机接入响应RAR。Then, UE#1 and UE#2 send the preamble respectively, and then monitor the random access response RAR scheduled by the network through PDCCH scrambled by RA-RNTI, MsgB-RNTI or other RNTI.

其中，根据本申请实施例，为了区分不同随机接入资源配置对应的前导码，网络在RAR中或在MsgB的“fallbackRAR”(回退的RAR消息)中携带指示位，用于区分不同根序列，具体地，可携带在RAR MAC payload或fallbackRAR MAC payload中，如下：Among them, according to the embodiment of the present application, in order to distinguish the preambles corresponding to different random access resource configurations, the network carries an indicator bit in the RAR or in the "fallback RAR" (fallback RAR message) of MsgB, which is used to distinguish different root sequences , specifically, can be carried in the RAR MAC payload or fallbackRAR MAC payload, as follows:

参考图10，可将RAR MAC payload或fallbackRAR MAC payload中的预留bit(例如R bit)比特位设置为指示位，其中，Referring to Figure 10, a reserved bit (eg R bit) bit in the RAR MAC payload or fallback RAR MAC payload can be set as an indication bit, wherein,

·当指示位设置为0时，表示当前RAR subPDU是对选择了资源配置对应的根序列标识位为0的UE的反馈；When the indicator bit is set to 0, it means that the current RAR subPDU is the feedback to the UE whose root sequence identification bit corresponding to the resource configuration is selected as 0;

·当指示位设置为1时，表示当前RAR subPDU是对选择的资源配置对应的根序列标识位为1的UE的反馈(在图9实施例中为对UE#2的反馈)。· When the indication bit is set to 1, it indicates that the current RAR subPDU is the feedback to the UE whose root sequence identification bit corresponding to the selected resource configuration is 1 (in the embodiment of FIG. 9, it is the feedback to UE#2).

其中，指示位或标识位的值，可以为0、1或其他数值。The value of the indication bit or the identification bit may be 0, 1 or other values.

在图9实施例中，UE#1选择了资源配置#1，对应的根序列标识位为0，如果R位的值为0，可确定监听到的RAR是对本UE#1的反馈；反之，如果R位的值不为0，可确定监听到的RAR不是对本UE#1的反馈；In the embodiment of FIG. 9 , UE#1 has selected resource configuration #1, and the corresponding root sequence identification bit is 0. If the value of the R bit is 0, it can be determined that the monitored RAR is the feedback to this UE#1; otherwise, If the value of the R bit is not 0, it can be determined that the monitored RAR is not feedback to the UE#1;

同理，图9实施例的UE#2选择了资源配置#2，对应的根序列标识位为1，如果R位的值为1，可确定监听到的RAR是对本UE#2的反馈；反之，如果R位的值不为1，可确定监听到的RAR不是对本UE#2的反馈。Similarly, UE#2 in the embodiment of FIG. 9 selects resource configuration #2, and the corresponding root sequence identification bit is 1. If the value of the R bit is 1, it can be determined that the monitored RAR is the feedback to this UE#2; otherwise , if the value of the R bit is not 1, it can be determined that the monitored RAR is not feedback to the UE#2.

可以看到，在监听到RAR之后，UE可根据该指示位上的值，对两个或两个以上具有相同preamble index的前导码所对应的不同根序列进行区分，进而，UE可确定当前监听到的RAR是否是对本UE的反馈，并进行后续流程。It can be seen that after monitoring the RAR, the UE can distinguish different root sequences corresponding to two or more preamble codes with the same preamble index according to the value of the indicator bit, and then the UE can determine the current monitoring Whether the received RAR is feedback to the UE, and the follow-up process is performed.

注意到，由于本实施例是利用RAR MAC payload中的比特位(如图10中R位)携带指示位，因此，可以通过改变R位的值实现灵活的指示。Note that since this embodiment utilizes the bits in the RAR MAC payload (such as the R bit in Figure 10) to carry the indication bit, flexible indication can be achieved by changing the value of the R bit.

实施例2Example 2

本实施例中，网络在用于调度随机接入响应的下行控制信息(Downlink Control Information，DCI)格式(format)中携带指示信息，用于区分不同根序列的前导码。根据该指示位UE可区分不同随机接入资源配置对应的不同根序列的前导码，以下对实现过程进行详细说明。In this embodiment, the network carries indication information in a downlink control information (Downlink Control Information, DCI) format (format) used for scheduling a random access response, which is used to distinguish preambles of different root sequences. According to the indicator bit, the UE can distinguish the preambles of different root sequences corresponding to different random access resource configurations, and the implementation process is described in detail below.

网络在某个BWP上配置两组随机接入资源配置，各组随机接入资源配置对应不同的前导码根序列，可表示为：The network configures two groups of random access resource configurations on a BWP, and each group of random access resource configurations corresponds to different preamble root sequences, which can be expressed as:

·随机接入资源配置#2对应根序列#2，根序列标识位为1。· Random access resource configuration #2 corresponds to root sequence #2, and the root sequence identification bit is 1.

与实施例1类似地，UE#1和UE#2选择了相同的preamble，具有相同的preamble index，且通过RO计算得到的RNTI相同；Similar to Embodiment 1, UE#1 and UE#2 have selected the same preamble, have the same preamble index, and have the same RNTI calculated by RO;

UE#1和UE#2在发送preamble后，监听网络通过RA-RNTI或MsgB-RNTI或其他RNTI加扰的PDCCH调度的随机接入响应RAR。After sending the preamble, UE#1 and UE#2 monitor the random access response RAR scheduled by the network through PDCCH scrambled by RA-RNTI or MsgB-RNTI or other RNTI.

其中，根据本申请的实施例，为了区分不同随机接入资源配置对应的前导码，网络利用调度RAR的DCI format中的预留比特位，携带指示位信息，例如：Wherein, according to the embodiment of the present application, in order to distinguish the corresponding preambles of different random access resource configurations, the network uses the reserved bits in the DCI format of the scheduling RAR to carry the indicator bit information, for example:

·当指示位设置为0时，表示当前RAR是对选择资源配置中根序列标识位为0的UE的反馈；When the indicator bit is set to 0, it indicates that the current RAR is the feedback to the UE whose root sequence identification bit in the selection resource configuration is 0;

·当指示位设置为1时，表示当前RAR是对选择资源配置根序列标识位为1的UE的反馈。· When the indication bit is set to 1, it indicates that the current RAR is the feedback to the UE whose identification bit of the selected resource configuration root sequence is 1.

在监听到RAR之后，UE可根据该指示位上的值对两个或两个以上具有相同preamble index的前导码所对应的不同根序列进行区分，进而，UE可确定当前监听到的RAR是否是对本UE的反馈，并进行后续流程。After monitoring the RAR, the UE can distinguish different root sequences corresponding to two or more preambles with the same preamble index according to the value of the indicator bit, and then the UE can determine whether the currently monitored RAR is a Feedback to the UE, and follow-up procedures.

实施例3Example 3

本实施例中，网络通过扩展回退指示媒体接入控制子协议数据单元(Backoff Indicator MAC subPDU，BI MAC subPDU)的方式携带指示信息，用于区分不同根序列前导码。根据该指示信息，UE可区分不同随机接入资源配置对应的不同根序列的前导码，以下对实现过程进行详细说明。In this embodiment, the network carries the indication information by extending the backoff indication medium access control sub-protocol data unit (Backoff Indicator MAC subPDU, BI MAC subPDU) to distinguish different root sequence preambles. According to the indication information, the UE can distinguish preambles of different root sequences corresponding to different random access resource configurations, and the implementation process will be described in detail below.

其中，根据本申请的实施例，为了区分不同随机接入资源配置对应的前导码，扩展现有的BI MAC subPDU，实现指示目的。Wherein, according to the embodiment of the present application, in order to distinguish the corresponding preambles of different random access resource configurations, the existing BI MAC subPDU is extended to realize the indication purpose.

示例性地，参考图11，对其中的与BI字段相邻的预留比特位(如R bit)的含义进行扩展，例如：Exemplarily, referring to Figure 11, the meaning of the reserved bits (such as R bit) adjacent to the BI field is extended, for example:

·当该比特位设置为0时，代表该比特位后的四个bits用于指示BI，When the bit is set to 0, it means that the four bits after the bit are used to indicate BI,

·当该比特位设置为1时，代表该比特位后的四个bits用于指示不同根序列对应的根序列标识位。例如，该比特位后的四个bits为0001，指示的根序列标识位为1。· When the bit is set to 1, it means that the four bits after the bit are used to indicate the root sequence identification bits corresponding to different root sequences. For example, the four bits after this bit are 0001, and the indicated root sequence identification bit is 1.

UE可根据该比特位的值确定对两个或两个以上具有相同preamble index的前导码所对应的不同根序列进行区分，进而，UE可确定当前监听到的RAR是否是对本UE的反馈，并进行后续流程。The UE can determine to distinguish different root sequences corresponding to two or more preambles with the same preamble index according to the value of the bit, and then the UE can determine whether the currently monitored RAR is feedback to the UE, and Follow up process.

实施例4Example 4

本实施例中，网络通过使不同的根序列对应不同的接收coreset或search space，隐式地实现对不同根序列前导码的指示。In this embodiment, the network implicitly indicates different root sequence preambles by making different root sequences correspond to different receiving coresets or search spaces.

·随机接入资源配置#1对应根序列#1；Random access resource configuration #1 corresponds to root sequence #1;

·随机接入资源配置#2对应根序列#2；Random access resource configuration #2 corresponds to root sequence #2;

相应的，不同的根序列对应不同的接收coreset或searchspace；Correspondingly, different root sequences correspond to different receiving coresets or searchspaces;

其中，根据本申请的实施例，为了区分不同随机接入资源配置对应的前导码，网络通过不同的coreset或search space向UE反馈不同根序列对应的RAR；对应地，不同的UE在不同的coreset或searchspace上接收网络侧的反馈，例如，Among them, according to the embodiment of the present application, in order to distinguish the preambles corresponding to different random access resource configurations, the network feeds back the RARs corresponding to different root sequences to the UE through different coresets or search spaces; correspondingly, different UEs in different coresets Or receive feedback from the network side on searchspace, for example,

·UE#1在随机接入资源配置#1对应的coreset或searchspace上接收网络侧的反馈， UE#1 receives feedback from the network side on the coreset or searchspace corresponding to random access resource configuration #1,

·UE#2在随机接入资源配置#2对应的coreset或searchspace上接收网络侧的反馈。· UE#2 receives feedback from the network side on the coreset or searchspace corresponding to random access resource configuration #2.

其中，如果UE在当前的coreset或searchspace上能够接收到网络侧反馈的RAR，则可以确定该RAR就是对本UE的反馈，可以进行下一步；反之，如果UE在当前的coreset或searchspace上未监听到网络侧反馈的RAR，则可以确定RAR接收失败，需重传Msg1。Among them, if the UE can receive the RAR fed back by the network side on the current coreset or search space, it can be determined that the RAR is the feedback to the UE, and the next step can be performed; on the contrary, if the UE does not monitor the current coreset or search space. If the RAR is fed back by the network side, it can be determined that the RAR reception fails and Msg1 needs to be retransmitted.

利用本申请的以上至少一种实施例，当网络同时支持多组根序列配置时，UE可以准确区分网络对不同根序列对应的preamble的响应，避免在接收时发生混淆，通过配置不同的根序列可扩展可用的随机接入资源。Using at least one of the above embodiments of the present application, when the network supports multiple sets of root sequence configurations at the same time, the UE can accurately distinguish the network's responses to preambles corresponding to different root sequences to avoid confusion during reception.
