In the two-step random access process, the message 1 (Message 1, Msg 1) and message 3 in the four-step random access process can be (Msg 3) is sent as the first message (Message A, MsgA) in the two-step random access process, and the message 2 (Msg2) and message 2 (Msg 4) in the four-step random access process are sent as two-step The second message (Message B, MsgB) in the random access process is sent. However, since a terminal device in an idle state or a deactivated state does not have Cell Radio Network Temporary Identity (C-RNTI) information during the two-step random access process, what happens after the terminal device sends the MsgA? Blind detection of MsgB is an urgent problem to be solved.

在小区搜索过程之后，终端设备已经与小区取得了下行同步，因此终端设备可以接收下行数据。但终端设备只有与小区取得上行同步，才能进行上行传输。终端设备可以通过随机接入过程(Random Access Procedure)与小区建立连接并取得上行同步。为了便于理解本申请实施例的方案，下面将结合图2简单介绍随机接入过程。After the cell search process, the terminal device has achieved downlink synchronization with the cell, so the terminal device can receive downlink data. However, the terminal device can perform uplink transmission only when it obtains uplink synchronization with the cell. A terminal device can establish a connection with a cell and obtain uplink synchronization through a random access procedure (Random Access Procedure). In order to facilitate the understanding of the solution of the embodiment of the present application, the following will briefly introduce the random access process with reference to FIG. 2 .

随机接入过程通常可以由以下事件触发：The random access process can usually be triggered by the following events:

(1)初始接入(Initial Access)。(1) Initial Access (Initial Access).

终端设备可以从无线资源控制(Radio Resource Control，RRC)空闲态(RRC_IDLE态)进入RRC连接态(RRC_CONNECTED)。A terminal device may enter an RRC connected state (RRC_CONNECTED) from a radio resource control (Radio Resource Control, RRC) idle state (RRC_IDLE state).

(2)RRC连接重建过程(RRC Connection Re-establishment procedure)。(2) RRC Connection Re-establishment procedure (RRC Connection Re-establishment procedure).

(3)切换(Handover)。(3) Handover (Handover).

此时，终端设备处于连接态，需要与新的小区建立上行同步。At this point, the terminal device is in a connected state and needs to establish uplink synchronization with the new cell.

(4)RRC连接态下，下行数据或上行数据到达时，上行处于“不同步”状态(DL or ULdata arrival during RRC_CONNECTED when UL synchronisation status is″non-synchronised″)。(4) In the RRC connection state, when the downlink data or uplink data arrives, the uplink is in the "non-synchronized" state (DL or ULdata arrival during RRC_CONNECTED when UL synchronization status is "non-synchronized").

(5)RRC连接态下，上行数据到达时，没有可用的物理上行控制信道(PhysicalUplink Control Channel，PUCCH)资源用于调度请求(Scheduling Request，SR)传输(ULdata arrival during RRC_CONNECTED when there are no PUCCH resources for SRavailable)。(5) In the RRC connected state, when uplink data arrives, there are no available physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources for scheduling request (Scheduling Request, SR) transmission (ULdata arrival during RRC_CONNECTED when there are no PUCCH resources for SR Available).

(6)SR失败(SR failure)。(6) SR failure (SR failure).

(7)RRC在同步配置时的请求(Request by RRC upon synchronousreconfiguration)。(7) Request by RRC upon synchronous reconfiguration (Request by RRC upon synchronous reconfiguration).

(10)终端设备请求其他系统信息(Other System Information，OSI)。(10) The terminal device requests other system information (Other System Information, OSI).

(11)终端设备需要进行波束(Beam)失败的恢复(Beam failure recovery)。(11) The terminal device needs to perform beam failure recovery (Beam failure recovery).

在NR系统中，可以支持两种随机接入方式：基于竞争的随机接入方式和基于非竞争的随机接入方式。下面简单描述基于竞争的四步随机接入过程，如图2所示，四步随机接入过程包括：In the NR system, two random access methods can be supported: a contention-based random access method and a non-contention-based random access method. The following briefly describes the contention-based four-step random access process, as shown in Figure 2, the four-step random access process includes:

步骤1，终端设备向网络设备发送随机接入前导码(Preamble，也即message1，Msg1)。Step 1, the terminal device sends a random access preamble (Preamble, ie message1, Msg1) to the network device.

其中，随机接入前导码也可以称为前导码、随机接入前导码序列、前导码序列等。Wherein, the random access preamble may also be referred to as a preamble, a random access preamble sequence, a preamble sequence, and the like.

具体而言，终端设备可以选择物理随机接入信道(Physical Random AccessChannel，PRACH)资源，PRACH资源可以包括时域资源、频域资源和码域资源。接下来，终端设备可以在选择的PRACH资源上发送选择的Preamble。网络设备可以根据Preamble估计其与终端设备之间的传输时延并以此校准上行定时(timing)，以及可以大体确定终端设备传输消息3(Msg 3)所需要的资源大小。Specifically, the terminal device may select physical random access channel (Physical Random Access Channel, PRACH) resources, and the PRACH resources may include time domain resources, frequency domain resources, and code domain resources. Next, the terminal device can send the selected Preamble on the selected PRACH resource. The network device can estimate the transmission delay between itself and the terminal device according to the Preamble, and use this to calibrate the uplink timing (timing), and can generally determine the resource size required by the terminal device to transmit the message 3 (Msg 3 ).

步骤2，网络设备向终端设备发送随机接入响应(Random Access Response，RAR，也即message2，Msg2)Step 2, the network device sends a random access response (Random Access Response, RAR, that is, message2, Msg2) to the terminal device

终端设备向网络设备发送Preamble后，可以开启一个RAR窗口，在该RAR窗口内根据随机访问无线网络临时标识符(Random Access Radio Network TemporaryIdentifier，RA-RNTI)检测对应的物理下行控制信道(Physical Downlink ControlChannel，PDCCH)。若终端设备检测到RA-RNTI加扰的PDCCH后，可以获得该PDCCH调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。其中，该PDSCH中包括Preamble对应的RAR。After the terminal device sends the Preamble to the network device, it can open a RAR window, and in the RAR window, detect the corresponding Physical Downlink Control Channel (Physical Downlink ControlChannel) according to the random access radio network temporary identifier (Random Access Radio Network Temporary Identifier, RA-RNTI). , PDCCH). After detecting the PDCCH scrambled by the RA-RNTI, the terminal device can obtain a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the PDCCH. Wherein, the PDSCH includes the RAR corresponding to the Preamble.

如果在此RAR窗口内没有接收到网络设备回复的RAR，则终端设备可以认为此次随机接入过程失败。应理解，终端设备和网络设备都需要唯一地确定RA-RNTI的值，否则终端设备就无法解码RAR。If no RAR replied by the network device is received within the RAR window, the terminal device may consider that the random access process has failed. It should be understood that both the terminal device and the network device need to uniquely determine the value of RA-RNTI, otherwise the terminal device cannot decode the RAR.

可选地，本申请实施例中，RA-RNTI可以通过收发双方都明确的Preamble的时频位置来计算RA-RNTI的值。比如，与Preamble相关联的RA-RNTI可以通过公式1计算：Optionally, in this embodiment of the present application, the RA-RNTI can calculate the value of the RA-RNTI based on the time-frequency position of the Preamble that is specified by both the transmitting and receiving parties. For example, the RA-RNTI associated with the Preamble can be calculated by Formula 1:

RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_c_id 公式1RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_c_id Formula 1

其中，s_id为PRACH资源的第一个正交频分复用(Orthogonal FrequencyDivision Multiplexing，OFDM)符号的索引(0≤s_id＜14)，t_id为一个系统帧中PRACH资源的第一个时隙的索引(0≤t_id＜80)，f_id为频域中PRACH资源的索引(0≤f_id＜8)，ul_c_id为用于传输Preamble的上行载波(0表示正常上行链路(Normal Uplink，NUL)载波，1表示补充上行链路(Supplementary Uplink，SUL)载波)。对于频分复用(Frequency DivisionDuplexing，FDD)而言，每个子帧只有一个PRACH资源，因此，f_id固定为0。Among them, s_id is the first Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol index (0≤s_id<14) of the PRACH resource, and t_id is the index of the first time slot of the PRACH resource in a system frame (0≤t_id<80), f_id is the index of the PRACH resource in the frequency domain (0≤f_id<8), ul_c_id is the uplink carrier used to transmit the Preamble (0 means normal uplink (Normal Uplink, NUL) carrier, 1 Indicates a supplementary uplink (Supplementary Uplink, SUL) carrier). For frequency division duplexing (Frequency Division Duplexing, FDD), each subframe has only one PRACH resource, therefore, f_id is fixed at 0.

换句话说，由于终端设备发送的Preamble时频位置是确定的，网络设备在解码Preamble时，也获得了该Preamble的时频位置，进而可以知道RAR中需要使用的RA-RNTI。当终端设备成功地接收到一个RAR(使用确定的RA-RNTI来解码)，且该RAR中的随机访问序列标识符(Random Access Preamble Identifier，RAPID)与终端设备发送的Preamble index相同时，则可以认为成功接收了RAR，此时终端设备就可以停止检测RA-RNTI加扰的PDCCH了。In other words, since the time-frequency position of the Preamble sent by the terminal device is determined, the network device also obtains the time-frequency position of the Preamble when decoding the Preamble, and thus can know the RA-RNTI to be used in the RAR. When the terminal device successfully receives a RAR (decoded using the determined RA-RNTI), and the random access sequence identifier (Random Access Preamble Identifier, RAPID) in the RAR is the same as the Preamble index sent by the terminal device, you can Considering that the RAR has been received successfully, the terminal device can stop detecting the PDCCH scrambled by the RA-RNTI at this time.

步骤3，终端设备发送Msg 3。Step 3, the terminal device sends Msg 3.

终端设备在收到RAR消息后，判断该RAR是否为属于自己的RAR消息，例如终端设备可以利用前导码索引进行核对，在确定是属于自己的RAR消息后，可以在RRC层产生Msg 3，并向网络设备发送Msg 3，其中需要携带终端设备的标识信息等。After receiving the RAR message, the terminal device judges whether the RAR is its own RAR message. For example, the terminal device can use the preamble index to check. After determining that it is its own RAR message, it can generate Msg 3 at the RRC layer, and Send Msg 3 to the network device, which needs to carry the identification information of the terminal device and so on.

其中，Msg 3主要用于通知网络设备该随机接入的触发事件。针对不同的随机接入触发事件，终端设备在步骤3中发送的Msg 3可以包括不同的内容。Wherein, Msg 3 is mainly used to notify the network device of the random access trigger event. For different random access trigger events, the Msg 3 sent by the terminal device in step 3 may include different content.

例如，对于初始接入的场景，Msg 3可以包括RRC层生成的RRC连接请求消息(RRCSetup Request)。此外，Msg3还可以携带例如终端设备的5G-服务临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)或随机数等。For example, for the initial access scenario, Msg 3 may include an RRC connection request message (RRCSetup Request) generated by the RRC layer. In addition, Msg3 may also carry, for example, a 5G-Serving Temporary Mobile Subscriber Identity (Serving-Temporary Mobile Subscriber Identity, S-TMSI) or a random number of the terminal device.

又例如，对于RRC连接重建场景，Msg 3可以包括RRC层生成的RRC连接重建请求消息(RRC Reestabilshment Request)。此外，Msg 3还可以携带例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)等。For another example, for an RRC connection reestablishment scenario, Msg 3 may include an RRC connection reestablishment request message (RRC Reestabilshment Request) generated by the RRC layer. In addition, Msg 3 may also carry, for example, a cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI) and the like.

又例如，对于切换场景，Msg 3可以包括RRC层生成的RRC切换确认消息(RRCHandover Confirm)，其携带终端设备的C-RNTI。此外，Msg 3还可携带例如缓冲状态报告(Buffer Status Report，BSR)等信息。对于其它触发事件例如上/下行数据到达的场景，Msg 3至少可以包括终端设备的C-RNTI。For another example, for the handover scenario, Msg 3 may include an RRC handover confirmation message (RRCHandover Confirm) generated by the RRC layer, which carries the C-RNTI of the terminal device. In addition, Msg 3 may also carry information such as a buffer status report (Buffer Status Report, BSR). For other trigger events such as the arrival of uplink/downlink data, Msg 3 may at least include the C-RNTI of the terminal device.

步骤4，网络设备向终端设备发送冲突解决消息(contention resolution)，即Msg4。Step 4, the network device sends a contention resolution message (contention resolution), namely Msg4, to the terminal device.

网络设备向终端设备发送Msg 4，终端设备正确接收Msg4完成竞争解决(Contention Resolution)。例如在RRC连接建立过程中，Msg 4中可以携带RRC连接建立消息。The network device sends Msg 4 to the terminal device, and the terminal device correctly receives Msg4 to complete contention resolution. For example, during the RRC connection establishment process, Msg 4 may carry the RRC connection establishment message.

由于步骤3中的终端设备可以在Msg 3中携带自己唯一的标识，从而网络设备在竞争解决机制中，会在Msg4中携带终端设备的唯一标识以指定竞争中胜出的终端设备。而其它没有在竞争解决中胜出的终端设备将重新发起随机接入。Since the terminal device in step 3 can carry its own unique identifier in Msg 3 , the network device will carry the unique identifier of the terminal device in Msg4 in the competition resolution mechanism to designate the winning terminal device in the competition. However, other terminal devices that do not win the contention resolution will re-initiate random access.

应理解，在本申请实施例中，竞争冲突解决可以有两种方式：It should be understood that in this embodiment of the application, there are two ways to resolve contention conflicts:

方式一、如果终端设备在Msg 3携带了C-RNTI，则Msg4可以用C-RNTI加扰的PDCCH调度。Mode 1: If the terminal device carries the C-RNTI in Msg3, then Msg4 can use the PDCCH scrambled by the C-RNTI for scheduling.

方式二、如果终端设备没有在Msg 3中携带C-RNTI，比如是初始接入，则Msg 4可以用TC-RNTI加扰的PDCCH调度。此时，竞争冲突的解决可以是通过终端设备接收Msg 4的PDSCH，获得冲突解决ID，通过匹配该冲突解决ID与Msg 3中中的公共控制信道(Commoncontrol channel，CCCH)服务数据单元(Service Data Unit，SDU)来判断是否解决冲突。Method 2: If the terminal equipment does not carry C-RNTI in Msg 3, for example, for initial access, Msg 4 may use the PDCCH scrambled by TC-RNTI for scheduling. At this time, the contention conflict can be resolved by receiving the PDSCH of Msg 4 through the terminal device, obtaining the conflict resolution ID, and matching the conflict resolution ID with the common control channel (Commoncontrol channel, CCCH) service data unit (Service Data Unit, SDU) to determine whether to resolve the conflict.

四步随机接入的时延比较大，对于5G中的低时延高可靠场景是不合适的。考虑到低时延高可靠相关业务的特点，提出了两步随机接入过程的方案。如图3所示，在两步随机接入过程中，简单的说，相当于将四步随机接入过程的第一步和第三步合并为两步随机接入过程中的第一步，将四步随机接入过程的第二步和第四步合并为两步随机接入过程中的第二步。The delay of four-step random access is relatively large, which is not suitable for low-latency and high-reliability scenarios in 5G. Considering the characteristics of low-latency and high-reliability related services, a two-step random access procedure is proposed. As shown in Figure 3, in the two-step random access process, simply speaking, it is equivalent to combining the first step and the third step of the four-step random access process into the first step of the two-step random access process, The second and fourth steps of the four-step random access procedure are combined into the second step of the two-step random access procedure.

更具体地，两步随机接入过程可以包括：More specifically, the two-step random access procedure may include:

第一步：终端设备向网络设备发送第一消息。Step 1: the terminal device sends a first message to the network device.

其中，第一消息可以由Preamble和有效负载(payload)组成，Preamble为四步随机接入的Preamble，该Preamble在PRACH资源上传输，Payload主要携带四步随机接入中的Msg3中的信息。例如，可以包含CCCH SDU，比如对应RRC空闲态下的随机接入，也可以包含C-RNTI MAC控制单元(Control Element，CE)，比如主要对应RRC连接态下的随机接入。Payload可以承载于上行信道，该信道例如可以为物理上行共享信道(Physical UplinkShared Channel，PUSCH)。Wherein, the first message may be composed of a Preamble and a payload (payload). The Preamble is a Preamble for four-step random access. The Preamble is transmitted on the PRACH resource. The Payload mainly carries information in Msg3 in the four-step random access. For example, it may contain CCCH SDU, such as corresponding to random access in RRC idle state, and may also contain a C-RNTI MAC control element (Control Element, CE), such as mainly corresponding to random access in RRC connected state. The Payload may be carried on an uplink channel, for example, the channel may be a Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH).

应理解，第一消息可以携带四步随机接入过程中的Preamble和Msg 3中携带的部分或全部信息。It should be understood that the first message may carry part or all of the information carried in the Preamble and Msg 3 in the four-step random access process.

第二步：网络设备向终端设备发送第二消息。Step 2: The network device sends a second message to the terminal device.

若网络设备成功接收到终端设备发送的第一消息，则可以向终端设备发送第二消息。该第二消息中可以包含四步随机接入过程中的Msg 2和Msg 4中携带的部分或全部信息。第一消息和第二消息的名称并不限定，也就是说，它们也可以表述为其他名称。例如，第一消息也可以称为Msg A、随机接入请求消息或新Msg 1，第二消息也可以称为Msg B、随机接入响应信息或新Msg 2。If the network device successfully receives the first message sent by the terminal device, it may send the second message to the terminal device. The second message may contain part or all of the information carried in Msg 2 and Msg 4 in the four-step random access process. The names of the first message and the second message are not limited, that is, they can also be expressed by other names. For example, the first message may also be called Msg A, a random access request message or new Msg 1, and the second message may also be called Msg B, random access response information or new Msg 2.

应理解，图3仅仅是两步随机接入过程的一种具体实现方式，不应对本申请的保护范围构成限定。It should be understood that FIG. 3 is only a specific implementation manner of the two-step random access process, and should not limit the protection scope of the present application.

然而，在两步随机接入过程中，处于空闲态或者去激活态的终端设备，在两步随机接入过程中没有C-RNTI信息，因此发送完Msg A后如何盲检Msg B是一个问题。在四步随机接入中，终端设备解码的是RA-RNTI加扰的PDCCH，即在四步随机接入中，网络设备使用RA-RNTI来调度Msg 4。如果网络设备仍使用RA-RNTI来调度Msg B，则对四步随机接入的终端设备来说，当终端设备检测到RA-RNTI加扰的PDCCH时，只有解码PDCCH调度的PDSCH(即payload)后才能区分是不是发给自己的RAR，从而增加了四步随机接入终端设备解码PDCCH而造成的开销。However, during the two-step random access process, the terminal equipment in the idle state or deactivated state has no C-RNTI information during the two-step random access process, so how to blindly detect Msg B after sending Msg A is a problem . In the four-step random access, what the terminal device decodes is the PDCCH scrambled by the RA-RNTI, that is, in the four-step random access, the network device uses the RA-RNTI to schedule Msg 4. If the network device still uses RA-RNTI to schedule Msg B, then for the terminal device with four-step random access, when the terminal device detects the PDCCH scrambled by RA-RNTI, it can only decode the PDSCH scheduled by PDCCH (that is, the payload) Only after the RAR can it be distinguished whether it is sent to itself, thereby increasing the overhead caused by the four-step random access terminal device decoding the PDCCH.

以下详细阐述本申请针对上述技术问题而设计的两步随机接入方案。The following describes in detail the two-step random access scheme designed by this application to address the above technical problems.
