As communications technology evolves, the name "network equipment" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned apparatuses for providing a wireless communication function for the terminal 10 are collectively referred to as network devices.

本公开实施例中的“5G NR***”也可以称为5G***或者NR***，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR***，也可以适用于5G NR***后续的演进***。The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present disclosure may be applicable to the 5G NR system, and may also be applicable to the subsequent evolution system of the 5G NR system.

在NR中，主要支持两种随机接入方式，分别为4步随机接入方式，如图2所示；以及2步随机接入方式。In NR, two random access methods are mainly supported, namely, a 4-step random access method, as shown in Figure 2; and a 2-step random access method.

对于图2所示的随机接入过程分为4步。详细的步骤如下：The random access procedure shown in FIG. 2 is divided into four steps. The detailed steps are as follows:

1、终端向网络设备发送Msg1(Message 1，消息1)。1. The terminal sends Msg1 (Message 1, message 1) to the network device.

终端选择PRACH(Physical Random Access Channel，物理随机接入信道)资源，并在选择的PRACH上发送选择的preamble(前导码)。如果是基于非竞争的随机接入，PRACH资源和preamble可以由网络设备指定。网络设备基于preamble可以估计上行Timing(定时)，和终端传输Msg3(Message 3，消息3)所需要的grant(调度)大小。The terminal selects a PRACH (Physical Random Access Channel, physical random access channel) resource, and sends the selected preamble (preamble) on the selected PRACH. In the case of non-contention-based random access, the PRACH resource and preamble can be specified by the network device. Based on the preamble, the network device can estimate the uplink Timing (timing) and the grant (scheduling) size required by the terminal to transmit Msg3 (Message 3, Message 3).

2、网络设备发送RAR(Random Access Response，随机接入响应)给终端。2. The network device sends an RAR (Random Access Response, random access response) to the terminal.

终端发送Msg1之后，开启一个随机接入响应时间窗，在该随机接入响应时间窗内监测RA-RNTI(Random Access Radio Network Temporary Identifier，随机接入无线网络临时标识)加扰的PDCCH(Physical Downlink Control Channel，物理下行控制信道)。RA-RNTI的计算如下：After the terminal sends Msg1, a random access response time window is opened, and the PDCCH (Physical Downlink) scrambled by RA-RNTI (Random Access Radio Network Temporary Identifier, random access wireless network temporary identifier) is monitored within the random access response time window. Control Channel, physical downlink control channel). RA-RNTI is calculated as follows:

RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id；RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id;

即RA-RNTI跟UE发送Msg1所使用的PRACH时频资源有关。That is, the RA-RNTI is related to the PRACH time-frequency resource used by the UE to send the Msg1.

终端成功接收到RA-RNTI加扰的PDCCH之后，终端能够获得该PDCCH调度的PDSCH，其中包含了RAR(随机接入相应)，RAR具体包含以下信息：After the terminal successfully receives the PDCCH scrambled by the RA-RNTI, the terminal can obtain the PDSCH scheduled by the PDCCH, which includes the RAR (random access response), and the RAR specifically includes the following information:

RAR的subheader(包头)中包含BI，用于指示重传Msg1的回退时间；The subheader (packet header) of RAR contains BI, which is used to indicate the fallback time of retransmission of Msg1;

RAR中的RAPID：网络设备响应收到的preamble index(前导码指示)；RAPID in RAR: The network device responds to the received preamble index (preamble indication);

RAR的payload(载荷)中包含了TAG，用于调整上行定时；The payload of RAR contains TAG, which is used to adjust the uplink timing;

UL grant(Uplink grant，上行调度)：用于调度Msg3的上行资源指示；UL grant (Uplink grant, uplink scheduling): used to schedule the uplink resource indication of Msg3;

Temporary C-RNTI(Temporary Cell Radio Network Temporary Identifier，临时小区无线网络临时标识)：用于加扰Msg4的PDCCH(初始接入)。Temporary C-RNTI (Temporary Cell Radio Network Temporary Identifier, Temporary Cell Radio Network Temporary Identifier): used to scramble the PDCCH (initial access) of Msg4.

如果终端接收到RAR-RNTI(Random Access Response Radio Network Temporary Identifier，随机接入响应无线网络临时标识)加扰的PDCCH，并且RAR中包含了自己发送的preamble index，则终端认为成功接收了随机接入响应。If the terminal receives the PDCCH scrambled by RAR-RNTI (Random Access Response Radio Network Temporary Identifier, random access response wireless network temporary identifier), and the RAR contains the preamble index sent by itself, the terminal considers that the random access has been successfully received. response.

对于基于非竞争的随机接入，终端成功接收Msg2(Message 2，消息2)后，随机接入过程结束。对于基于竞争的随机接入，终端成功接收Msg2后，还需要继续传输Msg3和接收Msg4(Message 4，消息4)。For non-contention-based random access, after the terminal successfully receives Msg2 (Message 2, Message 2), the random access process ends. For contention-based random access, after the terminal successfully receives Msg2, it needs to continue to transmit Msg3 and receive Msg4 (Message 4, message 4).

3、终端在网络设备调度资源上传输Msg3。3. The terminal transmits the Msg3 on the network equipment scheduling resource.

Msg3主要用于通知网络设备该RACH(Random Access Channel，随机接入信道)过程是由什么事件触发。比如，如果是初始接入随机过程，则在Msg3中会携带UE标识和establishment cause(建立原因)；如果是RRC重建，则会携带连接态UE标识和establishment cause。Msg3 is mainly used to notify the network device what event triggers the RACH (Random Access Channel, random access channel) process. For example, if it is an initial access random process, the UE identity and establishment cause (establishment cause) will be carried in Msg3; if it is RRC reestablishment, the connected UE identity and establishment cause will be carried.

4、网络设备向终端发送Msg4。4. The network device sends Msg4 to the terminal.

Msg4有两个作用，一个是用于竞争冲突解决，第二是网络设备向终端传输RRC配置消息。竞争冲突解决有以下两种方式：一种是如果UE在Msg3中携带了C-RNTI(Cell Radio Network Temporary Identifier，小区无线网络临时标识)，则Msg4用C-RNTI加扰的PDCCH调度。另一种是如果UE在Msg3中没有携带C-RNTI，比如是初始接入，则Msg4用TC-RNTI(Temporary Cell Radio Network Temporary Identifier，临时小区无线网络临时标识)加扰的PDCCH调度,冲突的解决是UE接收Msg4的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)，通过匹配PDSCH中的CCCH SDU(通用控制信道服务数据单元)。Msg4 has two functions, one is for contention conflict resolution, and the other is for the network device to transmit an RRC configuration message to the terminal. There are two ways to resolve contention conflicts: one is that if the UE carries a C-RNTI (Cell Radio Network Temporary Identifier, cell wireless network temporary identifier) in Msg3, then Msg4 is scheduled with a PDCCH scrambled by C-RNTI. The other is that if the UE does not carry C-RNTI in Msg3, such as initial access, Msg4 uses TC-RNTI (Temporary Cell Radio Network Temporary Identifier, temporary cell radio network temporary identifier) scrambled PDCCH scheduling, conflicting The solution is that the UE receives the PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) of Msg4, and matches the CCCH SDU (Common Control Channel Service Data Unit) in the PDSCH.

相比于图2，两步随机接入方式可以提高时延，同时也能降低信令开销。在两步随机接入方式中，msgA用于传输四步随机接入方式的msg1+msg3，msgB用于传输四步随机接入方式的msg2+msg4。Compared with Fig. 2, the two-step random access method can improve the delay and reduce the signaling overhead at the same time. In the two-step random access method, msgA is used to transmit msg1+msg3 of the four-step random access method, and msgB is used to transmit the msg2+msg4 of the four-step random access method.

相关技术中的无线资源控制释放(RRCrelease)消息中没有配置RACH资源。但是本申请实施例中，希望在RRCrelease消息中引入RACH资源的配置，比如为网络切片(Slice)引入RACH资源的配置。此时，UE存在选择SIB中配置的RACH资源，还是专用(dedicated)RRC中的RACH资源的问题。因此，提供有如下实施例：No RACH resource is configured in a radio resource control release (RRC release) message in the related art. However, in the embodiment of the present application, it is desirable to introduce the configuration of the RACH resource in the RRCrelease message, for example, the configuration of the RACH resource for the network slice (Slice). At this time, the UE has a problem of selecting the RACH resource configured in the SIB or the RACH resource in the dedicated (dedicated) RRC. Accordingly, the following examples are provided:

本步骤可参考图8所示的步骤468内容，不再赘述。For this step, reference may be made to the content of step 468 shown in FIG. 8 , which will not be repeated.

综上所述，本实施例提供的方法，在同时存在至少两组RACH配置参数的情况下，终端根据切片信息或对切片的支持，使用至少两组RACH配置参数中的一组RACH配置参数进行随机接入过程，使得终端能够更好地利用适合自身的RACH资源来进行随机接入过程，减少随机接入过程的耗时或提高随机接入过程的成功率。To sum up, in the method provided by this embodiment, when there are at least two sets of RACH configuration parameters at the same time, the terminal uses a set of RACH configuration parameters from the at least two sets of RACH configuration parameters according to slice information or slice support. The random access process enables the terminal to better utilize the RACH resources suitable for itself to perform the random access process, thereby reducing the time-consuming of the random access process or improving the success rate of the random access process.

在基于上述图4或图5或图6或图7或图8或图9的可选实施例中，终端在不同小区的随机接入行为是相同的，或者不同的。具体的，在不同的小区使用相同的行为执行随机接入过程，行为包括使用第一RACH信息和/或第二RACH信息的行为；或，在不同的小区使用不同的行为执行随机接入过程，行为包括使用第一RACH信息和/或第二RACH信息的行为。In the optional embodiment based on the above-mentioned FIG. 4 or FIG. 5 or FIG. 6 or FIG. 7 or FIG. 8 or FIG. 9 , the random access behaviors of the terminal in different cells are the same or different. Specifically, the same behavior is used to perform the random access procedure in different cells, and the behavior includes the behavior of using the first RACH information and/or the second RACH information; or, the random access process is performed using different behaviors in different cells, Actions include actions using the first RACH information and/or the second RACH information.

比如，终端在移动到第二小区范围内，或终端被切换/重定向/小区选择/小区重选到第二小区时，终端在第二小区执行随机接入过程。For example, when the terminal moves into the range of the second cell, or when the terminal is handed over/redirected/cell selection/cell reselection to the second cell, the terminal performs a random access procedure in the second cell.

示意性的，终端使用与第一小区相同的行为，在第二小区执行随机接入过程；或，终端使用与第一小区不同的行为，在第二小区执行随机接入过程。其中，随机接入过程中的行为包括：使用第一RACH信息和/或第二RACH信息的行为。Illustratively, the terminal uses the same behavior as the first cell to perform a random access procedure in the second cell; or, the terminal uses a different behavior from the first cell to perform the random access procedure in the second cell. Wherein, the behavior in the random access process includes: the behavior of using the first RACH information and/or the second RACH information.

比如，在第一小区范围内，终端按照第二RACH信息执行相关行为。当终端移动到第二小区范围内，终端按照第一RACH信息执行相关行为。For example, within the scope of the first cell, the terminal performs related actions according to the second RACH information. When the terminal moves into the range of the second cell, the terminal performs related actions according to the first RACH information.

比如，在第二小区范围内，终端忽略专有信令中的第二RACH信息，和/或，认为SIB中的第一RACH信息的优先级高。例如，当专有信令为RRC释放消息时，终端认为专有信令中的信息优先级高。For example, within the scope of the second cell, the terminal ignores the second RACH information in the dedicated signaling, and/or considers that the first RACH information in the SIB has a high priority. For example, when the dedicated signaling is an RRC release message, the terminal considers that the information in the dedicated signaling has a high priority.

比如，终端忽略SIB中的第一RACH信息，和/或，认为专有信令中的第二RACH信息的优先级高，和/或，应用专有信令中的第二RACH信息，和/或，应用SIB中的其他RACH指示(例如选择门限，选择指示，选择条件等)。For example, the terminal ignores the first RACH information in the SIB, and/or considers that the second RACH information in the dedicated signaling has a high priority, and/or applies the second RACH information in the dedicated signaling, and/or Or, apply other RACH indications in the SIB (eg selection threshold, selection indication, selection condition, etc.).

若不满足第二RACH信息的有效时间和/或有效范围条件，终端忽略专有信令中的第二RACH信息(或者，删除专有信令中的第二RACH信息)，认为SIB中的第一RACH信息的优先级高，和/或，应用SIB中的第一RACH信息。If the valid time and/or valid range conditions of the second RACH information are not met, the terminal ignores the second RACH information in the dedicated signaling (or deletes the second RACH information in the dedicated signaling), and considers the second RACH information in the SIB A RACH message has a high priority, and/or the first RACH message in the SIB is applied.

若满足第二RACH信息的有效时间和/或有效范围条件，UE认为专有信令中的第二RACH信息优先级高，和/或，应用专有信令中的第二RACH信息。If the valid time and/or valid range conditions of the second RACH information are satisfied, the UE considers that the second RACH information in the dedicated signaling has a high priority, and/or applies the second RACH information in the dedicated signaling.

比如，网络指示终端优先使用SIB，则终端选择SIB中的第一RACH信息，执行随机接入过程。For example, if the network instructs the terminal to preferentially use the SIB, the terminal selects the first RACH information in the SIB and performs the random access procedure.

比如，终端读取第二小区的SIB中的第一RACH信息，按照第一RACH信息在第二小区进行随机接入过程。终端可以先读取两种RACH信息，再判断使用第一RACH信息或第二RACH信息；终端也可以在判断结果为第二RACH信息无效的情况下再读取第一RACH信息；终端还可以在需要使用第一RACH信息时读取。For example, the terminal reads the first RACH information in the SIB of the second cell, and performs a random access procedure in the second cell according to the first RACH information. The terminal can read two kinds of RACH information first, and then judge to use the first RACH information or the second RACH information; the terminal can also read the first RACH information when the judgment result is that the second RACH information is invalid; Read when the first RACH message needs to be used.

比如，终端在第一时间内按照第一小区的专有RRC的第二RACH信息，执行随机接入过程；终端在第二时间内按照第二小区的SIB的第一RACH信息，执行随机接入过程。For example, the terminal performs random access according to the second RACH information of the dedicated RRC of the first cell within the first time; the terminal performs random access according to the first RACH information of the SIB of the second cell within the second time process.

需要说明的是，上述各个方法实施例可以根据本领域技术人员的理解，再拆分或组合为其它实施例。本申请不再一一赘述。It should be noted that, the above method embodiments can be divided or combined into other embodiments according to the understanding of those skilled in the art. This application will not repeat them one by one.

若配置了基于逻辑信道的优先级，当有动态授权和至少一个配置授权冲突时，且发生冲突的动态授权和配置授权的资源相同，或者发生冲突的动态授权和配置授权的资源中的最高逻辑优先级的逻辑信道的优先级相同，则优先动态授权或认为动态授权为优先的授权。If priority based on logical channel is configured, when there is a conflict between dynamic authorization and at least one configuration authorization, and the conflicting dynamic authorization and configuration authorization are the same resources, or the highest logic among the conflicting dynamic authorization and configuration authorization resources If the priorities of the logical channels with the same priority are the same, the dynamic authorization is given priority or the dynamic authorization is regarded as the priority authorization.

当有动态授权和至少一个配置授权冲突时，且发生冲突的动态授权和配置授权的资源优先级中的最高逻辑的最高优先级相同，则取决于UE实现来优先其中一个授权、或认为动态授权为优先的授权、或优先配置授权、或优先配置授权为优先的授权。When there is a conflict between a dynamic authorization and at least one configuration authorization, and the conflicting dynamic authorization is the same as the highest logical highest priority in the resource priority of the configuration authorization, then it depends on the UE implementation to prioritize one of the authorizations, or consider the dynamic authorization For the priority authorization, or the priority configuration authorization, or the priority configuration authorization as the priority authorization.
