本申请主张在2020年8月13日在中国提交的中国专利申请号No.202010814515.0的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种随机接入的信号传输方法、终端及网络侧设备。
背景技术
在工业无线传感器、视频监控和可穿戴设备等使用场景中，终端需要在接收天线、接收和发射天线的数目、支持的带宽、终端处理数据和信号的时间及能力等方面降低复杂度，称该类终端为能力简化终端(Redcued Capability UE，RedCap UE)，收发天线数目和支持带宽的减少影响到终端的覆盖能力。
随机接入(Random Access，RA)是蜂窝系统的一个基本功能，使终端和网络设备建立连接，随机接入过程是指终端发送随机接入前导码开始尝试接入网络设备到与网络设备建立基本的信令连接之前的过程，终端通过随机接入与网络设备进行信息交互，完成后续操作：如呼叫、资源请求、数据传输等。
目前，在Rel15/16协议定义的随机接入过程中，终端每次发送一个随机接入前导码，网络侧设备针对每个接到的随机接入前导码返回响应，即终端针对每个随机接入前导码在相应的接收窗口内接收对应的响应，由于RedCap终端的发送和接收能力相比于普通终端弱，需要多次发送随机接入前导码和接收响应消息，容易导致终端完成随机接入响应的延时增加。

在本申请实施例中，终端通过向网络侧发送N次第一信息，以提高随机接入成功的可能性，且接收窗口是在发送N次第一消息中的第n次发送第一消息后开启的，在接收窗口内接收网络设备发送的响应信息，即终端发送N次第一信息，在N次第一消息中的第n次发送第一消息后开启的接收窗口内接收网络设备发送的响应信息即可，响应信息是网络侧设备在终端N次第一消息中的第n次发送第一消息后对应的接收窗口内发送的，可减少网络侧设备发送的响应信息的次数，从而减少终端接收响应信息的次数，以增强对响应信息的接收性能，提高完成随机接入响应的效率。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的 描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(vehicle user equipment，VUE)、行人终端(pedestrian user equipment，PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(evolved Node B，eNB)、家用B节点、家用演进型B节点、无线局域网(wireless local area network，WLAN)接入点、无线保真(wireless fidelity，WiFi)节点、发送接收点(Transmitting Receiving Point，TRP)或领域中其他某个合适的术语，只要达到相同的技术效果，基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的随机接入的信号传输方法进行详细地说明。
如图2所示，本申请实施例提供一种随机接入的信号传输方法，应用于终端，包括：
步骤201：向网络设备发送N次第一消息，第一消息包括第一随机接入前导码，N为大于1的整数；
步骤202：在接收窗口内接收网络设备发送的响应信息，接收窗口是在发送N次第一消息中的第n次发送第一消息后开启的，n为整数，且1≤n≤N。
接收窗口可以理解为一个时间窗口，在接收窗口开启的情况下，终端才能接收网络侧设备针对接收的第一消息返回的响应信息。在随机接入过程中，终端向网络侧设备发送N次第一消息，第一消息包括第一随机接入前导码，然后在发送N次第一消息中的第n次发送第一消息后开启的接收窗口内接收网络设备发送的响应信息即可。需要说明的是，网络侧设备是在成功接收到第一消息的情况下，针对成功接收的第一消息中的一个第一消息返回响应信息。
在本申请实施例中，终端通过向网络侧发送N次第一信息，以提高随机接入成功的可能性，且接收窗口是在发送N次第一消息中的第n次发送第一消息后开启的，在接收窗口内接收网络设备发送的响应信息，即终端发送N次第一信息，在N次第一消息中的第n次发送第一消息后开启的接收窗口内接收网络设备发送的响应信息即可，响应信息是网络侧设备在终端N次第一消息中的第n次发送第一消息后对应的接收窗口内发送的，可减少网络侧设备发送的响应信息的次数，从而减少终端接收响应信息的次数，以增强对响应信息的接收性能，提高完成随机接入响应的效率。
作为一个示例，所述发送N次第一消息，每次发送的第一消息可以相同或不同，例如，可以是包括同一个随机接入前导码的第一消息多次重复发送，也可以是发送多个包括满足预设规则的不同随机接入前导码的第一消息。
作为一个示例，可以是在发送N次第一消息中每间隔发送s次第一消息后开启一次接收窗口，s为正整数，如此，接收窗口每间隔一定的时间开启一次，减少接收窗口开启的频次，提高响应信息的接收性能。
可选的，第一消息可以为第一随机接入前导码或者第一消息包括第一随机接入前导码和物理上行共享信道(physical uplink shared channel，PUSCH)承载数据。
NR(New Radio，新空口)支持两种类型的随机接入/访问过程：4步RA(Random Access，随机接入)类型(4-step RACH(Random Access Channel，随机接入信道))和2步RA类型。两种类型的RA过程都支持基于竞争的随机访问(Contention based Random Access，CBRA)和无竞争的随机访问(Contention free Random Access，CFRA)，4步RA类型的CBRA的过程如 图3，4步RA类型的CFRA的过程如图5所示，2步RA类型的CBRA的过程如图4所示，2步RA类型的CFRA的过程如图6所示。针对上述两种类型，终端在随机接入过程中，向网络侧发送的消息不同，例如，对于4步RA，终端向网络侧设备发送的第一消息为第一随机接入前导码，此时，第一消息可以为随机接入前导码(Random Access Preamble，RAP)，接收的响应信息包括随机接入响应(图3和5中的Random Access Response，即RAP)。对于2步RA，终端向网络侧设备发送的第一消息包括第一随机接入前导码以及物理上行共享信道PUSCH承载数据(即图4和图6中的PUSCH payload)，此时，第一消息可以为MSGA，对于2步RA类型的CFRA，接收的响应信息包括随机接入响应(图6中的Random Access Response)，对于2步RA类型的CBRA，接收的响应信息包括无线资源控制(Radio Resource Control，RRC)连接建立，终端接收后，完成竞争解决，即竞争消除(Contention Resolution)。需要说明的是，终端使用物理随机接入信道(Physical Random Access Channel，PRACH)向网络侧设备发送上述第一信息。
需要说明的是，1≤n≤N，即n可以小于N，也可以等于N，即接收窗口是在发送N次第一消息中的最后一次发送第一消息后开启的；或者，接收窗口是在发送N次第一消息中的不为最后一次发送第一消息后开启的。
可选的，若n等于N，则接收窗口的数量为一个，接收窗口是在发送N次第一消息中的最后一次发送第一消息后开启的。可以理解，终端可以在发送完N次第一消息后开启接收窗口，即开启一次接收窗口，接收窗口对应N个第一消息，终端在发送完毕N次第一消息后，开启接收窗口，在接收窗口内接收终端侧设备返回的响应信息。
可选的，接收窗口也可以是在发送N次第一消息中的不为最后一次发送第一消息后开启，即在N次第一消息发送完毕之前的某次发送第一消息之后开启接收窗口，以接收网络侧设备发送的响应信息。需要说明的是，若n小于N，开启的接收窗口的数量可以是一个或多个，对于多个的情况，可以理解，在发送N次第一消息过程中，间隔开启接收窗口，每个接收窗口对应于部分第一消息，如此，每间隔一定的时间开启一次接收窗口，减少接收窗口开启的频次，提高响应信息的接收性能。
如图7所示，UE表示终端，gNB表示网络侧设备，例如，可以是基站等。终端向网络侧设备发送第n次第一消息后开启接收窗口(图中虚线)，第1次到第n次的第一消息共享一个接收窗口，网路侧设备同样也开启响应窗口，网络侧设备在响应窗口内发送响应信息，终端在接收窗口内接收网络侧设备发送的响应信息，若根据响应信息确定第一消息发生成功，则进行第三步(step3)，向网络侧设备发送连接建立请求，网络设备接收该请求后返回确认，建立连接。
另外，可选的，终端在发送N次第一消息的过程中，若达到停止发送条件，可停止第一消息的发送，其中，停止发送条件可以包括第一消息的发送次数达到发送次数阈值，例如，发送次数阈值为N，则发送完N次第一消息后停止。和/或，停止发送条件也可以是终端接收到网络侧设备针对第一消息返回的响应信息，例如，在发送第n次第一消息后开启接收窗口，在接收窗口内成功接收到网络侧设备返回的响应信息，表示网络侧设备接收第一消息成功，可进行后续的交互，此时，终端可停止后续的第一消息的发送。需要说明的是，发送次数阈值可根据网络设备发送的高层信令配置确定或根据协议的规则确定。
可选的，若n小于N，接收窗口的开启时刻对应于在发送N次第一消息中的第n次发送第一消息结束后的首个第一类型搜索空间的起始正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的时刻。
第一类型搜索空间(Common Search Space，CSS)即Type1搜索空间，第一类型搜索空间可按照协议规定的间隔或终端与网络侧设备预先预定的间隔出现，可以理解，接收窗口的开启时刻为第n次发送第一消息结束后第一个第一类型搜索空间的起始OFDM符号的出现时刻，作为一个示例，接收窗口的时长不超过10毫秒。
可选的，n小于N，接收窗口的数量为多个，第j个接收窗口是在发送N次第一消息中的第n j次发送第一消息后开启的，第j个接收窗口对应于i j次第一消息，n j为第j-1个接收窗口对应的n j-1与i j之和，n 1为第1个接收窗口对应的i 1，i j次第一消息包括第n j次发送的第一消息以及距离第n j次发送的第一消息的时刻最近发送的i j-1次第一消息，i j为整数，且1≤i j≤n，1≤j≤N， 1≤n j≤N。
第1个接收窗口是在发送N次第一消息中的第n 1次发送第一消息后开启的，n 1即为i 1，多个接收窗口对应的第一消息的数量之和为N。每个接收窗口有对应的第一消息，例如，对于第j个接收窗口，对应的i j次第一消息包括第n j-i j+1次到第n j次发送的第一消息，i j可根据协议规定或根据网络侧设备配置确定，即这i j个第一消息对应相同的一个接收窗口，即第j个接收窗口。对于第n j-i j+1次之前发送的i j-1次第一消息，则对应前一个开启的接收窗口，即第j-1个接收窗口，第j-1个接收窗口是在发送N次第一消息中的第n j-1次发送第一消息后开启的，第j-1个接收窗口对应于i j-1次第一消息，n j-1为第j-2个接收窗口对应的n j-2与i j-1之和。例如，j为1时，对应第1个接收窗口，n 1为5，i 1为5，第n 1次(即第5次)发送第一消息后开启一个接收窗口，则该接收窗口对应第1次到第5次发送的5个第一消息，j为2时，对应第2个接收窗口，n 2为10，i 2为5，第n 2次(即第10次)发送第一消息后又开启一个接收窗口，则该接收窗口对应第6次到第10次发送的5个第一消息。
可选的，方法还包括：在第j个接收窗口对应的已发送的i j次第一消息中，包括第一随机前导码与第j个接收窗口中的响应信息中的指示信息匹配的第一消息的情况下，确定匹配的第一消息传输成功。
网络侧设备可针对一个接收窗口对应的第一消息，返回这些第一消息对应的响应信息，针对终端发送的对应同一个接收窗口的第一消息，网络侧设备成功接收至少一个第一消息后，可向终端返回响应信息，以表示有成功接收到第一消息，对响应信息中指示信息与该接收窗口对应的第一消息的第一随机前导码进行匹配，若在该接收窗口对应的第一消息中包括第一随机前导码与指示信息匹配的第一消息，则表示匹配的第一消息传输成功。即在本实施例中，在接收窗口内接收响应信息后，还需将其携带的指示信息与该接收窗口对应的第一消息的第一随机前导码进行匹配，若匹配到至少一个第一消息，则表示匹配的第一消息传输成功。
若终端为每次发送的RAR(PRACH)或MSGA维护一个RA-RNTI或者MSGB-RNTI以及接收窗口，RAR即Rach access response，为随机接入响应，通过判断RAR(4步RA的CBRA和CFRA中网络侧设备基于第一消息返回 的响应信息)或MSGB(2步RA的CBRA和CFRA中网络侧设备基于第一消息返回的响应信息)中承载的前导码与上述RA-RNTI或者MSGB-RNTI对应的RAR或MSGA的前导码是否匹配，来判断RAP或MSGA传输是否成功。若终端为一组RAP或MSGA维护一个RA-RNTI或者MSGB-RNTI以及接收窗口，通过判断RAR或MSGB中承载的前导码与上述RA-RNTI或者MSGB-RNTI对应的上述一组PRACH或MSGA的前导码是否匹配，来判断PRACH或MSGA传输是否成功。
需要说明的是，响应信息中的指示信息可以是一个随机接入前导码，为区分于第一消息中的第一随机接入前导码，响应信息中的指示信息可以第二随机接入前导码。
可选的，在接收窗口内接收网络设备发送的响应信息，包括：在接收窗口内，接收利用无线网络临时标识加扰的物理下行控制信道(physical downlink control channel，PDCCH)；利用PDCCH指示的物理下行共享信道(physical downlink shared channel，PDSCH)资源接收网络设备发送的响应信息。
终端在某一次发送第一消息之后开启接收窗口后，即可开始以检测Type1CSS PDCCH，在检测到利用无线网络临时标识加扰的物理下行控制信道PDCCH的情况下，即可利用PDCCH指示的PDSCH资源接收网络设备发送的响应信息。需要说明的是，对于4步RA和2步RA，分别有对应的无线网络临时标识，比如，对于4步RA，终端向网络侧设备发送第一随机前导码，无线网络临时标识为随机接入无线网络临时标识(即RA-RNTI,RNTI即Radio Network Temporary Identifier，无线网络临时标识)。对于2步RA，终端向网络侧设备发送第一随机前导码以及PUSCH承载数据，例如，第一随机前导码以及PUSCH承载数据称为MSGA信号，网络侧设备返回的响应信息可表示为MSGB，则无线网络临时标识为MSGB-RNTI。也就是说，上述无线网络临时标识可以为RA-RNTI或MSGB-RNTI。
可选的，在第j个接收窗口对应的已发送的i j次第一消息中，包括第一随机前导码与第j个接收窗口中的响应信息中的指示信息匹配的第一消息的情况下，确定匹配的第一消息传输成功，包括：
在第j个接收窗口内接收的响应信息中的指示信息与第j个接收窗口对应的已发送的i j次第一消息中目标消息的第一随机前导码匹配，则确定目标消息传输成功，其中，目标消息为i j次第一消息中与终端获得的无线网络临时标识对应的第一消息。
即在匹配过程中，利用无线网络临时标识对应的第一消息的第一随机前导码与在第j个接收窗口内接收的响应信息中指示信息进行匹配，若能匹配成功，则表示第j个接收窗口对应的i j次第一消息中无线网络临时标识对应的第一消息传输成功。即在本实施例中，无需将指示信息与i j次发送的第一消息的第一随机前导码逐一匹配，直接将指示信息与i j次第一消息中无线网络临时标识对应的第一消息进行匹配即可，提高匹配效率。
可选的，向网络设备发送第n j次第一消息之后，还包括：
根据协议规定或网络设备发送的第一指示信息指示的目标时频资源确定无线网络临时标识。
即终端可根据协议规定的目标时频资源来计算无线网络临时标识，也可以接收网络设备发送的第一指示信息计算无线网络临时标识，第一指示信息用于指示目标时频资源，即根据第一指示信息指示的目标时频资源计算无线网络临时标识。
可选的，根据协议规定或网络设备发送的第一指示信息指示的目标时频资源确定无线网络临时标识，包括：根据偏移参数以及目标时频资源确定无线网络临时标识。
即在本实施例中，终端可根据偏移参数和目标时频资源确定无线网络临时标识计算无线网络临时标识，保证N次第一消息对应的RNTI与Rel15/16协议中定义的RNTI不同，防止出现终端行为歧义。一种可能的方式，通过在计算RNTI计算公式中引入偏移参数，实现上述功能。偏移参数可以作用在RNTI计算公式中的已有的参数上或者作为固定的偏移尝试添加在RNTI计算公式中。另一种可能的方式，计算N次第一消息对应的N个RNTI，基于N个RNTI换算出RNTI，例如加权平均。
作为一个示例，偏移参数可以包括用于传输第一消息的PRACH的第一个OFDM符号的编号对应的第一偏移和用于传输第一消息的PRACH所在第 一个时隙的编号对应的第二偏移等。需要说明的是，偏移参数可预先设定。其中OffsetA和OffsetB大于或等于0，且至少有一个不为零，通过OffsetA或者OffsetB或者两者的组合来区分与普通RA-RNTI或者MSGB-RNTI的区别。通过OffsetA或者OffsetB或者两者的组合来确定RAP或者MSGA的重复发送或者重复接收的次数。OffsetA和/或OffsetB的数值可以与PRACH时域资源参数或者PRACH的传输格式相关联。一种可能的选择准则为，保证s_id+OffsetA或者t_id+OffsetB的所有取值与s_id或者t_id的所有可能取值不同；其中，s_id和t_id由PRACH的PRACH传输格式和传输时机的配置而确定，由系统信息配置。偏移参数可以根据系统信息显示配置，或者根据系统信息配置的PRACH传输格式和传输时机结合协议预定义的规则隐式确定。
作为一个示例，可通过以下公式计算无线网络临时标识：
RA-RNTI＝1+(s_id+OffsetA)+14×(t_id+OffsetB)+14×80×f_id+14×80×8×ul_carrier_id；
MSGB-RNTI＝1+(s_id+OffsetA)+14×(t_id+OffsetB)+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×2。
其中，s_id为用于传输第一消息的PRACH的第一个OFDM符号的编号，t_id为用于传输第一消息的PRACH所在第一个时隙的编号，OffsetA为第一偏移，OffsetB为第二偏移，f_id为用于传输第一消息的PRACH的频域编号，ul_carrier_id为表示传输第一消息的上行载波的类型的标识，例如，0表示NUL载波，1表示SUL载波。
可选的，目标时频资源包括以下任一项：
i j次第一消息中最早一次发送的第一消息的时频资源；
i j次第一消息中最近一次发送的第一消息的时频资源；
i j次第一消息中协议规定或第一指示信息指示的第一消息的随机接入信道时机。
需要说明的是，最早一次发送的第一消息的时频资源可以理解为在当前开启的接收窗口对应的第一消息中最早一次发送的第一消息的时频资源，不包括前一个接收窗口对应的最早一次发送的第一消息。
对于多次第一消息传输具有专用的前导码(preamble)与随机接入信道时 机(RACH occasion，RO)的对应关系(包含preamble的选择，每次第一消息传输的RO选择)，由协议规定或者系统通知。以多次第一消息传输中的某一次第一消息的RO作为参考点计算的RA-RNTI或者MSGB-RNTI，以代表多次第一消息传输。
可选的，确定第一消息传输成功之后，还包括：根据响应信息中的指示信息或/和无线网络临时标识，确定与响应信息满足准共址关系的参考信号，参考信号包括同步信号块SSB或网络配置的参考信号。
在确定匹配的第一消息传递成功后，需要确定网络侧设备成功接收第一消息的参考信号，即需要确定与响应信息满足准共址(Quasi co-location，QCL)关系的目标同步信号块(Synchronization Signal and PBCH block，SSB)或与响应信息满足准共址关系的网络配置的参考信号。作为一个示例，后续终端向网络侧设备发送信号的过程中，可采用目标SSB向网络侧设备发送，以提高传输可靠性。
可选的，确定与响应信息满足准共址关系的参考信号，包括以下任一项：
在无线网络临时标识关联的第一消息与同一个参考信号对应的情况下，确定响应信息与同一个参考信号满足准共址关系；
在无线网络临时标识关联的第一消息与多个参考信号对应的情况下，根据指示信息或无线网络临时标识，以及多个参考信号对应的第一消息的第一随机接入前导码，确定与响应信息满足准共址的参考信号；
根据网络设备发送的第二指示信息，确定与响应信息满足准共址关系的参考信号，其中，第二指示信息承载在利用无线网络临时标识加扰的PDCCH或响应信息中。
可选地，述确定与响应信息满足准共址关系的参考信号之后，还包括：终端基于上述准共址关系向网络侧设备发送第二消息。例如，第二消息可以包括图3中的Contention Resolution(连接建立请求)，该第二信息可以用MSG3消息表示。
可选地，响应信息还指示了重复次数m，重复次数m指示了网络设备检测m个第一消息后成功检测到第一消息。进一步可选地，终端可向网络侧设备重复发送m次MSG3消息，已提高网络测设备接收MSG3消息的成功率。
如果RA-RNTI或MSGB-RNTI关联的K个RAP或MSGA，上述K个RAP或MSGA属于关联于同一个SSB，或者关联于PDCCH命令触发的K个RAP或MSGA，那么RAR或MSGB消息与上述SSB或者上述PDCCH的解调参考信号(Demodulation Reference Signal，DMRS)满足QCL关系。
如果RA-RNTI或MSGB-RNTI关联的K个RAP或MSGA，上述K个RAP或MSGA属于关联于多个SSB，不同SSB相关联的RAP或MSGA消息使用preamble不同，由Random Access Preamble identifier(前导码索引)与多个候选preamble的对应关系判断RAR或MSGB消息与SSB的QCL关联关系。
在RA-RNTI或MSGB-RNTI加扰的下行控制信息(Downlink Control Information，DCI)或者RAR或MSGB中增加若干比特指示，在K次传输的第k次完成RAP或MSGA消息接收，随机接入响应(Rach access response，RAR)或MSGB与第k次RAP或MSGA消息对应的SSB满足QCL关系。
可选的，N次第一消息关联P个不同的第一SSB，P为整数，每个第一消息关联一个第一SSB；
向网络设备发送N次第一消息，包括：
根据SSB与随机接入信道时机的对应关系，以及每个第一消息关联的第一SSB，确定N次第一消息中每个第一消息的第一随机接入信道时机；
根据第一消息的第一随机接入信道时机向网络设备发送第一消息。
N次第一消息关联于M(M>＝1)个不同的SSB，并且按照SSB与RACH时机(RO)的对应关系，在相应的RO上发送第一消息。M个SSB的选择方式由协议预定规则确定，例如，可根据SSB信号接收能量强度进行选择。上述M个SSB中某一个SSB对应的第一消息的发送次数L由协议预定规则确定，M个SSB对应的发送次数的总和为N。
可选的，N次第一消息的第一随机接入信道时机被配置在一个或连续多个物理随机接入信道时机上。
对应于每一次第一消息的传输，对应于网络侧设备对第一消息采用单次检测的方式，由于当一次第一消息接收成功后，开启RAR接收窗口至少要等到Type1CSS出现的时隙，至少是下一个时隙。在当前时隙内如果再次发送 另一个第一消息，那么两个第一消息的RAR接收窗口重合。多次发送的PRACH RO被配置在一个或连续几个时隙上，对应于相同的RAR/MSGB接收窗口开启时间。上述连续几个时隙中间不会出现Type1CSS。
对应于N次第一消息传输中的K次传输，例如某一个SSB对应的第一消息的L次传输结束后，又例如一个或多个时隙内的第一消息传输接入后，例如按照Type1-CSS周期确定时隙数量，又例如按照RAR配置窗口大小确定时隙数量使RAR窗口不重叠，对应于网络侧设备对第一消息采用联合检测，例如基站对多个RO的上行信号合并后检测。网络侧设备的RAR接收窗口的开启方式由协议规定或者通过系统消息或者高层消息进行指示。可选地，RAR接收窗口的开启方式与网络侧设备对第一消息检测行为(合并检测或者独立检测)相关联
可选地，前一个接收窗口结束之前后一个接收窗口开启(即window overlapping，窗口重叠)，并且两者计算的无线网络临时标识相同(基于相同的参考RO计算得出)，则两个接收窗口合并为一个接收窗口，以后一个接收窗口的结束时间作为合并后的接收窗口的结束时间。
可选的，在接收窗口内接收网络设备发送的响应信息，包括：
在接收窗口内接收网络设备发送的多次响应信息。
为提高终端接收响应信息的成功率，网络侧设备可发送多次响应信息，终端在接收窗口内多次重复接收响应信息，终端重复接收的次数可由协议定义或者高层配置或者PDCCH指示，或者由SSB相关联的第一消息的发送次数决定。
例如，可根据RA-RNTI或者MSGB-RNTI确定RAR/MSGB的重复次数，例如一个SSB对应的L次RAP发送，对应于K个RA-RNTI或者MSGB-RNTI，第一个RA-RNTI对应于一次RAR/MSGB传输，网路侧设备在前L/K次传输中检测到RAP或者MSGA则使用第一个RA-RNTI发送一次RAR/MSGB。类似的，如果在第二组L/K个RA-RNTI中检测到RAP或者MSGA，使用第二个RA-RNTI进行两次RAR/MSGB重复传输。
另外，可选的，在FR2下，若RA-RNTI或MSGB-RNTI关联的K个RAP或MSGA，上述K个RAP或MSGA属于关联于多个SSB，按照上述多个 时隙中SSB关联的RO出现顺序，以时分的方式依次在不同时隙上的Type-1CSS上发送RA-RNTI或MSGB-RNTI加扰的PDCCH(即对应DCI)，满足与相应SSB准共址，终端按照相应的规则，使用与相应SSB相匹配的接收波束检测RA-RNTI或MSGB-RNTI加扰的PDCCH。可选地，接收窗口的时长可相应的进行放大。
