相关申请的交叉引用
本申请要求在2021年05月10日提交中国专利局、申请号为202110506605.8、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在初始接入阶段，网络设备配置一个小区公共的带宽部分(bandwidth part，BWP)，其中，包括初始下行BWP(initial DL BWP)和初始上行BWP(initial UL BWP)。其中，随机接入过程中的一些上行信道传输参数在初始上行BWP配置，例如，随机接入过程中的第三消息(Msg3)的传输在初始上行BWP内进行。网络设备可以通过随机接入响应中的上行链路授权(RAR UL grant)调度随机接入过程中的一些上行信道。
由于初始上行BWP的最大带宽不能超过终端设备支持的最大带宽，传统(legacy)终端设备的初始上行BWP的频域范围和比传统终端设备的能力低的终端设备的初始上行BWP的频域范围不同，因此网络设备在不确定终端设备的类型的情况下，调度随机接入过程中的一些上行信道时容易出现传输错误。
发明内容
本申请提供一种通信方法及装置，可以解决网络设备在不确定或者未获得终端设备的类型的情况下，调度随机接入过程中的一些上行信道时出现传输错误的问题。
第一方面，本申请提供一种通信方法，该方法的执行主体可以是网络设备，也可以是芯片或电路。方法包括：向第一终端设备发送第一初始上行BWP的配置信息，以及向第二终端设备发送第二初始上行BWP的配置信息，其中，第一终端设备属于第一类终端设备，第二终端设备属于第二类终端设备。向第一终端设备发送第一信息，和/或，向第二终端设备发送第一信息，其中，第一信息指示的第一频域资源在第一初始上行BWP的频域范围内，第一频域资源用于第一终端设备发送Msg3，第一信息指示的第二频域资源在第二初始上行BWP的频域范围内，第二频域资源用于第二终端设备发送Msg3。
本申请实施例中网络设备调度Msg3时可以针对两类终端设备发送相同的调度信息(即第一信息)，该调度信息可以指示第一终端设备在第一终端设备的初始上行BWP(即第一初始上行BWP)范围内进行Msg3传输，并且该调度信息可以指示第二终端设备在第二终端设备的初始上行BWP(即第二初始上行BWP)范围内进行Msg3传输。通过上述方式，网络设备在不确定终端设备的类型的情况下，可以通过相同的指示值调度不同BWP范围的终端设备进行Msg3传输，从而可以避免由于Msg3的调度资源不在终端设备的初始上行BWP范围内导致的传输错误。
在一种可能的设计中，第一信息为资源指示值(RIV)。所述资源指示值是指频域资源的资源指示值。通过上述设计，网络设备可以针对两类终端设备指示相同的RIV。
在一种可能的设计中，在向第一终端设备发送第一信息之后，在第一频域资源接收来自第一终端设备的Msg3；和/或，在向第二终端设备发送第一信息之后，在第二频域资源接收来自第二终端设备的Msg3。通过上述设计，网络设备可以通过同一个信息(第一信息)指示两个终端设备在各自初始上行BWP范围内的频域资源，从而终端设备可以在对应的频域资源上发送Msg3，进而可以提高Msg3传输的成功率。
在一种可能的设计中，针对第二终端设备，基于第二频域资源的起始位置、长度以及第一初始上行BWP确定第一信息。通过上述设计，网络设备针对第一终端设备和第二终端设备均可以根据第一初始上行BWP确定第一信息，从而可以降低复杂度，使网络设备在不确定终端设备类型情况下，可以采用相同的规则确定Msg3传输的频域资源分配信息，从而可以解决可能出现的传输错误。
在一种可能的设计中，针对第一终端设备，基于第一频域资源的起始位置、长度以及第二初始上行BWP确定第一信息。通过上述设计，网络设备针对第一终端设备和第二终端设备均可以根据第二初始上行BWP确定第一信息，从而可以降低复杂度，使网络设备在不确定终端设备类型情况下，可以采用相同的规则确定Msg3传输的频域资源分配信息，从而可以解决可能出现的传输错误。

在一种可能的设计中，第一频域资源的起始位置和第二频域资源的起始位置相同。第一频域资源的起始位置为第一频域资源在第一初始上行BWP内的相对频域位置，第二频域资源的起始位置根据第二频域资源在第二初始上行BWP的相对频域位置以及第一偏移值确定的，第一偏移值为所述第一初始上行BWP的起始位置与所述第二初始上行BWP 的起始位置之间的频域偏移值。
通过上述设计，第一频域资源的起始位置和第二频域资源的起始位置相同，也就是第一频域资源在第一初始上行BWP内的相对频域位置与第二频域资源在第二初始上行BWP内的相对频域位置相同，并且根据第二初始上行BWP的起始位置与第一初始上行BWP的起始位置之间的频域偏移值可以实现在第一初始上行BWP的起始位置与第二初始上行BWP的起始位置不对齐的情况下，使得第一频域资源的绝对频域位置和第二频域资源的绝对频域位置相同。
在一种可能的设计中，第一频域资源的频域范围和第二频域资源的频域范围不同。通过上述设计，第一终端设备和第二终端设备可以根据同一个信息(第一信息)确定出各自初始上行BWP范围内的频域资源用于发送Msg3。
在一种可能的设计中，第一频域资源和/或第二频域资源属于第一频域资源集合，第一频域资源集合中任一频域资源对于第一终端设备的RIV和对于第二终端设备的RIV相同。上述设计中，网络设备通过在第一频域资源集合中为第一终端设备和第二终端设备分配Msg3的频域资源，使得网络设备可以通过一个信息(第一信息)分别指示两个终端设备的频域资源。
在一种可能的设计中，第一频域资源和第二频域资源属于第二频域资源集合中的第一频域资源子集合，第二频域资源集合中的至少一个频域资源子集合包括至少一个第一类频域资源和至少一个第二类频域资源，其中，在同一个频域资源子集合内，第一类频域资源对于第一终端设备的RIV和第二类频域资源对于第二终端设备的RIV相同。上述设计中，网络设备通过在第二频域资源集合中为第一终端设备和第二终端设备分配Msg3的频域资源，使得网络设备可以通过一个信息(第一信息)分别指示两个终端设备的频域资源。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备，可以为具有无线收发功能的设备或可设置于任一设备中的芯片，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、视频监控中的无线终端以及可穿戴终端设备等。
网络设备，可以为用于实现接入网设备的功能的装置，接入网设备可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，例如可以是NR系统中的下一代基站(next Generation node B，gNB)，可以是LTE系统中的演进型基站(evolutional node B，eNB)等。网络设备，也可以为能够支持网络设备实现该接入网设备功能的装置，例如芯 片系统，该装置可以被安装在网络设备中。
2)本申请实施例中的终端设备可以为第一类终端设备或第二类终端设备，或者其他需要进行传输性能增强的终端设备，如NR增强型移动宽带(Enhanced Mobile Broadband，eMBB)终端设备等。第一类终端设备和第二类终端设备之间的区别包括如下至少一项：
1.带宽能力不同。第一类终端设备支持的最大带宽可以大于第二类终端设备支持的最大带宽。例如，第一类终端设备最大可以支持在一个载波上同时使用100MHz频域资源和网络设备进行通信，而第二类终端设备最大可以支持在一个载波上同时使用20MHz或者10MHz或者5MHz频域资源和网络设备进行通信。
2.收发天线个数不同。第一类终端设备的天线配置可以大于第二类终端设备的天线配置。例如，第一类终端设备支持的最小天线配置可以大于第二类终端设备支持的最大天线配置。
3.上行最大发射功率不同。第一类终端设备的上行最大发射功率可以大于第二类终端设备的上行最大发射功率。
4.第一类终端设备与第二类终端设备对应的协议版本不同。例如NR Rel-15、NR Rel-16终端设备可以认为是第一类终端设备，第二类终端设备可以认为是NR Rel-17终端设备。
5.第一类终端设备与第二类终端设备支持的载波聚合(carrier aggregation，CA)能力不同。例如，第一类终端设备可以支持载波聚合，而第二类终端设备不支持载波聚合；又例如，第二类终端设备与第一类终端设备都支持载波聚合，但是第一类终端设备同时支持的载波聚合的最大个数大于第二类终端设备同时支持的载波聚合的最大个数。
6.第一类终端设备与第二类终端设备的频分双工(frequency division duplex，FDD)能力不同。例如，第一类终端设备可以支持全双工FDD，而第二类终端设备可以仅支持半双工FDD。
7.第二类终端设备和第一类终端设备对数据的处理时间能力不同，例如，第一类终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延小于第二类终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延。
8.第一类终端设备与第二类终端设备对应的上行和/或下行，传输峰值速率不同。
3)资源指示值(resource indication value,RIV)：用于分配传输资源的字段，例如对于Msg3，Msg3通过PUSCH进行传输，其初传调度信息通过第二消息(Msg2)中携带的随机接入响应(random access response,RAR)中的上行调度授权(uplink grant,UL grant)指示，RAR中的UL grant可以简称为RAR grant。RAR grant中包括物理上行共享信道(physical uplink shared channel，PUSCH)频域资源指示(PUSCH frequency resource allocation)域，该PUSCH frequency resource allocation域可以指示Msg3的频域资源分配。该PUSCH frequency resource allocation域可以包括一个与起始资源和连续分配的资源块的长度相应的RIV，在本申请中资源块的长度可以为资源单元的数量。
本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一 项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一频域资源和第二频域资源，只是为了区分不同的频域资源，而并不是表示这两个频域资源的大小、位置、优先级或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
随机接入过程包括4步随机接入信道(random access channel，RACH)和2步RACH。在4步RACH中网络设备在接收到终端设备发送的随机接入前导码(random access preamble)之后，向终端设备发送随机接入响应(random access response，RAR)，其中包括上行资源分配信息等信息。终端设备基于RAR消息的调度进行发送随机接入过程中的第三消息(Msg 3)，Msg3用于发送RRC建立连接请求。在2步RACH中，终端设备向网络设备发送消息A(MsgA)，MsgA包括两部分，一部分是preamble，另一部分是PUSCH载荷(payload)。MsgA消息，可以认为包括preamble和4步RACH中的Msg3所包括的内容。
目前，在初始接入阶段，网络设备配置一个小区公共的BWP用于终端设备进行随机接入，包括初始下行BWP(initial DL BWP)和初始上行BWP(initial UL BWP)。其中，随机接入过程中的一些上行信道传输参数在初始上行BWP配置，包括第一消息(Msg1)的物理随机接入信道(physical random access channel，PRACH)资源、Msg3的物理上行共享信道(physical uplink shared channel，PUSCH)资源、第四消息(Msg4)的混合自动重传请求(hybrid automatic repeat request，HARQ)-肯定确认(acknowledgment，ACK)反馈使用的公共PUCCH资源等。
由于初始上行BWP的最大带宽不能超过终端设备支持的最大带宽，第一类终端设备的初始上行BWP的频域范围和第二类终端设备的初始上行BWP的频域范围不同，因此网络设备在不确定终端设备的类型的情况下，调度接入过程中的一些上行信道时容易出现传输错误。例如，由于第一类终端设备的初始上行BWP和第二类终端设备的初始上行BWP的频域范围不同，因此网络设备需要识别出当前接入的用户是第一类终端设备还是第二类终端设备，以确定在哪个初始上行BWP范围内调度当前接入的终端设备的上行传输，例如Msg3传输，否则可能出现传输错误。
基于此，本申请实施例提供一种通信方法及装置，可以解决网络设备在不确定终端设备的类型的情况下，调度随机接入过程中的一些上行信道时出现传输错误的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请提供的通信方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)、窄带物联网(narrow band internet of things，NB-IoT)、长期演进(long term evolution，LTE)，也可以是第五代(5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(new radio，NR)系统以及6G或者未来通信发展中出现的新的通信系统等。本申请所述的5G通信系统可以包括非独立组网(non-standalone，NSA)的5G通信系统、独立组网(standalone，SA)的5G通信系统中的至少一种。通信系统还可以是机器到机器(machine to machine，M2M)网络或者其他网络。
参阅图1所示，为本申请实施例提供的一种通信系统，该通信系统包括网络设备和六 个终端设备，即UE1～UE6。在该通信系统中，UE1～UE6可以发送上行数据给网络设备，网络设备可以接收UE1～UE6发送的上行数据。此外，UE4～UE6也可以组成一个子通信系统。网络设备可以发送下行信息给UE1、UE2、UE3、UE5，UE5可以基于设备到设备(device-to-device，D2D)技术发送下行信息给UE4、UE6。图1仅是一种示意图，并不对通信系统的类型，以及通信系统内包括的设备的数量、类型等进行具体限定。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题同样适用。
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描述。本申请实施例可以用于网络设备调度随机接入过程中的上行信道的场景中，例如，网络设备调度Msg1、Msg3、Msg4的HARQ-ACK反馈使用的公共PUCCH等上行信道。为了便于介绍，在下文中，结合网络设备调度Msg3的场景，以该方法由网络设备和终端设备执行为例进行说明。
参见图2，为本申请提供的一种通信方法的流程示意图。该方法包括：
S201，网络设备向第一终端设备发送第一初始上行BWP的配置信息。
其中，第一终端设备属于第一类终端设备，第一初始上行BWP可以为第一终端设备对应的初始上行BWP。

需要说明的是，本申请不限定S201和S202的先后顺序。
S203，网络设备发送第一信息。
其中，第一信息指示的第一频域资源在第一初始上行BWP的频域范围内，第一频域资源用于第一终端设备发送Msg3；第一信息指示的第二频域资源在第二初始上行BWP的频域范围内，第二频域资源用于第二终端设备发送Msg3。在第一信息指示Msg3的传输资源时，第一信息可以承载于Msg2或者其他专有信令中，在第一信息指示其他信道的传输资源时，第一信息可以承载于UE专有信令或者广播消息中。
一种示例性说明中，第一信息可以为资源指示值(resource indication value,RIV)。具体地，所述资源指示值为频域资源的资源指示值。下面以第一信息为RIV为例对网络设备调度Msg3的过程进行说明。
一种举例说明中，第一信息可以承载于随机接入响应上行授权(RAR UL grant)或者以临时小区无线网络临时标识(temporary cell RNTI，TC-RNTI)加扰的下行控制信息 (downlink control information，DCI)中。一种具体的实施方式中，第一信息可以承载于RAR UL grant或者以TC-RNTI加扰的DCI中的频域资源分配域。
具体的，网络设备可以向第一终端设备和第二终端设备中的至少一个终端设备发送第一信息，例如，网络设备向第一终端设备发送第一信息，或者，网络设备向第二终端设备发送第一信息。或者，网络设备也可以向第一终端设备和第二终端设备均发送第一信息。
可选的，在网络设备向第一终端设备发送第一信息之后，第一终端设备可以基于第一信息确定第一频域资源。第一终端设备可以在第一频域资源上发送Msg3。
在网络设备向第二终端设备发送第一信息之后，第二终端设备可以基于第一信息确定第二频域资源。第二终端设备可以在第二频域资源上发送Msg3。
本申请实施例中网络设备调度Msg3时可以针对两类终端设备发送相同的调度信息(即第一信息)，该调度信息可以指示第一终端设备在第一终端设备的初始上行BWP(即第一初始上行BWP)范围内进行Msg3传输，并且该调度信息可以指示第二终端设备在第二终端设备的初始上行BWP(即第二初始上行BWP)范围内进行Msg3传输。通过上述方式，网络设备在不确定终端设备的类型的情况下，可以通过相同的指示值调度不同BWP范围的终端设备进行Msg3传输，从而可以避免由于Msg3的调度资源不在终端设备的初始上行BWP范围内导致的传输错误。
下面对S203可能的具体实现过程进行示例性描述。
一种可能的实施方式一中，网络设备在调度Msg3时可以为第一终端设备和第二终端设备分配相同的频域资源，即第一频域资源的频域范围可以和第二频域资源的频域范围相同，也就是，第一频域资源的绝对频域位置和第二频域资源的绝对频域位置相同，且第一频域资源的长度和第二频域资源的长度相同。例如，一种实现方式中，网络设备可以在第一频域资源集合中为第一终端设备和第二终端设备分配Msg3的频域资源，其中，第一频域资源集合中任一频域资源对于第一终端设备的RIV和对于第二终端设备的RIV相同。在该实施方式中，第一频域资源和第二频域资源相同，为了便于描述，在该实施方式中，将第一频域资源和第二频域资源统一称为Msg3频域资源。
应理解，“频域资源对于第一终端设备(或者第二终端设备)的RIV”可以理解为网络设备针对第一终端设备(或者第二终端设备)确定的RIV。下面对网络设备针对第一终端设备、第二终端设备确定RIV的过程进行示例性描述。
示例一，针对第一终端设备，网络设备可以基于Msg3频域资源的起始位置、长度以及第一初始上行BWP的大小确定RIV，需要说明的是，这里Msg3频域资源的起始位置为Msg3频域资源在第一初始上行BWP内的起始位置，也就是Msg3频域资源在第一初始上行BWP内的相对频域位置，例如，这里Msg3频域资源的起始位置可以为在第一初始上行BWP内的RB索引。
针对第二终端设备，网络设备可以基于Msg3频域资源的起始位置、长度以及第二初始上行BWP的大小确定RIV，需要说明的是，这里Msg3频域资源的起始位置为Msg3频域资源在第二初始上行BWP内的起始位置，也就是Msg3频域资源第二初始上行BWP的相对频域位置，例如，这里Msg3频域资源的起始位置可以为在第二初始上行BWP内的RB索引。
本申请实施例中，Msg3频域资源的长度可以理解为连续分配的RB的长度或者数量。
下面对第一终端设备的Msg3频域资源的RIV的确定方法以及第二终端设备的Msg3 频域资源的RIV的确定方法进行举例说明。

示例二，针对第一终端设备和第二终端设备，网络设备可以基于Msg3频域资源的起始位置、长度以及第一初始上行BWP的大小确定RIV。
其中，网络设备确定第一终端设备和第二终端设备时采用的确定方法，与上述实施例中第一终端设备、第二终端设备的Msg3频域资源的RIV的确定方法类似，区别在于，示例一中，网络设备根据上述确定方法确定第一终端设备和第二终端设备的RIV时，
Figure PCTCN2022087666-appb-000025
的含义不同，例如，在确定第一终端设备的RIV时

Figure PCTCN2022087666-appb-000027

Figure PCTCN2022087666-appb-000028
的含义相同，
Figure PCTCN2022087666-appb-000029
均为第一初始上行BWP的大小即RB数。具体过程可以参阅示例一的相关描述，重复之处不再赘述。
相应的，第一终端设备、第二终端设备在接收到第一信息后可以根据第一信息以及第一初始上行BWP的大小确定Msg3频域资源。其中，第一终端设备、第二终端设备确定Msg3频域资源时采用的方法，与上述实施例中第一终端设备、第二终端设备确定Msg3频域资源的方法类似，区别在于，示例一中，第一终端设备和第二终端设备确定Msg3频域资源时，
Figure PCTCN2022087666-appb-000030
的含义不同，例如，第一终端设备确定Msg3频域资源时采用的是第一初始上行BWP的大小，即
Figure PCTCN2022087666-appb-000031

Figure PCTCN2022087666-appb-000033
的含义相同，即第一终端设备和第二终端设备确定Msg3频域资源时均采用第一初始上行BWP的大小，即
Figure PCTCN2022087666-appb-000034
均为第一初始上行BWP的大小即RB数。具体过程可以参阅示例一的相关描述，重复之处不再赘述。
可以理解的，针对第一终端设备和第二终端设备，网络设备也可以基于Msg3频域资源的起始位置、长度以及第二初始上行BWP确定RIV。相应的，第一终端设备、第二终端设备在接收到第一信息后可以根据第一信息以及第二初始上行BWP的大小确定Msg3频域资源。
可选的，在上述两个示例中，网络设备在确定第一终端设备的RIV时Msg3频域资源的起始位置也可以为Msg3频域资源在第二初始上行BWP内的起始位置。相应的，第一终端设备可以根据第二初始上行BWP的起始位置和根据第一信息确定出来的Msg3频域资源的起始位置确定Msg3频域资源的绝对频域位置。
或者，网络设备在确定第二终端设备的RIV时Msg3频域资源的起始位置也可以为Msg3频域资源在第一初始上行BWP内的起始位置。相应的，第二终端设备可以根据第一初始上行BWP的起始位置和根据第一信息确定出来的Msg3频域资源的起始位置确定Msg3频域资源的绝对频域位置。
以第二终端设备为例，第二终端设备根据第一初始上行BWP的起始位置和根据第一信息确定出来的Msg3频域资源的起始位置确定Msg3频域资源的绝对频域位置可以通过如下方法实现：采用第一初始上行BWP的起始位置确定Msg3的频域资源位置。或者，采用第二初始上行BWP的起始位置和第一偏移值共同确定Msg3频域资源的起始位置，第一偏移值为第一初始上行BWP的起始位置与第二初始上行BWP的起始位置之间的频域偏移值。其中，第一初始上行BWP的起始位置与第二初始上行BWP的起始位置之间的频域偏移值可以是网络设备通过信令通知的，也可以是第二终端设备根据第一初始上行BWP的配置信息和第二初始上行BWP的配置信息确定的。
第一终端设备根据第二初始上行BWP的起始位置和根据第一信息确定出来的Msg3频域资源的起始位置确定Msg3频域资源的绝对频域位置的方式与上述过程类似，这里不在重复赘述。
可选的，在上述实施方式一中，第一初始上行BWP与第二初始上行BWP的起始位置可以相同。例如，第一初始上行BWP与第二初始上行BWP的起始位置相同可以为协议预定义的。又例如，第一初始上行BWP与第二初始上行BWP的起始位置相同也可以为网络设备根据算法实现确定的。通过上述实施方式，网络设备调度的Msg3频域资源位于第二初始上行BWP的频域范围内，可以保证该Msg3频域资源也在第一初始上行BWP的频域范围内。
示例性的，网络设备为第一终端设备和第二终端设备分配的Msg3的频域资源可以如图3所示。
另一种可能的实施方式二中，网络设备在调度Msg3时可以为第一终端设备和第二终端设备分配不同的频域资源，即第一频域资源的频域范围和第二频域资源的频域范围可以不同。
例如，一种实现方式中，网络设备可以在第二频域资源集合中为第一终端设备分配第一频域资源，以及为第二终端设备分配第二频域资源。第二频域资源集合中包括至少一个频域资源子集合，其中，任一频域资源子集合包括第一类频域资源和第二类频域资源，在同一个频域资源子集合中，任一第一类频域资源对于第一终端设备的RIV和任一第二类频域资源对于第二终端设备的RIV相同。
在该实现方式中，第一频域资源可以为第二频域资源集合中的第一频域资源子集合中的第一类频域资源，第二频域资源可以为第二频域资源集合中的第一频域资源子集合中的第二类频域资源。
举例说明，第二频域资源包括至少一个频域资源子集合，其中，任一频域资源子集合包括频域资源1和频域资源2，频域资源1对于第一终端设备的RIV和频域资源2对于第二终端设备的RIV相同。网络设备可以在该第二频域资源集合中为第一终端设备分配第一频域资源，以及为第二终端设备分配第二频域资源，例如，网络设备可以选择第二频域资源集合中的频域资源子集合1，将频域资源子集合1中的频域资源1分配给第一终端设备，将频域资源子集合1中的频域资源2分配给第二终端设备。
一个具体的例子中，以TDD 100MHz&30kHz，第一初始上行BWP大小273PRB,第二初始上行BWP大小51PRB为例，第二频域资源集合的频域资源集合1包括一个在第一初始上行BWP内调度的频域资源A，频域资源A的起始位置为0，长度为2，还包括一个第二初始上行BWP内调度的频域资源B，频域资源B的起始位置为18，长度为6。网络设备针对第一终端设备确定RIV时，可以根据上述实施方式一中的公式，其中，RB start为0，L RBs为2，
Figure PCTCN2022087666-appb-000035
为273计算出来的RIV为273。网络设备针对第二终端设备确定RIV时，可以根据上述实施方式一中的公式，其中，RB start为18，L RBs为6，
Figure PCTCN2022087666-appb-000036
为51计算出来的RIV为273。从而网络设备可以为第一终端设备分配的RB start为0，L RBs为2的第一频域资源，为第二终端设备分配RB start为18，L RBs为6的第二频域资源。
可选的，实施方式二中网络设备针对第一终端设备和第二终端设备确定RIV的过程与上述实施方式一中网络设备针对第一终端设备和第二终端设备确定RIV的过程类似，区别在于，上述实施方式一中，网络设备针对第一终端设备和第二终端设备确定RIV时 基于的是相同的频域资源(即上述Msg3频域资源)，而实施方式二中，网络设备针对第一终端设备和第二终端设备确定RIV时基于的是不同的频域资源具体的，网络设备针对第一终端设备确定RIV时基于的是第一频域资源，针对第二终端设备确定RIV时基于的是第二频域资源，具体过程可以参阅实施方式一的相关描述，重复之处不再赘述。
相应的，实施方式二中第一终端设备、第二终端设备确定Msg3的频域资源的方式与上述实施方式一类似，区别在于，上述实施方式一中第一终端设备和第二终端设备确定的是相同的频域资源(即上述Msg3频域资源)，而实施方式二中第一终端设备确定的是第一频域资源，第二终端设备确定的是第二频域资源，具体方法可以参阅上述实施方式一的相关描述，重复之处这里不再赘述。
示例性的，网络设备为第一终端设备和第二终端设备分配的Msg3的频域资源可以如图4所示。
在一些实施例中，在步骤S203之后，网络设备可以检测第一终端设备和/或第二终端设备发送的Msg3，例如，网络设备可以在第一频域资源上检测第一终端设备发送的Msg3，在第二频域资源上检测第二终端设备发送的Msg3。
如果检测到第一终端设备和/或第二终端设备发送的Msg3，则网络设备向第一终端设备和/或第二终端设备发送Msg4，否则通过下行控制信息(downlink control information，DCI)指示或者调度第一终端设备和/或第二终端设备重新传输Msg3，该DCI经过TC-RNTI加扰CRC。其中，该DCI携带的频域资源分配域中包含的RIV的确定方法可以参阅S203中第一信息的确定方法。
相应的，第一终端设备和/或第二终端设备检测TC-RNTI加扰CRC的DCI，如果该DCI指示的是Msg3的重传，则根据该DCI中信息重新发送Msg3。
可选的，如果该DCI指示的是Msg4，则根据该DCI中的信息接收Msg4。
本申请实施例中网络设备调度Msg3时可以针对两类终端设备发送相同的调度信息(即第一信息)，该调度信息可以指示第一终端设备在第一终端设备的初始上行BWP(即第一初始上行BWP)范围内进行Msg3传输，并且该调度信息可以指示第二终端设备在第二终端设备的初始上行BWP(即第二初始上行BWP)范围内进行Msg3传输。通过上述方式，网络设备在不确定终端设备的类型的情况下，可以通过相同的指示值调度不同BWP范围的终端设备进行Msg3传输，从而可以避免传输错误。
本申请实施例针对不同类型的终端设备可以分配相同的频域资源用于Msg3传输，使得网络设备可以不需要通过Msg1识别终端设备的类型，从而可以减少Msg1资源开销，且不存在Msg3资源浪费。并且，当网络设备针对不同类型的终端设备在不同的BWP范围内分配相同的频域资源时，可以通过约束初始上行BWP的起始位置相同或者考虑不同初始上行BWP间的起始位置的偏移值，来保证两类终端Msg3传输的绝对频域位置相同，避免出现传输错误。
本申请实施例针对不同类型的终端设备也可以分配不同的频域资源用于Msg3传输，使得网络设备可以不需要通过Msg1识别终端设备的类型，从而可以减少Msg1资源开销，且可以通过同一个信息使能工作到不同BWP范围的不同类型终端设备接入成功，从而在不增加信令开销的基础上可以增加终端设备的接入成功率。
