由于RedCap终端和非RedCap(Non-RedCap)终端存在一定区别，在接入网络时，为了使得网络确定接入终端的类型，RedCap终端在发起随机接入时，可以携带指示自身类型的信息，例如在发起两步随机接入时，可以通过随机接入消息MsgA中的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)进行早期指示early indication，用于指示发起随机接入的终端是否为RedCap终端。
如果基站没有正确获取MsgA中的PUSCH，可以通过向终端发送回退随机接入响应fallback RAR(Random Access Response)，其中携带有配置信息，以使终端根据配置信息向基站发送随机接入消息Msg3，Msg3为四步随机接入过程中的第三条消息，其中携带的内容与MsgA中的PUSCH相同或相近。但是在一些场景下，基站不能确定如何配置终端发送Msg3。

有鉴于此，本公开的实施例提出了资源配置方法、资源确定方法、资源配置装置、资源确定装置、通信装置和计算机可读存储介质，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种资源配置方法，适用于基站，所述基站配置第一类型终端的初始上行带宽部分Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为第二Initial UL BWP，所述方法包括：
接收终端发送的随机接入消息MsgA；
响应于未正确获取所述MsgA中的物理上行共享信道PUSCH，根据第一Initial UL BWP的配置信息确定资源分配信息；
向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
根据本公开实施例的第二方面，提出一种资源确定方法，适用于终端，所述方法包括：
向基站发送MsgA，接收所述基站发送的RAR，其中，所述基站配置第一类型终端的Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为第二Initial UL BWP；
响应于接收到的RAR为fallback RAR，从所述fallback RAR中获取资源分配信息，根据所述第一Initial UL BWP的配置信息解析所述资源分配信息以确定传输资源；
在所述传输资源向所述基站发送Msg3。
根据本公开实施例的第三方面，提出一种资源配置装置，适用于基站，所述基站配置第一类型终端的初始上行带宽部分Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为第二Initial UL BWP，所述装置包括一个或多个处理器，所述处理器被配置为执行：
接收终端发送的随机接入消息MsgA；
响应于未正确获取所述MsgA中的物理上行共享信道PUSCH，根据第一Initial UL BWP的配置信息确定资源分配信息；
向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
根据本公开实施例的第四方面，提出一种资源确定装置，所述装置包括一个或多个处理器，所述处理器被配置为执行：
向基站发送MsgA，接收所述基站发送的RAR，其中，所述基站配置第一类型终端的Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为 第二Initial UL BWP；
响应于接收到的RAR为fallback RAR，从所述fallback RAR中获取资源分配信息，根据所述第一Initial UL BWP的配置信息解析所述资源分配信息以确定传输资源；
在所述传输资源向所述基站发送Msg3。
根据本公开实施例的第五方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述资源配置方法。
根据本公开实施例的第六方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述资源确定方法。
根据本公开实施例的第七方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述资源配置方法中的步骤。
根据本公开实施例的第八方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述资源确定方法中的步骤。
根据本公开的实施例，基站在未正确获取MsgA中的PUSCH的情况下，可以默认需要终端在第一Initial UL BWP上发送Msg3，从而根据第一Initial UL BWP的配置信息确定资源分配信息，然后将资源分配信息携带在fallback RAR发送至终端。
进而终端在接收到RAR后，若确定RAR为fallback RAR后，在从fallback RAR中获取资源分配信息后，无论终端自身为何种类型的终端，都默认需要在第一Initial UL BWP上发送Msg3，从而根据第一Initial UL BWP的配置信息解析资源分配信息以确定传输资源，进而在确定的传输资源上向基站发送Msg3。
据此，虽然基站未正确获取MsgA中的PUSCH，尚未确定发送MsgA的终端的类型是否为RedCap终端，但是可以默认终端需要在第一Initial UL BWP上发送Msg3，并且终端在接收到fallback RAR后，也可以默认需要在第一Initial UL BWP上发送Msg3，从而基站可以根据第一Initial UL BWP的配置信息对传输资源进行处理得到资源分配信息，终端则可以根据第一Initial UL BWP的配置信息对资源分配信息进行解析以确定传输资源，并在确定的传输资源上完成Msg3的传输。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。 例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种资源配置方法的示意流程图。本实施例所示的资源配置方法可以适用于基站，所述基站可以终端(例如作为用户设备User Equipment，UE)通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图1所示，所述种资源配置方法可以包括以下步骤：
在步骤S101中，接收终端发送的随机接入消息MsgA；
在步骤S102中，响应于未正确获取所述MsgA中的物理上行共享信道PUSCH，根据第一Initial UL BWP的配置信息确定资源分配信息；
在步骤S103中，向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
在上述实施例中，基站配置第一类型终端的Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为第二Initial UL BWP。在一个实施例中，所述第一类型终端包括非能力降低RedCap终端，所述第二类型终端包括RedCap终端。
本公开实施例的方案可以为：基站接收终端发送的随机接入消息MsgA；响应于能够确定所述终端为第二类型终端(RedCap终端)，根据第二Initial UL BWP的配置信息确定资源分配信息；向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
本公开实施例的方案还可以为：基站接收终端发送的随机接入消息MsgA；响应于无法确定所述终端的类型，根据第一Initial UL BWP的配置信息确定资源分配信 息；向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
也可以说，如果能够确定发起随机接入的终端的类型为RedCap终端，则根据第二Initial UL BWP的配置信息确定资源分配信息。如果无法能够确定发起随机接入的终端的类型，则默认根据第一Initial UL BWP的配置信息确定资源分配信息。
在本公开实施例中，基站可以根据MsgA确定终端的类型，即：如果能够从MsgA中正确获取(例如正确解调出)物理上行共享信道PUSCH，则可以确定终端的类型。
在一个实施例中，终端可以向基站发起随机接入以接入基站，例如发起两步随机接入或者发起四步随机接入。
在四步随机接入过程中，终端首先向终端发送随机接入消息Msg1，其中携带有物理随机接入信道(Physical Random Access Channel，PRACH)前导码preamble；
基站在检测到前导码后，向终端发送随机接入响应RAR，也可以称作随机接入消息Msg2，RAR中可以携带有检测到的前导码的标识ID、定时提前量相关命令、临时C-RNTI(Cell-RadioNetworkTemporaryIdentifier，小区无线网络临时标识)也可以称作TC-RNTI，还可以携带有资源分配信息，资源分配信息用于指示终端发送随机接入消息Msg3的资源；
终端在接收到RAR后，可以向基站发送Msg3；在一种可能的实施方式中，Msg3主要是PUSCH，其中携带的具体内容不固定，取决于实际场景；
基站接收到Msg3后，使用竞争解决标识ID向终端发送竞争解决消息，可以称作随机接入消息Msg4；
终端接收到Msg4后，获取其中的竞争解决标识ID，然后在物理上行控制信道(Physical Uplink Control Channel，PUCCH)上向基站发送确认消息，完成四步随机接入过程。
可见，四步接入过程至少需要终端与基站之间往返通信两个周期，这在一定程度上会增加接入过程的时延，并且还产生了额外的信令开销，因此，在一些情况下，可以通过两步随机接入来缓解这些问题。
在两步随机接入过程中，终端向基站发送随机接入消息MsgA，MsgA由PRACH前导码和PUSCH组成，相当于四步随时接入过程中的Msg1和Msg3，可以在四步随机接入过程传输Msg1的PRACH场合(PO)传输，也可以独立的PO(例如在两步随机接入专用PO)中传输；
基站接收到MsgA后，向终端发送MsgB，其中包括随机接入响应和竞争解决消息；相当于四步随机接入过程中的Msg2和Msg4。
可见，基于两步随机接入过程可以减少接入过程中基站与终端的交互过程，有利于降低接入过程的时延，节约信令开销，例如终端与基站在非授权频段通信，由于两步随机接入过程所需交互次数较少，有利于对非授权频段先听后说(Listen Before Talk，LBT)尝试次数。
在两步随机接入过程中，终端在发送MsgA后，接收基站发送MsgB，可以存三种情况：
情况一，基站没有检测到MsgA中的PRACH前导码，从而没有向终端发送响应，也就没有向终端发送MsgB，终端等待后没有接收到MsgB，可以重新发送MsgA，或者回退到四步随机接入过程发送Msg1；
情况二，基站检测到了MsgA中的PRACH前导码，但是对于MsgA中的PUSCH未能正确解码，那么可以向终端发送fallback RAR，fallback RAR中至少携带有资源分配信息，例如上行链路授权UL grant，用于指示终端传输Msg3的资源，终端接收到fallback RAR后，则可以根据所指示的资源发送Msg3，相当于回退到四步随机接入过程；
情况三，基站检测到了MsgA中的PRACH前导码，对于MsgA中的PUSCH也正确解码了，可以向终端返回MsgB，其中可以携带成功随机接入响应successRAR，successRAR可以携带竞争解决标识ID、C-RNTI、定时提前量命令等，终端接收到MsgB可以确定成功完成两步随机接入过程。
对于RedCap终端，为了使得网络能够尽快确定终端的类型，在发起两步随机接入过程时，可以通过MsgA中的PUSCH进行early indication，指示方式可以是显示指示，也可以是隐式指示，用于指示终端发起随机接入的终端的类型，例如是否为RedCap终端。
另外，由于网络中可以存在传统(legacy)终端，也即非能力降低RedCap (Non-RedCap)终端，也可以存在能力降低RedCap终端，为了避免不同类型终端之间发起随机接入出现冲突，基站可以给RedCap终端和非RedCap终端配置不同的初始上行带宽部分Initial UL BWP(Bandwidth Part)，使得RedCap终端和非RedCap终端可以分别使用不同的Initial UL BWP发起随机接入。
以下为了方便描述，将基站给非RedCap终端配置的Initial UL BWP称作第一Initial UL BWP，给RedCap终端配置的Initial UL BWP称作第二Initial UL BWP，第一Initial UL BWP和第二Initial UL BWP不同。
在本公开的所有实施例中，第一Initial UL BWP和第二Initial UL BWP不同可以示例性的为以下的一种或多种情况：
第一Initial UL BWP和第二Initial UL BWP的宽带宽度不同；
第一Initial UL BWP和第二Initial UL BWP的起始位置和/或结束位置不同。
在一些可能的实施方式中，第一Initial UL BWP和第二Initial UL BWP可以由重叠的部分，或第一Initial UL BWP和第二Initial UL BWP完全不重叠，或第一Initial UL BWP完全包含在第二Initial UL BWP内，或第二Initial UL BWP完全包含在第一Initial UL BWP内。
在一种可能的实现方式中，给RedCap终端配置的Initial UL BWP称作第一Initial UL BWP，专供RedCap终端使用。给非RedCap终端配置的Initial UL BWP称作第二Initial UL BWP，既可以配置给RedCap终端使用，也可以配置给非RedCap终端使用。
在这种情况下，对于上述两步随机接入的情况二，基站没有正确获取MsgA中的PUSCH，也就不能正确获取到early indication，从而不能确定发起随机接入的终端的类型，进而导致基站不能确定配置终端在第一Initial UL BWP上发送Msg3，还是在第二Initial UL BWP上发送Msg3。当然，未能正确获取MsgA中的PUSCH只是触发下发fallback RAR的一种情况，本领域内技术人员可以理解，基站可以基于通信协议或其他条件，触发下发fallback RAR，本公开实施例并不对此做出限定。
根据本公开的实施例，基站可以默认需要终端在第一Initial UL BWP上发送Msg3，从而根据第一Initial UL BWP的配置信息确定资源分配信息，然后将资源分配信息携带在fallback RAR发送至终端。例如：基站在无法确定发送该MsgA的终端的类型的情况下，默认配置终端在第一Initial UL BWP上发送Msg3。在能够确定发送该 MsgA的终端为RedCap终端的情况下，可以配置终端在第一Initial UL BWP上发送Msg3，也可以配置终端在第二Initial UL BWP上发送Msg3；当然，由于第二Initial UL BWP是对应于RedCap终端的，可以优选配置终端在第二Initial UL BWP上发送Msg3。
例如基站可以先确定终端传输Msg3的传输资源，然后根据第一Initial UL BWP的配置信息对所确定的传输资源进行处理，以得到资源分配信息。
进而终端在接收到RAR后，若确定RAR为fallback RAR后，在从fallback RAR中获取资源分配信息后，无论终端自身为何种类型的终端，都默认需要在第一Initial UL BWP上发送Msg3，从而根据第一Initial UL BWP的配置信息解析资源分配信息以确定传输资源，进而在确定的传输资源上向基站发送Msg3。其中，传输的Msg3可以进行早期指示，也可以不进行早期指示，具体可以根据需要进行设置。
据此，虽然基站未成功确定发送MsgA的终端的类型是否为RedCap终端，但是可以默认终端需要在第一Initial UL BWP上发送Msg3，并且终端在接收到fallback RAR后，也可以默认需要在第一Initial UL BWP上发送Msg3，从而基站可以根据第一Initial UL BWP的配置信息对传输资源进行处理得到资源分配信息，终端则可以根据第一Initial UL BWP的配置信息对资源分配信息进行解析以确定传输资源，并在确定的传输资源上完成Msg3的传输。
另外，在一般情况下，网络中的传统终端，也即非RedCap终端占相对多数。如果默认终端在第二Initial UL BWP上发送Msg3，那么基站就会按照第二Initial UL BWP的配置信息对传输资源进行处理得到资源分配信息，相应地，如果发起随机接入的终端为非RedCap终端，也就需要非RedCap终端按照第二Initial UL BWP的配置信息对资源分配信息进行解析来确定传输资源了，但是目前非RedCap默认是按照第一Initial UL BWP的配置信息对资源分配信息进行解析的，若调整为按照第二Initial UL BWP的配置信息对资源分配信息进行解析来确定传输资源，将需要对大量的传统终端进行调整，实现难度过大。
因此，而RedCap终端作为新类型的终端，在网络中的数量相对较少，虽然目前RedCap默认是按照第二Initial UL BWP的配置信息对资源分配信息进行解析的，但是调整为按照第一Initial UL BWP的配置信息对资源分配信息进行解析，所需调整的终端的数量并不多，实现相对容易。
在一个实施例中，对于两步随机接入成功的情况，基站正确获取(例如正确解 调出)了MsgA中的PUSCH，也就能够确定终端的类型。
那么在确定终端类型为RedCap终端的情况下，可以根据第二Initial UL BWP的配置信息确定资源分配信息，并携带在successRAR中发送至终端，RedCap终端在确定接收到successRAR的情况下，可以按照第二Initial UL BWP的配置信息解析资源分配信息以确定传输资源；
而在确定终端类型为非RedCap终端的情况下，可以根据第一Initial UL BWP的配置信息确定资源分配信息，并携带在successRAR中发送至终端，非RedCap终端在确定接收到successRAR的情况下，可以按照第一Initial UL BWP的配置信息解析资源分配信息以确定传输资源。
在一个实施例中，所述第一Initial UL BWP的配置信息包括以下至少之一：
所述第一Initial UL BWP的带宽大小；
所述第一Initial UL BWP的子载波间隔SCS(SubCarrier Spacing)；
所述第一Initial UL BWP的物理资源块PRB(Physical Resource Block)的位置。
在一个实施例中，关于第一Initial UL BWP的配置信息和第二Initial UL BWP的配置信息，终端可以预先存储，例如可以由通信协议规定，也可以由基站广播，例如携带在系统信息中广播。
在一个实施例中，终端传输Msg3所需的传输资源，可以包括以下至少之一：
频域资源、时域资源、跳频传输(frequency hopping，例如时隙内intra-slot跳频)方案。以下主要针对这三种情况，分别描述根据第一Initial UL BWP的配置信息确定资源分配信息。
图2是根据本公开的实施例示出的另一种资源配置方法的示意流程图。如图2所示，所述根据第一Initial UL BWP的配置信息确定资源分配信息包括：
在步骤S201中，确定指示所述终端传输Msg3的频域资源；
在步骤S202中，根据所述第一Initial UL BWP的带宽大小、所述第一Initial UL BWP的SCS和所述第一Initial UL BWP的PRB的位置，对所述频域资源的信息进行处理以得到所述资源分配信息。
在一个实施例中，基站可以先确定需要终端传输Msg3的频域资源，然后根据所述第一Initial UL BWP的带宽大小、SCS和PRB的位置，对所述频域资源的信息进 行处理以得到所述资源分配信息。
例如确定的频域资源为10M带宽，第一Initial UL BWP的带宽、SCS、PRB的位置可以对这10M带宽起到限定作用，以限定这10M带宽在频域上的起始位置和结束位置，例如，可以确定频域资源为第一Initial UL BWP的带宽范围内的10M带宽。
进而终端接收到资源分配信息后，可以根据第一Initial UL BWP的带宽大小、SCS和PRB的位置，对所述资源分配信息进行解析，以确定用于传输Msg3的频域资源。例如资源分配信息指示了频域资源的起始位置对应的PRB序号和结束位置对应的PRB序号，那么终端可以根据第一Initial UL BWP的PRB的位置，确定频域资源的起始位置对应的PRB序号和结束位置对应的PRB序号第一Initial UL BWP的PRB的位置中分别对应的PRB的位置，进而根据确定的PRB的位置在频域上对应的资源为所述频域资源。需要说明的是，如图2所示的实施例可以与本公开的任一实施例一起被实施，也可以单独被实施，在此并不限定。
图3是根据本公开的实施例示出的又一种资源配置方法的示意流程图。如图3所示，所述根据第一Initial UL BWP的配置信息确定资源分配信息包括：
在步骤S301中，确定指示所述终端传输Msg3的时域资源；
在步骤S302中，根据所述第一Initial UL BWP的SCS，对所述时域资源的信息进行处理以得到所述资源分配信息。
在一个实施例中，基站可以先确定需要终端传输Msg3的时域资源，然后根据所述第一Initial UL BWP的SCS，对所述时域资源的信息进行处理以得到所述资源分配信息。
例如确定的时域资源为5个时域符号，第一Initial UL BWP的SCS可以对这5个时域符号起到限定作用，例如相对较大的SCS对应时域符号的长度较短，相对较大的SCS对应时域符号的长度较大。
进而终端接收到资源分配信息后，可以根据第一Initial UL BWP的SCS，对所述资源分配信息进行解析，以确定用于传输Msg3的时域资源。例如资源分配信息指示了时域资源对应的符号数量，那么终端可以根据第一Initial UL BWP的SCS，可以确定每个符号的大小，进而根据每个符号的大小符号数量确定时域资源的长度。需要说明的是，如图3所示的实施例可以与本公开的任一实施例一起被实施，也可以单独被实施，在此并不限定。
图4是根据本公开的实施例示出的又一种资源配置方法的示意流程图。如图4所示，所述根据第一Initial UL BWP的配置信息确定资源分配信息包括：
在步骤S401中，确定指示所述终端传输Msg3的跳频传输方案；
在步骤S402中，根据所述第一Initial UL BWP的带宽大小、所述第一Initial UL BWP的SCS和所述第一Initial UL BWP的PRB的位置，对所述跳频传输方案进行处理以得到所述资源分配信息。
在一个实施例中，基站在确定需要终端以跳频方式传输Msg3时，终端通过跳频方式传输Msg3，是指终端可以将Msg3划分为多个部分，例如划分为两个部分，其中一个部分从第一PRB开始传输，另一个部分从第二PRB开始传输，第一PRB和第二PRB不相邻，第一PRB和第二PRB之间的间隔可以称作offset。
基站可以先确定需要终端传输Msg3的跳频传输方案，然后根据第一Initial UL BWP的带宽大小、SCS和PRB的位置，对所述跳频传输方案进行处理以得到所述资源分配信息。
例如确定的跳频传输方案的offset为15M带宽，第一Initial UL BWP的带宽大小、SCS和PRB的位置可以对这15M带宽起到限定作用，例如根据第一Initial UL BWP的带宽大小可以将这15M带宽限制在第一Initial UL BWP范围内，根据第一Initial UL BWP的PRB的位置可以确定跳频传输方案在第一Initial UL BWP中起始位置对应的PRB和结束位置对应的PRB。
进而终端接收到资源分配信息后，可以根据所述第一Initial UL BWP的带宽大小、所述第一Initial UL BWP的SCS和所述第一Initial UL BWP的PRB的位置，对所述资源分配信息进行解析，以确定用于传输Msg3的跳频传输方案。例如资源分配信息指示了跳频传输的起始PRB的序号和结束PRB的序号，那么终端可以根据第一Initial UL BWP的PRB的位置，可以确定起始PRB的序号和结束PRB的序号分别对应的PRB的位置，进而确定跳频传输方案的offset。需要说明的是，如图3所示的实施例可以与本公开的任一实施例一起被实施，也可以单独被实施，在此并不限定。
图5是根据本公开的实施例示出的一种资源确定方法的示意流程图。本实施例所示的资源确定方法可以适用于终端，所述终端(例如作为用户设备User Equipment，UE)可以与基站通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述基站包括但不限于4G基站、5G基站、6G基站等通信 系统中的基站。
如图5所示，所述种资源确定方法可以包括以下步骤：
在步骤S501中，向基站发送MsgA，接收所述基站发送的RAR，其中，所述基站配置第一类型终端的Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为第二Initial UL BWP；
在步骤S502中，响应于接收到的RAR为fallback RAR，从所述fallback RAR中获取资源分配信息，根据所述第一Initial UL BWP的配置信息解析所述资源分配信息以确定传输资源；
在步骤S503中，在所述传输资源向所述基站发送Msg3。
在上述实施例中，基站配置第一类型终端的Initial UL BWP为第一Initial UL BWP，配置第二类型终端的Initial UL BWP为第二Initial UL BWP。在一个实施例中，所述第一类型终端包括非能力降低RedCap终端，所述第二类型终端包括RedCap终端。
本公开实施例的方案可以为：基站接收终端发送的随机接入消息MsgA；响应于能够确定所述终端为第二类型终端(RedCap终端)，根据第二Initial UL BWP的配置信息确定资源分配信息；向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
本公开实施例的方案还可以为：基站接收终端发送的随机接入消息MsgA；响应于无法确定所述终端的类型，根据第一Initial UL BWP的配置信息确定资源分配信息；向所述终端发送回退随机接入响应fallback RAR，其中，所述fallback RAR中携带有所述资源分配信息，用于指示所述终端根据所述资源分配信息向所述基站发送随机接入消息Msg3。
也可以说，如果能够确定发起随机接入的终端的类型为RedCap终端，则根据第二Initial UL BWP的配置信息确定资源分配信息。如果无法能够确定发起随机接入的终端的类型，则默认根据第一Initial UL BWP的配置信息确定资源分配信息。
在本公开实施例中，基站可以根据MsgA确定终端的类型，即：如果能够从MsgA中正确获取(例如正确解调出)物理上行共享信道PUSCH，则可以确定终端的类型。
在一个实施例中，终端可以向基站发起随机接入以接入基站，例如发起两步随机接入或者发起四步随机接入。
在四步随机接入过程中，终端首先向终端发送随机接入消息Msg1，其中携带有物理随机接入信道(Physical Random Access Channel，PRACH)前导码preamble；
基站在检测到前导码后，向终端发送随机接入响应RAR，也可以称作随机接入消息Msg2，RAR中可以携带有检测到的前导码的标识ID、定时提前量相关命令、临时C-RNTI(Cell-RadioNetworkTemporaryIdentifier，小区无线网络临时标识)也可以称作TC-RNTI，还可以携带有资源分配信息，资源分配信息用于指示终端发送随机接入消息Msg3的资源；
终端在接收到RAR后，可以向基站发送Msg3；在一种可能的实施方式中，Msg3主要是PUSCH，其中携带的具体内容不固定，取决于实际场景；
基站接收到Msg3后，使用竞争解决标识ID向终端发送竞争解决消息，可以称作随机接入消息Msg4；
终端接收到Msg4后，获取其中的竞争解决标识ID，然后在物理上行控制信道(Physical Uplink Control Channel，PUCCH)上向基站发送确认消息，完成四步随机接入过程。
可见，四步接入过程至少需要终端与基站之间往返通信两个周期，这在一定程度上会增加接入过程的时延，并且还产生了额外的信令开销，因此，在一些情况下，可以通过两步随机接入来缓解这些问题。
在两步随机接入过程中，终端向基站发送随机接入消息MsgA，MsgA由PRACH前导码和PUSCH组成，相当于四步随时接入过程中的Msg1和Msg3，可以在四步随机接入过程传输Msg1的PRACH场合(PO)传输，也可以独立的PO(例如在两步随机接入专用PO)中传输；
基站接收到MsgA后，向终端发送MsgB，其中包括随机接入响应和竞争解决消息；相当于四步随机接入过程中的Msg2和Msg4。
可见，基于两步随机接入过程可以减少接入过程中基站与终端的交互过程，有利于降低接入过程的时延，节约信令开销，例如终端与基站在非授权频段通信，由于两步随机接入过程所需交互次数较少，有利于对非授权频段先听后说(Listen Before Talk，LBT)尝试次数。
在两步随机接入过程中，终端在发送MsgA后，接收基站发送MsgB，可以存三种情况：
情况一，基站没有检测到MsgA中的PRACH前导码，从而没有向终端发送响应，也就没有向终端发送MsgB，终端等待后没有接收到MsgB，可以重新发送MsgA，或者回退到四步随机接入过程发送Msg1；
情况二，基站检测到了MsgA中的PRACH前导码，但是对于MsgA中的PUSCH未能正确解码，那么可以向终端发送fallback RAR，fallback RAR中至少携带有资源分配信息，例如上行链路授权UL grant，用于指示终端传输Msg3的资源，终端接收到fallback RAR后，则可以根据所指示的资源发送Msg3，相当于回退到四步随机接入过程；
情况三，基站检测到了MsgA中的PRACH前导码，对于MsgA中的PUSCH也正确解码了，可以向终端返回MsgB，其中可以携带成功随机接入响应successRAR，successRAR可以携带竞争解决标识ID、C-RNTI、定时提前量命令等，终端接收到MsgB可以确定成功完成两步随机接入过程。
对于RedCap终端，为了使得网络能够尽快确定终端的类型，在发起两步随机接入过程时，可以通过MsgA中的PUSCH进行early indication，指示方式可以是显示指示，也可以是隐式指示，用于指示终端发起随机接入的终端的类型，例如是否为RedCap终端。
另外，由于网络中可以存在传统(legacy)终端，也即非能力降低RedCap(Non-RedCap)终端，也可以存在能力降低RedCap终端，为了避免不同类型终端之间发起随机接入出现冲突，基站可以给RedCap终端和非RedCap终端配置不同的初始上行带宽部分Initial UL BWP(Bandwidth Part)，使得RedCap终端和非RedCap终端可以分别使用不同的Initial UL BWP发起随机接入。
以下为了方便描述，将基站给非RedCap终端配置的Initial UL BWP称作第一Initial UL BWP，给RedCap终端配置的Initial UL BWP称作第二Initial UL BWP，第一Initial UL BWP和第二Initial UL BWP不同。
在本公开的所有实施例中，第一Initial UL BWP和第二Initial UL BWP不同可以示例性的为以下的一种或多种情况：
第一Initial UL BWP和第二Initial UL BWP的宽带宽度不同；
第一Initial UL BWP和第二Initial UL BWP的起始位置和/或结束位置不同。
在一些可能的实施方式中，第一Initial UL BWP和第二Initial UL BWP可以由重叠的部分，或第一Initial UL BWP和第二Initial UL BWP完全不重叠，或第一Initial UL BWP完全包含在第二Initial UL BWP内，或第二Initial UL BWP完全包含在第一Initial UL BWP内。
在一种可能的实现方式中，给RedCap终端配置的Initial UL BWP称作第一Initial UL BWP，专供RedCap终端使用。给非RedCap终端配置的Initial UL BWP称作第二Initial UL BWP，既可以配置给RedCap终端使用，也可以配置给非RedCap终端使用。
在这种情况下，对于上述两步随机接入的情况二，基站没有正确获取MsgA中的PUSCH，也就不能正确获取到early indication，从而不能确定发起随机接入的终端的类型，进而导致基站不能确定配置终端在第一Initial UL BWP上发送Msg3，还是在第二Initial UL BWP上发送Msg3。当然，未能正确获取MsgA中的PUSCH只是触发下发fallback RAR的一种情况，本领域内技术人员可以理解，基站可以基于通信协议或其他条件，触发下发fallback RAR，本公开实施例并不对此做出限定。
根据本公开的实施例，基站可以默认需要终端在第一Initial UL BWP上发送Msg3，从而根据第一Initial UL BWP的配置信息确定资源分配信息，然后将资源分配信息携带在fallback RAR发送至终端。例如：基站在无法确定发送该MsgA的终端的类型的情况下，默认配置终端在第一Initial UL BWP上发送Msg3。在能够确定发送该MsgA的终端为RedCap终端的情况下，可以配置终端在第一Initial UL BWP上发送Msg3，也可以配置终端在第二Initial UL BWP上发送Msg3；当然，由于第二Initial UL BWP是对应于RedCap终端的，可以优选配置终端在第二Initial UL BWP上发送Msg3。
例如基站可以先确定终端传输Msg3的传输资源，然后根据第一Initial UL BWP的配置信息对所确定的传输资源进行处理，以得到资源分配信息。
进而终端在接收到RAR后，若确定RAR为fallback RAR后，在从fallback RAR中获取资源分配信息后，无论终端自身为何种类型的终端，都默认需要在第一Initial UL BWP上发送Msg3，从而根据第一Initial UL BWP的配置信息解析资源分配信息以确定传输资源，进而在确定的传输资源上向基站发送Msg3。其中，传输的Msg3可以进行早期指示，也可以不进行早期指示，具体可以根据需要进行设置。
据此，虽然基站未成功确定发送MsgA的终端的类型是否为RedCap终端，但是可以默认终端需要在第一Initial UL BWP上发送Msg3，并且终端在接收到fallback RAR后，也可以默认需要在第一Initial UL BWP上发送Msg3，从而基站可以根据第一Initial UL BWP的配置信息对传输资源进行处理得到资源分配信息，终端则可以根据第一Initial UL BWP的配置信息对资源分配信息进行解析以确定传输资源，并在确定的传输资源上完成Msg3的传输。
另外，在一般情况下，网络中的传统终端，也即非RedCap终端占相对多数。如果默认终端在第二Initial UL BWP上发送Msg3，那么基站就会按照第二Initial UL BWP的配置信息对传输资源进行处理得到资源分配信息，相应地，如果发起随机接入的终端为非RedCap终端，也就需要非RedCap终端按照第二Initial UL BWP的配置信息对资源分配信息进行解析来确定传输资源了，但是目前非RedCap默认是按照第一Initial UL BWP的配置信息对资源分配信息进行解析的，若调整为按照第二Initial UL BWP的配置信息对资源分配信息进行解析来确定传输资源，将需要对大量的传统终端进行调整，实现难度过大。
因此，而RedCap终端作为新类型的终端，在网络中的数量相对较少，虽然目前RedCap默认是按照第二Initial UL BWP的配置信息对资源分配信息进行解析的，但是调整为按照第一Initial UL BWP的配置信息对资源分配信息进行解析，所需调整的终端的数量并不多，实现相对容易。
在一个实施例中，对于两步随机接入成功的情况，基站正确获取(例如正确解调出)了MsgA中的PUSCH，也就能够确定终端的类型。
那么在确定终端类型为RedCap终端的情况下，可以根据第二Initial UL BWP的配置信息确定资源分配信息，并携带在successRAR中发送至终端，RedCap终端在确定接收到successRAR的情况下，可以按照第二Initial UL BWP的配置信息解析资源分配信息以确定传输资源；
而在确定终端类型为非RedCap终端的情况下，可以根据第一Initial UL BWP的配置信息确定资源分配信息，并携带在successRAR中发送至终端，非RedCap终端在确定接收到successRAR的情况下，可以按照第一Initial UL BWP的配置信息解析资源分配信息以确定传输资源。
在一个实施例中，所述第一Initial UL BWP的配置信息包括以下至少之一：
所述第一Initial UL BWP的带宽大小；
所述第一Initial UL BWP的SCS；
所述第一Initial UL BWP的PRB的位置。
在一个实施例中，关于第一Initial UL BWP的配置信息和第二Initial UL BWP的配置信息，终端可以预先存储，例如可以由通信协议规定，也可以由基站广播，例如携带在系统信息中广播。
在一个实施例中，终端传输Msg3所需的传输资源，可以包括以下至少之一：
频域资源、时域资源、跳频传输(frequency hopping，例如时隙内intra-slot跳频)方案。以下主要针对这三种情况，分别描述根据第一Initial UL BWP的配置信息确定资源分配信息。
图6是根据本公开的实施例示出的另一种资源确定方法的示意流程图。如图6所示，所述根据所述第一Initial UL BWP的配置信息解析所述资源分配信息以确定传输资源包括：
在步骤S601中，根据所述第一Initial UL BWP的带宽大小、所述第一Initial UL BWP的SCS和所述第一Initial UL BWP的PRB的位置，对所述资源分配信息进行解析，以确定用于传输Msg3的频域资源。
在一个实施例中，基站可以先确定需要终端传输Msg3的频域资源，然后根据所述第一Initial UL BWP的带宽大小、SCS和PRB的位置，对所述频域资源的信息进行处理以得到所述资源分配信息。
例如确定的频域资源为10M带宽，第一Initial UL BWP的带宽、SCS、PRB的位置可以对这10M带宽起到限定作用，以限定这10M带宽在频域上的起始位置和结束位置，例如，可以确定频域资源为第一Initial UL BWP的带宽范围内的10M带宽。
进而终端接收到资源分配信息后，可以根据第一Initial UL BWP的带宽大小、SCS和PRB的位置，对所述资源分配信息进行解析，以确定用于传输Msg3的频域资源。例如资源分配信息指示了频域资源的起始位置对应的PRB序号和结束位置对应的PRB序号，那么终端可以根据第一Initial UL BWP的PRB的位置，确定频域资源的起始位置对应的PRB序号和结束位置对应的PRB序号第一Initial UL BWP的PRB的位置中分别对应的PRB的位置，进而根据确定的PRB的位置在频域上对应的资源为所 述频域资源。需要说明的是，如图6所示的实施例可以与本公开的任一实施例一起被实施，也可以单独被实施，在此并不限定。
图7是根据本公开的实施例示出的又一种资源确定方法的示意流程图。如图7所示，所述根据所述第一Initial UL BWP的配置信息解析所述资源分配信息以确定传输资源包括：
在步骤S701中，根据所述第一Initial UL BWP的SCS，对所述资源分配信息进行解析，以确定用于传输Msg3的时域资源。
在一个实施例中，基站可以先确定需要终端传输Msg3的时域资源，然后根据所述第一Initial UL BWP的SCS，对所述时域资源的信息进行处理以得到所述资源分配信息。
例如确定的时域资源为5个时域符号，第一Initial UL BWP的SCS可以对这5个时域符号起到限定作用，例如相对较大的SCS对应时域符号的长度较短，相对较大的SCS对应时域符号的长度较大。
进而终端接收到资源分配信息后，可以根据第一Initial UL BWP的SCS，对所述资源分配信息进行解析，以确定用于传输Msg3的时域资源。例如资源分配信息指示了时域资源对应的符号数量，那么终端可以根据第一Initial UL BWP的SCS，可以确定每个符号的大小，进而根据每个符号的大小符号数量确定时域资源的长度。需要说明的是，如图7所示的实施例可以与本公开的任一实施例一起被实施，也可以单独被实施，在此并不限定。
图8是根据本公开的实施例示出的又一种资源确定方法的示意流程图。如图8所示，所述根据所述第一Initial UL BWP的配置信息解析所述资源分配信息以确定传输资源包括：
在步骤S801中，根据所述第一Initial UL BWP的带宽大小、所述第一Initial UL BWP的SCS和所述第一Initial UL BWP的PRB的位置，对所述资源分配信息进行解析，以确定用于传输Msg3的跳频传输方案。
在一个实施例中，基站在确定需要终端以跳频方式传输Msg3时，终端通过跳频方式传输Msg3，是指终端可以将Msg3划分为多个部分，例如划分为两个部分，其中一个部分从第一PRB开始传输，另一个部分从第二PRB开始传输，第一PRB和第二PRB不相邻，第一PRB和第二PRB之间的间隔可以称作offset。需要说明的是， 如图8所示的实施例可以与本公开的任一实施例一起被实施，也可以单独被实施，在此并不限定。
基站可以先确定需要终端传输Msg3的跳频传输方案，然后根据第一Initial UL BWP的带宽大小、SCS和PRB的位置，对所述跳频传输方案进行处理以得到所述资源分配信息。
例如确定的跳频传输方案的offset为15M带宽，第一Initial UL BWP的带宽大小、SCS和PRB的位置可以对这15M带宽起到限定作用，例如根据第一Initial UL BWP的带宽大小可以将这15M带宽限制在第一Initial UL BWP范围内，根据第一Initial UL BWP的PRB的位置可以确定跳频传输方案在第一Initial UL BWP中起始位置对应的PRB和结束位置对应的PRB。
进而终端接收到资源分配信息后，可以根据所述第一Initial UL BWP的带宽大小、所述第一Initial UL BWP的SCS和所述第一Initial UL BWP的PRB的位置，对所述资源分配信息进行解析，以确定用于传输Msg3的跳频传输方案。例如资源分配信息指示了跳频传输的起始PRB的序号和结束PRB的序号，那么终端可以根据第一Initial UL BWP的PRB的位置，可以确定起始PRB的序号和结束PRB的序号分别对应的PRB的位置，进而确定跳频传输方案的offset。
