图2示出了根据本公开实施例的一种初始BWP配置方法的流程示意图。如图2所示，该方法可由网络设备执行，且包括以下步骤。
S201，将BWP相关信息发送给终端，其中，BWP相关信息包括指示专用于能力降低特定类型终端的下行初始BWP的第一下行初始BWP信息和/或指示专用于特定类型终端的上行初始BWP的第一上行初始BWP信息。
在一些实施例中，特定类型终端指的是Redcap类型终端。
在一些实施例中，BWP相关信息携带在系统信息块类型1(System Information Block Type 1，SIB1)中。
作为一种实施方式，在SIB1中为特定类型终端添加信息元素(Information Element，IE)项，诸如“DownlinkConfigCommonSIB-Redcap”。
作为一个示例，用于特定类型终端的广播控制信道(Broadcast Control Channel，BCCH)配置可以与用于常规类型终端的BCCH配置相同，因此，无需在该IE项中包括BCCH配置字段。作为另一示例，可以在该IE项中包括BCCH配置字段，以为特定类型终端单独配置BCCH。
作为一个示例，用于特定类型终端的物理控制信道(Physical Control Channel，PCCH)配置可以与用于常规类型终端的PCCH配置相同，因此，无需在该IE项中包括PCCH配置字段。作为另一示例，可以在该IE项中包括PCCH配置字段，以为特定类型终端单独配置PCCH。
在一些实施例中，当BWP相关信息中包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息时，第一下行初始BWP信息可以具有以下搜索空间中至少一个：随机访问响应(Random Acess Response，RAR)搜索空间、寻呼搜索空间以及其他系统消息搜索空间。作为一个示例，该第一下行初始BWP信息包括控制资源集合0(CORESET0)，由此可以配置RAR搜索空间、寻呼搜索空间以及其他系统消息搜索空间中的至少一个。
在一些实施例中，当BWP相关信息中包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息时，第一下行初始BWP信息可以具有RAR搜索空间或寻呼搜索空间。作为一个示例，该第一下行初始BWP信息不包括控制资源集合0(CORESET0)，而仅配置RAR搜索空间。作为另一示例，该第一下行初始BWP信息不包括控制资源集合0(CORESET0)，而仅配置寻呼搜索空间。
在一些实施例中，当BWP相关信息中包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息时，第一下行初始BWP信息可以配置多个下行初始BWP，其上可以具有RAR搜索空间或寻呼搜索空间。比如配置两个下行初始BWP，其中包含寻呼搜索空间，用于特定类型终端寻呼消息的监听。

在一些实施例中，上述步骤S301包括：从SIB1中获取BWP相关信息。
作为一种实施方式，SIB1中包括用于特定类型终端的信息元素(Information Element，IE)项“DownlinkConfigCommonSIB-Redcap”。
作为一个示例，在该IE项中包括BCCH配置字段，该BCCH配置字段用于为特定类型终端单独配置BCCH。作为另一示例，在该IE项中不包括BCCH配置字段，这表示用于特定类型终端的BCCH配置可以与用于常规类型终端的BCCH配置相同，因此，可以复用用于常规类型终端的BCCH配置。
作为一个示例，在该IE项中包括PCCH配置字段，该PCCH配置字段用于为特定类型终端单独配置PCCH。作为另一示例，在该IE项中不包括PCCH配置字段，这表示用于特定类型终端的PCCH配置可以与用于常规类型终端的PCCH配置相同，因此，可以复用用于常规类型终端的PCCH配置。
在一些实施例中，当BWP相关信息中包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息时，第一下行初始BWP信息可以具有以下搜索空间中至少一个：RAR搜索空间、寻呼搜索空间以及其他系统消息搜索空间。作为一个示例，该第一下行初始BWP信息包括控制资源集合0(CORESET0)，由此可以配置RAR搜索空间、寻呼搜索空间以及其他系统消息搜索空间中的至少一个。
在一些实施例中，当BWP相关信息中包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息时，第一下行初始BWP信息可以具有RAR搜索空间或寻呼搜索空间。作为一个示例，该第一下行初始BWP信息不包括控制资源集合0(CORESET0)，而仅配置RAR搜索空间。作为另一示例，该第一下行初始BWP信息不包括控制资源集合0(CORESET0)，而仅配置寻呼搜索空间。

若BWP相关信息包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，则特定类型终端在获取到该BWP相关信息后，可以直接将该第一下行初始BWP信息所指示的下行初始BWP用作特定类型终端使用的下行初始BWP。
S4022，当BWP相关信息不包括第一下行初始BWP信息时，将第二下行初始BWP信息所指示的下行初始BWP确定为特定类型终端使用的下行初始BWP，其中第二下行初始BWP信息包括在BWP相关信息或主信息块中，以及第二下行初始BWP信息指示用于常规类型终端的下行初始BWP。
若BWP相关信息不包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，则可以将BWP相关信息或主信息块(Master Information Block，MIB)中所指示的用于常规类型终端的下行初始BWP用作特定类型终端使用的下行初始BWP。
作为一个示例，若BWP相关信息中所指示的用于常规类型终端的下行初始BWP满足特定类型终端的带宽需求，则可以将该用于常规类型终端的下行初始BWP作为特定类型终端使用的下行初始BWP。
作为一个示例，若BWP相关信息中所指示的用于常规类型终端的下行初始BWP不满足特定类型终端的带宽需求，则可以将MIB中所指示的用于常规类型终端的下行初始BWP用作特定类型终端使用的下行初始BWP。
S4023，当BWP相关信息包括第一上行初始BWP信息时，将第一上行初始BWP信息所指示的上行初始BWP确定为特定类型终端使用的上行初始BWP。
若BWP相关信息包括指示专用于特定类型终端的上行初始BWP的第一上行初始BWP信息，则特定类型终端在获取到该BWP相关信息后，可以直接将该第一上行初始BWP信息所指示的下行初始BWP用作特定类型终端使用的下行初始BWP。

若BWP相关信息不包括指示专用于特定类型终端的下行初始BWP的第一上行初始BWP信息，则可以将BWP相关信息中所指示的用于常规类型终端的上行初始BWP用作特定类型终端使用的上行初始BWP。
作为一个示例，若BWP相关信息中所指示的用于常规类型终端的上行初始BWP满足特定类型终端的带宽需求，则可以将该用于常规类型终端的上行初始BWP作为特定类型终端使用的上行初始BWP。
作为一个示例，对于时分复用(Time Division Duplexing，TDD)系统，若BWP相关信息中所指示的用于常规类型终端的上行初始BWP的中心频点与BWP相关信息中所指示的用于特定类型终端的下行初始BWP的中心频点对齐且满足特定类型终端的带宽需求，则可以将该用于常规类型终端的上行初始BWP作为特定类型终端使用的上行初始BWP。
根据本公开实施例的初始BWP配置方法，网络设备将指示特定类型终端的下行初始BWP和/或上行初始BWP的BWP相关信息发送给终端，以便特定类型终端能够根据该BWP相关信息确定下行初始BWP和上行初始BWP，从而实现对特定类型终端的初始BWP配置。

根据本公开实施例的初始BWP切换方法，根据从网络设备的MIB或SIB1中获取的BWP相关信息执行BWP切换，从而使得特定类型终端能够实现BWP切换。
图6示出了根据本公开实施例的一种初始BWP切换方法的流程示意图。本实施例基于图5所示的实施例，该方法可由处于连接态的特定类型终端执行，如图6所示，该初始BWP切换方法可以包括以下任一步骤。
S601，若当前激活BWP上无随机接入信道(Random Access Channel，RACH)，根据从网络设备发送的系统信息中获取的BWP相关信息执行上行BWP切换和下行BWP切换，其中，系统消息包括主信息块(Master Information Block，MIB)和/或系统信息块类型1(System Information Block Type 1，SIB1)。
若当前激活BWP上无RACH，则特定类型终端需要进行上行BWP切换和下行BWP切换。在本实施例中，特定类型终端可以根据从MIB和/或SIB1中获取的BWP相关信息来执行上行BWP切换和下行BWP切换。
S602，若当前激活BWP上的BWP非激活定时器超时且特定类型终端未被配置默认下行BWP，根据从网络设备发送的系统信息中获取的BWP相关信息执行下行BWP切换，其中，系统消息包括MIB和/或SIB1。
若当前激活BWP上的BWP非激活定时器超时且特定类型终端未被配置默认下行BWP，则特定类型终端需要进行下行BWP切换。在本实施例中，特定类型终端可以根据从MIB和/或SIB1中获取的BWP相关信息来执行下行BWP切换。
根据本公开实施例的初始BWP切换方法，若当前激活BWP上无RACH，根据从网络设备获取的BWP相关信息执行上行BWP切换和下行BWP切换；若当前激活BWP上的BWP非激活定时器超时且所述特定类型终端未被配置默认下行BWP，根据从网络设备获取的BWP相关信息执行下行BWP切换，从而能够特定类型终端能够实现BWP切换。
图7示出了根据本公开实施例的一种初始BWP切换方法的流程示意图。本实施例基于图6所示的实施例，该方法可由处于连接态的特定类型终端执行，如图7所示，该初始BWP切换方法可以包括以下步骤。
S701，若当前激活BWP上无随机接入信道(Random Access Channel，RACH)，根据从网络设备发送的系统信息中获取的BWP相关信息执行上行BWP切换和下行BWP切换，其中，系统消息包括主信息块(Master Information Block，MIB)和/或系统信息块类型1(System Information Block Type 1，SIB1)。
在一些实施例中，上述步骤S701包括以下任一步骤。
在进行上行BWP切换时，将上行BWP切换到具有为特定类型终端配置的随机接入资源的上行初始BWP。以下步骤S7011-S7013阐述了上行BWP切换的细节，即上行BWP切换可以通过以下步骤S7011-S7013中任一步骤实现。
S7011，当从SIB1中获取的BWP相关信息包括指示专用于特定类型终端的上行初始BWP的第一上行初始BWP信息时，将上行BWP切换至第一上行初始BWP信息所指示的上行初始BWP。
在本实施例中，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的上行初始BWP，特定类型终端都可以直接将上行BWP切换至该BWP相关信息指示的专用于特定类型终端的上行初始BWP。在本实施例中，假设从SIB1中获取的BWP相关信息指示专用于特定类型终端的上行初始BWP上具有为特定类型终端配置的随机接入资源。
S7012，当从SIB1中获取的BWP相关信息包括指示专用于特定类型终端的上行初始BWP的第一上行初始BWP信息，且第一上行初始BWP信息所指示的上行初始BWP具有为特定类型终端配置的随机接入资源时，将上行BWP切换至第一上行初始BWP信息所指示的上行初始BWP。
特定类型终端在执行上行BWP切换时，可以将上行BWP切换至具体为特定类型终端配置的随机接入资源的上行BWP。由此，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的上行初始BWP，可以确定该BWP相关信息指示的专用于特定类型终端的上行初始BWP是否具有为特定类型终端配置的随机接入资源，若有，则特定类型终端将上行BWP切换至该BWP相关信息指示的专用于特定类型终端的上行初始BWP。
在一个实施例中，假设网络配置了多个为特定类型终端配置的随机接入资源的上行BWP，则终端可以按照规则选择一个。比如随机选择一个。假设仅仅配置一个，则使用这一个即可。
S7013，当从SIB1中获取的BWP相关信息包括指示用于常规类型终端的上行初始BWP的第二上行初始BWP信息但不包括指示专用于特定类型终端的上行初始BWP的第一上行初始BWP信息时或当从SIB1中获取的BWP相关信息包括第一上行初始BWP信息和第二上行初始BWP信息但第一上行初始BWP信息所指示的上行初始BWP不具有为所述特定类型终端配置的随机接入资源时，将上行BWP切换至第一上行初始BWP信息所指示的上行初始BWP。
在本实施例中，若从SIB1中获取的BWP相关信息不指示专用于特定类型终端的上行初始BWP而仅指示用于常规类型终端的上行初始BWP，则特定类型终端可以将上行BWP切换至该BWP相关信息指示的用于常规类型终端的上行初始BWP。
或者，特定类型终端在执行上行BWP切换时，可以将上行BWP切换至具体为特定类型终端配置的随机接入资源的上行BWP。由此，若从SIB1中获取的BWP相关信息既指示用于常规类型终端的上行初始BWP又指示专用于特定类型终端的上行初始BWP，可以确定该BWP相关信息指示的专用于特定类型终端的上行初始BWP是否具有为特定类型终端配置的随机接入资源，若没有，则特定类型终端将上行BWP切换至该BWP相关信息指示的专用于特定类型终端的上行初始BWP。
优选地，在执行上行BWP切换时，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的上行初始BWP，则特定类型终端将上行BWP切换至该专用于特定类型终端的上行初始BWP，否则特定类型终端将上行BWP切换至用于常规类型终端的上行初始BWP，其伪代码示例如下：
For特定类型终端：
If SIB1指示用于特定类型终端的上行的初始BWP，
则将上行BWP切换到所指示的用于特定类型终端的上行初始BWP；
Else
则将上行BWP切换到切换到SIB1所指示的用于常规类型终端的上行初始BWP.
在进行下行BWP切换时，将下行BWP切换到具有为特定类型终端的RAR搜索空间的下行初始BWP。以下步骤S7014-S7018阐述了下行BWP切换的细节，即下行BWP切换可以通过以下步骤S7014-S7018中任一步骤实现。

具体地，上述步骤S7014可以通过以下任一步骤来实现。
S70141，当从SIB1中获取的BWP相关信息包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，且第一下行初始BWP信息所指示的下行初始BWP具有RAR搜索空间时，将下行BWP切换至第一下行初始BWP信息所指示的下行初始BWP。
在本实施例中，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的具有RAR搜索空间的下行初始BWP，无论从SIB1中获取的BWP相关信息是否指示用于常规类型终端的下行初始BWP，特定类型终端都可以直接将下行BWP切换至该BWP相关信息指示的用于特定类型终端的具有RAR搜索空间的下行初始BWP。
在一个实施例中，假设网络配置了多个为特定类型终端配置的具有RAR搜索空间的下行初始BWP，则终端可以按照规则选择一个。比如选和为特定类型终端配置的随机接入资源的上行初始BWP配对的下行初始BWP。假设仅仅配置一个，则使用这一个即可。作为一种优选实施例，若网络为特定类型终端配置了单独的上行初始BWP，且其上配置了随机接入资源，则网络也会为特定类型终端配置一个单独的下行初始BWP，其上包含RAR的搜索空间。
S70142，当从SIB1中获取的BWP相关信息包括指示用于常规类型终端的下行初始BWP的第二下行初始BWP信息以及指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，第一下行初始BWP信息所指示的下行初始BWP不具有RAR搜索空间，且从SIB1中获取的BWP相关信息中包括的第二下行初始BWP信息所指示的下行初始BWP满足预设带宽需求时，将下行BWP切换至从SIB1中获取的BWP相关信息中包括的第二下行初始BWP信息所指示的下行初始BWP。满足预设带宽需求，即带宽不会大于特定终端支持的最大带宽。
在本实施例中，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的但不具有RAR搜索空间的下行初始BWP，并指示用于常规类型终端的且满足特定类型终端的预设带宽需求的下行初始BWP，则特定类型终端可以将下行BWP切换至该BWP相关信息指示的用于常规类型终端的下行初始BWP。
S70143，当从SIB1中获取的BWP相关信息包括指示用于常规类型终端的下行初始BWP的第二下行初始BWP信息以及指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，第一下行初始BWP信息所指示的下行初始BWP不具有RAR搜索空间，且从SIB1中获取的BWP相关信息中包括的第二下行初始BWP信息所指示的下行初始BWP不满足预设带宽需求时，将下行BWP切换至从MIB中获取的BWP相关信息中包括的第三下行初始BWP信息所指示的用于常规类型终端的下行初始BWP。
在本实施例中，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的但不具有RAR搜索空间的下行初始BWP，并指示用于常规类型终端的但不满足特定类型终端的预设带宽需求的下行初始BWP，则特定类型终端可以将下行BWP切换至从MIB中获取的BWP相关信息指示的用于常规类型终端的下行初始BWP。
S70144，当从SIB1中获取的BWP相关信息不包括指示用于常规类型终端的下行初始BWP的第二下行初始BWP信息但包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，第一下行初始BWP信息所指示的下行初始BWP不具有RAR搜索空间时，将下行BWP切换至从MIB中获取的BWP相关信息中包括的第三下行初始BWP信息所指示的用于常规类型终端的下行初始BWP。

在本实施例中，若从SIB1中获取的BWP相关信息指示专用于特定类型终端的但不具有RAR搜索空间的下行初始BWP，无论从SIB1中获取的BWP相关信息是否指示用于常规类型终端的下行初始BWP，特定类型终端都可以将下行BWP切换至从MIB中获取的BWP相关信息指示的用于常规类型终端的下行初始BWP。
S7015，当从SIB1中获取的BWP相关信息中包括指示用于常规类型终端的下行初始BWP第二下行初始BWP信息但不包括指示专用于特定类型终端的下行初始BWP的第一下行初始BWP信息，且从SIB1中获取的BWP相关信息中包括的第二下行初始BWP信息所指示的下行初始BWP满足预设带宽需求时，将下行BWP切换至从SIB1中获取的BWP相关信息中包括的第二下行初始BWP信息所指示的下行初始BWP。
在本实施例中，若从SIB1中获取的BWP相关信息仅指示用于常规类型终端的且满足特定类型终端的预设带宽需求的下行初始BWP，但不指示专用于特定类型终端的下行初始BWP，特定类型终端可以将下行BWP切换至从SIB1中获取的BWP相关信息指示的用于常规类型终端的下行初始BWP。
