具体实施方式
下面结合附图及实施例对本申请再作进一步详细的描述。
通常，终端在初始小区接入过程中，会在初始BWP(英文可以表达为initial BWP)内发起随机接入。当处于连接态时，终端在服务小区的激活BWP(激活BWP可以不同于初始BWP)上进行数据收发。
在数据收发过程中，当RRC链路出现问题时，终端需要进行RRC连 接重建，那么在这种情况下，就会存在BWP选择的问题。比如如果终端重建到原服务小区，由于初始BWP和原激活BWP都可以用于发起RRC重建，存在BWP选择问题。
基于此，在本申请的各种实施例中，终端获取用于发起RRC连接重建的BWP相关信息。由于获取了用于发起RRC连接重建的BWP相关信息，这样终端就可以快速选择出BWP进行RRC连接重建，从而能够更快地恢复数据的收发，提高系统性能。
本申请实施例提供了一种BWP的处理方法，应用于终端，如图1所示，该方法包括：
步骤100：确定需要进行RRC连接重建；
这里，实际应用时，当数据收发过程中RRC链路出现问题时，所述终端确定需要进行RRC连接重建。
步骤101：获取BWP相关信息。
这里，所述BWP相关信息用于供所述终端发起RRC连接重建。
需要说明的是：步骤100与101的执行可以不分先后。
在一实施例中，所述终端可以通过接收网络下发的BWP相关信息的方式获取所述BWP相关信息，也可以通过获取规定的BWP相关信息方式得到所述BWP相关信息。
这里，实际应用时，所述网络可以通过RRC连接重配置信令向所述终端下发BWP相关信息，也可以在为所述终端配置BWP时向所述终端下发所述BWP相关信息。
获取所述BWP相关信息后，所述终端可能在所述BWP相关信息对应的BWP上发起RRC重建，也就是说，所述终端在所述BWP相关信息对应的BWP上发起RRC重建或者优先发起RRC重建。
在一实施例中，所述BWP相关信息包含以下信息至少之一：
BWP索引(一个BWP索引)；
多个BWP索引；
频域位置和带宽；
子载波间隔；
循环前缀；
BWP选择门限；
BWP转换定时器；
BWP转换计数器；
比特位图。
其中，实际应用时，BWP索引可以为BWP ID。
当所述BWP相关信息包含BWP索引时，包含的BWP索引可以是初始BWP索引，也可以是非初始BWP索引。其中，初始BWP是终端初始接入网络时获得，由系统广播配置；非初始BWP是终端进入连接态之后， 网络通过RRC信令配置的BWP。当RRC配置的BWP数目小于或等于3个时，BWP ID 0(BWP ID为0)的BWP永远表示初始BWP；当RRC配置的BWP数目大于或等于4个时，BWP ID 0不能指示初始BWP，即这种情况下BWP ID不能指示初始BWP，此时，网络不能通过BWP索引指示终端在初始BWP上发起随机接入，需要明确通知终端在初始BWP上发起随机接入。
当获取了多个BWP索引时，所述终端需要确定尝试RRC重建的BWP的先后顺序。BWP索引在IE中的顺序可以是所述终端RRC重建的BWP的先后顺序，即网络信令指示先后顺序，或者，RRC重建的多个BWP索引对应的BWP的先后顺序可以为规定的终端RRC重建的BWP的先后顺序，即规定先后顺序，或者，RRC重建的多个BWP索引对应的BWP的先后顺序可以为网络通过信令显性通知的终端RRC重建的BWP的先后顺序；或者，RRC重建的多个BWP索引对应的BWP的先后顺序可以通过BWP选择门限确定(实际应用时，可以根据需要确定如何通过BWP选择门限来选择先后顺序，举个例子来说，可以设置一个BWP选择门限，将各BWP的测量值分别与选择门限进行差值，RRC重建时，按照差值大小确定RRC重建的多个BWP索引对应的BWP的先后顺序，差值大的BWP RRC重建时的顺序在前，差值小的BWP RRC重建时的顺序在后；再举个例子，可以设置多个BWP选择门限，多个BWP选择门限有大小之分，将各BWP的测量值与多个BWP选择门限进行比较，从而确定RRC重建的多个BWP索引对应的BWP的先后顺序，比如有3个BWP，可以设置两个选择门限，为第一门限和第二门限，第一门限高于第二门限，高于第二门限的BWP RRC重建时的顺序在前，高于第一门限且低于第二门限的BWP RRC重建时的顺序为第二，低于第二门限的BWP RRC重建时的顺序为最后)。
实际应用时，可以一个或多个索引可以通过多比特指示。具体地，一种方式是：通过N个比特指示BWP索引，比如，00代表BWP ID 0，01代表BWP ID 1(BWP ID为1)，10代表BWP ID 2(BWP ID为2)，00代表BWP ID 3(BWP ID为3)。另一种实现是：通过M比特指示多个BWP索引，比如从最高位(最左位)比特开始，每隔K个比特指示一个BWP索引。其中，M和K是非零整数，M>K。
这里，实际应用时，可以根据需要选择上述一种方式作为所述终端尝试RRC重建的BWP的先后顺序。
所述BWP选择门限包括以下至少之一：
测量用参考信号接收功率；
测量用参考信号与干扰加噪声比；
测量用RSRP；
信道资源使用率；
信道忙时长和/或信道闲时长。
也就是说，所述BWP选择门限包括以下至少之一：
测量用参考信号接收功率门限；
测量用参考信号与干扰加噪声比门限；
测量用RSRP门限；
信道资源使用率门限；
信道忙时长和/或信道闲时长门限。
其中，所述测量用参考信号是指可用于测量的参考符号，比如同步信号/物理广播信道块(SSB，SS/PBCH Block)，信道状态信息参考信号(CSI-RS，CSI Reference Signal)等。
需要说明的是，终端可以根据BWP选择门限自主确定发起RRC重建的BWP。
在一实施例中，所述比特位图为多比特；其中，每个比特对应一个BWP。
在一实施例中，所述BWP转换定时器是所述终端在配置的BWP上发起RRC重建的时长。具体地，所述终端在配置的BWP上发起RRC连接重建请求时会启动该定时器，当定时器超时后，所述终端在配置的BWP上未收到网络针对RRC连接重建请求的反馈时，停止在所述配置的BWP上的等待。
在一实施例中，所述BWP转换计数器是所述终端在配置的BWP上发起RRC重建的次数。具体地，所述终端在配置的BWP上发起RRC连接重建请求时会启动该计数器，当发起RRC连接重建请求的次数达到预设次数，且在配置的BWP上未收到网络针对RRC连接重建请求的反馈时，停止在所述配置的BWP上的等待。
所述比特位图的方式可以为1比特，也可以为多比特。
具体地，当所述比特位图为1比特时，有以下几种方式：
第一种，比特位配置为第一值，所述终端确定在非初始BWP内发起RRC连接重建；比特位配置为第二值或者未配置比特位，所述终端确定不在非初始BWP内发起RRC连接重建；
第二种，比特位配置为第一值，所述终端确定在初始BWP内发起RRC连接重建；比特位配置为第二值或者未配置比特位，所述终端确定不在初始BWP内发起RRC连接重建；
第三种，比特位配置为第一值，所述终端确定在非初始BWP内发起RRC连接重建；比特位配置为第二值或者未配置比特位，所述终端确定在初始BWP内发起RRC连接重建。
从上面的描述可以看出所述比特位图为1比特时，适用于在原服务小区发起RRC连接重建的过程。
所述第一值、第二值可以根据需要进行设置，比如所述第一值可以设置为1，所述第二值设置为0。
实际应用时，可以选择上述一种方式来实现。当然，所述终端事先已 获知配置为第一值、第二值或未配置时各参数的含义。
当所述比特位图为多比特时，每个比特对应一个BWP，比如该比特置为零表示不能在该BWP上发起RRC重建，该比特置为1表示可以在BWP上发起RRC重建。
当所述终端重建到原服务小区时，所述终端确定发起RRC连接重建的BWP为初始BWP外的其它BWP(非初始BWP)，并确定原激活BWP内配置了随机接入相关资源，且原激活BWP内的数据收发未完成时，在所述其它BWP内发起RRC连接重建。
当确定发起RRC连接重建的BWP为初始BWP外的其它BWP，确定原激活BWP内未配置随机接入相关资源，且原激活BWP内的数据收发已完成时，在初始BWP内发起RRC连接重建。
这里，实际应用时，可以规定：所述终端如何选择用于发起RRC连接重建的BWP。
相应地，本申请实施例还提供了一种BWP的处理方法，应用于网络设备(比如基站等)，如图2所示，该方法包括：
步骤200：确定BWP相关信息；
步骤201：向终端下发BWP相关信息。
这里，下发的BWP相关信息用于供所述终端发起RRC连接重建。
当所述比特位图为1比特时，所述网络设备可以有以下几种配置方式：
第一种，配置比特位为第一值，配置为第一值指示所述终端在非初始BWP内发起RRC连接重建；配置比特位为第二值或者未配置比特位，配置的第二值或未配置指示所述终端不在非初始BWP内发起RRC连接重建；
第二种，配置比特位为第一值，配置的第一值指示所述终端在初始BWP内发起RRC连接重建；配置比特位为第二值或者未配置比特位，配置的第二值或未配置指示所述终端不在初始BWP内发起RRC连接重建；
第三种，配置比特位为第一值，配置的第一值指示终端在非初始BWP内发起RRC连接重建；配置比特位为第二值或者未配置比特位，配置的第二值或未配置指示所述终端在初始BWP内发起RRC连接重建。
本申请实施例提供的BWP的处理方法，终端获取BWP相关信息，所述BWP相关信息用于供所述终端发起RRC连接重建，由于获取了用于发起RRC连接重建的BWP相关信息，这样终端就可以快速选择出BWP进行RRC连接重建，从而能够更快地恢复数据的收发，提高系统性能。
下面结合应用实施例对本申请再作进一步详细的描述。
应用实施例一
在本应用实施例中，终端处于连接态。
步骤一：服务小区通过RRC信令通知终端发起RRC重建的BWP索引；
步骤二：当RRC链路出现问题时，终端开启RRC连接重建，进行小区选择；
步骤三：终端判断选择的小区是否是原服务小区；
这里，终端可以通过检测到的主同步信号(PSS)/辅同步信号(SSS)获取小区ID，从而判断选择的小区是否为原服务小区。
步骤四：如果选择的小区为新小区，终端在该新小区的初始BWP上发起RRC重建请求；如果小区选择到原服务小区，终端根据之前接收的原服务小区的RRC信令中的BWP索引判断在哪个BWP上发起RRC重建请求，并在相应的BWP上发起RRC连接重建请求。
假如，原服务小区信令通知终端在原激活BWP(RRC信令中的BWP索引为原激活BWP索引)上发起RRC连接重建请求，那么终端在原服务小区的原激活BWP上发起RRC连接重建请求。
应用实施例二
在本应用实施例中，所述终端处于连接态。
步骤一：服务小区通过RRC信令通知终端发起RRC重建的BWP顺序，即通知了多个BWP索引，且通过信令指示终端RRC重建的BWP的先后顺序；
步骤二：当RRC链路出现问题时，终端开启RRC连接重建，进行小区选择；
步骤三：终端判断选择的小区是否是原服务小区；
这里，终端可以通过检测到的PSS/SSS获取小区ID，从而判断选择的小区是否为原服务小区。
步骤四：如果小区选择到新小区，终端在该新小区的初始BWP上发起RRC重建请求；如果小区选择到原服务小区，终端根据之前接收的原服务小区的信令判断如何发起RRC重建请求，并在相应的BWP上发起RRC连接重建请求。
假如，原服务小区信令通知终端在BWP-1和BWP-3上发起RRC重建请求，并且重建优先级从高到低是：BWP-1>BWP-3，即终端RRC重建的BWP的先后顺序为先在BWP-1上发起RRC连接重建，后在BWP-3上发起RRC连接重建，那么终端首先在原服务小区的BWP-1上发起RRC连接重建请求，如果未成功，则终端尝试在BWP-3上发起RRC连接重建请求。
