请参见图2，为本申请实施例提供的一种配置方法的流程示意图。如图2所示，该配置方法可以包括但不限于如下步骤：
S201、网络设备确定第一配置信息，该第一配置信息用于确定子带对应的保护带宽的起始位置和大小(size)中的至少一项。
在本申请实施例中，保护带宽(guard band)与子带(subband)之间的关系可以包括但不限于如下两种：
第一种关系：保护带宽与子带之间没有重叠部分。
第二种关系：保护带宽与子带之间存在重叠部分，例如，保护带宽包括于子带中。
示例性的，第一种关系可以参见图3所示，第二种关系可以参见图4所示。图3和图4中，灰色填充方块表示保护带宽，白色填充方块表示子带，其中，标记有D的白色填充方块表示链路方向为下行(downlink)的子带，标记有U的白色填充方块表示链路方向为上行(uplink)的子带。在本申请实施例中，不同的子带上可实现不同的D/U配置，即不同子带的链路方向可以相同也可以不同。图4以保护带宽包括于子带，且保护带宽的起始位置与所属子带的起始位置相同为例，即上行子带的起始位置与该上行子带内的保护带宽的起始位置相同。
需要说明的是，图3和图4中所示的3个子带的链路方向为DUD用于举例，每个子带的链路方向可以为上行或下行，示例性的，该3个子带的链路方向还可以为DDD、UUU、UDU、DUU等。还需要说明的是，图3和图4中所示的2个保护带宽的size相同用于举例，不同保护带宽的size可以相同也可以不同，例如，图3、图4中的两个保护带宽的size均为600RB(Resource Block，资源块)，或者，图3、图4中两个保护带宽的size分别为600RB、700RB。可选的，保护带宽所属BWP内不同保护带宽的size相同，或者，保护带宽所属CC(component carrier，载波单元)内不同保护带宽的size相同。在这种情况下，网络设备针对一个CC或一个BWP，仅需一个size，仅可实现对一个CC或一个BWP中的所有保护带宽的size的配置，这样有利于节省配置开销。可选的，一个CC上可以配4个BWP，该4个BWP之间可以存在重叠部分。
可选的，图3和图4所示的3个子带可以包括于一个BWP(Bandwidth Part，部分带宽)中。保护带宽的数量＝子带数量-1。
在一种实现方式中，网络设备在确定保护带宽的起始位置和大小(size)的过程中，可以以CRB(Common Resource Block，公共资源块)或参考RB(Resource Block，资源块)为参照，其中，参考RB可以为保护带宽所属BWP中索引号最低的RB(Resource Block，资源块)，或者参考RB可以为保护带宽所属CC(component carrier，载波单元)中索引号 最低的RB。可选的，在CC(component carrier，载波单元)层面，可以以CRB为参照为每个保护带宽配置起始位置、size。可选的，在BWP层面，可以以RB级别为每个保护带宽配置起始位置、size。示例性的，以保护带宽所属的BWP占用多个RB，且上述参考RB为该多个RB中索引号最小的RB为例，第一配置信息可以包括保护带宽的起始位置占用的RB相对参考RB的偏移量。相应的，终端设备接收到第一配置信息后，可以根据该偏移量以及参考RB的起始位置，确定保护带宽的起始位置。
在5G中，不同的资源可能使用不同的子载波间隔，CRB相当于一个标尺，用于定位这些资源的位置。CRB从系统带宽内的一个参考点开始编号，该参考点被称为PointA。Point A可理解为一个频域上的参考点。需要说明的是，该pointA和参考RB可能是同一个位置，也可能是不同位置，本申请实施例对此不做限定。
在本申请实施例中，第一配置信息可以显式指示保护带宽的起始位置和size中的至少一项，例如，第一配置信息携带保护带宽的起始位置和size的取值。或者，第一配置信息可以隐式指示保护带宽的起始位置和size中的至少一项。
示例性的，在保护带宽与子带之间的关系如图4所示的情况下(即保护带宽的起始位置与该保护带宽对应的子带的起始位置相同)，网络设备可以通过配置子带的起始位置，来指示该子带内的保护带宽的起始位置。此时，第一配置信息可以为用于配置子带的起始位置的信息。示例性的，第一配置信息携带保护带宽的起始位置和终止位置，通过保护带宽的起始位置和终止位置可以隐式指示保护带宽的size。
S202、网络设备向终端设备发送该第一配置信息。相应的，终端设备接收来自网络设备的第一配置信息。
可选的，第一配置信息可以携带于高层信令(如无线资源控制(Radio Resource Control，RRC))中，或者SIB1(System Information Block Type-1，第一类型系统信息块)中，或者第一配置信息可以携带于媒体接入控制-控制单元(Medium Access Control-Control Element，MAC-CE)信令或下行控制信息(Downlink Control Information，DCI)中。可选的，网络设备还可以对保护带宽的起始位置、size进行更新。示例性的，网络设备可以通过RRC消息对保护带宽的起始位置、size进行更新。
S203、终端设备根据第一配置信息确定保护带宽的起始位置和size中的至少一项。
终端设备接收到第一配置信息后，根据该第一配置信息确定保护带宽的起始位置和size中的至少一项。
在一种实现方式中，在保护带宽与子带之间的关系如图4所示的情况下(即保护带宽的起始位置与该保护带宽对应的子带的起始位置相同)，保护带宽的起始位置可以通过该保护带宽所属的子带的起始位置确定，此时，第一配置信息可以仅配置保护带宽的size。示例性的，第一配置信息包括保护带宽的size，并且网络设备向终端设备发送第二配置信息，该第二配置信息用于配置该保护带宽所属子带的起始位置。相应的，终端设备接收该第二配置信息，将保护带宽所属子带的起始位置作为该保护带宽的起始位置，此时，S203的具体实施方式为：终端设备从该第一配置信息中获取保护带宽的size。通过这种方式，在配置了子带的起始位置后，只需要配置保护带宽的size即可，有利于节省配置开销。其中，第二配置信息可以携带于高层信令中。
在一种实现方式中，保护带宽的size可以根据该保护带宽所属BWP的SCS(SubCarrier Spacing，子载波间隔)确定。可选的，SCS与保护带宽的size可以具有对应关系。此时，保护带宽的size为该保护带宽所属BWP的SCS对应的size。换言之，网络设备在配置了BWP的SCS后，不用再显式配置该BWP中的保护带宽的size。终端设备在获知BWP的SCS后，可以将该BWP的SCS对应的size作为该BWP中的保护带宽的size。通过这种方式，网络设备无需再通过第一配置信息指示保护带宽的size，有利于节省配置开销。可选的，网络设备可以通过第三配置信息配置BWP的SCS，此时，第一配置信息可以仅指示保护带宽的起始位置。
示例性的，以SCS包括15kHz、30kHz、60kHz为例，SCS与保护带宽的size间的对应关系可以如表1所示。可选的，SCS与保护带宽的size间的对应关系可以由协议约定，或者，由网络设备向终端设备指示，本申请实施例对此不做限定。
表1 SCS与保护带宽的size间的对应关系
在一种实现方式中，子带的频域位置信息可以根据该子带对应的保护带宽的起始位置和size中的至少一项确定，此时，终端设备可以根据子带对应的保护带宽的起始位置和size中的至少一项确定该子带的频域位置信息。即通过保护带宽的起始位置和size中的至少一项来反推子带的频域位置信息，这样无需额外配置子带的频域位置信息。其中，子带的频域位置信息可以包括起始位置和终止位置中的至少一项，或者，包括起始位置和size中的至少一项。
示例性的，以保护带宽与子带之间的关系如图3所示为例，若终端设备已确定第一个保护带宽和第二个保护带宽的起始位置和size，那么终端设备可以确定第一个保护带宽和第二个保护带宽的起始位置和终止位置。其中，第一个保护带宽的起始位置是第一个子带的结束位置，第一个保护带宽的结束位置是第二个子带的开始位置；第二个保护带宽的起始位置是第二个子带的结束位置，第二个保护带宽的结束位置是第三个子带的开始位置；第一个子带的开始位置是BWP的开始位置，第三个子带的结束位置是BWP的结束位置。其中，第一个保护带宽、第二个保护带宽依次为图3中由下向上的顺序中的第一个、第二个保护带宽，第一个子带、第二个子带、第三个子带依次为图3中由下向上的顺序中的第一个、第二个、第三个子带。
示例性的，以保护带宽与子带之间的关系为前述第一种关系(如参见图3)为例，可通过如下表达式(1)反推子带的起始位置，通过表达式(2)反推子带的终止位置：
其中，s表示子带的索引号；表示索引号为s的子带的频域起始RB的索引号(即 表示子带的起始位置)；表示索引号为0的子带的频域起始RB的索引号。表示第s-1个保护带宽的起始RB的索引号(或表示索引号为s-1的保护带宽的起始RB的索引号)；表示第s-1个保护带宽在频域占用的RB数目(或表示索引号为s-1的保护带宽在频域占用的RB数目)。表达式(1)可理解为通过索引号为s-1的保护带宽的起始RB和在频域占用的RB数目，确定索引号为s的子带的频域起始RB的索引号。其中，索引号为0的子带可以理解为一个BWP或CC中的索引号最小的子带。
其中，表示索引号为s的子带的频域终止RB的索引号(即表示子带的终止位置)；NRB-set-1表示子带的总数，例如表示一个BWP中的子带总数，子带的最大索引号为NRB-set-1；表示索引号为NRB-set-1的子带的频域终止RB的索引号；表示第s个保护带宽的起始RB的索引号(或表示索引号为s的保护带宽的起始RB的索引号)。表达式(2)可理解为通过索引号为s的保护带宽的起始RB，确定索引号为s的子带的频域终止RB。
示例性的，以保护带宽与子带之间的关系如图4所示为例，若终端设备已确定第一个保护带宽和第二个保护带宽的起始位置和size，那么终端设备可以确定第一个保护带宽和第二个保护带宽的起始位置和终止位置。其中，第一个保护带宽的起始位置是第一个子带的结束位置和第二个子带的开始位置；第二个保护带宽的起始位置是第二个子带的结束位置和第三个子带的开始位置；第一个子带的开始位置是BWP的开始位置，第三个子带的结束位置是BWP的结束位置。
在一种实现方式中，若相邻子带的链路方向均为上行，则该相邻子带对应的保护带宽用于上行传输；若相邻子带的链路方向均为下行，则该相邻子带对应的保护带宽用于下行传输。换言之，网络在配置了保护带宽的情况下，终端设备仍可以将配置的保护带宽用于数据传输。配置的保护带宽具体用于上行数据传输还是下行数据传输，可以通过该保护带宽对应的相邻子带的链路方向确定：若相邻2个子带的链路方向相同，则该相邻两个子带对应的保护带宽可用于数据传输，并且该保护带宽用于数据传输的情况下，其链路方向与该相邻2个子带的链路方向相同。保护带宽用于数据传输的情况下，可以认为该保护带宽不存在。若相邻2个子带的链路方向不同，那么该相邻两个子带对应的保护带宽仍然存在，用于防止频带间产生干扰。
示例性的，参见图5所示的4种情况，可用于说明保护带宽是否可用于数据传输。图5中，左边表示网络配置的保护带宽与子带间的关系，右边表示实际的保护带宽与子带间的关系，通过左边到后面的变化，可直观看出保护带宽是否可用于数据传输。具体的，情况1中，保护带宽1可用于上行传输，保护带宽2不可用于数据传输。情况2中，保护带宽1和保护带宽2均可用于下行传输。情况3中，保护带宽1可用于上行传输，保护带宽2不可用于数据传输。情况4中，保护带宽1和保护带宽2均可用于下行传输。
在一种实现方式中，若终端设备未接收到用于配置子带的链路方向的配置信息，则可 以确定该子带的链路方向为预设方向。其中，该预设方向可以为上行或下行。用于配置子带的链路方向的配置信息可以携带于SIB1(System Information Block Type-1，第一类型系统信息块1)中或者其他高层信令中。若SIB1或者其他高层信令没有配置该子带所属BWP或者CC的子带方向信息，终端设备可以默认网络设备配置的子带的链路方向为预设方向。示例性的，子带方向信息缺省时，终端设备可以默认网络设备配置的子带的链路方向均为上行或均为下行，或者，终端设备默认网络设备配置的某个特定的子带(如索引号最小的子带或者索引号最大的子带)为上行或下行，或者，终端设备默认网络设备配置的多个子带的链路方向为预设模式方向。以网络设备配置3个子带为例，预设模式方向可以为DDD、UUU、DUD、UDU等，具体可参见图3、图4所示。此外，以网络设备配置2个子带为例，预设模式方向可以为DD、UU、DU或者UD等。
在一种实现方式中，子带所属的BWP可包括多个链路方向为上行的子带，此时，该多个链路方向为上行的子带中的一个或多个子带上可配置有RO(Physical Random Access Channel occasion，物理随机接入信道机会)资源。示例性的，若一个BWP包括多个链路方向为上行的子带，那么网络设备可以在每个上行子带上均配置RO资源，或者仅在某一个或多个上行子带上配置RO资源。例如在索引号最小的上行子带上配置RO资源。上行子带表示：链路方向为上行的子带。
在一种实现方式中，子带所属的BWP包括多个链路方向为下行的子带，此时，该多个链路方向为下行的子带中的一个或多个子带上可配置有CORESET(Control Resource Set，控制资源集)。示例性的，示例性的，若一个BWP包括多个链路方向为下行的子带，那么网络设备可以在每个下行子带上均配置CORESET，或者仅在某一个或多个下行子带上配置CORESET。例如在索引号最小的下行子带上配置CORESET。下行子带表示：链路方向为下行的子带。
CORESET用于配置PDCCH(Physical Downlink Control Channel，物理下行控制信道)频域上占据的频域资源和时域上占用的OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)符号数等信息。CORESET在频域上可包括多个PRB(Physical Resource Block，物理资源块)，时域上可包括1-3个OFDM符号。
通过本申请实施例，通过配置子带对应的保护带宽，有利于防止数据干扰，从而有利于提高传输性能。
