与现有技术相比，本发明实施例的技术方案具有以下有益效果：
在本发明实施例中，配置部分带宽中至少一部分子带的传输方向，配置并发送所述子带方向指示信息，可以使得终端确定部分带宽中各个子带的传输方向，从而在同一时刻，实现多个子带之间的传输方向不完全相同，有助于适应灵活多变的上下行业务场景，填补现有技术中的空白。
进一步，相邻子带之间均添加有第一保护子带，所述子带方向指示信息包含各个有效保护子带的指示信息，由于有效保护子带的数量少于等于子带的数量，可以采用更少的比特指示子带方向，减少子带方向指示信息的信令开销。
进一步，配置传输方向为上行的子带相邻，配置传输方向为下行的子带相邻，其中，仅有两个相邻的子带传输方向不同，从而在传输方向不同的相邻子带之间添加第二保护子带时，可以减少第二保护子 带的数量至仅添加一个，相比于添加多个保护子带，有更多的频域资源用于传输数据。
进一步，配置频域资源分配域，所述频域资源分配域用于指示PUSCH所属的子带中的PUSCH的起点和长度，或者用于指示PDSCH所属的子带中的PDSCH的起点和长度，可以使得终端确定PUSCH的起点和长度或者PDSCH的起点和长度。
进一步，在终端的剩余能量大于等于第一阈值时，设置使能参数的状态为使能，才配置部分带宽中至少一部分子带的传输方向，否则继续沿用现有技术中在同一时刻多个子带之间的传输方向相同的技术方案。由于采用本发明实施例的方案需要耗费一定的能量，因此仅在终端剩余能量较大时执行，在终端剩余能量较小时不执行，有助于提高终端的持久性。

在本发明实施例中，配置部分带宽中至少一部分子带的传输方向，配置并发送所述子带方向指示信息，可以使得终端确定部分带宽中各个子带的传输方向，从而在同一时刻，实现多个子带之间的传输方向不完全相同，有助于适应灵活多变的上下行业务场景，填补现有技术中的空白。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
参照图1，图1是本发明实施例中一种数据传输方向的指示方法的流程图。所述数据传输方向的指示方法可以用于基站，还可以包括步骤S11至步骤S13：
步骤S11：配置部分带宽中至少一部分子带的传输方向，其中，各个子带之间独立配置传输方向为上行或下行；
步骤S12：配置子带方向指示信息，所述子带方向指示信息用于指示各个子带的传输方向；
步骤S13：发送所述子带方向指示信息。
可以理解的是，在具体实施中，所述方法可以采用软件程序的方式实现，该软件程序运行于芯片或芯片模组内部集成的处理器中。
在步骤S11的具体实施中，部分带宽(Bandwidth Part，BWP)中的各个子带之间可以独立配置传输方向。
参照图2，图2是本发明实施例中第一种上下行数据传输的工作场景示意图。
如图2所示，终端或者基站可以在不同的子带上面实现不同的上行传输/下行传输。其中，子带23和子带24占用相同的频域资源，可以视为同一个子带，以下基于不同的时刻T1和T2进行描述。
例如在时刻T1，部分带宽中的子带21、子带22以及子带23同时传输，其中，子带21和子带23的传输方向为下行，子带22的传输方向为上行。在时刻T2，部分带宽中的子带21、子带22以及子带24同时传输，其中，子带21的传输方向为下行，子带22和子带24的传输方向为上行。
需要指出的是，在现有技术中，在同一时刻，同一部分带宽中的多个子带之间的传输方向是相同的，以图2中的子带21、子带22以及子带23为例，则在现有技术中，子带21至子带23的传输方向需要均为上行，或均为下行。
进一步地，配置部分带宽中至少一部分子带的传输方向的步骤可以包括：配置除部分带宽中第一子带之外的其他子带的传输方向；其中，所述第一子带的传输方向为预定义的传输方向。
例如在图2中，可以默认各个部分带宽中的第一子带为固定下行传输或者上行传输，所述第一子带可以为子带索引号最小的子带，例如子带21，其中，子带21的传输方向例如可以默认为下行传输。或者，默认其他一个或多个索引号的子带固定为只能进行下行传输或者上行传输。
其中，所述默认为下行传输或者上行传输的子带可以称为锚子带(anchor subband)。
在本发明实施例中，可以通过通信协议预定义第一子带的传输方向，还可以由发送端通过高层信令或者媒体接入控制(Medium Access Control，MAC)控制单元(MAC Control Element，CE)或者下行控制信息(Downlink Control Information，DCI)通知接收端第一子带的传输方向。
继续参照图1，在步骤S12的具体实施中，配置子带方向指示信息，所述子带方向指示信息用于指示各个子带的传输方向。
在本发明实施例的一种具体实施方式中，在所述部分带宽中，相邻子带之间添加有第一保护子带；所述配置子带方向指示信息包括：确定位于传输方向不同的相邻子带之间的所述第一保护子带，记为有效保护子带；其中，所述子带方向指示信息包含各个有效保护子带的指示信息。
参照图3，图3是本发明实施例中第二种上下行数据传输的工作场景示意图。
具体地，部分带宽可以包含子带31、子带32、子带33以及子带34，在相邻子带之间均添加有第一保护子带。
由于子带31、子带32之间的传输方向不同，因此子带31、子带32之间的第一保护子带35为有效保护子带，同理，子带32、子带33之间的第一保护子带36也为有效保护子带，子带33、子带34之间的第一保护子带37也为有效保护子带。
其中，所述子带方向指示信息包含各个有效保护子带的指示信息。
更进一步地，采用所述有效保护子带的序号作为所述有效保护子带的指示信息；或者，采用与所述有效保护子带相邻，且频域资源小于所述有效保护子带的子带的序号作为所述有效保护子带的指示信 息；或者，采用与所述有效保护子带相邻，且频域资源大于所述有效保护子带的子带的序号作为所述有效保护子带的指示信息。
以有效保护子带35为例，与所述有效保护子带35相邻，且频域资源小于所述有效保护子带35的是子带31，与所述有效保护子带35相邻，且频域资源大于所述有效保护子带35的是子带32。因此，可以采用有效保护子带35的序号作为有效保护子带35的指示信息，还可以采用子带31的序号作为有效保护子带35的指示信息，还可以采用子带32的序号作为有效保护子带35的指示信息。
需要指出的是，虽然图3示出的工作场景中，有效保护子带的数量与第一保护子带的数量一致，然而在其他工作场景中，有效保护子带的数量可以小于第一保护子带的数量。
结合参照图4和图5，图4是本发明实施例中第三种上下行数据传输的工作场景示意图，图5是本发明实施例中第四种上下行数据传输的工作场景示意图。
在图4和图5中，由于相邻子带之间添加有第一保护子带，因此第一保护子带的数量均为3个。
在图4中，由于子带42、子带43之间的传输方向相同，因此子带42、子带43之间的第一保护子带(图未示)不是有效保护子带，图4中有效保护子带的数量仅为2个。
在图5中，由于仅子带52、子带53之间的传输方向不同，因此只有子带52、子带53之间的第一保护子带是有效保护子带，图5中有效保护子带的数量仅为1个。
在本发明实施例中，相邻子带之间均添加有第一保护子带，所述子带方向指示信息包含各个有效保护子带的指示信息，由于有效保护子带的数量少于等于子带的数量，可以采用更少的比特指示子带方向，减少子带方向指示信息的信令开销。
可选的，如果相邻子带的传输方向相同，那么它们之间的保护子 带可以认为是无效的，所述无效保护子带可以用于通信信息传输。从而可以采用更多频域资源进行通信信息传输。
可选的，如果相邻子带的传输方向相同，那么它们之间的保护子带仍然不可以用于通信信息传输。
在上述图3至图5中，所述锚子带可以为子带索引号最小的子带，其传输方向为默认方向，如图中均为上行。
在本发明实施例的另一种具体实施方式中，在所述部分带宽中，传输方向不同的相邻子带之间添加有第二保护子带；所述配置子带方向指示信息包括：配置所述子带方向指示信息包含各个第二保护子带的指示信息。
继续参照图3，在本发明实施例中第二种上下行数据传输的工作场景示意图中，部分带宽可以包含子带31、子带32、子带33以及子带34，由于子带31、子带32之间的传输方向不同，因此子带31、子带32之间添加有第二保护子带35，同理，子带32、子带33之间添加有第二保护子带36，子带33、子带34之间添加有第二保护子带37。
其中，所述子带方向指示信息包含各个第二保护子带的指示信息。
更进一步地，采用所述第二保护子带的序号作为所述第二保护子带的指示信息；或者，采用与所述第二保护子带相邻，且频域资源小于所述第二保护子带的子带的序号作为所述第二保护子带的指示信息；或者，采用与所述第二保护子带相邻，且频域资源大于所述第二保护子带的子带的序号作为所述第二保护子带的指示信息。
以第二保护子带35为例，与所述第二保护子带35相邻，且频域资源小于所述第二保护子带35的是子带31，与所述第二保护子带35相邻，且频域资源大于所述第二保护子带35的是子带32。因此，可以采用第二保护子带35的序号作为第二保护子带35的指示信息，还 可以采用子带31的序号作为第二保护子带35的指示信息，还可以采用子带32的序号作为第二保护子带35的指示信息。
继续参照图4和图5，在图4中，由于子带42、子带43之间的传输方向相同，因此子带42、子带43之间没有第二保护子带，图4中第二保护子带的数量仅为2个。
在图5中，由于仅子带52、子带53之间的传输方向不同，因此只有子带52、子带53之间有第二保护子带，图5中第二保护子带的数量仅为1个。
在本发明实施例中，相邻子带之间均添加有第一保护子带，所述子带方向指示信息包含各个有效保护子带的指示信息，由于有效保护子带的数量少于等于子带的数量，可以采用更少的比特指示子带方向，减少子带方向指示信息的信令开销。
进一步地，配置部分带宽中至少一部分子带的传输方向的步骤可以包括：配置传输方向为上行的子带相邻，配置传输方向为下行的子带相邻；其中，仅有两个相邻的子带传输方向不同。
在前述另一种具体实施方式为例，在图3至图5中，均包含两个传输方向为上行的子带以及两个传输方向为下行的子带，然而图3中需要添加3个第二保护子带，图4中需要添加2个第二保护子带，图5中需要添加1个第二保护子带。其中，图5即为传输方向为上行的子带相邻，传输方向为下行的子带相邻，仅有两个相邻的子带传输方向不同的配置方式。
在本发明实施例中，配置传输方向为上行的子带相邻，配置传输方向为下行的子带相邻，其中，仅有两个相邻的子带传输方向不同，从而在传输方向不同的相邻子带之间添加第二保护子带时，可以减少第二保护子带的数量至仅添加一个，相比于添加多个保护子带，有更多的频域资源用于传输数据。
进一步地，在配置部分带宽中至少一部分子带的传输方向之前， 所述方法还包括：确定需要改变所述部分带宽中的至少一个子带的传输方向。
更进一步地，确定需要改变所述部分带宽中的至少一个子带的传输方向的步骤可以包括：根据终端的上行缓冲区状态报告(Buffer State Report，BSR)，确定需要进行上行传输的子带个数；如果需要进行上行传输的子带个数与所述部分带宽中的传输方向为上行的子带的个数不一致，则确定需要改变所述部分带宽中的至少一个子带的传输方向。
参照图6，图6是本发明实施例中第五种上下行数据传输的工作场景示意图。
在时刻T之前，部分带宽中的传输方向为上行的子带的个数为3个。
可以根据终端的BSR确定需要进行上行传输的子带个数。具体来说，不同的BSR可以对应着不同的上行传输的子带个数。如果需要进行上行传输的子带个数为2个，则需要进行上行传输的子带个数(即2个)与所述部分带宽中的传输方向为上行的子带的个数(即3个)不一致，此时需要改变所述部分带宽中的至少一个子带的传输方向，如在T时刻之后，将其中一个子带(例如子带63)的传输方向从上行转为下行。
进一步地，可以采用常规方式，根据终端的BSR确定需要进行上行传输的子带个数，本发明实施例对此不作限制。
继续参照图1，在步骤S12之前，所述方法还可以包括：确定是否存在终端待上报的物理上行链路共享通道(Physical Uplink Shared Channel，PUSCH)和/或待发送的下行共享物理信道(Physical Downlink Share Channel，PDSCH)；如果存在，则配置用于传输PUSCH和/或PDSCH的子带；配置频域资源分配域(Frequency Domain Resource Allocation，FDRA)，所述频域资源分配域用于指示PUSCH 所属的子带中的PUSCH的起点和长度，或者用于指示PDSCH所属的子带中的PDSCH的起点和长度。
在步骤S13中，发送所述子带方向指示信息的步骤可以包括：当发送所述子带方向指示信息时，一并发送所述频域资源分配域。
其中，所述频域资源分配域可以包含PUSCH所属的子带中的PUSCH的起点和长度，或者可以包含所述PUSCH所属的子带中的PUSCH的起点和终点，或者可以包含所述PUSCH所属的子带中的PUSCH的其他适当信息；所述频域资源分配域可以包含PDSCH所属的子带中的PDSCH的起点和长度，或者可以包含所述PDSCH所属的子带中的PDSCH的起点和终点，或者可以包含所述PDSCH所属的子带中的PDSCH的其他适当信息。
在本发明实施例中，配置频域资源分配域，所述频域资源分配域用于指示PUSCH所属的子带中的PUSCH的起点和长度，或者用于指示PDSCH所属的子带中的PDSCH的起点和长度，可以使得终端确定PUSCH的起点和长度或者PDSCH的起点和长度。
进一步地，配置频域资源分配域的步骤可以包括全部配置或部分配置。
在本发明实施例的一种具体实施方式中，配置频域资源分配域的步骤可以包括：为每个用于传输PUSCH和/或PDSCH的子带配置频域资源分配域，可以更好地增强频域资源分配域，尤其是更好地支持非连续频域资源分配域。
在本发明实施例的另一种具体实施方式中，配置频域资源分配域的步骤可以包括：如果仅存在终端待上报的PUSCH，则为每个传输方向为上行的子带配置所述频域资源分配域；如果仅存在待发送的PDSCH，则为每个传输方向为下行的子带配置所述频域资源分配域；如果同时存在终端待上报的PUSCH以及待发送的PDSCH，则为所有子带配置所述频域资源分配域。
在本发明实施例中，在判断到仅存在终端待上报的PUSCH或仅存在待发送的PDSCH时，仅为单个传输方向的子带配置所述频域资源分配域，可以在更好地增强频域资源分配域、支持非连续频域资源分配域的同时，减少配置频域资源分配域的数量。
在本发明实施例中，配置部分带宽中至少一部分子带的传输方向，配置并发送所述子带方向指示信息，可以使得终端确定部分带宽中各个子带的传输方向，从而在同一时刻，实现多个子带之间的传输方向不完全相同，有助于适应灵活多变的上下行业务场景，填补现有技术中的空白。
进一步地，在配置部分带宽中至少一部分子带的传输方向之前，所述方法还可以包括：确定使能参数的状态为使能；其中，所述使能参数用于指示是否配置所述部分带宽中至少一部分子带的传输方向。
具体地，可以引入使能参数，其参数值指示使能(enable)或不使能(disable)。
当使能参数指示不使能时，不会有指示信息指示传输方向为上行或下行，例如可以仅设置时隙配置(slot configuration)的配置，此时可以自然参照时隙配置(slot configuration)的配置信息进行实施。其中，所述时隙配置可以指示时隙或者时隙内每个符号的传输方向是上行还是下行。
当使能参数指示使能时，可以有指示信息指示传输方向为上行或下行，还可以设置时隙配置(slot configuration)的配置。
其中，所述指示信息可以精确到各个子带的传输方向为上行或下行，那么在各个子带上，可以采用指示信息覆盖时隙配置的配置信息。
更进一步地，在确定使能参数的状态为使能之前，所述方法还可以包括：如果所述终端的剩余能量大于等于第一阈值，则设置所述使能参数的状态为使能；如果所述终端的剩余能量小于所述第一阈值，则设置所述使能参数的状态为不使能。
在本发明实施例中，在终端的剩余能量大于等于第一阈值时，设置使能参数的状态为使能，才配置部分带宽中至少一部分子带的传输方向，否则继续沿用现有技术中在同一时刻多个部分带宽之间的传输方向相同的技术方案。由于采用本发明实施例的方案需要耗费一定的能量，因此仅在终端剩余能量较大时执行，在终端剩余能量较小时不执行，有助于提高终端的持久性。
进一步地，接收所述子带方向指示信息的信令可以选自：组通用下行指示信息(Downlink Control Information，DCI)、终端专用DCI、无线资源控制(Radio Resource Control，RRC)、介质访问控制-控制元件(Media Access Control-Control Element，MAC-CE)。
参照图7，图7是本发明实施例中另一种数据传输方向的指示方法的流程图。所述另一种数据传输方向的指示方法可以用于终端，还可以包括步骤S71至步骤S72：
步骤S71：接收子带方向指示信息，所述子带方向指示信息用于指示部分带宽中的各个子带的传输方向为上行或下行；
步骤S72：根据子带方向指示信息，确定所述部分带宽中各个子带的传输方向。
其中，各个子带之间独立配置传输方向为上行或下行。
可以理解的是，在具体实施中，所述方法可以采用软件程序的方式实现，该软件程序运行于芯片或芯片模组内部集成的处理器中。
进一步地，在所述部分带宽中，第一子带的传输方向为预定义的传输方向。
进一步地，相邻子带之间添加有第一保护子带，位于传输方向不同的相邻子带之间的所述第一保护子带，记为有效保护子带，所述子带方向指示信息包含各个有效保护子带的指示信息；根据子带方向指示信息，确定所述部分带宽中各个子带的传输方向包括：根据是否存在与所述第一子带相邻的有效保护子带，确定与所述第一子带相邻的 第二子带的传输方向与所述第一子带的传输方向是否相同，并确定所述第二子带的传输方向；依次根据是否存在与第i子带相邻的有效保护子带，确定与所述第i子带相邻的第i+1子带的传输方向与所述第i子带的传输方向是否相同，并确定所述第i+1子带的传输方向；其中，i大于等于2，且i为正整数。
进一步地，所述有效保护子带的指示信息为所述有效保护子带的序号；或者，所述有效保护子带的指示信息为与所述有效保护子带相邻，且频域资源小于所述有效保护子带的子带的序号；或者，所述有效保护子带的指示信息为与所述有效保护子带相邻，且频域资源大于所述有效保护子带的子带的序号。
进一步地，传输方向不同的相邻子带之间添加有第二保护子带，所述子带方向指示信息包含各个第二保护子带的指示信息；根据子带方向指示信息，确定所述部分带宽中各个子带的传输方向包括：根据是否存在与所述第一子带相邻的第二保护子带，确定与所述第一子带相邻的第二子带的传输方向与所述第一子带的传输方向是否相同，并确定所述第二子带的传输方向；依次根据是否存在与第i子带相邻的第二保护子带，确定与所述第i子带相邻的第i+1子带的传输方向与所述第i子带的传输方向是否相同，并确定所述第i+1子带的传输方向；其中，i大于等于2，且i为正整数。
进一步地，所述第二保护子带的指示信息为所述第二保护子带的序号；或者，所述第二保护子带的指示信息为与所述第二保护子带相邻，且频域资源小于所述第二保护子带的子带的序号；或者，所述第二保护子带的指示信息为与所述第二保护子带相邻，且频域资源大于所述第二保护子带的子带的序号。
进一步地，接收所述子带方向指示信息的信令选自：组通用DCI、终端专用DCI、RRC、MAC-CE。
进一步地，所述方法还可以包括：接收所述子带方向指示信息时，一并接收配置频域资源分配域，所述频域资源分配域用于指示 PUSCH所属的子带中的PUSCH的起点和长度，或者用于指示PDSCH所属的子带中的PDSCH的起点和长度；根据所述配置频域资源分配域确定PUSCH的起点和长度，或者，根据所述配置频域资源分配域确定PDSCH的起点和长度。
