具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
在现有5G系统及标准中，无线资源控制(RRC，Radio Resource Control)配置载波进行自调度或被调度。自调度，即在当前载波上接收DCI并调度当前载波上的物理下行共享信道(PDSCH，Physical Downlink Shared Channel)或物理上行共享信道(PUSCH，Physical Uplink Shared Channel)。被调度，即在另外一个载波上接收DCI而调度该载波上的PDSCH或PUSCH。当RRC配置一个载波(记为载波C)为被调度时，RRC需要配置载波C的调度载波索引(即由哪个载波调度载波C)并且配置载波C在调度载波中的CIF取值。主调载波上的DCI中的CIF域指示载波C在调度载波中的CIF取值时，则该DCI在载波 C上调度CrossCarrierSchedulingConfig配置CrossCarrierSchedulingConfig信元中schedulingCellId配置调度载波索引，CrossCarrierSchedulingConfig信元中的cifInSchedulingCell配置载波在调度载波中的CIF取值。假设RRC配置载波C由载波A跨载波调度并且配置载波C在调度载波中的CIF取值为1，当载波A上的DCI的CIF域指示的CIF取值为1时，则此DCI在载波C上调度PDSCH或PUSCH。
需要说明的是，DCI格式1_0和0_0(也称为回退下行控制信息fallback DCI)中不能配置CIF域，所以DCI格式1_0和0_0只能用于自调度而不能用于跨载波调度；DCI格式0_1、DCI格式0_2、DCI格式1_1和DCI格式1_2(也称为非回退下行控制信息non-fallback DCI)中可以配置CIF域，它们可以用于跨载波调度。
当RRC配置载波为自调度时，DCI格式1_0只能用于调度本载波上的PDSCH，DCI格式0_0只能用于调度本载波上的PUSCH，DCI格式1_1且CIF＝0时和DCI格式1_2且CIF＝0时用于调度本载波上的PDSCH，DCI格式0_1且CIF＝0时和DCI格式0_2且CIF＝0时用于调度本载波上的PUSCH。当RRC配置载波为被调度时，调度载波上的DCI(DCI格式0_1、DCI格式0_2、DCI格式1_1和DCI格式1_2)的CIF域指示为该载波配置的在调度载波中的CIF取值时表示跨载波调度该载波，一个CIF取值只能对应一个载波。目前一个载波只能配置为自调度或被调度，不能同时被配置为自调度和被调度。目前主小区只能配置为自调度，因此导致在DSS时PDCCH容量受限，导致5G系统传输控制信令的负载较高。
相关技术中，对于新技术与旧技术部署在相同的频谱的情况，新技术中自调度与跨载波调度之间的切换，是通过高层信令，比如RRC信令指示的，切换速度比较慢。
针对这一问题，本公开实施例提供了调度方式的切换方法及装置。
图1为本公开实施例提供的一种调度方式的切换方法的流程示意图，该方法由终端执行，通过基于DCI进行调度方式的切换，以实现在自调度和跨载波调度之间快速切换，可以更好的适应链路质量和负载的变化，提高系统资源的利用率。
如图1所示，该调度方式的切换方法包括以下步骤：
步骤101，基于获取的第一DCI，进行调度方式的切换，其中，第一DCI用于指示终端的目标调度方式。
本公开中，终端可获取基站发送的DCI，为了便于区分，这里称为第一DCI。其中，第一DCI用于指示终端的目标调度方式。
调度方式，可以是指下行控制信道与数据信道，是在同一载波上，还是在不同载波上。调度方式可包括自调度和跨载波调度，自调度可以指下行控制信道与数据信道在同一个载波上，跨载波调度可以指下行控制信道与数据信道在不同的载波上。
终端基于获取的第一DCI，根据第一DCI，进行调度方式的切换。比如，第一DCI指示终端的目标调度方式为自调度，那么终端可从当前的调度方式切换为自调度方式。
本公开实施例的调度方式的切换方法，通过根据DCI指示的终端的目标调度方式，进行调度方式的切换，实现了在自调度和跨载波调度之间快速切换，可以更好的适应链路质量和负载的变化，提高了系统资源的利用率。
图2为本公开实施例提供的另一种调度方式的切换方法的流程示意图。该方法由终端执行，通过基于第一DCI指示的调度方式与当前调度方式是否不相同，进行调度方式的切换。
如图2所示，该调度方式的切换方法包括：
步骤201，响应于获取的第一DCI中指示的目标调度方式与当前调度方式不同，进行调度方式的切换；或者，响应于获取的第一DCI中指示的目标调度方式与当前调度方式相同，保持当前的调度方式。
本公开中，终端可获取基站发送的第一DCI，其中，第一DCI用于指示终端的目标调度，第一DCI中可包括至少一个终端的目标调度方式。其中，调度方式可包括自调度和跨载波调度。
可选地，终端可在CSS内获取第一DCI，或者，在USS内获取第一DCI。
可选地，第一DCI的长度可以与其他任一DCI的长度不同。
由于终端的盲检次数与DCI的长度有关，为了不增加终端的盲检次数，可选地，第一DCI的长度可与回退DCI的长度相同。由于第一DCI的长度，与回退DCI的长度相同，因此不会增加终端的盲检次数。
终端可将第一DCI指示的目标调度方式与当前调度方式进行比较，终端响应于目标调度方式与当前调度方式不同，将当前调度方式切换为目标调度方式，以实现调度方式的切换。
或者，终端响应于第一DCI中指示的目标调度方式与当前调度方式相同，继续保持当前的调度方式。
比如，第一DCI中指示的目标调度方式为跨载波调度，终端当前的调度方式为自调度，那么终端从自调度切换为跨载波调度。若终端当前的调度方式为跨载波调度，那么终端继续保持跨载波调度。
又如，第一DCI中指示的目标调度方式为自调度，终端当前的调度方式为跨载波调度，那么终端从跨载波调度切换为自调度。若终端当前的调度方式为自调度，那么终端继续保持自调度。
本公开实施例的调度方式的切换方法，通过基于DCI指示的调度方式与当前调度方式是否不相同，确定是否进行调度方式的切换，实现了在自调度和跨载波调度之间快速切换，可以更好的适应链路质量和负载的变化，提高了系统资源的利用率。
图3为本公开实施例提供的另一种调度方式的切换方法的流程示意图。该方法由终端执行，通过响应于第一DCI中的RNTI为终端所在组的RNTI，基于第一DCI中与终端对应的目标比特位的当前取值，确定目标调度方式，根据目标调度方式和当前调度方式，确定是否进行调度方式的切换。
如图3所示，该调度方式的切换方法包括：
步骤301，基于终端对应的目标RNTI，获取第一DCI。
本公开中，终端可获取基站发送的终端分组指示消息，通过对获取的终端分组指示消息进行解析，确定终端所在的组对应的目标RNTI。其中，该终端获取的终端分组指示消息中可以是只指示了该终端所在组的目标RNTI，也可包括多个终端所在组的目标RNTI，该终端可根据终端标识与RNTI之间的映射关系，确定本身对应的目标RNTI。
基站可先用RNTI对附加在第一DCI之后CRC码进行加扰，将附接(attach)有经过加扰后CRC的第一DCI发送给终端。终端可对公共控制信道上的包含有DCI的下行传输进行盲检，以根据其对应的目标RNTI，得到与该终端相对应的DCI，即第一DCI。例如，终端利用与自己相关联的目标RNTI，对公共控制信道上的下行传输中的被加扰的CRC进行解扰，以得到解扰后的CRC，并利用该CRC对DCI进行校验。如果校验成功，则接收该下行传输。而如果校验失败，则丢弃该下行传输。
可选地，终端可在CSS内获取第一DCI，或者，在USS内获取第一DCI。
可选地，第一DCI的长度可以与其他任一DCI的长度不同。
由于终端的盲检次数与DCI的长度有关，为了不增加终端的盲检次数，可选地，第一DCI的长度可与回退DCI的长度相同。由于第一DCI的长度，与回退DCI的长度相同，因此不会增加终端的盲检次数。
步骤302，根据第一DCI中与终端对应的目标比特位的当前取值，确定终端的目标调度方式。
在本公开中，第一DCI中可包括与一个或多个终端分别对应的比特位，比特位的取值可用于指示对应终端的目标调度方式。也就是说，第一DCI中可包括至少一个终端的目标调度方式。
第一DCI中每个终端对应的目标比特位，可以是预先约定的，比如可以是标准预先规定，也可以是终端根据基站发送的指示其目标特位的指令确定的。那么，终端可确定第一DCI中与其对应的目标比特位。
本公开中，第一DCI中与终端对应的目标比特位的取值不同，可表示不同的调度方式。那么，终端可根据目标比特位的当前取值，确定终端的目标调度方式。
比如，取值为0表示自调度，取值为1表示跨载波调度，若第一DCI中某终端对应的目标比特位的当前取值为1，可以确定该终端的目标调度方式为跨载波调度。
需要说明的是，比特位的取值为0或1及对应的调度方式，仅是示例，可根据实际需要设置，本实施例对此不作限定。
在一种实施方式中，比特位的取值可以仅仅指示相应的终端是否应该切换调度方式。例如，比特位取值为0，可以指示保持当前的调度方式。而比特位取值为1，可以指示切换调度方式。
在一种实施方式中，目标比特位可以为多个比特位，以表示特定数量的调度方式。例如，目标比特位为2位，00表示第一调度方式，01表示第二调度方式，10表示第三调度方式，11表示第四调度方式，以此类推。
步骤303，响应于获取的第一DCI中指示的目标调度方式与当前调度方式不同，进行调度方式的切换；或者，响应于获取的第一DCI中指示的目标调度方式与当前调度方式相同，保持当前的调度方式。
本公开中，步骤303可以分别采用本公开的各实施例中的任一种方式实现，本公开实施例并不对此作出限定，也不再赘述。

如图4所示，该调度方式的切换方法包括：
步骤401，响应于获取的第一DCI中指定信息域的取值为第一指定值，确定第一DCI中与终端对应的目标比特位的当前取值。
由于第一DCI与其他DCI的长度相同，为了区分第一DCI与其他DCI，本公开中，第一DCI中的指定信息域的取值可以为指定值，为了便于区分，这里称为第一指定值。其中，第一指定值可根据需要设定。
本公开中，第一DCI中可包括与一个或多个终端分别对应的比特位，比特位的取值可用于指示对应终端的目标调度方式。终端可响应于获取的第一DCI中指定信息域的取值为第一指定值，确定第一DCI中与终端对应的目标比特位的当前取值。

可选地，每个终端可对应DCI中的一个比特位。比如，终端对应比特位的取值为0，表示自调度；终端对应的比特位的取值为1，表示跨载波调度。
在一种实施方式中，比特位的取值也可以仅仅指示相应的终端是否应该切换调度方式。例如，比特位取值为0，可以指示保持当前的调度方式。而比特位取值为1，可以指示切换调度方式。
在一种实施方式中，目标比特位也可以为多个比特位，以表示特定数量的调度方式。例如，目标比特位为2位，00表示第一调度方式，01表示第二调度方式，10表示第三调度方式，11表示第四调度方式，以此类推。
方式二：使用新的DCI格式进行跨载波调度指示，在主小区/主辅小区的CSS上，或者在辅小区的USS上发送DCI。其中，DCI格式的设计方法如下：
一是，可定义一种新的DCI格式,确保该DCI的比特数与已有DCI格式的比特数不同。
二是，可定义一种新的DCI格式，使用与已有的某个DCI格式相同的比特数，并将新的DCI信息域设置为指定值(记为第一指定值)，以表征新的DCI格式。
