为了解决上述问题，本申请实施例提供了一种无线通信的方法，该方法在支持3个或3个以上频带的通信系统中，通过对终端设备和网络设备频带切换的时间间隔以及切换规则进行了规定，解决了现有的频带切换机制无法支持3个或3个以上的频带切换的问题。
本申请实施例提供的通信方法可以应用于网络设备与终端设备的交互中。该终端设备支持工作在N个频带，N个频带之间的切换对应至少两个切换间隔，且至少两个切换间隔对应的切换时长不同，其中，所述N为大于或等于3的正整数。
例如，当N为3时，终端设备支持工作在3个频带(如band1、band2和band3)，该3个频带之间的切换对应至少两个切换间隔(如包括第一切换间隔和第二切换间隔)。作为一个示例，第一切换间隔可以为band1切换到band2的切换间隔，第二切换间隔可以为band2切换到band3的切换间隔。作为另一个示例，第一切换间隔可以为band1切换到band2的切换间隔，第二切换间隔可以为band1切换到band3的切换间隔。在上述示例中，第一切换间隔和第二切换间隔对应的切换时长不同。第一切换间隔的切换时长可以大于第二切换间隔的切换时长，也可以小于第二切换间隔的切换时长。
下文将结合图2，站在终端设备和网络设备交互的角度对本申请实施例的通信方法的流程进行介绍。
图2所述的通信方法包括步骤S210和步骤S220。
在步骤S210，终端设备接收调度信息。其中，终端设备可以为任意一种前文所述的终端设备。
调度信息可以由网络设备发送。该网络设备例如可以是接入网设备或无线接入网设备，如网络设备可以是基站。
在步骤S220，终端设备根据调度信息切换到对应的频带。
终端设备可以根据接收到的调度信息将当前频带切换到对应的频带(也可以称为目标频带)，其中目标频带属于终端设备支持的N个频带。
作为一种实现方式，N个频带可以属于一个或多个频带组合。也就是说，该N个频带可以是一个或多个频带组合中的频带。
在一些实施例中，一个频带组合最多包含两个频带。
在一些实施例中，该一个或多个频带组合可以由网络设备配置和/或由终端设备向网络设备上报。
例如，该一个或多个频带组合可以由终端设备上报。在该示例中，终端设备可以将容易切换的频带(如频点相邻的频带，或经常同时调用的频带)放在一个频带组合里，并将切换复杂的频带(如频点距离较远的频带，或不经常同时调用的频带)放在不同的频带组合里。进一步地，在终端设备上报频带组合之前，可以接收网络设备的指示信息，指示网络设备建议的频带组合。
又如，该一个或多个频带组合可以由网络设备配置。在该示例中，网络设备可以根据调度需求来确定频带组合。例如，经常调用的频带或组合调用的频带放在一个频带组合里，不常组合调用的频带放在不同的频带组合里。进一步地，在网络设备配置频带组合之前，可以接收终端设备的指示信息，指示终端设备建议的频带组合。
在一些实施例中，频带组合内的频带的切换对应第一切换间隔或切换间隔为0。频带组合间的频带的切换对应第二切换间隔。
在一些实施例中，如果调度信息对应的频带(即调度信息调度的载波或数据所在的频带)属于终端设备的当前频带组合，则终端设备切换所需要的时间小于或等于第一切换间隔或切换间隔为0。
在一些实施例中，如果调度信息对应的频带不属于当前频带组合，则终端设备切换所需要的时间小于或等于第二切换间隔。
在一些实施例中，第一切换间隔与第二切换间隔对应不同的切换时长。
在一些实施例中，第一切换间隔可以小于第二切换间隔。
在一些实施例中，调度信息的发送和调度数据开始传输之间的时间间隔至少大于或等于终端设备切换到目标频带的切换间隔，以确保终端设备具有充足的处理时间，避免数据丢失。该切换间隔可以大于或等于0。或者，该切换间隔可以终端设备当前使用的切换间隔。
在一些实施例中，第一切换间隔对应的时长可以包括以下中的一种或多种：35微秒，140微秒，以及210微秒。
在一些实施例中，第一切换间隔可以基于终端的能力确定。
在一些实施例中，第二切换间隔对应的切换时长可以基于第一参数确定。第一参数例如可以是基于子载波间隔确定的参数。例如，第一参数可以为μ。μ可以用于确定子载波的间隔，例如，当μ等于0时，子载波间隔为15kHz；当μ等于1时，子载波间隔为30kHz；当μ等于2时，子载波间隔为60kHz。
表1给出了根据第一参数确定第二切换间隔的一种可能的方法。
Figure PCTCN2022122761-appb-000001
参见表1，第二切换间隔的切换时长对应的数量可以指正交频分复用(orthogonal frequency division multiplexing，OFDM)符号的数量。例如，如果终端设备的第一切换间隔对应的时长为35微秒，则当μ等于0时，该终端设备的第二切换间隔对应的时长可以为2个OFDM符号对应的时长。
前文提到，如果终端设备在频带组合内切换，则采用第一切换间隔；如果终端设备在频带组合间切换，则采用第二切换间隔。因此，终端设备和网络设备对终端设备是继续使用当前频带组合，还是即将切换至其他频带组合，以及如果终端设备即将切换至其他频带组合，那么终端设备应当切换至哪个频带组合(后文将该终端设备即将切换至的频带组合称为目标频带组合)需要有一致的理解，否则容易出现通信错乱。
在一些实施例中，终端设备的目标频带组合可以基于第一信息确定。第一信息可以包括以下信息中的一种或多种：当前频带组合以及调度信息对应的频带；当前频带组合、调度信息对应的频带以及目标频带组合的映射关系；当前频带组合、当前频带组合中的频带的序号和/或频带保持时间以及调度信息对应的频带；以及网络设备发送的指示信息。
在一些实施例中，针对前文所述的多个频带组合中的每个频带组合，如果N个频带中的不属于每个频带组合的任意一个频带仅属于除每个频带组合之外的一个频带组合，基于当前频带组合及调度信息对应的频带，即可以确定目标频带组合。也就是说，多个频带组合中除当前频带组合之外，只有一个频带组合包含目标频带，基于目标频带，即可以确定目标频带组合。例如，多个频带组合包括组合1(band1和band2)、组合2(band1和band3)和组合3(band1和band4)，如果当前工作的频带组合为组合1，目标频带为band3，则目标频带组合为组合2。又如，多个频带组合包括组合1(band1和band2)和组合2(band3和band4)，如果当前工作的频带组合为组合1，目标频带为band2，则目标频带组合为组合1。确定目标频带组合之后，可以根据当前频带是否在目标频带组合内，确定采用第一切换间隔或第二切换间隔或无切换时间。如果当前频带在目标频带组合内，则仅需第一切换间隔或0；如果当前频带不在目标频带组合内，则需要第二切换间隔。这种方法实现简单，且能尽可能地减少了平均的切换时延。
在一些实施例中，调度信息对应的频带还可以包括目标频带以及目标频带组合，即第一信息包括当前频带组合、调度信息对应的频带以及目标频带组合的映射关系。终端设备可以根据当前频带组合以及调度信息查询该映射关系，从而确定目标频带组合。
在一些实施例中，当前频带组合、调度信息对应的频带以及目标频带组合的映射关系可以由映射规则确定。例如，调度信息对应的频带为第一频带，一个或多个频带组合中的包含第一频带的频带组合包括第一频带组合和第二频带组合，第一频带组合仅包括第一频带，第二频带组合包括多个频带；如果当前频带组合包括多个频带，则目标频带组合为第一频带组合；如果当前频带组合仅包括一个频带，则目标频带组合为第二频带组合。
在一些实施例中，当前频带组合的信息还可以包括当前频带组合中频带的序号和/或频带保持时间，即第一信息包括当前频带组合、当前频带组合中的频带的序号和/或频带保持时间以及调度信息对应的频带。作为一种实现方式，根据与上述信息关联的确定规则可以确定终端设备目标频带组合。例如，确定规则可以包括目标频带替换当前频带组合中保持时间最长的频带，形成的频带组合即为目标频带组合。又如，确定规则可以包括目标频带替换当前频带组合序号最大或者最小的频带，形成的频带组合即为目标频带组合。
为了简化目标频带组合的确定方式，可以通过频带组合的指示信息直接确定目标频带组合。目标频带组合的指示信息可以由网络设备发送给终端设备。指示信息可以通过下行控制信令(downlink control information，DCI)、媒体接入控制单元(media access control control element，MAC CE)或无线资源控制(radio resource control，RRC)进行指示。
需要说明的是，在切换间隔内，终端设备不期待发送数据。
为了更加清晰完整的说明本申请提供的通信方法，后文结合示例1至示例5对本申请提供的多种 实施例进行详细介绍。
示例1：包含目标频带的频带组合仅有一个
在示例1中，本申请提供的通信方法包括步骤1至步骤4。
在步骤1，网络设备给终端配置了4个band，分别为band1、band2、band3和band4，如图3所示。
在步骤2，确定步骤1中的4个band对应的band组合，其中一个band组合可以包含一个或者多个band。进一步地，一个band组合最多包含2个band。
网络设备或终端设备可以将初始band组合进行上报：或者网络设备配置建议的band组合给终端设备，或者终端设备上报建议的band组合。如果由网络设备配置band组合，该配置过程可以和步骤1合并进行，也可以独立进行。
作为一种实现方式，band组合可以由终端设备上报，而终端设备可以根据实现的复杂度来决定频带组合。例如，相互之间容易切换的band可以属于一个band组合，相互之间切换复杂的band可以属于不同的band组合。
作为另一种实现方式，band组合可以由网络设备配置给终端，网络设备可以根据调度需求来确定目标频带组合。例如，经常调用或组合调用band属于一个band组合，不常组合的band属于不同的band组合里。
作为一个示例，上述4个band可以分为3个band组合，其中第一band组合包含band1和band2，第二band组合包含band1和band3，第三band组合包含band1和band4。可以看出，band1包含在所有band组合，且所有band组合的每个band组合中除第一band以外，其他band完全不同。
在步骤3，确定当前band组合。例如，终端当前工作在band组合1。
在步骤4，终端设备接收调度信息，该调度信息调度的数据承载在第一band(即目标频带)上。根据第一band是否在当前组合内，确定采用第一切换间隔或第二切换间隔或切换间隔为0。
如果第一band在当前组合内，则仅需第一切换间隔或无切换时间。对于这种情况，终端设备可以根据当前协议约定，即TS38.2146.1.6.2和6.1.6.3确定采用第一切换间隔还是无切换时间(即切换间隔为0)。当第一band不在当前组合内，则需要第二切换间隔，第二切换间隔例如可以采用前文所述的方法进行确定。
重新参见图3，图中通过虚线箭头和实线箭头分别示出了频带组合内切换和频带组合间切换的多种情况。作为一个示例，当终端设备被调度在band1上传输数据，由于band1在band组合1内，且根据当前协议约定，无需切换时间。作为另一个示例，当终端设备被调度在band2上传输数据，由于band2在band组合1内，且根据当前协议约定，采用第一切换间隔。作为又一个示例，当终端被调度在band3上传输数据，由于band3不在band组合1内，且根据当前协议约定，采用第二切换间隔。通常，band组合也一并切换到band组合2(目标频带组合)。
为了实现调度数据的可靠传输，调度信息和调度数据之间的间隔至少大于等于0或第一切换间隔或第二切换间隔。
另外，在切换间隔内，终端不在任何载波上传输数据。
这种情况下，从当前频带切换到目标频带以及目标频带组合实现简单，而且可以尽量减少平均的切换时延。
示例1给出了频带组合中仅包含一个目标频带组合(即无模糊问题)的目标频带以及目标频带组合的确定方法，示例2至示例5分别给出了频带组合中包含目标频带的频带组合不止一个(即有模糊问题)的解决方案。
示例2：有模糊问题的解决方案1
在示例2中，本申请提供的通信方法包括步骤1至步骤4。
在步骤1，网络设备给终端配置了3个band，分别为band1、band2和band3，如图4所示。
在步骤2，确定步骤1中的3个band对应的band组合，其中一个band组合可以包含一个或者多个band。进一步地，一个band组合最多包含2个band。
网络设备或终端设备可以将初始band组合进行上报：或者网络设备配置建议的band组合给终端设备，或者终端设备上报建议的band组合。如果由网络设备配置band组合，该配置过程可以和步骤1合并进行，也可以独立进行。
作为一种实现方式，band组合可以由终端设备上报，而终端设备可以根据实现的复杂度来决定频带组合。例如，相互之间容易切换的band可以属于一个band组合，相互之间切换复杂的band可以属于不同的band组合。
作为另一种实现方式，band组合可以由网络设备配置给终端，网络设备可以根据调度需求来确定目标频带组合。例如，经常调用或组合调用band属于一个band组合，不常组合的band属于不同的band 组合里。
作为一个示例，上述3个band可以分为3个band组合，其中第一band组合包含band1和band2，第二band组合包含band2和band3，第三band组合包含band1和band3。
在步骤3，确定当前band组合。例如，终端当前工作在band组合1。
在步骤4，终端设备接收调度信息，该调度信息调度的数据承载在第一band(即目标频带)上。根据第一band是否在当前组合内，确定采用第一切换间隔或第二切换间隔或切换间隔为0。
如果第一band在当前组合内，则仅需第一切换间隔或无切换时间。对于这种情况，终端设备可以根据当前协议约定，即TS38.2146.1.6.2和6.1.6.3确定采用第一切换间隔还是无切换时间(即切换间隔为0)。当第一band不在当前组合内，则需要第二切换间隔，第二切换间隔例如可以采用前文所述的方法进行确定。
如果终端设备被调度在band1上传输数据，由于band1在band组合1内，根据当前协议约定，无需切换时间。如果终端设备被调度在band2上传输数据，由于band2在band组合1内，根据当前协议约定，采用第一切换间隔。如果终端被调度在band3上传输数据，由于band3不在band组合1内，根据当前协议约定，采用第二切换间隔。
通常进行band切换时，band组合也可以一并切换到对应的band组合上。由于频带组合中包含目标频带的频带组合不止一个，可以根据当前频带组合、调度信息对应的频带(目标频带)以及目标频带组合的映射关系确定目标频带组合。当前频带组合、目标频带与目标频带组合的映射关系可以由网络设备进行配置。
重新参见图4，图中通过虚线箭头和实线箭头分别示出了该方案中频带组合内切换和频带组合间切换的多种情况。作为一个示例，网络设备配置的映射关系包括{当前band组合1，调度band3}对应目标频带组合为band组合2，则终端被调度在band3上传输数据时，终端切换到band组合2。
为了实现调度数据的可靠传输，调度信息和调度数据之间的间隔至少大于等于0或第一切换间隔或第二切换间隔。
另外，在切换间隔内，终端不在任何载波上传输数据。
示例3：有模糊问题的解决方案2

在步骤2，确定步骤1中的3个band对应的band组合，其中一个band组合可以包含一个或者多个band。进一步地，一个band组合最多包含2个band。
网络设备或终端设备可以将初始band组合进行上报：或者网络设备配置建议的band组合给终端设备，或者终端设备上报建议的band组合。如果由网络设备配置band组合，该配置过程可以和步骤1合并进行，也可以独立进行。
作为一种实现方式，band组合可以由终端设备上报，而终端设备可以根据实现的复杂度来决定频带组合。例如，相互之间容易切换的band可以属于一个band组合，相互之间切换复杂的band可以属于不同的band组合。
作为另一种实现方式，band组合可以由网络设备配置给终端，网络设备可以根据调度需求来确定目标频带组合。例如，经常调用或组合调用band属于一个band组合，不常组合的band属于不同的band组合里。
作为一个示例，上述3个band可以分为6个band组合，其中第一band组合包含band1和band2，第二band组合包含band2和band3，第三band组合包含band1和band3，第四band组合包含band1，第五band组合包含band2，第六band组合包含band3。
在步骤3，确定当前band组合。例如，终端当前工作在band组合1。
在步骤4，终端设备接收调度信息，该调度信息调度的数据承载在第一band(即目标频带)上。根据第一band是否在当前组合内，确定采用第一切换间隔或第二切换间隔或切换间隔为0。
如果第一band在当前组合内，则仅需第一切换间隔或无切换时间。对于这种情况，终端设备可以根据当前协议约定，即TS38.2146.1.6.2和6.1.6.3确定采用第一切换间隔还是无切换时间(即切换间隔为0)。当第一band不在当前组合内，则需要第二切换间隔，第二切换间隔例如可以采用前文所述的方法进行确定。
如果终端设备被调度在band1上传输数据，由于band1在band组合1内，根据当前协议约定，无需切换时间。如果终端设备被调度在band2上传输数据，由于band2在band组合1内，根据当前协议约定，采用第一切换间隔。如果终端被调度在band3上传输数据，由于band3不在band组合1内，根据当前协议约定，采用第二切换间隔。
通常进行band切换时，band组合也可以一并切换到对应的band组合上。由于频带组合中包含目标频带的频带组合不止一个，可以根据当前频带组合、调度信息对应的频带以及目标频带组合的映射规则确定目标频带组合。
如果调度band在当前band组合之外，且当前Band组合包含2个band，则可以切换到一个band组合，且该band组合仅包含调度band。如果调度band在当前band组合之外，且当前band组合仅包含1个band，则切换到一个band组合，且该band组合包含2个band。重新参见图5，图中通过虚线箭头和实线箭头分别示出了该方案中频带组合内切换和频带组合间切换的多种情况。
为了实现调度数据的可靠传输，调度信息和调度数据之间的间隔至少大于等于0或第一切换间隔或第二切换间隔。
另外，在切换间隔内，终端不在任何载波上传输数据。

如果调度band在当前band组合之外，且当前band组合包含2个band，则切换到一个band组合，则调度band替换当前band组合中的保持时间最长和/或序号最小/大的band，形成新的band组合。例如，当前band组合为band组合1，如果band3被调度，则根据序号最小原则(即使用调度band替换掉当前band组合中序号最小的band)，可以切换到band组合2；如果band1被调度，则根据保持时间最长原则，切换到band组合3。
为了实现调度数据的可靠传输，调度信息和调度数据之间的间隔至少大于等于0或第一切换间隔或第二切换间隔。
另外，在切换间隔内，终端不在任何载波上传输数据。

根据第一band是否在当前组合内，确定采用第一切换间隔或第二切换间隔或切换间隔为0。如果第一band在当前组合内，则仅需第一切换间隔或无切换时间。对于这种情况，终端设备可以根据当前协议约定，即TS38.2146.1.6.2和6.1.6.3确定采用第一切换间隔还是无切换时间(即切换间隔为0)。当第一band不在当前组合内，则需要第二切换间隔，第二切换间隔例如可以采用前文所述的方法进行确定。

为了实现调度数据的可靠传输，调度信息和调度数据之间的间隔至少大于等于0或第一切换间隔或第二切换间隔。
另外，在切换间隔内，终端不在任何载波上传输数据。
