Description

通信方法和装置
本申请要求于2022年3月31日提交中国专利局、申请号为202210346423.3、申请名称为“通信方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种通信方法和装置。
背景技术
目前，终端设备在各个状态之间进行切换时，可能会出现如下场景：例如，终端设备在时隙#1上发送射频链的状态为状态#1(例如，状态#1为通道#1上使用频段#A，通道#2上使用频段#2)，在时隙#2上可能会接收到两个下行控制信息(downlink control information，DCI)，指示终端设备切换到状态#2上时使用的频段(例如，DCI#1指示使用频段#A，DCI#2指示使用频段#C)。
由于终端设备不可能同时处理两个下行控制信息，例如，终端设备可能会先处理第一个下行控制信息，然后再处理第二控制信息。此时，终端设备可能会参照切换前的状态#1默认对应下行控制信息指示的频段。例如，终端设备在通道#1上仍然使用频段#A，在通道#2上使用频段#C，并且开始进行配置通道参数。然而，终端设备的通道#2可能不支持使用频段#C，此时，终端设备需要撤销之前配置的通道参数，并且重新配置通道参数，由此增加了终端设备的处理时延。因此，如何避免上述通道对应的频段重配置，减小终端设备的处理时延，成为亟待解决的问题。

本申请实施例中所涉及到的终端设备可以包括各种具有无线通信功能的接入终端、移动设备、用户终端或用户装置。例如，终端设备可以为用户设备(user equipment，UE)，例如，手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备等。终端设备也可是工业控制(industrial control)中的无线终端、机器类型通信(machine type communication，MTC)终端、客户终端设备(customer premise equipment，CPE)、无人驾驶(self-driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。
本申请实施例中所涉及到网络设备(例如，无线接入网设备)可以是终端设备通过无线方式接入到该移动通信系统中的接入设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，eNB)、家庭基站、无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)、宏基站或微基站、高频基站等。该无线接入网设备还可以为NR系统中的下一代基站(next generation node B，gNB)，或者，还可以是构成基站的组件或一部分设备，如汇聚单元(central unit，CU)、分布式单元(distributed unit，DU)或基带单元(baseband unit，BBU)等。应理解，本申请的实施例中，对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中，无线接入网设备简称网络设备，如果无特殊说明，在本申请中，网络设备均指无线接入网设备。在本申请中，网络设备可以是指网络设备本身，也可以是应用于网络设备中完成无线通信处理功能的芯片。
应理解，图1示出的场景仅仅是本申请技术方案使用的一种场景示例，本申请并不排除在其它场景中也需要终端设备在多个频带之间进行切换，也就是说，本申请的技术方案可以应用于各种终端设备需要在多个频带之间进行切换的场景。
5G新空口(new radio，NR)系统中，网络设备(例如，基站)发射功率很大可以将无线电波传送到很远的距离。但是，终端设备发射功率很小，上行覆盖受限，因此上行传输的信号在到达网络设备时的接收信号强度可能不足以保证其覆盖性能。此外，还会出现上行频谱不够的问题，因此不可能依赖对数据的重传来保证其上行覆盖性能。
图1是本申请技术方案适用的一种场景示意图，如图1所示，目前NR引入增补上行(supplementary uplink，SUL)作为NR系统中上行覆盖不足时的备选。由于长期演进(long term evolution，LTE)的低频带通常具有更好的覆盖性能，SUL考虑的是从LTE所在较低频带(例如，700MHz、1.8GHz或2.1GHz)中使用载波用于NR上行链路的传输。目前已经确定终端设备在使用LTE频带进行NR传输时可与LTE上行链路时分双工(time  division duplex，TDD)复用该频带。也就是说，当终端设备处于TDD中频带(2.6GHz、3.5GHz或4.9GHz)覆盖范围时，终端设备使用TDD中频带；当终端设备移动到TDD中频带(2.6GHz、3.5GHz或4.9GHz)覆盖范围之外时，终端设备在上行链路中可以采用LTE的低频带，这就增补了TDD中频带的上行覆盖短板，延伸了上行覆盖范围。当然，随着未来演进，终端设备在上行链路中也可以采用别的频带用作增补上行，进一步延伸上行覆盖范围。
也可以理解为，当终端设备在NR频带(band)(例如，2.6GHz)上传输上行数据时，可以从LTE所在较低频带(例如，700MHz/800MHz/900MHz、1.8GHz或2.1GHz)中使用载波用于NR上行传输，该载波可以理解为SUL频带。也就是说，在SUL的场景中，期望终端设备根据信道状态或者根据对应频带的负载状况，可以在700M/800M/900M、1.8G、2.1G、3.5G或4.9GHz等的多个频带之间进行动态切换。
为了便于理解本申请的技术方案，下面对本申请涉及到的几个专业术语进行简单的说明。
锁相环(phase locked loop，PLL)的切换时延：通常来说，锁相环重新锁定在一个频带上需要约300微秒。具体来说，一个频带的锁相环关了，重新锁到其他的频带上，或者开启一个新的锁相环，都需要这样的切换时延。
发射通道(transmitter，TX)：可以称为“射频(radio frequency，RF)发射通道”，也可以简称为“发射通道”。在本申请中，发射通道可以是按照如下方式工作的，但不仅限于如下方式：发射通道可接收来自基带芯片的基带信号，对基带信号进行射频处理(如上变频、放大和滤波)以得到射频信号，并最终通过天线将该射频信号辐射到空间中。例如，发射通道可以包括天线开关、天线调谐器、低噪声放大器(low noise amplifier，LNA)、功率放大器(power amplifier，PA)、混频器(mixer)、本地振荡器(local oscillator，LO)和滤波器(filter)等电子器件，这些电子器件可以根据需要集成到一个或多个芯片中。天线有时也可以认为是发射通道的一部分。
本申请的下述实施例中提及的“通道”也可以理解为“射频链”。本申请中射频链也可以替换为TX、天线、射频、发射通道、发送端口、接收通道或者它们的任意组合，以下不再赘述。
应理解，本申请实施例中提到的“频段”(band)也可以理解为，“频带”、“频点”“频谱”。也可以将本申请中的“频带”理解为分量载波(component carrier，CC)(也可以简称为“载波”)，即本申请的技术方案对“载波”也是完全适用的。本申请的下述实施例中主要是以“频段”为例进行描述的。
本申请中，发送射频链也可以理解为“发送”、“能发送”、“传输”或者“能传输”。相应的，发送射频链的数量可以理解为“发送的数量”、“能发送的数量”、“传输的数量”或者“能传输的数量”。发送射频链的数量还可以理解为“层数”、“天线层数”或“通道数”。
本申请实施例中提到的“切换”(switch)也可以理解为“转换”；本申请实施例提到的“切换时延”，也可以理解为“载波切换时延”、“载波转换时延”、“载波转换周期(period或interval)”或“转换间隔(gap)”；本申请实施例提到的“切换时延”，还可以称之为“载波切换准备时间中的切换时间(switching time)”或者“切换准备提前 量中的切换时间(switching time)”。对应的，网络设备在进行上行调度时，会根据切换时延，进行相应的调度处理，具体可以理解为设置N2(N2可以理解为，上行处理时延或上行准备时延)，以下不再赘述。
终端设备的各个通道支持的频段不完全相同，例如通道#1可能支持频段#A、频段#C，通道#2可能支持频段#A、频段#B。终端设备在各个状态之间进行切换时，可能会出现如下场景：例如，终端设备在时隙#1上发送射频链的状态为状态#1(例如，状态#1为通道#1上使用频段#A，通道#2上使用频段#2)，在时隙#2上可能会接收到两个下行控制信息(downlink control information，DCI)，指示终端设备切换到状态#2上时使用的频段。例如，DCI#1指示使用频段#A，DCI#2指示使用频段#C。由于终端设备不可能同时处理两个下行控制信息，例如，终端设备可能会先处理第一个下行控制信息，然后再处理第二控制信息。此时，终端设备可能会参照切换前的状态#1默认对应下行控制信息指示的频段。例如，终端设备在通道#1上仍然使用频段#A，在通道#2上使用频段#C，并且开始进行配置通道参数。然而，终端设备的通道#2可能不支持使用频段#C，此时，终端设备需要撤销之前配置的通道参数，并且重新配置通道参数，由此增加了终端设备的处理时延。应理解上述场景仅仅是本申请的一个示例，终端设备在各个状态之间进行切换时，此类的场景还有很多，此处不再一一举例分析。
有鉴于此，本申请提供一种通信方法，通过网络设备向终端设备指示切换前的频段和/或载波、切换后的频段和/或载波，使得终端设备可以明确获知打断哪个频段/载波并且切换到目标频带/载波，避免了终端设备的通道对应的频段重配置的问题，减少了终端设备的处理时延，提高数据传输性能。
需要说明的是，本申请中提及到的“关联”、“对应”、“隐性对应”之间可以互相替换。本申请中提到的“根据”均可以理解为“基于”。
本申请提到的“对应关系”、“关联关系”等都可以是网络设备通过无线资源控制(radio resource control，RRC)信令向终端设备配置的，或者可以理解为是预定的规则。
图2是是本申请提供的通信方法200，方法200从终端设备与网络设备交互的角度示例了本申请技术方案的具体实施例步骤，下面对图2所示的各步骤进行说明。
步骤201，终端设备向网络设备发送第六信息。
在一种可能的实现方式中，第六信息可以包括终端设备的各个通道与频段的对应关系，该频段为各个通道支持的频段。例如，每个通道支持在两个频段上传输；又例如，每个通道支持在三个频段上传输，等等，本申请对通道的个数不予限定，对每个通道支持的频段数量也不予限定。
作为一个示例，终端设备可以上报通道#1支持频段#A、频段#C，通道#2支持频段#A、频段#B。又例如，终端设备可以上报通道#1支持频段#A、频段#D，通道#2支持频段#A、频段#B，通道#3支持频段#B、频段#C，通道#4支持频段#A、频段#C，等等。
本申请中，各个通道支持的频段，可以理解为各个通道支持在该频段上的数据传输。
在另一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，频段之间的切换对应关系。例如，第一状态为终端设备在第一频段组上的频段支持第一数量的发送射频链，第二状态为终端设备在第二频段组上的频段支持第二数量的发送射频链。
本申请中，该“第一频段组上的频段”也可以理解为至少一个第一频段，该“第二频段组上的频段”也可以理解为至少一个第二频段。此时，第一状态可以理解为，终端设备在至少一个第一频段上支持第一数量的发送射频链，第二状态可以理解为，终端设备在至少一个第二频段上支持第二数量的发送射频链。
假设终端设备的通道#1支持频段#A、频段#C，通道#2支持频段#A、频段#B。作为一个示例，假设状态#4(第一状态的示例)为终端设备在通道#1上使用频段#A(第一频段的示例)发送一个射频链(“射频链”也可记为“TX”)，在通道#2上使用频段#B(第二频段的一个示例)发送一个射频链，状态#5(第二状态的示例)为终端设备在通道#1上使用频段#C(第一频段的另一个示例)发送一个射频链，在通道#2上使用频段#A(第二频段的另一个示例)发送一个射频链。则终端设备可以向网络设备上报通道#1上从频段#A切换到频段#C，通道#2上从频段#B切换到频段#A。例如，表格1所示。

作为另一个示例，假设状态#1(第一状态的示例)为终端在通道#2上使用频段#B(例如，通道#2上有两个发送射频链)，状态#4(第二状态的示例)为终端设备在通道#1上使用频段#A发送一个射频链，在通道#2上使用频段#B发送一个射频链。则终端设备可以向网络设备上报通道#2上从频段#B切换到频段#B(此时，也可以理解为，不用切换)，通道#1上使用的频段切换到频段#A(可以理解为，在切换前通道#1上还没有发送射频链)。例如，表格2所示。
表格2
在又一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，对应的切换时延。
作为一个示例，例如，终端设备可以上状态#4和状态#5之间进行切换需要的切换时延#1。切换时延#1可以是38微秒、140微秒、210微秒、280微秒、500微秒或者1毫秒，等等。又例如，终端设备可以上报状态#1和状态#5之间进行切换需要的切换时延#2。切换时延#2可以是38微秒、140微秒、280微秒、210微秒、280微秒、500微秒或者1毫秒，等等。当终端设备上报状态#1和状态#5之间进行切换需要的切换时延#2时，也可以理解为，隐含地指示了状态#1和状态#5之间的对应切换关系，即状态#1和状态#5之间能进行对应的切换。
在另一种可能的实现方式中，第六信息可以包括终端设备从至少一个第一频段切换到 至少一个第二频段时，频段之间的切换对应关系。
作为一个示例，终端设备可以上报从第一个第一频段切换到第一个第二频段，和/或，从第二个第一频段切换到第二个第二频段。参见表格1，例如，终端设备可以上报从频段#A切换到频段#C，从频段#B切换到频段#A。
在又一种可能的实现方式中，终端设备还可以上报从缺省状态或者回退状态切换到新的频带所需要的切换时延。此时，考虑到终端设备通过当前频段下完成传输后，还可以回退到缺省状态/回退状态所对应的频带下。例如，该切换时延可以为35微秒。回退到缺省状态/回退状态所对应的频带，表示锁相环锁定到缺省状态/回退状态所对应的频带。本申请中，缺省状态/回退状态可以是预定义的，或者网络设备预先配置的。本申请中，预先配置可以理解为网络设备通过无线资源控制(radio resource control，RRC)信令配置。
在另一种可能的实现方式中，终端设备还可以上报保留原来的状态。即，不会从网络设备调度传输的状态转到回退状态，只会在基站指示的状态上继续驻留。
步骤202，网络设备接收终端设备发送的第六信息，并确定第一信息。
例如，终端设备可以根据终端设备上报的第六信息，确定终端设备切换前的频段和/或载波、切换后的频段和/或载波。例如，表格1所示，终端设备可以向网络设备上报通道#1上从频段#A切换到频段#C，通道#2上从频段#B切换到频段#A。如果当前状态为频段#A 1Tx，和频段#B 1Tx，下一状态期望为频段#A 1Tx，和频段#C 1Tx，则网络设备可以确定终端设备应从频段#B打断当前传输，转向频段#A进行目标传输；还可以确定终端设备应从频段#A打断当前传输，转向频段#C进行目标传输。因此，切换前的频段为频段#B，切换后的频段为频段#A；以及切换前的频段为频段#A，切换后的频段为频段#C。
又例如，缺省状态为频段#A。如果当前状态与下一状态之间的时间间隔大于等于一个时间长度，终端设备进入缺省状态。可选的，该时间长度可以为预定义的，例如，为两个时隙(slot)的时长或者一个slot的时长。当下一状态期望为频段#A 1Tx，和频段#C 1Tx，则可以确定终端设备应从频段#A保留1Tx进行目标1Tx传输，并打断1Tx转向频段#C进行目标1Tx传输。
第一信息中包括至少一个信息块(block)(例如，N个信息块，N为大于0的整数)，其中，每个信息块可以关联终端设备切换前的频段和/或载波。也可以理解为，每个信息块可以隐性关联终端设备切换前的频段和/或载波。第一个信息块可以对应最低的频段索引和/或载波索引，依次，第N个信息块可以对应最高的频带索引和/或载波索引。又例如，第一个信息块可以对应最高的频段索引和/或载波索引，依次，第N个信息块可以对应最低的频段索引和/或载波索引。
本申请中，最低的频段索引和/或载波索引，最高的频段索引和/或载波索引，可以是针对终端设备当前所使用的频段和/或载波而言。例如，终端设备当前所使用的频段为n28和n43，则最低的频段索引为频段n28所对应的频段索引，最高的频段索引为频段n43所对应的频段索引。又例如，终端设备当前所使用的载波为服务小区(serving cell)#3和serving cell#5，则最低的载波索引为载波serving cell#3所对应的索引3，最高的载波索引为载波serving cell#5所对应的索引5。
示例性的，假设终端设备当前使用的频段为频段#1、频段#3，则第一个信息块可以对应终端频段#1，第二个信息块可以对应频段#3。假设，终端设备当前使用的频段为频段#28、 频段#36，例如，第一个信息块可以对应频段#28，第二个信息块可以对应频段#36，等等。
示例性的，假设终端设备当前使用的频段#1上的载波#3、频段#2上的载波#1，则第一个信息块可以默认对应频段#1上的载波#3，第二个信息块可以默认对应频段#2上的载波#1，等等。
示例性的，在一种实现方式中，可以对各个频段上的载波整体编一个索引。假设，每个频段上均可以支持四个载波，则频段#1～频段#3上的载波可以有12个，假设载波#1～载波4为频段#1上的载波，载波#5～载波#8为频段#2上的载波，载波#9～载波#12为频段#4上的载波。此时，第一个信息块可以对应载波#1，第二个信息块可以对应载波#2，第三个信息块可以对应载波#3，第十个信息块可以对应载波#10，等等。也可以理解为，此时通过信息块和载波的对应关系，也可以隐性指示切换后的频段。
示例性的，每个信息块还可以对应一个载波集合。其中，载波集合可以理解为将32个载波分成P(P为大于0的整数)个集合或者组，每个信息块对应一个载波集合的索引(index)或者载波组的索引。
具体的，本领域技术人员可以根据实际情况设计每个信息块关联频段和/或载波，不申请不予限定。
第一信息可以包括至少一个信息块，其中，每个信息块包括字段#1(第一字段的示例)，其中，字段#1用于指示切换后的频段和/或载波。
在一种实现方式中，字段#1中包括1比特第一指示，该1比特的第一指示用于指示是否从当前的频段和/或载波触发切换(indication on whether switch this band/CC)。字段#1中还可以包括第二指示(第二指示，例如可以占用3比特)，第二指示用于指示切换后的频段和/或载波(switch to band/CC)。例如，第二指示可以指示切换后频段的频段索引(switch to band index/CC index)。例如，第二指示可以指示切换后的频段为频段#3。又例如，第二指示可以指示切换后的频段的载波(例如，为频段#4的载波#1)。再例如，第二指示可以指示切换后的载波，例如，切换后的载波为载波#11(如前所述，此时可以隐式指示切换后的频段为频段#3)。
可选的，每个信息块还可以包括字段#2(第二字段的示例)，用于指示第一信息与其调度的上行数据之间的时间偏移量。也可以理解为，字段#2可以用于指示K2’或K1’。例如，网络设备可以根据终端设备上报的各个状态之间的切换时延，为终端设备确定上行数据的调度(例如，确定K2’)，使得终端设备在完成状态切换之后，按照字段#2的指示在特定的时隙或者符号上接收数据。可以避免终端设备还没有完成状态之间的切换就接收数据，提高了数据传输性能。
本申请中，该“时间偏移量”还可以是“时隙偏移量”或者“符号偏移量”，也可以是“时隙偏移量”和“符号偏移量”。
其中，K2为调度上行数据传输的时延(也可以称为：数据处理时间或数据准备时间)，K1为从调度物理下行共享信道(physical downlink shared channel，PDSCH)到反馈物理上行控制信道(physical uplink control channel，PUCCH)之间的时延。具体的，有关K2的说明可以参照第三代移动通信伙伴项目(the 3rd generation partner project，3GPP)中技术规范(technical specification，TS)38.214进行理解，有关K1的说明可以参照3GPP中的技术规范TS38.213，本申请中不再具体说明。
本申请中的，K2’例如可以是在现有K2的基础上加上锁相环锁定时间。同样的，K1’例如可以是在现有K1的基础上加上锁相环锁定时间。例如，K2’大于或等于三个时隙的时间或四个时隙的时间。
作为一个示例，可以为K2’单独定义一张表格(例如，现有协议中K2的表格记为“第一表格”，本申请中K2’的表格可以记为“第二表格”)。其中K2’不同于现有的K2表格中所列举的值。网络设备给终端设备指示K2’时，需要表格索引指示以及K2’的值指示。也可以理解为，此时需要指示第二表格。作为另一个示例，可以在目前K2表格的基础上再额外增加K2’的值。例如可以扩展比特位，此时不需要表格索引指示。
可选的，每个信息块还包含调制编码策略偏移(MCS offset)、传输功率控制(transmit power control，TPC)等调度信息中的至少一项，指示终端设备的在切换后的频段/载波上的传输速率。例如，网络设备可以参考当前的频段/载波的MCS信息、TPC信息，指示切换后的目标频段/载波的MCS信息、TPC信息等。
可选的，该第一信息上可以不包含任何调度信息(如MCS offset以及TPC)，这种情形下需要同时结合目标频段/载波的调度DCI。即，第一信息需要与调度在目标频段/载波上传输上行数据的DCI联合使用才可以完成目标频段/载波的上行数据传输。也可以理解为，此时第一信息只用来指示该切换是打断哪个频段/载波传输以及切换后的频段/载波，不用于进行调度指示。
如图3所示，每个信息块可以对应当前锁相环所锁定或驻留的频段和/或载波。例如，可以与频段和/或载波的编号(“编号”也可以理解为“索引”)从低到高依次对应，或者，可以与频段/载波的编号从高到低依次对应(其中，图3中虚线示出的字段表示可选的)。
例如，上述第一信息可以是组公共下行控制信息(group common DCI)(即，此时一个或者多个终端都可以基于该DCI确定切换后的频段/载波)，并且该DCI的冗余校验码(cyclic redundancy check，CRC)通过新的物理上行共享信道切换无线网络临时标识(PUSCH-switch-RNTI)加绕。新的物理上行共享信道切换无线网络临时标识为网路设备通过RRC信令配置的。此时，第一信息中不用指示第二表格，这是由于采用新的RNTI加扰，终端设备可以通过解该RNTI便可以默认确定其中所含的时延为第二表格中的时延。
步骤203，网络设备向终端设备发送第一信息。
例如，网络设备可以向终端设备发送group common DCI。
步骤204，终端设备接收网络设备发送的第一信息，并根据第一信息在切换后的频段/载波上传输上行数据。
作为一个示例，假设终端设备当前在通道#1中使用频段#18，在通道#2中使用频段#20传输上行数据，终端设备接收到的第一信息中包括两个信息块，第一个信息块对应频段#18，第二个信息块对应频段#20。第一个信息块中包括字段#1，字段#1中的第一指示，指示从当前频段进行切换(即，“indication on whether switch this band”为“1”)，字段#1中的第二指示，指示切换后的频段为频段#16。类似的，第二个信息块中也包括字段#1，字段#1中的第一指示，指示从当前频段进行切换，字段#1中的第二指示，指示切换后的频段为频段#18。即，终端设备可以从频段#18和频段#20(例如，第四状态)，切换到频段#16和频段#18(例如，第五状态)。
作为另一个示例，假设终端设备当前在通道#1中使用载波#12(例如，隐性对应频段#3)，在通道#2中使用载波#25(例如，隐性对应频段#7)传输上行数据。终端设备接收到的第一信息中包括两个信息块，第一个信息块对应载波#12，第二个信息块对应载波#25。第一个信息块中包括字段#1，字段#1中的第一指示，指示从当前载波进行切换(即，“indication on whether switch CC”为“1”)，字段#1中的第二指示，指示切换后的载波为频段#13(例如，隐性对应频段#4)。类似的，第二个信息块中也包括字段#1，字段#1中的第一指示，指示从当前载波进行切换，字段#1中的第二指示，指示切换后的载波为载波#10(例如，隐性对应频段#3)。即，终端设备可以从载波#12和载波#25(例如，第四状态)，切换到载波#13和载波#10(例如，第五状态)。
本申请中，终端设备可以通过第一信息，确定需要打断哪个频段和/或载波并且明确切换后的频段和/或载波，避免了终端设备的通道对应的频段重配置的问题，减少了时延。
可选的，如果第一信息中还包括字段#2，例如，终端设备当前在时隙#1上接收第一信息，字段#2可以指示终端设备在第二时隙的第三符号上发送数据，即，可以从时隙#2的第三符号开始使用频段#16、频段#18发送数据。
本申请中，终端设备通过第一信息可以确定在哪个时隙或者哪些符号上使用切换后的频段/载波发送上行数据，使得终端设备在完成状态切换之后，按照字段#2的指示在特定的时隙上接收数据。可以避免终端设备还没有完成状态之间的切换就接收数据，提高了数据传输性能。
本申请还提供的另一通信方法300，方法300从终端设备与网络设备交互的角度示例了本申请技术方案的具体实施例步骤，方法300的步骤与方法200的步骤类似，具体的流程示意图可以参照图2进行理解，不再重复示出，下面对方法300的步骤进行说明。
步骤301，终端设备向网络设备发送第六信息。
在一种可能的实现方式中，第六信息可以包括终端设备的各个通道与频段的对应关系，该频段为各个通道支持的频段。
在另一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，频段之间的切换对应关系。
在另一种可能的实现方式中，第六信息可以包括终端设备从至少一个第一频段切换到至少一个第二频段时，频段之间的切换对应关系。
在又一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，对应的切换时延。
在又一种可能的实现方式中，终端设备还可以上报从缺省状态或者回退状态切换到新的频带所需要的切换时延。
在另一种可能的实现方式中，终端设备还可以上报保留原来的状态。即，不会从网络设备调度传输的状态转到回退状态，只会在基站指示的状态上继续驻留。
具体的，可以参照方法200中的步骤201中的描述进行理解，此处不再赘述。
步骤302，网络设备接收终端设备发送的第六信息，并根据第六信息确定第二信息。
本实施例中，第二信息包括至少一个信息块(例如，M个信息块，M为大于0的整数。)，每个信息块与终端设备的频段对(band pair)相关联，其中，该频段对包括终端设备切换前的频段以及终端设备切换后的频段。该“频段对”可以理解为{切换前的频段 (switch from band)—切换后的频段(switch to band)}。也可以理解为，每个信息块隐性关联终端设备切换前的频段以及切换后的频段。
作为一个示例，第一个信息块可以对应频段对#1，第二个信息块可以对应频段对#2，第三个信息块可以对应频段对#3，等等。假设，终端设备支持在三个频段(例如，频段#A、频段#B、频段#C)上进行数据传输，则频段对可以有3×2＝6个。假设，终端设备支持在四个频段(例如，频段#A、频段#B、频段#C、频段#D)上进行数据传输，则频段对可以有4×3＝12个。例如，表格3示出了终端设备支持三个频段时，频段对的情况。也就是说，本实施例中每个信息块可以隐性的对应切换前的频段和切换后的频段，终端设备可以根据每个信息块获知需要打断哪个频段以及切换后的频段。表格3可以为网络设备通过RRC信令配置的，或者预定义的。
表格3
在一种实现方式中，每个信息块中包括1比特第三指示，该1比特的第三指示用于指示是否从当前的频段对触发切换(indication on whether switch this bandpair)。
可选的，每个信息块中还可以包括字段#3(第三字段的示例)，字段#3用于指示切换后的载波。例如，可以指示切换后的载波的索引(例如，switch to CC index)。
例如，第一个信息块对应频段对#1，字段#3还可以进一步指示切换后的载波为频段#B上的载波#1。又例如，第二个信息块对应频段对#2，第二信息块上的字段#3可以进一步指示切换后的载波为，频段#C上的载波#4，等等。
可选的，每个信息块中还包括字段#2(第二字段的示例)，用于指示第一信息与其调度的上行数据之间的时间偏移量。具体的，关于字段#2的理解可以参照方法200中的步骤202中的描述，此处不再赘述。
可选的，每个信息块还包含调制编码策略偏移(MCS offset)、传输功率控制(transmit power control，TPC)等调度信息中的至少一项，指示终端设备的在切换后的频段/载波上的传输速率。例如，网络设备可以参考当前的频段/载波的MCS信息、TPC信息，指示切换后的目标频段/载波的MCS信息、TPC信息等。
可选的，每个信息块上不包含任何调度信息(如MCS offset以及TPC)，这种情形下需要同时结合目标频段/载波的调度DCI。即，第二信息需要与调度在目标频段/载波上传输上行数据的DCI联合使用才可以完成目标频段/载波的上行数据传输。也可以理解为，此时第二信息只用来指示该切换是打断哪个频段/载波传输以及切换后的频段/载波，不用于进行调度指示。
如图4所示，每个信息块可以对应一个频段对。例如，可以与频段对的编号(“编号” 也可以理解为“索引”)从低到高依次对应，或者，可以与频段对的编号从高到低依次对应。
例如，上述第二信息可以是组公共下行控制信息(group common DCI)，并且该DCI的CRC可以通过新的物理上行共享信道切换无线网络临时标识(PUSCH-switch-RNTI)加绕。此时，第二信息中不用指示第二表格，这是由于采用新的RNTI加扰，终端设备可以通过解该RNTI便可以默认确定其中所含的时延为第二表格中的时延。
步骤303，网络设备向终端设备发送第二信息。
例如，网络设备可以向终端设备发送group common DCI。
步骤304，终端设备接收网络设备发送的第二信息，并根据第二信息在切换后的频段上传输上行数据。
作为一个示例，假设终端设备当前在通道#1中使用频段#18，在通道#2中使用频段#20。终端设备接收到第二信息，第二信息包括两个信息块，第一个信息块对应频段对#1，假设频段对#1指示切换前的频段为频段#18，切换后的频段为频段#16。例如，第一个信息块中1比特的第三指示(indication on whether switch this band pair)为1，则终端设备确定从频段#18切换到频段#16。同样的，第二个信息块对应频段对#2，频段对#2指示切换前的频段为频段#20，切换后的频段为频段#18。第二个信息块中1比特的第三指示(indication on whether switch this band pair)为1，则终端设备确定从频段#20切换到频段#18。即，终端设备可以从频段#18和频段#20(例如，第四状态)，切换到频段#16和频段#18(例如，第五状态)。
进一步的，如果第一个信息块中还包括字段#3，字段#3指示终端设备切换后的载波为载波#1。即，终端设备可以确定在切换后的频段#16上的载波#1上传输上行数据。又例如，第二个信息块中包括字段#3，字段#3指示终端设备切换后的载波为载波#3。即，终端设备可以确定在切换后的频段#18上的载波#3上传输上行数据。
本申请中，终端设备可以通过第二信息，确定需要打断哪个频段并且明确切换后的频段或载波，避免了终端设备的通道对应的频段重配置的问题，减少了时延。
可选的，如果第二信息中还包括字段#2，例如，终端设备当前在时隙#1上接收第一信息，字段#2可以指示终端设备在第二时隙的第三符号上发送数据，即，可以从时隙#2的第三符号开始使用频段#16、频段#18发送数据。
本申请中，终端设备通过第二信息可以确定在哪个时隙或者哪些符号上使用切换后的频段/载波发送上行数据，使得终端设备在完成状态切换之后，按照字段#2的指示在特定的时隙上接收数据。可以避免终端设备还没有完成状态之间的切换就接收数据，提高了数据传输性能。
本申请还提供的另一通信方法400，方法400从终端设备与网络设备交互的角度示例了本申请技术方案的具体实施例步骤，方法400的步骤与方法200的步骤类似，具体的流程示意图可以参照图2进行理解，不再重复示出，下面对方法400的步骤进行说明。
步骤401，终端设备向网络设备发送第六信息。
在一种可能的实现方式中，第六信息可以包括终端设备的各个通道与频段的对应关系，该频段为各个通道支持的频段。
在另一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与 第二状态)之间进行切换时，频段之间的切换对应关系。
在又一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，对应的切换时延。
在另一种可能的实现方式中，第六信息可以包括终端设备从至少一个第一频段切换到至少一个第二频段时，频段之间的切换对应关系。
在又一种可能的实现方式中，终端设备还可以上报从缺省状态或者回退状态切换到新的频带所需要的切换时延。
在另一种可能的实现方式中，终端设备还可以上报保留原来的状态。即，不会从网络设备调度传输的状态转到回退状态，只会在基站指示的状态上继续驻留。
具体的，可以参照方法200中的步骤201中的说明进行理解，此处不再赘述。
步骤402，网络设备接收终端设备发送的第六信息，并根据第六信息确定第三信息。
本实施例中，第三信息包括字段#1(第一字段的示例)，字段#1(例如，“switchfrom band/CC index”)用于指示终端设备切换后的频段和/或载波。例如，字段#1指示终端设备切换后的频段为频段#10。又例如，字段#1指示终端设备切换后的载波为载波#17(此时，根据载波可以隐性确定切换后的频段，具体的理解可以参见方法200中的步骤202的描述)。再例如，字段#1可以显性指示切换后的频段并且隐性关联切换后的载波。例如，字段#1指示终端设备切换后的频段为频段#10，并且默认关联切换后的载波为频段#10上的载波#4，等等。
在一种可能的实现方式中，第三信息还包括字段#8(“switchto band/CC”)用于指示切换后的频段和/或载波(例如，字段#8可以用于指示切换后的频段和/或载波(“switchto band/CC index”))。具体的实现方式可以参照上述字段#1指示终端设备切换前的频段的实现进行理解，此处不再赘述。
在另一种可能的实现方式中，切换前的频段和/或载波可以是终端设备基于预设的规则确定的。例如，预设的规则为：从终端设备所在频段和/或载波按相应索引中最低的开始进行打断传输；或者，从终端设备所在频段和/或载波按相应索引中最高的开始进行打断传输。又例如，预设的规则为：从终端设备所在频段和/或载波按相应索引进行升序排列，从其中最低的开始，依次选择进行打断传输；或者，从终端设备所在频段和/或载波按相应索引进行降序排列，从其中最高的开始，依次选择进行打断传输。
上述“switch from band”可以通过0/1指示目前驻留的频段中较低的/较高的，或者指示band index。例如，可以复用UL/SUL 1bit或填充位(padding bit)。上述，switch to band index/CC index也可以通过0/1指示配置的多个频段中除了目前驻留的频段，在剩余的频段中较低的/较高的，或者指示band index/CC index，也可以复用UL/SUL 1bit或填充位。
可选的，switch from band/CC与switch to band/CC的对应关系可以通过RRC信令进行配置，或者也可以是预定义的，可以参照上述表格3进行理解。此时，第三信息可以指示该配置中的切换对应关系索引的值。
在一种可能的实现方式中，例如，切换前的载波(例如，switch from CC index)不需要显性指示，可以通过切换前的频段(switch from band index)隐性获知。例如，可以预先规定从频段#1上的载波#2进行切换，或者，从频段#2上的载波#1进行切换等等。切换后的载波(switch to CC index)，例如，可以通过跨载波调度的载波指示域(carrier indicator  field,CIF)指示。
可选的，第三信息中还可以包括字段#2(第二字段的示例)用于指示第一信息与其调度的上行数据之间的时间偏移量。具体的，关于字段#2的理解可以参照方法200中的步骤202中的描述，此处不再赘述。进一步的，如果第三信息包括字段#2，此时，第三信息还可以包括字段#4，用于指示时间偏移量的位置。例如，字段#4可以用于指示所述时间偏移量所在的第二表格(即，可以为K2’重新设计一个第二表格)，或者，所述字段#4用于指示时间偏移量在第一表格中的索引或位置(此时，可以在现有的K2表格(记为“第一表格”)中扩充比特位来指示K2’)。
可选的，第三信息还包含调制编码策略偏移(MCS offset)、传输功率控制(transmit power control，TPC)等调度信息中的至少一项，指示终端设备的在切换后的频段/载波上的传输速率。例如，网络设备可以参考当前的频段/载波的MCS信息、TPC信息，指示切换后的目标频段/载波的MCS信息、TPC信息等。
可选的，第三信息不包含任何调度信息(如MCS offset以及TPC)，这种情形下需要同时结合目标频段/载波的调度DCI。即，第二信息需要与调度在目标频段/载波上传输上行数据的DCI联合使用才可以完成目标频段/载波的上行数据传输。也可以理解为，此时第二信息只用来指示该切换是打断哪个频段/载波传输以及切换后的频段/载波，不用于进行调度指示。图5示出了第三信息可能包含的字段。
例如，上述第三信息可以是动态调度的下行控制信息(例如，DCI 0_1)，并且可以通过现有的物理上行共享信道切换无线网络临时标识(PUSCH-switch-RNTI)加绕。此时，第三信息中需要指示第二表格，这是因为使用现有的RNTI加绕，终端设备通过该解扰方式无法确定其中所含的时延为第二表格中的时延，所以需要明确指示出第二表格。
本实施例中，第三信息也可以是包含多个信息块，每个信息块中包括字段#1(即，指示切换前的频段和/或载波)，并且每个信息块中还可以包括字段#8(即，指示切换后的频段和/或载波)，也可以理解为，本实施例中的信息块不会与切换前的频段和/或载波隐性关联，因此，切换前的频段和/或载波以及切换后的载波和/或索引均需要显性指示。可选的，每个信息块中还可以包括字段#2。可选的，每个信息块中还可以包括调制编码策略偏移(MCS offset)、传输功率控制(transmit power control，TPC)等调度信息中的至少一项。可选的，每个信息块中不包括任何调度信息。此时，第三信息可以是压缩下行控制信息(compact DCI)(DCI 0_0)，并且可以通过新的RNTI加扰。
步骤403，网络设备向终端设备发送第三信息。
例如，网络设备可以向终端设备发送动态调度的DCI，或者，网络设备向字段设备发送compact DCI。
步骤404，终端设备接收网络设备发送的第三信息，并根据第三信息在切换后的频段上传输上行数据。
作为一个示例，以第三信息指示频段为例(对于第三信息指示载波的情况也可以类似理解)。例如，网络设备可以同时下发两个第三信息，假设终端设备当前在通道#1中使用频段#18，在通道#2中使用频段#20。假设第一个第三信息指示切换前的频段为频段#18，切换后的频段为频段#16，第二个第三信息指示切换前的频段为频段#20，切换后的频段为频段#18。则终端设备根据第三信息的指示将通道#1中的频段切换为频段#16，将通道#2 中的频段切换为频段#18。即，终端设备可以从频段#18和频段#20(例如，第四状态)，切换到频段#16和频段#18(例如，第五状态)。
可选的，如果该DCI通过现有的RNTI加扰，则第三信息中还包括K2’的位置指示，例如，K2’所在的第二表格，终端设备可以根据该指示确定K2’。
本申请中，终端设备可以通过第三信息，确定需要打断哪个频段并且明确切换后的频段或载波，避免了终端设备的通道对应的频段重配置的问题，减少了时延。
可选的，如果第二信息中还包括字段#2，例如，终端设备当前在时隙#1上接收第一信息，字段#2可以指示终端设备在第二时隙的第三符号上发送数据，即，可以从时隙#2的第三符号开始使用频段#16、频段#18发送上行数据。
本申请中，终端设备通过第三信息可以确定在哪个时隙或者哪些符号上使用切换后的频段/载波发送上行数据，使得终端设备在完成状态切换之后，按照字段#2的指示在特定的时隙上接收数据。可以避免终端设备还没有完成状态之间的切换就接收数据，提高了数据传输性能。
本申请还提供的另一通信方法500，方法500从终端设备与网络设备交互的角度示例了本申请技术方案的具体实施例步骤，方法500的步骤与方法200的步骤类似，具体的流程示意图可以参照图2进行理解，不再重复示出，下面对方法500的步骤进行说明。
步骤501，终端设备向网络设备发送第六信息。
在一种可能的实现方式中，第六信息可以包括终端设备的各个通道与频段的对应关系，该频段为各个通道支持的频段。
在另一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，频段之间的切换对应关系。
在又一种可能的实现方式中，第六信息包括终端设备在各个状态(例如，第一状态与第二状态)之间进行切换时，对应的切换时延。
在另一种可能的实现方式中，第六信息可以包括终端设备从至少一个第一频段切换到至少一个第二频段时，频段之间的切换对应关系。
在又一种可能的实现方式中，终端设备还可以上报从缺省状态或者回退状态切换到新的频带所需要的切换时延。
在另一种可能的实现方式中，终端设备还可以上报保留原来的状态。即，不会从网络设备调度传输的状态转到回退状态，只会在基站指示的状态上继续驻留。
具体的，可以参照方法200中的步骤201，此处不再赘述。
步骤502，网络设备接收终端设备发送的第六信息，并根据第六信息确定第四信息。
本实施例中，第四信息包括字段#5(第五字段的示例)，字段#5可以用于指示终端设备切换后的第一频段。
在一种可能的实现方式中，第四信息还包括字段#6(第六字段的示例)，字段#6用于指示终端设备接收第五信息，该第五信息用于指示所述终端设备切换后的第二频段。
作为一个示例，第四信息可以为动态调度的DCI，可以在现有DCI0_1或DCI0_0中增加新的bit位。例如，新的bit位占据1bit。当新的bit位为“1”时，表示该时隙中还有针对同一终端设备的另一DCI需要协调调度。“协调调度”可以理解为，需要等待另一DCI解析后，再判定该DCI调度的band/CC的对应通道传输，从而使得终端设备能够根 据目标时隙的完整传输组合状态进行相应的通道参数配置，从而可以减小通道配置错误造成的重配问题。如果新的bit位为0时，表示该时隙中没有针对同一终端设备的别的DCI需要协调调度，因此可以即时开启相应的通道参数进行配置。
终端设备可以根据第四信息和第五信息的指示确定切换前的频段/载波，以及切换后的频段/载波。
基于上述技术方案，通过第四信息可以指示了本时隙上还有别的DCI待检测，从而使得终端设备获取第一个DCI后，需要等待第二个DCI的信息，基于两个DCI判断在被调度进行传输的目标时隙的传输组合状态，因此不需要在不对应的通道上进行参数配置，避免参数重配置问题。
在另一种可能的实现方式中，所述第四信息还包括字段#7(第七字段的示例)，字段#7用于指示字段#5生效的滞后时间，其中，网络设备可以在一个时间段内接收第五信息，第五信息用于指示终端设备切换后的第二频段。可选的，一个时间段可以为符号个数或者时隙个数。例如，一个时间为三个符号，或者一个时隙。
本申请中，“滞后时间”也可以理解为是“时间窗”、“时间段”、“切换时长”、或者“时间偏移量”。例如，本申请中，“滞后时间”例如可以为基站通过RRC信令所预先配置的。
作为一个示例，第四信息可以为动态调度DCI，例如可以在现有DCI0_1或DCI0_0中增加新的bit位。新的bit位用于指示该DCI生效的起始时刻。其中，生效的起始时刻，表示收到该DCI后从该生效的起始时刻起才能进行对应的通道参数配置。例如，该生效的起始时刻可以是通过多个时间窗的索引指示。其中，时间窗也可以理解为滞后时间或切换时长。例如，时间窗可以是基站通过RRC信令预先配置的。例如，在该时间窗内网络设备可以向终端设备发送第五信息。
终端设备可以根据第四信息和第五信息的指示确定切换前的频段/载波，以及切换后的频段/载波。
基于上述技术方案，网络设备通过第四信息指示了本时隙检测到的DCI解析后进行通道参数配置的起始时刻，从而使得终端设备获取第一个DCI后可以不急于配置通道参数，能够在该起始时刻之前获取到第二个DCI，基于两个DCI综合判断在被调度进行传输的目标时隙的传输组合状态，因此不需要在不对应的通道上进行参数配置，避免参数重配置问题。
步骤503，网络设备向终端设备发送第四信息和第五信息。
例如，网络设备可以向终端设备发送动态调度第四信息和第五信息。
步骤504，终端设备接收网络设备发送的第四信息和第五信息，并根据第四信息和第五信息在切换后的频段上传输上行数据。
作为一个示例，假设终端设备当前在通道#1中使用频段#18，在通道#2中使用频段#20。终端设备在时隙#2上接收第四信息，终端设备根据第四信息确定切换后的频段为频段#18，并且确定在时隙#2上需要再接收一个第五信息，需要根据第四信息和第五信息共同确定切换后的频段。终端设备在时隙#2上继续接收第五信息，第五信息指示终端设备切换后的频段为频段#16。假设终端设备在通道#1上支持频段#18和频段#16，在通道#2上支持频段#20和频段#18。则终端设备可以根据第四信息和第五信息共同确定，需要将通道#1 上的频段#18切换到频段#16(例如，第四状态)，将通道#2上的频段#20切换到频段#18(例如，第五状态)。
作为另一个示例，假设终端设备当前在通道#1中使用频段#18，在通道#2中使用频段#20。终端设备在时隙#2的第一个符号上接收第四信息，终端设备根据第四信息确定切换后的频段为频段#18，并且确定需要在时隙#2的第十个符号开始在配置通道#1上的参数。终端设备在时隙#2的第二个符号到第九个符号之间接收第五信息，终端设备根据第五信息确定切换后的频段为频段#16。则终端设备可以根据第四信息和第五信息共同确定，需要将通道#1上的频段#18切换到频段#16(例如，第四状态)，将通道#2上的频段#20切换到频段#18(例如，第五状态)。
应理解，本实施例的方案同样适用于频段上载波之间的切换，此处不再示例。
本申请中，终端设备可以通过第四信息和第五信息，确定需要打断哪个频段并且明确切换后的频段或载波，避免了终端设备的通道对应的频段重配置的问题，减少了时延，提高了数据传输。
可选的，如果第四信息或第五信息中还包括字段#2。例如，终端设备当前在时隙#2上接收第四信息，第四信息中包括字段#2，字段#2可以指示终端设备在第三时隙的第三符号上发送数据，即，可以从时隙#3的第三符号开始使用频段#16、频段#18发送数据。又例如，终端设备当前在时隙#2上接收第五信息，第五信息中包括字段#2，字段#2可以指示终端设备在第三时隙的第三符号上发送数据，即，可以从时隙#3的第三符号开始使用频段#16、频段#18发送数据。
本申请中，终端设备通过第四信息或第五信息可以确定在哪个时隙或者哪些符号上使用切换后的频段/载波发送上行数据，使得终端设备在完成状态切换之后，按照字段#2的指示在特定的时隙上接收数据。可以避免终端设备还没有完成状态之间的切换就接收数据，提高了数据传输性能。
