具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
首先，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)终端设备：可以是能够接收网络设备调度和指示信息的无线终端设备，无线终端设备可以是指向用户提供语音和/或数据连通性的设备，或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(如，radio access network，RAN)与一个或多个核心网或者互联网进行通信，终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话，手机(mobile phone))、计算机和数据卡，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、平板电脑(Pad)、带无线收发功能的电脑等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)， 移动站(mobile station)、移动台(mobile station，MS)、远程站(remote station)、接入点(access point，AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station，SS)、用户端设备(customer premises equipment，CPE)、终端(terminal)、用户设备(user equipment，UE)、移动终端(mobile terminal，MT)等。终端设备也可以是可穿戴设备以及下一代通信系统，例如，5G通信系统中的终端设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的终端设备等。
(2)网络设备：是无线网络中的设备，例如网络设备可以为将终端接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为基站。目前，一些RAN设备的举例为：5G通信系统中的新一代基站(generation Node B，gNodeB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wi-Fi)接入点(access point，AP)等。另外，在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。此外，在其它可能的情况下，网络设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请实施例中，为终端设备提供无线通信功能的装置称为网络设备。
(3)帧结构参数：是指通信系统所采用的参数(numerology)。例如可以是指空口中的一系列物理层参数。一个BWP可以对应一个numerology。其中，NR系统可支持多种numerology，多个numerology可以同时使用。numerology可以包括以下参数信息中的一个或多个：子载波间隔，循环前缀(cyclic prefix，CP)的信息，时间单位的信息，带宽等。CP的信息可以包括CP长度和/或者CP类型。例如，CP可以为常规CP(normal CP，NCP)，或者扩展CP(extended CP，ECP)。时间单位用于表示时域内的时间单元，例如可以为采样点、符号、微时隙(mini-slot)、时隙(slot)、子帧(subframe)或者无线帧等等。时间单位的信息可以包括时间单位的类型、长度或者结构等。例如，numerology可以包括子载波间隔和CP，如表1所示，表1给出了NR系统中目前可以支持的、由子载波间隔和CP定义的numerology：
表1
μ 子载波间隔＝2 μ·15(kHz) CP类型
0 15 常规(normal)
1 30 常规
2 60 常规或扩展(extended)
3 120 常规
4 240 常规
其中，μ用于确定子载波间隔，例如，μ＝0时，子载波间隔为15kHz，μ＝1时，子载波间隔为30kHz。以子载波间隔为例，若终端支持子载波间隔15kHz和30kHz，则网络设备可以为终端分配一个子载波间隔为15KHz的BWP，和一个子载波间隔为30KHz的BWP， 终端根据不同的场景和业务需求，可以切换到不同的BWP上传输信号。当终端支持多个BWP时，其中不同的BWP对应的numerology可以相同也可以不同。
其中，子载波间隔可以为大于等于0的整数。例如可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz等。子载波间隔，是正交频分复用(orthogonal frequency division multiplexing，OFDM)系统中，频域上相邻的两个子载波的中心位置或峰值位置之间的间隔值。例如，LTE系统中的子载波间隔为15KHz，NR系统的子载波间隔可以是15kHz，或30kHz，或60kHz，或120kHz等。
需要说明的是，对于独立组网的NR，6GHz及以下频段对应子载波间隔包括15KHz、30KHz、60KHz，同步信号块子载波间隔为15KHz或30KHz。6GHz以上频段对应子载波间隔包括120KHz和60KHz，同步信号块子载波间隔为120KHz或240KHz。可以理解，上述6GHz及以下频段可以称为低频或频率1(frequency 1，FR1)，具体的频率范围可以为450MHz–6000MHz，6GHz以上频段可以称高频或频率2(frequency 2，FR2)，具体的频率范围可以为24250MHz–52600MHz。
需要指出的是，在LTE(Long Term Evolution，长期演进)和NR(new radio，新无线)中，小区是高层的概念，载波是物理层的概念。小区和载波有对应关系，如在LTE中，一个小区可以被配置为包含一对上下行载波，或只包含一个下行载波。在NR中，一个小区可以被配置为包含一对上下行载波，或只包含一个下行载波，或包含一个下行载波，一个上行载波和一个补充上行载波(supplementary uplink，SUL)。因为载波和小区的对应关系，一个载波属于一个小区，配置了小区就能找到相应的载波；反之亦然。因此在本发明中并不严格区分小区和载波的概念，二者在不引起混淆的情况下可以混用。
示例性的，本申请所提供的实施例适用于多小区场景，比如载波聚合场景或者双连接场景，所谓多小区场景是将两个或更多的成员载波(Component Carrier，CC)聚合在一起以支持更大的传输带宽，上述载波可以由一个或多个基站提供。该成员载波也可以称为载波。例如，多小区，可以包含主小区(Primary Cell，PCell)、辅小区(Secondary Cell，SCell)、或主辅小区(primary secondary cell,PSCell)。具体地，Pcell可以是初始连接建立时，终端与基站进行通信的小区，或RRC连接或重配置时的小区，或在切换过程中由基站或终端确定，主要用于实现基站与终端间的RRC通信。Scell可以是RRC重配置时基站新增为终端提供服务的小区，例如Scell与终端间可以主要用于业务相关通信，不涉及RRC通信。
主小区组(MCG，Master cell group)和辅小区组(SCG，Secondary cell group)是双链接(DC，Dual connectivity)下的概念，可以简单理解为UE首先发起随机接入的Cell所在的Group就是MCG。如果没有进行双链接，也就没有MCG和SCG的概念。或者也可以理解为，如果没有进行双链接，那么该小区组就对应MCG。在MCG下，可能会有很多个Cell，其中有一个用于发起初始接入的小区，这个小区称为PCell。顾名思义，PCell是MCG里面最“主要”的小区。MCG下的PCell和MCG下的SCell通过载波聚合(CA，Carrier aggregation)技术联合在一起。主成员载波(Primary component carrier，PCC)是PCell对应的CC，辅成员载波(Secondary component carrier，SCC)是Scell对应的CC。同样地，在SCG下也会有一个最主要的小区，也就是PSCell，也可以简单理解为在SCG下发起初始接入的小区。SCG下的PSCell和SCG下的SCell也是通过CA技术联合在一起。
可以理解，本申请还可用于旁链路通信的通信场景。该通信场景中可以包括网络设备 以及一个或多个终端设备(比如终端设备1、终端设备2)。网络设备与终端设备1、终端设备2可以通过空口资源进行数据传输，终端设备1和终端设备2之间可以通过旁链路资源进行数据传输。以上行传输为例，网络设备与终端设备1或终端设备2进行上行数据传输的数据信道可以承载在上行(uplink，UL)载波(比如第一UL载波)中。终端设备1和终端设备2进行数据传输的数据信道可以承载在SL载波中。在一个示例中，SL载波可以为UL载波(比如第二UL载波)，第一UL载波和第二UL载波可以为同一载波。
本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A、同时存在A和B、单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC或ABC。
以及，除非有特别说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两种信息的优先级或者重要程度等的不同。
图1为本申请实施例适用的一种网络架构示意图。如图1所示，终端设备130可接入到无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它设备通信，如可以与其它终端设备通信。该无线网络包括无线接入网(radio access network，RAN)设备(或者说网络设备)110和核心网(core network，CN)设备120，其中RAN设备110用于将终端设备130接入到无线网络，CN设备120用于对终端设备进行管理并提供与外网通信的网关。应理解，图1所示的通信系统中各个设备的数量仅作为示意，本申请实施例并不限于此，实际应用中在通信系统中还可以包括更多的终端设备130、更多的RAN设备110，还可以包括其它设备。
CN中可以包括多个CN设备120，当图1所示的网络架构适用于5G通信系统时，CN设备120可以为接入和移动性管理功能(access and mobility management function，AMF)实体、会话管理功能(session management function，SMF)实体或用户面功能(user plane function，UPF)实体等，当图1所示的网络架构适用于LTE通信系统时，CN设备120可以为移动性管理实体(mobility management entity，MME)和服务网关(serving gateway，S-GW)等。
图2为本申请实施例适用的又一种网络架构示意图。如图2所示，该网络架构包括CN设备、RAN设备和终端设备。其中，RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成在基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE通信系统中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
RAN设备和终端设备之间的通信遵循一定的协议层结构，例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data  convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能；用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种可能的实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol，SDAP)层。
RAN设备可以由一个节点实现RRC、PDCP、RLC和MAC等协议层的功能，或者可以由多个节点实现这些协议层的功能。例如，在一种演进结构中，RAN设备可以包括CU和DU，多个DU可以由一个CU集中控制。如图2所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
图3为本申请实施例适用的又一种网络架构示意图。相对于图2所示的网络架构，图3中还可以将CU的控制面(control plane，CP)和用户面(user plane，UP)分离，分成不同实体来实现，分别为CP CU实体(即CU-CP实体)和UP CU实体(即CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端设备，或者终端设备产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端设备或CU。以下实施例中如果涉及这种信令在DU和终端设备之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端设备，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频装载发送的。
上述图1、图2或图3所示意的网络架构可以适用于各种无线接入技术(radio access technology，RAT)的通信系统中，例如可以是LTE通信系统，也可以是5G(或者称为新无线(new radio，NR)通信系统，也可以是LTE通信系统与5G通信系统之间的过渡系统，该过渡系统也可以称为4.5G通信系统，当然也可以是未来的通信系统。本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端设备或网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。
基于上述图1、图2或图3所示意的网络架构中，本申请实施例提供一种通信方法，用于提高传输性能，以满足灵活多变的业务量和/或覆盖要求较高的通信需求。
在基于OFDM(英文：Orthogonal Frequency Division Multiplexing，缩写：OFDM，中文：正交频分复用)的无线通信系统中，为了抵抗信道多径引起的符号间干扰，采用了在符号中增加循环前缀(英文：Cyclic Prefix，缩写：CP)的设计。其中，多径的时延扩展越大，对CP的需求越长。针对一种子载波间隔，为了满足不同场景的时延扩展需求，可以采用普通CP(英文：Normal Cyclic Prefix，缩写：NCP)或扩展CP(英文：Extended Cyclic Prefix，缩写：ECP)两种CP类型。其中，NCP和ECP为两种长度不同的CP类型，ECP长度比NCP长度更长，CP开销更高。
在数据传输中，随着用户信道时延扩展的变化，对于CP类型的需求可能不同，因此需要进行不同CP类型之间的灵活配置。如图4所示，不同小区对应的子载波间隔分别为30kHz和60kHz，时间单元的粒度以时隙为例，由于不同CP类型的时隙所占用的时间长度不同，会造成帧内时隙无法对齐，从而无法实现在不同小区内的正常通信。
本申请文件的各个实施例中，两个小区时隙对齐的概念包括以下几种：多小区中低子载波间隔对应的时隙0的起始位置与高子载波间隔对应的时隙边界是对齐的，或者多小区中主小区/主辅小区对应子载波间隔的时隙0的起始位置与辅小区对应子载波间隔的时隙边界是对齐的。或者，多小区中低子载波间隔对应的每个时隙的起始位置与高子载波间隔对应的时隙边界是对齐的。又或者，多小区中主小区/主辅小区对应子载波间隔的每个时隙的起始位置与辅小区对应子载波间隔的时隙边界是对齐的。如果多小区的子载波间隔相同，CP类型相同或不同，那么时隙对齐的概念可以认为是：多小区中主小区/主辅小区对应子载波间隔和CP的时隙0的起始位置与辅小区对应子载波间隔和CP的时隙边界是对齐的；或者，多小区中辅小区对应子载波间隔和CP的时隙0的起始位置与主小区/主辅小区对应子载波间隔和CP的时隙边界是对齐的。
示例性的，时隙0为每个系统帧中的第一个时隙，该时隙的起始位置与系统帧的起始位置对齐，该时隙的持续时间与时隙对应的子载波间隔和CP类型有关。或者，时隙0为每个子帧中的第一个时隙，该时隙的起始位置与该子帧的起始位置对齐，该时隙的持续时间与时隙对应的子载波间隔和CP类型有关。
示例性地，本申请的实施例提供的方法可以包括：获取不同小区内时间单元的偏移。或者，获取至少一个子载波间隔和至少一个时间单元，根据上述子载波间隔和时间单元确定不同小区内时间单元的偏移。一种方式为，终端设备接收来自网络设备的上述偏移；或者，网络设备向终端设备发送上述偏移。其中，网络设备确定偏移的技术方案可以参考下文描述。又一种方式为，根据参考子载波间隔对应的时间单元、小区1和小区2的子载波间隔，确定小区1和小区2的时间单元的偏移。再一种方式为，根据小区1和小区2的子载波间隔、小区1和小区2中的时间单元的最小值，确定小区1和小区2的时间单元的偏移。可选的，上述偏移可以为小区1和小区2中载波间的时间单元偏移。采用上述方法，终端设备或网络设备通过不同小区内时间单元的偏移，有效保证小区间的时间单元对齐和多小区下的传输性能，比如，可以有效增加上下行传输机会或者有效避免信道质量较差而导致的上下行传输错误，便于满足灵活多变的业务量和/或覆盖要求较高的通信需求。
下面结合说明书附图对本申请的技术方案作进一步地详细描述。

501，获取第一小区的第一子载波间隔，第二小区的第二子载波间隔，第一小区的第一时间单元和第二小区的第二时间单元。
可以理解，上述第一时间单元可以用于终端设备或网络设备在第一小区内的通信，第二时间单元可以用于终端设备或网络设备在第二小区内的通信。上述通信包括信令、消息、业务或数据的发送或接收。
相应地，上述获取动作的执行主体可以为终端设备或网络设备。可选的，上述获取方式可以是预定义的，或者通过消息或信令由网络设备和终端设备之间进行交互。例如，网络设备在一条或多条消息中向终端设备指示上述至少一个子载波间隔或至少一个时间单元；或者，终端设备接收来自网络设备的一条或多条消息，上述消息指示至少一个子载波间隔或至少一个时间单元。又如，终端设备无需接收网络设备的指示，即可自行根据预先定义得知上述至少一个子载波间隔或至少一个时间单元。
进一步，上述网络设备向终端设备发送的消息或信令可以为高层信息，比如广播消息，系统消息，接入过程中的下行消息，无线资源控制(英文：Radio Resource Control，缩写：RRC)信令，媒体访问控制(英文：Media Access Control Control Element或者Medium Access Control Control Element，MAC CE)，或者物理层控制信令等。或者，该消息或信令还可以为物理层下行控制信息(英文：Downlink Control Information，缩写：DCI)，等等，本申请不做限定。
示例性地，时间单元是指一种时间单位对应的一个单元。该时间单位是指用于进行信息传输的时域内的时间单位或者调度单位，该时间单位时域内包含整数个符号，例如该时间单位可以是指子帧，也可以是指时隙(slot)，还可是指无线帧、微时隙(mini slot或sub slot)、多个聚合的时隙、多个聚合的子帧、符号等等，还可以是指传输时间间隔(英文：Transmission Time Interval，缩写：TTI)，本申请不做限定。其中，一种时间单位的一个或多个时间单元时域内可以包含整数个另一种时间单位的时间单元，或者一种时间单位的一个或多个时间单元时域内长度等于整数个另一种时间单位的时间单元长度和，例如，一个微时隙/时隙/子帧/无线帧内包含整数个符号，一个时隙/子帧/无线帧内包含整数个微时隙，一个子帧/无线帧内包含整数个时隙，一个无线帧包含整数个子帧等，也可以存在其余包含 举例，本申请不做限定。
在本申请中，时间单元可以通过索引、标识或其他途径，对不同时间单元进行区分、标记或计数。
示例性的，第一时间单元对应第一子载波间隔，第二时间单元对应第二子载波间隔。时间单元的类型不同时，第一时间单元或第二时间单元包含的个数不同。比如时间单元为子帧的时候，第一时间单元和第二时间单元都为1ms，再比如时间单元为时隙的时候，第一时间单元或第二时间单元可以对应一个或多个不同长度的时隙。举例而言，第一子载波间隔为60kHz NCP，第一时间单元可能包含两个不同的长度的时隙；第二子载波间隔为30kHz，第二时间单元包含一个长度的时隙。
502，根据所述第一时间单元和所述第二时间单元，所述第一子载波间隔和第二子载波间隔，确定所述第一时间单元和所述第二时间单元之间的偏移。
相应地，上述确定动作的执行主体可以为终端设备或网络设备。
示例性的，根据上述第一时间单元和第二时间单元中的最小时间单元，以及所述第一子载波间隔和第二子载波间隔，确定第一时间单元和第二时间单元之间的偏移。
或者，根据上述第一子载波间隔和第二子载波间隔的较大值，以及该较大子载波间隔对应的时间单元，确定第一时间单元和第二时间单元之间的偏移。
可以理解，以时间单元为时隙举例，上述最小时间单元取第一时隙和第二时隙所占用时间长度的较小者。例如，第一时隙为0.5ms，第二时隙为0.251ms和0.249ms，那么两者中最小时隙为0.249ms。
本实施例中，一种可能性是先根据第一和第二子载波间隔的大小，确定待选子载波间隔。随后，根据待选子载波间隔确定上述第一时隙和第二时隙中的较小值，结合待选子载波间隔和上述时隙较小值，获取第一和第二时隙的偏移。另一种可能性是先确定第一时隙和第二时隙的较小者，再确定第一和第二子载波间隔中的待选子载波间隔，随后获取第一和第二时隙的偏移。采用上述方法，终端设备或网络设备通过不同小区内时间单元的偏移，有效保证小区间的时间单元对齐和多小区下的传输性能，比如，可以有效增加上下行传输机会或者有效避免信道质量较差而导致的上下行传输错误，便于满足灵活多变的业务量和/或覆盖要求较高的通信需求。
可选地，该第一与第二时间单元之间的偏移可以是该第一时间单元与第二单元的偏移值和偏移方向。例如，向前或向右偏移表示向时间增加或时间向前推进的方向偏移，向后或向左偏移表示向时间减小或时间向后回退的方向偏移。类似的，正向偏移表示向时间增加的方向偏移，负向偏移表示向时间减小的方向偏移。
可选地，偏移值的粒度可以为子帧，时隙，还可以是指无线帧、微时隙、符号、采样点等。
具体地，该偏移值的粒度可以是计算第一时间单元和第二时间单元之间的偏移值时使用的单位。以时隙为偏移值的粒度举例，第二时间单元为第一时间单元在时域上向前或向后移动2个时隙。具体的，当第二时隙相对于第一时隙向前或向右移动2个时隙，则在时域上第二时隙位于第一时隙前面或右面，且第一时隙和第二时隙中间间隔2个时隙。相应的，第一时隙位于第二时隙的后面或左面。可以理解，偏移值可以为上述粒度的整数倍或非整数倍。例如，第二时隙也可以相对于第一时隙偏移2.5个时隙，本申请对此不做限定。
可选的，本实施例还包括：获取第一小区的第一循环移位和第二小区的第二循环移位， 根据所述第一时间单元和所述第二时间单元，所述第一子载波间隔、所述第二子载波间隔、所述第一循环移位和所述第二循环移位，确定所述第一时间单元和所述第二时间单元之间的偏移。示例性的，第一时间单元根据第一子载波间隔和第一循环移位确定，第二时间单元根据第二子载波间隔和第二循环移位确定，比如第一子载波间隔为60kHz，第一循环移位为NCP，那么第一时间单元为0.251ms和0.249ms，第二子载波间隔为60kHz，第二循环移位为ECP，那么第二时间单元为0.25ms。再比如，第一子载波间隔30kHz，第一循环移位为NCP，那么第一时间单元为0.5ms，第二子载波间隔为15kHz ECP，第二循环移位为ECP，那么第二时间单元为0.5ms。
进一步的，可以获取第一小区的第一循环移位和第二小区的第二循环移位，根据所述第一时间单元和所述第二时间单元中的较小值，所述第一子载波间隔、所述第二子载波间隔、所述第一循环移位和所述第二循环移位，确定所述第一时间单元和所述第二时间单元之间的偏移。
在本申请中，循环移位包括正常循环移位(normal cyclic prefix,NCP)和扩展循环移位(entened cyclic prefix,ECP)，主要是指上述两种CP具有不同开销的CP类型。例如，ECP开销大于NCP，对于同一种子载波间隔ECP的CP长度大于NCP的CP长度。本申请以LTE或5G的NCP或ECP举例，当NCP和ECP的长度和本发明举例不同时也在本申请的保护范围。
本申请中，如无特殊说明，NCP符号是指该符号的CP类型为NCP，ECP符号是指该符号的CP类型为ECP。NCP时隙或者时隙为NCP是指该时隙中的符号全部为NCP符号，ECP时隙或者时隙为ECP是指该时隙中的符号全部为ECP符号。其中，时隙由整数个符号组成。又如，小区或载波的循环移位为ECP指该小区或载波中配置的BWP对应子载波间隔中最小值或最大值对应的循环移位为ECP，小区或载波的循环移位为NCP指该小区或载波中配置的BWP对应子载波间隔中最小值或最大值对应的循环移位为NCP。如果一个小区或载波中的配置的BWP对应的子载波间隔中最小值或最大值对应的CP类型包括ECP和NCP，那么可以预定义一个规则，比如预定义该小区或载波对应的CP为NCP或预定义该小区或载波对应的CP为ECP。
LTE(long term evolution，长期演进)系统的子载波间隔(subcarrier spacing,SCS)为15kHz，最大支持20MHz带宽。在通信系统中定义了一个基本时间，该基本时间为Ts，该基本时间也可以称为采样时间。Ts＝1/(SCS×FFT Size)，其中FFT Size为FFT(fast fourier transform，快速傅里叶变换)的大小，也可以理解为每个OFDM(orthogonal frequency division multiplexing，正交频分复用)符号的有用符号的采样数。OFDM符号可简称为符号，每个符号包括CP和有用符号。20MHz带宽的LTE系统对应的FFT Size为2048，LTE系统对应的Ts等于1/(15000×2048)＝1/30720000秒。
如图6所示，LTE系统的帧的时长等于10ms，子帧的时长Tsubframe等于1ms，每个时隙的时长等于0.5ms，每个时隙包括若干个OFDM符号。LTE系统采用了2种循环前缀(cyclic prefix，CP)类型，一种为常规循环前缀(normal cyclic prefix，NCP)，另一种为扩展循环前缀(extended cyclic prefix，ECP)。如图6所示，在采用NCP时，LTE系统的每个时隙包括7个符号。在这7个符号中，第一个符号的CP的时长Tcp等于160×Ts，其余6个符号的CP的时长Tcp等于144×Ts，每个符号的有用符号的时长Tu等于2048×Ts。在采用NCP时，LTE系统的CP开销约为6.67％。如图6所示，在采用ECP时，LTE系统 的每个时隙包括6个符号，每个符号的CP的时长Tcp-e等于512×Ts，每个符号的有用符号的时长Tu等于2048×Ts。在采用ECP时，LTE系统的CP开销为20％。ECP能够满足时延较大的场景，但是其占用的系统开销较NCP要大。
NR(new radio，新无线)系统作为一种最新的通信系统，可以支持多种SCS，即在NR系统中同一时刻可以存在一种SCS或者并存多种SCS，或者在不同时刻可以存在多种SCS。NR系统支持不同SCS之间的切换，即NR系统可以将当前使用的SCS切换成另一种SCS。NR系统的SCS为2n×15kHz，其中n为整数。在NR系统中，一般将15kHz作为参考SCS。
NR系统也采用了NCP和ECP。NR系统在采用NCP时，可以考虑不同SCS实现在时域上对齐。如图7所示，SCS＝30KHz对应的2个采用NCP的符号与SCS＝15KHz对应的1个采用NCP的符号在时域上对齐；SCS＝60KHz对应的2个采用NCP的符号与SCS＝30KHz对应的1个采用NCP的符号在时域上对齐；SCS＝120KHz对应的2个采用NCP的符号与SCS＝60KHz对应的1个采用NCP的符号在时域上对齐。即对于SCS不小于15kHz时，在采用NCP时，SCS＝2n×15kHz对应的2n个符号的时长等于1个SCS＝15kHz对应的符号的时长，即该2n个采用NCP的符号的时长相对于参考SCS对应的1个采用NCP的符号的时长是按比例的压缩的(scalable)，该2n个采用NCP的符号的CP的时长也是相对于参考SCS对应的1个采用NCP的符号的CP的时长按比例压缩的。在采用ECP的场景下，可以考虑通过按比例压缩SCS＝15KHz对应的采用ECP的符号来获得其他SCS对应的采用ECP的符号，其CP开销为20％，开销较大，导致传输效率偏低。
故，本申请实施例提出的技术方案，通过确定不同时间单元之间的偏移值，实现不同小区与终端设备的正常通信。
如表1所示，针对LTE系统，列举若干时间单元的对应关系。其中，以子载波间隔为15kHz为例，一个子帧内的时隙个数为2，采样点Ts为15360。当CP类型为NCP时，一个时隙内符号个数为7；当CP类型为ECP时，一个时隙内符号个数为6。
Figure PCTCN2019116313-appb-000001
如表2所示，针对NR系统，同样列举若干时间单元的对应关系，NR系统中还引入了T C的概念，来表示时域的时间单元，T C＝1/(f max·N f)，其中f max＝480·10 3Hz，N f＝4096。常量κ＝T S/T C，其中T S＝1/(f ref·N f,ref),f ref＝15·10 3Hz，N f,ref＝2048。因此表2中15KHz NCP的一个子帧内时隙长度可以为(144+2048)*14+16*2＝30720Ts，也可以为((144+2048)*14+16*2)*κ*T C＝30720T S，本发明中使用κ表示偏移长度时，默认最后会乘以T C。

可选的，以下针对第一小区为主小区或主辅小区，第二小区为辅小区，第一子载波间隔为第一小区中配置的BWP中对应的最小或最大子载波间隔，第一循环移位为第一子载波间隔对应的循环移位，第二子载波间隔为第二小区中配置的BWP中对应的最小或最大子载波间隔，第二循环移位为第二子载波间隔对应的循环移位，示例性描述几种可能性：
1、当第一子载波间隔和第二子载波间隔均为60kHz，所述第一循环移位为ECP，所述第二循环移位为NCP时，上述偏移值为M*(16Ts+NL)+n*(L+8Ts)。其中，M是时间区域的个数，N是所述时间区域内的第二小区的第二时间单元的个数，L是第一小区的第一时间单元和上述第二小区的第二时间单元中的较小值对应的采样点个数，该较小值对应的循环移位为所述第二循环移位，n表示超出所述时间区域的所述第二单元的个数，Ts为采样点；或，
当第一子载波间隔和第二子载波间隔均为60kHz，所述第一循环移位为NCP，所述第二循环移位ECP时，所述偏移值为M*(NL+16Ts)+(n(L+8Ts))或M*(NL+16Ts)+(n(L-8Ts))，其中，M是时间区域的个数，N是所述时间区域内的第一小区的第一时间单元的个数，L是第一小区的第一时间单元和第二小区的第二时间单元中的较小值对应的采样点个数，所述较小值对应的循环移位为所述第一循环移位，n表示超出所述时间区域的所述第一时间单元的个数，Ts为采样点。例如，n表示超出所述时间区域整数倍的所述第一时间单元的个数。
2、当所述第一循环移位和所述第二循环移位中至少一个为ECP时，所述偏移值为M*NL+nL，其中，M是时间区域的个数，N是所述时间区域内第一小区的时间单元和第二小区的时间单元中的较小值的个数，L是所述较小值对应的采样点个数，所述较小值对 应的循环移位为ECP，n表示超出所述时间区域的所述第一时间单元和第二时间单元的最小时间单元的个数。例如，n表示超出所述时间区域整数倍的所述第一时间单元和第二时间单元的最小时间单元的个数。

可以理解，上述N，L，M，n均为非负整数。其中，当n为零值时，本申请中涉及偏移值的公式，可以认为n自始至终不存在。例如，n表示超出时间区域整数倍的第一时间单元或第二时间单元的个数。
示例性的，上述时间区域内的第一个所述第一时间单元的起始位置和第一个所述第二时间单元的起始位置，与所述时间区域的起始位置对齐。
进一步的，上述时间区域的时间长度可以为0.5ms，或0.5ms的整数倍。本实施例中，时间单元时隙为例，不同小区的时隙在该时间区域内满足首尾对齐。例如，主小区内0.5ms的时隙为a个，辅小区内0.5ms的时隙为b个，那么上述a个第一时隙的时间总长和b个第二时隙的时间总长相同。或者，a个第一时隙中在时域上的第一个的起始位置与b个第一时隙在时域上的第一个的起始位置对齐，且与时间区域的起始位置对齐，a个第一时隙中在时域上的最后一个的结束位置与b个第二时隙在时域上的最后一个的结束位置对齐，且与时间区域的结束位置对齐。n的取值可以为总时隙长度与时间区域的长度之差，再除以单个时隙长度的结果。
以下示例性的，结合具体场景，列举几种实现方案。
第一种、如图8所示，主小区和辅小区的SCS均为15kHz。其中，主小区中CP类型为ECP，辅小区中CP类型为NCP。
LTE支持15kHz的ECP，因此主小区可以理解为LTE的载波，辅小区可以理解为NR的载波。在该场景中，就主小区而言，ECP对应的1ms内的时隙个数为2，每个时隙的长度为0.5ms。就辅小区而言，NCP对应的1ms内的时隙个数为1，每个时隙的长度为1ms。辅小区相对于主小区的时隙偏移值，可以用M*NL+nL来表示。其中指示偏移的单位为采样点，偏移方向可以使用信令或消息指示。或者，使用正负M*NL+nL来表示偏移方向和偏移值。具体而言，正M*NL+nL表示辅小区相对于主小区的时隙偏移值向右偏移M*NL+nL个采样点，负M*NL+nL表示辅小区相对于主小区的时隙偏移值向左偏移(M*NL+nL)个采样点。其中，M是0.5ms的正整数倍，表示具有M个0.5ms的时间长度；N是0.5ms内的最短时隙的个数，L是0.5ms内最短时隙所对应的采样点个数。例如，该最短时隙对应的子载波间隔和CP类型为15kHz和ECP。本申请实施例中，M可以通过网络设备发送给终端设备，L可以通过预定义规则获取。
第二种、主小区的SCS为15kHz，辅小区的SCS为30kHz。其中，主小区中CP类型为ECP，辅小区中CP类型为NCP。
LTE支持15kHz的ECP，因此主小区可以理解为LTE的载波，辅小区可以理解为NR的载波。在该场景中，就主小区而言，ECP 1ms内的时隙个数为2，每个时隙的长度为0.5ms。就辅小区而言，NCP对应的1ms内时隙的个数为2，每个时隙的长度为0.5ms。辅小区载波相对于主小区的时隙偏移值，可以用M*NL+nL来表示，其中，指示偏移的单位为采样点，偏移方向可以使用信令或消息指示。例如，使用正负M*NL+nL来表示，比如正M*NL+nL表示向右偏移(M*NL+nL)个采样点，负M*NL+nL表示向左偏移(M*NL+nL)个采样点。其中，M是0.5ms的正整数倍，表示具有M个0.5ms的时间长度；N是0.5ms内的时隙个数，L是0.5ms内最短时隙所对应的采样点个数。本实现方案中，上述时隙对应的子载波间隔和CP类型为15kHz和ECP，或30kHz和NCP。
第三种、主小区的SCS为15kHz，辅小区的SCS为60kHz。其中，主小区中CP类型为ECP，辅小区中CP类型为NCP。
LTE支持15kHz的ECP，因此主小区可以理解为LTE的载波，辅小区可以理解为NR的载波。在该场景中，就主小区而言，ECP 1ms内的时隙个数为2，每个时隙的长度为0.5ms。就辅小区而言，1ms内时隙的个数为4，其中第一个时隙和第三个时隙长度比第二个时隙和第四个时隙的长度多16个采样点。上述第一至第四时隙可以理解为基于时域上时隙的使用时间或时间顺序排列。以下就不同偏移方向定义两种情况：辅小区载波相对于主小区的时隙偏移值，且指示向右偏移，可以用M*(NL+16Ts)+nL来表示。或者，辅小区载波相对于主小区的时隙偏移值，且指示向左偏移，可以用M*(NL+16Ts)+(nL+16Ts)来表示。其中，M是0.5ms的正整数倍，表示具有M个0.5ms的时间长度；N是0.5ms内的时隙个数，L是0.5ms内最短时隙所对应的采样点个数。本实施例中，上述时隙对应的子载波间隔和CP类型为60kHz和NCP，且对应1ms内的第二和第四个时隙的长度。n为不足0.5ms的时隙个数，对于向右偏移的实现方案，n大于0时，一般需要加上16Ts。本申请实施例中，M，n可以通过网络设备发送给终端设备，L可以通过预定义规则获取。
第四种、主小区的SCS为15kHz，辅小区的SCS为60kHz。其中，主小区中CP类型为ECP，辅小区中CP类型同样为ECP。

另一种可能性为，当主小区为NR载波，则时隙长度为1ms，1ms内有1个时隙，此时，辅小区相对于主小区的时隙偏移值，与主该场景中主小区为LTE载波相同，本文不再赘述。
第六种、主小区的SCS为30kHz，辅小区的SCS为60kHz。其中，主小区中CP类型为NCP，辅小区中CP类型为ECP。
本场景中，30kHz的NCP对应的主小区为NR载波，1ms内有两个时隙，第一个时隙比第二个时隙长16Ts。60kHz的ECP对应的辅小区为NR载波，1ms内时隙的个数为4，每个时隙的长度为0.25ms。
此时，辅小区相对于主小区的时隙偏移值，可以用M*NL+nL来表示，其中，指示偏移的单位为采样点，偏移方向可以使用信令或消息指示。或者，使用正负M*NL+nL来表示偏移量和偏移方向。比如，正M*NL+nL表示向右偏移M*NL+nL个采样点，负M*NL+nL表示向左偏移M*NL+nL个采样点。其中，M是0.5ms的整数倍，表示具有M个0.5ms的时间长度，N是0.5ms内的时隙个数，L是0.5ms内最短时隙对应的采样点个数，该时隙对应的子载波间隔和CP类型为60和kHz ECP。其中，M可以通过网络设备发送给终端设备，L可以通过预定义规则获取。
第七种、主小区的SCS为30kHz，辅小区的SCS为15kHz。其中，主小区中CP类型为NCP，辅小区中CP类型为ECP。
本场景中，30kHz的NCP对应的主小区可以为NR载波，1ms内有两个时隙，每个时隙0.5ms。15kHz的ECP对应的辅小区为LTE载波，1ms内时隙的个数为2，每个时隙的长度为0.5ms。

第八种、如图9所示，主小区的SCS为60kHz，辅小区的SCS为15kHz。其中，主小区中CP类型为NCP，辅小区中CP类型为ECP。
本场景中，60kHz的NCP对应的主小区可以为NR载波，1ms内有四个时隙，其中第一个时隙和第三个时隙的时间长度比第二个和第四个时隙的时间长度多了16Ts。15kHz的ECP对应的辅小区为LTE载波，1ms内时隙的个数为2，每个时隙的长度为0.5ms。辅小区载波相对于主小区的时隙偏移值，且指示向右偏移，可以用M*(NL+16Ts)+(nL+16Ts)来表示；或者，如果向左偏移，可以用M*(NL+16Ts)+nL来表示。其中，指示偏移的单位为采样点，偏移方向可以使用额外的信令指示。其中，M是0.5ms的整数倍，表示具有 M个0.5ms的时间长度，N是0.5ms内的时隙个数，L是0.5ms内最短时隙对应的采样点个数，该时隙对应的子载波间隔和CP类型为60kHz和NCP，n为不足0.5ms的时隙个数。对于向左偏移的情况，一般n大于0时，偏移值计算公式中会加上16Ts。本申请实施例中，M，n可以通过网络设备发送给终端设备，L可以通过预定义规则获取。
第九种、主小区的SCS为60kHz，辅小区的SCS为15kHz。其中，主小区中CP类型为ECP，辅小区中CP类型为NCP。

第十二种、主小区的SCS为60kHz，辅小区的SCS同样为60kHz。其中，主小区中CP类型为ECP，辅小区中CP类型同样为ECP。
以下描述第九至第十二种场景中任意一种的实现方案：
辅小区载波相对于主小区的时隙偏移值，可以用M*NL+nL表示。其中，指示偏移的单位为采样点，偏移方向可以使用信令或消息指示。例如，使用使用正负M*NL+nL来表示偏移方向。具体而言，正M*NL+nL表示向右偏移M*NL+nL个采样点，负M*NL+nL表示向左偏移M*NL+nL个采样点。其中M是0.5ms的整数倍，表示具有M个0.5ms的时间长度，N是0.5ms内的时隙个数，L是0.5ms内最短时隙对应的采样点个数，该时隙所对应的SCS和CP类型为60kHz和ECP。
第十三种、如图10所示，主小区的SCS为60kHz，辅小区的SCS同样为60kHz。其中，主小区中CP类型为ECP，辅小区中CP类型为NCP。
