一种时域资源分配方法及装置
本申请要求于2018年04月04日提交中国专利局、申请号为201810301448.5、申请名称为“一种时域资源分配方法及装置”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
本申请涉及通信技术领域，尤其涉及一种时域资源分配方法及装置。
背景技术
通信系统中，网络设备和用户设备(User Equipment，UE)进行数据传输时，网络设备可以对UE进行调度，例如可以通过控制信息为UE分配数据信道的频域资源和/或时域资源。5G新无线(New Radio，NR)中，数据信道的传输是在部分频域资源(Bandwidth Part，BWP)上，占用的时域符号可以是动态变化的，比如可以从时隙或子帧中第一个符号开始传输,或者其他任意符号开始，而结束符号也可以是在时隙或子帧中的任意位置。数据传输具体使用的时域资源需要UE和网络设备确定，比如可以网络设备指示给UE。而在5G NR中，UE如何根据网络设备的指示确定具体使用的时域资源还有待研究。
发明内容
本申请实施例提供一种时域资源分配方法及装置，提出了一种确定数据信道时域资源的具体方法，能够通过分配合理的默认候选资源，保证数据传输的传输性能。
为达到上述目的，本申请的实施例采用如下技术方案：

在一种可能的设计中，该方法可以包括：确定N个候选时域资源信息，N大于等于1；接收指示信息，用于从N个候选时域资源信息中确定为数据信道分配的时域资源。其中，对于M种帧结构参数中的至少一种帧结构参数，N个候选时域资源信息中的至少一个候选时域资源信息所指示的时域资源与长期演进LTE中下述至少一个信号和/或信道使用的时域资源不同：小区公共参考信号CRS、物理下行控制信道PDCCH、多媒体广播单频网MBSFN、主同步信号PSS、辅同步信号SSS和/或广播信道PBCH；其中，M种帧结构参数中包括以下至少一种帧结构参数：30kHz子载波间隔和普通循环前缀CP，60kHz子载波间隔和普通CP，15kHz子载波间隔和扩展CP，30kHz子载波间隔和扩展CP，和，60kHz子载波间隔和扩展CP。
在该方法中，针对M种帧结构参数中的至少一种，至少一个候选时域资源信息所指示的时域资源与LTE中信号和/或信道使用的时域资源不同。这样，能够避免NR系统和LTE系统在数据传输中的干扰，保证数据传输的传输性能。

具体实施方式
下面结合附图对本申请实施例提供的时域资源分配方法及装置进行详细描述。
本申请提供的技术方案可以应用于包括系统共存场景的各种通信系统，例如当前2G，3G，4G通信系统，5GNR系统，未来演进系统或者多种通信融合系统等等。可以包括多种应用场景，可以包括机器对机器(machine to machine，M2M)、D2M、宏微通信、增强型移动互联网(enhance mobile broadband，eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication，uRLLC)以及海量物联网通信(massive machine type communication，mMTC)等场景，这些场景可以包括但不限于：UE与UE之间的通信场景，网络设备与网络设备之间的通信场景，网络设备与UE之间的通信场景等。本申请实施例提供的技术方案也可以应用于5G通信系统中的UE与UE之间的通信，或网络设备与网络设备之间的通信等场景中。
本申请实施例提供的技术方案可以应用于如图1所示的系统架构中，该系统架构中可以包括网络设备100以及与网络设备100连接的一个或多个UE200。
网络设备100可以是能和UE200通信的设备。网络设备100可以是中继站或接入点等。网络设备100可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的网络设备收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是LTE中的eNB或eNodeB(evolutional NodeB)。网络设备100还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备100还可以是5G网络中的网络设备或未来演进的PLMN网络中的网络设备；还可以是可穿戴设备或车载设备等。
UE200可以是接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动 设备、UE终端、终端、无线通信设备、UE代理或UE装置等。接入终端可以是蜂窝电话、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、个人数字处理(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网络中的终端或未来演进的PLMN网络中的终端等。
应注意，图1所示的系统架构仅用于举例，并非用于限制本申请的技术方案。本领域的技术人员应当明白，在具体实现过程中，该系统架构中还可能包括其他设备，同时也可根据具体需要来配置网络设备100和UE200的数量。
本申请实施例提供的时域资源分配方法和装置，可以应用于用户设备中，该用户设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、以及即时通信软件等应用。并且，在本申请实施例中，时域资源分配方法的执行主体的具体结构，本申请实施例并未特别限定，只要能够通过运行记录有本申请实施例的时域资源分配方法的代码的程序，以根据本申请实施例的时域资源分配方法进行通信即可，例如，本申请实施例提供的时域资源分配方法的执行主体可以是用户设备，或者，是用户设备中能够调用程序并执行程序的功能模块，或者为应用于用户设备中时域资源分配装置，例如，芯片，本申请对此不作限定。
此外，本申请实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
由于未来接入网可以采用云无线接入网(cloud radio access network，C-RAN)架构来实现，一种可能的方式是将传统基站的协议栈架构和功能分割为两部分，一部分称为集中单元(central unit，CU)，另一部分称为分布单元(distributed unit，DU)，而CU和DU的实际部署方式比较灵活，例如多个基站的CU部分集成在一起，组成一个规模较大的功能实体。如图2所示，其为本申请实施例提供的一种网络架构的示意图。如图2所示，该网络架构包括接入网(以无线接入网(radio access network，RAN)为例)设备和用户设备UE。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 (radio remote unit，RRU)相对于基带处理单元(building base band unit，BBU))，RAN设备由一个节点实现，该节点用于实现无线资源控制(radio resource control，RRC)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)等协议层的功能。再如，在一种演进结构中，基带装置可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，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，例如分组数据汇聚层协议层及以上协议层的功能设置在CU，PDCP以下的协议层，例如无线链路控制(radio link control，RLC)和媒体接入控制层等的功能设置在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。
此外，请继续参考图3，相对于图2所示的架构，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，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令/数据可以通过DU发送给UE，或者UE产生的信令/数据可以通过DU发送给CU。DU可以不对该信令/数据进行解析而直接通过协议层封装而透传给UE或CU。以下实施例中如果涉及这种信令/数据在DU和UE之间的传输，此时，DU对信令/数据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物理层(physical layer，PHY)的信令/数据发送给UE，或者，由接收到的PHY层的信令/数据转变而来。在这种架构下，该RRC或PDCP层的信令/数据，即也可以认为是由DU发送的，或者，由DU和射频发送的。
在以上实施例中CU划分为RAN中网络设备，此外，也可以将CU划分为核心网中的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于UE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节点功能的RAN设备。
在本申请中，执行上述时域资源分配方法的可以是网络设备和UE，也可以是应用于网络设备和UE中的装置，例如，芯片，或者其他实现上述时域资源分配方法的装置，本申请实施例对此不进行限定。本文中以网络设备和UE执行上述时域资源分配方法为例进行说明。
NR中可以通过半静态指示方式为UE配置数据信道的候选时域资源(比如时隙和符号的起始位置和/或长度)，然后根据指示信息为UE配置候选时域资源中的一个作为该UE的数据信道的时域资源。但是，如果UE还没有获得候选时域资源，即使接收到指示信息， UE也无法确定具体的时域资源，因此无法和网络设备通过数据信道进行数据传输。
例如，网络设备通过无线资源控制(radio resource control，RRC)信令为UE配置数据信道的候选时域资源。那么在网络设备和UE建立RRC连接之前，UE则无法获取候选时域资源。
还有，如果数据信道是通过回退模式的DCI，比如，下行控制信息格式(DCI format)0-0，和/或，DCI format 1-0调度时；调度数据信道的下行控制信道是通过系统信息无线网络临时标识(system information-RNRI，SI-RNTI)、随机接入无线网络临时标识(random access-RNTI，RA-RNTI)、寻呼无线网络临时标识(paging-RNTI，P-RNTI)或临时小区无线网络临时标识(temporary C-RNTI，TC-RNTI)进行循环冗余校验码(cyclic redundancy code，CRC)加扰时；调度数据信道的下行控制信道不是通过小区无线网络临时标识C-RNTI或配置调度无线网络临时标识CS-RNTI进行CRC加扰时；以及针对随机接入消息Msg3传输的情况，UE均无法获取候选时域资源。此时，若UE需要通过下行数据信道接收网络设备的寻呼消息、系统消息或回退模式的下行控制信息(downlink control information，DCI)调度的数据时，由于UE无法确定下行数据信道的时域资源位置，因此无法接收网络设备发送的寻呼消息、系统消息等。
针对UE无法通过半静态指示方式等获知候选时域资源的场景，NR中提出了预配置默认的(default)候选时域资源的设计。在UE还无法获取半静态指示方式配置的候选时域资源的情况下，可以使用默认的候选时域资源。
本申请提出的时域资源分配方法，设计了一种默认的候选时域资源，UE通过网络设备下发的指示信息，从默认的候选时域资源中确定出为数据信道分配的时域资源。
数据传输可以包括下行数据传输和上行数据传输，下行数据传输可以指网络设备向UE发送数据，上行数据传输可以是指UE向网络设备发送数据。数据信道分为物理下行共享信道(physical downl ink sharing channel，PDSCH)和物理上行共享信道(physical uplink sharing channel，PUSCH)。以下行数据传输为例，网络设备通过物理下行控制信道(physical downlink control channel，PDCCH)向UE发送DCI，UE按照配置的检测周期或检测时刻在控制信道资源集合(control resource set，CORESET)中检测PDCCH，从而获取到DCI中的指示信息，UE可以根据指示信息从默认的候选时域资源中确定出为PDSCH分配的时域资源。PUSCH的时域资源的确定方法与PDSCH类似，本申请实施例以PDSCH为例进行说明。
下面对本申请中涉及的部分术语进行解释说明，以方便读者理解：
1、候选时域资源信息
候选时域资源信息用于指示默认的候选时域资源。一个候选时域资源信息指示一个候选时域资源。可选的，一个候选时域资源信息可以包括K 0、S、L和数据信道的映射类型四个参数。根据K 0、S、L和数据信道的映射类型四个参数可以确定一个候选时域资源。
其中，K 0表示时隙偏移，用于指示数据信道所在的时隙，数据信道所在的时隙具体计算公式如下：
Figure PCTCN2019079570-appb-000001
其中n为调度的DCI所在的时隙，K 0为时隙偏移具体的取值，比如可以是0,1,2,…,7。 μ PDCCH为控制信道的帧结构参数,μ PDSCH为数据信道的帧结构参数，K 0的指示以数据信道的帧结构参数为准。
举例来说，如果控制信道的子载波间隔为15kHz，即μ PDCCH为0；如果数据信道的子载波间隔为30kHz，即μ PDSCH为1；n为1，即时隙1；K 0为1；则数据信道所在的时隙为
Figure PCTCN2019079570-appb-000002
即时隙3。
S表示数据信道在时隙中的起始符号，L表示数据信道在时隙中的符号长度。
PDSCH的映射类型可以包括类型A(Type A)或类型B(Type B)，用于指示解调参考信号(demodulation reference signal，DMRS)所映射至的位置。
可选的，数据信道的映射类型，可以是指下行数据信道的映射类型，也可以是指上行数据信道的映射类型。比如PDSCH的映射类型或PUSCH的映射类型。其中数据信道的映射类型也可以简称为映射类型。
2、帧结构参数
在NR中随着技术的演进，一个载波的不同的频段可以采用不同的帧结构参数，这些参数在标准讨论中统称为numerology。不同的频段可以采用不同的numerology，即理解为采用不同的帧结构。例如不同的帧结构参数可以是不同的子载波间隔(15kHz，30kHz，60kHz)，和/或不同的循环前缀(cyclic prefix，CP)长度(普通CP，扩展CP)，和/或不同的时间单位(1ms，0.5ms，0.25ms)等。帧结构参数可以是指子载波间隔，CP长度，时间单位中的至少一项。
3、本文中的术语“多个”是指两个或两个以上。本文中的术语“第一”和“第二”是用于区别不同的对象，而不是用于描述对象的特定顺序。本文中术语“和/或”，仅仅是一种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这三种情况。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请实施例提供一种时域资源分配方法，可以应用于图1-图3所示的通信系统。如图4所示，该方法可以包括S201-S204：
S201、UE确定N个候选时域资源信息。
具体的，UE确定N个候选时域资源信息，N大于等于1。N个候选时域资源信息中的一个候选时域资源信息用于指示一个时域资源。
可选的，在一种实现方式中，N个候选时域资源信息可以预配置在UE侧。比如，可以协议中预定义N个候选时域资源信息。UE和网络设备可以根据协议确定N个候选时域资源信息。
可选的，在一种实现方式中，N个候选时域资源信息可以由网络设备发送给UE。比如，网络设备通过信令将N个候选时域资源信息发送给UE，信令可以是系统信息，广播信息，还可以是高层信令，比如RRC信令或媒体接入控制(media access control，MAC)信令，也可以是物理层信令，比如DCI等。
具体的，N个候选时域资源信息指示的时域资源可以用于NR中数据传输，N个候选时域资源信息中的至少一个候选时域资源信息所指示的时域资源与LTE中信号和/或信道使用的时域资源不同，即N个候选时域资源信息中的至少一个候选时域资源信息指示的时域资源不包括LTE中发送信号的时频资源。比如，LTE中小区公共参考信号(cell-specific reference signal，CRS)、物理下行控制信道(physical downlink control channel，PDCCH)、多媒体广播单频网(multimedia broadcast single frequency network，MBSFN)子帧、主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal,SSS)和/或广播信道(physical broadcast channel，PBCH)发送信号的时频资源上，NR中不进行数据传输。这样，在LTE系统和NR系统共存的场景下，可以避免LTE系统和NR系统的干扰。
下面以LTE中CRS上发送信号为例，对NR系统中N个候选时域资源信息进行说明。需要说明的是，此处仅以CRS为例进行说明，本领域技术人员可以理解，PDCCH、MBSFN、PSS、SSS和PBCH上发送信号的时域资源占用原理与CRS类似，本申请实施例中不再一一列举，但其内容不应被认为超出本申请范围。根据时频资源特点，设计NR系统中候选时域资源信息，可以仅考虑LTE中CRS、PDCCH、MBSFN、PSS、SSS和PBCH中一种，也可以结合LTE中多种信号和/或信道考虑。比如，在一些时隙上，LTE系统中用于发送CRS信号，设计NR系统中候选时域资源信息时，仅考虑CRS即可；比如，另一些时隙上，LTE系统中可以用于发送CRS和/或PDCCH信号，设计NR系统中候选时域资源信息时，结合考虑CRS和PDCCH。
图5a是LTE中，在普通CP下的4个天线端口的CRS所占的资源单元(Resource element，RE)的图案。其中，天线端口0上占用的RE标记为R 0，天线端口1上占用的RE标记为R 1，天线端口2上占用的RE标记为R 2，天线端口3上占用的RE标记为R 3。图5b是LTE中，在扩展CP下的4个天线端口的CRS所占的RE的图案。其中，天线端口0上占用的RE标记为R 0，天线端口1上占用的RE标记为R 1，天线端口2上占用的RE标记为R 2，天线端口3上占用的RE标记为R 3。LTE中子载波间隔为15KHz，一个子帧是1ms，可以包括2个时隙，普通CP下每个时隙有7个符号，符号编号可以为{0,1,2，…,6}，扩展CP下每个时隙有6个符号,符号编号可以为{0,1,2，…5}。如图5a所示，普通CP情况下，CRS占时隙中的符号为#0，#1和#4；如图5b所示，扩展CP情况下，CRS占时隙中的符号为#0，#1，#3。
可选的，在其他通信系统中，子帧，时隙，符号的定义可以不同，本申请中仅以NR下1个子帧为1ms，一个时隙包括14或12个符号为例说明。针对其他通信系统，本申请也适用，具体的子帧，时隙，符号的定义，本申请不作限定。
NR中一个时隙普通CP下可以包括14个符号，符号编号可以为{0,1,2，…,13}，扩展CP下包括12个符号，符号编号可以为{0,1,2，…,11}，支持的帧结构参数包括15kHz子载波间隔和普通CP，30kHz子载波间隔和普通CP，60kHz子载波间隔和普通CP，15kHz子载波间隔和扩展CP，30kHz子载波间隔和扩展CP，以及60kHz子载波间隔和扩展CP，或者也可以是其他的子载波间隔和CP的组合。如图6a所示为不同的子载波间隔(15kHz，30kHz和60kHz)下，普通CP下，NR中一个子帧1ms的符号示意图。其中，一格代表一个符号。
以普通CP为例，LTE中CRS所占的RE对应NR中的符号分别为：
⑴15KHz下的符号为#0，#1，#4，#7，#8，#11；
⑵30KHz下的符号为#0，#1，#2，#3，#8，#9；
⑶60KHz下的符号为，偶数编号时隙的#0，#1，#2，#3，#4，#5，#6，#7；以及奇数编号时隙的#2，#3，#4，#5。
如图6b所示，标记为x的位置即为，不同的子载波间隔(15kHz，30kHz和60kHz)下，普通CP下，LTE中CRS所占的RE对应NR中的符号位置。
另外，在60KHz,扩展CP下，LTE中CRS所占的RE对应NR中的符号为：
偶数编号时隙的#0，#1，#2，#3，#4，#5，#6，#7；以及奇数编号时隙的#0，#1，#2，#3。
根据上述分析，NR中可用的时域资源可以为LTE中CRS没有占用的时域资源。NR中可用的时域资源可以表示为候选时域资源。如表1所示为针对不同的帧结构参数(包括不同的子载波间隔和/或CP长度)的候选时域资源信息。表1中一行为一个候选时域资源信息。N个候选时域资源信息可以是表1中的至少一项。

具体的，比如，如果预定义的候选时域资源信息为上述表2中的候选时域资源信息，则网络设备和UE可以确定候选时域资源信息为表2，以及确定指示信息的bit。比如，表2中包括16个候选时域资源信息(16行)，需要用4bits指示，例如比特0000代表第一行，0001代表第二行，以此类推。其他候选时域资源信息的情况下，可以与之类似，具体的，在此不作赘述。

上述表1和表2的方式，是不同的帧结构参数可以对应同一组候选时域资源信息；表3-表9是不同的帧结构参数可以对应不同的候选时域资源信息。两种方式中，不同的帧结构参数对应同一组候选时域资源信息的方式，设计简单，网络设备和UE实现的复杂度较低。不同的帧结构参数对应不同的候选时域资源信息的方式，UE确定出的N个候选时域资源信息包括的候选时域资源信息的个数少，可以降低信令开销。在具体实现中，可以根据需要确定不同的帧结构参数使用同一组候选时域资源信息，或者不同的帧结构参数使用不同的候选时域资源信息。本申请实施例对此不进行限定。
具体采用哪种方式，可以是预配置的；也可以是网络设备通过信令发送给UE的，信令可以是系统信息，广播信息，还可以是高层信令，比如RRC信令或MAC信令，也可以是物理层信令，比如DCI等。
可选的，CP长度可以是预配置的，也可以是网络设备通过信令发送给UE的，信令可以是系统信息，广播信息，还可以是高层信令，比如RRC信令或MAC信令，也可以是物理层信令，比如DCI等。
可选的，UE在确定候选时域资源信息时，还可以根据当前数据传输占用的时频资源等确定当前场景。比如，可以包括LNC场景和非LNC场景，LNC场景即LTE系统与NR系统共存的场景。在LNC场景，NR中数据传输的候选时域资源，需要考虑LTE系统信号占用时域资源的情况。需要说明的是，UE确定候选时域资源信息时，可以根据当前场景确定；也可以结合当前场景以及本申请中其他实施例中至少一个实施例的方法确定；对此本申请不作限定。
UE确定候选时域资源信息时，可以根据场景确定候选时域资源信息。
具体的，比如考虑LNC场景，采用第一候选时域资源信息。不考虑LNC场景，采用第二候选时域资源信息。其中，第一候选时域资源信息可以是本申请中设计的候选时域资源信息，第二候选时域资源信息可以是不考虑LNC的情况设计的候选时域资源信息。
可选的，可以针对不同的场景确定不同的候选时域资源信息。当然，根据实际情况，也可以在不同的场景使用相同的候选时域资源信息。
可选的，UE可以根据以下至少一项确定候选时域资源信息：数据传输的频段、调度数据的下行控制信道的搜索空间类型、数据信道的映射类型、调度数据的下行控制信息格式、用于对调度数据的下行控制信道进行循环冗余校验码(cyclic redundancy code，CRC)加扰的无线网络临时标识(radio network tempory identity，RNTI)、数据信道传输的信息类型、携带指示信息的消息类型以及数据信道的调度方式。
针对不同的上述信息中的至少一项，可以确定不同的候选时域资源信息。即可以考虑不同信息情况下的需求设计候选时域资源信息，可以更合理的进行数据资源分配。另外也可以在降低开销的同时满足每种情况下的时域资源分配需求。
可选的，可以根据如下至少一种实现方式确定候选时域资源信息。
在一种实现方式中，UE根据数据传输的频段确定候选时域资源信息。
可选的，针对数据传输的不同频段，UE可以确定不同的候选时域资源信息。
具体的，比如针对1.8G频段上的NR传输会和1.8G频段上的LTE传输同时发生数据传输，因此在1.8G频段上考虑LNC场景，采用第一候选时域资源信息。而针对其他频段，比如2.6G频段上的NR传输不会和LTE传输同时发生，因此不考虑LNC场景，采用第二候 选时域资源信息。在一种实现方式中，UE根据调度数据的下行控制信道的搜索空间类型确定候选时域资源信息。
可选的，针对不同的搜索空间类型，UE可以确定不同的候选时域资源信息。
具体的，比如搜索空间类型可以包括公共搜索空间和用户级搜索空间。公共搜索空间包括：Type0-PDCCH公共搜索空间、Type0A-PDCCH公共搜索空间、Type1-PDCCH公共搜索空间、Type2-PDCCH公共搜索空间以及Type3-PDCCH公共搜索空间中的至少一项。具体的，比如针对Type0-PDCCH公共搜索空间，Type0A-PDCCH公共搜索空间调度的数据传输，可以设计特殊的候选时域资源。针对Type1-PDCCH公共搜索空间，Type2-PDCCH公共搜索空间，Type3-PDCCH公共搜索空间，采用第一候选时域资源信息。而针对用户级搜索空间，可以采用第二候选时域资源信息。
在一种实现方式中，UE根据调度数据的下行控制信息格式确定候选时域资源信息。
下行控制信道PDCCH用于传输下行控制信息DCI，DCI可以进行上行数据的调度，也可以进行下行数据的调度。
可选的，针对不同的调度数据的下行控制信息格式可以确定不同的候选时域资源信息。
具体的，比如针对不同的数据调度可以有不同的DCI格式(DCI format)。比如针对上行数据的调度可以包括DCI format 0_0,DCI format 0_1；针对下行数据的调度可以包括DCI format 1_0,DCI format 1_1。
具体的，比如针对DCI format 0_0或DCI format 1_0调度的数据，UE可以确定候选时域资源信息为第一候选时域资源信息。而针对DCI format 0_1或DCI format 1_1调度的数据，UE可以确定候选时域资源信息为第二候选时域资源信息。
在一种实现方式中，UE根据用于对调度数据的下行控制信道进行CRC加扰的RNTI确定候选时域资源信息。
可选的，针对不同的用于对调度数据的下行控制信道进行CRC加扰的RNTI，UE可以确定不同的候选时域资源信息。
具体的，比如针对不同的数据，网络设备会为UE分配RNTI，在下行控制信道传输时，下行控制信道的CRC会用RNTI进行加扰。可以针对不同的用于对下行控制信道进行CRC加扰的RNTI类型，确定不同的候选时域资源信息。
比如针对系统信息的数据调度的下行控制信道的CRC会用SI-RNTI(system information-RNTI，系统信息无线网络临时标识)加扰。
比如针对寻呼信息的数据调度的下行控制信道的CRC会用P-RNTI(paging-RNTI,寻呼无线网络临时标识)加扰。
比如针对随机接入信息的数据调度的下行控制信道的CRC会用RA-RNTI(random access-RNTI,随机接入无线网络临时标识)加扰。
比如针对随机接入过程中的数据调度的下行控制信道的CRC会用TC-RNTI(temporary cell-RNTI,小区无线网络临时标识)加扰。
比如针对用户专用的数据调度的下行控制信道的CRC会用C-RNTI(cell-RNTI,小区无线网络临时标识)加扰。
比如针对配置调度的数据调度的下行控制信道的CRC会用CS-RNTI(configuredscheduling-RNTI,小区无线网络临时标识)加扰。
比如，针对用于对调度数据的下行控制信道进行CRC加扰的RNTI为SI-RNTI或P-RNTI或RA-RNTI或TC-RNTI采用第一候选时域资源信息；针对用于对调度数据的下行控制信道进行CRC加扰的RNTI为C-RNTI或CS-RNTI，采用第二候选时域资源信息。
在一种实现方式中，UE根据数据信道的映射类型确定候选时域资源信息。
可选的，针对不同的数据信道的映射类型，确定不同的候选时域资源信息。
具体的，比如针对Type B，可以采用第一候选时域资源信息；而针对Type A，可以采用第二候选时域资源信息或特殊设计的候选时域资源信息。
在一种实现方式中，UE根据数据信道传输的信息类型确定候时域资源信息。
可选的，针对数据信道传输的不同的消息类型，确定不同的候选时域资源信息。
可选的，数据信道传输的信息类型可以是系统信息，寻呼信息，随机接入信息(比如随机接入响应或Msg3)，配置传输调度下的数据，用户专用数据，小区级数据中的至少一种。
具体的，比如，网络设备可以向UE发送数据信道，数据信道传输的信息类型可以是剩余系统最小系统信息(surplus minimum system information，RMSI)、回退模式的DCI调度的用户数据，或者随机接入消息Msg3。针对数据信道传输的RMSI、回退模式的DCI调度的用户数据或者Msg3，可以确定不同的候选时域资源信息。比如针对RMSI的数据传输，可以设计针对RMSI的特殊的候选时域资源信息，针对回退模式的DCI调度的用户数据，采用第一候选时域资源信息，而针对Msg 3的数据传输，可以设计针对Msg3的特殊的候选时域资源信息。
在一种实现方式中，UE根据携带指示信息的不同的消息类型确定候时域资源信息。
可选的，针对携带指示信息的不同的消息类型，确定不同的候选时域资源信息。
可选的，携带指示信息的信息类型可以是系统信息，高层信令，物理层信令中的的至少一种。
具体的，比如，网络设备可以在向UE发送剩余系统最小系统信息(surplus minimum system information，RMSI)、回退模式的DCI或者高层信令中携带指示信息。针对RMSI或回退模式的DCI或者高层信令携带指示信息的情况下，可以确定不同的候选时域资源信息。比如针对RMSI携带指示信息的数据传输，可以设计针对RMSI的特殊的候选时域资源信息，针对回退模式的DCI携带指示信息的数据传输，采用第一候选时域资源信息，而针对高层信令携带指示信息的数据传输，可以设计针对特殊的候选时域资源信息。
在一种实现方式中，UE根据数据信道的调度方式确定候选时域资源信息。
可选的，针对不同的数据信道的调度方式，确定不同的候选时域资源信息。
具体的，比如数据信道的调度方式包括：基于时隙(slot-based)调度或非基于时隙(non-slot based)调度。针对non-slot based调度，可以采用第一候选时域资源信息，而针对slot-based调度，可以采用第二候选时域资源信息。
S202、网络设备确定N个候选时域资源信息。
具体的，网络设备确定N个候选时域资源信息，N大于等于1。N个候选时域资源信息中的一个候选时域资源信息用于指示一个时域资源。
可选的，在一种实现方式中，N个候选时域资源信息可以预配置在网络设备侧。比如，可以协议中预定义N个候选时域资源信息。UE和网络设备可以根据协议确定N个候选时域 资源信息。
可选的，在一种实现方式中，网络设备确定N个候选时域资源信息，然后发送给UE。比如，网络设备通过信令将N个候选时域资源信息发送给UE，信令可以是系统信息，广播信息，还可以是高层信令，比如RRC信令或媒体接入控制(Media Access Control，MAC)信令，也可以是物理层信令，比如DCI等。
网络设备确定N个候选时域资源信息的原则和方法与UE确定N个候选时域资源信息的原则和方法相同，此处不再赘述。
需要说明的是，本申请不限定S201和S202的执行顺序。
S203、网络设备向UE发送指示信息。
具体的，网络设备向UE发送指示信息，指示信息用于从N个候选时域资源信息中确定为数据信道分配的时域资源。可选的，指示信息可以是通过系统信息，广播信息携带的，或者，还可以是通过高层信令，比如RRC信令或媒体接入控制(Media Access Control，MAC)信令携带的，或者，也可以是物理层信令携带的，比如DCI等。
比如，指示信息可以是DCI中的bit位，用于表示N个候选时域资源信息中的位置。
可选的，指示信息的bit数可以是根据候选时域资源信息的个数确定。具体的，比如，如果候选时域资源信息的个数为N,则指示信息的bit数可以是N或log 2 N向上取值。
S204、UE接收指示信息。
S205、UE确定为数据信道分配的时域资源。
具体的，UE接收指示信息后，根据确定的N个候选时域资源信息，可以确定出为数据信道分配的时域资源。
可选的，数据信道可以是上行数据信道，也可以是下行数据信道。即本申请中的时域资源分配的方法可以应用于上行数据信道，比如PUSCH，也可以应用于下行数据信道，比如PDSCH，或者也可以应用于其他数据信道的传输，本申请对此不作限定。
比如，UE确定N个候选时域资源信息如表1所示，DCI中的bit位为0010时，则为数据信道分配的时域资源为K 0＝0，S＝8，L＝2，映射类型为Type B确定的时域资源。
比如，UE确定N个候选时域资源信息如表6所示，DCI中的bit位为010时，则为数据信道分配的时域资源为K 0＝0，S＝10，L＝2，映射类型为Type B确定的时域资源。
需要说明的是，如果S201中UE确定出N个候选时域资源信息中N为1，即只有一个候选时域资源信息，那么，UE可以不根据网络设备发送的指示信息确定为数据信道分配的时域资源，而根据候选时域资源信息直接确定为数据信道分配的时域资源。此时，网络设备也确定出N个候选时域资源信息中N为1，可以不向UE发送指示信息。网络设备和UE可以根据实际情况确定是否发送指示信息，本申请实施例对此不进行限定。
本申请实施例提供的时域资源分配方法，针对帧结构参数设计了NR系统中的候选时域资源信息，至少一个候选时域资源信息所指示的时域资源与LTE中信号和/或信道使用的时域资源不同；并通过指示信息从N个候选时域资源信息中确定出为数据信道分配的时域资源。通过本申请实施例提供的时域资源分配方法确定出的时域资源进行数据传输，可以降低LTE系统与NR系统之间的干扰，保证数据传输的传输性能。
