Abstract

本申请提供一种通信方法、装置和系统。通信方法包括：获取第一指示信息和格式信息；根据第一指示信息指示的时间单元中的子时间单元的传输方向以及格式信息指示的子时间单元的传输方向，确定时间单元是否属于聚合时间单元。通过根据第一指示信息和格式信息对时间单元中的子时间单元的传输方向的配置，来确定时间单元是否属于聚合时间单元，当时间单元不属于聚合时间单元时，该时间单元不用于基于聚合技术的数据传输，使得聚合时间单元可以不连续。避免了直接根据DCI格式指示的传输方向以及聚合因子，采用连续时间单元作为聚合时间单元，导致的不利于时延敏感数传输的问题。

具体实施方式
图1为本申请实施例适用的网络架构实施例一的示意图。如图1所示，本实施例 提供的网络架构包括网络设备10和至少一个终端设备20。
其中，网络设备10是一种将终端设备20接入到无线网络的设备，可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是长期演进(Long Term Evolution，简称LTE)中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，或者未来第五代移动通信(the 5th Generation Mobile Communication，5G)网络中的基站，或者工作在高频频段的中继站、接入点、车载设备、可穿戴设备等，本申请在此并不限定。图1示意性的绘出了一种可能的示意，以网络设备10为基站为例进行了绘示。
终端设备20可以是无线终端也可以是有线终端，无线终端可以为向用户提供语音和/或其他业务数据连通性的设备，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。无线终端可以经无线接入网(Radio Access Network，简称RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，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，简称PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，简称SIP)话机、无线本地环路(Wireless Local Loop，简称WLL)站、个人数字助理(Personal Digital Assistant，简称PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)，本申请在此不作限定。图1示意性的绘出了一种可能的示意，以终端设备20为移动电话为例进行了绘示。
在传统的LTE通信系统中，网络设备10与终端设备20之间的数据传输以无线帧(radio frame)为时间单位。一个无线帧包含10个1ms的子帧(subframe)。每个子帧均包括两个时隙(slot)，每个slot包括的符号的个数与子帧中循环前缀(cyclic prefix，CP)的长度相关。
具体地，在正交频分复用(orthogonal frequency division multiplexing，OFDM)系统中，为了最大限度地消除符号间干扰，需要在每两个OFDM符号之间插入保护间隔，该保护间隔长度一般要大于无线信道的最大时延扩展，这样一个符号的多径分量就不会对下一个符号造成干扰。保护间隔内的信号称为循环前缀CP。CP类型可以分为普通CP(Normal CP，NCP)和扩展CP(Extended CP，ECP)，其中ECP的应用场景通常是存在大的时延扩展信道环境中。
如果CP为普通(normal)CP，则每个slot包括7个符号，每个子帧由14个符号组成，例如，每个子帧由序号分别为#0，#1，#2，#3，#4，#5，#6，#7，#8，#9，#10，#11，#12，#13的符号组成。如果CP为扩展(extended)CP，每个slot包括6个符号，每个子帧由12个符号组成，例如每个子帧由序号分别为#0，#1，#2，#3，#4，#5，#6， #7，#8，#9，#10，#11的符号组成。
LTE通信系统中对于一个无线帧中的每个子帧为上行子帧或下行子帧规定了7种固定的帧配置结构，如下表1所示。上行子帧用于进行从终端设备20到网络设备10的数据传输，即上行数据传输。下行子帧用于进行从网络设备10到终端设备20的数据传输，即下行数据传输。
表1
Figure PCTCN2019073778-appb-000001
其中，表1中的D表示下行子帧，U表示上行子帧，S表示特殊子帧。特殊子帧S用于从下行到上行的切换，具体包括部分的下行符号，上下行转换的符号以及部分的上行符号。终端设备20和网络设备10之间进行通信时，帧结构仅能采用如表1中的7种中的任一种。这种固定的帧配置结构在一定程度上限制了终端设备20和网络设备10之间的通信灵活性，不利于短时延业务的传输。
为提高通信灵活性，5G NR通信系统可以支持多种配置参数numerologies。numerology可以通过以下参数信息中的一个或多个定义：子载波间隔，循环前缀CP，时间单位，带宽等。其中，时间单位用于表示时域内的时间长度或时间单元，例如可以为采样点，符号(symbol)，微时隙(mini-slot)，时隙(slot)，多个时隙，子帧，无线帧或帧结构(frame)等。时间单位信息可以包括时间单位的类型，长度，或者结构等。
在5G NR通信系统中，一个无线帧为10ms，包含有10个子帧。一个子帧中包含有至少一个slot，一个slot固定有14个符号。一个子帧中的slot个数和对应的子载波间隔相关，如下表2所示。
表2
μ 一个slot中符号个数 一个帧中slot个数 一个子帧中slot个数
0 14 10 1
1 14 20 2
2 14 40 4
3 14 80 8
4 14 160 16
5 14 320 32
表3
μ 子载波间隔(KHz) 循环前缀CP
0 15 normal
1 30 normal
2 60 Normal，extended
3 120 normal
4 240 normal
其中，表2以CP为normal CP为例，对不同的子载波间隔对应的slot数目进行示例说明。表2中μ表示不同的子载波间隔的索引，子载波间隔与μ的对应关系如上表3所示。例如，当子载波间隔为15kHz的时候，对应的μ的取值为0，CP为normal，一个子帧中slot的个数为1，一个帧中slot个数为10。当子载波间隔为30kHz的时候，对应的μ的取值为1，CP为normal，一个子帧中slot的个数为2，一个帧中slot个数为20。通过修改5G NR通信系统的配置参数，可以提高5G通信系统中的数据传输的灵活性。
在5G NR通信系统中，通信传输进一步支持灵活的时隙结构(slot format)，即1个slot中的符号可全部用于上行数据传输，或者全部用于下行数据传输，或者1个slot中的部分符号用于上行数据传输，部分符号用于下行数据传输。时隙结构可根据时隙格式相关信息(slot format related information，SFI)配置。SFI指示了相应的slot中，每个符号为上行符号、下行符号或未知符号，具体可以如下表4所示。
表4
Figure PCTCN2019073778-appb-000002
Figure PCTCN2019073778-appb-000003
其中，D指示下行符号，U指示上行符号，X指示未知符号。未知符号可以被网络设备10后续的信息指示用于上行传输或下行传输，也可以由终端设备20配置用于上行传输或下行传输，还可以作为上下行切换的时间间隔。与LTE通信系统相比，5G通信系统中每个子帧都可以包含有下行和上行的传输机会，更有利于短时延业务的传输。
时隙聚合技术中数据在一个或多个时隙上进行上行传输或下行传输。采用了时隙聚合技术的数据传输占用了更多的资源，增强了数据传输覆盖，提高了数据传输可靠性。
LTE通信系统中基于时隙聚合技术进行数据传输时，需根据数据传输方向、聚合因子指示的待聚合的时隙数目和表1中的帧配置结构确定可选的帧配置结构，使得帧结构灵活性较差。
在5G NR系统中，网络设备10具体可通过动态的下行控制信息(downlink control information，DCI)进行时隙聚合调度，DCI指示数据传输的方向以及时隙中用于上行/下行传输的符号。DCI可以通过物理下行控制信道(physical downlink control channel，PDCCH)由网络设备10向终端设备20发送。
具体地，网络设备10可通过高层信令，比如无线资源控制(radio resource control，RRC)向终端设备20发送上行时域资源分配表和下行时域资源分配表(time resource allocation表)。上行/下行时域资源分配表中包括至多16行。
其中，如下表5所示的下行时域资源分配表中的每一行包含了如下中的至少一项：下行调度与相应下行数据传输的时间关系(Timing between Downlink assignment and corresponding Downlink data transmission，K0)、时域资源分配信息和调度类型(或PDSCH 映射类型)。表5中示例性的有4行。其中，时域资源分配信息包括起始符号和符号个数。
表5
索引号index K0 起始符号 符号个数 调度类型(PDSCH映射类型)
0 0 2 10 A
1 1 3 8 A
2 0 4 7 B
3 3 2 10 A
具体地，图2为本申请实施例中的下行调度与相应下行数据传输的时间关系的示意图。如图2所示，若网络设备10在时间单位n上通过PDCCH向终端设备发送DCI，在物理下行共享信道(physical downlink share channel，PDSCH)上传输的被该DCI调度的数据对应的时间单位为n+K0。图2中K0取值示例性的为3。为方便描述，以下统称与K0相关的时间单位为时隙，但本申请各实施中所描述的时间单位不仅局限于时隙。
具体地，时域资源分配信息可以指示时域资源，例如指示被调度的数据在一个时间单位内所占用的起始符号和符号个数。例如，当时间单位为时隙，则时域资源分配信息表示了在被调度的时隙中被调度的数据的起始符号索引和调度数据的符号个数。示例性地，时域资源分配信息可以统一编码为起始长度指示值(start length indication value，SLIV)。
示例性地，对于NCP和PDSCH资源映射类型A，在一个时隙内，调度数据起始符号的索引可以为0，1，2，3，调度数据的长度至多14个符号；对于NCP和PDSCH资源映射类型B，在一个时隙内，调度数据起始符号的索引可以为任意一个值，调度数据的长度可以为2，4或7个符号；对于NCP和PUSCH资源映射类型A，在一个时隙内，调度数据起始符号索引为0，调度数据的长度至多14个符号；对于NCP和PUSCH资源映射类型B，在一个时隙内，调度数据起始符号索引为任意一个值，调度数据的长度至多14个符号；对于ECP和PDSCH资源映射类型A，在一个时隙内，调度数据起始符号的索引可以为0，1，2，3，调度数据的长度至多12个符号；对于ECP和PDSCH资源映射类型B，在一个时隙内，调度数据起始符号的索引可以为任意一个值，调度数据的长度可以为2，4或6个符号；对于ECP和PUSCH资源映射类型A，在一个时隙内，调度数据起始符号索引为0，调度数据的长度至多12个符号；对于NCP和PUSCH资源映射类型B，在一个时隙内，调度数据起始符号索引为任意一个值，调度数据的长度至多12个符号；
示例性地，网络设备10向终端设备20发送的DCI中具体可以携带有索引号，索引号指示为被该DCI调度的数据传输所分配的时域资源对应该下行时域资源分配表中的哪一行，从而使得终端设备20可以获悉K0的取值和网络设备10所分配的传输数据的时域资源。示例性的，网络设备10还可通过RRC向终端设备20发送K0的一个取值集合，比如{1，2，3，4}，并在DCI中通知终端设备20的K0具体取值为集合中的哪一，并不再将K0放在时域资源分配表里。
示例性地，终端设备20接收网络设备10通过RRC发送的聚合因子。终端设备20根据聚合因子、DCI指示的K0和SLIV可确定采用聚合时隙技术进行数据传输时占用的用于聚合的聚合时隙。图3为本申请实施例中聚合时隙的示意图。如图3所示， 图3中以聚合因子为4、K0取值为1、起始符号为3、符号个数为8为例对聚合时隙进行了示例性说明。
示例性地，网络设备10向终端设备20发送的DCI中还携带有下行数据传输与相应混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)码本反馈的时间关系(Timing between DL data reception and corresponding acknowledgement，K1)。图4为本申请实施例中的下行数据传输与相应HARQ码本反馈的时间关系的示意图。具体地，若网络设备10在时间单位n上经由PDSCH向终端设备20发送下行数据，终端设备20在时间单位n+K1上向网络设备10传输该下行数据对应的上行反馈信息如上行控制信息(uplink control information，UCI)。图4中K1取值示例性的为3。一般情况下，终端设备20经由PUSCH或者PUCCH向网络设备10传输UCI。网络设备10可以预先配置K1取值集合，比如{1，2，3，4}，并通过RRC信令发送给终端设备。随后向终端设备20发送DCI，用于通知终端设备20为该数据传输分配的K1具体取值为集合中的哪一个。
具体地，上行时域资源分配表中的每一行包含如下中的至少一项：上行调度与相应上行数据传输的时间关系(Timing between UpLink assignment and corresponding UpLink data transmission，K2)、时域资源分配信息。其中，K2指示了从PDCCH到PUSCH的时间间隔，若网络设备10在时间单位n上通过PDCCH向终端设备发送DCI，在物理上行共享信道(physical uplink share channel，PUSCH)上传输的被该DCI调度的数据对应的时间单位为n+K2。时域资源分配信息与下行时域资源分配表中的时域资源信息相同，本申请不再赘述。
参照上述分析，网络设备10配置的时隙结构与网络设备10通过DCI指示的时隙聚合调度均对时隙中的符号用于上行/下行进行了指示，因此，可能存在网络设备10配置的时隙结构与网络设备10通过DCI指示的时隙聚合调度冲突的情况。在NR系统中上述冲突的解决方案为：终端设备根据聚合因子确定连续的时隙作为聚合时隙。但是，采用连续的时隙作为聚合时隙，存在不利于时延敏感数传输的问题，影响了数据传输效率。
为解决上述问题，本申请提出一种通信方法，根据提高了数据传输效率。下面采用详细的实施例，对本申请提供的通信方法进行详细说明。
图5为本申请实施例一提供的通信方法的流程示意图。该方法的执行主体可以为图1中的终端设备20。本实施例涉及通信过程中聚合时隙的获取方法，根据网络设备为终端设备配置的SFI和SLIV同时确定时隙是否为聚合时隙，提高了数据传输效率。如图5所示，该方法包括：
S501、获取第一指示信息和格式信息。
具体地，第一指示信息可以为起始长度指示值SLIV，格式信息可以为时隙格式相关信息SFI。
可选地，终端设备获取SLIV的方式具体包括：
终端设备接收网络设备发送的下行控制信息，下行控制信息中携带有索引号，终端设备根据索引号在DCI的格式指示的传输方向所对应的时域资源分配表中获取SLIV。
示例性地，终端设备在接收DCI时，可根据DCI的格式确定进行上行数据传输或下行数据传输。当DCI的格式指示下行数据传输时，终端设备根据DCI中的索引号，在下行时 域资源分配表中确定SLIV。当DCI的格式指示上行数据传输时，终端设备根据DCI中的索引号，在上行时域资源分配表中确定SLIV。
可选地，终端设备获取SFI的过程具体包括：
终端设备获取网络设备通过RRC信令或下行控制信息发送的SFI。
示例性地，网络设备可以通过半静态方式，如RRC信令向终端设备配置SFI，网络设备还通过RRC信令配置SFI的周期，SFI的可以为0.125ms、0.25ms、0.5ms、1ms、2ms、5ms和10ms等。示例性地，网络设备还可以通过动态方式，如DCI向终端设备配置SFI。例如，终端设备通过检测组内公共下行控制信道Group Common PDCCH获取SFI。一个Group Common PDCCH可以指示一个或多个slot的SFI。
S502、根据第一指示信息指示的时间单元中的子时间单元的传输方向以及格式信息指示的子时间单元的传输方向，确定时间单元是否属于聚合时间单元。
具体地，时间单元可以为帧、子帧、时隙等。本申请以下各实施例中以时间单元为时隙为例，对确定时间单元是否属于聚合时间单元的过程进行说明。
其中，第一指示信息指示的时间单元中的子时间单元的传输方向可以为子时间单元中的待传数据的传输方向，传输方向可以为上行、下行和未知。具体可以由第一指示信息确定时间单元中的部分或全部子时间单元，并由第一指示信息对应的DCI的格式确定该部分或全部子时间单元的传输方向，且传输方向均相同。例如，对于包括14个符号的时隙n，第一指示信息中指示了符号3至符号10的传输方向为下行传输方向。格式信息中指示了时间单元中的各子时间单元的传输方向，例如上行、下行和未知。例如，对于该时隙n，格式信息指示了时隙n中每一个符号的传输方向。本实施例可以根据符号3至符号10在第一指示信息中的传输方向与格式信息中的传输方向是否存在冲突来确定时隙n是否属于聚合时隙。
示例性的，对于任一子时间单元，当第一指示信息指示该子时间单元的传输方向为上行时，若格式信息指示该子时间单元的传输方向为上行或未知，则确定传输方向相同；若格式信息指示该子时间单元的传输方向为下行，则确定传输方向不同。同样的，对于任一子时间单元，当第一信息指示该子时间单元的传输方向为下行时，若格式信息指示该子时间单元的传输方向为下行或未知，则确定传输方向相同；若格式信息指示该子时间单元的传输方向为上行，则确定传输方向不同。对于任一子时间单元，当第一指示信息指示该子时间单元的传输方向为未知时，则确定传输方向相同。
具体地，当确定时间单元属于聚合时间单元，确定时间单元的传输方向为DCI的格式指示的传输方向，属于聚合时间单元的所有时间单元具有相同的传输方向。在进行数据传输时，数据占用所有的聚合时间单元进行传输，增加了数据传输占用的资源，提高了数据传输可靠性。具体地，当确定时间单元不属于聚合时间单元，则在进行数据传输时，不占用该时间单元，用于聚合的时间单元可以为不连续的。终端设备可根据格式信息指示的该时间单元中的各子时间单元的传输方向，传输数据或指令等，提高了数据传输的灵活性。
具体地，上述根据第一指示信息和格式信息分别指示的子时间单元的传输方向确定时间单元是否用于聚合的过程，示例性的可以包括如下几种实现方式：
第一种实现方式：
当第一指示信息指示的时间单元中的至少一个子时间单元的传输方向与格式信息指示的该些至少一个子时间单元的传输方向相同，确定时间单元属于聚合时间单元。
可选地，时间单元中存在至少N个子时间单元，分别记为子时间单元1至N。当第一指示信息为子时间单元1至N配置的传输方向与格式信息为子时间单元1至N配置的传输方向一一相同时，认为该时间单元属于聚合时间单元。其中，N为正整数。
可选地，还可以为当第一指示信息指示的时间单元中的配置了传输方向的各子时间单元的传输方向与格式信息指示的该些各子时间单元的传输方向一一相同，则确定时间单元属于聚合时间单元。
此时，聚合时间单元的传输方向与第一指示信息为时间单元中的子时间单元指示的传输方向相同。
第二种可能的实现方式：
当第一子时间单元占时间单元中的至少一个子时间单元的比例达到M，确定时间单元属于聚合时间单元；其中，第一指示信息指示的第一子时间单元的传输方向与格式信息指示的第一子时间单元的传输方向相同，M的取值在[0，1]范围内。
可选地，将时间单元中第一指示信息指示的传输方向与格式信息指示的传输方向相同的子时间单元记为第一子时间单元，当时间单元中第一子时间单元占时间单元中的至少一个子时间单元的比例达到M时，确定时间单元属于聚合时间单元。可选地，该些至少一个子时间单元可以为第一指示信息中指示了传输方向的子时间单元。其中，M为0至1中的任意实数。当M为1表示时间单元中的至少一个子时间单元均为第一子时间单元。
此时，聚合时间单元的传输方向与第一指示信息为时间单元中的子时间单元指示的传输方向相同。
第三种可能的实现方式：
当时间单元中第二子时间单元的数目少于P，确定时间单元属于聚合时间单元；其中，第一指示信息指示的第二子时间单元的传输方向与格式信息指示的二子时间单元的传输方向不同，P为正整数。
可选地，将时间单元中第一指示信息指示的传输方向与格式信息指示的传输方向不同的子时间单元记为第二子时间单元，当时间单元中第二子时间单元的数目未达到P时，确定时间单元属于聚合时间单元；当时间单元中第二子时间单元的数目达到P时，确定时间单元不属于聚合时间单元。
此时，聚合时间单元的传输方向与第一指示信息为时间单元中的子时间单元指示的传输方向相同。
第四种可能的实现方式：
当第三子时间单元占时间单元中的至少一个子时间单元的比例小于Q，确定时间单元属于聚合时间单元；其中，第一指示信息指示的第三子时间单元的传输方向与格式信息指示的第三子时间单元的传输方向不同，Q的取值在[0，1]范围内。
可选地，将时间单元中第一指示信息指示的传输方向与格式信息指示的传输方向不同的子时间单元记为第三子时间单元，当时间单元中第三子时间占时间单元中的至少一个子时间单元的比例小于Q时，确定时间单元属于聚合时间单元；当时间单元中第三子时间占时间单元中的至少一个子时间单元的比例不小于Q时，确定时间单元不属于聚合时间单元。 可选地，该些至少一个子时间单元可以为第一指示信息中指示了传输方向的子时间单元。
此时，聚合时间单元的传输方向与第一指示信息为时间单元中的子时间单元指示的传输方向相同。

在上述实施例的基础上，本申请实施例还提供一种通信方法。图6为本申请实施例二提供的通信方法的流程示意图。本实施例中终端设备还接收指示聚合数目的第二指示信息，根据聚合数目确定聚合时间单元的数量。如图6所示，通信方法还包括：
S601、获取第二指示信息，第二指示信息指示聚合数目。
具体地，终端设备接收网络设备发送的第二指示信息，第二指示信息示例性的可以为聚合因子，指示了聚合数目。在网络设备和终端设备之间进行数据传输时占用的时间单元的数目为聚合因子指示的聚合数目。可选地，网络设备通过RRC信令向终端设备发送第二指示信息。
S602、根据聚合数目确定聚合时间单元的数量。
具体地，在根据第二指示信息确定了聚合数目后，确定属于聚合时间单元的时间单元的数量是否达到聚合数目，若达到，则确定聚合时间单元的数量为第二指示信息指示的聚合数目；若未达到，则确定当前聚合时间单元的数量，并再次执行图5所示实施例中的判断时间单元是否聚合时间单元的步骤。可选地，本实施例中的S601和S602可以在图5所示实施例中的S502之后执行。
本实施例提供的通信方法包括：获取第二指示信息，第二指示信息指示聚合数目，根据聚合数目确定聚合时间单元的数量。本实施例中终端设备根据第二指示信息确定聚合数目，并根据聚合数目确定聚合时间单元的数量，根据聚合时间单元的数量确定用于数据传输的聚合时间单元。
可选地，在上述实施例的基础上，本申请实施例还提供一种通信方法，对当DCI的格式指示进行下行数据传输时，确定当前时间单元是否属于聚合时间单元的过程进行说明。图7为本申请实施例三提供的通信方法的流程示意图。如图7所示，通信方法包括：

S703、根据下行控制信息中的上行反馈时间单元K1，以及处理时间单元间隔，确定截止时间单元。
具体地，DCI中携带有上行反馈时间单元K1，处理时间单元间隔为终端设备处理下行数据所需要占用的时间间隔。因此，在时间单元K1之前的时间间隔内的时间单元均无法作为聚合时间单元。因此，可根据K1和处理时间单元间隔，确定截止时间单元，截止时间单元在K1之前。示例性地，处理时间单元间隔可以为终端设备和网络设备预定义的，也可以为网络设备通过信令向终端设备发送的。
S704、确定属于聚合时间单元的时间单元的数目未达到聚合数目且当前时间单元在截止时间单元之前。
示例性地，在判断当前时间单元是否属于聚合时间单元之前，若确定已经属于聚合时间单元的时间单元的数目已达到聚合数目，则可结束聚合时间单元的确定过程。同时，若确定当前时间单元不在截止时间单元之前，则说明不存在时间单元可以用于进行下行数据传输，否则终端设备无法在上行反馈时间单元K1上传反馈信息，因此，同样结束聚合时间单元的确定过程。
S705、根据第一指示信息指示的当前时间单元中的子时间单元的传输方向以及格式指示指示的当前时间单元中的子时间单元的传输方向，确定当前时间单元是否属于聚合时间单元。
示例性地，本实施例中的确定当前时间单元是否属于聚合时间单元的具体方式与图5所示实施例中的确定时间单元是否属于聚合时间单元的具体方式相同，本申请不再赘述。

S804、将聚合时隙数目加1，判断聚合时隙数目是否达到聚合因子指示的数目；若是，则结束；若否；则执行S805。
示例性地，当第i时隙属于聚合时隙时，将聚合时隙数目加1。聚合时隙数目的初始数值为0。判断修改后的聚合时隙数目是否达到聚合因子指示的数目。若达到，则获取了聚合时隙所需的所有时隙。若未达到，在继续获取用于聚合的聚合时隙。
S805、判断DCI的格式是否指示下行数据传输；若是，则执行S807；若否，则执行S806。
示例性地，根据DCI的格式判断进行上行数据传输或下行数据传输。
S806、将i加1，并执行S804。
示例性地，当根据DCI的格式判断进行上行数据传输时，将i增加1，例如判断第二时隙是否为聚合时隙。
S807、将i加1，判断第i时隙是否为截止时隙；若是，则结束；若否；则执行S804。
示例性地，当根据DCI的格式判断进行下行数据传输时，还需进一步判断第i时隙是否为截止时隙，截止时隙的获取方式具体如上述图7实施例所示，本申请不再赘述。
本实施例中根据第一指示信息和格式信息对时间单元中的子时间单元的传输方向的配置，来确定时间单元是否属于聚合时间单元，当时间单元不属于聚合时间单元时，该时间单元不用于基于聚合技术的数据传输，使得聚合时间单元可以不连续。避免了直接根据DCI格式指示的传输方向以及聚合因子，采用连续时间单元作为聚合时间单元，导致的不利于时延敏感数传输的问题。

本申请另一方面还提供一种时频资源分配表，下面对时频资源分配表进行详细说明。以下各实施例中的时频资源分配表可以作为图5至图9所示方式实施例中的时频资源分配表，用于确定K0/K2、SLIV信息等。
可选地，网络设备在终端设备完成初始接入之后，在RRC信令中为终端设备的上行调度配置上行时域资源分配表，为终端设备的下行调度配置下行时域资源分配表。时域资源分配表可以如表5所示，包含比如4行，5列内容。其中，5列参数分别为表格行数的索引号，K0，调度数据起始符号、调度数据的符号个数，调度类型。时域资源分配表还可以包含4行，4列内容。其中，4列参数分别为表格行数的索引号，K0，调度数据的起始符号和长度SLIV、资源映射类型。因此，网络设备在上行调度和下行调度的下行控制指示DCI中秩序携带2比特的指示信息即可指示终端设备时域资源分配的信息。
一种确定时域资源分配表的方法，为根据不同的CP类型确定不同的表格。对fallback DCI的时域资源调度而言，预定义对应的表格。对non-fallback DCI的时域资源调度而言，通过RRC信令配置对应的表格。其中，通过考虑不同的CP类型和数据的映射类型，可以进一步约束SLIV的取值范围，从而用较少比特数的标识来指示资源分配，节省了开销。
在终端设备初始接入过程中，网络设备无法通过RRC信令为终端设备配置时域资源分配表，需要预定义时域资源分配表。可选地，为上行回退DCI，比如DCI format0_0预定义上行时域资源分配表。当表格中使用SLIV指示数据调度的起始符号和符号个数，则表格为4列，如果使用数据起始符号列和符号个数列分别指示，则表格为5列。表格行数的选择与预定义的K0/K2、SLIV值的个数相关，表格行数可以为4或8等，因此在DCI中仅占用2比特或3比特即可指示终端设备时域资源分配的信息。
可选地，可针对不同的CP类型设置不同的时域资源分配表。比如分别为NCP和ECP预定义一张表格，如表6和表7，或预定义一张NCP和ECP共用的表格，如表8所示。为NCP和ECP预定义不同的表格可以减少DCI中时域指示信息的比特数开销，为NCP和ECP预定义一张表格可以减少UE的处理复杂度。
对于NCP上行回退DCI表格，K2的值可以为1,2,3,4,5,6,7,8，K2的取值考虑了不同 UE的不同数据处理能力，从而满足不同的UE能力和回退需求。当PUSCH映射类型为B时，PUSCH的起始符号可以为0,1,2,3,4，符号个数可以为2,4,7,8,10,12,14。对于时隙调度，一个时隙内除了控制信道所占的符号，其它符号都用来做数据传输，从而最大化了UE的实际可用资源，对于非时隙调度，符号个数可以为2,4,7，减少调度时延。当PUSCH映射类型为A时，PUSCH的起始符号可以为0，符号个数可以为2,4,8,10,12,14，多个可能的PUSCH符号个数，最大化了调度的灵活性。如表6所示，第二列为K2的值，K2取值为2，当PUSCH映射类型为B时，PUSCH的起始符号为0或2，符号个数可以为2,4,7,10。当PUSCH映射类型为A时，PUSCH的起始符号为0，符号个数为12。
对于NCP下行回退DCI表格，K0的值可以为0，K0取值为0可以减少UE接收数据的处理时间，减少数据调度的时延，当PDSCH映射类型为B时，PDSCH的起始符号位置可为0,1,2,3,4，符号个数可以为2,4,7。根据下行控制信道可能占用的符号个数确定PDSCH可能的起始位置和PDSCH映射规则B可以满足的调度符号个数确定符号个数，从而最大化调度的灵活性。当PDSCH映射类型为A时，PDSCH的起始符号位置可以为0,1,2,3，符号个数可以为7,9,11,14，一个时隙内除了控制信道所占的符号，其它符号都用来做数据传输，从而最大化了UE的实际可用资源。如表9所示，第二列为K0的值，K0取值为0，当PDSCH映射类型为B时，PDSCH的起始符号为0，符号个数可以为2,4,7。当PDSCH映射类型为A时，PDSCH的起始符号为0，符号个数为12。
对于ECP上行回退DCI表格，K2的值可以为1,2,3,4,5,6,7,8。当PUSCH映射类型为B时，PUSCH的起始符号可以为0,1,2,3,4，符号个数可以为2,4,6,8,10,12。当PUSCH映射类型为A时，PUSCH的起始符号可以为0，符号个数可以为2,4,8,10,12。不同参数的选取规则和有益效果与NCP上行回退DCI相同。如表7所示，第二列为K2的值，K2取值为2。当PUSCH映射类型为B时，PUSCH的起始符号为0，2，符号个数可以为2,4,6,8。当PUSCH映射类型为A时，PUSCH的起始符号为0，符号个数为10。
对于ECP下行回退DCI表格，第二列为K0的值，K0的值可以为0，当PDSCH映射类型为B时，PDSCH的起始符号位置可为0,1,2,3,4，符号个数可以为2,4,6；当PDSCH映射类型为A时，PDSCH的起始符号位置可以为0,1,2,3，符号个数可以为5,7,8,9,10,12。不同参数的选取规则和有益效果与NCP下行回退DCI相同。
对于NCP和ECP共用上行回退DCI表格，第二列为K2的值，K2的值可以为1,2,3,4,5,6,7,8，当PUSCH映射类型为B时，PUSCH的起始符号可以为0,1,2,3,4，符号个数可以为2,4,6,7,8,10,12,14；当PUSCH映射类型为A时，PUSCH的起始符号可以为0，符号个数可以为2,4,8,10,12,14。不同参数的选取规则和有益效果与NCP上行回退DCI相同。
对于NCP和ECP共用下行回退DCI表格，第二列为K0的值，K0的值可以为0，当PDSCH映射类型为B时，PDSCH的起始符号位置可为0,1,2,3,4，符号个数可以为2,4,6,7，当PDSCH映射类型为A时，PDSCH的起始符号位置可以为0,1,2,3，符号个数可以为8,10,12,14。不同参数的选取规则和有益效果与NCP下行回退DCI相同。

可选地，为下行回退DCI，比如DCI format1_0预定义下行时域资源分配表。当表格中使用SLIV指示数据调度的起始符号和符号个数，那么表格为4列，如果使用数据起始符号列和符号个数列分别指示，那么表格为5列。表格行数的选择与预定义的K0/K2、SLIV的取值的个数相关，表格行数可以为4或8等，在DCI中仅需使用2比特或3比特即可指示终端设备时域资源分配的信息。可选地，可针对不同的CP类型设置不同的时域资源分配表。比如分别为NCP和ECP预定义一张表格，如表9和表10，或预定义一张NCP和ECP共用的表格，如表11。表9至表11如下所示：

对于RRC配置的时域资源分配表格，NCP和ECP可以对应相同或不同的SLIV公式，从而可以为终端设备配置NCP时域资源分配表格一个和ECP时域资源分配表格一个，不同CP类型对应的调度数据起始符号个数和调度数据长度确定SLIV值的集合不同，终端设备根据CP类型确定时域资源分配表格，或配置一个NCP和ECP共用的时域资源分配表格。
可选的，如果NCP和ECP使用相同的SLIV公式，那么该公式可以为：
if(L-1)≤7 then
SLIV＝14·(L-1)+S
else
SLIV＝14·(14-L+1)+(14-1-S)
where0＜L≤14-S
其中，S指示起始符号start，L指示符号个数length。
如果NCP和ECP使用不同的SLIV公式，那么NCP使用的公式可以为：
if(L-1)≤7 then
SLIV＝14·(L-1)+S
else
SLIV＝14·(14-L+1)+(14-1-S)
where0＜L≤14-S,
ECP使用的公式可以为：
if(L-1)≤6 then
SLIV＝12·(L-1)+S
else
SLIV＝12·(12-L+1)+(12-1-S)
where0＜L≤12-S
其中，S指示起始符号start，L指示符号个数length。
可选的，对于RRC配置的时域资源分配表格，因为物理上行数据共享信道PUSCH和物理下行数据共享信道PDSCH的时域资源分配中起始符号的索引和调度数据的长度有不同的取值范围，用于指示SLIV值的比特数可能不相同，比如物理下行数据共享信道时域资源分配表格中SLIV的值使用6比特表示，上行数据共享信道时域资源分配表格中SLIV的值使用7比特表示，然而使用SLIV公式生成的最大SLIV值是大于63的，即不能直接使用6比特来表示SLIV值。考虑到SLIV可能的个数是小于等于64的，因此为了降低开销，即可以用6bit或者更少的bit指示时域资源分配，本发明定义一个参数index和SLIV值之间的映射规则，在RRC配置的时域资源分配表格中，使用该参数来指示SLIV值。
可选地，NCP和ECP可以对应不同的参数index与SLIV值映射规则。具体的该参数index与SLIV映射规则可以通过表格确定。
参数index与SLIV值之间的映射可以是区分NCP和ECP分别定义，也可以是预定义NCP和ECP共用的映射规则。
比如，对于PDSCH映射规则A，NCP和ECP使用相同的SLIV公式，使用相同或不同的时域资源配置表格，使用相同的表格是指高层信令中只配置一张表格，使用不同的时域资源配置表格是指高层信令中为NCP和ECP分别配置一张表格，和相同的参数index与SLIV值映射规则，如表27所示中的至少一行。
对于PDSCH映射规则B，NCP和ECP使用相同的SLIV公式，使用相同或不同的时域资源配置表格，使用相同的映射规则，如表20所示中的至少一行，或使用不同的映射规则，如表18和表19所示中的至少一行。
对于PUSCH映射规则A，NCP和ECP使用过相同的SLIV公式，使用相同或不同的时域资源配置表格，使用相同的参数index与SLIV值映射规则，如表32所示中的至少一行。
对于PUSCH映射规则B，NCP和ECP使用相同的SLIV公式，使用相同或不同的时域资源配置表格，使用相同的映射规则，如表33所示中的至少一行。
