技术领域
本公开涉及通信技术领域，并且更具体地，涉及一种上行免授权传输的配置方法及设备。
背景技术
全球5G标准制定机构3GPP启动了一个5G新空口研究项目，希望能制定一个基于OFDM的全新5G无线空口标准，5G新空口(New Radio，NR)由此产生。5G NR是基于OFDM的全新空口设计的全球性5G标准，也是下一代非常重要的蜂窝移动技术基础。
与以往的移动通信系统相比，未来5G移动通信系统需要适应更加多样化的场景和业务需求。NR系统的主要场景包括移动宽带增强eMBB、大规模物联网mMTC和超高可靠超低时延通信URLLC，这些场景对系统提出了高可靠、低时延、大带宽、广覆盖等要求。对于某些场景的业务，要求低延时和高可靠的传输。针对这样的业务需求，NR系统支持免授权传输(grant-free)方式，以减少信令交互流程，保证低时延要求。
目前，在NR系统中，上行免授权传输(UL grant-free)可采用类似于UL半静态调度方式(Semi-persistent scheduling，SPS)的配置框架，即采用等间隔的半静态资源配置。NR系统增加了对更加灵活的数值配置(numerology)或调度粒度的配置，以适用于新型业务的需求。但是，如果仅采用基于LTE的UL SPS框架，grant-free传输不适用于不同的数值配置(numerology)和更短的调度时间粒度(如mini-slot或symbol级别的粒度)。
为解决该问题，LTE系统针对低时延的业务引入了更短的TTI(sTTI，shorter TTI)和更短的处理时间(sPT，shorten processing time)，可以 支持以更短的调度时间粒度进行传输的配置。具体为，基于LTE的numerology，在LTE的正常TTI内配置多个更短的TTI，则该更短的TTI称为sTTI；所述LTE的正常TTI，在时域上为1毫秒。sTTI在频域上采用与LTE相同的子载波间隔。
然而，NR系统既可采用基于LTE的numerology，也可采用更高的子载波间隔以获得更短的TTI长度，则基于sTTI对UL grant-free进行配置的方法仍然无法支持NR系统中灵活的Numerology的配置。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。部件可根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
在本说明书中使用的术语，如系统帧、子帧、时隙、符号等，在本领域也经常一一对应的使用system frame、subframe、slot、symbol等来替代， 中文和英文的具有相同的含义。
应当理解，本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，简称为“GSM”)系统、码分多址(CodeDivision Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband CodeDivision Multiple Access，简称为“WCDMA”)通用分组无线业务(General Packet RadioService，简称为“GPRS”)系统、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time DivisionDuplex，简称为“TDD”)、通用移动通信系统(Universal Mobile TelecommunicationSystem，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability forMicrowave Access，简称为“WiMAX”)通信系统，以及未来的5G通信系统等。
应当理解，本公开实施例的技术方案还可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，简称为“SCMA”)系统，当然SCMA在通信领域也可以被称为其他名称。进一步地，本公开实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，简称为“OFDM”)、滤波器组多载波(Filter Bank Multi-Carrier，简称为“FBMC”)、通用频分复用(Generalized Frequency Division Multiplexing，简称为“GFDM”)、滤波正交频分复用(Filtered-OFDM，简称为“F-OFDM”)系统等。
本公开结合终端设备描述了各个实施例。终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端设备可以指用户设备(User Equipment，简称为“UE”)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称为“SIP”)电话、无线本地环路(Wireless Local Loop，简称为“WLL”)站、个人数字处理(Personal Digital Assistant，简称为“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，未来5G网络中的终端设备等。
本公开结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base Transceiver Station，简称为“BTS”)，也可以是WCDMA系统中的基站(NodeB，简称为“NB”)，还可以是LTE系统中的演进型基站(Evolutional Node B，简称为“eNB”或“eNodeB”)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络设备等。
应当理解，本公开实施例所述上行免授权传输至少包括以下几种情况：
(1)网络设备预先分配并告知终端设备多个免授权传输资源；终端设备有上行数据传输需求时，从网络设备预先分配的多个免授权传输资源中选择至少一个免授权传输资源，使用所选择的传输资源发送上行数据。
(2)终端设备在不需要网络设备授权的情况下进行上行免授权数据传输。相对的，网络设备授权可以指，网络设备接收到终端设备发送上行调度请求后，向终端设备发送上行授权，其中所述上行授权指示了分配给终端设备的上行传输资源。
(3)一种竞争传输方式，具体地可以指多个终端在预先分配的相同的时频资源上同时进行上行免授权数据传输，而无需基站进行授权。
在NR系统中进行上行免授权传输时，由于NR系统既可采用基于LTE的numerology，也可采用更高的子载波间隔以获得更短的TTI长度，则相关技术中基于sTTI对UL grant-free进行配置的方法仍然无法支持NR系统中灵活的Numerology的配置。
当然，为了支持NR系统针对新型业务的不同Numerology或多种调度时间粒度的配置，也可以配置更多的UL grant-free传输资源，以减小传输冲突的几率。但是这种方法需要占用较多的资源，会造成资源的利用率下降。
为保证UL grant-free传输适用于不同Numerology和/或时间粒度，本公开实施例提出一种UL grant-free基于不同Numerology和/或时间粒度的资源配置方法。
需要指出，本公开实施例中所涉及的标号S100、S200和S300，仅具有对处理步骤进行标识的作用，并不限定各编号的步骤之间的先后顺序关系。具体的，S100和S200是终端侧的步骤标识，S300网络侧的步骤标识；终端侧S100和S200之间也没有必然的先后顺序关系。
以下结合具体实施例对本公开的具体实现进行详细描述：
图1为本公开实施例一种上行免授权传输的配置方法终端侧流程示意图。如图1所示，一种上行免授权传输的配置方法，包括：
S100，根据当前配置参数获取上行免授权传输的传输位置；
S200，基于所述传输位置，获取对应的子帧时隙，在所述子帧时隙上向网络侧发起上行免授权传输；
其中，所述配置参数包括如下参数中的一种或多种：
起始位置、子帧内部偏移量和传输周期；其中，所述起始位置包括通过系统帧号和子帧号联合指示的起始位置或通过子帧号指示的起始位置。
本公开实施例所述一种上行免授权传输的配置方法为终端侧方法，执行主体为终端设备。
可选的，本公开实施例所述配置参数的参数包括：
所述起始位置，在本公开所有实施例应当理解为：通过系统帧和子帧的起始时间联合指示的起始时间或通过子帧的起始时间指示的起始时间；或者，通过系统帧和子帧的起始数值参数联合指示的数值位置或通过子帧指示的起始数值参数指示的数值位置标识。具体的，当通过系统帧和/或子帧的起始时间来指示时，所述起始位置表示起始时间位置；当通过系统帧和/或子帧的起始数值参数来指示时，所述起始位置表示起始数值参数位置。
所述子帧内部偏移量，在本公开所有实施例应当理解为：在子帧内部以时间为单位的时间偏移量，或者以时隙个数或符号个数为单位的数值偏移量。
所述传输周期，在本公开所有实施例应当理解为：以时间为单位的传输时周期，或者以子帧个数或时隙个数或符号个数为单位的传输周期。
以LTE系统为例。在LTE系统中，所述符号指OFDM符号。最大系统帧数是1024，即系统帧的编号范围为为0-1023，超过1023编号的系统帧又从0开始编号。单个系统帧内的子帧数为10，即一个系统帧包含10个子帧。一 个子帧内包含2个时隙，一个时隙包含7个OFDM符号。当然在NR系统中或其他系统中，由于子载波带宽不相同，子帧的配置以及子帧内的时隙数等会有所区别，本公开实施例对此不作限定。
本公开实施例S100所述当前配置参数，可以是终端设备通过自身当前的运行参数获取的，也可以是根据网络侧的指示获取的，也可以部分根据自身当前的运行参数获取，部分根据网络侧的指示获取。
首先，本公开实施例通过S100所述根据当前配置参数获取上行免授权传输的传输位置，包括：利用配置参数中的起始位置、子帧内部偏移量、传输周期等获取在上行免授权传输中的每个免授权数据的传输位置。
本公开实施例所述传输位置应当理解为时间位置或数值参数位置。如上所述，当以系统帧和/或子帧的起始时间、子帧内部偏移量的时间偏移量及以时间为单位的传输时周期计算时，所获取的是免授权数据的时间位置；当以系统帧和/或子帧的起始数值参数、子帧内部偏移量的时隙个数或符号个数为单位的数值偏移量及子帧个数或时隙个数或符号个数为单位的传输周期计算时，所获取的是免授权数据的数值参数位置。
其次，本公开实施例通过S200所述基于所述传输位置，获取对应的子帧时隙，包括：基于S100中获取的时间位置，根据系统帧、子帧及时隙等的时频资源配置，获取所述时间位置对应的子帧上的时隙；进一步，当系统在更短的时间粒度上，如在时隙内部配置更短的sTTI，如mini-slot等，则根据所述时间位置获取对应的mini-slot位置。或者
基于S100中获取的数值参数位置，获取所述数值参数位置对应的子帧上的时隙或mini-slot等。
最后，确定了传输的子帧时隙后，在所述子帧时隙如slot或mini-slot等上向网络侧发起上行免授权传输。
本公开实施例根据配置参数中的起始位置、子帧内部偏移量和传输周期等，获取上行免授权传输的传输位置，可灵活的适应当前系统中不同Numerology或不同时间粒度，支持NR系统中不同的Numerology和/或更短的调度时间粒度的配置，克服了相关技术的缺陷。
需要指出，本公开实施例所述当前配置参数指终端设备的当前配置参数。 终端设备通过当前配置参数进行上行免授权传输时，若收到网络侧指示的新的配置参数，则终端设备会执行步骤S100，将新的配置参数作为当前配置参数，重新获取上行免授权传输的传输位置，从而步骤S100和S200在通信过程中会交替执行。
在一个可选的实施例中，所述当前配置参数包括默认的配置参数和/或网络侧指示的配置参数。
应当理解，终端设备用于获取上行免授权传输的传输位置的配置参数包括以下几种情况中的任意一种：
(1)全部使用默认的配置参数。所述默认的配置参数是指终端设备根据自身的运行参数可以确定的配置参数，或预先设置的缺省的配置参数，或根据接收的下行信令推测的相应参数作为默认的配置参数。具体包括：
在网络侧通过RRC向终端设备配置上行免授权时，终端设备可以根据接收的RRC信令的系统帧号和子帧号作为默认的起始位置参数，或者以接收的RRC信令的第n个子帧subframe作为默认的子帧号。或者
终端设备设备根据接收的PDCCH信令的时频资源位置对应时隙个数或符号个数作为默认的子帧内部偏移量参数，或者直接将所述子帧内部偏移量参数设置为0。或者
终端设备设备根据当前运行时的传输周期的时间间隔作为默认传输周期参数。
以上仅列举了部分默认的配置参数的情况，实际的选取方法可以存在更多情况，可根据具体情况而定，本公开实施例不作具体限定。
(2)全部使用网络侧指示的配置参数。具体包括：
网络侧将所述配置参数中可以包含的所有参数通过RRC信令显式的指示给终端设备；或者
将所有参数通过PDCCH信令显式的指示给终端设备；或者
将部分参数通过RRC信令、另一部分参数通过PDCCH信令显式的指示给终端设备；或者
将部分参数通过RRC信令显式的指示给终端设备、另一部分参数通过PDCCH隐式的指示给终端设备；或者
将部分参数通过RRC信令隐式的指示给终端设备、另一部分参数通过PDCCH显式的指示给终端设备；或者
将所有参数通过PDCCH信令隐式的指示给终端设备。
以上几种情况，不论是RRC信令或PDCCH信令的显式或隐式的指示，终端设备用于获取传输位置的配置参数全部来自网络侧的指示。
在某些情况下，网络侧显式指示或隐式指示的配置参数与终端设备根据接收的下行信令推测的相应参数可能会相同。
(3)部分使用默认的配置参数，部分使用网络侧指示的配置参数。
如上述情况(2)所述，当网络侧通过RRC或PDCCH向终端设备指示了部分参数时，可以如上述情况(1)所述的方法选取部分默认参数，因而默认的配置参数可以包含所述配置参数的所有参数中的一种或多种，网络指示的配置参数也可以包含所述配置参数的所有参数中的一种或多种。
本公开实施例可以通过上述方法灵活的选择配置参数。网络侧如何通过RRC信令或PDCCH信令向终端设备指示配置参数，只需要双方共同约定规则，按照约定的规则去封装信令和解码信令即可，本公开实施例对此不作具体限定。
在一个可选的实施例中，S100所述获取上行免授权传输的传输位置，包括：
利用如下的计算式获取第N个上行免授权传输的传输位置T N：
T N＝(起始位置+子帧内部偏移量+传输周期*N)mod系统最大配置数；
其中，当所述起始位置通过系统帧号和子帧号联合指示时，所述系统最大配置数＝最大系统帧数*单个系统帧内的子帧数；当所述起始位置通过子帧号指示时，所述系统最大配置数＝单个系统帧内的子帧数。
本公开实施例具体给出了S100所述根据当前配置参数获取上行免授权传输的传输位置的方法，对于其中第N个上行免授权传输的传输位置T N的计算，N的取值为0、1、2、3等等，依此类推，具体根据数据传输的需求而定，通过上述计算式可以计算出上行免授权传输的第一次传输到最后一次传输的每一个传输时刻或传输位置，在所确定的传输时刻或传输位置依次发送上行免授权数据。上述计算式中的“mod”表示取模，是为了不超过最大系统帧数。
本公开实施例所述计算式中的起始位置，请参考前述实施例的相关描述，在此不再赘述。
所述计算式中的子帧内部偏移量包括以时间为单位的偏移量或以时隙个数或符号个数为单位的偏移量；
如前述实施例所述，所述子帧内部偏移量包括两种情况，即时间偏移量和数值偏移量；其中，以时隙个数或符号个数为单位的偏移量N_start_offset包括：以时隙的个数为单位偏移量或以符号的个数为单位偏移量。由于一个子帧内部包含若干时隙，一个时隙内部又包含若干符号(如NR系统中的符号为OFDM符号)，因此二者的粒度不一样，具体选用何种粒度根据通信系统的实际情况而定，本公开实施例对此不作具体限定。
所述计算式中的传输周期包括以时间为单位的传输周期或以子帧个数或时隙个数或符号个数为单位的传输周期。
如前述实施例所述，所述传输周期也包括两种情况，以时间表示的传输周期和以数值表示的传输周期；其中，以子帧个数或时隙个数或符号个数为单位的传输周期包括：以子帧个数为单位的传输周期、以时隙个数为单位的传输周期和以符号个数为单位的传输周期，它们的周期粒度越来越小。具体选用何种粒度根据通信系统的实际情况而定，本公开实施例对此不作具体限定。
在未来的通信系统中，如果包含比符号更小粒度的数值参数，只需要在本公开实施例的基础上进行扩展而不需要创造性的劳动，因此都应包含在本公开实施例的范围内。
本公开实施例所给出的时间偏移量、数值偏移量、以时间表示的传输周期和以数值表示的传输周期，在具体使用时需要互相配合。
在一个可选的实施例中，当选择所述子帧内部偏移量为以时间为单位的偏移量T_start_offset时，则选择所述传输周期为以时间为单位的传输周期T_interval，以获取上行免授权传输的传输时刻；
当选择所述子帧内部偏移量为以时隙个数或符号个数为单位的偏移量N_start_offset时，则选择所述传输周期为以子帧个数或时隙个数或符号个数为单位的传输周期N_interval，以获取上行免授权传输的传输位置；其中， 所述传输位置为子帧时隙的位置。
下面结合不同的数值参数Numerology和调度时间粒度参数对本公开实施例所述计算式进行展开描述。
在一个可选的实施例中，基于系统帧号、子帧号、以时间为单位的偏移量T_start_offset和以时间为单位的传输周期T_interval，所述计算式为第一计算式，所述第一计算式如下：
T N＝((subframe_per_SFN*T_SFN_start+T_subframe_start)+T_start_offset+N*T_interval)mod max_SFN*subframe_per_SFN；
其中，T N为上行免授权传输的传输时刻，T_SFN_start为系统帧起始时间，T_subframe_start为子帧起始时间，max_SFN为最大系统帧数，subframe_per_SFN为单个系统帧内的子帧数。
本公开实施例中，终端设备根据当前配置参数的系统帧号、子帧号、以时间为单位的偏移量T_start_offset和以时间为单位的传输周期T_interval，利用第一计算式获取上行免授权传输的传输时刻。由于同时配置了系统帧号和子帧号，因此本公开实施例所述第一计算式中的取模的基数为最大系统帧数*单个系统帧内的子帧数。
具体的，在5G NR系统中，max_SFN＝1024，subframe_per_SFN＝10，则所述第一计算式可表示为：
T N＝((10*T_SFN_start+T_subframe_start)+T_start_offset+N*T_interval)mod 10240。
图2为本公开实施例60kHz子载波间隔下的子帧示意图。如图2所示的一个具体实例中，当所述子载波间隔为60kHz时，1个subframe的长度为1毫秒(ms)，1个slot的长度为0.25ms，相当于1个subframe包含4个60kHz的slot。给定T_start_offset＝0.25,即距离subframe的起始位置偏移0.25ms；给定T_interval＝0.5，即在子帧内部的传输周期为0.5ms。给定T_SFN_start＝0，T_subframe_start＝1，则所述第一计算式可表示为：
T N＝((10*0+1)+0.25+N*0.5)mod 10240＝1+0.25+N*0.5。
当N＝0时，T N＝1.25，对应图2中subframe#1的slot#1；
当N＝1时，T N＝1.75，对应图2中subframe#1的slot#3；
当N＝2时，T N＝2.25，对应图2中subframe#2的slot#1；
以此类推，不再赘述。
在一个可选的实施例中，基于子帧号、以时间为单位的偏移量T_start_offset和以时间为单位的传输周期T_interval，所述计算式为第二计算式，所述第二计算式如下：
T N＝(T_subframe_start+T_start_offset+N*T_interval)mod subframe_per_SFN；
其中，T N为上行免授权传输的传输时刻，T_subframe_start为子帧起始时间，subframe_per_SFN为单个系统帧内的子帧数。
相比于前一个实施例，本实施例中终端设备的配置参数的起始位置通过子帧号来指示，仍然是时间偏移量和以时间为单位的传输周期，取模的基数为单个系统帧内的子帧数。
具体的，在5G NR系统中，subframe_per_SFN＝10，则所述第二计算式可表示为：
T N＝(T_subframe_start+T_start_offset+N*T_interval)mod 10；
通过所述第二计算式获取的传输时刻是相对于当前系统帧的偏移时刻，当N取不同值时，若计算的时间超过10个子帧的范围，则超出的时间为下一个系统帧的子帧的时间，以此类推；其计算方法与前一个实施例相同，在此不再重复举例。
在一个可选的实施例中，基于系统帧号、子帧号、以时隙个数或符号个数为单位的偏移量N_start_offset和以子帧个数或时隙个数或符号个数为单位的传输周期N_interval，所述计算式为第三计算式或第四计算式；
所述第三计算式如下：
T N＝N_slot_symbol_per_subframe*(((subframe_per_SFN*N_SFN_start+N_subframe_start)+N_start_offset/N_slot_symbol_per_subframe+N*N_interval)mod max_SFN*subframe_per_SFN)；
所述第三计算式的适用范围为：传输周期N_interval以子帧为单位，且传输周期大于或等于1个子帧，比如传输周期为1个子帧、2个子帧或3个 子帧等等，不一一列举。
所述第四计算式如下：
T N＝N_slot_symbol_per_subframe*(((subframe_per_SFN*N_SFN_start+N_subframe_start)+(N_start_offset+N*N_interval)/N_slot_symbol_per_subframe)mod max_SFN*subframe_per_SFN)；
所述第四计算式的适用范围为：传输周期N_interval以时隙或符号为单位，此时传输周期小于1个子帧，比如传输周期为1个slot、2个slot、3个slot、1个symbol、2个symbol或3个symbol等等，不一一列举。
其中，T N为上行免授权传输的传输位置，N_SFN_start为系统帧起始位置，N_subframe_start为子帧起始位置，max_SFN为最大系统帧数，subframe_per_SFN为单个系统帧内的子帧数，N_slot_symbol_per_subframe为单个子帧内的时隙个数或符号个数。
本公开实施例中，终端设备根据当前配置参数的系统帧号、子帧号、以时隙个数或符号个数为单位的偏移量N_start_offset和以子帧个数或时隙个数或符号个数为单位的传输周期N_interval，利用第三计算式或第四计算式是获取上行免授权传输的传输时刻。所述第三计算式或第四计算式中的取模的基数为最大系统帧数*单个系统帧内的子帧数。
具体的，在5G NR系统中，max_SFN＝1024，subframe_per_SFN＝10，则所述第三计算式可表示为：
T N＝N_slot_symbol_per_subframe*(((10*N_SFN_start+N_subframe_start)+N_start_offset/N_slot_symbol_per_subframe+N*N_interval)mod 10240)；
所述第四计算式可表示为：
T N＝N_slot_symbol_per_subframe*(((10*N_SFN_start+N_subframe_start)+(N_start_offset+N*N_interval)/N_slot_symbol_per_subframe)mod 10240)；
图3为本公开实施例15kHz子载波间隔下的子帧示意图。如图3所示的一个具体实例中，当所述子载波间隔为15kHz时，1个slot包含7个OFDM符号，此时1个Subframe包含2个slot。采用mini-slot(mSlot)时间粒 度，在1个subframe内，mini-slot#1、mini-slot#2、mini-slot#3和mini-slot#4的符号长度为2个OFDM符号，mini-slot#0和mini-slot#5的符号长度为3个OFDM符号。每个subframe内包含的mini-slot数为6。给定N_SFN_start＝0，N_subframe_start＝1，N_start_offset＝1，即距离subframe的起始位置偏移1个mSlot；N_interval＝2，即在子帧内部的传输间隔为2个mSlot。
由于上述实例中的传输周期N_interval小于1个子帧，因而适用第四计算式，此情况下所述第四计算式可表示为：
T N＝6*(((10*0+1)+(1+N*2)/6)mod 10240)＝7+N*2；
当N＝0时，T N＝7，对应图3中subframe#1的mini-slot#1；
当N＝1时，T N＝9，对应图3中subframe#1的mini-slot#3；
当N＝2时，T N＝11，对应图3中subframe#1的mini-slot#5；
以此类推，不再赘述。
在一个可选的实施例中，基于子帧号、以时隙个数或符号个数为单位的偏移量N_start_offset和以子帧个数或时隙个数或符号个数为单位的传输周期N_interval，所述计算式为第五计算式或第六计算式；
所述第五计算式如下：
T N＝N_slot_symbol_per_subframe*((N_subframe_start+N_start_offset/N_slot_symbol_per_subframe+N*N_interval)mod subframe_per_SFN)；
所述第五计算式的适用范围为：传输周期N_interval以子帧为单位，且传输周期大于或等于1个子帧，同所述第三计算式的使用范围。
所述第六计算式如下：
T N＝N_slot_symbol_per_subframe*((N_subframe_start+(N_start_offset+N*N_interval)/N_slot_symbol_per_subframe)mod subframe_per_SFN)；
所述第六计算式的适用范围为：传输周期N_interval以时隙或符号为单位，同所述第四计算式的适用范围。
其中，T N为上行免授权传输的传输位置，N_subframe_start为子帧起始位置，max_SFN为最大系统帧数，subframe_per_SFN为单个系统帧内的子帧数，N_slot_symbol_per_subframe为单个子帧内的时隙个数或符号个数。
相比于前一个实施例，本实施例中终端设备的配置参数的起始位置通过子帧号来指示，仍然是数值偏移量和以数值为单位的传输周期，取模的基数为单个系统帧内的子帧数。
具体的，在5G NR系统中，subframe_per_SFN＝10，则所述第五计算式可表示为：
T N＝N_slot_symbol_per_subframe*((N_subframe_start+N_start_offset/N_slot_symbol_per_subframe+N*N_interval)mod 10)
所述第六计算式可表示为：
T N＝N_slot_symbol_per_subframe*((N_subframe_start+(N_start_offset+N*N_interval)/N_slot_symbol_per_subframe)mod 10)；
通过所述第五计算式或所述第六计算式获取的传输位置是相对于当前系统帧的偏移位置，当N取不同值时，若计算的位置超过10个子帧的范围，则超出的时间为下一个系统帧的子帧的位置，以此类推；其计算方法与前一个实施例相同，在此不再重复举例。
本公开实施例基于以时间为单位的偏移量T_start_offset和以时间为单位的传输周期T_interval，利用第一计算式或第二计算式获取上行免授权传输的传输时刻，且所述子帧时隙采用不等长的mini-slot配置时，所计算的传输时刻可能会与mini-slot的起始时间不对齐，则本公开实施例提供如下的几种确定最终传输时刻的方法。需要说明，本公开所有实施例中所述min-slot可理解为由一个或多个符号组成的时间粒度，不同的min-slot可由不同数目的符号组成。
所述几种确定最终传输时刻的方法，包括：
在一个可选的实施例中，当所述子帧时隙采用不等长的mini-slot配置时，在所述计算式确定的传输时刻对应的mini-slot上向网络侧发起上行免授权传输，如图4所示。可进一步理解为，在所述计算式确定的传输时刻对 应的mini-slot的起始时刻发送上行免授权数据。
在另一个可选的实施例中，当所述子帧时隙采用不等长的mini-slot配置时，在所述计算式确定的传输时刻对应的mini-slot内、在所述传输时刻向网络侧发送上行免授权参考信号，且在所述对应的mini-slot的剩余资源上向网络侧发送上行免授权数据，如图5所示。可进一步理解为，在计算得到的传输时刻发送上行免授权参考信号，在所述传输时刻对应的mini-slot的、发送了参考信号的剩余资源上发送上行免授权数据。所述剩余资源包括时域和频域资源。
在另一个可选的实施例中，当所述子帧时隙采用不等长的mini-slot配置时，在所述计算式确定的传输时刻对应的mini-slot后的第k个mini-slot上向网络侧发起上行免授权传输；或者，在所述计算式确定的传输时刻对应的mini-slot的符号后的第k个符号上向网络侧发起上行免授权传输；其中k为整数，k大于或等于1，如图6所示。
可进一步理解为，当k＝1时，在计算得到的传输时刻对应的mini-slot之后的第1个mini-slot的起始时刻发送上行免授权数据；当k＝2时，在计算得到的传输时刻对应的mini-slot之后的第2个mini-slot的起始时刻发送上行免授权数据，以此类推，不一一列举。或者，可进一步理解为，当k＝1时，在计算得到的传输时刻对应的mini-slot中的符号之后的第1个符号的起始时刻发送上行免授权数据；当k＝2时，在计算得到的传输时刻对应的mini-slot中的符号之后的第2个符号的起始时刻发送上行免授权数据，以此类推，不一一列举。此情况下的参考信号可在计算得到的传输时刻对应的mini-slot的起始时刻进行传输，或者在所述对应的mini-slot之前的适当的时刻传输，可根据实际情况约定，本公开实施例对此不作具体限定。
需要指出，上述当所述子帧时隙采用不等长的mini-slot配置时，所计算的传输时刻可能会与mini-slot的起始时间不对齐的情况，在以数值参数进行计算时不会出现，即利用第三计算式、第四计算式、第五计算式、或第六计算式获取上行免授权传输的传输位置时不会出现不对齐情况，因为本来就是以时隙个数或符号个数计算的。
