本申请主张在2020年6月2日在中国提交的中国专利申请号No.202010490094.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，特别涉及一种定时提前补偿指示、确定方法、设备、装置及介质。
背景技术
为了实现终端与基站之间的上行同步,终端在发送上行数据时，需作一个定时提前，假设定时提前量为TA-adjust(TA调整，TA：定时提前，Timing Advance)，该参数根据基站指示确定。以相关技术中的5G系统举例，TA-adjust＝(N TA+N TA,offset)·T c，其中T c为用户设备(User Equipment，UE)定时调整时间单元，N TA,offset由UE侧发送上行数据的频带位置和双工方式配置确定，一种现有的方式是，具体参数取值参照3GPP TS 38.133 V16.0.0表格7.1.2-2确定，例如，采用时分复用(Time Division Duplex，TDD)模式，频带为低频频率范围(Frequency range，FR)1且存在长期演进(Long Term Evolution，NR-LTE)共存，则取值为0；采用TDD或者频分双工(Frequency Division Duplex，FDD)模式，频带低频FR1且不存在NR-LTE共存，则取值为25600，N TA则依据UE接收到的定时提前指示确定。如果UE发送上行数据是在传统4步随机接入过程中，在接收到随机接入响应Msg(消息)2之后发送的Msg3，则N TA＝T A·16·64/2 μ，其中T A为Msg2中与该终端发送的前导序列有关的随机接入响应(Random Access Response，RAR)指示的定时提前量，参数μ为与上行发送的子载波间隔相关的一个参数，例如，如果子载波间隔为15KHz，则μ＝0。如果UE发送上行数据，并且最新接收到了由MAC CE(媒体接入控制控制单元；MAC：媒体接入控制，Media Access Control；CE：控制单元，Control Element)指示的上行定时提前命令，则 N TA_new＝N TA_old+(T A-31)·16·64/2 μ，其中T A为定时提前命令中指示的定时提前量。
根据相关技术中的系统，终端在随机接入过程中及无线资源控制(Radio Resource Control，RRC)连接状态获取定时提前指示，在发送随机接入信号(生成随机接入前导序列)时，定时提前N TA为零，即不作定时提前预补偿。相关技术中的系统中定时提前指示最大范围为2ms，对应了基站支持最大覆盖范围。
相关技术的不足在于，相关技术中的定时提前处理方式不适应范围为2ms以上的通信环境。

附图说明
此处所说明的附图用来提供对本公开的进一步理解，构成本公开的一部分，本公开的示意性实施例及其说明用于解释本公开，并不构成对本公开的不当限定。在附图中：

具体实施方式
发明人在发明过程中注意到：
相关技术中的定时提前处理方式不适应终端与基站之间远距离通信场景，例如非地面通信场景，需要上行定时提前范围远超过相关技术中的系统可指示范围。为了实现上行发送信号可以在基站侧得到正确检测，终端需要在发送上行信号，包括随机接入信号等作所述基站定时提前指示N TA以及N TA,offset之外的定时提前预补偿。所述定时提前预补偿叠加上相关技术中的系统的N TA以及N TA,offset扩大终端上行定时提前范围，相应的支持更远距离的通信需求。
对于终端上行信号作定时提前预补偿，可以根据系统指示作定时提前预补偿，即基站给终端指示或者协议约定一个或多个一个参考位置的定时提前信息，终端将一个参考位置的定时提前信息作为定时提前补偿信息。相应的，如果终端在多个参考位置的定时提前信息中选择一个定时提前补偿信息，相关技术中的系统中基站无法获知终端选择哪个作为定时提前补偿，进一步无法获知终端完整的上行定时提前信息。
当基站无法获知终端完整的上行定时提前信息时，则会影响基站侧上行资源调度。因为基站需要参考终端上行定时提前信息，确保终端接收到调度上行传输的下行信号后，有足够的处理时延处理被调度的上行信号。如果基站没有获取终端上行定时提前信息，则导致终端没有足够的处理时延发送调度的上行信号导致出错，或者基站参考最大传播距离进行上行调度，给终端指示一个最大的上行信号定时，导致上行信号传输效率降低。
基于此，本公开实施例提供的技术方案，在于解决基站在给终端指示或者协议约定多个上行定时提前补偿下，终端向基站上报选择一个上行定时提前补偿，使得基站可以获知终端完整上行定时补偿信息，确保上行调度正确以及提高上行传输效率。在方案中，终端在随机接入过程中通过隐性指示的方式向基站上报终端上行定时提前补偿信息。
下面结合附图对本公开的具体实施方式进行说明。
在说明过程中，将分别从UE与基站侧的实施进行说明，然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当UE与基站分开实施时，其也各自解决UE侧、基站侧的问题，而二者结合使用时，会获得更好的技术效果。
由于基站侧与UE侧的实施具有一定的对应关系，因此说明过程中将主要以UE侧为主进行说明，本领域技术人员根据UE侧的实施进行相适应的调整即可确定基站侧的实施。
在实施中，主要以UE为移动通信终端、基站或者接入点AP为接入设备为例进行说明，这是因为其比较典型，且是正在采用以及将要采用的技术，所以这里以其为例；但是，只要涉及定时提前补偿的通信设备也是可以采用本公开实施例提供的技术方案的，本公开实施例中描述的终端，是指可以支持陆地移动通信系统的通信协议的终端侧产品，特制通信的调制解调器模块(Wireless Modem)，其可以被手机、平板电脑、数据卡等各种类型的终端形态集成从而完成通信功能，UE、基站或者接入点AP仅用于教导本领域技术人员具体如何实施本公开，但不意味仅能在UE、基站或者接入点AP使用，实施过程中可以结合实践需要进行相适应的改进即可。

例如，当N＝2，当UE确定定时提前补偿为Pre_TA1时，其采用前导分 组中的第1组中的前导序列发起随机接入，当UE确定定时提前补偿为Pre_TA2时，其采用前导分组中的第2组中的前导序列发起随机接入。
具体实施中，当前导序列分组时，可以进一步包括：
若因触发随机接入需要发送的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)负载超过设定大小更换前导序列所在分组，与所述定时提前补偿对应的前导序列所在分组发生冲突时，调整所述定时提前补偿对应的前导序列所在分组。
可选的，当随机接入的前导序列已有分组，例如分为A组和B组，当触发随机接入需要发送的PUSCH负载超过设定大小时，选择B组中的前导序列发起随机接入。在该方式下，所述不同定时提前补偿对应的前导分组将在已有随机接入前导序列分组中实现，以避免前导序列选择冲突。具体的例如，假设已有随机接入前导序列分组为A组和B组，在所述A组和B组前导序列分别进一步分为N组，分别对应N个上行定时提前补偿取值，如下表2所示。
表2：

例如，当N＝2，当UE确定选择前导序列分组A中的前导序列时，如果定时提前补偿为Pre_TA1时，其采用前导分组中的第A1组中的前导序列发起随机接入，如果定时提前补偿为Pre_TA2时，其采用前导分组中的第A2组中的前导序列发起随机接入。
2、所述第一配置信息中包含分组的随机接入机会，一组随机接入机会对应一个上行定时提前补偿取值。
第一配置信息中包含N(N为大于等于1的整数)组随机接入机会(RO)，其中一组RO对应一个上行定时提前补偿取值，如下表3所示：
表3：
等级 上行定时提前补偿 RO分组
1 Pre_TA 1 第1组
2 Pre_TA 2 第2组
3 Pre_TA 3 第3组
… … …
N Pre_TA N 第N组
所述RO为用于承载前导序列时频资源。当N＝2，当UE确定定时提前补偿为Pre_TA1时，其采用RO分组中的第1组中的前导序列发起随机接入，当UE确定定时提前补偿为Pre_TA2时，其采用RO分组中的第2组中的前导序列发起随机接入。
具体实施中，随机接入机会是以时域配置索引来标识随机接入机会在时域对应占用的时隙位置、一个时隙内的随机接入机会占用的符号位置、或一个随机接入机会在时域占用的符号长度的；和/或，
随机接入机会是以频域配置索引来标识随机接入机会在频域对应占用的频域位置。
具体的，N个RO分组的具体实现方式可以为配置N个随机接入机会的时域配置索引(例如prach-ConfigurationIndex_n,n＝1,2,…,N)，其中prach-ConfigurationIndex_n(PRACH-配置索引_n)对应第n个定时补偿提前取值。随机接入机会的时域配置索引，可以确定随机接入机会在时域对应占用的时隙位置、一个时隙内的随机接入机会占用的符号位置、一个随机接入机会在时域占用的符号长度，相应的一个随机接入时域配置索引在时域可以对应一个或多个RO资源。
N个RO分组的具体实现方式可以为配置N个随机接入机会的频域配置指示(例如Msg1-FDM_n,n＝1,2,…,N)，其中Msg1-FDM_n对应第n个定时补偿提前取值。所述随机接入机会的频域配置指示，可以确定随机接入机会 在频域对应占用的频域位置，相应的一个随机接入频域配置指示在频域可以对应一个或多个RO资源。
具体实施中，随机接入机会是按随机接入周期对时域和/或频域来配置随机接入机会的。
具体的，N个RO分组的具体实现方式可以为，假设根据随机接入配置信息，一个随机接入周期中包含Z个(Z为大于等于1的整数)RO，假设RO资源在一个随机接入周期中对应P个时域RO索引，对应Q个频域RO索引，则Z＝P·Q，将Z个RO资源分为N组，所以，以标准T38.321为例，一个随机接入周期可以为标准(38.321)中定义的一个或多个随机接入配置周期(PRACH configuration period)、或者一个或多个随机接入机会关联周期(PRACH occasion association period)、或者一个或多个随机接入机会关联图样周期(PRACH occasion association pattern period)。
具体实施中，随机接入机会是按组来配置时域和/或频域资源的。
具体的，N个RO分组的具体实现方式可以为将配置的RO资源在时域上分为N组。
例如配置的RO资源在时域上索引为T1T2T3T4，频域索引为F1F2，对应了8个RO资源索引分别为(T1F1)、(T1F2)、(T2F1)、(T2F2)、(T3F1)、(T3F2)、(T4F1)、(T4F2)。将RO在时域上分为两组，如将索引T1T2分为一组、T3T4分为一组，对应的RO分组第一组为(T1F1)、(T1F2)、(T2F1)、(T2F2)，第二组为(T3F1)、(T3F2)、(T4F1)、(T4F2)。
N个RO分组的具体实现方式可以为将配置的RO资源在频域上分为N组。例如配置的RO资源在时域上索引为T1T2，频域索引为F1F2F3F4，对应了8个RO资源索引分别为(T1F1)、(T1F2)、(T1F3)、(T1F4)、(T2F1)、(T2F2)、(T2F3)、(T2F4)。将RO在频域上分为两组，如将索引F1F2分为一组、F3F4分为一组，对应的RO分组第一组为(T1F1)、(T1F2)、(T1F3)、(T1F4)，第二组为(T2F1)、(T2F2)、(T2F3)、(T2F4)。
具体实施中，所述第一配置信息中包含分组的随机接入机会，一组随机接入机会对应一种随机接入类型的一个上行定时提前补偿取值。
具体的，当随机接入配置了两种随机接入类型，如4-step RACH(4步随 机接入)和2-step RACH(2步随机接入)，如果4-step RACH和2-step RACH采用不同的RO配置，如采用不同的随机接入时域配置索引。在该特征下，所述不同定时提前补偿对应的RO分组将在随机接入类型对应的RO配置中实现，以使不同随机接入类型的RO配置下基于RO分组对应不同的上行定时提前补偿。具体的，例如，假设已有4-step RACH RO分组和2-step RACH RO分组，分别对应N个上行定时提前补偿取值，如下表4所示.
表4：
Figure PCTCN2020133268-appb-000002
例如，当N＝2，当UE确定4-step RACH发起随机接入时，如果定时提前补偿为Pre_TA1时，其采用4-step RACH RO分组的第A1组中的RO承载前导序列发起随机接入，如果定时提前补偿为Pre_TA2时，其采用4-step RACH RO分组的第A2组中的RO承载前导序列发起随机接入。
3、所述第一配置信息中包含分组的同步广播块，一组同步广播块对应一个上行定时提前补偿取值。
第一配置信息中包含N(N为大于等于1的整数)组同步广播块(Synchronization Signal Block，同步广播块)，其中一组SSB对应一个上行定时提前补偿取值，如下表5所示：
表5：
等级 上行定时提前补偿 SSB分组
1 Pre_TA 1 第1组
2 Pre_TA 2 第2组
3 Pre_TA 3 第3组
… … …
N Pre_TA N 第N组
所述一个SSB包含主同步信号、广播信号、辅同步信号，对应了一个SSB时频资源或者一个波束。例如当N＝2，当UE确定定时提前补偿为Pre_TA1时，其采用SSB分组中的第1组中的SSB关联的随机接入资源发起随机接入，当UE确定定时提前补偿为Pre_TA2时，其采用SSB分组中的第2组中的SSB关联的随机接入资源发起随机接入。
具体实施中，还可以进一步包括：
如果不同定时提前补偿对应的前导序列标识出现冲突，或者如果不同定时提前补偿对应的RO之间出现位置冲突，或者如果不同定时提前补偿对应的SSB索引出现冲突，则冲突区域的前导序列标识或者RO或者SSB索引对应的定时提前补偿为该RO对应的定时提前补偿中的最小值或者最大值。
具体的，终端不希望不同定时提前补偿对应的前导序列标识或者RO之间或者SSB索引出现位置冲突。如果不同定时提前补偿对应的前导序列标识出现冲突，或者如果不同定时提前补偿对应的RO之间出现位置冲突，或者如果不同定时提前补偿对应的SSB索引出现冲突，则冲突区域的前导序列标识或者RO或者SSB索引对应的定时提前补偿为该RO对应的定时提前补偿中的最小值或者最大值。
图3为冲突示意图，如图3所示，定时提前补偿Pre_TA 1和Pre_TA2对应的前导序列标识或者RO之间或者SSB发生冲突，则冲突区域的前导序列标识或者RO之间或者SSB对应的定时提前补偿为Pre_TA 1和Pre_TA2之间的较小值或者较大值。
实施中，所述第一配置信息是基站向终端发送的，和/或，是根据协议约定写入UE的。
具体的，终端获取第一配置信息的方式可以为基站向终端发送第一配置信息，或者根据协议约定设备写入第一配置信息，或者以上方式联合的方式获取。
实施中，所述定时提前补偿是对以下上行发送信号之一或者其组合进行 定时提前补偿：
前导序列、PUCCH、PUSCH。
具体的，上行定时提前补偿包括对前导序列、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、PUSCH等在内的上行发送信号作定时提前补偿。
在实际应用中，上行定时提前补偿可以在终端侧实现或者在基站侧实现。例如假设上行定时提前补偿为Pre_TA，在终端侧实现则为终端发送上行信号时相比下行定时总的定时提前量为Pre_TA、N TA(基站指示定时提前量)以及N TA,offset(如果有)之和，基站侧按照原上行定时接收上行信号。在基站侧实现则为终端发送上行信号为N TA(基站指示定时提前量)以及N TA,offset(如果有)之和，基站侧上行定时相比下行定时偏移一个Pre_TA接收上行定时补偿为Pre_TA对应的上行信号。
二、终端确定发送上行信号所需的定时提前补偿，根据第一配置信息，选择所述定时提前补偿对应的前导序列及承载前导序列的时频资源发送前导序列。
具体的，终端确定发送上行信号所需的定时提前补偿，根据第一配置信息，选择所述定时提前补偿对应的前导序列及承载前导序列的时频资源发送前导序列。
终端确定发送上行信号所需的定时提前补偿，相应方式可以为根据终端估计的与基站之间或者参考位置之间的传播时延确定，或者测量的SSB等方式确定。例如确定的所需的定时提前补偿量为Pre_TA_calulcated,则在所述N个定时提前补偿中选择与Pre_TA_calulcated大小最接近的一个，或者小于Pre_TA_calulcated中的定时提前补偿中与Pre_TA_calulcated大小最接近的一个作为定时提前补偿。又例如，终端测量SSB，选择其中满足随机接入条件的一个SSB，将该SSB对应的定时提前补偿作为定时提前补偿。
终端进一步结合第一配置信息选择随机接入对应的RO及前导序列发送随机接入信号。
如果第一配置信息包含前导序列分组，当UE确定其选择的定时提前补偿所在前导序列分组，采用该前导序列分组中的前导序列发送随机接入信号。
如果第一配置信息包含RO分组，当UE确定其选择的定时提前补偿所在RO分组，采用该RO承载前导序列发送随机接入信号。
如果第一配置信息包含SSB分组，当UE确定其选择的定时提前补偿所在SSB分组，采用该SSB关联的RO及前导序列发送随机接入信号。

如果第一配置信息包含SSB，如基站通过前导序列检测识别到对应的SSB索引在所述SSB分组中的第n(n＝1,2,…,N)组，则对应的终端的定时提前补偿为Pre_TA n。
实施中，还可以进一步包括：
基站结合给终端的定时提前指示获取终端完整的定时提前信息，并根据该定时提前信息为终端调度上行传输资源。
具体的，基站识别终端定时提前补偿信息之后，可以结合给终端的定时提前指示获取终端完整的定时提前信息，根据该定时提前信息为终端调度上行传输资源。
