图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(evolved Node B，eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmission Reception Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。下面结 合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的上行传输的方法200的流程示意图，该方法200可以但不限于由终端执行，具体可由安装于终端中的硬件和/或软件执行。本实施例中，所述方法至少可以包括如下步骤。
S210，所述终端基于目标方式和/或TA调整颗粒度调整目标上行传输的时间。
其中，所述目标方式包括以下方式1、方式2中的至少一项。
方式1：根据所述第一目标定时提前命令(Timing Advance Command，TAC)调整所述第一目标对象对应的目标上行传输的时间。
方式2：根据下行时间差值以及所述第一目标TAC调整第二目标对象对应的目标上行传输的时间，所述下行时间差是第一下行传输时间与第二下行传输时间之间的差值，所述第一下行传输时间是终端接收到所述第一目标对象对应的下行传输的时间，所述第二下行传输时间是终端接收到所述第二目标对象对应的下行传输的时间。
前述方式1和方式2中，所述第一目标TAC与所述第一目标对象关联，对此可以理解为：所述第一目标TAC是用于通知终端上行传输提前发送相应的时间量，如定时提前量(Timing Advance，TA)。例如，所述第一目标TAC是用于通知所述终端与所述第一目标对象对应的TA，使得所述终端可基于该TA调整所述第一目标对象对应的上行传输时间，或，所述终端根据所述第一目标TAC所通知的TA调整除所述第一目标对象之外的其他目标对象对应的上行传输的时间。
当然，在一种实现方式中，所述第一目标对象可以是但不限于SRS资源 集、SRS资源、传输配置指示(Transmission Configuration Indicator，TCI)状态、TCI状态池、天线分组、面板(panel)、TRP、资源池索引(CoresetPoolIndex)，TAG,TAG索引等。
基于此，对于存在多个目标对象的场景，所述终端基于所述目标方式进行目标上行传输时间调整的过程可以如下。
在所述目标方式包括方式1时，所述终端可以根据与目标对象一一对应的目标TAC进行上行传输时间的调整，如前述的根据第一目标TAC调整所述第一目标对象对应的目标上行传输的时间，由此，对于不同的目标对象能够采用不同的TA进行上行传输时间的调整，从而能够确保上行传输时间调整的精确、高效，进而确保各目标对象对应的上行传输时间满足用户间正交的关系，避免带来用户间干扰，达到提高上行传输性能的目的。尤其在目标对象为TRP时，还能达到通过多TRP传输提升吞吐量的目的。
在所述目标方式包括方式1和方式2时，所述终端可以根据接收到的第一目标TAC对与其关联的第一目标对象对应的目标上行传输进行上行传输的时间调整，而对于多个目标对象中除第一目标对象之外的其他目标对象，如第二目标对象，可以根据第一目标TAC和上行时间差实现对其对应的上行传输时间的调整，由此，相比于前述方式1，本实现方式能够在只有一个目标TAC的情况下，实现对多个目标对象对应的上行传输时间的精确、高效调整，且终端实现简单。
可以理解，在所述目标方式仅包括方式2时，其实现过程可参照前述目标方式包括方式1和方式2时的相关描述，为避免重复，在此不再赘述。
值得注意的是，相比于相关技术，本实施例中基于前述的方式1和/或方式2所实现的上行传输时间的调整过程，是采用与目标对象一一关联的(或对应的)TA，即不同的目标对象利用不同的TA进行上行传输时间的调整，由此，能够确保上行传输时间调整的精确、高效，进而确保各目标对象对应 的上行传输时间满足用户间正交的关系，使得不同用户传输到达一个对象(如TRP等)的上行传输时间差不超出循环前缀(Cyclic Prefix，CP)，避免带来用户间干扰，达到提高上行传输性能的目的。
可以理解，前述的第一目标TAC的获取方式可以有多种，例如，所述终端可以通过接收媒体接入控制控制单元(Medium Access Control Control Element，MAC CE)的方式获取，该MAC CE中至少包括第一目标定时提前命令(Timing Advance Command，TAC)，也可以通过协议约定的方式获取，在此不做限制。
一种实现方式中，所述终端在通过MAC CE获取第一目标TAC时，所述MAC CE中还可携带有与所述第一目标TAC关联的第一目标对象的标识。当然，如果第一目标TAC包括第一TAC和第二TAC，那么，所述MAC CE中还可携带与第一TAC关联的第一对象的标识，以及与第二TAC关联的第二对象的标识等，在此不做限制。
需要注意的是，如果所述MAC CE中仅包括第一目标TAC，那么，与所述第一目标TAC与第一目标对象之间的关联关系可以由协议约定、高层配置等方式实现，在此不做限制。
进一步，所述TA调整颗粒度可以理解为所述终端进行两次TA调整的最小间隔，以用于避免频繁调整带来的终端功耗高、信令开销大的问题，同时还可以降低终端实现的复杂度。
可选的，在本实施例中，所述TA调整颗粒度可以由所述终端自主确定或所述终端根据接收到的第三无线资源控制(Radio Resource Control，RRC)信令确定，所述第三RRC信令中配置有TA调整颗粒度。当然，如果所述TA调整颗粒度是由所述终端自主确定，所述终端可以上报所述TA调整颗粒给 所述网络侧设备，以确保所述终端和所述网络侧设备对所述TA调整颗粒度理解的一致性。
另外，所述TA调整颗粒度的大小可以根据通信需求进行定义，例如，对于不同的子载波间隔(Subcarrier Spacing，SCS)的配置，可以定义不同长度的调整颗粒度，如所述TA调整颗粒度可以为0.5个时隙(Slot)、1个时隙、2个时隙、3个时隙或4个时隙等。当然，除了以时隙作为时间单位之外，所述TA调整颗粒度也可以以帧、子帧、符号等作为时间单位，在此不做限制。
在此情况下，对于前述的目标方式和TA调整颗粒度，所述终端可以根据协议约定、高层配置或网络侧配置等方式，确定是基于目标方式还是基于TA调整颗粒度还是基于目标方式TA调整颗粒度实现上行传输时间的调整，本实施例在此不做限制。
本实施例中，终端根据目标方式和/或TA调整颗粒度进行目标上行传输的时间的调整，其中，所述目标方式包括根据所述第一目标TAC调整所述第一目标对象对应的目标上行传输的时间，和/或，根据下行时间差值以及所述第一目标TAC调整第二目标对象对应的目标上行传输的时间，由此，一方面，对于不同的目标对象能够采用不同的TA进行上行传输时间的调整，从而能够确保上行传输时间调整的精确、高效，进而确保各目标对象对应的上行传输时间满足用户间正交的关系，避免带来用户间干扰，达到提高上行传输性能的目的；另一方面，基于TA调整颗粒度进行目标上行传输的时间的调整，能够避免频繁调整带来的终端功耗高、信令开销大的问题，同时还可以降低终端实现的复杂度。
如图3所示，为本申请一示例性实施例提供的上行传输的方法300的流程示意图，该方法300可以但不限于由终端执行，具体可由安装于终端中的 硬件和/或软件执行。本实施例中，所述方法至少可以包括如下步骤。
S310，所述终端上报第一信息。
其中，所述第一信息包括以下(11)-(13)中的至少一项。
(11)终端能力信息，所述终端能力信息包括所述终端支持一个TA对应的TA调整模式，和/或所述终端支持多个TA对应的TA调整模式。本实施例中，所述终端支持一个TA对应的TA调整模式可以理解为对于多个目标对象采用同一个TA进行上行传输时间的调整；所述终端支持多个TA对应的TA调整模式可以理解为：对于多个目标对象，不同的目标对象采用不同的TA进行上行传输时间的调整。
(12)终端推荐的TA个数，所述TA个数是所述终端根据下行测量确定。
(13)所述下行时间差，所述下行时间差是所述终端根据下行测量确定。
其中，前述(12)和(13)用于辅助网络侧设备指示是否使能多个TA的TA调整模式。例如，如果所述终端推荐的TA个数为2，那么，所述网络侧指示使能多个TA的TA调整模式，反之则不使能。又例如，如果所述下行时间差大于预定值，那么，所述网络侧指示使能多个TA的TA调整模式，反之则不使能，由此，能够提高TA调整过程的灵活性。
基于此，可以理解后续的S320的实现是在所述终端支持多个TA的TA调整模式、且是在网络侧设备指示使能多个TA的TA调整模式的情况下实现，具体不再赘述。
S320，所述终端基于目标方式和/或TA调整颗粒度调整目标上行传输的时间。
其中，所述目标方式包括以下方式1、方式2中的至少一项。
方式1：根据所述第一目标TAC调整所述第一目标对象对应的目标上行 传输的时间。
方式2：根据下行时间差值以及所述第一目标TAC调整第二目标对象对应的目标上行传输的时间，所述下行时间差是第一下行传输时间与第二下行传输时间之间的差值，所述第一下行传输时间是终端接收到所述第一目标对象对应的下行传输的时间，所述第二下行传输时间是终端接收到所述第二目标对象对应的下行传输的时间。
所述第一目标TAC与第一目标对象关联。
可以理解，S310的实现过程除了可以参照前述方法实施例200中的相关描述之外，作为一种可能的实现方式，所述终端可以根据TA调整颗粒度，周期性的调整目标上行传输的时间。例如，如果所述TA调整颗粒度为0.5个slot，那么，所述终端可以每隔0.5个slot进行一次目标上行传输的时间调整。
此外，对于前述所述终端目标方式调整目标上行传输的时间的过程，下面将结合示例1-示例2，对其实现过程做进一步说明，内容如下。
示例1
假设所述目标方式包括前述方式1，所述第一目标对象包括第一对象和第二对象，所述第一目标TAC包括与所述第一对象关联的第一TAC以及与所述第二对象关联的第二TAC，那么，所述终端可根据第一TAC计算第一TA，以及根据所述第二TAC计算第二TA，再基于所述第一TA对所述第一对象对应的目标上行传输的时间进行调整，以及基于所述第二TA对所述第二对象对应的目标上行传输的时间进行调整。
可选的，所述终端基于所述第一TA对所述第一对象对应的目标上行传输的时间进行调整，以及基于所述第二TA对所述第二对象对应的目标上行传输的时间进行调整的过程可以包括以下(11)-(12)任一项。
(11)基于参考对象对应的下行传输时间和所述第一TA对所述第一对象对应的目标上行传输的时间进行调整，以及基于参考对象对应的下行传输时间和所述第二TA对所述第二对象对应的目标上行传输的时间的进行调整，所述参考对象为所述第一对象或所述第二对象。可以理解，在该(11)的实现过程中，所述第一对象对应的下行传输时间与第二对象对应的下行传输时间相同，或者，二者的差值小于第一阈值，该第一阈值的大小可以由协议约定或高层配置等实现，在此不做限制。
(12)基于所述第一对象的下行传输时间和所述第一TA对所述第一对象对应的目标上行传输的时间进行调整，以及基于所述第二对象的下行传输时间和所述第二TA对所述第二对象对应的目标上行传输的时间进行调整。可以理解，在该(12)的实现过程中，所述第一对象对应的下行传输时间与第二对象对应的下行传输时间之间的差值大于或等于第二阈值，该第二阈值的大小可以由协议约定或高层配置等实现，在此不做限制。当然，前述的第一阈值与第二阈值可以相同或不同。
当然，在本示例1中，针对多个对象(如第一对象、第二对象)对应的目标上行传输的时间的调整，多个对象可以共用一个TA进程(Process，也即物理层维护一个上行帧(UL Frame))，再通过MAC层维护多个TAC来实现多个对象对应的上行传输分别采用不同的TA来调整上行传输的时间；或者，多个对象对应的目标上行传输也可以分别采用多个独立的TA Process(即物理层维护多个独立的UL Frame)，再通过MAC层维护多个TAC来实现多个对象对应的上行传输分别采用不同的TA来调整上行传输的时间。
基于此，下面以所述第一目标对象包括第一对象和第二对象，所述第一 目标TAC包括与所述第一对象关联的第一TAC以及与所述第二对象关联的第二TAC为例，对前述两种情形进行介绍。
情形1
如图4a所示，假设第一对象和第二对象共用一个TA进程，那么，所述终端基于同一上行帧(UL Frame)的不同时隙(如图4a中所示的slot1-slot8)分别进行物理上行共享信道(Physical uplink shared channel，PUSCH)1(即第一对象对应的目标上行传输)和PUSCH2(即第二对象对应的上行传输)的传输时间的调整。
需要注意的是，在此情形中，考虑到第一对象和第二对象共用一个TA进程，所述终端确定目标上行传输对应的TAC的过程可以包括：所述终端接收所述第一目标对象对应的目标上行传输的配置授权信息；以及根据所述配置授权信息确定所述第一目标TAC为所述目标上行传输对应的TAC。例如，所述终端根据所述目标上行传输的配置授权信息，确定与所述目标上行传输关联的所述第一目标对象；将与所述第一目标对象关联的第一目标TAC确定为所述目标上行传输的TAC。本实施例中，所述配置授权信息可以包括动态授权(dynamic grant)、配置授权(configured grant)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、SRS配置(configure)等。
基于此，在一种实现方式中，所述目标上行传输与第一目标对象之间的关联关系可通过以下(21)-(24)中的任一项配置。
(21)根据第一RRC信令配置；例如，可通过第一RRC配置周期或者半持续的SRS、物理上行控制信道(Physical Uplink Control Channel，PUCCH)关联CoresetPoolIndex。
(22)根据目标控制资源集(Control resource set，Coreset)所关联的CoresetPoolIndex配置，其中，调度所述目标上行传输的下行控制信息(Downlink Control Information，DCI)来自所述目标Coreset。
例如，假设第一目标对象包括第一对象和第二对象，调度所述目标上行传输的目标DCI来自关联CoresetPoolIndex为0的目标Coreset，则，所述目标上行传输关联第一对象；如果调度目标上行传输的目标DCI来自关联CoresetPoolIndex为1的目标coreset，则所述目标上行传输关联第二对象。
又例如，假设第一目标对象包括第一对象和第二对象，如果终端检测到来自CoresetPoolIndex为0的目标coreset的目标DCI，则在检测所述目标DCI的PDCCH时机(occasion)的K个时间单位之后的所有目标上行传输都关联第一对象；如果终端检测到来自CoresetPoolIndex为1的目标coreset的目标DCI，则在检测所述目标DCI的PDCCH occasion的K个时间单位之后的所有目标上行传输都关联第二对象。
(23)根据目标上行传输的信道分组确定。例如，属于信道分组1的目标上行传输与第一对象关联，属于信道分组2的目标上行传输与第二对象关联，……。
(24)根据目标上行传输的波束确定。例如，在所述目标上行传输的波束为波束X时，所述目标上行传输与第一对象关联，在所述目标上行传输的波束为波束Y时，所述目标上行传输与第二对象关联。其中，这里得波束可以指TCI状态，其中X可以表示第一个TCI状态，Y可以表示第二个TCI状态。
进一步，所述终端在确定目标上行传输对应的TAC(如第一目标TAC) 之后，所述终端可周期性的调整所述第一目标对象对应的目标上行传输的时间，下面结合(31)和(32)对其实现过程进行说明。其中，假设所述第一目标对象包括第一对象和第二对象，所述第一目标TAC包括与所述第一对象关联的第一TAC以及与所述第二对象关联的第二TAC。
(31)在第一周期定时器运行期间，根据所述第一TAC调整所述第一对象对应的目标上行传输的时间，在所述第一周期定时器超时重启所述第一周期定时器，以及在重启后的所述第一周期定时器运行期间，根据所述第二TAC调整所述第二对象对应的上行传输的时间，所述第一周期定时器的首次启动与第一时间同步计时器(Time Alignment Timer，TAT)的启动相关；由此，通过重复启动所述第一周期定时器，实现对所述第一对象对应的上行传输的时间以及对所述第二对象对应的上行传输的时间的周期性调整。
例如，请结合参阅图4b，本实施例中定义一个第一周期定时器，基于此，所述终端在启动第一TAT的同时启动第一周期定时器(如TAT 1)，那么，在TAT 1第一次运行期间，所述终端根据所述第一TAC调整所述第一对象对应的目标上行传输的时间，如果TAT 1超时，则重启TAT 1，并在TAT1第二次运行期间，所述终端根据所述第二TAC调整所述第二对象对应的目标上行传输的时间，如此重复，实现对第一对象和第二对象分别对应的目标上行传输的时间的调整。
(32)在第二周期定时器运行期间，终端根据所述第一TAC调整所述第一对象对应的目标上行传输的时间，在第三周期定时器运行期间，终端根据所述第二TAC调整所述第二对象对应的目标上行传输的时间，其中，所述第二周期定时器和所述第三周期定时器交替运行，所述第二周期定时器的首次 启动与第一TAT的启动相关。
例如，请结合参阅图4c，本实施例中定义一个第二周期定时器和第三周期定时器，基于此，所述终端在启动第一TAT的同时启动第二周期定时器(如TAT2)，那么，在TAT2运行期间，所述终端根据所述第一TAC调整所述第一对象对应的目标上行传输的时间，如果TAT2超时，则启动第三周期定时器(如TAT3)，并在TAT3运行期间，所述终端根据所述第二TAC调整所述第二对象对应的目标上行传输的时间，如此重复，实现对第一对象和第二对象对应的上行传输的时间的分别调整。其中，所述第二周期定时器的定时长度和所述第三周期定时器的定时长度可以相同，也可以不同。
需要注意的是，所述第一TAT是所述终端在接收到所述MAC CE、且所述MAC CE中包括第一TAC和第二TAC时启动，或所述第一TAT是所述终端在接收到第一TAC或第二TAC时启动，或所述第一TAT是重启的TAT等。所述第一对象和所述第二对象对应同一所述第一TAT，也即所述终端基于同一TA进程进行第一对象和第二对象对应的目标上行传输时间的调整。
情形2
如图4d所示，假设第一对象和第二对象分别对应一个独立的TA进程，如TA进程1、TA进程2，那么，所述终端基于不同的UL Frame分别进行PUSCH1(即第一对象对应的目标上行传输)和PUSCH2(即第二对象对应的上行传输)的传输时间的调整。
基于此，考虑到所述终端在接收到MAC CE时启动TAT(即第二TAT)、且所述第一对象和第二对象分别对应不同的TAT(即所述第一对象与所述第二对象对应不同的所述第二TAT)，那么，如果第三目标对象(第一对象或第二对象)对应的第二TAT过期，所述终端可以执行以下(41)-(42)中的 任一项。
(41)释放(或清除)发往所述第三目标对象的全部上行传输，其中，所述全部上行传输可以包括但不限于混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)传输、SRS、PUCCH、配置授权(Configured Grant，CG)、半持续调度(Semi-Persistent Scheduling，SPS)、半持续信道状态信息(Semi-Persistent Channel State Information，SP-CSI)等。
(42)释放发往所述第三目标对象的第一信号，其中，所述第一信号包括SRS、PUCCH、CG、SPS、SP-CSI中的至少一项。
相应的，如果所述第一对象对应的第二TAT以及所述第二对象对应第二TAT均过期，那么，所述终端可释放发往所述第一对象和所述第二对象的全部上行传输。
此外，考虑到第一对象和第二对象分别对应一个独立的TA进程，那么，所述终端在进行目标上行传输的时间调整时，可以引入TA进程标识(process ID)来区分两个TA进程，如i＝CoresetPoolIndex或者i＝物理层小区标识(Physical Cell Identifier，PCI)。
示例性的，调整后的时间可以如式(1)所示。
其中，为调整后的目标上行传输的时间，为调整前的目标上行传输的时间，TA(i)为通过TAC所指示的TA，i是TA process ID，基于此，如果是对第一对象对应的目标上行传输时间进行调整，那么，i＝1，如果是对第二对象对应的目标上行传输时间进行调整，那么，i＝2，μ表示子载波间隔，本实施例中，μ为正整数，如1、2、3……。
需要注意，在一种实现方式中，所述终端在接收MAC CE之前，还可以接收第二RRC信令；其中，所述第二RRC信令中可以包括以下(51)-(52)中的至少一项。

示例2
假设所述目标方式包括前述方式1和方式2，那么，所述终端可以如图4e所示，以第一目标对象的下行传输时间为参考(或基准)，根据第一目标TAC调整第一目标对象对应的目标上行传输的时间，以及根据第一目标TAC和下行时间差(第一目标对象对应的下行传输时间与第二目标对象对应的下行传输时间之间的差值)来调整第二目标对象对应的目标上行传输的时间。
或者，所述终端也可以如图4f所示，以第二目标对象的下行传输时间为基准，根据第一目标TAC调整第一目标对象对应的目标上行传输的时间，以及根据第一目标TAC和下行时间差(第一目标对象对应的下行传输时间与第 二目标对象对应的下行传输时间之间的差值)来调整第二目标对象对应的目标上行传输的时间。
可以理解，以图4e为例，所述终端根据所述第一目标TAC调整所述第一目标对象对应的目标上行传输的时间的时，调整后的目标上行传输的时间可以如式(2)所示。

对于前述的示例2，对于同一目标对象(如第一目标对象)，如果MAC  CE中携带coresetPoolindex，所述终端利用接收到的所述MAC CE替换已保存的MAC CE，即使携带了不同的coresetPoolindex。
进一步，对于前述的示例1和示例2，考虑到在所述第一目标TAC的生效时间内，所述终端需要进行目标上行传输时间的调整，因此，为了提高通信性能，在所述第一目标TAC的生效时间内，所述终端执行以下(61)-(63)中的至少一项。
(61)不期望接收到除与所述第一目标TAC关联的第一目标对象之外的其他对象的上行传输调度信息。
(62)将在所述第一目标TAC的生效时间内产生的第二信号确定为所述第一目标对象的对应的目标上行传输，所述第二信号包括SRS、PUCCH、CG中的至少一项。也即，在一个第一目标对象的TAC生效时间内产生的SRS、PUCCH、CG全都发往该第一目标对象。当然，所述终端在进行第二信号发送时，波束(Beam)采用所述第一目标对象对应的公共(common)beam。这里的公共波束为当前生效的TCI状态。
(63)确保两个目标对象调度的两个PUSCH之间的间隔至少为一个slot，由此确保后一个PUSCH不会因为时隙缩短导致性能降低。
此外，在所述第一目标TAC的生效时刻与前一个生效的TAC的生效时刻之间的时间间隔小于所述TA调整颗粒度的情况下，所述终端延后所述第一目标TAC的生效时刻，以使所述第一目标TAC的生效时刻与前一个生效的TAC的生效时刻之间的时间间隔大于或等于TA调整颗粒度，并基于延后的所述第一目标TAC的生效时刻执行所述基于目标方式和/或TA调整颗粒度调整目标上行传输的时间的步骤。换言之，在本申请中，所述终端不期望两个相邻TAC的生效时刻之间的间隔小于TA调整颗粒度。
本实施例中，能够实现两个对象的上行传输采用独立的TA调整，保证 了每个对象上不同用户的上行传输的到达时间相同或者在一个CP内，由此，有效的降低了用户间干扰，提升上行传输的性能。
