Description

一种传输配置方法、装置、通信节点和通信设备
本申请要求在2019年5月17日提交中国专利局、申请号为201910413433.2的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本文涉及但不限于一种传输配置方法、装置、通信节点、通信设备和计算机可读存储介质。
背景技术
在卫星通信场景中，由于LEO(Low Earth Orbiting，低地球轨道)卫星基站相对地球快速移动，即使地面终端保持静止，也会经历由于卫星移动性引起的多普勒频偏。
在当前3GPP NTN SI(3rd Generation Partnership Project Non Terrestrial Networks Study Item，第三代合作伙伴计划非陆地网络研究项目)讨论中，普遍共识是在卫星基站侧对于频偏进行校正。因为卫星基站是在固定星轨上周期性运行，因此对于一个给定波束，卫星基站相对于该波束地面覆盖区域中心点的相对速度可预先计算。根据此相对速度可以计算该波束相应地面覆盖区域中心点位置上，一个静止用户经历的多普勒频偏。然后根据所算得的多普勒频偏，校正该给定波束的发射下行信号，如图1所示。
但是，即使基站在发射下行信号时进行了上述多普勒频偏校正，处于非波束中心点的用户仍可能经历较大的残余多普勒频偏，此残余多普勒频偏在其上行发射中到达基站侧可能会造成上行用户干扰。而且由于卫星基站到终端的传输距离很远，导致时延过大，因此终端需要调整上行发射TA(Time Advance，时间提前)，否则会导致时域信息重叠，产生干扰。

在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在低轨卫星通信系统中，由于卫星高速运动导致的多普勒频偏会影响OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)系统中子载波的正交性，这对于上行基站接收性能要求比较高。此外，大的RTT(Round-Trip Time，往返时延)下，对系统调度也会产生影响。
即使基站在发射下行信号时进行了多普勒频偏校正，处于非波束中心点的终端仍可能经历较大的残余多普勒频偏。尤其对于星下点波束覆盖范围内终端以及高速移动的终端而言，此残余多普勒频偏在其上行发射中到达基站侧会造成上行用户自干扰和多用户间干扰。而且由于卫星基站到终端的传输距离很远，导致时延过大，因此终端需要调整上行发射TA(Time Advance，时间提前)，否则会导致时域信息重叠，产生干扰。
本公开实施例中，通信节点可以使用特定的传输配置发射相应的信令指示 给通信设备，通信设备在获取该指示时，可以依照该信令指示，自身能力等，在其发射上行信号时，选择合适的资源和上行传输方式(如校正上行频偏或不校正上行频偏，或者基于已知信息自主调整上行发射TA)。

其中，所述上行传输方式可包括是否执行校正和是否执行资源选择中的至少之一。
在一实施例中，步骤202包括：
所述通信设备根据自身校正的能力和所述校正指示信息，确定上行传输方式。
例如，在校正状态信息为需要校正，且通信设备的自身校正的能力可以进行校正时，通信设备执行校正；
在校正状态信息为需要校正，且通信设备的自身校正的能力不能进行校正时，通信设备不执行校正；
在校正状态信息为无需校正，通信设备不执行校正；
在校正状态信息为自行选择是否校正，且通信设备的自身校正的能力可以进行校正时，通信设备可选执行或不执行校正；
在校正状态信息为自行选择是否校正，且通信设备的自身校正的能力不能进行校正时，通信设备不执行校正。
对于频偏校正，通信设备可以利用SSB收到的下行频点，与最接近的全局同步栅格绝对频点进行对比，计算两者之间频率差异，若执行频偏估计，通信设备以上述频率差异的两倍作为上行频偏校正值，校正上行发射信号，使其到达通信节点侧时在频域对齐。若不执行频偏估计，则不进行频偏校正，直接发射上行信号。通信设备根据信令指示的三种状态在相应上行传输资源上发射上行信号。
在一实施例中，所述方法还包括：

所述上行传输资源可以是RACH资源，也可以是PUSCH(Physical Uplink Shared Channel，物理上行共享信道)资源、PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)资源。
在一实施例中，所述通信设备按照所述上行传输方式选择其中一套传输配置信息，确定对应的上行传输资源，包括如下至少之一：
所述通信设备按照所述上行传输方式和目标标识选择一套传输配置信息；
所述通信设备选择第一套传输配置信息作为上行传输的默认配置。
其中，所述目标标识(ID)可以为：小区标识、SSB标识、CSI-RS的资源标识、终端标识、终端组标识、SRS资源标识、SRS资源索引。在一实施例中，所述上行信号携带所述通信设备的校正的能力信息。
校正的能力信息可用于通信节点确定所述通信设备是否有能力执行校正，从而发送后续的下行信令指示。
本公开实施例通过下行信令指示携带传输状态信息，使得通信设备可以根据下行信令指示进行校正，从而缓解上行接收中的多用户干扰或用户自身ICI，提升上行接收性能。
下面以通信节点为卫星基站，通信设备为终端为例，分别针对频偏校正和时偏校正进行说明。
一、频偏校正
对一个给定波束，卫星基站可计算得到该波束地面覆盖区域的中心位置上，一个静止终端所经历的多普勒频偏fd，在发射下行信号时，对该波束下所有下行信号进行2*fd的多普勒频偏校正。
由图4可知，经过2*fd的下行多普勒频偏校正，对于给定波束覆盖范围中心点上的静止终端，基站上行接收频率中消除了多普勒频偏的影响。
对于星下点波束覆盖范围内的终端，多普勒频偏校正为零，而该区域边缘终端的多普勒频偏仍有可能较大。对于仰角较大的其他波束，或对于高速移动终端(例如飞机终端)，经过上述步骤进行多普勒频偏校正之后，仍然可能存在较大的残余频偏。通过本公开实施例，残余频偏可以通过如下步骤得到校正：
第一步，基站指示(此时下行信令指示为频偏校正信令指示)，有3种可能：
1、在卫星基站的下行广播信号中加入基于波束的频偏校正信令指示，告知此波束覆盖内的所有终端，要求所有终端执行、不执行或选择性执行频偏估计和上行频偏校正。
2、在卫星基站的专用下行控制信令中加入基于终端的频偏校正信令指示。 针对该终端发射下行控制信令，要求该终端执行、不执行或选择性执行频偏估计和上行频偏校正。
3、在卫星基站的公共下行控制信令中加入基于终端组的频偏校正信令指示。针对某一组终端发射下行控制信令，要求该终端组内所有终端执行、不执行或选择性执行频偏估计和上行频偏校正。
第二步，终端行为，具体包括2个动作。
1、终端接收上述3种可能的信令指示，执行、不执行或选择性执行频偏估计。一种可行方法是，利用SSB收到的下行频点，与最接近的全局同步栅格绝对频点进行对比，计算两者之间频率差异。
2、若执行频偏估计，终端以上述频率差异的两倍作为上行频偏校正值，校正上行信号，使其到达基站侧时在频域对齐。若不执行频偏估计，则不进行频偏校正，直接发射上行信号。终端应根据信令指示的三种状态在相应RACH资源上发射上行信号(类似的，对PUSCH/PUCCH而言，则为在PUSCH/PUCCH资源上发射上行信号)。
基站侧还可执行额外的保护措施，以防止终端上行频偏校正出现异常。一个可行的方法是，若基站侧经过接收测量，发现某终端上行频偏校正异常，则基站在调度该终端时需留出相应频域保护间隔，以规避该终端对于其他终端的上行信号干扰。
第三步，基站根据信令指示及收到的上行信号中占用的资源情况，可知终端是否进行了校正，并发射下行RAR(Random Access Response，随机接入响应)。此时下行信令指示包含在下行RAR中。若在对应资源上监测到上行信号，则下行信令指示的RAR UL grant(Uplink grant，上行授权)中指示终端执行或不执行频偏校正，信令内容可以包括校正值参数。终端在非初始接入时，基站会假设频偏都已校正，并根据RAR UL grant中的信令指示进行后续资源分配等操作。
二、时偏校正
终端初始接入时，对某一波束，基站首先通过下行广播发射一个TA调整信令指示(此时下行信令指示为TA调整信令指示)，信令指示中要求所有终端执行、不执行或选择性执行时偏校正以及波束覆盖范围内所有终端共同TA (common TA)调整值。
其中，执行时偏校正是指在共同TA调整值的基础上再自行调整，不执行时偏校正是指将共同TA调整值作为TA调整值。
终端收到指示后，根据自身情况可以执行如下之一：
1、选择直接将共同TA调整值作为TA调整值，并应用配置B在对应资源上发射上行RACH信号，并上报是否具有自行调整能力，其中配置B对应不执行校正。
2、选择在共同TA调整值的基础上再自行调整，并应用配置A在对应资源上发射上行RACH信号，并且上报是否具有自行调整能力，其中配置A对应执行校正。
影响是否自行调整的因素，可以是终端是否有能力根据位置信息计算出自身实际TA调整值与共同TA的差值，也可以是有能力计算自行调整值的终端对上行同步误差预估后判断是否需要调整。
基站接收到对应终端的上行信号后，可知终端的调整能力以及是否进行了自行调整。
传输状态，可以是(将共同TA作为TA调整值的基础上)需进行自行TA调整，无需进行自行TA调整，选择性进行自行TA调整。也可以是需进行TA调整，无需进行TA调整，选择性进行TA调整。前者是指终端必须进行TA调整，但是否在共同TA基础上再自行调整则根据信令指示和自身实际情况，后者是指终端不一定要进行TA调整(比如共同TA也可以不进行补偿)，是否进行TA调整则根据信令指示和自身实际情况决定。
1、对于具有自行调整能力的终端，且公共TA不能满足上行同步误差要求时，基站可单播或组播发射下行信令指示，告知终端需进行自行TA调整。
2、对于具有自行调整能力的终端，且公共TA能满足上行同步误差要求时，基站可单播或组播发射下行信令指示，告知终端选择性进行自行TA调整。
3、对于没有自行调整能力的终端，且公共TA不能满足上行同步误差要求时，基站重新计算终端所需的TA调整值，单播或组播发射下行信令指示，告知终端无需自行调整TA并使用信令指示中更新后的TA调整值。
4、对于没有自行调整能力的终端，且公共TA能满足同步误差要求时，基站可单播或组播发射下行信令指示，告知终端无需进行自行TA调整。
非初始接入时，基站可根据已知的终端能力以及终端同步情况执行上述操作，下行发射对应的信令指示。
需要说明的是，下行信令指示中所有终端共同TA调整值并不是必须的，基站也可以指示终端不调整共同TA调整值，基站发射下行信令指示的方式可以是通过广播、单播或组播的方式。基站侧根据情况采取相应的措施，例如选择在接收时将接收时间窗延后等。
下面以一些应用实例进行说明。
卫星波束方向控制，目前有两种方式：移动波束(moving beam)和凝视波束(steering beam)。移动波束方式下，波束方向相对卫星是静止的，其覆盖区域随卫星的移动而做相应移动；凝视波束下，其覆盖区域相对地面或移动中的终端群是静止的，波束方向随卫星的移动而改变。针对不同的波束类型，可以选择适用的信令指示方式。
应用实例1:低速终端，非地球静止轨道卫星基站，移动波束
对于低速终端而言，多普勒频偏主要由卫星的运动引起。基站下行发射信号经过2*fd的多普勒频偏校正之后，残余多普勒频偏最大值在星下点波束的边缘处，故下面考虑星下点波束的情况，若该情况的残余多普勒频偏可以得到校正，则其他情况下均可以得到校正。针对图1中星下点波束覆盖区域而言，基站侧的多普勒频偏校正为0，而该覆盖区域边缘的终端所经历的多普勒频偏仍然较大，表1给出了不同情况下的星下点波束最大多普勒频偏。
表1不同情况下星下点波束的最大多普勒频偏
Figure PCTCN2020090137-appb-000001
从表中可以看出，若卫星基站选择LEO-600，载波为2GHz，子载波间隔选择为5kHz时，最坏情况下(图1中星下点波束边缘终端)，卫星基站接收到的上行信号频率会包含频偏为2.68*2＝5.32kHz，因此会造成子载波错位，严重影响上行接收性能。
由于移动波束情况下，星下点波束方向保持不变，故卫星基站的下行广播信号中可加入基于波束的频偏校正信令指示，状态为“需要频偏校正”，告知此波束覆盖内的所有终端，执行频偏估计和上行频偏校正，并应用配置A发射上行RACH信号(类似的，对PUSCH/PUCCH而言，则为PUSCH/PUCCH信号)。卫星基站侧在配置A指定的资源上接收RACH信号，若在对应资源上监测到上行信号，则RAR UL grant中信令指示终端执行频偏校正。
在频率范围为3GHz以下时，全局同步栅格各频点之间的频率间隔为最小50kHz，在频率范围为3GHz-24.25GHz时，频率间隔为1.44MHz，在频率范围为24.25GHz-100GHz时，频率间隔为1.72MHz，而残余多普勒频偏最大为7.68kHz，因此对比SSB接收的下行频点和最近的全局同步栅格即可计算出残余频偏，从而进行上行频偏校正。
应用实例2:静止终端，非地球静止轨道卫星基站，凝视波束
对于凝视波束覆盖范围内的静止终端，由于波束覆盖区域相对地面不变，因此该波束的仰角随着卫星的移动而逐渐变化。则在卫星基站侧执行下行多普勒频偏校正后，仍可能有较大的残余频偏。因此卫星基站可下行发射选择性频偏校正指示，可以采用如下3种方式进行上行频偏校正指示。
a、卫星基站的下行广播信令中可加入基于波束的频偏校正信令指示，告知此波束覆盖内的所有终端，选择性执行频偏估计和上行频偏校正。若执行校正，则应用配置A并在其指定资源上发射上行RACH信号(类似的，对PUSCH/PUCCH而言，则为PUSCH/PUCCH信号)；若不执行校正，则应用配置B并在其指定资源上发射上行RACH信号。
b、假如卫星基站以窄波束(点波束)进行针对单终端的数据传输，则可在卫星基站的专用下行控制信令中加入基于终端的频偏校正信令指示。针对该终端发射下行控制信令，要求该终端选择性执行频偏估计和上行频偏校正。若执行校正，则应用配置A并在资源A上发射上行信号；若不执行校正，则应用配 置B并在资源B上发射上行信号。
c、假如卫星基站已知终端地理位置，则卫星基站可基于地理位置将终端进行分组。在卫星基站的公共下行控制信令中加入基于终端组的频偏校正信令指示。针对某一组终端(如地理位置接近，残余频偏可能较大)发射下行控制信令，要求该终端组内所有终端选择性执行频偏估计和上行频偏校正。若执行校正，则应用配置A并在其指定资源上发射上行信号；若不执行校正，则应用配置B并在其指定资源上发射上行信号。
上述校正指示信息可以通过终端运动状态为静止，波束方向控制方式为凝视波束，服务网络为NTN网络来确定。上述传输配置对应的目标标识可以为小区标识，终端标识，终端组标识，同步信号块SSB标识，SRS资源标识等。
卫星基站侧在不同指定资源上分别接收，若在对应资源上监测到上行信号，则RAR UL grant中信令指示终端执行或不执行频偏校正。
终端频偏估计和上行频偏校正方法同应用实例1。
应用实例3:高速终端(1000km/s),非地球静止轨道卫星基站，移动波束或凝视波束
对于高速终端而言，不论处于移动波束覆盖范围下还是凝视波束覆盖范围下，除了考虑由卫星基站运动引起的多普勒频偏以外，其自身运动引起的多普勒频偏也需要考虑。在卫星基站侧经过2*fd的多普勒频偏校正之后，残余多普勒频偏由终端和卫星基站的共同运动引起。
卫星基站下行发射的信令指示状态应为“需要频偏校正”，可以采用如下2种方式进行上行频偏校正指示。
a、假如卫星基站以窄波束(点波束)进行针对单终端的数据传输，则可在卫星基站的专用下行控制信令中加入基于终端的频偏校正信令指示。针对该终端发射下行控制信令，要求该终端执行频偏估计和上行频偏校正，且应用配置A发射上行信号。
b、假如卫星基站已知终端运动状态(例如速度)，则卫星基站可基于终端运动状态将终端进行分组。在卫星基站的公共下行控制信令中加入基于终端组的频偏校正信令指示。针对某一组终端(如速度接近，残余频偏可能较大)发射下行控制信令，要求该终端组内所有终端执行频偏估计和上行频偏校正，且 应用配置A在其指定资源上发射上行信号。
卫星基站侧在配置A指定的资源上接收RACH信号(类似的，对PUSCH/PUCCH而言，则为PUSCH/PUCCH信号)，若在对应资源上监测到上行信号，则RAR UL grant中信令指示终端执行频偏校正。
终端频偏估计和上行频偏校正方法同应用实例1。
应用实例4：高度相差较大(如地面终端和高空终端(10km))的终端共存
对于地面终端和高空终端而言，由于高度不同，相对卫星基站的时延也不同，因此初始接入时，基站可以在下行信令指示中包含两个共同TA(common TA)调整值，且对两个TA调整值标记对应的时偏校正值类型，终端根据自身情况选择对应的共同TA调整值，以及是否在共同TA调整值的基础上进行自行调整，在对应资源上发射上行RACH信号(类似的，对PUSCH/PUCCH而言，则为PUSCH/PUCCH信号)，并上报是否具有自行调整能力。
基站根据终端的上行信号可知终端TA调整值对应的时偏校正值类型、终端是否有TA调整值的自行调整能力，以及是否进行了自行调整。基站根据同步误差情况执行如下之一：
a)对误差超过阈值，且有自行调整能力的终端通过单播或组播方式发射下行信令指示，告知终端在共同TA调整值上进行自行调整；
b)对误差超过阈值，且没有自行调整能力的终端，通过单播或组播方式发射下行信令指示，告知终端无需自行调整，并使用基站更新后的TA调整值；
c)对误差未超过阈值的终端，通过单播或组播方式发射下行信令指示，告知终端无需自行调整，直接使用共同TA调整值。
非初始接入时，基站可根据已知的终端能力以及终端同步情况执行上述操作，下行发射对应的信令指示。
