Description

电子装置、无线通信方法和计算机可读介质
本申请要求于2019年7月8日提交中国专利局、申请号为201910609787.4、发明名称为“电子装置、无线通信方法和计算机可读介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开一般涉及无线通信领域，更具体地，涉及用于非地面网络(Non-terrestrial networks，NTN)通信的电子装置、无线通信方法以及计算机可读介质。
背景技术
第三代合作伙伴项目(3GPP)已经提出将卫星通信作为诸如飞机通信、海上船舶和偏远地区回程等场景中的选择，并建议充分利用卫星的能力。
发明内容
与地面网络通信不同，在NTN通信中，由于例如低轨道卫星(LEO)的快速移动和地球同步轨道卫星(GEO)的超大时延等，可能导致信道测量的结果不准确或者是过期的(out of date)。一个可能的应对方式是基于卫星移动信息和用户设备(UE)的位置计算上行参数。然而，并不是所有的UE都具有全球导航卫星系统(GNSS)功能，而且由于信道的复杂性，仅根据UE位置和卫星移动信息计算的上行参数可能不准确。
在下文中给出了关于本发明实施例的简要概述，以便提供关于本发明的某些方面的基本理解。应当理解，以下概述并不是关于本发明的穷举性概述。它并不是意图确定本发明的关键或重要部分，也不是意图限定本发明的范围。其目的仅仅是以简化的形式给出某些概念，以此作为稍后论述的更详细描述的前序。
根据一个实施例，提供一种用于无线通信的电子装置，其包括处理电路。处理电路被配置为根据UE的能力和/或UE与用于NTN通信的基站之间的信道情况，从分别对应于上行传输参数的不同获取方式的两个或更多个上行传输模式中确定用于UE的上行传输模式。处理电路还被配置为进行控制以基于所 确定的上行传输模式进行UE到基站的上行传输。
根据另一个实施例，一种无线通信方法包括：根据UE的能力和/或UE与用于NTN通信的基站之间的信道情况，从分别对应于上行传输参数的不同获得方式两个或更多个上行传输模式中确定用于UE的上行传输模式；以及基于所确定的上行传输模式进行UE到基站的上行传输。
本发明实施例还包括计算机可读介质，其包括可执行指令，当可执行指令被信息处理设备执行时，使得信息处理设备执行根据上述实施例的方法。
通过本公开实施例，使得UE能够使用更合适的上行传输模式，从而提高系统效率。
附图说明
本发明可以通过参考下文中结合附图所给出的描述而得到更好的理解，其中在所有附图中使用了相同或相似的附图标记来表示相同或者相似的部件。所述附图连同下面的详细说明一起包含在本说明书中并且形成本说明书的一部分，而且用来进一步举例说明本发明的优选实施例和解释本发明的原理和优点。在附图中：

具体实施方式
下面将参照附图来说明本发明的实施例。在本发明的一个附图或一种实施方式中描述的元素和特征可以与一个或更多个其它附图或实施方式中示出的元素和特征相结合。应当注意，为了清楚的目的，附图和说明中省略了与本发明无关的、本领域普通技术人员已知的部件和处理的表示和描述。
如图1所示，根据本实施例的用于无线通信的电子装置100包括处理电路110。处理电路110例如可以实现为特定芯片、芯片组或者中央处理单元(CPU)等。
处理电路110包括确定单元111和控制单元113。需要指出，虽然附图中以功能块的形式示出了确定单元111和控制单元113，然而应理解，各单元的功能也可以由处理电路作为一个整体来实现，而并不一定是通过处理电路中分立的实际部件来实现。另外，虽然图中以一个框示出处理电路，然而电子装置可以包括多个处理电路，并且可以将各单元的功能分布到多个处理电路中，从而由多个处理电路协同操作来执行这些功能。
如后面将结合具体实施例说明的，电子装置100可以实现在基站侧或UE侧。
确定单元111被配置为根据UE的能力和/或UE与用于NTN通信的基站之间的信道情况，从两个或更多个上行传输模式中确定用于UE的上行传输模式。上述两个或更多个上行传输模式分别对应于该UE获得上行传输参数的不同方式。
根据一个实施例，上行传输模式可以包括以下第一模式、第二模式和第三模式。
在第一模式下，UE使用对应于不同的卫星轨道信息而预定义上行参数组，或者通过对应于不同的卫星轨道信息而预定义的上行参数计算公式得到上行参数组，并使用上行参数组进行上行传输。在本文中，第一模式也可以被称为 开环模式。
在第二模式下，UE根据来自基站的指示得到上行传输参数，并使用所得到的上行传输参数进行上行传输。在本文中，第二模式也可以被称为闭环模式。
在第三模式下，UE根据其定位信息以及卫星轨道信息计算出上行传输参数，并使用所计算的上行传输参数进行上行传输。在本文中，第三模式也可以被称为半开环模式。
卫星轨道信息例如可以包括卫星的移动类型(mobility type)，移动类型可以是根据卫星的星历图信息的至少一部分确定的。根据一个实施例，星历图信息的至少一部分可以包括卫星的高度信息和倾斜角信息。
此外，卫星的移动类型与卫星轨道信息之间的对应关系可以是基站和UE共知的。例如，卫星的移动类型可以由基站广播并由UE接收以用于获取卫星的轨道信息。
参照图5，卫星的轨道信息/星历图一般包括长轴、短轴、交点角Ω、近地点幅角ω、轨道倾角i、过近地点时刻tp等信息。通过这些参数可以确定任意时刻卫星的位置和速度。卫星基站的轨道信息通常是通过广播的方式发送给UE的，因此可能难以将所有这些信息都包含在广播信息中，一是由于这可能导致信息量过大，二是某些卫星的信息可能是保密的。通过定义移动类型，可以降低广播卫星轨道信息的数据量，提高UE获取卫星移动信息的准确度，同时可以提高卫星保密或适应不同政策的灵活性。
作为示例，可以与如下方式类似地定义移动类型：
移动类型1：卫星高度800km、倾斜角0°、过近地点时刻tp1；
移动类型2：卫星高度600～700km、倾斜角0°～5°；
移动类型3：星历图信息，如DateTTR.A.(2000)Decl.DeltarElong.Phasem1m2200910260941.54+1309.21.7881.71169.332.916.6 200910310952.04+1254.91.7671.73671.832.916.6；
移动类型4：卫星高度35786km。
继续参照图1，控制单元113被配置为进行控制以基于所确定的上行传输模式进行UE到所述基站的上行传输。
根据一个实施例，在第一模式(开环模式)下，UE可以使用预定义的一组或多组上行参数或者通过预定义的计算公式计算出的一组或多组上行参数， 以预定时间间隔循环发送上行信号。
例如，对于被分配为开环模式的UE，其可以对应于不同的卫星基站轨道信息来使用预定义的上行参数组，或者可以对应于不同的卫星基站轨道信息来使用预定义上的行参数计算公式来计算出上行参数组，并且可以使用预定义的上行参数或者根据预定义的计算公式计算出的上行参数以一定的准则发送上行信号。另外，这种发送上行信号的方式也可以用作不具有GNSS功能的UE在进行初始接入时发送前导(preamble)的方式。
接下来，参照图6说明开环模式下的上行传输的示例过程。
基站例如通过系统信息块(SIB)将卫星的移动类型通知给UE。
UE例如可以通过查找表来根据卫星的移动类型确定预定义的上行参数组(或者可以根据预定义的计算公式计算出一组上行参数)，并使用上行参数组以一定的时间间隔循环发送上行信号。
如图6的示例所示，UE可以先使用第一上行功率和第一多普勒补偿发送物理随机接入信道(PRACH)，当预定时段内未收到基站的响应的情况下，可以使用第二上行功率和第二多普勒补偿发送PRACH，并且在收到PRACH响应后发送无线资源控制(RRC)连接请求。
此外，第二上行参数组例如可以是通过将第一上行参数组中的参数分别加上偏移值而得到的。例如，第一上行参数组为[多普勒补偿1,上行功率1]第二上行参数组为[多普勒补偿1+偏移量D,上行功率1+偏移量P]。
需要指出，上述示例仅仅是说明性的而非限制性的。
接下来，说明第二模式(闭环模式)下的上行传输的示例方式。在闭环模式下，UE根据来自基站的指示得到上行传输参数。根据一个实施例，来自基站的指示可以包括用于指示上行发送功率的发送功率控制(TPC)信息，和/或用于指示上行发送定时的提前量的定时提前量(TA)信息。
定时提前(timing advance)一般用于UE上行传输，是指为了将UE上行包在希望的时间到达基站而预估由于距离引起的射频传输时延，提前相应时间发出数据包。基站可以通过向UE发送定时提前命令(TAC:Timing Advance Command)来告知UE定时提前量大小。
在长期演进(LTE)系统中，基站可以通过测量UE的上行传输来确定每个UE的TA值。因此，只要UE有上行传输，基站就可以用上行传输来估计 TA值。理论上，UE发送的任何信号(包括但不限于探测参考信号(SRS)、解调参考信号(DMRS)、信道质量指示(CQI)、确认/否定确认(ACK/NACK)和物理上行共享信道(PUSCH)等)都可用于测量TA。在随机接入过程中，基站可以通过测量接收到的前导来确定定时提前量。
在NTN中，由于卫星基站的高速运动，UE与基站的距离可能不断改变。相应地，UE与基站的传输时延也可能不断改变，从而TA值需要相应地改变。
类似地，用于指示上行发送功率的TPC信息也可能需要相应地调整。
需要指出，闭环模式下根据基站指示得到的上行参数不限于上述示例。
接下来，说明第三模式(半开环模式)下的上行传输的示例方式。在半开环模式下，UE根据其定位信息以及卫星轨道信息计算出上行传输参数。根据一个实施例，定位信息可以包括UE的位置和速度，并且上行传输参数可以包括上行发送功率、上行多普勒频移补偿和/或上行定时提前量。
图7示出了半开环模式下的上行传输的示例过程。
首先，基站例如通过SIB将卫星的移动类型通知给UE。接下来，UE可以进行初始接入以及位置上报。此外，UE可以根据其定位信息以及卫星轨道信息计算出上行传输参数，并且基于所计算的上行参数进行上行传输。
下面以上行发送功率为例说明计算上行传输参数的示例方式。
UE在进行上行发送功率计算时，可以引入由于基站移动带来的影响。具体地，可以将上行发送功率计算为：
Figure PCTCN2020099806-appb-000001
其中，
P CMAX,F,C(i)是UE的最大发射功率；
P OPUSCH,b,f,c(j,orbit)是P O_NOMINAL_PUSCH,f,c(j)和P O_UE_PUSCH,b,f,c(j)的和。其中，如果UE没有被RRC配置P0-PUSCH-AlphaSet，那么P O_UE_PUSCH,b,f,c(j)＝0.P O_NOMINAL_PUSCH,f,c(0)＝P O_PRE+Δ PREAMBLE_Msg3，其中参数preambleReceivedTargetPower(前导接收目标功率，其针对P O_PRE)和msg3-DeltaPreamble(针对Δ PREAMBLE_Msg3) 由高层信令对特定的频段f和服务小区c进行配置；
Figure PCTCN2020099806-appb-000002
是PUSCH资源分配的带宽，其由服务小区c的载波f的有效上行带宽块b上的用于PUSCH传输机会i的资源块的数量表示，并且μ是子载波间隔配置；
a b.f.c(j)由高层参数α提供；
PL b,f,c(q d)是服务小区c的以dB为单位的下行路径损耗估计，其由US使用针对有效下行带宽块的参考信号(RS)指标q d计算；
Δ TF,b,f,c(i)是由调制编码方式(MCS)所确定的功率偏移量，UE的MCS是由基站来调度的，通过设置UE的发射MCS，可以较快的调整UE的发射功率谱密度，达到类似快速功控的效果；
f b,f,c(i,l,orbit)是根据物理下行控制信道(PDCCH)下行控制信息(DCI)中的功控命令TPC进行的调整值。
上述示例方式中采用了描述卫星基站的移动类型的参数。如前所述，不同移动类型对应于卫星的不同星历图信息或部分星历图特征信息，比如高度信息、倾斜角信息等，这种对应信息是基站和UE共知的，例如卫星基站可以向用户广播自身移动类型。
需要指出，在半开环模式下计算上行参数的方式不限于上述示例。
继续参照图1，根据一个实施例，确定单元111根据UE的能力来确定用于该UE的上行传输模式可以包括：对于具有GNSS功能的UE，将第三模式(半开环模式)为默认模式，而对于不具有GNSS功能的UE，以第一模式(开环模式)为默认模式。
为了节约成本，一些UE(例如某些物联网的终端)可能不具备定位功能。在UE不知道自身位置的情况下，不能通过基站广播的移动状态信息计算精确的多普勒频移补偿值和上行功率等。在这种情况下，例如可以通过循环发送上行信号，获得上行传输增益。对于具有定位功能的UE，由于卫星的移动性及卫星与UE的远距离导致的大时延，导致信道测量的结果可能不准确，因此可以使用基于卫星基站的移动性及UE位置的半开环计算方式。
另外，即使对于具有GNSS功能的UE，由于传输信道的复杂性(例如，如图9所示，当交通工具在复杂地形中行驶时)，仅依靠卫星的移动性和UE 位置信息决定的上行参数可能无法达到通信要求，此时需要基站根据对上行信号的测量进行调整。
根据一个实施例，确定单元111对上行传输模式的确定可以包括：在通过第一模式(开环模式)或第三模式(半开环模式)进行的上行传输的通信质量低于预定水平的情况下，将上行传输模式改变为第二模式(闭环模式)。
通信质量的指标例如可以包括参考信号接收功率(RSRP)、信干噪比(SINR)、参考信号接收质量(RSRQ)、接收信号强度指示(RSSI)等。RSRP表示在某个符号内承载参考信号的所有资源粒子(RE)上接收到的信号功率的平均值，是代表无线信号强度的关键参数以及物理层测量需求之一。SINR是指接收到的有用信号的强度与接收到的干扰信号(噪声和干扰)的强度的比值。RSRQ表示参考信号的接收质量，这种度量主要是根据信号质量来对不同候选小区进行排序，这种测量用作切换和小区重选决定的输入。RSRQ被定义为N*RSRP/(载波RSSI)之比，其中N是LTE载波RSSI测量带宽的资源块(RB)个数。RSRQ实现了一种有效的方式报告信号强度和干扰相结合的效果。RSSI用来判定链接质量，以及是否增大广播发送强度。
此外，确定单元111对上行传输模式的确定还可以包括：在通过第三模式(半开环模式)计算得到的上行传输参数与通过测量UE的上行信号得到的上行传输参数之间的差别大于预定水平的情况下，将上行传输模式改变为第二模式(闭环模式)。
图8示出了闭环模式下的上行传输的过程示例。
首先，基站例如通过SIB将卫星的移动类型通知给UE。接下来，UE可以进行初始接入以及位置上报。基站向UE发送道状态指示参考信号(CSI-RS)，并且UE基于对CSI-RS的测量发送CQI。此外，UE向基站发送调度请求，并且由基站向UE发送DCI。UE基于DCI确定上行参数例如ΔTF和MCS，并且基于该上行参数进行上行传输。
以上描述了多种上行传输模式的示例，包括开环模式、闭环模式和半开环模式。不同模式对应不同的上行信号发送行为。基站可以根据UE的能力及/或当前的信道情况决定UE使用那种上行发送模式。
例如，UE接入系统后，可以将其能力(例如是否具有GNSS功能)上报给基站，基站例如根据UE是否具有GNSS功能决定UE的上行传输模式是开 环还是半开环。
或者，UE接入系统后，可以将其位置信息上报给基站，基站通过UE位置和卫星基站的轨道信息计算得到第一上行参数组。此外，基站可以通过测量上行信号，例如前导、SRS等信息得到基站期待UE使用的第二上行参数组。通过比较第一和第二上行参数组，基站可以确定分配给UE哪种上行传输模式，例如是闭环模式还是半开环模式。
此外，UE接入系统后可以被配置为使用半开环模式的上行传输模式，但是由于信道情况的变化，基于UE侧计算的上行参数不再适用，基站例如可以通过RRC重配或者DCI的形式将UE的上行传输模式更新为闭环模式。
图10示出了上行传输模式的改变的过程示例。
首先，基站例如通过SIB将卫星的移动类型通知给UE。接下来，UE可以进行初始接入以及位置上报。此时，采用半开环模式的UE根据其定位信息以及卫星轨道信息计算出上行传输参数，并且基于所计算的上行参数进行上行传输。基站基于上行信号计算上行参数，确定UE应采用闭环模式进行上行传输，并将用于上行参数调整的指示通知给UE。接下来，UE采用经调整的上行参数进行上行传输。
如前所述，电子装置100可以实现在基站侧。在这种情况下，控制单元113还可以被配置为进行控制以将确定单元111所确定的上行传输模式通知给UE。
更具体地，控制单元113例如可以被配置为通过以下方式中的一项或更多项通知上行传输模式的配置和/或更换：通过RRC信令配置或重配置；通过媒体访问控制控制单元(MAC CE)半静态地配置；以及通过DCI动态地配置。
上行传输模式的配置和/或更换可以是以显式的方式通知的。例如，根据一个实施例，可以通过RRC信令、MAC CE或DCI中的信息来指示要采用的上行传输模式。例如，根据一个实施例，可以通过RRC参数txMode来指示UE采用的上行传输模式。根据另一个实施例，可以增加新的DCI格式，如DCI格式0_0_a，其不包含上行发送参数指示。
或者，上行传输模式的配置和/或更换可以是以隐式的方式通知的。例如，根据一个实施例，可以通过以下方式通知上行传输模式的配置和/或更换：当针对上行传输的配置信息中指示上行发送参数的值为空时，表示UE使用第三 模式；当配置信息中指示上行发送参数的值不为空时，表示UE使用第二模式。
针对上行传输的配置信息例如可以包括RRC信令、MAC CE或DCI中的信息。例如，如当调度上行数据的DCI中指示上行发送参数的值为空时，表示基站指示UE使用半开环模式；当调度上行数据的DCI中指示上行发送参数的值不为空时，标识基站指示UE使用闭环模式。又例如，TAC指令是一种MAC CE指令，当TAC MAC CE是缺省的，则表示采用半开环模式，而当TAC MAC CE有值时，表示采用闭环模式。
以DCI格式0_0为例进一步说明上行传输模式的指示方式。例如，当DCI格式0_0中的字段Modulation and coding scheme(调制编码方式)和TPC command for scheduled PUSCH(用于所调度的PUSCH的TPC命令)内容为空时，表示基站指示UE使用半开环模式；当字段Modulation and coding scheme和TPC command for scheduled PUSCH内容不为空时，表示基站指示UE使用闭环模式。
如前所述，电子装置100也可以实现在UE侧。在这种情况下，UE可以根据自身的能力(例如是否具有GNSS功能)来确定上行传输模式。例如，在具有GNSS功能的情况下，将第三模式(半开环模式)为默认模式，而当不具有GNSS功能的情况下，以第一模式(开环模式)为默认模式。
此外，控制单元113还可以被配置为进行控制以将与UE的能力有关的信息通知给基站，以便由基站侧进行上行传输模式的确定。
在前面对根据本发明实施例的电子装置的描述过程中，显然也公开了以下过程和方法。接下来，在不重复前面描述过的细节的情况下给出对根据本发明实施例的无线通信方法的说明。
如图2所示，根据一个实施例的无线通信方法包括根据UE的能力和/或UE与用于NTN通信的基站之间的信道情况，从分别对应于上行传输参数的不同获得方式的两个或更多个上行传输模式中确定用于UE的上行传输模式的步骤S210。该方法还包括基于所确定的上行传输模式进行UE到基站的上行传输的步骤S220。
如前所述，不同的上行传输模式例如可以包括开环模式、闭环模式或半开环模式。对于具有GNSS功能的UE，可以以半开环模式为默认模式。对于不具有GNSS功能的UE，可以以开环模式为默认模式。
上述方法可以实现在基站侧或UE侧。
在实现在基站的情况下，如图3所示，根据一个实施例的无线通信方法除了分别与S210和S220对应的步骤S310和S320之外，还可以包括将所确定的上行传输模式通知给UE的步骤S315。

[关于基站的应用示例]
图13是示出可以应用本公开内容的技术的gNB的示意性配置的示例的框图。gNB 2300包括多个天线2310以及基站设备2320。基站设备2320和每个天线2310可以经由射频(RF)线缆彼此连接。
天线2310中的每一个均包括单个或多个天线元件(诸如包括在多输入多输出(MIMO)天线中的多个天线元件)，并且用于基站设备2320发送和接收 无线信号。如图13所示，gNB 2300可以包括多个天线2310。例如，多个天线2310可以与gNB 2300使用的多个频带兼容。

控制器2321可以为例如CPU或DSP，并且操作基站设备2320的较高层的各种功能。例如，控制器2321根据由无线通信接口2325处理的信号中的数据来生成数据分组，并经由网络接口2323来传递所生成的分组。控制器2321可以对来自多个基带处理器的数据进行捆绑以生成捆绑分组，并传递所生成的捆绑分组。控制器2321可以具有执行如下控制的逻辑功能：该控制诸如为无线资源控制、无线承载控制、移动性管理、接纳控制和调度。该控制可以结合附近的gNB或核心网节点来执行。存储器2322包括RAM和ROM，并且存储由控制器2321执行的程序和各种类型的控制数据(诸如终端列表、传输功率数据以及调度数据)。
