Description

电子装置、信息处理设备和信息处理方法 技术领域
本公开一般涉及无线通信领域，更具体地，涉及用于基站侧的电子装置、信息处理设备和信息处理方法以及用于用户设备侧的电子装置、信息处理设备和信息处理方法。
背景技术
第三代合作伙伴项目(3GPP)希望定义一个全球统一的授权辅助接入(LAA)框架，使用未授权频段传输长期演进(LTE)数据。使用未授权频段的LAA设备不能避免与诸如无线保真(Wi-Fi)设备、雷达设备等其他通信设备以及其他运营商的LTE设备共存。
在LAA过程中，为了避免与其他设备发生冲突，用户设备可以在传输数据前进行载波侦听(LBT)，从而可能造成接收冲突。
LBT方案可以分为以下类别：
类别1(Cat 1)：不进行LBT；
类别2(Cat 2)：没有随机退避过程的LBT；
类别3(Cat 3)：使用大小固定的竞争窗口进行随机退避过程的LBT；以及
类别4(Cat 4)：使用大小可变的竞争窗口进行随机退避过程的LBT。
发明内容
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。

根据在一个实施例，提供一种用于用户设备侧的信息处理方法。该方法包括接收指示竞争窗口长度或者基于竞争窗口长度生成的随机退避计数器大小的信息的步骤，其中竞争窗口长度是基于至少一个用户设备在未授权频段上的上行传输的成功率而调整的。该方法还包括基于竞争窗口长度或者随机退避计数器大小采用竞争窗口长度可变的随机退避过程对未授权频段进行载波侦听的步骤。
根据本发明的实施例，通过根据上行传输的成功率调整用于载波侦听的竞争窗口长度，能够更好地避免利用未授权频段进行的上行传输时发生信道冲突的情况。

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基站侧的电子装置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包括获取单元111、调整单元113和控制单元115。需要指出，虽然附图中以功能块的形式示出了获取单元111、调整单元113和控制单元115，然而应理解，获取单元111、调整单元113和控制单元115的功能也可以由处理电路110作为一个整体来实现，而并不一定是通过处理电路110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110，然而电子装置100可以包括多个处理电路，并且可以将获取单元111、调整单元113和控制单元115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。
获取单元111被配置为获取关于至少一个用户设备在未授权频段上的上行传输的成功率的信息，其中该用户设备采用信道检测过程针对未授权频段进行载波侦听，其中该信道检测过程包括竞争窗口长度可变的随机退避过程(在下文中，将这种载波侦听简称为Cat4LBT)。
具体地，上行传输例如可以包括物理上行共享信道(PUSCH)传输。进一步地，所述上行传输可包括PUSCH上的数据传输。
调整单元113被配置为基于获取单元111所获取的用户设备在未授权频段上的上行传输的成功率的信息来调整用户设备的竞争窗口长度(Contention Window Size,下文中，“竞争窗口长度”也可以被简称为CWS)。
根据具体实施方式，获取单元111和调整单元113的处理可以是特定于用户设备(UE-specific)或者特定于小区(Cell-specific)的，可以是针对单 个用户设备进行的也可以是针对多个用户设备进行的。
根据一个实施例，由获取单元111获取的信息指示能够进行Cat4LBT的用户设备中的第一用户设备在先前上行传输突发(UL transmission burst)的至少一个子帧内的上行传输的成功率，其中第一用户设备在该至少一个子帧内被调度(scheduled)。并且调整单元113所进行的调整包括调整第一用户设备的竞争窗口长度。
传输突发的含义如下：传输突发是来自传输节点的连续传输，并且紧接在该连续传输之前和之后均没有来自该节点在同一载波上的传输。从用户设备的角度，上行传输突发是指来自用户设备的连续传输，并且紧接在该连续传输之前和之后均没有来自该用户设备在同一载波上的传输。应注意，虽然从用户设备的角度解释了上行传输突发，但也可以从基站的角度定义上行传输突发。另外，先前上行传输突发是指在要确定其竞争窗口长度的上行传输突发之前的上行传输突发，优选地为前一个上行传输突发。
具体地，上述至少一个子帧可以是第一用户设备在先前上行传输突发中被调度的子帧中的最后子帧。或者，上述至少一个子帧也可以包括第一用户设备在先前上行传输突发中被调度的全部子帧。然而，上述至少一个子帧内不限于此，而是可以包括先前上行传输突发中的子帧的任意子集，例如最后两个子帧、最后三个子帧、……最后n-1个子帧(其中n为先前上行传输突发中包含的子帧数量)等等。
接下来，参照图2至图4是说明针对单个用户设备进行上行传输成功率信息的获取和CWS调整的示例方式的示意图。
如图2所示，基站eNB服务的用户设备UE1、UE2、UE3、UE4中，针对每个用户设备单独地进行上行传输成功率信息的获取和CWS调整。
参照图3A和图3B说明针对单个用户设备(在示出的示例中为UE3)进行上行传输成功率信息的获取和CWS调整的第一示例方式。
在第一示例方式中，根据单个用户设备在先前上行传输突发中被调度的子帧中的最后子帧确定上行传输成功率。
如图3A所示，在突发(transmission burst)#1的四个子帧SF0-SF3中，子帧SF3中调度了UE3和UE4，也就是说，UE3在先前上行传输突发中被调度的子帧中的最后子帧为SF3，因此确定UE3在突发#1的子帧SF3中的例如PUSCH传输的成功率，并基于该成功进行CWS调整。
具体地，在基于单个子帧确定传输成功率的情况下，例如，在子帧中的PUSCH具有一个码字的情况下，成功率可以是0％(未接收到PUSCH)或100％(接收到PUSCH)；在子帧中的PUSCH具有两个码字的情况下，可以分别考虑每个码字的HARQ-ACK(混合自动重传请求-确认)值，而对于该子帧，成功率可以是0％(未接收到PUSCH)、50％(接收到PUSCH的一个码字)或100％(接收到PUSCH的两个码字)。
如图3B所示，在突发#1的四个子帧SF0-SF3中，子帧SF3中调度了UE1和UE2，子帧SF2中调度了UE3和UE4，也就是说，UE3在先前上行传输突发中被调度的子帧中的最后子帧为SF2，因此确定UE3在突发#1的子帧SF2中的例如PUSCH传输的成功率，并基于该成功进行CWS调整。
参照图4说明针对单个用户设备(在示出的示例中为UE3)进行上行传输成功率信息的获取和CWS调整的第二示例方式。
在第二示例方式中，根据单个用户设备在先前上行传输突发中被调度的全部子帧确定上行传输成功率。
如图4所示，在突发#1的四个子帧SF0-SF3中，子帧SF1和SF3中调度了UE2和UE3，而子帧SF0和SF2中未调度UE3，也就是说，UE3在先前上行传输突发中被调度的子帧包括SF1和SF3，因此确定UE3在突发#1的子帧SF1和SF3中的例如PUSCH传输的成功率，并基于该成功进行CWS调整。
具体地，在基于多个子帧确定传输成功率的情况下，也可以在分别考虑每个子帧的每个码字的HARQ-ACK值的情况下确定相应的传输成功率。
此外，根据另一个实施例，由获取单元111获取的信息指示能够进行Cat4LBT全部用户设备(例如上述示例中的UE1-UE4)在先前上行传输突发的至少一个子帧内的上行传输的成功率。需要指出，本发明的实施例也包括针对基站所服务的能够进行Cat4LBT多个(而不一定是全部)用户设备共同进行处理的方案。
具体地，上述至少一个子帧可以是先前上行传输突发的最后一个子帧。或者，上述至少一个子帧可以包括先前上行传输突发的全部子帧。然而，上述至少一个子帧内不限于此，而是可以包括先前上行传输突发中的子帧的任意子集，例如最后两个子帧、最后三个子帧、……最后n-1个子帧(其中n为先前上行传输突发中包含的子帧数量)等等。
接下来，参照图5至图7是说明针对多个用户设备进行上行传输成功率信息的获取和CWS调整的示例方式的示意图。
如图5所示，针对基站eNB服务的用户设备UE1、UE2、UE3、UE4共同地进行上行传输成功率信息的获取和CWS调整。
参照图6说明针对多个用户设备(在示出的示例中为UE1-UE4)进行上行传输成功率信息的获取和CWS调整的第一示例方式。
在第一示例方式中，根据先前上行传输突发的最后一个子帧确定上行传输成功率。
如图6所示，在突发#1的子帧SF3中，UE1、UE2和UE3被调度，因此例如可以获取UE1、UE2和UE3在突发#1的子帧SF3中的PUSCH的HARQ-ACK比例作为上行传输成功率。
参照图7说明针对多个用户设备(在示出的示例中为UE1-UE4)进行上行传输成功率信息的获取和CWS调整的第二示例方式。
在第二示例方式中，根据多个用户设备在先前上行传输突发中被调度的全部子帧确定上行传输成功率。
如图7所示，突发#1的子帧SF0中，UE1和UE2被调度；突发#1的子帧SF1中，UE2和UE3被调度；突发#1的子帧SF2中，UE3和UE4被调度；突发#1的子帧SF3中，UE1和UE3被调度。然而与具体被调度的用户设备无关地，根据突发#1的子帧SF0-SF3总体地确定上行传输成功率。
然而，如前所述，例如也可以根据子帧SF2和SF3来确定上行传输成功率，或者可以根据子帧SF1、SF2和SF3来确定上行传输成功率，等等。
接下来，说明调整单元113基于上行传输成功率对CWS进行调整的示例方式。
根据一个实施例，调整单元113被配置为在获取单元111所获取的传输成功率低于预定阈值的情况下，增大CWS。其中，上行传输成功率例如是通过上述示例实施方式获得的。相应地，根据获取上行传输成功率的不同方式，可以设置不同的预定阈值。
例如，在如前面提到的示例中那样，上行传输成功率为0％或100％的情况下(对应于在针对单个用户设备、单个子帧、并且子帧中包括单个码字的情况)，在上行传输成功率为0％的情况下例如可以增大CWS，在上行传输成功率为100％的情况下例如可以不改变CWS。换句话说，预定阈值实际 上可以被设置为0％至100％之间的任意值。又例如，上行传输成功率为0％、50％或100％的情况下：在上行传输成功率为0％的情况下例如可以增大CWS，在上行传输成功率为50％或100％的情况下例如可以不改变CWS(在这种情况下，预定阈值实际上可以是0％至50％之间的任意值)，或者，在上行传输成功率为0％或50％的情况下例如可以增大CWS，在上行传输成功率为100％的情况下例如可以不改变CWS(在这种情况下，预定阈值实际上可以是50％至100％之间的任意值)。
在根据多个用户设备的传输成功率并且/或者根据多个子帧的传输成功率调整CWS的情况下，可以设置相应的预定阈值，例如，可以将总体成功率阈值设置为20％(例如对应于相应PUSCH传输的HARQ-ACK值为NACK的比例为80％的情况)、25％、30％等。
另外，也可以设置多个阈值，例如在成功率低于第一阈值的情况下增大CWS，在成功率在第一阈值和第二阈值之间的情况下不改变CWS，在成功率高于第二阈值的情况下减小CWS。
此外，还可以想到多种根据预定阈值调整CWS的方式。
根据一个实施例，CWS值可以是从多个预定CWS值中选择的，并且，调整单元113所进行的调整可以包括：切换对预定竞争窗长度的选择。
进一步地，多个预定CWS值可以包括根据信道接入优先级而预先确定的多组预定竞争窗口长度。
图8列出了根据信道接入优先级预先确定的预定竞争窗口长度的示例。其中，信道接入优先级p分为4档，高优先级(优先级1为最高优先级)例如对应于对响应时间要求较高的业务，低优先级例如对应于对响应时间要求较低的业务。对于优先级1，CWS最小值为3，CWS最大值为7，并且可以取的值为3和7；对于优先级2，CWS最小值为7，CWS最大值为15，并且可以取的值为7和15；对于优先级2，CWS最小值为15，CWS最大值为63，并且可以取的值为15、31和63；对于优先级4，CWS最小值为15，CWS最大值为1023，并且可以取的值为15、31、63、127、255、511和1023。可以根据上述CWS值生成随机退避计数器的的大小，例如，当CWS取值为3时，所生成的随机退避计数器的大小例如可以是1、2或3。上述具体CWS值设置仅仅是示例性的而非限制性的，可以根据具体应用设置不同的CWS值。进一步地，当所述调整单元调整对应某一优先级的CWS时，同时调整其它优先级对应的CWS。调整的方式与本发明实施例提供的方式相同。 如当调大某一优先级对应的CWS时，同时调大其它优先级对应的CWS，反之亦然。
返回参照图1，控制单元115被配置为进行控制以将经调整的CWS或者基于经调整的CWS生成的随机退避计数器(random back off counter)大小(下文中，“随机退避计数器大小”也可以被简称为“计数器”(counter))通知给用户设备。
其中，在将经调整的CWS通知给用户设备的情况下，用户设备基于所通知的CWS来随机地生成随机退避计数器大小，以进行随机退避过程。另一方面，在将基于经调整的CWS生成的随机退避计数器大小通知给用户设备的情况下，用于设备所要采用的随机退避计数器大小由基站侧基于经调整的CWS随机生成。
需要指出的是，这里中所述的将经调整的CWS通知给用户设备可以包括将CWS的调整方式通知给用户设备，而不一定将具体的CWS值通知给用户设备。例如，如前面结合具体实施例说明的，在CWS选自多个预定CWS的情况下，基站侧可以例如将增大CWS的信息通知给用户设备，用户设备可以根据该指令在预定的CWS中选择长度大于当前CWS的新的CWS。
控制单元115例如可以进行控制以利用特定于用户设备的信道分别向各用设备通知CWS调整或相应随机退避计数器大小。特别地，在针对多个用户设备整体确定CWS调整并且将CWS调整通知给用户设备的情况下，也可以例如通过广播信道将CWS调整统一发送给多个用户设备。
此外，根据本发明实施例的CWS调整方案可以应用于利用多个未授权频段载波进行上行传输的情形。换句话说，用户设备可以利用上述实施例的方式对多个未授权频段载波(或多个未授权频段载波之一)进行载波监听并且利用多个未授权频段载波进行上行传输。在对这些实施例进行说明之前，首先对多载波传输的过程进行简要说明。
在利用多个未授权频段载波进行上行传输的情况下，可以采用以下方式之一对载波进行访问：
A方式：在未授权频段上各个载波的信道检测过程(如LBT)各自相互独立。根据不同的CWS的调整方式，A方式又可以分为A1方式和A2方式：
A1方式：针对载波中的每个分别进行CWS调整，并且针对每个载波分别生成随机退避计数器大小以用于相应载波的LBT；
A2方式：针对载波中的每个分别进行CWS调整，并且基于各载波的CWS中最大的一个CWS生成随机退避计数器大小，将该随机退避计数器大小用于每个载波的LBT；
B方式：将未授权频段上的载波包括主载波和辅载波，对于主载波进行Cat4LBT，而对于辅载波进行Cat2LBT。根据主载波上CWS调整方式的不同又可范围B1方式和B2方式：
B1方式：基于全部载波上的传输成功率确定主载波的CWS调整，以用于主载波的LBT；以及
B2方式：针对每个载波确定CWS调整，并基于其中最大的CWS生成用于主载波的LBT的随机退避计数器大小。
对应于上述A1方式，根据一个实施例，获取单元111和调整单元113分别被配置为针对未授权频段上的多个载波中的每个载波进行上行传输成功率的获取和对CWS的调整。并且，控制单元115被配置为将针对相应载波调整的竞争窗口长度或者基于经调整的竞争窗口长度而相应生成的随机退避计数器大小通知给用户设备，以用于相应载波。
对应于上述A2方式，根据一个实施例，获取单元111和调整单元113分别被配置为针对未授权频段上的多个载波中的每个载波进行上行传输成功率的获取和对CWS的调整。并且，控制单元115被配置为基于针对各载波调整的竞争窗口长度中的最大竞争窗口长度生成随机退避计数器大小，以及将基于最大竞争窗口长度生成的随机退避计数器大小通知给用户设备，以用于全部载波的载波监听。
对应于上述B1方式，根据一个实施例，获取单元111和调整单元113分别被配置为通过以下方式之一针对未授权频段上的多个载波中的主载波进行上行传输成功率的获取和对CWS的调整：根据第一用户设备在多个载波中的每个载波上在先前上行传输突发中被调度的子帧中的最后子帧来获取传输成功率信息，并且调整第一用户设备的用于主载波的竞争窗口长度；根据第一用户设备在多个载波中的每个载波上在先前上行传输突发中被调度的全部子帧来获取传输成功率信息，并且调整第一用户设备的用于主载波的竞争窗口长度；根据在多个载波中的每个载波上在先前上行传输突发中的最后子帧发生的所有上行传输(如PUSCH数据传输)来获取传输成功率信息进行主载波上的竞争窗口长度调整，并且调整后的竞争窗口长度适用于全部用户设备；根据全部用户设备在多个载波中的每个载波上在先前上行传输 突发中的全部子帧中发生的所有上行传输(如PUSCH数据传输)来获取传输成功率信息进行主载波上的竞争窗口长度调整，并且调整后的竞争窗口长度适用于全部用户设备。
对应于上述B2方式，根据一个实施例，获取单元111和调整单元113分别被配置为针对未授权频段上的多个载波中的每个载波进行上行传输成功率的获取和对CWS的调整。并且，控制单元115被配置为基于针对各载波调整的竞争窗口长度中的最大竞争窗口长度生成随机退避计数器大小，以及将基于最大竞争窗口长度生成的随机退避计数器大小通知给用户设备，以用于主载波的载波监听。
接下来，分别针对各个结合方案的实施例的示例方式进行说明。在下面的说明中，假设用户设备包括UE1、UE2和UE3，载波包括Carrier 1、Carrier 2和Carrier 3，并且与相应用户设备和相应载波对应的CWS调整如下表所示：

然后，针对每个用于设备，确定所要采用的CWS调整，其中，将UE1在每个载波上的CWS调整分别确定为CWS11、CWS21、CWS31；将UE2在每个载波上的CWS调整分别确定为CWS12、CWS22、CWS32；将UE3在每个载波上的CWS调整分别确定为CWS13、CWS23、CWS33；

然后，将UE1的用于每个载波的CWS调整分别确定为CWS11、CWS21、CWS31，基站根据CWS11、CWS21、CWS31中最大的一个生成counter，以作为UE1在每个载波上进行LBT的counter。对于U2和U3，以与UE1类似的方式生成counter。
(3)在采用B2的多载波访问方式，并且针对每个用户设备单独确定CWS调整的情况下：

然后，将UE1在每个载波上的CWS调整分别确定为CWS11、CWS21、CWS31，对于主载波，根据CWS11、CWS21、CWS31中最大的一个生成counter，并通知给UE1，对于副载波，可以进行Cat2LBT。对于UE2和UE3，情况类似。
(4)在采用A1的多载波访问方式，并且针对多个用户设备共同确定CWS调整的情况下：
首先，对于Carrier1，通过根据本发明实施例的针对多个用户设备共同确定CWS调整的方式确定CWS1(CWS1是UE1、UE2和UE3是共用的，即，CWS11＝CWS12＝CWS13＝CWS1)，类似地，对于Carrier 2确定CWS2(CWS21＝CWS22＝CWS23＝CWS2)，对于Carrier 3确定CWS3(CWS31＝CWS32＝CWS33＝CWS3)；
