Description

用于无线通信的电子设备和方法、存储介质
本申请要求于2017年8月10日提交中国专利局、申请号为201710680258.4、发明名称为“用于无线通信的电子设备和方法、存储介质”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
本发明的实施例总体上涉及无线通信领域，具体地涉及用于载波聚合(Carrier Aggregation,CA)的技术，更具体地涉及用于无线通信的电子设备和方法以及计算机可读存储介质。
背景技术
在载波聚合中，两个或更多个分量载波(Component Carrier，CC)被聚合以支持更宽的传输带宽。网络节点比如用户设备(User Equipment，UE)可以同时在一个或更多个分量载波上执行接收或发送。其中，被聚合的多个分量载波在频域上可以是连续的，也可以是非连续的。被聚合的分量载波包括主分量载波(Primary Component Carrier，PCC，下文中也简称为主载波)和辅分量载波(Secondary Component Carrier，SCC，下文中也简称为辅载波)。PCC例如可以用于初始链接的建立和重建，SCC可以用于提供额外的无线资源，可以被配置和激活。
另一方面，直通链路(sidelink)是网络节点之间进行直接通信的链路，比如D2D通信、V2V通信等，经由直通链路的通信可以没有网络控制节点的参与。在一些情况下，经由直通链路通信的网络节点可能位于网络控制节点的覆盖范围之外，从而无法可靠地接收来自网络控制节点的指令。在这种情况下，这些网络节点处于自主通信状态。

具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
<第一实施例>
现有的载波聚合解决方案均基于网络控制节点比如基站(在LTE系统中，例如为eNB)参与调度的方式，即，由基站进行载波聚合的各种行为比如相关测量、决策以及事件的触发的调度，在下文中将这种载波聚合的模式称为基站调度模式。并且，现在的载波聚合通信主要应用于网络控制端与网络节点之间的链路比如Uulink的场景中。
但是，如前所述，在网络节点与网络节点直接通信的sidelink场景下，网络节点之间的通信可以没有网络控制节点的参与，因此在使用载波聚合进行通信的情况下，现有的载波聚合的各种行为可能无法正确地执行。鉴于此，本实施例提出了直通链路中载波聚合的解决方案。在下 文中将没有基站参与的载波聚合模式称为用户自主选择模式。
在本申请中，网络控制节点指的是通信系统中用于实现通信活动的相关设置、控制、通信资源分配等功能的实体，比如蜂窝通信系统中的基站(例如，eNB或gNB)，C-RAN(Cloud-RAN/Centralized-RAN)结构下(可能不存在小区概念)的基带云设备，例如C-RAN架构下的彼此高速连通的BBU池中的任一BBU等。网络节点指的是通信系统中使用通信资源以实现其通信目的的实体，比如各种用户或用户设备(诸如具有蜂窝通信能力的移动终端、智能车辆、智能穿戴设备等)或者网络基础设施比如小小区基站等。
为了便于理解，图1和图2示出了V2V通信场景作为sidelink场景的示例。其中，基站作为网络控制节点，用户(或者对应的车辆，也可称为UE)作为网络节点。图1示出了用户在基站的覆盖范围之内(In-coverage，IC)的情形，图2示出了用户在基站的覆盖范围以外(Out-of-coverage，OOC)的情形。在下文中，将主要针对该sidelink场景进行描述，但是，应该理解，这并不是限制性的，仅是为了描述的方便，本申请的技术方案可以适当地应用于其他sidelink场景。
在OOC情形中执行载波聚合时，无法进行基于基站的调度。并且，由于用户的移动性，用户会在不同的载波覆盖范围之间频繁切换，导致载波聚合实施过程中的不稳定性，如图3所示。当然，还可能发生OOC情形与IC情形之间的相互切换。另外，辅载波的多样性、差异性以及测量依据的局限性会影响辅载波配置的准确性，进而影响载波聚合通信的可靠性。本申请提出的用于无线通信的电子设备用于解决或减轻这些问题中的一个或多个，并且不限于此。
图4示出了根据本申请的一个实施例的用于无线通信的电子设备100的功能模块框图。如图4所示，电子设备100包括：判断单元101，被配置为判断直通链路中可用分量载波的相关参数是否满足预定条件；以及配置单元102，被配置为在相关参数满足预定条件的情况下，将可用分量载波配置为用于直通链路中的载波聚合的辅载波。
其中，判断单元101和配置单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
电子设备100根据直通链路中可用分量载波的相关参数是否满足预 定条件来决定是否将其配置为辅载波。通过这种方式，电子设备100可以进行直通链路中用于载波聚合的辅载波的配置。电子设备100可以位于网络节点侧，也可以位于网络控制节点侧。本实施例将针对电子设备100位于网络节点侧的情形进行描述。
具体地，当电子设备100位于网络节点侧时，由网络节点进行SCC的配置，不需要网络控制节点的参与，尤其适用于OOC的场景，当然并不限于此，其也可以适用于IC的场景。
在进行辅载波的配置之前，还要进行主载波的确定。在IC的场景下，用于载波聚合的主载波可以由网络控制节点比如基站进行选择。在这样的示例中，网络控制节点向网络节点发送测量事件，网络节点对可用的CC的相关参数进行测量并上报给网络控制节点，网络控制节点根据上报的测量结果选择PCC，并为网络节点配置PCC。
示例性地，如图5所示，电子设备100还可以包括：测量单元103，被配置为对可用分量载波的相关参数进行测量；收发单元104，被配置为将测量结果提供给网络控制节点，以及从网络控制节点获取其基于测量结果选择的主载波的信息。其中，测量单元103和收发单元104可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。收发单元104的一部分还可以实现为通信接口或天线。
这里，在主载波和辅载波共用一个资源池的情况下，可用分量载波可以指的是资源池中的各个分量载波。而在单独设置针对主载波和辅载波的资源池的情况下，可用分量载波指的是主载波的资源池中的分量载波。
具体地，测量单元103可以对各个分量载波的通信质量的参数进行测量。通信质量的参数例如包括相应CC上的信号强度信息比如接收信号参考功率RSRP(Receiving Signal Reference Power)或接收信号强度指示RSSI(Receiving Signal Strength Indication)、信道质量指示CQI(Channel Quality Indicator)、信号干扰比SIR(Signal to Interference Ratio)、信道繁忙率CBR(Channel Busy Ratio)等。其中，网络控制节点例如可以选择通信质量最好的CC作为PCC。
此外，收发单元104还可以向网络控制节点提供网络节点的基本信息和负载测量结果，以使得网络控制节点判断是否进行载波聚合。基本 信息的提供发生在主载波的确定之前。换言之，sidelink通信双方向网络控制节点提供基本信息，以使得网络控制节点初步判断进行载波聚合的可行性和必要性。
例如，基本信息可以包括以下中的一个或多个：网络节点的类型比如是R14用户还是R15用户、网络节点的移动速度、网络节点的地理位置、网络节点的能力比如是否支持载波聚合或者信息处理能力等、网络节点收发链路情况、以及收发链路占用情况。此外，基本信息还可以包括有关网络节点的负载的概况，比如负载压力是否足够大、对传输速率的要求是否足够高，等等。当判断通信双方均能够进行载波聚合以及至少一方需要进行载波聚合时，网络控制节点确定要进行载波聚合并进行准备阶段。在该准备阶段中，网络控制节点如上所述进行PCC的选择。
为了便于理解，图6示出了在图1所示的场景下由基站进行PCC选择的示例中，基站与要进行载波聚合的用户之间的信息流程的示意图。首先，基站与用户1和用户2之间建立基本的无线资源控制(Radio Resource Control，RRC)连接。然后，用户1和用户2分别向基站上报其用户基本信息，基站基于这些信息判断用户是否有进行载波聚合的能力和需要。当判断有进行载波聚合的能力和需要时，基站向用户下发PCC选择测量配置，用户1和用户2相应地执行测量例如对CC的通信质量的测量并将测量结果上报给基站。应该理解，这里也可以由基站来执行测量操作比如对CC的通信质量的测量，而不需要用户的测量和上报。随后，基站根据事件测量结果来为用户1和用户2选择PCC，并为用户1和用户2配置PCC。应该理解，基站可以为用户1和用户2配置相同的PCC，也可以配置不同的PCC，即PCC对于通信双方而言可以是对称的，也可以是不对称的，这例如取决于双方所用的资源池和当前资源使用状态。
以上描述了由网络控制节点进行PCC的配置的示例，在另外的示例中，可以由网络节点、具体地由电子设备100的配置单元102根据各个可用分量载波的相关参数来确定用于直通链路中的载波聚合的主载波。
在该示例中，电子设备100例如用于直通链路一侧的第一网络节点，配置单元102与直通链路另一侧的第二网络节点协作执行载波聚合。应该理解，第一网络节点和第二网络节点仅是为了便于区分而命名的，并不代表任何顺序或其他意义，二者是对等的。在以下的描述中，将以第 一网络节点执行相关的决策操作的情形作为示例，但是，这并不是限制性的。
在第一网络节点和第二网络节点之间已建立了基本的sidelink连接。通过该sidelink连接，收发单元103可以在第一网络节点和第二网络节点之间共享相应网络节点的基本信息，即，收发单元103向第二网络节点发送第一网络节点的基本信息并接收第二网络节点的基本信息。有关基本信息的内容已在前文中给出，在此不再重复。配置单元102至少基于该基本信息来确定是否要执行载波聚合，例如基于该基本信息来确定第一网络节点和第二网络节点是否有执行载波聚合的能力和需要，并且在第一网络节点和第二网络节点均有执行载波聚合的能力且其中之一有执行载波聚合的需要的情况下，确定要执行载波聚合并进入载波聚合的准备阶段。
在该示例中，由于由网络节点自主地执行载波聚合操作，没有网络控制节点的参与，因此需要选择两个网络节点之一来进行必要的决策操作。作为一个示例，配置单元102基于所共享的网络节点的基本信息来确定由第一网络节点进行载波聚合中相关的决策操作，并且与第二网络节点协作达成一致。具体地，配置单元102可以通过比较第一网络接点的基本信息和第二网络节点的基本信息，例如比较两个网络节点的信息处理能力、负载状况等，选择处理能力较强、负载较轻的网络节点作为进行决策(包括触发)操作的网络节点，在本文中将以第一网络节点为决策网络节点作为示例。在各自进行了决策节点的选择之后，第一网络节点和第二网络节点可以交互各自的选择结果，并进行协商以达成一致。在这个过程中，第一网络节点和第二网络节点将进行信令的交互。
在选定了第一网络节点进行载波聚合相关的决策操作之后，第一网络节点的配置单元102对PCC进行配置。例如，第一网络节点和第二网络节点分别对可用CC的相关参数比如通信质量的参数进行自主测量，第二网络节点将测量结果报告给第一网络节点，第一网络节点的配置单元102基于第一网络节点的测量结果和第二网络节点所报告的测量结果来选择PCC，例如可以选择通信质量最好的CC作为PCC。类似地，通信质量的参数例如包括相应CC上的信号强度信息比如RSRP或RSSI、CQI、SIR、CBR等。
如果所选择的CC与基本sidelink通信所使用的CC是同一个，则 将基本sidelink通信所用的CC配置为PCC；否则，将所选择的CC配置为PCC，并在PCC上进行基本sidelink通信。考虑到实际信道状况、通信制式(比如TDD/FDD)等因素，对于第一网络节点和第二网络节点而言，PCC的选择可以是对称的也可以是不对称的，即，在sidelink载波聚合通信中使用的PCC可能多于一个。
为了便于理解，图7示出了在图1或图2所示的场景下由用户进行PCC选择的示例中，用户之间的信息流程的示意图。首先，用户1和用户2之间建立基本的sidelink连接，并通过该基本连接进行用户1和用户2的基本信息的共享。接着，用户1和用户2分别进行是否要进行载波聚合的判断并进行协商，例如，二者决定进行载波聚合并且由用户1执行相关的决策操作。随后，用户1和用户2分别进行PCC选择事件的测量，比如测量可用CC的通信质量的参数。用户2将测量结果报告给用户1，用户1基于二者的测量结果进行PCC的选择或重选，并通知用户2。
此外，在上述两种PCC的确定方式中，PCC的配置均可以是可变的，即可以进行PCC的重选。第一网络节点和第二网络节点可以周期性地对资源池中的载波进行测量，如果当前的PCC通信质量达不到门限值且资源池中其他可用载波的通信质量更好，例如RSRP值更小从而意味着有更多的空间供网络节点使用，则网络控制节点或者第一网络节点的配置单元102可以触发PCC切换事件。
另外，为了减轻网络节点的测量和选择压力，可以预先配置主载波选择范围。在配置主载波时，仅需要对该预先配置的范围内的CC进行测量和选择。
在采用如上之一的方式完成PCC的配置之后，由网络节点自主进行SCC的配置和激活。在PCC由网络控制节点配置的情况下，第一网络节点和第二网络节点首先如上所述地进行决策网络节点的协商确定，即相互共享基本信息并基于该信息来协商确定作为决策网络节点的网络节点。而在PCC由网络节点配置的情况下，由于已经选择出了决策网络节点，因此可以直接进行下述SCC的配置操作。可替选地，决策网络节点也是可以改变的，例如，在进行每一种决策操作之前或者在发生特定事件时，或者周期性地，由第一网络节点和第二网络节点基于基本信息以及当前的实时状态来进行决策网络节点的选择。为了描述的方便，不论 决策网络节点是否可变，均以第一网络节点为决策网络节点作为示例，但是应该理解，这并不是限制性的，并且决策网络节点的改变不会影响本申请的实施例的实施。
例如，配置单元102基于所共享的网络节点的基本信息对第一网络节点和第二网络节点要进行的对可用分量载波的测量操作进行配置，并且收发单元104获取相应网络节点所测量的可用分量载波的相关参数。
这里，在主载波和辅载波共用一个资源池的情况下，可用分量载波可以指的是资源池中除主载波之外的分量载波，例如，在网络控制节点配置PCC的情况下，可以通过对已经配置的分量载波比如已经被选择作为PCC的分量载波和被配置为SCC的分量载波进行标记来避免碰撞。另一方面，在单独设置针对主载波和辅载波的资源池的情况下，可用分量载波指的是辅载波的资源池中的分量载波。
配置单元102例如基于所共享的基本信息来配置如下之一的CC测量方式：由第一网络节点和第二网络节点之一来进行全部测量；由第一网络节点和第二网络节点分别进行针对本网络节点的测量；基于基本信息来确定第一网络节点和第二网络节点分别要完成测量的可用CC的比例。
例如，第一网络节点和第二网络节点的测量单元对基于基本信息确定的一定比例的可用CC进行周期性测量以获得可用CC的相关参数，并且第一网络节点的收发单元104从第二网络节点获取测量结果。在一个示例中，第二网络节点的测量结果仅在满足预定事件触发条件时才提供给收发单元104。其中，测量的周期例如由高层信令配置或被预配置。
一般地，优先选择通信质量更好、稳定性更好的CC配置为SCC。在一个示例中，可用CC的相关参数包括指示相应可用CC的通信质量的参数。即，网络节点对其可用CC的通信质量进行测量。例如，指示相应可用CC的通信质量的参数包括相应CC上的信号强度信息，该信号强度信息指示了相应CC的被占用情况。当信号强度越大时，说明相应分量载波被占用的程度越高，越不适合被配置为CC。因此，可以将预定条件设置为相应CC上的信号强度低于预定阈值，即，选择较为空闲的分量载波配置为SCC。例如，可以通过测量相邻载波偏移量、相邻载波频率的特定偏移、相邻载波的特定偏移量等来测量CC的通信质量。
在另一个示例中，可用CC的相关参数还可以包括指示负载情况的参数。实际上，负载情况也在一定程度上影响信号强度信息，二者共同用于衡量CC的通信质量。
此外，如前所述，在sidelink场景下，进行通信的网络节点可能处于高速移动的状态，导致网络节点在不同载波覆盖范围间频繁切换，进而导致载波聚合实施过程的不稳定。因此，还可以将可用CC的相关参数设置为包括指示相应可用分量载波的稳定度的参数，以保证载波聚合过程的稳定性。
示例性地，指示相应可用CC的稳定度的参数包括相应CC能够以满足要求的通信质量进行载波聚合通信的估计时长。其中，通信质量的要求例如由上层协议配置的通信质量门限确定或被预配置。
该估计时长例如是基于当前信道条件获得的。估计时长例如可以基于如下中的至少一个来确定：网络节点的移动速度、地理位置、收发链路占用率、可用CC的载波覆盖范围、载波信号强度等。该确定过程为估算过程，可以将估计时长与稳定性门限进行比较，并将比较结果作为决定该CC是否能够被配置为SCC的一个条件。例如，可以在CC的通信质量和稳定度均满足条件时，才将该CC配置为SCC。稳定性门限可以由基站配置、预先指定或者由用户指定。
此外，如果之前被配置为SCC的CC不再满足预定条件，在该CC没有被聚合的前提下，由配置单元102删除该CC的SCC配置。
为了便于理解，图8示出了在图1或图2所示的场景下由用户进行SCC配置的示例中，用户之间的信息流程的示意图。其中，仍以用户1执行载波聚合相关的决策操作的情形作为示例。首先，用户1根据用户1和用户2的用户基本信息来决定SCC配置测量事件的实施方式并通知用户2。接着，用户1和用户2根据所决定的SCC配置测量事件实施方式来进行测量，并且用户2将测量结果报告给用户1。用户1根据测量结果来决定SCC的配置，并通知用户2。
虽然图中未示出，但是在基站选择PCC的情形中，上述流程还应该包括如下步骤：在决定SCC配置测量事件的操作之前，在用户1和用户2之间共享各自的基本信息以及根据该基本信息确定要执行决策操作的用户。
以上完成了载波聚合的准备工作，此时可以对配置的SCC进行激活以执行载波聚合操作。例如，第一网络节点和第二网络节点的测量单元还可以对各自的负载进行周期性测量，配置单元102可以基于第一网络节点和第二网络节点的负载测量结果来执行辅载波的激活或去激活，换言之，执行是否进行载波聚合的判断以及相应的触发操作。其中，负载的测量配置可以由作为决策节点的网络节点作出和下发，也可以预先配置好。测量的周期例如由高层信令配置。
其中，对负载进行的测量例如可以包括对网络节点的数据缓存量或数据吞吐量中的至少之一进行的测量。
例如，配置单元102可以被配置为在满足如下之一的条件时执行辅载波的激活：第一网络节点和第二网络节点的负载均超过预定阈值；第一网络节点和第二网络节点中的特定网络节点的负载超过预定阈值；第一网络节点和第二网络节点之一的负载超过预定阈值。此外，还需要通知第二网络节点进行SCC的激活。
相应地，当配置单元102判断不满足上述激活条件时，如果当前有SCC正在被聚合，则配置单元102执行SCC去激活的操作，例如包括取消第一网络节点处的SCC的聚合以及通知第二网络节点执行去激活操作；否则继续正常的通信。因此，配置单元102还可以被配置为生成关于SCC的激活或去激活的指示信息，以通知第二网络节点。
其中，关于辅载波激活的条件的判断可以由第一网络节点和第二网络节点分别完成，并由第一网络节点对结果进行综合，也可以由第二网络节点将负载测量结果上报给第一网络节点并由第一网络节点根据二者的负载测量结果统一进行判断。
为了便于理解，图9示出了在图1或图2所示的场景下由用户进行SCC激活的示例中，用户之间的信息流程的示意图，其中，仍以用户1为决策网络节点作为示例。首先，用户1和用户2分别进行通信负载的测量，例如，该测量是周期性的。其次，基于负载的测量结果进行是否需要载波聚合的判断，如上所述，该判断可以由用户1作出，也可以由用户1和用户2联合作出。最后，基于该判断的结果进行SCC的激活或去激活。
综上所述，根据该实施例的电子设备100可以实现直通链路中的载 波聚合操作，通过使得通信的网络节点进行协作来代替网络控制节点的调度功能，可以使得在OOC场景下也能够进行直通链路中的载波聚合。可以理解，本申请所提出的sidelink下的载波聚合的技术可以应用于当前的4G通信系统、未来的5G通信系统以及采用可能出现的更先进的技术的通信系统。
<第二实施例>
在本实施例中将描述电子设备100位于网络控制节点侧的示例。根据该示例，将由网络控制节点来进行PCC和SCC的配置，即，由网络控制节点执行载波聚合的相关操作的网络控制节点进行调度的模式，适用于IC场景。
在这种模式下，网络控制节点如前所述地进行PCC的选择和配置，并且通过PCC周期性地向网络节点下发测量事件，测量的周期例如由高层信令配置。网络节点对各自可用的CC进行测量操作，例如测量各个可用CC的通信质量的参数。类似地，指示可用CC的通信质量的参数可以包括相应CC上的信号强度信息。例如，可以通过测量相邻载波偏移量、相邻载波频率的特定偏移、相邻载波的特定偏移量等来测量CC的通信质量。此外，网络节点还对相应CC可用于载波聚合的时长来进行估计，并将估计的时长作为稳定度的参数提供给网络控制节点。例如，估计时长可以基于如下中的至少一个确定：网络节点的移动速度、地理位置、收发链路占用率、可用分量载波的载波覆盖范围、载波信号强度。
网络节点将测量结果上报给网络控制节点，网络控制节点根据测量结果进行SCC的配置，例如，将满足预定条件的CC配置为SCC，并且删除已经被配置为SCC但不再满足预定条件且没有被聚合的CC的SCC配置。示例性地，当CC的通信质量高于预定值且稳定度高于预定稳定度时，认为该CC满足预定条件从而能够被配置为SCC。此外，网络节点也可以仅将满足触发条件的测量结果上报给网络控制节点。该触发条件可以预先设置。
此外，还可以设置为网络控制节点向网络节点下发测量配置，网络节点根据该测量配置进行可用CC的测量，并根据测量结果自主选择SCC。其中，网络节点可以如第一实施例中所述地基于基本信息确定决 策网络节点并由决策网络节点来选择SCC。或者，网络节点可以分别自主选择SCC。随后，网络节点将SCC的选择结果上报给网络控制节点，网络控制节点根据网络节点上报的SCC选择结果来进行SCC配置。
在其他示例中，也可以由网络控制节点进行可用CC的测量并根据测量结果为网络节点配置SCC，从而减轻网络节点的处理负荷和减小信令开销。
仍以图1所示的场景为例，图10和图11分别示出了基站调度模式下SCC的配置的信息流程。其中，图10示出了用户1和用户2将满足触发条件的测量结果上报给基站的示例，图11示出了用户1和用户2分别根据测量结果自主选择SCC并将选择结果上报给基站的示例。应该理解，这些信息流程不是限制性的。
在该模式下，网络控制节点可以向网络节点下发负载测量配置，网络节点周期性地进行通信负载的测量，并将满足触发条件的测量结果上报至网络控制节点。其中，测量的周期和触发条件例如由高层信令配置。网络控制节点根据上报的负载测量结果来决定是否激活SCC。或者，网络节点也可以根据负载的测量结果自主地决定是否激活SCC，这可以通过网络节点之间的协作来完成，例如只要一侧的网络节点的负载满足激活条件则可以激活SCC。
仍以图1所示的场景为例，图12示出了基站调度模式下SCC的激活的信息流程的示例。在该示例中，用户1和用户2上报满足触发条件的测量结果，基站根据这些测量结果来决定是否激活SCC。当然，用户1和用户2也可以上报所有测量结果。
综上所述，根据该实施例的电子设备100可以实现直通链路中的载波聚合操作。
<第三实施例>
如前所述，由于网络节点的移动，可能发生OCC场景与IC场景之间的相互切换，如图13和14所示。其中，图13中示出了OOC场景向IC场景的切换，图14中示出了IC场景向OOC场景的切换。
在第一网络节点和第二网络节点当前处于OOC的情况下，电子设 备100的判断单元101还可以被配置为判断第一网络节点和第二网络节点是否移动到网络控制节点的覆盖范围内，并且在判断为是的情况下，配置单元102与第二网络节点协商是否将载波聚合中相关的决策操作转移至网络控制节点，在判断为否的情况下，继续当前的载波聚合操作。换言之，在发生OOC至IC的切换时，由通信双方协商决定是否将载波聚合模式由网络节点自主选择模式切换至由网络控制节点进行调度的模式。例如，第一网络节点与第二网络节点基于网络节点的基本信息来作出该决定。
注意，本实施例中所述的网络控制节点进行调度的模式可以为第二实施例中所述的网络控制节点配置PCC和SCC的模式，也可以是第一实施例中所述的网络控制节点配置PCC而网络节点配置SCC的模式。
在决定要进行模式切换的情况下，收发单元104将第一网络节点和第二网络节点的基本信息和载波使用状况信息以及当前载波聚合的状态信息提供给网络控制节点。这样，网络控制节点可以基于这些信息来继续载波聚合操作。
为了便于理解，图15示出了在图13所示的场景下，由用户自主选择模式切换到基站调度模式的情况下，基站和用户之间的信息流程的示意图。其中，用户1和用户2正在进行载波聚合通信。用户1和用户2检测到完成从OOC至IC的切换，二者共同判决是否要进行载波聚合模式的切换。当决定要进行切换时，用户1和用户2可以分别向基站上报各自的基本信息。此外，用户1和用户2还可以向基站上报各自的载波使用状况以及当前载波聚合的状态信息。随后，基站分别与用户1和用户2建立基本的RRC连接，并切换至基站调度模式下的载波聚合。
另一方面，在第一网络节点和第二网络节点当前处于IC并且采用了网络控制节点调度模式的情况下，判断单元101还可以被配置为判断第一网络节点和第二网络节点是否移动到网络控制节点的覆盖范围外，并且在判断为是的情况下，与第二网络节点协作执行载波聚合，即切换到网络节点自主选择模式。
为了便于理解，图16示出了在图14所示的场景下，由基站调度模式切换到用户自主选择模式的情况下，基站和用户之间的信息流程的示意图。其中，用户1和用户2正在执行基站调度模式下的载波聚合通信。 用户1和用户2检测到完成从IC至OOC的切换，从而判决需要进行载波聚合模式的切换。用户1和用户2例如通过共享基本信息、进行决策网络节点的选择等操作来进行协作，从而切换到用户自主选择模式下的载波聚合。
本实施例提供了sidelink场景下在不同模式切换时载波聚合的实现，保证了载波聚合的持续正常进行。
<第四实施例>
本实施例将针对sidelink场景下的多播或广播方式中的载波聚合进行描述。参照图4和图5，配置单元102还可以被配置为生成关于载波聚合中所用的主载波和辅载波的相关信息，以广播至其他网络节点。例如，收发单元104可以经由物理直通链路广播信道(Physical sidelink broadcast channel，PSBCH)来发送该广播消息。例如，该相关信息可以以系统信息块(System Information Block，SIB)的形式被广播。相关信息可以包括以下中的一个或多个：主载波和辅载波的载波频率、载波序号、同步信息、资源池分配、优先级。
例如，可以采用SIB21来广播该相关信息。SIB21中包括v2x-InterFreqInfoList指令，该指令中包括用户可使用的载波信息(参数序号为0对应的是主载波，其他序号分别对应一个辅载波)、资源池(V2X-CommTxPoolNormalCcommon/Exceptional)和资源Zone的设置(ZoneConfig)、载波频率、同步信息、优先级等。此外，载波间调度资源分配也可以依据上述对应序号来进行，例如，DCI-5A中的CIF＝1对应第一条目的载波，以此类推。
此外，当电子设备100所在的网络节点作为接收广播信息的网络节点时，配置单元102还可以被配置为基于来自其他网络节点的关于载波聚合中所用的主载波和辅载波的广播信息，来确定是否进行载波聚合或者载波聚合的具体方式，比如对哪些载波进行载波聚合。
其中，其他网络节点广播的内容可能包括上述相关信息以及消息内容等。网络节点定期在其可使用载波频段上进行监听，当接收到其他网络节点的广播/多播信号之后，判断是否需要监听该消息，若判断结果为是，则依据该广播信息进行载波聚合。
其中，各个网络节点根据上层配置的针对该网络节点的V2X-CommRXinterestedFreqList/V2X-CommTxFreqList来确定在收发过程中是否能够使用多个载波。例如，配置单元102可以根据上层配置的V2X-CommRXinterestedFreqList参数来解析广播信息，解析之后获得可能聚合载波的频率、资源池、同步信息、优先级等信息。
图17示出了利用sidelink进行或多播或广播的场景的一个应用示例。其中，以用户作为网络节点的示例。用户1至用户6均处在基站覆盖范围之外，因此以用户自主选择模式进行Sidelink通信。其中用户1准备向其他用户发送一组大数据量的消息内容，并要求各用户在一定时间内接收并处理该消息内容。用户1发出请求，希望以载波聚合的方式传输此组消息内容。
首先，用户1根据自身的基本信息、周围可用载波情况等，采用主载波以及辅载波选择方法选择出最适合用户1用来进行载波聚合的主载波以及辅载波，分别命名为CC0，CC1/2/3……。并且，依据用户的基本信息、所选载波情况以及消息内容，为载波聚合操作设定同步信息等。
接着，用户1在PSBCH上以SIB21的形式将用于载波聚合的载波的相关信息广播出去。用户1可以以一定频率重复广播此消息，以使得尽可能多的用户能够收到该消息，其中，广播的频率可以由高层信令配置。
用户2至用户6在PSBCH上持续进行监听。例如，用户2没有被配置多重载波使用的信息，因此无法进行载波聚合以响应用户1的请求。用户3被配置了多重载波使用的信息，但其接收并解析广播信息后得知用户1所选载波对用户3来说并不可用或正在被占用，因此无法进行载波聚合以响应用户1的请求。用户4被配置了多重载波使用的信息并成功解析广播信息，但用户4判定用户1所发送消息内容对用户4而言无用，因此判定不响应用户1的请求。用户5和用户6被配置了多重载波使用的信息并成功解析了广播信息，判定响应用户1的请求，即，依据广播消息在指定载波上进行监听，按照同步消息在多个载波上进行通信，从而实现广播方式下的载波聚合。应该理解，图17仅给出了广播/多播形式下的载波聚合的一个示例，并不是限制性的。
<第五实施例>
在本实施例中，将给出直通链路场景下的载波聚合的几个应用示例，应该理解，这些应用示例均是示例性的，并非限制性的。
第一示例
在该示例中，直通链路存在于车队(Plantooning)通信场景下的车队成员之间。如图18所示，车队中有成员1作为车头，成员2/3作为车队成员。在车队行驶场景下用户的通信有着数据量大、时延要求低以及准确性要求高等特点，载波聚合是应对上述需求的有效办法。该场景中的载波聚合为用户自主选择模式下的载波聚合。
例如，用户依据用户的基本信息、通信负载等因素做出判决需要与其他用户进行载波聚合通信。用户彼此之间通过基本通信链路交换各自的基本信息。以用户1和用户2为例，当用户1接收到用户2的基本信息后与用户1的基本信息进行比较，提议由用户1来进行载波聚合的后续决策操作，并将该提议作为请求发送给用户2。用户2接收到用户1的请求后与用户2做出的判决结果进行比较，若结果一致则反馈同意，若不一致则反馈不同意并提出新的请求发送给用户1，直至双方达成一致。在此，假定双方协定用户1进行后续决策操作，即用户1作为决策网络节点。
随后，用户1向用户2发送载波测量配置消息，要求用户2测量用户2可用分量载波的相关参数，同时用户1也将对用户1可用的分量载波的相关参数进行测量。用户2完成测量后将结果上报给用户1。用户1接收到用户2的上报后结合用户1的测量结果，例如依照前述实施例中所述的载波选择/配置规则，确定用于与用户2进行载波聚合的合适载波(包括一个主载波和一个或多个辅载波)，并将结果告知用户2。用户2依据接收到的用户1发送的载波信息，并依据同步信息等，在约定时间和频率上进行载波聚合通信。用户1与其他用户可以类似地进行载波聚合操作，在此不再赘述。
第二示例
该示例中示出了载波聚合通信中主载波/辅载波的变换机制。如图19中所示，用户1与用户2正在进行载波聚合通信，其中CC0是主载波，CC1和CC2是被聚合进行通信的辅载波。CC3和CC4是没有参与载波 聚合通信的其他载波。随着用户的移动或通信条件的改变等因素，用户间用于载波聚合的载波可能会发生调整。
例如，如前所述，用户周期性地对通信负载进行评测。如果某时刻用户判定通信负载较低，则用户可以做出判决去激活一个辅载波CC2从而提高频谱利用率。其中，该用户可以为被选择为决策网络节点的用户，比如假定为用户1。用户1告知另一用户用户2要被去激活的载波CC2的基本信息，包括载波频率、同步信息等。用户2依据该信息去激活载波CC2，在保证通信质量的前提下减轻频谱资源浪费。
此外，用户周期性对可用载波进行测量(例如以前文所述的方式)，并且由决策用户用户1判决被测载波是否适合用来聚合并以此决定是否配置其为SCC。若用户1判断CC2的条件已经不合适作为SCC，而与此同时CC3更适合作为SCC，则用户1做出判决删除CC2的辅载波配置，而将CC3配置为辅载波。
用户还可以周期性地对主载波CC0进行测量(例如以前文所述的方式)，若某一时刻用户1判断现有主载波CC0已经达不到作为主载波的通信要求，而此时载波CC4可以满足作为主载波的条件，则用户1判决进行主载波切换，并告知另一用户用户2相关的主载波切换信息，以保证载波聚合通信的质量。
第三示例
该示例示出了用户自主选择模式下主载波的非对称配置的情形。在用户自主选择模式下，考虑到通信双方所处的通信环境以及条件不同，载波聚合的主载波的选择可能是非对称的。如前所述，影响主载波选择的因素包括用户的基本信息。可以理解，尤其在不同用户所处资源池不同的情况下，通信双方在分别作为接收方/发射方的时候有可能配置不同的主载波。
用户在共享用户基本信息时，可以分别独立判决是否可与对方用户使用相同的资源池。例如，用户1的发送资源池是否可以满足用户2用于接收的资源使用要求。用户1的接收资源池是否可以满足用户2用于发送的资源使用要求。若上述条件均满足，则可以考虑使用统一的资源池，进而配置对称的主载波，否则可以考虑非对称形式的主载波。通信双方分别进行判决，判决结果作为主载波选择的参考依据之一。
第四示例
在该示例中，至少一部分可用分量载波位于未授权频段，测量单元103可以通过未授权频段上的频谱感知来对该至少一部分可用分量载波进行测量。
在未来的载波聚合实施中，不可避免的一点就是利用未授权频段作为辅载波进行聚合，以获得更大的通信带宽。未授权频段通信具有功率小、覆盖范围小的特点，因此该频段更适合于Sidelink场景下用户之间近距离的载波聚合，尤其是在用户自主选择模式下。例如，授权频段下的主载波作为控制载波，而未授权频段的辅载波作为聚合载波来提供额外的无线资源。
例如，用户按照LTE-A场景下载波聚合方式配置主载波，基站或用户在未授权频段上进行感知，通过RSRP等信号强度参数获知未授权频段的使用情况(即，通信质量的指示)。基站或用户依据未授权频段的配置标准，例如优先将RSRP更小的未授权频段配置为SCC。基站或用户基于正在通信的载波上的负载情况判定是否触发SCC的激活事件，以在负载满足触发条件的情况下进行载波聚合。
应该理解，在未授权频段进行的载波聚合并不与传统LTE-A中进行的载波聚合相矛盾，同一个主载波可同时聚合授权频段内的载波以及非授权频段内的载波。具体的载波聚合方式可以根据实际通信情况和载波质量来决定。
此外，在进行载波激活从而实施载波聚合的过程中，授权频段内载波与未授权频段内载波的触发门限可能是不同的，这是因为，未授权频段内可用带宽较大，信道质量等与LTE-A场景下聚合的载波有差距。因此，在选择辅载波进行激活时，应充分比对两种频段内的辅载波，并依据实际情况选择用于聚合的辅载波。
第五示例
在该示例中，用于载波聚合的主载波以及/或者辅载波的至少一部分可以以毫米波形式传输。随着通信技术的发展以及频谱资源需求的增加，为了充分利用频谱资源，未来可能将使用毫米波技术在更高的频段上进行无线通信。毫米波技术将成为5G通信中的重要技术。如上所述，在sidelink的载波聚合中，可以采用毫米波波段的分量载波作为主载波，也 可以采用毫米波波段的分量载波作为辅载波或辅载波的一部分。因此，正常条件下的电磁波传输与毫米波的传输可能会存在共存、干扰、调制解调、抑制等情况。
在这种情况下，基站或用户将收到两个频段内的消息，例如可以针对不同波长的载波进行解调工作，使其可以共存以及协同传输消息，以此获得更大的通信带宽。应该注意，在载波聚合过程中，在每个载波上的测量、配置等行为都是独立完成的，因此对于使用不同波长的电磁波的用户来说，没有必要考虑其协同操作，只需考虑将其结果解调成兼容性好的表达形式，以使得基站或用户能够完整地了解载波聚合的相关情况。
此外，在使用毫米波作为载波聚合的辅载波的情况下，其配置、激活、去激活等等操作的细节都有别于LTE-A场景下的载波聚合，因此需要针对毫米波的特点来指定相应的判决门限。
<第六实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
图20示出了根据本申请的一个实施例的用于无线通信的方法的流程图。该方法包括：判断直通链路中可用分量载波的相关参数是否满足预定条件(S12)；以及在该相关参数满足预定条件的情况下，将可用分量载波配置为用于直通链路中的载波聚合的辅载波(S13)。
如图20中的虚线框所示，上述方法还可以包括如下步骤S11：根据各个可用分量载波的相关参数来确定用于所直通链路中的载波聚合的主载波。例如，在一些情况下，可以基于可用分量载波的测量结果分别为第一网络节点和第二网络节点确定不同的主载波。
其中，可用分量载波的相关参数包括指示相应可用分量载波的通信质量的参数。指示相应可用分量载波的通信质量的参数例如包括相应分量载波上的信号强度信息。预定条件可以设置为相应分量载波上的信号强度低于预定阈值。
例如，可用分量载波的相关参数还包括指示相应可用分量载波的稳定度的参数。指示相应可用分量载波的稳定度的参数包括相应可用分量载波能够以满足要求的通信质量进行载波聚合通信的估计时长。估计时长可以基于如下中的至少一个确定：网络节点的移动速度、地理位置、收发链路占用率、可用分量载波的载波覆盖范围、载波信号强度。
在一个示例中，上述方法由直通链路一侧的第一网络节点执行，第一网络节点与直通链路另一侧的第二网络节点协作执行上述载波聚合。
第一网络节点和第二网络节点共享相应网络节点的基本信息，至少基于该基本信息确定是否要执行载波聚合，其中，基本信息包括如下中的一个或多个：网络节点的类型、网络节点的移动速度、网络节点的地理位置、网络节点的能力、网络节点收发链路情况、以及收发链路占用情况。
在一个示例中，基于所共享的网络节点的基本信息，确定由第一网络节点进行载波聚合中相关的决策操作，并与第二网络节点协作达成一致。
可以基于所共享的网络节点的基本信息对第一网络节点和第二网络节点要进行的对可用分量载波的测量操作进行配置，并获取相应网络节点所测量的可用分量载波的相关参数。
第一网络节点和第二网络节点对基于基本信息确定的一定比例的可用分量载波进行周期性测量以获得可用分量载波的相关参数，并且第二网络节点将其测量结果提供给第一网络节点。示例性地，第二网络节点的测量结果可以在满足预定事件触发条件时提供给第一网络节点。
第一网络节点和第二网络节点还对各自的负载进行周期性测量，基于第一网络节点和第二网络节点的负载测量结果来执行辅载波的激活或去激活。
例如，在满足如下之一的条件时执行辅载波的激活：第一网络节点 和第二网络节点的负载均超过预定阈值；第一网络节点和第二网络节点中的特定网络节点的负载超过预定阈值；第一网络节点和第二网络节点之一的负载超过预定阈值。
第一网络节点还生成关于辅载波的激活或去激活的指示信息，以通知第二网络节点。
在一个示例中，第一网络节点生成关于载波聚合中所用的主载波和辅载波的相关信息，以广播至其他网络节点。该相关信息可以以系统信息块的形式在物理直通链路广播信道中进行广播，相关信息可以包括以下中的一个或多个：主载波和辅载波的载波频率、载波序号、同步信息、资源池分配、优先级。
相应地，其他网络节点可以基于来自第一网络节点的关于载波聚合中所用的主载波和辅载波的广播信息，来确定是否进行载波聚合或者载波聚合的具体方式。
在另一个示例中，第一网络节点和第二网络节点可以对可用分量载波的相关参数进行测量并将测量结果提供给网络控制节点，以及从网络控制节点获取其基于测量结果选择的主载波的信息。此外，第一网络节点和第二网络节点还可以向网络控制节点提供各自网络节点的基本信息和负载测量结果，以使得网络控制节点判断是否进行载波聚合。
第一网络节点和第二网络节点还可以分别对可用分量载波的相关参数进行周期性测量以进行步骤S12的判断和步骤S13的辅载波的配置。
在一个示例中，用于所述主载波的资源池与用于所述辅载波的资源池被设置为彼此相同。当然，也可以配置为彼此不同。
为了避免碰撞，还可以对被选择为主载波的分量载波和被配置为辅载波的分量载波进行标记。
在另一个示例中，还可以判断第一网络节点和第二网络节点是否由网络控制节点的覆盖范围外移动到网络控制节点的覆盖范围内，并且在判断为是的情况下，第一网络节点与第二网络节点协商是否将载波聚合中相关的决策操作转移至网络控制节点，在判断为否的情况下继续当前的载波聚合操作。例如，在要将载波聚合中相关的决策操作转移至网络控制节点的情况下，可以将第一网络节点和第二网络节点的基本信息和 载波使用状况信息以及当前载波聚合的状态信息提供给网络控制节点。
在又一个示例中，还可以判断第一网络节点和第二网络节点是否由网络控制节点的覆盖范围内移动到网络控制节点的覆盖范围外，并且在判断为是的情况下，与第二网络节点协作执行载波聚合。
其中，至少一部分可用分量载波可以位于未授权频段，例如可以通过未授权频段上的频谱感知对该至少一部分可用分量载波进行测量。用于载波聚合的主载波和/或辅载波的至少一部分可以以毫米波形式传输。
