具体实施方式
在下文中将结合附图对本公开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公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步 骤，而省略了与本公开关系不大的其它细节。
在具体描述本公开的实施例之前，应指出，本文中所提及的“直通链路通信”一般是指经由PC5接口进行的通信，并且包括至少车联网通信(Vehicle to Everything,V2X)、设备到设备通信(Device to Device,D2D)、机器类通信(Machine Type Communication,MTC)、无人机(Unmanned Aerial Vehicles,UAV)通信和载波聚合通信(Carrier Aggregation，CA)等中的一种或多种。还应指出，车联网通信(V2X)可以包括车辆间通信(Vehicle to Vehicle，V2V)、车辆到基础设施通信(Vehicle to Infrastructure,V2I)、车辆到网络通信(Vehicle to Network,V2N)和车辆到行人(Vehicle to Pedestrian,V2P)等等。特别地，V2I中的基础设施不仅包括传统的基站，还包括路边单元(Roadside Unit，RSU)。

[1-1.由用户设备自主选择资源的场景中的示例]
图1是示出根据本公开的实施例的无线通信系统中的基站侧的装置的配置示例的框图。该实施例对应于用户设备在基站的覆盖范围内(In-Coverage)的场景。
如图1所示，根据本实施例的装置100可包括确定单元102和控制单元104。
确定单元102可被配置成基于至少资源集合配置信息、物理信道信息和业务类型信息中的一个或多个，确定用于直通链路通信的一个或多个参数集的配置信息。
这里的参数集是指用于传输的基本参数配置，并且可以包括至少子载波间隔和循环前缀类型。优选地，参数集还可以包括子帧中的时隙数量、时隙中的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数量和帧中的时隙数量中的一个或多个。此外，参数集还可以包括可以相应推出的子帧中的OFDM符号数量、帧中的OFDM符号数量等一系列传输相关参数，在此不再一一列举。
应指出，参数集中所包括的例如子帧中的时隙数量、时隙中的OFDM符号数量、帧中的时隙数量等参数的配置都可以由子载波间隔和循环前缀类型的配置共同决定，因此，一个参数集中所包括的参数实际上与一对确定的“子载波间隔和循环前缀类型”的组合存在一一对应关系。换言之，在给定了一个参数集中的子载波间隔和循环前缀类型的情况下，也即相应地确定了该参数集中的其他参数。子载波间隔可以表示为Δf＝2 μ·15[kHz]，μ为整数，循环前缀类型可以包括常规型(normal)和扩展型(extended)，从而参数集中的其他参数也可以由参数μ和循环前缀类型来表示。因此，在对用户设备配置要使用的参数集时，可以仅将参数μ和循环前缀类型的指示信息通知给用户设备，从而可以减少信令开销和通信负荷，并且用户设备可以根据所接收到的参数μ的值和循环前缀类型相应地得到参数集中的传输相关参数。在以下描述参数集的配置示例时，为了便于说明，将通过给出参数μ的取值示例来表示可配置的参数集的示例。
资源集合配置信息可以包括例如资源池的配置信息(例如，资源池的划分情况)、载波的配置信息、带宽块(Bandwidth Part，BWP)的配置信息等与传输资源配置相关的信息，从而可以根据不同的资源集合配置所承载的业务内容而为其配置不同的参数集。
物理信道信息可以至少包括例如指示物理信道类型的信息。直通链路通信中包括三种类型的物理信道，即，物理直通链路控制信道(Physical Sidelink Control Channel，PSCCH)、物理直通链路共享信道(Physical Sidelink Shared Channel，PSSCH)和物理直通链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)，从而可以根据不同类型的物理信道所对应的频段、调制解调方式等多种因素为其配置不同的参数集。
作为示例而非限制，在NR的直通链路通信中，对于PBSCH，可以优选地选择μ的取值为-2、-1、0、1、2、3、4所对应的多个参数集，更优选地可以选择μ的取值为-1、0、1、2所对应的多个参数集，并且如果只选择唯一的参数集，则为了保持与传统LTE业务的兼容性，参数μ可以优选地设置为0。对于PSCCH，可以优选地选择μ的取值为0、1、2、3所对应的多个参数集，更优选地可以选择μ的取值为0、2所对应的多个参数集，并且如果只选择唯一的参数集，则为了保持与传统LTE业务的兼容性，参数μ可以优选地设置 为0。对于PSSCH，可以优选地选择μ的取值为-5、-4、-3、-2、-1、0、1、2所对应的多个参数集，更优选地可以选择μ的取值为-3、-2、-1、0、1、2所对应的多个参数集，并且如果只选择唯一的参数集，则为了保持与传统LTE业务的兼容性，参数μ可以优选地设置为0。
业务类型信息可以至少包括例如指示直通链路通信承载的业务是LTE业务还是NR业务的信息，从而可以根据LTE业务以及NR业务对通信性能的不同要求而配置不同的参数集。例如，在业务类型信息指示LTE业务的情况下，可以确定一个固定的参数集(例如，子载波间隔固定为15kHz，即，参数μ＝0)，而在业务类型信息指示NR业务的情况下，可以进一步结合其他因素来确定适合当前业务的多个参数集。这样，可以实现与传统LTE中的直通链路通信的兼容性。另外，在业务类型信息指示LTE业务和NR业务并存的情况下，为了保证兼容性，也可以考虑配置参数μ＝0(即，子载波间隔固定为15kHz)所对应的参数集。
应指出，尽管以上描述了基于资源集合配置信息、物理信道信息和业务类型信息中的一个或多个来确定一个或多个参数集，但是在资源集合配置与参数集配置彼此相关联的情况下，这种确定也可以理解为建立多个参数集与资源集合配置信息、物理信道信息和业务类型信息中的一个或多个之间的对应关系。换言之，在实际操作中，也可以基于所配置的参数集来确定资源集合配置信息、物理信道信息和业务类型信息中的一个或多个。
控制单元104可被配置成控制基站将所确定的一个或多个参数集的配置信息发送至用户设备，以使得用户设备可以基于这一个或多个参数集进行通信。
优选地，控制单元104可以进一步被配置成将一个或多个参数集的配置信息包括在高层信令(例如，无线资源控制(Radio Resource Control，RRC)层信令)中以便发送给用户设备。进一步优选地，如上所述，由于确定单元102可以建立资源集合配置信息与参数集的配置信息之间的对应关系，因此控制单元104也可以控制基站将一个或多个参数集的配置信息与资源集合配置信息相关联地发送至用户设备，以进行后续的资源选择和参数集选择。替选地，资源集合配置信息和参数集的配置信息也可以独立地发送至用户设备。
应指出，这里所确定并通知给用户设备的一个或多个参数集仅仅是作为候 选参数集，并且取决于资源选择模式是由基站进行调度还是由用户设备自主选择，可以由基站或用户设备从该候选参数集中选择直通链路通信要使用的具体参数集。
参照图1所描述的配置示例可以对应于由用户设备自主选择资源的场景，接下来将详细描述由基站进行资源调度的场景中的示例。
[1-2.由基站进行资源调度的场景中的示例]
图2是示出根据本公开的实施例的无线通信系统中的基站侧的装置的另一配置示例的框图。
如图2所示，根据该示例的装置200可以包括确定单元202、控制单元204和选择单元206。其中，确定单元202的功能配置示例与以上参照图1描述的确定单元102的功能配置示例基本上相同，在此不再赘述。接下来，将详细描述控制单元204和选择单元206的功能配置示例。
与以上参照图1描述的控制单元104类似地，控制单元204可以控制基站将确定单元202所确定的一个或多个参数集的配置信息通过例如RRC信令发送至用户设备。
选择单元206可以被配置成基于来自用户设备的与至少用户设备的移动速度、信道繁忙率(Channel Busy Ratio，CBR)、信道占用率(Channel Occupancy Ratio,CR)和直通链路通信的数据业务优先级中的一个或多个有关的信息，从一个或多个参数集中选择用于直通链路通信的参数集。
具体地，在用户设备可能处于高速移动的V2X场景中，较快的移动速度可能会导致信道条件的变化较大，因此需要用户设备将其移动速度(包括瞬时移动速度、一段时间内的平均移动速度等)上报给基站，以供基站为其选择更加合适的参数集用于直通链路通信。作为示例，速度越快，则选择越大的参数μ所对应的参数集。
作为示例，将参照图3描述简要描述由基站配置用户设备上报移动速度的信令交互过程。图3是示出根据本公开的实施例的由基站配置用户设备上报移动速度的信令交互过程的示例的流程图。
如图3所示，在步骤S301中，基站与用户设备建立初始连接(即，RRC_CONNECTED)，之后，基站可以在步骤S302中向用户设备下发测量配 置，要求用户设备周期性地或者响应于事件触发而上报其速度信息(包括瞬时速度、平均速度等)。
接下来，在步骤S303中，用户设备可以根据所接收到的测量配置，周期性地或者响应于事件触发而将其速度信息包括在测量报告中上报给基站。
返回参照图2，根据现有的测量配置，用户设备会将所测得的信道繁忙率和/或信道占用率周期性地或响应于事件触发而上报给基站，以供基站进行相关决策，从而基站侧的选择单元206还可以基于来自用户设备的信道繁忙率和/或信道占用率来选择适当的参数集。作为示例，信道繁忙率越大，即，信道越繁忙，则可以选择越大的参数μ所对应的参数集。信道占用率越大，即，信道占用程度越高，则可以选择越大的参数μ所对应的参数集。应指出，用户设备上报速度信息、信道繁忙率和信道占用率的周期以及触发事件可以相同或者也可以不同，本公开对此不做限制。
直通链路通信的数据业务优先级是指将通过该直通链路通信传输的数据业务的优先级，例如，可以由直通数据包优先级(ProSe Per-Packet Priority，PPPP)来指示，并且可以包括在来自用户设备的资源配置请求中。作为示例，直通链路通信的数据业务优先级越低，即，PPPP的值越大，则可以选择越大的参数μ所对应的参数集。
这里，应指出，选择单元206可以依据上述四个因素中的一个或多个来选择要使用的参数集，并且可以根据实际的应用场景而选择优先考虑哪个因素。例如，在V2X的应用场景中，用户设备的移动速度将作为主要考虑因素，其次是信道繁忙率，再其次是信道占用率，最后是直通链路通信的数据业务优先级。
此外，取代上述因素或者与上述因素一起，还可以根据用户设备的类型(例如，车辆、行人、移动中继、中继节点、车队成员、车队管理者等)、用户设备的信息处理能力(是否支持载波聚合、接收机的处理能力等等)、用户设备的行为、波束赋形相关信息等其他因素中的一个或多个来选择要使用的参数集。特别地，在无人机通信场景中，还可以进一步将以下因素纳入考虑，包括但不限于：用户设备的高度、海拔高度、风速、气压、温湿度、能见度等等。本领域技术人员可以根据本公开的原理和具体的应用场景来确定选择要使用的参数集时应考虑的因素，这里不再一一列举。
还应指出，上述来自用户设备的与至少用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个有关的信息可以是用户设备获得的原始信息，或者也可以是在用户设备侧对原始信息进行了预处理之后的信息。例如，用户设备可以根据所获得的移动速度、CBR、CR和PPPP中的一个或多个而确定优选的参数集选择范围，并将指示该参数集选择范围的信息上报给基站，从而基站可以结合实际的网络状况以及用户设备上报的参数集选择范围而为其选择最佳的参数集。
此外，优选地，在载波聚合通信(CA)的场景下，选择单元206可以进一步被配置成针对载波聚合通信中的每个成员载波来选择要使用的参数集。这是由于在CA场景中，不同的成员载波可能对应不同的业务类型，从而适用于不同的参数集配置。根据成员载波传输的内容及特点来选择对应的参数集配置，可以有效地提高载波聚合传输的效率。将在下文的应用场景示例中详细描述针对载波聚合通信的参数集配置和选择。
控制单元204可以进一步被配置成控制基站将选择单元206选择的参数集发送至用户设备，以由用户设备基于所选择的参数集而进行直通链路通信。
优选地，控制单元204可以将选择的参数集的相关信息包括在物理层信令中(具体地，例如sidelink grant)以发送至用户设备，从而用户设备可以通过对所接收到的物理层信令进行解码而获得该参数集，并利用该参数集进行直通链路通信。优选地，所选择的参数集也可以与基站为用户设备分配的用于直通链路通信的资源的配置信息相关联地通过sidelink grant被发送至用户设备。
应指出，以上参照图1至图3描述的基站侧的装置可以以芯片级来实现，或者也可以通过包括其它外部部件而以设备级来实现。例如，装置还可以工作为基站本身，并且包括通信单元(可选的，以虚线框示出)用于执行通信操作。通信单元可以包括一个或多个通信接口，例如PC5接口、X2接口、S1接口、Uu接口等等，以支持与不同设备(例如，V2I场景中的车辆、其他基站、传统用户设备等等)间的通信，这里不具体限制通信单元的实现形式。
此外，还应指出，以上所描述的基站侧的装置中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。在实际实现时，上述各个功能单元和模块可被实现为独立的物理实体，或者也可由单个实体(例如，处理器(CPU或DSP等)、集成电路等)来实现。
与上述基站侧的配置示例相对应的，下面将描述根据本公开的实施例的无线通信系统中的用户设备侧的配置示例。
<2.根据本公开的用户设备侧的配置示例>
图4是示出根据本公开的实施例的无线通信系统中的用户设备侧的装置的配置示例的框图。
如图4所示，根据该示例的装置400可以包括获取单元402和控制单元404。
获取单元402可以被配置成获取用于直通链路通信的一个或多个参数集。这一个或多个参数集是基于来自基站的配置信息而确定的或者是预先配置的，并且参数集包括至少子载波间隔和循环前缀类型。
具体来说，在用户设备处于基站覆盖范围内的情况下，可以由基站结合实际情况而实时地为用户设备配置一个或多个参数集，从而用户设备侧的获取单元402可以通过对从基站接收的包括一个或多个参数集的配置信息的高层信令(例如，RRC层信令)进行解码来获取这一个或多个参数集。由基站确定一个或多个参数集的具体过程可参见以上关于基站侧的实施例的描述，在此不再赘述。
另一方面，在用户设备处于基站覆盖范围外的情况下，用户设备无法接收到来自基站的配置信息，从而用户设备可以通过读取例如内部或外部的存储器获取所存储的默认参数集或上一次从基站接收到的配置信息获作为预先配置的一个或多个参数集。
控制单元404可以被配置成控制用户设备基于所获取的一个或多个参数集进行直通链路通信。
与上述基站侧的配置示例相对应的，下面也将分别针对由基站进行资源调度的场景和由用户设备自主选择资源的场景来进一步详细地描述用户设备侧的配置示例。
[2-1.由用户设备自主选择资源的场景中的示例]
图5是示出根据本公开的实施例的无线通信系统中的用户设备侧的装置的另一配置示例的框图。
如图5所示，根据该示例的装置500可以包括获取单元502、选择单元504和控制单元506。获取单元502的功能配置示例与以上参照图4描述的获取单元402的功能配置示例基本上相同，在此不再赘述。下面将仅详细描述选择单元504和控制单元506的功能配置示例。
选择单元504可被配置成基于与至少用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个有关的信息，从一个或多个参数集中选择用于直通链路通信的参数集。
优选地，选择单元504还可以进一步基于与用户设备的高度、用户设备的类型(例如，车辆、行人、移动中继、中继节点、车队成员、车队管理者等)、用户设备的信息处理能力(是否支持载波聚合、接收机的处理能力等等)、用户设备的行为、波束赋形相关信息等等其他因素中的一个或多个来选择要使用的参数集。
此外，优选地，选择单元504还可以基于涉及直通链路通信的其他设备的相关信息，从一个或多个参数集中选择用于直通链路通信的参数集。
作为示例，在V2X的自动排队驾驶(platooning)场景中，假设用户设备是车队管理者从而了解其他车队成员的基本信息，从而作为车队管理者的用户设备侧的选择单元504在选择用于直通链路通信的参数集时，还可以同时考虑其他车队成员的相关信息(例如，移动速度、待传输/接收数据业务类型、资源分配情况、信息处理能力等等)，以便选择适当的参数集。替选地，在上述由基站进行参数集选择的实施例中，用户设备也可以将这些信息汇总并转发至基站以由基站进行选择，在此不再详细描述。将在随后的应用场景示例中进一步详细描述自动排队驾驶场景中的参数集选择。
特别地，在直通链路通信是载波聚合通信的情况下，选择单元504可以进一步针对载波聚合通信中的每个成员载波，根据例如每个成员载波传输的内容和特点来选择每个成员载波所对应的参数集，以便提高载波聚合通信的效率。
此外，优选地，选择单元504可以进一步被配置成：在获取单元502所获取的一个或多个参数集为预先配置的情况下，还基于至少资源集合配置信息、物理信道信息和业务类型信息中的一个或多个，从一个或多个参数集中选择用于直通链路通信的参数集。
具体来说，在用户设备处于基站的覆盖范围之外从而无法接收到基站的实 时配置信息的场景中，获取单元502所获取的一个或多个参数集是默认的配置或先前从基站接收的配置，并未考虑当前的资源集合配置信息、物理信道信息和业务类型信息等等，从而选择单元504在从预先配置的一个或多个参数集中进行选择时，还可以同时将这些因素中的一个或多个纳入考虑，以选择适用于当前的直通链路通信的最佳参数集。
应指出，这里由用户设备侧的选择单元504从一个或多个参数集中选择要用于直通链路通信的参数集的处理与以上参照图2描述的由基站侧的选择单元206选择参数集的处理是基本上类似的，因此在此未详细描述的内容可参见以上相应位置的描述，在此不再赘述。
控制单元506可被配置成控制用户设备基于选择单元504所选择的参数集进行直通链路通信。
[2-2.由基站进行资源调度的场景中的示例]
图6是示出根据本公开的实施例的无线通信系统中的用户设备侧的装置的又一配置示例的框图。
如图6所示，根据该示例的装置600可以包括获取单元602和控制单元604。其中，获取单元602的功能配置示例与以上参照图4描述的获取单元402的功能配置示例基本上相同，在此不再赘述。下面将仅详细描述控制单元604的功能配置示例。
控制单元604可被配置成控制用户设备将与至少用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个有关的信息发送至基站，以由基站基于该信息从一个或多个参数集中选择用于直通链路通信的参数集。
具体地，控制单元604可以根据来自基站的测量配置而周期性地或响应于事件触发而将用户设备的速度相关信息(包括瞬时速度和平均速度等等)、测量得到的信道繁忙率和信道占用率中的一个或多个上报给基站。速度信息、信道繁忙率和信道占用率的上报周期和上报触发事件可以相同或者也可以不同，这里不做具体限定。
此外，控制单元604还获取待发送的通信业务的优先级信息(例如，PPPP)，并且可以将该优先级信息包括在例如资源配置请求中以上报给基站，从而基站 可以基于实际应用场景、根据上述因素中的一个或多个而选择适当的参数集，以兼顾系统稳定性和频谱效率。
控制单元604可以控制用户设备将用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个的原始信息直接发送至基站，或者也可以对这些原始信息进行预处理以确定用户设备的优选参数集选择范围，并且控制用户设备将该参数集选择范围的指示信息作为参数集配置请求而发送至基站。
除了上述因素之外，控制单元604还可以控制将与用户设备有关的其他信息或者用户设备获取到的其他信息(包括但不限于上述用户设备能力信息、用户设备类型信息、用户行为等等)发送至基站，以由基站针对不同的应用场景进行综合考虑以选择最佳的参数集。以V2X中的自动排队驾驶场景为例，在由基站侧来选择参数集的情况下，作为车队管理者的用户设备的控制单元604还可以将所掌握和汇总的其他车队成员的基本信息发送至基站，以由基站选择适合于车队成员间的直通链路通信的最佳参数集。
获取单元602可以通过对来自基站的物理层信令(例如，sidelink grant)进行解码来获取基站所选择的参数集，并且控制单元604可以控制用户设备基于所获取的参数集而进行直通链路通信。
应指出，这里参照图6描述的用户设备侧的装置的配置示例是与以上参照图2描述的基站侧的配置示例相对应的，因此在此未详细描述的内容可参见以上相应位置的描述，在此不再赘述。
[2-3.与其他设备交互参数集配置信息的示例]
图7是示出根据本公开的实施例的无线通信系统中的用户设备侧的装置的再一配置示例的框图。
如图7所示，根据该示例的装置700可以包括获取单元702、控制单元704和交互单元706。根据由用户设备还是由基站进行资源选择，这里描述的获取单元702和控制单元704分别具有与上述参照图5和图6描述的装置中包括的获取单元和控制单元基本上相同的功能配置示例，在此不再赘述。下面将仅详细描述交互单元706的功能配置示例。
交互单元706可以被配置成控制用户设备将所选择的参数集发送至与该 用户设备进行直通链路通信的一个或多个其他设备。
区别于现有技术中收发双方均基于固定的参数集配置进行直通链路通信，在本公开的实施例中，用于直通链路通信的参数集是可以动态灵活配置的，并且发送方将所选择的参数集通知给涉及直通链路通信的其他设备，以便收发双方可以同步通信所使用的参数集配置。
作为一种实现示例，交互单元706可以将所选择的参数集包括在直通链路控制信息(Sidelink Control Information，SCI)中，并以广播、单播和/或组播的方式将该SCI发送给其他设备，从而接收到SCI的其他设备可以通过解码信令而获得参数集的配置信息，并基于该参数集接收来自发送用户设备的信息。
类似地，在装置700所在的用户设备工作为接收设备的情况下，交互单元706也可以通过对来自其他设备的直通链路控制信息进行解码，获取其他设备用于直通链路通信的参数集，并由控制单元704基于所获取的其他设备的参数集而控制用户设备接收来自其他设备的信息。
图8是示出根据本公开的实施例的收发双方同步参数集配置的信令交互过程示例的流程图。
如图8所示，在步骤S801中，发送设备选择或确定直通链路通信要使用的参数集。具体地，发送设备可以通过执行上述选择单元504执行的选择处理来选择参数集，或者也可以通过解码来自基站的信息而确定基站选择的参数集。
接下来，在步骤S802中，发送设备将所选择/确定的参数集包括在SCI信令中以发送给接收设备。在步骤S803中，接收设备通过解码所接收到的SCI信令而获得发送设备将用于信息发送的参数集的配置信息。应指出，发送设备发送SCI信令所使用的参数集可以是收发双方预先约定配置的，或者也可以是随机选择的，从而接收设备可以相应地基于预先配置的参数集来接收SCI信令或者通过盲检测来接收SCI信令。
接下来，发送设备在步骤S804中使用所选择/确定的参数集对接收设备进行信息发送，并且接收设备在步骤S805中基于所解码的参数集的配置信息而接收来自发送设备的信息。
这里，应指出，这里参照图8描述的信令交互过程仅是为了说明收发双方的参数集配置同步过程，并且省略了与该过程无关的描述。此外，还应指出， 为了便于说明而参照图8所示的流程图以时间顺序描述了该同步过程，但是该时间顺序并不构成对本公开的限制。
还应指出，上述参照图4至图8描述的用户设备侧的装置可以以芯片级来实现，或者也可通过包括其它外部部件而以设备级来实现。例如，装置还可以工作为用户设备本身，并且包括通信单元(可选的，以虚线框示出)用于执行通信操作。通信单元可以包括一个或多个通信接口，例如PC5接口、Uu接口等等，以支持与不同设备(例如，车辆、互联网、基站等等)间的通信，这里不具体限制通信单元的实现形式。优选地，该装置还可以包括存储器(可选的，以虚线框示出)，用以存储默认的资源集合配置、参数集配置以及上一次从基站接收到的资源集合配置和参数集配置等等。
此外，还应指出，以上所描述的用户设备侧的装置中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。在实际实现时，上述各个功能单元和模块可被实现为独立的物理实体，或者也可由单个实体(例如，处理器(CPU或DSP等)、集成电路等)来实现。
还应指出，虽然以上参照附图所示的框图描述了本公开的装置实施例，但是这仅是示例而非限制。本领域技术人员可以根据本公开的原理对所示出的功能配置示例进行修改，例如，对其中的各个功能模块进行添加、删除、修改、组合等，并且所有这样的变型应认为均落入本公开的范围内。
另外，还应指出，尽管以上为了描述的清楚性而分开描述了在各个场景下的装置配置示例，但是这并不意味着各个实施例之间是互斥的。在实际实现时，可以根据本公开的原理而对各个实施例进行结合，并且这种结合当然应认为落入本公开的范围内。
为了有利于进一步理解本公开的技术，下面将参照图9至图11来描述用以实施本公开的技术的信令交互过程。

图9是示出根据本公开的实施例的信令交互过程的示例的流程图。该示例对应于用户设备位于基站覆盖范围内且基站配置由基站进行资源调度的场景。
如图9所示，在步骤S901中，基站与用户设备建立初始连接(即， RRC_CONNECTED)，之后，基站在步骤S902中将资源集合配置信息和候选参数集配置信息(包括基站基于例如资源集合配置信息、物理信道信息和业务类型信息中的一个或多个而确定的一个或多个参数集)包括在例如RRC信令中发送至用户设备。应指出，在步骤S902中，资源集合配置信息和候选参数集配置信息可以相关联地发送至用户设备，或者也可以彼此独立地进行发送。
接下来，用户设备在步骤S903中获取将要通过直通链路通信进行传输的信息，包括该通信业务的优先级，并且在步骤S904中所获取的优先级信息包括在资源配置请求中发送给基站，以请求基站为其分配资源。在步骤S905中，用户设备周期性地或响应于事件触发将所测量的速度信息、信道繁忙率和/或信道占用率上报给基站。在步骤S906中，基站可以基于来自用户设备的信息中的一个或多个来进行资源分配和参数集选择，然后在步骤S907中将关于所分配的资源和所选择的参数集的信息通过例如sidelink grant下发给用户设备，从而用户设备可以在步骤S908中基于所接收到的资源配置信息和参数集配置信息进行直通链路通信以进行信息发送。
应指出，图9所示的信令交互过程仅是示例，本领域技术人员也可以根据本公开的原理和实际情况而对其进行适当的修改，并且这样的修改显然应认为落入本公开的范围内。例如，取代执行上述步骤S904和步骤S905，用户设备也可以根据所接收到的候选参数集的配置信息，对所获取的这些信息进行整合和预处理，以得到例如参数集选择范围的指示信息，并且将该指示信息发送给基站。在已确定了资源集合配置信息与候选参数集配置信息的对应关系的情况下，基站可以根据该指示信息同时进行资源分配和参数集选择。
[3-2.基站覆盖范围内且由用户设备自主选择资源的场景中的示例]
图10是示出根据本公开的实施例的信令交互过程的另一示例的流程图。
该示例对应于用户设备处于基站的覆盖范围内且基站配置由用户设备自主选择资源的场景。在该示例中，仍由基站进行候选的资源集合和参数集的配置，但是具体的资源和参数集选择将在用户设备侧执行。
图10所示的步骤S1001至步骤S1003中的处理与图9所示的步骤S901至步骤S903中的处理基本上相同，在此不再赘述。在步骤S1004中，用户设备基于所获取的数据业务的优先级而在基站配置的候选资源集合中选择资源， 并且在步骤S1005中，用户设备基于速度信息、信道繁忙率、信道占用率以及数据业务优先级等信息中的一个或多个而从候选参数集中选择要使用的参数集。接下来，在步骤S1006中，用户设备基于所选择的资源和参数集进行直通链路通信以进行信息发送。
同样地，应指出，图10所示的信令交互过程仅是示例，本领域技术人员也可以根据本公开的原理和实际情况而对其进行适当的修改，并且这样的修改显然应认为落入本公开的范围内。例如，在资源配置与参数集配置彼此相关联的情况下，上述步骤S1004和步骤S1005也可以通过一个步骤来实现，以同时实现资源选择和参数集选择。
[3-3.基站覆盖范围外的场景中的示例]
图11是示出根据本公开的实施例的信令交互过程的又一示例的流程图。
该示例对应于用户设备位于基站的覆盖范围外从而需要自主选择资源的场景。因此，在该示例中，实际上不存在基站与用户设备间的信令交互过程。
在图11所示的示例中，用户设备侧所执行的步骤S1102至S1105中的处理与以上参照图10描述的步骤S1003至步骤S1006中的处理基本上相同，区别仅在于，在步骤S1101中，用户设备可以通过例如读取存储器而获取默认的资源集合配置和参数集配置或者上一次从基站接收到的资源集合配置和参数集配置作为候选的资源集合和参数集，从而在步骤S1103和步骤S1104中，不同于步骤S1004和步骤S1005中分别从基站通过RRC信令实时配置的候选资源集合和候选参数集中进行选择，而是从预先配置的候选资源集合和候选参数集中进行资源和参数集选择，并在步骤S1105中基于所选择和资源和参数集进行直通链路通信。
同样地，应指出，图11所示的信令交互过程仅是示例，本领域技术人员也可以根据本公开的原理和实际情况而对其进行适当的修改，并且这样的修改显然应认为落入本公开的范围内。例如，该信令交互过程还可以包括以下步骤：用户设备获取资源集合配置信息、物理信道信息和业务类型信息中的一个或多个，并且基于这些信息而进行资源选择和参数集选择。
此外，还应指出，尽管在图9至图11中为了便于描述而以时间序列对各个步骤进行了编号，但是这些编号并不表示这些步骤执行的先后顺序。实际上， 一些步骤可以是并行执行的，或者顺序是可以相互调换的，等等。
<4.根据本公开的方法实施例>
与上述装置实施例相对应的，本公开提供了以下方法实施例。
图12是示出根据本公开的实施例的无线通信系统中的基站侧的方法的过程示例的流程图。
如图12所示，根据该实施例的方法开始于步骤S1201。在步骤S1201中，基于至少资源集合配置信息、物理信道信息和业务类型信息中的一个或多个，确定用于直通链路通信的一个或多个参数集的配置信息。参数集包括至少子载波间隔和循环前缀类型，并且优选地还包括子帧中的时隙数量、时隙中的OFDM符号数量和帧中的时隙数量中的一个或多个。
接下来，该方法进行到步骤S1202。在步骤S1202中，控制基站将所确定的一个或多个参数集的配置信息发送至用户设备，以使得用户设备基于一个或多个参数集进行直通链路通信。优选地，可以将该配置信息包括在例如RRC信令的高层信令中、并且与资源集合配置信息相关联地发送给用户设备。
优选地，该方法还可以包括如下步骤：基于来自用户设备的与至少用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个有关的信息，从一个或多个参数集中选择用于直通链路通信的参数集；以及将所选择的参数集包括在例如sidelink grant的物理层信令中发送给用户设备。此外，优选地，在直通链路通信是载波聚合通信的情况下，针对载波聚合通信中的每个成员载波而从一个或多个参数集中选择参数集。
应指出，这里参照图12描述的基站侧的方法实施例是与以上描述的基站侧的装置实施例相对应的，因此在此未详细描述的内容可参见以上相应位置的描述，在此不再赘述。
图13是示出根据本公开的实施例的无线通信系统中的用户设备侧的方法的过程示例的流程图。
如图13所示，根据该实施例的方法开始于步骤S1301。在步骤S1301中，获取用于直通链路通信的一个或多个参数集。优选地，可以通过对包括在例如来自基站的高层信令中的配置信息进行解码来获取一个或多个参数集。替选地，这一个或多个参数集也可以是预先配置的。
接下来，该方法进行到步骤S1302。在步骤S1302中，控制用户设备基于一个或多个参数集进行直通链路通信。
优选地，该方法还可以包括以下步骤：将与至少用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个有关的信息以及可选的其他信息发送至基站；通过对例如来自基站的物理层信令进行解码而获取基站基于这些信息选择的参数集；以及基于所选择的参数集进行直通链路通信。
优选地，该方法还可以包括以下步骤中的一个或多个：基于与至少用户设备的移动速度、信道繁忙率、信道占用率和直通链路通信的数据业务优先级中的一个或多个有关的信息，可选地基于涉及直通链路通信的其他设备的相关信息，从一个或多个参数集中选择要用于直通链路通信的参数集，并基于所选择的参数集进行直通链路通信；将所选择的参数集包括在例如SCI信令中以发送给其他设备；以及通过对来自其他设备的SCI信令进行解码来获取参数集，并基于所获取的参数集进行信息接收。
应指出，这里参照图13描述的用户设备侧的方法实施例是与以上描述的用户设备侧的装置实施例相对应的，因此在此未详细描述的内容可参见以上相应位置的描述，在此不再赘述。
还应指出，尽管以上描述了根据本公开的实施例的无线通信系统中的方法的过程示例，但是这仅是示例而非限制，并且本领域技术人员可根据本公开的原理对以上实施例进行修改，例如可对各个实施例中的步骤进行添加、删除或者组合等，并且这样的修改均落入本公开的范围内。
此外，还应指出，尽管在附图中和以上描述中以流程图的顺序描述了根据本公开的实施例的无线通信系统中的方法的过程示例，但是根据本公开的方法的执行顺序并不限于此，而是这些处理也可并行地执行或者根据需要来执行。
<5.根据本公开的技术的应用场景示例>
下面将结合具体的场景示例来描述根据本公开的技术的应用，并给出了适合于各个应用场景示例的参数集的优选配置。应指出，在针对各个应用场景示例的描述中，将仅详细描述在该应用场景中的特定配置，而省略了以上描述的在各种应用场景下的共同配置的详细描述。
[5-1.NR V2V场景中的示例]
图14是示出根据本公开的技术在车辆间通信(V2V)场景中的应用示例的示意图。
如图14所示，车辆用户1同时与多个车辆用户2、3和4进行直通链路通信，并且处于基站的覆盖范围之内，从而车辆用户1可以从基站接收一个或多个候选资源集合和一个或多个候选参数集的配置信息。
车辆用户1具有与多个车辆用户进行直通链路通信的需求，从而可以由基站或车辆用户1根据上述诸如数据业务优先级、信道繁忙率、信道占用率、移动速度等的信息，选择分别适用于车辆用户1与车辆用户2、3和4间的直通链路通信的参数集，在图14中分别被标记为参数集配置1、参数集配置2和参数集配置3。在完成了资源分配和参数集选择之后，车辆用户1可以基于参数集配置1、参数集配置2和参数集配置3分别与车辆用户2、3和4进行V2V通信。应指出，这里的参数集配置1、参数集配置2和参数集配置3可以是相同的参数集或者也可以是不同的参数集，可以根据实际的通信状况来具体设置，本公开对此不做限制。
在该示例中，通过基于业务类型、信道状况、移动速度、接收方特性等等因素而选择适当的参数集，可以保证不同车辆间的V2V通信对时延、可靠性等性能指标的要求。
考虑到V2V业务的特点，即，既有对时延要求较高的安全类业务，又有对吞吐量、频谱利用率要求较高的数据类业务，此外考虑到NR V2V与LTE V2V在未来通信场景中可能长期共存，因此在该场景下可能支持的参数集对应的参数μ的取值可以包括-4、-3、-2、-1、0、1、2、3、4、5、6、7。优选地，参数μ的取值可以包括-3、-2、-1、0、1、2、3、4。进一步优选地，参数μ的取值可以包括--2、-1、0、1、2。若只能选择配置一个固定的参数集作为V2V的唯一使用范围，考虑到NR V2V和LTE V2V的共存问题，应选用μ＝0，即子载波间隔为15kHz的参数集配置。
[5-2.NR V2X自动排队驾驶场景中的示例]
图15是示出V2X的四大类使用场景的示意图。
如图15所示，V2X包括四大类使用场景，分别是自动排队驾驶(platooning)、远程驾驶(remote driving)、增强驾驶(advanced driving)以及支持扩展传感器(extended sensors)，其中，每个使用场景均可应用本公开的技术，以支持可配置的参数集设计。
下面将作为示例进一步详细地描述自动排队驾驶场景中的示例。图16是示出根据本公开的技术在V2X的自动排队驾驶(platooning)场景中的应用示例的示意图。
如图16所示，在自动排队驾驶场景中，作为车队管理者的车头用户需要负责车队驾驶过程的资源申请、分配以及公共信息广播。车队管理者同时分别利用参数集配置4至参数集配置6与车辆用户1、2和3进行V2V通信，这与以上参照图14描述的应用场景示例类似，在此不再详细描述。
这里将以广播通信为例，描述在该场景中由车队管理者负责申请用于车队成员间的广播通信的参数集的示例。具体描述如下：车头用户和车队成员彼此之间共享用户基本信息，包含但不限于下列内容：移动速度、业务类型、信息处理能力(是否支持载波聚合，接收机的处理的能力等)、待传输数据业务的优先级、资源分配情况等。
车头用户作为车队管理者了解其他车队成员的用户基本信息，可以由车头用户选择用于车队成员间的信息广播的参数集。替选地，也可以由车头用户将所了解的其他车队成员的信息转发至基站并由基站来选择参数集。
车头用户通过SCI信令或车队内部通信等方式告知其他车队成员用户所选定的参数集配置。该选定的参数集配置可以通过广播、组播和/或单播的方式被发送至其他车队成员用户。
车队成员通过解码相关信令获取所选取的参数集配置。
车头用户利用所选取的参数集配置进行信息广播，其他车队成员基于解码得到的参数集配置接收车头用户广播的信息。
在该场景示例中，针对广播通信中的不同内容，可以提供不同的参数集，这样可以有效提高资源的使用效率。
另外，应指出，图16中所示出的参数集配置1至参数集配置3表示各个车队成员可以在接收来自车辆管理者的广播内容的同时与其他车辆用户进行V2V通信。参数集配置1至参数集配置3分别表示车辆管理者与队列成员1 至队列成员3进行V2V通信时所使用的参数集配置，它们可以是相同的或者可以是不同的，在此不再详述。
考虑到platooning场景的特点，即，由车头作为车辆管理者进行车队成员管理以及资源申请，车队成员之间频繁进行通信，一方面可能需要共享大数据量的信息如摄像头信息等，另一方面可能还需要及时共享安全信息等，在该场景下可能支持的参数集对应的参数μ的取值可以包括-4、-3、-2、-1、0、1、2、3、4，优选地包括-2、-1、0、1、2。若只能选择配置一个固定的参数集，考虑到NR V2X和LTE V2X的共存问题，应选用μ＝0，即子载波间隔为15kHz的参数集配置。
[5-3.NR直通链路载波聚合通信场景中的示例]
图17是示出根据本公开的技术在载波聚合通信场景中的应用示例的示意图。
如图17所示，假设车辆用户1与车辆用户2在基于上述过程建立了基本的直通链路通信(这里为V2V)之后，基于通信双方的需求或者根据高层信令的指示，车辆用户1与车辆用户2要进行载波聚合通信，需要执行诸如测量、载波选择、聚合等操作，则可以针对每个聚合的成员载波配置适当的参数集。在图17所示的示例中，假设车辆用户1作为发送者，车辆用户2作为接收者，聚合了四个成员载波，分别是成员载波CC0、成员载波CC1、成员载波CC2和成员载波CC3。
针对各个成员载波所承载的业务类型、各个载波的通信条件等等，可以针对每个成员载波分别配置适当的参数集。具体配置过程如下：车辆用户1由高层配置或通过与车辆用户2进行直通链路通信(例如，上述建立的基本V2V通信)，获取载波聚合所需传输的业务内容、载波选择情况、资源分配等基本消息。
●基于各个成员载波所对应的业务类型、通信条件等选择不同成员载波在通信过程中使用的参数集配置。这里的选择可以由基站来执行、由车辆用户1单独选择或者由车辆用户1联合车辆用户2进行选择，本公开对此不做具体限制。
●车辆用户1通过成员载波之一告知车辆用户2针对各个成员载波选定的 参数集配置，或者也可以由基站分别向车辆用户1和车辆用户2发送各个成员载波所对应的参数集配置。
●车辆用户1和车辆用户2基于针对各个成员载波所配置的参数集而进行载波聚合通信。
在图17所示出的示例中，成员载波CC0和成员载波CC1对应于参数集配置1，并且成员载波CC2和成员载波CC3对应于参数集配置2，但是这仅是示例而非限制，成员载波CC0至CC3可以基于实际的通信状况而对应于相同或不同的参数集配置。
在载波聚合通信场景中，根据各个成员载波传输的内容、通信条件等因素而选择对应的参数集配置，可以有效地提高载波聚合的效率。
考虑到载波聚合的特点，即，通信双方可以使用多个成员载波同时或者不同时进行通信。例如，不同成员载波可以传输不同类型的通信业务，在该场景下可能支持的参数集对应的参数μ的取值可以包括-4、-3、-2、-1、0、1、2、3、4，优选地包括-4、-3、-2、-1、0、1、2。特别地，载波聚合通信中进行信令和控制信息传输的成员载波更适用的参数μ的取值可以包括0、1、2，而进行数据业务传输的成员载波更适用的参数μ的取值可以包括-2、-1、0。
[5-4.NR D2D场景中的示例]
图18是示出根据本公开的技术在D2D通信场景中的应用示例的示意图。
如图18所示，设备1、设备2和设备3都在基站的覆盖范围之内，其中，设备2分别与设备1和设备3进行设备到设备(D2D)通信。设备2与设备1之间的通信内容与设备2与设备3之间的通信内容不一定相同，从而可能适用于不同的参数集配置。此外，随着传输内容和要求的改变，设备之间进行设备到设备通信所使用的参数集配置也会发生改变。可能的切换过程如下：
●设备2与设备1使用参数集配置1进行设备到设备通信，在图18中以实线箭头表示。
●设备2与设备1进行设备到设备通信的业务内容和要求、通信条件等发生改变，通信过程不再适用参数集配置1，而适用于参数集配置3。
●设备2和设备1在约定时间期满之后切换至参数集配置3进行设备到设备通信，在图18中以虚线箭头表示。
在D2D场景中，可以根据不同的通信需求切换不同的参数集配置，从而可以有效地应对场景变化带来的影响。
类似地，在机器类通信(MTC)场景以及其它直通链路通信场景中，也可以根据通信需求的变化而灵活地选择配置更优的参数集。
考虑设备到设备通信的特点，在该场景下可能支持的参数集对应的参数μ的取值可以包括-2、-1、0、1、2、3、4、5、6、7，优选地可以包括-2、-1、0、1、2、3。
[5-5.NR无人机通信场景中的示例]
图19是示出根据本公开的技术在无人机通信场景中的应用示例的示意图。
在图19所示的示例中，无人机1作为排头用户，可以承担与车头用户类似的功能。图19所示的无人机通信场景中的应用示例与以上参照图16描述的V2X自动排队驾驶场景中的应用示例基本上相同，在此不再赘述。区别仅在于，考虑到无人机通信的特点，在进行参数集选择时，还需要另外考虑诸如用户设备的当前高度、海拔高度、风速、气压、温度、能见度、湿度等更多的因素。
考虑到无人机通信场景的特点，即，比V2X场景更高的时延要求以及数据量要求，在该场景下可能支持的参数集对应的参数μ的取值可以包括-7、-6、--5、-4、-3、-2、-1、0、1、2、3、4、5、6、7、8。如果优先考虑通信的可靠性，则参数μ的取值可以优选地包括2、3、4、5；如果优先考虑通信的有效性，则参数μ的取值可以优选地包括-6、-5、-4、-3。
[5-6.NR V2I场景中的示例]
图20是示出根据本公开的技术在V2I场景中的应用示例的示意图。
如图20所示，车辆用户1和车辆用户2分别与基站和路边单元(Roadside Unit，RSU)进行车辆到基础设施通信(V2I)，从而分别适用于两种不同的参数集配置，即，参数集配置1和参数集配置2。随着车辆到基础设施通信(V2I)内容和要求的改变，通信过程适用的参数集配置也会改变。具体的参数集选择由基站或者路边单元设施进行下发配置，从而车辆用户可以在通信过程中动态 地调整所用参数集。
考虑到V2I场景的通信特点，通信双方为车辆用户和相对固定的基础设施，在该场景下可能支持的参数集对应的参数μ的取值可以包括-2、-1、0、1、2、3、4、5，优选地可以包括-1、0、1、2。
应指出，尽管以上针对各个应用场景的特点而给出了各个应用场景下的参数集配置的可能选择范围，但是根据实际情况，在各个应用场景下也可能选择不同于上述示例选择范围的参数集，这些不同的参数集选择同样应认为落入本公开的保护范围内。
还应指出，尽管以上参照图14至图20描述了根据本公开的技术的应用场景的示例，但是应理解，这仅是示例而非限制，并且本领域技术人员也可以根据本公开的原理、结合应用场景的特点而对本公开的技术进行适当的修改以适用于除上述示例场景之外的任何直通链路通信场景。
根据上述本公开的实施例以及应用场景示例，不同于现有技术中直通链路通信中的固定参数集配置，针对NR直通链路通信的特点，提出了根据实际应用场景而综合考虑一个或多个因素对参数集进行灵活且合理的配置，以便满足直通链路通信的各个应用场景下的通信性能需求。此外，针对所提出的可配置的参数集，还提供了使得直通链路通信的收发双方能够同步参数集配置的有效解决方案。
应指出，取代以上优点或者与上述优点一起，其他优点和效果在本领域技术人员阅读了本公开的技术内容之后也将是显然的，这里不再一一列举。
还应指出，尽管以上分别针对由基站进行参数集选择和由用户设备进行参数集的情况描述了本公开的实施例，但是这仅是为了便于描述和清楚性而不构成任何限制，在实际应用本公开的技术时，可以对上述实施例进行适当的组合。另外，应指出，无论是由基站还是用户设备选择最终用于直通链路通信的参数集，都需要结合实际的应用场景具体考虑上述各个选择因素，以便兼顾系统稳定性和频谱效率。
此外，根据本公开的实施例，还提供了一种电子设备，该电子设备可包括收发机和一个或多个处理器，这一个或多个处理器可被配置成执行上述根据本公开的实施例的无线通信系统中的方法或装置中的相应单元的功能，并且收发机可以承担相应的通信功能。
应理解，根据本公开的实施例的存储介质和程序产品中的机器可执行的指令还可以被配置成执行与上述装置实施例相对应的方法，因此在此未详细描述的内容可参考先前相应位置的描述，在此不再重复进行描述。
相应地，用于承载上述包括机器可执行的指令的程序产品的存储介质也包括在本发明的公开中。该存储介质包括但不限于软盘、光盘、磁光盘、存储卡、存储棒等等。
<6.用以实施本公开的装置和方法的实施例的计算设备>
另外，还应该指出的是，上述系列处理和装置也可以通过软件和/或固件实现。在通过软件和/或固件实现的情况下，从存储介质或网络向具有专用硬件结构的计算机，例如图21所示的通用个人计算机2100安装构成该软件的程序，该计算机在安装有各种程序时，能够执行各种功能等等。图21是示出作为本公开的实施例中可采用的信息处理设备的个人计算机的示例结构的框图。
在图21中，中央处理单元(CPU)2101根据只读存储器(ROM)2102中存储的程序或从存储部分2108加载到随机存取存储器(RAM)2103的程序执行各种处理。在RAM 2103中，也根据需要存储当CPU 2101执行各种处理等时所需的数据。

根据需要，驱动器2110也连接到输入/输出接口2105。可拆卸介质2111比如磁盘、光盘、磁光盘、半导体存储器等等根据需要被安装在驱动器2110上，使得从中读出的计算机程序根据需要被安装到存储部分2108中。
在通过软件实现上述系列处理的情况下，从网络比如因特网或存储介质比如可拆卸介质2111安装构成软件的程序。
本领域的技术人员应当理解，这种存储介质不局限于图21所示的其中存 储有程序、与设备相分离地分发以向用户提供程序的可拆卸介质2111。可拆卸介质2111的例子包含磁盘(包含软盘(注册商标))、光盘(包含光盘只读存储器(CD-ROM)和数字通用盘(DVD))、磁光盘(包含迷你盘(MD)(注册商标))和半导体存储器。或者，存储介质可以是ROM 2102、存储部分2108中包含的硬盘等等，其中存有程序，并且与包含它们的设备一起被分发给用户。
[7.本公开的技术的应用示例]
本公开的技术能够应用于各种产品。例如，本公开中提到的基站可以被实现为gNodeB(gNB)、任何类型的eNB(诸如宏eNB和小eNB)、传输接收点(TRP)、企业长期演进(eLTE)-eNB等等。小eNB可以为覆盖比宏小区小的小区的eNB，诸如微微eNB、微eNB和家庭(毫微微)eNB。代替地，基站可以被实现为任何其他类型的基站，诸如NodeB和基站收发台(Base Transceiver Station，BTS)。基站可以包括：被配置为控制无线通信的主体(也称为基站设备)；以及设置在与主体不同的地方的一个或多个远程无线头端(Remote Radio Head，RRH)。另外，下面将描述的各种类型的终端均可以通过暂时地或半持久性地执行基站功能而作为基站工作。
例如，本公开中提到的用户设备可以被实现为车辆、移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)、车载终端(诸如汽车导航设备)、无人机、移动台等等。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
以下将参照图22至图25描述根据本公开的应用示例。
<7-1.关于基站的应用示例>
(第一应用示例)
图22是示出可以应用本公开内容的技术的eNB的示意性配置的第一示例的框图。eNB 1400包括一个或多个天线1410以及基站设备1420。基站设备1420和每个天线1410可以经由RF线缆彼此连接。
天线1410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1420发送和接收无线信号。如图22所示，eNB 1400可以包括多个天线1410。例如，多个天线1410可以与eNB 1400使用的多个频段兼容。虽然图22示出其中eNB 1400包括多个天线1410的示例，但是eNB 1400也可以包括单个天线1410。
基站设备1420包括控制器1421、存储器1422、网络接口1423以及无线通信接口1425。
控制器1421可以为例如CPU或DSP，并且操作基站设备1420的较高层的各种功能。例如，控制器1421根据由无线通信接口1425处理的信号中的数据来生成数据分组，并经由网络接口1423来传递所生成的分组。控制器1421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1421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eNB或核心网节点来执行。存储器1422包括RAM和ROM，并且存储由控制器1421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)。
