技术领域
本公开涉及通信领域，更具体地，本公开涉及蜂窝链路资源和直连链路资源的分配。
背景技术
在无线通信系统中，终端设备(以下有时也称为用户设备，UE)可以通过基站与服务器进行数据交互，从而实现移动联网功能。终端设备与基站之间的通信链路称为蜂窝链路(以下有时也称为uulink)，包括蜂窝上行链路和蜂窝下行链路。此外，在终端设备之间，可以使用直连链路(3GPP标准中称为sidelink或PC5)进行数据交换。
Sidelink与其它直接连接的网络(例如Wi-Fi、蓝牙)相比，具有一定的优势。例如，相比于Wi-Fi这样的不保证通信质量的网络，sidelink直连链路能够保证稳定的通信质量。另外，与蓝牙相比，sidelink能够提供更高速、更远距离的通信。因此，在需要确保通信质量和通信速度的直连通信的场景下，sidelink是一种较优的选择。
发明内容
在下文中给出了关于本公开的简要概述，以便提供关于本公开的一些方面的基本理解。但是，应当理解，这个概述并不是关于本公开的穷举性概述。它并不是意图用来确定本公开的关键性部分或重要部分，也不是意图用来限定本公开的范围。其目的仅仅是以简化的形式给出关于本公开的某些概念，以此作为稍后给出的更详细描述的前序。
目前，sidelink使用的是上行链路资源。也就是说，sidelink只能在基站服务的小区范围内的上行链路资源中进行通信。另外，uulink的上行链路使用的也是上行链路资源。因此，如果基站为小区内的UE分配了大量的上行链路资源来进行uulink上行通信，就不能保证UE和UE之间有足够的资源实现sidelink通信。此外，对于一个基站而言，上 行链路资源与下行链路资源的总量是有限的，如果基站为小区内的UE分配了大量的下行链路资源来进行uulink下行通信，则上行链路资源可能不足，从而不能保证UE和UE之间有足够的资源实现sidelink通信。
鉴于上述问题中的一个或多个，本公开提供了一种sidelink资源与uulink资源的协调机制，能够根据UE对于sidelink资源和uulink资源的使用需求，对UE合理分配sidelink资源和uulink资源。

图1示出了无线通信中的uulink和sidelink通信的示意图。
假设UE 102与UE 104通过云游戏平台进行互动游戏的场景。游戏数据存放在云游戏服务器(未图示)上，UE 102和UE 104分别通过蜂窝链路(uuilnk)与基站100进行通信，从而经由基站100与云游戏服务器进行数据交互。例如，UE 102和UE 104分别通过uulink上行链路，经由基站100向云游戏服务器发送游戏操控数据。然后，云游戏服务器将UE 102和UE 104操控后更新的游戏内容通过uulink下行链路分别发送至UE 102和UE 104。此外，在UE 102和UE 104之间，通过直连链路(sidelink)来交互游戏互动信息(例如用户移动信息)。
图1例示了UE 102和UE 104由相同的基站100控制的情况。应当理解，UE 102和UE 104也可以分别由不同的基站控制，经由蜂窝链路分别与不同的基站进行通信。
目前，sidelink使用的是上行链路资源。也就是说，UE 102和UE 104之间的sidelink只能在基站100服务的小区范围内的上行链路资源中进行通信。另外，UE 102/104与基站100之间的uulink的上行链路使用的也是上行链路资源。因此，如果基站为小区内的UE分配了大量的上行链路资源来进行uulink上行通信(例如，参与游戏的UE 102/104需要向游戏服务器上传大量的游戏数据，或者小区内的其它UE的上行通信需求大)，就不能保证UE和UE之间有足够的资源实现sidelink通信。此外，对于基站100而言，上行链路资源与下行链路资源的总量是有限的，如果基站100为UE 102/104分配了大量的下行链路资源来进行uulink下行通信(例如，参与游戏的UE 102/104需要从云游戏服务器下载大量的游戏更新数据)，则上行链路资源可能不足，也不能保证UE和UE之间有足够的资源实现sidelink通信。
因此，需要sidelink资源与uulink资源的协调机制，综合考虑UE对于sidelink资源和uulink资源的使用需求，对UE合理分配sidelink资源和uulink资源。
下面参照图2～图6来说明根据本公开的sidelink资源和uulink资源协调分配方案。
图2示出根据本公开的实施例的用于终端设备侧的电子设备2000的示例性配置框图。电子设备2000例如可以用于图1所示的UE 102或UE 104。
在一些实施例中，电子设备2000可以包括处理电路2010。电子设备2000的处理电路2010提供电子设备2000的各种功能。在一些实施例中，电子设备2000的处理电路2010可以被配置为执行用于终端设备侧的电子设备2000的通信方法。
处理电路2010可以指在计算系统中执行功能的数字电路系统、模拟电路系统或混合信号(模拟和数字的组合)电路系统的各种实现。处理电路可以包括例如诸如集成电路(IC)、专用集成电路(ASIC)这样的电路、单独处理器核心的部分或电路、整个处理器 核心、单独的处理器、诸如现场可编程门阵列(FPGA)的可编程硬件设备、和/或包括多个处理器的系统。
在一些实施例中，处理电路2010可以包括需求提供单元2020，被配置为执行后述图3中所示的用于终端设备侧的电子设备2000的通信方法3000中的步骤S3010。
在一些实施例中，电子设备2000还可以包括存储器(未图示)。电子设备2000的存储器可以存储由处理电路2010产生的信息以及用于电子设备2010操作的程序和数据。存储器可以是易失性存储器和/或非易失性存储器。例如，存储器可以包括但不限于随机存取存储器(RAM)、动态随机存取存储器(DRAM)、静态随机存取存储器(SRAM)、只读存储器(ROM)以及闪存存储器。
另外，电子设备2000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。在一些实施例中，电子设备2000可以作为整机而实现为终端设备，并且还可以包括一根或多根天线。
图3示出根据本公开的实施例的用于终端设备侧的通信方法3000的示例性流程图。该通信方法例如可以用于如图2所示的电子设备2000。
如图3所示，在步骤S3010中，终端设备的需求提供单元2020经由蜂窝链路，向基站提供所述终端设备的直连链路资源使用需求以及蜂窝链路资源使用需求，以使所述基站根据所述终端设备的直连链路资源使用需求和所述蜂窝链路资源使用需求，为所述终端设备分配直连链路资源以及蜂窝链路资源。
根据本公开，在综合考虑了UE的直连链路资源使用需求以及蜂窝链路资源使用需求的基础上，对UE分配直连链路资源以及蜂窝链路资源，能够对UE进行更合理的资源分配。
在一些实施例中，UE的直连链路资源使用需求可以由与所述直连链路有关的信道繁忙率(Channel Busy Ratio，CBR)和缓冲状态报告(Busy Status Report，BSR)中的至少一个来指示。CBR可以指示当前信道繁忙的状态，BSR可以指示当前UE需要上传的缓冲数据量。这两个指标都可以用来指示UE的直连链路资源使用需求。例如，UE 102可以将自己的与sidelink有关的CBR和/或BSR上报给基站100，以供基站100进行资源分配。
在一些实施例中，UE的蜂窝链路资源使用需求由与蜂窝链路有关的缓冲状态报告BSR来指示。例如，UE 102可以将自己的与uulink有关的BSR上报给基站100，以供基站100进行资源分配。
应当理解，指示UE的直连链路资源使用需求和蜂窝链路资源使用需求的信息不限 于上文所描述的BSR、CBR，还可以使用其它任何能够表示直连链路资源使用需求、蜂窝链路资源使用需求的信息。例如，UE可以将传输失败的信息或者在需要传输时没有可用资源的情况上报给基站，用于指示相应的资源使用需求。
图4示出根据本公开的实施例的用于基站侧的电子设备4000的示例性配置框图。电子设备4000例如可以用于图1所示的基站100。
在一些实施例中，电子设备4000可以包括处理电路4010。电子设备4000的处理电路4010提供电子设备4000的各种功能。在一些实施例中，电子设备4000的处理电路4010可以被配置为执行用于基站侧的电子设备4000的通信方法。
处理电路4010可以指在计算系统中执行功能的数字电路系统、模拟电路系统或混合信号(模拟和数字的组合)电路系统的各种实现。处理电路可以包括例如诸如集成电路(IC)、专用集成电路(ASIC)这样的电路、单独处理器核心的部分或电路、整个处理器核心、单独的处理器、诸如现场可编程门阵列(FPGA)的可编程硬件设备、和/或包括多个处理器的系统。
在一些实施例中，处理电路4010可以包括需求获取单元4020以及资源管理单元4030，分别被配置为执行后述图5中所示的用于基站侧的电子设备4000的通信方法5000中的步骤S5010和S5020。
在一些实施例中，电子设备4000还可以包括存储器(未图示)。电子设备4000的存储器可以存储由处理电路4010产生的信息以及用于电子设备4010操作的程序和数据。存储器可以是易失性存储器和/或非易失性存储器。例如，存储器可以包括但不限于随机存取存储器(RAM)、动态随机存取存储器(DRAM)、静态随机存取存储器(SRAM)、只读存储器(ROM)以及闪存存储器。
另外，电子设备4000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。在一些实施例中，电子设备4000可以作为整机而实现为终端设备，并且还可以包括一根或多根天线。
应当理解，上述各个单元仅是根据其所实现的具体功能所划分的逻辑模块，而不是用于限制具体的实现方式。在实际实现时，上述各个单元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。
图5示出根据本公开的实施例的用于基站侧的通信方法5000的示例性流程图。该通信方法例如可以用于如图4所示的电子设备4000。
如图5所示，在步骤S5010中，基站的需求获取单元4020经由蜂窝链路，获取终端设备的直连链路资源使用需求以及蜂窝链路资源使用需求。在步骤S5020中，基站的资源 管理单元4030根据所述直连链路资源使用需求以及蜂窝链路资源使用需求，为所述终端设备分配直连链路资源以及蜂窝链路资源。
在一些实施例中，资源管理单元4030可以通过3GPP协议栈MAC的调度器(scheduler)来实现。在另一些实施例中，资源管理单元4030可以在RRC层实现，在RRC层负责RRC管理SPS周期，通过RRC来管理上下行资源的配置。在又一些实施例中，资源管理单元4030还可以是存在于应用媒体控制单元的装置，根据实际的应用数据请求，通过RRC或者MAC的调度器对上下行资源进行合理配置。
根据本公开，在综合考虑了UE的直连链路资源使用需求以及蜂窝链路资源使用需求的基础上，对UE分配直连链路资源以及蜂窝链路资源，能够对UE进行更合理的资源分配。
在一些实施例中，基站的资源管理单元4030可以根据UE的直连链路资源使用需求以及蜂窝链路资源使用需求，调整上行链路资源中直连链路资源所占的比例，根据调整后的所述比例，为UE分配直连链路资源以及蜂窝链路资源。
例如，在图1所示UE 102与UE 104通过云游戏平台进行互动游戏的场景中，当UE 102与UE 104之间的交互较多时，需要较多的sidelink资源。此时，如果UE 102经由基站100向游戏服务器发送的游戏操控数据较少，则使用uulink上行链路资源较少。在这种情况下，根据UE 102向基站100提供的sidelink资源使用需求(例如由sidelink的BSR/CBR指示)和uulink资源使用需求(例如由uulink的BSR指示)可知，UE 102需要较多的sidelink资源，而需要较少的uulink上行资源。因此，基站100的资源管理单元4030可以将上行链路资源中sidelink资源所占的比例增大，从而为UE 102分配更多的sidelink资源。相应地，上行链路资源中uulink上行资源减少，从而为UE 102分配更少的uulink资源。由此，能够根据UE的需求，为UE合理分配sidelink和uulink资源。
在一些实施例中，基站的资源管理单元4030可以根据UE的直连链路资源使用需求以及蜂窝链路资源使用需求，调整上行链路资源与下行链路资源的配比，根据调整后的所述配比，为UE分配直连链路资源以及蜂窝链路资源。
仍然以图1所示的UE 102与UE 104通过云游戏平台进行互动游戏的场景为例，当UE 102与UE 104之间的交互较多时，需要较多的sidelink资源。此时，如果UE 102经由基站100向游戏服务器发送的游戏操控数据也较多，则还需要较多的uulink上行资源。在这种情况下，根据UE 102向基站100提供的sidelink资源使用需求(例如由sidelink的BSR/CBR指示)和uulink资源使用需求(例如由uulink的BSR指示)可知，UE 102需要较多的sidelink资源，并且也需要较多的uulink上行资源。因此，基站100的资源管理单元4030可以将上行链路资源与下行链路资源的配比增大，从而增加上 行链路资源的总量，使得能够为UE 102分配更多的sidelink资源和uulink资源。由此，能够根据UE的需求，为UE合理分配sidelink和uulink资源。
在以上的实施例中，描述了每个UE(例如UE 102和UE 104)向基站(例如基站100)分别提供sidelink和uulink资源使用需求的情况。在该情况下，基站为每一个UE分别分配sidelink资源的情况。
在一些实施例中，经由直连链路相互通信的多个UE可以构成直连通信设备组，直连通信设备组中的主导UE可以获取其它UE的sidelink和uulink资源使用需求，并向基站统一上报。基站根据直连通信设备组的sidelink和uulink资源使用需求，为直连通信设备组分配sidelink资源池。直连通信设备组中的各UE在资源池内自主地选择资源进行sidelink通信。
以下，将参照图6具体描述直连通信设备组与基站之间的通信和资源分配方案。
图6示出了根据本公开的实施例的直连通信设备组与基站之间进行交互的示例性信令图。UE-1至UE-5经由直连链路相互通信，构成直连通信设备组，其中UE-1为主导UE，经由蜂窝链路与基站进行通信。
作为主导UE的UE-1可以经由直连链路，获取其它UE的直连链路资源使用需求以及蜂窝链路资源使用需求。该步骤例如可以通过图6所示的步骤S6000和S6010实现。
具体而言，在步骤S6000中，UE-1向其它UE(即UE-2至UE-5)分别发送测量请求，用于测量其它各UE的uulink和sidelink的资源使用需求。如上文所述，uulink的资源使用需求例如可以由与uulink有关的BSR来指示，sidelink的资源使用需求例如可以由与sidelink有关的BSR和/或CBR来指示。
接下来，在步骤S6010中，UE-1从UE-2至UE-5分别接收测量响应，以获得UE-2至UE-5的uulink和sidelink的资源使用需求。
在步骤S6020中，UE-1根据其自身的资源使用需求以及从其它各UE获得的资源使用需求，确定直连通信设备组的资源使用信息。该资源使用信息例如可以包括直连通信设备组的uulink和sidelink资源使用需求。
在一些实施例中，UE-1可以将直连通信设备组中的各UE中的最大的sidelink资源使用需求确定为该直连通信设备组的sidelink资源使用需求。例如，在使用BSR来指示sidelink资源使用需求的情况下，UE-1可以从各UE(即UE-1至UE-5)各自的sidelink BSR中选择最大的BSR，用以指示最大的sidelink资源使用需求，并作为直连通信设备组的sidelink资源使用需求来上报给基站。另外，对于使用CBR来指示sidelink资源使用需求的情况下，也可以进行类似的处理。
在另一些实施例中，UE-1也可以将直连通信设备组中的各UE中的平均sidelink资源使用需求确定为该直连通信设备组的sidelink资源使用需求。例如，在使用BSR来指示sidelink资源使用需求的情况下，UE-1可以对各UE(即UE-1至UE-5)的sidelink BSR求平均，用平均sidelink BSR来指示直连通信设备组的sidelink资源使用需求，并上报给基站。另外，对于使用CBR来指示sidelink资源使用需求的情况下，也可以进行类似的处理。
在一些实施例中，UE-1可以将直连通信设备组中的各UE(即UE-1至UE-5)的uulink资源使用需求之和确定为直连通信设备组的uulink资源使用需求。例如，在使用BSR来指示uulink资源使用需求的情况下，UE-1可以对各UE(即UE-1至UE-5)的uulink BSR所指示的缓冲数据量进行求和，作为直连通信设备组的uulink BSR上报给基站。
在一些实施例中，UE-1可以收集其它能够表示uulink和sidelink资源利用情况的信息，用于确定直连通信设备组的uulink和sidelink资源使用需求。例如，UE-1可以收集各UE传输失败的信息或者UE在需要传输时没有可用资源的情况，对从各UE收集的这些信息进行分析，以确定直连通信设备组的uulink和sidelink资源使用需求。另外，也可以将这些信息与各UE的sidelink BSR/CBR、uulink BSR一起考虑，从而确定直连通信设备组的uulink和sidelink资源使用需求。
接下来，在步骤S6030中，UE-1经由蜂窝链路向基站发送资源使用信息，从而将直连通信设备组的uulink和sidelink资源使用需求提供给基站。
此外，步骤S6020和步骤S6030描述的是在作为主导UE的UE-1处确定直连通信设备组的资源使用需求并向基站上报的情况。然而，在一些实施例中，该确定过程也可以在基站侧实现。例如，UE-1收集各UE的uulink和sidelink资源使用需求并直接上报给基站，由基站根据这些资源使用需求来确定直连通信设备组的uulink和sidelink资源使用需求。
接下来，在步骤S6040中，基站根据所接收到的资源使用信息来进行资源协调。
在一些实施例中，基站可以根据直连通信设备组的uulink和sidelink资源使用需求，为直连通信设备组分配直连链路资源池。具体而言，基站可以根据上述资源使用需求，判定是上行资源时隙分配过少或者是sidelink资源池的可用资源不足，从而根据具体情况的不同来进行合理的资源分配。
在直连通信设备组的sidelink资源使用需求较大时，sidelink资源池的可用资源可能不足。在该情况下，基站可以动态调整直连链路资源池的大小，从而为直连通信设备组分配更大的直连链路资源池。此时，相应地，用于uulink上行链路的资源会减少。
在直连通信设备组的sidelink资源使用需求和uulink上行资源使用需求都较大时，由于sidelink资源和uulink上行资源使用的都是上行链路资源，因此当前的上行链路资源可能无法满足直连设备组的sidelink和uulink资源使用需求。在该情况下，基站可以调整上行链路资源与下行链路资源的配比，使得上行链路资源的比例增大。在调整配比后，可用的上行链路资源变多，从而能够满足sidelink资源和uulink上行资源的使用需求。
在一些实施例中，基站可以根据直连通信设备组的直连链路资源使用需求以及蜂窝链路资源使用需求，为直连通信设备组分配蜂窝下行链路组播资源。
例如，在UE-1至UE-5进行游戏交互的场景下，UE-2通过uulink上行链路将游戏互动数据上传给云游戏服务器，该游戏互动数据的上传会导致游戏内容的更新，游戏内容的更新需要通过uulink下行链路发送给所有UE-1至UE-5，以确保各UE都及时获得游戏数据的更新。也就是说，即便只有一个UE的上行链路的数据上传，也可能导致直连通信设备组中的所有UE产生下行链路资源使用需求。针对这种情况，在一些实施例中，基站可以根据直连通信设备组的uulink和sidelink资源使用需求，为直连通信设备组统一分配uulink下行组播资源。直连通信设备组中的各UE例如使用该组播资源来下载游戏数据，从而能够保证各UE都及时获得数据更新。
在一些实施例中，也可以由云游戏服务器根据直连通信设备组上传的游戏互动数据，估计该直连通信设备组的uulink下行组播资源需求，并向基站通知。基站根据该uulink下行组播资源需求为直连通信设备组分配uulink下行组播资源。
接下来，在步骤S6050中，基站向作为主导UE的UE-1发送资源更新。例如，基站可以将为直连通信设备分配的sidelink资源池和/或uulink下行组播资源发送给UE-1。
在步骤S6060中，UE-1向其它UE分别发送该资源更新。例如，UE-1可以向其它UE分别发送sidelink资源池和/或uulink下行组播资源。由此，各UE可以在更新的sidelink资源池和/或uulink下行组播资源中进行相应的sidelink通信和uulink通信。
此外，在步骤S6050中，基站也可以直接将资源更新分别发送给各UE。在该情况下，无需在步骤S6060中由作为主导UE的UE-1向其它UE发送资源更新。
以上结合图6描述了直连通信设备组与基站之间的通信和资源分配方案。在该方案中，仅由主导UE经由uulink与基站进行通信，而无需每个UE分别与基站通信。由此，只需要主导UE保持与基站的链接状态即可，其它UE可以处于未链接状态，从而能够降低基站进行资源分配的复杂度并降低系统开销。通过这样的方式，尤其是在直连通信设备组中的UE数量较大的情况下，能够更显著地降低资源分配的复杂度和系统开销。
在一些实施例中，直连通信设备组中的主导UE除了获取各UE的uulink和sidelink 资源使用需求之外，还可以获取各UE的位置信息。该步骤例如也可以通过图6所示的步骤S6000和S6010来实现，其中步骤S6000中的测量请求包括对其它UE的位置信息的测量请求，步骤S6010中的测量相应包括由其它UE测量出的各自的位置信息。
接下来，在步骤S6020中，UE-1根据各UE的位置信息，确定直连通信设备组中的终端设备之间的最大距离。该最大距离可以包括在直连通信设备组的资源使用信息内，在步骤S6030中发送给基站。
在步骤S6040中，基站根据接收到的最大距离来进行资源协调，确定为该直连通信设备组分配的直连链路资源池的空间上的使用范围和所述直连通信设备组的最小直连通信发射功率中的至少一个。
在一些实施例中，为了确保直连通信设备组中的各UE都能够使用相同的sidelink资源池，可以利用各UE之间的最大距离来确定直连链路资源池的空间上的使用范围。由此，使得各UE都位于该使用范围内，因此能够确保各UE都能够使用相同的sidelink资源池。
在一些实施例中，也可以利用各UE之间的最大距离来确定直连通信设备组的最小直连通信发射功率。例如，可以将能够保证该最大距离的传输的发射功率确定为最小直连通信发射功率。由此，能够在保证传输的质量的情况下节约直连通信组中的各UE的发射功率。
接下来，与上文的描述类似地，在步骤S6050中，基站向UE-1发送资源更新(例如直连链路资源池的空间上的使用范围和/或直连通信设备组的最小直连通信发射功率)，在步骤S6060中，UE-1将该资源更新发送给其它UE。
在一些情况下，即使调整了上行链路中sidelink资源所占的比例，并且调整了上行链路资源与下行链路资源的配比，也无法实现uulink与sidelink的资源协调。例如，如果小区内存在大量需要uulink下行链路资源的UE，或者游戏中的UE需要进行大量的数据下载，则上行链路资源可能不足，进而导致没有足够的sidelink资源。在该情况下，可以通过在UE侧或基站侧设置应用媒体控制单元，来调整UE的应用层媒体分发方式。
在一些实施例中，应用媒体控制单元可以设置在UE侧，根据UE的sidelink和uulink资源使用需求，调整UE的应用层媒体分发方式。例如，在小区内需要大量的uulink下行链路资源而无法确保足够的sidelink资源的情况下，可以调整UE的应用层媒体分发方式，使得UE之间的交互更多的地通过uulink来实现，在网络侧实现更多的渲染，从而减少sidelink资源使用需求。相反，在小区内的uulink下行链路资源需求较少而能够保证较多的sidelink资源的情况下，可以调整UE的应用层媒体分发方式，使得UE之间的交互更多地通过sidelink来实现，并且在UE侧实现更多的本地渲染。
在一些实施例中，应用媒体控制单元也可以设置在基站侧，根据UE向基站提供的sidelink和uulink资源使用需求，向UE提供用于调整UE的应用层媒体分发方式的媒体分发控制指令。
另外，在多个UE进行游戏互动并与游戏服务器交互游戏数据的场景下，应用媒体控制单元也可以相应地对游戏服务器的媒体分发方式进行调整，以适应uulink和sidelink资源使用需求。
根据上述实施例，可以通过应用层来根据网络性能调整应用的内容分发，从而提升用户体验。
接下来，考虑相邻小区之间的干扰的情况。
相邻小区的上行链路和下行链路如果没有进行协调则可能会导致相邻小区间的干扰。因此，在一些实施例中，基站根据与相邻基站之间的干扰情况，调节针对UE的直连链路资源以及蜂窝链路资源的分配。由此，能够减小相邻小区间的干扰的情况。
在一些实施例中，基站可以与相邻基站进行UE位置信息的交互。该UE位置信息例如可以指示由该基站服务的单个UE的地理位置或者多个UE构成的直连通信设备组的地理位置。基站可以通过与相邻基站的UE位置信息的交互，确定该UE位置信息所指示的位置处与相邻基站发生干扰的情况，并据此调整针对UE的直连链路资源以及蜂窝链路资源的分配(例如上行链路资源中sidelink所占的比例、上行链路资源与下行链路资源的配比)，以减少相邻小区之间的干扰。
在一些实施例中，如果基站与相邻基站都是NR基站，则基站可以通过Xn接口来与相邻基站进行信息交互与协调。在一些实施例中，如果基站与相邻基站都是LTE基站，则基站可以通过X2接口来与相邻基站进行信息交互与协调。应当理解，在基站为NR基站并且相邻基站为LTE基站(反之亦然)的情况下，该基站也可以与相邻基站进行信息交互与协调。在一些实施例中，基站也可以通过波束赋形方向(针对毫米波波段)控制，在空间上减小相邻小区的资源干扰问题。
根据该实施例，能够通过与相邻小区之间信息交互与协调，调节针对UE的直连链路资源以及蜂窝链路资源的分配，从而减少相邻小区之间的干扰。
在上文的描述中，以多个UE之间的游戏互动的场景为例，介绍了根据本公开的实施例的sidelink资源和uulink资源的协调分配方案。应当理解，根据本公开的技术也能够类似地应用于同时使用sidelink资源和uulink资源的其它场景，例如车联网、物联网等场景。
