Abstract

本公开涉及电子装置、无线通信方法和计算机可读介质。根据一个实施例的用于无线通信的电子装置包括处理电路。处理电路被配置为从非授权频段上的预先分配的多个资源块中选择要用于自动上行传输的资源块，以及进行控制以利用所选择的资源块进行自动上行传输。

Description

电子装置、无线通信方法和计算机可读介质 技术领域
本公开一般涉及无线通信领域，更具体地，涉及用于用户设备侧和基站侧的电子装置、无线通信方法以及计算机可读介质。
背景技术
自动上行传输(AUL)是指基站在数据包到达用户之前，预先给用户设备(UE)分配资源用于传输，而不需要当有数据包待传送时再由用户设备向基站申请资源。
在非授权频段工作的UE在信道上进行载波监听(LBT)，同时在信道空闲的时候在信道上执行自动上行传输。自动上行传输包括用于实现解码的控制信息，因此基站会接收这些控制信息，并解码自动上行传输的剩余部分。当无线链路建立之后，基站会为UE的自动上行传输进行配置，同时也会发送动态配置信息来初始化、中断或重配置自动上行传输的参数。
自动上行传输可以减小与申请及调度资源相关的信令开销，当传输量很小时，这一优势尤为显著。另外，自动上行传输可以减短由于等待分配资源而导致的时延，同时增强传输的有效性。
发明内容
在非授权频段，在根据现有方式应用AUL时，需要给用户提前进行资源分配，以保证较小的时延，从而保证对时延要求较高的业务的可靠性。但同时也会出现当前分配某一块资源的用户没有数据包待发送的情况。由于资源的提前分配，此块空闲的资源也无法被其他用户使用来传送数据，从而会一定程度上导致频谱利用率较低的问题。
此外，根据现有方式，资源通常是随机分配的，所以分配的资源不一定适合用户的当前数据传输业务，从而可能无法保证数据传输的可靠性。
针对上述技术问题中的至少一部分提出了本发明。
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，一种用于无线通信的电子装置包括处理电路。处理电路被配置为从非授权频段上的预先分配的多个资源块中选择要用于自动上行传输的资源块，以及进行控制以利用所选择的资源块进行自动上行传输。
根据另一个实施例，一种无线通信方法包括：从非授权频段上的预先分配的多个资源块中选择要用于自动上行传输的资源块；以及利用所选择的资源块进行自动上行传输。
根据又一个实施例，一种用于无线通信的电子装置包括处理电路。处理电路被配置为为多个用户设备共同分配非授权频段上的多个资源块，多个资源块用于自动上行传输。处理电路还被配置为进行控制以接收多个用户设备之一利用从多个资源块中选择的资源块进行的上行传输。
根据再一个实施例，一种无线通信方法包括：为多个用户设备共同分配非授权频段上的多个资源块，多个资源块用于自动上行传输；以及接收多个用户设备之一利用从多个资源块中选择的资源块进行的上行传输。
本发明实施例还包括一种计算机可读介质，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。
本发明实施例有利于提高频谱利用率。

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包括选择单元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选择单元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。
选择单元111被配置为从非授权频段上的预先分配的多个资源块(如：Bandwidth Part)中选择要用于自动上行传输的资源块。
控制单元113被配置为进行控制以利用选择单元111所选择的资源块进行自动上行传输。
根据一个实施例，多个资源块被基站共同分配给多个用户设备。例如，基站可以通过无线资源控制(RRC)信令分配的多个资源块。资源块的划分例如由网络层完成。
如图8所示，UE1和UE2被分配给相同的多个资源块，以减少某一资源块由于被提前分配给唯一一个UE但此UE此时无数据包待传输而造成的资源利用率不高的情况。
在上述实施例的基础上，为对所有空闲资源块加以区分，根据某一资源块是否满足UE将要传输数据包的业务需求，可以为当前所有空闲资源块分配优先级。在传输业务变化的情况下，优先级也可以随之变化。UE可以从中优先选择高优先级的资源块，因此可以为UE选择更匹配其传输模式的资源块。
图2示出了根据另一个实施例的用于无线通信的电子装置的配置示例。
根据本实施例的电子装置200包括处理电路210，处理电路210包括选择单元211、控制单元213和确定单元215。选择单元211和控制单元213与前面说明的选择单元111和控制单元113类似。
确定单元215被配置为确定多个资源块中的每个资源块的优先级。
选择单元211基于确定单元215所确定的优先级选择要用于自动上行传输的资源块。
根据一个实施例，确定单元215被配置为针对多种上行业务中的每种分别确定优先级，并且选择单元211基于确定单元215所确定的优先级选择要用于相应类型的上行业务的资源块。
图9示出了在非连续资源块上的两个承载不同业务的UE的带有优先级的资源块对应方式的示意图。
此外，多种上行业务可以包括在时延方面和/或传输数据量方面具有不同要求的上行业务。例如，多种上行业务可以包括超高可靠超低时延(URLLC)业务和增强移动宽带(eMBB)业务。
相应地，确定单元215可以被配置为，对于URLLC业务，可以对具有较低时延的资源块设置较高的优先级，而对于eMBB业务，可以对较大的资源块设置较高的优先级。
在图9的示例中，假定UE1为URLLC业务，UE2为eMBB业务，其中数字表示UE和资源块对应分配的优先级。由于eMBB传输模式下的数据包通常较大，因此一个eMBB的数据包可能需被分配一个较大的或者多个连续的资源块以满足传输需求。另外，由于URLLC的数据包比eMBB的数据包小，因此分配给URLLC的资源块也会比分配给eMBB的小。
资源块的优先级主要用来反映传输能力。例如，对于URLLC，通常需要更低的传输和重传的时延，对于eMBB，通常需要较大的资源块。
另外，由于信道接入的MCOT与传输和重传有关，因此MCOT越小，时延通常会越低。因此，对于URLLC业务，优先级也可以和上行链路信道接入的MCOT有关。
相应地，根据一个实施例，对于URLLC业务，确定单元215可以被配置为对具有较小最大信道占用时间MCOT的资源块设置较高的优先级。
另外，优先级可以根据UE在每个资源块上进行LBT的反馈来确定。
图3示出了根据另一个实施例的用于无线通信的电子装置的配置示例。
根据本实施例的电子装置300包括处理电路310，处理电路310包括选择单元311、控制单元313、确定单元315和LBT单元317。选择单元311、控制单元313和确定单元315与前面说明的选择单元211、控制单元213和确定单元215类似。
LBT单元317被配置为进行控制以对多个资源块中的每个进行第一载波监听。确定单元315被配置为基于第一载波监听的结果确定多个资源块的优先级。
例如，对于eMBB或者URLLC，资源优先级主要与对应资源上的LBT反馈有关，也就是说，被提前分配的资源处于半激活状态，最快完成LBT的资源块优先级为1(优先级最高)，若多个LBT同时完成则根据数据包大小选择其中一个。
为了满足URLLC对时延的要求，分配给URLLC的资源块的MCOT应当较小，因此当业务确定为URLLC时，即可根据业务类型确定所对应的信道接入优先级，从而确定进行LBT的各项参数，进而根据这些参数进行LBT。对于所有空闲的资源块，完成LBT最快的资源块优先级最高，这也意味着低时延。对于eMBB业务，其优先级可以通过数据包的大小和LBT的反馈来确定。
根据一个实施例，LBT单元317还可以被配置为在利用所选择的资源块进行上行传输之前，针对所选择的资源快进行第二载波监听。
进一步地，选择单元311还可以被配置为在第二载波监听失败或者上行传输失败的情况下，选择优先级比先前所选择的资源块低的另一资源块用于进行上行传输。
此外，LBT单元317还可以被配置为针对不同类型的上行业务，为第二载波监听设置不同的开始定时。
更具体地，LBT单元317可以被配置为将用于URLLC业务的第二载波监听的开始定时设置成早于用于eMBB业务的第二载波监听的开始定时。
例如，当某一空闲资源块同时处于承载URLLC和eMBB两种传输模式的多个UE的资源提前分配状态时，由于URLLC的高优先级，此资源块最终会优先分配给承载URLLC业务的UE使用。为实现这种机制，URLLC业务LBT的开始时间可以早于eMBB业务。当只有承载同一类业务(如只有URLLC业务或只有eMBB业务)的多个UE时，这种资源优先级仍可以使用，此时可根据这些UE尝试接入信道的顺序判断哪个UE可以成功接入信道，优先接入优先级高的信道，而没有成功接入此信道的UE则继续重新尝试接入优先级次之的资源块。
在前面对于根据本发明实施例的电子装置的描述过程中，显然也公开了一些过程和方法。接下来，在不重复已经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4所示，根据一个实施例的无线通信方法包括以下步骤。
在S410，从非授权频段上的预先分配的多个资源块中选择要用于自动上行传输的资源块。
在S420，利用所选择的资源块进行自动上行传输。
本发明实施例可以如前所述地实施在用户设备侧。此外，本发明实施例 也可以实施在基站侧。
如图5所示，根据一个实施例的用于无线通信的电子装置500包括处理电路510。处理电路510包括分配单元511和控制单元513。
分配单元511被配置为为多个用户设备共同分配非授权频段上的多个资源块，多个资源块用于自动上行传输。
控制单元513被配置为进行控制以接收多个用户设备之一利用从多个资源块中选择的资源块进行的上行传输。
此外，控制单元513还可以被配置为进行控制以通过无线资源控制信令向多个用户设备通知多个资源块。
分配单元511还可以被配置为确定所述多个资源块，使得所确定的多个资源块包括分别适用于在时延方面和/或传输数据量方面具有不同要求的上行业务。
对于UE而言，不同的资源块对应着不同的传输结果。当所有空闲资源块的频谱状态不同时，可能会出现随机分配给某一UE的资源块不能很好的满足其传输需求。例如，当此UE待传输的数据包是URLLC业务时，但分配的资源块时延较高，此时此资源块几乎不能被用于传输。另外，由于非授权频段资源块较小且非连续，当同时有承载不同业务的多个UE需提前分配资源时，并不是所有空闲的资源块都可以满足所有的传输需求。
通过提供适用于具有不同要求的上行业务的资源快，使得UE能够选择更适合当前传输的资源块，从而保证传输可靠性。
图6示出了根据另一个实施例的用于无线通信的电子装置的配置示例。
根据本实施例的电子装置600包括处理电路610。处理电路610包括分配单元611、控制单元613和指定单元615。分配单元611和控制单元613的配置与前面说明的分配单元511和控制单元513类似。
指定单元615被配置为为所分配的多个资源块中的每个资源块指定优先级。此外，控制单元613还被配置为进行控制以将所确定的优先级通知给多个用户设备。
图7示出了根据一个实施例的无线通信方法的过程示例。
该方法包括S710，为多个用户设备共同分配非授权频段上的多个资源块，多个资源块用于自动上行传输。
该方法还包括S720，接收多个用户设备之一利用从多个资源块中选择的资源块进行的上行传输。
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根据上述实施例的方法。

无线通信接口2325支持任何蜂窝通信方案(诸如长期演进(LTE)和LTE-先进)，并且经由天线2310来提供到位于gNB 2300的小区中的终端的无线连接。无线通信接口2325通常可以包括例如BB处理器2326和RF电路2327。BB处理器2326可以执行例如编码/解码、调制/解调以及复用/解复用，并且执行层(例如L1、介质访问控制(MAC)、无线链路控制(RLC)和分组数据汇聚协议(PDCP))的各种类型的信号处理。代替控制器2321，BB处理器2326可以具有上述逻辑功能的一部分或全部。BB处理器2326可以为存储通信控制程序的存储器，或者为包括被配置为执行程序的处理器和相关电路的模块。更新程序可以使BB处理器2326的功能改变。该模块可以为插入到基站设备2320的槽中的卡或刀片。可替代地，该模块也可以为安装在卡或刀片上的芯片。同时，RF电路2327可以包括例如混频器、滤波器和放大器，并且经由天线2310来传送和接收无线信号。
如图12所示，无线通信接口2325可以包括多个BB处理器2326。例如，多个BB处理器2326可以与gNB 2300使用的多个频带兼容。如图12所示，无线通信接口2325可以包括多个RF电路2327。例如，多个RF电路2327可以与多个天线元件兼容。虽然图12示出其中无线通信接口2325包括多个BB处理器2326和多个RF电路2327的示例，但是无线通信接口2325也可以包括单个BB处理器2326或单个RF电路2327。
在图12所示的gNB 2300中，基站侧的无线通信设备的收发装置可以由无线通信接口2325实现。基站侧的电子装置或无线通信设备的处理电路和/或各单元的功能的至少一部分也可以由控制器2321实现。例如，控制器2321可以通过执行存储在存储器2322中的程序而执行基站侧的电子装置或无线通信设备的处理电路和/或各单元的功能的至少一部分。
在上面对本发明具体实施例的描述中，针对一种实施方式描述和/或示出 的特征可以用相同或类似的方式在一个或更多个其它实施方式中使用，与其它实施方式中的特征相组合，或替代其它实施方式中的特征。
应该强调，术语“包括/包含”在本文使用时指特征、要素、步骤或组件的存在，但并不排除一个或更多个其它特征、要素、步骤或组件的存在或附加。
在上述实施例和示例中，采用了数字组成的附图标记来表示各个步骤和/或单元。本领域的普通技术人员应理解，这些附图标记只是为了便于叙述和绘图，而并非表示其顺序或任何其他限定。
此外，本发明的方法不限于按照说明书中描述的时间顺序来执行，也可以按照其他的时间顺序地、并行地或独立地执行。因此，本说明书中描述的方法的执行顺序不对本发明的技术范围构成限制。
