Description

用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2019年8月16日提交中国专利局、申请号为201910759087.3、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”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
本申请涉及无线通信技术领域，具体地涉及非授权频段(unlicensed band)的无线通信中的上行传输技术。更具体地，涉及一种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
在基于新无线(New Radio，NR)技术的各种应用场景中，超高可靠和超低时延通信(Ultra reliable and low latency communication，URLLC)是重要的一个。为了满足URLLC的要求，可以缩短TTI以及mini-slot等有关帧结构的变化，通过缩短调度和反馈的最小单位来满足超低时延的基本需求。此外，还提出了引入上行免调度(Configured Grant，CG)方案以最大程度减小信令开销，从而进一步降低时延。其中，上行免调度指的是用户设备(User Equipment，UE)在与基站取得上行同步后无需基站发送的上行授权及调度信息，可以直接发送上行数据。
另外，针对非授权频段使用的研究越来越受到重视。但是，对于非授权频段而言，由于在使用前需要进行信道是否空闲的检测，其机制本身存在时延，因此，在将上行免调度方案应用于非授权频段时，可能需要另外的设计。

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>
图1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1所示，电子设备100包括：获取单元101，被配置为获取来自基站的控制信息；以及确定单元102，被配置为基于该控制信息确定用户设备能够接入的非授权频段的上行免调度时域资源的多个起始位置。
其中，获取单元101和确定单元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。并且，应该理解，图1中所示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。
电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。这同样适用于随后关于用户设备侧的电子设备的其他配置示例的描述。
如前所述，当用户设备(UE)在非授权频段上进行通信时，在传输数据之前需要首先进行信道是否被占用的能量检测比如先听后说(Listen  Before Talk，LBT)。UE只有在检测到信道处于空闲状态的情况下，才能够接入信道执行数据传输。在采用上行免调度的情况下，UE不需要从基站获取资源调度信息，而是对信道执行LBT且在LBT指示信道空闲(也可称为LBT成功)的情况下直接接入上行免调度资源，以进行物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的传输，如图2a所示。
图2a示出了基于mini-slot(小时隙)的PUSCH调度的情形，对于基于slot的调度可以类似地适用。如图2a所示，UE执行LBT的尝试，在第一个slot中由于LBT成功时能够接入上行免调度时域资源的时间点已经过去，因此UE并不能成功发送PUSCH，而是在第二个slot中再次执行LBT。在第二个slot中，LBT在到达能够接入上行免调度时域资源的时间点前成功，并将信道保留至该时间点，从而成功发送PUSCH。
在本实施例中，图2a中的能够接入上行免调度时域资源的时间点被称为UE能够接入的非授权频段的上行免调度时域资源的起始位置。图2a示出了一个时隙中存在一个起始位置的情况，为了提高接入成功的机会，在一个时隙中可以有多个起始位置。在这种情况下，基站可以通过控制信息将多个起始位置的信息通知给UE。控制信息例如可以包括在无线资源控制(Radio Resource Control，RRC)信令和下行控制信息(Downlink Control Information，DCI)中的至少一个中。
例如，确定单元102基于控制信息确定一个时隙中作为多个起始位置的符号的位置。示例性地，在一个时隙中有14个符号，控制信息可以指示其中的一部分或全部符号作为起始位置，在这些起始位置处，如果UE在此之前已经成功完成了LBT，则可以接入上行免调度时域资源来执行PUSCH的传输。
在一个示例中，控制信息可以包括比特图，确定单元102基于比特图中的每一位确定一个时隙中的每一个符号是否作为起始位置。在一个时隙中有14个符号的情况下，例如，可以采用14位的比特图来分别指示14个符号中的每一个是否作为起始位置。其中，可以将比特图中的位设置为1来表示对应的符号作为起始位置，或者进行相反的设置。比特图中的位的含义可以在基站和UE之间事先约定，也可以由基站进行限定并通过信令比如RRC信令来通知UE。
或者，控制信息可以包括标记位，确定单元102基于该标记位来确定一个时隙中作为多个起始位置的特定符号的集合。在这种情况下，设置特定符号的集合(比如，符号1至10)作为多个起始位置，当标记位取预定值(比如1)时，将该集合中的多个符号作为多个起始位置。采用这种方式，可以减小信令开销。此外，当控制信息包括多个标记位时，还可以基于多个标记位的不同取值来确定作为多个起始位置的不同的特定符号的集合。例如，在两个标记位的情况下，取值“00”对应于符号集合{0,3,5,7}而取值“01”对应于符号集合{1,4,8,10}，等等。
在采用基于slot的PUSCH调度的情况下，确定单元102还被配置为针对每一个起始位置，将上行免调度时域资源的大小确定为从该起始位置起至一个时隙结束的长度，如图3所示。在图3的示例中，例如确定符号1至10均可作为起始位置，在大约第7个符号处LBT成功完成，从而在作为起始位置之一的第8个符号处接入上行免调度时域资源来传输PUSCH，且PUSCH的传输持续到该slot结束。换言之，上行免调度时域资源的大小为从接入时的起始位置起至时隙结束的长度。可以看出，接入时的起始位置越靠前，上行免调度时域资源的大小越大。通过在一个时隙中设置多个起始位置，可以大大提高UE接入上行免调度时域资源的机会，从而降低上行传输时延。
在基于mini-slot的PUSCH调度的情况下，确定单元102例如还可以基于已有的SLIV字段来确定上行免调度时域资源的大小，但是并不采用基于SLIV字段确定的起始符号(即，起始位置)，而是采用上述根据控制信息确定的多个起始位置。该已有的SLIV字段也可以作为控制信息的一部分。或者，确定单元102还可以基于其他的控制信息来确定上行免调度时域资源的大小。即，控制信息还包括另外的指示上行免调度时域资源的大小的信息。
其中，SLIV字段包括在RRC信令的PUSCH-TimeDomainResourceAllocation中，如下所示：
Figure PCTCN2020107689-appb-000001
Figure PCTCN2020107689-appb-000002
在图2a的示例中，如果在一个slot中有多个起始位置时，在第一个slot中，由于LBT的延迟而错过了第一个起始位置，UE仍可在第二个起始位置处接入上行免调度时域资源以传输PUSCH，如图中的虚线框所示。此外，图2b也示出了类似的情形，其中，第二个slot被预留用于PRACH/SSB，UE在第一个slot的第二个起始位置处接入了上行免调度时域资源，避免了产生较大的时延。
在另一个示例中，控制信息可以包括RRC信令中的SLIV字段，确定单元102基于该SLIV字段来确定一个时隙中作为多个起始位置的符号的位置。
在该示例中，SLIV字段的取值被设置为SLIV字段的所有取值中先前未占用取值中的一个或多个。其中，SLIV字段的先前未占用取值的范围为105至127。可以进行设计以使得SLIV的不同取值对应于不同的作为多个起始位置的符号集合。该对应关系例如可以以各种形式预先保存在基站和UE中，以使得当UE获取了SLIV字段的值时可以确定作为多个起始位置的符号的集合。
示例性地，可以使用SLIV＝105来表示符号{0,3,4,5,7}作为多个起始位置的情形，使用SLIV＝127来表示所有符号均可作为多个起始位置的情形，等等。应该理解，这里给出的例子仅是为了理解的需要，并不是限制性的。图4示出了SLIV字段的设置的一个示例的图。如图4所示，除了SLIV已有的取值之外，SLIV还可以取值为127，其代表所有符号(符号0-13)均可以作为用于接入的起始位置，用于PUSCH传输的上行免调度时域资源的大小相应地可以为1至14个符号之一。其中，确定单元102可以被配置为针对每一个起始位置，将上行免调度时域资源的大小确定为从该起始位置起至一个时隙结束的长度。
此外，对于基于mini-slot的PUSCH调度的情形，也可以将上行免调度时域资源的大小设置为其他大小，例如通过SLIV字段来指示，通过控制信息的另外的部分来指示或者具有默认大小。为了便于理解，图5示出了控制信息指示符号{0,3,4,5,7}作为起始位置且上行免调度时域资源的大小为4的具体示例。在图5所示的第一个slot中，例如在大约第6个符号处LBT成功，从而在作为一个起始位置的符号7处接入上行 免调度时域资源，进行长度为4个符号的PUSCH传输。在第二slot中，例如在大约第3个符号处LBT成功，从而在作为一个起始位置的符号4处接入上行免调度时域资源，进行长度为4个符号的PUSCH传输。
另一方面，在基于mini-slot的PUSCH调度的情况下，在一个slot中可以有多个mini-slot，因此，可以将UE配置为在多个mini-slot上传输PUSCH，以提高资源利用效率。换言之，在某一个起始位置接入之后，UE在确定单元102所确定的大小的上行免调度时域资源上进行PUSCH传输之后，还可以在该上行免调度时域资源之后的与该上行免调度时域资源具有相同大小的时频资源(可以认为是分配另外的上行免调度时域资源)上进行PUSCH传输。
例如，控制信息可以包括RRC信令中的SLIV字段(这里SLIV字段仅指示一个起始位置)，确定单元102基于该SLIV字段确定所述多个起始位置中的第一起始位置和上行免调度时域资源的大小，以及至少基于该第一起始位置和上行免调度时域资源的大小确定多个起始位置中的其他起始位置。
在一个示例中，确定单元102可以将一个时隙中在所述上行免调度时域资源之后的与上行免调度时域资源具有相同大小的时域资源确定为UE能够用于上行传输的时域资源，直到该一个时隙结束为止。该操作可以是默认执行的比如写在出厂设置中，也可以是由基站配置的。例如，确定单元102可以从第一起始位置起，每隔上行免调度时域资源的大小确定下一个起始位置，直到一个时隙结束，从而确定多个起始位置。UE在每一个起始位置起的具有上行免调度时域资源的大小的时域资源上传输PUSCH。
图6示出了一个时隙中分配多个PUSCH的示例。假设图6中通过SLIV设置的起始位置为符号{0}，且上行免调度时域资源的大小为4个符号，即，一个PUSCH传输所占用的长度为4个符号。确定单元102确定多个起始位置为{0,4,8,12}。在第一个slot中，由于LBT延迟了较长时间，UE接入的位置比较靠后，为符号{8}，因此只进行了一次PUSCH传输。在第二个slot中，UE在第0个符号处即接入上行免调度时域资源，在执行了4个符号的传输之后，可以继续以4个符号为单位执行两次PUSCH的传输，直到时隙结束。
在另一个示例中，确定单元102可以基于控制信息来确定一个时隙中在上述免调度时频资源之后还能够用于UE的上行传输的与上行免调度时域资源具有相同大小的时域资源的个数，并至少基于该个数来确定多个起始位置。例如，控制信息可以包括RRC信令或DCI中的新加字段，确定单元102被配置为基于该新加字段来确定该个数。
示例性地，新加比特可以包括在上述PUSCH-TimeDomainResourceAllocation中，如下所示：
Figure PCTCN2020107689-appb-000003
其中，repK0为新加的字段。仍然以图6为例，例如可以将repK0设置为2，如前所述，在第一个slot中，由于UE接入的位置比较靠后，因此在进行了一次PUSCH传输之后剩余的符号数不足以再次传输PUSCH，因此此时忽略repK0。在第二个slot中，根据该repK0，在执行了4个符号的PUSCH传输之后，继续执行两次4个符号的PUSCH传输。
应该理解，在上述上行免授权调度资源之后的与上行免调度时域资源具有相同大小的时域资源上，UE可以发送相同的传输块(Transport Block，TB)，也可以发送不同的TB。换言之，UE可以利用这些与上行免调度时域资源具有相同大小的时域资源重传相同的数据，也可以发送新的数据，这都不是限制性的。
可以看出，在存在多个初始位置的情况下，UE在哪个初始位置处接入上行免调度时域资源将取决于LBT执行的情况，因此，确定单元102还被配置为将实际接入的上行免调度时域资源的起始位置的信息包括在免调度上行控制信息(Configured Grant-Uplink Control Information，CG-UCI)中，以提供给基站。这样，基站可以通过CG-UCI来获知PUSCH的起始位置，从而正确地进行数据接收。
综上所述，根据本实施例的电子设备100能够在时域上的多个位置处尝试接入非授权频段的上行免调度时域资源，提高了接入的成功率，降低了非授权频段上的上行传输的时延。
<第二实施例>
图7示出了根据本申请的另一个实施例的电子设备200的功能模块框图，如图7所示，电子设备200包括：生成单元201，被配置为生成控制信息，该控制信息指示用户设备能够接入的非授权频段的上行免调度时域资源的多个起始位置；以及提供单元202，被配置为将控制信息提供给用户设备。
其中，生成单元201和提供单元202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。并且，应该理解，图7中所示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。
电子设备200例如可以设置在基站侧或者可通信地连接到基站。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，用户设备、其他基站等等)间的通信，这里不具体限制收发器的实现形式。
与第一实施例中类似地，控制信息可以指示一个时隙中作为多个起始位置的符号的位置。UE在控制信息所指示的多个起始位置之一接入上行免调度时域资源。
例如，控制信息可以包括比特图，比特图的每一位确定一个时隙中的每一个符号是否作为起始位置。可以通过将每一位设置为0或者1，来指示相应的符号是否作为起始位置。例如，当比特图为“01001001001000”时，指示符号{1,4,7,10}将作为起始位置，UE可以在这些符号处接入上行免调度时域资源。其中，比特图中的位的含义可以在基站和UE之间事先约定，也可以由基站进行限定并通过信令比如RRC信令来通知UE。
可替选地/作为补充，控制信息可以包括标记位，该标记位在取特定值时指示一个时隙中作为多个起始位置的特定符号的集合。例如，设置特定符号的集合(比如，符号1至10)作为多个起始位置，当标记位取预定值(比如1)时，指示该集合中的多个符号作为多个起始位置。此外，当控制信息包括多个标记位时，还可以使用多个标记位的不同取值来指示作为多个起始位置的不同的特定符号的集合。例如，在两个标记位的情况下，取值“00”对应于符号集合{0,3,5,7}而取值“01”对应于符号集合{1,4,8,10}，等等。采用这种方式，可以减小信令开销。
此外，控制信息可以包括RRC信令中的SLIV字段，用于指示一个时隙中作为多个起始位置的符号的位置。例如，SLIV字段的取值可以为SLIV字段的所有取值中先前未占用取值中的一个或多个。具体细节已在第一实施例中参照图4进行了描述，在此不再重复。
UE在控制信息所指示的多个起始位置之一接入上行免调度时域资源，在一个示例中，例如在基于slot的PUSCH调度中，UE可以使用该起始位置直至当前时隙结束时的时域资源进行PUSCH的传输。这样的配置可以是基站与UE默认的比如写在出厂设置中，也可以由基站比如通过RRC信令来配置。在基于mini-slot的PUSCH调度的情况下，控制信息例如还可以通过SLIV字段或控制信息的另外的部分来指示上行免调度时域资源的大小，以使得UE能够确定PUSCH传输能够占用的符号长度；或者，上行免调度时域资源的大小也可以是默认的。
在另一个示例中，例如在基于mini-slot的PUSCH调度中，UE可以被配置为在多个mini-slot上传输PUSCH，以提高资源利用效率。在这种情况下，例如，控制信息可以包括如下字段：该字段指示一个时隙中上行免调度时域资源之后还能够用于UE的上行传输的与上行免调度时域资源具有相同大小的时域资源的个数。控制信息可以包括RRC信令或DCI中的新加字段以用于指示该个数。例如，新加字段可以包括在RRC信令的PUSCH-TimeDomainResourceAllocation中。
替选地，UE可以使用一个时隙中在上行免调度时域资源之后的与上行免调度时域资源具有相同大小的时域资源来进行上行传输，直到该一个时隙结束为止。这样的配置可以是基站与UE默认的比如写在出厂设置中，也可以由基站比如通过RRC信令来配置。注意，这里也隐含确定了一个时隙中上行免调度时域资源之后还能够用于UE的上行传输的与 上行免调度时域资源具有相同大小的时域资源的个数。
例如，控制信息还可以包括SLIV字段，用于指示多个起始位置中的第一起始位置以及上行免调度时域资源的大小。此时的SLIV字段可以取SLIV字段的取值中先前已被占用的取值。通过结合第一起始位置、上行免调度时域资源的大小以及上述个数，控制信息指示了多个起始位置。相关具体细节已在第一实施例中参照图6进行了描述，在此不再重复。
例如，提供单元202可以经由RRC信令和DCI中的至少一个提供上述控制信息。
此外，如图7中的虚线框所示，电子设备200还可以包括：获取单元203，被配置为从UE获取CG-UCI，CG-UCI包括UE实际接入的上行免调度时域资源的起始位置的信息。
由于基站通过控制信息指示了多个初始位置，因此UE接入上行免调度资源的时域位置可以为这多个初始位置中的任何一个，但是基站并不能确定具体是哪一个。通过获取单元203的操作，基站能够获知UE在哪个初始位置处接入了上行免调度资源，从而确定应该从时隙的哪个符号处开始接收PUSCH。
在一个时隙中可分配多个PUSCH的情况下，获取单元203还被配置为在一个时隙中所述上行免调度资源之后的能够用于UE的上行传输的与上行免调度时域资源具有相同大小的时域资源的起始处进行监听。这样，基站可以正确地接收在上行免调度资源之后的与上行免调度时域资源具有相同大小的时域资源上传输的一个或多个PUSCH。
综上所述，根据本实施例的电子设备200使得UE能够在时域上的多个位置处尝试接入非授权频段的上行免调度时域资源，提高了UE接入的成功率，降低了非授权频段上的上行传输的时延。
<第三实施例>
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8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：获取来自基站的控制信息(S11)；以及基于该控制信息确定UE能够接入的非授权频段的上行免调度时域资源的多个起始位置(S21)。该方法例如可以在UE侧执行。

在另一个示例中，控制信息包括RRC信令中的SLIV字段，上述方法包括：基于该SLIV字段来确定一个时隙中作为多个起始位置的符号的位置。其中，SLIV字段的取值可以为SLIV字段的所有取值中先前未占用取值中的一个或多个。针对每一个起始位置，可以将上行免调度时域资源的大小确定为从该起始位置起至一个时隙结束的长度。
此外，还可以基于控制信息确定一个时隙中上行免调度时域资源之后还能够用于UE的上行传输的与上行免调度时域资源具有相同大小的时域资源的个数，并至少基于该个数确定多个起始位置。例如，控制信息包括RRC信令或DCI中的新加字段，基于该新加字段确定该个数。该新加字段例如包括在RRC信令的PUSCH-TimeDomainResourceAllocation中。
例如，控制信息可以包括RRC信令中的SLIV字段，基于该SLIV字段确定多个起始位置中的第一起始位置和上行免调度时域资源的大 小，以及至少基于第一起始位置和上行免调度时域资源的大小确定多个起始位置中的其他起始位置。
其中，在相同大小的时域资源上可以发送相同传输块或不同传输块。

图9示出了根据本申请的另一个实施例的用于无线通信的方法的流程图，该方法包括：生成控制信息，该控制信息指示UE能够接入的非授权频段的上行免调度时域资源的多个起始位置(S21)；以及将控制信息提供给UE(S22)。
在步骤S22中，可以经由RRC信令和DCI中的至少一个提供控制信息。
例如，控制信息指示一个时隙中作为多个起始位置的符号的位置。控制信息可以包括比特图，比特图的每一位确定一个时隙中的每一个符号是否作为起始位置。控制信息可以包括标记位，该标记位在取特定值时指示一个时隙中作为多个起始位置的特定符号的集合。
例如，控制信息包括RRC信令中的SLIV字段，用于指示一个时隙中作为多个起始位置的符号的位置。SLIV字段的取值可以为SLIV字段的所有取值中先前未占用取值中的一个或多个。
控制信息还可以包括如下字段：该字段指示一个时隙中上行免调度时域资源之后还能够用于UE的上行传输的与上行免调度时域资源具有相同大小的时域资源的个数。控制信息可以包括RRC信令或DCI中的新加字段以用于指示该个数。该新加字段例如包括在RRC信令的PUSCH-TimeDomainResourceAllocation中。此外，控制信息还可以包括SLIV字段，用于指示多个起始位置中的第一起始位置以及上行免调度时域资源的大小。
如图9中的虚线框所示，上述方法还可以包括步骤S23：从UE获取CG-UCI，该CG-UCI包括UE实际接入的上行免调度时域资源的起始位置的信息。此外，在步骤S23中，还可以在一个时隙中上行免调度资源之后的能够用于UE的上行传输的与上行免调度资源具有相同大小的时 域资源的起始处进行监听。
上述方法分别对应于第一实施例中所描述的装置100和第二实施例中所描述的装置200，其具体细节可参见以上相应位置的描述，在此不再重复。注意，上述各个方法可以结合或单独使用。
