Description

电子设备、无线通信方法和计算机可读存储介质
本申请要求于2020年8月5日提交中国专利局、申请号为202010776963.6、发明名称为“电子设备、无线通信方法和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
本公开的实施例总体上涉及无线通信领域,具体地涉及电子设备、无线通信方法和计算机可读存储介质。更具体地,本公开涉及一种作为无线通信系统中的网络侧设备的电子设备、一种作为无线通信系统中的用户设备的电子设备、一种由无线通信系统中的网络侧设备执行的无线通信方法、一种由无线通信系统中的用户设备执行的无线通信方法以及一种计算机可读存储介质。
背景技术
在基站设备的覆盖范围不足或者基站设备的信号不强的情况下,可以采用中继技术,即利用中继设备协助用户设备与基站设备之间的通信,从而扩大基站设备的覆盖范围。在中继技术中,可以用用户设备来实现中继设备。通常,承担转发工作的用户设备可以被称为中继用户设备,而无法直接与基站设备通信的用户设备可以被称为远端用户设备。也就是说,在下行链路传输中,中继用户设备可以将来自基站设备的信息转发至远端用户设备;在上行链路传输中,中继用户设备可以将来自远端用户设备的信息转发至基站设备。此外,可能出现在上行链路传输中需要中继用户设备而在下行链路传输中不需要中继用户设备、在下行链路传输中需要中继用户设备而在上行链路传输中不需要中继用户设备、或者在上行链路传输和下行链路传输中均需要中继用户设备的情形。
用户设备之间的链路可以被称为直通链路(SideLink,SL)。对于直通链路的资源分配方式,在模式1(mode 1)方式中,发送端的用户设备用于发送信息的资源由基站设备来决定。如上所述,在使用中继技术的无线通信系统中,远端用户设备与基站设备之间的链路被分成了两个部分:远端用户设备与中继用户设备之间的链路以及中继用户设备与基站设备 之间的链路。这样一来,基站设备需要分别指示两个部分的资源调度信息,由此使得数据传输的过程更加复杂,增加了数据传输的时延。
因此,有必要提出一种技术方案,以简化利用了中继技术的数据传输过程中的资源调度过程,从而减少时延。
发明内容
这个部分提供了本公开的一般概要,而不是其全部范围或其全部特征的全面披露。

根据本公开的另一方面,提供了一种由电子设备执行的无线通信方法,包括:接收下行控制信息DCI,所述DCI的尺寸与用于下行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同;以及根据所述DCI确定用于基站设备向所述电子设备发送数据的第一信道的调度信息和用于所述电子设备向远端用户设备转发所述数据的第二信道的调度信息。
根据本公开的另一方面,提供了一种由电子设备执行的无线通信方法,包括:生成下行控制信息DCI,所述DCI包括用于远端用户设备向中继用户设备发送数据的第一信道的调度信息和用于所述中继用户设备向所述电子设备转发所述数据的第二信道的调度信息,并且所述DCI的尺寸与用于上行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同;以及向所述远端用户设备发送生成的所述DCI。

提供了示例实施例,以便本公开将会变得详尽,并且将会向本领域技术人员充分地传达其范围。阐述了众多的特定细节如特定部件、装置和方法的例子,以提供对本公开的实施例的详尽理解。对于本领域技术人员而言将会明显的是,不需要使用特定的细节,示例实施例可以用许多不同的形式来实施,它们都不应当被解释为限制本公开的范围。在某些示例实施例中,没有详细地描述众所周知的过程、众所周知的结构和众所周知的技术。
将按照以下顺序进行描述:
1.场景的描述;
2.下行链路传输中网络侧设备的配置示例;
3.下行链路传输中用户设备的配置示例;
4.上行链路传输中网络侧设备的配置示例;
5.上行链路传输中用户设备的配置示例;
6.方法实施例;
7.应用示例。
<1.场景的描述>
图1是示出根据本公开的实施例的应用场景的示意图。如图1所示,基站设备经由中继UE(User Equipment,用户设备)执行与远端UE之间的传输。也就是说,在上行链路传输中,中继UE将来自远端UE的信息转发至基站设备;在下行链路传输中,中继UE将来自基站设备的信息转发至远端UE。
图2是示出现有技术中利用中继UE执行下行链路传输的信令流程图。如图2所示,在步骤S201中,基站用DCI格式1向中继UE发送用 于PDSCH(Physical Downlink Shared Channel,物理下行共享信道)的调度信息。接下来,在步骤S202中,基站利用PDSCH向中继UE发送针对远端UE的下行信息。接下来,在步骤S203中,中继UE向基站反馈针对PDSCH的反馈信息,包括ACK/NACK。接下来,在步骤S204中,基站用DCI格式3向中继UE发送用于PSSCH(Physical Sidelink Shared Channel,物理直通链路共享信道)的调度信息。接下来,在步骤S205和步骤S206中,中继UE分两个阶段向远端UE发送SCI(SideLink Control Information,直通链路控制信息)。接下来,在步骤S207中,中继UE根据接收到的PSSCH的调度信息利用PSSCH向远端UE转发来自基站的下行信息。接下来,在步骤S208中,远端UE向中继UE发送针对PSSCH的反馈信息,包括ACK/NACK。接下来,在步骤S209中,中继UE向基站转发针对PSSCH的反馈信息,包括ACK/NACK。
由此可见,在利用中继技术的下行链路传输中,基站在步骤S201和步骤S204中分别向中继UE发送了用于PDSCH和用于PSSCH的调度信息,从而使得下行链路传输过程变得复杂,增加了数据传输的时延。此外,中继UE需要对这两个调度信息进行解调,从而增加了中继UE的功耗。
值得注意的是,虽然在图1中示出了上行链路传输和下行链路传输均需要中继UE的情形,但是图1和图2主要为了说明下行链路传输的场景和信令流程,上行链路传输是否需要中继UE并不影响本公开的各个实施例。
图3是示出根据本公开的另一个实施例的应用场景的示意图。如图3所示,在上行链路传输中,中继UE将来自远端UE的信息转发至基站设备;在下行链路传输中,基站设备直接将信息发送至远端UE。
图4是示出现有技术中利用中继UE执行上行链路传输的信令流程图。如图4所示,在步骤S401中,基站利用DCI格式3向远端UE指示用于PSSCH的调度信息。在步骤S402和步骤S403中,远端UE分两个阶段向中继UE发送SCI。接下来,在步骤S404中,远端UE通过接收到的PSSCH的调度信息利用PSSCH向中继UE发送上行信息。接下来,在步骤S405中,中继UE向远端UE发送针对PSSCH的反馈信息,包括ACK/NACK。在步骤S406中,中继UE向基站发送调度请求。在步骤S407中,基站通过DCI格式0向中继UE指示用于PUSCH(Physical Uplink Shared Channel,物理上行共享信道)的调度信息。在步骤S408中,中继UE通过接收到的PUSCH的调度信息利用PUSCH向基站转发来自远端 UE的上行信息。
由此可见,在利用中继技术的上行链路传输中,基站在步骤S401向远端UE发送用于PSSCH的调度信息,并在步骤S407向中继UE发送用于PUSCH的调度信息,从而使得上行链路传输过程变得复杂,增加了数据传输的时延。
值得注意的是,虽然在图3中示出了上行链路传输需要中继UE而下行链路传输不需要中继UE的情形,但是图3和图4主要为了说明上行链路传输的场景和信令流程,下行链路传输是否需要中继UE并不影响本公开的各个实施例。
本公开针对这样的场景提出了一种无线通信系统中的电子设备、由无线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质,以简化利用了中继技术的数据传输过程中的资源调度过程,从而减少时延。
根据本公开的无线通信系统可以是5G NR(New Radio,新无线)通信系统。此外,根据本公开的无线通信系统可以包括TN(Terrestrial Network,地面网络),也可以包括NTN(Non-Terrestrial Network,非地面网络)和TN。
根据本公开的无线通信系统利用了中继技术,即在上行链路传输中,中继用户设备将来自远端用户设备的信息转发至基站设备;在下行链路传输中,中继用户设备将来自基站设备的信息转发至远端用户设备。
根据本公开的网络侧设备可以是基站设备,例如可以是eNB,也可以是gNB(第5代通信系统中的基站)。此外,根据本公开的网络侧设备可以是地面的网络侧设备,也可以是位于卫星设备上的网络侧设备。
根据本公开的用户设备可以是移动终端(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)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(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)。
进一步,在本公开中,DCI格式0(DCI format 0)用于上行链路调度,因此也被称为用于上行链路调度的DCI格式,DCI格式0包括但不限于DCI格式0_0、DCI格式0_1和DCI格式0_2;DCI格式1(DCI format  1)用于下行链路调度,因此也被称为用于下行链路调度的DCI格式,DCI格式1包括但不限于DCI格式1_0、DCI格式1_1和DCI格式1_2;DCI格式3(DCI format 3)用于直通链路调度,因此也被称为用于直通链路调度的DCI格式,DCI格式3包括但不限于DCI格式3_0和DCI格式3_1。此外,在本公开中,PUSCH指的是用户设备与基站设备之间用于传输上行数据的信道,PDSCH指的是用户设备与基站设备之间用于传输下行数据的信道,PSSCH指的是用户设备之间用户传输上行数据和下行数据的信道,PSFCH指的是用户设备之间的用于发送针对PSSCH的反馈信息的信道。
<2.下行链路传输中网络侧设备的配置示例>
图5是示出根据本公开的实施例的电子设备500的配置的示例的框图。这里的电子设备500可以作为无线通信系统中的网络侧设备,具体地可以作为无线通信系统中的基站设备。下面将描述在下行链路传输中电子设备500的配置。
如图5所示,电子设备500可以包括生成单元510和通信单元520。
这里,电子设备500的各个单元都可以包括在处理电路中。需要说明的是,电子设备500既可以包括一个处理电路,也可以包括多个处理电路。进一步,处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是,这些功能单元可以是物理实体或逻辑实体,并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例,生成单元510可以生成DCI。该DCI包括用于下行链路传输的调度信息。具体地,该DCI包括用于电子设备500向中继用户设备发送数据的第一信道的调度信息和用于中继用户设备向远端用户设备转发数据的第二信道的调度信息。
根据本公开的实施例,生成单元510生成的DCI的尺寸与用于下行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同。
根据本公开的实施例,电子设备500可以通过通信单元520向中继用户设备发送生成单元510生成的DCI。
由此可见,根据本公开的实施例的电子设备500,可以向中继用户设备发送用于下行链路传输的DCI,其可以包括用于电子设备500向中继用户设备发送数据的第一信道的调度信息和用于中继用户设备向远端用户 设备转发数据的第二信道的调度信息。这样一来,电子设备500只需要发送一次DCI就可以同时指示两个信道的调度信息,从而简化了资源调度过程,减少了数据传输的时延。进一步,中继用户设备只需要进行一次解调就可以获得两个信道的资源调度信息,可以降低中继用户设备的功耗。
众所周知,中继用户设备在接收到DCI之后需要对承载DCI的PDCCH(Physical Downlink Control Channel,物理下行控制信道)进行盲检,即利用不同的RNTI(Radio Network Tempory Identity,无线网络临时标识)和不同的DCI格式的尺寸对接收到的DCI进行解码。因此,DCI格式的尺寸的个数会影响中继用户设备的盲检的复杂度。根据本公开的实施例,由于生成单元510生成的DCI的尺寸与用于下行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同,因此没有引入新的DCI格式的尺寸,从而不会增加中继用户设备的盲检的复杂度。
根据本公开的实施例,第一信道为PDSCH,第二信道为PSSCH。
下面将描述根据本公开的实施例的生成单元510在生成用于下行链路传输的调度的DCI时的配置。
根据本公开的实施例,生成单元510可以生成DCI以包括:用于下行链路调度的DCI格式的字段;以及直通链路调度的DCI格式的字段中的不与用于下行链路调度的DCI格式相同的字段。
这里,用于下行链路调度的DCI格式指的是包括基站设备与用户设备之间的下行链路的调度信息的DCI格式,例如DCI格式1,包括但不限于DCI格式1_0、DCI格式1_1、DCI格式1_2。也就是说,用户设备可以根据用于下行链路调度的DCI格式确定PDSCH的接收。
DCI格式1_1的内容如下表所示。
表1
Figure PCTCN2021109110-appb-000001
Figure PCTCN2021109110-appb-000002
Figure PCTCN2021109110-appb-000003
这里,直通链路调度的DCI格式指的是包括用户设备之间的直通链路的调度信息的DCI格式,例如DCI格式3,包括但不限于DCI格式3_0、DCI格式3_1。也就是说,接收侧用户设备可以根据用于直通链路调度的DCI格式确定PSSCH的接收。
DCI格式3_0的内容如下表所示。
表2
Figure PCTCN2021109110-appb-000004
如上以示例性的方式示出了DCI格式1_1和DCI格式3_0的必要字段,其它一些非必要的字段并未示出。此外,这些示例也不是限制性的, 随着技术的发展,DCI格式1_1和DCI格式3_0还可能包括其它必要的字段。
根据本公开的实施例,生成单元510生成的DCI包括用于下行链路调度的DCI格式的全部必要的字段和用于直通链路调度的DCI格式的全部必要的字段。而针对用于下行链路调度的DCI格式的全部必要的字段与用于直通链路调度的DCI格式的全部必要的字段中相同的字段,生成的DCI中可以只包括一个。以用于下行链路调度的DCI格式为DCI格式1_1并且用于直通链路调度的DCI格式为DCI格式3_0为例,在DCI格式1_1和DCI格式3_0中都有字段“新数据指示”和字段“HARQ进程编号”,因此生成单元510生成的DCI可以仅包括一个字段“新数据指示”和一个字段“HARQ进程编号”。
根据本公开的实施例,由于生成单元510生成的包括两个信道的调度信息的DCI包括用于下行链路调度的DCI格式的全部必要的字段和用于直通链路调度的DCI格式的全部必要的字段,因此新的DCI格式的尺寸大于用于下行链路调度的DCI格式的尺寸和用于直通链路调度的DCI格式的尺寸。
根据本公开的实施例,生成单元510在生成用于下行链路调度的DCI格式时,可以将用于下行链路调度的DCI格式补零以使得用于下行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同。这里的用于下行链路调度的DCI格式为DCI格式1,包括但不限于DCI格式1_0、DCI格式1_1、DCI格式1_2。
根据本公开的实施例,生成单元510可以将用于下行链路调度的DCI格式中的一个或多个格式补零以使得用于下行链路调度的DCI格式中的一个或多个格式的尺寸与生成的新的DCI的尺寸相同。例如,生成单元510可以将DCI格式1_1补零以使得DCI格式1_1的尺寸与新的DCI的尺寸相同。再如,生成单元510可以将DCI格式1_1和DCI格式1_0都补零以使得DCI格式1_1和DCI格式1_0的尺寸都与新的DCI的尺寸相同。
根据本公开的实施例,如图5所示,电子设备500还可以包括编码单元530,用于利用RNTI对生成的新的DCI进行加扰。
目前的RNTI包括两种:用于上下行链路的RNTI和用于直通链路的RNTI。用于上下行链路的RNTI主要用于对用于上行链路调度的DCI格 式进行加扰和用于下行链路调度的DCI格式进行加扰,即用于对DCI格式0和DCI格式1进行加扰。用于直通链路的RNTI主要用于对用于直通链路调度的DCI格式进行加扰,即用于对DCI格式3进行加扰。
根据本公开的实施例,在生成单元510将用于下行链路调度的DCI格式补零以使得用于下行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同的情况下,编码单元530可以利用用于上下行链路的RNTI对生成的新的DCI进行加扰。
根据本公开的实施例,用于上下行链路的RNTI包括但不限于C-RNTI(Cell-RNTI,小区RNTI)、CS-RNTI(Configured Scheduling-RNTI,配置调度RNTI)和MCS-C-RNTI(该RNTI是用于指示PDSCH和PUSCH的可选MCS表的唯一的用户设备标识)。
如前文所述,RNTI的格式和DCI格式的尺寸的个数会影响中继用户设备的盲检的复杂度。目前,用于上下行链路的RNTI进行加扰的DCI格式有三个尺寸:DCI格式1_0和DCI格式0_0的尺寸;DCI格式1_1和DCI格式0_1的尺寸;以及DCI格式1_2和DCI格式0_2的尺寸。根据本公开的实施例,在生成单元510生成的新的DCI的尺寸与用于下行链路调度的DCI格式中的一个格式的尺寸相同的情况下,用于上下行链路的RNTI进行加扰的DCI格式的尺寸的数目还是三个,从而不会增加中继用户设备的盲检的复杂度。根据本公开的实施例,在生成单元510生成的新的DCI的尺寸与用于下行链路调度的DCI格式中的多个格式的尺寸相同的情况下,用于上下行链路的RNTI进行加扰的DCI格式的尺寸的数目少于三个,从而进一步降低中继用户设备的盲检的复杂度。
根据本公开的实施例,生成单元510在生成用于直通链路调度的DCI格式时,可以将用于直通链路调度的DCI格式补零以使得用于直通链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同。这里的用于直通链路调度的DCI格式为DCI格式3,包括但不限于DCI格式3_0、DCI格式3_1。
根据本公开的实施例,生成单元510可以将用于直通链路调度的DCI格式中的一个或多个格式补零以使得用于直通链路调度的DCI格式中的一个或多个格式的尺寸与生成的新的DCI的尺寸相同。例如,生成单元510可以将DCI格式3_1补零以使得DCI格式3_1的尺寸与新的DCI的尺寸相同。再如,生成单元510可以将DCI格式3_1和DCI格式3_0都补零以使得DCI格式3_1和DCI格式3_0的尺寸都与新的DCI的尺寸相 同。
根据本公开的实施例,在生成单元510将用于直通链路调度的DCI格式补零以使得用于下直通链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同的情况下,编码单元530可以利用用于直通链路的RNTI对生成的新的DCI进行加扰。
根据本公开的实施例,用于直通链路的RNTI包括但不限于SL-RNTI(SideLink-RNTI,直通RNTI)和SL-L-CS-RNTI(SideLink-LTE-Configured Scheduling-RNTI,直通LTE配置调度RNTI)。
如前文所述,根据本公开的实施例,在生成单元510生成的新的DCI的尺寸与用于直通链路调度的DCI格式中的一个或多个格式的尺寸相同的情况下,用于直通链路的RNTI进行加扰的DCI格式的尺寸的数目不变或更少,从而不会增加或者可以降低中继用户设备的盲检的复杂度。
根据本公开的实施例,编码单元530也可以利用与用于上下行链路的RNTI和用于直通链路的RNTI不同的RNTI对生成的新的DCI进行加扰。也就是说,编码单元530生成一种专用于对这种包括两个信道的调度信息的用于下行调度的DCI进行加扰的RNTI。
根据本公开的实施例,中继用户设备可能支持两个TB(Transport Block,传输块)同时调度。如表1所示,DCI格式1_1中可以包括针对TB1的信息和针对TB2的信息,每个TB的信息包括但不限于调制编码方式、新数据指示和冗余版本。根据本公开的实施例,生成单元510在生成新的DCI时可以增加用于表示TB指示信息的字段,TB指示信息指示用于中继用户设备的两个TB分别用于第一信道和第二信道。也就是说,TB指示信息可以指示两个TB中的哪个TB用于第一信道,哪个TB用于第二信道。例如,TB指示信息可以包括1比特的信息,当TB指示信息为0时表示TB1用于第一信道而TB2用于第二信道;当TB指示信息为1时表示TB1用于第二信道而TB2用于第一信道。
根据本公开的实施例,生成单元510生成的新的DCI也可以隐性地表示TB指示信息。例如,电子设备500和中继用户设备事先约定TB1用于第一信道而TB2用于第二信道,或者约定TB1用于第二信道而TB2用于第一信道。
如上所述,根据本公开的实施例,生成单元510可以对用于下行链路调度的DCI格式进行补零以使得用于下行链路调度的DCI格式的尺寸 与新生成的DCI的尺寸相同,或者对用于直通链路调度的DCI格式进行补零以使得用于直通链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。这样一来,可以在不增加中继用户设备的盲检复杂度的同时简化中继过程的操作并降低数据传输的时延。
根据本公开的实施例,生成单元510还可以生成新的DCI以包括用于下行链路调度的DCI格式的字段,以使得用于下行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同。进一步,生成单元510可以利用用于下行链路调度的DCI格式的部分字段来表示第一信道的调度信息,并且利用用于下行链路调度的DCI格式的其它字段来表示第二信道的调度信息。
也就是说,生成单元510可以复用用于下行链路调度的DCI格式中的一些字段来表示用于第二信道的调度信息。这里,可以表示用于第二信道的调度信息中的必要信息,包括但不限于用于第二信道的时域资源和频域资源。例如,生成单元510可以将DCI格式1_1中的字段“优先级指示”、“信道接入-CPext”、“最小适用调度偏移指示”、“辅小区睡眠指示”分别表示DCI格式3_0中的字段“时间空隙”、“初始传输分配的子信道的最低索引”、“SCI格式0-1字段:频域资源分配”和“SCI格式0-1字段:时域资源分配”。当然,上述示例并不是限制性的,生成单元510也可以复用用于下行链路调度的DCI格式中的其它字段。
根据本公开的实施例,生成单元510还可以利用指示信息来指示上述复用。例如,生成单元510可以利用新的字段来表示该指示信息。可选地,生成单元510也可以利用用于下行链路调度的DCI格式中的一些字段来表示上述指示信息。例如,当针对一个TB的参数均为1时,中继用户设备可以确定用于下行链路调度的DCI格式中的一些字段被用来表示用于第二信道的调度信息,不再表示原有的含义。
根据本公开的实施例,由于用于下行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同,因此,编码单元530可以利用用于上下行链路的RNTI对生成的新的DCI进行加扰。这样一来,用于上下行链路的RNTI进行加扰的DCI格式的尺寸的数目还是三个,从而不会增加中继用户设备的盲检的复杂度。
如上所述,根据本公开的实施例,生成单元510可以复用用于下行链路调度的DCI格式中的一些字段来表示第二信道的信息,以使得用于下行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。这样一来, 可以在不增加中继用户设备的盲检复杂度的同时简化中继过程的操作并降低数据传输的时延。
图6是示出根据本公开的实施例的利用中继UE执行下行链路传输的信令流程图。如图6所示,在步骤S601中,基站向中继UE发送DCI,包括用于PDSCH的调度信息和用于PSSCH的调度信息。接下来,在步骤S602中,基站根据用于PDSCH的调度信息向中继UE发送数据。接下来,在步骤S603和步骤S604中,中继UE分两个阶段向远端UE发送SCI。接下来,在步骤S605中,中继UE根据用于PSSCH的调度信息向远端UE转发数据。由此,基站只需要向中继UE发送一次DCI就可以指示两个信道的调度信息,中继UE只需要进行一次解调就可以获取两个信道的调度信息。
如图5所示,根据本公开的实施例,电子设备500还可以包括处理单元540,用于处理来自中继用户设备的反馈信息。这里,反馈信息可以包括:中继用户设备对第一信道的第一反馈信息和远端用户设备对第二信道的第二反馈信息。
根据本公开的实施例,用于下行链路传输的DCI格式可以包括用于PDSCH的反馈时间,即指示中继用户设备针对接收到的来自基站设备的PDSCH的反馈信息的发送时间。例如,表1中所示的字段“PDSCH-to-HARQ_反馈时机指示”可以表示用于PDSCH的反馈时间。用于直通链路传输的DCI格式可以包括用于PSFCH(Physical Sidelink Feedback Channel物理直通反馈信道)的反馈时间,即指示接收侧的用户设备针对接收到的来自发送侧的用户设备的PSSCH的反馈信息的发送时间。例如表2中所示的字段“PSFCH-to-HARQ反馈时机指示”可以表示用于PSFCH的反馈时间。
根据本公开的实施例,生成单元510生成的新的DCI可以仅包括用于PSFCH的反馈时间而不包括用于PDSCH的反馈时间,也可以包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者。
根据本公开的实施例,在新的DCI仅包括用于PSFCH的反馈时间的情况下,当中继用户设备没有成功接收来自电子设备500的数据的情况下,电子设备500可以在用于PSFCH的反馈时间从中继用户设备接收第一反馈信息和第二反馈信息。在这种情况下,中继用户设备可以不向远端用户设备转发该数据,而是直接在用于PSFCH的反馈时间向电子设备500反馈。这里,由于中继用户设备没有成功接收来自电子设备500的数据, 因此第一反馈信息可以为NACK,而中继用户设备没有向远端用户设备转发数据,因此第二反馈信息也可以为NACK。
根据本公开的实施例,电子设备500可以在用于PSFCH的反馈时间从中继用户设备接收压缩后的第一反馈信息和第二反馈信息,例如第一反馈信息和第二反馈信息被压缩为NACK。可选地,电子设备500也可以在用于PSFCH的反馈时间从中继用户设备接收非压缩的第一反馈信息和第二反馈信息,例如第一反馈信息为NACK,第二反馈信息也为NACK。也就是说,中继用户设备可以一次性上报关于两个信道的反馈信息。
图7是示出根据本公开的实施例的利用中继UE执行下行链路传输的信令流程图。在图7所示的示例中,新的DCI仅包括用于PSFCH的反馈时间,并且中继UE没有成功接收来自基站的数据。如图7所示,在步骤S701中,基站向中继UE发送DCI,DCI包括用于PDSCH的调度信息和用于PSSCH的调度信息。接下来,在步骤S702中,基站根据用于PDSCH的调度信息向中继UE发送PDSCH。接下来,由于中继UE没有成功接收PDSCH,因此不对数据进行转发,而是步骤S703中,在用于PSFCH的反馈时间向基站发送反馈信息,例如包括压缩形式的NACK,或者非压缩形式的NACK和NACK。
根据本公开的实施例,在新的DCI仅包括用于PSFCH的反馈时间的情况下,当中继用户设备成功接收来自电子设备500的数据的情况下,中继用户设备可以根据DCI中包括的第二信道的调度信息向远端用户设备转发数据。进一步,电子设备500可以在用于PSFCH的反馈时间从中继用户设备接收第一反馈信息和第二反馈信息。
这里,中继用户设备可以生成第一反馈信息,例如包括ACK。此外,中继用户设备可以从远端用户设备接收远端用户设备针对第二信道的第二反馈信息,包括ACK或者NACK。
根据本公开的实施例,电子设备500可以在用于PSFCH的反馈时间从中继用户设备接收压缩后的第一反馈信息和第二反馈信息。例如,在远端用户设备上报的第二反馈信息为ACK的情况下,第一反馈信息和第二反馈信息可以被压缩为ACK;在远端用户设备上报的第二反馈信息为NACK的情况下,第一反馈信息和第二反馈信息可以被压缩为NACK。可选地,电子设备500也可以在用于PSFCH的反馈时间从中继用户设备接收非压缩的第一反馈信息和第二反馈信息,例如第一反馈信息为ACK,第二反馈信息为ACK或者NACK。也就是说,中继用户设备可以一次性 上报关于两个信道的反馈信息。
如上所述,中继用户设备可以在用于PSFCH的反馈时间向电子设备500反馈第一反馈信息和第二反馈信息。这样一来,中继用户设备不需要先反馈第一反馈信息再进行数据转发,而是先进行数据转发再反馈第一反馈信息和第二反馈信息,从而降低了向远端用户设备的数据传输的时延。
图8是示出根据本公开的实施例的利用中继UE执行下行链路传输的信令流程图。在图8所示的示例中,新的DCI仅包括用于PSFCH的反馈时间,并且中继UE成功接收来自基站的数据。如图8所示,在步骤S801中,基站向中继UE发送DCI,指示用于PDSCH的调度信息和用于PSSCH的调度信息。接下来,在步骤S802中,基站根据用于PDSCH的调度信息向中继UE发送PDSCH。假定中继UE成功接收来自基站的数据。在步骤S803和步骤S804中,中继UE分两个阶段向远端UE发送SCI。接下来,在步骤S805中,中继UE根据用于PSSCH的调度信息向远端UE发送PSSCH。接下来,在步骤S806中,根据PSSCH的接收结果,远端UE向中继UE发送反馈信息。例如,在成功接收PSSCH的情况下,反馈ACK;在没有成功接收PSSCH的情况下,反馈NACK。接下来,在步骤S807中,在用于PSFCH的反馈时间中继UE向基站发送反馈信息,包括非压缩的ACK和ACK/NACK,或者压缩的ACK/NACK。
如上所述,根据本公开的实施例,在新的DCI仅包括用于PSFCH的反馈时间的情况下,电子设备500可以在用于PSFCH的反馈时间从中继UE接收针对第一信道的第一反馈信息和针对第二信道的第二反馈信息。
根据本公开的实施例,在新的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者的情况下,电子设备500可以在用于PDSCH的反馈时间从中继用户设备接收第一反馈信息,并且在用于PSFCH的反馈时间从中继用户设备接收第二反馈信息。
根据本公开的实施例,在新的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者的情况下,如果中继用户设备没有成功接收来自电子设备500的数据,则第一反馈信息可以为NACK。进一步,中继用户设备可以不向远端用户设备转发数据,因此第二反馈信息也可以为NACK。
图9是示出根据本公开的实施例的利用中继UE执行下行链路传输的信令流程图。在图9中,新的DCI包括用于PSFCH的反馈时间和用于 PDSCH的反馈时间两者,并且中继UE没有成功接收来自基站的数据。如图9所示,在步骤S901中,基站向中继UE发送DCI,指示用于PDSCH的调度信息和用于PSSCH的调度信息。接下来,在步骤S902中,基站根据用于PDSCH的调度信息向中继UE发送PDSCH。这里假定中继UE没有成功接收来自基站的数据,则不向远端UE转发数据,而是在步骤S903中,在用于PDSCH的反馈时间向基站发送第一反馈信息,例如NACK。在步骤S904中,在用于PSFCH的反馈时间中继UE向基站发送第二反馈信息,例如NACK。
根据本公开的实施例,在新的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者的情况下,如果中继用户设备没有成功接收来自电子设备500的数据,中继用户设备可以在用于PDSCH的反馈时间向电子设备500发送第一反馈信息。进一步,如果用于PSFCH的反馈时间比较远,则中继用户设备也可以等待电子设备500的重传数据,并且在成功接收重传数据的情况下向远端用户设备转发重传数据,并根据远端用户设备对重传数据的接收结果在用于PSFCH的反馈时间反馈第二反馈信息。
图10是示出根据本公开的实施例的利用中继UE执行下行链路传输的信令流程图。在图10中,新的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者,并且中继UE没有成功接收来自基站的初传数据而是成功接收来自基站的重传数据。如图10所示,在步骤S1001中,基站向中继UE发送DCI,指示用于PDSCH的调度信息和用于PSSCH的调度信息。接下来,在步骤S1002中,基站根据用于PDSCH的调度信息向中继UE发送PDSCH。这里假定中继UE没有成功接收来自基站的数据,则在步骤S1003中,中继UE在用于PDSCH的反馈时间向基站发送第一反馈信息,例如NACK。接下来,在步骤S1004中,基站向中继UE重传PDSCH。接下来,在步骤S1005中,中继UE在用于PDSCH的反馈时间向基站发送第一反馈信息,例如ACK。在步骤S1006和步骤S1007中,中继UE分两个阶段向远端UE发送SCI。在步骤S1008中,中继UE根据用于PSSCH的调度信息向远端UE转发重传的数据。在步骤S1009中,远端UE根据对重传数据的接收结果向中继UE发送针对PSSCH的反馈信息,包括ACK或者NACK。在步骤S1010中,中继UE在用于PSFCH的反馈时间向基站发送第二反馈信息,包括ACK或者NACK。
根据本公开的实施例,在新的DCI包括用于PSFCH的反馈时间和用 于PDSCH的反馈时间两者的情况下,如果中继用户设备成功接收来自电子设备500的数据,则中继用户设备可以在用于PDSCH的反馈时间向电子设备500发送第一反馈信息,例如可以为ACK,并且可以在用于PSFCH的反馈时间向电子设备500发送第二反馈信息,例如可以为ACK/NACK。
图11是示出根据本公开的实施例的利用中继UE执行下行链路传输的信令流程图。在图11中,新的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者,并且中继UE成功接收来自基站的数据。如图11所示,在步骤S1101中,基站向中继UE发送DCI,指示用于PDSCH的调度信息和用于PSSCH的调度信息。接下来,在步骤S1102中,基站根据用于PDSCH的调度信息向中继UE发送PDSCH。这里假定中继UE成功接收来自基站的数据,则在步骤S1103中,中继UE在用于PDSCH的反馈时间向基站发送第一反馈信息,例如ACK。接下来,在步骤S1104和步骤S1105中,中继UE分两个阶段向远端UE发送SCI。在步骤S1106中,中继UE根据用于PSSCH的调度信息向远端UE转发数据。在步骤S1107中,远端UE根据对数据的接收结果向中继UE发送针对PSSCH的反馈信息,包括ACK或者NACK。在步骤S1108中,中继UE在用于PSFCH的反馈时间向基站发送第二反馈信息,包括ACK或者NACK。
如上所述,根据本公开的实施例,在新的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间两者的情况下,电子设备500可以在用于PDSCH的反馈时间从中继用户设备接收第一反馈信息,并且在用于PSFCH的反馈时间从中继用户设备接收第二反馈信息。
由此可见,根据本公开的实施例,电子设备500只需要发送一次DCI就可以同时指示两个信道的调度信息,中继用户设备只需要进行一次解调就可以获得两个信道的资源调度信息,可以降低中继用户设备的功耗。此外,电子设备500可以对用于下行链路调度的DCI格式进行补零以使得用于下行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同,或者对用于直通链路调度的DCI格式进行补零以使得用于直通链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。可选地,生成单元510可以复用用于下行链路调度的DCI格式中的一些字段来表示第二信道的信息,以使得用于下行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。进一步,在新的DCI仅包括用于PSFCH的反馈时间的情况下,电子设备500可以在用于PSFCH的反馈时间从中继UE接收针对第一信道的第一反馈信息和针对第二信道的第二反馈信息;在新的DCI包括用于PSFCH的反 馈时间和用于PDSCH的反馈时间两者的情况下,电子设备500可以在用于PDSCH的反馈时间从中继用户设备接收第一反馈信息,并且在用于PSFCH的反馈时间从中继用户设备接收第二反馈信息。总之,根据本公开的实施例的电子设备500,可以在不增加中继用户设备的盲检复杂度的同时简化资源调度过程并减少数据传输的时延。
<3.下行链路传输中用户设备的配置示例>
图12是示出根据本公开的实施例的无线通信系统中的用作用户设备的电子设备1200的结构的框图。下面将描述在下行链路传输中用作中继用户设备的电子设备1200的配置。
如图12所示,电子设备1200可以包括通信单元1210和确定单元1220。
这里,电子设备1200的各个单元都可以包括在处理电路中。需要说明的是,电子设备1200既可以包括一个处理电路,也可以包括多个处理电路。进一步,处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是,这些功能单元可以是物理实体或逻辑实体,并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例,电子设备1200可以通过通信单元1210从基站设备接收DCI,DCI的尺寸与用于下行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同。
根据本公开的实施例,确定单元1220可以根据接收到的DCI确定用于基站设备向电子设备1200发送数据的第一信道的调度信息和用于电子设备1200向远端用户设备转发数据的第二信道的调度信息。
如上所述,根据本公开的实施例,电子设备1200进行一次解调就可以获得两个信道的资源调度信息,可以降低电子设备1200的功耗,简化中继传输过程,并减小向远端用户设备转发数据的时延。
根据本公开的实施例,电子设备1200可以根据第一信道的调度信息从基站设备接收数据。例如,电子设备1200可以根据第一信道的调度信息确定来自基站设备的数据所占用的时频资源。进一步,电子设备1200可以根据第二信道的调度信息向远端用户设备转发数据。例如,电子设备1200可以根据第二信道的调度信息确定向远端用户设备转发数据的时频资源。
根据本公开的实施例,第一信道为PDSCH,第二信道为PSSCH。
根据本公开的实施例,电子设备1200接收到的DCI可以包括用于下行链路调度的DCI格式的字段;以及用于直通链路调度的DCI格式的字段中的不与用于下行链路调度的DCI格式相同的字段。
根据本公开的实施例,确定单元1220可以根据用于下行链路调度的DCI格式的字段确定第一信道的调度信息,并且可以根据用于直通链路调度的DCI格式的字段中的不与用于下行链路调度的DCI格式相同的字段来确定第二信道的调度信息。
根据本公开的实施例,如图12所示,电子设备1200还可以包括解码单元1230,用于利用RNTI对DCI进行解扰。
根据本公开的实施例,解码单元1230可以利用用于上下行链路的RNTI、用于直通链路的RNTI、或者与用于上下行链路的RNTI和用于直通链路的RNTI不同的RNTI对DCI进行解扰。
进一步,根据本公开的实施例,在解码单元1230利用用于上下行链路的RNTI对DCI成功解扰的情况下,确定单元1220可以进一步确定没有进行补零的DCI为包括两个信道的调度信息的DCI,而进行了补零的DCI为用于下行链路调度的DCI。根据本公开的实施例,在解码单元1230利用用于直通链路的RNTI对DCI成功解扰的情况下,确定单元1220可以进一步确定没有进行补零的DCI为包括两个信道的调度信息的DCI,而进行了补零的DCI为用于直通链路调度的DCI。在解码单元1230利用与用于上下行链路的RNTI和用于直通链路的RNTI不同的RNTI对DCI成功解扰的情况下,确定单元1220可以直接确定该DCI为包括两个信道的调度信息的DCI。
如上所述,根据本公开的实施例,用于下行链路调度的DCI格式的尺寸与新的DCI的尺寸相同,或者用于直通链路调度的DCI格式的尺寸与新的DCI的尺寸相同,从而电子设备1200在进行盲检时不会增加复杂度。
根据本公开的实施例,确定单元1220还可以根据DCI中包括的TB指示信息确定用于电子设备1200的两个TB分别用于第一信道和第二信道。例如,确定单元1220可以根据DCI中包括的用于TB指示信息的字段确定TB指示信息。此外,电子设备1200也可以与网络侧设备约定两个TB中的哪个TB用于第一信道哪个TB用于第二信道。
根据本公开的实施例,接收到的DCI可以包括用于下行链路调度的 DCI格式的字段。
根据本公开的实施例,确定单元1220可以根据用于下行链路调度的DCI格式的部分字段确定第一信道的调度信息,并根据用于下行链路调度的DCI格式的其它字段确定第二信道的调度信息。
根据本公开的实施例,解码单元1230可以利用用于上下行链路的RNTI和用于直通链路的RNTI对DCI进行解扰。进一步,在解码单元1230利用用于上下行链路的RNTI对DCI成功解扰的情况下,确定单元1220可以根据DCI中的指示该DCI是否为新的包括两个信道的调度信息的DCI的字段来确定该DCI是新的包括两个信道的调度信息的DCI还是用于下行链路调度的DCI。
例如,当包括上述指示的字段为1时,确定单元1220可以确定用于下行链路调度的DCI格式中的一些字段被用来表示用于第二信道的调度信息,不再表示原有的含义。可选地,也可以利用用于下行链路调度的DCI中的原有字段来表示上述指示。例如,当DCI中针对一个TB的参数均为1时,确定单元1220可以确定用于下行链路调度的DCI格式中的一些字段被用来表示用于第二信道的调度信息,不再表示原有的含义。作为一个示例,确定单元1220可以将DCI格式1_1中的字段“优先级指示”、“信道接入-CPext”、“最小适用调度偏移指示”、“辅小区睡眠指示”分别理解为字段“时间空隙”、“初始传输分配的子信道的最低索引”、“SCI格式0-1字段:频域资源分配”和“SCI格式0-1字段:时域资源分配”的含义。也就是说,确定单元1220可以根据上述字段来确定第二信道的调度信息。当然,上述示例并不是限制性的,用于下行链路调度的DCI中的其他字段也可能被复用。
如上所述,根据本公开的实施例,用于下行链路调度的DCI格式的尺寸与新的DCI的尺寸相同,从而电子设备1200在进行盲检时不会增加复杂度。
根据本公开的实施例,如图12所示,电子设备1200还可以包括反馈单元1240,用于生成向基站设备发送反馈信息,反馈信息可以包括电子设备1200对第一信道的第一反馈信息和远端用户设备对第二信道的第二反馈信息。
根据本公开的实施例,在接收到的DCI仅包括用于PSFCH的反馈时间的情况下,确定单元1220可以根据DCI确定用于PSFCH的反馈时间。 进一步,电子设备1200可以在用于PSFCH的反馈时间向基站设备发送第一反馈信息和第二反馈信息。
根据本公开的实施例,如果电子设备1200没有成功接收来自基站设备的数据,那么电子设备1200可以不向远端用户设备转发数据。在这种情况下,第一反馈信息为NACK,第二反馈信息也可以为NACK。这里,反馈单元1240可以对第一反馈信息和第二反馈信息进行压缩,从而在用于PSFCH的反馈时间发送压缩后的NACK。可选地,反馈单元1240也可以不对第一反馈信息和第二反馈信息进行压缩,从而在用于PSFCH的反馈时间发送NACK和NACK。
根据本公开的实施例,如果电子设备1200成功接收来自基站设备的数据,那么电子设备1200可以利用DCI中用于第二信道的调度信息向远端用户设备转发数据。在这种情况下,第一反馈信息为ACK,并且反馈单元1240可以根据来自远端用户设备的反馈信息确定第二反馈信息为ACK或者NACK。这里,反馈单元1240可以对第一反馈信息和第二反馈信息进行压缩,从而在第二反馈信息为ACK的情况下在用于PSFCH的反馈时间发送压缩后的ACK,并且在第二反馈信息为NACK的情况下在用于PSFCH的反馈时间发送压缩后的NACK。可选地,反馈单元1240也可以不对第一反馈信息和第二反馈信息进行压缩,从而在用于PSFCH的反馈时间发送ACK和ACK/NACK。
如上所述,根据本公开的实施例,电子设备1200可以先向远端用户设备转发数据,然后在用于PSFCH的反馈时间向基站设备发送第一反馈信息和第二反馈信息,从而减少向远端用户设备转发数据的时延。
根据本公开的实施例,在接收到的DCI包括用于PSFCH的反馈时间和用于PDSCH的反馈时间的情况下,确定单元1220可以根据DCI确定用于PDSCH的反馈时间和用于PSFCH的反馈时间。进一步,电子设备1200可以在用于PDSCH的反馈时间向基站设备发送第一反馈信息,并且在用于PSFCH的反馈时间向基站设备发送第二反馈信息。
根据本公开的实施例,如果电子设备1200没有成功接收来自基站设备的数据,那么电子设备1200可以不向远端用户设备转发数据,而是在用于PDSCH的反馈时间发送第一反馈信息,例如NACK,并且在用于PSFCH的反馈时间发送第二反馈信息,例如NACK。
根据本公开的实施例,如果电子设备1200没有成功接收来自基站设 备的数据,那么电子设备1200可以在用于PDSCH的反馈时间发送第一反馈信息,例如NACK,然后等待基站设备的重传数据,如果电子设备1200成功接收重传数据,则向远端用户设备转发重传数据,反馈单元1240可以根据来自远端用户设备的反馈信息确定第二反馈信息为ACK或者NACK。进一步,电子设备1200可以在用于PSFCH的反馈时间发送第二反馈信息,例如ACK/NACK。
根据本公开的实施例,如果电子设备1200成功接收来自基站设备的数据,那么电子设备1200可以在用于PDSCH的反馈时间发送第一反馈信息,例如ACK。进一步,电子设备1200可以向远端用户设备转发数据,反馈单元1240可以根据来自远端用户设备的反馈信息确定第二反馈信息为ACK或者NACK。进一步,电子设备1200可以在用于PSFCH的反馈时间发送第二反馈信息,例如ACK/NACK。
以上描述了作为网络侧设备的电子设备500和作为中继用户设备的电子设备1200,即电子设备1200可以将来自电子设备500的下行信息转发至远端用户设备。
<4.上行链路传输中网络侧设备的配置示例>
下面仍然参照图5描述在上行链路传输中用于网络侧设备的电子设备500的配置。网络侧设备例如可以为基站设备。
根据本公开的实施例,生成单元510可以生成DCI,该DCI用于上行链路调度。具体地,DCI包括用于远端用户设备向中继用户设备发送数据的第一信道的调度信息和用于中继用户设备向电子设备500转发数据的第二信道的调度信息。
根据本公开的实施例,DCI的尺寸与用于上行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同。
根据本公开的实施例,电子设备500可以通过通信单元520向远端用户设备发送生成的DCI。
如上所述,根据本公开的实施例,电子设备500只需要发送一次DCI就可以携带第一信道和第二信道的调度信息,从而简化了中继传输的过程,减小了数据传输的时延。
根据本公开的实施例,第一信道为PSSCH,第二信道为PUSCH。
根据本公开的实施例,生成单元510生成的DCI可以包括:用于上 行链路调度的DCI格式的字段;以及用于直通链路调度的DCI格式的字段中的不与用于上行链路调度的DCI格式相同的字段。
这里,用于上行链路调度的DCI格式指的是包括基站设备与用户设备之间的上行链路的调度信息的DCI格式,例如DCI格式0,包括但不限于DCI格式0_0、DCI格式0_1、DCI格式0_2。也就是说,用户设备可以根据用于上行链路调度的DCI格式确定PUSCH的发送。
这里,直通链路调度的DCI格式指的是包括用户设备之间的直通链路的调度信息的DCI格式,例如DCI格式3,包括但不限于DCI格式3_0、DCI格式3_1。也就是说,发送侧用户设备可以根据用于直通链路调度的DCI格式确定PSSCH的发送。
根据本公开的实施例,生成单元510生成的DCI包括用于上行链路调度的DCI格式的全部必要的字段和用于直通链路调度的DCI格式的全部必要的字段。而针对用于上行链路调度的DCI格式的全部必要的字段与用于直通链路调度的DCI格式的全部必要的字段中相同的字段,生成的DCI中可以只包括一个。
根据本公开的实施例,由于生成单元510生成的包括两个信道的调度信息的DCI包括用于上行链路调度的DCI格式的全部必要的字段和用于直通链路调度的DCI格式的全部必要的字段,因此新的DCI格式的尺寸大于用于上行链路调度的DCI格式的尺寸和用于直通链路调度的DCI格式的尺寸。
根据本公开的实施例,生成单元510可以将用于上行链路调度的DCI格式补零以使得用于上行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同。这里的用于上行链路调度的DCI格式为DCI格式0,包括但不限于DCI格式0_0、DCI格式0_1、DCI格式0_2。
根据本公开的实施例,生成单元510可以将用于上行链路调度的DCI格式中的一个或多个格式补零以使得用于上行链路调度的DCI格式中的一个或多个格式的尺寸与生成的新的DCI的尺寸相同。例如,生成单元510可以将DCI格式0_1补零以使得DCI格式0_1的尺寸与新的DCI的尺寸相同。再如,生成单元510可以将DCI格式0_1和DCI格式0_0都补零以使得DCI格式0_1和DCI格式0_0的尺寸都与新的DCI的尺寸相同。
根据本公开的实施例,在生成单元510将用于上行链路调度的DCI 格式补零以使得用于上行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同的情况下,编码单元530可以利用用于上下行链路的RNTI对生成的新的DCI进行加扰。根据本公开的实施例,用于上下行链路的RNTI包括但不限于C-RNTI、CS-RNTI和MCS-C-RNTI。
根据本公开的实施例,在生成单元510生成的新的DCI的尺寸与用于上行链路调度的DCI格式中的一个格式的尺寸相同的情况下,用于上下行链路的RNTI进行加扰的DCI格式的尺寸的数目还是三个,从而不会增加远端用户设备的盲检的复杂度。根据本公开的实施例,在生成单元510生成的新的DCI的尺寸与用于上行链路调度的DCI格式中的多个格式的尺寸相同的情况下,用于上下行链路的RNTI进行加扰的DCI格式的尺寸的数目少于三个,从而进一步降低远端用户设备的盲检的复杂度。
根据本公开的实施例,生成单元510在生成用于直通链路调度的DCI格式时,可以将用于直通链路调度的DCI格式补零以使得用于直通链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同。这里的用于直通链路调度的DCI格式为DCI格式3,包括但不限于DCI格式3_0、DCI格式3_1。
根据本公开的实施例,生成单元510可以将用于直通链路调度的DCI格式中的一个或多个格式补零以使得用于直通链路调度的DCI格式中的一个或多个格式的尺寸与生成的新的DCI的尺寸相同。例如,生成单元510可以将DCI格式3_1补零以使得DCI格式3_1的尺寸与新的DCI的尺寸相同。再如,生成单元510可以将DCI格式3_1和DCI格式3_0都补零以使得DCI格式3_1和DCI格式3_0的尺寸都与新的DCI的尺寸相同。
根据本公开的实施例,在生成单元510将用于直通链路调度的DCI格式补零以使得用于直通链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同的情况下,编码单元530可以利用用于直通链路的RNTI对生成的新的DCI进行加扰。根据本公开的实施例,用于直通链路的RNTI包括但不限于SL-RNTI和SL-L-RNTI。
如前文所述,根据本公开的实施例,在生成单元510生成的新的DCI的尺寸与用于直通链路调度的DCI格式中的一个或多个格式的尺寸相同的情况下,用于直通链路的RNTI进行加扰的DCI格式的尺寸的数目不变或更少,从而不会增加或者可以降低远端用户设备的盲检的复杂度。
根据本公开的实施例,编码单元530也可以利用与用于上下行链路的RNTI和用于直通链路的RNTI不同的RNTI对生成的新的DCI进行加扰。也就是说,编码单元530生成一种专用于对这种包括两个信道的调度信息的用于上行调度的DCI进行加扰的RNTI。
如上所述,根据本公开的实施例,生成单元510可以对用于上行链路调度的DCI格式进行补零以使得用于上行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同,或者对用于直通链路调度的DCI格式进行补零以使得用于直通链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。这样一来,可以在不增加远端用户设备的盲检复杂度的同时简化中继过程的操作并降低数据传输的时延。
根据本公开的实施例,生成单元510还可以生成新的DCI以包括用于上行链路调度的DCI格式的字段,以使得用于上行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同。进一步,生成单元510可以利用用于上行链路调度的DCI格式的部分字段来表示第一信道的调度信息,并且利用用于上行链路调度的DCI格式的其它字段来表示第二信道的调度信息。
也就是说,生成单元510可以复用用于上行链路调度的DCI格式中的一些字段来表示用于第二信道的调度信息。这里,可以表示用于第二信道的调度信息中的必要信息,包括但不限于用于第二信道的时域资源和频域资源。例如,生成单元510可以将DCI格式0_1中的字段“优先级指示”、“信道接入-CPext”、“最小适用调度偏移指示”、“辅小区睡眠指示”分别表示DCI格式3_0中的字段“时间空隙”、“初始传输分配的子信道的最低索引”、“SCI格式0-1字段:频域资源分配”和“SCI格式0-1字段:时域资源分配”。当然,上述示例并不是限制性的,生成单元510也可以复用用于上行链路调度的DCI格式中的其它字段。
根据本公开的实施例,生成单元510还可以新添加一个字段来指示上述复用。例如,当新添加的字段为1时,远端用户设备可以确定用于上行链路调度的DCI格式中的一些字段被用来表示用于第二信道的调度信息,不再表示原有的含义。
根据本公开的实施例,由于用于上行链路调度的DCI格式的尺寸与生成的新的DCI的尺寸相同,因此,编码单元530可以利用用于上下行链路的RNTI对生成的新的DCI进行加扰。这样一来,用于上下行链路的RNTI进行加扰的DCI格式的尺寸的数目还是三个,从而不会增加远端用 户设备的盲检的复杂度。
如上所述,根据本公开的实施例,生成单元510可以复用用于上行链路调度的DCI格式中的一些字段来表示第二信道的信息,以使得用于上行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。这样一来,可以在不增加远端用户设备的盲检复杂度的同时简化中继过程的操作并降低数据传输的时延。
图13是示出根据本公开的实施例的利用中继UE执行上行链路传输的信令流程图。在步骤S1301中,基站向远端UE发送DCI,包括用于PSSCH的调度信息和用于PUSCH的调度信息。接下来,在步骤S1302和步骤S1303中,远端UE分别用两个阶段向中继UE发送SCI。在步骤S1304中,远端UE根据用于PSSCH的调度信息利用PSSCH向中继UE发送数据,其中包括从基站接收的用于PUSCH的调度信息。在步骤S1305中,中继UE向远端UE发送关于PSSCH的反馈信息,包括ACK/NACK。在步骤S1306中,中继UE通过接收到的用于PUSCH的调度信息利用PUSCH向基站转发数据。
由此可见,根据本公开的实施例,在利用了中继技术的上行传输过程中,电子设备500只需要发送一次DCI就可以携带第一信道和第二信道的调度信息,从而简化了中继传输的过程,减小了数据传输的时延。进一步,电子设备500可以对用于上行链路调度的DCI格式进行补零以使得用于上行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同,或者对用于直通链路调度的DCI格式进行补零以使得用于直通链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。可选地,电子设备500还可以复用用于上行链路调度的DCI格式中的一些字段来表示第二信道的信息,以使得用于上行链路调度的DCI格式的尺寸与新生成的DCI的尺寸相同。这样一来,可以在不增加远端用户设备的盲检复杂度的同时简化中继过程的操作并降低数据传输的时延。
<5.上行链路传输中用户设备的配置示例>
下面仍然参照图12描述在上行链路传输中用于用户设备的电子设备1200的配置。这里的电子设备1200可以用作远端用户设备。在无线通信系统中,一个用户设备可能将来自基站设备的下行信息转发至其它用户设备,即该用户设备可以作为下行链路传输中的中继用户设备。该用户设备也可能经由其它用户设备向基站设备发送上行数据,即该用户设备可以作为上行链路传输中的远端用户设备。本公开的图12描述了根据本公开的 用户设备的通用配置。也就是说,当用户设备作为下行链路传输中的中继用户设备时,可以按照前文所述的实施例来配置和操作;当用户设备作为上行链路传输中的远端用户设备时,可以按照下文所述的实施例来配置和操作。
根据本公开的实施例,电子设备1200可以通过通信单元1210从基站设备接收DCI,该DCI用于上行链路调度。DCI的尺寸与用于上行链路调度的DCI格式的尺寸或者用于直通链路调度的DCI格式的尺寸相同。
根据本公开的实施例,确定单元1220可以根据DCI确定用于电子设备1200向中继用户设备发送数据的第一信道的调度信息和用于中继用户设备向基站设备转发数据的第二信道的调度信息。
根据本公开的实施例,第一信道为PSSCH,第二信道为PUSCH。
根据本公开的实施例,电子设备1200可以根据第一信道的调度信息向中继用户设备发送数据。例如,电子设备1200可以根据第一信道的调度信息确定向中继用户设备发送数据的时域资源和频域资源。进一步,电子设备1200向中继用户设备发送的数据可以包括第二信道的调度信息,以使得中继用户设备根据第二信道的调度信息向基站设备转发数据。例如,第二信道的调度信息可以包括中继用户设备向基站设备转发数据的时域资源和频域资源。
根据本公开的实施例,电子设备1200接收到的DCI可以包括:用于上行链路调度的DCI格式的字段;以及用于直通链路调度的DCI格式的字段中的不与用于上行链路调度的DCI格式相同的字段。
根据本公开的实施例,确定单元1220可以根据用于直通链路调度的DCI格式的字段中的不与用于上行链路调度的DCI格式相同的字段来确定第一信道的调度信息;以及根据用于上行链路调度的DCI格式的字段确定第二信道的调度信息。
根据本公开的实施例,解码单元1230可以利用用于上下行链路的RNTI、用于直通链路的RNTI、或者与用于上下行链路的RNTI和用于直通链路的RNTI不同的RNTI对DCI进行解扰。
进一步,根据本公开的实施例,在解码单元1230利用用于上下行链路的RNTI对DCI成功解扰的情况下,确定单元1220可以进一步确定没有进行补零的DCI为包括两个信道的调度信息的DCI,而进行了补零的DCI为用于上行链路调度的DCI。根据本公开的实施例,在解码单元1230 利用用于直通链路的RNTI对DCI成功解扰的情况下,确定单元1220可以进一步确定没有进行补零的DCI为包括两个信道的调度信息的DCI,而进行了补零的DCI为用于直通链路调度的DCI。在解码单元1230利用与用于上下行链路的RNTI和用于直通链路的RNTI不同的RNTI对DCI成功解扰的情况下,确定单元1220可以确定该DCI为包括两个信道的调度信息的DCI。
如上所述,根据本公开的实施例,用于上行链路调度的DCI格式的尺寸与新的DCI的尺寸相同,或者用于直通链路调度的DCI格式的尺寸与新的DCI的尺寸相同,从而电子设备1200在进行盲检时不会增加复杂度。
根据本公开的实施例,电子设备1200接收到的DCI可以包括用于上行链路调度的DCI格式的字段。
根据本公开的实施例,确定单元1220可以根据用于上行链路调度的DCI格式的部分字段确定第一信道的调度信息;以及根据用于上行链路调度的DCI格式的其它字段确定第二信道的调度信息。
根据本公开的实施例,解码单元1230可以利用用于上下行链路的RNTI和用于直通链路的RNTI对DCI进行解扰。进一步,在解码单元1230利用用于上下行链路的RNTI对DCI成功解扰的情况下,确定单元1220可以根据DCI中的一个新增加的字段来确定该DCI是新的包括两个信道的调度信息的DCI还是用于上行链路调度的DCI。
例如,当DCI中一个新增加的字段为1时,确定单元1220可以确定用于上行链路调度的DCI格式中的一些字段被用来表示用于第二信道的调度信息,不再表示原有的含义。作为一个示例,确定单元1220可以将DCI格式0_1中的字段“优先级指示”、“信道接入-CPext”、“最小适用调度偏移指示”、“辅小区睡眠指示”分别理解为字段“时间空隙”、“初始传输分配的子信道的最低索引”、“SCI格式0-1字段:频域资源分配”和“SCI格式0-1字段:时域资源分配”的含义。也就是说,确定单元1220可以根据上述字段来确定第二信道的调度信息。当然,上述示例并不是限制性的,用于上行链路调度的DCI中的其他字段也可能被复用。
如上所述,根据本公开的实施例,用于上行链路调度的DCI格式的尺寸与新的DCI的尺寸相同,从而电子设备1200在进行盲检时不会增加复杂度。
