示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。
图1示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
应理解,在本申请实施例中,NR也可以独立部署,5G网络环境中为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC_INACTIVE(非激活)状态。这种状态有别于RRC_IDLE(空闲)和RRC_CONNECTED(连接)状态。
在RRC_IDLE状态下:移动性为基于终端设备的小区选择重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。基站侧不存在终端设备接入层(Access Stratum,AS)上下文,也不存在RRC连接。
在RRC_CONNECTED状态下:存在RRC连接,基站和终端设备存在终端设备AS上下文。网络设备知道终端设备的位置是具体小区级别的。移动性是网络设备控制的移动性。终端设备和基站之间可以传输单播数据。
RRC_INACTIVE:移动性为基于终端设备的小区选择重选,存在CN-NR之间的连接,终端设备AS上下文存在某个基站上,寻呼由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络设备知道终端设备的位置是基于RAN的寻呼区域级别的。
需要说明的是,在本申请实施例中,非激活态也可以称之为去激活态,本申请对此并不限定。
NR系统中支持的最大信道带宽可以到400MHZ(宽带载波,wideband carrier),如果UE一直保持工作在宽带载波上,则UE的功率消耗是很大的。根据UE实际的吞吐量来调整UE的射频(Radio Frequency,RF)带宽可以优化UE的功率消耗,这就是引入带宽部分(Bandwidth Part,BWP)的动 机。
处于RRC_IDLE状态或者RRC_INACTIVE状态的UE驻留在初始(initial)BWP上,这个BWP对于RRC_IDLE状态或者RRC_INACTIVE状态的UE是可见的,UE可以在这个BWP里面可以获取主信息块(Master Information Block,MIB),剩余系统信息(Remaining System Information,RMSI),其他系统信息(Other System Information,OSI)以及寻呼(paging)等信息。
NR系统仅支持单播传输,并且RRC连接状态的终端设备的单播传输是需要进行混合自动请求重传-肯定应答(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)信息反馈的。
在NR系统中的一些业务考虑引入PTM传输,例如车辆到其他设备(Vehicle to Everything,V2X)工业网互联网业务等。相应地,需要引入针对PTM传输的HARQ-ACK反馈机制。
图2为本申请实施例提供的一种传输反馈信息的方法200的示意性流程图。该方法200可以由图1所示的通信系统中的终端设备执行,如图2所示,该方法200可以包括如下至少部分内容:
S210,终端设备接收网络设备发送的物理下行数据信道PDSCH,所述PDSCH用于承载所述网络设备向多个终端设备发送的一点到多点PTM传输,所述终端设备为所述多个终端设备中的一个;
S220,所述终端设备对所述PTM传输进行反馈。
可选地,在本申请实施例中,所述PTM传输可以指一点到多点的任一种传输方式,例如组播传输,广播传输或多播传输等。
在本申请实施例中,网络设备可以通过物理下行共享信道(Physical Downlink Shared Channel,PDSCH)进行PTM传输。即PTM传输可以承载在PDSCH中。在其他实施例中,所述PTM传输可以承载在其他数据信道中,本申请实施例对此不作限定。
应理解,本申请实施例并不具体限定网络设备进行PTM传输的终端设备的个数。
作为一个示例,如图3所示,所述多个终端设备可以包括UE#0,UE#1,UE#2,UE#3,网络设备例如gNB可以向UE#0,UE#1,UE#2,UE#3发送PTM传输#0,简称PTM#0。
在一些实施例中,终端设备还可以接收网络设备的单播传输,所述PTM传输和所述单播传输可以在正交的上行资源进行HARQ-ACK反馈,或者也可以在同一上行资源上进行HARQ-ACK反馈。其中,用于PTM传输和/或单播传输反馈的上行资源可以是网络设备指示或配置的。
在一些实施例中,PTM传输和/或单播传输的HARQ-ACK信息可以通过物理上行控制信道(Physical Uplink Control channel,PUCCH)承载。
例如,可以通过一个PUCCH承载一个或多个PTM传输的HARQ-ACK信息。
又例如,可以通过一个PUCCH同时承载PTM传输和单播传输的HARQ-ACK信息。
在介绍根据本申请实施例的PTM传输的反馈机制之前,首先根据本申请实施例的PTM传输的调度方式做一说明。
在一些实施例中,所述终端设备通过接收网络设备的信令指示,确定一个PTM传输所对应的标识,例如组播广播业务无线网络临时标识符(Multicast Broadcast Service Radio Network Temporary Identity,MBS-RNTI)。进一步接收由所述MBS-RNTI加扰的物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度的承载PTM传输的PDSCH,然后根据接收结果反馈相应的HARQ-ACK信息。
在一些实施例中,终端设备可以在当前激活的BWP上接收MBS-RNTI加扰的PDCCH,所述PDCCH用于调度终端设备在同一BWP上接收承载PTM传输的PDSCH。
在这种情况下,所述PDCCH可以在终端设备专属搜索空间(UE Search Space,USS)中发送,所述PDSCH可以在公共搜索空间(Common Search Space,CSS)或USS中发送。
在另一些实施例中,终端可以在当前激活的BWP上接收MBS-RNTI加扰的PDCCH,然后根据PDCCH指示在另外一个BWP上接收承载PTM传输的PDSCH。
此情况下,在接收所述PDSCH之后,终端设备可以切换回接收所述PDCCH的BWP。或者,若终端设备当前激活的BWP上没有调度PTM传输的PDCCH搜索空间,终端设备可以根据半静态调度配置在当前激活的BWP上接收PTM传输,或者在另一个BWP根据半静态调度接收PTM传输。
可选地,在USS中发送的调度PTM传输的PDCCH中携带的比特数和PDCCH格式1-1中的比特数相同,在CSS中发送的调度PTM传输的PDCCH中携带的比特数和PDCCH格式1-0中的比特数相同。
在本申请实施例中,所述终端设备可以根据网络设备的指示或配置或在正交的不同上行资源或同一上行资源上通过PUCCH反馈PTM传输的HARQ-ACK信息和单播传输的HARQ-ACK信息,在使用不同的上行资源的情况下,终端设备采用相应的方式确定PUCCH的发送功率,下文中进行详细说明。
在本申请实施例中,网络设备可以给终端设备配置PUCCH资源。可选地,网络设备配置的PUCCH资源例如可以包括用于所述多个终端设备进行PTM传输反馈的公共PUCCH资源,或者也可以包括用于所述终端设备进行PTM传输反馈的专用PUCCH资源,或者网络设备可以不给终端设备配置PTM传输的专用资源,只配置通用PUCCH资源。终端设备可以根据该PUCCH资源的类型,采用相应的反馈方式进行PTM传输的反馈。
反馈方式1
所述终端设备上配置有用于所述多个终端设备进行PTM传输反馈的公共PUCCH资源。可选地,所述公共PUCCH资源可以与所述多个终端设备上的其他PUCCH资源正交。所述公共PUCCH资源可以为所述PTM传输专用的PUCCH资源,所述公共PUCCH资源为调度所述PTM传输的PDCCH的MBS-RNTI对应的公共PUCCH资源。
可选地,所述其他PUCCH资源可以用于传输上行控制信息(Uplink Control Information,UCI)或者,单播传输的HARQ-ACK信息等。
此情况下,所述终端设备根据所述PDSCH的解码结果,在所述公共PUCCH资源上进行反馈。作为示例,反馈否定确认(Negative Acknowledgement,NACK)或者不对所述PTM传输进行反馈,即发送任何反馈信息。例如,若所述PDSCH未成功解码,所述终端设备在所述公共PUCCH资源上反馈NACK。又例如,若所述PDSCH成功解码,所述终端设备不对所述PTM传输进行反馈。
在该反馈方式1中由于终端设备是在公共PUCCH资源上进行反馈的,任一终端设备反馈NACK,网络设备都可以认为此次PTM传输失败,因此,终端设备只需在解码失败的情况下进行反馈,在解码成功的情况下,不进行反馈,从而能够避免多个终端设备同时在一个PUCCH资源进行反馈,增加网络侧的功率控制复杂度。
结合图4,以图3所示的PTM传输举例说明,所述UE#0,UE#1,UE#2,UE#3均可以在PTM#0对应的专用PUCCH资源上发送HARQ-ACK信息。PTM#0对应的专用PUCCH资源与UE#0,UE#1,UE#2,UE#3上的其他PUCCH资源正交。
例如若UE1未成功解码未能成功解码承载该PTM#0的PDSCH,则反馈NACK,否则不反馈。
在该反馈方式1中,若所述公共PUCCH资源和所述终端设备的其他PUCCH资源在时域上存在重叠,并且所述终端设备没有能力同时在所述公共PUCCH资源和所述其他PUCCH资源上发送PUCCH。此情况下,所述终端设备不对所述PTM传输进行反馈,优先在所述其他PUCCH资源发送PUCCH。
在一些实施例中,若所述PTM传输包括多个传输块TB,所述公共PUCCH资源包括多个TB对应一个PUCCH资源,此情况下,所述终端设备根据所述多个TB的解码结果在所述一个PUCCH资源上进行反馈。例如,若所述多个TB均解码成功,所述终端设备不在所述一个PUCCH资源上反馈;或者若所述多个TB中有一个TB未解码成功,所述终端设备则在所述一个PUCCH资源上反馈NACK。
在另一些实施例中,若所述PTM传输包括多个传输块TB,所述公共PUCCH资源包括所述多个TB中的每个TB分别对应的PUCCH资源,则所述终端设备根据所述多个TB中的每个TB的解码结果在对应的PUCCH资源上进行反馈。例如,若所述多个TB中的第一TB解码成功,所述终端设备不在所述第一TB对应的PUCCH资源上反馈;或者若所述第一TB未解码成功,所述终端设备在所述第一TB对应的PUCCH资源上反馈NACK。
反馈方式2
所述终端设备上配置有用于所述多个终端设备中的每个终端设备进行PTM传输反馈的专用PUCCH资源。即该PTM传输对应一个PUCCH资源集合,包括用于所述多个终端设备的每个终端设备进行PTM传输反馈的专用PUCCH资源,或者说,该PUCCH资源集合为调度该PTM传输的PDCCH的MBS-RNTI对应的PUCCH资源集合。
可选地,所述PUCCH资源集合可以与所述多个终端设备上的其他PUCCH资源正交。
此情况下,所述终端设备根据所述PDSCH的解码结果,在所述终端设备的专用PUCCH资源上进行反馈,例如反馈NACK或反馈确认ACK。
作为一个示例,若所述PDSCH未成功解码,所述终端设备在所述终端设备的专用PUCCH资源上反馈NACK;或若所述PDSCH成功解码,所述终端设备在所述终端设备的专用PUCCH资源上反馈ACK。
结合图5,以图3所示的PTM传输举例说明,所述UE#0,UE#1,UE#2,UE#3分别对应各自的用于PTM#0反馈的专用PUCCH资源,UE#0,UE#1,UE#2,UE#3可以在各自的专用PUCCH资源上发送HARQ-ACK信息,UE#0,UE#1,UE#2,UE#3各自分别对应的专用PUCCH资源与UE#0,UE#1,UE#2,UE#3上的其他PUCCH资源正交。
例如若UE1未成功解码未能成功解码承载该PTM#0的PDSCH,则在UE1专用的PUCCH资源上反馈NACK,否则,在UE1专用的PUCCH资源上反馈ACK。
在上述反馈方式2中,若所述终端设备的专用PUCCH资源和所述终端设备的其他PUCCH资源在时域上存在重叠,并且所述终端设备没有能力同时在所述专用PUCCH资源和所述其他PUCCH资源上发送PUCCH。此情况下,所述终端设备可以根据所述专用PUCCH资源上传输的第一PUCCH的大小,所述其他PUCCH资源中传输的第二PUCCH的大小,所述第二PUCCH的优先级等信息,进行PTM传输的反馈。
例如,若所述第二PUCCH的优先级高于第一优先级阈值(或者,调度该第二PUCCH的PDCCH中的优先级域指示为高优先级),即第二PUCCH为高优先级业务,此情况下,所述终端设备可以不对所述PTM传输进行反馈,在所述其他PUCCH资源上发送所述第二PUCCH。
又例如,若所述第二PUCCH的优先级低于第一优先级阈值(或者,调度该第二PUCCH的PDCCH中的优先级域指示为低优先级),即第二PUCCH为低优先级业务,此情况下,所述终端设备可以在所述专用PUCCH资源上发送所述第一PUCCH,不在所述其他PUCCH资源上发送所述第二PUCCH。
可选地,若所述PTM传输包括多个传输块TB,所述终端设备也可以采用反馈方式1所述的方式进行TB粒度的HARQ-ACK信息的反馈,为了简洁,这里不再赘述。
反馈方式3
所述终端设备上未配置用于PTM传输反馈的PUCCH资源,即既未配置反馈方式1中的公共PUCCH资源,又未配置反馈方式2中的专用PUCCH资源。
此情况下,所述终端设备可以使用通用PUCCH资源进行PTM传输的反馈。
作为一个实施例,所述终端设备可以根据所述PDSCH的解码结果,确定反馈NACK还是ACK。例如,若所述PDSCH未成功解码,所述终端设备在所述通用PUCCH资源上反馈NACK。又例如,若所述PDSCH成功解码,所述终端设备在所述通用PUCCH资源上反馈ACK。
作为另一实施例,所述终端设备也可以在特定条件下使用所述通用PUCCH资源进行PTM传输的反馈。
例如,若调度PTM传输的PDCCH是在所述终端设备的USS中发送的,此情况下,所述终端设备在所述通用PUCCH资源上对所述PTM传输进行反馈。
又例如,若调度PTM传输的PDCCH是在所述多个终端设备的CSS中发送的,此情况下,所述终端设备不使用所述通用PUCCH资源对所述PTM传输进行反馈。
进一步地,基于上述反馈方式,所述终端设备还可以进一步确定发送承载反馈信息的第一PUCCH所使用的发送功率。
具体地,所述终端设备根据发送第一PUCCH所使用的所述第一PUCCH资源的类型,确定发送所述第一PUCCH所使用的发送功率,其中,所述第一PUCCH用于承载所述PTM传输的反馈信息。
以下,分别结合前述的三种反馈方式,说明对应的发送功率的确定方式。
对于反馈方式1
在上述反馈方式1中,由于终端设备通过专用于PTM传输的公共PUCCH资源反馈PTM传输的HARQ-ACK信息,如果存在多个终端设备都接收到该PTM传输,则可能出现所有终端设备在相同的PUCCH资源上发送PUCCH进行HARQ-ACK反馈的情况。
也就是说,在所述公共PUCCH资源上的发送功率和终端设备在其它PUCCH资源上的发送功率相比,网络侧对PUCCH的目标接收功率可能不同。此外,由于在所述公共PUCCH资源上,可能存在多个终端设备发送的PUCCH,网络侧无法识别单个终端设备发送的PUCCH。此情况下,在本申请实施例中,网络设备可以不针对单个终端设备在该公共PUCCH资源上发送的PUCCH进行闭环功率控制,例如,可以对单个终端设备在该PUCCH资源上发送的PUCCH进行开环功率控制,或者也可以对接收PTM传输的多个终端整体进行闭环功率控制。以下,结合方式1-1和方式1-2具体说明。
方式1-1:所述终端设备只根据开环功率控制参数,确定所述第一PUCCH的发送功率。即网络设备只对终端设备进行开环功率控制。
可选地,所述开环功率控制参数包括如下中的至少一项:
PUCCH的目标接收功率;
PUCCH的传输带宽;
与所述PUCCH格式相关的调整值;
与所述PUCCH的码率相关的补偿因子。
可选地,在一些实施例中,所述PUCCH的目标接收功率可以是所述网络设备配置的用于所述公共PUCCH资源上的发送的PUCCH的目标接收功率,即网络设备可以配置专用于所述公共PUCCH 资源的PUCCH目标接收功率。
可选地,在另一些实施例中,所述PUCCH的目标接收功率根据网络设备在PUCCH空间相关信息(PUCCH-spatialrelationinfo)中指示的内容确定。
具体的,对于公共PUCCH资源,网络设备可以配置多个PUCCH空间相关信息(PUCCH-spatialrelationinfo),例如,在RRC信令中配置,然后再通过媒体接入控制(Media Access Control,MAC)层信令指示当前所用的PUCCH-spatialrelationinfo。其中,每个PUCCH-spatialrelationinfo中包含一个用于确定PUCCH的发送波束的参考信号,例如,可以是SRS或信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)或同步信号块(Synchronization Signal Block,SSB)。
在该实施例中,所述PUCCH的目标接收功率可以根据所述MAC CE指示的当前激活的PUCCH-spatialrelationinfo中所指示的内容确定。
示例1:在所述公共PUCCH资源上发送的PUCCH的发送功率可以根据如下公式(1)确定:
Figure PCTCN2020107987-appb-000001

对于反馈方式2
在上述反馈方式2中,由于终端设备通过专用于该终端设备的PTM传输的PUCCH资源反馈PTM传输的HARQ-ACK信息,如果存在多个终端设备接收该PTM传输,若每个终端设备均需要反馈PTM传输的HARQ-ACK信息,在一些实现方式中,该多个终端设备所用的PUCCH资源可能是通过码分方式复用实现。
在一些实现方式中,每个终端设备的PUCCH发送功率的设计可以与无线链路的路径损耗成正比例关系,这样,有利于保证网络设备接收到的每个终端设备的PUCCH的功率接近。因此,在终端设备的专用PUCCH资源上的发送功率和该终端设备在其它PUCCH资源上的发送功率相比,网络设备对PUCCH的目标接收功率可能不同,而且,网络设备对专用PUCCH资源上的功率调整需求也可能不同于终端设备的其它PUCCH资源,因此,网络设备可以通过专门用于PTM传输的功率控制命令调整终端设备在专用PUCCH资源上的发送功率。即网络设备可以对PTM传输反馈的发送功率进行独立控制。以下,结合方式2-1具体说明。
方式2-1
若所述第一PUCCH资源为所述终端设备的专用PUCCH资源,所述终端设备根据开环功率控制参数和第二闭环功率调整因子,确定所述第一PUCCH的发送功率。
在一些实施例中,所述第二闭环功率调整因子是所述终端设备专用的。即网络设备可以对所述多个终端设备中的每个终端设备发送PUCCH的发送功率单独进行闭环功率控制。
在另一些实施例中,所述第二闭环功率调整因子是所述多个终端设备共用的。即网络设备可以对所述多个终端设备发送PUCCH的发送功率整体进行闭环功率控制。
可选地,在一些实施例中,所述第二闭环功率调整因子通过第二PDCCH指示。
可选地,所述第二PDCCH在所述多个终端设备的CSS发送和/或在所述终端设备的USS发送。
在一些实施例中,所述第二PDCCH为以下中的至少一种:
在所述终端设备的USS上发送的用于调度所述PTM传输的PDCCH;
在所述多个终端设备的CSS上发送的用于调度所述PTM传输的PDCCH;
在所述多个终端设备的CSS上发送的所述PTM传输对应的多播业务无线网络临时标识MBS-RNTI加扰的功率控制指示PDCCH。
可选地,在一些实施例中,所述功率控制指示PDCCH包括多个功率控制命令,分别对应所述多个终端设备,每个功率控制命令用于配置对应的终端设备的闭环功率调整因子。
示例5:在专用PUCCH资源上发送的PUCCH的发送功率可以根据如下公式(5)确定:

其中,公式(5)中的闭环功控调整状态g b,f,c(i)的确定方式参考公式(3)的g b,f,c(i)的确定方式。
所述公式(5)中的其他参数的确定方式参考公式(1)的相关参数的确定方式,为了简洁,这里不再赘述。

其中,公式(6)中的闭环功控调整状态g b,f,c(i)的确定方式参考公式(3)的g b,f,c(i)的确定方式。
所述公式(6)中的其他参数的确定方式参考公式(2)的相关参数的确定方式,为了简洁,这里不再赘述。
在该方式2-1中,所述第二闭环功率调整因子可以包括所述闭环功率调整状态g b,f,c(i)。
对于反馈方式3
在上述反馈方式3中,由于终端设备通过通用PUCCH资源发送所有下行传输的HARQ-ACK反馈信息,所以,终端设备可以不必对该PTM传输进行单独的功率控制,而采用通用PUCCH的发送功率的确定方式确定承载PTM传输的反馈信息的PUCCH的发送功率。
示例7:在通用PUCCH资源上发送的PUCCH的发送功率可以根据如下公式(7)确定:
Figure PCTCN2020107987-appb-000011
其中,公式(7)中的参数的确定方式参考相关技术中关于通用PUCCH资源上的PUCCH的发送功率的参数的确定方式,为了简洁,这里不再赘述。
因此,在本申请实施例中的PTM传输的反馈方法,对于不同的PUCCH资源配置方式,终端设备可以采用相应的反馈方式进行HARQ-ACK信息的反馈,并且能够根据具体的反馈方式确定合理有效的发送PUCCH的发送功率,从而能够提高PTM传输的可靠性。
