具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本公开实施例中的描述, 上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端设备。网络设备120与终端设备14之间通过某种空口技术互相通信,例如Uu接口。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long Term Evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
在5G NR系统中,上述网络设备120可以包括N个传输接收点(Transmission Reception Point,TRP)。
图2示出了本公开一个示例性实施例提供的基于多个传输接收点或多个天线面板(multi-TRP/panel)的数据传输的示意图。
终端设备210处于服务小区(serving cell)之中,也处于邻小区(neighboring  cell)之中。
其中,每个小区可以由不止一个传输接收点来覆盖。如图2所示,服务小区由传输接收点1和传输接收点2联合覆盖,从而增大了服务小区的覆盖半径。邻小区由传输接收点3覆盖。
每个传输接收点可以设置有一个以上的天线面板(panel)。不同的天线面板的朝向可不同,从而可以收发不同传输方向的波束,从而实现多空间分集。在本实施例中,传输接收点1和传输接收点2分别包括一个天线面板:传输接收点1包括天线面板1,传输接收点2包括天线面板2;传输接收点3包括两个天线面板:天线面板3和天线面板4。
网络设备可以使用多个天线面板(该多个天线面板可以来自同一个传输接收点或不同的传输接收点)同时向终端设备210发送PDCCH。这种情况下,不同天线面板的发送方向不一样,所以终端设备210也需要使用不同的天线面板来接收PDCCH,那么网络设备需要指示不同的传输配置指示(Transmission Configuration Indication,TCI)状态给终端设备,每个TCI状态对应终端设备的每个天线面板上的一个接收波束方向。通过上述基于波束(beam)的发送和接收方式,可以保证覆盖范围。
具体地,网络设备可以通过信令指示type D的TCI状态,从而告知终端设备210接收时需要使用的接收波束。其中,每个TCI状态对应一个参考信号(Reference Signal,RS)标识,该RS既可以是非零功率信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),也可以是同步信号块(Synchronization Signal Block,SSB),还可以是探测参考信号(Sounding Reference Signal,SRS)。
当信令给出type D的TCI状态信息,指示终端设备210接收该PDCCH时,终端设备210使用接收该TCI状态信息中包含的RS标识对应的RS时接收功率最大时使用的Rx beam,接收该PDCCH,如表一所示。
表一
TCI状态信息 RS index
TCI#0 SSB index#1
TCI#1 SSB index#2
TCI#2 CSI-RS index#5
TCI#3 CSI-RS index#6
…… ……
示例性的,网络设备若告知终端设备210使用TCI#0,则是告诉终端设备210使用接收SSB index#1时接收功率最大时的Rx beam来接收PDCCH。
网络设备还可以通过指示空间关系信息(Spatial Relation info),来指示波束信息。每个空间关系信息对应一个RS标识,该RS既可以是非零功率CSI-RS,也可以是SSB,还可以是SRS。
图3示出了本申请一个示例性实施例提供的数据传输方法的示意图,可以应用于如图1所示的终端设备和网络设备中。该方法包括:
步骤310,网络设备向终端设备发送至少两个PDCCH。
相应地,终端设备接收至少两个PDCCH。
PDCCH是网络设备发送至终端设备的下行控制信道。PDCCH承载调度以及其他控制信息,具体包含传输格式、资源分配、上行调度许可、功率控制以及重传信息中的至少一种。
步骤320,在终端设备和网络设备之间,传输至少两个数据信道。
其中,至少两个数据信道由至少两个PDCCH调度传输。至少两个PDCCH和至少两个数据信道采用联合重复传输的方式,即:至少两个PDCCH传输同样的内容,或,至少两个数据信道传输同样的内容,或,至少两个PDCCH传输同样的内容且至少两个数据信道传输同样的内容。
一个PDCCH可以调度一个数据信道,一个数据信道可以是唯一的一个数据信道;也可以是包括采用微时隙(mini-slot)或时隙(slot)多次重复传输的同一个数据信道的集合。
可选地,至少两个PDCCH传输同样的内容指的是:至少两个PDCCH承载同样的下行控制信息(Downlink Control Information,DCI)信令。通过该DCI信令,可以调度终端设备与一个或多个天线面板之间的数据传输,而多个天线面板可以属于同一传输接收点或不同传输接收点或不同小区。
数据信道可以是网络设备发送至终端设备的下行数据信道,也可以是终端设备发送至网络设备的上行数据信道,本公开对此不进行限制。若至少两个数据信道是由网络设备发送至终端设备的下行数据信道,则网络设备发送至少两个数据信道,终端设备接收至少两个数据信道;若至少两个数据信道是由终端 设备发送至网络设备,则终端设备发送至少两个数据信道,网络设备接收至少两个数据信道。
可选地,至少两个数据信道传输同样的内容指的是:每个数据信道传输同样的数据。若至少两个数据信道是上行数据信道,则至少两个数据信道传输同样的上行数据;若至少两个数据信道是下行数据信道,则至少两个数据信道传输同样的下行数据。
需要说明的是,本公开不对上述步骤310和步骤320的实施顺序进行限定。步骤310可以在步骤320之前实施,步骤310中的部分步骤也可以在步骤320中的部分步骤之后实施。如:步骤310中的“发送至少两个PDCCH”实施完成之后,再实施步骤320中的“传输至少两个数据信道”;或在发送完步骤310中的一个PDDCH后,先实施步骤320中相应的数据信道的传输,再继续实施步骤310,进行PDCCH的传输。
综上所述,本实施例提供的方法,在终端设备和网络设备之间,可以传输至少两个PDCCH和传输至少两个数据信道,通过至少两个PDCCH传输同样的内容,或,至少两个数据信道传输同样的内容,或,至少两个PDCCH传输同样的内容且至少两个数据信道传输同样的内容,以实现控制信道和数据信道联合重复传输,提高了通信的鲁棒性。
在基于图3的可选实施例中,网络设备和终端设备之间可以基于多个传输接收点或多个天线面板(multi-TRP/panel),通过多波束进行控制信道和数据信道的联合重复传输。
下面,对基于multi-TRP/panel,通过多波束传输至少两个PDCCH进行解释说明。
在一个可选的实施例中,网络设备使用不同的发送波束,发送至少两个PDCCH。相应地,终端设备使用不同的接收波束,接收至少两个PDCCH。
在一种可能的设计中,至少两个PDCCH来自不同的小区。在另一种可能的设计中,至少两个PDCCH来自同一小区的不同传输接收点。在另一种可能的设计中,至少两个PDCCH来自同一传输接收点的不同天线面板。
对于网络设备来说,在一种可能的设计中,网络设备通过不同的小区发送至少两个PDCCH。在另一种可能的设计中,网络设备通过同一小区的不同传输接收点发送至少两个PDCCH。在另一种可能的设计中,网络设备通过同一传输 接收点的不同天线面板发送至少两个PDCCH。
至少两个PDCCH由网络设备通过不同的天线面板发送。不同的天线面板可属于不同小区,也可以属于同一小区的不同传输接收点,也可以属于同一传输接收点的不同天线面板。由于不同的天线面板的发送方向不一样,所以终端设备也需要使用不同的天线面板(对应不同的接收波束)来接收至少两个PDCCH。
示例性的,至少两个PDCCH包括:第一PDCCH和第二PDCCH。其中,第一PDCCH来自服务小区,第二PDCCH来自邻小区。网络设备使用发送波束a,发送波束b分别发送上述两个PDCCH,终端设备使用相应的接收波束c,接收波束d分别接收上述两个PDCCH。
可选地,终端设备可以通过TCI状态信息,也可以通过空间关系信息(spatial relation info)来确定接收波束。终端设备通过TCI状态信息(或空间关系信息)来确定接收波束的过程可以包括:网络设备通过无线资源控制(Radio Resource Control,RRC)信令通知终端设备至少一个TCI状态信息(或空间关系信息),包括TCI状态信息(或空间关系信息)的标识及其对应的RS类型和RS标识;若RRC信令告知了多个TCI状态信息(或空间关系信息),则网络设备再使用媒体接入控制(Medium Access Control,MAC)信令激活上述多个TCI状态信息(或空间关系信息)中的一个TCI状态信息(或空间关系信息),该被激活的TCI状态信息(或空间关系信息)即为网络设备给该终端设备的PDCCH的传输状态配置(或空间关系信息),即告知终端设备接收PDCCH时使用的接收波束应当与接收该TCI状态信息对应的RS时接收功率最强时所使用的接收波束相同,或,与发送该空间关系信息对应的RS所使用的发送波束对应的接收波束相同。之后,终端便可以使用上述确定的多个不同的接收波束,接收至少两个PDCCH。
在一个可选的实施例中,至少两个PDCCH传输不同的内容。
此种情况下,为了实现控制信道和数据信道联合重复传输,至少两个数据信道传输不同的内容。
可选地,至少两个PDCCH传输不同的内容,可以包括如下几种情况中的任意一种:
情况1:至少两个PDCCH来自不同的小区,至少两个PDCCH分别调度终端设备与至少两个PDCCH对应的小区之间的数据传输;
情况2:至少两个PDCCH来自同一小区的不同的传输接收点,至少两个 PDCCH分别调度终端设备与至少两个PDCCH对应的传输接收点之间的数据传输;
情况3:至少两个PDCCH来自同一传输接收点的不同的天线面板,至少两个PDCCH分别调度终端设备与至少两个PDCCH对应的天线面板之间的数据传输。
下面,对基于multi-TRP/panel,通过多波束传输至少两个数据信道进行解释说明。
数据信道可以是物理下行共享信道(Physical Downlink Shared CHannel,PDSCH),也可以是物理上行共享信道(Physical Uplink Shared CHannel,PUSCH)。

相应地,终端设备根据至少两个PDCCH指示的接收波束信息,接收至少两个PDSCH。
至少两个PDSCH由至少两个PDCCH调度传输。具体地,一个PDCCH可以调度一个PDSCH;也可以调度采用微时隙(mini-slot)或时隙(slot)多次重复传输的一个PDSCH的集合。由于至少两个PDCCH携带有接收波束信息,终端设备可以根据接收到的至少两个PDCCH指示的接收波束信息,接收至少两个PDSCH。
在一种可能的设计中,至少两个PDSCH来自不同的小区。在另一种可能的设计中,至少两个PDSCH来自同一小区的不同传输接收点。在另一种可能的设计中,至少两个PDSCH来自同一传输接收点的不同天线面板。

至少两个PDSCH由网络设备通过不同的天线面板发送。不同的天线面板可 属于不同小区,也可以属于同一小区的不同传输接收点,也可以属于同一传输接收点的不同天线面板。由于不同的天线面板的发送方向不一样,所以终端设备也需要使用不同的天线面板(对应不同的接收波束)来接收至少两个PDSCH。
示例性的,至少两个PDSCH包括:第一PDSCH和第二PDSCH。其中,第一PDSCH来自服务小区,第二PDSCH来自邻小区。网络设备使用发送波束a,发送波束b分别发送上述两个PDSCH,终端设备使用相应的接收波束c,接收波束d分别接收上述两个PDSCH。
可选地,网络设备使用不同的发送波束,发送至少两个PDSCH。相应地,终端设备根据至少两个PDCCH指示的接收波束信息,确定不同的接收波束;使用不同的接收波束,接收至少两个PDSCH。
接收波束信息可以是TCI状态信息(或空间关系信息)。终端设备通过TCI状态信息(或空间关系信息)来确定接收波束的过程可以包括:网络设备通过RRC信令通知终端设备至少一个TCI状态信息(或空间关系信息),包括TCI状态信息(或空间关系信息)的标识及其对应的RS类型和RS标识;若RRC信令告知了多个TCI状态信息(或空间关系信息),则网络设备再使用MAC信令激活上述多个TCI状态信息(或空间关系信息)中的M个TCI状态信息(或空间关系信息),再用DCI信令指示M个中的一个TCI状态信息(或空间关系信息),该被指示的TCI状态信息(或空间关系信息)即为网络设备给该终端设备的PDSCH的传输状态配置(或空间关系信息),即告知终端设备接收PDSCH时使用的接收波束应当与接收该TCI状态信息对应的RS所使用的接收波束相同,或,与发送该空间关系信息对应的RS所使用的发送波束对应的接收波束相同。之后,终端便可以使用上述确定的多个不同的接收波束,接收至少两个PDSCH。

PUSCH是PDSCH的上行对应信道。每个终端设备的上行分量载波最多有一个PUSCH。
在一个可选的实施例中,终端设备根据至少两个PDCCH指示的发送波束信息,发送至少两个PUSCH。
相应地,网络设备接收至少两个PUSCH;其中,至少两个PUSCH是终端设备根据至少两个PDCCH指示的发送波束信息发送的。
至少两个PUSCH由至少两个PDCCH调度传输。具体地,一个PDCCH可 以调度一个PUSCH,也可以调度采用微时隙(mini-slot)或时隙(slot)多次重复传输的一个PUSCH的集合。由于至少两个PDCCH携带有发送波束信息,终端设备可以根据接收到的至少两个PDCCH指示的发送波束信息,发送至少两个PUSCH。
在一种可能的设计中,至少两个PUSCH发送至不同的小区。在另一种可能的设计中,至少两个PUSCH发送至同一小区的不同传输接收点。在另一种可能的设计中,至少两个PUSCH发送至同一传输接收点的不同天线面板。
对于网络设备来说,在一种可能的设计中,网络设备通过不同的小区接收至少两个PUSCH。在另一种可能的设计中,网络设备通过同一小区的不同传输接收点接收至少两个PUSCH。在另一种可能的设计中,网络设备通过同一传输接收点的不同天线面板接收至少两个PUSCH。
至少两个PUSCH由终端设备根据至少两个PDCCH指示的发送波束信息,通过不同的天线面板发送。网络设备通过不同的天线面板接收,不同的天线面板可属于不同小区,也可以属于同一小区的不同传输接收点,也可以属于同一传输接收点的不同天线面板。由于终端设备不同的天线面板的发送方向不一样,所以网络设备也需要使用不同的天线面板(对应不同的接收波束)来接收至少两个PUSCH。
示例性的,至少两个PUSCH包括:第一PUSCH和第二PUSCH。其中,第一PUSCH来自终端设备的天线面板1,第二PUSCH来自终端设备的天线面板2。终端设备使用发送波束a,发送波束b分别发送上述两个PUSCH,网络设备使用相应的接收波束c,接收波束d分别接收上述两个PUSCH。
可选地,终端设备根据至少两个PDCCH指示的发送波束信息,确定不同的发送波束;使用不同的发送波束,发送至少两个PUSCH。相应地,网络设备使用不同的接收波束,接收至少两个PUSCH。
发送波束信息可以是空间关系信息(或TCI状态信息)。终端设备通过空间关系信息(或TCI状态信息)来确定发送波束的过程可以包括:网络设备通过RRC信令通知终端设备至少一个空间关系信息(或TCI状态信息),包括空间关系信息(或TCI状态信息)的标识及其对应的RS类型和RS标识;若RRC信令告知了多个空间关系信息(或TCI状态信息),则网络设备再使用MAC信令激活上述多个空间关系信息(或TCI状态信息)中的M个空间关系信息(或TCI状态信息),再用DCI信令指示M个中的其中一个空间关系信息(或TCI状态 信息),该被指示的空间关系信息(或TCI状态信息)即为网络设备给该终端设备的PUSCH的空间关系信息(或TCI状态信息),即告知终端设备发送PUSCH时使用的发送波束应当与该空间关系信息(或TCI状态信息)对应的RS所使用的发送波束相同或与终端设备接收该TCI状态对应的RS时的接收波束相对应的发送波束相同。之后,终端便可以使用上述确定的多个不同的发送波束,发送至少两个PUSCH。
下面,对至少两个PDCCH和至少两个数据信道(PDSCH或PUSCH)在时域上的顺序进行解释说明。
至少两个PDCCH在时域位置上相邻;或,第一PDCCH和第一数据信道在时域位置上相邻;其中,第一数据信道由第一PDCCH调度传输,第一PDCCH是至少两个PDCCH中的任意一个PDCCH。

终端设备在波束切换时间内,执行波束切换,不能传输PDCCH或数据信道。
示例性的,结合参考图4中的(a),由于使用不同的天线面板,所以PDCCH#1和PDCCH#2之间、PDCCH#2和数据#1之间、数据#1和数据#2之间都是需要天线面板的切换,若终端天线面板之间切换不需要时间,那么终端不需要空出符号用于波束切换;若终端天线面板之间切换需要时间,那么终端需要空出符 号用于波束切换。
