150,利用第三传输格式,在第三时频资源上,第二终端向网络设备发送第一数据。

因此,在本申请实施例中,第一终端将待发送数据中的一部分数据通过D2D传输的方式发送给第二终端,第一终端和第二终端分别独立发送待发送数据中的数据,由此,第一终端和第二终端可以看做是统一的天线阵列用于协同发送数据,在不增加终端的天线的基础上,可以达到更高阶数的MIMO传输的效果,可以实现5G所需的上行传输速率。
应理解,本申请各个附图描述的实施例中序号的大小不应是对执行过程的先后顺序的限定,各个过程的执行的先后顺序应该以实际情况而定。例如,对于图1所示的方法100中,第一数据和第二数据可以同时发送至网络设备。再例如,在110中,确定第一时频资源和第一传输格式的时间和第二时频资源和第二传输格式的时间可以分别在130之前和150之前。
本申请实施例可以应用于穿戴式设备的场景中,例如,如图2所示的通信场景200中,各个穿戴式设备可以建立D2D连接,各个穿戴式设备可以进行协同MIMO传输以向网络设备传输数据,其中,在图2中,手机作为第一终端,眼镜和手表作为第二终端,当然,也可以眼镜或手表作为第一终端,手机作为第二终端。
可选地,在本申请实施例中,第二终端在未获取到第一数据时(例如,未成功解码该第一数据),可以向基站发送上行反馈信息,用于指示第二终 端未获取该第一数据。其中,发送上行反馈信息的资源可以由基站进行分配。
可选地,第二终端在未获取到第一数据时,第二终端可以利用第三时频资源和所述第三传输格式进行其他上行数据的发送。第二基站并可以通过上行反馈信息通知基站,第二终端发送了其他的上行数据。
可选地,第二终端还可以向第一终端发送数据解码反馈信息,例如,如果解码成功,则可以反馈肯定确认(Acknowledge,ACK),如果解码失败,则可以反馈否定确认(Non-acknowledge,NACK)。
可选地,在本申请实施例中,第二时频资源和第三时频资源为相同的传输资源,可以进一步提高传输效率。
可选地,在本申请实施例中,可以通过网络设备对第一终端和/或第二终端进行调度,实现第一终端和第二终端协同发送数据。
具体地,网络设备确定第一信息、第二信息和第三信息中的至少一种信息;该第一信息包括第一时频资源和第一传输格式中的至少一种;该第二信息包括第二时频资源和第二传输格式中的至少一种;该第三信息包括第三时频资源和第三传输格式中的至少一种;该网络设备发送该至少一种信息。
例如,如图3所示的数据传输方法300,在310中,网络设备向第一终端发送用于指示第一时频资源、第二时频资源、第一传输格式和第二传输格式的信息,其中,用于指示第一时频资源和第一传输格式的信息和用于指示第二时频资源和第二传输格式的信息可以承载在同一消息中,或者是承载在不同的消息中,该不同的消息中,至少一个消息承载相互关联信息;在320中,网络设备向第二终端发送用于指示第一时频资源、第三时频资源、第一传输格式和第三传输格式的信息,其中,用于指示第一时频资源和第一传输格式的信息和用于指示第三时频资源和第三传输格式的信息可以承载在同一消息中,或者是承载在不同的消息中,该不同的消息中,至少一个消息承载相互关联信息;在330中,第一终端利用第一时频资源和第一传输格式向第二终端发送第一数据;在340中,第二终端利用第一时频资源和第一传输格式接收第一终端发送的数据,并利用第三时频资源和第三传输格式,向网络设备发送第一数据;在350中,第一终端利用第二时频资源和第二传输格式向网络设备发送第二数据。
在本申请实施例中,网络设备可以只为第一终端的上行传输分配时频资源和/或确定传输格式,或者网络设备可以只为第二终端的上行传输分配时频 资源和/或确定传输格式,或者网络设备可以只为第一终端到第二终端的数据传输分配时频资源和/或确定传输格式。
可选地,第一传输格式包括一个或多个传输块的调制编码方式、预编码向量、冗余版本以及传输新数据或重传数据的指示信息;第二传输格式包括一个或多个传输块的调制编码方式、预编码向量、冗余版本以及传输新数据或重传数据的指示信息;第三传输格式包括一个或多个传输块的调制编码方式、预编码向量、冗余版本以及传输新数据或重传数据的指示信息。

具体地说,由于第一信息指示的是向第二终端发送待发送数据的传输资源和传输格式,第二信息指示的是向网络设备发送待发送数据的传输资源和传输格式,第一信息和第二信息之间的关联关系需要告知给第一终端,则可以通过将该第一信息和第二信息承载在同一消息中,从而可以隐性体现该关联关系,由此第一终端可以获知第一信息指示的时频资源和传输格式用于向第二终端发送待发送数据中的第一数据,第二信息指示的时频资源和传输格式用于向网络设备发送待发送数据中的第二数据;或者可以将第一信息和第二信息承载在不同消息中,则需要至少一个消息显性指示该关联关系。
类似地,在本申请实施例中,在网络设备发送第一信息和第三信息时,网络设备将第一信息和第三信息承载在同一消息发送给第二终端。或,在网络设备发送第一信息和第三信息时,网络设备将第一信息和第三信息承载在不同的消息发送给第二终端,该不同的消息中至少一种消息用于指示第一信息和第三信息的关联关系。
可选地,在本申请实施例中,第一终端可以和至少一个终端分别建立D2D连接(也可以称为副链路(sidelink)连接。第一终端可以将该至少一个终端的标识通过通知消息发送给网络设备,则网络设备可以从该至少一个终端中选择第二终端,用来协助第一终端向网络设备发送上行数据。其中,网络设备可以选择多个终端,用来协助第一终端向网络设备发送上行数据。
其中,该通知消息还可以进一步包括与第一终端建立D2D连接的至少 一个终端的能力信息,例如,终端传输带宽和/或天线数量等。
可选地,第一终端可以周期性发送该通知消息,如果与该第一终端建立D2D连接的终端随着时间变化,则该通知消息携带的终端的信息也随之变化。
可选地,在本申请实施例中,网络设备基于第一信道状态信息、第二信道状态信息、第三信道状态信息和至少一个终端的能力信息的至少一种,确定所述第二终端;其中,第一信道状态信息为第一终端与网络设备之间的上行信道的状态信息;第二信道状态信息为第一终端向与该第一终端建立D2D连接的至少一个终端中的终端传输数据的信道的状态信息;第三信道状态信息为该至少一个终端中的终端与网络设备之间的上行信道的状态信息。
例如,网络设备可以将能力较强的终端,和/或与网络设备之间的信道状态较好的终端,和/或与第一终端之间的信道状态较好的终端确定为第二终端。
例如,网络设备可以基于第一终端与网络设备之间的信道状态,确定第一终端与网络设备可以传输的数据量,则基于剩下的数据的数据量,并依据第三信道状态信息、第二信道状态信息和终端的能力信息,来选择第二终端。
可选地,在本申请实施例中,网络设备可以基于第一信道状态信息、第二终端对应的第二信道状态信息、第二终端对应的第三信道状态信息,或基于第一信道状态信息、所述第二终端对应的第二信道状态信息、所述第二终端对应的第三信道状态信息和第二终端的能力信息,确定第一信息、第二信息和第三信息。其中,第二终端对应的第三信道状态信息为第二终端与网络设备之间的上行信道的状态信息,第二终端对应的第二信道状态信息为第一终端向第二终端传输数据的信道的状态信息。
例如,网络设备可以参考第一信道状态信息、第二信道状态信息和第三信道状态信息,综合评估各个传输信道的特性,并进行传输格式和时频资源的分配。
例如,网络设备可以基于第一终端与网络设备之间的信道状态,确定第一终端与网络设备可以传输的数据量,以及如果第二终端包括多个终端,则可以依据各个第二终端与第一终端之间的信道状态和各个第二终端与网络设备之间的上行信道的信道状态,确定需要各个第二终端传输的数据量。
以上已经介绍了网络设备如何利用第一信道状态信息,和/或第二信道状 态信息,和/或第三信道状态信息进行调度。以下将说明网络设备如何获取第一信道状态信息、第二信道状态和第三信道状态信息。
在本申请实施例中,网络设备可以向第一终端发送第一信道探测参考信号请求;第一终端接收到该第一信道探测参考信号请求之后,向网络设备发送第一信道探测参考信号;网络设备基于该第一信道探测参考信号,获取该第一信道状态信息。
其中,在网络设备向第一终端发送第一信道探测参考信号请求之前,第一终端可以向网络设备发送上行资源调度请求,该请求可以包括调度请求(Scheduling Request,SR)和缓存状态报告(Buffer Status Report,BSR),并可以周期性性上报这些信息。
在本申请实施例中,第一终端可以向与该第一终端之间建立D2D连接的至少一个终端发送第二信道探测参考信号;该至少一个终端中的每个终端基于该第二信道探测参考信号,确定第二信道状态信息;在网络设备接收到第一终端发送的携带该至少一个终端的标识的通知消息之后,可以向该至少一个终端发送第二信道状态信息请求,该至少一个终端中的每个终端向该网络设备发送第二信道状态信息。
其中,第一终端可以向与该第一终端建立D2D连接的至少一个终端周期性发送第二信道探测参考信号。与该第一终端建立D2D连接的至少一个终端可以周期性向网络设备发送第二信道状态信息。
其中,在网络设备向与第一终端建立D2D连接的至少一个终端中的某个终端发送第二信道状态信息求之前,如果该终端还未与网络建立连接,则可以请求该终端发起建立与网络的连接。
在本申请实施例中,网络设备可以向与第一终端建立D2D连接的至少一个终端发送第三信道探测参考信号请求;该至少一个终端中的每个终端接收到该第三信道探测参考信号请求之后,可以分别向网络设备发送第三信道探测参考信号;网络设备基于每个终端发送的第三信道探测参考信号,确定每个终端对应的第三信道状态信息。
其中,在网络设备向与第一终端建立D2D连接的至少一个终端中的某个终端发送第三信道探测参考信号请求之前,如果该终端还未与网络建立连接,则可以请求该终端发起建立于网络的连接。
可选地,第三信道探测参考信号请求用于指示的发送第三探测参考信号 的时间点与第一信道探测参考信号请求用于指示的发送第一探测参考信号的时间点相同,也即,第一终端向网络设备发送探测参考信号的时间与与该第一终端建立D2D连接的终端向网络设备发送探测参考信号的时间保持一致,由此网络设备可以更好的综合评估各个上行信道之间的信道相关性。
为了更好地理解本申请,以下将以图4所示的场景400为例,结合图5描述根据本申请实施例的数据传输方法500。
图4所示的系统由网络设备和若干个终端构成,它们相互之间通过两种空中接口相互通信:网络设备与终端之间的空中接口为Uu接口,从网络设备到终端的通信链路为Uu下行链路(Downlink,DL),从终端到网络设备的通信链路为Uu上行链路(Uplink,UL)。终端与终端之间的空中接口为Sidelink空中接口(SL)。
每个终端均可发送和接收Uu信号和SL信号,针对每个Uu上行数据流,发起数据流的终端称为“发送终端”,通过协同MIMO方式协助发送终端发送该数据流的终端称为“协同终端”。一个发送终端可以同时向多个协同终端发送不同的SL数据,并与多个协同终端协同发送一个上行数据流。
网络设备可以接收来自终端的上行调度请求(UL SR)、UL信道探测参考信号(UL SRS)、SL信道状态信息(SL CSI)报告,网络设备可以向终端发送UL SRS请求、SL信道探测参考信号(SL SRS)请求、SL CSI报告请求、UL资源分配信息(UL Grant)、SL资源分配信息(SL Grant)、SL调度配置(Scheduling Assignment,SA)信息(SL SA)。

协同终端可以接收来自网络设备的UL SRS请求、UL Grant、SL CSI报告请求、SL SA,接收来自发送终端的SL SRS和SL数据,协同终端可以向网络设备发送UL SRS、SL CSI报告和UL数据。
其中,假设发送终端已处于和网络设备的Uu连接状态,协同终端可能未处于与网络设备的Uu连接状态。发送终端可能尚未建立与协同终端SL连接。发送终端有Uu上行数据流需要向网络设备发送。
501,发送终端和可能的协同终端建立SL连接,包括发送终端可以向可能的协同终端周期性发送SL信道探测参考信号(SL SRS),可能的协同终 端可以向发送终端周期性反馈SL信道状态信息(SL CSI)。其中,该可能的协同终端可以是能够与发送终端建立SL连接的终端。
502,发送终端将建立SL连接的可能的协同终端的信息发送给网络设备,并可以周期性的更新该信息(可能的协同终端可以随时变化)。该信息至少包括可能的协同终端的标识信息,可供网络设备识别哪些终端可与发送终端协同,还可以进一步包括可能的协同终端的能力信息,如终端传输带宽、天线数量等。
503,发送终端向网络设备发送上行资源调度请求,该上行资源调度请求可以包括调度请求(Scheduling Request,SR)和缓存状态报告(Buffer Status Report,BSR),并可以周期性的上报这些信息(因为BSR会不断变化)。

可选地,该UL SRS请求配置的SRS发送时间周期以及时间点与504中UL SRS请求配置的SRS发送时间周期以及时间点相同。
506,那些没有与网络设备建立Uu连接的可能的协同终端,收到网络设备的信令后,与网络设备建立Uu连接。
507,可能的协同终端根据网络设备的请求,向网络设备发送UL SRS,并可以周期性发送。
508,可能的协同终端向网络设备上报从发送终端到该协同终端的SL CSI,并可以周期性发送。
509,网络设备根据发送终端和可能的协同终端上报的UL SRS及上报的SL CSI信息,综合评估发送终端和各可能的协同终端的UL链路及从发送终端到各可能的协同终端的SL链路的的链路特性,从发送终端和各可能的协同终端中,选择适合参与上行协同MIMO传输的终端,作为协同终端,多个协同终端可以称为协同终端组。
510,网络设备根据发送终端和选中的协同终端上报的UL SRS及上报的SL CSI信息,和/或各协同终端的能力信息,来确定需要发送给发送终端 的上行资源分配信息(UL Grant)和Sidelink资源分配信息(SL Grant),以及需要发送给协同终端的SL调度配置信息和UL grant;
网络设备向发送终端发送上行资源分配信息(UL Grant)和Sidelink资源分配信息(SL Grant),包含向509中各个被选中的协同终端的SL Grant。针对每个被选中的协同终端的SL Grant包括该终端的标识信息、向该协同终端发送数据所采用的SL时频资源、传输格式,以及指示该SL Grant用于发送发送终端的上行数据而非Sidelink数据的信息。
可选地,510可以有两种实现方式:
方式1:网络设备向发送终端发送一条下行控制信令,该下行控制信令包含上述UL Grant和针对每个被选中的协同终端的SL Grant,UL Grant和每个SL Grant分别包含一个或多个传输块(Transport Block,TB)的传输格式信息,该信息至少包含该TB的调制编码格式(如Modulation and Coding Scheme(MCS)和Redundancy Version(RV))及该TB是用来传输新数据还是重传数据的指示等。此方法可隐性地说明:这些SL Grant是用于发送发送终端的上行数据而非Sidelink数据的。
方式2:网络设备向发送终端发送多条下行控制信令,分别对应上述UL Grant和针对每个被选中的协同终端的SL Grant,每条信令包含一个或多个传输块(Transport Block,TB)的传输格式信息,该信息至少包含该TB的调制编码格式(如Modulation and Coding Scheme(MCS)和Redundancy Version(RV))及该TB是用来传输新数据还是重传数据的指示,每条携带SL Grant的信令包含指示该SL Grant用于发送发送终端的上行数据而非Sidelink数据的信息。此方法显性地说明:这些SL Grant是用于发送发送终端的上行数据而非Sidelink数据的。
可选地,网络设备还可以向发送终端发送指示信息,该指示信息用于指示协同终端向发送终端发送ACK或NACK的时频资源。该指示信息可以承载在上述包括UL grant和/或SL grant的下行控制信令中。
511,网络设备向509中被选中的协同终端发送SL调度配置信息(SL Scheduling Assignment,SL SA),包含发送终端将向该协同终端发送SL数据的时频资源和传输格式,以便该协同终端接收相应的SL数据。网络设备向509中被选中的各个协同终端分别发送UL Grant,包含可供该终端使用的时频资源、传输格式等。且网络设备向上述每个终端指示发给它的上述SL SA 和UL Grant之间的关联性(即该UL Grant是用于发送从该SL SA收到的数据的,而不是用来发送自身的上行数据的)。
针对各协同终端的UL Grant可采用相同的时频域资源,可以与510中给发送终端的UL Grant包含的时频资源相同。
可选地,511可以有以下两种实现方式:
方式1:网络设备向每个协同终端发送一条包含上述SL SA和UL Grant的下行控制信令,SL SA和UL Grant分别包含一个或多个传输块(Transport Block,TB)的传输格式信息,该信息至少包含该TB的调制编码格式(如Modulation and Coding Scheme(MCS)和Redundancy Version(RV))及该TB是用来传输新数据还是重传数据的指示。此方法可隐性地说明:该UL Grant是用于发送在该SL SA接收到的发送终端的上行数据而非其他待发的上行数据的。
方式2:网络设备向每个协同终端发送一条包含上述SL SA的下行控制信令和一条包含上述UL Grant的下行控制信令,SL SA和UL Grant分别包含一个或多个传输块(Transport Block,TB)的传输格式信息,该信息至少包含该TB的调制编码格式(如Modulation and Coding Scheme(MCS)和Redundancy Version(RV))及该TB是用来传输新数据还是重传数据的指示。在这两条信令的至少其中一条包含指示上述SL SA和UL Grant之间的关联关系,即指明该UL Grant是用于发送采用该SL SA接收的数据而非其他待发的上行数据的。
可选地,网络设备还可以向协同终端发送指示信息,该指示信息用于指示协同终端向发送终端发送ACK或NACK的时频资源。该指示信息可以承载在上述包括UL grant和/或SL SA的下行控制信令中。
512,发送终端按照510的SL Grant向各协同终端发送SL数据。
513,发送终端采用510中收到的UL Grant发送上行数据。
514,各协同终端采用511中收到的UL Grant发送上行数据,该数据来自512中收到的SL数据。
如果某协同终端成功解码了512中从发送终端收到的SL数据,则该终端采用511中收到的UL Grant发送此SL数据;并可以向发送终端反馈SL_ACK消息。
