- NR has two levels of retransmission mechanisms: the HARQ mechanism at the Medium Access Control (MAC) layer and the HARQ mechanism at the Radio Link Control (RLC) layer.

- the stop-and-wait protocol after the sender sends a TB, it stops and waits for the confirmation message. In this way, the sender will stop and wait for confirmation after each transmission, which will result in very low user throughput. Therefore, NR uses multiple parallel HARQ processes. When one HARQ process is waiting for confirmation information, the sender can use another HARQ process to continue sending data. These HARQ processes together form a HARQ entity, which combines the stop-and-wait protocol to allow continuous data transmission.
- HARQ is divided into uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission, and downlink HARQ is for downlink data transmission, and the two are independent of each other.

- a two-step resource configuration method is adopted: first, the network RRC configures the transmission resources and transmission parameters including the period of time domain resources, the number of repetitions, the frequency hopping, the number of HARQ processes, etc.; and then the PDCCH scrambled by the CS-RNTI Activate the second type of PUSCH transmission based on configuration authorization, and configure other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, etc. at the same time.

下面对本申请实施例涉及到的部分背景相关知识进行介绍。
NTN相关背景
目前3GPP正在研究NTN技术,NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信,卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如,一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,而对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面,加之卫星可以围绕地球做轨道运动,因此,理论上地球上每一个角落都可以被卫星通信覆盖。其次,卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小与发达地区的数字鸿沟,促进这些地区的发展。再次,卫星通信距离远,且通信距离增大,通讯的成本没有明显增加;最后,卫星通信的稳定性高,不受自然灾害的限制。
通信卫星按照轨道高度的不同分为低地球轨道(Low-Earth Orbit,LEO)卫星、中地球轨道(Medium-Earth Orbit,MEO)卫星、地球同步轨道(Geostationary Earth Orbit,GEO)卫星、高椭圆轨道(High Elliptical Orbit,HEO)卫星等等。目前阶段主要研究的是LEO和GEO。
1.LEO
低轨道卫星高度范围为500km~1500km,相应轨道周期约为1.5小时~2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短,链路损耗少,对用户终端的发射功率要求不高。
2.GEO
地球同步轨道卫星,轨道高度为35786km,围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信***的***容量,卫星采用多波束覆盖地面,一颗卫星可以形成几十甚至数百个波束来覆盖地面;一个卫星波束可以覆盖直径几十至上百公里的地面区域。
NR HARQ机制
NR有两级重传机制:媒质接入控制(Medium Access Control,MAC)层的HARQ机制和无线链路控制(Radio Link Control,RLC)层的HARQ机制。丢失或出错的数据的重传主要是由MAC层的HARQ机制处理的,并由RLC层的重传功能进行补充。MAC层的HARQ机制能够提供快速重传,RLC层的ARQ机制能够提供可靠的数据传输。
HARQ使用停等协议(Stop-and-Wait Protocol)来发送数据。在停等协议中,发送端发送一个TB后,就停下来等待确认信息。这样,每次传输后发送端就停下来等待确认,会导致用户吞吐量很低。因此,NR使用多个并行的HARQ进程,当一个HARQ进程在等待确认信息时,发送端可以使用另一个HARQ进程来继续发送数据。这些HARQ进程共同组成了一个HARQ实体,这个实体结合了停等协议,允许数据连续传输。HARQ有上行HARQ和下行HARQ之分。上行HARQ针对上行数据传输,下行HARQ针对下行数据传输,两者相互独立。
CG/SPS
为了更好地服务于周期性的业务,引入了预配置的资源的概念,下行称为半持续调度(Semi-Persistent Scheduling,SPS),上行称为配置授权(Configured Grant,CG)。
对每个SPS配置来说,网络为其配置有限个数的下行HARQ进程,网络采用轮询的方式使用这些下行HARQ进程在SPS资源上进行下行传输。
SPS采用两步资源配置的方式:首先,由网络RRC配置包括时域资源的周期、HARQ进程数等在内的传输资源和传输参数;然后由使用配置调度无线网络临时标识(Configured Scheduling RNTI,CS-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel,PDCCH)激活基于SPS的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输,并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。UE在接收到RRC配置参数时,不能立即使用该RRC配参数配置的资源和参数进行PDSCH接收,而必须等接收到相应的PDCCH激活并配置其他资源和参数后,才能进行PDSCH接收。
基于目前NR协议的规定,终端对应每个服务小区都有各自的HARQ实体。每个HARQ实体维护一组并行的下行HARQ进程和一组并行的上行HARQ进程。目前每个上下行载波均支持最大16个HARQ进程。基站可以根据网络部署情况通过RRC信令半静态配置向UE指示最大的HARQ进程数。如果网络没有提供相应的配置参数,则下行缺省的HARQ进程数为8,上行每个载波支持的最大HARQ进程数始终为16。每个HARQ进程对应一个HARQ进程标识(ID)。对于下行,广播控制信道(Broadcast Control Channel,BCCH)使用一个专用的广播HARQ进程。对于上行,随机过程中的Msg3传输使用HARQ ID 0。
对于不支持下行空分复用的终端,每个下行HARQ进程只能同时处理1个TB;对于支持下行空分复用的终端,每个下行HARQ进程可以同时处理1个或者2个TB。终端的每个上行HARQ进程同时处理1个TB。
HARQ在时域上分为同步和异步两类,在频域上分为非自适应和自适应两类。NR上下行均使用异 步自适应HARQ机制。异步HARQ即重传可以发生在任意时刻,同一个TB的重传与上一次传输的时间间隔是不固定的。自适应HARQ即可以改变重传所使用的频域资源和调制与编码策略(Modulation and Coding Scheme,MCS)。
对每个CG配置来说,网络为其配置有限个数的上行HARQ进程号,UE采用轮询的方式使用这些上行HARQ进程在CG资源上进行上行传输。
NR支持以下两类上行免授权传输:
1.基于第一类配置授权(configured grant Type 1)的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输
由网络RRC配置包括时域资源、频域资源、时域资源的周期、MCS、重复次数、跳频、HARQ进程数等在内的全部传输资源和传输参数。终端接收到该RRC配置后,可立即使用所配置的传输参数在配置的时频资源上进行PUSCH传输。
2.基于第二类配置授权(configured grant Type 2)的PUSCH传输
采用两步资源配置的方式:首先,由网络RRC配置包括时域资源的周期、重复次数、跳频、HARQ进程数等在内的传输资源和传输参数;然后由使用CS-RNTI加扰的PDCCH激活第二类基于配置授权的PUSCH传输,并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。UE在接收到RRC配置参数时,不能立即使用该配参数配置的资源和参数进行PUSCH传输,而必须等接收到相应的PDCCH激活并配置其他资源和参数后,才能进行PUSCH传输。
如果UE没有数据需要在第一类和第二类配置授权的PUSCH资源上发送,UE不会在配置授权的资源上发送任何内容。
与传统NR采用的蜂窝网络相比,NTN中UE与卫星之间的信号传播时延大幅增加,为了在不增加HARQ进程数目的情况下保证数据传输连续性,目前标准化过程中已经同意可以关闭HARQ进程的HARQ反馈功能,并形成了以下明确的结论:
1、网络设备可以配置是否开启HARQ功能。
2、如果HARQ功能关闭,则UE不需要向网络设备发送针对PDSCH的HARQ反馈。
3、在关闭HARQ反馈的情况下,为了保证数据传输可靠性,仍然支持基于盲调度的HARQ重传。
4、可以基于UE或者基于HARQ进程进行HARQ功能开启或关闭的配置。对于基于UE的配置的方式,即配置UE的所有HARQ进程的HARQ功能同时处于开启或关闭状态。对于基于HARQ进程的配置方式,即对于一个UE的多个HARQ进程,可以配置其中一部分HARQ进程的HARQ功能为开启状态,另一部分HARQ进程的HARQ功能为关闭状态。
5、需要分别研究开启HARQ和关闭HARQ这两种情况下,对其他过程的影响。
基于目前的标准化结论,在关闭HARQ进程的HARQ反馈功能的情况下,为了保证数据传输的可靠性,网络可以盲调度重传,即对于下行传输,网络在没有来自UE的ACK/NACK反馈信息的情况下,可以通过多次调度同一个下行TB的重传来提高下行传输的鲁棒性;对于上行传输,网络在接收到来自UE的PUSCH传输之前,可以通过多次调度同一个上行TB的重传来提高上行传输的鲁棒性。但是,这种动态调度HARQ重传的方法,每次调度时,网络设备需要发送PDCCH信令,会带来大量的PDCCH信令开销。
本申请提供的数据传输方法可以解决现有的动态调度HARQ重传的方法的代价是会带来大量的PDCCH信令开销这一技术问题。需要说明的是,本申请的数据传输方法并不仅限于解决上述技术问题,还可以用以解决其它的技术问题,本申请中不加以限制。
图1为本申请实施例提供的数据传输方法的应用场景示意图。如图1所示,该场景包括网络设备104和终端102,其中,终端102与网络设备104通过网络进行通信。网络设备104可以调度资源,例如,网络设备104配置传输资源,即使在为配置授权预留的HARQ进程的HARQ反馈功能都处于关闭状态时,使用网络设备发送的资源配置信息确定数据传输资源的捆绑(bundling)关系,在具有相同捆绑关系的数据传输资源上进行数据收发。其中,终端102可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备,网络设备104可以是基站等,例如,可以用独立的基站或者是多个基站组成的基站集群来实现。
图2为一个实施例提供的一种数据传输方法的流程图。本实施例涉及的是终端接收网络设备发送的资源配置信息,根据资源配置信息确定数据传输资源的捆绑关系,并在具有相同捆绑关系的数据传输资源进行数据的收发的具体实现过程。如图2所示,该方法可以包括以下步骤:
S201、终端根据网络设备发送的数据传输资源的资源配置信息,确定所述数据传输资源的捆绑关系。
其中,资源配置信息中可以包括为终端的每个服务小区配置的工作带宽(Bandwidth part,BWP),也可以包括为每个BWP配置的传输资源配置,例如,BWP可以为下行(Down Link,DL)BWP,也可以为上行(Up Link,UL)BWP,每个BWP可以至少配置一个传输资源配置,该至少一个传输资源配置可以为下行资源配置,也可以为上行资源配置,例如,该传输资源配置可以为SPS配置,也可以为CG配置,而且,每个BWP对应的传输资源配置的数量不限定,可以为每个BWP配置一个传输资源配置,也可以是为每个BWP配置多个传输资源配置,例如,为终端的每个服务小区的DL BWP配置一个SPS配置,为终端的每个服务小区的UP BWP配置一个CG配置,或者,为终端的每个服务小区的DL BWP配置多个SPS配置,为终端的每个服务小区的UP BWP配置多个CG配置,可根据实际需求来配置,本实施例不加以限制。传输资源配置中可以包括资源周期、为传输资源预留的HARQ进程数、HARQ进程的标识(ID)、HARQ进程的HARQ反馈功能状态、重传次数等,还可以包括其他的参数,本申请实施例中不加以限制。
可选地,该资源配置信息可以携带在无线资源控制(Radio Resource Control,RRC)信令中。
在本实施例中,终端可以在接收到该资源配置信息后,确定各数据传输资源的bundling关系,在 具有相同捆绑关系的数据传输资源上进行数据收发。例如,终端可以根据资源配置信息,从一个特定的数据传输资源开始,将多个时域相邻的数据传输资源确定为一组具有相同绑定关系的数据传输资源。例如,资源配置信息中配置了4个SPS资源,终端可以从时域最早的SPS资源开始,将时域相邻的4个SPS资源绑定为一组,或者,资源配置信息中配置了3个CG资源,终端可以从时域最早的CG资源开始,将时域相邻的3个CG资源绑定为一组。不同的数据传输资源可以具有不同的捆绑关系,本申请实施例中不加以限制。
S202、终端通过具有相同捆绑关系的数据传输资源进行数据的收发。
在本实施例中,终端接收到该资源配置信息后,根据资源配置信息确定各数据传输资源的捆绑关系,并在具有相同捆绑关系的数据传输资源进行数据的收发,即使为数据传输资源预留的HARQ进程的HARQ反馈功能均处于关闭状态,也可以在网络设备配置的数据传输资源上进行数据收发,无需网络设备动态调度。例如,若网络设备为终端的每个服务小区的DL BWP配置了多个SPS资源,则UE在具有相同捆绑关系的SPS资源上接收数据。或者,若网络设备为终端的每个服务小区的UL BWP配置了多个CG资源,则UE在具有相同捆绑关系的一组CG资源上发送数据。
本申请实施例提供的数据传输方法,终端根据网络设备发送的数据传输资源的资源配置信息,确定所述数据传输资源的捆绑关系,并通过具有相同捆绑关系的数据传输资源进行数据的收发,即使为数据传输资源预留的HARQ进程的HARQ反馈功能均处于关闭状态,也可以在通过网络设备发送的资源配置信息确定数据传输资源的捆绑关系之后,在具有相同捆绑关系的数据传输资源上进行数据收发,也即,在具有相同绑定关系的的数据传输资源上进行数据重复接收或发送,在关闭HARQ反馈功能的情况下保证数据传输可靠性,而且,在关闭HARQ反馈功能的情况下,可以直接使用具有相同捆绑关系的数据传输资源进行数据接收或发送,无需网络设备多次通过PDCCH信令调度数据传输资源,避免带来大量的PDCCH信令开销。
在一些场景中,数据传输资源需要被激活才能使用,例如,对于SPS资源或者是使用Type 2的CG资源,都需要进行激活后终端才能实现数据收发,因此,在一个实施例中,数据传输资源为激活的数据传输资源,步骤S201“终端根据数据传输资源的资源配置信息,确定数据传输资源的捆绑关系,”包括:终端根据激活的数据传输资源和数据传输资源的资源配置信息,确定数据传输资源的捆绑关系。
在本实施例中,上述数据传输资源可以为被激活的数据传输资源,激活方式可以有多种,例如,网络设备在发送配置信息之后,再通过PDCCH信令进行数据传输资源的激活,或者,网络设备也可以先确定终端所需的数据传输资源,然后通过PDCCH信令激活该数据传输资源,再向终端发送资源配置信息,或者,网络设备也可以通过资源配置信息来激活数据传输资源,或者,网络设备还可以采用其他的方式激活数据传输资源,本申请实施例中并不一次为限。终端在激活的数据传输资源上进行数据重复接收或发送,保证了数据重复接收或者发送的可靠性。
在一些场景中,网络设备可以为终端的每个服务小区的BWP配置一个数据传输资源,在另一些场景中,网络设备可以为终端的每个服务小区的BWP配置多个传输资源。下面通过不同的场景分别详细介绍本申请实施例提供的数据传输方法。
场景一:网络设备为终端配置多个SPS资源
在一个实施例中,数据传输资源包括N个半持续调度SPS资源,资源配置信息包括N个SPS配置,N为大于1的整数。
在本实施例中,网络设备可以为终端的每个服务小区的每个DL BWP配置N个SPS资源,则该资源配置信息中包括该N个SPS资源对应的SPS配置。可选地,N的取值为根据网络期望同一个传输块TB使用传输资源重复接收的次数确定的,也即,N的取值取决于网络期望同一个TB使用SPS资源重复接收的次数。如图3所示,网络设备为终端配置了SPS资源1、SPS资源2、SPS资源3、SPS资源4,可以将同一个SPS周期内的4个SPS资源确定为具有相同捆绑关系的一组SPS资源,终端可以通过具有相同捆绑关系的一组SPS资源进行数据接收。
其中,各SPS配置包括:SPS资源周期、预留给SPS资源的混合自动重复请求HARQ进程数、HARQ进程的标识、HARQ进程的HARQ反馈功能状态信息和N个SPS配置的关系指示信息;关系指示信息用于指示N个SPS配置中的基准SPS配置和各SPS配置的相对时间偏移量,相对时间偏移量表示各SPS配置的时域资源的起始位置相对于基准SPS配置的时域资源的起始位置的偏移量。可选地,相对时间偏移量大于或等于0,且,各SPS配置的相对时间偏移量互不相等。
在本实施例中,该N个SPS配置对应相同的SPS资源周期;为N个SPS配置预留相同的下行HARQ进程数,以及为N个SPS配置设置相同的下行HARQ进程ID,并且这些预留给SPS的下行HARQ进程的HARQ反馈功能都处于关闭状态;而且,N个SPS配置都没有配置相应的用于反馈ACK/NACK的PUCCH资源。
在本实施例中,网络设备可以采用多种方式指示基准SPS配置,例如,在N个SPS配置中的一个SPS配置上设置一个基准标识,带基准标识的SPS配置即为基准SPS配置,或者,将基准SPS配置的相对时间偏移量设置为0,或者,为N个SPS配置中的其余N-1个SPS配置分别配置一个相对时间偏移量,没有设置相对时间偏移量的SPS配置默认为基准SPS配置,等等,本申请实施例中不加以限制。
进一步地,如图4所示,步骤S201“终端根据网络设备发送的数据传输资源的资源配置信息,确定所述数据传输资源的捆绑关系”,包括:
S401、终端从基准SPS配置对应的资源开始,将N个时域相邻的SPS资源确定为一组具有相同绑定关系的SPS资源;N个时域相邻的SPS资源分别与N个SPS配置相对应。
在本实施例中,如图3所示,网络设备为终端配置了4个SPS资源,从左向右,将最左边的SPS资源1确定为基准SPS资源,将相邻的SPS资源1、SPS资源2、SPS资源3和SPS资源4确定为一组具有相同捆绑关系的SPS资源,位于同一组bundling的N个SPS资源分别对应于N个SPS配置,并且映射到相同的HARQ进程号。
S402、终端采用轮询的方式,将预留给N个SPS资源的HARQ进程的标识依次关联到各组具有相同绑定关系的SPS资源上,一组具有相同绑定关系的SPS资源对应的HARQ进程的标识相同。
在本实施例中,对于网络设备配置的N个SPS资源中的每一个SPS资源,分别采用轮询的方式将预留给SPS资源的下行HARQ进程号依次关联到各组具有相同捆绑关系的SPS资源上。如图3所示,为SPS资源预留的下行HARQ进程号为HARQ#0和HARQ#1,N=4,则将HARQ#0关联到SPS配置1、SPS配置2、SPS配置3和SPS配置4上,再将则将HARQ#1关联到SPS配置1、SPS配置2、SPS配置3和SPS配置4上,以此方式轮询关联。
本申请实施例提供的数据传输方法,终端从基准SPS配置对应的资源开始,将N个时域相邻的SPS资源确定为一组具有相同绑定关系的SPS资源,终端采用轮询的方式,将预留给N个SPS资源的HARQ进程的标识依次关联到各组具有相同绑定关系的SPS资源上,N个时域相邻的SPS资源分别与N个SPS配置相对应,一组具有相同捆绑关系的SPS资源对应的HARQ进程的标识相同,终端可以在一组具有相同捆绑关系的传输资源上重复接收或者发送数据,保证数据重复传输的可靠性。
再进一步地,步骤S202“终端通过具有相同捆绑关系的数据传输资源进行数据的收发,”包括:终端通过具有相同绑定关系的N个SPS资源进行数据接收,并将接收M次的数据包采用同一个HARQ进程进行缓存;M小于或等于N。
在本实施例中,终端可以在位于同一个bundling的N个SPS资源上接收数据,并将接收到M次的数据包采用同一个HARQ进程进行缓存,最多将N次接收到的数据包使用同一个HARQ进程进行缓存。对于位于同一个bundling的N次下行接收,后面接收的数据不会覆盖前面接收的数据。终端将接收到的多次数据包进行合并解码。由于在具有相同捆绑关系的的一组SPS资源上重复接收同一个数据包,使得终端可以准确的进行数据包的合并和解码,保证数据重复传输的准确性。
