Description

生效时间的确定方法、终端及网络设备 技术领域
本申请涉及通信领域,具体而言,涉及一种生效时间的确定方法、终端及网络设备。
背景技术
在相关技术中,下行MAC CE(Medium Access Control Control Element,媒质接入控制控制单元)所指示的下行配置的生效时间,都是由UE基于携带该MAC CE的PDSCH的HARQ(Hybrid Automatic Repeat Request,混合自动重复请求)功能的反馈时间点得到的。例如,MAC CE指示的SCell(Secondary Cell,辅服务小区)激活去激活的生效时间和MAC CE指示的TCI state(Transmission Configuration Indicator state,传输配置指示)切换时间,都是由UE(终端)针对携带该MAC CE的PDSCH(Physical Downlink Shared Channel,物理下行共享信道)的ACK(Acknowledgement,确认)反馈时间点推算得到。如果使用关闭HARQ反馈功能的PDSCH传输这些MAC CE,由于不存在针对该PDSCH传输的ACK反馈的时间点,原来的MAC CE生效时间确定方法不再适用。针对这种情况,如何确定MAC CE指示的下行配置的生效时间,明确UE的行为,是需要从标准层面解决的问题。

为对本发明实施例进行清楚的描述,先对本申请所涉及的相关技术进行说明。
NTN相关技术
NTN(Non-Terrestrial Network,非地面通信网络)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LEO(Low-Earth Orbit,低地球轨道)卫星、MEO(Medium-Earth Orbit,中地球轨道)卫星、GEO(Geostationary Earth Orbit,地球同步轨道)卫星、HEO(High Elliptical Orbit,高椭圆轨道)卫星等等。下面主要对LEO和GEO进行举例说明。
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。
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系统的系统容量,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(New Radio,新无线)有两级重传机制:MAC(Medium Access Control,媒质接入控制)层的HARQ(Hybrid Automatic Repeat Request,混合自动重复请求)机制和RLC(Radio Link Control,无线链路控制)层的ARQ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。
基于NR协议的相关规定,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ID。对于下行,BCCH(Broadcast Control CHannel,广播控制信道)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(Transport Block,传输块)。
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MCS(Modulation and Coding Scheme,调制与编码策略)。
NR下行调度和下行数据传输
网络在给终端传输下行数据之前,需要先为给该终端的下行传输分配合适的时频域资源,并通过承载调度信令的PDCCH(Physical Downlink Control Channel,物理下行控制信道)告知终端,PDCCH中包含分配的时频域资源位置,MCS,使用的下行HARQ进程ID,初传重传指示等等。终端根据收到的PDCCH指示在对应的资源上使用指示的HARQ进程接收下行数据。
终端接收下行数据的过程如下:
如果终端接收到的是初传数据,并且对应的HARQ进程的缓存中当前没有其他数据,则终端将接收的下行数据放入对应的HARQ进程的缓存中,并对该数据进行解码。
如果终端接收到的是初传数据,并且对应的HARQ进程的缓存中已有其他数据,则终端将本次接收的下行数据替换该HARQ进程的缓存中的已有数据放入该HARQ进程的缓存中,并对该数据进行解码。
如果终端接收到的是重传数据,则终端将本次接收的下行数据与对应HARQ进程的缓存中的已有数据进行软合并,并对合并后的数据进行解码。
终端如果解码成功,则向网络发送ACK反馈,网络在收到ACK后,就可以使用该HARQ进程继续调度新传数据。终端如果解码失败,则向网络发送NACK反馈,网络在收到NACK后,由网络决定是使用该HARQ继续调度该数据块的重传还是放弃该数据块调度新传数据。在网络收到来自终端的针对某个HARQ进程的ACK/NACK 反馈之前,不能使用该HARQ进程进行数据传输。
为了增强覆盖,NR还支持下行bundling(绑定)传输,即对于同一个下行TB,网络在相同的频域资源上连续地重复发送多次,终端在完成一个bundling的接收后对接收到的数据一并进行解码。下行bundling包含的重复传输次数由网络RRC(Radio Resource Control,无线资源控制)配置。
下行配置授权
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SPS(Semi-Persistent Scheduling,半持续调度),上行称为CG(Configured Grant,配置授权)。
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CS-RNTI加扰的PDCCH激活基于SPS的PDSCH传输,并同时配置包括时域资源,频域资源,MCS,ACK/NACK(Acknowledgement/Non-Acknowledgement,确认/非确认)反馈时域资源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PDSCH(Physical Downlink Shared Channel,物理下行共享信道)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。
MAC CE指示的SCell激活去激活生效时间
如果UE在时隙n收到MAC CE指示UE激活某个SCell(Secondary cell,辅服务小区),则UE认为该SCell激活生效的时间点不得早于
Figure PCTCN2020080271-appb-000001
并且不得晚于
Figure PCTCN2020080271-appb-000002
其中:
k1为从UE接收该PDSCH到发送针对该PDSCH的ACK/NACK反馈之间的时间间隔;
Figure PCTCN2020080271-appb-000003
为与用于传输ACK/NACK反馈的PUCCH子载波间隔μ对应的一个子帧的时隙个数;
T activation_time为SCell激活时延;
T CSI_reporting为CSI(Channel state information,信道状态信息)上报时延,包括UE获取第一个可用的下行CSI参考资源的时间,UE准备CSI上报的处理时间和UE获得 第一个可用的CSI上报资源的时间。
如果UE在时隙n收到MAC CE指示UE去激活某个SCell,则UE认为该SCell去激活生效的时间点不得晚于时间点n+k 1+3ms,其中:k1为从UE接收该PDSCH到发送针对该PDSCH的ACK/NACK反馈之间的时间间隔。
MAC CE指示的TCI state切换时间
如果UE在时隙n收到MAC CE指示激活一个TCI state,则UE认为该TCI state激活的时间为
Figure PCTCN2020080271-appb-000004
之后的第一个时隙。
其中:
k1为从UE接收该PDSCH到发送针对该PDSCH的ACK/NACK反馈之间的时间间隔;
Figure PCTCN2020080271-appb-000005
为与用于传输ACK/NACK反馈的PUCCH子载波间隔μ对应的一个子帧的时隙个数。
按照TS38.133规定,UE能够在该MAC CE指示的目标TCI state上接收PDCCH的时间不能晚于时隙n+T HARQ+3ms+TOk*(T first-SSB+T SSB-proc)。UE能够在原来的TCI state上接收PDCCH直到时隙n+T HARQ+3ms+TOk*(T first-SSB)。
其中:
T HARQ为从UE接收PDSCH到发送针对该PDSCH的ACK/NACK反馈之间的时间间隔;
如果目标TCI state为已知的,则TOk为0;否则,TOk为1;
T first-SSB为UE解码得到MAC CE到第一次SSB传输之间的时间间隔;
T SSB-proc为UE处理SSB的时间。
针对一些传输时延大的通信,可以考虑关闭上行/下行HARQ进程的HARQ反馈功能以降低数据传输时延。例如,NTN系统中终端与卫星之间的无线信号传输时延较大的特性,在3GPP对NTN标准化过程中已经同意可以关闭上行/下行HARQ进程的HARQ反馈功能以降低数据传输时延,并且RAN2小组已经同意可以基于UE或者基于HARQ进程进行关闭HARQ反馈功能的配置,RAN1小组正在讨论是否要支持基于PDCCH来进行开启/关闭HARQ反馈功能的动态指示。
从上述MAC CE指示的SCell激活去激活的生效时间和MAC CE指示的TCI state 切换时间可以看出,都是由UE针对携带该MAC CE的PDSCH的ACK反馈时间点推算得到。在NTN中,如果使用关闭HARQ反馈功能的PDSCH传输这些MAC CE,由于不存在针对该PDSCH传输的ACK反馈的时间点,原来的MAC CE生效时间确定方法不再适用。针对这种情况,如何确定MAC CE指示的SCell激活去激活的生效时间和MAC CE指示的TCI state切换时间,明确UE的行为,是需要从标准层面解决的问题。
基于上述说明,本申请实施例提出了一种生效时间的确定方法。图2为本申请实施例提供的生效时间的确定方法一的示意性流程图,如图2所示,该方法包括:
S202,终端接收物理下行共享信道PDSCH,其中,该PDSCH中混合自动重复请求HARQ反馈功能关闭,该PDSCH携带下行媒质接入控制控制单元MAC CE。
S204,终端确定下行MAC CE所指示的下行配置的生效时间。
通过上述步骤,终端在关闭PDSCH的HARQ反馈功能的情况下,确定MAC CE指示的下行配置的生效时间,规范了终端的行为,为在关闭PDSCH的HARQ反馈功能的情况下,如何确定MAC CE指示的下行配置的生效时间,提供了一个标准,进而解决了相关技术中无相关标准的问题。
需要说明的是,该方法可以应用于非地面通信网络NTN系统中。即在NTN系统中终端与卫星之间的无线信号传输时延较大,在3GPP对NTN标准化过程中可以关闭上行/下行HARQ进程的HARQ反馈功能以降低数据传输时延。通过NTN中UE确定下行MAC CE所指示的下行配置生效时间的方法,能够在使用关闭HARQ反馈功能的PDSCH传输下行MAC CE的情况下,通过确定该MAC CE的生效时间点,规范了UE的行为,实现了NTN的标准化。
另外,该方法中的终端可以是智能终端,例如,可以是一些智能手机、智能汽车、无人机、机器人等智能终端。还可以是一些可穿戴设备,例如,智能手表,智能手环,智能眼镜等。
作为一种可选的实施例,该下行配置可以包括多种,例如,可以包括以下至少之一:激活辅服务小区SCell,去激活SCell,激活传输配置指示TCI状态。上述下行配置仅为一种列举,其它通过MAC CE指示的下行配置也属于本申请的一部分。
作为一种可选的实施例,终端确定下行MAC CE所指示的下行配置的生效时间时,可以依据具体的场景,采用不同的处理方式,例如,终端可以使用以下方式至少之一确定下行MAC CE所指示的下行配置的生效时间:终端根据物理下行控制信道PDCCH中指示的k1值确定下行MAC CE所指示的下行配置的生效时间;终端通过协议预定义的k1值确定下行MAC CE所指示的下行配置的生效时间;终端通过网络设备广播的k1值确定下行MAC CE所指示的下行配置的生效时间;终端通过网络设备基于终端的能力配置的k1值确定下行MAC CE所指示的下行配置的生效时间;其中,该k1值包括指示终端解码PDSCH所能使用的时间长度,即该终端需要在k1的时间长度内完成对PDSCH的解码。针对上述所给出的方式,下面以PDCCH指示的方式,以及基于UE能力配置的方式进行举例说明。
在终端根据PDCCH中指示的k1值确定下行MAC CE所指示的下行配置的生效时间的情况下,可以根据所述PDCCH中PDSCH的HARQ反馈时间指示PDSCH-to-HARQ_feedback timing indicator域指示的所述k1值确定所述生效时间。该PDCCH可以通过一个指示域来指示该k1值,其中,该指示域可以采用一个现有的指示域,也可以是一个全新的指示域。例如,PDCCH可以通过PDSCH的HARQ反馈时间指示PDSCH-to-HARQ_feedback timing indicator域指示k1值,即通过一个新的指示域来实现对k1值的指示。
在终端通过网络设备基于终端的能力配置的k1值确定下行MAC CE所指示的下行配置的生效时间的情况下,终端向网络设备进行能力上报;终端获取k1值,其中,k1值由网络设备基于上报的能力确定。
需要指出的是,终端的能力可以包括多种,例如,可以包括:终端解码PDSCH的最长时间。
另外,在终端获取k1值时,终端也可以通过多种方式获取该k1值,例如,终端可以通过以下方式至少之一获取k1值:终端通过无线资源控制RRC信令获取k1值;终端通过MAC CE指示的方式获取k1值。当然,终端也可以通过其它网络信令来将获取网络设备基于UE的能力确定的k1值,在此不进行一一举例。
作为一种实施例,终端确定下行MAC CE所指示的下行配置的生效时间还可以包括:在PDSCH为下行绑定bunding传输的情况下,根据终端接收bunding传输的最后一次重复传输的时间点确定该生效时间。即针对bunding传输的情况下,下行配置的生效时间中的开始时间依据接收bunding传输的最后一次重复传输的时间点来确定。
本申请实施例还提出了一种生效时间的确定方法,图3为本申请实施例提供的生效时间的确定方法二的示意性流程图,如图3所示,该方法包括:
S302,网络设备确定物理下行共享信道PDSCH中混合自动重复请求HARQ反馈功能关闭,其中,该PDSCH携带下行媒质接入控制控制单元MAC CE;
S304,网络设备向终端发送PDSCH,其中,该终端在PDSCH中的HARQ反馈功能关闭的情况下,确定下行MAC CE所指示的下行配置的生效时间。
通过上述步骤,网络设备在确定PDSCH中的HARQ反馈功能关闭的情况下,向终端发送PDSCH,实现终端在关闭PDSCH的HARQ反馈功能的情况下,确定MAC CE指示的下行配置的生效时间,为在关闭PDSCH的HARQ反馈功能的情况下,如何确定MAC CE指示的下行配置的生效时间,提供了一个标准,进而解决了相关技术中无相关标准的问题。
作为一种实施例,对应于上述图2所示的终端侧的生效时间的确定方法一,网络侧的设备对应执行以下至少之一,即网络设备所对应的生效时间的确定方法二,还可以包括以下至少之一:网络设备向终端发送物理下行控制信道PDCCH,其中,PDCCH中指示有k1值;网络设备向终端广播k1值;网络设备基于终端的能力确定k1值,并将确定的k1值通过网络消息发送给终端;其中,k1值用于终端确定下行MAC CE所指示的下行配置的生效时间,k1值包括指示终端解码PDSCH所能使用的时间长度。
对应地,在网络设备向终端发送物理下行控制信道PDCCH的情况下,所述网络设备通过PDCCH中PDSCH的HARQ反馈时间指示PDSCH-to-HARQ_feedback timing indicator域指示k1值。
对应地,终端的能力可以包括:终端解码PDSCH的最长时间。即网络设备基于终端解码PDSCH所需要的最长时间作为终端的能力,来确定下行配置的生效时间。
对应地,网络设备可以通过多种方式将依据终端的能力确定的k1值发送给终端,例如,网络设备可以通过RRC信令的方式告之终端,也可以通过MAC CE指示的方式告之终端,当然也可以采用其它网络信令来实现。
结合上述实施例及优选实施例,下面对本申请所提供的实施方式进行说明。
