为了使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开作进一步地详细描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本公开保护的范围。
以下对本公开实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
(1)本公开实施例中,名词“网络”和“系统”经常交替使用,但本领域的技术人员可以理解其含义。
(2)本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
(3)“和/或”,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。字符“/”一般表示前后关联对象是一种“或”的关系。
(4)本公开的一些实施例中,使用“CG/SPS配置”表示CG配置或半持续调度(Semi-Persist Scheduling,SPS)配置。本公开实施例中,一个免调度的半持续传输配置可以是CG配置或SPS配置。CG配置用于上行传输,SPS配置用于下行传输。对于一个CG配置,可以使用一个索引(index)唯一标识。对于一个SPS配置,可以使用一个索引(index)唯一标识。
一个CG配置内可以包括一个或多个参数(或称为CG配置参数,或动态参数),举例来说,可以包括CG传输周期,时频资源,调制编码机制(Modulation Code Scheme,MCS),时域偏移,频域偏移等。
一个SPS配置内可以包括一个或多个参数(或称为SPS配置参数,或动态参数),举例来说,可以包括SPS传输周期,时频资源,MCS,时域偏移,频域偏移等。
目前对于低时延和高可靠性的传输要求,CG技术可以有效减低传输时延,但仍存在较大可提升空间。
对于XR业务的下行数据流,可以采用截断高斯分布表示数据包的大小和抖动(jitter),对于AR的上行单视频流的建模方式与下行单视频流数据包大小和抖动的建模方式一致。以图1a和图1b为例,其中图1a为XR数据包业务分布示意图,图1b为XR数据包抖动
分布示意图。其中,横坐标为数据包的大小和抖动大小,纵坐标为概率统计。可以看出,相比于超高可靠和超低时延通信(ultra-Reliable Low-Latency Communications,uRLLC)的典型的小数据包传输,XR业务的数据包大小和到达时间间隔都表现为不同的特性,因而需要更加动态的调整数据传输相关参数用来匹配XR的数据包大小的变化和抖动所带来的影响。
目前上行免调度传输方案分为Type 1和Type 2两种:
在Type 1中,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的传输参数是通过无线资源控制(Radio Resource Configuration,RRC)配置的,根据配置信息可以确定周期性的PUSCH传输机会。当终端上行有新数据到达时,可以在最近的传输机会直接进行PUSCH传输。
在Type 2中,PUSCH的传输参数是通过RRC和物理下行控制信道(Physical Downlink Control Channel,PDCCH)共同配置的,RRC配置周期和偏移、数据速率相关参数(比如MCS)、时频资源等参数,PDCCH激活信令通知配置的Type2激活并同时指示调度信息。只有在收到激活信令之后,终端才能使用对应的PUSCH资源进行上行免调度传输。如果想释放Type2PUSCH资源,可以通过发送PDCCH去激活信令来实现。
对于XR业务,数据包大小、网络拥塞情况不同而导致业务源数据包到达会有不同程度的时延抖动(Jitter),且该时延抖动具有一定的随机性。目前CG技术和SPS技术中,诸如MCS等参数在低时延、高可靠性、高数据传输速率等动态参数的更新,是通过RRC信令配置的,使得XR业务不能适应其数据包大小的变化。
为了克服抖动导致的包达到随机的问题,一种可能的解决方案是配置多个免调度的半持续传输配置(以下简称为CG/SPS配置)。
配置多个CG/SPS配置,对于XR业务并不适用,主要在于:
(1)多个CG/SPS配置支持XR业务的包抖动和包大小可变问题,可能会存在传输配置不够用的情况,比如:
为匹配XR业务包抖动变化范围[-4ms,+4ms],结合对于时延的需求,考虑配置多个CG/SPS配置来匹配可能的包抖动变化,如图2所示,图中不同填充的方格表示不同的数据包。例如,可以考虑每个时隙(slot)配置一个CG/SPS配置;为进一步匹配业务的变化,在每个包抖动的配置下,调整CG/SPS配置的MCS或是时频资源,例如,再配置3个CG/SPS配置,此时,总共需要的最大CG/SPS配置的个数为8*3=24。而CG/SPS最大支持的配置个数为12个,包括Type1的CG配置在内;进一步的,CG/SPS配置的索引(index)由混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)的4比特指示,此时不能支持
足够多的CG/SPS配置。
(2)多个CG/SPS配置的激活/去激活的时延和信令开销问题。
现有协议中,对于CG/SPS的激活,一个下行控制信息(Downlink Control Indication,DCI)只能激活一个CG/SPS配置,如果需要激活多个CG/SPS配置,则需要多个DCI指示,导致需要更多的时延和信令开销。
如图3所示,当DCI携带激活信令时,一个DCI只能同时激活一个CG/SPS配置,当需要激活多个CG/SPS传播配置时,需要发送多个DCI;如果每个时隙发送一个激活DCI,则多个CG/SPS配置的激活时间较长;如果每个时隙发送多个激活DCI,则多个CG/SPS配置的激活时间可以减少一部分,但是在一个时隙内对用于激活CG/SPS配置的多个DCI进行盲检,会在一定程度上增加终端的开销。
(3)重激活CG/SPS配置的灵活性问题。
重激活CG/SPS配置,仅仅包括DCI指示的参数部分的重激活,对于周期、MCS、时频资源等参数无法通过DCI重激活,而动态调整诸如周期、MCS、时频资源等参数,对于匹配XR业务的包大小和包抖动,又是非常必要的。
对于一个半持续传输的CG/SPS配置,由于每个XR业务的数据传输周期内数据包大小都是变化的,并且大小差异较大,在一个CG/SPS配置的时间传输范围内,很难匹配这种动态变化,从而使得在一个CG/SPS配置下,CG/SPS的参数动态可调以匹配XR业务的数据包大小动态变化,就变得更加迫切。
基于以上一个或多个问题,本公开实施例提供了一种通信方法及其装置。
本公开的一些实施例中,通过显示指示方式和隐式指示方式相结合的方法,改变CG/SPS配置下的动态参数,从而动态调整数据传输,可以使得数据传输更加匹配XR业务的可变的数据包大小,降低终端/业务的冲突和碰撞。
其中,所述改变CG/SPS配置下的动态参数,是指CG/SPS索引(index)不变的情况下,调整CG/SPS配置的内部参数,例如,数据传输速率相关的参数,更具体的,可以包括MCS、时频资源、CG/SPS传输周期等。
本公开的另一些实施例中,通过一个信令(比如DCI)实现对一个或多个CG/SPS配置的激活以及对另外一个或多个CG/SPS配置的去激活,以节省信令开销。

在一种可能的实现方式中,在上述S501中,终端接收网络设备在物理下行控制信道(Physical Downlink Control Channel,PDCCH)发送的DCI,该DCI中包括所述第一信息,可选的,该DCI可以是激活传输配置(比如CG配置或SPS配置)的DCI,也就是说,第一信息(比如第一传输配置参数)可以通过激活传输配置的DCI发送给终端。在另一种可能的实现方式中,在上述S501中,终端接收网络设备在物理下行共享信道(Physical Downlink Shared Channel,PDSCH)发送的所述第一信息,也就是说,第一信息(比如第一传输配置参数)可以通过PDSCH发送给终端。在另一种可能的实现方式中,在上述S501中,终端接收网络设备发送的下行参考信号,所述下行参考信号携带所述第一信息,也就是说,第一信息(比如第一传输配置参数)可以通过下行参考信号发送给终端。可选的,所述参考信号可以包括信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)、定时参考信号(Timing Reference Signal,TRS)、同步信号块(Synchronization Signal Block,SSB)、定位参考信号等,本公开实施例对此不做限制。
以通过DCI发送上述第一CG配置参数为例,通过DCI,网络设备可以向终端指示CG传输位置上的CG配置参数(即动态参数)。比如,网络设备可以在配置的CG的传输位置之前,发送DCI,来指示本次CG传输位置上的CG的动态参数(比如上述的第一CG
配置参数)。可选的,如果终端在CG传输的位置上没有检测到该DCI,则采用初始的CG传输位置上的CG动态参数进行上行数据传输。可选的,该DCI可以携带CG配置的索引。
以通过DCI发送上述第一SPS配置参数为例,通过DCI,网络设备可以向终端指示SPS传输位置上的SPS配置参数(即动态参数)。比如,网络设备可以在配置的SPS的传输位置之前,发送DCI,来指示本次SPS传输位置上的SPS的动态参数(比如上述的第一SPS配置参数)。可选的,如果终端在SPS传输的位置上没有检测到该DCI,则采用初始的SPS传输位置上的SPS动态参数进行上行数据传输。可选的,该DCI可以携带SPS配置的索引。
在一种可能的实现方式中,上述N个第一传输配置参数中的每个第一传输配置参数与第二传输配置参数之间的关联关系,可以是预先配置的或预先定义的。比如说,可以预先在终端和网络设备中配置N个第一传输配置参数中的每个第一传输配置参数与第二传输配置参数之间的关联关系;也可以在协议中定义N个第一传输配置参数中的每个第一传输配置参数与第二传输配置参数之间的关联关系。
可选的,上述第一传输配置参数与第二传输配置参数之间的关联关系,可以是通过RRC信令置的。
通过上述实现方式,可以使得网络设备根据预先配置或预先定义的关联关系,并进一步根据业务特性需求,选择与当前业务需求匹配的第一传输配置参数,并通过第一信息发送给终端,以使得网络设备与终端之间的数据传输与当前业务需求相适配。
在另一种可能的实现方式中,上述N个第一传输配置参数中的每个第一传输配置参数与第二传输配置参数之间的关联关系,是终端上报给网络设备的。示例性的,所述第一信息包括一个第一传输配置参数,所述一个第一传输配置参数是所述终端上报给所述网络设备的M个第一传输配置参数中的一个,所述M为大于或等于N的整数。示例性的,终端接收网络设备发送的第一信息之前,向所述网络设备发送M个第一传输配置参数,以及所述M个第一传输配置参数中每个第一传输配置参数关联的至少一个第二传输配置参数。可选的,该M个第一传输配置参数是终端期望的第一传输配置参数。相应的,网络设备可以从上述M个第一传输配置参数中选择N个(比如根据信道状态等),并发送给该终端,也就是所,网络设备可以确认该N组传输配置参数中的一组或多组,其中一组传输配置参数可以包括一个第一传输配置参数以及与其关联的至少一个第二传输配置参数。
可选的,终端可以根据信道状态确定该终端期望的M个第一传输配置参数,以及所述M个第一传输配置参数中每个第一传输配置参数关联的至少一个第二传输配置参数。可选的,终端可以通过上行信道和下行信道的互易性确定信道状态,比如可以采用以下方式
确定终端期望的传输配置参数(包括第一传输配置参数和第二传输配置参数):
方式1:可以通过下行参考信号获取上行信道的状态,从而估计得到MCS等参数;
方式2:通过DCI调度的PDSCH的MCS参数,获取上行的MCS等参数。
可选的,终端可以通过上行信号向网络设备上报上述参数。可选的,所述上行信号可以包括以下中的至少一项:上行调度请求(Scheduling Request,SR)信号、可以是唤醒信号(Wake-Up Signal,WUS)、随机接入信道(Radom Access Channel,RACH)的前导(preamble)信号、探测参考信号(Sounding Reference Signal,SRS)、物理上行共享信道(Physical Uplink Shared Channel,PUSCH)信号、物理上行控制信道(Physical Uplink Control Channel,PUCCH)信号。可选的,在将上述传输配置参数携带在PUSCH中发送的情况下,可以通过媒体接入控制控制单元(Media Access Control-Control Element,MAC-CE)上报。本公开实施例对此不作限制。
通过上述实现方式,终端可以通过上行信号,实现对传输配置参数的动态上报,从而可以使得网络及时根据终端侧期望的传输配置参数及时通过第一信息更新该终端的传输配置参数,以适应终端对数据传输的需要,或者适应业务特性。
S502:终端根据上述N个第一传输配置参数中的至少一个第一传输配置参数,以及与所述至少一个第一传输配置参数关联的第二传输配置参数,进行第一数据传输。也就是说,终端可以将上述N个第一传输配置参数中的至少一个第一传输配置参数,以及与所述至少一个第一传输配置参数关联的第二传输配置参数,应用于(或用于)第一数据传输。
若所述第一传输配置参数和所述第二传输配置参数为SPS配置参数(具体的,所述第一传输配置参数为第一SPS配置参数,所述第二传输配置参数为第二SPS配置参数),则所述第一数据传输为下行数据传输。在S502中,在网络设备侧,网络设备可以从N个第一SPS配置参数中选择一个目标SPS配置参数(比如根据终端上报的BSR选择,或者根据信道状态等因素选择),并根据选择的目标SPS配置参数以及该目标SPS配置参数关联的第二SPS配置参数关联,基于相应的资源向终端发送数据;在终端侧,终端根据上述N个第一SPS配置参数以及每个第一SPS配置参数关联的第二SPS配置参数,基于相应的资源接收所述网络设备发送的数据。
在一种可能的实现方式中,若第一传输配置参数和第二传输配置参数为CG配置参数(具体的,第一传输配置参数为第一CG配置参数,第二传输参数为第二CG配置参数),则所述第一数据传输为上行数据传输。在S502中,在终端侧,终端从N个第一CG配置参数中选择目标CG配置参数,根据目标CG配置参数获取与所述目标CG配置参数关联的第二CG配置参数,再根据目标CG配置参数以及与目标CG配置参数关联的第二CG
配置参数,向网络设备发送数据。可选的,终端可以根据当前的信道状态、传输块(Transport Block,TB)大小、缓存状态、传输需求等因素,从N个第一CG配置参数中选择目标CG配置参数。可选的,终端可以通过PUSCH向网络设备发送数据。
相应的,在网络设备侧,网络设备可以根据上述N个第一CG配置参数,以及与每个第一CG配置参数关联的第二CG配置参数,基于相应的资源接收终端发送的数据。也就是说,网络设备可以根据N个第一CG配置参数及其关联的第二CG配置参数对应的多个资源,对该多个资源进行预留,在预留的该多个资源上对终端发送的数据进行盲检接收。
可选的,终端可以向网络设备发送缓存状态报告(Buffer Stage Report,BSR)。这样,在网络设备在向终端发送第一信息之前,可以根据终端上报的BSR确定终端的TB大小,从而可以在S502中,根据终端的TB大小,从N个第一CG配置参数中选择一个第一CG配置参数,并根据该第一CG配置参数以及与其关联的第二CG配置参数,接收终端发送的数据,这样,就没有必要对据N个第一CG配置参数及其关联的第二CG配置参数对应的多个资源均进行资源预留,从而可以提高资源利用率。
通过以上流程可以看出,网络设备可以通过第一信息将传输配置(比如CG配置或SPS配置)中的第一传输配置参数发送给终端,使得终端可以根据该第一传输配置参数获得与其关联的至少一个第二传输配置参数,从而将第一传输配置参数以及与其关联的第二传输配置参数应用于第一数据传输,进而可以通过第一信息动态调整传输配置参数,同时还可以节省信令开销。
本公开上述的一些实施例,通过显示指示(即指示第一传输配置参数)结合隐式指示(即根据第一传输配置参数确定与其关联的第二传输配置参数)的方式,以改变CG配置或SPS配置下的动态参数或CG/SPS配置(比如跳过或删除CG/SPS配置),从而调整数据传输速率,使得数据传输更加匹配XR业务的可变的数据包大小的业务特性,降低终端/业务的冲突和碰撞。
在一种可能的实现方式中,在S502之后,所述方法还包括以下步骤:
S503:网络设备向终端发送第二信息。
可选的,所述第一传输为上行传输时,所述第二信息为网络设备对于所述第一数据传输的反馈信息。所述反馈信息可以用于冲突解决。

示例性的,示例性的,网络设备向终端发送的第一信息包括第一CG配置内的第一CG传输配置参数(比如时域偏移)。此种情况下,网络设备可以根据对该终端的数据接收请情况,生成第一指示信息并向终端发送该第一指示信息,以用于指示该第一CG配置下的第一CG传输配置参数(比如时域偏移)及其对应的第二CG配置参数是否可用,比如,如果网络设备根据该第一CG传输配置参数以及与其对应的第二CG传输配置参数所对应的资源,接收到该终端发送的数据,则生成的指示信息的取值为0,表示可用,否则,生成的指示信息的取值为1,表示不可用。反之亦然。
第二指示信息,用于指示所述N个第一CG配置参数中的每个第一CG传输配置参数及其对应的第二CG配置参数是否可用,该N个第一CG配置参数属于同一CG配置。可选的,该第二指示信息为N比特信息,其中每个比特对应上述N个第一传输配置参数中的一个。
示例性的,网络设备向终端发送的第一信息包括第一CG配置内的N个第一CG传输配置参数。此种情况下,网络设备可以根据对该终端的数据接收情况,生成第二指示信息并向终端发送该第二指示信息,以用于指示该第一CG配置下的N个第一CG传输配置参数及其对应的第二CG配置参数是否可用,比如,如果网络设备根据某个第一CG传输配置参数以及与其对应的第二CG传输配置参数所对应的资源,接收到该终端发送的数据,则生成N个比特信息,并将其中与该第一CG传输配置参数对应的比特设置为0,表示对应的第一CG传输配置参数和第二CG传输配置参数可用,其他比特设置为1。反之亦然。
第三指示信息,用于指示一个或多个需要删除或跳过的CG配置,比如该第三指示信息可以是该一个或多个需要删除或跳过的CG配置的索引。可选的,该第三指示信息可以是多个比特指示信息。
示例性的,网络设备可以基于第一数据传输的情况(即对该终端发送的数据的接收情况),确定应用于第一数据传输的一个或多个CG配置所对应的时频资源发生较多的数据传输碰撞情况,因此可以确定跳过或删除其中的一个或多个CG配置,以降低或避免碰撞的发生。例如,网络设备确定第一CG配置和第二CG配置对应的时频资源上发生的碰撞较多,则可以确定删除或跳过其中的一个CG配置(比如删除或跳过第二CG配置)。
其中,跳过一个CG配置,是指在本次第一数据传输过程中,不使用第一CG配置,或不使用第一CG配置下的传输配置参数(可以使用第一CG配置下的初始的传输配置参数,所述初始的传输配置参数可以是指通过RRC信令配置的CG配置参数)。
在一种可能的实现方式中,网络设备发送的第一信息还包括第三信息,所述第三信息用于指示用于所述第一数据传输的传输配置中需要被跳过的一个或多个传输配置。其中,
所述传输配置包括CG配置或SPS配置。相应的,在终端侧,终端可以根据该第三信息,在第一数据传输过程中不使用相应的一个或多个传输配置下的传输配置参数,或者在第一数据传输过程中不使用相应的一个或多个传输配置下的传输配置参数(可以使用该一个或多个传输配置下的初始的传输配置参数,所述初始的传输配置参数可以是指通过RRC信令配置的传输配置参数)。
可选的,在网络侧,网络设备可以根据对该终端发送的数据的接收情况,若确定一个或多个传输配置对应的时频资源上发生较多碰撞,则可以确定在第一数据传输过程中跳过该一个或多个传输配置。
可选的,所述第三信息包括以下中的一项:
第四指示信息,用于指示用于所述第一数据传输的传输配置中与第一时间最近的传输配置需要被跳过。可选的,该第四指示信息可以是1比特信息。可选的,所述第一时间为当前时间。
被跳过的传输配置的索引。
参见图6,为本公开实施例提供的另一种通信方法的流程示意图,如图所示,该流程可以包括以下步骤:
S601:网络设备向终端发送第一信令。
可选的,所述第一信令为DCI。可选的,所述DCI中包括激活指示信息和去激活指示信息,所述激活指示信息用于指示激活至少一个半持续传输的传输配置,所述去激活指示信息用于指示去激活至少一个半持续传输的传输配置。
可选的,所述传输配置包括CG配置或SPS配置。
可选的,网络设备可以根据数据接收情况,确定需要激活和/或去激活的传输配置,从而可以降低多个传输配置下的数据传输的碰撞(尤其是大数据传输)。同时,在一个DCI中携带激活指示和去激活指示,可以更快的激活或去激活多个传输配置,或激活或去激活传输配置下的多个动态参数,从而减少的发生。
可选的,所述DCI为半持续传输的激活信令或半持续传输的去激活信令。
可选的,所述第一信令(比如激活信令)中,可以包括以下至少一项:
至少一个去激活半持续传输的标识;
至少一个激活半持续传输的标识;
至少一个激活半持续传输的标识和去激活半持续传输的标识(此时去激活和激活的半持续传输的标识相同);
激活半持续传输的配置(所述配置同前所述,比如包括时频资源、MCS、RV版本、
传输周期等)。
可选的,所述激活信令,可以包括动态信令。所述动态信令,可以是基于配置的调度无线网络临时标识(Configured Scheduling Radio Network Temporary Identifier,CS-RNTI)加扰的DCI,或者可以是基于小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)加扰的DCI。
可选的,所述DCI的比特域指示上述激活信令中的至少一项。
进一步的,上述流程还可以包括以下步骤:
S602:终端根据该第一信令进行半持续数据传输。
该步骤中,终端可以根据激活指示信息激活相应的至少一个传输配置,并根据所述去激活指示信息去激活相应的至少一个传输配置。
S602中,激活一个传输配置,包括终端将所述激活指示信息激活的至少一个传输配置用于第一数据传输;去激活一个传输配置,包括放弃使用去激活指示信息指示的至少一个传输配置进行数据传输。
示例性的,终端根据接收的激活指示信息,在相同的时域位置上,按照指示的至少一个激活的半持续调度的半持续传输的时域位置,在该时域位置上进行数据传输,并根据接收的去激活指示信息,在相应的时域位置上,不再发送数据或监测数据传输。
通过上述流程可以看出,采用激活信令或去激活信令,同时激活和去激活传输配置,可以降低基于多个传输配置或者传输配置下的多个动态参数进行数据传输时发生的碰撞(尤其是大数据传输),从而可以更快的激活和去激活多个半持续传输的传输配置,或半持续传输配置下的多个动态参数,从而减少冲突的半持续的传输。对于XR业务,采用本公开的上述流程可以适配XR的数据包大小和包到达时间动态可变的特性,并可以节省信令开销。
下面结合几个示例对本公开的上述实施例进行详细描述。
示例一:该示例是上述图5所示流程的一个示例。
