Description

通信方法、通信装置、通信设备及存储介质 技术领域
本公开涉及但不限于通信技术领域，尤其涉及一种通信方法、通信装置、通信设备及存储介质。
背景技术
目前，新一代的增强现实(Augmented Reality，AR)或者虚拟现实(Virtual Reality，VR)等新型互联网应用的不断涌现对于无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足应用的需求。当下，蜂窝移动通信技术正在处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求，如增强移动带宽(enhanced Mobile Broad Band，eMBB)业务类型主要的要求侧重在大带宽以及高速率等方面；超可靠性延迟通信(Ultra Reliable Low Latency Communication，URLLC)业务类型主要的要求侧重在高可靠性以及低时延等方面；海量机器类通信(massive Machine Type Communication，mMTC)业务类型主要的要求侧重在大数据的方面。因此新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
在无线通信技术的研究中，卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信系统由卫星部分和地面部分组成。卫星通信的特点是：通信范围大；只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信；不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充，可以有以下的好处：
延伸覆盖：对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区，如海洋，沙漠，偏远山区等，可以通过卫星通信来解决通信的问题。
应急通信：在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下，使用卫星通信可以快速的建立通信连接。
提供行业应用：比如对于长距离传输的时延敏感业务，可以通过卫星通信的方式来降低业务传输的时延。
可以预见，在未来的无线通信系统中，卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合，真正的实现万物智联。然而，由于卫星的高速移动，无法有效实现在卫星通信场景下数据交互的可靠性。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通 信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为新一代无线接入网(New Generation-Radio Access Network，NG-RAN)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体接入控制(Medium Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的车对车(vehicle to vehicle，V2V)通信、车对路边设备(vehicle to Infrastructure，V2I)通信和车对人(vehicle to pedestrian，V2P)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。

若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了更好地理解本公开任意实施例所述描述的技术方案，首先，对卫星通信场景等相关内容进行部分说明：
在卫星通信的场景下，由于发送端与接收端存在较长的信号传输距离，导致数据传输有较大的时间，该较大的时间为传输时延；对于传输(包括上下行传输)引入了时间偏移量来补偿该传输时延。
在一个实施例中，基站侧上行传输和下行传输定时对齐。如图2所示：基站(gNB)的上行传输(gNB UL)和下行传输(gNB DL)定时对齐，也就是图2中gNB UL和gNB DL中标为n的帧是对齐的；且参见图2，gNB UL与用户设备的下行传输(UE DL)存在传输时延(Delay)；UE的上行传输定时提前(Time Advance，TA)需要考虑到UE到卫星的传输时延，以使得不同的UE的上行传输能够在预定的时间范围内达到gNB。
在另一个实施例中，基站侧上行传输和下行传输定时不对齐。如图3所示：gNB的上行传输和下行传输不对齐，也就是图3中gNB UL和gNB DL中标为n的帧是不对齐的，在时域上存在偏移(gNB DL-UL frame timing shift)；gNB的下行传输(gNB DL)与UE的下行传输(UE DL)存在传输时延(Delay)；同样的UE的上行传输定时提前(Time Advance，TA)需要考虑到终端到卫星的传输时延，以使得不同的UE的上行传输能够在预定的时间范围内达到gNB。在本示例中，考虑定时提前时会考虑到gNB的上行传输与下行传输的时域上的定时偏移(gNB DL-UL frame timing shift)。
在一个实施例中，时间偏移量可以应用但不限于应用在以下至少之一的传输中：下行控制信息(Downlink Control Information，DCI)调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输，混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息的传输以及媒体访问控制(Media Access Control，MAC)控制单元(Control Element，CE)。在一个实施例中，时间偏移量包括：定时偏移量(Koffset)。例如，定时偏移量应用到HARQ反馈信息的传输中，若UE接收PDSCH的最后一个时隙为时隙n，则UE在时隙n+K 1+Koffset中传输包括对应的HARQ-ACK信息的物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)；其中，K 1为时隙数目。又如，定时偏移量应用到DCI的PUSCH中，若UE在时隙n接收到调度PUSCH传输的DCI，且DCI中指示时隙偏移为K 2；则UE在时隙
Figure PCTCN2021120382-appb-000001
中传输PUSCH；其中，μ PUSCH和μ PDCCH分别是PUSCH和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的子载波间隔配置。
在一个实施例中，Koffset的取值取决于UE到网络设备(例如基站)的传输时延。对于卫星通信的长江，不同卫星若在不同的高度的空间轨道上，则Koffset的取值不同。
在卫星通信的场景下，不同的场景下用的时间偏移量的范围可能是不一样的。在一个实施例中，时间偏移量的范围取决于轨道信息以及参考点(reference point)的位置信息。在一个实施例中，时间偏移量的范围大于等于0且小于等于450ms。
在一个实施例中，一个时间偏移量的范围支持所有卫星通信的场景。在本实施例中，该种时间偏移量的范围指示的粒度会比较大，造成额外的信令开销。
在一个实施例中，不同的时间偏移量的范围支持不同的卫星通信场景。在本实施例中，需要定义不同的应用场景以及应用场景对应的值范围(value range)。
如图4所示，本公开实施例提供一种通信方法，由NTN的网络设备执行，包括：
步骤S41：发送第一信息，第一信息包括：定时范围信息及第一指示信息；其中，定时范围信息用于指示时间偏移量的定时范围；第一指示信息，用于指示从定时范围中确定的时间偏移量。
本公开实施例所提供的方法应用在NTN中，该NTN包括但不限于：利用卫星作为中继而进行通信的网络。
本公开实施例所提供的方法可以由NTN的网络设备执行；该NTN的网络设备包括：接入网设备或者核心网设备。
在一个实施例中，接入网设备可以是但不限于是各种类型的基站；例如可以是2G基站、3G基站、4G基站、5G基站或者其它演进型基站。
在一个实施例中，核心网设备可以是各种物理实体或者逻辑实体，例如可以是移动性管理实体或者服务网关等。当通信方法由核心网设备执行时，是核心网设备将第一信息发送给基站，再由基站转发第一信息给UE。
在一个实施例中，时间偏移量包括：定时偏移量(Koffset)。
本公开实施例提供的一种通信方法，由NTN的网络设备执行，可包括：向UE发送第一信息，其中，第一信息包括：定时范围信息及第一指示信息；其中，定时范围信息指示Koffset的定时范围；第一指示信息，指示从定时范围中确定的Koffset。
在一个实施例中，Koffset可以用于补偿UE的上下行的定时偏差。
在一个实施例中，Koffset大于或等于定时提前。例如，定时提前为10毫秒(ms)，则Koffset为12ms。
如此，可以通过时间偏移量补充NTN的网络设备(例如基站)与UE之间传输的传输时延，从而提高NTN的网络设备与UE之间数据传输的可靠性。
在一个实施例中，定时范围信息包括：第一定时范围或第二定时范围。
在一个实施例中，第一定时范围可认为是统一定时范围(unified value range)。示例性的，基站给小区内部分UE或者全部UE发送统一定时范围0至1000ms或者0至500ms。示例性的，统一定时范围支持卫星通信的所有应用场景。
在另一个实施例中，第二定时范围可认为是通信协议中规定的预定个数的定时范围的其中之一。示例性的，如下表所示，第二定时范围可以是0-100ms、101-200ms、201-300ms、301至400ms、401至500ms。
序号 第二定时范围
1 0-100ms
2 101-200ms
3 201-300ms
4 301-400ms
5 401-500ms
表1
这里，预定个数的第二定时范围可以预先存储在基站中；基站发送第一信息时，可以携带其中一个第二定时范围发送给UE。这里，预定个数可以为大于1的个数。这里，预定个数的第二定时范 围的范围可以不是表1所示的范围；例如，也可以是0-200ms、201-400ms、或者401-600ms等。
可以理解的是，上述表1中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中所有元素必须根据表格所示的同时存在。其中每一个元素的值，是不依赖表1中任何其它元素值。因此本领域技术人员可以理解，该表1中的每一个元素的取值都是一个独立的实施例。
在一个实施例中，第一定时范围可划分为一个或多个第二定时范围。例如，第一定时范围为0至500ms；可以将第一定时范围划分为5个第二定时范围，分别为0-100ms、101-200ms、201-300ms、301至400ms、401至500ms。
在另一个实施例中，第一定时范围的范围大于或等于第二定时范围的范围。例如，第一定时范围为0至500ms；第二定时范围为301-400ms。
在又一个实施例中，第一定时范围与第二定时范围是没有特定关系的两个范围。例如，第一定时范围为0至200ms；第二定时范围为150ms至250ms。
在一个实施例中，第一指示信息可以为第一预定数量比特的信息。这里，第一预定数量比特可以为大于或等于1的比特。
示例性的，通信协议预先定义第一指示信息与Koffset的定时范围的Koffset的对应关系。例如Koffset的定时范围为0-100ms。如第一指示信息可以通过4个比特指示：第一指示信息为“0000”时，指示Koffset为0ms；第一指示信息为“0001”时，指示Koffset为10ms；第一指示信息为“0010”时，指示Koffset为20ms；等等。又如第一指示信息可以通过8个比特指示：第一指示信息为“00000000”时，指示Koffset为0ms；第一指示信息为“00000001”时，指示Koffset为1ms；第一指示信息为“00000010”时，指示Koffset为2ms；第一指示信息为“00000011”时，指示Koffset为3ms；等等。
在本公开实施例中，可以通过NTN的网络设备告知UE卫星通信场景下的定时范围及第一指示信息，使得UE可以基于第一指示信息确定出合适当前卫星通信场景下的时间偏移量；从而提高不同卫星通信场景下确定的时间偏移量的精准性，进而提高NTN的网络设备与UE之间传输的可靠性。
本公开实施例提供一种通信方法，由NTN的网络设备执行，包括：发送携带第一信息的高层信令或者物理层信令。
在一个实施例中，高层信令包括：无线资源控制(Radio Resource Control，RRC)信令或者媒体访问控制层(Media Access Control，MAC)控制单元(Control Element，CE)信令。
在一个实施例中，物理层信令包括：下行控制信息(Downlink Control Information，DCI)信令。
在另一个实施例中，NTN的网络设备也可以通过现有的系统消息或者专用的系统消息发送第一信息。
在本公开实施例中，NTN的网络设备可以通过高层信令、物理层信令及系统消息等携带第一信息发送，从而可以提高高层信令、物理层信令或系统消息的利用效率，以及可以节省信令的开销。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也 可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图5所示，本公开实施例提供一种通信方法，由NTN的网络设备执行，可包括：
步骤S51：发送第一信息，其中，第一信息包括：指示参考定时时间的参考定时信息、第一定时范围及第一指示信息；其中，参考定时时间与第一指示信息，用于指示从第一定时范围中确定的时间偏移量。
在本公开的一些实施例中，第一指示信息为步骤S41中的第一指示信息；第一定时范围为步骤S41中的第一定时范围；时间偏移量为步骤S41中的时间偏移量。
本公开实施例提供一种通信方法，由NTN的网络设备执行，可包括：基于卫星的星历信息，确定参考定时信息。
这里，卫星的星历信息也可以是指卫星的轨道信息；卫星的星历信息可以指示不同时间卫星的轨道状态。如此，NTN的网络设备可以通过卫星的信息或者卫星的轨道信息，确定卫星所处的高度范围，进而根据高度范围确定参考定时信息。这里，卫星的高度范围的高度与参考定时信息指示的参考定时时间成正相关。
如此，本公开实施例可以根据卫星实际运行的轨迹，确定出准确的参考定时时间，从而确定出准确的时间偏移量。
在一个实施例中，参考定时时间，包括：一个或多个时隙。例如，若一个时隙为1ms；若参考定时时间包括1个时隙，则参考定时时间为1ms；若参考定时时间包括10个时隙，则参考定时时间为10ms。
在另一个实施例中，参考定时时间，包括：预定子载波间隙(Subcarrier Spacing，SCS)对应的一个或多个时隙。这里，预定子载波间隙可以是指任意一个SCS；例如预定SCS可以为15KHZ、30KHZ、或者240KHZ等。示例性的，若预定SCS为15KHZ，则1个符号为66.67微妙(us)；1个时隙包括14个符号，则1个时隙大约1ms。若参考定时时间包括：预定SCS对应的一个时隙，则参考定时时间为1ms；若参考定时时间包括：预定SCS对应的12个时隙，则参考定时时间为12ms。
在又一个实施例中，参考定时时间，也可以包括：预定SCS对应的多个符号。
在一个实施例中，参考定时时间与第一指示信息指示的数值的乘积，用于指示从第一定时范围中确定时间偏移量。
示例性的，若基站发送给UE的第一定时范围为0至1000ms、第一指示信息为“0001”、以及参考定时信息指示的参考定时时间为10ms；第一指示信息指示的数值为1以及参考定时时间为10ms，则确定第一指示信息与参考定时时间指示第一定时范围0至1000ms中的时间偏移量为10ms。
示例性的，若基站发送给UE的第一定时范围为0至1000ms、第一指示信息为“0011”、以及参考定时信息指示的参考定时时间为10ms；第一指示信息指示的数值为3以及参考定时时间为10ms，则确定第一指示信息与参考定时时间指示第一定时范围0至1000ms中的时间偏移量为30ms。
示例性的，若基站发送给UE的第一定时范围为0至1000ms、第一指示信息为“0011”、以及 参考定时信息指示的参考定时时间为100ms；第一指示信息指示的数值为3以及参考定时时间为100ms，则确定第一指示信息与参考定时时间指示第一定时范围0至1000ms中的时间偏移量为300ms。
本公开实施例中，可以通过NTN的网络设备给UE发送第一定时范围支持卫星通信的所有应用场景，以及给UE发送参考定时信息以及第一指示信息；如此可以使得UE通过不同的参考定时信息以及第一指示信息实现不同粒度的第一定时范围中时间偏移量的指示。如此可以使得UE实现卫星通信的各种应用场景通过一个统一的定时范围确定出精确的时间偏移量；进而提高该些应用场景下NTN的网络设备与UE之间传输的可靠性。
并且，对于第一定时范围的范围相对较大时，可以通过配置较大的参考定时时间，使得即便采用比特数量相对较少的第一指示信息，也能指示出准确的NTN的网络设备与UE传输的时间偏移量。如此，可以节省第一指示信息的比特数，减少信令的开销。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图6所示，本公开实施例提供一种通信方法，由NTN的网络设备执行，可包括：
步骤S61：发送第一信息；其中，第一信息包括：第二定时范围及第一指示信息，或者指示第二定时范围的第二指示信息及第一指示信息，或者星历信息及第一指示信息；其中，星历信息，用于确定时间偏移量的第二定时范围；其中，第一指示信息，用于指示从第二定时范围中确定的时间偏移量。
在本公开的一些实施例中，第一指示信息为步骤S41中的第一指示信息；第二定时范围为步骤S41中的第二定时范围；时间偏移量为步骤S41中的时间偏移量。
在一个实施例中，第二指示信息为第二预定比特数量的信息。这里，第二预定数量比特可以为大于或等于1的比特。
示例性的，通信协议预先定义第二指示信息与第二定时范围的对应关系。例如第二指示信息为“001”时，指示第二定时范围为0-100ms；第二指示信息为“010”时，指示第二定时范围为101-200ms；第二指示信息为“011”时，指示第二定时范围为201-300；第二指示信息为“0100”时，指示第二定时范围为301-400ms；第二指示信息为“0101”时，指示第二定时范围为401-500ms；等等。如此，若UE接收到第二指示信息后，可以基于第二指示信息确定出第二定时范围。
在一个实施例中，卫星的星历信息也可以是指卫星的轨道信息；卫星的星历信息或者轨道信息，可用于确定卫星所处的高度范围。这里，卫星的高度为范围的高度与第二定时范围的上限值及下限值的大小呈正相关。例如，若卫星的高度低于600千米(km)时，第二定时范围为0-40ms；若卫星的高度为600-12000km时，第二定时范围为40-600ms；等等。如此，若UE接收到星历信息后，可以基于星历信息确定出第二定时范围。
在一个实施例中，星历信息也可以通过系统消息发送给UE。如此，本实施例可以通过系统消息 携带星历信息发送，可以减少信令开销。
在一个实施例中，通信协议预先定义第一指示信息与第二定时范围的时间偏移量的对应关系。如此，可以通过第一指示信息指示第二定时范围中的时间偏移量。
示例性的，基站向UE发送的第二定时范围为0-100ms、及第一指示信息为“0001”；第一指示信息“0001”指示的是10，则确定第一指示信息指示第二定时范围0至100ms中的时间偏移量为10ms。
示例性的，基站向UE发送的第二定时范围为0-100ms、及第一指示信息为“0101”；第一指示信息“0101”指示的是50，则确定第一指示信息指示第二定时范围0至100ms中的时间偏移量为50ms。
示例性的，基站向UE发送的第二定时范围为101-200ms、及第一指示信息为“0101”；第一指示信息“0101”指示的是50，则确定第一指示信息指示第二定时范围101至201ms中的时间偏移量为150ms。
示例性的，基站向UE发送的第二定时范围为0-100ms、及第一指示信息为“00000001”；第一指示信息“00000001”指示的是1，则确定第一指示信息指示第二定时范围0至100ms中的时间偏移量为1ms。
