Hence, in the embodiments of the present application, since first configuration information is configured by a network, it is beneficial to achieve the adaptive adjustment of the number of repeated transmissions of a data channel between a network device and a terminal along with the continuous change of the propagation distance between the terminal and a satellite in a non-terrestrial network communication system, and always ensure that the network device and the terminal agree on the number of repeated transmissions of the data channel.
Description
本申请涉及通信技术领域,尤其涉及一种重复传输次数确定方法与装置、终端和网络设备。The present application relates to the field of communication technologies, and in particular, to a method and device, a terminal, and a network device for determining the number of repeated transmissions.
目前,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)正在制定关于非地面网络(non-terrestrial network,NTN)通信的协议标准,其协议标准主要涉及有航天设备(spaceborne vehicle)或者空运设备(airborne vehicle),例如同步地球轨道卫星、近地轨道卫星、高椭圆轨道卫星、高空平台站(high-altitude platform stations,HAPS)等。At present, the 3rd Generation Partnership Project (3GPP) is developing protocol standards for non-terrestrial network (NTN) communications, and the protocol standards mainly involve spaceborne vehicles or airborne equipment. (airborne vehicle), such as geostationary earth orbit satellites, low earth orbit satellites, highly elliptical orbit satellites, high-altitude platform stations (HAPS), etc.
NTN通信系统中的卫星通常会在地面上产生波束(beam,或者称为beam footprint)或者小区。由于该卫星会沿着固定的轨道不断运动,因此位于上述波束或者小区内的终端与该卫星之间的传播距离(或传播时延)会随着该卫星的位置变化而发生变化,从而导致该终端在数据传输时数据信道的重复传输次数需要随着该卫星的位置变化进行相应调整。然而,由于卫星的运行轨迹具有规律性与周期性而导致终端与该卫星之间的传播距离也具有规律性与周期性,因此NTN通信系统中可能不需要通过下行控制信息(downlink control information,DCI)来动态指示数据信道的重复传输次数以缩减DCI的比特大小。在这种情况下,如何确定数据信道的重复传输次数,还需要进一步研究。Satellites in an NTN communication system typically generate beams (or beam footprints) or cells on the ground. Since the satellite will move along a fixed orbit, the propagation distance (or propagation delay) between the terminal located in the beam or cell and the satellite will change with the position of the satellite, resulting in the When the terminal transmits data, the number of repeated transmissions of the data channel needs to be adjusted accordingly as the position of the satellite changes. However, due to the regularity and periodicity of the orbit of the satellite, the propagation distance between the terminal and the satellite is also regular and periodic. Therefore, in the NTN communication system, it may not be necessary to pass downlink control information (DCI). ) to dynamically indicate the number of repeated transmissions of the data channel to reduce the bit size of the DCI. In this case, how to determine the repeated transmission times of the data channel needs further research.

在对本申请实施例提供的重复传输次数确定方法进行详细介绍之前,再对本申请所涉及的相关通信技术进行介绍。Before the method for determining the number of repeated transmissions provided by the embodiments of the present application is introduced in detail, the related communication technologies involved in the present application are introduced.
1、NTN通信系统1. NTN communication system
在NTN通信系统中,卫星通常会在地面上产生一个或多个波束(beam,或者称为beam footprint)或者小区,而一个波束在地面上的形状可以为椭圆形。其中,部分卫星(例如LEO卫星)在地面上产生的波束或者小区也会随着该卫星在其轨道上的运动而在地面上移动;或者,部分卫星(例如LEO卫星或者GEO卫星)在地面上产生的波束或者小区不会随着该卫星在其轨道上的运动而在地面上移动。In the NTN communication system, the satellite usually generates one or more beams (beam, or called beam footprint) or cells on the ground, and the shape of a beam on the ground can be an ellipse. Among them, the beams or cells generated on the ground by some satellites (such as LEO satellites) will also move on the ground with the movement of the satellites in their orbits; or, some satellites (such as LEO satellites or GEO satellites) are on the ground. The resulting beam or cell does not move on the ground as the satellite moves in its orbit.
由于卫星相对于地面的距离非常远(例如,GEO卫星是35786km),因此在同一个波束或者小区的覆盖范围内,不同地理位置的终端(如UE)与卫星之间的传播距离差异较小(即同一个波束/小区的覆盖范围内不同地理位置的终端对应的信号的路损差异较小),进而导致同一个波束/小区的覆盖范围内不同地理位置的终端对应的信号接收质量(包括终端的下行接收质量或者基站的上行接收质量)差异非常小,如图3所示。Since the distance of the satellite relative to the ground is very far (for example, the GEO satellite is 35786km), within the coverage of the same beam or cell, the difference in propagation distance between terminals (such as UE) in different geographical locations and the satellite is small ( That is, the path loss difference of signals corresponding to terminals in different geographical locations within the coverage of the same beam/cell is small), which in turn leads to the signal reception quality (including the terminal) corresponding to terminals in different geographical locations within the coverage of the same beam/cell The difference of the downlink reception quality of the base station or the uplink reception quality of the base station) is very small, as shown in Figure 3.
在图3中的(a)所示的陆地网通信系统中,同一个波束/小区的覆盖范围内具有不同地理位置的终端3201和终端3202。由于网络设备310到终端3201的传播距离与到终端3202的传播距离之间存在较大差异,因此导致终端3201对应的信号接收质量与终端3202对应的信号接收质量之间存在较大差异。而在图3中的(b)所示的NTN通信系统中,同一个波束/小区的覆盖范围内具有不同地理位置的终端3401和终端3402。由于卫星330到地面的距离非常远,因此卫星330到终端3401的传播距离与到终端3402的传播距离之间存在较小差异,从而导致终端3401对应的信号接收质量与终端3402对应的信号接收质量之间存在较小差异。In the land network communication system shown in (a) of FIG. 3 , there are terminals 3201 and 3202 with different geographic locations within the coverage of the same beam/cell. Since the propagation distance from the network device 310 to the terminal 3201 and the propagation distance to the terminal 3202 are quite different, there is a big difference between the signal reception quality corresponding to the terminal 3201 and the signal reception quality corresponding to the terminal 3202 . On the other hand, in the NTN communication system shown in (b) of FIG. 3 , there are terminals 3401 and 3402 with different geographical locations within the coverage of the same beam/cell. Since the distance from the satellite 330 to the ground is very far, there is a small difference between the propagation distance from the satellite 330 to the terminal 3401 and the propagation distance to the terminal 3402, resulting in the signal reception quality corresponding to the terminal 3401 and the signal reception quality corresponding to the terminal 3402 There are minor differences between them.
2、NTN通信系统的地球固定波束(earth-fixedbeam)场景2. Earth-fixed beam scenario of NTN communication system
在NTN通信系统的地球固定波束场景中,虽然卫星会沿着固定的轨道运行,但是部分卫星(例如LEO卫星或者GEO卫星)在地面上产生的波束(beam,或者称为beam footprint)或者小区不会随着该卫星在其轨道上的运动而在地面上移动,如图4所示。卫星410在地面上产生的波束420不会随着卫星410的运动而移动,而是呈现固定位置。In the earth-fixed beam scenario of the NTN communication system, although satellites run along a fixed orbit, the beams (or beam footprints) or cells generated by some satellites (such as LEO satellites or GEO satellites) on the ground do not will move on the ground as the satellite moves in its orbit, as shown in Figure 4. The beam 420 generated on the ground by the satellite 410 does not move with the movement of the satellite 410, but assumes a fixed position.
3、NTN通信系统的架构3. Architecture of NTN communication system
本申请实施例中NTN通信系统的架构主要包括具有透明卫星(transparent satellite)(或称为弯管有效载荷(bent pipe payload))的NTN通信架构(即透明转发模式)和具有再生卫星(regenerative satellite)的NTN通信架构(即再生信号模式),请参阅图5。其中,图5中的(a)示例出具有透明卫星的NTN通信架构,而图5中的(b)示例出具有再生卫星的NTN通信架构。在图5中的(a)中,透明转发模式的卫星510在地面上产生至少一个波束520,并且该至少一个波束520可以在地面上形成一个小区。此时,位于该小区内的终端530可以测量到该小区的所有波束中的一个波束,并通过该波束与卫星510建立通信连接。同理,在图5中的(b)中,再生信号模式的卫星540在地面上产生至少一个波束550,并且该至少一个波束550可以在地面上形成一个小区。此时,位于该小区内的终端560可以测量到该小区的所有波束中的一个波束,并通过该波束与卫星540建立通信连接。The architecture of the NTN communication system in the embodiment of the present application mainly includes an NTN communication architecture (ie, a transparent forwarding mode) with a transparent satellite (or called bent pipe payload) and a regenerative satellite (regenerative satellite). ) of the NTN communication architecture (i.e. regenerative signal mode), see Figure 5. Among them, (a) in FIG. 5 illustrates the NTN communication architecture with transparent satellites, and (b) in FIG. 5 illustrates the NTN communication architecture with regenerative satellites. In (a) of FIG. 5, the satellite 510 in the transparent repeater mode generates at least one beam 520 on the ground, and the at least one beam 520 can form a cell on the ground. At this time, the terminal 530 located in the cell can measure one beam among all the beams in the cell, and establish a communication connection with the satellite 510 through the beam. Similarly, in (b) of FIG. 5 , the satellite 540 regenerating the signal pattern generates at least one beam 550 on the ground, and the at least one beam 550 can form a cell on the ground. At this time, the terminal 560 located in the cell can measure one beam among all the beams of the cell, and establish a communication connection with the satellite 540 through the beam.
4、NTN通信系统中的时间提前量(timing advance,TA)4. Timing advance (TA) in NTN communication system
在NTN通信系统中,由于卫星会沿着固定的轨道不断运动,因此终端与该卫星之间的传播时延(或传播距离)以及该卫星与网络设备(或非地面网络网关)之间的传播时延(或传播距离)会随着该卫星的不断运动而发生快速变化。为了解决传播时延不断变化的问题,在发送上行数据之前,终端需要进行TA的预补偿(即TA调整)。其中,补偿值的一部分可以是终端通过自身所在的位置信息(如通过全球导航卫星系统计算得到)和卫星星历表(satellite ephemeris)计算得到,而补偿值的另一部分可以是终端根据网络指示的公共时间提前量变化速率(common timing advance rate)计算得到。需要说明的是,公共时间提前量与卫星的位置具有关联关系,即公共时间提前量与卫星到终端之间的传播距离存在关联关系。In the NTN communication system, since the satellite moves continuously along a fixed orbit, the propagation delay (or propagation distance) between the terminal and the satellite and the propagation between the satellite and the network device (or non-terrestrial network gateway) The time delay (or propagation distance) changes rapidly with the constant motion of the satellite. In order to solve the problem that the propagation delay is constantly changing, before sending uplink data, the terminal needs to perform TA pre-compensation (ie, TA adjustment). Wherein, a part of the compensation value can be calculated by the terminal through its own location information (for example, calculated by the global navigation satellite system) and satellite ephemeris (satellite ephemeris), and another part of the compensation value can be calculated by the terminal according to the network instruction The common timing advance rate is calculated. It should be noted that the common timing advance has an associated relationship with the position of the satellite, that is, the common timing advance has an associated relationship with the propagation distance from the satellite to the terminal.
5、预配置上行资源(preconfigure uplink resource,PUR)5. Preconfigure uplink resource (PUR)
在目前的NR通信系统中,处于空闲(idle)态或者非激活态(inactive)下的终端需要通过随机接入过程进入连接态后才能发送数据。这种idle/inactive下的数据传输机制会增大RRC信令开销、UE能耗或者数据传输时延等问题。为了保证终端在idle态能够直接发送数据,现有窄带物联网(narrow band internet of things,NB-IoT)或增强型机器类型通信(enhanced machine-type communication,eMTC)中的处理机制是网络通过给终端配置专用的周期性的PUR,从而终端可以通过PUR发送上行数据。In the current NR communication system, a terminal in an idle (idle) state or in an inactive state (inactive) needs to enter a connected state through a random access procedure before sending data. This idle/inactive data transmission mechanism will increase RRC signaling overhead, UE energy consumption, or data transmission delay. In order to ensure that the terminal can directly send data in the idle state, the processing mechanism in the existing narrowband internet of things (NB-IoT) or enhanced machine-type communication (eMTC) is that the network The terminal configures a dedicated periodic PUR, so that the terminal can send uplink data through the PUR.
6、重复传输次数6. Repeat transmission times
为了保证覆盖范围,NB-IoT/eMTC采用了重复传输的技术。其中,针对下行传输的最大重复传输次数是2048次,而针对上行传输的最大重复传输次数为128次。另外,物理下行共享信道(physical downlink share channel,PDSCH)或物理上行共享信道(physical uplink share channel,PUSCH)的重复传输次数可以由其调度的下行控制信息(downlink control information,DCI)动态指示,即DCI存在特定的比特域用于指示PDSCH或PUSCH的重复传输次数。同时,物理下行控制信道(physical downlink control channel,PDCCH)的最大重复次数(即Rmax)可以由RRC信令或者系统信息块(system information block,SIB)半静态配置。In order to ensure the coverage, NB-IoT/eMTC adopts the technology of repeated transmission. Among them, the maximum number of repeated transmissions for downlink transmission is 2048 times, and the maximum number of repeated transmissions for uplink transmission is 128 times. In addition, the number of repeated transmissions of the physical downlink share channel (PDSCH) or physical uplink shared channel (PUSCH) can be dynamically indicated by the downlink control information (DCI) scheduled by it, that is, There is a specific bit field in the DCI to indicate the number of repeated transmissions of the PDSCH or PUSCH. Meanwhile, the maximum number of repetitions (ie, Rmax) of the physical downlink control channel (PDCCH) may be semi-statically configured by RRC signaling or a system information block (SIB).
其次,在陆地网通信系统(如图3所示)中,由于同一个波束/小区的覆盖范围内不同地理位置的终端与基站之间的传播距离存在较大差异,因此在终端接收或者发送数据时,位于不同地理位置(比如小区中心或者小区边缘)的终端需要不同的数据信道的重复传输次数(即PDSCH/PUSCH/PRACH/PDCCH的重复传输次数)。目前,针对陆地网通信中的重复传输次数问题,网络可以通过由调度PDSCH/PUSCH的DCI中的特定比特域动态指示该PDSCH/PUSCH的重复传输次数。Secondly, in the land network communication system (as shown in Figure 3), due to the large difference in the propagation distance between the terminal and the base station in different geographical locations within the coverage of the same beam/cell, the terminal receives or sends data. When , terminals located in different geographic locations (such as cell center or cell edge) require different data channel repeated transmission times (ie, PDSCH/PUSCH/PRACH/PDCCH repeated transmission times). At present, for the problem of the number of repeated transmissions in land network communication, the network can dynamically indicate the number of repeated transmissions of the PDSCH/PUSCH through a specific bit field in the DCI that schedules the PDSCH/PUSCH.
最后,在NTN通信系统中,由于同一个波束/小区的覆盖范围内不同地理位置的终端与卫星之间的传播距离差异较小(即同一个波束/小区的覆盖范围内不同地理位置的终端对应的信号的路损差异较小),并且服务链路(serving link)以及供给链路(feeder link)的传播距离的变化具有规律性与周期性,因此这导致NTN通信系统可能不需要通过DCI来动态指示数据信道的重复传输次数,从而可以缩减DCI的比特大小(即DCI的有效负荷payload),以及提升PDCCH接收或者DCI的鲁棒性等。Finally, in the NTN communication system, due to the small difference in propagation distance between terminals and satellites in different geographical locations within the coverage of the same beam/cell (that is, terminals in different geographical locations within the coverage of the same beam/cell correspond to The path loss difference of the signal is small), and the variation of the propagation distance of the serving link (serving link) and the supply link (feeder link) is regular and periodic, so this leads to the NTN communication system. The number of times of repeated transmission of the data channel is dynamically indicated, so that the bit size of the DCI (ie, the payload of the DCI) can be reduced, and the robustness of the PDCCH reception or the DCI can be improved.
然而,在NTN通信系统中,由于终端与卫星之间的传播距离会时刻发生变化,因此还需要进一步研究终端在数据传输(包括下行数据传输或者上行数据传输)时数据信道的重复传输次数的问题。However, in the NTN communication system, since the propagation distance between the terminal and the satellite will change from time to time, it is necessary to further study the problem of the repeated transmission times of the data channel during data transmission (including downlink data transmission or uplink data transmission) of the terminal. .
结合上述描述,本申请实施例提供一种重复传输次数确定方法的流程示意图,其应用于非地面网络通信系统,请参阅图6。该方法包括:With reference to the above description, an embodiment of the present application provides a schematic flowchart of a method for determining the number of repeated transmissions, which is applied to a non-terrestrial network communication system, please refer to FIG. 6 . The method includes:
S610、网络设备向终端发送第一配置信息。S610. The network device sends the first configuration information to the terminal.
其中,第一配置信息可以用于确定数据信道的当前重复传输次数。The first configuration information may be used to determine the current repeated transmission times of the data channel.
需要说明的是,本申请实施例中的技术方案既适用于透明转发模式也适用于再生信号模式。在透明转发模式下,第一配置信息由位于地面的网络设备发送。在再生信号模式下,由于网络设备位于卫星,因此第一配置信息由位于卫星的网络设备发送。It should be noted that the technical solutions in the embodiments of the present application are applicable to both the transparent forwarding mode and the regeneration signal mode. In the transparent forwarding mode, the first configuration information is sent by the network device located on the ground. In the regenerative signal mode, since the network device is located at the satellite, the first configuration information is sent by the network device located at the satellite.
另外,数据信道的当前重复传输次数,可以理解为,当前数据信道重复传输次数或者当前数据信道上的数据传输所需的重复传输次数,对此不作具体限制。同时,当前重复传输次数,也可以理解为,第一重复传输次数,并且本申请实施例中的“第一”、“第二”等是用于区别不同对象,而不是用于描述特定顺序。In addition, the current number of repeated transmissions of the data channel can be understood as the number of repeated transmissions of the current data channel or the number of repeated transmissions required for data transmission on the current data channel, which is not specifically limited. Meanwhile, the current number of repeated transmissions can also be understood as the first number of repeated transmissions, and "first", "second", etc. in the embodiments of the present application are used to distinguish different objects, rather than to describe a specific order.
进一步需要说明的是,由于NTN通信系统中的卫星会在地面上产生波束或者小区,并且该卫星会沿着固定的轨道不断运动,因此位于该波束或者小区内的终端与该卫星之间的传播距离(或传播时延)会随着该卫星的位置变化而发生变化,从而导致终端在数据传输时数据信道的重复传输次数需要随着卫星的位置变化而相应调整。为此,本申请实施例考虑由网络设备向终端发送第一配置信息,并由终端根据第一配置信息确定数据信道的当前重复传输次数,从而实现网络设备与终端之间数据信道的重复传输次数随着终端与卫星之间的传播距离的不断变化而自适应调整,以及始终保证网络设备与终端之间在数据信道的重复传输次数上达成一致。It should be further noted that, since the satellite in the NTN communication system will generate a beam or cell on the ground, and the satellite will move along a fixed orbit, the propagation between the terminal located in the beam or the cell and the satellite is The distance (or propagation delay) will change with the position of the satellite, so that the number of repeated transmissions of the data channel needs to be adjusted according to the position of the satellite when the terminal transmits data. For this reason, the embodiment of the present application considers that the network device sends the first configuration information to the terminal, and the terminal determines the current repeated transmission times of the data channel according to the first configuration information, so as to realize the repeated transmission times of the data channel between the network device and the terminal. Adaptive adjustment is made with the constant change of the propagation distance between the terminal and the satellite, and an agreement on the number of repeated transmissions of the data channel is always guaranteed between the network device and the terminal.
具体的,第一配置信息可以是由无线资源控制RRC专用信令、媒体接入控制控制元素(MAC control element,MAC CE)、系统广播信息中的至少之一指示的。Specifically, the first configuration information may be indicated by at least one of RRC dedicated signaling, media access control element (MAC control element, MAC CE), and system broadcast information.
需要说明的是,由于NTN通信系统中的卫星的运行轨迹具有规律性与周期性,因此这导致NTN通信系统中服务链路(serving link)以及供给链路(feeder link)的传播距离的变化也具有规律性与周 期性,从而使得NTN通信系统可能不需要通过DCI来动态指示数据信道的重复传输次数以便缩减DCI的比特大小。为此,本申请实施例考虑由网络设备通过RRC专用信令、MAC CE、系统广播信息中的至少之一向终端发送第一配置信息以实现重复传输次数的自适应调整。It should be noted that since the orbits of satellites in the NTN communication system have regularity and periodicity, this leads to changes in the propagation distances of the serving link and the feeder link in the NTN communication system. With regularity and periodicity, the NTN communication system may not need to dynamically indicate the number of repeated transmissions of the data channel through DCI in order to reduce the bit size of the DCI. For this reason, the embodiment of the present application considers that the network device sends the first configuration information to the terminal through at least one of RRC dedicated signaling, MAC CE, and system broadcast information to realize adaptive adjustment of the number of repeated transmissions.
进一步的,系统广播信息可以包括系统信息块(system information block,SIB)信息。Further, the system broadcast information may include system information block (system information block, SIB) information.
具体的,数据信道可以包括以下至少一种:物理上行共享信道PUSCH、物理下行共享信道PDSCH、物理随机接入信道PRACH、预配置上行资源PUR。Specifically, the data channel may include at least one of the following: a physical uplink shared channel PUSCH, a physical downlink shared channel PDSCH, a physical random access channel PRACH, and a preconfigured uplink resource PUR.
可以理解的是,本申请实施例通过网络对PUSCH/PDSCH/PRACH/PUR的重复传输次数进行调整。It can be understood that, in this embodiment of the present application, the number of repeated transmissions of PUSCH/PDSCH/PRACH/PUR is adjusted through the network.
S620、终端获取来自网络设备的第一配置信息。S620. The terminal acquires the first configuration information from the network device.
S630、终端根据第一配置信息确定数据信道的当前重复传输次数。S630. The terminal determines the current repeated transmission times of the data channel according to the first configuration information.
可以看出,本申请实施例中,非地面网络通信系统中的网络设备向非地面网络通信系统中的终端发送第一配置信息;然后,该终端获取该第一配置信息,并根据该第一配置信息确定数据信道的当前重复传输次数。由于第一配置信息由网络配置,因此有利于实现网络设备与终端之间数据信道的重复传输次数随着终端与卫星之间的传播距离的不断变化而自适应调整,以及始终保证网络设备与终端之间在数据信道的重复传输次数上达成一致。It can be seen that, in the embodiment of the present application, the network device in the non-terrestrial network communication system sends the first configuration information to the terminal in the non-terrestrial network communication system; then, the terminal obtains the first configuration information, and according to the first configuration information The configuration information determines the current number of repeated transmissions for the data channel. Since the first configuration information is configured by the network, it is beneficial to realize the adaptive adjustment of the number of repeated transmissions of the data channel between the network device and the terminal as the propagation distance between the terminal and the satellite changes continuously, and to always ensure that the network device and the terminal are always Agree on the number of repeated transmissions of the data channel.
结合上述描述,下面本申请实施例将对第一配置信息进行具体介绍。With reference to the above description, the following embodiments of the present application will specifically introduce the first configuration information.
在一个可能的示例中,第一配置信息可以包括以下一种:起始取值索引信息和取值生效时延信息、第一映射关系信息、当前公共时间提前量、当前公共时间提前量变化速率。In a possible example, the first configuration information may include one of the following: starting value index information and value validating delay information, first mapping relationship information, current common timing advance, and current common timing advance change rate .
具体的,起始取值索引(index)信息可以用于确定取值列表信息中的目标取值,取值列表信息由网络配置;取值生效时延信息可以用于指示终端将目标取值作为当前重复传输次数的时延;取值列表(list)信息可以用于指示由多个重复传输次数(即至少两个重复传输次数)依顺序组成的列表。Specifically, the starting value index (index) information can be used to determine the target value in the value list information, and the value list information is configured by the network; the value validating delay information can be used to instruct the terminal to use the target value as the target value. The delay of the current repeated transmission times; the value list (list) information may be used to indicate a list composed of multiple repeated transmission times (ie, at least two repeated transmission times) in sequence.
需要说明的是,本申请实施例考虑第一配置信息包括起始取值索引信息和取值生效时延信息。此时,终端可以根据起始取值索引信息确定取值列表信息中的目标取值,再根据取值生效时延信息将目标取值作为当前重复传输次数。由于第一配置信息和取值列表信息均由网络设备配置,从而进一步实现网络设备与终端之间数据信道的重复传输次数随着终端与卫星之间的传播距离的不断变化而自适应调整,以及保证网络设备与终端之间在数据信道的重复传输次数上达成一致。It should be noted that, in this embodiment of the present application, it is considered that the first configuration information includes the starting value index information and the value validating delay information. At this time, the terminal may determine the target value in the value list information according to the initial value index information, and then use the target value as the current repeated transmission times according to the value effective delay information. Since both the first configuration information and the value list information are configured by the network device, the number of repeated transmissions of the data channel between the network device and the terminal is further adaptively adjusted as the propagation distance between the terminal and the satellite changes continuously, and Ensure that the network device and the terminal reach an agreement on the number of repeated transmissions of the data channel.
进一步的,取值列表信息可以满足以下至少一种方式:取值列表信息中的取值由终端与非地面网络通信系统中的卫星之间的传播距离确定、取值列表信息中取值之间的排列顺序与卫星的运动位置具有对应关系。Further, the value list information can satisfy at least one of the following ways: the value in the value list information is determined by the propagation distance between the terminal and the satellite in the non-terrestrial network communication system, and the value in the value list information is between the values. The arrangement order of the satellites has a corresponding relationship with the motion position of the satellites.
需要说明的是,由于卫星相对于地面的距离非常远,因此在一段时间内即便终端存在不断运动(即终端当前所在的位置不断变化)的情况,该终端与卫星之间的传播距离也变化较小。基于此,本申请实施例考虑将一段时间内终端所在的位置近似为固定不变,而主要分析由卫星的位置变化导致终端与卫星之间的传播距离的变化。It should be noted that, because the distance between the satellite and the ground is very far, even if the terminal is constantly moving (that is, the current position of the terminal is constantly changing) for a period of time, the propagation distance between the terminal and the satellite also changes relatively. Small. Based on this, the embodiment of the present application considers that the position of the terminal in a period of time is approximately fixed, and mainly analyzes the change in the propagation distance between the terminal and the satellite caused by the position change of the satellite.
同时,由于卫星具有固定的运行轨迹(如通过卫星星历表确定其运行轨迹),因此本申请实施例考虑由网络设备根据卫星的运行轨迹和终端当前所在的位置确定终端与卫星之间的传播距离的集合,再根据该传播距离的集合确定取值列表信息中的每个取值,从而建立终端与卫星之间的传播距离与取值列表信息中的取值之间的映射关系。另外,取值列表信息中取值之间的排列顺序与卫星的运行位置具有对应 关系,而该对应关系可以是一一对应的。At the same time, since the satellite has a fixed running track (for example, its running track is determined by using the satellite ephemeris), the embodiment of the present application considers that the network device determines the propagation between the terminal and the satellite according to the running track of the satellite and the current position of the terminal. The set of distances, and then determine each value in the value list information according to the set of propagation distances, thereby establishing a mapping relationship between the propagation distance between the terminal and the satellite and the values in the value list information. In addition, the arrangement order of the values in the value list information has a corresponding relationship with the operating positions of the satellites, and the corresponding relationship may be in one-to-one correspondence.
具体的,第一映射关系信息可以用于指示终端到非地面网络通信系统中的卫星的传播距离与重复传输次数之间的映射关系。Specifically, the first mapping relationship information may be used to indicate the mapping relationship between the propagation distance from the terminal to the satellite in the non-terrestrial network communication system and the number of repeated transmissions.
需要说明的是,本申请实施例考虑由网络设备根据卫星的运行轨迹和终端当前所在的位置确定终端与卫星之间的传播距离的集合,再建立该传播距离的集合与多个重复传输次数之间的映射关系以得到第一映射关系信息,从而由终端根据第一映射关系信息确定出当前重复传输次数,进一步实现网络设备与终端之间数据信道的重复传输次数随着终端与卫星之间的传播距离的不断变化而自适应调整,以及保证网络设备与终端之间在数据信道的重复传输次数上达成一致。It should be noted that in this embodiment of the present application, it is considered that the network device determines the set of propagation distances between the terminal and the satellite according to the running track of the satellite and the current position of the terminal, and then establishes the set of propagation distances and the number of repeated transmissions. The mapping relationship between the two is to obtain the first mapping relationship information, so that the terminal determines the current number of repeated transmissions according to the first mapping relationship information, and further realizes that the number of repeated transmissions of the data channel between the network device and the terminal increases with the number of times between the terminal and the satellite. The propagation distance is constantly changing and adaptively adjusted, and the network equipment and the terminal are guaranteed to reach an agreement on the number of repeated transmissions of the data channel.
具体的,当前公共时间提前量可以用于从第二映射关系信息中确定当前重复传输次数,第二映射关系信息由网络配置;当前公共时间提前量变化速率可以用于确定当前公共时间提前量;第二映射关系信息可以用于指示公共时间提前量与重复传输次数之间的映射关系。其中,该映射关系可以是一个公共时间提前量的区间对应一个重复传输次数。Specifically, the current common timing advance can be used to determine the current number of repeated transmissions from the second mapping relationship information, and the second mapping relationship information is configured by the network; the rate of change of the current common timing advance can be used to determine the current common timing advance; The second mapping relationship information may be used to indicate the mapping relationship between the common timing advance and the number of repeated transmissions. The mapping relationship may be that an interval of a common timing advance corresponds to a number of repeated transmissions.
需要说明的是,本申请实施例考虑第一配置信息包括当前公共时间提前量或者当前公共时间提前量变化速率。此时,终端可以根据当前公共时间提前量从第二映射关系信息中确定当前重复传输次数。或者,终端可以根据当前公共时间提前量变化速率确定当前公共时间提前量,再根据当前公共时间提前量从第二映射关系信息中确定当前重复传输次数。由于第一配置信息和第二映射关系信息均由网络设备配置,从而进一步实现网络设备与终端之间数据信道的重复传输次数随着终端与卫星之间的传播距离的不断变化而自适应调整,以及保证网络设备与终端之间在数据信道的重复传输次数上达成一致。It should be noted that, in this embodiment of the present application, it is considered that the first configuration information includes the current public timing advance or the change rate of the current public timing advance. At this time, the terminal may determine the current number of repeated transmissions from the second mapping relationship information according to the current common timing advance. Alternatively, the terminal may determine the current common timing advance according to the rate of change of the current common timing advance, and then determine the current number of repeated transmissions from the second mapping relationship information according to the current common timing advance. Since both the first configuration information and the second mapping relationship information are configured by the network device, the number of repeated transmissions of the data channel between the network device and the terminal can be further adjusted adaptively with the constant change of the propagation distance between the terminal and the satellite. And ensure that the network device and the terminal reach an agreement on the number of repeated transmissions of the data channel.
综合上述描述可知,由于第一配置信息包括的信息存在多种情况,因此本申请实施例可以存在多种技术方案以解决如何确定数据信道的重复传输次数的问题。下面本申请实施例将从以下情形对该多种技术方案进行具体介绍。From the above description, it can be seen that since the information included in the first configuration information has various situations, the embodiment of the present application may have various technical solutions to solve the problem of how to determine the number of repeated transmissions of the data channel.
