Description

一种资源确定方法、指示方法、中继站及节点A resource determination method, indication method, relay station and node

技术领域Technical Field

本发明涉及通信技术领域,尤其涉及资源确定方法、指示方法、中继站及节点。The present invention relates to the field of communication technology, and in particular to a resource determination method, an indication method, a relay station and a node.

背景技术Background technique

无线通信系统中的中继(Relay)技术,是在基站与终端之间增加了一个或多个中继节点,也可称为中继站,负责对无线信号进行一次或者多次的转发,也就是说,无线信号要经过多跳才能到达终端。Relay technology in wireless communication systems adds one or more relay nodes, also called relay stations, between the base station and the terminal, which are responsible for forwarding the wireless signal once or multiple times. In other words, the wireless signal has to go through multiple hops to reach the terminal.

无线中继技术不仅可用于扩展小区覆盖,弥补小区覆盖盲点,同时也可通过空间资源复用提升小区容量。对于室内覆盖,中继技术也可起到克服穿透损耗,提升室内覆盖质量的作用。因此在5G NR系统中设立了一个研究项目综合接入回程(Integrated Accessand Backhaul,简称IAB)用于研究相关的无线中继技术。IAB节点的概念类似于无线中继站的概念。下文中如没有特殊说明,不对中继站和IAB节点作区分。Wireless relay technology can not only be used to expand cell coverage and make up for cell coverage blind spots, but also to increase cell capacity through spatial resource reuse. For indoor coverage, relay technology can also overcome penetration loss and improve indoor coverage quality. Therefore, a research project Integrated Access and Backhaul (IAB) was established in the 5G NR system to study related wireless relay technologies. The concept of IAB nodes is similar to that of wireless relay stations. Unless otherwise specified below, no distinction is made between relay stations and IAB nodes.

以较简单的两跳中继为例,无线中继就是将一个基站与终端之间的链路分割为基站与中继站之间的链路,以及,中继站和终端之间的链路,一共两个链路,从而有机会将一个质量较差的链路替换为两个质量较好的链路,以获得更高的链路容量及更好的覆盖。Taking the simpler two-hop relay as an example, wireless relay divides the link between a base station and a terminal into a link between the base station and the relay station, and a link between the relay station and the terminal, a total of two links. This provides an opportunity to replace a link of poor quality with two links of better quality to obtain higher link capacity and better coverage.

如图1所示,给出一个多跳的无线中继的场景,图中所示的是4跳的场景,也就是说信号从宿主基站(donor gNB)到最终的终端(User Equipment,简称UE)中间经过了中继站2、中继站4以及中继站5的信号转发。这中间的无线链路的数目也就是通常所说的“跳数”。As shown in Figure 1, a multi-hop wireless relay scenario is given. The figure shows a 4-hop scenario, which means that the signal from the donor gNB to the final terminal (User Equipment, referred to as UE) passes through relay station 2, relay station 4, and relay station 5 for signal forwarding. The number of wireless links in between is also commonly referred to as the "hop count".

为了满足通信的有效性和鲁棒性,中继节点可以在通信的过程中随时变换上一跳的宿主,这个宿主有可能是基站或者中继站。由于动态的选择链路质量更好的节点,或者选择时延最短也就是跳数最少的节点,导致中继站的跳数不断的发生变化。In order to ensure the effectiveness and robustness of communication, the relay node can change the previous hop host at any time during the communication process. This host may be a base station or a relay station. Due to the dynamic selection of nodes with better link quality or the shortest delay, that is, the least number of hops, the number of hops of the relay station is constantly changing.

由于中继站的跳数不断的发生变化,中继站无法获知当前所在的跳数,导致中继站无法获得最优的资源配置。Since the number of hops of the relay station is constantly changing, the relay station cannot know the current hop number, resulting in the relay station being unable to obtain the optimal resource configuration.

如图2所示,本发明的实施例提供一种资源确定方法,应用于中继站,该方法包括:As shown in FIG. 2 , an embodiment of the present invention provides a resource determination method, which is applied to a relay station. The method includes:

步骤21,从至少一个节点接收指示信息,所述至少一个节点与所述中继站通讯连接,且所述至少一个节点是所述中继站的上一级节点;Step 21, receiving indication information from at least one node, wherein the at least one node is in communication connection with the relay station, and the at least one node is an upper-level node of the relay station;

该步骤中,与中继站通讯连接的节点可以是中继站的一个上一级节点,如图1中所示,中继站4的上一级节点为中继站2,中继站5的上一级节点为中继点4;In this step, the node that is in communication connection with the relay station may be a parent node of the relay station. As shown in FIG1 , the parent node of relay station 4 is relay station 2, and the parent node of relay station 5 is relay point 4;

这里,与中继站通讯连接的节点也可以是中继站的多个上一级节点,如图1中所示,中继站5可以与中继站4通讯连接,也可以同时与中继站3通讯连接,当然,也可以同时与中继站7通讯连接等。Here, the nodes that are communicatively connected to the relay station can also be multiple upper-level nodes of the relay station. As shown in Figure 1, relay station 5 can be communicatively connected to relay station 4, and can also be communicatively connected to relay station 3 at the same time. Of course, it can also be communicatively connected to relay station 7 at the same time, etc.

该场景中,中继站在通信的过程中随时变换上一跳的宿主节点,以获得质量较好的通讯链路或者时延最短的通讯链路。以中继站5为例,该中继站的宿主节点变换为中继站4时,接收来自中继站4的指示信息,该指示信息用于指示中继站5进行资源信息的获取,从而可以获得该中继站5的资源配置信息。In this scenario, the relay station changes the previous hop host node at any time during the communication process to obtain a communication link with better quality or a communication link with the shortest delay. Taking relay station 5 as an example, when the host node of the relay station is changed to relay station 4, it receives indication information from relay station 4, which is used to instruct relay station 5 to obtain resource information, so that the resource configuration information of relay station 5 can be obtained.

步骤22,根据所述指示信息,确定所述中继站的资源配置。Step 22: Determine resource configuration of the relay station according to the indication information.

该实施列中,中继站通过接收其上一级节点发送的指示信息,并根据该指示信息,可以确定该中继站的资源配置,,从而避免由于动态的选择其上一级节点,导致中继站的跳数不断的发生变化时,该中继站的资源配置无法确定的问题,本发明的实施例可以确定该中继站的资源配置,从而可以根据该资源配置,实现通讯质量的优化。In this embodiment, the relay station receives indication information sent by its upper-level node, and according to the indication information, it can determine the resource configuration of the relay station, thereby avoiding the problem that the resource configuration of the relay station cannot be determined when the number of hops of the relay station constantly changes due to the dynamic selection of its upper-level node. The embodiment of the present invention can determine the resource configuration of the relay station, so that the communication quality can be optimized according to the resource configuration.

这里的SSB是指在5G NR中,主同步信号(Primary Synchronization Signal,简称PSS)、辅同步信号(Secondary Synchronization Signal,简称SSS)和PBCH共同构成一个信号SSB(SS/PBCH block),如图3所示,SSB在时域上共占用4个正交频分复用(OrthogonalFrequency Division Multiplexing,简称OFDM)符号,频域共占用240个子载波(20个PRB)。这里的PRB是physical resource block的简称,即物理资源块,其中PBCH是物理广播信道,可以承载主系统信息块(master information block,简称MIB)。The SSB here means that in 5G NR, the primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the PBCH together constitute a signal SSB (SS/PBCH block). As shown in Figure 3, the SSB occupies a total of 4 orthogonal frequency division multiplexing (OFDM) symbols in the time domain and a total of 240 subcarriers (20 PRBs) in the frequency domain. The PRB here is the abbreviation of physical resource block, that is, physical resource block, where PBCH is a physical broadcast channel that can carry the master information block (MIB).

上述1)中,该PBCH承载的指示信息可以是所述SSB中的PBCH承载的所述中继站的跳数或者所述中继站的资源配置信息;In the above 1), the indication information carried by the PBCH may be the number of hops of the relay station carried by the PBCH in the SSB or the resource configuration information of the relay station;

这里的RMSI是指,5G NR中,支持按需系统信息块(on-demand SIB)传输,考虑尽可能快速同步与接入,将必要的系统信息分为两部分:MIB与RMSI,其它非必要信息,有需求时再读取。RMSI实质类似于LTE中的SIB1,通知上行频率(UL freq)、上下行时隙配置(TDDconfiguration)等信息。The RMSI here refers to the support of on-demand SIB transmission in 5G NR. Considering the fastest synchronization and access, the necessary system information is divided into two parts: MIB and RMSI. Other non-essential information is read when needed. RMSI is essentially similar to SIB1 in LTE, notifying information such as uplink frequency (UL freq), uplink and downlink time slot configuration (TDD configuration), etc.

这时,中继站的上一级节点广播SSB,该SSB携带了第一级MIB,中继站通过第一级MIB去预定资源上读取第二级MIB,这个预定资源可以和第一级MIB(或者SSB)的时间位置、频率位置、准共址(Quasi Co-Location,简称QCL)配置和/或SSB编号等信息有关或者由第一级MIB中携带的信息通知,并且第二级MIB所占用的物理资源和第一级MIB不同,例如可以不在SSB所占用的资源上;中继站去预定资源上读取第二级MIB,获得中继站所在的跳数或者该中继站的资源配置信息。At this time, the upper-level node of the relay station broadcasts SSB, which carries the first-level MIB. The relay station reads the second-level MIB on the reserved resources through the first-level MIB. The reserved resources may be related to the time position, frequency position, quasi co-location (Quasi Co-Location, QCL) configuration and/or SSB number of the first-level MIB (or SSB) or notified by the information carried in the first-level MIB, and the physical resources occupied by the second-level MIB are different from those of the first-level MIB, for example, they may not be on the resources occupied by the SSB; the relay station reads the second-level MIB on the reserved resources to obtain the number of hops where the relay station is located or the resource configuration information of the relay station.

本发明的实施例中,中继站的资源配置可以包括但不限于:中继站的导频的配置、同步信号的位置配置、无线传输资源的位置配置等。In the embodiments of the present invention, the resource configuration of the relay station may include but is not limited to: the configuration of the pilot of the relay station, the location configuration of the synchronization signal, the location configuration of the wireless transmission resource, etc.

具体来说,中继站在接收所述SSB中的PBCH承载的消息的预设字段指示的所述中继站的跳数,或者,所述SSB中的PBCH承载的MIB消息的冗余字段指示的所述中继站的跳数,或者,所述SSB中的PBCH的冗余资源承载的所述中继站的跳数,或者,所述SSB中的PBCH承载的导频DMRS携带的所述中继站的跳数,或者,所述RMSI或者OSI的预设字段指示的所述中继站的跳数,或者,所述RMSI或者OSI的冗余字段指示的所述中继站的跳数,或者,所述第二级MIB消息的冗余字段指示所述中继站的跳数时,可以直接从该指示信息的相应字段中获得该中继站的跳数,继而,该中继站可以依据其自身的跳数,获得该中继站的资源配置信息,在通讯时,中继站在得知自己的跳数时,会依据跳数与自身的资源配置信息的对应关系,确定该中继站的资源配置,比如,跳数为第3跳时,采用无线传输资源子帧3,6,9进行通讯,跳数为第2跳时,采用子帧2,5,8进行通讯,并进一步利用这些资源配置信息进行通讯,以获得较好的通讯质量;Specifically, the relay station receives the hop count of the relay station indicated by the preset field of the message carried by the PBCH in the SSB, or the hop count of the relay station indicated by the redundant field of the MIB message carried by the PBCH in the SSB, or the hop count of the relay station carried by the redundant resources of the PBCH in the SSB, or the hop count of the relay station carried by the pilot DMRS carried by the PBCH in the SSB, or the hop count of the relay station indicated by the preset field of the RMSI or OSI, or the hop count of the relay station indicated by the redundant field of the RMSI or OSI, or When the redundant field of the second-level MIB message indicates the hop count of the relay station, the hop count of the relay station can be directly obtained from the corresponding field of the indication information. Then, the relay station can obtain the resource configuration information of the relay station based on its own hop count. During communication, when the relay station learns its own hop count, it will determine the resource configuration of the relay station based on the correspondence between the hop count and its own resource configuration information. For example, when the hop count is the third hop, wireless transmission resource subframes 3, 6, and 9 are used for communication. When the hop count is the second hop, subframes 2, 5, and 8 are used for communication. These resource configuration information are further used for communication to obtain better communication quality.

同样的,中继站在接收到PBCH承载的所述中继站的资源配置信息,或者,RMSI或者OSI携带的所述中继站的资源配置信息,或者,所述第二级MIB消息的冗余字段指示所述中继站的资源配置信息时,可以直接解码该接收到的信息,获得该中继站的资源配置信息,并进一步利用该资源配置信息进行通讯,以获得较好的通讯质量。Similarly, when the relay station receives the resource configuration information of the relay station carried by PBCH, or the resource configuration information of the relay station carried by RMSI or OSI, or the redundant field of the second-level MIB message indicates the resource configuration information of the relay station, the relay station can directly decode the received information, obtain the resource configuration information of the relay station, and further use the resource configuration information to communicate to obtain better communication quality.

图4中所示是中继站与两个上级节点通讯连接的场景,与多个上级节点通讯连接的场景相类似。相应的,上述步骤22中,可以包括:FIG4 shows a scenario where a relay station is connected to two upper-level nodes for communication, which is similar to a scenario where a plurality of upper-level nodes are connected for communication. Accordingly, the above step 22 may include:

步骤221),根据所述至少两个上一级节点的跳数,确定所述中继站的跳数;例如,可以通过以下方式确定中继站的跳数:Step 221), according to the hop counts of the at least two upper-level nodes, determine the hop count of the relay station; for example, the hop count of the relay station can be determined in the following manner:

A.将至少两个上一级节点的跳数的最小值+1,确定为所述中继站的跳数;A. Determine the minimum value of the hop counts of at least two upper-level nodes + 1 as the hop count of the relay station;

B.将至少两个上一级节点的跳数的最大值+1,确定为所述中继站的跳数;B. Determine the maximum value of the hop counts of at least two upper-level nodes plus 1 as the hop count of the relay station;

C.通过算式:所述确定所述中C. Through the formula: Determine the

For the specified expression, k is an integer from 1 to N.

步骤222)根据所述中继站的跳数,确定所述中继站的资源配置。Step 222) Determine the resource configuration of the relay station according to the hop count of the relay station.

以中继站5分别与中继站4和中继站3通讯连接为例,而中继站3和中继站4的跳数不一样的时候,中继站5的跳数可以基于中继站3和中继站4的跳数进行确定:For example, relay station 5 is connected to relay station 4 and relay station 3 respectively, and the hop counts of relay station 3 and relay station 4 are different, the hop count of relay station 5 can be determined based on the hop counts of relay station 3 and relay station 4:

如:节点5的跳数=min(节点3的跳数,节点4的跳数)+1;For example: the hop count of node 5 = min (the hop count of node 3, the hop count of node 4) + 1;

或者,节点5的跳数=max(节点3的跳数,节点4的跳数)+1;Or, the hop count of node 5 = max(the hop count of node 3, the hop count of node 4) + 1;

或者,节点5的跳数=floor((节点3的跳数+节点4的跳数)/2)+1。Alternatively, the hop count of node 5=floor((the hop count of node 3+the hop count of node 4)/2)+1.

当然,当中继站3与中继站4的跳数一样时,也同样可以采用上述方式进行确定,比如,求中继站3与中继站4的跳数的最小值时,可以任选一个作为该中继站的跳数;求最大值时,同样可以类似任选一个作为该中继站的跳数。Of course, when the number of hops of relay station 3 is the same as that of relay station 4, the above method can also be used for determination. For example, when finding the minimum value of the number of hops of relay station 3 and relay station 4, you can select any one as the hop number of the relay station; when finding the maximum value, you can also select any one as the hop number of the relay station.
