Description

一种资源配置的方法及其装置 技术领域
本申请涉及通信技术领域，尤其涉及一种资源配置的方法及其装置。
背景技术
目前，多种新业务新应用需求的持续产生，终端直连通信(也叫侧行链路，Sidelink，SL)对传输宽度、通信速域、通信时延、可靠性、可扩展性等性能要求会越来越高，如果仅依靠运营商有限的授权频谱，则无法满足未来潜在的多样化应用场景和需求，所以需要研究涉及能应用在非授权频段上的终端侧行链路(sidelink-unlicensed，SL-U)技术。
在非授权频段上，需要满足OCB(OccupiedChannel Bandwidth，在非授权频谱上针对发送信号的占用带宽)要求，即每次传输需要占满每一个LBT(Listen before Talk，先听后说)子带(如20MHz)带宽的80％。
但是，目前在SL-U系统中尚且缺乏在LBT子带上配置资源池的有效手段。

第二种：以子信道为粒度的资源分配方式，资源池需要定义在LBT子带上，设计资源池到IRB索引之间的映射关系，在资源池所映射的IRB索引中，确定子信道到IRB索引的映射。所以，为了满足OCB要求，需要设计资源池到IRB索引之间的映射，以实现资源池的资源配置。然而，不管在SL-U系统中使用上述第一种或第二种资源分配方式，目前在SL-U系统中尚且缺乏在LBT子带上配置资源池的有效手段。
为此，本申请提出了一种资源配置的方法及其装置，可以应用于SL-U系统，通过提供一种资源池到梳尺资源块索引之间的映射方式，以实现资源池的资源配置，可以在终端侧行链路非授权频段上满足OCB要求，从而可以满足未来潜在的多样化应用场景和需求。
为了更好的理解本申请实施例公开的一种资源配置的方法及其装置，下面首先对本申请实施例使用的通信系统进行描述。

本申请实施例的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备是用户侧的一种用于接收或发射信号的实体，如手机。第一终端设备和第二终端设备也可以称为终端设备、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的资源配置的方法及其装置进行详细地描述。
请参见图2，图2为本申请实施例提供的一种资源配置的方法的流程图。需要说明的是，本申请实施例的资源配置的方法可应用于终端侧行链路非授权频段系统上，该方法可以由网络设备执行。如图2所示，该资源配置的方法可以包括但不限于如下步骤。
在步骤201中，将梳尺资源块映射到至少一个资源池。
其中，在本申请的实施例中，每个资源池的配置信息指示了对应资源池所配置的梳尺资源块索引的数量及位置；同一个梳尺资源块索引中连续的两个梳尺资源块相隔的资源块数值为M，M由子载波间隔的大小确定。
需要说明的是，在NR-U系统中引入了梳尺资源块(也叫交错资源块，Interlaced Resource Block，IRB)，即连续的两个梳尺资源块间隔M个资源块，对于梳尺资源块索引m，其包括的物理资源块PRB为{m,M+m,2M+m,3M+m,…}，其中m∈{0,1,…,M-1}。在NR-U系统中，针对15kHz和30kHz两种子载波间隔分别定义了IRB结构，如下表所示。
表4.4.4.6-1：资源块交错的数量
μ M
0 10
1 5
例如，如图3所示，子载波间隔SCS＝30khz,M＝5时，共有5个梳尺资源块索引，对于1个梳尺资源块索引，如梳尺资源块索引0，该梳尺资源块索引中包含梳尺资源块为PRB{0,5,10,15,20,25,30,35,40,45}。又如，如图4所示，子载波间隔SCS＝15khz,M＝10时，共有10个梳尺资源块索引，共有100个PRB，其中，对于1个梳尺资源块索引，如梳尺资源块索引0，该梳尺资源块索引中包含梳尺资源块为PRB{0,10,20,30,40,50,60,70,80,90}。本申请继续引入梳尺资源块，由此，通过引入梳尺资源块，可以减少SL-U系统中指示送配置的频域资源的开销。
在本申请的实施例中，网络设备在配置资源池时，可以将系统中的梳尺资源块映射到一个或多个资源池。作为一种示例，可以基于资源池与梳尺资源块索引的映射规则，将梳尺资源块映射到一个或多个资源池。其中，该映射规则可以是协议约定的。
在步骤202中，确定至少一个资源池中每个资源池的配置信息。
在本申请的实施例中，网络设备在配置资源池时，可以将系统中的梳尺资源块映射到一个或多个资源池，也就是说，可以将系统的梳尺资源块划分为一个或多个资源池，以形成系统的资源池配置信息，该资源池配置信息包含每个资源池的配置信息，每个资源池的配置信息中指示了对应资源池所配置的梳尺资源块索引的数量及位置，从而实现了资源池的资源配置。可选的，每个资源池可以对应唯一的资源池索引号，通过该资源池索引号指示使用对应资源池包含的梳尺资源块，用于承载终端设备的控制信息和/或数据信息。
通过实施本申请实施例，将梳尺资源块划分为一个或多个资源池，以形成每个资源池的配置信息，其中每个资源池的配置信息指示了对应资源池所配置的梳尺资源块索引的数量及位置。由此可见，本申请通过提供一种资源池到梳尺资源块索引之间的映射方式，以实现资源池的资源配置，可以在终端侧行链路非授权频段上满足OCB要求，从而可以满足未来潜在的多样化应用场景和需求。
为了实现上述实施例，本申请还提供了另一种资源配置的方法。在本申请的一些实施例中，如图5所示，该资源配置的方法可以包括但不限于如下步骤。
在步骤501中，根据资源池与梳尺资源块索引的映射规则，确定一个资源池含有的梳尺资源块索引的数目和梳尺资源块索引的位置。
可以理解，在本申请的实施例中，该资源池与梳尺资源块索引的映射规则可以是由协议约定的，例如，可以通过协议约定资源池与梳尺资源块索引的映射规则，这样，可以根据该资源池与梳尺资源块索引的映射规则，确定一个资源池含有的梳尺资源块索引的数目和梳尺资源块索引的位置，以便利用该映射规则，确定网络设备配置的资源池的配置信息。
在步骤502中，根据一个资源池含有的梳尺资源块索引的数目和梳尺资源块索引的位置，将梳尺资源块映射到至少一个资源池，确定至少一个资源池中每个资源池的配置信息。
也就是说，可以根据一个资源池应含有的梳尺资源块索引的数目和梳尺资源块索引的位置，来将系统的梳尺资源块映射到至少一个资源池，以便可以确定网络设备配置的资源池的配置信息，该配置信息指示了对应资源池所配置的梳尺资源块索引的数量和位置。
需要说明的是，在本申请的实施例中，1个资源池可以映射到1个LBT子带中，或者，1个资源池可以映射到多个LBT子带中。不同的映射方式对应着不同的映射规则。下面将结合实施例从1个资源池映射到1个LBT子带中，以及1个资源池映射到多个LBT子带这两个方面分别介绍该资源池与梳尺资源块索引的映射规则。
针对1个资源池映射到1个LBT子带的情况：
在一种实现方式中，该资源池与梳尺资源块索引的映射规则为：一个资源池映射到一个先听后说LBT子带中连续或非连续的N1个梳尺资源块索引上；其中，N1为小于或等于M的正整数。
也就是说，当1个资源池映射到1个LBT子带中时，在1个LBT子带中，1个资源池可以映射到连续或非连续的N1个梳尺资源块索引上，1≤N1≤M。
可选的，所述一个资源池映射到一个先听后说LBT子带中连续或非连续的整数N1个梳尺资源块 索引上的实现方式可如下：从一个LBT子带中的第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号将连续或非连续的整数N1个IRB索引一一映射到对应资源池上；其中，N1小于M。
举例而言，在1≤N1＜M情况下，资源池映射到梳尺资源块索引时，资源池可以从第一个LBT子带中第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号将连续或非连续的整数N1个IRB索引一一映射到对应资源池上。例如，资源池映射到梳尺资源块索引时，资源池可以从第一个LBT子带中序号为0的梳尺资源块索引开始映射，按照梳尺资源块索引所在的逻辑编号将连续或非连续的整数N1个IRB索引一一映射到对应资源池上。
作为一种示例，以LBT子带的子载波间隔SCS＝15khz，M＝10，N1＝8为例，N1＜M，该资源池与梳尺资源块索引的映射规则可理解为：1个资源池映射到1个LBT子带中连续或非连续的8个梳尺资源块索引上。例如，1个资源池可以映射到1个LBT子带中序号为0～7的梳尺资源块索引上，即1个资源池可以映射到1个LBT子带中连续的8个梳尺资源块索引上；又如，1个资源池可以映射到1个LBT子带中非连续8个梳尺资源块索引上，比如该非连续8个梳尺资源块索引分别为索引序号为0,1,2,3,5,6,7,8。举例，以两个资源池(包括资源池0和资源池1)为例，资源池0映射到第一个LBT子带(如子带0)中序号为0～7的梳尺资源块索引上，资源池1映射到第二个LBT子带(如子带1)中序号为0～7的梳尺资源块索引上，即1个资源池映射到1个LBT子带中连续的N1个梳尺资源块索引上。
在本实施例中，利用该资源池与梳尺资源块索引的映射规则进行资源池到梳尺资源块索引映射时，可以使用比特位图进行指示。在一种实现方式中，每个资源池的配置信息为比特位图的形式，比特位图的长度为M，其中，比特位图中每个比特位对应一个梳尺资源块索引，比特位图之中比特位数值为1用于指示映射到对应资源池，比特位图之中比特位数值为0用于指示不映射到对应资源池。
例如，使用比特位图(bitmap)对一个LBT子带中的10个梳尺资源块索引进行指示，该比特位图中每个比特对应一个梳尺资源块索引，该比特位图中比特位数值为1，表示该比特位对应的梳尺资源块索引映射到该资源池，比特位图之中比特位数值为0，表示该比特位对应的梳尺资源块索引不映射到该资源池。需要说明的是，比特位图的最低位对应LBT子带中序号为0的梳尺资源块索引，比如，以1个资源池映射到1个LBT子带中非连续的5个梳尺资源块索引上，比特位图为0101010101为例，则表示梳尺资源块索引为1,3,5,7,9映射到该资源池。
在本实施例中，在资源池可以映射连续的梳尺资源块索引的情况下，可以通过起始梳尺资源块索引和连续梳尺资源块索引个数的指示信息进行指示。在一种实现方式中，资源池与梳尺资源块索引的映射规则为：一个资源池映射到一个LBT子带中连续的整数N1个梳尺资源块索引上；其中，每个资源池的配置信息包括用以指示对应资源池所配置的起始梳尺资源块索引和连续梳尺资源块索引个数的指示信息。
也就是说，在资源池与梳尺资源块索引的映射规则为一个资源池映射到一个LBT子带中连续的整数N1个梳尺资源块索引上时，网络设备配置的资源池的配置信息中可以包括用以指示对应资源池所配置的起始梳尺资源块索引和连续梳尺资源块索引个数的指示信息。由此，通过该指示方式可实现资源池配置的指示。
在一种实现方式中，一个资源池包括X个子信道，X为正整数；所述一个资源池映射到一个先听后说LBT子带中连续或非连续的整数N1个梳尺资源块索引上的实现方式可如下：一个资源池中的X个子信道映射到N1个梳尺资源块索引上，其中，子信道与梳尺资源块索引的映射规则为：以一个资源池所映射的第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号将N1个梳尺资源块索引映射到一个资源池中的子信道上。
举例而言，在1个资源池只映射到1个LBT子带中部分的梳尺资源块索引，此时资源池中的X个子信道到梳尺资源块索引的映射可如下：X个子信道映射到N1个梳尺资源块索引上，且子信道到梳尺资源块索引的映射是以该资源池所映射的第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号的梳尺资源块索引映射到该资源池中的子信道上。作为一种示例，以1个资源池包含2个子信道， 该2个子信道映射到12个梳尺资源块索引上，12个梳尺资源块索引从第一个LBT子带中序号为0的梳尺资源块索引(如IRB index 0)开始，按照梳尺资源块索引所在的逻辑编号开始映射，子信道0映射到逻辑编号梳尺资源块索引0～梳尺资源块索引5上，子信道1映射到逻辑编号梳尺资源块索引6～梳尺资源块索引11上。
可选的，所述一个资源池映射到一个先听后说LBT子带中连续或非连续的整数N1个梳尺资源块索引上的实现方式可如下：一个资源池映射到一个LBT子带中的M个IRB索引上；其中，N1等于M。也就是说，在N1等于M情况下，资源池映射到梳尺资源块索引时，1个资源池可以映射到1个LBT子带中全部的M个梳尺资源块索引。
在一种实现方式中，该资源池与梳尺资源块索引的映射规则为：一个资源池映射到一个LBT子带中连续或非连续的N2个梳尺资源块索引上；其中，N2为大于1且小于所述M的非整数。
需要说明的是，可选的，在资源池映射时，可以从一个LBT子带中的第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号将连续或非连续的N2个梳尺资源块索引一一映射到对应资源池上；其中，N2个梳尺资源块索引包括：第一个梳尺资源块索引至第L个梳尺资源块索引，以及第L+1个梳尺资源块索引中的l个梳尺资源块；L为N2的向下取整后得到的整数，l的取值基于N2中小数部分与M的关系。也就是说，l的取值可由N2中小数部分与M的关系来确定的，比如M＝10，N2＝2.5，则可以确定l的取值为5；又如，M＝5，N2＝2.5，则可以确定l的取值为2；再如，M＝10，N2＝2.3，则可以确定l的取值为3。
举例而言，在资源池映射时，可以从第一个LBT子带中的第一个梳尺资源块索引开始，如从第一个LBT子带中序号为0的梳尺资源块索引开始映射，按照梳尺资源块索引所在的逻辑编号将连续或非连续的N2个梳尺资源块索引一一映射到对应资源池上。例如，以N2＝2.5为例，1个资源池映射到连续的2.5个梳尺资源块索引上，如梳尺资源块索引0,1,2，则该1个资源池可以映射到序号为0的梳尺资源块索引，以及映射到序号为1的梳尺资源块索引，以及映射到序号为2的梳尺资源块索引中的部分梳尺资源块上，比如在序号为2的梳尺资源块索引上，该资源池只映射该序号为2的梳尺资源块索引中的5个梳尺资源块。其中，该5个梳尺资源块可以是序号为2的梳尺资源块索引中前5个梳尺资源块，或者，该5个梳尺资源块还可以是序号为2的梳尺资源块索引中奇数序号的5个梳尺资源块，或者，该5个梳尺资源块还可以是序号为2的梳尺资源块索引中偶数序号的5个梳尺资源块，具体可以根据实际应用来决定，对此不做具体限定。
在一种实现方式中，一个资源池包括X个子信道，X为正整数；所述一个资源池映射到一个LBT子带中连续或非连续的N2个梳尺资源块索引上的实现方式可如下：一个资源池中的X个子信道映射到N2个梳尺资源块索引上，其中，子信道与梳尺资源块索引的映射规则为：一个资源池所映射的第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号将N2个梳尺资源块索引映射到一个资源池中的子信道上。
举例而言，在1个资源池只映射到1个LBT子带中部分的N2个梳尺资源块索引，此时资源池中的X个子信道到梳尺资源块索引的映射可如下：X个子信道映射到N2个梳尺资源块索引上，且子信道到梳尺资源块索引的映射是以该资源池所映射的第一个梳尺资源块索引开始，按照梳尺资源块索引所在的逻辑编号的梳尺资源块索引映射到该资源池中的子信道上。
作为一种示例，以1个资源池包含2个子信道，该2个子信道映射到12.5个梳尺资源块索引上，12.5个梳尺资源块索引从第一个LBT子带中序号为0的梳尺资源块索引(如IRB index 0)开始，按照梳尺资源块索引所在的逻辑编号开始映射，子信道0映射到逻辑编号梳尺资源块索引0～梳尺资源块索引5上，子信道1映射到逻辑编号梳尺资源块索引6～梳尺资源块索引11上，该子信道1还映射到逻辑编号梳尺资源块索引12中的5个梳尺资源块。
针对1个资源池映射到多个LBT子带的情况：
在一种实现方式中，该资源池与梳尺资源块索引的映射规则为：一个资源池映射到多个LBT子带中N3个梳尺资源块索引上；其中，N3为大于M的整数，一个资源池在每个LBT子带中连续或非连续映射到相同序号的梳尺资源块索引。
举例而言，1个资源池映射到N个梳尺资源块索引上，该1个资源池在每个LBT子带连续或非连续映射到相同序号的梳尺资源块索引。作为一种示例，1个资源池需要映射到16个梳尺资源块索引上，则该资源池可以映射到子带0中序号为0～7的8个梳尺资源块索引上，再继续映射到子带1中序号为0～7的8个梳尺资源块索引上。
可选的，每个资源池的配置信息包括子带指示信息和梳尺资源块索引指示信息，其中，子带指示信息用于指示对应资源池所映射的多个LBT子带，梳尺资源块索引指示信息用于指示对应资源池在每个LBT子带中所映射的梳尺资源块索引。也就是说，在该资源池与梳尺资源块索引的映射规则为：1个资源池在每个LBT子带连续或非连续映射到相同序号的梳尺资源块索引的情况下，网络设备配置的资源池的配置信息可以包括子带指示信息和梳尺资源块索引指示信息，其中，子带指示信息和梳尺资源块索引指示信息两者可以独立编码，或者，该子带指示信息和梳尺资源块索引指示信息也可以联合编码。
在一种实现方式中，该资源池与梳尺资源块索引的映射规则为：一个资源池映射到多个LBT子带中N3个梳尺资源块索引上；其中，N3为大于M的整数，一个资源池在每个LBT子带映射的梳尺资源块索引序号不同。
也就是说，1个资源池可以映射到多个LBT子带中N3个梳尺资源块索引上，其中，1个资源池在每个LBT子带映射的梳尺资源块索引序号不同，且独立配置，配置方法由如下两种：
方法1：1个资源池映射到N3个梳尺资源块索引上，将子带中的梳尺资源块按照频率位置进行编号，例如起始频率最低的子带0的梳尺资源块物理编号为0-9，逻辑编号为0-9，次低的子带1的梳尺资源块物理编号为0-9，逻辑编号为10-19，依次类推；(预)配置的时候指示资源池所映射的梳尺资源块逻辑编号。基于该配置方式，网络设备配置的资源池的配置信息可以包括指示信息，该指示信息用于指示对应资源池所映射的梳尺资源块索引所在的逻辑编号。
例如，如图6所示，N3＝12，1个资源池映射到12个梳尺资源块索引，对于资源池0，映射到第一个LBT子带(如图6中的子带0)中序号为0-9梳尺资源块索引上，再映射到第2个LBT子带(如图6中的子带1)中逻辑编号为10-11的2个梳尺资源块索引上，即第2个LBT子带的物理编号为0-1的2个梳尺资源块索引上。
方法2：首先指示资源池所映射的子带，再指示对应子带所映射的梳尺资源块索引。在本示例中，每个资源池的配置信息包括子带指示信息和梳尺资源块索引指示信息，其中，子带指示信息用于指示对应资源池所映射的多个LBT子带，梳尺资源块索引指示信息用于指示对应资源池在每个LBT子带中所 映射的梳尺资源块索引。
也就是说，当一个资源池在每个LBT子带映射的梳尺资源块索引序号不同时，可以利用两个指示字段来指示对应资源池所配置的梳尺资源块索引的数量及位置，比如，每个资源池的配置信息包括子带指示信息和梳尺资源块索引指示信息，该子带指示信息用于指示对应资源池所映射的多个LBT子带，梳尺资源块索引指示信息用于指示对应资源池在每个LBT子带中所映射的梳尺资源块索引。
需要说明的是，在本申请的一些实施例中，网络设备将系统中的梳尺资源块映射到多个资源池的资源池配置信息需要通过一定的方式通知给系统的终端设备。网络设备配置的资源池的配置信息为公共信息，应为所有可用终端设备共同获知，可以采用系统预定义，系统广播消息，或高层信令，如无线资源控制消息进行指示。网络设备或具有可发送资源池配置信息权限的终端设备可通过相应的信令对采用的资源池配置进行指示。
通过实施本申请实施例，通过系统预定义的资源池与梳尺资源块索引的映射规则进行资源池配置，可以确定1个资源池包含的梳尺资源块索引的数目和梳尺资源块索引的位置，以便利用该映射规则进行资源池的配置，可以在终端侧行链路非授权频段SL-U上满足OCB要求，从而可以满足未来潜在的多样化应用场景和需求。
可以理解，上述实施例是从网络设备侧描述本申请实施例的资源配置的方法的实现方式。本申请实施例还提出了一种资源配置的方法，下面将从终端设备侧描述该资源配置的方法的实现方式。请参见图7，图7是本申请提供的又一种资源配置的方法的流程图。需要说明的是，本申请实施例的资源配置的方法可以应用于终端设备侧行链路非授权频段，可以由终端设备执行。如图7所示，该资源配置的方法可以包括但不限于如下步骤。
在步骤701中，接收网络设备发送的资源池的配置信息。
其中，在本申请的实施例中，资源池的配置信息指示了对应资源池所配置的梳尺资源块索引的数量及位置；同一个梳尺资源块索引中连续的两个梳尺资源块相隔的资源块数值定为M，M由子载波间隔的大小确定。
网络设备将系统中的梳尺资源块映射到多个资源池的资源池配置信息需要通过一定的方式通知给系统的终端设备。可选的，基于资源池配置，网络设备可以通过指示资源池索引向发送端UE和/或接收端UE指示所调度的资源池资源，用于承载UE的控制信息和/或数据信息，UE也可以在可用的资源池资源上自行选择一个或多个资源池用于控制信息和/或数据信息的承载发送。
可选的，在本申请的实施例中，终端设备在接入网络设备时，可以接收到网络设备发送的资源池的配置信息，根据该资源池的配置信息和资源池与梳尺资源块索引的映射规则，即可确定终端设备所调度的资源池所配置的梳尺资源块索引的数量及位置。其中，针对资源池与梳尺资源块索引的映射规则的介绍可参见本文前述关于该映射规则的描述，在此不再赘述。
通过实施本申请实施例，通过提供一种资源池到梳尺资源块索引之间的映射方式，以实现资源池的资源配置，可以在终端侧行链路非授权频段上满足OCB要求，从而可以满足未来潜在的多样化应用场景和需求。
