Abstract

Description

通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
设备到设备通信(Device-to-Device，D2D)是一种侧行链路(Sidelink，SL)传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，其具有更高的频谱效率以及更低的传输时延。
针对侧行资源池，除了常规时隙(slot)以外，NR新空口(New Radio，NR)用户通用网络(User to Network interface Universal，Uu)口传输系统中，还引入了微时隙(mini-slot)传输或调度。即，网络调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)或物理上行共享信道(Physical Downlink Shared Channel，PDSCH)不是以常规时隙为粒度，而是以常规时隙内的时域符号为粒度，从而可以达到降低时延的目的。
在现有的NR SL系统中，侧行传输或调度都是以常规时隙(slot)为粒度的。然而，当NR SL应用到工业互联网等场景时，对系统的时延具有更高的要求，可以使用基于微时隙的侧行传输方式来满足时延要求。然而，在现有的NR SL系统中，当使用基于微时隙的侧行传输方式时，无法保证微时隙和常规时隙的共存。

如图2所示，在部分网络覆盖侧行通信情况下，部分进行侧行通信的终端位于网络设备的覆盖范围内，位于网络设备的覆盖范围内的终端能够接收到网络设备的配置信令，并根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端，无法接收网络设备的配置信令，此时，网络覆盖范围外的终端将根据预配置(pre-configuration)信息以及位于网络覆盖范围内的终端发送的物理侧行广播信道(Physical Sidelink Broadcast Channel，PSBCH)中携带的信息确定侧行配置，从而进行侧行通信。
如图3所示，在网络覆盖外侧行通信的情况下，所有进行侧行通信的终端均位于网络覆盖范围外，进而所有终端均根据预配置信息确定侧行配置，从而进行侧行通信。
设备到设备通信是一种侧行链路传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，其具有更高的频谱效率以及更低的传输时延。其中，车联网系统采用设备到设备通信的方式，在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)定义了两种传输模式：第一模式和第二模式。
其中，在第一模式中，终端设备的传输资源是由网络设备分配的，终端设备根据终端设备分配的资源在侧行链路上进行数据的发送。网络设备可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。如图1所示，终端设备位于网络覆盖范围内，网络设备为终端分配侧行传输使用的传输资源。
在第一模式中，终端设备在资源池中选取一个资源进行数据的传输。如图3所示，终端设备位于小区覆盖范围外，终端设备在预配置的资源池中自主选取传输资源进行侧行传输。或者，如图1所示，终端设备在网络配置的资源池中自主选取传输资源进行侧行传输。
下面对于NR车用无线通信技术(vehicle to X，V2X)进行说明。
首先，在NR-V2X中，需要支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
其次，在LTE-V2X中，支持广播传输方式，同时也引入了单播和组播的传输方式。图4为本申请实施例提供的一种单播传输的示意图，图5为本申请实施例提供的一种组播传输的示意图，图6为本申请实施例提供的一种广播传输的示意图。对于单播传输，其接收端终端只有一个终端，如图4中，用户设备(User Equipment，UE)1、UE2之间进行单播传输。对于组播传输，其接收端是一个通信组内的所有终端，或者是在一定传输距离内的所有终端，如图5，UE1、UE2、UE3和UE4构成一个通信组，其中UE1发送数据，该组内的其他终端设备都是接收端终端。对于广播传输方式，其接收端是发送端终端周围的任意一个终端，如图6，UE1是发送端终端，其周围的其他终端，UE2-UE6都是接收端终端。
下面对于NR-V2X的系统帧的时隙结构进行说明。
图7为本申请实施例提供的一种时隙结构的示意图，图8为本申请实施例提供的另一种时隙结构的示意图。其中，图7所示的时隙结构中不包括物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)，图8所示的时隙结构中包括PSFCH。
参考图7和图8，在NR-V2X中，物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)在时域上从该时隙的第二个侧行符号开始，占用2个或3个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，在频域上可以占用{10，12，15，20，25}个物理资源块(Orthogonal Frequency Division Multiplexing，PRB)。为了避免终端设备对PSCCH的盲检测，在一个资源池内只允许配置一个PSCCH符号个数和PRB个数。另外，由于子信道为NR-V2X中PSSCH资源分配的最小粒度，PSCCH占用的PRB个数必须小于或等于资源池内一个子信道中包含的PRB个数，以免对物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)资源选择或分配造成额外的限制。PSSCH在时域上也是从该时隙的第二个侧行符号开始，该时隙中的最后一个时域符号为保护间隔(Guard period，GP)符号，其余符号映射PSSCH。该时隙中的第一个侧行符号是第二个侧行符号的重复，通常接收端终端将第一个侧行符号用作自动增益控制(Automatic Gain Control，AGC)符号，该符号上的数据通常不用于数据解调。如图7所示，PSSCH在频域上占据K个子信道，每个子信道包括N个连续的PRB。
当时隙中包含PSFCH信道时，如图8所示，该时隙中倒数第二个和倒数第三个符号用作PSFCH信道传输，在PSFCH信道之前的一个时域符号用作GP符号。
下面对于NR-V2X中的2阶系统控制信息(System Control Information，SCI)机制进行说明。
在NR-V2X中引入2阶SCI，第一阶SCI承载在PSCCH中，用于指示PSSCH的传输资源、预留资源信息、调制与编码策略(Modulation and Coding Scheme，MCS)等级、优先级等信息，第二阶SCI在PSSCH的资源中发送，利用PSSCH的解调参考信号(Demodulation Reference Signal，DMRS)进行解调，用于指示发送端标识、接收端标识、混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)标识、网络设备接口(Network Device Interface，NDI)等用于数据解调的信息。第二阶SCI从PSSCH的第一个DMRS符号开始映射，先频域再时域映射。图9为本申请实施例提供的一种2阶SCI的资源映射图。如图9所示，PSCCH占据3个符号(符号1、2、3)，PSSCH的DMRS占据符号4、11，第二阶SCI从符号4开始映射，在符号4上和DMRS频分复用，第二阶SCI映射到符号4、5、6，第二阶SCI占据的资源大小取决于第二阶SCI的比特数。
下面对于侧行反馈信道进行说明。
在NR-V2X中，为了提高可靠性，引入了侧行反馈信道。示例性的，对于单播传输，发送端终端向接收端终端发送侧行数据(包括PSCCH和PSSCH)，接收端终端向发送端终端发送HARQ反馈信息(包括确认字符(Acknowledge character，ACK)或否认字符(Non Acknowledge character，NACK))，发送端终端根据接收端终端的反馈信息判断是否需要进行重传。其中，HARQ反馈信息承载在侧行反馈信道中，例如PSFCH。
在一些实施例中，可以通过预配置信息或者网络配置信息激活或者去激活侧行反馈。若侧行反馈被激活，则接收端终端接收发送端终端发送的侧行数据，并且根据检测结果向发送端反馈HARQ ACK或者NACK，发送端终端根据接收端的反馈信息决定发送重传数据或者新数据。若侧行反馈被去激活，接收端终端不需要发送反馈信息，发送端终端通常采用盲重传的方式发送数据，例如，发送端终端对每个侧行数据重复发送K次，而不是根据接收端终端反馈信息决定是否需要发送重传数据。
下面对于侧行反馈信道的格式进行说明。
在NR-V2X中，引入了PSFCH，该PSFCH只承载1比特的HARQ-ACK信息，在时域上占据2个时域符号(第二个符号承载侧行反馈信息，第一个符号上的数据是第二个符号上数据的复制，但是该符号用作AGC)，频域上占据1个PRB。图10为本申请实施例提供的一种侧行反馈信道的格式的示意图。如图10所示，给出了在一个时隙中PSFCH、PSCCH和PSSCH所占的时域符号的位置。在一个时隙中，最后一个符号用作GP，倒数第二个符号用于PSFCH传输，倒数第三个符号数据和PSFCH符号的数据相同，用做AGC，倒数第四个符号也用作GP，时隙中的第一个符号用作AGC，该符号上的数据和该时隙中第二个时域符号上的数据相同，PSCCH占据3个时域符号，剩余的符号可用于PSSCH传输。
下面对于侧行资源池时隙配置进行说明。
在NR-V2X中，可以通过下面的方式确定资源池中的时域资源。
在一些实施例中，可以在一个系统帧计数(System Frame Number，SFN)周期或一个直接帧计数(Direct Frame Number，DFN)周期内确定资源池的时域资源，具体地，通过以下方式确定一个SFN周期或一个DFN周期内的哪些时域资源属于资源池。
示例性的，一个SFN周期内包括的时隙总数是10240×2 μ个时隙，其中，参数μ与子载波间隔大小有关。在10240×2 μ个时隙中，去掉同步时隙、下行时隙、特殊时隙、以及预留时隙(reserved subframe)，剩余的时隙重新编号后形成的时隙集合为
Figure PCTCN2021108254-appb-000001
其中，剩余的时隙的个数能够被L bitmap整除，L bitmap表示用于指示资源池配置的比特位图的长度；若一个时隙包括的时域符号Y,Y+1,Y+2,…,Y+X-1中至少有一个时域符号不是被网络的信令(TDD-UL-DL-ConfigCommon)配置为上行符号，则该时隙为特殊时隙；Y和X分别表示sl-StartSymbol和sl-LengthSymbols两个RRC层参数，用于指示资源池配置的比特位图
Figure PCTCN2021108254-appb-000002
周期性的映射至剩余的各个时隙上；比特位的取值为1表示该比特位对应的时隙属于资源池，比特位的取值为0表示该比特位对应的时隙不属于资源池。
一个SFN周期或一个DFN周期包括10240×2 μ个时隙(即10240ms)，同步信号的周期(简称为同步周期)是160ms，在一个同步周期内包括2个同步时隙，因此，在一个SFN周期内共有128个同步时隙。用于指示资源池配置的比特位图的长度是10比特(即L bitmap＝10)，因此需要2个预留时隙(reserved subframe)，剩余时隙的个数是(10240-128-2＝10110)，可以被比特位图的长度10整除，将剩余的时隙重新编号为0，1，2，……，10109，比特位图前3位为1,其余7位为0，即
Figure PCTCN2021108254-appb-000003
由此可知，在剩余时隙中，每10个时隙中的前3个时隙属于资源池，其余的时隙不属于资源池。由于在剩余时隙中需要比特位图重复1011次， 以指示所有的时隙是否属于资源池，而在每个比特位图的周期内有3个时隙属于资源池，因此在一个SFN周期共有3033个时隙属于资源池。
需要说明的是，上述图7-图10中涉及的时隙均为常规时隙。
下面对于微时隙进行说明。
在Rel-15 NR Uu口传输系统中，引入了微时隙(mini-slot)传输或调度，即网络调度的PUSCH或PDSCH不是以时隙为粒度，而是以时隙内的时域符号为粒度，从而可以达到降低时延的目的。
图11为本申请实施例提供的一种微时隙调度示意图。如图11所示，位于时隙头部的PDCCH既可以调度位于同一时隙内的PDSCH(以mini-slot 1作为资源单位)，也可以调度位于时隙尾部的PUSCH(以mini-slot 2作为资源单位)，从而可以在一个时隙内对上下行数据进行快速调度。在NR系统中，支持以{2，4，7}个时域符号为时域调度粒度的微时隙调度。
在现有的NR SL系统中，侧行传输或调度都是以常规时隙(slot)为粒度的。然而，当NR SL应用到工业互联网等场景时，对系统的时延具有更高的要求，可以使用基于微时隙的侧行传输方式来满足时延要求。然而，在现有的NR SL系统中，当使用基于微时隙的侧行传输方式时，无法保证微时隙和常规时隙的共存。
为解决上述问题，本申请实施例提供一种通信方法及装置，终端设备在侧行链路传输时根据微时隙和常规时隙的配置方式确定资源池。通过该方式，终端设备根据微时隙和常规时隙的配置方式来确定资源池，从而保证常规时隙和微时隙的共存。
下面对于本申请的应用场景进行举例说明。
图12为本申请实施例提供的一种通信方法的场景示意图。如图12所示，网络设备102向终端设备发送配置信息，终端设备101在获取到配置信息后，确定微时隙和常规时隙的配置方式，从而在侧行链路传输时根据微时隙和常规时隙的配置方式确定资源池。
其中，终端设备101可以包括但不限于卫星或蜂窝电话、可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
网络设备102可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备102可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
下面以终端设备和网络设备为例，以具体地实施例对本申请实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图13为本申请实施例提供的一种通信方法的流程示意图。本申请实施例涉及的是终端设备如何确定资源池的过程。如图13所示，该方法包括：
S201、终端设备获取配置信息。
其中，该配置信息中包含有微时隙和常规时隙的配置方式。资源池用于侧行链路传输，该侧行链路传输为至少基于微时隙的侧行链路传输。
在本申请实施例中，在至少基于微时隙的侧行链路传输中，当终端设备需要确定资源池前，可以从网络设备发送的配置信息中，确定微时隙和常规时隙的配置方式。
应理解，本申请实施例对于如何获取配置信息不做限制，在一些实施例中，配置信息可以由网络设备配置，或者可以预配置，或者可以由标准定义。
应理解，本申请实施例对于微时隙和常规时隙的配置方式不做限制，示例性的，可以包括微时隙和常规时隙存在于不同的时分的资源池、微时隙和常规时隙存在于不同的频分的资源池以及微时隙和常规 时隙存在于同一个资源池三种方式。
下面针对上述提供的三种微时隙和常规时隙的配置方式进行分别说明。
在第一种配置方式中，微时隙和常规时隙存在于不同的时分的资源池，即，微时隙和常规时隙存在于不同的资源池内，且不同资源池占用的时域资源不重叠。若在一个载波上，一个资源池内包含的时域资源的粒度可以为微时隙，相应的，配置信息中可以包括第一指示信息，该第一指示信息用于指示资源池的最小时域粒度。
示例性的，第一指示信息指示的资源池的最小时域粒度可以为14个符号或7个符号。若第一指示信息指示为14个符号，则表明该资源池的最小时域粒度为常规时隙，若第一指示信息指示为7个符号，则表示该资源池的最小时域粒度为微时隙。
在一些实施例中，一个载波上配置有以微时隙为最小时域粒度的资源池，若常规时隙中部分符号被配置为以微时隙为最小资源粒度的资源池，则常规时隙中的剩余符号同样被配置为以微时隙为最小资源粒度的资源池。
示例性的，若一个时隙的前7个符号被配置为以微时隙为最小时间粒度的资源A，则剩余的7个符号应被配置为以微时隙为最小时间粒度的资源池B。其中，资源池A和资源池B可以为同一个资源池，也可以为不同的资源池。
应理解，在本申请实施例中，配置信息中还可以指示微时隙的位置。相应的，配置信息中还包括第二指示信息和第三指示信息，第二指示信息用于指示属于资源池的微时隙所在的常规时隙的位置，第三指示信息用于指示属于资源池的微时隙在常规时隙中的位置。
本申请实施例对于如何确定微时隙的位置不做限制。在一些实施例中，第二指示信息包括位图信息，第三指示信息包括索引值，位图信息用于确定属于资源池的微时隙所在的时隙的位置，索引值用于指示该时隙内的哪一个微时隙属于资源池，通过位图信息和索引值可以确定微时隙的位置。示例性的，图14为本申请实施例提供的一种微时隙的位置示意图，如图14所示，一个长度为10的比特位图指示每10个时隙内的第0，1，4，5，8和9号时隙内包含了属于资源池的微时隙，随后，通过索引值1指示比特位图指示的时隙中的第二个微时隙属于资源池。
在另一些实施例中，第二指示信息包括位图信息，第三指示信息包括多个定位参数，多个定位参数包括属于资源池的微时隙在常规时隙中的起点参数和属于资源池的微时隙的长度参数。位图信息用于确定属于资源池的微时隙所在的时隙的位置，多个定位参数用于指示该时隙内的哪一个微时隙属于资源池，通过位图信息和多个定位参数可以确定微时隙的位置。
在第二种配置方式中，微时隙和常规时隙存在于不同的频分的资源池。在第三种配置方式中，微时隙和常规时隙存在于同一个资源池。针对第二种配置方式和第三种配置方式，配置信息中还包括微时隙的配置信息。
图15为本申请实施例提供的一种微时隙时频位置示意图。如图15所示，在第二种配置方式和第三种配置方式中，微时隙的配置信息包括微时隙的长度为两个字符，以及微时隙位于一个侧行时隙的倒数第三和倒数第二个符号上。优选的，若一个侧行时隙的倒数第3和倒数第2个符号上存在PSFCH，则PSFCH所占的PRB和微时隙所占的PRB不重叠。
应理解，侧行时隙是指可以用于侧行发送的时隙。
在一些实施例中，在第二种配置方式和第三种配置方式中，微时隙的配置信息还包括在微时隙发送的物理侧行控制信道和物理侧行共享信道的自动增益控制符号位于下一个侧行时隙的倒数第四个符号上。在微时隙发送的物理侧行控制信道和物理侧行共享信道在倒数第四个符号内的发送时间不晚于预设时刻T。其中，预设时刻T为倒数第四个符号的结束时刻。
需要说明的是，T为预设值。示例性的，T等于半个符号的长度。终端设备在T发送的信号可以是倒数第3个符号上开始T时间内发送信号的，倒数第三个符号上最后T时间内发送的信号的重复。示例性的，如图14所示，可以将第10个符号的最后半个符号作为微时隙的AGC符号。
优选的，在第二种配置方式和第三种配置方式中，在微时隙发送的物理侧行控制信道占用两个符号，且占用预设个数的物理资源块。
其中，被PSCCH所调度的PSSCH所占用的起始PRB和PSCCH占用的最后一个PRB相邻。示例性的，在微时隙发送的PSSCH的DMRS位于微时隙的第一个符号。
其中，本申请实施例对于预设个数不做限制，示例性的，可以由标准定义、网络配置或预配置。
在一些实施例中，在第二种配置方式和第三种配置方式中，微时隙的配置信息还包括在微时隙发送的物理侧行控制信道和物理侧行共享信道的自动增益控制符号位于侧行时隙的倒数第三个符号上(微时隙的第一个符号)，且占用整个倒数第三个符号。此时，AGC符号上发送的信号是微时隙第二个符号 上发送信号的重复。在这种情况下，微时隙发送的PSCCH占用微时隙的第二个符号上特定数目的PRB，被调度的PSSCH的其实PRB和PSCCH的最后一个PRB相邻，PSSCH的DMRS也位于微时隙的第二个符号。
相较于第二种配置方式，第三种配置方式还存在一些区别的配置策略。
在一些实施例中，在第三种配置方式中，一个常规时隙内的微时隙和该常规时隙属于同一个资源池，则该常规时隙中的微时隙以外的符号上发送的物理侧行控制信道用于指示预留微时隙上的资源用于同一个传输块的重传或另外一个传输块的新传。需要说明的是，在相反的情况下，同样成立。
优选的，微时隙内的子信道(sub-channel)包含的PRB个数大于常规时隙内一个子信道包含的PRB个数。示例性的，如图14所示，若常规时隙内的第0到第9个符号均可以用于PSCCH或PSSCH发送，则微时隙内一个子信道包含的PRB个数可以为常规时隙内一个子信道包含的PRB的5倍。通过该方式，可以保证一个TB在常规时隙和微时隙上发送时码率接近。
在一些实施例中，在第三种配置方式中，对于在微时隙上发送的PSSCH，且PSSCH占用的子信道个数为预设数量，则终端和接收终端均根据常规时隙上的配置确定第二阶SCI占用的RE数。相应的，配置信息中还包括常规时隙的配置信息，常规时隙的配置信息用于确定在微时隙上发送物理侧行共享信道且物理侧行共享信道占用的子信道数量为预设数量时，第二阶侧行链路控制信息占用的资源数。则常规时隙的配置信息包括常规时隙上预设数量的子信道内可用于物理侧行共享信道发送的资源数以及常规时隙内用于一个物理侧行控制信道以及物理侧行控制信道的解调参考信号发送的资源数。
相应的，若常规时隙的配置信息还用于确定传输块的大小，则常规时隙的配置信息包括常规时隙上的解调参考信号配置，常规时隙上的侧行符号数配置，常规时隙上的物理侧行共享信道的解调参考信号配置，一个常规时隙上预设数量的子信道内可用于物理侧行共享信道发送的物理资源块的个数。
在一些实施例中，常规时隙可以预留微时隙内的资源，或者微时隙内的资源可以预留常规时隙内的资源。相应的，侧行链路传输中用于指示预留资源的侧行链路控制信息中包括第四指示信息，该第四指示信息用于指示预留的资源位于微时隙或位于常规时隙。
在一些实施例中，侧行链路传输中下行链路控制信息中还包括第五指示信息，第五指示信息用于指示当前调度的是微时隙或常规时隙。
S202、终端设备根据配置信息确定资源池。
在本步骤中，终端设备在获取网络设备发送的配置信息后，可以在侧行链路传输时根据配置信息确定资源池。
需要说明的是，本申请实施例对于如何确定资源池不在赘述，可以基于步骤S201中的配置方式进行确定。
在本申请中，提供了一种微时隙和常规时隙在同一个载波上共存的通信方法，通过本申请提出的方法，微时隙可以和常规时隙分属不同的时分的资源池，或者，微时隙可以和常规时隙分属不同的频分的资源池，或者微时隙可以和常规时隙配置为相同的资源池。如果微时隙和常规时隙分属不同的频分资源池或属于统一资源池，则微时隙所站用的资源位于PSFCH符号位置所在位置。通过该方式，可以在一个载波上支持常规时隙的同时进一步支持微时隙，从而降低侧行传输的时延，增加一个时隙内侧行传输的机会。
本申请实施例提供的通信方法，终端设备在侧行链路传输时根据配置信息确定资源池，该配置信息中包含有微时隙和常规时隙的配置方式。通过该方式，终端设备根据微时隙和常规时隙的配置方式来确定资源池，从而保证常规时隙和微时隙的共存。
在上述实施例的基础上，微时隙和常规时隙的配置方式可以从预配置信息中获取，也可从网络设备发送的配置信息中获取。下面提供一种网络设备为终端设备提供配置信息从而使终端设备确定资源池的方式。图16为本申请实施例提供的一种通信方法的信令交互图。如图16所示，该方法包括：
