本申请主张在2018年12月7日在中国提交的中国专利申请号No.201811497481.6的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种资源池配置方法、装置及设备。
背景技术
3GPP Release 14阶段定义了长期演进(Long Term Evolution,LTE)-车联网(Vehicle to everything,V2X)的协议,包括两种通信方式,分别为终端之间直通链路通信方式,以及终端与基站之间的上/下行链路通信方式。其中,终端之间直通链路通信方式包括2种发送模式,分别是直通链路发送模式3和直通链路发送模式4。直通链路发送模式3为基站为终端调度分配资源,直通链路发送模式4为UE自主选择资源。
直通链路通信方式下,车载终端设备或者终端类型的路侧设备(Road Side Unit,RSU),均通过预配置方式或者网络配置方式(包括基站广播的系统信息或者基站为无线资源控制(Radio Resource Control,RRC)连接态UE/UE类型RSU发送RRC连接重配置消息)获取可用的发送资源池信息和接收资源池信息。
然而,3GPP Release 14接入层协议中,没有对车载终端设备和终端类型RSU进行区分,统称为终端设备(User Equipment,UE),因此车载终端设备和终端类型RSU均执行相同的接入层(各层)过程、获取相同的RRC层预配置信息或者网络配置信息。3GPP Release 15的LTE V2X接入层协议,对载波聚合、高阶调制、时延缩减、直通链路发送模式3和直通链路发送模式4资源池共享等技术方向进行技术增强,但未对车载终端设备和终端类型RSU的接入层(各层)过程、RRC层预配置信息或者网络配置信息进行区分。
但在LTE-V2X系统实际部署中,由于监管机构对LTE-V2X直连通信的 频谱分配及要求中、会对车载终端设备和终端类型RSU进行差异化管理,例如,中华人民共和国工业和信息化部下发的《车联网(智能网联汽车)直连通信使用5905-5925MHz频段管理规定(暂行)》附件“车联网(智能网联汽车)直连通信无线电设备技术要求”中对等效全向辐射功率(Equivalent Isotropic Radiated Power,EIRP)作出规定,车载或便携无线电设备为26dBm,路边无线电设备(即RSU):29dBm,两类设备均工作在5905MHz-5925MHz的载波上。
针对上述规定,如果车载或便携无线电设备工作在相同的发送资源池内进行LTE-V2X业务发送,则RSU(工作在直连通信频段的一般为终端类型RSU)的EIRP将比车载终端设备和便携无线电设备的EIRP高出3dB,RSU发送的业务包对车载终端设备和便携无线电设备发送的业务包造成更强的干扰,不利于造成车载终端设备和便携无线电设备发送业务的可靠性降低。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,本公开的一些实施例的一种资源池配置方法,应用于第一设备,包括:
步骤101,接收第二设备发送的配置信息,其中所述配置信息至少包括资源池配置信息,所述资源池配置信息用于指示资源池参数,所述第一设备的设备类型包括:车载终端设备和路侧设备,且所述资源池参数是与所述设备类型对应的。
通过步骤101,第一设备在接收到第二设备发送的配置信息后,就能够获知该配置信息中的资源池配置信息。由于该资源池配置信息会用于指示资源池参数,且该资源池参数是与设备类型对应的,则便于第一设备针对自身的设备类型有效鉴别和确定第二设备为其配置的资源池参数,达到降低干扰的目的,提升了业务可靠性。
其中,所述配置信息为广播系统信息或单播配置信息。
应该知道的是,该实施例中,可选地,第一设备是车载终端设备或路侧设备(终端类型RSU),第二设备是长期演进LTE基站或者新空口(New Radio,NR)基站。所以,LTE基站或者NR基站广播发送系统信息(广播系统信息)或单播配置信息进行资源池配置或者重配置。
可选地,所述资源池配置信息包括:
资源池参数;
或者
资源池参数,以及以下至少一种:
与发送资源池参数对应的设备类型标识,
与接收资源池参数对应的设备类型标识;
或者
资源池参数,以及以下至少一种:
与设备类型对应的发送资源池标识;
与设备类型对应的接收资源池标识;
或者
资源池参数,以及以下至少一种:
发送资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息;
接收资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息;
其中,所述资源池参数包括发送资源池参数和/或接收资源池参数。
如此,资源池配置信息可结合具体包括的信息项,使得第一设备了解到第二设备为其配置的资源池参数。当然,该资源池配置信息包括的信息不限 于上述内容,还包括配置的用于行人手持设备(便携无线电设备)的资源池参数。当然,该资源池参数是包括至少一个参数的参数集合,即资源池的配置参数。
以基站广播的系统信息(System Information Block,SIB)21为例,可扩展相关技术中的系统信息的元素,增加信息元素i2x-CommTxPoolNormalCommon-r14,用于指示终端类型RSU使用的常规发送资源池,原有的信息元素v2x-CommTxPoolNormalCommon-r14用于指示车载终端设备使用的常规发送资源池。此时,i2x-CommTxPoolNormalCommon-r14可视为终端类型RSU使用的常规发送资源池标识,v2x-CommTxPoolNormalCommon-r14可视为车载终端设备使用的常规发送资源标识。具体地,扩展后的SIB21信息元素如下:
Figure PCTCN2019121960-appb-000001
Figure PCTCN2019121960-appb-000002
当然,在上述扩展后的SIB21信息元素中,信息元素i2x-CommTxPoolNormalCommon-r14对应于直通链路发送资源池的列表SL-CommTxPoolListV2X-r14中的至少一套资源池配置参数SL-CommResourcePoolV2X-r14,指示的参数为当前协议中SL-CommResourcePoolV2X-r14包含的具体参数。
而对于增加的用于指示设备类型的设备类型标识,同样以基站广播的系统信息SIB21为例,一方面,可扩展SL-CommResourcePoolV2X-r14包含的具体参数,如下所示:
Figure PCTCN2019121960-appb-000003
Figure PCTCN2019121960-appb-000004
当然,如果未配置设备类型标识,在发送资源池配置参数集合对应于信息元素v2x-CommTxPoolNormalCommon-r14,则可同时用于车载终端设备和终端类型RSU;在发送资源池配置参数集合对应于信息元素p2x-CommTxPoolNormalCommon-r14,则用于行人手持终端设备(便携无线电设备)。
另一方面,增加的设备类型标识还可通过扩展相关技术中的系统信息的元素实现,用于区分当前系统消息用于指示车载终端设备配置还是终端类型RSU的配置。该实施例中,设备类型标识仅用于区分本系统消息中信息元素v2x-CommTxPoolNormalCommon-r14用于车载终端设备还是终端类型RSU的配置,具体如下所示:
Figure PCTCN2019121960-appb-000005
Figure PCTCN2019121960-appb-000006
并且,在系统信息中如果未配置设备类型标识,信息元素v2x-CommTxPoolNormalCommon-r14,则可同时用于车载终端设备和终端类型RSU;信息元素p2x-CommTxPoolNormalCommon-r14,则用于行人手持终端设备(便携无线电设备)。
另外,还可使用当前的系统信息仅用于对车载终端设备进行配置,而增加系统信息类型,专用于指示为终端类型RSU进行配置。此时,系统信息类型可视为设备类型标识。例如,增加系统信息SIB27,其信息元素如下所示:
Figure PCTCN2019121960-appb-000007
在SIB27中,信息元素i2x-CommTxPoolNormalCommon-r14用于终端类型RSU。当然,反之亦然,将当前的系统信息仅用于对终端类型RSU进行配置,而增加系统信息类型,专用于指示为车载终端设备进行配置,在此不再赘述。
此外,该实施例中,资源池配置信息中多个资源池参数是顺序排列的。若第一设备和第二设备之间系统预定义了发送资源池参数索引(一组发送资源池参数设置有唯一的索引)与车载终端设备和/或路侧设备的对应关系(发送资源池参数索引与设备类型对应的映射关系信息),或者,发送资源池消息元素在系统信息中排序的序号与车载终端设备和/或路侧设备的对应关系(发送资源池参数序号与设备类型对应的映射关系信息)。
如,预定义了发送资源池参数序号为第1,2,…,N的发送资源池参数集合所指示的发送资源池参数为车载终端设备使用的发送资源池参数,其中,N为正整数,1≤N<maxSL-V2X-TxPool-r14;则发送资源池参数序号为第N+1,……,maxSL-V2X-TxPool-r14的发送资源池参数集合所指示的发送资源池参数为路侧设备使用的发送资源池参数。因此,当第一设备接收的资源池配置信息中发送资源池参数,可确定第二设备配置的用于车载终端设备使用的发送资源池参数集合是序号为第1,2,…,N的发送资源池参数集合,第二设备配置的用于路侧设备使用的发送资源池参数是序号为第N+1,……,maxSL-V2X-TxPool-r14的发送资源池参数集合所指示的发送资源池参数。
或者,预定义了发送资源池参数序号为第1,2,…,N的发送资源池参数集合所指示的发送资源池参数为路侧设备使用的发送资源池参数,其中,N为正整数,1≤N<maxSL-V2X-TxPool-r14;则发送资源池参数序号为第N+1,……,maxSL-V2X-TxPool-r14的发送资源池参数集合所指示的发送资源池参数为车载终端设备使用的发送资源池参数。
或者,预定义发送资源池参数序号为奇数的发送资源池参数集合所指示的发送资源池参数为车载终端设备使用的发送资源池参数;则发送资源池参数序号为偶数的发送资源池参数集合所指示的发送资源池参数为路侧设备使用的发送资源池参数。
或者,预定义发送资源池参数序号为奇数的发送资源池参数集合所指示 的发送资源池参数为路侧设备使用的发送资源池参数;则发送资源池参数序号为偶数的发送资源池参数集合所指示的发送资源池参数为车载终端设备使用的发送资源池参数。
可选地,在实际配置的发送资源池参数集合数量不能满足发送资源池索引(或者序号)指示的需要,则配置全部采用缺省值指示的发送资源池参数在对应索引或者序号上,在系统信息中发送。例如:预定义发送资源池参数序号为奇数的发送资源池参数集合所指示的发送资源池参数为车载终端设备使用的发送资源池参数;则发送资源池参数序号为偶数的发送资源池参数集合所指示的发送资源池参数为路侧设备使用的发送资源池参数。此时,基站为车载终端设备配置1组发送资源池参数A,为路侧设备配置2组发送资源池参数B和C;则将发送资源池序号为1的一组发送资源池参数配置为发送资源池参数A,发送资源池序号为2和4的两组发送资源池参数配置为发送资源池参数B和C,而发送资源池序号为3的发送资源池参数集合配置中所有参数为缺省值。
该实施例中,若未预定义资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息,为便于用户针对设备类型对配置的资源池参数识别,会在资源池配置信息中增加资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息。
可选地,资源池参数与设备类型对应的映射关系信息具体由资源池参数索引与设备类型的对应关系列表,或者,资源池参数序号与设备类型的对应关系列表实现。例如,对应关系列表中奇数(或者偶数)序号的资源池参数配置给车载终端设备,对应的偶数(或者奇数)序号的资源池参数配置给路侧设备;或者部分连续的序号的资源池参数配置给车载终端设备,另一部分(可交叠或者不交叠)的连续序号的资源池参数配置给路侧设备;或者灵活配置部分序号的资源池参数给车载终端设备,另一部分(可交叠或者不交叠)的序号的资源池参数配置给路侧设备。
还应该知道的是,在该实施例中,在接收第二设备发送的配置信息之后,还包括:
根据所述配置信息中的资源池配置信息,确定所述第一设备的目标资源 池参数,所述目标资源池参数包括目标发送资源池参数和/或目标接收资源池参数。
可选地,根据所述配置信息中的资源池配置信息,确定所述第一设备的目标资源池参数,包括:
根据所述资源池配置信息,由所述第一设备的设备类型确定所述第二设备为所述第一设备配置的当前资源池参数;
直接判断所述当前资源池参数是否为所述目标资源池参数;或者
将所述当前资源池参数与预配置资源池参数比对,在比对结果满足预设条件的情况下,确定所述当前资源池参数为所述目标资源池参数。
这里,首先会根据源池配置信息,由第一设备的设备类型确定第二设备为第一设备配置的当前资源池参数。可选地,根据所述资源池配置信息,由所述第一设备的设备类型确定所述第二设备为所述第一设备配置的当前资源池参数包括:
通过资源池参数,以及与资源池参数对应的设备类型标识确定当前资源池参数;或者
通过资源池参数,以及与设备类型对应的资源池标识确定当前资源池参数;或者
通过资源池参数,以及资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息确定当前资源池参数;或者
通过资源池参数,以及资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息确定当前资源池参数。
第一设备接收资源池配置信息,由其信息项进行判断,将用于第一设备所述设备类型通信的发送资源池参数确定为第二设备为第一设备配置的当前资源池参数。例如,车载终端设备U1接收配置信息后,对其中资源池配置信息的信息项进行判断,将标记为用于车载终端设备通信的发送资源池参数确定为基站为U1配置的当前发送资源池参数。
具体的判断可由:资源池参数以及与资源池参数对应的设备类型标识;资源池参数以及与设备类型对应的资源池标识;资源池参数,以及资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息;资源池 参数,以及资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息实现。例如,车载终端设备接收系统信息后,对资源池配置信息的信息项进行判断,将标记为v2x-CommTxPoolNormalCommon-r14的发送资源池参数,作为车载终端设备的当前发送资源池参数;或者车载终端设备接收系统信息后,对资源池配置信息的信息项进行判断,将设备类型标识为车载终端设备(如destinationUEType取值为vue)的发送资源池参数,作为车载终端设备的当前发送资源池参数。路侧设备接收系统信息后,对资源池配置信息的信息项进行判断,将标记为i2x-CommTxPoolNormalCommon-r14的发送资源池参数,作为路侧设备的当前发送资源池参数;或者路侧设备接收系统信息后,对资源池配置信息的信息项进行判断,将设备类型标识为路侧设备(如destinationUEType取值为ue-type-rsu)的发送资源池参数,作为路侧设备的当前发送资源池参数。
之后,可将直接将所确定的当前资源池参数作为目标资源池参数,即第一设备自身使用的资源池参数。如,将上例中的当前发送资源池参数直接作为设备自身使用的发送资源池参数。又或者,对于第一设备具有预配置资源池参数的情况,可将所确定的当前资源池参数与预配置资源池参数比对,在比对结果满足预设条件的情况下,确定所确定的当前资源池参数为目标资源池参数。其中,因资源池参数分为发送资源池参数和接收资源池参数,比对时,则是将当前资源池参数中的发送资源池参数与预配置资源池参数中的发送资源池参数比对,当前资源池参数中的接收资源池参数与预配置资源池参数中的接收资源池参数比对。
可选地,所述预设条件,包括以下至少一种:
发送资源池的时域资源参数中资源池位图bitmap长度相同和/或资源池bitmap的取值相同;
发送资源池的频域资源以下参数全部相同,包括:
物理直通链路控制信道(Physical Sidelink Control Channel,PSCCH)和物理旁路共享信道(Physical Sidelink Shared Channel,PSSCH)频域资源的关联方式;
子信道的大小;
子信道的数量;和
子信道起始资源块(Resource block,RB)索引。
这样,第一设备可通过所确定的当前资源池参数与预配置资源池参数中发送资源池的时域资源参数中资源池bitmap长度相同和/或资源池bitmap的取值相同;和/或发送资源池的频域资源预设参数全部相同,确定该比对结果满足预设条件,将该当前资源池参数作为目标资源池参数。其中预设参数包括:PSCCH和PSSCH频域资源的关联方式、子信道的大小(即一个子信道包含的RB数)、子信道的数量和子信道起始RB索引。
另外,对应于PSCCH和PSSCH频域资源的具体关联方式,仅当PSCCH和PSSCH频域资源的关联方式为非邻带方式,才需要指示PSCCH资源池的起始RB,因此,可选地,所述频域资源的参数还包括:
PSCCH资源池的起始RB。
如此,当PSCCH和PSSCH频域资源的关联方式为非邻带方式,配置包括PSCCH资源池的起始RB的信息项时,发送资源池的频域资源预设参数全部相同,预设参数还要包括PSCCH资源池的起始RB,也就是比对时需要比对当前资源池参数与预配置资源池参数中PSCCH资源池的起始RB是否相同。
该实施例中,比对需要基于相同载波,如果部署场景或系统可使用的频谱仅为单载波,则不需进行载波相同的判断。确定相同载波的具体方式包括:
载波所在频率、带宽、时分双工(Time Division Duplexing,TDD)配置相同;或者
载波所在频率、带宽、TDD配置以及同步源优先级配置均相同。
对于预设条件1:发送资源池的时域资源参数中资源池bitmap长度相同和/或资源池bitmap的取值相同,以系统可使用的频谱为20MHz单载波为例:
1)车载终端设备的预配置参数中包含一个发送资源池,其时域资源参数中的时域资源池的bitmap长度为100;车载终端设备获得的系统信息,其中包含两个发送资源池的配置参数:发送资源池1,时域资源参数中的时域资源池的bitmap长度为100;发送资源池2,时域资源参数中的时域资源池的bitmap长度为20;则对于该车载终端设备,系统信息中发送资源池1满足预设条件 1,发送资源池2满足预设条件1,将发送资源池1作为该车载终端设备自身使用的发送资源池。
2)路侧设备的预配置参数中包含一个发送资源池,其时域资源参数中的时域资源池的bitmap长度为100;路侧设备获得的系统信息,其中包含两个发送资源池的配置参数:发送资源池1,时域资源参数中的时域资源池的bitmap长度为100;发送资源池2,时域资源参数中的时域资源池的bitmap长度为20;则对于该路侧设备,系统信息中发送资源池1满足预设条件1,发送资源池2满足预设条件1,将发送资源池1作为该路侧设备自身使用的发送资源池。
3)车载终端设备的预配置参数中包含一个发送资源池,其时域资源参数中的时域资源池bitmap取值为:
0x1111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111;

发送资源池2,时域资源参数中的时域资源池bitmap取值为:
0x0101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101;
则对于该车载终端设备,系统信息中发送资源池1满足预设条件1,发送资源池2满足预设条件1,将发送资源池1作为该车载终端设备自身使用的发送资源池。
4)路侧设备的预配置参数中包含一个发送资源池,其时域资源参数中的时域资源池bitmap取值为:
0x1111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111;
路侧设备获得的系统信息,其中包含两个发送资源池的配置参数:发送资源池1,时域资源参数中的时域资源池bitmap取值为:
0x1111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111;
发送资源池2,时域资源参数中的时域资源池bitmap取值为:
0x0101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101;
则对于该路侧设备,系统信息中发送资源池1满足预设条件1,发送资源池2满足预设条件1,将发送资源池1作为该路侧设备自身使用的发送资源池。
对于预设条件2,发送资源池的频域资源以下参数全部相同,包括:
PSCCH和PSSCH频域资源的关联方式;
子信道的大小;
子信道的数量;
子信道起始RB索引;
PSCCH资源池的起始RB(配置包括PSCCH资源池的起始RB的信息项)。,同样以系统可使用的频谱为20MHz单载波为例:
车载终端设备的预配置参数中包含一个发送资源池的配置参数,其频域资源参数为:
PSCCH和PSSCH频域资源的关联方式:
-参数adjacencyPSCCH-PSSCH取值为True;
子信道的大小:
-参数sizeSubchannel取值为10;
子信道的数量:
-参数numSubchannel取值为5;
子信道起始RB索引:
-参数startRB-Subchannel取值为0;
PSCCH资源池的起始RB(startRB-PSCCH-Pool-r14)未配置。
路侧设备的预配置参数中包含一个发送资源池的配置参数,其频域资源参数为:
PSCCH和PSSCH频域资源的关联方式:
-参数adjacencyPSCCH-PSSCH取值为True;
子信道的大小:
-参数sizeSubchannel取值为10;
子信道的数量:
-参数numSubchannel取值为5;
子信道起始RB索引:
-参数startRB-Subchannel取值为50;
PSCCH资源池的起始RB(startRB-PSCCH-Pool-r14)未配置。
车载终端设备、路侧设备获得相同的系统信息,其中包含两个发送资源池的配置参数:
发送资源池1:
PSCCH和PSSCH频域资源的关联方式:

子信道起始RB索引;
-参数startRB-Subchannel取值为50;
PSCCH资源池的起始RB(startRB-PSCCH-Pool-r14)未配置。
则对于车载终端设备:系统信息中,发送资源池1满足预设条件2,发送资源池2不满足预设条件2,将发送资源池1作为该车载终端设备自身使用的发送资源池。对于路侧设备,系统信息中,发送资源池2满足预设条件2,发送资源池1不满足预设条件2,将发送资源池2作为该路侧设备自身使用的发送资源池。
在该实施例中,可选地,所述资源池配置信息中多个资源池参数是基于预定义的资源池参数与设备类型之间的对应关系排序或者确定索引的;
在根据所述配置信息中的资源池配置信息,确定所述第一设备的目标资源池参数之前,还包括:
获取预定义的资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息。
这样,对于基于预定义的资源池参数与设备类型之间的对应关系排序或者确定索引的多个资源池参数,要确定第一设备的目标资源池参数,需要了解预定义的资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系,以便准确地获知第一设备的目标资源池参数。
综上所述,本公开的一些实施例的资源池配置方法,在接收到第二设备发送的配置信息后,就能够获知该配置信息中的资源池配置信息。由于该资源池配置信息会用于指示资源池参数,且该资源池参数是与设备类型对应的,则便于第一设备针对自身的设备类型有效鉴别和确定第二设备为其配置的资源池参数,达到降低干扰的目的,提升了业务可靠性。
如图2所示,本公开的实施例的种资源池配置方法,应用于第二设备,包括:
步骤201,发送配置信息至第一设备,其中所述配置信息至少包括资源池配置信息,所述资源池配置信息用于指示资源池参数,所述第一设备的设备类型包括:车载终端设备和路侧设备,且所述资源池参数是与所述设备类型对应的。
通过步骤201,第二设备会发送配置信息至第一设备,以使第一设备能够接收该配置信息,获知该配置信息中的资源池配置信息。由于该资源池配置 信息会用于指示资源池参数,且该资源池参数是与设备类型对应的,则便于第一设备针对自身的设备类型有效鉴别和确定第二设备为其配置的资源池参数,达到降低干扰的目的,提升了业务可靠性。
其中,所述配置信息为广播系统信息或单播配置信息。
可选地,第一设备是车载终端设备或路侧设备(终端类型RSU),第二设备是LTE基站或者NR基站。所以,LTE基站或者NR基站广播发送系统信息(广播系统信息)或单播配置信息进行资源池配置或者重配置。
可选地,所述资源池配置信息包括:
资源池参数;
或者
资源池参数,以及以下至少一种:
与发送资源池参数对应的设备类型标识,
与接收资源池参数对应的设备类型标识;
或者
资源池参数,以及以下至少一种:
与设备类型对应的发送资源池标识;
与设备类型对应的接收资源池标识;
或者
资源池参数,以及以下至少一种:
发送资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息;
接收资源池参数在配置信息中的索引或者序号、与设备类型对应的映射关系信息;
其中,所述资源池参数包括发送资源池参数和/或接收资源池参数。
可选地,所述资源池配置信息中多个资源池参数是基于预定义的资源池参数与设备类型之间的对应关系排序或者确定索引的。
如此,资源池配置信息可结合具体包括的信息项,使得第一设备了解到第二设备为其配置的资源池参数。当然,该资源池配置信息包括的信息不限于上述内容,还包括配置的用于行人手持设备(便携无线电设备)的资源池 参数。当然,该资源池参数是包括至少一个参数的参数集合,即资源池的配置参数。
