Description
本申请要求于2022年4月12日提交中国专利局、申请号为202210380989.8、申请名称为“资源配置方法、装置及设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及通信技术领域,尤其涉及一种资源配置方法、装置及设备。
在网络通信系统中,不同的网络设备之间可以通过工作带宽传输信息。若工作带宽为下行带宽,则可以用于网络设备向终端设备发送无线信号;若工作带宽为上行带宽,则可以用于终端设备向网络设备发送无线信号。
在5G通信系统中,为了满足超低时延的需求,可以引入子带全双工技术,即可以根据频域将工作带宽细分为多个子带,并灵活配置子带的上下行配比。然而,在子带全双工场景下,工作带宽中会同时出现上行子带和下行子带,现有的频域资源配置方式是由低到高的顺序连续映射,且配置周期较长,导致无线信号可能会映射到不可用的子带上,因此资源配置的可靠性差。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请中的“至少一个”指的是一个或多个,“多个”是指两个或两个以上。另外,本申请的“等于”可以与“大于”连用,也可以与“小于”连用。在“等于”与“大于”连用的情况下,采用“大于”的技术方案;在“等于”与“小于”连用的情况下,采用“小于”的技术方案。
图1为本申请实施例提供的一种应用场景的示意图,请参见图1,包括网络设备和多个终端设备。例如,网络设备可以为基站,终端设备可以包括终端设备1、终端设备2、……、终端设备n。
网络设备可以获取无线信号的配置信息,并向终端设备发送配置信息。终端设备接收到配置信息之后,可以根据配置信息,确定无线信号待使用的频域资源。网络设备和终端设备可以在指定的频域资源上进行互相通信,即发送或者接收无线信号。例如,网络设备可以与终端设备1在频域资源1上进行通信、与终端设备2在频域资源2上进行通信、……、与终端设备n在频域资源n上进行通信。
在5G通信系统中,为了满足超低时延的需求,可以引入子带全双工技术,即可以根据频域将工作带宽细分为多个子带,并灵活配置子带的上下行
配比。然而,在子带全双工场景下,工作带宽中会同时出现上行子带和下行子带,现有的频域资源配置方式是由低到高的顺序连续映射,且配置周期较长,导致无线信号有可能会映射到不可用的子带上,因此资源配置的可靠性差。
在本申请实施例中,网络设备可以获取无线信号的配置信息,并向终端设备发送配置信息。终端设备接收到网络设备发送的无线信号的配置信息之后,可以根据配置信息所指示的物理资源块,确定无线信号待使用的频域资源。网络设备和终端设备可以在指定的频域资源上进行通信,避免了无线信号映射到不可用的频域资源上,从而提高了资源配置的可靠性。
下面,通过具体实施例对本申请所示的技术方案进行详细说明。需要说明的是,下面几个实施例可以单独存在,也可以相互结合,对于相同或相似的内容,在不同的实施例中不再重复说明。

和PRB-11可以组成第6组PRB,PRB-12为第7组PRB。
如图4,比特图可以为“1011000”,其中,每个比特用于指示一组PRB。例如,比特图中的第1位为1,可以用于指示PRB-0和PRB-1这一组PRB,表示PRB-0和PRB-1待使用;比特图中的第2位为0,用于指示PRB-2和PRB-3这一组PRB,表示PRB-2和PRB-3没有被占用。比特图中的第一位为最高位,对应频域最低位置,可以按照顺序依次映射。
方式2:配置信息可以通过虚拟资源块(virtual resource block,VRB)表示。
配置信息中可以包括至少一个VRB的标识,VRB的标识用于确定对应的PRB的标识。

图5B为本申请实施例提供的分布式映射的示意图。请参见图5B,包括多个VRB和多个PRB,各个VRB和PRB分别有对应的标识。例如,若有13个VRB,对应的标识可以分别为0、1、2、……、12;若有13个PRB,对应的标识可以分别为0、1、2、……、12。
在分布式的映射方式中,VRB和PRB不是一一对应的,连续的VRB可以映射到不连续的PRB上。如图5B,VRB-3、VRB-4、VRB-5为连续的连续VRB。其中,VRB-3可以用于确定PRB-2,VRB-4可以用于确定PRB-6,VRB-5可以用于确定PRB-10,PRB-2、PRB-6、PRB-10为不连续的PRB。

例如,若配置信息包括VRB-3、VRB-4、VRB-5,且VRB-3可以用于确定PRB-2,VRB-4可以用于确定PRB-6,VRB-5可以用于确定PRB-10,则终端设备可以确定无线信号待使用的频域资源为PRB-2、PRB-6和PRB-10。
在本申请实施例中,网络设备可以获取无线信号的配置信息,并可以向终端设备发送配置信息。终端设备可以根据配置信息所指示的物理资源块,确定无线信号待使用的频域资源。网络设备和终端设备可以在指定的频域资源上进行通信,避免了无线信号映射到不可用的频域资源上,从而提高了资源配置的可靠性。

S604、网络设备在频域资源上向终端设备发送PDSCH。
例如,若确定PRB-0、PRB-1、PRB-2、PRB-3、PRB-8、PRB-9为频域资源,则网络设备可以在该6个指定的PRB上向终端设备发送PDSCH,以使终端设备在该6个指定的PRB上接收PDSCH。
在本申请实施例中,网络设备可以获取下行控制信息,并向终端设备发送下行控制信息。终端设备可以根据下行控制信息中的配置信息所指示的物理资源块,确定无线网络待使用的频域资源,并在待使用的频域资源上接收物理下行共享信道。网络设备和终端设备可以在指定的频域资源上进行通信,避免了物理下行共享信道映射到不可用的频域资源上,从而提高了资源配置的可靠性。
下面,在图2所示实施例的基础上,结合图7,对物理上行共享信道的资源配置方法进行进一步详细说明。图7为本申请实施例提供的物理上行共享信道的资源配置方法的流程示意图。请参见图7,该方法可以包括:

S704、终端设备在频域资源上向网络设备发送PUSCH。
例如,若终端设备将PRB-1、PRB-2确定为频域资源,则终端设备可以在该2个指定的PRB上向网络设备发送PUSCH,以使网络设备可以在该该2个指定的PRB上接收PUSCH。
在本申请实施例中,网络设备可以获取上行控制信息,并向终端设备发送上行控制信息。终端设备可以根据上行控制信息中的配置信息所指示的物理资源块,确定无线信号待使用的频域资源,并在待使用的频域资源上发送物理上行共享信道。网络设备和终端设备可以在指定的频域资源上进行通信,避免了物理上行共享信道映射到不可用的频域资源上,从而提高了资源配置的可靠性。

下面,结合图10A-图10B对映射起始PRB的位置进行说明。
情况1:若第一起始PRB的标识大于或等于第二起始PRB的标识,则将第一起始PRB确定为映射起始PRB。
图10A为本申请实施例提供的一种映射起始PRB的位置示意图。请参见图10A,若配置信息中指示频域映射子带为子带1,且指示有10个PRB,其中,第一起始PRB为PRB-2。则终端设备可以确定子带1中包括15个PRB,且子带1的起始PRB为PRB-0,则终端设备可以将PRB-0确定为第二起始PRB。由于第一起始PRB的标识大于第二起始PRB的标识,则终端设备可以将第一起始PRB,即PRB-2,确定为映射起始PRB。
情况2:若第一起始PRB的标识小于第二起始PRB的标识,则将第二起始PRB确定为映射起始PRB。
图10B为本申请实施例提供的另一种映射起始PRB的位置示意图。
请参见图10B,若配置信息中指示频域映射子带为子带2,且指示有10
个PRB,其中,第一起始PRB为PRB-0。则终端设备可以确定子带2中包括8个PRB,且子带2的起始PRB为PRB-3,则终端设备可以将PRB-3确定为第二起始PRB。由于第一起始PRB的标识小于第二起始PRB的标识,则终端设备可以将第二起始PRB,即PRB-3,确定为映射起始PRB。
S805、终端设备确定剩余PRB。
终端设备可以根据映射起始PRB和频域映射子带的终止PRB,确定剩余PRB,可以包括如下2种情况:
情况1:若频域映射子带为某一下行子带,则根据映射起始PRB和该下行子带的终止PRB,确定剩余PRB。
如图10A中,若频域映射子带为子带1,且映射起始PRB为PRB-2;若子带1的终止PRB为PRB-14,则终端设备可以将子带1中的PRB-2至PRB-14确定为剩余PRB。
情况2:若频域映射子带为多个下行子带,则根据映射起始PRB和多个下行子带的终止PRB,确定剩余PRB。
例如,若频域映射子带包括子带1和子带3,其中,子带3的频域位置低于子带1的频域位置,子带1和子带3均为传输下行信号的子带。若子带3对应的起始PRB至终止PRB为PRB-0至PRB-8,子带1对应的起始PRB至终止PRB为PRB-20至PRB-31。则终端设备可以根据子带3对应的起始PRB确定映射起始PRB,若确定映射起始PRB为PRB-1,则终端设备可以将子带3中的PRB-1至PRB-8、子带1的PRB-20至PRB-31确定为剩余PRB。
S806、终端设备根据映射起始PRB、剩余PRB和第一数量,确定频域资源。
终端设备可以将剩余PRB中用于传输下行信号的PRB的数量确定为第二数量,进一步的,可以根据映射起始PRB、第二数量和第一数量,确定频域资源。具体的,可以包括如下4种情况:
若频域映射子带为某一下行子带,则剩余PRB均为该下行子带中的PRB,则可以包括情况1和情况2,其中,
情况1:若第二数量大于或等于第一数量,则可以根据映射起始PRB和第一数量,在剩余PRB中确定频域资源。
如图10A中,若配置信息中指示的频域映射子带为子带1,且指示有10个PRB,则第一数量为10。若终端设备确定子带1的剩余PRB为PRB-2至PRB-14,其中PRB-2至PRB-14均用于传输下行信号,则对应的第二数量为13。由于第二数量大于第一数量,则终端设备可以在子带1的PRB-2至PRB-14中,将PRB-2至PRB-11的10个PRB确定为频域资源。
情况2:若第二数量小于第一数量,则可以根据映射起始PRB和第二数量,将剩余PRB确定为频域资源。
如图10B中,若配置信息中指示的频域映射子带为子带2,且指示有10个PRB,则第一数量为10。若终端设备确定子带2的剩余PRB为PRB-3至PRB-10,其中PRB-3至PRB-10均用于传输下行信号,则对应的第二数量为8。由于第二数量小于第一数量,则终端设备可以将子带2中的PRB-3至PRB-10,共8个PRB确定为频域资源。
若频域映射子带为多个下行子带,则剩余PRB为多个下行子带中的PRB,则包括情况3和情况4。下面,结合图11A-图11B,对在多个子带中确定频域资源进行说明。
情况3:若多个下行子带中用于传输下行信号的PRB的第二数量大于或者等于第一数量,根据映射起始PRB和第一数量,在剩余PRB中确定频域资源。
图11A为本申请实施例提供的确定频域资源的示意图一。请参见图11A,若工作带宽中包括子带1、子带2和子带3,其中,子带1和子带3为下行子带,子带2为上行子带。若配置信息中指示频域映射子带为子带3和子带1,且包括10个PRB。则终端设备可以确定子带3中剩余PRB为PRB-1至PRB-12,其中PRB-1至PRB-12均用于传输下行信号,共12个PRB;确定子带1中的PRB为PRB-20至PRB-30,其中PRB-20至PRB-30均用于传输下行信号,共11个PRB。其中,子带3的频域位置低于子带1的频域位置。虽然配置信息指示了子带1和子带3,但由于子带3中的传输下行信号的PRB为12个,大于配置信息中指示的10个PRB,且子带3的频域位置低于子带1的频域位置,则终端设备可以将子带3中的PRB-1至PRB-10,共10个剩余PRB确定为频域资源。
情况4:若多个下行子带中用于传输下行信号的PRB的第二数量小于
第一数量,根据映射起始PRB和第一数量,在多个下行子带的PRB中确定频域资源。
图11B为本申请实施例提供的确定频域资源的示意图二。请参见图11B,若工作带宽中包括子带1、子带2和子带3,其中,子带1和子带3为下行子带,子带2为上行子带。若配置信息中指示频域映射子带为子带1和子带3,且包括20个PRB;若终端设备确定子带3中用于传输下行信号的PRB为9个,子带1中用于传输下行信号的PRB为10个,其中,子带3的频域位置低于子带1的频域位置。若终端设备确定子带3中剩余PRB为PRB-1至PRB-9,其中PRB-1至PRB-9均用于传输下行信号,共9个PRB;确定子带1中的PRB为PRB-20至PRB-29,其中PRB-20至PRB-29均用于传输下行信号,共10个PRB,则终端设备可以将子带3中的PRB-1至PRB-9、子带1中的PRB-20至PRB-29,确定为频域资源。由于工作带宽中的子带2用于传输上行信号,则子带2中的PRB不可用,在映射过程中,可以避开子带2。
需要说明的是,在本申请实施例中,频域资源可以用于终端设备接收CSI-RS。
S807、网络设备在频域资源上向终端设备发送CSI-RS。
例如,若确定子带2中PRB-3至PRB-10为频域资源,则网络设备可以在子带2中PRB-3至PRB-10上向终端设备发送CSI-RS,以使终端设备在该子带的PRB-3至PRB-10上接收CSI-RS。
在本申请实施例中,网络设备可以获取无线信号的配置信息,并向终端设备发送配置信息,配置信息中可以包括至少一个PRB中第一起始PRB的标识和至少一个PRB的第一数量。终端设备可以根据配置信息确定频域映射子带的第二起始PRB,进而可以根据第一起始PRB和第二起始PRB确定映射起始PRB。终端设备可以根据映射起始PRB和频域映射子带的终止PRB确定剩余PRB,并在剩余PRB中确定用于传输下行信号的PRB的第二数量,进一步的,可以根据映射起始PRB、第二数量和第一数量,将剩余PRB或在剩余PRB中确定频域资源,并在频域资源上接收下行信道状态信息参考信号。网络设备和终端设备可以在指定的频域资源上进行通信,避免了下行信道状态信息参考信号映射到不可用的频域资源上,从
而提高了资源配置的可靠性。
