下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的资源调度方法、装置、终端、网络侧设备及介质进行详细地说明。
目前,NR接入网可以将gNB拆分成集中单元gNB-CU和分布单元gNB-DU,并通过F1接口连接。图2示出了CU-DU的架构图,如图2所示,一个gNB仅包含一个CU,且包含两个DU(实际实现中可包含一个或多个DU)。其中,一个DU包含至少一个小区(即cell);CU包含分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)及以上的协议栈,DU包含PDCP以下的协议栈,例如,无线链路层控制协议(Radio Link Control,RLC)、多路访问控制(Multiple Access Control,MAC)协议和物理层(Physical,PHY)协议;在控制面,CU包含无线资源控制(Radio Resource Control),RRC)和控制面的PDCP(即PDCP-C),在用户面,CU包含服务数据适配协议(Service Data Adaptation Protocol,SDAP)和用户面的PDCP(即PDCP-U)。
在NR中,针对低时延业务或者周期业务的需求,NR支持上行半静态的CG传输方式,以减少信令交互流程,保证低时延要求。CG传输的资源可通过RRC信令半静态地配置,当业务数据到来时,终端可在CG的上行信道上发送数据。NR支持type 1和type 2两种类型的配置授权物理上行共享信道(CG Physical Uplink Shared Channel,CG PUSCH),其中,对于type 1的CG PUSCH,RRC参数配置后,终端即可在CG PUSCH上传输数据,对于type 2的CG PUSCH,RRC参数配置且DCI激活CG PUSCH后,终端方可在CG PUSCH上传输数据。
为了减少上行同步(即随机接入过程)造成的LTM切换中断时间,3GPP讨论通过了基于早随机接入信道(Early Random Access Channel,Early-rach)或无随机接入信道(Random Access Channel less,RACH-less)的切换方案。其中,Early-rach,即候选小区为终端分配免竞争的随机接入(Contention Free Random Access,CFRA)资源,终端在切换发起之前向候 选小区执行RACH,以获取候选小区时间提前量(Time Advanced,TA)值;RACH-less,即终端在切换过程中不执行RACH,候选小区的TA值通过Early-rach过程获得,或者候选小区的TA值与源小区一样而无需获取;在RACH-less过程中,目标小区需要通过动态调度或CG调度的方式为终端分配上行资源,以使终端在对应资源上传输切换完成指示。
由上可知,对于无随机接入信道(Random Access Channel less,RACH-less)切换,层一层二触发的移动性(L1/L2 triggered mobility,LTM)中支持的方案包括:至少一个候选小区中的目标小区提前为终端提供周期性的上行配置授权(configured grant,CG)资源,终端在接收到当前驻留小区发送的切换命令之后,使用该目标小区分配的CG资源进行上行传输,以完成RACH-less切换。然而,当多个共享相同CG资源的终端同时发起RACH-less切换时,由于该多个终端使用的CG资源的冲突,因此会导致部分终端的RACH-less切换时延过大,甚至切换失败。
为了解决上述问题,在本申请实施例提供的资源调度方法中,第一终端可以接收第一节点设备发送的小区切换命令,小区切换命令用于指示第一终端切换至第一小区,小区切换命令包括第一指示信息,第一指示信息用于指示第一终端对应的CG资源是否可用;并基于第一指示信息,接入第一小区。通过第一指示信息向该第一终端指示为该第一终端分配的CG资源是否可用的方式,可以使得该第一终端可以根据该第一指示信息的指示,确定是否使用该CG资源进行上行传输。从而当多个共享相同CG资源的终端同时发起RACH-less切换时,可以避免该多个终端使用的CG资源冲突导致的部分终端的RACH-less切换时延过大,甚至切换失败。

可选地,本申请实施例中,若上述第一节点设备对应的任意两个终端所关联的上述CG资源的标识或上述CG资源的索引均不同,则该第一节点设备可以判断该第一节点设备对应的终端未分配相同的CG资源。
本申请实施例中,由于上述CG资源的标识信息或上述CG资源的索引信息可以用于:上述第一节点设备判断该第一节点设备对应的终端是否分配了相同的CG资源,因此该第一节点设备可以通过该CG资源的标识信息或该CG资源的索引信息,快速判断该第一节点设备对应的终端是否被分配了相同的CG资源。
可选地,本申请实施例中,上述至少一个终端标识列表信息中的每个终端标识列表信息对应至少一个终端。示例性地,该至少一个终端标识列表信息中的第一终端标识列表信息可以用于指示:该第一终端标识列表信息对应的所有终端分配了相同的CG资源。

本申请实施例中,由于上述第一终端标识列表信息可以用于指示:该第一终端标识列表信息对应的所有终端分配了相同的CG资源,因此可以便于上述第一节点设备确定该第一节点设备对应的终端是否被分配了相同的CG资源。
步骤302、第一节点设备向第一终端发送第一指示信息。

例如,上述LTM切换命令可以为LTM Command MAC CE,上述L3切换命令可以为包含ReconfigurationWithSync的RRC重配消息。
可选地,本申请实施例中,当上述比特信息指示1时,表示上述第一终端对应的CG资源可用;当该比特信息指示0时,表示该第一终端对应的CG资源不可用。或者,当该比特信息指示0时,表示该第一终端对应的CG资源可用;当该比特信息指示1时,表示该第一终端对应的CG资源不可用。
本申请实施例中,由于上述第一指示信息可以为:用于指示上述第一终端切换至上述第一小区的小区切换命令中的比特信息,因此通过该比特信息的指示,可以便于该第一终端快速获知该第一终端对应的CG资源是否可用。
示例性地,假设上述第一节点设备为第一DU,上述第二节点设备为第二DU,那么该第二DU可以先将上述至少一个CG资源配置信息发送给该第二DU所属的第二CU,然后该第二CU再将该至少一个CG资源配置信息发送给该第一DU所属的第一CU,最后该第一CU再将该至少一个CG资源配置信息发送给该第一DU。
需要说明的是,若上述第一DU和上述第二DU所属同一CU,则上述第一CU和上述第二CU为相同节点。
可选地,本申请实施例中,在上述第一CU从上述第二CU接收上述至少一个CG资源配置信息之后,该第一CU可以为上述第一终端配置至少一个候选小区配置,该至少一个候选小区配置中包括上述第一小区对应的第一小区配置,该第一小区配置包括该至少一个CG资源配置信息。

在本申请实施例提供的资源调度方法中,通过第一指示信息向该第一终端指示为该第一终端分配的CG资源是否可用的方式,可以使得该第一终端可以根据该第一指示信息的指示,确定是否使用该CG资源进行上行传输。从而当多个共享相同CG资源的终端同时发起RACH-less切换时,可以避免该多个终端使用的CG资源冲突导致的部分终端的RACH-less切换时延过大,甚至切换失败。
本申请实施例提供另一种资源调度方法,图4示出了本申请实施例提供的资源调度方法 的流程图。如图4所示,本申请实施例提供的资源调度方法可以包括下述的步骤401和步骤402。
步骤401、第一终端接收第一节点设备发送的小区切换命令。
其中,上述小区切换命令用于指示上述第一终端切换至第一小区,该小区切换命令包括第一指示信息,该第一指示信息用于指示该第一终端对应的CG资源是否可用。

步骤402、第一终端基于第一指示信息,接入第一小区。
可选地,本申请实施例中,上述步骤402具体可以通过下述的步骤402a实现。
步骤402a、第一终端根据第一指示信息,以及是否获取到第一小区的TA值,接入第一小区。
可选地,本申请实施例中,上述第一小区的TA值可以由上述第一终端通过以下至少之一获取:
上述小区切换命令中携带的上述第一小区的TA值;
上述小区切换命令中携带的上述第一小区的TA相关信息,例如,该相关信息可以为:用于指示上述第一终端在该第一小区的TA值和在当前接入小区的某个TAG(即标签)相同的信息;
网络配置,例如,该第一终端可以通过UE based TA测量过程获取上述第一小区TA值。
可选地,本申请实施例中,若上述第一终端未获取到上述第一小区的TA值,则可以认为上述小区切换命令中未携带上述第一小区的TA值和上述第一小区的TA相关信息,且该第一终端无法通过UE based TA测量过程获取该第一小区TA值。
本申请实施例中,由于上述第一终端可以根据上述第一指示信息,以及是否获取到上述第一小区的TA值,接入上述第一小区,因此可以避免多个终端使用的CG资源冲突导致的部分终端的RACH-less切换时延过大,甚至切换失败。
可选地,本申请实施例中,上述步骤402a具体可以通过下述的步骤402a1、步骤402a2或步骤402a3实现。
步骤402a1、在第一指示信息指示CG资源可用,且已获取到第一小区的TA值的情况下,第一终端使用CG资源传输上行数据,并执行基于配置授权的RACH-less切换流程接入第一小区。
步骤402a2、在第一指示信息指示CG资源不可用,且未获取到第一小区的TA值的情况下,第一终端执行RACH切换流程接入第一小区。
步骤402a3、在第一指示信息指示CG资源不可用,且已获取到第一小区的TA值的情况下,第一终端监听第一小区的上行动态调度,并执行基于动态调度的RACH-less切换流程接入第一小区。
对于上述基于配置授权的RACH-less切换流程、上述RACH切换流程,以及上述基于动态调度的RACH-less切换流程的具体描述,可以参照相关技术中的相关描述,为了避免重复,此处不再赘述。
本申请实施例中,由于上述第一终端可以根据上述第一指示信息指示的CG资源是否可用,以及是否获取到上述第一小区的TA值,执行不同的切换流程接入上述第一小区,因此可以进一步避免多个终端使用的CG资源冲突导致的部分终端的RACH-less切换时延过大,甚至切换失败。
对本申请实施例提供的资源调度方法的其它描述,具体可以参照上述第一节点设备侧方 法实施例中的相关描述,为了避免重复,此处不再赘述。
在本申请实施例提供的资源调度方法中,通过第一指示信息向该第一终端指示为该第一终端分配的CG资源是否可用的方式,可以使得该第一终端可以根据该第一指示信息的指示,确定是否使用该CG资源进行上行传输。从而当多个共享相同CG资源的终端同时发起RACH-less切换时,可以避免该多个终端使用的CG资源冲突导致的部分终端的RACH-less切换时延过大,甚至切换失败。
本申请实施例提供又一种资源调度方法,图5示出了本申请实施例提供的资源调度方法的流程图。如图5所示,本申请实施例提供的资源调度方法可以包括下述的步骤501至步骤503。
步骤501、第二节点设备接收第一节点设备发送的第一通知消息。
其中,上述第一通知消息用于指示:上述第一节点设备对应的第二终端发起切换至上述第二节点设备对应的第一小区。
可选地,本申请实施例中,上述第一通知消息可以包括:上述第二终端的终端标识、上述第一小区的小区标识,以及与该第二终端对应的传输配置指示(Transmission Configuration Indicator,TCI)状态标识。
可选地,本申请实施例中,上述TCI状态标识可以是上述第一节点设备向上述第二终端发送的小区切换命令中携带的。
本申请实施例中,由于上述第一通知消息可以包括上述第二终端的终端标识、上述第一小区的小区标识,以及上述TCI状态标识,因此可以便于第二节点设备获知需切换至该第一小区的第二终端的相关信息。
示例性地,假设上述第一节点设备为第一DU,上述第二节点设备为第二DU,那么该第一DU可以先将上述第一通知消息发送给该第一DU所属的第一CU,然后该第一CU再将该第一通知消息发送给该第二DU所属的第二CU,最后该第二CU再将该第一通知消息发送给该第二DU。
需要说明的是,若上述第一DU和上述第二DU所属同一CU,则上述第一CU和上述第二CU为相同节点。
可选地,本申请实施例中,上述第一节点设备在向上述第二节点设备发送上述第一通知消息之前,可以先根据对上述第一小区的测量结果,向分配了相同的第一小区的CG资源的终端,同时或短时间内先后发送小区切换命令。当一个终端接收到了对应的小区切换命令之后,若该终端获取到了该第一小区的TA值,则该终端执行基于配置授权的RACH-less切换流程,同时监听该第一小区的物理下行控制信道(Physical Downlink Control Channel,PDCCH),若监听到上行调度,则该终端执行基于动态调度的RACH-less切换流程;若该终端未获取到该第一小区的TA值,则该终端执行基于RACH的切换流程。
步骤502、第二节点设备基于第一通知消息,确定第二终端对应的CG资源是否与其他终端对应的CG资源存在冲突。
可选地,本申请实施例中,上述第二终端对应的CG资源可以为:上述第二节点设备为该第二终端分配的CG资源。
可选地,本申请实施例中,上述步骤502具体可以通过下述的步骤502a实现。
步骤502a、第二节点设备根据第二终端对应的CG资源,以及第二终端对应的TCI状态标识,确定第二终端对应的CG资源是否与其他终端对应的CG资源存在冲突。
可选地,本申请实施例中,上述第二终端和上述其他终端可以均为上述第一节点设备对应的终端。
可选地,本申请实施例中,若上述第二终端对应的CG资源与至少一个其他终端对应的 CG资源相同,且该第二终端对应的TCI状态标识与至少一个其他终端对应的TCI状态标识相同,则第二节点设备可以确定第二终端对应的CG资源与其他终端对应的CG资源存在冲突;若上述第二终端对应的CG资源与任一其他终端对应的CG资源均不同,且该第二终端对应的TCI状态标识与任一其他终端对应的TCI状态标识均不同,则第二节点设备可以确定第二终端对应的CG资源与其他终端对应的CG资源不存在冲突。
本申请实施例中,由于第二节点设备可以根据为上述第二终端分配的CG资源,以及该第二终端对应的TCI状态标识,确定第二终端对应的CG资源是否与其他终端对应的CG资源存在冲突,而TCI状态标识可以明确指示TCI状态,从而可以使第二节点设备能够准确确定第二终端对应的CG资源是否与其他终端对应的CG资源存在冲突。
