背景技术
随着无线通信技术的发展,高频通信可提供更宽的系统带宽,同低频带相比,能够在同样大小的天线面板上布置更多的天线阵元,利于大规模天线在基站和终端(User Equipment,UE)中部署。另外,利用波束赋形技术可以形成指向性更强以及波瓣更窄的波束,提升系统覆盖范围和容量。因此,将波束赋形技术与高频通信、大规模天线技术相结合,已成为无线通信系统的发展趋势。
而多载波系统因能满足更大带宽需求被引入到无线通信系统。其中,典型的多载波系统(例如在载波聚合场景)中的服务小区包括:一个主服务小区(Primary Cell,PCell)和至少一个辅服务小区(Secondary Cell,SCell),且PCell和每一SCell都可以为终端提供服务,以实现终端可以同时有多个服务小区。
由于毫米波系统存在信道突然波动、意外障碍中断以及终端旋转等因素影响,会可能使得终端与网络侧设备之间的波束失败,从而使得终端的通信性能比较低。

参见图1,图1是本公开实施例可应用的网络结构示意图,如图1所示,包括终端(User Equipment,UE)11和网络侧设备12,其中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定终端11的具体类型。上述网络侧设备12可以为宏站、LTE eNB、5G NR NB等;网络侧设备12也可以是小站,如低功率节点(Low Power Node,LPN)pico、femto等小站,或者网络侧设备12可以为接入点(access point,AP);基站也可以是中央单元(Central Unit,CU)与其管理和控制的多个传输接收点(Transmission Reception Point,TRP)共同组成的网络节点。需要说明的是,在本公开实施例中并不限定网络侧设备12的具体类型。
应当说明的是,本公开实施例的波束失败处理方法应用于多载波系统,在典型的多载波系统中(例如载波聚合场景),终端11可以连接多个小区,即多个小区同时服务于该终端,且多个小区通常包括:一个主小区(Primary Cell,PCell)和至少一个辅小区(Secondary Cell,SCell)。
以下对本公开实施例的承载的波束失败处理方法进行说明。
参见图2,图2是本公开实施例提供的一种波束失败处理方法的流程图,应用于终端,如图2所示,包括以下步骤:
步骤201、根据波束失败检测参考信号BFD RS(Beam Failure Detection Reference Signal,BFD RS)资源组,确定第一小区组是否发生波束失败,其中,BFD RS资源组配置于第一小区组内。
本公开实施例中,上述第一小区组可以是协议约定或者网络侧设备配置,包括上述终端连接的小区中的至少一个小区的小区组,且上述BFD RS资源组配置于第一小区组内,可以是上述BFD RS资源组配置于上述包括至少一个小区的第一小区组中的部分或者全部小区。
其中,上述第一小区组可以仅包括有一个小区,如第一小区组包括主小区或者一个辅小区;或者,也可以包括满足预设条件的多个小区,如处于同 一频带的多个小区位于第一小区组。
可选的,第一小区组包括:
处于同一频带内的部分或者全部辅小区;或者,
处于同一频带内的主小区以及至少一个辅小区。
这里,由于处于同一频带内小区上波束的空间特性相近或者相同,如空间信息、空间参数、准共址(Quasi co-location,QCL)信息等中的至少一项相近或者相同,通过将处于同一频带内的小区预先约定或者配置于同一小区组内,使得同一小区组内各小区之间的关联性较高。
另外,上述终端连接的多个小区中,可以是协议约定或者预配置一个或者多个小区组,而在协议约定或者预配置一个小区组的情况下,该一个小区组为上述第一小区组,且第一小区组之外的其他小区未进行分组;或者,也可以是配置有多个小区组,终端连接的每一小区通过协议约定或者预配置于一个对应的小区组内,且上述第一小区组可以是该多个小区组中的任一小区组。
例如:在上述终端连接的多个小区包括PCell、SCell 1、SCell 2、SCell 3和SCell 4,且PCell和SCell 1处于同一频带,以及SCell 2、SCell 3和SCell4处于同一频带的情况下,可以将PCell和SCell 1预配置于小区组1,SCell2、SCell 3和SCell 4预配置于小区组2。
需要说明的是,在上述终端连接的小区中的一个或者多个小区组中,每一小区组中配置有一组对应的BFD RS资源。而上述第一小区组可以是上述一个或者多个小区组中的任一小区组,在此为便于区分,本公开实施例所称的BFD RS资源组配置于第一小区组,而第一小区组之外的小区组配置的BFD RS资源组称为其他BFD RS资源组。
其中,上述BFD RS资源组配置于第一小区组内,可以包括但不局限于以下任一项:
在第一小区组仅包括一个小区(如主小区或者一个辅小区)的情况下,BFD RS资源组配置于该一个小区上;或者,
在第一小区组包括多个小区的情况下,BFD RS资源组作为该多个小区的公共RS资源,且BFD RS资源组配置于该多个小区中的部分或者全部小区 上,从而可以降低资源开销。
可选的,上述BFD RS资源组配置于第一小区组中的N个预设小区内,N为正整数,其中:
N个预设小区为第一小区组中的部分小区,且每一预设小区为具有预设小区索引(Cell Index)的小区;或者,
N个预设小区为第一小区组中的全部小区;或者,
在第一小区组包括主小区的情况下,N个预设小区为主小区。
这里,BFD RS资源组可以配置于第一小区组中的部分或者全部小区;或者,在第一小区组包括主小区的情况下,BFD RS资源组配置于主小区,从而使在各小区组中配置BFD RS资源组的方式灵活。
本公开实施例中,上述BFD RS资源组配置于第一小区组中,可以是由网络侧设备配置实现,可选的,上述步骤101之前,还包括:接收网络侧设备发送的第一配置信息,第一配置信息用于将BFD RS资源组配置于所述第一小区组内,从而根据实际需求准确为各小区组配置BFD RS资源组。
其中,上述第一配置信息可以是任何能够实现将上述BFD RS资源组配置于第一小区组内的信息,例如:上述第一配置信息可以包括上述BFD RS资源组与第一小区组的关联关系信息等。当然,上述第一配置信息还可以包括用于将其他BFD RS资源组配置于对应的小区组的信息,在此并不进行限定。
另外,为实现将BFD RS资源组配置于第一小区组内的部分小区上,即BFD RS资源组配置于具有预设小区索引的N个预设小区上,可选的,第一配置信息包括BFD RS资源组所在小区的预设小区索引,使将BFD RS资源组配置于第一小区组内的部分小区上的方式简单,且降低资源开销。
例如:在上述第一小区组包括SCell 2、SCell 3和SCell 4,且SCell 3和SCell 4的小区索引为预设小区索引的情况下,若需要将BFD RS资源组配置于SCell 3和SCell 4,则上述第一配置信息包括SCell 3和SCell 4的小区索引。
需要说明的是,上述接收网络侧设备发送的第一配置信息,可以是接收网络侧设备通过无线资源控制(Radio Resource Control,RRC)发送的第一配置信息,或者,上述第一配置信息也可以是网络侧设备通过其他资源或者信 令发送,在此并不进行限定。
本公开实施例中,上述步骤201中,根据BFD RS资源组确定第一小区组是否发生波束失败,可以是:终端检测配置BFD RS资源组的部分或者全部小区是否发生波束失败,如根据各小区的波束的BFD RS资源测量信号传输质量,若信号传输质量低于预设门限,则认为该小区发生波束失败,等等;并根据部分或者全部小区是否发生波束失败,确定第一小区组是否发生波束失败。
需要说明的是,上述BFD RS资源组包括至少一个BFD RS资源,而上述BFD RS资源组配置于第一小区组内,可以理解为该至少一个BFD RS资源配置于第一小区组内的部分或者全部小区上。
例如:在第一小区组包括PCell和SCell 1的小区组1的情况下,若BFD RS资源组包括BFD RS资源1、BFD RS资源2和BFD RS资源3,则可以将BFD RS资源1、BFD RS资源2和BFD RS资源3配置于PCell和SCell中的至少一个小区,如BFD RS资源1配置于PCell且BFD RS资源2和BFD RS资源3配置于SCell 1,或者,BFD RS资源1、BFD RS资源2和BFD RS资源3配置于SCell 1,等等。
当然,上述终端检测配置BFD RS资源组的部分或者全部小区是否发生波束失败,可以理解为终端对第一小区组中每一配置有BFD RS资源的小区的BFD RS资源进行测量,以确定各配置有BFD RS资源的小区是否发生波束失败。
另外,由于上述BFD RS资源组中,可以是多个BFD RS资源同时配置于一个小区上,且不同BFD RS资源用于在该一个小区上测量不同波束,则上述检测小区是否发生波束失败,可以是检测到该小区上对应有BFD RS资源的波束中的部分或者全部发生失败的情况下,确定该小区发生波束失败。
本公开具体实施例中,由于上述BFD RS资源组可以是配置于第一小区组中的N个预设小区,而在N=1,即上述BFD RS资源组配置于一个预设小区(如PCell)的情况下,若该一个预设小区发生波束失败,则确定上述第一小区组发生波束失败。
或者,上述BFD RS资源组可以配置于多个预设小区,即可选的,在N 个预设小区为上述部分小区或上述全部小区,且N大于1的情况下,上述确定第一小区组是否发生波束失败,包括:
在所述N个预设小区中全部小区发生波束失败的情况下,确定所述第一小区组发生波束失败;
在所述N个预设小区中第一数量的小区发生波束失败的情况下,确定所述第一小区组发生波束失败。
这里,可以是在N个预设小区中全部小区或者第一数量的小区发生波束失败的情况下,确定第一小区组发生波束失败,使确定第一小区组是否发生波束失败的方式更灵活。
其中,由于处于同一小区组内的多个小区通常具有关联性,例如:在上述第一小区组包括处于同一频带的多个小区的情况下,第一小区组内的多个小区上的波束的空间特性相同或相近等,则当同一小区的多个小区中任一小区发生波束失败时,该小区组中其他小区发生波束失败的可能性较大,故在N个预设小区中第一数量的小区发生波束失败的情况下,可以认定第一小区组发生波束失败。
另外,上述第一数量可以是由协议约定、网络侧设备配置或者终端预先设定的数量,且第一数量可以是一个或者其他小于N的数量,在此并不进行限定。
步骤202、在第一小区组发生波束失败的情况下,向网络侧设备发送波束失败恢复请求消息。
其中,在上述步骤201确定第一小区组发生波束失败的情况下,终端可以向网络侧设备发送波束失败恢复请求消息,以通知网络侧设备终端在第一小区组发生波束失败。
另外,在第一小区组发生波束失败的情况下,可以在终端与网络侧设备之间寻找替代波束,并通过替代波束替代第一小区组中的故障波束进行数据传输和接收,从而实现故障恢复。当然,该替代波束也可以是协议约定或者网络侧设备配置等,在此并不进行限定。
或者,终端也可以通过以下实施方式一确定替代波束的信息,从而网络侧设备通过替代波束的信息确定替代波束,具体如下:
实施方式一
本实施方式中,在上述向网络侧设备发送波束失败恢复请求消息之前,还包括:确定替代波束的信息。
其中,上述确定替代波束的信息的方式,可以包括但不局限于如下方式一和方式二:
方式一
方式一中,网络侧设备为终端配置用于进行波束训练的RS资源集合,且终端对该RS资源集合中各RS资源进行测量,确定该RS资源集合中满足预设条件的RS资源,如若某个RS资源的L1-RSRP高于门限值,则确定该RS资源满足预设条件。
另外,终端将上述确定的满足预设条件的至少一个RS资源的信息上报给网络侧设备,上报方式可以包括:由波束失败恢复请求消息携带发送至网络侧设备,或者由波束报告携带发送至网络侧设备。以使网络侧设备根据终端上报的至少一个RS资源的信息,确定替代波束,上述确定出的替代波束也即候选波束。
应当说明的是,上述各RS资源的信息可以包括RS资源索引、层一参考信号接收功率(Layer 1Reference Signal Received Power,L1-RSRP)和层一信号与干扰加噪声比(Layer 1Signal-to-Noise And Interference Ratio,L1-SINR)等中的至少一项。
方式二
方式二中,上述向网络侧设备发送波束失败恢复请求消息之前,还包括:根据候选波束RS资源组确定目标候选波束RS资源;

这里,终端可以根据候选波束RS资源组确定目标候选波束RS资源,且波束失败恢复请求消息用于指示目标候选波束RS资源的信息,以使终端根据目标候选波束RS资源的信息,可以直接确定候选波束,从而提升确定替代波束的效率。
方式二中,上述候选波束RS资源组可以是由网络侧设备配置于终端,可 选的,上述步骤203之前,包括:
接收网络侧设备发送的第二配置信息,第二配置信息用于将候选波束RS资源组配置于第二小区组内。
这里,网络侧设备可以通过第二配置信息将候选波束RS资源组配置于第二小区组内,从而根据实际需求准确为各小区组配置候选波束RS资源组。
需要说明的是,第二小区组与第一小区组可以是同一小区组;或者,第二小区组与第一小区组也可以是不同小区组,例如:第一小区组包括PCell和SCell 1,且第二小区组包括SCell 2、SCell 3和SCell 4等;或者,第二小区组和第一小区组中有部分小区相同。
方式二中,上述候选波束RS资源组配置于第二小区组,可以是候选波束RS资源组配置于第二小区组中的部分或者全部小区。

在第二小区组包括主小区的情况下,所述M个预设小区为所述主小区。
其中,上述候选波束RS资源组配置于第二小区组的实现原理,可以与上述BFD RS资源组配置于第一小区组的实现原理相似,在此并不进行赘述。
应当说明的是,上述第二小区组包括至少一个小区,上述候选波束RS资源组包括至少一个候选波束RS资源,上述候选波束RS资源组配置于第二小区组,可以是上述至少一个候选波束RS资源配置于上述至少一个小区中的部分或者全部小区。
