背景技术
未来第五代(Generation,5G)移动通信系统,或称为新空口(New Radio,NR)系统中,为达到下行链路传输速率20Gbps,上行链路传输速率10Gbps的目标,高频通信和大规模天线技术将会被引入。具体地,高频通信可提供更宽的系统带宽,天线尺寸也可以更小,更加有利于大规模天线在基站和终端中部署。但是,高频通信存在路径损耗较大、容易受干扰、链路较脆弱等缺点,而大规模天线技术可提供较大天线增益,因此,高频通信与大规模天线的结合是未来5G移动通信系统的必然趋势。
然而,高频通信中链路脆弱性的问题依然存在。相关技术中,当高频通信中信号遇到遮挡时,可采用波束失败恢复机制来切换波束,将通信链路从较差的波束切换至通信链路较好的候选波束,以避免无线链路失败。相关技术虽然给出了5G系统中支持多种信道或信号发送波束失败恢复请求,但并没有给出如何配置波束失败恢复请求对应的多种信道或信号的配置方法,以及终端上行发送行为的处理机制。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等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。
本公开实施例提供了一种波束失败处理方法,应用于终端侧,如图1所示,具体包括以下步骤:
步骤11:获取网络设备发送的物理随机接入信道PRACH资源配置信息 (例如,NR-PRACH资源配置信息)和物理上行控制信道PUCCH资源配置信息(例如,NR-PUCCH资源配置信息),所属领域技术人员可以理解,下面实施例中以NR系统中的PRACH以及PUCCH为例进行说明,并不构成对本发明的限制。
其中,NR-PRACH资源配置信息用于指示网络设备为波束失败恢复请求配置的NR-PRACH传输资源,NR-PUCCH资源配置信息用于指示网络设备为波束失败恢复请求配置的NR-PUCCH传输资源。也就是说,网络设备配置的NR-PRACH资源中,一部分资源用于终端的随机接入,另一部分资源用于在波束失败时供终端发送波束失败恢复请求,且这两部分资源正交,即,用于发送波束失败恢复请求的NR-PRACH资源与用于随机接入的普通NR-PRACH资源正交。值得指出的是,这里所说的NR-PRACH资源可以是非竞争NR-PRACH资源,亦可以是竞争NR-PRACH资源。
具体地,NR-PRACH资源配置信息包括:波束资源指示信息、最大重传次数信息、NR-PRACH配置索引信息、时域起始子帧或时隙或符号信息、频域偏移量信息和跳频配置信息中的至少一项。
NR-PUCCH资源配置信息包括:波束资源指示信息、最大重传次数信息、NR-PUCCH类型信息、NR-PUCCH格式信息和周期信息中的至少一项。也就是说,网络设备配置波束失败恢复请求可通过NR-PUCCH进行发送。
其中,步骤11具体包括:通过无线资源控制RRC信令,接收网络设备发送的NR-PRACH资源配置信息和NR-PUCCH资源配置信息。即,上述NR-PRACH资源配置信息和NR-PUCCH资源配置信息可通过无线资源(RRC,Radio Resource Control)信令指示。
步骤12:接收网络设备发送的第一指示信息。
其中,第一指示信息用于指示波束失败恢复请求的发送信道或信号。由于网络设备配置波束失败恢复请求既可通过NR-PRACH资源发送,又可通过NR-PUCCH资源发送,因此网络设备可根据当前网络资源占用情况向终端发送用于指示采用何种资源发送波束失败恢复请求的第一指示信息。即,第一指示信息为波束失败恢复请求发送信道或信号的指示,用于指示波束失败恢复请求是基于NR-PRACH资源发送还是基于NR-PUCCH资源发送。
步骤13:若检测到波束失败,则根据第一指示信息、NR-PRACH资源配置信息和/或NR-PUCCH资源配置信息,确定发送波束失败恢复请求的目标传输资源。
由于不同的网络资源占用情况,网络设备可为波束失败恢复请求配置不同的传输资源。具体地,步骤13包括:若第一指示信息指示仅支持通过NR-PRACH发送波束失败恢复请求,则根据NR-PRACH资源配置信息,确定发送波束失败恢复请求的第一NR-PRACH资源。当网络设备发送的用于指示波束失败恢复请求发送信道或信号的第一指示信息仅指示了支持基于NR-PRACH资源的发送,那么当终端检测到波束失败时,确定采用第一NR-PRACH资源发送波束失败恢复请求。
具体地,步骤13还包括:若第一指示信息指示仅支持通过NR-PUCCH发送波束失败恢复请求,则根据NR-PUCCH资源配置信息,确定发送波束失败恢复请求的第一NR-PUCCH资源。当网络设备发送的用于指示波束失败恢复请求发送信道或信号的第一指示信息仅指示了支持基于NR-PUCCH资源的发送,那么当终端检测到波束失败时,确定采用第一NR-PUCCH资源发送波束失败恢复请求。
具体地,步骤13还包括:若第一指示信息指示支持通过NR-PRACH和NR-PUCCH发送波束失败恢复请求,则根据候选波束数门限值、NR-PRACH资源配置信息和NR-PUCCH资源配置信息,确定发送波束失败恢复请求的第二NR-PRACH资源或第二NR-PUCCH资源。
进一步地,上述根据候选波束数门限值、NR-PRACH资源配置信息和NR-PUCCH资源配置信息,确定发送波束失败恢复请求的第二NR-PRACH资源或第二NR-PUCCH资源的步骤,包括:接收网络设备发送的用于指示候选波束数门限值的第三指示信息;若候选波束数小于第三指示信息指示的候选波束数门限值,则根据NR-PRACH资源配置信息,确定发送波束失败恢复请求的第二NR-PRACH资源;若候选波束数大于所述第三指示信息指示的候选波束数门限值,则根据NR-PUCCH资源配置信息,确定发送波束失败恢复请求的第二NR-PUCCH资源。这里,候选波束数门限值是终端用于选择NR-PRACH资源发送还是选择NR-PUCCH资源发送的门限条件,当候选波 束数小于预设门限值时,确定采用NR-PRACH资源发送;当候选波束数大于预设门限值时,确定采用NR-PUCCH资源发送。
具体地,步骤13还包括:若第一指示信息指示支持通过NR-PRACH和NR-PUCCH发送波束失败恢复请求,则根据NR-PRACH资源配置信息和NR-PUCCH资源配置信息,确定发送波束失败恢复请求的第三NR-PRACH资源和第三NR-PUCCH资源。
步骤14:通过目标传输资源,向网络设备发送波束失败恢复请求。
进一步地,步骤14具体包括:接收网络设备发送的第二指示信息;其中,第二指示信息用于指示波束失败恢复请求的发送内容;通过目标传输资源,向网络设备发送携带有发送内容的波束失败恢复请求。
其中,终端通过RRC信令、媒体介入控制MAC层控制单元CE或物理层下行控制指示DCI信息,接收网络设备发送的第一指示信息和第二指示信息。即上述第一指示信息和第二指示信息可通过RRC信令或媒体接入控制(Media Access Control,MAC)层控制单元(Control Element,CE)或物理层下行控制指示(Downlink Control Indicator,DCI)承载。
其中,第二指示信息指示的发送内容至少包括:终端标识信息和/或候选波束资源标识信息。候选波束资源标识信息中包括一个或多个波束的资源标识。NR-PRACH和/或NR-PUCCH上携带波束失败恢复请求的发送内容至少包含终端标识信息和候选波束资源标识信息。
若目标传输资源为NR-PRACH资源,通过目标传输资源向网络设备发送携带有发送内容的波束失败恢复请求的步骤包括:通过NR-PRACH资源,向网络设备发送对应的波束失败恢复请求。其中,NR-PRACH资源隐式指示终端标识信息和候选波束资源标识信息。
若目标传输资源为NR-PUCCH资源,通过目标传输资源向网络设备发送携带有发送内容的波束失败恢复请求的步骤包括:通过NR-PUCCH资源,向网络设备发送携带有终端标识信息和候选波束资源标识信息的波束失败恢复请求。
或者,通过NR-PUCCH资源携带的信息,向网络设备发送携带有终端标识信息的波束失败恢复请求。其中,NR-PUCCH资源携带的信息对应的时域 传输资源分组信息或频域传输资源分组信息隐式指示候选波束资源标识信息。其中,NR-PUCCH资源中可预定义一种新的信息格式来传输波束失败恢复请求,或者,通过NR-PUCCH资源中传输的调度请求(Scheduling Request,SR)信息和/或应答信息(ACK/NACK)和/或信道状态信息(Channel State Information,CSI)来传输波束失败恢复请求。具体地,以SR信息为例,NR-PUCCH资源的SR信息的不同分组可以表示不同的候选波束资源标识信息,或者,NR-PUCCH资源的SR信息的不同分组可以表示是否存在候选波束资源标识信息,例如:分组1表示存在候选波束资源标识信息(对2个BPL的情况默认直接切换),分组2表示不存在候选波束资源标识信息并重新做波束扫描,以快速恢复波束链路。进一步地,NR-PUCCH资源的SR信息可以按照时分分组方式隐式携带候选波束资源标识信息。如:奇数子帧、时隙或符号携带部分候选波束资源标识信息,偶数子帧、时隙或符号携带其余候选波束资源标识信息。或者,NR-PUCCH资源的SR信息可以按照频分分组方式隐式携带候选波束信息。如:奇数物理资源块、子带、部分带宽或载波携带部分候选波束资源标识信息,偶数物理资源块、子带、部分带宽或载波携带其余候选波束资源标识信息。
若目标传输资源为NR-PRACH资源和NR-PUCCH资源,同时通过NR-PRACH和NR-PUCCH进行波束失败恢复请求发送时,NR-PRACH和NR-PUCCH中携带的波束失败恢复请求的发送内容相同。通过目标传输资源向网络设备发送携带有发送内容的波束失败恢复请求的步骤包括:通过NR-PRACH资源,向网络设备发送对应的波束失败恢复请求。其中,NR-PRACH资源隐式指示终端标识信息和候选波束资源标识信息。并通过NR-PUCCH资源,向网络设备发送携带有终端标识信息和候选波束资源标识信息的波束失败恢复请求。其中,NR-PRACH资源隐式指示终端标识信息和候选波束资源标识信息,与NR-PUCCH资源显示发送的终端标识信息和候选波束资源标识信息相同。假设网络设备配置波束失败恢复请求的发送信道或信号包含NR-PRACH和NR-PUCCH,且NR-PRACH和NR-PUCCH携带的波束失败恢复请求信息相同。UE标识为1的UE发生波束失败,且发现候选波束资源标识为0和1。终端可利用NR-PRACH隐式发送终端标识1和候选 波束资源标识0和1至网络设备侧。网络设备侧可通过预配置的NR-PRACH资源识别终端标识,以及预分配的NR-PRACH资源分组确定候选波束资源标识。终端可利用NR-PUCCH显式发送终端标识1和候选波束资源标识0和1至网络设备侧。网络设备侧可通过预定义或复用现有的NR-PUCCH格式检测终端标识,候选波束资源标识。
进一步地,当目标传输资源为NR-PRACH资源和NR-PUCCH资源时,NR-PRACH资源和NR-PUCCH资源发送的发送内容亦可以不同,具体地,通过目标传输资源向网络设备发送携带有发送内容的波束失败恢复请求的步骤包括:通过NR-PRACH资源,向网络设备发送对应的波束失败恢复请求;其中,NR-PRACH资源隐式指示终端标识信息;并通过NR-PUCCH资源,向网络设备发送携带有候选波束资源标识信息的波束失败恢复请求。即,NR-PRACH中携带终端标识信息,NR-PUCCH中携带候选波束资源标识信息。
假设网络设备侧配置波束失败恢复请求的发送信道或信号包含NR-PRACH和NR-PUCCH,且NR-PRACH和NR-PUCCH携带的波束失败恢复请求的发内容不同。UE标识为1的UE发生波束失败,且发现候选波束资源标识为0和1。由于NR-PRACH资源有限,终端可利用NR-PRACH隐式发送终端标识1至网络设备侧。网络设备侧可通过预配置的NR-PRACH资源识别终端标识。终端还可利用NR-PUCCH显式发送候选波束资源标识0和1至网络设备侧,NR-PUCCH发送波束资源标识与NR-PRACH发送波束资源标识一一对应。网络设备侧可通过预定义或复用相关技术中的NR-PUCCH格式检测候选波束资源标识。
或者,通过NR-PRACH资源,向网络设备发送对应的波束失败恢复请求;其中,NR-PRACH资源隐式指示终端标识信息和候选波束中第一部分波束的第一波束资源标识信息;通过NR-PUCCH资源,向网络设备发送携带有终端标识信息和候选波束中第二部分波束的第二波束资源标识信息的波束失败恢复请求;其中,第二部分波束为候选波束中除第一部分波束之外的所有其他波束。即,NR-PRACH中携带终端标识信息和部分候选波束资源标识信息,NR-PUCCH中携带终端标识信息和其余候选波束资源标识信息。
进一步地,为保证波束失败恢复请求的可靠传输,通过目标传输资源向 网络设备发送携带有发送内容的波束失败恢复请求的步骤包括:通过目标传输资源,分多次向网络设备发送携带有发送内容的全部或部分信息的波束失败恢复请求。即,采用不同目标传输资源进行的每次波束失败恢复请求发送时,每次发送的波束失败恢复请求的发送内容可以相同也可以不同。
假设网络设备配置波束失败恢复请求的发送信道或信号为NR-PRACH,且NR-PRACH重传(除第一次传输外的其他次传输)携带波束失败恢复请求的发内容不同。终端标识为1的终端发生波束失败,且发现候选波束资源标识为0和1。这时,终端可利用NR-PRACH隐式发送终端标识1和候选波束资源标识0和1至网络设备侧。网络侧可通过预配置的NR-PRACH资源识别终端标识,以及根据预分配的NR-PRACH资源分组确定候选波束资源标识。进一步地,由于NR-PRACH携带资源能力有限,初次传输时,终端可通过NR-PRACH将终端标识1和候选波束资源标识0发送至网络设备侧;第一次重传时可通过NR-PRACH将终端标识1和候选波束资源标识1发送至网络设备侧。
本公开实施例的波束失败处理方法中,终端接收网络设备为发送波束失败恢复请求配置的NR-PRACH资源配置信息、NR-PUCCH资源配置信息,以及指示终端是通过NR-PRACH发送还是通过NR-PUCCH发送波束失败恢复请求的第一指示信息,终端在检测到波束失败时,根据第一指示信息、NR-PRACH资源配置信息和/或NR-PUCCH资源配置信息,确定发送波束失败恢复请求的目标传输资源,并通过该目标传输资源向网络设备发送相应的波束失败恢复请求,有效提高了波束失败恢复的效率,增强了高频通信链路传输可靠性。

以上实施例从终端侧介绍了本公开的波束失败处理方法,下面本实施例将结合附图对网络设备侧的波束失败处理方法做进一步介绍。
如图5所示,本公开实施例提供了一种波束失败处理方法,应用于网络设备侧,具体包括以下步骤:
步骤51:向终端发送物理随机接入信道NR-PRACH资源配置信息和物理上行控制信道NR-PUCCH资源配置信息。
其中,NR-PRACH资源配置信息用于指示网络设备为波束失败恢复请求配置的NR-PRACH传输资源,NR-PUCCH资源配置信息用于指示网络设备为波束失败恢复请求配置的NR-PUCCH传输资源。也就是说,网络设备配置的NR-PRACH资源中,一部分资源用于终端的随机接入,另一部分资源用于在波束失败时供终端发送波束失败恢复请求,且这两部分资源正交。
具体地,NR-PRACH资源配置信息包括:波束资源指示信息、最大重传次数信息、NR-PRACH配置索引信息、时域起始子帧或时隙或符号信息、频域偏移量信息和跳频配置信息中的至少一项。NR-PUCCH资源配置信息包括:波束资源指示信息、最大重传次数信息、NR-PUCCH类型信息、NR-PUCCH格式信息和周期信息中的至少一项。也就是说,网络设备配置波束失败恢复请求可通过NR-PUCCH进行发送。
具体地,步骤51包括:通过无线资源控制RRC信令,向终端发送 NR-PRACH资源配置信息和NR-PUCCH资源配置信息。即,上述NR-PRACH资源配置信息和NR-PUCCH资源配置信息可通过无线资源(Radio Resource Control,RRC)信令指示。
步骤52:向终端发送第一指示信息。
其中,第一指示信息用于指示波束失败恢复请求的发送信道或信号。由于网络设备配置波束失败恢复请求既可通过NR-PRACH资源发送,又可通过NR-PUCCH资源发送,因此网络设备可根据当前网络资源占用情况向终端发送用于指示采用何种资源发送波束失败恢复请求的第一指示信息。
具体地,步骤52包括:根据当前资源占用情况,向终端发送用于指示仅支持通过NR-PRACH发送波束失败恢复请求的第一指示信息。
具体地,步骤52包括:根据当前资源占用情况,向终端发送用于指示仅支持通过NR-PUCCH发送波束失败恢复请求的第一指示信息。
具体地,步骤52包括:根据当前资源占用情况,向终端发送用于指示支持通过NR-PRACH和NR-PUCCH发送波束失败恢复请求的第一指示信息。
进一步地,在根据当前资源占用情况,向终端发送用于指示支持通过NR-PRACH和NR-PUCCH发送波束失败恢复请求的第一指示信息的步骤之前,还包括:向终端发送用于指示候选波束数门限值的第三指示信息。
步骤53:接收终端在检测到波束失败后通过目标传输资源发送的波束失败恢复请求。
其中,目标传输资源为终端根据第一指示信息、NR-PRACH资源配置信息和NR-PUCCH资源配置信息确定的。
具体地,步骤53包括:向终端发送第二指示信息;其中,第二指示信息用于指示波束失败恢复请求的发送内容;接收终端在检测到波束失败后通过目标传输资源发送的、携带有发送内容的波束失败恢复请求。
其中,网络设备通过RRC信令、媒体介入控制MAC层控制单元CE或物理层下行控制指示DCI信息向终端发送第一指示信息和第二指示信息。即上述第一指示信息和第二指示信息可通过RRC信令或媒体接入控制(Media Access Control,MAC)层控制单元(Control Element,CE)或物理层下行控制指示(Downlink Control Indicator,DCI)承载。
其中,第二指示信息指示的发送内容至少包括:终端标识信息和/或候选波束资源标识信息。候选波束资源标识信息中包括一个或多个波束的资源标识。NR-PRACH和/或NR-PUCCH上携带波束失败恢复请求的发送内容至少包含终端标识信息和候选波束资源标识信息。
若目标传输资源为NR-PRACH资源,步骤53具体为:接收终端在检测到波束失败后通过NR-PRACH资源发送的波束失败恢复请求;根据NR-PRACH资源,隐式得到波束失败恢复请求对应的终端标识信息和候选波束资源标识信息。
若目标传输资源为NR-PUCCH资源,步骤53具体为:接收终端在检测到波束失败后通过NR-PUCCH资源发送的、携带有终端标识信息和候选波束资源标识信息的波束失败恢复请求。
若目标传输资源为NR-PUCCH资源,步骤53具体为:接收终端在检测到波束失败后通过NR-PUCCH资源携带的信息;根据NR-PUCCH资源携带的信息对应的时域传输资源分组信息或频域传输资源分组信息,隐式得到波束失败恢复请求对应的候选波束资源标识信息。其中,NR-PUCCH资源中可预定义一种新的信息格式来传输波束失败恢复请求,或者,通过NR-PUCCH资源中传输的调度请求SR信息和/或应答信息ACK/NACK和/或信道状态信息CSI来传输波束失败恢复请求。
若目标传输资源为NR-PRACH资源和NR-PUCCH资源,步骤53具体为:接收终端在检测到波束失败后通过NR-PRACH资源发送的波束失败恢复请求,根据NR-PRACH资源确定波束失败恢复请求对应的终端标识信息;以及接收通过NR-PUCCH资源发送的携带有候选波束资源标识信息的波束失败恢复请求;
或者,接收终端在检测到波束失败后通过NR-PRACH资源发送的波束失败恢复请求,根据NR-PRACH资源确定波束失败恢复请求对应的终端标识信息和候选波束中第一部分波束的第一波束资源标识信息;以及接收通过NR-PUCCH资源发送的、携带有终端标识信息和候选波束中第二部分波束的第二波束资源标识信息的波束失败恢复请求;其中,第二部分波束为候选波束中除第一部分波束之外的所有其他波束。
进一步地,接收终端在检测到波束失败后通过目标传输资源发送的、携带有发送内容的波束失败恢复请求的步骤包括:接收终端在检测到波束失败后分多次通过目标传输资源发送的、携带有所述发送内容的全部或部分信息的波束失败恢复请求。假设网络设备配置波束失败恢复请求的发送信道或信号为NR-PRACH,且NR-PRACH重传(除第一次传输外的其他次传输)携带波束失败恢复请求的发内容不同。终端标识为1的终端发生波束失败,且发现候选波束资源标识为0和1。这时,终端可利用NR-PRACH隐式发送终端标识和候选波束资源标识至网络设备侧。网络侧可通过预配置的NR-PRACH资源识别终端标识1,以及根据预分配的NR-PRACH资源分组确定候选波束资源标识0和1。进一步地,由于NR-PRACH携带资源能力有限,初次传输时,终端可通过NR-PRACH将终端标识1和候选波束资源标识0发送至网络设备侧;第一次重传时可通过NR-PRACH将终端标识1和候选波束资源标识1发送至网络设备侧。
本公开实施例的波束失败处理方法中,网络设备为发送波束失败恢复请求配置NR-PRACH资源配置信息和NR-PUCCH资源配置信息,并在终端接入时将NR-PRACH资源配置信息和NR-PUCCH资源配置信息发送给终端,并根据实时的资源占用情况向终端发送用于指示终端是通过NR-PRACH发送还是通过NR-PUCCH发送波束失败恢复请求的第一指示信息,以使终端在检测到波束失败时,根据第一指示信息、NR-PRACH资源配置信息和/或NR-PUCCH资源配置信息,确定发送波束失败恢复请求的目标传输资源,并通过该目标传输资源向网络设备发送相应的波束失败恢复请求,有效提高了波束失败恢复的效率,增强了高频通信链路传输可靠性。
