技术领域
本申请涉及通信领域,并且更具体地,涉及一种测量方法、终端设备和接入网设备。
背景技术
在现有的长期演进(long term evolution,LTE)技术中,在进行小区测量时,规定了一个控制终端设备对邻小区进行测量的起、停阈值,当服务小区的信号的测量值小于该阈值时,即服务小区的信号质量较差时,终端设备才会启动邻小区测量,而在服务小区的信号的测量值大于该阈值时,即服务小区的信号质量足够好时,终端设备一般会停止对邻小区的测量,达到省电的目的。
随着技术的逐渐发展,第四代移动通信技术(4th-generation wireless telephone technology,4G)已经进入规模商用阶段,面向未来的第五代移动通信技术(5th-generation wireless telephone technology,5G)也已经成为了全球研发的热点,移动互联网和物联网作为未来通信发展的主要驱动力,使得5G业务呈现多样化,为了提高5G业务中信号的传输速率,5G领域中将采用高频传输的方法,在采用高频传输时,引入了波束的概念,相应的,在5G领域中,要进行类似于LTE技术中的小区测量时,测量粒度需要更加精细化,所以,现有的LTE技术中基于小区粒度的测量方法已经不再适用于5G领域,因此,需要寻求一种适用于5G领域中的测量方法,以实现5G领域中波束的测量,从而实现为终端设备选择通信质量好的波束作为服务波束,保证通信的畅通。

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
图1所示为本申请实施例的一种测量方法100的示意性流程图,如图1所示,该方法100包括以下步骤。
110,终端设备接收接入网设备发送的第一消息。
该第一消息包括测量类型信息,该测量类型信息用于指示第一测量粒度,该第一测量粒度可以为小区测量粒度或波束测量粒度中的一种。
应理解,在测量粒度为波束测量粒度时,该波束可以指一个波束,也可以指多个波束形成的波束组或者发送接收点(transmission reception point,TRP),因此,在第一测量粒度为波束测量粒度时,实际上此时的测量粒度可能为波束测量粒度,波束组测量粒度或TRP测量粒度中的任一种。
应理解,在本申请实施例中,所述测量类型信息指示的第一测量粒度也可以是其他的测量粒度,本申请实施例仅以小区测量粒度和波束测量粒度为例对测量类型信息指示的测量粒度进行说明,但本申请实施例并不限定于此。
可选的,在一些实施例中,该第一消息可以为物理下行控制信道(physical downlink control channel,PDCCH)信息,或者也可以为媒体接入控制的控制单元(medium access control control element,MAC CE)信息。
可选的,在一些实施例中,该第一消息可以通过无线资源控制(radio resource control,RRC)的连接重配置消息携带,由接入网设备发送给终端设备,也可以通过其他RRC信令携带,由接入网设备发送给终端设备,本申请实施例对此不做限定。
在本申请实施例中,该测量方法指的是对小区或波束的参考信号进行测量的方法,具体的,在测量粒度为小区测量粒度时,该测量方法可以指对一个或多个小区中的参考信号接收功率(reference signal receiving power,RSRP)进行测量的方法和/或对参考信号接收质量(reference signal receiving quality,RSRQ)进行测量的方法;在测量粒度为波束测量粒度时,该测量方法可以指对一个或多个波束的RSRP进行测量的方法和/或对一个或多个波束的RSRQ进行测量的方法。
120,终端设备获取第一测量粒度对应的测量对象的测量值。
在本申请实施例中,引入了用于指示不同测量粒度的测量类型信息,使得终端设备对该测量类型信息对应的不同的测量对象进行测量,可以实现波束粒度的测量,使得测量粒度更加精细化,测量结果更加准确。
应理解,在本申请实施例中,即可以实现当前LTE技术中的小区粒度的测量,也可以实现波束粒度的测量,至于具体为哪种测量方式,可以根据接入网设备向终端设备配置的测量类型信息指示的第一测量粒度而确定。
还应理解,在测量类型信息指示的测量粒度为小区测量粒度时,该测量方法与现有的LTE技术中的小区测量方法基本相同,本申请实施例对此不做重点介绍,本申请实施例主要针对于测量类型信息指示的第一测量粒度为波束测量粒度的测量方法进行重点的描述。
可选的,该第一消息还可以包括第一测量粒度对应的测量门限值,该测量门限值与现有技术中的测量门限值的作用相同,用于与终端设备所在当前服务小区或当前服务波束的测量值进行比较,确定是否需要对其他小区或其他波束进行测量。
但是,在本申请实施例中,对于不同的测量粒度,该测量门限值可以不同,例如,在第一测量粒度为小区测量粒度时,测量门限值对应小区测量门限值,在第一测量粒度为波束测量粒度时,测量门限值对应波束测量门限值,该小区测量门限值与波束测量门限值可以不同,当然也可以存在这两个值相同的情况,本申请实施例对此不作限定。
可选的,该测量门限值为当前服务小区或当前服务波束的测量门限值,其他小区和其他波束可以不设置测量门限值。
可选的,在第一测量粒度为波束测量粒度时,该第一消息还包括一个或多个波束的波束标识,该波束标识用于指示不同的波束,该一个或多个波束指的是波束中除当前服务波束之外的其他波束。
应理解,该波束标识还用于使终端设备知道终端设备需要测量的波束的相关信息,例如,终端设备需要测量的波束的载波频率或频点,测量的带宽,频率偏移值和/或一些其他的可以用于指示波束的指示信息,通过该波束标识可以使终端设备知道如何对波束进行测量以及测量的频点是多少等信息。
可选的,该第一消息也可以包括当前服务波束的波束标识。
具体的,在终端设备需要对波束进行测量时,终端设备需要首先知道自己要测量的是哪个波束,对于当前服务波束,终端设备可以根据当前服务波束的波束标识确定当前的服务波束,该当前服务波束的波束标识可以是接入网设备通过第一消息发送给终端设备的,也可以是终端设备自己确定的,对于除当前服务波束之外的其他一个或多个波束,终端设备需要首先接收接入网设备配置的其他一个或多个波束的波束标识,根据该波束标识,对相应的波束进行测量。
可选的,在第一测量粒度为小区测量粒度时,该第一消息可以包括当前服务小区的小区标识以及除当前服务小区之外的其他小区的小区标识,该小区标识用于指示不同的小区,以便于终端设备知道需要如何对小区进行测量,以及测量的载波频率或频点,测量的带宽,频率偏移值等。
可选的,该第一消息还可以包括测量对象,在第一测量粒度为波束测量粒度时,该测量对象可以包括当前服务波束,也可以包括除当前服务波束之外的其他一个或多个波束。
也就是说,该第一消息包含的测量对象可以为当前服务波束的参考信号,也可以为除当前服务波束之外的其他一个或多个波束的参考信号。
可选的,该参考信号可以称为波束参考信号(beam reference signal,BRS),该BRS可以是信道状态信息参考信号(channel state information reference signal,CSI-RS),也可以是解调参考信号(demodulation reference signal,DM-RS),还可以是同步信号块(synchronization signal block,SS block),或者其他的参考信号,本申请实施例不限定于此。
可选的,终端设备对该当前服务波束的参考信号进行测量,得到的测量值为第一测量值,对除当前服务波束之外的其他一个或多个波束中的部分或全部波束的参考信号进行测量,得到的测量值为第二测量值。
应理解,由于对除当前服务波束之外的其他一个或多个波束中的部分或全部波束的参考信号进行测量得到第二测量值,所以该第二测量值可以为一个或多个值。
相应的,步骤120即终端设备获取第一测量粒度对应的测量对象的测量值可以包括:终端设备首先对当前服务波束的参考信号进行测量,获得当前服务波束的第一测量值,在该第一测量值小于或等于波束测量门限值时,终端设备需要对除当前服务波束之外的其他一个或多个波束中的部分或全部波束的参考信号进行测量,获得第二测量值。
可选的,在第一测量粒度为小区测量粒度时,该测量对象为小区参考信号(cell-specific  reference signal,CRS)。
可选的,在一些实施例中,该第一消息还可以包括测量报告配置信息,测量标识,测量量配置信息中的至少一种。
可选的,在一些实施例中,在第一测量粒度为波束测量时,测量报告配置信息用于指示终端设备在测量报告中发送N个波束的每个波束的测量值和/或该N个波束的测量值的合并值。
可选的,在一些实施例中,该N的个数由接入网设备进行配置,N为大于或等于1的正整数。
应理解,该N个波束的测量值的合并值为终端设备通过第一预设方式得到的数值,该第一预设方式可以为现有技术中的多种方式,例如,该第一预设方式可以是将所述N个测量值中每个测量进行加权求和,得到该合并值,或者该第一预设方式还可以是求取所述N个测量值的平均值,得到该合并值。
还应理解,该N个波束的测量值可以包括第一测量值和第二测量值,即可以是当前服务波束的测量值,也可以是除当前服务波束之外的其他波束的测量值。
可选的,在一些实施例中,终端设备可以通过多种方式获得该测量值,例如,终端设备可以通过层2合并和/或层2滤波的方式,例如,层2可以为媒体介入控制(medium access control,MAC)层,无线链路控制(radio link control,RLC)层或分组数据汇聚协议(packet data convergence protocol,PDCP)层,获得当前服务波束的BRS的测量值以及除当前服务波束之外的其他波束的BRS的测量值。
应理解,该测量报告中包含的N个波束的测量值可以是终端设备自己选择的结果,例如,终端设备选择所有的波束中测量值最大的前N个波束的测量值;也可以是终端设备根据接入网设备预先配置的第一预设条件选择的结果,例如,该第一预设条件可以是该N个波束中每个波束的测量值大于或等于第一阈值,该第一阈值可以由接入网设备进行配置。
可选的,在测量值大于或等于第一阈值对应的波束的个数多于N个时,可以取测量值大于或等于第一预设阈值对应的波束中的前N个波束的测量值作为测量报告的内容。
应理解,在测量粒度为波束测量时,终端设备在向接入网设备上报测量结果时,可以将选择的N个波束中每个波束的测量值上报给接入网设备,以便于接入网设备根据该测量值确定是否对当前服务波束进行切换,即测量报告配置信息指示终端设备在测量报告中发送N个波束中每个波束的测量值;终端设备也可以将该N个波束的测量值进行合并,合并为一个值之后,将该合并值上报给接入网设备,即测量报告配置信息指示终端设备在测量报告中发送该N个波束的测量值的合并值,至于终端设备将该N个波束的测量值进行合并得到合并值的方法,可以为现有技术中的多种方法中的任一种,例如,可以是对该N个测量值进行加权求和或者求该N个测量值的平均值,本申请实施例对比不做限定,终端设备还可以将该N个波束的测量值以及该N个波束的测量值的合并值同时上报给接入网设备,即测量报告配置信息还可以指示终端设备在测量报告中发送该N个波束中每个波束的测量值以及该N个波束的测量值的合并值。
可选的,在第一测量粒度为波束测量粒度,该波束实际为包括多个波束的波束组时,该测量报告配置信息可以指示终端设备在测量报告中发送M个波束的测量值以及该M个波束所在的波束组中每个波束的测量值。
可选的,在测量粒度实际为波束组测量粒度时,该测量报告配置信息还可以指示终端设备在测量报告中发送M个波束的测量值以及M个波束所在的波束组中每个波束的测量值的合并值。
可选的,在一些实施例中,该M的个数由接入网设备进行配置,M为大于或等于1的正整数。
可选的,该M个波束所在波束组中每个波束的测量值的合并值可以通过第二预设方式计算得到。
可选的,在一些实施例中,该第二预设方式可以为现有技术中的多种方式,例如,该第二预设方式可以是将所述M个测量值中每个测量进行加权求和,得到该合并值,或者该第二预设方式还可以是求取所述M个测量值的平均值,得到该合并值。
例如,接入网设备向终端设备配置的M的个数为3,且该3个波束中有2个波束来自第一波束组,另一个波束来自第二波束组,此时,终端设备向接入网设备上报的测量报告中包含该3个波束的测量值以及该3个波束所在的第一波束组和第二波束组中每个波束的测量值,或者终端设备向接入网设备上报的测量报告中包含3个波束的测量值以及该3个波束所在的第一波束组中每个波束的测量值得合并值以及该3个波束所在的第二波束组中每个波束的测量值的合并值。
可选的,在测量粒度实际为波束组测量粒度时,该测量报告配置信息还可以指示终端设备在测量报告中发送M个波束的测量值以及所有的波束组中每个波束的测量值。
可选的,在测量粒度实际为波束组测量粒度时,该测量报告配置信息还可以指示终端设备在测量报告中发送M个波束的测量值以及所有波束组中每个波束的测量值的合并值。
可选的,该所有波束组中每个波束的测量值的合并值可以通过第三预设方式计算得到。
可选的,在一些实施例中,该第三预设方式可以为现有技术中的多种方式,例如,该第三预设方式可以是将所述所有小区的波束组中每个波束的测量值进行加权求和,得到该合并值,或者该第三预设方式还可以是求取所述所有小区的波束组中每个波束的测量值的平均值,得到该合并值。
例如,接入网设备向终端设备配置的M的个数为3,当前总共有4个波束组,此时,终端设备向接入网设备上报的测量报告中包含这4个波束组中的测量值最大的3个波束的测量值以及当前存在的4个波束组中每个波束的测量值,或者终端设备向接入网设备上报的测量报告中包含测量值最大的3个波束的测量值以及当前存在的4个波束组中每个波束的测量值的合并值。
应理解,该第一预设方式、第二预设方式以及第三预设方式可以为相同的计算方式,也可以为不同的计算方式,本申请实施例对此不作限定。
应理解,上述所有小区的波束组是指终端设备所在的服务小区以及除服务小区之外的其他小区中所有的波束组,即包括终端设备所在的当前服务波束组所在的服务小区中的波束组,也包括除当前服务小区之外的其他小区中的波束组。
应理解,在测量报告配置中,终端设备向接入网设备发送的测量报告中包含的当前服务波束组的测量值的个数与其他波束组的测量值的个数可以相同,也可以不同,本申请实施例对此不做限定。
可选的,在一些实施例中,该测量报告中包含的M个波束的测量值可以是终端设备自己选择的结果,也可以是终端设备根据接入网设备预先配置的第二预设条件选择的结果,例如,该第二预设条件可以是该M个波束中每个波束的测量值大于或等于第二阈值,该第二阈值可以由接入网设备进行配置。
可选的,在一些实施例中,该测量报告配置信息中还可以包括上报方式配置信息,该上报方式配置信息用于指示终端设备向接入网设备上报测量报告时的方式,该上报方式配置信息可以包括事件触发上报、周期上报以及事件触发周期上报等多种上报上式。
可选的,该第一消息中包含的测量标识用于指示测量对象与测量报告配置信息之间的对应关系,将测量对象与其相应的测量报告配置信息联系起来。
也就是说,在进行测量上报时,终端设备根据测量标识,采用相应的测量报告配置信息对测量标识中该测量报告配置信息对应的测量对象的测量值进行评估和上报。
而且,该测量标识还用于唯一标识不同空口的测量上报,也就是说接入网设备通过终端设备在测量报告中包含的测量标识,区分终端设备当前上报的是哪个小区或哪个波束的测量信息。
应理解,对于多个测量标识来说可能对应多个测量对象和同一个测量报告配置信息,也可能是多个测量标识对应一个测量对象和多个测量报告配置信息。
可选的,该第一消息中包含的测量量配置信息用于指示用于层3滤波的相关系数,包括同频以及异频测量所需的相关系数,可理解,相关系数用于对测量的测量值进行处理。
应理解,在第一测量粒度为小区测量粒度时,该第一消息中包含的测量报告配置信息、测量标识以及测量量信息与现有技术中的作用相同,为了简洁,在此不再赘述。
可选的,在一些实施例中,第一消息可以包含当前服务波束的信息以及除当前服务波束之外的其他波束的信息,在终端设备对当前服务波束进行测量之后,得到的第一测量值小于或等于测量门限值时,此时终端设备需要对其他波束进行测量,由于接入网向终端设备发送的第一消息中包含了其他波束的配置信息,终端设备可以根据该信息中的一个或多个波束的波束标识确定需要测量的其他波束,再根据其他配置信息,对其他波束进行测量,并将测量值根据测量报告配置信息,通过测量报告的形式发送给终端设备。
例如,接入网设备发送的第一消息中包含的测量类型信息指示的第一测量粒度为波束测量粒度,此时终端设备根据该第一测量粒度,对当前服务波束进行测量,得到第一测量值,在得到第一测量值之后,将该第一测量值与第一消息中测量门限值进行比较,在第一测量值小于或等于测量门限值时,根据第一消息中包含的其他一个或多个波束的波束标识,确定需要测量的其他一个或多个波束,并对该其他一个或多个波束中的部分或全部波束进行测量,得到第二测量值,再根据测量报告配置信息,配置该测量报告,并将配置好的测量报告发送给接入网设备。
应理解,在测量值大于或等于其对应的测量门限值时,例如,当前服务小区的测量值大于或等于小区测量门限值或当前服务波束的测量值大于或等于波束测量门限值时,可以不对其他小区或其他波束进行测量,从而可以减少不必要的测量,提高了测量的效率,节省了能量。
可选的,在一些实施例中,第一消息中可以仅包括与当前服务波束相关的信息,例如,第一消息中可以仅包括测量类型信息以及测量类型信息指示的第一测量粒度对应的测量 对象、测量门限值等信息,在这种情况下,终端设备在对第一测量粒度对应的测量对象进行测量,得到第一测量值之后,将该第一测量值与第一消息中包含该第一测量粒度对应的测量门限值进行比较,在第一测量值小于该测量门限值时,确定需要对除当前服务的小区或当前服务的波束之外的其他小区或其他波束进行测量,然而,此时,第一消息中不包含其他小区或其他波束的配置信息,终端设备需要向接入网设备请求其他小区或其他波束的配置信息。
例如,接入网设备向终端设备发送的第一消息中包括的测量类型信息指示的测量粒度为波束测量粒度,该第一消息中还包括当前服务波束的测量门限值、测量报告配置信息等信息,终端设备在接收到上述消息之后,根据第一消息中包含的测量类型信息指示的第一测量粒度,对当前服务波束进行测量,获得第一测量值,在获得第一测量值之后,终端设备将该第一测量值与测量门限值进行比较,以确定是否需要对其他波束进行测量。
由于接入网设备向终端设备发送的第一消息中仅包括当前服务波束的配置信息,在第一测量值小于测量门限值时,终端设备需要对除当前服务波束之外的其他一个或多个波束中的部分或全部波束进行测量,然而,接入网设备并未向终端设备发送其他波束的配置信息,此时,终端设备可以向接入网设备发送配置请求消息,请求接入网设备向终端设备发送除当前服务波束之外的其他波束的配置信息。
在接入网设备接收到终端设备发送的配置请求消息之后,向终端设备发送第二消息,该第二消息包含其他一个或多个波束的波束标识,以及其他一个或多个波束的其他配置信息,例如,测量报告配置信息、测量量配置信息等等。
应理解,在第一测量粒度为小区测量粒度时,接入网设备根据终端设备发送的配置请求消息,向终端设备发送的第二消息中包括一个或多个其他小区的小区标识,该小区标识用于使终端设备识别其需要测量的其他小区,以及该一个或多个小区的其他配置信息。
接入网设备向终端设备发送该第二消息包括两种个情况:
一、接入网设备在向终端设备发送第一消息时,已经配置了该第二消息,但未将该第二消息与第一消息一起发送给终端设备。
在这种情况下,接入网设备在接收到终端设备发送的配置请求消息之后,可以直接将该第二消息发送给终端设备,以便终端设备对其他波束进行测量。
二、接入网设备在向终端设备发送第一消息时,并未配置第二消息。
在这种情况下,接入网设备在接收到终端设备发送的配置请求消息之后,可以先配置该第二消息,在配置了第二消息之后,再将该第二消息发送给终端设备。
可选的,该第二消息可以为物理下行控制信道(physical downlink control channel,PDCCH)信息,或者也可以为媒体接入控制的控制单元(medium access control control element,MAC CE)信息,或者还可以为无线资源控制(radio resource control,RRC)信息。
可选地,该配置请求消息可以为物理下行控制信道(physical downlink control channel,PDCCH)信息,或者也可以为媒体接入控制的控制单元(medium access control control element,MAC CE)信息,或者还可以为无线资源控制(radio resource control,RRC)信息或者是按需系统消息请求on-demand SI request;其中on-demand SI request可以通过随机接入的Msg1或Msg3发送。
应理解,在接入网设备向终端设备只发送当前服务小区或当前服务波束的第一消息时,终端设备可以将当前服务小区或当前服务波束的测量值与对应的测量门限值进行比较,在测量值小于测量门限值时,需要对其他小区或其他波束进行测量,此时,再向接入网设备发送配置请求消息,请求接入网设备给终端设备进行配置,即实现按需配置,从而节省了信令开销。
例如,当前的测量粒度为波束测量粒度,接入网设备在刚开始进行测量信息配置时,既配置了当前服务波束的测量配置信息,又配置了除当前服务波束之外的其他波束的测量配置信息,但是考虑到当前终端设备的能力等因素,例如,当前终端设备处于静止状态,该终端设备移动到其他波束的范围内的概率极小,因此,为了节省信令开销,接入网设备并未向终端设备发送其他波束的配置信息,在当前服务波束的测量值小于测量门限值时,例如,当终端设备由静止状态变为移动状态时,当前服务波束的信号质量对该终端设备来说不是很好,需要将当前服务波束切换至一个信号质量较好的目标波束上,此时,需要对除当前服务波束之外的其他波束进行测量,然而,由于接入网设备并未向终端设备配置其他波束的配置信息,所以,终端设备可以向接入网设备发送配置请求消息,以请求接入网设备向终端设备配置其他波束的配置信息。
可选的,在一些实施例中,终端设备在获得测量值(包括第一测量值和第二测量值)之后,根据接入网设备发送的测量报告配置信息,向接入网设备发送测量报告。
可选的,在第一测量粒度为波束测量粒度,且波束为一个波束时,该测量报告中包括N个测量值和/或N的测量值的合并值,该N个测量值与N个波束一一对应。
可选的,该N的个数由接入网设备配置,且该N个测量值大于或等于第一阈值。
可选的,在第一测量粒度为波束测量粒度,且波束包括多个波束时,该测量报告还可以包括M个波束中每个波束的测量值以及该M个波束所在的波束组中每个波束的测量值或者包括M个波束中每个波束的测量值以及该M个波束所在的波束组中每个波束的测量值的合并值。
可选的,在第一测量粒度为波束测量粒度,且波束包括多个波束时,该测量报告可以包括M个波束中每个波束的测量值以及所有的波束组中每个波束的测量值或者包括M个波束中每个波束的测量值以及该所有的波束组中每个波束的测量值的合并值。
可选的,在一些实施例中,接入网设备在接收到终端设备发送的测量报告之后,根据该测量报告和/或接入网设备预先制定的切换机制,向终端设备发送第三消息,该第三消息包括切换指示信息,以指示终端设备将当前服务小区或当前服务波束切换至该切换指示信息指示的目标小区或目标波束。
可选的,该第三消息可以为PDCCH信息或者MAC CE信息或者RRC消息。
应理解,本申请实施例主要对第一测量粒度为波束测量粒度的测量方法进行了详细的描述,在第一测量粒度为小区测量粒度时其测量方法与上述方法相同或相似,为了简洁,不再赘述。
在本申请实施例中,通过引入不同的测量类型,可以实现不同粒度的测量,使得测量粒度更加精细化,测量结果更加准确。

210,终端设备接收接入网设备发送的第一消息。
该第一消息包括测量类型信息,该测量类型信息用于指示第一测量粒度,该第一测量粒度为波束测量粒度。
应理解,在第一测量粒度为波束测量粒度时,该波束可以指一个波束也可以指多个波束形成的波束组或TRP,因此,在第一测量粒度为波束测量粒度时,实际上此时的测量粒度可能为波束测量粒度,波束组测量粒度以及TRP测量粒度中的一种。
可选的,该第一消息中包括测量类型信息、当前服务波束相关的信息以及除当前服务波束之外的其他一个或多个波束相关的信息。

可选的,该第一消息还可以包括第一测量粒度对应的测量门限值,该测量门限值与现有技术中的测量门限值的作用相同,用于与终端设备所在当前服务小区或当前服务波束的测量值进行比较,确定是否需要对其他小区或其他波束进行测量。
但是,在本申请实施例中,对于不同的测量粒度,该测量门限值可以不同,例如,在第一测量粒度为小区测量粒度时,测量门限值对应小区测量门限值,在第一测量粒度为波束测量粒度时,测量门限值对应波束测量门限值,该小区测量门限值与波束测量门限值可以不同,当然也可以存在这两个值相同的情况,本申请实施例对此不作限定。

也就是说,该第一消息包含的测量对象可以为当前服务波束的参考信号,也可以为除当前服务波束之外的其他一个或多个波束的参考信号。
可选的,该参考信号可以称为波束参考信号(beam reference signal,BRS),该BRS可以是信道状态信息参考信号(channel state information reference signal,CSI-RS),也可以是解调参考信号(demodulation reference signal,DM-RS),还可以是同步信号块(synchronization signal block,SS block),或者其他的参考信号,本申请实施例不限定于此。
可选的,终端设备对该当前服务波束的参考信号进行测量,得到的测量值为第一测量值,对除当前服务波束之外的其他一个或多个波束中的部分或全部波束的参考信号进行测 量,得到的测量值为第二测量值。
应理解,由于对除当前服务波束之外的其他一个或多个波束中的部分或全部波束的参考信号进行测量得到第二测量值,所以该第二测量值可以为一个或多个值。
可选的,在一些实施例中,在第一测量粒度为小区测量粒度时,测量对象为小区参考信号,既包括当前服务小区的参考信号,也包括除当前服务小区之外的其他小区的参考信号。
可选的,在一些实施例中,该第一消息还可以包括测量报告配置信息,测量标识,测量量配置信息中的至少一种。

可选的,在一些实施例中,该N的个数由接入网设备进行配置,N为大于或等于1的正整数。
应理解,该N个波束的测量值的合并值为终端设备通过第一预设方式得到的数值,该第一预设方式可以为现有技术中的多种方式,例如,该第一预设方式可以是将所述N个测量值中每个测量进行加权求和,得到该合并值,或者该第一预设方式还可以是求取所述N个测量值的平均值,得到该合并值。
还应理解,该N个波束的测量值可以包括第一测量值和第二测量值,即可以是当前服务波束的测量值,也可以是除当前服务波束之外的其他波束的测量值。
可选的,在一些实施例中,终端设备可以通过多种方式获得该测量值,例如,终端设备可以通过层2合并和/或层2滤波的方式,例如,层2可以为媒体介入控制(medium access control,MAC)层,无线链路控制(radio link control,RLC)层或分组数据汇聚协议(packet data convergence protocol,PDCP)层,获得当前服务波束的BRS的测量值以及除当前服务波束之外的其他波束的BRS的测量值。

可选的,在本申请实施例中,在终端设备进行测量之前,终端设备需要进行随机接入。
在进行随机接入时,可以分为以下几个步骤:
1)随机接入资源配置和选择
可选的,在一些实施例中,终端设备首先需要进行下行同步,接收接入网设备广播的广播消息,该广播消息中包含下行波束和随机接入资源配置之间的对应关系
可选的,在一些实施例中,该随机接入资源配置包括随机接入过程中所需的时频资源和/或前导码划分信息等。
可选的,在一些实施例中,在随机接入过程中,终端设备首先按照接入网设备发送的测量配置信息进行下行波束测量,并根据测量结果确定该终端设备接收随机接入响应(random access response,RAR)消息时的信号质量最好的下行波束,然后通过接收的广播消息中包含的下行波束和随机接入资源配置之间的对应关系,确定随机接入的资源配置,该随机接入的资源配置包括随机接入的前导码和/或随机接入过程所需的时频资源,并在相应的随机接入的时频资源上发送前导码,接入网设备在随机接入时频资源上接收到前导码后,根据接收的该前导码所在的下行波束和随机接入资源配置之间的对应关系,确 定发送RAR消息的下行波束,该RAR消息中携带发送Msg3的上行定时提前(timing advance,TA)以及发送Msg3的上行资源(例如,时频资源)等。
其中,Msg3是一类信息的统称,不同随机接入场景中,Msg3中包含的内容不同,可选地,该Msg3可以包含RRC消息,例如:RRC连接建立请求消息或者RRC连接重建消息,或者按需系统消息请求(on-demand SI request)等,或者,Msg3还可以包含MAC CE,例如:用于上报缓存状态报告BSR的MAC CE,或者用于上报波束失败恢复请求(beam failure recovery request)的MAC CE等。
可选地,在一些实施例中,终端设备接收的广播消息中包含的下行波束和随机接入资源之间的对应关系可以是接入网设备配置的SS block和随机接入时频资源和/或一组随机接入前导码之间的对应关系。
可选地,在一些实施例中,终端设备接收的广播消息中包含的下行波束和随机接入资源之间的对应关系还可以是接入网设备配置的CSI-RS和随机接入时频资源和/或一组随机接入前导码之间的对应关系。
可选地,在一些实施例中,终端设备接收的切换消息中包含的下行波束和随机接入资源之间的对应关系可以是接入网设备配置的SS block和随机接入时频资源和/或一组随机接入前导码之间的对应关系,以及用于随机接入的专用资源,专用资源包括时/频/码域资源。
可选地,在一些实施例中,终端设备接收的切换消息中包含的下行波束和随机接入资源之间的对应关系还可以是接入网设备配置的CSI-RS和随机接入时频资源和/或一组随机接入前导码之间的对应关系,以及用于随机接入的专用资源,专用资源包括时/频/码域资源。
上述实施例中,时域资源可能是一个或多个随机接入传输机会(RACH transmission occasions);频域资源可能是一个或多个物理随机接入资源PRACH位置,PRACH位置可以是连续的,也可以是不连续的;码域资源可能是一个或多个前导码preamble;
2)Msg2
(a)Msg2的内容
Msg2为接入网设备向终端设备发送的随机接入响应RAR消息其中,该RAR消息至少包括定时提前TA、上行授权UL grant、临时的小区无线网络标识(temporary cell radio network temporary identifier,TC-RNTI)等信息。
可选的,终端设备可以根据接入网设备发送的Msg2携带的信息(例如,上述的定时提前TA、上行授权资源UL grant等信息),向接入网设备发送Msg3。
可选地,在用Msg1来发送按需系统消息on-demand SI的情况下,RAR内容可以为空,即RAR消息中不携带任何指示信息,此时,终端设备无需进行Msg3和Msg4步骤。
可选地,在5G潜在的随机接入应用场景中(即利用Msg1发送波束失败恢复请求beam failure recovery request),RAR中指示的UL grant的比特域可能大于LTE中对应比特域;此时,终端设备可利用RAR携带的TA以及UL grant来发送波束测量报告等信息。
可选地,在某些非竞争随机接入场景中,如RRC连接态,有下行数据到达,但上行失步,需重新进行随机接入时,由于此时不需要发送Msg3,故RAR中可不携带UL grant。
可选地,在某些非竞争随机接入场景中,如切换场景,终端设备已经分配了C-RNTI, 不需要接入网设备再携带TC-RNTI,故此时RAR中可不携带TC-RNTI。
(b)RAR接收窗口启动
现有技术中,在发完Msg1后,终端设备会在经历一段固定时间后,开启RAR接收窗,对于LTE而言,该接收窗的固定时间为3个子帧;如果终端设备是基于蜂窝网的窄带物联网(narrow band internet of things,NB-IoT)设备,则在最后一个前导码重复后的子帧+41个子帧后,开启RAR接收窗。
可选地,若下行波束与前导码和/或PRACH之间存在对应关系,则终端设备需要先确定接收RAR消息的下行波束,然后在Msg1发完后一段时间后开启RAR消息接收窗,并在RAR消息接收窗口持续时间内监听此下行波束,当监听到属于自己的RAR消息(RAR对应的子载波中RAPID与自己所发的前导码相同)后,可利用RAR消息中携带的信息向接入网设备发送Msg3,发送Msg3的波束和发送Msg1的波束可相同,也可以不同,取决于UE实现。
可选地,若终端设备允许在一个RAR内向接入网设备发送多个Msg1时,终端设备开启RAR接收窗的可能情况为:
1:在终端设备发完第一个Msg1后,就开启RAR接收窗;
2:在终端设备发完最后一个Msg1后,才开启RAR接收窗;
3:每发送一个Msg1,就开启对应的RAR接收窗;
(c)监听RAR使用的RA-RNTI
针对(b)终端设备允许在一个RAR内发送多个Msg1情况,用于监听RAR的RA-RNTI可能的情况为:
1:使用一个default RA-RNTI;
2:利用现有RA-RNTI计算公式,计算出多次Msg1发送时频资源位置对应的RA-RNTI,利用多个RA-RNTI来监听RAR。
(d)RAR接收
针对一个RAR窗口内可回复多个Msg1情况,接入网设备在收到多个Msg1时,可以只回复一个,或者针对每一个Msg1都回复一个RAR;对应地,终端设备只要收到一个RAR就停止接收RAR,认为成功接收到RAR。
3)Msg3和Msg4
Msg3是一类信息的统称,不同随机接入场景中,Msg3中包含的内容不同,例如,
可选地,该Msg3可以包含RRC消息,例如:RRC连接建立请求消息或者RRC连接重建消息或者按需系统消息请求(on-demand SI request)等,或者,Msg3可以包含MAC CE,例如:用于上报缓存状态报告BSR的MAC CE,或者用于上报波束失败恢复请(beam failure recovery request)的MAC CE等。
可选地,若终端设备在接收到属于自己的RAR消息之前,允许在多个波束上发送Msg1,则RAR消息中可携带信号质量最好的上行波束的信息,此时,发送Msg3时可采用此最好上行波束发送。反之,若RAR消息中没有携带信号质量最好的波束的信息,发送Msg3适用的上行波束取决于UE实现。
当Msg3发送成功,即在发送Msg3过程中没有出现冲突也没有报错,则认为终端设备随机接入成功,可进入连接态;反之,当Msg3发送失败,接入网设备会通过Msg4发 送竞争决议,告知随机接入失败,需要重新进行随机接入,其中,该Msg4为接入网设备向终端设备发送的竞争决议消息,该竞争决议消息用于告知终端设备随机接入失败,需要终端设备重新进行随机接入。
4)重新进行随机接入
当UE重新发起随机接入时,需要按照预定的功率爬坡机制提升Msg1发送功率,从而提高随机接入成功概率,不同波束对应的功率爬坡参数可能相同,也可能不同,功率爬坡参数主要是功率爬坡步长powerRampingStep,即每次重新发起随机接入时提升的功率幅度,和/或最大发送功率(当达到最大发送功率时,维持最大发送功率,不再爬坡),以及前导码目标接收功率preambleInitialReceivedTargetPower等,DELTA_PREAMBLE为一个与功率爬坡相关的偏移量参数,与前导码发送格式有关,可以通过查表获得。
重新发送Msg1时的波束可能和前一次发送Msg1时采用的波束相同,也可以不同,取决于UE实现,即UE可能进行波束的切换,也可能不进行波束的切换。
在提升Msg1的发送功率时,终端设备需要维护一个与功率爬坡相关的计数器POWER_POWERING_COUNTER,该计数器可以和前导码发送次数的计数器PREAMBLE_TRANSMISSION_COUNTER相同,或者不同。
下面根据是否区分功率爬坡计数器和前导码发送计数器,以及是否考虑RAR窗口内多Msg1发送,分几种情况来分别说明功率爬坡机制:
情况一:分别维护两个计数器,不考虑RAR窗口内多Msg1发送
(1)参数维护
可选的,在一种可能的实现方式中,终端设备分别维护与功率爬坡相关的计数器POWER_POWERING_COUNTER和与前导码发送次数相关的计数器PREAMBLE_TRANSMISSION_COUNTER,两者作用不同,与功率爬坡相关的计数器用于终端设备计算功率,而与前导码发送次数相关的计数器用于判断是否超过最大前导码发送次数限制,若超过,需要指示上层出现随机接入问题。
随机接入过程初始化时,将两个计数器均设置为0,之后按照发送Msg1的上行波束
是否改变,来维护计数器值的增加,当随机接入过程结束(随机接入成功或达到最大前导码发送次数的限制而随机接入失败)后,上述两个计数器的值重置为0。
(2)功率爬坡公式
按照功率爬坡公式可计算出前导码目标接收功率PREAMBLE_RECEIVED_TARGET_POWER,功率爬坡公式可为:
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(POWER_POWERING_CO UNTER–1)*powerRampingStep     (1)
其中,preambleInitialReceivedTargetPower为前导码初始发送功率,powerRampingStep为功率爬坡步长,上述两个参数可由接入网设备通过系统消息发给终端设备。
DELTA_PREAMBLE和前导码发送格式(Preamble Format)有关,Preamble Format可通过随机接入配置中参数prach-ConfigIndex予以指示。
例如,以LTE为例,表1所示为一个关于DELTA_PREAMBLE取值的表格,根据前导码发送格式查找该表格,可以获得DELTA_PREAMBLE的取值。
表1 关于DELTA_PREAMBLE取值
前导码发送格式 DELTA_PREAMBLE取值
0 0dB
1 0dB
2 -3dB
3 -3dB
4 8dB
如功率爬坡公式(1)所示,可以根据不同的与功率爬坡相关的参数,确定Msg1的发送功率,从而可以使终端设备获知当前Msg1的发送功率,以便于终端设备根据该Msg1的发送功率重新进行随机接入。
当发送Msg1的波束与前一次发送Msg1时采用的波束相同时,功率爬坡使用的功率爬坡相关的计数(POWER_POWERING_COUNTER)的的值增加1,并按照此波束对应的功率爬坡步长来提升功率,当重传波束发生改变时,功率爬坡使用的功率爬坡相关的计数器(POWER_POWERING_COUNTER)的值不变,并按照重传波束对应的功率爬坡步长来提升功率。
上述功率爬坡方法引入一个与功率爬坡相关的计数器(POWER_POWERING_COUNTER),此计数器用于功率爬坡计算,重用过去LTE的功率爬坡公式,标准改动相对小,但需在协议中增加计数器描述。
此外,可选地,由于功率爬坡相关的计数器(POWER_POWERING_COUNTER)是一个与上行波束改变有关的变量,功率爬坡公式还可以为:
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(POWER_POWERING_COUNTER+sgn(x)–1)*powerRampingStep    (2)
其中,x可取0或1两个值,0表示发送Msg1的波束与前一次发送Msg1时采用的波束相同;1表示发送Msg1的波束与前一次发送Msg1时采用的波束不同。
Msg1发送波束变化判断
Msg1发送波束是否变化取决于终端设备实现,终端设备判断Msg1波束发生变化,可能是MAC实体收到物理层PHY指示或者上层的波束变化指示,从而在MAC层按照上述功率爬坡公式进行计算前导码目标接收功率,并将计算出的前导码目标接收功率连同发送Msg1所选的物理随机接入信道(physical random access channel,PRACH),相关无线网络临时标识(radio network tempory identity,RA-RNTI),前导码指示(preamble index)、和/或所选发送Msg1的上行波束等指示给物理层。
情况二:维护1个counter,不考虑RAR窗口内多Msg1发送。
(1)参数维护
参数维护与情况一相同,这里不再赘述
(2)功率爬坡公式
可选的,在一种可能的实现方式中,终端设备维护一个前导码发送计数器PREAMBLE_TRANSMISSION_COUNTER,而此计数器不仅可以用于终端设备计算功率,而且此计数器可用于判断是否超过最大前导码发送次数限制,若超过,需要指示上层出现随机接入问题。这种在随机接入过程中使用一个计数器的情况,对标准改动较小,但需要在协议中增加相应描述;此时,功率爬坡公式为:
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_TRANSMISSION_COUNTER–1)*powerRampingStep    (3)
在标准中对应的描述为:当发送Msg1的波束与前一次发送Msg1时采用的波束相同时,功率爬坡使用的功率爬坡相关的参数PREAMBLE_TRANSMISSION_COUNTER的值增加1,并按照此波束对应的功率爬坡步长来提升功率,当重传波束发生改变时,功率爬坡使用的功率爬坡相关的参数PREAMBLE_TRANSMISSION_COUNTER的值不变,并按照重传波束对应的功率爬坡步长来提升功率。而对于前导码发送次数的描述为:前导码首次发送,Msg1前导码发送次数加1,后续每次发送前导码,不管发送Msg1波束和前一次波束是否相同,前导码发送次数都在前一次前导码发送次数的基础上加1,这样在标准中,体现不出前导码次数的变量计数,用文字描述代替,当前导码次数超过最大前导码发送限制时,指示上层出现随机接入问题。
(3)Msg1发送波束变化判断
Msg1发送波束变化判断,与情况一中对应部分相同,这里不再赘述。
情况三:分别维护两个计数器,考虑RAR窗口内多Msg1发送的情况。
可选地,若终端设备在接收到属于自己的RAR消息之前,允许在多个波束上发送多个Msg1,多个Msg1发送有多种发送形式,发送波束可能相同,也可能不同,具体的,可以包括以下几种情况:
在相同波束上,利用不同时频资源发送相同前导码,或者
在相同波束上,利用相同时频资源发送不同前导码;或者
在不同波束上,同一时刻,利用不同频域资源发送相同前导码;或者
在不同波束上,同一时刻,利用相同频域资源发送不同前导码。
不论多个Msg1的发送是上述哪种形式,也不论波束是否发生改变,功率爬坡相关的参数PREAMBLE_TRANSMISSION_COUNTER的值保持不变,对应的,终端设备在接收到属于自己的RAR消息之前,发送多个Msg1的功率可能是完全相同,或者是功率爬坡相关的参数PREAMBLE_TRANSMISSION_COUNTER的值保持不变,但按照发送波束对应的功率爬坡步长来设置发送功率。
对应地,功率爬坡不同的方法,对应不同的功率爬坡公式。
方法一:重用LTE的功率爬坡公式,但对RAR窗口内多次Msg1发送增加修正值,保证一个RAR窗口内多次Msg1发送功率相同;
方法二:同一个RAR窗口内多次Msg1发送,不论Msg1的发送波束是否发生变化,功率爬坡counter值不变;相应地,公式重用LTE,但需要增加标准描述;
方法三:同一个RAR窗口内,发送多次Msg1,每次Msg1发送,发送波束变化与否,会影响功率爬坡counter值:波束变化,counter不变,波束不变,counter加1;然后把算好的功率告知PHY,PHY利用路损等计算出发送功率后,会和最大发送功率进行比较,从而求得实际发送功率,当实际发送功率达到最大值后,不论Msg1波束是否发生变化,都保持最大发送功率不变。
在方法一重用LTE功率爬坡+多Msg1情况功率修正值的情况下。
(1)参数维护
可选的,在一种可能的实现方式中,终端设备分别维护功率爬坡计数器 POWER_POWERING_COUNTER和前导码发送计数器PREAMBLE_TRANSMISSION_COUNTER,两者作用不同,功率爬坡counter用于终端设备计算功率,而前导码发送counter用于判断是否超过最大前导码发送次数限制,若超过,需要指示上层出现随机接入问题。
随机接入过程初始化时,将两个counter设置为0,之后按照发送Msg1的UL beam是否改变来维护counter值的增加,当随机接入过程结束(随机接入成功或达到最大前导码发送限制而随机接入失败)后,将两个counter值重置为0;
此外,维护一个RAR窗口内Msg1发送次数变量,将一个RAR窗口内UE的Msg1发送定义为一次发送尝试机会,此变量相当于是UE获得一次发送尝试机会后,可以在RAR窗口内发送的次数,此变量可表示为numPreambleAttemptperRARwindow。
(2)功率爬坡公式
此方法中,按照功率爬坡公式可计算出前导码目标接收功率PREAMBLE_RECEIVED_TARGET_POWER,功率爬坡公式可为:
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(POWER_POWERING_COUNTER–1)*powerRampingStep    (4)
如果是一个RAR窗口内允许发送多个Msg1case,则对PREAMBLE_RECEIVED_TARGET_POWER取值做进一步修正,在此情况下,前导码目标接收功率PREAMBLE_RECEIVED_TARGET_POWER可为:
PREAMBLE_RECEIVED_TARGET_POWER–f(numPreambleAttemptperRARwindow)
这里,f(.)表示一个函数,可选的,该函数可为对数函数形式,举例如下:
PREAMBLE_RECEIVED_TARGET_POWER–10*log10(numPreambleAttemptperRARwindow)    (5)
如上所述的公式(5),可以根据不同的与功率爬坡相关的参数以及一个RAR窗口内Msg1发送次数变量,确定Msg1的发送功率,从而可以使终端设备获知当前Msg1的发送功率,以便于终端设备根据该Msg1的发送功率重新进行随机接入。对于上述公式中功率爬坡counter取值PREAMBLE_RECEIVED_TARGET_POWER描述同情况一,不再赘述。
在方法二同一个RAR窗口内多次Msg1发送,不论Msg1的发送波束是否发生变化,功率爬坡counter值不变;相应地,公式重用LTE,但需要增加标准描述的情况下。
此方法中,按照功率爬坡公式可计算出前导码目标接收功率PREAMBLE_RECEIVED_TARGET_POWER,功率爬坡公式可为:
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(POWER_POWERING_COUNTER–1)*powerRampingStep    (6)
在同一次随机接入尝试机会内,即相同RAR窗口内,多次(numPreambleAttemptperRARwindow)的Msg1发送,无论Msg1波束是否变化,用于功率爬坡的counter值不变,而功率爬坡的计数器只在相同RAR窗口内多次Msg1都发完,重新获得随机接入尝试机会时,功率爬坡的计数器值变化有如下几种选择。
1:当重新获得随机接入尝试机会时,功率爬坡的counter值加1;
2:当重新获得随机接入尝试机会时,以首个Msg1发送的波束变化作为功率爬坡counter的变化依据,即当首个Msg1的发送波束与前一次随机接入尝试机会内的首个Msg1 发送波束相同时,功率爬坡使用的功率爬坡相关的参数POWER_POWERING_COUNTER的值增加1,并按照此波束对应的功率爬坡步长来提升功率,当首个Msg1的发送波束与前一次随机接入尝试机会内的首个Msg1发送波束不同时,功率爬坡使用的功率爬坡相关的参数POWER_POWERING_COUNTER的值不变,并按照重传波束对应的功率爬坡步长来提升功率。
3:当重新获得随机接入尝试机会时,以Msg1的发送方式pattern(多个Msg1的发送形式)是否变化作为功率爬坡计数器的变化依据,即当Msg1的发送pattern和前一次随机接入尝试机会的Msg1发送pattern一样时,计数器值保持不变,而当相邻两次Msg1发送pattern不同时,计数器值加1;这里,Msg1发送pattern可理解为在一次随机接入尝试机会内对发送Msg1次数,以及每次Msg1发送使用的时域、频域以及beam等相关配置;
在方法三同一个RAR窗口内,发送多次Msg1,每次Msg1发送,发送波束变化与否,会影响功率爬坡计数器值:波束变化,计数器不变,波束不变,计数器加1;然后把算好的功率告知PHY,PHY利用路损等计算出发送功率后,会和最大发送功率进行比较,从而求得实际发送功率,当实际发送功率达到最大值后,不论Msg1波束是否发生变化,都保持最大发送功率不变的情况下。
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(POWER_POWERING_COUNTER–1)*powerRampingStep    (7)
上述公式中,即便是多次Msg1发送,每次Msg1发送都根据发送波束是否和前一次Msg1发送波束是否相同来判断,如果当发送Msg1的波束与前一次发送Msg1时采用的波束相同时,功率爬坡使用的功率爬坡相关的参数POWER_POWERING_COUNTER的值增加1,并按照此波束对应的功率爬坡步长来提升功率,当重传波束发生改变时,功率爬坡使用的功率爬坡相关的参数POWER_POWERING_COUNTER的值不变,并按照重传波束对应的功率爬坡步长来提升功率。
Msg1发送波束是否改变取决于终端设备实现,终端设备判断Msg1波束发生变化,可能是MAC实体收到物理层PHY指示或者上层的波束变化指示,从而在MAC层按照上述功率爬坡公式进行计算前导码目标接收功率PREAMBLE_RECEIVED_TARGET_POWER,并将计算出的PREAMBLE_RECEIVED_TARGET_POWER连同发送Msg1所选的PRACH,相关RA-RNTI,preamble index和/或所选发送Msg1的UL beam等指示给物理层。物理层收到PREAMBLE_RECEIVED_TARGET_POWER后,在考虑路损(pathloss)等,会按照自己的计算方法,计算出一个发送功率,并将该发送功率和Msg1最大发送功率进行比较,当达到最大前导码发送功率后,保持最大发送发送功率不变。
情况四:维护1个计数器,考虑RAR窗口内多Msg1发送
UE维护一个计数器,即前导码发送计数器,此外,还维护一个参数,用于指示一次随机接入尝试机会(同一个RAR窗口内)可以发送的Msg1个数numPreambleAttemptperRARwindow;在同一个RAR窗口内,不论Msg1的发送波束是否发生变化,都保持多个Msg1的发送功率不变,对应功率爬坡公式如下:
preambleInitialReceivedTargetPower+DELTA_PREAMBLE+(floor(PREAMBLE_TRANSMISSION_COUNTER/numPreambleAttemptperRARwindow)–1) *powerRampingStep    (8)
其中,在同一个RAR窗口(一次随机接入尝试机会内)内,每发送一次Msg1,前导码发送次数PREAMBLE_TRANSMISSION_COUNTER都增加1,相应地,在重新进入另一个随机接入尝试机会后,功率爬坡中的counter值变化要依赖于Msg1发送波束是否发生改变;可能的选择的情况如下。
1:当重新获得随机接入尝试机会时,以首个Msg1发送的波束变化作为功率爬坡counter的变化依据,即当首个Msg1的发送波束与前一次随机接入尝试机会内的首个Msg1发送波束相同时,功率爬坡使用的功率爬坡相关的参数PREAMBLE_TRANSMISSION_COUNTER的值加1,并按照此波束对应的功率爬坡步长来提升功率,当首个Msg1的发送波束与前一次随机接入尝试机会内的首个Msg1发送波束不同时,功率爬坡使用的功率爬坡相关的参数PREAMBLE_TRANSMISSION_COUNTER的值设置为PREAMBLE_TRANSMISSION_COUNTER-numPreambleAttemptperRARwindow,并按照重传波束对应的功率爬坡步长来提升功率。
2:当重新获得随机接入尝试机会时,以Msg1的发送方式pattern(多个Msg1的发送形式)是否变化作为功率爬坡counter的变化依据,即当Msg1的发送pattern和前一次随机接入尝试机会的Msg1发送pattern一样时,counter值设置为PREAMBLE_TRANSMISSION_COUNTER-numPreambleAttemptperRARwindow,而当相邻两次Msg1发送pattern不同时,PREAMBLE_TRANSMISSION_COUNTER值加1;这里,Msg1发送pattern可理解为在一次随机接入尝试机会内对发送Msg1次数,以及每次Msg1发送使用的时域、频域以及beam等相关配置;
5)随机接入过程相关的其他内容
5G中讨论随机接入可能用于请求按需系统消息(on-demand SI),而on-demand SI的请求可能通过Msg1/Msg3来发送。
(1)Msg1发送按需系统消息请求(on-demand SI request)的情况
在此情况下,某个随机接入前导码可以用于请求发送多个on-demand SI消息,当接入网设备接收到该前导码,根据前导码和on-demand SI之间的对应关系可获知终端设备请求的系统消息,终端设备和接入网设备之间只需要交互on-demand SI请求和on-demand SI确认即可,因此,基于Msg1发送on-demand SI request的情况只包括随机接入的Msg1和Msg2,如图3所示。
图4为LTE媒体接入控制协议数据单元(media access control protocol data unit,MAC PDU)结构示意图,由图4可知,一个MAC PDU由MAC头(MAC header)以及一个或多个MAC RAR组成,MAC header中包括2种类型的MAC子头(MAC sub-header),即E/T/RAPID MAC sub-header和E/T/R/R/BI MAC subheader,2个MAC subheader的示意图分别如图5和图6所示,此外,每个E/T/RAPID MAC subheader与一个RAR对应,RAR结构如图7所示,RAR中携带用于发送Msg3的定时提前TA、上行资源授权(UL grant)以及临时的小区无线网络标识(cell-radio network temporary identity,temporary C-RNTI)等。
在基于Msg1发送on-demand SI的情况下,只需要Msg1和Msg2,后续的Msg3和 Msg4可不发送。因此,RAR中可能不需要TA、UL grant以及TC-RNTI等指示信息,即相当于是没有RAR部分。
故在此情况下,随机接入响应协议数据单元(random access reception protocol data unit,RAR PDU)回复时,针对on-demand SI request对应的前导码回复,与传统LTE不同;在这种情况下,MAC RAR和MAC RAR sub-header可以不一一对应,在MAC PDU中可以只包括MAC RAR子头(MAC RAR sub-header)而不包括对应的MAC RAR,这里的MAC RAR sub-header中包括前导码标识,当终端设备监听到某个MAC sub-header中包含的前导码指示与自身发送on-demand SI请求时使用的前导码相同时,认为on-demand SI request发送成功,此时,MAC sub-header相当于是on-demand SI request的一个确认,后续根据系统消息无线网络标识(system information-radio network temporary identity,SI-RNTI)来接收接入网设备发送的on-demand SI。
可选地,在一些实施例中,针对不同的on-demand SI接收可区分不同的SI-RNTI。
可选地,为了提升on-demand SI request的成功发送概率,终端设备可以在收到属于自己的回复(即RAR subheader)前可以发送多个Msg1,多个Msg1的发送与前面描述相同,在此不再赘述。
终端设备在收到属于自己的RAR sub-header后,可以知道on-demand SI request已经发送成功,后续接收接入网设备发送的on-demand SI,RAR sub-header中包括前导码标识,但具体格式依赖于5G中前导码设计,在此不做任何限定。
(2)Msg3发送on-demand SI request的情况。
图8为基于Msg3发送on-demand SI request的示意图,在此情况下:
Step 1:终端设备通过Msg3发送on-demand SI请求,Msg3可携带终端设备的标识信息和请求的系统消息块(system information block,SIB)的指示列表,其中:
所述Msg3可携带终端设备的标识信息,其中终端设备的标识信息需区分终端设备是否处于不同模式,例如,
(1)对于空闲态模式的终端设备(idle mode UE),终端设备的标识信息可以为小区无线网络标识(cell-radio network temporary identity,C-RNTI);
(2)对于不活跃模式的终端设备(inactive mode UE),终端设备的标识信息可以为Resume-like ID;
(3)对于连接态模式的终端设备(connected mode UE),终端设备的标识信息可以为C-RNTI。
所述Msg3可携带请求的SIB的指示列表,SIB指示方式可以为bitmap形式或者显示使用系统信息块索引(SIB index(s))指示;
这里,bitmap形式可理解为固定二进制bit位,每个bit位对应一种SIB,用0或1来指示终端设备是否请求对应的SIB;例如,采用3个二进制来分别指示SIB1、SIB2和SIB3,001表示终端设备请求SIB3,而101表示终端设备请求SIB1和SIB3,其他类比,不再赘述。
Step 2:终端设备发送Msg3完成后,监听Msg4是否有Msg3中发送的SI-request被接入网设备成功接收的确认指示信息,UE监听Msg4使用的RNTI可以为一下中的任一种:
(1)对于DLE mode UE,可用Msg2中的C-RNTI来指示;
(2)对于Inactive mode UE,可用存储在UE接入层上下文(AS context)中的C-RNTI来指示;
(3)对于Connected mode UE,可用C-RNTI来指示。
可选地,在一些实施例中,对于空闲态终端设备,终端设备在Msg3中发完系统请求消息后,利用Msg2中C-RNTI以及SI-RNTI来监听,直到成功接收到请求的系统消息后,才停止监听。
可选地,在一些实施例中,Msg4也可以用于发送Msg3中发送的SIB(s),接入网设备可通过无线资源控制(radio resource control,RRC)信令来发送请求的SIB(s)。
可选地,如前所述,不同随机接入场景下,Msg3中内容可能不同,Msg3可引入新的MAC CE信息用于指示on-demand SI的发送,当接入网设备成功收到Msg3,或者接入网设备知道终端设备需要的on-demand SI是哪些时,相应地,在接入网设备向终端设备发送下行消息时,该下行消息可能引入新的MAC CE来表述终端设备需要的on-demand SI。在这种情况下,当终端设备收到on-demand SI,终端设备认为Msg4对应的竞争决议成功,这种情况与LTE技术中不一样的是LTE只有收到属于自己的竞争决议才认为竞争决议成功。
Step 3:当终端设备未成功接收到SI时,终端设备会重新发送Msg1或Msg3,以便终端设备重新获取系统消息SI,即重新发送on-demand SI请求直到达到最大次数限制。
可选地,on-demand SI请求对应的最大次数可能为前导码最大发送次数,也可能是Msg3最大发送次数,如Msg3对应的混合自动请求重传次数(hybrid automatic repeat request,HARQ)。
此外,on-demand SI对应的最大重发次数限制可能和随机接入其他场景对应的最大重发次数限制相同,也可以不同。
Step 4:基于Msg1/Msg3发送on-demand SI,达到最大随机接入次数后还不能成功接收SI时,处于不同状态的UE,可能采取的操作不同:
1)对于DLE mode UE,可能进入连接态去接收on-demand SI,或者选择其他合适的小区进行小区选择;
2)对于Connected mode UE,当超过最大次数限制后,执行小区选择,向其他合适小区请求SI。
可选的,在一些实施例中,在进行随机接入时,终端设备可以预先获知自己的当前服务波束。
可选的,在一些实施例中,在终端设备通过随机接入过程进入连接状态之后,终端设备也可以获知自己的当前服务波束。
可选的,在一些实施例中,终端设备可以根据当前服务波束的标识信息,确定该终端设备的当前服务波束。
220,终端设备对当前服务波束进行测量,得到第一测量值。
可选的,在一些实施例中,终端设备可以通过层2合并或层2滤波的方式获得该第一测量值。
应理解,由于终端设备对当前服务波束进行测量,获得的第一测量值,所以第一测量 值为当前服务波束的测量值。
230,将该第一测量值与测量门限值进行比较,确定是否需要对其他波束进行测量。
可选的,在一些实施例中,终端设备将第一测量值与测量门限值进行比较,在第一测量值小于预设测量门限值时,终端设备确定需要对除当前服务波数之外的其他一个或多个波束的部分或全部波束的参考信号进行测量。
可选的,在一些实施例中,若第一测量值大于测量门限值,则表示当前服务波束的信号质量比较好,不需要对终端设备所在的当前服务波束进行切换,则流程结束。
240,在第一测量值小于或等于测量门限值的情况下,终端设备对其他波束进行测量,获得第二测量值。
可选的,在一些实施例中,终端设备可以通过层2合并或层2滤波的方式获得该第二测量值。
可选的,该第二测量值为终端设备对其他一个或多个波束的部分或全部波束的参考信号进行测量得到的测量值,所以该第二测量值可以为一个值也可以为多个值。
