具体实施方式
下面结合附图及实施例对本申请再作进一步详细的描述。
相关技术中,NR系统中的接入过程包括:首先,终端通过小区搜索,即进行SSB搜索,以获取到小区同步;接着,获取到小区同步后,终端通过SSB中的PBCH,获取到CORESET#0,也即initial BWP,并在CORESET#0上进一步获取系统消息,并在对应的初始上行BWP(initial UL BWP)上进行相应的随机接入操作;如果小区内只在一个频点上发送了SSB,则所有的终端通过该initial UL BWP进行接入,当存在大量终端时,可能造成接入资源的碰撞,导致终端接入失败。
在NR系统中,为了提升覆盖性能,引入了增补上行(SUL,Supplementary UpLink)载波,作为上行的补充载波,在SIB1中广播,终端在初始接入的过程中,根据测得的下行信号强度判断是使用SUL进行随机接入还是普通的上行载波接入(这种接入技术可以称为SUL技术)。具体地,当信道的参考信号接收功率(RSRP)低于一定门限则使用SUL的上行BWP进行随机接入,否则使用普通载波的上行载波进行接入。
当引入NR light终端后,大量终端同时接入系统可能带来的接入资源碰撞问题需要进行解决,虽然SUL技术能够在一定程度上缓解上行随机接入的拥塞,但是由于其对初始接入终端的分流主要处在小区边缘,对于小区中心的终端则无能为力;另一方面,SUL技术要求一个额外的载波作为补充载波,在进行部署时会带来额外的要求。
综上所述,在NR系统中,当大量用户同时接入网络时会存在拥塞的问题。
基于此,在本申请的各种实施例中,网络设备向终端发送指示信息,以达到终端分流的目的。
其中,实际应用时,所述网络设备可以是基站,比如下一代节点B(gNB) 等。
本申请实施例提供了一种信息传输方法,应用于网络设备,包括:
向终端发送指示信息;所述指示信息指示以下至少之一:
至少一个时域和/或频域资源,其中,所述至少一个时域和/或频域资源用于使所述终端确定自身接收信息和/或发送信息的时域和/或频域资源;
所述指示信息对应的时域和/或频域资源是否允许终端接入;
所述指示信息对应的时域和/或频域资源允许接入的终端类型;
所述指示信息对应的时域和/或频域资源支持的至少一种终端处理能力,即所述对应的时域和/或频域资源是否支持某种终端处理能力;
所述指示信息对应的时域和/或频域资源允许接入的终端类型优先级;
至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源。
其中,实际应用时,当所述指示信息指示上述信息中至少两个信息时,可以通过一个消息发送所述至少两个信息,也可以通过不同消息来发送所述至少两个信息。
所述接收信息和/或发送信息的时域和/或频域资源是指:所述终端接收信息的时域和/或频域资源和/或所述终端发送信息的时域和/或频域资源。
在一实施例中,所述时域和/或频域资源包括BWP。
在一实施例中,若所述指示信息指示至少一个时域和/或频域资源,即在所述指示信息指示至少一个时域和/或频域资源的情况下,所述指示信息的指示方式包括以下至少之一:
时域和/或频域资源对应的bitmap;
时域和/或频域资源的索引;
频域资源的RIV。
其中,实际应用时,可以采用资源分配类型指示时域和/或频域资源,也可以称为资源分配方式类型,可以包含资源分配类型0(英文可以表达为Type 0)和资源分配类型1(英文可以表达为type 1)。这里,资源分配方式类型0和类型1的具体方式可参照相关技术理解。资源分配方式类型0是一种通过bitmap指示时域和/或频域资源的方式。资源分配方式类型1是通过一个RIV值(对应一个虚拟资源块(RB)的起始位置和连续分配的RB的个数),来指示频域资源。
在一实施例中,若所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型,即在所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型的情况下,所述指示信息的指示方式包含以下之一:
终端类型的bitmap指示;
终端类型的索引。
在一实施例中,若所述指示信息指示所述指示信息对应的时域和/或频 域资源支持的至少一种终端处理能力,即在所述指示信息指示所述指示信息对应的时域和/或频域资源支持的至少一种终端处理能力的情况下,所述指示信息的指示方式包含以下之一:
终端处理能力的bitmap;
终端处理能力的索引。
在一实施例中,若所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型优先级的情况下,即在所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型优先级的情况下,一种实现方式是:所述指示信息具体指示所述指示信息对应的时域和/或频域资源允许接入的至少一种终端类型的优先级(即每种终端类型的优先级);另一种实现方式是所述指示信息可以具体指示所述指示信息对应的时域和/或频域资源允许接入的高优先级的终端类型。
在一实施例中,若所述指示信息指示至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源,即在所述指示信息指示至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源的情况下,所述指示信息的指示方式包含以下之一:
时域和/或频域资源的比特位图;
时域和/或频域资源的索引;
频域资源的RIV。
其中,所述每种终端类型作为高优先级的时域和/或频域资源是指:每种终端类型所对应的高优先级服务的时域和/或频域资源。
实际应用时,在NR系统中,如图1所示,在物理层,终端通过如下的流程接入到载波:
首先,通过小区搜索,获取到SSB。
接着,通过SSB中的PBCH获取到CORESET#0,也即initial BWP,终端在CORESET#0中按照PBCH中配置的type0-PDCCH的参数检测type0-PDCCH搜索空间,获取到调度SIB1的控制信道,从而获取到对应的SIB1消息,获得小区公共配置信息。
其中,调度SIB1的控制信道通过SI-RNTI加扰,承载调度SIB1PDSCH的调度相关信息。
小区公共配置信息可以包括上行和下行公共配置信息,时分双工(TDD)配置)等。其中,在下行公共配置信息中,可以包括频域的信息,初始下行BWP(initial DL BWP)的配置信息;在上行公共配置信息中,可以包括上行载波的频域信息及initial UL BWP的配置信息,在initial UL BWP中会配置随机接入参数信息,用于终端发起随机接入使用。
为了将终端分流到其他时域和/或频域资源上,而不是集中在初始小区搜索的initial BWP上,可以从SIB1开始分流,或者从随机接入开始分流,或者从type0-PDCCH的接收就开始分流。
基于此,在一实施例中,可以通过以下方式之一向所述终端发送指示信息:
通过由SI-RNTI进行CRC加扰的控制信道向所述终端发送所述指示信息;
通过系统消息向所述终端发送所述指示信息;
通过SSB向所述终端发送所述指示信息。
其中,实际应用时,考虑到携带指示信息的承载对应的比特数有限,所以指示信息是按照一定的颗粒度进行时域和/或频域资源指示的,可以有如下两种指示的颗粒度,以S表示指示的颗粒度:
第一种,初始SSB指示的initial DL BWP的带宽,也就是说,所述指示信息进行时域和/或频域资源指示的颗粒度为初始BWP对应的带宽;
第二种,预定义的带宽,例如20MHz,10MHz等;也就是说,所述指示信息进行时域和/或频域资源指示的颗粒度为预定义的带宽。
其中,实际应用时,可以根据需要选择上述两种颗粒度中的任意一种。
所述指示信息对应的时域和/或频域资源是指:承载所述指示信息的载体所对应的时域和/或频域资源,举个例子来说,由SI-RNTI进行CRC加扰的控制信道、系统消息(比如SIB1)、SSB均可承载在initial BWP上,这个initial BWP即为所述指示信息对应的时域和/或频域资源,此时所述指示信息指示这个initial BWP是否允许终端接入,或者指示这个initial BWP允许接入的终端类型,或者指示这个initial BWP允许接入的终端类型优先级,或者指示这个initial BWP作为特定终端类型的高优先级服务BWP。
下面描述向所述终端发送所述指示信息的具体实现过程。
首先,详细描述通过由SI-RNTI进行CRC加扰的控制信道向所述终端发送所述指示信息的实现过程。
所述由SI-RNTI进行CRC加扰的控制信道向所述终端发送所述指示信息,可以理解为通过在调度系统信息的控制信道中(经SI-RNTI加扰的控制信道)承载所述指示信息,也就是说,通过系统信息对应的无线网络临时标识(RNTI)加扰的控制信道传输所述指示信息。
具体地,在一实施例中,通过type0-PDCCH公共搜索空间中由SI-RNTI进行CRC加扰的控制信道向所述终端发送所述指示信息。
这里,实际应用时,可以通过调度SIB1的控制信道承载,即通过调度SIB1的控制信道向所述终端发送所述指示信息。
实际应用时,在调度SIB1的物理下行控制信道(PDCCH)中,有15比特的预留比特,甚至更多的预留比特,比如17比特,可以用来指示其他时域和/或频域资源的情况。
另一方面,考虑到比特数有限,所以指示信息是按照一定的颗粒度进行时域和/或频域资源指示的,可以有如下两种指示的颗粒度,以S表示指示的颗粒度:
第一种,初始SSB指示的initial DL BWP的带宽,也就是说,所述指示信息进行时域和/或频域资源指示的颗粒度为初始BWP对应的带宽;
第二种,预定义的带宽,例如20MHz,10MHz等;也就是说,所述指示信息进行时域和/或频域资源指示的颗粒度为预定义的带宽。
其中,实际应用时,可以根据需要选择上述两种颗粒度中的任意一种。
当所述指示信息指示至少一个时域和/或频域资源时,所述指示信息指示的方式包括以下方式至少之一:
通过时域和/或频域资源对应的bitmap指示;
通过时域和/或频域资源的索引指示;
通过频域资源的RIV指示。
其中,当以bitmap的形式指示时,分别指示以S为颗粒度的时域和/或频域资源位置。不同的比特指示不同的时域和/或频域资源的位置是否可用。
示例性地,以BWP为例,考虑到低频支持的最大系统带宽为100MHz,以S=20MHz为例,共有5个不重叠的BWP。考虑到当前BWP有可能是频率最低的BWP,对于比当前BWP频率高的BWP,需要4比特指示其他4个BWP,当前BWP也有可能是频率最高的BWP,则比当前BWP频率低的BWP,需要4比特指示其他4个BWP;加之,当前BWP也可以被指示是否能够被低成本终端使用,总共需要9比特的bitmap指示,9比特的中间比特对应当前比特,终端可判断出其他BWP的位置,及对应的BWP是否可以使用。图2示例了三种指示情况,分别对应示例(case)A,case B和case C。其中,case A中,当前BWP位于系统带宽划分的以S为颗粒度的频率最高的BWP;case B中,当前BWP位于系统带宽划分的以S为颗粒度的频率最低的BWP;case C中,当前BWP位于系统带宽划分的以S为颗粒度的中间频率的BWP。当然,对于终端来说,并不知道当前BWP所在的位置,只需要以中间比特作为参照,作为当前BWP的指示,识别比当前BWP更高频率或者更低频率上是否有BWP可以使用。在图2中,
Figure PCTCN2021075886-appb-000001
表示在系统带宽之外,
Figure PCTCN2021075886-appb-000002
表示可用,
Figure PCTCN2021075886-appb-000003
表示不可用。
这里,对于NR light的终端,如果只需要考虑除当前BWP以外的BWP是否可用,不考虑当前BWP,则只需要8比特即可实现bitmap的指示。
当通过索引的方式指示或者索引和bitmap的方式指示时,以BWP为例,考虑到当前BWP在整个系统带宽中一共有5种可能的位置,则需要3比特完成位置指示,例如000表示第一个位置,001表示第2个位置,即指示位置索引;另外,还需要指示出来哪些BWP可以使用,则需要将5个BWP做排列组合(
Figure PCTCN2021075886-appb-000004
其中,
Figure PCTCN2021075886-appb-000005
表示Y个元素中取X个的可能取法,如果考虑全都不可用,则还有一种组合,因此共32种情况),或者直接以5bit的比特map指示是等效的,则加上在系统带宽中的5种可 能的3比特指示,共需要8比特。
如果当前BWP不能被NR light的终端使用,则要指示出来哪些BWP可以使用,只需要4比特,加上5种可能的位置3比特,则共需要7比特。比完全用bitmap的方式要少1比特。
当通过RIV指示时,在PDCCH中的预留比特(高位到低位或者低位到高位的顺序)承载RIV值指示每种终端类型对应的高优先级服务的频域资源。
当所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型时,也可以通过调度SIB1的PDCCH中预留的比特,来指示允许接入的终端类型。
此时,所述指示信息指示的方式包括以下方式之一:
通过终端类型的bitmap指示;
通过终端类型的索引指示。
其中,当以bitmap的形式指示时,不同的比特指示不同的终端类型的终端是否允许接入。
示例性地,假设NR light终端分了2种类型,加上eMBB/URLLC终端共有3种类型,此时可以采用3比特即可实现bitmap的指示,用于分别表示是否支持第一种类型、第二种类型及第三种类型终端,比如011表示允许第二种和第三种类型的终端接入;100表示只允许第一种类型终端接入。
当通过终端类型的索引指示时,可以为每种终端类型设置相应的索引,在PDCCH中的预留比特承载允许接入的终端类型的索引。
当所述指示信息指示所述指示信息所述指示信息对应的时域和/或频域资源支持的至少一种终端处理能力时,也可以通过调度SIB1的PDCCH中预留的比特,来指示支持的终端处理能力。
此时,所述指示信息指示的方式包含以下之一:
通过终端处理能力的bitmap指示;
通过终端处理能力的索引指示。
其中,当以bitmap的形式指示时,不同的比特指示是否支持不同的终端处理能力。
示例性地,假设R15、R16终端支持两种终端处理能力,如果为NR light终端引入了更低的终端处理能力3,在上述的指示信息中还可能指示是否支持终端处理能力3,此时可以采用3比特即可实现bitmap的指示,用于分别表示是否支持第一种终端处理能力、第二种终端处理能力及第三种终端处理能力,比如011表示支持第二种和第三种终端处理能力;100表示只支持第一种终端处理能力。
当通过终端处理能力的索引指示时,可以为每种终端类型设置相应的索引,在PDCCH中的预留比特承载支持的终端处理能力的索引。
当所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入 的终端类型优先级时,也可以通过调度SIB1的PDCCH中预留的比特,来指示允许接入的终端类型优先级。需要注意的是PDCCH的预留比特,在R15/16版本中是预留比特,当这些比特被赋予新的含义时,便不再是预留比特。
实际应用时,对于每种类型的终端定义一个优先级值,取值为0~P,0表示最低优先级,P表示最高优先级。示例性地,假设NR light(即RedCap)终端分了2种类型,加上普通终端(即eMBB/URLLC终端)共有3种类型,假设分别是A、B、C,可以根据需要设置:B的优先级值为2,A的优先级值为1,C的优先级值为0。当终端类型为A或C的终端收到该指示信息后,获知当前BWP中自己所属的终端类型并不是优先服务的,终端可以选择继续在该BWP上服务,也可以选择重新搜索寻找对应高优先级的BWP。
当然,实际应用时,两种终端类型具有相同的优先级,表示在当前时域和/或频域资源上均会被同等服务。本申请实施例对如何设置优先级值的过程不作限定。
当所述指示信息指示至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源(即最适合某种终端类型的时域和/或频域资源位置)时,也可以通过调度SIB1的PDCCH中预留的比特,来指示每种终端类型作为高优先级的时域和/或频域资源(例如BWP资源)。
此时,所述指示信息指示的方式包括以下方式之一:
通过时域和/或频域资源的bitmap指示;
通过时域和/或频域资源的索引指示;
通过频域资源的RIV指示。
其中,当以bitmap形式的指示时,每种终端类型对应一个时域和/或频域资源的bitmap,不同的比特指示不同的时域和/或频域资源是否是该终端类型对应的高优先级服务的时域和/或频域资源。示例性地,对于上述例子,指示当前BWP为终端类型B的高优先级BWP,其他终端类型在该BWP均不是最高优先级,即为低优先级,此时终端类型C和A的终端可以根据bitmap形式的指示,获知自身最高优先级服务的BWP。
当通过时域和/或频域资源的索引指示时,可以为每个时域和/或频域资源设置相应的索引,在PDCCH中的预留比特(高位到低位或者低位到高位的顺序)承载每种终端类型对应的高优先级服务的时域和/或频域资源的索引。
当通过RIV指示时,在PDCCH中的预留比特(高位到低位或者低位到高位的顺序)承载RIV值指示每种终端类型对应的高优先级服务的频域资源。
这里,需要说明的是:实际应用时,当网络设备发送了多个SSB用于终端接入,此时有些SSB对应的CORESET#0(用于传输type0-PDCCH的CORESET资源)的带宽较小,不想让NR eMBB终端和/或URLLC终端接 入,则可以在type0-PDCCH中的所述指示信息中指示对应的CORESET#0资源及其后续的广播消息等是否适用于某种类型的终端或者是否允许某种类型的终端接入。
接着,描述通过系统消息向所述终端发送所述指示信息的具体实现过程。
通过所述系统消息向所述终端发送所述指示信息,可以理解为通过系统消息(也可以称为系统信息)承载所述指示信息。
实际应用时,所述系统消息可以是SIB1或其他SIB。
图3为使用SIB1指示低成本终端(比如NR light终端)可以使用的BWP示意图,在这种情况下,接收SIB1消息都是在当前的BWP上,根据SIB指示的其可用的BWP,低成本终端在被指示的BWP上发起随机接入流程,即终端的随机接入被分布到了不同的BWP上,起到了分流的作用。随机接入流程包含Message1,Message2,Message3和Message4的传输,其中Message1和Message3是上行传输,终端发送信息;Message2和Message4是下行传输,终端接收信息。通过在SIB配置多个上、下行BWP对,即SIB1中配置了成对儿的ULBWP和DL BWP,可以是频分双工(FDD)的成对频谱,也可以是TDD的共中心频点的成对BWP,终端可以在确定的BWP对资源上进行随机接入的上下传输。
由于系统消息的传输承载在PDSCH上,对比特开销的要求不高,因此,与控制信道承载所述指示信息的方式类似地,所述指示信息的指示方式可以通过bitmap和索引的方式实现。具体地,
当所述指示信息指示至少一个时域和/或频域资源时,所述指示信息指示的方式包括以下方式至少之一:
通过时域和/或频域资源对应的bitmap指示;
通过时域和/或频域资源的索引指示;
通过频域资源的RIV指示。
示例性地,以BWP为例,考虑到低频支持的最大系统带宽为100MHz,以S=20MHz为例,共有5个不重叠的BWP。考虑到当前BWP有可能是频率最低的BWP,对于比当前BWP频率高的BWP,需要4比特指示其他4个BWP,当前BWP也有可能是频率最高的BWP,则比当前BWP频率低的BWP,需要4比特指示其他4个BWP;加之,当前BWP也可以被指示是否能够被低成本终端使用,总共需要9比特的bitmap指示,9比特的中间比特对应当前比特,终端可判断出其他BWP的位置,及对应的BWP是否可以使用。图2示例了三种指示情况,分别对应case A,case B和case C。其中,case A中,当前BWP位于系统带宽划分的以S为颗粒度的频率最高的BWP;case B中,当前BWP位于系统带宽划分的以S为颗粒度的频率最低的BWP;case C中,当前BWP位于系统带宽划分的以S为颗粒度的中间频率的BWP。当然,对于终端来说,并不知道当前BWP所在的位置, 只需要以中间比特作为参照,作为当前BWP的指示,识别比当前BWP更高频率或者更低频率上是否有BWP可以使用。
这里,对于NR light的终端,如果只需要考虑除当前BWP以外的BWP是否可用,不考虑当前BWP,则只需要8比特即可实现bitmap的指示。
当通过索引的方式指示或者索引和bitmap的方式指示时,以BWP为例,考虑到当前BWP在整个系统带宽中一共有5种可能的位置,则需要3比特完成位置指示,例如000表示第一个位置,001表示第2个位置,即指示位置索引;另外,还需要指示出来哪些BWP可以使用,则需要将5个BWP做排列组合(
Figure PCTCN2021075886-appb-000006
其中,
Figure PCTCN2021075886-appb-000007
表示Y个元素中取X个的可能性,如果考虑全都不可用,则还有一种组合,因此共32种情况),或者直接以5bit的比特map指示是等效的,则加上在系统带宽中的5种可能的3比特指示,共需要8比特。
如果当前BWP不能被NR light的终端使用,则要指示出来哪些BWP可以使用,只需要4比特,加上5种可能的位置3比特,则共需要7比特。比完全用bitmap的方式要少1比特。
当通过RIV指示时,在系统消息中(高位到低位或者低位到高位的顺序)通过RIV值承载每种终端类型对应的高优先级服务的频域资源。
当所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型时,也可以通过系统消息,来指示允许接入的终端类型。
此时,所述指示信息指示的方式包括以下方式之一:
通过终端类型的bitmap指示;
通过终端类型的索引指示。
其中,当以bitmap的形式指示时,不同的比特指示不同的终端类型的终端是否允许接入。
示例性地,假设NR light终端分了2种类型,加上eMBB/URLLC终端共有3种类型,此时可以采用3比特即可实现bitmap的指示,用于分别表示是否支持第一种类型、第二种类型及第三种类型终端,比如011表示允许第二种和第三种类型的终端接入;100表示只允许第一种类型终端接入。
当通过终端类型的索引指示时,可以为每种终端类型设置相应的索引,在系统消息中承载允许接入的终端类型的索引。
当所述指示信息指示所述指示信息所述指示信息对应的时域和/或频域资源支持的至少一种终端处理能力时,也可以通过系统消息,来指示支持的终端处理能力。
此时,所述指示信息指示的方式包含以下之一:
通过终端处理能力的bitmap指示;
通过终端处理能力的索引指示。
其中,当以bitmap的形式指示时,不同的比特指示是否支持不同的终端处理能力。
示例性地,假设R15、R16终端支持两种终端处理能力,如果为NR light终端引入了更低的终端处理能力3,在上述的指示信息中还可能指示是否支持终端处理能力3,此时可以采用3比特即可实现bitmap的指示,用于分别表示是否支持第一种终端处理能力、第二种终端处理能力及第三种终端处理能力,比如011表示支持第二种和第三种终端处理能力;100表示只支持第一种终端处理能力。
当通过终端处理能力的索引指示时,可以为每种终端类型设置相应的索引,在系统消息中承载支持的终端处理能力的索引。
当所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型优先级时,也可以通过系统消息,来指示允许接入的终端类型优先级。
实际应用时,对于每种类型的终端定义一个优先级值,取值为0~P,0表示最低优先级,P表示最高优先级。示例性地,假设NR light终端分了2种类型,加上普通终端(即eMBB/URLLC终端)共有3种类型,有三种终端类型,假设分别是A、B、C,可以根据需要设置:B的优先级值为2,A的优先级值为1,C的优先级值为。当终端类型为A或C的终端收到该指示信息后,获知当前BWP中自己所属的终端类型并不是优先服务的,终端可以选择继续在该BWP上服务,也可以选择重新搜索寻找对应高优先级的BWP。
当然,实际应用时,两种终端类型具有相同的优先级,表示在当前时域和/或频域资源上均会被同等服务。本申请实施例对如何设置优先级值的过程不作限定。
当所述指示信息指示至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源(即最适合某种终端类型的时域和/或频域资源位置)时,也可以通过系统消息,来指示支持的每种终端类型作为高优先级的时域和/或频域资源(比如BWP资源)。
此时,所述指示信息指示的方式包括以下方式之一:
通过时域和/或频域资源的bitmap指示;
通过时域和/或频域资源的索引指示;
通过频域资源的RIV指示。
其中,当以bitmap形式的指示时,每种终端类型对应一个时域和/或频域资源的bitmap,不同的比特指示不同的时域和/或频域资源是否是该终端类型对应的最高优先级服务的时域和/或频域资源。示例性地,对于上述例子,指示当前BWP为终端类型B的最高优先级BWP,其他终端类型在该BWP均不是最高优先级,即为低优先级,此时终端类型C和A的终端可以根据bitmap形式的指示,获知自身最高优先级服务的BWP。
当通过时域和/或频域资源的索引指示时,可以为每个时域和/或频域资源设置相应的索引,在系统消息中(从高位到低位或者低位到高位的顺序) 承载每种终端类型对应的最高优先级服务的时域和/或频域资源的索引。
当通过RIV指示时,在系统消息中(高位到低位或者低位到高位的顺序)承载RIV值指示每种终端类型对应的高优先级服务的频域资源。
这里,如前所述,所述终端通过接收SIB1消息获得小区公共配置信息,包括上行和下行公共配置信息,TDD配置等。其中,在下行公共配置信息中包括了频域的信息,initial DL BWP的配置信息;在上行公共配置信息中,包括了上行载波的频域信息及initial UL BWP的配置信息,在initial UL BWP中会配置随机接入参数信息,用于终端发起随机接入使用。终端在initial UL BWP发起随机接入,并在相应的initial DL BWP接收初始接入相关的下行信息。这里,在网络给终端配置其他BWP之前,在initial DL BWP和initial UL BWP上进行数据传输。
因此,当所述指示信息至少指示至少一个时域和/或频域资源时,可以以更详细的方式指示,具体有以下两种:
第一种指示方式,在SIB消息中,配置多套时域和/或频域资源的参数。也就是说,所述指示信息包含所述SIB1中携带的N个时域和/或频域资源位置及每个时域和/或频域资源对应的参数配置信息。
示例性地,相关技术中,在SIB1消息中,在下行公共配置信息中,会配置一套initial DL BWP的配置信息,在上行公共配置信息中,配置一套initial UL BWP的配置信息。在本申请实施例中,在下行公共配置信息和上行公共配置信息中分别配置多套的下行BWP(这些下行BWP可以称为initial DL BWP)和上行BWP(这些上行BWP可以称为initial UL BWP)相关的参数信息,例如对于上行BWP会配置:通用参数,随机接入信道(RACH)配置信息,上行业务信道(即物理上行共享信道(PUSCH))及上行公共控制信道(即物理上行控制信道(PUCCH))的公共配置信息等;对于下行BWP会配置:通用参数,下行控制信道(即PDCCH)公共配置信息,下行业务信道(即PDSCH)公共配置信息;额外地,还可分别配置每一个BWP是否支持NR light低成本终端,或者说支持某种终端能力或终端处理能力的终端。这样,NR light终端通过读取这些信息,根据自身的能力找到匹配的BWP进行随机接入,数据传输等操作。
例如,对获取到其他可以进行随机接入,进行数据传输的BWP。
这里,NR light终端只是一种终端能力的示意,也可以是其他类型的终端,例如降低了终端能力的终端,相比于eMBB/URLLC终端,使用了更少的天线,支持更小的带宽等。
在这种方式下,支持多套BWP中的每个BWP可以有BWP专属的参数配置,允许个性化的配置不同的BWP。例如随机接入配置,搜索空间配置等都可以不同。
第二种指示方式,在SIB1消息中,配置一套公共的时域和/或频域资源参数。
示例性地,仍然使用相关技术中SIB1中对于initial DLBWP和initial UL BWP的配置,只是可以配置不同的BWP的位置,这些BWP除了时域和/或频域资源位置不同,其他的用于终端接入的参数配置及下行检测的相关配置可以相同。
也就是说,所述指示信息包含所述SIB1中携带的N个时域和/或频域资源位置及公共的参数配置信息,公共的参数配置信息对于N个时域和/或频域资源位置确定的时域和/或频域资源均适用。
第二种指示方式能够节省信令开销。
其中,N为大于或等于1的整数。
实际应用时,根据需要选择上述任意一种指示方式。
实际应用时,SIB消息除了指示哪些时域和/或频域资源可以用于NR light终端的传输,同时还可以指示这些时域和/或频域资源支持的NR light终端的终端能力,当NR light的终端进一步划分了多种能力时,通过这种方式,能够让终端根据自己的能力找到匹配的时域和/或频域资源进行随机接入,数据传输等。
当所述指示信息的指示方式通过bitmap和索引的方式实现时,可以再增加相应的比特位(比如1比特),指示支持NR light的终端能力1或是终端能力2。
当所述指示信息的指示方式通过在SIB消息中配置参数的方式实现时,可以针对每个时域和/或频域资源,配置支持的终端能力。
通过使用时域和/或频域资源的framework,能够为不同能力的终端进行时域和/或频域资源专有(specific)的参数配置,能够更好地支持对应类型的终端(比如多进多出(MIMO layer),处理时长(processing time)等)
这里,实际应用时,当网络设备发送了多个SSB用于终端接入,此时有些SSB对应的CORESET#0(用于传输type0-PDCCH的CORESET资源)的带宽较小,不想让NR eMBB终端和/或URLLC终端接入,则可以在SIB1中的所述指示信息中指示对应的CORESET#0资源及其后续的广播消息等是否适用于某种类型的终端或者是否允许某种类型的终端接入。
最后,描述通过SSB向终端发送所述指示信息的具体实现过程。
通过SSB向所述终端发送所述指示信息,可以理解为通过SSB承载所述指示信息。
具体地,通过所述SSB的PBCH中的比特指示。
当最大SSB的个数小于或等于8时,在PBCH中有2位比特是预留的。这2位在最大SSB的个数为64时,与另一位比特一起指示SSB索引的高3位比特。也就是说,在FR1即6GHz以下频段,还有2比特未被使用。同时,主信息块(MIB)信息中,在PBCH中还有1比特未被使用。因此PBCH中有预留的3比特可以使用
因此,可以通过这两位预留比特指示其他的时域和/或频域资源,用于 NR light终端接入。2比特可以指示4种状态,例如分别指示以当前PBCH中pdcch-ConfigSIB1字段确定的CORESET#0,也即initial BWP的带宽(或以预定义带宽)为颗粒度的最多4个时域和/或频域资源。
基于此,在一实施例中,通过SSB向所述终端发送所述指示信息时,通过PBCH中的保留比特承载所述指示信息。
当所述指示信息指示至少一个时域和/或频域资源时,所述指示信息指示的方式包括以下方式至少之一:
通过时域和/或频域资源对应的bitmap指示;
通过时域和/或频域资源的索引指示。
示例性地,以BWP为例,当前SSB所对应的CORESET#0为20MHz带宽,指示的颗粒度为20MHz带宽,但是NR light终端的带宽为10MHz的情况,由于CORESET#0的带宽大于NR light终端的带宽,所以NR light终端无法接入,因此在指示的时候不需要包括这个BWP,通过2比特的bitmap指示,可以指示2个BWP,分别包括1个比CORESET#0的频率高的BWP和比其频率低的1个BWP,如图4所示。当然NR light终端的带宽也可以和CORESET#0的带宽相同。
当通过终端类型的索引指示时,可以为每种终端类型设置相应的索引,在PBCH中的预留比特承载允许接入的终端类型的索引。
当通过时域和/或频域资源的索引指示时,可以为每个时域和/或频域资源设置相应的索引,在SSB中(从高位到低位或者低位到高位的顺序)承载每种终端类型对应的最高优先级服务的时域和/或频域资源的索引。
当所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型时,也可以通过PBCH中预留的3比特来来指示允许接入的终端类型。
此时,所述指示信息指示的方式包括以下方式之一:
通过终端类型的bitmap指示;
通过终端类型的索引指示。
其中,当以bitmap的形式指示时,不同的比特指示不同的终端类型的终端是否允许接入。
示例性地,假设NR light终端分了2种类型,此时可以采用2比特即可实现bitmap的指示,用于分别表示是否支持第一种类型、第二种类型终端,比如11表示允许第一种和第二种类型的终端接入;10表示只允许第一种类型终端接入。
当通过终端类型的索引指示时,可以为每种终端类型设置相应的索引,在PBCH中的预留比特承载允许接入的终端类型的索引。
当所述指示信息指示所述指示信息所述指示信息对应的时域和/或频域资源支持的至少一种终端处理能力时,也可以通过PBCH中预留的3比特,来指示支持的终端处理能力。
此时,所述指示信息指示的方式包含以下之一:
通过终端处理能力的bitmap指示;
通过终端处理能力的索引指示。
其中,当以bitmap的形式指示时,不同的比特指示是否支持不同的终端处理能力。
当通过终端处理能力的索引指示时,可以为每种终端类型设置相应的索引,在PBCH中的预留比特承载支持的终端处理能力的索引。
当所述指示信息指示所述指示信息对应的时域和/或频域资源允许接入的终端类型优先级时,也可以通过PBCH中预留的3比特,来指示允许接入的终端类型优先级。
实际应用时,由于比特有限无法指示出每种终端类型的优先级,可以指示一种终端类型,例如有2种终端类型的情况下,1比特可指示,有3种终端类型的情况下,2比特可以指示。因此通过最多2比特可以指示最多4种终端类型。被指示的终端类型,表示当前对应的时域和/或频域资源上被高优先级服务的终端类型。则其他类型的终端则为低优先级服务的类型。示例性地,假设NR light(RedCap)终端分了2种类型,加上普通终端(即eMBB/URLLC终端)共有3种类型,有三种终端类型,假设分别是A、B、C,通过指示2比特,00对应类型A,01对应类型B,10对应类型C。假设当前指示的为01,当终端类型为A或C的终端(比如对应NR light终端的两种类型)收到该指示信息后,获知当前BWP中自己所属的终端类型并不是优先服务的,终端可以选择继续在该BWP上服务,也可以选择重新搜索寻找对应高优先级的BWP。
当所述指示信息指示至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源(即最适合某种终端类型的时域和/或频域资源位置)时,也可以通过PBCH中预留的3比特,来指示每种终端类型作为高优先级的时域和/或频域资源。
此时,所述指示信息指示的方式包括以下方式之一:
通过时域和/或频域资源的bitmap指示;
通过时域和/或频域资源的索引指示。
其中,示例性地,以BWP为例,当前SSB所对应的CORESET#0为20MHz带宽,指示的颗粒度为20MHz带宽,当前的CORESET#0不是高优先级服务的不需要指示,因此在指示的时候不需要包括这个BWP,因此可以通过2比特的bitmap(当只有2种终端类型时,指示被高优先级服务的终端类型只需要1比特,则还有2比特),可以指示2个BWP,分别包括1个比CORESET#0的频率高的时域和/或频域资源(比如BWP)和比其频率低的1个时域和/或频域资源是否为所述终端的终端类型最高优先级的时域和/或频域资源。示例性地,对于上述例子,指示当前时域和/或频域资源为终端类型B的最高优先级BWP,其他终端类型在该BWP均不是最高优先 级,即为低优先级,此时终端类型C和A的终端可以根据bitmap形式的指示,获知自身最高优先级服务的BWP。
当通过时域和/或频域资源的索引指示时,可以为每个时域和/或频域资源设置相应的索引,在PBCH中预留的比特(高位到低位或者低位到高位的顺序)承载每种终端类型对应的最高优先级服务的时域和/或频域资源的索引。这里,由于只有2比特,所以可以终端类型可以仅分为NR light终端和普通终端两种类型。
需要说明的是:实际应用时,当网络设备发送了多个SSB用于终端接入,此时有些SSB对应的CORESET#0(用于传输type0-PDCCH的CORESET资源)的带宽较小,不想让NR eMBB终端和/或URLLC终端接入,则可以在PBCH中的所述指示信息中指示对应的CORESET#0资源及其后续的广播消息等是否适用于某种类型的终端或者是否允许某种类型的终端接入。
在一实施例中,所述接收信息和/或发送信息,可以包括以下至少之一:
所述终端接收系统信息;
所述终端进行随机接入流程中的信息传输;
所述终端进行上行或者下行业务信道的传输。
其中,实际应用时,随机接入流程可以分布四步流程和两步流程。其中,在四步流程中,包含Message1,Message2,Message3和Message4的传输;其中,Message1和Message3是上行传输,由终端向网络侧发送;Message2和Message4是下行传输,由终端接收信息。终端可以在确定的时域和/或频域资源上进行流程中的至少一个消息(message)的传输。在两步流程中,包含Message A和Message B;其中,Message A是上行传输,由终端向网络侧发送;Message B是下行传输,由终端接收信息。终端可以在确定的时域和/或频域资源上进行流程中的至少一个message的传输。
实际应用时,所述网络设备指示的时域和/或频域资源可以是多个,终端会选择指示的多个时域和/或频域资源中的一个或多个,或者其中的一个或多个时域和/或频域资源对应的时域和/或频域资源,例如指示的为DL时隙频域,对应出一个UL的时域和/或频域资源,用于终端进行信息发送和/或接收。
其中,实际应用时,所述指示信息指示的时域和/或频域资源可以是直接指示的上行时域和/或频域资源,也可以是直接指示的下行时域和/或频域资源。如果直接指示的是上行时域和/或频域资源,则所述终端可以在上行时域和/或频域资源上发起随机接入。如果直接指示的是下行时域和/或频域资源,其会对应一个相应的上行时域和/或频域资源,比如对于TDD的DL BWP会对应一个中心频点相同的UL BWP,对于FDD,每个DL的BWP也会对应一个异频的UL的BWP。终端会在指示的下行时域和/或频域资源对应的时频上行资源上进行随机接入。随机接入过程中的下行与上行传输分别在指示的下行时域和/或频域资源及上行时域和/或频域资源上进行。
这里,当直接指示的时域和/或频域资源为上行时域和/或频域资源时,通常也会指示出其对应的下行时域和/或频域资源,用于终端接收随机接入响应等下行信息。下行时域和/或频域资源可以由所述指示信息指示或者由其他信息指示。
对应地,本申请实施例还提供了一种信息传输方法,应用于终端,如图5所示,该方法包括:

所述指示信息指示至少一种终端类型中每种终端类型作为高优先级的时域和/或频域资源时,所述终端可以确定当前的时频域资源是否是最高优先级服务的时域和/或频域资源;如果不是,可以进一步确定自身类型对应的最高优先级服务的时域和/或频域资源,进而确定自身接入哪个时域和/或频域资源。
其中,所述确定自身接收信息和/或发送信息的时域和/或频域资源,可以理解为确定自身工作的时域和/或频域资源。
在一实施例中,所述终端可以以下方式之一接收所述指示信息:
通过由SI-RNTI进行CRC加扰的控制信道接收所述指示信息;

从上面的描述可以看出,通过本申请实施例的方案,对于终端(比如NR Light终端),能够检测到可以用于自身工作的时域和/或频域资源,或者进一步地匹配出自身处理能力对应的时域和/或频域资源。当有多个时域和/或频域资源时,可以通过随机的方式或者通过终端标识确定其后续使用的时域和/或频域资源,通过确定出的时域和/或频域资源,接收系统消息,发起随机接入流程等。
基于此,在一实施例中,所述指示信息指示M个时域和/或频域资源可用;根据选择策略从M个可用的时域和/或频域资源中确定用于自身接收信息和/或发送信息的时域和/或频域资源(即确定接收信息的时域和/或频域资源和/或发送信息的时域和/或频域资源);M为大于1的正整数。

这里,示例性地,通过随机的方式确定使用的时域和/或频域资源时,假设NR light终端通过接收指示信息发现有M个BWP可以使用,则生成1到M的随机数,根据随机数结果选择接入的BWP。
在一实施例中,所述基于终端标识从M个可用的时频域资源中确定用于自身接收信息和/或发送信息的时域和/或频域资源,包括:
将终端标识进行取模操作,得到操作结果;
根据操作结果从M个可用的时域和/或频域资源中确定用于自身接收信息和/或发送信息的时域和/或频域资源。
其中,示例性地,假设终端使用其标识进行取模操作,根据结果判断其使用的BWP。例如NR light终端的标识对M取模,得到模值;当模值为0时,所述终端分到第一个BWP;当模值为1时,所述终端分到第2个BWP;当模值为2时,所述终端分到第3个BWP。所述终端标识可以是国际移动用户识别码(IMSI)、国际移动设备识别码(IMEI)、移动用户号码(MSISDN)、用户永久标识(SUPI,SUbscription Permanent Identifier),当然,也可以是其他参数,只要是能够表征终端的标识即可,本申请实施例对此不作限定。
将不同的终端分到不同的时域和/或频域资源上,不同能力的终端可进一步细分BWP,避免终端都在SSB所在的initial BWP上进行初始接入和数据传输。
本申请实施例还提供了一种信息传输方法,如图6所示,该方法包括:
