为便于更好的理解本申请实施例,对本申请相关的降低能力(Reduced Capbility,RedCap)终端进行说明。
NR系统主要是为了支持增强移动超宽带(Enhance Mobile Broadband,eMBB)业务而设计的。其主要技术是为了满足高速率、高频谱效率、大带宽的需要。实际上,除了eMBB业务,还存在多种不同的业务类型,例如传感器网络、视频监控、可穿戴等,它们在速率、带宽、功耗、成本等方面与eMBB业务有着不同的需求。支持这些业务的终端相比支持eMBB的终端的能力是降低的,如支持的带宽减小、处理时间放松、天线数减少等。需要针对这些业务和相应的低能力终端对NR系统进行优化,这样的系统称为轻量型NR(NR-light)系统。在LTE技术中,已经有了类似的系统设计用于支 持大连接数、低功耗、低成本的终端,如机器类通信(Machine Type Communication,MTC),窄带物联网(Narrow Band Internet of Things,NB-IoT)。在NR系统中,引入类似的技术用于使用NR技术更好的支持除eMBB业务之外的其他业务类型。支持这类业务的终端具有低复杂度、低成本、低能力的特点,称为RedCap终端。
为便于更好的理解本申请实施例,对本申请相关的物理广播信道(Physical Broadcast Channel,PBCH)进行说明。
PBCH信道承载的信息包括来自高层的A比特信息和层1相关的额外8比特信息,层1相关的信息包括系统帧号(System Frame Number,SFN)、半帧指示、同步信号块(Synchronization Signal Block,SSB)索引等。具体定义如下:
PBCH承载的比特包括来自高层的主信息块(Master Information Block,MIB),共A比特,

和来自层1的8比特,

其中A比特MIB的定义如下标准所描述,即包括SFN的6比特,子载波间隔信息1比特,SSB的子载波偏移4比特,解调参考信号(Demodulation Reference Signal,DMRS)相关信息、调度系统信息块(System Information Block,SIB)的物理下行控制信道(Physical Downlink Control Channel,PDCCH)的资源信息等,其中还包含了1个空闲比特。

中,

为SFN的最低4位;

为半帧指示;当L SSB=64时,
Figure PCTCN2020127157-appb-000006
为SSB索引的最高3位,否则,

Figure PCTCN2020127157-appb-000008
为保留比特。其中,L SSB为最大的SSB个数,k SSB为SSB的子载波偏移信息。当系统频带小于6GHz时,即L SSB小于64时,层1相关的信息有2比特保留比特。
在上述MIB信息中,小区受限(cellBarred)用于指示小区的接入控制状态,它和SIB1中的预留给操作使用的小区(cellReservedForOperatorUse)和预留给其他使用的小区(cellReservedForOtherUse)共同用于确定小区的接入控制状态。
cellBarred="非受限(not barred)",并且cellReservedForOperatorUse="非预留(not reserved)",并且cellReservedForOtherUse=不是(not)"真实(true)",小区状态(cell status)="not barred",UE可以将该小区作为小区选择或者重选的候选小区。
cellBarred="受限(barred)",或者cellReservedForOtherUse="true",cell status="barred"。
cellBarred="非受限(not barred)",并且cellReservedForOperatorUse="预留(reserved)",并且cellReservedForOtherUse=not"true",被指派为接入标识(Access Identity)11或15的终端(UE)可以将该小区作为小区选择或者重选的候选小区,被指派为Access Identity 1,2和12至14的终端(UE)认为该小区的状态为"受限(barred)"。
对于一个小区,可以为传统终端(UE)提供接入服务。在为降低能力终端(RedCap UE)提供服务时,有两种方式,一种方式是一个小区专门为RedCap UE服务,可以采用一个特定的小区为RedCapUE服务,此时对于RedCap UE的接入可以单独控制,可以沿用现有的控制方式;另一种方式是一个小区可以同时为传统UE和RedCap UE服务,即两种UE在网络中共存。这种方式下,对于传统UE和RedCap UE的接入控制需要分别进行控制,例如,只允许传统UE接入。但是,现阶段,小区状态(cell status)只用于一个小区对传统UE的接入控制,并不能分别对传统UE和RedCap UE分别进行接入控制,也即会对传统UE和RedCap UE的接入同等对待,无法分别进行控制。
需要说明的是,传统UE可以是非RedCap UE,或者eMBB UE,或者NR UE。本申请对此并不限定。
在一些通信场景中,网络设备可以在DCI中指示不同的控制信息,此情况下,终端设备无法识别DCI中的控制信息。
基于上述问题,本申请提出了一种确定DCI中所指示的控制信息的方案,终端设备可以准确识别DCI中的控制信息,从而可以正确接收DCI中的控制信息,提升通信性能。
以下通过具体实施例详述本申请的技术方案。
图2是根据本申请实施例的无线通信的方法200的示意性流程图,如图2所示,该方法200可以包括如下内容中的至少部分内容:
S210,网络设备向终端设备发送目标DCI;
S220,该终端设备接收该目标DCI;
S230,该终端设备根据以下中的至少一种确定该目标DCI中所指示的控制信息:
该目标DCI中的保留比特中的至少一个信息域;加扰该目标DCI的RNTI;承载该目标DCI的PDCCH所占用的时频资源。
也即,在本申请实施例中,该目标DCI中所指示的控制信息可以通过以下中的至少一种确定:
该目标DCI中的保留比特中的至少一个信息域;加扰该目标DCI的RNTI;承载该目标DCI的PDCCH所占用的时频资源。
在本申请实施例中,“保留比特”也可以称之为“预留比特”,本申请对此不作限定。
可选地,该目标DCI中可以指示一种或者多种类型的控制信息,以及指示每种类型下的一个或者多个控制信息。
例如,终端设备可以根据目标DCI中的保留比特中的至少一个信息域确定目标DCI中所指示的控制信息。通过在目标DCI中的保留比特中定义至少一个信息域,以区别版本15(Release15,Rel-15)或版本16(Release16,Rel-16)基站发送的DCI中保留比特的取值,可以避免终端设备不知道目标DCI中的保留比特的取值表示的含义而产生理解上的偏差,从而可以正确接收控制信息。
又例如,终端设备可以根据加扰目标DCI的无线网络临时标识符(Radio Network Temporary Identity,RNTI)确定目标DCI中所指示的控制信息。通过不同的加扰DCI的RNTI对应不同的DCI中所指示的控制信息,可以避免终端设备对于DCI中的比特含义的理解出现偏差,从而可以正确接收控制信息。
再例如,终端设备可以根据承载目标DCI的PDCCH所占用的时频资源确定目标DCI中所指示的控制信息。通过不同的承载DCI的PDCCH所占用的时频资源对应不同的DCI中所指示的控制信息,可以避免终端设备对于DCI中的比特含义的理解出现偏差,从而可以正确接收控制信息。
可选地,在本申请实施例中,该目标DCI中所指示的控制信息至少包括降低能力终端的控制信息。
可选地,该控制信息可以是接入控制信息。也即,该目标DCI中所指示的控制信息至少可以包括降低能力终端的接入控制信息。
当然,本申请实施例中的控制信息也可以是其他的控制信息,本申请对此并不限定。
可选地,该目标DCI的格式为DCI格式1_0(DCI format 1_0)。
需要说明的是,DCI format 1_0中包括了承载SIB1的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的调度信息,包括频域和时域资源分配、调制编码方案等。由于DCI format 1_0作为公共搜索空间的PDCCH承载的DCI,其只包含基本的功能域,域大小尽可能固定,少依赖无线资源控制(Radio Resource Control,RRC)配置。为了减少DCI大小的种类,不同的DCI format可能采用相同的大小,这就需要DCI中存在一些保留比特。对于DCI format 1_0来说,对于授权频谱的情况,如循环冗余码校验(Cyclical Redundancy Check,CRC)用系统信息RNTI(System Information RNTI,SI-RNTI)加扰的DCI format 1_0来说,除了有用控制信息比特之外,还包含了15个比特作为保留比特未被使用。
由于保留比特的取值在标准中并未规定,在网络设备的实现中,该保留比特的取值不做规定,不同的厂商可能将保留比特设置成不同的值,例如全零。这就存在一个问题,当RedCap UE接收到Rel-15或Rel-16的基站发送的DCI时,由于RedCap UE不知道基站的版本,也不知道该DCI中的保留比特的取值表示的含义,例如Rel-15或Rel-16的基站将保留比特设置成1,而在版本17(Release17,Rel-17)标准中,该保留比特被定义成指示RedCap UE的控制接入信息,取值为1表示允许RedCap UE接入该小区,当RedCap UE收到Rel-15或Rel-16的基站中该保留比特时,会误认为该小区支持RedCap UE的接入,而去继续接收SIB消息,造成RedCap UE尝试接入的失败,带来额外的耗电。
可选地,作为示例1,该终端设备根据该目标DCI中的保留比特中的至少一个信息域确定该目标DCI中所指示的控制信息。
可选地,在示例1的实现方式1中,该至少一个信息域包括标识比特域和控制信息域,也即,该目标DCI中的保留比特中包括标识比特域和控制信息域,如图3所示。
其中,该控制信息域用于指示至少一个控制信息,该标识比特域用于指示该控制信息域中所指示的控制信息的类型。或者,该标识比特域用于指示该控制信息域的含义。
也即,标识比特域中的比特的不同取值可以指示控制信息域中指示的是不同类型的控制信息。
可选地,在实现方式1中,该标识比特域用于指示控制信息域中的比特用于指示RedCap UE接入控制信息。
因此,通过在目标DCI中的保留比特中定义标识比特域,以区别Rel-15或Rel-16的基站发送的DCI中保留值的取值,避免RedCap UE不知道该目标DCI中的保留比特的取值表示的含义而产生的混淆,从而可以正确接收针对RedCap UE的接入控制信息,避免了RedCap UE盲目的尝试接入,造成额外的耗电。
可选地,在实现方式1中,该标识比特域的取值不包括全0或全1。从而可以避免与Rel-15或Rel-16的基站中保留比特的取值相同而发生混淆。
可选地,在实现方式1中,该标识比特域占用多个比特,且该标识比特域占用的比特数大于第一阈值。该第一阈值可以是预配置或者协议约定的,或者,该第一阈值为网络设备配置的。
可选地,该标识比特域占用的比特数也可以是一个固定值,该固定值可以是协议约定的。
需要说明的是,标识比特域包含的比特数越多,与Rel-15或Rel-16的基站中保留比特的取值相同而发生混淆的可能性越低。
可选地,在实现方式1中,该标识比特域的取值所指示的含义为预配置或者协议约定的,或者,该标识比特域的取值所指示的含义为网络设备配置的。
例如,可以预配置如下信息:标识比特域中的比特取值00指示控制信息类型1,标识比特域中的比特取值01指示控制信息类型2,标识比特域中的比特取值10指示控制信息类型3,标识比特域中的比特取值11指示控制信息类型4。
在实现方式1中,假设标识比特域包含5比特,控制信息与包含2比特,标识比特域对应的控制信息域的含义例如可以如下表1所示。
表1
标识比特域(5比特) 控制信息类型 控制信息域(如2比特)
10101 控制信息类型1 控制信息1-4
01010 控制信息类型2 控制信息1-4
11100 控制信息类型3 控制信息1-4
00011 控制信息类型4 控制信息1-4
…… …… ……
可选地,在示例1的实现方式2中,该至少一个信息域包括控制信息域,也即,该目标DCI中的保留比特中包括控制信息域,如图4所示。
其中,该控制信息域用于指示第一控制信息类型的至少一个控制信息。
可选地,在实现方式2中,该控制信息域中的比特用于指示RedCap UE接入控制信息。
可选地,控制信息域包含多个比特,例如定义保留比特中的3个比特作为控制信息域,当控制信息域中的比特取值为“010”时,表示指示允许RedCap UE接入小区;当控制信息域中的比特取值为“011”时,表示指示拒绝RedCap UE接入小区。由于控制信息域的特定的取值与Rel-15或Rel-16的基站中保留比特的取值相同的可能性较低,因此可以使得RedCap UE可以确定收到的目标DCI中的控制信息域承载的是RedCap UE的接入控制信息。
因此,通过在目标DCI中的保留比特中定义控制信息域,以区别Rel-15或Rel-16的基站发送的DCI中保留值的取值,避免RedCap UE不知道该目标DCI中的保留比特的取值表示的含义而产生的混淆,从而可以正确接收针对RedCap UE的接入控制信息,避免了RedCap UE盲目的尝试接入,造成额外的耗电。
可选地,在实现方式2中,该控制信息域的取值不包括全0或全1。从而可以避免与Rel-15或Rel-16的基站中保留比特的取值相同而发生混淆。
可选地,在实现方式2中,该控制信息域占用多个比特,且该控制信息域占用的比特数大于第二阈值。该第二阈值可以是预配置或者协议约定的,或者,该第二阈值为网络设备配置的。
可选地,该控制信息域占用的比特数也可以是一个固定值,该固定值可以协议约定的。
需要说明的是,控制信息域包含的比特数越多,与Rel-15或Rel-16的基站中保留比特的取值相同而发生混淆的可能性越低。
可选地,在实现方式2中,该控制信息域的取值所指示的含义为预配置或者协议约定的,或者,该控制信息域的取值所指示的含义为网络设备配置的。例如,可以预配置如下信息:控制信息域中的比特取值00指示控制信息1,控制信息域中的比特取值01指示控制信息2,控制信息域中的比特取值10指示控制信息3,控制信息域中的比特取值11指示控制信息4。
在实现方式2中,假设控制信息域包含5比特,控制信息域的含义例如可以如下表2所示。
表2
控制信息域(5比特) 控制信息
10101 控制信息1
01010 控制信息2
11100 控制信息3
00011 控制信息4
…… ……
可选地,作为示例2,该终端设备根据加扰该目标DCI的RNTI确定该目标DCI中所指示的控制信息。也即,不同的加扰DCI的RNTI对应不同的DCI中所指示的控制信息。
可选地,该目标DCI为DCI format 1_0。
可选地,该控制信息可以是接入控制信息。
可选地,在示例2中,降低能力终端(RedCap UE)的控制信息通过降低能力终端对应的RNTI加扰的所述目标DCI指示。例如,降低能力终端对应的RNTI为SI-RNTI-R。也即SI-RNTI-R专门用于RedCap UE接收DCI format 1_0。
也就是说,为了避免传统UE和RedCap UE在共用SI-RNTI加扰的DCI format 1_0时对于其中的控制信息的含义的混淆问题,对于RedCap UE,可以通过定义新的RNTI来加扰DCI format 1_0的CRC。也即,RedCap UE的控制信息通过RedCap UE对应的SI-RNTI-R加扰的DCI format 1_0指示。
可选地,降低能力终端对应的SI-RNTI-R加扰的DCI format 1_0与SI-RNTI加扰的DCI format 1_0中可以具有相同的控制信息,例如包括:
频域资源分配信息,时域资源分配信息,调制编码方案,冗余版本,虚拟资源块到物理资源块的映射方式,系统消息指示。
可选地,SI-RNTI-R加扰的DCI format 1_0与SI-RNTI加扰的DCI format 1_0中SIB的调度信息是相同的,即它们指示相同的PDSCH的调度信息。在此基础上可以用DCI中的剩余比特定义指示RedCap UE的接入控制信息,此时由于RNTI的不同,RedCap UE不会与传统DCI format 1_0中的比特的含义产生混淆。具体可以如图5所示。
可选地,承载用SI-RNTI-R加扰的DCI format 1_0的PDCCH的搜索空间与承载用SI-RNTI加扰的DCI format 1_0的PDCCH的搜索空间相同,都是通过主信息块(Master Information Block,MIB)进行指示。
具体的,用SI-RNTI-R加扰的DCI的格式(format)也可以不是DCI format 1_0,用SI-RNTI-R加扰的DCI的format可以不包含SIB的调度信息,RedCap UE还是通过SI-RNTI加扰的DCI format 1_0获得SIB的调度信息。
因此,通过不同RNTI加扰的DCI,可以避免RedCap UE对于DCI中的比特含义的模糊,可以正确接收针对RedCap UE的接入控制信息,避免了RedCap UE盲目的尝试接入,造成额外的耗电。
可选地,作为示例3,该终端设备根据承载该目标DCI的PDCCH所占用的时频资源确定该目标DCI中所指示的控制信息。也即,不同的承载DCI的PDCCH所占用的时频资源对应不同的DCI中所指示的控制信息。
可选地,该目标DCI为DCI format 1_0。承载DCI format 1_0的PDCCH可以是类型0的PDCCH(type0-PDCCH)。也即,承载该目标DCI的PDCCH可以是type0-PDCCH。
可选地,该控制信息可以是接入控制信息。
可选地,降低能力终端(RedCap UE)的控制信息通过基于降低能力终端对应的PDCCH的控制资源集合(Control Resource Set,CORESET)和/或搜索空间(Search Space)接收的该目标DCI指示。
在示例3的一种实现方式中,针对RedCap UE的type0-PDCCH(承载目标DCI)与针对传统UE的type0-PDCCH(承载目标DCI)可以在不同的频域带宽上发送。因此不存在DCI共用而产生的对其中的比特含义的混淆问题,可以在针对RedCap UE的type0-PDCCH中承载的DCI中指示RedCap UE的接入控制信息。如图6所示,RedCap UE的type0-PDCCH和传统UE的type0-PDCCH在不同的带宽部分(Band Width Part,BWP)上发送。
在示例3的另一种实现方式中,如果针对RedCap UE的type0-PDCCH(承载目标DCI)和针对传统UE的type0-PDCCH(承载目标DCI)在相同的频域资源上发送,即它们对应的CORESET 0相同,还可以规定它们的监听时机不同,即Search Space 0不同,使得针对RedCap UE的type0-PDCCH和针对传统UE的type0-PDCCH在不同的时域资源上发送,因此不存在DCI共用而产生的对其中的比特含义的混淆问题,可以在针对RedCap UE的type0-PDCCH中承载的DCI中指示RedCap UE的接入控制信息。如图7所示,RedCap UE的type0-PDCCH和传统UE的type0-PDCCH具有不同的监听时机。
具体的,RedCap UE通过MIB获得SIB1信息后,得到CORESET 0和Search Space 0,根据关联关系,确定针对RedCap UE的CORESET和SearchSpace中的至少一个,可以称为CORESET 0-R和Search Space 0-R。关联关系可以通过预配置或者协议约定规则确定。由于RedCap UE和传统UE的type0-PDCCH的CORESET和Search Space中的至少一个是不同的,因此不存在DCI共用而产生的对其中的比特含义的混淆问题,可以在针对RedCap UE的type0-PDCCH中承载的DCI中指示RedCap UE的接入控制信息。
因此,通过针对传统UE和RedCap UE的PDCCH的不同的时域或频域资源,可以避免RedCap UE对于DCI中的比特含义的模糊,可以正确接收针对RedCap UE的接入控制信息,避免了RedCap UE盲目的尝试接入,造成额外的耗电。
需要说明的是,在本申请实施例中,传统UE可以是非RedCap UE,或者eMBB UE,或者NR UE。本申请对此并不限定。
因此,在本申请实施例中,终端设备可以根据目标DCI中的保留比特中的至少一个信息域、加扰目标DCI的RNTI、承载目标DCI的PDCCH所占用的时频资源中的至少一种确定目标DCI中所指示的控制信息,从而可以正确接收DCI中的控制信息,提升通信性能。
例如,终端设备可以根据目标DCI中的保留比特中的至少一个信息域确定目标DCI中所指示的控制信息。通过在目标DCI中的保留比特中定义至少一个信息域,以区别Rel-15或Rel-16基站发送的DCI中保留比特的取值,可以避免终端设备不知道目标DCI中的保留比特的取值表示的含义而产生理解上的偏差,从而可以正确接收控制信息。
又例如,终端设备可以根据加扰目标DCI的RNTI确定目标DCI中所指示的控制信息。通过不同的加扰DCI的RNTI对应不同的DCI中所指示的控制信息,可以避免终端设备对于DCI中的比特含义的理解出现偏差,从而可以正确接收控制信息。
再例如,终端设备可以根据承载目标DCI的PDCCH所占用的时频资源确定目标DCI中所指示的控制信息。通过不同的承载DCI的PDCCH所占用的时频资源对应不同的DCI中所指示的控制信息,可以避免终端设备对于DCI中的比特含义的理解出现偏差,从而可以正确接收控制信息。
