Description

确定调制编码阶数表类型的方法及装置
本申请要求在2018年08月10日提交中国专利局、申请号为201810911013.2的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,例如涉及一种确定调制编码阶数表类型的方法及装置。
背景技术
在通信系统中,用户设备(User Equipment,UE)会在连续接收(non-Discontinuous Reception,non-DRX)模式子帧上根据所要监听的下行控制信息格式(Downlink Control Information format,DCI format)来尝试解码搜索空间(Search Space,SS)中的每个候选物理下行控制信道(Physical Downlink Control Channel,PDCCH)。UE的搜索空间有公共搜索空间(Common Search Space,CSS)和UE特定搜索空间(UE-specific Search Space,USS)。公共搜索空间的起始位置为控制信道元素CCE0(Control Channel Element,CCE),UE特定搜索空间的起始位置可以通过公式计算得到。在新无线接入技术(New Radio Access Technology,NR)中,UE只会在聚合等级(Aggregation Level,AL)L∈{4,8,16}上监听公共搜索空间,但会在聚合等级L∈{1,2,4,8,16}上监听UE特定搜索空间,公共搜索空间和UE特定搜索空间可能重叠。在CSS和USS重叠的情况下,若当前所需监听的DCI format在CSS和USS上均可传输,例如,NR中的DCI format 0_0/1_0,则UE在监听到PDCCH携带的这种DCI format时,可能无法判断当前所需监听的DCI format所处的搜索空间类型。
在新无线接入技术超可靠低时延通信(Ultra-Reliable and Low Latency Communications,URLLC)的授权(Grant-Based,GB)传输中,64正交振幅调制(Quadrature Amplitude Modulation,QAM)调制编码阶数(Modulation and Coding Scheme,MCS)表格分为A类型和B类型两种,其中,两个表格中的大部分条目对应的码率和频谱效率(Spectrum Efficiency,SE)是相同的,但A类型表格可支持更低的码率和SE,B类型表格可支持更高的码率和SE。在无线接 入网络(Radio Access Network,RAN)1#93次会议通过的提议中规定,当无线资源控制(Radio Resource Control,RRC)未配置某种特定的无线网络临时识别符(Radio Network Temporary Identify,RNTI)且用于指示MCS表格使用类型的RRC参数指示A类型表格时,需要根据DCI format 0_0/1_0/0_1/1_1所处的搜索空间类型确定使用哪一种类型的MCS表格。相关技术中,NR中的DCI format 0_1/1_1只在UE特定搜索空间传输,而DCI format 0_0/1_0可在CSS和USS两种搜索空间中传输。因此,UE可能会因CSS和USS重叠而无法确定DCI format 0_0/1_0所处的搜索空间类型,并最终无法确定使用的64QAM MCS表格(table)的类型。
针对上述问题,相关技术中尚未存在解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。
首先,对本申请的背景进行介绍:
相关技术中,定义在聚合等级L∈{1,2,4,8,16}上的搜索空间SS为PDCCH候选集。UE会在子帧上根据所要监听的DCI format来尝试解码UE的搜索空间SS中的每个候选PDCCH。搜索空间分为公共搜索空间CSS和UE特定搜索空间USS。公共空间用于传输小区级的公共信息,多为控制信息,例如NR中,DCI format 0_0/1_0中包含的是用于保证基础工作的信息,该信息对于所有的UE来说都是一样的。UE特定搜索空间用于传输与上传共享信道(Up Load-Shared Channel,UL-SCH)、下载共享信道(Down Load-Shared Channel,DL-SCH)等相关的控制信息(UE级的信息),只有特定的UE才能够译码得到具体的信息内容。CSS用于传输公共控制信息,要求可靠度更高,使用更高聚合等级以提供更多的保护。而USS用于传输UE特定的数据,聚合等级种类较多。1个PDCCH在n个连续的CCE上传输,每个CCE由多个资源单元组(Resource Element Group,REG)组成。
在NR中,UE监听的公共搜索空间有Type0-PDCCH、Type0A-PDCCH、Type1-PDCCH和Type2-PDCCH四种,其中,Type0-PDCCH、Type0A-PDCCH和Type2-PDCCH的公共搜索空间的控制资源集(Control Resource Set,CORESET)是相同的,Type0-PDCCH、Type0A-PDCCH和Type2-PDCCH的CCE聚合等级和PDCCH候选集个数
Figure PCTCN2019100059-appb-000001
均一一对应,如表1所示。在每个服务小区(Serving Cell,SC)中,高层信令会给UE配置Q个CORESETs,其中,第q个CORESET用CORESET q表示,0≤q≤Q-1。每个CORESET中配置了正交频 分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,资源块(Resource Blocks,RBs)集合,CCE-to-REG映射信息和天线端口等时频域资源,每个CORESET包含一组从0到NCCE q-1编号的CCEs,其中NCCE q是CORESET q中的CCEs的个数。对于non-DRX模式,UE根据高层参数配置的符号周期,监听CORESET q中的候选PDCCH。每个服务小区和时隙的最大非重叠CCE的个数

和最大候选PDCCH的个数

都与子载波间隔一一对应,如表2和3所示,UE特定搜索空间的最大PDCCH候选集个数为

其中,公共搜索空间的CCE聚合等级L∈{4,8,16},UE特定搜索空间的CCE聚合等级L∈{1,2,4,8,16},公共搜索空间的起始位置从CCE0开始,UE特定搜索空间的起始位置由公式计算得到。公共搜索空间和UE特定搜索空间可能重叠。

NR中,对于一个服务小区的下行带宽部分(Bandwidth Part,BWP),当配置一个UE在搜索空间中监听PDCCH时,高层参数会给UE配置一个搜索空间集索引s和控制资源集索引p。对于CORESETp中的搜索空间集s,由高层参数指示给UE此搜索空间集s的搜索空间类型(CSS/USS),若搜索空间集s的搜索空间类型为公共搜索空间,则UE监听PDCCH携带的由一种或多种RNTI加扰的DCI format 0_0和DCI format 1_0,以及DCI format 2_0,DCI format 2_1,DCI format 2_2,and DCI format 2_3;若搜索空间集s的搜索空间类型为UE特定搜索空间,则UE监听PDCCH携带的DCI format 0_0,DCI format 1_0,DCI format 0_1和DCI format 1_1。即DCI format 0_0和DCI format 1_0既可在CSS上传输,又可在USS上传输。
综上所述,在CSS和USS重叠的情况下,若UE在CSS和USS重叠区域监听到PDCCH携带DCI format 0_0/1_0,UE无法判断自身所处的搜索空间类型。
NR中CSS和USS重叠问题描述:
RAN1#93会议中对URLLC的MCS table使用方法做出以下结论:对于URLLC,基于grant-based传输中,指定RNTI由RRC参数配置。
如果RRC没有配置指定RNTI,则原有RRC参数MCS-table指示的MCS table可以扩展到3种,即A类型表,B类型表,C类型表。
如果MCS-table指示A类型表,则按照如下规则使用MCS table:对于处于CSS的DCI format 0_0/1_0/0_1/1_1,使用B类型表;对于处于USS的DCI format  0_0/1_0/0_1/1_1,使用A类型表。
如果MCS-table指示的不是A类型表,按照原有操作进行。
在本实施例中,下行链路(DownLink,DL)和上行链路(UpLink,UL)是分开配置的。
如果RRC配置了指定RNTI,则利用加扰下行控制信息循环冗余校验(Downlink Control Information Cyclic Redundancy Check,DCI CRC)的RNTI来选择要使用的MCS table:如果DCI CRC由指定RNTI加扰,则使用A类型表;如果DCI CRC未由指定RNTI加扰,按照原有操作进行。
由于NR中CSS与USS可能存在重叠,并且导致承载DCI的PDCCH候选集同时属于CSS和USS的情况,此时UE无法区分PDCCH携带的DCI format 0_0/1_0是处于CSS还是USS,即采用DCI format 0_0/1_0是否处于CSS或USS的方式来区分使用A类型表或B类型表是不合理的,如图1虚线框部分,图1是相关技术中URLLC grant-based传输时,MCS table的部分选取规则示意图。总结上述URLLC中确定使用MCS table类型的流程,当RRC未配置指定RNTI且RRC参数MCS-table指示A类型表时,通过CSS和USS区分使用B类型表还是A类型表可能会导致协议模糊。
综上所述,相关技术中导致协议模糊的原因有三个方面:1)CSS和USS可能重叠;2)DCI format 0_0/1_0既可在CSS中传输又可在USS中传输;3)CSS和USS重叠时,没有已有的操作去指示UE监听到的信息所处的搜索空间类型。

本可选实施方式1-8提供了方案以解决相关技术中CSS和USS重叠的问题,以及CSS和USS重叠导致UE无法区分搜索空间类型的问题,以达到UE可以明确使用A类型的调制编码阶数表或B类型的调制编码阶数表的目的。其中,采用预定义,RRC配置和重新建立MCS索引映射关系等方法使得UE在CSS和USS重叠时,明确MCS table类型;采用其他参数区分UE使用的MCS table类型,避免CSS和USS重叠问题对UE的影响;采用传输避免和配置多个CORESET的方法,解决CSS和USS重叠问题,达到UE可以明确搜索空间类型的目的。下面结合可选实施方式1-8对上述方式进行描述。
可选实施方式1
本可选实施方式提供了一种解决CSS和USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的增强移动宽带(enhanced Mobile Broadband,eMBB)场景、超可靠低时延通信URLLC 场景或者大规模物联网场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,在RRC参数未配置指定RNTI且MCS-table指示A类型MCS table的情况下,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示,C类型表如附录中的表7所示。
本可选实施方式采用预定义方法,定义在CSS和USS重叠时,UE按照固定一类型的搜索空间选择要使用的MCS table;或由RRC参数配置当前PDCCH传输的搜索空间类型,以协助UE区分MCS table的使用,定义由RRC参数search-space-type指示UE一个搜索空间类型。操作流程如下方案所述。
预定义方法:
方案一,在下行控制信息格式DCI format为0_0/0_1,UE未被配置指定无线网络临时识别符RNTI,且用于指示调制编码阶数表的类型的参数配置为A类型表,上行物理共享信道PUSCH由C-RNTI或SP-CSI-RNTI调度的情况下,若分配上行物理共享信道PUSCH的上行物理控制信道PUCCH处于UE特定搜索空间USS,UE确定调制编码阶数表的类型为A类型表;若分配上行物理共享信道PUSCH的上行物理控制信道PUCCH处于公共搜索空间CSS,UE确定调制编码阶数表的类型为B类型表;若USS和CSS两个搜索空间出现交叠,且所述UE无法确定搜索空间类型,则所述UE预定义搜索空间为公共搜索空间CSS,并确定调制编码阶数表的类型为B类型表。
在下行控制信息格式DCI format为1_0/1_1,UE未被配置指定RNTI,且配置调制编码阶数表的类型为A类型表,下行物理共享信道PDSCH由C-RNTI调度的情况下,若分配下行物理共享信道PDSCH的下行物理控制信道PDCCH处于UE特定搜索空间USS,UE确定调制编码阶数表的类型为A类型表;若分配下行物理共享信道PDSCH的下行物理控制信道PDCCH处于公共搜索空间CSS,UE确定调制编码阶数表的类型为B类型表;若USS和CSS两个搜索空间出现交叠,且UE无法确定搜索空间类型,则UE预定义搜索空间为公共搜索 空间CSS,并确定调制编码阶数表的类型为B类型表。
该方案利用DCI format 0_0/1_0承载用于回退(fall-back)传输的特点,在UE监听到DCI format 0_0/1_0/0_1/1_1时,使用B类型MCS table。
方案二,在下行控制信息格式DCI format为0_0/0_1,UE未被配置指定无线网络临时识别符RNTI,且配置调制编码阶数表的类型为A类型表,上行物理共享信道PUSCH由C-RNTI或SP-CSI-RNTI调度的情况下,若分配上行物理共享信道PUSCH的上行物理控制信道PUCCH处于UE特定搜索空间USS,UE确定调制编码阶数表的类型为A类型表;若分配上行物理共享信道PUSCH的上行物理控制信道PUCCH处于公共搜索空间CSS,UE确定调制编码阶数表的类型为B类型表;若USS和CSS两个搜索空间出现交叠,且所述UE无法确定搜索空间类型,则所述UE预定义搜索空间为UE特定搜索空间USS,并确定调制编码阶数表的类型为A类型表。
在下行控制信息格式DCI format为1_0/1_1,UE未被配置指定RNTI,且配置调制编码阶数表的类型为A类型表,下行物理共享信道PDSCH由C-RNTI调度的情况下,若分配下行物理共享信道PDSCH的下行物理控制信道PDCCH处于UE特定搜索空间USS,UE确定调制编码阶数表的类型为A类型表;若分配下行物理共享信道PDSCH的下行物理控制信道PDCCH处于公共搜索空间CSS,UE确定调制编码阶数表的类型为B类型表;若USS和CSS两个搜索空间出现交叠,且UE无法确定搜索空间类型,则UE预定义搜索空间为UE特定搜索空间USS,并确定调制编码阶数表的类型为A类型表。
该方案充分考虑了DCI format 0_0/1_0用于回退传输,为保证正常的基础工作,需要更高的可靠度这一特点。与B类型MCS table相比,A类型MCS table中支持的码率和SE更低,能达到的可靠性也更强。因此,当PDCCH携带DCI format 0_0/1_0/0_1/1_1时,UE使用A类型MCS table以保证更低的SE可以使用。
RRC参数配置方法:
方案一,在下行控制信息格式DCI format为0_0/0_1,UE未被指定RNTI,且配置调制编码阶数表的类型为A类型表,上行物理共享信道PUSCH由C-RNTI 或SP-CSI-RNTI调度的情况下,若分配上行物理共享信道PUSCH的上行物理控制信道PUCCH处于UE特定搜索空间USS,UE确定调制编码阶数表的类型为A类型表;若分配上行物理共享信道PUSCH的上行物理控制信道PUCCH处于公共搜索空间CSS,UE确定调制编码阶数表的类型为B类型表;若USS和CSS两个搜索空间出现交叠,且UE无法确定搜索空间类型,则UE根据RRC的参数指示搜索空间为USS,并确定调制编码阶数表的类型为A类型表;或UE根据RRC的参数指示搜索空间为CSS,并确定调制编码阶数表的类型为B类型表。
在下行控制信息格式DCI format为1_0/1_1,UE未被配置指定RNTI,且配置调制编码阶数表的类型为A类型表,下行物理共享信道PDSCH由C-RNTI调度的情况下;若分配下行物理共享信道PDSCH的下行物理控制信道PDCCH处于UE特定搜索空间USS,UE确定调制编码阶数表的类型为A类型表;若分配下行物理共享信道PDSCH的下行物理控制信道PDCCH处于公共搜索空间CSS,UE确定调制编码阶数表的类型为B类型表;若USS和CSS两个搜索空间出现交叠,且UE无法确定搜索空间类型,则UE根据RRC的参数指示搜索空间为USS,并确定调制编码阶数表的类型为A类型表;或UE根据RRC的参数指示搜索空间为CSS,并确定调制编码阶数表的类型为B类型表。
该方案在原有结论的流程上,增加对于USS和CSS搜索空间重叠时,使用RRC参数配置搜索空间类型,以协助UE明确要使用的MCS table。
方案二,在下行控制信息格式DCI format为0_0/0_1/1_0/1_1,UE未被配置指定RNTI,且配置调制编码阶数表的类型为A类型表的情况下,则当RRC参数search-space-type指示USS时,UE使用A类型MCS table;当RRC参数search-space-type指示CSS时,UE使用B类型MCS table。
该方案对原有流程进行了简化,即直接利用RRC参数配置搜索空间类型,其中对于DCI format 0_1/1_1,RRC参数只能配置为UE特定搜索空间类型;对于DCI format 0_0/1_0,RRC参数可配置CSS和USS两种搜索空间类型中的任意一种。
可选实施方式2
本可选实施方式提供了一种解决CSS和USS重叠时UE无法判断监听到的 PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,在RRC参数未配置指定RNTI且MCS-table指示A类型MCS table的情况下,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示。
本可选实施方式采用A/B类型MCS table融合的方法,定义在CSS和USS重叠时,UE使用融合了A类型MCS table和B类型MCS table中部分索引的hybrid MCS table,亦即DCI format中配置的MCS索引(0~31)分别对应到A类型MCS table和B类型MCS table,若配置的MCS索引处于x索引集合中,则UE使用B类型MCS table,若配置的MCS索引对应到剩余MCS索引中,则UE使用A类型MCS table。
在一实施例中,上述操作流程如下所述:
方案一,对于URLLC中grant-based传输,在RRC未配置指定RNTI且mcs-table指示A类型MCS table,对于DCI format 0_0/1_0/0_1/1_1,CSS和USS重叠的情况下,如果配置的MCS索引在0和x之间,则UE使用A类型MCS table中对应的码率和SE;如果配置的MCS索引在x+1~31之间,则UE使用B类型MCS table。或者在原有的结论上增加以下说明:对于DCI format0_0/1_0/0_1/1_1,在CSS和USS重叠的情况下,UE按照配置的MCS索引0~x对应使用A类型MCS table和MCS索引x+1~31对应使用B类型MCS table的映射关系执行。
按照该方案执行时,即可以保证A类型MCS table中较小的调制编码阶数索引(MCS Index)I MCS对应的较低码率和SE可以使用,又保证了B类型MCS table中较大I MCS对应的较高码率和SE可以使用。以URLLC中采用循环前缀-正交频分复用(Cyclic Prefix-Orthogonal Frequency Division Multiplexing,CP-OFDM)的A类型MCS table和TS38.214中用于PDSCH的MCS table1为例,取x=5,则按照上述映射关系得到融合的MCS table,如表4所示,MCS索 引为0~5时对应A类型MCS table的I MCS,MCS索引为6~28时对应B类型MCS table的I MCS,最后A类型MCS table和B类型MCS table的I MCS29~31一致,都是预留的。融合后的hybrid 64QAM MCS table既保留了A类型MCS table中的较低SE部分,又保留了B类型MCS table中的高SE部分,使得CSS和USS重叠时,UE既可达到较高的可靠性,又可支持高码率传输。
表4:CSS和USS重叠时,为保证最低SE可使用的hybrid MCS table。

方案二,对于URLLC中grant-based传输,在RRC未配置指定RNTI且mcs-table指示A类型MCS table,对于DCI format 0_0/1_0/0_1/1_1,CSS和USS重叠的情况下,如果配置的MCS索引在集合S A中,则UE使用A类型MCS table中对应的码率和SE;如果配置的MCS索引在S B中,则UE使用B类型MCS table。或者在原有MCS table确定流程中增加以下说明:对于DCI format 0_0/1_0/0_1/1_1,在CSS和USS重叠的情况,UE按照配置的MCS索引S A对应使用A类型MCS table和MCS索引S B对应使用B类型MCS table的映射关系执行。
按照该方案执行时,即可以保证A类型MCS table中较小I MCS对应的最低码率和SE可以使用,又保证了B类型MCS table中较大I MCS对应的最高码率和SE可以使用。以URLLC中采用CP-OFDM的A类型MCS table和TS38.214中用于PDSCH的MCS table1为例,取S A为包含0~31中的偶数索引{0,2,4,8,...,30},S B为包含0~31中的奇数索引{1,3,5,7,...,31},则按照上述映射关系得到融合的MCS table,如表5所示,MCS索引为偶数时对应A类型MCS table的I MCS,MCS索引为奇数时对应B类型MCS table的IMCS。融合后的hybrid MCS table既保留了A类型MCS table中的最低码率和SE,又保留了B类型MCS table中的最高码率和SE,且A类型MCS table和B类型MCS table中的MCS索引各占50%,保证几乎所有的区间内的码率和SE都能取到,使得CSS和USS重叠时,UE既可达到较高的可靠性,又可支持高码率传输。

可选实施方式3
本可选实施方式提供了一种解决CSS和USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,在RRC参数未配置指定RNTI且MCS-table指示A类型MCS table的情况下,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示。
本实施例利用不同类型DCI format来区分MCS table的使用,定义在DCI format的类型为一种DCI format的情况下,UE使用B类型MCS table,在其他类型的DCI format时,UE使用A类型MCS table。操作流程如下方案所述。
方案一,对于URLLC中grant-based传输,若RRC未配置指定RNTI且mcs-table指示A类型MCS table,则对于DCI format 0_0/1_0,UE使用A类型MCS table中对应的码率和SE;对于DCI format 0_1/1_1,UE使用B类型MCS table。
该方案考虑了DCI format 0_0/1_0的负载(payload)较小,且大部分情况下用于回退传输,因此,对可靠性要求较高。这种情况下,使用可支持较低码率和SE的A类型MCS table可以达到更高的可靠性。而DCI format 0_1/1_1的payload较大,使用可支持较高码率的B类型MCS table较为合理。
方案二,对于URLLC中grant-based传输,若RRC未配置指定RNTI且mcs-table指示A类型MCS table,则对于DCI format 0_0/1_0,UE使用B类型MCS table中对应的码率和SE;对于DCI format 0_1/1_1,UE使用A类型MCS table。
该方案最大程度的保留了原有结论的分类原则,对于只在USS内进行监听的DCI format 0_1/1_1,UE依然使用A类型MCS table,提供更高的传输可靠度; 那么对于DCI format 0_0/1_0,UE使用B类型MCS table,可支持更高的码率和SE。
可选实施方式4
本可选实施方式提供了一种解决CSS和USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,在RRC参数未配置指定RNTI且MCS-table指示A类型MCS table的情况下,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示。
本可选实施方式利用不同类型聚合等级或PDCCH候选集索引来区分MCS table的使用,或者通过给CSS和USS配置不同的聚合等级以利用不同类型聚合等级来区分MCS table的使用,定义对于指定范围内的聚合等级或候选集索引时,UE使用B类型MCS table,对于其他的聚合等级或PDCCH候选集ID时,UE使用A类型MCS table。
其中,操作流程如下所述:
方案一,对于URLLC中grant-based传输,若RRC未配置指定RNTI且mcs-table指示A类型MCS table,则对于DCI format 0_0/0_1/1_0/1_1,当所处聚合等级L∈S A时,UE使用A类型MCS table,当所处聚合等级L∈S B时,UE使用B类型MCS table。或者在原有结论的基础上增加说明:对于DCI format0_0/1_0,当所处聚合等级L∈S A时,UE使用A类型MCS table;当所处聚合等级L∈S B时,UE使用B类型MCS table。其中,S A∪S B={1,2,4,8,16}。
该方案考虑到两个MCS table中A类型MCS table支持的码率更低,可达到更高的可靠性,而较高的CCE聚合等级往往是为了给信息提供更多的保护,因此,若S A取值为{16},S B取值为{1,2,4,8},则对于DCI format 0_0/0_1/1_0/1_1,当UE监听到的DCI format 0_0/0_1/1_0/1_1信息所处CCE聚合等级为{16}时, 使用A类型MCS table;当UE监听到的DCI format 0_0/0_1/1_0/1_1信息所处CCE聚合等级为{1,2,4,8}时,使用B类型MCS table。
方案二,对于URLLC中grant-based传输,若RRC未配置指定RNTI且mcs-table指示A类型MCS table,则对于DCI format 0_0/0_1/1_0/1_1,当所处候选集索引k∈K A时,UE使用A类型MCS table,当所处候选集索引k∈K B时,UE使用B类型MCS table。或者在原有结论的基础上增加说明:对于DCI format 0_0/1_0,当所处候选集索引k∈K A时,UE使用A类型MCS table,当所处候选集索引k∈K B时,UE使用B类型MCS table。其中,
Figure PCTCN2019100059-appb-000014
该方案考虑到CCE聚合等级较小时,PDCCH候选集个数较多,且DCI format只会在一个候选PDCCH上传输,所以采用PDCCH候选集索引来区分MCS table的使用能使UE更加明确地执行后续的操作。例如,当CCE聚合等级为4时,有4个PDCCH候选集,若K A取值为{0,1},K B取值为{2,3},则对于DCI format 0_0/0_1/1_0/1_1,当监听到的DCI format 0_0/0_1/1_0/1_1所处候选PDCCH索引k∈K A时,UE使用A类型MCS table;当监听到的DCI format 0_0/0_1/1_0/1_1所处候选PDCCH索引k∈K B时,UE使用B类型MCS table。
方案三,对于URLLC中grant-based传输,若RRC未配置指定RNTI且mcs-table指示A类型MCS table,则对于DCI format 0_0/0_1/1_0/1_1,给CSS和USS配置不同的聚合等级,并按照方案一中利用不同的CCE聚合等级来区分当前所处的搜索空间类型,以确定使用的MCS table类型。
对于URLLC中grant-based传输,当RRC未配置指定RNTI且mcs-table指示A类型MCS table时,对于DCI format 0_0/0_1/1_0/1_1,采用CCE聚合等级和候选集索引来确定MCS table要比按照搜索空间类型的区分方法更加灵活。
可选实施方式5
根据本可选实施例的一个方面,本可选实施例提供的一种解决CSS和USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,若RRC 参数未配置指定RNTI且MCS-table指示A类型MCS table,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示。
本实施例利用不同类型的循环冗余校验掩码(Cyclic Redundancy Check mask,CRC mask)来区分MCS table的使用,定义当DCI format的CRC mask为一值时,UE使用B类型MCS table,当DCI format的CRC mask为另一值时,UE使用A类型MCS table。
其中,操作流程如下所述:
对于URLLC中grant-based传输,若RRC未配置指定RNTI且mcs-table指示A类型MCS table,则对于DCI format 0_0/1_0/0_1/1_1,当DCI format 0_0/1_0/0_1/1_1的CRC mask为X时,UE使用A类型MCS table,当DCI format 0_0/1_0/0_1/1_1的其CRC mask为Y时,UE使用B类型MCS table。或者在原有结论的基础上增加说明:对于DCI format 0_0/1_0,当其CRC mask为X时,UE使用A类型MCS table,当其CRC mask为Y时,UE使用B类型MCS table。其中,X和Y是单一的值或集合。
该方案考虑到UE每次监听到的DCI format的CRC mask值是唯一的,因此,利用DCI format 0_0/0_1/1_0/1_1的CRC mask来区分两种MCS table的使用,可以避免协议模糊的问题,使得UE明确使用的MCS table类型。
可选实施方式6
本可选实施方式提供了一种解决CSS和USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,若RRC参数未配置指定RNTI且MCS-table指示A类型MCS table,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A 类型MCS table如附录中的表8和表10所示。
本实施例采用指定RNTI来区分MCS table的使用。操作流程如下方案所述。
对于URLLC中grant-based传输,在RRC未配置指定RNTI,对于MCS-table指示A类型MCS table的情况下,UE使用B类型MCS table,在RRC未配置指定RNTI,对于MCS-table指示其他类型的MCS table的情况下,UE按照指示的表类型执行;在RRC配置指定RNTI的情况下,UE使用A类型MCS table。
该方案采用指定RNTI来区分A类型MCS table的使用,摒弃了原有结论中为RRC未配置指定RNTI还要使用A类型MCS table的冗余操作,减少UE所需判断的参数。
可选实施方式7
本可选实施方式提供了一种解决CSS和USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,若RRC参数未配置指定RNTI且MCS-table指示A类型MCS table,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示。
本可选实施方式采用划分DCI format信息传输区域的方法来区分MCS table的使用。
其中,操作流程如下所述:
对于URLLC中grant-based传输,若RRC未配置指定RNTI且MCS-table指示A类型MCS table,则对于DCI format 0_0/1_0,规定携带DCI format 0_0/1_0的PDCCH在CSS和USS非重叠区域传输。
该方案解决了RRC未配置指定RNTI且MCS-table指示A类型MCS table时,CSS和USS重叠导致UE可能无法区分DCI format 0_0/1_0所处搜索空间类 型的问题。通过本可选实施方式,无需对原有结论进行修改,并且使得UE可以明确判断出DCI format 0_0/1_0所处的搜索空间类型。
可选实施方式8
本可选实施方式提供了一种解决CSS/USS重叠时UE无法判断监听到的PDCCH所处的搜索空间类型的方法,可以应用于新无线接入技术NR中的eMBB场景、URLLC场景或者大规模物联网mMTC场景中。
CSS和USS重叠会导致UE无法区分监听到的PDCCH携带的DCI format 0_0/1_0所处的搜索空间类型,此时对于URLLC中的grant based传输,若RRC参数未配置指定RNTI且MCS-table指示A类型MCS table,则对于DCI format 0_0/1_0,UE无法区分自身所处搜索空间类型,进而无法确定使用A类型MCS table还是B类型MCS table。B类型MCS table如附录中的表6和表9所示,A类型MCS table如附录中的表8和表10所示。
本可选实施方式利用不同的CORESET配置以避免CSS和USS重叠现象发生,即给CSS和USS配置不同的CORESET,使得UE的CSS和USS无重叠。
其中,操作流程如下所述:
对于URLLC中grant-based传输,若RRC未配置指定RNTI且MCS-table指示A类型MCS table,则对于DCI format 0_0/1_0,给UE的CSS和USS配置不同的CORESET,以保证UE监听到的PDCCH不会处于CSS和USS的重叠区域。
在本可选实施方式考虑了资源充足的情况下,给CSS和USS配置不同的CORESET是可以保证CSS和USS不重叠的。一般来说,给CSS和USS配置不同的CORESET可以防止阻塞,提高可靠性。

实施例二
在本实施例中还提供了一种确定调制编码阶数表类型的装置,该装置设置为实现上述实施例,已经进行过说明的不再赘述。如以下所使用的,术语“模块”可以实现预定功能的软件和硬件中至少之一的组合。
