具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开进行详细描述。
下面先对本公开的相关技术进行简要的说明。
当同一个载波上两个CSI报告所使用的PUCCH资源在时域上至少有一个OFDM符号重叠,那么这两个CSI报告便发生碰撞。每个CSI报告对应一个优先级,发生CSI报告碰撞或上行传输资源有限的情况下UE则不发送优先级较低的一些CSI报告。例如:CSI优先级首先根据规则1确定优先级,如果按规则1得到的优先级相等,则根据规则2确定优先级,以此类推。
规则1:依据时域行为/信道类型(AP-CSI>SP-CSI on PUSCH>SP-CSI on PUCCH>P-CSI);
规则2~4仅适用于基于PUCCH传输的P-CSI和SP-CSI:
规则2:CSI内容(Beam reports>CSI);
规则3:cellID(PCell>PSCell>按升序排列的其他cell ID);
规则4:csiReportID(升序排列)。
CSI报告分为Type I和Type II:
1)Type I的CSI报告最多分成两部分:
Part 1包含秩指示(Rand Indicator,RI)/信道状态信息参考信号资源指示(Channel State Information Reference Signal Resource Indicator,CRI)、第一个码字的信道质量指示(Channel Quality Indicator,CQI);
Part 2包含预编码矩阵指示(Precoding Matrix Indicator,PMI)和当RI>4时的第二个码字的CQI。
2)Type II的CSI报告最多分成两部分:
Part 1具有固定的载荷长度用于指示Part 2的比特长度,包含RI、CQI和每层非零宽带幅度系数的数目;
Part 2则包含Type II的PMI。
除了Type I和Type II的CSI报告,还有用于波束管理的波束信息报告“CRI/RSRP(Reference Signal Received Power)”和“SSBRI/RSRP”等,此时的CSI报告仅有一个部分。
NR支持给用户设备(User Equipment,UE)在每个带宽部分(Band Width Part,BWP)上配置J>=1个第一CSI PUCCH资源(或称为多CSI PUCCH,multi-CSI PUCCH)用于承载多个基于PUCCH的CSI报告,该PUCCH资源的配置包含PUCCH Format 2/3/4以及最大的码率。当两个或多个基于PUCCH的CSI报告发生碰撞时,则UE在多CSI PUCCH上发送部分个数或全部个数高优先级的CSI报告,丢弃其他的CSI报告。可以发送的CSI报告数量可由为多CSI PUCCH配置的码率决定。
因此,网络侧可以配置一个或多个可以承载多个CSI报告的第一CSI PUCCH,发生碰撞多个基于PUCCH的CSI报告可以在该第一CSI PUCCH上传输而不是简单地丢弃。
本公开针对多个基于PUCCH的CSI报告发生碰撞时丢弃CSI报告造成网络侧获取CSI报告不及时或CSI报告缺失的问题,提供一种信道状态信息报告的传输方法及终端。
具体地,如图1所示,本公开实施例的一种信道状态信息报告的传输方法,应用于终端,包括:
步骤101,获取在物理上行链路控制信道PUCCH上传输的信道状态信息 CSI报告的分配规则,所述分配规则由网络设备配置或协议约定;
步骤102,在至少两个CSI报告存在碰撞时,根据所述分配规则,将部分个数或全部个数存在碰撞的CSI报告分配给第一CSI PUCCH;
步骤103,进行所述部分个数或全部个数存在碰撞的CSI报告的传输;
其中,第一CSI PUCCH用于传输部分个数或全部个数存在碰撞的CSI报告(即第一CSI PUCCH是指上述的多CSI PUCCH)。
本公开实施例提供的所述信道状态信息报告的传输方法通过获取在物理上行链路控制信道PUCCH上传输的信道状态信息CSI报告的分配规则,在至少两个CSI报告存在碰撞时,根据所述分配规则,将部分个数或全部个数存在碰撞的CSI报告分配给第一CSI PUCCH;进行所述部分个数或全部个数存在碰撞的CSI报告的传输;能够根据分配规则正确的将存在碰撞的多个基于PUCCH的CSI报告分配至网络设备配置的多个multi-CSI PUCCH中的至少一个上,不再是单纯的按照各CSI报告的优先级发送一个高优先级的CSI报告而丢弃其它低优先级的CSI报告,可以在一定程度上避免网络侧获取一些CSI报告不及时或缺失,解决相关技术中多个基于PUCCH的CSI报告发生碰撞时丢弃CSI报告造成网络侧获取CSI报告不及时或CSI报告缺失的问题,保证了网络通信的可靠性。
具体的,所述根据所述分配规则,将部分个数或全部个数存在碰撞的CSI报告分配给第一CSI PUCCH,包括:根据配置的第一CSI PUCCH的个数J确定可选用的第一CSI PUCCH的个数上限N;从配置的J个第一CSI PUCCH中选取M个第一CSI PUCCH;
将部分个数或全部个数存在碰撞的CSI报告分配给选取的M个第一CSI PUCCH;其中,J为大于或等于1的整数,N为大于或等于1、且小于或等于J的整数,M为大于或等于1、且小于或等于N的整数,J、N以及M中的至少一项为网络设备配置的或者协议约定的。
其中,所述分配规则为在同一个预设时间段内当为终端配置有至少两个第一CSI PUCCH时,选择至少一个第一CSI PUCCH进行部分个数或全部个数存在碰撞的CSI报告的分配。
预设时间段可具体为一个时隙。
针对为终端配置的J个第一CSI PUCCH的资源大小相同或不同,本公开实施例提供以下两种示例:
第一种,在为终端配置的J个第一CSI PUCCH的资源大小相同时,所述将部分个数或全部个数存在碰撞的CSI报告分配给选取的M个第一CSI PUCCH,包括:将所述至少两个CSI报告按照优先级由高到低依次分配到选取的M个第一CSI PUCCH上,直至至少两个CSI报告分配完毕或者直至选取的M个第一CSI PUCCH占用完毕。
具体的,为终端配置的J个第一CSI PUCCH的时域资源不同,即多个第一CSI PUCCH占用不同的时域OFDM符号。资源大小相同是指任意两个第一CSI PUCCH占用的RE数相同,即占用的OFDM符号数与频域子载波数的乘积相同。
第二种,在为终端配置的至少两个第一CSI PUCCH的资源大小不同时,所述从配置的J个第一CSI PUCCH中选取M个第一CSI PUCCH,包括:
从配置的J个第一CSI PUCCH中获取满足所述至少两个CSI报告所需资源的M个第一CSI PUCCH,且所述M个第一CSI PUCCH的资源大小总和大于所述至少两个CSI报告所需资源、且与所述至少两个CSI报告所需资源最接近、且所述M的数值最小。
具体的,为终端配置的J个第一CSI PUCCH的时域资源不同,即多个第一CSI PUCCH占用不同的时域OFDM符号。资源大小不同是指任意两个第一CSI PUCCH占用的RE数不同,即占用的OFDM符号数与频域子载波数的乘积不同。
对应的,所述将部分个数或全部个数存在碰撞的CSI报告分配给选取的M个第一CSI PUCCH,包括:根据CSI报告优先级,将所述至少两个CSI报告进行降序排列,得到第一顺序;根据资源大小,将获取到的所述M个第一CSI PUCCH进行降序排列,得到第二顺序;
将所述至少两个CSI报告按照所述第一顺序依次分配至按照所述第二顺序排列的所述M个第一CSI PUCCH上,直至至少两个CSI报告分配完毕或者直至第一CSI PUCCH占用完毕。
即可选占用一个第一CSI PUCCH,放不下所述至少两个CSI报告再占用 第二个第一CSI PUCCH,所述至少两个CSI报告要先放优先级高的,直到所述至少两个CSI报告放完为止或选取的M个第一CSI PUCCH放置满(占用完)为止。
也就是,本公开实施例的方案可包括:
网络设备可以配置J个第一CSI PUCCH资源,但在一个时隙内最多可以使用N≥1个第一CSI PUCCH进行传输;配置的J个第一CSI PUCCH的资源(时域)不同,资源大小相同或不同;假设发生碰撞的CSI报告数目为K。
根据预设规则(可以是网络设备配置的)将能够传输的X个CSI报告(X大于或等于1,且小于或等于K)放置到1≤M≤N个第一CSI PUCCH上;
J个第一CSI PUCCH资源大小不同时,选择M个第一CSI PUCCH资源总和与K个CSI报告所需资源最接近的、使得M最小的多个第一CSI PUCCH资源。具体地,将K个发生碰撞的CSI报告排序(例如按优先级)。
1)首先寻找一个能够容纳K个CSI报告所需资源的最小资源大小的第一CSI PUCCH。如果能够找到这样的一个第一CSI PUCCH,M=1;否则,按照CSI报告排序放置到资源最大的第一CSI PUCCH上,假设资源大小最大的第一CSI PUCCH可以放置X1<K个CSI报告;若N=1,M=N,则结束;否则,执行2)
2)继续寻找一个能够容纳剩下的K-X1个CSI报告所需资源的最小资源大小的第一CSI PUCCH。如果能够找到这样的一个第一CSI PUCCH,则M=2,结束;否则,按照CSI报告排序放置到剩余的资源最大的第一CSI PUCCH上,假设可以放置X2<K-X1个CSI报告;若N=2,M=N,则结束;否则,执行3)。
3)剩下的K-X1-X2个CSI报告以此类推进行放置,直到K个CSI报告放完为止或N第一CSI PUCCH占满为止(即M=N)。
进一步的,在将部分个数或全部个数存在碰撞的CSI报告分配给第一CSI PUCCH之前,所述传输方法还包括:获取第一CSI PUCCH的周期;其中,所述周期由网络设备指示或所述周期由终端根据所述至少两个CSI报告的周期的最小公倍数确定;
其中,在所述周期由网络设备指示时,所述周期的取值根据无线资源控 制RRC配置的所述至少两个CSI报告的预设信息的周期的最小值确定;或者所述周期的取值由网络设备根据所述至少两个CSI报告的周期的最小公倍数确定;
其中,所述预设信息包括:周期CSI报告设置信息或半持续CSI报告设置信息;
进一步,所述根据所述分配规则,将部分个数或全部个数存在碰撞的CSI报告分配给第一CSI PUCCH,包括:根据所述周期和所述分配规则,将部分个数或全部个数存在碰撞的CSI报告分配给第一CSI PUCCH。
在此说明,本公开实施例中,多CSI PUCCH的周期可以由RRC或媒体接入控制层控制单元(MAC CE)显式配置或隐式获得:
1)显式配置
1-1)以RRC配置的所有P-CSI report setting或SP-CSI report setting的最小周期值确定。
1-2)隐式获得:
1-2-1)根据发生碰撞的各个基于PUCCH的CSI报告的周期的最小公倍数确定一个多CSI PUCCH的周期。
本公开实施例中,还可以不配置周期,只要发生基于PUCCH的CSI报告碰撞,就使用多CSI PUCCH(碰撞很可能是非均匀的)。
本公开实施例中,第一CSI PUCCH可包括多个不同周期的第一CSI PUCCH。
考虑到第一CSI PUCCH与PUCCH、PUSCH、SRS发生碰撞时的行为,本公开实施例中,在进行所述部分个数或全部个数存在碰撞的CSI报告的传输时,所述传输方法还包括以下步骤中的至少一项:
在第一CSI PUCCH与携带混合自动重传应答HARQ-ACK的PUCCH发生碰撞时,将HARQ-ACK在所述第一CSI PUCCH上传输;
在所述第一CSI PUCCH与物理上行链路共享信道PUSCH发生碰撞时,将第一CSI PUCCH上的CSI报告在PUSCH上传输(也就是多CSI PUCCH借助(piggyback)PUSCH发送);
在所述第一CSI PUCCH与信道探测参考信号(Sounding Reference Signal, SRS)发生碰撞时,根据第一CSI PUCCH携带的信息、第一CSI PUCCH的周期特性以及SRS的周期特性,确定传输第一CSI PUCCH或者SRS。
也就是,本公开实施例还定义了多CSI PUCCH与PUCCH、PUSCH、SRS发生碰撞时的行为。当发送多CSI PUCCH时,
1)多CSI PUCCH与携带混合自动重传请求确认(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)的PUCCH发生碰撞时,HARQ-ACK信息在多CSI PUCCH上传输;
2)多CSI PUCCH与PUSCH发生碰撞,多CSI PUCCH借助(piggyback)PUSCH发送;
3)多CSI PUCCH与SRS发生碰撞,按照PUCCH与SRS的复用原则(根据PUCCH携带的信息与周期特性,以及SRS的周期特性来决定)处理。
为了提高资源的利用率,第一CSI PUCCH当在PUCCH上传输的CSI报告发生碰撞时进行使用;当在PUCCH上传输的CSI报告无碰撞时,第一CSI PUCCH占用的资源分配给物理上行链路共享信道PUSCH、信道探测参考信号SRS或除第一CSI PUCCH外的其他PUCCH。
即多CSI PUCCH只有在基于PUCCH的CSI报告碰撞时才会使用,无碰撞时多CSI PUCCH占用的资源可以分配给其他PUCCH或PUSCH或SRS。
具体的,本公开实施例中,所述至少两个CSI报告的编码方式包括以下方式中的至少一项:
所述至少两个CSI报告在所述第一CSI PUCCH分别进行编码;
所述至少两个CSI报告的第一部分统一编码,所述至少两个CSI报告的第二部分统一编码。
也就是,本公开实施例中,所述至少两个CSI报告(具体是指能够传输的CSI报告)的编码方案可以是以下方式中的至少一种:
1)能够传输的所有CSI报告的编码方案仍按各自原PUCCH的编码方案;
其中,仍按各自原PUCCH的编码方案具体是指CSI part 1与CSI part 2(如果有)分别编码,且3bit<CSI part 1或CSI part 2<11bit,用RM码;CSI part 1或CSI part 2>11bit用Polar码(极化码)。
2)能够传输的所有CSI报告的CSI part 1按照相关技术中的规则统一编 码,CSI part 2按照相关技术中的规则统一编码;
其中,相关技术中的规则是指CSI part 1与CSI part 2(如果有)分别编码,且3bit<CSI part 1或CSI part 2<11bit,用RM码;CSI part 1或CSI part2>11bit用Polar码(极化码)。
由上可知,本公开实施例提供的方案对引入的多CSI PUCCH的一些实施细节进行了说明,可以保证网络通信的可靠性。

进一步地,多个CSI报告发生碰撞时,按照各CSI报告的优先级进行丢弃,可能会造成网络侧获取一些CSI报告不及时或缺失。当这些碰撞的CSI报告在包含较大资源的PUSCH上传输时,可以传输多个CSI报告而不是简单地丢弃。
通常,信道状态信息(CSI)报告可以进行如下配置:
1)周期CSI报告(P-CSI):仅在PUCCH上传输;
2)半持续CSI报告(SP-CSI):在PUCCH或PUSCH上传输;
3)非周期CSI报告(AP-CSI):仅在PUSCH上传输。
优先级规定:当同一个载波上两个CSI报告所使用的PUSCH资源在时域上至少有一个OFDM符号重叠,那么这两个CSI报告便发生碰撞。每个CSI报告对应一个优先级值,发生CSI报告碰撞或上行传输资源有限的情况下终端则不发送优先级值高(或低)的一些CSI报告。
规则1:依据时域行为/信道类型(AP-CSI>SP-CSI on PUSCH>SP-CSI on PUCCH>P-CSI)
规则2~4仅适用于基于PUCCH传输的P-CSI和SP-CSI:
规则2:CSI内容(Beam reports>CSI);
规则3:cell ID(PCell>PSCell>按升序排列的其他cell ID);
规则4:csiReportID(升序排列)。
CSI报告分为Type I和Type II:
1)Type I的CSI报告最多分成两部分:
Part 1包含RI/CRI、第一个码字的CQI;
Part 2包含PMI和当RI>4时的第二个码字的CQI。
2)Type II的CSI报告最多分成两部分:
Part 1具有固定的载荷长度用于指示Part 2的比特长度,包含RI、CQI和每层非零宽带幅度系数的数目;
Part 2则包含Type II的PMI。
除了Type I和Type II的CSI报告,还有用于波束管理的波束信息报告“CRI/RSRP”和“SSBRI/RSRP”等,此时的CSI报告仅有一个部分。
当物理上行链路共享信道(PUSCH)上的CSI报告包括两部分(Part 1和Part 2)时,终端可以丢弃Part 2的部分内容不上报。在一个时隙内共有N个CSI报告,N为对应的配置报告(ReportConfig)中包含的CSI报告数量。当在PUSCH上报告的CSI与上行数据同时传输且PUSCH空间不能容纳完整的CSI报告内容时,Part 2的CSI部分内容会被逐级丢弃,丢弃优先级如下:优先级0为最高优先级,即优先发送的CSI报告内容;优先级2N为最低优先级,即最先丢弃的CSI报告内容。丢弃时把优先级层的CSI报告内容整体丢弃。
如果传输CSI报告的PUCCH与传输上行数据的PUSCH发生碰撞,PUCCH的CSI报告可以借助(piggyback)在PUSCH上传输,此时PUSCH的CSI报告的编码方式和CSI报告的丢弃方式与原先在PUCCH一致。
相关技术中的协议规定了当PUSCH上发送CSI报告和上行数据如何分配资源,以及CSI报告映射的位置等规则。
相关技术中关于CSI报告发生碰撞的处理描述如下:当终端被配置发送两个碰撞的CSI报告时,适用如下规则:终端不发送优先级取值较高的CSI报告(即对应于低优先级的CSI报告)。
然而,在某些情况下,在PUSCH上用于传输CSI报告的资源较大,可以传输更多的CSI报告。而不是简单地丢弃CSI报告。
在以下情况会出现CSI报告发生碰撞并且在PUSCH上传输:
1)基于PUSCH的AP-CSI报告与基于PUSCH的SP-CSI报告发生碰撞;
2)基于PUSCH的AP-CSI报告与上行共享信道(UL-SCH)在同一个PUSCH上传输;
3)基于PUSCH的SP-CSI报告与UL-SCH在同一个PUSCH上传输;
4)基于PUCCH的P-CSI报告或SP-CSI报告与基于PUSCH的AP-CSI报告或SP-CSI报告发生碰撞;
5)基于PUCCH的P-CSI报告或SP-CSI报告与调度UL-SCH的PUSCH发生碰撞时,PUCCH的P-CSI报告或SP-CSI报告会借助PUSCH传输;
6)基于PUCCH的P-CSI报告或SP-CSI报告与包含基于PUSCH的AP-CSI报告或SP-CSI报告和UL-SCH的PUSCH发生碰撞。
相关技术中,当多个CSI报告(即至少两个CSI报告)发生碰撞时,按照各CSI报告的优先级进行丢弃,可能会造成网络侧获取一些CSI报告不及时或缺失。当这些碰撞的CSI报告在包含较大资源的PUSCH上传输时,可以传输多个CSI报告而不是简单地丢弃。
当K>1个CSI报告(包括基于PUCCH的CSI报告和/或基于PUSCH的CSI报告,即至少两个CSI报告)发生碰撞时,并且在PUSCH上传输的处理方法包括以下方式:
方式一、
按照相关技术中的优先级规则发送至少两个CSI报告中优先级最高的一个CSI报告,丢弃其他CSI报告。确定PUSCH上用于传输该CSI报告的资源大小并按预设规则将该优先级最高的CSI报告映射PUSCH上相应的时频位置发送;
需要说明的是,该预设规则为按照资源大小的优先级排列,在排序完成后,将优先级最高的一个CSI报告映射到PUSCH上相应的时频位置上。
方式二、
选取X≤K个高优先级的CSI报告映射到PUSCH上相应的时频位置发送,即在发生碰撞的至少两个CSI报告中,按照CSI报告优先级由高到低的顺序,选取发生碰撞的至少两个CSI报告中的部分或全部CSI报告。
具体实现方式包括以下方式中的至少一项:
1)确定待传输每个CSI报告所需的资源大小,以及PUSCH上可以用于传输CSI报告的资源大小,将X≤K个CSI报告放置到PUSCH上可以用于传输CSI报告的资源上;
需要说明的是,基于PUCCH的CSI报告在PUSCH上传输时仍按照PUCCH的编码方式进行编码。
2)K个高优先级的CSI报告放置到PUSCH分配给CSI报告的资源上,即将K个高优先级的CSI报告放置到PUSCH的资源上(具体可以按照优先级顺序(CSI报告的优先级顺序)放置,优先级值的确定按相关技术中的结论),具体实现可采用以下方式中的至少一项:
方式一:低优先级的每个CSI报告整体(包括part 1和part 2)丢弃,直到上行控制信息(UCI)的码率低于码率门限为止。
计算每个CSI报告的码率,与码率门限比较,如果存在报告的码率大于码率门限,则丢弃一个低优先级的CSI报告。依此类推,直到可传输的每个CSI报告的码率低于码率门限为止。
方式二:首先按优先级确定CSI报告的part 1的丢弃,再确定part 2的丢弃。需要说明的是,当一个CSI报告的Part 1被丢弃时,其对应的part 2也会被丢弃。若一个CSI报告的Part 1可以被发送,则其对应的Part 2可以根据相关技术中的方法逐级丢弃。
具体地,在进行part 1的丢弃时,计算每个CSI part 1的码率,与码率门限1比较,如果大于码率门限1,需要丢弃一个低优先级的CSI报告的part 1,直到可传输的每个CSI part 1的码率(或所有CSI part 1的码率)低于码率门限1为止;
在进行part 2的丢弃时,计算可传输的CSI part 1对应的各个CSI part 2的码率,与码率门限2比较,如果大于码率门限2,需要丢弃一个低优先级的CSI part 2的一部分。直到可传输的每个CSI part 2的码率(或所有CSI part1的码率)低于码率门限2为止。
需要说明的是,上述实现方式解决了在某些情况下多个CSI报告发生碰撞并且由PUSCH传输时利用其资源较多的优点传输更多的CSI报告,而不是简单地丢弃CSI报告,保证了网络通信的可靠性。
以上所述的是本公开的可选实施方式,应当指出对于本技术领域的普通人员来说,在不脱离本公开所述的原理前提下还可以作出若干改进和润饰,这些改进和润饰也在本公开的保护范围内。
