本申请主张在2018年3月30日在中国提交的中国专利申请号No.201810276613.6的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信领域,尤其涉及一种物理上行控制信道资源确定方法和通信设备。
背景技术
在传输反馈信息(HARQ-ACK/NACK,AN)/调度请求(Scheduling Request,SR)的物理上行控制信道(Physical Uplink Control Channel,PUCCH)和传输信道状态信号(Channel State Information,CSI)的PUCCH的时域位置有重叠部分的情况下,若传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号,终端设备(User Equipment,UE)将选择一个PUCCH资源来传输AN/SR和CSI。
在移动通信新空口(New Radio,NR)中,PUCCH资源按照可承载上行控制信息(Uplink Control Information,UCI)的大小分成不同的PUCCH资源集合(PUCCH Resource Set,PUCCH RESET)。例如,RESET0:可承载UCI比特数为0<UCI<=2;RESET1:可承载UCI比特数为2<UCI<=N2;RESET2:可承载UCI比特数为N2<UCI<=N3;RESET3:可承载UCI比特数为N3<UCI<=N4;其中,N4,N2,N3为正整数且由高层提供,N2<N3<N4。
一个UE可以配置一个或多个(最多4个)PUCCH资源集合,每个PUCCH资源集合中可包含多个PUCCH资源。当传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号时,UE首先根据AN/SR和CSI的比特数总和确定一个PUCCH资源集合,进而在该PUCCH资源集合中选择一个PUCCH资源来传输AN/SR和CSI。
但是,AN/SR和CSI的比特数总和并不固定,使得基站并不知道UE将 在哪个PUCCH资源集合中选择PUCCH资源来传输AN/SR和CSI,导致基站需要在所有可能的PUCCH资源进行盲检测。
发明内容

第八方面,本公开实施例还提供了一种计算机可读存储介质,所述计算机可读存储介质上存储计算机程序,所述计算机程序被处理器执行时实现如第二方面所述的方法的步骤。
在本公开实施例中,按照预设规则,确定CSI-part 2的参考比特数,根据CSI-part 2的参考比特数,确定AN/SR和CSI的参考比特数总和,其中,CSI至少包括:CSI-part 1和CSI-part 2,根据AN/SR和CSI的参考比特数总和,确定目标PUCCH资源集合,从而可以较准确地确定传输AN/SR和CSI所使用的PUCCH资源集合,有效地避免基站盲检测问题。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
参见图1,图1为本公开实施例提供的一种网络架构示意图。如图1所示,包括用户终端11和基站12,其中,用户终端11可以是UE,例如:可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定用户终端11的具体类型。上述基站12可以是5G及以后版本的基站(例如:gNB、5G NR NB),或者其他通信系统中的基站,或者称之为节点B,需要说明的是,在本公开实施例中仅以5G基站为例,但是并不限定基站12的具体类型。
需要说明的是,上述用户终端11和基站12的具体功能将通过以下多个实施例进行具体描述。
实施例1
图2为本公开实施例提供的一种物理上行控制信道资源确定方法的流程示意图。所述方法包括:
步骤S210,按照预设规则,确定CSI-part 2的参考比特数。
步骤S220,根据CSI-part 2的参考比特数,确定AN/SR和CSI的参考比特数总和。
其中,CSI至少包括:CSI-part 1和CSI-part 2。
步骤s230,根据AN/SR和CSI的参考比特数总和,确定目标PUCCH资源集合。
实际应用中,若传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号,则UE可以选择一个PUCCH资源来传输AN/SR和CSI。
需要说明的是,AN/SR表示包括AN,可以包括SR,也可以不包括SR。
图3为本公开实施例提供的传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号的示意图。
如图3所示,在某一相同时隙(slot)内,传输AN/SR的为8个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号的PUCCH,传输CSI的为7个OFDM符号的PUCCH,传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号。
实际应用中,UE可以配置一个或多个(最多4个)PUCCH资源集合。
图4为本公开实施例提供的UE配置的PUCCH资源集合的示意图。
如图4所示,UE配置有4个PUCCH资源集合:RESET0-RESET3,其中,RESET0可承载UCI比特数为0<UCI<=2bits、RESET1可承载UCI比特数为2<UCI<=11bits、RESET2可承载UCI比特数为11<UCI<=30bits、RESET3可承载UCI比特数为30<UCI<=N4bits。
若UE配置有多个PUCCH资源集合,UE需根据AN/SR和CSI的比特数总和,在配置的多个PUCCH资源集合中选择目标PUCCH资源集合,进而在该选中的目标PUCCH资源集合中确定传输AN/SR和CSI的目标PUCCH资源。
其中,CSI至少包括两部分:CSI-part 1和CSI-part 2。CSI-part 2的比特数与等级指示(Rank Indication,RI)有关,不同RI对应的CSI-part 2的比特数可能不同。由于基站并不知道UE将上报哪个RI,使得基站无法确定CSI-part 2的比特数,进而也无法确定AN/SR和CSI的比特数总和,导致基站无法确定UE将在哪个PUCCH资源集合中选择PUCCH资源来传输AN/SR和CSI。
本公开实施例中,若传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号,且CSI中包括CSI-part 2,则按照预设规则,确定CSI-part 2的参考比特数,其中,CSI-part 2的参考比特数用于确定UE在哪个PUCCH资源集合中选择PUCCH资源来传输AN/SR和CSI,使得基站和UE对于传 输AN/SR和CSI的PUCCH资源集合有相同的理解。
确定CSI-part 2的参考比特数的预设规则包括但不限于下述五种方式:
第一种:
根据不同RI对应的CSI-part 2的比特数,确定CSI-part 2的参考比特数;其中,CSI-part 2的参考比特数为不同RI对应的CSI-part 2的比特数中的最小比特数。
例如,某一时刻,不同RI对应的预编码矩阵指示(Precoding Matrix Indicator,PMI)的比特数如表1所示:
表1
RI PMI的比特数(bit)
RI=1 13
RI=2 13
RI=3或4 7
RI=5或6 5
RI=7或8 4
假设高层配置的参数n KI=8,
Figure PCTCN2019080080-appb-000001
则RI、信道质量指示(Channel Quality Indicator,CQI)和信道资源指示(Channel Resource Indicator,CRI)的比特数如表2所示:
表2
Figure PCTCN2019080080-appb-000002
根据表2可知,当RI=1~4时仅包括一个码字:第一个码字,且第一个码字的CQI的比特数=4;当RI=5~8时包括两个码字:第一个码字和第二个码字,且第一个码字的CQI的比特数=4,第二个码字的CQI的比特数=4。
因此,CSI-part 1的比特数=RI+CRI的比特数+第一个码字的CQI的比特数=3+3+4=10bit;CSI-part 2的比特数=PMI的比特数+第二个码字的CQI的比 特数,CSI-part 2的比特数如表3所示:
表3
Figure PCTCN2019080080-appb-000003
CSI-part 2的参考比特数为不同RI对应的CSI-part 2的比特数中的最小比特数,即CSI-part 2的参考比特数为7bit。
若AN/SR的比特数为10bit,则根据CSI-part 2的参考比特数,可以确定AN/SR和CSI的参考比特数总和=AN/SR的比特数+CSI-part 1的比特数+CSI-part 2的参考比特数=10+10+7=27bit。
若UE配置的PUCCH资源集合如图4所示,则根据AN/SR和CSI的参考比特数总和27bit,确定目标PUCCH资源集合为RESET2。
第二种:
根据不同RI对应的CSI-part 2的比特数,确定CSI-part 2的参考比特数;其中,CSI-part 2的参考比特数为不同RI对应的CSI-part 2的比特数中的最大比特数。
仍以上述表1-表3为例,CSI-part 2的参考比特数为不同RI对应的CSI-part 2的比特数中的最大比特数,即CSI-part 2的参考比特数为13bit。
若AN/SR的比特数为10bit,则根据CSI-part 2的参考比特数,可以确定AN/SR和CSI的参考比特数总和=AN/SR的比特数+CSI-part 1的比特数+CSI-part 2的参考比特数=10+10+13=33bit。
若UE配置的PUCCH资源集合如图4所示,则根据AN/SR和CSI的参考比特数总和33bit,确定目标PUCCH资源集合为RESET3。
第三种:
根据不同RI对应的CSI-part 2的比特数,确定CSI-part 2的参考比特数;其中,CSI-part 2的参考比特数为预设RI对应的CSI-part 2的比特数。
例如,预设RI对应的CSI-part 2的比特数小于不同RI对应的CSI-part 2 的比特数中的最大比特数,且大于不同RI对应的CSI-part 2的比特数中的最小比特数。
仍以上述表1-表3为例,假设预设RI为RI=5或6,则CSI-part 2的参考比特数为RI=5或6对应的CSI-part 2的比特数,即CSI-part 2的参考比特数为9bit,其中,RI=5或6对应的CSI-part 2的比特数9bit,小于不同RI对应的CSI-part 2的比特数中的最大比特数13bit,且大于不同RI对应的CSI-part 2的比特数中的最小比特数8bit。
可选地,预设RI的确定方式包括下述之一:
通过协议规定;
通过网络侧设备配置;
通过隐指示方式指定。
需要说明的是,预设RI的确定方式除了上述三种之外,还可以包括其他方式,这里不做具体限定。
若AN/SR的比特数为10bit,则根据CSI-part 2的参考比特数,可以确定AN/SR和CSI的参考比特数总和=AN/SR的比特数+CSI-part 1的比特数+CSI-part 2的参考比特数=10+10+9=29bit。
若UE配置的PUCCH资源集合如图4所示,则根据AN/SR和CSI的参考比特数总和33bit,确定目标PUCCH资源集合为RESET2。
第四种:
将UE上一次向网络侧设备上报的RI对应的CSI-part 2的比特数确定为CSI-part 2的参考比特数。
UE假设CSI-part 2的参考比特数是根据UE上一次上报给基站的RI得到的CSI-part 2的比特数。
仍以上述表1-表3为例,若UE上一次上报给基站的RI为RI=7,则CSI-part 2的参考比特数为根据RI=7得到的CSI-part 2的比特数,即CSI-part2的参考比特数为8bit。
若AN/SR的比特数为10bit,则根据CSI-part 2的参考比特数,可以确定AN/SR和CSI的参考比特数总和=AN/SR的比特数+CSI-part 1的比特数+CSI-part 2的参考比特数=10+10+8=28bit。
若UE配置的PUCCH资源集合如图4所示,则根据AN/SR和CSI的参考比特数总和33bit,确定目标PUCCH资源集合为RESET2。
第五种:
将CSI-part 2的参考比特数确定为0。
为了避免基站的盲检测,UE假设只有AN/SR,没有CSI-part 2,或者没有CSI,使得AN/SR和CSI的比特数总和固定。
在一实施例中,将CSI-part 2的参考比特数确定为0,即UE假设只有AN/SR和CSI-part 1,没有CSI-part 2。
仍以上述表1-表2为例,若AN/SR的比特数为10bit,可以确定AN/SR和CSI的参考比特数总和=AN/SR的比特数+CSI-part 1的比特数+CSI-part 2的参考比特数=10+10+0=20bit。
若UE配置的PUCCH资源集合如图4所示,则根据AN/SR和CSI的参考比特数总和20bit,确定目标PUCCH资源集合为RESET2。
在另一实施例中,将CSI-part 2的参考比特数确定为0,且将CSI-part 1的参考比特数也确定为0,即UE假设只有AN/SR,没有CSI。
若AN/SR的比特数为10bit,可以确定AN/SR和CSI的参考比特数总和=AN/SR的比特数+CSI-part 1的参考比特数+CSI-part 2的参考比特数=10+0+0=10bit。
若UE配置的PUCCH资源集合如图4所示,则根据AN/SR和CSI的参考比特数总和10bit,确定目标PUCCH资源集合为RESET1。
当上述确定目标PUCCH资源集合的方法应用于UE时,UE在确定目标PUCCH资源集合之后,还包括:
根据下行控制信令(Downlink Control Information,DCI)中包括的确认资源指示(ARI),在目标PUCCH资源集合中确定目标PUCCH资源;
根据目标PUCCH资源,传输AN/SR和CSI。
对于承载UCI比特数较少(小于等于2bit)的目标PUCCH资源集合,包含至少8个(最多32个)PUCCH资源:
如果目标PUCCH资源集合内的PUCCH资源多于8个,则可以通过3bit ARI+隐示指示的方式确定传输AN/SR和CSI的目标PUCCH资源;
如果目标PUCCH资源集合内的PUCCH资源为8个,则可以通过3bit ARI的方式确定传输AN/SR和CSI的目标PUCCH资源。
对于承载比特数较多(大于2bit)的PUCCH资源集合,包含8个PUCCH资源,可以通过3bit ARI的方式确定传输AN/SR和CSI的目标PUCCH资源。
当上述确定目标PUCCH资源集合的方法应用于网络侧设备时,网络侧设备在确定目标PUCCH资源集合之后,还包括:
根据DCI中包括的ARI,在目标PUCCH资源集合中确定目标PUCCH资源;
在目标PUCCH资源上进行检测。
网络侧设备确定目标PUCCH资源之后,即知道了UE将在目标PUCCH资源上传输AN/SR和CSI,因此,网络侧设备可以在目标PUCCH资源上进行检测,而无需在所有的PUCCH资源上进行盲检测。
本公开实施例记载的技术方案,按照预设规则,确定CSI-part 2的参考比特数,根据CSI-part 2的参考比特数,确定AN/SR和CSI的参考比特数总和,其中,CSI至少包括:CSI-part 1和CSI-part 2,根据AN/SR和CSI的参考比特数总和,确定目标PUCCH资源集合,从而可以较准确地确定传输AN/SR和CSI所使用的PUCCH资源集合,有效地避免基站盲检测问题。
实施例2
图5为本公开实施例提供的另一种物理上行控制信道资源确定方法的流程示意图。所述方法包括:
步骤S510,若CSI中包括CSI-part 2,则将预设PUCCH资源集合确定为目标PUCCH资源集合。
UE和基站确定一个预设PUCCH资源集合,使得若传输AN/SR的PUCCH和传输CSI的PUCCH有相同的起始符号,且CSI中包括CSI-part 2,则可以将该预设PUCCH资源集合确定为目标PUCCH资源集合,使得基站和UE对于传输AN/SR和CSI的PUCCH资源集合有相同的理解。
可选地,预设PUCCH资源集合与其他PUCCH资源集合相比,可承载UCI的比特数最大。
例如,将可承载UCI的比特数最大的RESET3确定为预设PUCCH资源集合。
需要说明的是,预设PUCCH资源集合除了可以是可承载UCI的比特数最大的PUCCH资源集合之外,还可以是其他PUCCH资源集合,这里不做具体限定。
当上述确定目标PUCCH资源集合的方法应用于UE时,UE在确定目标PUCCH资源集合之后,还包括:
根据DCI中包括的ARI,在目标PUCCH资源集合中确定目标PUCCH资源;
根据目标PUCCH资源,传输AN/SR和CSI。
对于承载UCI比特数较少(小于等于2bit)的目标PUCCH资源集合,包含至少8个(最多32个)PUCCH资源:
如果目标PUCCH资源集合内的PUCCH资源多于8个,则可以通过3bit ARI+隐示指示的方式确定传输AN/SR和CSI的目标PUCCH资源;
如果目标PUCCH资源集合内的PUCCH资源为8个,则可以通过3bit ARI的方式确定传输AN/SR和CSI的目标PUCCH资源。
对于承载比特数较多(大于2bit)的PUCCH资源集合,包含8个PUCCH资源,可以通过3bit ARI的方式确定传输AN/SR和CSI的目标PUCCH资源。
当上述确定目标PUCCH资源集合的方法应用于网络侧设备时,网络侧设备在确定目标PUCCH资源集合之后,还包括:
根据DCI中包括的ARI,在目标PUCCH资源集合中确定目标PUCCH资源;
在目标PUCCH资源上进行检测。
网络侧设备确定目标PUCCH资源之后,即知道了UE将在目标PUCCH资源上传输AN/SR和CSI,因此,网络侧设备可以在目标PUCCH资源上进行检测,而无需在所有的PUCCH资源上进行盲检测。
本公开实施例记载的技术方案,若CSI中包括CSI-part 2,则将预设PUCCH资源集合确定为目标PUCCH资源集合,从而可以较准确地确定传输AN/SR和CSI所使用的PUCCH资源集合,有效地避免基站盲检测问题。
