为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。 本申请实施例包括以下内容中的至少部分内容。
在相关技术中,TS38.213中9.2.1节针对无线资源控制(Radio Resource Control,RRC)连接建立前和RRC连接建立后分别进行了规定了物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)资源集合的确定方式。
在RRC连接建立前,UE无法通过高层RRC信令获得PUCCH资源配置,因此TS 38.213以如下表1中行索引的方式在上行初始带宽部分(Band Width Part,BWP)中预定义了16组公共PUCCH资源集合,即每组PUCCH资源集合对应表格的一行。
表1
Figure PCTCN2021098322-appb-000001
在预定义的多组PUCCH资源集合中,每组PUCCH资源集合都包含16个PUCCH资源,其中每个PUCCH资源对应一个PUCCH格式、起始符号(即第一个符号)、符号个数、PRB偏移和循环移位(cyclic shift,CS),以进行多用户复用。
在RRC连接建立之后,UE可以通过高层信令获得网络设备配置的一个或多个PUCCH资源,从而进行PUCCH传输。
在相关技术中,PUCCH0/1/4只支持在一个物理资源块(physical resource block,PRB)上的传输,法规通常对上行传输进行一些限制,以避免UE之间的干扰,例如在60GHz的非授权频段上,法规通常对最大功率谱密度(power spectral density,PSD)和等效全向辐射功率(equivalent isotropically radiated power,EIRP)进行限制,此时,传统的功率提升方案无法达到法规允许的最大发射功率,导致PUCCH传输覆盖性能受限。
在一些实现方式中,考虑在功率谱密度限制条件下考虑增加PUCCH传输可配置的PRB数,此情况下,如何实现在这些PRB上的PUCCH传输以提升上行传输覆盖性能是一项亟需解决的问题。
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,该方法200可以由图1所示的通信系统中的终端设备执行,如图2所示,该方法200包括如下内容:
S210,终端设备确定物理上行控制信道PUCCH对应的目标PUCCH资源,所述PUCCH资源包括目标物理资源块PRB数个PRB中的每个PRB上的至少一个资源元素RE,所述目标PRB数为大于或等于1的正整数;
S220,所述终端设备通过所述目标PUCCH资源传输所述PUCCH。
对应地,网络设备接收终端设备通过所述目标PUCCH资源发送的所述PUCCH。
应理解,本申请实施例可以适用于确定非授权频谱上的PUCCH资源,或者也可以适用于确定授权频谱上的PUCCH资源,本申请对于具体的应用场景不作限定。
在本申请实施例中,所述终端设备可以为非连接态的终端设备,例如空闲态或非激活态,或者,也可以是连接态的终端设备。即所述PUCCH资源可以为用于非连接态的终端设备传输PUCCH的PUCCH资源,或者,也可以为用于连接态的终端设备传输PUCCH的PUCCH资源。
也就是说,本申请实施例中的PUCCH传输对应的目标PUCCH资源的确定方式可以用于确定初始接入阶段的PUCCH传输对应的目标PUCCH资源,或者也可以用于确定连接阶段的PUCCH传输对应的目标PUCCH资源。
在本申请实施例中,所述PUCCH可以为第一PUCCH格式,所述第一PUCCH格式例如可以包 括但不限于PUCCH格式0,PUCCH格式1和PUCCH格式4。
需要说明的是,在本申请实施例中,在目标PUCCH资源包括的每个PRB中,所述目标PUCCH资源可以占用PRB中的所有资源元素(Resource Element,RE),或者,也可以占用PRB中的部分RE。即所述目标PUCCH资源所占用的RE可以是以按照一定的梳齿间隔(interlace)分布的,该梳齿间隔可以为1个RE,或2个RE,或者12个RE等。
应理解,在本申请实施例中,当所述目标PRB数大于1时,所述目标PRB数个PRB可以是连续的多个PRB,或者也可以是不连续的多个PRB,本申请对此不作限定。
需要说明的是,该目标PRB数个PRB是连续的PRB,可以指:所述目标PUCCH资源占用的PRB是连续的,但是目标PUCCH资源在PRB内所占用的RE并不一定是连续的,例如可以是按照一定的梳齿间隔分布的,该梳齿间隔可以大于1个RE。
以下,结合具体实施例,说明所述目标PUCCH资源的确定方式。
实施例一
在本申请一些实施例中,所述S210可以包括:
所述终端设备根据预设规则和/或网络设备的指示信息,确定所述目标PRB数N RB
为便于区分和说明,将终端设备可以基于预设规则,确定的用于PUCCH传输的PRB数上限,或者说,可配置的PRB上限,记为第一PRB数。
在一些实施例中,所述预设规则可以包括协议约定的规则,例如,协议中规定的一些限制条件,该限制条件约束PUCCH传输的最大PRB数,此情况下,终端设备可以基于该限制条件,确定第一PRB数。
在另一些实施例中,所述预设规则可以包括国家的法规要求或者频谱的使用规范,例如,非授权频谱上的资源的使用规范。例如,为了避免对其他使用非授权频谱资源的系统造成强干扰,通常会对使用非授权频谱资源的终端设备的最大发射功率或最大发射功率谱密度进行限制。例如,欧洲的法规规定了非授权频谱上的信号的最大发射功率、功率谱密度和EIRP等限制条件。
在一些实施例中,所述终端设备根据预设规则,确定所述目标PRB数,包括:
所述终端设备根据所述预设规则,确定第一PRB数;
将所述第一PRB数确定为缺省目标PRB数。
例如,在未接收到网络设备的指示信息的情况下,所述终端设备可以使用所述缺省目标PRB数进行PUCCH传输。作为示例,非连接态的终端设备可以将缺省目标PRB数作为用于初始接入阶段的PUCCH传输的目标PRB数。
在一些实施例中,网络设备也可以根据所述预设规则,确定所述第一PRB数。
应理解,网络设备和终端设备根据所述预设规则确定第一PRB数的方式类似,以下,以网络设备根据预设规则确定第一PRB数为例进行说明。
例如,所述网络设备根据所述预设规则和第一子载波间隔,确定所述第一PRB数。
可选地,所述第一子载波间隔可以是预定义的子载波间隔,或者,网络设备指示的子载波间隔,或者,初始子载波间隔,或者默认子载波间隔等。
例如,所述第一子载波间隔为120kHz,480kHz,960kHz等。
在一些实施例中,所述网络设备可以根据法规规定的PSD和EIRP上限,确定达到该PSD和EIRP上限的带宽,进一步根据该带宽和所述第一子载波间隔确定所述第一PRB数。
例如,欧洲的法规要求,即EN302 567中规定的功率谱密度和EIRP上限分别为23dBm/MHz和40dBm,即PSD=23dBm/MHz,max(EIRP)=40dBm,计算达到PSD和EIRP上限的带宽BW=10 (max(EPRP)-PSD)/10=10 (40-23)/10=50MHz。
当第一子载波间隔等于120kHz时,PRB带宽根据第一子载波间隔和一个PRB上的子载波数
Figure PCTCN2021098322-appb-000002
确定,例如,在第一子载波间隔为120kHz,一个PRB上的子载波数为12时,PRB带宽为120kHz*12=1.44MHz,此情况下,可配置的PRB数上限
Figure PCTCN2021098322-appb-000003
同理可得,在第一子载波间隔等于480kHz时,可配置的PRB数上限为8;当第一子载波间隔等于960kHz时,可配置的PRB数上限为4。
在一些实施例中,网络设备可以将根据法规规定和第一子载波间隔计算得到的可配置的PRB数上限max(N RB)作为所述第一PRB数,或者,也可以将所述可配置的PRB数上限max(N RB)转化成不超过max(N RB)的2进制数,将该2进制数作为所述第一PRB数。例如,第一子载波间隔为120kHz时,可以将可配置的PRB数上限34作为第一PRB数,或者也可以将32作为第一PRB数。
在一些实施例中,所述网络设备可以根据第一候选PRB数集合确定所述目标PRB数。
在一些实施例中,所述第一候选PRB数集合可以是预配置的,或者说,预定义的,例如,可以将所述第一候选PRB数集合预设或者预先保存在所述网络设备中。
在一些实施例中,所述终端设备中也预配置有所述第一候选PRB数集合。
在一些实施例中,所述第一候选PRB数集合在网络设备和终端设备中可以以表格或列表等方式存储,本申请对于所述第一候选PRB数集合的存储方式不作限定。以下,以第一候选PRB数集合以表格方式存储为例进行说明,但本申请并不限于此。
在一些实施例中,所述第一候选PRB数集合用于确定非连接态的终端设备的PUCCH传输所使用的目标PRB数。换言之,所述第一候选PRB数集合用于确定初始接入阶段的PUCCH传输对应的目标PRB数。
在一些实施例中,所述第一候选PRB数集合中的候选PRB数根据所述第一PRB数设计。
例如,所述第一候选PRB数集合中包括至少一个候选PRB数,所述至少一个候选PRB数中的每个候选PRB数均不超过第一PRB数。
在一些实施例中,所述第一候选PRB数集合中的每个候选PRB数对应一个索引,所述网络设备确定目标PRB数之后,可以向终端设备指示所述目标PRB数对应的索引,从而,终端设备可以根据所述索引查询所述第一候选PRB数集合对应的表格,将所述索引对应的候选PRB数作为目标PRB数。
在一些实施例中,所述第一候选PRB数集合中的候选PRB数的粒度大于或等于一个PRB。
在一些实施例中,所述第一候选PRB数集合中的候选PRB数之间间隔的PRB数不等。即候选PRB数是分布不均的。
由于在候选PRB数较少时,候选PRB数的增多对发射功率的提升效果明显,在候选PRB数较多时,候选PRB数的增多对发射功率的提升效果不明显,也就是说,在候选PRB数增大到一定程度,再增加PRB数,发射功率提升效果有限,因此可以设置第一候选PRB数集合中的较小的候选PRB数之间的间隔较小,较大的候选PRB数之间的间隔较大。通过设置候选PRB数的粒度大于1个PRB,并且是分布不均匀的,有利于兼顾系统开销和覆盖性能。
作为示例,若根据预设规则确定第一PRB数为32,则所述第一候选PRB数集合包括的候选PRB数可以如表2所示。

在一些实施例中,网络设备在未与终端设备建立RRC连接前,网络设备可以根据所述第一候选PRB数集合确定所述目标PRB数。例如,在所述第一候选PRB数集合中选择一个候选PRB数作为所述目标PRB数。
在一些实施例中,所述网络设备可以根据初始上行BWP(initial UL BWP)支持的PRB数确定所述目标PRB数。
如前所述,用于初始接入阶段的PUCCH传输的一组PUCCU资源集合包括K个PUCCH资源,该K个PUCCH资源通过频分复用和码分复用方式实现,其中,码分复用的能力根据初始CS索引的个数N cs确定,频分复用的能力根据initial UL BWP的大小和PRB带宽的大小确定。
在一些实施例中,所述用于初始接入的一组PUCCH资源集合包括的PUCCH资源的总数K为16,以下以K为16为例进行说明,但本申请并不限于此。
在一些实施例中,网络设备可以计算以所述第一PRB数作为每个PUCCH资源占用的目标PRB数的情况下,基于所述初始上行BWP支持的PRB数和PUCCH资源的码分复用能力是否能够支持一组PUCCH资源集合中的全部PUCCH资源。
例如,在基于初始上行BWP的频分复用能力和码分复用能力不能支持一组PUCCH资源集合中的全部PUCCH资源的情况下,网络设备可以根据所述初始上行BWP支持的PRB数和PUCCH资源的码分复用能力确定每个PUCCH资源能够占用的最大PRB数。进一步地,根据所述每个PUCCH资源能够占用的最大PRB数确定所述目标PRB数。例如,网络设备可以根据所述每个PUCCH资源能 够占用的最大PRB数在所述第一候选PRB数集合中确定目标PRB数。作为一个示例,将所述第一候选PRB数集合中不超过所述每个PUCCH资源能够占用的最大PRB数的候选PRB数作为目标PRB数。
以第一子载波间隔为120kHz,N cs为2举例说明,若initial UL BWP需要支持PUCCH在该多个PUCCH资源中的每个PUCCH资源上均以max(N RB)个PRB数进行传输,该initial UL BWP需要支持的PRB数为(16/N cs)*max(N RB),即该initial UL BWP需要支持的PRB数为(16/2)*34=272个PRB。
当initial UL BWP为100MHz,第一子载波间隔为120kHz时,initial UL BWP理论上仅支持
Figure PCTCN2021098322-appb-000004
个PRB,不能支持272个PRB。也就是说,网络设备不能将第一PRB数作为终端设备用于PUCCH传输的目标PRB数,此情况下,网络设备可以根据初始上行BWP实际支持的PRB数和PUCCH资源的码分复用能力对所述第一PRB数进行调整,以确定目标PRB数。
例如,网络设备可以根据如下公式确定每个PUCCH资源占用的最大PRB数
Figure PCTCN2021098322-appb-000005
进一步可以根据该最大PRB数确定所述目标PRB数。
例如,网络设备可以在第一候选PRB数集合确定不超过该最大PRB数的候选PRB数作为目标PRB数。以表2所示的第一候选PRB数集合为例,可以确定目标PRB数为8。在另一些实施例中,若最大PRB数为10,则结合表2所示的第一候选PRB数集合,也可以确定目标PRB数为8。
进一步地,网络设备可以向终端设备发送指示信息,所述指示信息用于指示非连接态的终端设备传输PUCCH所使用的PRB数,或者说,所述指示信息用于指示初始接入阶段的PUCCH传输所使用的PRB数。例如,所述指示信息可以用于指示所述目标PRB数。
在一些实施例中,所述网络设备可以通过系统消息指示所述目标PRB数。例如,所述系统消息可以包括系统信息块(System Information Block,SIB)1。
结合图3,说明初始接入阶段的用于PUCCH传输的目标PRB数的确定方式。如图3所示,可以包括如下步骤:
S211,网络设备基于预设规则,确定第一PRB数;
S221,终端设备基于预设规则,确定第一PRB数。
应理解,本申请并不限定S211和S221的执行顺序。
其中,S211和S221的具体实现参考前文实施例的相关描述,这里不再赘述。
进一步地,S212,网络设备根据第一候选PRB数集合确定用于初始接入阶段的PUCCH传输所使用的目标PRB数。
S213,网络设备向终端设备发送该用于初始接入阶段的PUCCH传输所使用的目标PRB数。例如,通过系统消息发送给目标PRB数。
其中,S212和S213的具体实现参考前文实施例的相关描述,这里不再赘述。
在本申请一些实施例中,网络设备与终端设备建立RRC连接后,网络设备还可以根据终端设备的能力(例如硬件条件)和/或当前的信道条件等信息,确定用于PUCCH传输的目标PRB数。
作为示例一,终端设备可以向网络设备上报该终端设备的PUCCH传输支持的最大PRB数,记为第二PRB数,该第二PRB数是终端设备根据自身的硬件条件确定的,例如终端设备可以根据支持的最大终端传导功率和/或最大终端EIRP等信息确定该第二PRB数,进一步将该第二PRB数发送给网络设备。
作为示例二,终端设备可以向网络设备上报该终端设备的硬件条件,例如,支持的最大终端传导功率和/或最大终端等效全向辐射功率EIRP等信息发送给网络设备,进一步由网络设备确定该第二PRB数。
可选地,所述第一PRB数大于或等于所述第二PRB数。
在建立RRC连接后,如果终端设备的传输功率存在硬件条件限制,如最大发射功率UE_P=23dBm以及发送波束赋形增益Tx_BF=12dBi,计算达到硬件限制的带宽为
Figure PCTCN2021098322-appb-000006
以第一子载波间隔为120kHz为例,基于达到硬件条件限制的带宽,可以确定第二PRB数为BW/1.44=12个PRB。即可配置的PRB数上限从第一PRB数调整为第二PRB数,进一步地,终端设备将第二PRB数上报给网络设备,后续网络设备可以基于该第二PRB数确定目标PRB数。
在本申请一些实施例中,网络设备可以根据第二候选PRB数集合确定所述目标PRB数。
在一些实施例中,所述第二候选PRB数集合用于确定连接态的终端设备的PUCCH传输的目标 PRB数,换言之,所述第二候选PRB数集合用于确定连接阶段的PUCCH传输对应的目标PRB数。
在一些实施例中,所述第二候选PRB数集合中包括至少一个候选PRB数,所述至少一个候选PRB数中的每个候选PRB数均不超过第一PRB数。
在另一些实施例中,所述第二候选PRB数集合中包括至少一个候选PRB数,所述至少一个候选PRB数中的每个候选PRB数均不超过第二PRB数。
在一些实施例中,所述第二候选PRB数集合中的候选PRB数的粒度大于或等于一个PRB。
在一些实施例中,所述第二候选PRB数集合中的候选PRB数之间间隔的PRB数不等或相等。
应理解,在本申请实施例中,所述第二候选PRB数集合在网络设备和终端设备中可以以表格或列表等方式存储,本申请对于所述第二候选PRB数集合的存储方式不作限定。以下,以第二候选PRB数集合以表格方式存储为例进行说明,但本申请并不限于此。
在一些实施例中,所述第二候选PRB数集合中的每个候选PRB数对应一个索引,所述网络设备确定目标PRB数之后,可以向终端设备指示所述目标PRB数对应的索引,从而,终端设备可以根据所述索引查询所述第二候选PRB数集合对应的表格,将所述索引对应的候选PRB数确定为目标PRB数。
在一些实施例中,网络设备可以根据所述第二PRB数确定第二候选PRB数集合。
在一些实施例中,终端设备也可以根据第二PRB数确定第二候选PRB数集合,即网络设备和终端设备可以按照一致的方式确定所述第二候选PRB数集合,换言之,所述网络设备和终端设备对于所述第二候选PRB数集合中的候选PRB数的理解一致。
作为示例,若所述第二PRB数为12,则所述第二候选PRB数集合包括的候选PRB数可以如表3所示。

例如,网络设备首先根据预设规则,确定第一PRB数,进一步根据所述第一PRB数确定所述第二候选PRB数集合。
对应地,终端设备也可以根据预设规则,确定所述第二候选PRB数集合。例如,终端设备首先根据预设规则,确定第一PRB数,进一步根据所述第一PRB数确定所述第二候选PRB数集合。
作为示例,若根据预设规则确定第一PRB数为32,则所述第二候选PRB数集合包括的候选PRB数可以如表4所示。

在一些实施例中,网络设备可以基于终端设备的信道条件,从第二候选PRB数集合中为终端设备配置用于传输PUCCH的目标PRB数。例如,在终端设备的信道条件较优的情况下,在所述第二候选PRB数集合中选择较小的候选PRB数,在终端设备的信道条件较差的情况下,在所述第二候选PRB数集合中选择较大的候选PRB数,有利于保证上行传输的可靠性,同时在信道质量较优的情况下,采用较少的PRB数进行PUCCH传输,有利于实现更多UE的频分复用,提升频谱效率。因此,基于本申请实施例的目标PRB数的确定方式有利于提升上行传输的综合性能。
进一步地,网络设备向终端设备发送指示信息,所述指示信息用于指示用于连接态的终端设备的PUCCH传输所使用的PRB数,或者,所述指示信息用于指示连接态的PUCCH传输所使用的PRB数。例如,所述指示信息可以用于指示所述第二候选PRB数集合对应的表格中的PRB数索引,接收到该PRB数索引后,终端设备可以查询该第二候选PRB数集合对应的表格,获取该PRB数索引指示的候选PRB数,进一步将该候选PRB数作为用于PUCCH传输的目标PRB数。
可选地,所述指示信息可以通过高层信令发送,所述高层信令例如可以包括RRC信令。
结合图4,说明连接阶段的用于PUCCH传输的目标PRB数的确定方式。如图4所示,可以包括如下步骤:
S214,网络设备基于预设规则,确定第一PRB数;
S222,终端设备基于预设规则,确定第一PRB数。
应理解,本申请并不限定S214和S222的执行顺序。
S223,终端设备根据自身的硬件条件,调整用于PUCCH传输的PRB数上限,记为第二PRB数。
S224,终端设备向网络设备上报第二PRB数。
进一步地,S215,网络设备更新用于连接阶段PUCCH传输的PRB数上限,以及更新候选PRB数集合,将更新后的候选PRB数集合记为第二候选PRB数集合,例如,[1,…,N RB2],其中,N RB2表示第二PRB数。
S216,网络设备基于终端设备的信道条件,从第二候选PRB数集合中选择目标PRB数。
S217,网络设备向终端设备发送指示信息,所述指示信息用于指示所述目标PRB数。
在另一些实施例中,连接态的终端设备也可以不上报所述第二PRB数,或者,不上报终端设备的能力,此情况下,所述网络设备确定所述目标PRB数可以是根据所述第一PRB数确定的。
综合该实施例一,通过根据实施例一中的实现方式确定PUCCH传输对应的目标PRB数,有利于保证终端设备以最优的PRB数进行PUCCH传输,这里的最优的PRB数可以指考虑终端设备的信道条件下的最优PRB数,例如,在信道质量较优的情况下,通过较少的PRB数传输PUCCH,或者,在信道质量较差的情况下,通过较多的PRB数传输PUCCH,有利于兼顾PUCCH传输的可靠性和频谱效率,或者,也可以指在预设规则和/或终端设备的硬件条件限制下的最大PRB数,通过尽可能多的PRB数进行PUCCH传输,有利于提升PUCCH传输的覆盖性能。
实施例二
在本申请一些实施例中,所述终端设备确定PUCCH对应的目标PUCCH资源,包括:
所述终端设备根据所述目标PRB数N RB,确定传输所述PUCCH所使用的目标梳齿间隔M,其中,所述目标梳齿间隔M表示所述目标PUCCH资源中的相邻RE之间间隔的RE数。
因此,在本申请实施例中,在所述目标PRB数N RB个PRB资源上,可以使用每个PRB中的RE子集发送PUCCH,即可以采用子PRB(sub-PRB)梳齿映射模式发送PUCCH,有利于提升频谱效率。
在一些实施例中,若N RB小于12,将N RB个RE确定为所述目标梳齿间隔。
在另一些实施例中,若N RB等于12,将12个RE确定为所述目标梳齿间隔。
在又一些实施例中,若N RB大于12,将12个RE确定为所述目标梳齿间隔。
也就是说,当目标PRB数大于12时,可以采用固定的12个RE作为目标梳齿间隔,当目标PRB数小于或等于12时,目标梳齿间隔等于目标PRB数N RB,目标梳齿间隔的单位为RE。
在一些实施例中,若N RB小于12,所述目标PUCCH资源包括所述N RB个PRB上的12个RE。
在另一些实施例中,若N RB等于12,所述目标PUCCH资源包括12个PRB上的12个RE,其中,目标PUCCH资源在每个PRB中占一个RE。
在又一些实施例中,若N RB大于12,所述目标PUCCH资源包括N RB个RE。
在一些实施例中,若N RB小于12,并且N RB能够被12整除,则所述目标PUCCH资源中的每个PRB上包括的RE数相同,并且相邻的RE之间的间隔为N RB个RE。
在另一些实施例中,若N RB小于12,并且N RB不能够被12整除,则所述目标PUCCH资源中的PRB上包括的RE数不同,并且相邻的RE之间的间隔为N RB个RE。
在又一些实施例中,若N RB等于12,则所述目标PUCCH资源中的每个PRB上包括的RE数均为1,并且相邻的RE之间的间隔为12个RE。
在又一些实施例中,若N RB>12,则所述目标PUCCH资源中的每个PRB上包括的RE数均为1,并且N RB为6的倍数。
在本申请实施例中,将梳齿间隔为M(其中,1≤M≤12)个RE的sub-PRB梳齿映射模式记为comb-M。
在一些实施例中,当N RB≤12且能被12整除时,如N RB=1/2/3/4/6/12,目标PUCCH资源在N RB个PRB中的每个PRB上采用comb-1/2/3/4/6/12的sub-PRB梳尺映射模式。
图5示意了一个PRB上的comb-1/2/3/4/6/12的sub-PRB梳齿映射模式的示意图。如图5所示,对于comb-1的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为1个RE,对于comb-2的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为2个RE,对于comb-3的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为3个RE,对于comb-4的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为4个RE,对于comb-6的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为6个RE,对于comb-12的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为12个RE。
进一步地,在所述N RB个RPB中的每个PRB上,均基于所述sub-PRB梳齿映射模式确定PUCCH传输所占用的RE,或者说,所述目标PUCCH资源在N RB个RPB中的每个PRB内所占用的RE。
例如,如图6所示,对于comb-3的sub-PRB梳齿映射模式,目标PUCCH资源在3个PRB中的每个PRB(例如,RB#0,RB#1和RB#2)上均占用4个RE,相邻RE之间的间隔为3个RE。
因此,当N RB≤12且能被12整除时,目标PUCCH资源在N RB个PRB中的每个PRB上所映射的RE数相同。
在另一些实施例中,当N RB≤12且不能被12整除时,如N RB=5/7/8/9/10/11,目标PUCCH资源在N RB个PRB上采用comb-5/7/8/9/10/11的sub-PRB梳尺映射模式。
图7示意了一个PRB上的comb-5/7/8/9/10/11的sub-PRB梳齿映射模式的示意图。如图7所示,对于comb-5的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为5个RE,对于comb-7的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为7个RE,对于comb-8的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为8个RE,对于comb-9的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为9个RE,对于comb-10的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为10个RE,对于comb-11的sub-PRB梳齿映射模式,用于一个PUCCH传输的RE之间的间隔为11个RE。
在本申请实施例中,当N RB≤12,并且不能被12整除时,仍保证目标PUCCH资源占用的RE之间的间隔为N RB个RE,这种情况下,在该N RB个PRB中的每个PRB上所占的RE数不同。
以N RB等于5为例,如图8所示是在5个PRB上(例如,RB#0,RB#1,RB#2,RB#3,RB#4),目标PUCCH资源所占的RE位置示例。其中,在RB#0上占用3个RE,在RB#1上占用2个RE,在RB#2上占用3个RE,在RB#3上占用2个RE,在RB#4上占用2个RE,共占用12个RE,RE之间的间隔为5个RE。
因此,当N RB≤12且不能被12整除时,目标PUCCH资源在N RB个PRB中的PRB内所映射的RE数不同。
在又一些实施例中,所述N RB>12时,目标PUCCI资源在N RB个PRB中的每个PRB上采用comb-12的sub-PRB梳齿映射模式,此情况下,目标PUCCH资源占用的RE数和RB数相同,但占用的PRB数需要为6的倍数。即在N RB>12时,N RB mod 6=0。
因此,在该实施例二中,当终端设备确定用于传输PUCCH所使用的目标PRB数N RB后,即可确定用于传输PUCCH的目标梳尺间隔M。此时,在同一组PRB资源内,基于sub-PRB的梳齿映射模式,可以通过分配不同的梳尺索引实现频分复用,且频分复用能力等于该目标梳尺间隔M。应理解,这里的一组PRB资源指的是N RB个PRB。所述梳齿索引用于指示所述N RB个PRB中的一组RE,所述一组RE之间的间隔为所述目标梳齿间隔M,不同的梳齿索引对应的一组RE之间具有一定的RE偏移,例如,P个RE的偏移,所述P为小于等于M的正整数。
如图9所示,对于comb-3的sub-PRB梳齿映射模式,频分复用能力为3,即3个终端设备可以通过不同的梳齿索引复用同3个PRB资源中的不同的RE资源。例如,梳齿索引0、梳齿索引1和梳齿索引2分别用于指示3个PRB(RB#0~RB#2)中的每个PRB中的一组RE,其中,梳齿索引0对应的一组RE和梳齿索引1对应的一组RE具有一个RE的偏移,梳齿索引1的一组RE和梳齿索引2对应的一组RE具有一个RE的偏移,每个梳齿索引对应的一组RE均通过comb-3的梳齿映射模式映射得到。
因此,在本申请实施例中,基于上述sub-PRB梳齿映射模式,在同一组PRB资源内,可以实现RE级别的频分复用,此情况下,一个PUCCH传输所占用的PRB数为不使用sub-PRB梳齿时的1/M,提升了频谱效率。
综上,基于实施例一,可以确定目标PUCCH资源所占的PRB数,即所述目标PRB数,根据实施例二可以确定目标PUCCH资源在所占的目标PRB数内的映射方式,即在每个PRB数内所映射的RE位置,进一步地,结合实施例三,说明目标PUCCH资源的具体位置的确定方式,例如该目标PUCCH资源所占的PRB资源的具体位置,例如,起始PRB位置,以及目标PUCCH资源在每个PRB资源内对应的梳齿索引等信息。
实施例三
在本申请一些实施例中,所述S210包括:
所述终端设备确定目标PUCCH资源的起始PRB索引、目标PUCCH资源在所述N RB个PRB内占用的RE所对应的梳齿索引和所述目标PUCCH资源在码分复用时所使用的初始循环移位索引中的至少一项。
例如,对于初始接入阶段的PUCCH传输,终端设备可以首先确定目标PUCCH资源占用的PRB资源位置,即PUCCH传输所占用的PRB资源的位置,例如,起始PRB的位置,进一步再确定目标PUCCH资源在该N RB个PRB中对应的梳齿索引,即PUCCH传输在这一组PRB资源内对应的梳齿索引,即具体占用的RE位置。
在于本申请一些实施例中,终端设备可以根据N RB个PRB资源的频分复用能力M,结合码分复用能力N cs,确定N RB个PRB资源是否能够支持用于初始接入的一组PUCCH资源集合包括的PUCCH资源的总数K,进一步确定所述PUCCH传输对应的目标PUCCH资源的位置。
情况1:N RB个PRB资源能够支持用于初始接入的一组PUCCH资源集合包括的所有PUCCH资源。例如,M*N cs≥K。
此情况下,所述终端设备首先确定目标PUCCH资源对应的初始PRB索引。
例如,终端设备可以根据初始上行带宽部分BWP上的PRB偏移
Figure PCTCN2021098322-appb-000007
初始上行BWP包括的PRB数
Figure PCTCN2021098322-appb-000008
和N RB中的至少一项,确定所述目标PUCCH资源对应的起始PRB索引。
在一些实施例中,所述初始上行BWP上的PRB偏移
Figure PCTCN2021098322-appb-000009
可以为表1所示的取值。例如,0,2,3,4或
Figure PCTCN2021098322-appb-000010
等。
在一些实施例中,若PUCCH传输占用的正交频分复用(Orthogonal frequency-division multiplexing,OFDM)符号数大于或等于2,可以通过配置跳频以获取频率分集增益,即一次PUCCH传输在不同符号上占用的PRB位置是不同的。对于符号长度为L的PUCCH,如果被配置了跳频,则第1跳频单元的OFDM符号数为
Figure PCTCN2021098322-appb-000011
第2跳频单元的OFDM符号数为
Figure PCTCN2021098322-appb-000012
作为一个示例,所述终端设备确定所述目标PUCCH资源在第1跳频单元内对应的起始PRB索引为
Figure PCTCN2021098322-appb-000013
以及,确定所述目标PUCCH资源在第2跳频单元内对应的起始PRB索引为
Figure PCTCN2021098322-appb-000014
即PUCCH传输在第1跳频单元和第2跳频单元内占用的PRB索引是关于初始上行BWP对称分布的。
因此,本申请实施例通过根据PRB偏移
Figure PCTCN2021098322-appb-000015
设计PUCCH传输在跳频单元占用的PRB位置,以及基于对称性设计不同的跳频单元占用的PRB位置,有利于保证PUCCH传输在不同跳频单元内占用的PRB位置尽可能远,从而能够最大化通过跳频获得的频率分集增益。
如前所示,基于sub-PRB的梳尺映射方式可以实现多个PUCCH传输在一组PRB资源内进行RE级别的频分复用,因此,在本申请一些实施例中,在确定PUCCH传输对应的起始PRB索引后,还可以进一步确定PUCCH传输在这一组PRB资源内对应的梳齿索引。即所述目标PUCCH资源在所述 N RB个PRB内占用的RE所对应的梳齿索引。
例如,终端设备根据PUCCH传输对应的资源索引r PUCCH,目标梳齿间隔M和初始循环移位索引集合中的初始循环移位索引的个数N cs中的至少一项,确定所述目标PUCCH资源在所述N RB个PRB内占用的RE所对应的梳齿索引。
作为示例,所述终端设备根据如下公式确定所述目标PUCCH资源在所述N RB个PRB内占用的RE所对应的梳齿索引:
Figure PCTCN2021098322-appb-000016
其中,m表示所述梳齿索引,
Figure PCTCN2021098322-appb-000017
表示向下取整,mod表示取模。
终端设备确定所述目标PUCCH资源在所述N RB个PRB内对应的梳齿索引之后,即可确定所述目标PUCCH资源在所述N RB个PRB内所占用的RE位置。
进一步地,可以通过不同初始循环移位实现不同PUCCH传输在相同频域资源上的码分复用,引入初始循环移位实现不同PUCCH传输的码分复用,则在相同的频域资源的情况下,能够实现更多PUCCH传输的复用。因此,在本申请一些实施例中,所述终端设备还可以确定所述目标PUCCH资源在码分复用时所使用的初始循环移位索引。
在一些实施例中,终端设备可以根据PUCCH传输对应的资源索引r PUCCH和初始循环移位索引集合中的初始循环移位索引的个数N cs,确定所述目标PUCCH资源在码分复用时所使用的初始循环移位索引。
例如,所述终端设备根据如下公式确定目标PUCCH资源在码分复用时所使用的初始循环移位索引:
n cs=r PUCCH mod N cs
其中,n cs表示所述初始循环移位索引,mod表示取模。
在一些实施例中,所述r PUCCH根据如下公式确定:
Figure PCTCN2021098322-appb-000018
其中,N CCE表示终端设备接收到的下行调度信令所在的控制资源集合中的控制信道单元(Control Channel Element,CCE)的数量,n CCE,0表示终端设备接收到的下行调度信令的第一个CCE的索引,Δ PRI表示下行调度信令中的PUCCH资源指示字段所指示的值。
在一些实施例中,所述下行调度信令可以为下行控制信息(Downlink Control Information,DCI)。
在一些实施例中,网络设备可以通过系统消息为终端设备配置用于RRC连接建立前的一组PUCCH资源集合,其后,如果终端设备需要通过PUCCH反馈下行调度信令的混合自动请求重传-应答(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)信息,则可以通过r PUCCH确定发送PUCCH所使用的资源位置。
图10所示是根据本申请一个具体示例的PUCCH传输映射的资源位置示意图。
在图10的示例中,在初始接入阶段,r PUCCH∈{0,1,…,15},
Figure PCTCN2021098322-appb-000019
M=12,N cs=2,即频分复用能力为12和码分复用能力为2,即通过频分复用能力和码分复用能力能够支持24个PUCCH资源,即M*N cs>K,此情况下,通过一组PRB资源中的每个PRB中的8个RE和两个初始CS,即可支持用于初始接入的一组PCCH资源集合中的16个PUCCH资源,每个PUCCH资源可以用于一个PUCCH传输。
在频域,每个PUCCH资源可以占用一组PRB资源中的每个PRB中的一个RE,在码域,每个PUCCH资源可以使用两个初始CS中的一个。
如图10所示,基于前述的起始PRB索引的确定方式,可以确定每个PUCCH资源在第1跳频单元内对应的起始PRB索引均为0,以及,确定所述每个PUCCH资源在第2跳频单元内对应的起始PRB索引均为
Figure PCTCN2021098322-appb-000020
因此,基于初始接入阶段的16个PUCCH传输的跳频距离相同,且跳频增益最大。
应理解,在图10中,r PUCCH=0和1对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=2和3对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=4和5对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=6和7对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=8和9对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=10和11对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=12和13对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=14和15对应的PUCCH传输通过码分方式复用在相同的RE上。
情况2:N RB个PRB资源不能够支持用于初始接入的一组PUCCH资源集合包括的所有PUCCH资源。例如M*N cs<K。也就是说,需要多组PRB资源(即多组N RB个PRB)才能够支持用于初始接入的一组PUCCH资源集合包括的所有PUCCH资源。
此情况下,所述终端设备首先确定目标PUCCH资源对应的初始PRB索引。
例如,所述终端设备根据所述PUCCH传输对应的资源索引r PUCCH、初始上行BWP上的PRB偏移
Figure PCTCN2021098322-appb-000021
初始上行BWP包括的RB数
Figure PCTCN2021098322-appb-000022
和上行BWP包括的RE数N RB中的至少一项,确定所述目标PUCCH资源对应的起始PRB索引。
在一些实施例中,所述初始上行BWP上的PRB偏移
Figure PCTCN2021098322-appb-000023
为表1所示的取值。例如,0,2,3,4或
Figure PCTCN2021098322-appb-000024
等。
在该情况2中,基于每组PRB资源的频分复用能力M,以及码分复用能力N cs,每组N RB个PRB仍支持M*N cs个用户的复用,但是M*N cs<K,因此,需要多组PRB资源才能支持K个PUCCH资源。
以K个PUCCH资源为16个PUCCH资源为例,说明r PUCCH对应的PUCCH传输的起始PRB索引的确定方式,或者说,目标PUCCH资源对应的起始PRB索引的确定方式。作为一个示例,若
Figure PCTCN2021098322-appb-000025
确定r PUCCH对应的PUCCH传输在第1跳频单元内对应的起始PRB索引为
Figure PCTCN2021098322-appb-000026
以及确定r PUCCH对应的PUCCH传输在第2跳频单元内对应的起始PRB索引为
Figure PCTCN2021098322-appb-000027
即PUCCH传输在第1跳频单元和第2跳频单元内占用的PRB索引是关于初始上行BWP对称分布的。
作为一个示例,若
Figure PCTCN2021098322-appb-000028
确定r PUCCH对应的PUCCH传输在第1跳频单元内对应的起始PRB索引
Figure PCTCN2021098322-appb-000029
以及确定r PUCCH对应的PUCCH传输在第2跳频单元内对应的起始PRB索引为
Figure PCTCN2021098322-appb-000030
即PUCCH传输在第1跳频单元和第2跳频单元内占用的PRB索引是关于初始上行BWP对称分布的。
其中,
Figure PCTCN2021098322-appb-000031
表示向下取整,r PUCCH的确定方式参考情况1中的相关说明,为了简洁,这里不再赘述。
因此,在本申请实施例中,通过将16个PUCCH资源或者说16个PUCCH传输分成两组,即r PUCCH∈{0,1,…,7}对应的PUCCH传输,以及r PUCCH∈{8,9,…,15}对应的PUCCH传输,分别在初始上行BWP对应的PRB位置的两端为这两组PUCCH传输分配对应的PRB位置,以及对于每个PUCCH传输,通过对称设计该PUCCH传输在第1跳频单元和第2跳频单元内占用的PRB索引,能够最大化通过跳频获得的频率分集增益。
如前所示,基于sub-PRB的梳尺映射方式可以实现多个PUCCH传输在一组PRB资源内进行RE级别的频分复用,因此,在本申请一些实施例中,在确定PUCCH传输对应的起始PRB索引后,所述终端设备还可以进一步确定PUCCH传输在N RB个PRB资源内对应的梳齿索引。即所述目标PUCCH资源在所述N RB个PRB内占用的RE所对应的梳齿索引。
例如,所述终端设备根据PUCCH传输对应的资源索引r PUCCH,目标梳齿间隔M和初始循环移位索引集合中的初始循环移位索引的个数N cs中的至少一项,确定所述目标PUCCH资源在所述N RB个个PRB内占用的RE所对应的梳齿索引。
作为示例,所述终端设备根据如下公式确定所述目标PUCCH资源在所述N RB个个PRB内占用的RE所对应的梳齿索引:

其中,m表示所述梳齿索引,
Figure PCTCN2021098322-appb-000033
表示向下取整,mod表示取模。
终端设备确定所述目标PUCCH资源在所述N RB个PRB内对应的梳齿索引之后,即可确定所述目标PUCCH资源在所述N RB个PRB内所占用的RE位置。
进一步地,可以通过不同初始循环移位实现不同PUCCH传输在相同频域资源上的码分复用,引入初始循环移位实现不同PUCCH传输的码分复用,则在相同的频域资源的情况下,能够实现更多PUCCH传输的复用。因此,在本申请一些实施例中,所述终端设备还可以确定所述目标PUCCH资源在码分复用时所使用的初始循环移位索引。
例如,所述终端设备根据PUCCH传输对应的资源索引r PUCCH和初始循环移位索引集合中的初始循环移位索引的个数N cs中的至少一项,确定所述目标PUCCH资源在码分复用时所使用的初始循环移位索引。
作为示例,所述终端设备根据如下公式确定目标PUCCH资源在码分复用时所使用的初始循环移位索引:
n cs=r PUCCH mod N cs
其中,n cs表示所述初始循环移位索引,mod表示取模。
图11所示是根据本申请一个具体示例的PUCCH传输映射的资源位置示意图。
在图11的示例中,
Figure PCTCN2021098322-appb-000034
M=4,N cs=2,即频分复用能力为4和码分复用能力为2,即通过频分复用能力和码分复用能力仅能够支持8个PUCCH资源,即M*N cs<K,此情况下,通过两组PRB资源中的每个PRB中的RE资源和两个初始CS,可以支持用于初始接入的一组PCCH资源集合中的16个PUCCH资源,每个PUCCH资源可以用于一个PUCCH传输。
在r PUCCH∈{0,1,…,7}时,r PUCCH对应的PUCCH传输在第1跳占用RB#0~3,在第2跳占用
Figure PCTCN2021098322-appb-000035
在r PUCCH∈{8,9,…,15}时,r PUCCH对应的PUCCH传输在第1跳占用
Figure PCTCN2021098322-appb-000036
在第2跳占用RB#0~3。此情况下,仍能保证初始接入阶段的16个PUCCH传输的跳频距离相同,且跳频增益最大。
应理解,在图11中,r PUCCH=0和1对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=2和3对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=4和5对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=6和7对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=8和9对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=10和11对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=12和13对应的PUCCH传输通过码分方式复用在相同的RE上,r PUCCH=14和15对应的PUCCH传输通过码分方式复用在相同的RE上。
应理解,在实施例三中,所述目标PUCCH资源可以为用于非连接态的终端设备的公共PUCCH资源。
综合该实施例三,终端设备通过确定PUCCH资源的起始PRB索引,以及基于sub-PRB梳齿映射方式确定PUCCH资源在每个PRB内所占用的RE,在实现PUCCH在多个PRB上的传输的同时,还能够最大化跳频增益。

所述目标PUCCH资源在所述目标PRB数个PRB内占用的RE所对应的梳齿索引m和所述目标PRB数N RB中的至少一项。
例如,终端设备可以根据所述目标PRB数N RB,确定目标梳齿间隔,具体确定方式参考实施例 二的相关描述。
又例如,所述终端设备可以根据所述目标PRB数N RB确定PUCCH传输所占用的RE数。例如,若N RB小于或等于12,PUCCH传输在一组PRB资源中占用12个RE,若N RB大于12,PUCCH传输在一组PRB资源中占用N RB个RE,并且N RB为6的倍数。
在本申请实施例中,网络设备可以通过给不同的终端设备指示不同的梳齿索引m实现多UE的频分复用,并且不会发生资源冲突。例如,网络设备可以在不同的终端设备的梳齿间隔的最大公约数大于1的情况下,通过不同的梳齿索引实现多UE的频分复用。
例如,对于相同梳齿间隔的UE复用,网络设备可以通过给UE配置不同的梳齿索引实现多UE的频分复用。
以实现UE-1和UE-2的频分复用为例说明,其中,网络设备给UE-1指示的PUCCH资源配置为:
Figure PCTCN2021098322-appb-000038
N RB=12和m=0,网络设备给UE-2指示的PUCCH资源配置为:
Figure PCTCN2021098322-appb-000039
N RB=12和m=6。则UE-1在12个PRB(RB#0~RB#11)上采用comb-12的梳齿映射模式,UE-2在12个PRB(RB#0~RB#11)上也采用comb-12的梳齿映射模式。
UE的PUCCH传输占用的RE索引可以表示为

其中0≤i≤N RE

表示一个RB上的子载波数,该
Figure PCTCN2021098322-appb-000042

将网络设备对UE-1的PUCCH资源配置代入上式,可得UE-1的PUCCH传输占用的RE索引为:
Figure PCTCN2021098322-appb-000043
其中0≤i≤12。将网络设备对UE-2的PUCCH资源配置代入上式,可得UE-2的PUCCH传输占用的RE索引为:
Figure PCTCN2021098322-appb-000044
其中0≤i≤12。
即,UE-1的PUCCH传输在12个PRB中的每个PRB上均占用RE 0,UE-2的PUCCH传输在12个PRB中的每个PRB上均占用RE 6,因此,UE-1和UE-2即使使用同一组PRB资源,网络设备通过配置不同的梳齿索引,也可以避免UE之间的资源冲突,图12所示是UE-1和UE-2的PUCCH传输对应的PUCCH资源的示意性图。
又例如,当UE的梳齿间隔不同,但是UE的梳齿间隔的最大公约数大于1时,网络设备也可以通过配置不同的梳齿索引实现多UE的频分复用。
以实现UE-1和UE-2的频分复用为例说明,其中,网络设备给UE-1指示的PUCCH资源配置为:

N RB=4和m=0,网络设备给UE-2指示的PUCCH资源配置为:
Figure PCTCN2021098322-appb-000046
N RB=6和m=1。则UE-1在4个PRB(RB#0~RB#11)上采用comb-4的梳齿映射模式,UE-2在6个PRB(RB#0~RB#11)上采用comb-6的梳齿映射模式。
UE的PUCCH传输占用的RE索引可以表示为

其中0≤i≤12。
图13所示是UE-1和UE-2的PUCCH传输对应的PUCCH资源的示意性图,从图13可以看出,UE-1和UE-2即使使用同一组PRB资源,网络设备通过配置不同的梳齿索引,也可以避免UE之间的资源冲突。
进一步,若存在UE-3,网络设备给UE-3指示的PUCCH资源配置为:
Figure PCTCN2021098322-appb-000052
N RB=2和m=0,基于上述公式,计算可得UE-3的PUCCH传输占用的RE索引为:

其中0≤i≤12。
图14所示是UE-1、UE-2和UE-3的PUCCH传输对应的PUCCH资源的示意性图,从图14可以看出,UE-1、UE-2和UE-3即使使用同一组PRB资源,网络设备通过配置不同的梳齿索引m、
Figure PCTCN2021098322-appb-000054
和N RB中的至少一项,也可以实现多UE的频分复用。
因此,在本申请实施例中,网络设备可以通过给终端设备配置不同的起始PRB索引
Figure PCTCN2021098322-appb-000055
不同的梳齿索引m或不同的PRB数N RB,从而能够使得不同的终端设备在同一组PRB资源中的频分复用,提升频谱效率。
综合该实施例四,基于sub-PRB的梳齿映射方式可以实现多UE的频分复用,例如可以实现不同PRB数的UE在频域的灵活复用。
需要说明的是,上述实施例一至实施例四可以单独实施,或者也可以结合实施,本申请实施例对此不作限定。
综合上述实施例,终端设备可以确定PUCCH传输所使用的目标PRB数,进一步可以确定基于该目标PRB数进行所述PUCCH传输所采用的梳齿映射方式,即以多大的梳齿间隔传输PUCCH,在初始接入阶段,终端设备还可以确定PUCCH传输对应的起始PRB索引,PUCCH传输在目标PRB数个PRB中的梳齿索引以及PUCCH传输所使用的初始循环移位索引,或者进入连接阶段之后,终端设备可以基于网络设备的指示确定PUCCH传输所使用的的目标PRB数,PUCCH传输对应的起始PRB索引,PUCCH传输在目标PRB数个PRB中的梳齿索引等信息,基于sub-PRB的梳齿映射方式进行PUCCH传输,有利于实现多UE的频分复用,提升频谱效率,并且通过实现PUCCH在多个PRB上的传输,有利于提升上行传输覆盖性能。
