图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User  Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面对本申请实施例中出现的名词作出如下解释:
1.PUCCH
PUCCH,可以用于终端向基站发送与上行调度相关的信息,如调度请求SR(Scheduling Request)、HARQ反馈,以及信道状况信息(Channel Status Information,CSI)。
2.PRB
PRB为:在NR通信系统中,频域上连续的12个RE。
3.子载波间隔(Subcarrier Spacing,SCS)
子载波间隔为频域上的最小的粒度。例如,在NR通信系统中,15×2 n,n为大于等于0的整数,一个子载波宽度可以为15kHz、30kHz和60kHz中的一种,但不限于上述列举的3个子载波宽度。
4.PUCCH的格式
在NR通信系统中的PUCCH支持5种不同的格式,按照时域上所占用的符号数量可以分为短格式和长格式两种,短格式占用1-2个符号,长格式占用4-14个符号,如下表1所示:
表1
Figure PCTCN2021142875-appb-000001
5.PUCCH的序列生成
PUCCH格式0序列为长为12的计算机序列(Computer Generated Sequence,CGS),均峰比(Peak to Average Power Ratio,PAPR)较低、具有单载波特性。在格式0的情 况下,其循环移位的大小由初始的循环移位和混合自动重传请求确认(Hybrid automatic repeat request acknowledgement,HARQ-ACK)特定的循环移位共同确定。通过序列的选择承载UCI信息,即通过序列的不同循环移位表示不同的信息。不同循环移位的序列之间是正交的,所以多个UE可以选择各自的循环移位,且复用同一个资源块(Resource Block,RB)。
PUCCH格式1序列为长为12的CGS序列,其不需要通过序列的循环移位来承载信息,序列的循环移位仅用于多用户的码分复用。PUCCH格式1要使用序列来承载1bit或2bit信息的方式为:通过把要承载的信息的调制符号与序列相乘来承载到序列上。当需要承载1bit信息时,用二进制相移键控(Binary Phase Shift Keying,BPSK)调制,当需要承载2bit信息时,用正交相移键控(Quadrature Phase Shift Keying,QPSK)调制,然后将调制符号与序列相乘,形成长为12的调制序列。
PUCCH格式3序列为长为12的CGS序列,在PUCCH格式1中,由于PUCCH格式2要承载的上行控制信息(Uplink Control Information,UCI)信息较多,所以无法采用序列循环移位的不同来承载信息的方法,只能使用UCI+解调参考信号(Demodulation Reference Signal,DMRS)的传输方式。经过信道编码的bit序列经过加扰、调制后映射到资源要素(Resource Element,RE)上。PUCCH格式2的UCI信息不进行离散傅立叶变换(Discrete Fourier Transform,DFT)预编码,也就是说采用CP-OFDM波形,且调制方式固定采用QPSK,不采用pi/2-BPSK。
PUCCH格式3序列为长为12的CGS序列,PUCCH格式3采用DFT-s-OFDM波形,为了进一步降低PAPR,引入了pi/2-BPSK,具体采用pi/2-BPSK还是QPSK由高层参数指示。PUCCH格式3也不采用序列循环移位承载信息的方式,信道编码后的bit序列经过加扰、调制和DFT预编码后映射到RE。
PUCCH格式3序列为长为12的CGS序列,PUCCH格式4支持码分复用,即可以多用户复用。UCI通过扩频来支持多用户复用,所以调制后序列要经过扩频处理以支持码分复用,即经过信道编码的bit序列要经过加扰、调制、块式扩频(Block-wise Spreading)和DFT预编码之后,映射到资源。而DMRS是通过序列的循环移位来实现多用户复用,所以UCI扩频时的正交序列与DMRS的循环移位之间存在预定义的关系。
6.PUCCH的序列映射
PUCCH格式0在时域上占用1或2个符号,在频域上占1个RB的全部12个子载波,没有DMRS。因此生成的长度为12的序列直接映射到PRB的12个RE上。
PUCCH格式1在时域占用4-14个符号,频域占用12个子载波,是长格式PUCCH,可以配置slot内跳频,跳频时第一hop内的符号数量是总符号数量除以2并向下取整,剩下的符号在第二hop内。对于资源映射,在UCI和DMRS映射到RE时,PUCCH格式1的UCI和DMRS间隔放置,占用的符号尽可能均分,也就是说无论是否配置了跳频,DMRS只占用PUCCH中偶数索引的OFDM符号(以第一个符号索引为0开始)。
PUCCH格式2的DMRS生成公式与CP-OFDM波形的PUSCH的DMRS相同,DMRS与UCI为频分复用的方式,这个与PUCCH格式1不同。PUCCH格式2频域上占用1-16个RB中的任意值,DMRS密度为3,即一个RB内有3个RE由DMRS占用,其余RE为UCI。时域上占用1或2个符号,为短PUCCH。
PUCCH格式3时域占用4-14个符号,频域占用1-16个RB中取值为2、3、5的幂次方的乘积的RB数量的子载波(这个设定是基于DFT预编码运算效率考虑),为长PUCCH,DMRS与UCI为时分复用,各自占用RB内的全部子载波,这个与PUCCH格式1类似。
PUCCH格式4频域占用1个RB的全部12个子载波,时域与格式3相同,为4-14个符号,是长格式PUCCH,同样DMRS与UCI为时分复用,且DMRS的位置配置与格式3相同。

Figure PCTCN2021142875-appb-000002
7.PUCCH频域资源的配置
PUCCH资源包括公用的资源配置(小区级配置)和专用的资源配置(UE级配置),公用的资源配置根据上述表2和RRC的信令得到频域资源的配置,RRC的信令可以指定表2中的某一行,再根据检测的下行链路控制信息(Downlink Control Information,DCI)的控制信道单元(Control Channel Element,CCE)及携带的PUCCH资源指示信令,以及PRB offset,BWP的PRB大小得到PRB的起始位置。由于公共资源配置里只能有PUCCH格式0和1,即频域资源大小都是为1个PRB,则指定PRB起始位置后,就可以得到频域资源的位置。
专用的频域资源配置通过RRC确定第一个跳频(或没有跳频时)的起始PRB,second Hop PRB确定第二个跳频的起始PRB,对于只有一个PRB的格式0,格式1,格式4才能够确定频域资源位置。
现有的NR通信系统在60GHz频带下,由前述内容可知,用于承载上行控制信息的PUCCH在格式0、格式1和格式4的频域资源固定为1个PRB,而在频域资源为单个PRB的情况下,根据相关协议规定,在60GHz频带上的最大PSD为23dBm/MHz,远远小于对最大的射频输出功率,即40dBm,因此,在PSD的限制下,会限制UE发送信号的功率,进而导致UE发送的信号覆盖范围较小,覆盖情况较差(例如,UE发送的信号的覆盖范围面积小)。
在本申请实施例提供的资源映射方法中,UE采用了N个目标PRB作为PUCCH的频域资源(N为大于1的正整数),在此基础上,UE确定上述N个目标PRB的位置信息,并根据上述位置信息,将上述目标PUCCH的序列信息映射至上述N个目标PRB上。如此,当通信系统处于60GHz频带的情况下,由于UE用于支持PUCCH的频域资源为多个PRB,因此,会增大UE发送信号的功率,进而增大SNR,最终可以 改善UE发送的信号覆盖情况,增大覆盖范围。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的资源映射方法进行详细地说明。
图2示出了本申请实施例提供的一种资源映射方法的流程示意图,如图2所示,应用于UE,该资源映射方法可以包括步骤201和步骤202:
步骤201:UE确定N个目标物理资源块PRB的位置信息。
在本申请实施例中,上述N个目标PRB为上述目标物理上行链路控制信道PUCCH的频域资源,N为大于1的正整数。
在本申请实施例中,上述N个目标PRB的数目大于1。
可以理解的,由前述介绍的内容可知,在PUCCH格式为格式0、格式1和格式4的情况下,频域资源为上的PRB为1,则在这三种PUCCH格式下,UE会通过使用多个PRB增大UE发送信号的功率,从而增大PUCCH的覆盖范围。
在本申请实施例中,上述位置信息可以为N个目标PRB在其所处频域资源的绝对位置信息。
步骤202:UE根据上述位置信息,将上述目标PUCCH的序列信息映射至上述N个目标PRB上。
需要说明的是,本申请实施例不限于应用于60GHz频带,也可以适用于其他频率范围。
在本申请实施例提供的资源映射方法中,UE先行确定目标物理上行链路控制信道PUCCH的频域资源,即N个目标物理资源块PRB的位置信息PUCCH的位置信息,N为大于1的正整数,然后根据N个目标PRB的位置信息,将上述目标PUCCH的序列信息映射至上述N个目标PRB上,N为大于1的正整数。如此,由于UE用于支持PUCCH的频域资源为多个PRB,因此,会增大UE发送信号的功率,进而增大SNR,最终可以改善UE发送的信号覆盖情况,增大覆盖范围。
可选的,在本申请实施例中,在上述步骤201中,本申请实施例提供的资源映射方法可以包括如下步骤203和步骤204:
步骤203:UE确定M个第一PRB的第一索引信息。
示例性的,上述第一索引信息用于指示上述M个第一PRB的位置信息。
示例性的,上述M个第一PRB为所述N个目标PRB中的M个PRB,M为小于或等于N正整数。
步骤204:UE根据上述第一索引信息确定N个目标PRB的位置信息。
示例性的,上述第一索引信息还可以包括M个第一PRB的索引。
可选的,在本申请实施例中,上述第一索引信息为预定义的,或者,协议规定的,或者,预配置的。
示例性的,上述M和N之间的关系分为如下两种情况:
第一种情况:当上述M等于N时,上述第一索引信息可以包含N个目标PRB的索引信息。其中,上述N个目标PRB的索引信息中,包含每个目标PRB在频域资源的绝对位置信息。
第二种情况:当上述M小于N时,上述第一索引信息可以包含M个第一PRB的索引信息。其中,上述M个第一PRB的索引信息中,包含每个第一PRB在上述目标PUCCH的相对位置信息和每个第一PRB在频域资源中的绝对位置信息,进一步的,可以将上述M个第一PRB的索引信息中的索引作为参考PRB的索引(也即,M个第一PRB为参考PRB)。根据参考PRB的索引,剩余N-M个目标PRB通过数目信息、和/或相对位置信息、和/或M个参考PRB中至少一个PRB在PUCCH的频域资源中的相对位置信息,即可得出剩余N-M个目标PRB的索引信息。具体的实施方案在后续内容中进行描述。
需要说明的是,上述步骤203和步骤204的技术方案既可在目标PUCCH的频域资源为专用的PUCCH资源的情况下应用,也可以在目标PUCCH的频域资源为公用的PUCCH资源的情况下应用。
如此,UE通过M个第一PRB的用于指示该第一PRB的位置信息的第一索引信息,即可确定N个目标PRB的位置信息,M为小于或者等于N的正整数。如此,无 论UE获取所有PRB的索引信息还是仅获取部分目标PRB的索引信息,最终均可确定所有目标PRB的位置信息,从而方便UE在不同场景下确定N个目标PRB的位置信息。
可选的,在本申请实施例中,在上述步骤201之前,本申请实施例提供的资源映射方法可以包括如下步骤205:
步骤205:从网络侧设备接收目标信息。
示例性的,上述目标信息用于确定上述N个目标PRB的位置信息;上述目标信息包括X个SCS对应的SCS信息;上述X个SCS对应的SCS信息包括:每个SCS对应的索引信息;上述第一索引信息为:所述X个SCS中所述UE所处的目标SCS对应的索引信息。
示例性的,上述第一索引信息可以参照前述描述,此处不再赘述。
示例性的,上述SCS信息可以参照前述描述,此处不再赘述。
示例性的,上述目标SCS为X个SCS中的一个。例如,当X个SCS为3个SCS,分别为15kHz、30kHz和60kHz时,若UE侧当前处所的SCS为15kHz,则目标SCS即为15kHz。
如此,当UE处于不同SCS的情况下,由于接收到来自网络侧的不同SCS对应的N个目标PRB的索引信息,因此,UE可以获取到当前PUCCH的SCS的N个目标PRB的索引信息,以便于准确、快捷的确定N个目标PRB的索引信息,进而完成目标PUCCH的序列信息在N个目标PRB上的映射。
可选的,在本申请实施例中,上述第一索引信息包括:第一索引集合。
示例性的,上述第一索引集合包括上述M个第一PRB的索引。
在一种示例中,当上述M=N时,上述第一索引集合可以包含N个目标PRB的索引信息的索引集合。也即,在上述M=N的情况下,UE通过第一索引集合可以直接获取含N个目标PRB的索引信息。
在另一种示例中,当M<N时,上述第一索引集合可以包含M个第一PRB的索引信息的索引集合,也即,在上述M<N的情况下,UE通过第一索引集合可以获取含M个第一PRB的索引信息。进一步的,可以将上述M个第一PRB的索引信息中的索引作为参考PRB的索引(也即,M个第一PRB为参考PRB)。根据参考PRB的索引,剩余N-M个目标PRB通过数目信息、和/或相对位置信息、和/或M个参考PRB中至少一个PRB在PUCCH的相对位置信息,即可得出剩余N-M个目标PRB的索引信息。
需要说明的是,上述第一索引集合对应的技术方案既可在目标PUCCH的频域资源为专用的PUCCH资源的情况下应用,也可以在目标PUCCH的频域资源为公用的PUCCH资源的情况下应用。
如此,UE可以通过第一索引集合直接获取M个第一PRB的索引信息,并根据M的大小,可以直接获取N个目标PRB的索引信息,或者获取M个参考PRB的索引信息,进而获取剩余PRB的索引信息。如此,无论UE获取所有PRB的索引信息还是仅获取部分目标PRB的索引信息,最终均可确定所有目标PRB的位置信息,从而使得UE在获知部分或全部的PRB索引信息这两种场景下,均能够准确确定N个目标PRB的位置信息。
可选的,在M小于N的情况下,在上述步骤201之后,本申请实施例提供的资源映射方法可以包括如下步骤206:
步骤206:UE根据上述第一索引信息,确定至少一个第二PRB的位置信息。
示例性的,上述至少一个第二PRB为:上述N个目标PRB中除所述M个PRB以外的其他PRB。
可选的,在上述目标PUCCH的频域资源为专用的PUCCH资源的情况下,上述步骤206中,本申请实施例提供的资源映射方法可以包括如下步骤206a:
步骤206a:UE根据上述第一索引信息和第一信息,确定至少一个第二PRB的第二索引信息。
示例性的,上述第一信息包括以下任一项:

在上述UE无法获知上述N个目标PRB对应索引是否为连续索引的情况下,上述N个目标PRB对应的目标图样信息和至少一个第一PRB在上述目标PUCCH的相对位置信息;
上述第二索引信息用于指示每个上述第二PRB的位置信息。
示例性的,上述目标图样信息为多个图样信息中的一个。其中,图样信息可以用于确定PUCCH上的PRB的数量和不同PRB之间的相对位置情况。例如,当目标图样信息为{111111000000}时,该图样信息表明PUCCH上的PRB的数量为6,当PRB的第一索引信息为K1时且第一PRB在PUCCH中的相对位置为最小索引,则PRB的相对位置情况为{K1,K1+1,K1+2,K1+3,K1+4,K1+5}(目标图样信息中的1表示有PRB资源,0代表没有PRB资源)
可选的,在本申请实施例中,上述目标图样信息为:RRC配置或协议规定的或预定义的至少一个预设图样信息中的一个预设图样信息。
可选的,在本申请实施例中,上述目标PRB的数量为:RRC配置或协议规定的或预定义的。
可选的,在本申请实施例中,上述每个上述第二PRB与至少一个第一PRB间的相对位置信息为:RRC配置或协议规定的或预定义的。
可选的,在本申请实施例中,上述至少一个第一PRB在上述目标PUCCH的相对位置信息为:RRC配置或协议规定的或预定义的。

2.上述或协议规定的可以为:在PUCCH中包含多个PRB、且UE获知了其中部分PRB的情况下,相关技术中的协议(例如、NR通信系统下的预定协议)所规定的第二PRB的目标图样信息、或者目标PRB的数量、或者每个上述第二PRB与至少一个第一PRB间的相对位置信息、或者至少一个第一PRB在上述目标PUCCH的相对位置信息。
3.上述预定义的可以为:在PUCCH中包含多个PRB、且UE获知了其中部分PRB的情况下,UE中提前预设置的在满足相关条件的情况下,第二PRB的目标图样信息、或者目标PRB的数量、或者每个上述第二PRB与至少一个第一PRB间的相对位置信息、或者至少一个第一PRB在上述目标PUCCH的相对位置信息。
示例性的,在上述N个目标PRB对应索引为连续索引的情况下,UE即可获知上述N个目标PRB为连续的PRB,在此基础上,当UE获取到M个第一PRB的索引信息,以及目标PRB的数量和至少一个第一PRB在上述目标PUCCH的频域资源中的相对位置信息(即上述第一信息)时,既可获知第二PRB的位置信息,进而获得N个目标PRB在其所处频域资源的绝对位置的位置信息。
例1,在UE获知N个目标PRB为连续的PRB且获取了N个目标PRB中的一个PRB(第一PRB)的索引信息的情况下,目标PRB在获取到N=5以及第一PRB的在上述目标PUCCH的相对位置信息时,既可获知除第一PRB以外其他4个PRB(即上述第二PRB)的索引信息,最终获取上述5个PRB在其所处频域资源的绝对位置的位置信息。
需要说明的是,上述连续信息为UE根据NR通信系统下的预定协议获取的。
示例性的,在上述UE无法获知上述N个目标PRB对应索引是否为连续索引的情况下,在UE获取到M个第一PRB的索引信息的基础上:
若UE获取到每个上述第二PRB与至少一个第一PRB间的相对位置信息时,既可获知第二PRB的位置信息,进而获得N个目标PRB在其所处频域资源的绝对位置的位置信息。
例2:在UE获取了N个目标PRB中的一个PRB(第一PRB)的索引信息的情况下,目标PRB在获取到4个第二PRB与上述第一PRB的相对位置信息的情况下,既可获知除第一PRB以外其他4个PRB(即上述第二PRB)的索引信息,最终获取上述5个PRB在其所处频域资源的绝对位置的位置信息。
若UE获取到上述N个目标PRB对应的目标图样信息和至少一个第一PRB在上述目标PUCCH的频域资源中的相对位置信息的情况下,既可获知第二PRB的位置信息,进而获得N个目标PRB在其所处频域资源的绝对位置的位置信息。
例3:在UE获取了N个目标PRB中的一个PRB(第一PRB)的索引信息的情况下,目标PRB在获取到目标图样信息,且该目标图样信息显示PUCCH上具有5个PRB,以及上述第一PRB在PUCCH的频域资源中的相对位置信息的情况下,既可获知除第一PRB以外其他4个PRB的索引信息(即上述第二PRB)的索引信息,最终获取上述5个PRB在其所处频域资源的绝对位置的位置信息。
示例1:上述目标PUCCH的频域资源为专用的PUCCH资源,在上述第一信息包括上述N个目标PRB对应的目标图样信息和至少一个第一PRB在上述目标PUCCH的频域资源中的相对位置信息的情况下,UE在接收到网络侧设备的RRC配置一个第一PRB的索引信息(即上述第一索引信息),其中,该索引信息针对N个目标PRB的格式均为:第一PRB的索引为K1,并且确定了上述第一PRB的在PUCCH的频域资源中为最小PRB(即上述至少一个第一PRB在上述目标PUCCH的频域资源中的相对位置信息)。
在此基础上,通信系统可以与4组图样信息相对应,分别为{111111111111}、{111111000000}、{000000111111}、{110011001100},其中1代表该位置处有PRB资源,0代表没有PRB资源,UE依据接收到的网络侧设备的RRC指示,确定目标图样信息为{111111000000},进而将目标图样信息与第一PRB的索引信息以及第一PRB的在PUCCH的频域资源中为最小PRB的信息结合,确定了N个目标PRB的位置信息为{K1,K1+1,K1+2,K1+3,K1+4,K1+5}。
如此,在上述目标PUCCH的频域资源为专用的PUCCH资源,且UE获取了第一PRB(即部分PRB)的索引信息的情况下,可以通过上述多种不同的方式获取所有PRB在其所处频域资源的绝对位置的位置信息。
可选的,在本申请实施例中,在上述步骤201之前,本申请实施例提供的资源映射方法可以包括如下步骤207:

在一种示例中,上述每个SCS对应的图样信息,即为当UE处于不同的SCS下,N个目标PRB的对应的图样信息的图样信息集合。例如:第一位置信息可以包括,在UE所处的SCS为15KHz的情况下,N个目标PRB的图样信息,以及在UE所处的SCS为30KHz的情况下,N个目标PRB的图样信息。
如此,当UE处于不同SCS的情况下,由于接收到来自网络侧的不同SCS对应的N个目标PRB的位置信息或图样信息,因此,UE可以获取到符合当前所处的SCS的N个目标PRB的位置信息和图样信息,以便于准确、快捷的确定N个目标PRB的位 置信息,进而完成目标PUCCH的序列信息在N个目标PRB上的映射。
可选的,在上述目标PUCCH的频域资源为公用的频域资源的情况下,在上述步骤201中,本申请实施例提供的资源映射方法可以包括如下步骤208:

需要说明的是,一个PRB的RE个数通常为12。
示例性的,在上述目标PUCCH的序列信息的序列长度与上述N个目标PRB的RE数目相等的情况下:
在一种示例中,在上述目标PUCCH的序列信息的序列长度与上述N个目标PRB的RE数目相等的情况下,预设方式为按照上述序列信息的序列长度,将上述序列信息一一映射在上述N个目标PRB的RE上可以为:目标PUCCH的序列长度与N个目标PRB的总RE个数相同。
例4:在上述目标PUCCH的序列信息的序列长度为12*N,且目标PRB的个数为N(也即RE的个数为12*N)的情况下,可以将目标PUCCH的序列信息一一映射至PRB上。
示例性的,在上述目标PUCCH的序列信息的序列长度和每个目标PRB的RE数目相等的情况下:
在一种示例中,预设方式为在上述N个目标PRB上重复映射,也即将上述目标PUCCH的序列信息在每个目标PRB上均进行一次映射。
例2:在上述目标PUCCH的序列信息的序列长度为12,目标PRB的数量为3的情况下,假设目标PRB分别为PRB1、PRB2、PRB3,则UE可以将上述目标PUCCH的12个序列信息先映射在PRB1上,然后将上述目标PUCCH的12个序列信息映射在PRB2上,然后将上述目标PUCCH的12个序列信息映射在PRB3上。
在一种示例中,在预设方式为在上述N个目标PRB上循环移位。
需要说明的是,循环移位的索引可以和N个目标PRB的索引相关。
在一种示例中,在预设方式为在上述N个目标PRB中的部分PRB之间相位旋转;一个上述部分PRB包括上述目标PRB中的部分RE。

示例4:结合上述示例2,在确定N个目标PRB的位置信息后,目标PUCCH的序列长度为12,则PUCCH的序列信息分别根据各自的循环移位得到序列映射到各自的PRB上。
如此,在PUCCH为格式0或者格式1的情况下,可以根据目标PUCCH序列信息的序列长度的不同,选择使用不同的映射方法进行映射,进而丰富了UE将PUCCH的序列信息映射至PRB上的方式方法。

示例性的,在UE增加目标DMRS后,由于DMRS也需要和PUCCH同步占用PRB进行信息传输,因此,可以重新确定目标PUCCH的序列信息在每个目标PRB上的映射的序列长度。例如:在目标PUCCH的序列信息的序列长度为12,在增加目标DMRS之前,确定目标PUCCH的序列信息在每个目标PRB上的长度为12,在UE增加目标DMRS后,可以重新确定目标PUCCH的序列信息在每个目标PRB上的长度为6。
示例性的,在UE增加目标DMRS后,重新确定的目标PUCCH的序列信息在每个目标PRB上的映射的序列长度为可以为RRC配置或者固定或者预定义。
例5:假设目标PRB数量为2,分别为PRB1和PRB2,每个PRB上包括12个RE,目标PUCCH的序列信息的序列长度为12,则在UE未增加目标DMRS之前,UE可以将目标PUCCH的全部序列信息映射在PRB1的每个RE上,并将目标PUCCH的全部序列信息重复映射在PRB2的每个RE上。
在UE增加目标DMRS之后,DMRS的信息长度为6,则UE可以将目标PUCCH的序列信息分为两部分,每部分的序列信息的序列长度为6,则此时,映射方式为:将DMRS的信息(长度为6)和PUCCH的部分序列信息(长度为6)映射在PRB1的每个RE上,然后再将剩余的PUCCH的序列信息(长度为6)和上述DMRS的信息(长度为6)映射在PRB2的每个RE上。
如此,UE可以通过增加目标DMRS,可以在不影响PUCCH序列信息传输的情况下增强频带利用效率。
可选的,在本申请实施例中,在上述目标PUCCH为格式0的情况下,在上述步骤209之前,本申请实施例提供的资源映射方法可以包括如下步骤211:
步骤211:UE增加目标DMRS,并将上述目标DMRS和上述目标PUCCH在时域复用。
