Description

一种功率控制方法、终端和基站 技术领域
本发明涉及通信技术领域,尤其涉及一种功率控制方法、终端和基站。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)高级长期演进(Long Term Evolution-Advanced,LTE-A)系统具有更高的带宽要求,以支持下行、上行的数据速率。为了满足LTE-A的要求,LTE-A系统将载波汇聚(Component Aggregation,CA)技术作为其扩展带宽的方法,并采用多天线增强技术(多入多出,Multiple-Input Multiple-Output,MIMO)和多点协作技术(Coordinated Multi-Point,CoMP),以提高数据速率和系统性能。
在LTE-A中,物理上行控制信道(Physical Uplink Control Channel,PUCCH)、物理上行共享信道(PUSCH,Physical Uplink Shared Channel)都有明确的功率控制公式,而侦听参数信号(SRS,Sounding Reference Signal)的功率控制则是在PUSCH的发射功率上增加一个offset偏移量。其中,计算PUCCH的功率控制公式为:
Figure PCTCN2015078839-appb-000001
其中,PPUCCH(i)表示子帧i上的PUCCH信道的发射功率,PCMAX,c表示UE在载波c上的最大功率发射,P0_PUCCH表示PUCCH信道开环功率,PLc表示在载波c上的路径损耗,ΔF_PUCCH(F)表示是对不同的PUCCH格式的补偿,h(nCQI,nHARQ,nSR)是对相同的PUCCH格式下不同上行控制信息(Uplink Control Information,UCI)比特数的补偿,g(i)表示功控动态偏移,
Figure PCTCN2015078839-appb-000002
第i个上行子帧相对于第i-1个上行子帧有一个TPC累积量,δPUCCH为下行调度信令DCI格式1/1A/1B/1D/2/2A/2B)或DCI格式3/3A中的TPC功控命令指示的闭环修正系数,ΔTxD(F')是与多天线端口相关的参数,且当PUCCH只占用一个天线端口时ΔTxD(F')=0。
h(nCQI,nHARQ,nSR)是对PUCCH中不同的UCI比特数的补偿,其中nCQI是信道质量指示(Channel Quality Indicator,CQI)的比特数,nHARQ是混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)的比特数,nSR是调度请求SR的比特数。
当PUCCH格式为1,1a和1b时,
h(nCQI,nHARQ,nSR)=0;
当PUCCH格式为2,2a和2b,并且是常规循环前缀(normal cyclic prefix,NCP)时,
Figure PCTCN2015078839-appb-000003
当PUCCH格式为2,并且是扩展循环前缀(extended cyclic prefix,ECP)时,
Figure PCTCN2015078839-appb-000004
当PUCCH格式为3,并且比特数超过11比特时,
Figure PCTCN2015078839-appb-000005
当PUCCH格式为3,并且比特数小于或等于11比特时,
Figure PCTCN2015078839-appb-000006
而为了进一步提高峰值数据速率和系统吞吐量,大规模载波聚合Massive CA被引入,以支持最大32个载波的聚合,上行或下行最大聚合的载波数量 都可能达到32个。由于下行最大聚合的载波数量可能达到32个,因而上行需要反馈的上行控制信息(Uplink Control Information,UCI)会成倍的增加,开销较大,现有的PUCCH将面临容量不够的问题。然而,现有的功率控制机制不能对支持最多32个载波的UCI在PUCCH上反馈时的PUCCH进行功率控制。

具体实施方式
下面将结合本发明实施例中的附图,对本发明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发明的一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例,都应属于本发明保护的范围。
应理解,在本发明实施例中,PUCCH的新格式可以包括下面几种:
1.在频域上可以使用多个资源块(Resource Block,RB)传输一个PUCCH;
2.在码域上可以使用多路里德-穆勒(Reed-Muller,RM)码传输一个PUCCH;
3.在时域上可以将时域上的多个符号分成多组,每组使用长度更短的正交掩码(Orthogonal Cover Code,OCC),每组符号传输一个PUCCH;
4.使用不同的缩放因子(Spreading Factors,SF);
5.对不同的PUCCH格式或不同的PUCCH比特数使用不同的编码格式,如:除了现在用于PUCCH的RM码,还考虑使用现在用于PDCCH的Turbo码(Turbo Code,TC),或使用现在用于PUSCH的咬尾卷积码(Tail Biting Convolutional Code,TBCC),则不同的编码格式可以对应不同的编码因子(Coding Factors,CF);
6.不同的PUCCH格式或不同的PUCCH比特数使用不同的调制方式,如:除了现在用于PUCCH格式1a的双相移相键控(Binary Phase Shift Keying,BPSK)和现在用于PUCCH格式1b/2/2a/2b/3的正交相移键控(Quaternary Phase Shift Keying,QPSK),还考虑使用16正交振幅调制(Quadrature Amplitude Modulation,QAM)或更高阶调制,则不同的调制方式可以对应不同的调制因子(Modulation Factors,MF)。
还应理解,在本发明实施例中,终端也可以称为系统、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理、用户装置或用户设备(UE,User Equipment)。终端可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol,会话启动协议)电话、WLL(Wireless Local Loop,无线本地环路)站、PDA(Personal Digital Assistant,个人数字处理)、具有无线通信功能的手持设备、车载设备、计算设备或连接到无线调制解调器的其它处理设备。
还应理解,在本发明实施例中,基站可用于与移动设备通信,基站可以是Wi-Fi的AP(Access Point,无线接入点),或者是GSM(Global System of Mobile communication,全球移动通讯)或CDMA(Code Division Multiple Access,码分多址)中的BTS(Base Transceiver Station,基站),也可以是WCDMA(Wideband Code Division Multiple Access,宽带码分多址)中 的NB(NodeB,基站),还可以是LTE(Long Term Evolution,长期演进)中的eNB或eNodeB(Evolutional Node B,演进型基站),或者中继站或接入点,或者未来5G网络中的基站设备等。
图1是根据本发明实施例的一种功率控制方法100的示意性流程图。如图1所示的方法100可以由终端来执行,所述方法100包括:
110,获取物理上行控制信道PUCCH的参数信息,所述参数信息包括所述PUCCH的资源块RB的数量信息、RM码的数量信息、正交掩码OCC的数量信息、编码格式信息、调制格式信息,以及缩放因子SF的数值信息中的一种信息或多种信息,或所述参数信息包括与所述PUCCH的所述RB的数量信息、所述RM码的数量信息、所述OCC的数量信息、所述编码格式信息、所述调制格式信息,以及所述SF的数值信息中的一种信息或多种信息相对应的至少一个配置参数;
120,根据所述参数信息计算所述PUCCH的发射功率;
130,根据所述计算出的所述PUCCH的发射功率发射所述PUCCH。
具体的,在本发明实施例中,可以根据获取的PUCCH的参数信息计算所述PUCCH的发射功率,并根据该发射功率发射PUCCH,该参数信息可以包括该PUCCH的资源块RB的数量信息、RM码的数量信息、正交掩码OCC的数量信息、编码格式信息、调制格式信息,以及缩放因子SF的数值信息中的一种信息或多种信息。也就是说,该参数信息可以为上述6种信息中的任一种,或者也可以为上述6种信息中任意多种信息的组合。当该参数信息包括编码格式信息时,可以根据该编码格式信息与第一数值的对应关系,确定第一数值,用以计算该PUCCH的发射功率。而当该参数信息包括调制格式信息时,可以根据该调制格式信息与第二数值的对应关系,确定第二数值,用以计算该PUCCH的发射功率。或者,当该参数信息包括与该PUCCH的该RB的数量信息、该RM码的数量信息、该OCC的数量信息、该编码格式信息、该调制格式信息,以及该SF的数值信息 中的一种信息或多种信息相对应的至少一个配置参数。也就是说,该参数信息可以为上述6种信息中的任一种,或者也可以为上述6种信息中任意多种信息的组合,则与之对应的配置参数也可以为一个或者多个。
因此,本发明实施例提供的一种功率控制方法,通过获取PUCCH的参数信息,并根据该参数信息计算PUCCH的发射功率,从而解决支持最多32个载波的UCI在PUCCH上反馈时PUCCH的功率控制问题。
应理解,在本发明实施例中,编码格式信息与第一数值的对应关系和/或调制格式信息与第二数值的对应关系可以由终端预配置,或可以从基站发送的配置信息中获取,本发明实施例对此并不做限定。例如,编码格式信息与第一数值的对应关系,以及调制格式信息与第二数值的对应关系可以如下述表1所示:
编码格式信息CF 第一数值 调制格式信息MF 第二数值
CF=TC 1 MF=BPSK 1
CF=RM 3 MF=QPSK 0
CF=TBCC 0.8 MF=16QAM 5
还应理解,在本发明实施例中,当PUCCH的参数信息为RB的数量信息、RM码的数量信息、OCC的数量信息、编码格式信息、调制格式信息,以及SF的数值信息中的一种信息时,接收到的基站发送的配置参数为与之对应的一个参数。上述6种信息中的每一种信息对应一个参数,如下述表2所示:
NRB_PUCCH NRM NOCC CF MF SF
α β γ δ ε ω
而同一参数的不同值对应同一种信息的不同物理量,如下述表3所示:
α=1 NRB_PUCCH=10 δ=1 CF=TC
α=2 NRB_PUCCH=1 δ=0.5 CF=RM
α=3 NRB_PUCCH=5 δ=0.2 CF=TBCC
β=1 NRM=1 ε=-1 MF=BPSK
β=2 NRM=2 ε=1 MF=QPSK
β=3 NRM=3 ε=0 MF=16QAM
γ=1 NOCC=5 ω=-1 SF=6
γ=0.5 NOCC=3 ω=1 SF=4
γ=1.5 NOCC=1 ω=4 SF=3
例如:当基站根据上述表3确定了PUCCH的参数信息为RB的数量信息,且NRB_PUCCH=10,则配置参数α=1,并向终端发送该配置参数,以便终端根据该配置参数计算PUCCH的发射功率。而当基站根据上述表3确定了PUCCH的参数信息为RB的数量信息,RM码的数量信息和OCC的数量信息,且NRB_PUCCH=10,NRM=2,NOCC=1,则配置参数α=1,β=1和γ=1.5,并向终端发送该配置参数,以便终端根据该配置参数计算PUCCH的发射功率。
可选的,作为本发明的一个实施例,在120中可以根据所述参数信息计算所述PUCCH的发射功率的增加量,并根据第一参数以及所述增加量计算所述PUCCH的发射功率。
应理解,在本发明实施例中,所述增加量可以为参数信息的线性函数、对数函数或指数函数,但本发明实施例对此并不做限定,例如:还可以是可以为参数信息的其它的函数。
需要说明的是,在本发明实施例中,增加量是指计算PUCCH的发射功率时除信道开环功率、路径损耗、功控动态偏移以及补偿量等参数之外的,且与传输所述PUCCH的格式、内容和天线端口数相关的参数。增加 量的值可以为正数也可以为负数,这个需要根据实际情况确定,本发明实施例对此并不做限定。
例如:在本发明实施例中,作为计算所述PUCCH的发射功率的增加量的参数信息可以为RB的数量信息NRB_PUCCH,如:NRB_PUCCH=10,且该增加量为:10log10(NRB_PUCCH),那么计算PUCCH的发射功率的公式为:

应理解,在本发明实施例中,可以将所述参数信息作为计算所述PUCCH的发射功率的公式中的与所述PUCCH相关的项的系数。通常情况下,可以作为与传输PUCCH格式、内容和天线端口数相关的项的系数。例如:可以作为计算所述PUCCH的发射功率的公式中的h(nCQI,nHARQ,nSR)、ΔF_PUCCH(F)和ΔTxD(F')的系数,但本发明实施例并不局限于此。
还应理解,在本发明实施例中,所述第一参数的系数可以为参数信息的线性函数、对数函数或指数函数,但本发明实施例对此并不做限定,例如:还可以是可以为参数信息的其它的函数。
例如:在本发明实施例中,作为计算所述第一参数的系数的参数信息可以为RB的数量信息NRB_PUCCH,那么计算PUCCH的发射功率的公式为:

还需要说明的是,上述参数信息还可以作为/或替换计算所述PUCCH的发射功率的公式中的其它第一参数的系数,或者,同时作为多个第一参数的系数,且每个第一参数的系数可以是参数信息的相同函数,也可以是不同的函数。
再如:在本发明实施例中,作为计算所述PUCCH的发射功率的公式中的第一参数的系数的参数信息可以为RB的数量信息NRB_PUCCH,RM码的数量信息NRM,和OCC的数量信息NOCC。该参数信息分别作为多个第一参数的系数,那么PUCCH的功率控制公式为:

该参数信息也可以作为一个第一参数,如:ΔF_PUCCH(F)的系数,那么PUCCH的功率控制公式为:
