本公开实施例提供了一种上行功率控制参数配置方法,应用于终端侧,如图1所示,该方法可以包括以下步骤:
步骤11:接收网络设备发送的功率控制参数集合。
其中,功率控制参数集合包括至少一项功率控制项的参数集合,每项功率控制项的参数集合包括功率控制项的至少一个参数配置索引值或参数取值。也就是说,功率控制参数集合中包括不同功率控制项的参数集合,同一功率控制项参数集合中包括该功率控制项下的全部或部分参数配置索引值或参数取值。可选地,终端可通过高层信令接收网络设备发送的功率控制参数集合。
在一种实施例中,功率控制项包括:目标接收功率、路损补偿因子、路损计算参考的下行信道或参考信号的资源标识和闭环功率控制的进程标识等。值得指出的是不同场景下,功率控制参数集合中所关联的功率控制项的种类不同,功率控制参数集合中所包含的功率控制项的参数集合也不同。
步骤12:在功率控制参数集合的功率控制项的参数集合中,为第一功率控制项选择目标参数配置索引值或目标参数取值。
其中,值得指出的是,这里所说的第一功率控制项可以是功率控制参数 集合功率控制项中的一项或多项。所属领域技术人员可以理解,这里仅以第一功率控制项为一项功率控制项为例进行说明,所属领域技术人员可以为多个功率控制项,或者全部功率控制项,选择目标参数配置索引值或者目标参数取值。这里第一功率控制项仅为示例,不构成对本公开的限制。
假设功率控制参数集合中包括:目标接收功率、路损补偿因子、路损计算参考的下行信道或参考信号的资源标识,以及闭环功率控制的进程标识等功率控制项的参数集合,那么终端从中确定出目标接收功率的目标参数配置索引值或目标参数取值,路损补偿因子的目标参数配置索引值或目标参数取值、路损计算参考的下行信道或参考信号的资源标识的目标参数配置索引值或目标参数取值,以及闭环功率控制的进程标识的目标参数配置索引值或目标参数取值。
步骤13:根据目标参数配置索引值或目标参数取值,确定上行信道或上行参考信号的目标发射功率。
将步骤12确定的功率控制项的目标参数配置索引值或目标参数取值,代入上行信道或上行参考信号的目标发射功率的计算公式中,即可确定上行信道或上行参考信号的目标发射功率。在一种实施例中,上行信道包括以下至少一项:物理上行控制信道PUCCH,物理上行共享信道PUSCH,以及物理随机接入信道PRACH,所述上行参考信号包括探测参考信号SRS。
以PUSCH为例,上述功率控制参数集合所关联的功率控制项包括:目标接收功率、路损补偿因子、路损计算参考的下行信道或参考信号的资源标识,以及闭环功率控制的进程标识。高层信令配置的功率控制参数集合配置示意如下:
目标接收功率和路损补偿因子集合,如P 0和α参数集合{
{P 0和α参数配置索引值0,{P 0_0,α _0}},
{P 0和α参数配置索引值1,{P 0_1,α _1}},
…}
路损计算参考的下行信道或参考信号资源标识参数集合{
{路损计算参考的下行信道或参考信号资源标识0,信道状态信息参考信号(Channel State Information Reference Signals,CSI-RS)标识0},
{路损计算参考的下行信道或参考信号资源标识1,CSI-RS标识1},
{路损计算参考的下行信道或参考信号资源标识2,同步信号块(Synchronous Signal Block,SSB)标识0},
{路损计算参考的下行信道或参考信号资源标识3,SSB标识1},
…}
闭环功率控制进程参数集合{
{闭环功率控制进程0,0},
{闭环功率控制进程1,1},
…}
以PUCCH为例,上述功率控制参数集合所关联的功率控制项包括:目标接收功率、路损计算参考的下行信道或参考信号的资源标识,以及闭环功率控制的进程标识。
以PRACH为例,上述功率控制参数集合所关联的功率控制项包括:路损计算参考的下行信道或参考信号的资源标识。
以SRS为例,上述功率控制参数集合所关联的功率控制项包括:目标接收功率、路损补偿因子、路损计算参考的下行信道或参考信号的资源标识,以及闭环功率控制的进程标识。
下面本实施例将结合具体实现方式对步骤12进行说明,以下列举的不同方式可独立实现目标参数配置索引值或目标参数取值的确定,亦可联合实现目标参数配置索引值或目标参数取值的确定。
方式一、根据下行控制信息DCI,为第一功率控制项选择目标参数配置索引值或目标参数取值。
其中,DCI中携带有下行授权信息和上行授权信息中的至少一项,下行授权信息可指示SRS的功率控制信息,上行授权信息可指示PUSCH、PUCCH、PRACH和SRS中的至少一项的功率控制信息。
在一种实施例中,该方式可参照以下步骤实现:检测DCI中是否存在目标指示域,若检测到目标指示域,则根据目标指示域,为第一功率控制项选择目标参数配置索引值或目标参数取值。其中,目标指示域用于指示第一功率控制项的参数配置索引值或参数取值,第一功率控制项为功率控制参数集 合中功率控制项的至少一项。
其中,目标指示域独立编码,或者,与其他指示域联合编码。
以独立编码为例,DCI中指定目标指示域(或称为功率控制参数配置索引值域)专门用于指示目标功率控制项的参数配置索引值或参数取值,其中,本实施例仅以目标功率控制项的参数配置索引值为例进行说明。如表1所示,
表1
第一指示域 目标功率控制项的参数配置索引值
00 0
01 1
10 2
11 3
其中,目标指示域中不同的取值用于指示不同的目标功率控制项的参数配置索引值,其中,目标功率控制项可以是目标接收功率、路损补偿因子、路损计算参考的下行信道或参考信号的资源标识和闭环功率控制的进程标识中的一项或多项。
当目标指示域为独立编码时,在检测DCI中的目标指示域的步骤之前还可以包括:接收网络设备发送的用于指示DCI中是否存在目标指示域的指示信息;若检测到所述指示信息,且指示信息指示存在目标指示域,则执行检测DCI中是否存在目标指示域的步骤;若未检测到指示信息指示,则通过方式二或方式三确定功率控制参数集合中功率控制项的目标参数配置索引值或目标参数取值。具体地,这里所说的未检测指示信息指的是:指示信息不存在,或者检测到指示信息指示不存在目标指示域,则执行将第一功率控制项的默认参数配置索引值或默认参数取值,确定该第一功率控制项的目标参数配置索引值或目标参数取值的步骤;或者,执行根据已确定参数配置索引值或参数取值的第二功率控制项,确定第一功功率控制项的目标参数配置索引值或目标参数取值的步骤,其中,第二功率控制项与第一功率控制项相关联。在一种可选实施例中,终端可通过高层信令接收用于指示目标指示域(或称为功率控制参数配置索引值域)是否存在的指示信息,当指示信息为0表示不存在,为1表示存在。
以联合编码为例,DCI中未指定专门用于指示目标功率控制项的参数配置索引值或参数取值的指示域,而是通过复用其他已定义的指示域来指示目标功率控制项的参数配置索引值或参数取值。其中,本实施例以复用SRS请求域(目标指示域)为例进行说明。如表2所示,
表2
SRS请求域 描述 功率控制参数配置索引值
00 非类型1外的SRS指示 0
01 第1SRS资源集合,由高层配置 1
10 第2SRS资源集合,由高层配置 2
11 第3SRS资源集合,由高层配置 3
其中,SRS请求域中不同取值除了可指示不同SRS请求资源外,还可进一步指示不同目标功率控制项的参数配置索引值。
进一步地,考虑到网络传输环境或终端DCI检测失败等场景,以终端DCI检测失败为例,检测DCI中是否存在目标指示域,若未检测到目标指示域,则通过方式二或方式三确定功率控制参数集合中功率控制项的目标参数配置索引值或目标参数取值。具体地,未检测到目标指示域指的是:目标指示域不存在,或目标指示域检测失败,则执行将第一功率控制项的默认参数配置索引值或默认参数取值,确定为该第一功率控制项的目标参数配置索引值或目标参数取值的步骤;或者,执行根据已确定参数配置索引值或参数取值的第二功率控制项,确定第一功率控制项的目标参数配置索引值或目标参数取值的步骤。
方式二、将第一功率控制项的默认参数配置索引值或默认参数取值,确定为该第一功率控制项的目标参数配置索引值或目标参数取值。
其中,该方式为预配置方式,也就是说协议或网络设备提前配置了不同业务下功率控制项的默认参数配置索引值或默认参数取值,虽然网络设备通过高层信令配置了功率控制参数集合,但终端可从该功率控制参数集合中选择不同功率控制项各自对应的默认参数配置索引值或默认参数取值,确定为相应功率控制项的目标参数配置索引值或目标参数取值。假设各功率控制项下的默认参数配置索引值为0。
方式三、根据已确定参数配置索引值或参数取值的第二功率控制项,确定第一功率控制项的目标参数配置索引值或目标参数取值。
其中,终端在根据已确定参数配置索引值或参数取值的第二功率控制项,确定第二功率控制项的目标参数配置索引值或目标参数取值的步骤之前,还包括:获取功率控制参数集合中多个功率控制项之间关联关系。获取多个功率控制项之间关联关系的方式包括但不限于以下几种:协议预先定义好多个功率控制项之间关联关系,网络设备为终端配置多个功率控制项之间关联关系。其中,网络设备配置方式中,终端可通过网络设备的广播信息获取到多个功率控制项之间关联关系,终端可通过高层信令接收各功率控制项之间关联关系等。
其中,多个功率控制项之间的关联关系包括一对一、一对多或多对一的关系。以一对一的关系为例,基于波束的功率控制时,{P 0和α参数配置索引值0,路损计算参考的下行信道或参考信号资源标识0,闭环功率控制进程0}。以一对多的关系为例,基于波束组的功率控制,{P 0和α参数配置索引值0,路损计算参考的下行信道或参考信号资源标识0,路损计算参考的下行信道或参考信号资源标识1}。以多对一的关系为例,基于波束组,载波的功率控制,{路损计算参考的下行信道或参考信号资源标识0,路损计算参考的下行信道或参考信号资源标识1,闭环功率控制进程0}。
该方式为隐式确定方式,即当确定部分功率控制项的目标参数配置索引值或目标参数取值后,根据多个功率控制项之间的关联关系可确定其他功率控制项的目标参数配置索引值或目标参数取值。假设当确定路损计算参考的下行信道或参考信号资源标识0时,即可确定P 0和α参数配置索引值为0,闭环功率控制进程为0。
以上介绍了三种方式独立确定功率控制项的目标参数配置索引值或目标参数取值的场景,下面将进一步介绍不同方式联合确定的场景。
在一种实施例中,可默认采用方式二,并通过方式一中DCI指示部分功率控制项的参数,如路损计算参考下行信道或参考信号资源标识,再通过方式三隐式得到P 0和α。在另一种实施例中,可优先采用方式一,若方式一无法确定全部功率控制项的目标参数配置索引值或目标参数取值时,再采用方 式二或方式三进行确定。
具体地,若通过方式一仅确定了功率控制参数集合中部分功率控制项的目标参数配置索引值或目标参数取值,那么还可联合方式三确定其他功率控制项的目标参数配置索引值或目标参数值,即,根据已确定的部分功率控制项与其他功率控制项之间的关联关系确定其他功率控制项的目标参数配置索引值或目标参数取值。具体地,在根据目标指示域,为第一功率控制项选择目标参数配置索引值或目标参数取值的步骤之后还包括:根据第一功率控制项,确定其他功率控制项的目标参数配置索引值或目标参数取值;其中,其他功率控制项与该第一功率控制项相关联。
以PUSCH功率控制过程中,路损计算参考的参考信道的资源标识(或称为PL参考RS标识)与SRS请求域联合编码,即PL参考RS标识由SRS请求域隐式指示,如表3所示,高层信令预配置PL参考RS标识与目标接收功率P 0和路损补偿因子α映射关系,如表4所示。
表3
SRS请求域 描述 PL参考RS标识
00 非类型1外的SRS指示 0

11 第3SRS资源集合,由高层配置 3
表4
P 0和α 2 3 4 5
PL参考RS标识 0 1 2 3
PUSCH功率控制过程中,目标接收功率P 0和路损补偿因子α由DCI中功率控制参数配置索引值域(本实施例以P 0和α参数域为例)显式指示,如表5所示,路损计算参考的参考信道的资源标识(或称为PL参考RS标识)由SRS请求域隐式指示,如表6所示。高层信令预配置PL参考RS标识与目标接收功率P 0和路损补偿因子α映射关系,如表7所示。

应理解的是,本公开实施例中,射频单元31可用于收发信息或通话过程中,信号的接收和发送,具体的,将来自基站的下行数据接收后,给处理器310处理;另外,将上行的数据发送给基站。通常,射频单元31包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器、双工器等。此外,射频单元31还可以通过无线通信系统与网络和其他设备通信。
