具体实施方式
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象,而不是用于限定特定顺序。
在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为方便理解本申请实施例,首先在此介绍本申请实施例所涉及到的相关要素。
PH为终端设备的最大传输功率(用P MAX表示)与计算的终端设备的配置传输功率(用P C-Data表示)之间的差值。其中,终端设备的配置传输功率为在传输终端设备的上行信道的情况下,网络设备为该终端设备配置的功率。终端设备的上行信道可以为PUSCH、PUCCH、NR-PUSCH或NR-PUCCH。
可以理解的是,无论终端设备的上行信道为PUSCH、PUCCH、NR-PUSCH以及NR-PUCCH中的哪一种,均可执行本申请实施例提供的功率余量的传输方法。
为便于描述,本申请实施例以终端设备的上行信道为PUSCH为例进行说明。
示例性的,在终端设备的上行信道为PUSCH的情况下,PH的计算公式可以用公式(1)表示。
PH=P MAX-P C-Data   (1)
其中,P C-Data的计算公式可以用公式(2)表示。
P C-Data=10 log 10M+P 0+α·PL+Δ TF+f   (2)
上述公式(2)中,M为当前PUSCH占用的资源块的数量,即PUSCH所调度的资源块(Resource Block,RB)的数量,P 0为开环功控调整值,α为部分路损补偿值,PL为终端设备计算的路损的数值,Δ TF为传输格式补偿值,f为闭环功控调整值。
从上述公式(2)可以看出,计算的终端设备的配置传输功率与当前PUSCH占用资源的带宽、终端设备与基站之间的路损、开环功控以及闭环功控的配置均有关系。
在PH信息被触发上报后,当终端设备有上行调度资源可以容纳PH信息时,终端设备向网络设备发送其PH信息,便于该网络设备对该终端设备进行资源调度以及功率控制。一般的,终端设备在媒体访问控制(Media Access Control,MAC)层控制单元(Control Element,CE)中向网络设备上报其PH信息。具体的,终端设备生成一个PH MAC CE,并将其上报给网络设备。如果终端设备上报的PH信息反映出该终端设备有较大的功率余量,那么网络设备可以分配较多的无线资源块给该终端设备。如果终端设备上报的PH信息反映出该终端设备已经没有功率余量,或者没有较多的功率余量,那么网络设备只能分配较少的无线资源块或者低阶调制命令给该终端设备。
3GPP NR标准中规定上行链路同时采用OFDM波形和DFT-S-OFDM波形传输数据,这样,网络设备需要获取到采用OFDM波形传输数据时终端设备的PH信息以及采用DFT-S-OFDM波形传输数据时终端设备的PH信息。但是,目前还不存在网络设备获取这两种PH信息的方法。
针对这一问题,本申请实施例提供一种功率余量的传输方法,对于支持采用第一波形和第二波形传输数据的终端设备而言,该终端设备可直接向网络设备发送其确定的第一功率余量信息和第二功率余量信息,或者,该终端设备确定第一功率余量信息和Δ M,并向网络设备发送第一功率余量信息和Δ M,便于网络设备根据第一功率余量信息、Δ M以及其他相关信息确定第二功率余量信息,这样,网络设备可根据第一功率余量信息和第二功率余量信息调度终端设备。
本申请实施例提供的功率余量的传输方法适用于通信系统,图1是本申请实施例提供的通信系统的结构图。如图1所示,该通信系统包括终端设备10和网络设备11。实际应用中,该通信系统通常包括多个终端设备10和网络设备11,为简化本系统的讨论,在图1中只示出单个终端设备10和网络设备11。
终端设备10支持采用不同类型的两种波形传输数据,该终端设备10可以向网络设备11发送PH信息,该PH信息可以包括:用于标识终端设备的最大传输功率与计算的终端设备的配置传输功率之间的差值的信息。终端设备10可以定期地发送PH信息,也可以在下行链路路径损耗改变量超过门限时发送PH信息。
终端设备10可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备10可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信。终端设备10可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接 入网交换语言和/或数据,例如,手机、平板电脑、笔记本电脑、上网本、个人数字助理(Personal Digital Assistant,PDA)。

下面将具体解释本申请实施例提供的功率余量的传输方法。
本申请实施例提供的功率余量的传输方法可以应用在图1所示的通信系统中。由上述描述可知,本申请实施例中的终端设备10支持采用不同类型的两种波形传输数据,以终端设备支持第一波形和第二波形传输数据为例进行说明,其中,采用第一波形传输数据时终端设备的最大功率为第一最大功率P MAX1,采用第二波形传输数据时终端设备的最大功率为第二最大功率P MAX2,第一功率余量信息用于表示采用第一波形传输数据时终端设备的功率余量PH 1,第二功率余量信息用于表示采用第二波形传输数据时终端设备的功率余量PH 2,第一配置传输功率P C-Data1为终端设备的PUSCH采用第一波形传输时网络设备为终端设备配置的功率,第二配置传输功率P C-Data2为终端设备的PUSCH采用第二波形传输时网络设备为终端设备配置的功率,第一配置传输功率与第二配置传输功率之间的差值为第二功率差ΔP C-Data
具体的,本申请实施例提供的功率余量的传输方法可以为:
(1)、第一最大功率与第二最大功率之间的差值为Δ M,终端设备确定第一功率余量信息和Δ M,并向网络设备发送第一功率余量信息和Δ M。相对应的,网络设备接收终端设备发送的第一功率余量信息和Δ M,此外,网络设备还获取第二功率差,这样,网络设备根据第一功率余量信息、Δ M以及第二功率差即可确定出第二功率余量信息,进而根据第一功率余量信息和第二功率余量信息实现对终端设备的资源调度。
(2)、终端设备确定第一功率余量信息和第二功率余量信息,并向网络设备发送其确定的第一功率余量信息和第二功率余量信息,便于网络设备根据第一功率余量信息和第二功率余量信息实现对终端设备的资源调度。
这里先对上述方法(1)进行说明。如图4所示,本申请实施例提供的功率余量的传输方法包括:
S400(可选的)、终端设备向网络设备发送Δ M
本申请实施例中的Δ M可以为系统预先配置的,也可以为终端设备根据第一最大功率P MAX1和第二最大功率P MAX2计算得到的,如Δ M=P MAX1-P MAX2
在终端设备根据第一最大功率和第二最大功率计算得到Δ M的场景中,终端设备还需向网络设备发送其计算得到的Δ M
可选的,终端设备向网络设备发送Δ M的方法可以为终端设备向网络设备发送携带有Δ M的初始接入Msg3消息,也可以为在PUSCH的传输过程中,终端设备向网络设备发送携带有Δ M的高层信令,本申请实施例对此不作具体限定。
可选的,终端设备可以在接收到网络设备发送的用于指示上报Δ M的消息后向网络设备发送Δ M,也可以是根据系统的配置向网络设备发送Δ M,本申请实施例对此不作具体限定。
由于S400为可选步骤,因此图4中用虚线表示。
S401、终端设备确定第一功率余量信息。
从上面描述可知,该终端设备支持第一波形和第二波形传输数据,这样,该终端 设备可确定出第一功率余量信息或第二功率余量信息。可选的,终端设备可以根据系统预先配置确定计算哪一种功率余量信息,也可以在接收到网络设备发送的高层信令确定计算哪一种功率余量信息,本申请实施例对此不作具体限定。
本申请实施例以终端设备确定第一功率余量信息为例进行说明。
具体的,在终端设备的PUSCH采用第一波形传输的情况下,该终端设备根据第一最大功率P MAX1和第一配置传输功率P C-Data1确定第一功率余量信息。
示例性的,终端设备根据公式(3)以及公式(4)计算第一功率余量信息。
PH 1=P MAX1-P C-Data1   (3)
P C-Data1=10 log 10M 1+P 0+α·PL+Δ TF+f   (4)
其中,M 1为该终端设备PUSCH采用第一波形进行传输时占用的资源块的数量,即该终端设备的PUSCH采用第一波形进行传输时所调度的RB的数量。其余参数可以参考上述公式(1)的描述,此处不再进行详细赘述。
在该终端设备的PUSCH未采用第一波形传输,而是采用第二波形传输的情况下,该终端设备可以根据第一最大功率P MAX1和第二配置传输功率P C-Data2确定第一功率余量信息。
示例性的,在终端设备的PUSCH未采用第一波形传输,而是采用第二波形传输的情况下,终端设备根据公式(5)以及公式(6)计算第一功率余量信息。
PH 1=P MAX1-P C-Data2   (5)
P C-Data2=10 log 10M 2+P 0+α·PL+Δ TF+f   (6)
其中,M 2为该终端设备的PUSCH采用第二波形进行传输时占用的资源块的数量,即该终端设备的PUSCH采用第二波形进行传输时所调度的RB的数量。其余参数可以参考上述公式(1)的描述,此处不再进行详细赘述。
在该终端设备的PUSCH未采用第一波形传输,而是采用第二波形传输的情况下,该终端设备确定第一功率余量信息的方法除了上述根据第一最大功率P MAX1和第二配置传输功率P C-Data2确定之外,也可以为该终端设备不考虑PUSCH的调度,根据预设公式确定第一功率余量信息。

S403、网络设备根据第一功率余量信息、Δ M以及第二功率差,计算得到第二功率 余量信息。
可选的,若S400中终端设备向网络设备发送Δ M,则该网络设备是从终端设备接收Δ M。若Δ M是系统预先配置的,则该网络设备可直接获取到Δ M
第二功率差ΔP C-Data为第一配置传输功率与第二配置传输功率的差值,网络设备可直接获取到第二功率差。
结合上述公式(1)以及上述公式(2),在网络设备获取到第一功率余量信息、Δ M以及第二功率差的情况下,网络设备可计算出第二功率余量信息。
示例性的,网络设备可以根据下述公式计算得到第二功率余量信息PH 2
PH 2=PH 1M+ΔP C-Data或者PH 2=PH 1M-ΔP C-Data
S404、网络设备根据第一功率余量信息和第二功率余量信息,调度终端设备。
进一步地,在第一波形和第二波形中仅存在一个波形支持SS的情况下,终端设备还向网络设备发送该波形对应的第一功率差信息或者该波形对应的额外功率信息,便于网络设备确定在SS的作用下,终端设备的功率余量信息,进而更加充分的调度终端设备的资源。
其中,该波形对应的第一功率差的数值等于采用添加SS的第一调制方式调制该波形时终端设备的最大传输功率与采用第二调制方式调制该波形时终端设备的最大传输功率之间的差值。额外功率的数值等于采用添加SS的第一调制方式调制该波形时终端设备的最大传输功率与采用未添加SS的第一调制方式调制该波形时终端设备的最大传输功率之间的差值。
第一调制方式可以是在添加SS后,终端设备所使用的带宽未扩展或者扩展很小的调制方式。例如pi/2二进制相移键控(Binary Phase Shift Keying,BPSK)调制方式。
第二调制方式可以是在添加SS后,终端设备所使用的带宽扩展较大的调制方式。例如正交相移键控(Quadrature Phase Shift Keying,QPSK)方式。
本申请实施例以第一调制方式为pi/2-BPSK调制方式,第二调制方式为QPSK调制方式为例进行说明。第一波形采用添加SS的pi/2-BPSK调制方式调制时终端设备的最大功率表示为P MAX11,第一波形采用QPSK调制方式调制时终端设备的最大传输功率表示为P MAX12,终端设备采用P MAX11计算得到的第一功率余量信息表示为PH 11,终端设备采用P MAX12计算得到的第一功率余量信息表示为PH 12,与第一波形对应的第一功率差表示为ΔP 10,与第一波形对应的额外功率表示为ΔP 11,第二波形采用添加SS的pi/2-BPSK调制方式调制时终端设备的最大功率表示为P MAX21,第二波形采用QPSK调制方式调制时终端设备的最大传输功率表示为P MAX22,终端设备采用P MAX21计算得到的第二功率余量信息表示为PH 21,终端设备采用P MAX22计算得到的第二功率余量信息表示为PH 22,与第二波形对应的第一功率差表示为ΔP 20,与第二波形对应的额外功率表示为ΔP 21
具体的,在第一波形支持采用添加SS的pi/2-BPSK调制方式调制,第二波形不支持采用添加SS的pi/2-BPSK调制方式调制的场景中,在协议透明的SS的情况下(终端设备向网络设备透传数据,网络设备无法获知第一波形是否采用添加SS的pi/2-BPSK调制方式调制),对于网络设备而言,第一波形采用未添加SS的pi/2-BPSK调制方式调制还是采用添加SS的pi/2-BPSK调制方式调制是没有区别的。在这种情况 下,终端设备向网络设备发送PH 11和ΔP 10,或者该终端设备向网络设备发送PH 12和ΔP 10
若终端设备向网络设备发送PH 11和ΔP 10,则网络设备可以根据下述公式(8)或公式(9)得到第二功率余量信息PH 2
PH 2=PH 11M+ΔP C-Data-ΔP 10   (8)
PH 2=PH 11M-ΔP C-Data-ΔP 10   (9)
若终端设备向网络设备发送PH 12和ΔP 10,则网络设备可以根据下述公式(10)或公式(11)得到第二功率余量信息PH 2
PH 2=PH 12M+ΔP C-Data+ΔP 10   (10)
PH 2=PH 12M-ΔP C-Data+ΔP 10   (11)
在第一波形支持采用添加SS的pi/2-BPSK调制方式调制,第二波形不支持采用添加SS的pi/2-BPSK调制方式调制的场景中,在协议非透明的SS的情况下(网络设备能够获知第一波形是否采用添加SS的pi/2-BPSK调制方式调制),终端设备向网络设备发送PH 11和ΔP 11,或者该终端设备向网络设备发送PH 12和ΔP 11
若终端设备向网络设备发送PH 11和ΔP 11,则网络设备可以根据下述公式(12)或公式(13)得到第二功率余量信息PH 2
PH 2=PH 11M+ΔP C-Data-ΔP 11   (12)
PH 2=PH 11M-ΔP C-Data-ΔP 11   (13)
若终端设备向网络设备发送PH 12和ΔP 11,则网络设备可以根据下述公式(14)或公式(15)得到第二功率余量信息PH 2
PH 2=PH 12M+ΔP C-Data+ΔP 11   (14)
PH 2=PH 12M-ΔP C-Data+ΔP 11   (15)
由于在SS的作用下,第一波形采用添加SS的pi/2-BPSK调制方式调制后终端设备的最大传输功率得到提升,因此,网络设备根据PH 11和PH 2可更加充分的调度终端设备的资源。
具体的,在第一波形不支持采用添加SS的pi/2-BPSK调制方式调制,第二波形支持采用添加SS的pi/2-BPSK调制方式调制的场景中,在协议透明的SS的情况下,终端设备向网络设备发送PH 10和ΔP 20,或者该终端设备向网络设备发送PH 12和ΔP 20
若终端设备向网络设备发送PH 10和ΔP 20,则网络设备可以根据下述公式(16)或公式(17)得到PH 22
PH 22=PH 10M+ΔP C-Data+ΔP 20   (16)
PH 22=PH 10M-ΔP C-Data+ΔP 20   (17)
若终端设备向网络设备发送PH 12和ΔP 20,则网络设备可以根据上述公式(18)或公式(19)得到第二功率余量信息PH 22
PH 22=PH 12M+ΔP C-Data+ΔP 20   (18)
PH 22=PH 12M-ΔP C-Data+ΔP 20   (19)
在第一波形不支持采用添加SS的pi/2-BPSK调制方式调制,第二波形支持采用添加SS的pi/2-BPSK调制方式调制的场景中,在协议非透明的SS的情况下,终端设备向网络设备发送PH 10和ΔP 21,或者该终端设备向网络设备发送PH 12和ΔP 21
若终端设备向网络设备发送PH 10和ΔP 21,则网络设备可以根据下述公式(20)或 公式(21)得到PH 22
PH 22=PH 10M+ΔP C-Data+ΔP 21   (20)
PH 22=PH 10M-ΔP C-Data+ΔP 21   (21)
若终端设备向网络设备发送PH 12和ΔP 21,则网络设备可以根据下述公式(22)或公式(23)得到PH 22
PH 22=PH 12M+ΔP C-Data+ΔP 21   (22)
PH 22=PH 12M-ΔP C-Data+ΔP 21   (23)
由于在SS的作用下,第二波形采用添加SS的pi/2-BPSK调制方式调制后终端设备的最大传输功率得到提升,因此,网络设备根据PH 1和PH 22可更加充分的调度终端设备的资源。
在第一波形和第二波形均支持SS的情况下,终端设备也可以向网络设备发送与每一波形对应的第一功率差信息或与每一波形对应的额外功率差信息,也可以不再发送,本申请实施例对此不作具体限定。
本实施例提供的功率余量信息的传输方法,在终端设备确定并上报第一功率余量信息和Δ M的场景中,网络设备根据获取到的Δ M、第二功率差以及第一功率余量信息确定出第二功率余量信息,这样即可实现网络设备获取第一功率余量信息和第二功率余量信息,便于网络设备根据第一功率余量信息和第二功率余量信息实现对终端设备的资源调度。对于终端设备而言,该终端设备仅向网络设备发送第一功率余量信息,减少二者之间通信信令的开销。
现在对上述方法(2)进行说明。如图5所示,本申请实施例提供的功率余量的传输方法包括:
S500、终端设备确定第一功率余量信息和第二功率余量信息。
其中,第一功率余量信息为第一功率余量的数值的信息,终端设备确定第一功率余量信息的方法可以上述S401的描述,此处不再进行详细赘述。

一般的,功率余量差值所占的比特数小于第二功率余量的数值所占的比特数,因此,相对于第二功率余量的数值,第二功率余量的信息用功率余量差值表示可节省终端设备与网络设备之间通信信令的开销。
如果第二功率余量信息为第二功率余量的数值的信息,终端设备确定第二功率余量信息的方法与终端设备确定第一功率余量信息的方法类似,此处不再进行详细赘述。

可选的,终端设备还可以根据网络设备发送的配置信息,在预设时间段内向无线接入网设备发送第一功率余量信息和第二功率余量信息。
示例性的,若配置信息用于指示终端设备在预设时间段(如接收到配置信息后的20秒)内向网络设备发送2次功率余量信息(10秒发一次),且每次均发送第一功率余量信息和第二功率余量信息,则终端设备在接收到该配置信息后,每隔10秒向网络设备发送一次第一功率余量信息和第二功率余量信息,共发送2次。
不论是上述哪一种预设上报条件,终端设备向网络设备发送第一功率余量信息和第二功率余量信息时,均以MAC CE的形式向网络设备发送,具体可以参考上述S402的描述,此处不再进行详细赘述。
