具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)或全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统、5G系统，或者说新无线(New Radio,NR)系统。
在本申请实施例中，终端设备可以包括但不限于移动台(Mobile Station，简称为“MS”)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本申请实施例中，网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的系统中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，简称为“eNB”或“eNodeB”)，在第三代(3rd Generation，简称为“3G”)网络中，称为节点B(Node B)等等。
LTE系统上行传输仅支持离散傅里叶变换扩频的正交频分复用(Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing，简称为 “DFT-S-OFDM”)多址方式，网络侧仅需要配置一套上行功率控制参数用于上行传输，但是目前5G系统中的上行传输中引入了两种上行多址方式(或称为“上行波形”)：DFT-S-OFDM多址方式和循环前缀(Cyclic Prefix，简称为“CP”)-OFDM多址方式。前者只能用于上行单层传输，后者可以用于上行单层或多层传输。终端设备使用哪一种多址方式可以由网络侧根据终端的上行信道质量配置。通常DFT-S-OFDM多址方式的信道传输覆盖性能更好，但是频谱效率较低。而CP-OFDM多址方式的频谱效率较高，但由于其峰均比(Peak to Average Power Ratio，简称为“PAPR”)较高，因此其覆盖性能较差。当终端设备使用不同的多址方式进行上行信号的传输时，由于覆盖范围不同，需要的上行发送功率也不同，采用LTE系统中的控制上行功率方法无法满足不同上行多址方式的需求。
因此，本申请实施例提供一种控制上行功率的方法，使得终端设备能够采用独立的上行功率控制进程计算每种上行多址方式对应的上行发送功率，能够灵活调整上行发送功率，满足不同上行多址方式的需求。
需要说明的是，本申请实施例中，上行传输指的是终端设备向网络设备发送信号的过程，下行传输指的是网络设备向终端设备发送信号的过程。
图1示出了根据本申请实施例的控制上行功率的方法。如图1所示，方法100包括：
S110，终端设备接收网络设备发送的上行功率控制信息；
S120，所述终端设备根据所述上行功率控制信息，确定目标上行多址方式对应的目标功率控制参数；
S130，所述终端设备根据所述目标功率控制参数，确定采用所述目标上行多址方式发送目标上行信号时的目标发送功率。
根据本申请实施例的控制上行功率方法，终端设备根据接收到的网络设备发送的上行功率控制信息，确定目标上行多址方式对应的目标功率控制参数。由此当终端设备使用不同的上行多址方式进行上行信号传输时，可以采用独立的上行功率控制进程确定上行多址方式对应的上行发送功率，能够灵活调整上行发送功率，满足不同上行多址方式的需求，适用于支持多种上行多址方式的通信系统。
需要说明的是，终端设备根据目标功率控制参数确定了采用目标上行多址方式发送目标上行信号时的目标发送功率后，可以采用目标上行多址方式 和目标发送功率在当前时刻传输目标上行信号，也可以不采用目标上行多址方式在当前时刻传输目标上行信号。当终端设备不采用目标上行多址方式在当前时刻传输目标上行信号时，终端设备可以存储确定的目标发送功率，在以后采用目标上行多址方式实际传输目标上行信号时，采用确定的这个目标发送功率传输所述目标上行传信号。
并且，目标上行多址方式可以为终端设备发送目标上行信号可能采用的多种候选上行多址方式中的一种候选上行多址方式，在这种情况下，终端设备根据网络设备发送的上行功率控制信息确定每一种候选上行多址方式对应的功率控制参数。或者目标上行多址方式为终端设备发送目标上行信号需要采用的上行多址方式，在这种情况下，终端设备可以根据网络侧配置的多址方式指示信息确定目标上行多址方式。例如，目标上行多址方式可以通过信令显示指示，例如，无线资源控制(Radio Resource Control，简称为“RRC”消息或下行控制信息(Downlink Control Information，简称为“DCI”)。或者目标上行多址方式可以通过其他信息隐性指示，例如不同的DCI格式对应不同的上行多址方式。
在本申请实施例中，可选地，目标上行多址方式为多种上行多址方式中的一种上行多址方式。例如，目标上行多址方式为下列多址方式中的一种：离散傅里叶变换扩频的正交频分复用(Fourier Transform Spread Orthogonal Frequency Division Multiplexing，简称为“DFT-S-OFDM”)、循环前缀(Cyclic Prefix，简称为“CP”)-OFDM、单载波频分多址接入(Single-carrier Frequency-Division Multiple Access，简称为“SC-FDMA”)和正交频分多址接入(Orthogonal Frequency Division Multiple Access，简称为“OFDMA”)。
在本申请实施例中，可选地，上行功率控制信息中包括开环功率控制信息，开环功率控制信息中包括多种上行多址方式对应的开环功率控制参数，多种上行多址方式包括目标上行多址方式。终端设备根据开环功率控制信息确定开环功率参数中与目标上行多址方式中对应的目标开环功率控制参数。
可选地，作为一个例子，所述目标开环功率控制参数包括下列参数中的至少一种：上行目标接收功率、路损因子和探测参考信号(Sounding Reference Signal，简称为“SRS”)功率调整值。
可选地，作为一个例子，终端设备接收网络设备通过RRC消息发送的开环功率控制信息。网络设备通过开环功率控制信息为不同的上行多址方式 分别配置各自的开环功率控制参数。
具体地，在一些实施例中，网络设备可以为一种上行多址方式配置完整的开环功率控制参数，为其他上相多址方式配置相对于这一种上行多址方式对应的开环功率控制参数的偏移值，由此能够节省下行信令的开销。例如，网络设备配置DFT-S-OFDM对应的上行目标接收功率为-60dBm，配置CP-OFDM对应的上行目标接收功率相对于DFT-S-OFDM对应的上行目标接收功率的偏移值为10dBm。
或者，在一些实施例中，网络设备为每一种上行多种方式配置完整的开环功率控制参数。例如网络设备配置DFT-S-OFDM对应的上行目标接收功率为-60dBm，路损因子为1，配置CP-OFDM对应的上行目标接收功率为20dBm，路损因子为2。当终端设备确定采用其中的一种上行多址方式发送目标上行信号时，根据确定的上行多址方式对应的这些开环功率控制参数来计算目标上行信号的发送功率。
在本申请实施例中，可选地，上行功率控制信息中包括功率调整指示信息，终端设备根据功率调整指示信息和预设对应关系，确定与目标上行多址方式对应的目标闭环功率调整值，预设对应关系为功率调整指示信息与闭环功率调整值的对应关系。
可选地，在一些实施例中，终端设备接收网络设备发送的DCI，所述DCI中包括功率调整指示信息。并且，这里的DCI可以是用于调度目标上行信号传输的DCI，也可以是专门用于承载功率调整指示信息的DCI，此时DCI不用于调度目标上行信号的传输。
可选地，作为一个例子，上述的预设对应关系可以是由终端设备与网络设备预先预定好的，也可以是网络设备通过指示信息为终端设备配置的。预设对应关系可以入表1所示。需要说明的是，表1仅仅是给出了一种预设对应关系的例子，而不是对预设对应关系的限定。
表1
Figure PCTCN2016109652-appb-000001
Figure PCTCN2016109652-appb-000002
在本申请实施例中，对于不同的上行多址方式，功率调整指示信息中同一指示域指示的闭环功率调整值的取值可能不同。由此终端设备需要根据目标上行多址方式从预设对应关系中确定目标对应关系，之后根据功率调整信息和目标对应关系，确定目标闭环功率调整值。对于不同的上行多址方式，功率调整指示信息与闭环功率调整值的对应关系可以由终端设备与网络设备预先约定好，也可以通过网络设备通过指示信息为终端设备配置。例如，表2示出了功率调整指示信息与闭环功率调整值的另一种对应关系。
表2
Figure PCTCN2016109652-appb-000003
在本申请实施例中，可选地，目标闭环功率调整值可以是基于开环功率进行调整的绝对值，也可以是基于前一次发送功率进行调整的累加值。网络设备可以通过信令配置终端设备所述目标闭环功率调整值是基于开环功率进行调整的绝地值还是基于前一次发送功率进行调整的累加值。
具体地，在一些实施例中，目标闭环功率调整值为目标发送功率相对于第一发射功率的调整值，第一发送功率为终端设备前一次发送与目标上行信号类型相同的上行信号时所用的发送功率。例如，目标闭环功率调整值可以是终端设备发送物理上行共享信道(Physical Uplink Shared Channel，简称为“PUSCH”)的发送功率相对于终端设备上一次发送PUSCH的发送功率的调整值。
或者，目标闭环功率调整值为目标发送功率相对于第二发送功率的调整值，第二发送功率为终端设备前一次采用目标上行多址方式发送与目标上行信号类型相同的上行信号时所用的发送功率。例如，目标闭环功率调整值为终端设备采用DFT-S-OFDM发送PUSCH的发送功率相对于终端设备上一次采用DFT-S-OFDM发送PUSCH的发送功率的调整值。
或者，目标闭环功率调整值为目标发送功率相对于第三发送功率的调整值，第三发送功率为终端设备最近一次确定的与目标信号类型相同的上行信号的发送功率。例如，目标闭环功率调整值为终端设备发送PUSCH的发送功率相对于最近计算的PUSCH的发送功率的调整值。这里并不意味着终端设备在更新发送功率时需要实际发送PUSCH，但终端设备会存储最近计算的PUSCH的发送功率用于后续的PUSCH的传输。
或者，目标闭环功率调整值为目标发送功率相对于第四发送功率的调整值，第四发送功率为终端设备最近一次确定的采用目标上行多址方式发送且目标上行信号类型相同的上行信号的发送功率。例如，目标功率调整值为终端设备采用DFT-S-OFDM发送PUSCH的发送功率相对于最近一次计算得到(或最近一次更新)的采用DFT-S-OFDM发送PUSCH的发送功率的调整值。这里并不意味着终端设备这里并不意味着终端设备在更新发送功率时需要实际发送PUSCH，但终端设备会存储最近计算的PUSCH的发送功率用于后续的PUSCH的传输。
或者，目标功率调整值为目标发送功率相对于第五发送功率的调整值，第五发送功率为终端设备根据目标上行多址方式对应的开环功率控制参数确定的目标上行信号的发送功率。这里的开环功率控制参数可以是网络设备通过高层信令配置的参数，例如目标接收功率和路损因子。终端设备可以根据公式(1)和开环功率控制参数计算发送功率。
PPUSCH(i)＝10log10(MPUSCH(i))+PO_PUSCH(j)+α(j)·PL+ΔTF(i)      (1)
其中，MPUSCH(i)为上行传输带宽，PO_PUSCH(j)为目标接收功率，α(j)为路损因子，PL为下行路损，ΔTF(i)为调制与编码策略(Modulation and Coding Scheme，简称为“MCS”)相关的调整值。
在上述实施例中，终端设备可以根据网络设备通过高层信令为不同的上行多址方式分别配置的开环功率控制参数，确定目标上行多址方式对应的目标开环功率控制参数。并根据网络设备通过DCI携带的功率调整指示信息，确定与目标上行多址方式对应的目标闭环功率调整值。之后终端设备根据目标开环功率控制参数、目标闭环功率调整值以及预设的发送功率计算方法或公式，计算目标发送功率。
进一步地，在终端设备确定目标发送功率之后，如图2所示，方法100还包括：
S130，终端设备采用目标上行多址方式和目标发送功率，向网络设备发送目标上行信号。
在上述所有实施例中，可选地，目标上行信号为下列信号中的一种：PUSCH、物理上行控制信道(Physical Uplink Control Channel，简称为“PUCCH”)、SRS和解调参考信号(De Modulation Reference Signal，简称为“DMRS”)。
以上结合图1和图2从终端设备侧详细描述根据本申请实施例的控制上行功率的方法，下面将结合图3和图4从网络设备侧详细描述根据本申请实施例的控制上行功率的方法。应理解，网络设备侧描述的网络设备与终端设备的交互与终端设备侧的描述相同，为避免重复，适当省略相关描述。
