Description

上行功率的控制方法、装置及存储介质 技术领域
本公开涉及通信领域，尤其涉及上行功率的控制方法、装置及存储介质。

随着数据业务的快速增长，非授权频谱会承担越来越多授权载波中的数据流量，成为无线通信***中一个重要的演进方向，在3GPP RAN1Release13阶段，引入了授权辅助接入(Licensed-Assisted Access，LAA)议题讨论，对非授权频谱在下行传输中的应用达成了若干共识。

发明人在研究中发现，目前长期演进(Long Term Evolution，LTE)是部署在授权载波中运营的。但是随着数据业务的快速增长，在不久的将来，授权频谱将不能再承受下如此巨大的数据量。因此需要在非授权频谱中部署LTE，通过非授权频谱来分担授权载波中的数据流量。
另外，对于非授权频谱，也是存在很多优势的。例如，非授权频谱具有下面的特征和优势：
1、免费/低费用(不需要购买非频谱，频谱资源为零成本)。
2、准入要求低，成本低(个人、企业都可以参与部署，设备商的设备可以任意)。
3、共享资源(多个不同***都运营其中时或者同一***的不同运营商运营其中时，可以考虑一些共享资源的方式，提高频谱效率)。
4、无线接入技术多(跨不同的通信标准、协作难、网络拓扑多样)。
5、无线接入站点多(用户数量大、协作难度大、集中式管理开销大)。
6、应用多(多业务被提及可以在其中运营，例如机器到机器(Machine to machine，M2M)、车辆到车辆(Vehicle to vehicle，V2V))。
上述的基本特征，决定了非授权频谱可能是无线通信***一个重要的演进方向。在3GPP RAN1Release13阶段，引入了LAA议题讨论，对非授权频谱在下行传输中的应用达成了若干共识，在Release 14阶段，将会讨论非授权频谱在上行传输中的应用。
对于上行传输，为了保证一定的服务质量(Quality of Service，QoS)需求，在保证对上行数据准确接收的前提下尽量降低发射功率，并且应对用户的远近效应，上行功控是不可缺少的，根据LTE Release 13协议的规定， 给出了对于不同上行信道/信号的上行功控，重点包括对以下信道/信号的上行功率控制公式：
Figure PCTCN2017075896-appb-000002
PSRS,c(i)＝min{PCMAX,c(i),PSRS_OFFSET,c(m)+10log10(MSRS,c)+PO_PUSCH,c(j)+αc(j)·PLc+fc(i)}；
需要说明的是，以上信道/信号上行功率计算中各个组成部分，在LTE Release 13协议中给出了明确的解析。
对于PUSCH功控，PPUSCH,c(i)、fc(i)、ΔTF,c(i)是可以动态变化的参数，MPUSCH,c(i)对应PUSCH频域资源块(Resource Block，RB)数目，fc(i)为UL Grant中通知的功控动态调整参数，ΔTF,c(i)由MCS以及PUSCH传输内容属性决定，其他参数都是由高层信令设置的半静态配置参数。
对于SRS功控调整，只有fc(i)是可以动态变化的参数，其他参数都是由高层信令半静态配置的，而fc(i)即为PUSCH功控中的TPC，因此一旦某个子帧PUSCH的功率谱密度(Power Spectral Density，PSD)确定了，如果该子帧还发送SRS，那么该子帧SRS的PSD就也确定了，那么SRS发送功率其实无法实现独立于PUSCH发送功率的动态改变。
如果不考虑半静态上行调度，常规的上行调度为单子帧调度，即终端在下行子帧中收到一个对应自身的上行(UpLink，UL)授权Grant，该上行授权调度UL Grant指示对应后续一个上行子帧的PUSCH传输，在Release14的上行授权辅助接入UL LAA中，结合UL LAA的特点，上行多子帧调度是一种更加高效的方式，很有可能应用在UL LAA中，在上行多子帧调度中，终端在一个下行子帧会收到一个或多个UL Grant，对应后续多个连续子帧的PUSCH调度，那么只需要一次成功的上行UL LBT，终端就可以根据UL Grant的指示，连续发送多个PUSCH子帧，大大提高了上行传输效率，并减小了传输时延。但在上行多子帧调度中，如果多子帧连续传输， 期间不再进行UL LBT，那么在多个***共存时(例如LTE***与WiFi***，或多个LTE***)，如果每个子帧的PUSCH/SRS按照Release 13方式独立进行功控，可能会带来一些问题。
在LAA***发送PUSCH/SRS时，LAA***是无法了解异***节点发送PUSCH/SRS是在LAA***的PUSCH发送期间还是在SRS发送期间执行LBT CCA，假设异***的CCA门限为CCA_ED，某子帧PUSCH发设功率为P_PUSCH，该子帧SRS发送功率为P_SRS，如果P_PUSCH大于P_SRS，那么异***节点可能在PUSCH域CCA不成功，但在SRS域CCA成功，当出现这种情况时，异***会在SRS域开始占用信道，这对SRS解调本身可能不会有什么影响，但如果异***连续占用信道至下一个子帧的PUSCH域，那么异***数据传输与LAA PUSCH发送会产生冲突，造成隐藏节点问题，从而可能导致两个***的解调错误。
在本实施例中提供了一种上行功率的控制方法，图1是根据本公开实施例的上行功率的控制方法的流程图一，如图1所示，包括如下步骤：
步骤S102：在基站对终端进行连续多子帧上行调度时，基站对PUSCH功率控制中的TPC域进行配置，以使配置后的TPC域增加一个动态调整域。
这里，基站对PUSCH功率控制中的TPC域进行配置，即对TPC域进行扩充，以使扩充后的TPC域比扩充前的增加一个动态调整域。
步骤S104：基站通过配置后的TPC域控制上行调度的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率。
通过本实施例可知，对相关技术中的PUSCH功率控制公式TPC域进行扩充以增加一个动态调整域，进而对扩充后的TPC域进行调整以控制上行调度的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率，从而解决了相关技术中多***、多节点共存时出现因隐藏节点而带来干扰的问题。
需要说明的是，本实施例中涉及到的动态调整域为以下PUSCH功率控制公式中的mc(i)：
Figure PCTCN2017075896-appb-000003
其中，fc(i)为扩充前的TPC，fc(i)+mc(i)为扩充后的TPC域。
基于该公式，在本实施例的可选实施方式中为了满足上行调度的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率，需要满足：
10log10(MPUSCH,c(i))+ΔTF,c(i)+fc(i)+mc(i)＞＝10log10(MPUSCH,c(i+1))+ΔTF,c(i+1)+fc(i+1)+mc(i+1)
进而变换可以是如下(1)和(2)：
mc(i)-mc(i+1)＞＝10log10(MPUSCH,c(i+1))+ΔTF,c(i+1)+fc(i+1)-10log10(MPUSCH,c(i))-ΔTF,c(i)-fc(i)(1)或，
mc(i)+fc(i)-[mc(i+1)+fc(i+1)]＞＝10log10(MPUSCH,c(i+1))+ΔTF,c(i+1)-10log10(MPUSCH,c(i))-ΔTF,c(i)(2)。
在进行上行调度时，遵守条件(1)或(2)，可以保证上述发射功率的条件，也即上行调度的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率。
此外，在本实施例的另一个可选实施方式中，本实施例的方法还可以包括：基站只对多个连续子帧调度中的第一个子帧通知扩充后的TPC域，其中，扩充后的TPC域用于指示第一个子帧的PUSCH发射功率；或，基站对多个连续子帧调度分别通知多个扩充后的TPC域，其中，多个扩充后的TPC域分别用于指示多个连续子帧调度的PUSCH发射功率。
基于上述方式，在具体应用场景中可以是，
应用场景一：基站对终端进行连续多子帧上行调度，在对应多个被调度PUSCH子帧的UL Grant中，只发送一个TPC域，该TPC域指示连续调度的第一个PUSCH子帧的，对于其他连续调度子帧，不再通知TPC值，UE在确定其他连续调度子帧的PUSCH发射功率时，遵循连续调度的多个 子帧的PUSCH功率保持相同原则，从而可以满足上述公式(1)或(2)。
应用场景二：基站对终端进行连续多子帧上行调度，对应多个被调度PUSCH子帧的UL Grant中，会对各个子帧独立发送TPC域，终端收到对应各子帧的UL Grant后，可以计算出各个子帧的PUSCH发射功率，如果子帧n+1的PUSCH发射功率高于或者不等于子帧n，那么终端在利用子帧n+1发送PUSCH之前，需要重新做UL LBT，只有针对子帧n+1的UL LBT成功后，终端才可以根据对应UL Grant的指示，在子帧n+1上发送PUSCH。
图2是根据本公开实施例的上行功率的控制方法的流程图二，如图2所示，该方法包括：
步骤S202：终端接收基站上行调度的连续子帧，其中，连续子帧中的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率。
步骤S204：终端对连续子帧中的前一子帧的后续子帧的MCS进行调整。
通过本实施例可知，在终端接收基站上行调度的连续子帧，且连续子帧中的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率时，终端会对前一子帧的后续子帧的MCS进行调整，以避免终端自身预分配的MCS过高。
在本实施例的可选实施方式中，本实施例的步骤S204涉及到的终端对前一子帧的后续子帧的MCS进行调整的方式，可以通过如下方式来实现：
终端根据预设固定步长对前一子帧的后续子帧的MCS进行调整；或，
终端确定连续子帧中的前一子帧和前一子帧的后一子帧之间的多个PUSCH发射功率偏差值；终端根据多个偏差值确定多个步长；终端根据确定的多个步长分别调整前一子帧的后续子帧的MCS。
在本实施例的另一个可选实施方式中，本实施例中步骤S204中涉及到 的终端对前一子帧的后续子帧的MCS进行调整的方式，可以通过如下方式来实现：
在连续子帧中包括SRS时，终端根据预设固定步长对前一子帧的后续子帧的MCS进行调整；或，
在连续子帧中包括SRS时，终端确定连续子帧中的前一子帧和前一子帧的后一子帧之间的多个PUSCH发射功率偏差值，以及确定子帧中的PUSCH发射功率与SRS发射功率的偏差值；终端根据多个偏差值确定多个步长；终端根据确定的多个步长分别调整前一子帧的后续子帧的MCS。
由上述对MSC进行调整的方式可知，在具体应用场景中可以是：基站对终端进行连续多子帧上行调度，多个连续子帧为n、n+1、n+2；子帧n上的前13个OFDM符号用于PUSCH传输，最后一个符号用于SRS传输，子帧n+1、子帧n+2均为PUSCH传输。终端根据UL Grant的指示，确定子帧n的PUSCH发射功率P1_PUSCH，子帧n的SRS发射功率P1_SRS，子帧n+1的PUSCH发射功率P2_PUSCH，如果确定后的发射功率满足P1_SRS<P1_PUSCH或P2_PUSCH<P1_PUSCH，那么终端可以了解，子帧n+1上可能存在新的共存节点，那么终端需要对之前UL Grant中已经对子帧n+1分配的MCS进行微调，调整趋势为降低的趋势，具体调整时，可以按照某个固定或非固定步长来调整，如果是固定步长，那么无论P1_SRS与P1_PUSCH、P2_PUSCH与P1_PUSCH偏差多大，都按照该步长来调整子帧n+1真实发送PUSCH的MCS；如果是非固定步长，那么根据P1_SRS与P1_PUSCH、P2_PUSCH与P1_PUSCH的偏差程度，来从一个步长调整范围中选择适合的步长，选择原则是：功率偏差越大，即后者比前者大得越多，那么MCS调整步长就应该越大，反之越小，最后，终端按照调整后的MCS来发送子帧n+1的PUSCH。
需要说明的是，在连续子帧中包括SRS时，本实施例的方法还可以包 括：终端调整SRS的发射功率与PUSCH发射功率一致。在具体应用场景中，该方式可以是：调度站点对终端进行连续多子帧上行调度，该连续调度子帧中子帧n上的前13个OFDM符号用于PUSCH传输，最后一个符号用于SRS传输，子帧n+1、子帧n+2均为PUSCH传输。终端根据对应子帧n的UL Grant中通知的TPC值，确定子帧n上的PUSCH发射功率和SRS发射功率，如果两者发射功率不等，则终端调整SRS发射功率，调整至SRS发射功率与PUSCH发射功率相同。
在一实施例中，在连续子帧中包括SRS且终端在非授权载波上发送SRS时，本实施例的方法还包括：终端配置连续子帧的最后一个子帧为SRS的发送子帧。
其中，在具体应用场景中可以是，终端在非授权载波上发送SRS时，按照非周期SRS的配置方法和触发原则来配置SRS发送子帧，调度站点对某终端连续调度了子帧n、子帧n+1、子帧n+2，调度站点在UL Grant中指示在子帧n上需要该终端发送非周期SRS(子帧n满足RRC信令通知的SRS配置周期以及子帧偏置)，终端收到该非周期SRS触发指令后，会把SRS发送子帧自行调整为本次连续调度的最后一个子帧，即子帧n+2，从而保证SRS的发送功率不受子帧n、子帧n+1的上行信道发射功率的影响，从而该终端可以独立确定子帧n+2上SRS的发射功率。调度站点也可以在UL Grant中直接指示该终端在子帧n+2上发送非周期SRS，而非在子帧n上发送非周期SRS。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如只读 存储器(Read Only Memory，ROM)/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。

下面结合本公开的可选实施例对本公开进行举例说明；
本可选实施例提供了一种上行连续子帧调度下的信道/信号功率控制方法，图5是根据本公开可选实施例的上行多子帧调度示意图，如图5所示，假设SF#n的PUSCH发射功率为P1_PUSCH，SF#n的SRS发射功率为P1_SRS，SF#n+1的PUSCH发射功率为P2_PUSCH。注意，SF#n为连续子帧调度的第一个子帧，需要说明的是，在本可选实施例中假设P1_PUSCH本身不会造成隐藏节点问题。
下面将从两个角度出发对本可选实施例进行详细说明：1)对异***的影响，即是否会出现隐藏节点问题而影响异***性能；2)对自身MCS准确性的影响。
Case 1：P1_PUSCH>＝P1_SRS>＝P2_PUSCH；
其中，异***在SF#n的SRS域可能CCA成功，从角度1)出发，SF#n+1不会对异***出现隐藏节点问题。从角度2)出发，该节点在SF#n+1可能出现信道质量恶化，从而UL Grant分配的MCS过于乐观。
Case 2：P1_SRS>＝P1_PUSCH>＝P2_PUSCH；
其中，异***在SF#n+1可能CCA成功，从角度1)出发，SF#n+1不会对异***出现隐藏节点问题。从角度2)出发，该节点在SF#n+1可能出现信道质量恶化，从而UL Grant分配的MCS过于乐观。
Case 3：P2_PUSCH>＝P1_PUSCH>＝P1_SRS；
其中，异***在SF#n的SRS域可能CCA成功，从角度1)出发，如果异***连续占用信道，则SF#n+1会对异***出现隐藏节点问题。从角度2)出发，该节点在SF#n+1可能出现信道质量恶化，从而UL Grant分配的MCS过于乐观。
Case 4：P1_PUSCH>＝P2_PUSCH>＝P1_SRS；
其中，异***在SF#n的SRS域或SF#n+1都可能CCA成功，从角度 1)出发，SF#n+1不会对异***出现隐藏节点问题。从角度2)出发，该节点在SF#n+1可能出现信道质量恶化，从而UL Grant分配的MCS过于乐观。
Case 5：P1_SRS>＝P2_PUSCH>＝P1_PUSCH；
其中，异***在SF#n的SRS域、在SF#n+1都不会CCA成功，但对于在SF#n的SRS域之前CCA成功的异***，如果连续占用至SF#n+1域，那么从角度1)出发，SF#n+1会对异***出现隐藏节点问题。从角度2)出发，对该节点自身没什么影响。
Case 6：P2_PUSCH>＝P1_SRS>＝P1_PUSCH；
其中，异***在SF#n的SRS域、在SF#n+1都不会CCA成功，但对于在SF#n的SRS域之前CCA成功的异***，如果连续占用至SF#n+1域，那么从角度1)出发，SF#n+1会对异***出现隐藏节点问题。从角度2)出发，对该节点自身没什么影响。
由上述6种情况的分析可知，从角度1)出发，即为了在SF#n+1不对异***出现隐藏节点问题，应该满足：P2_PUSCH<＝P1_PUSCH。
而从角度2)出发，为了避免节点自身预分配的MCS过高，一旦出现P1_SRS<P1_PUSCH或P2_PUSCH<P1_PUSCH，则需要UE应该自适应调整SF#n+1上预分配的MCS。
下面结合本公开可选实施例的具体实施例对本公开进行详细说明，需要说明的是，下面实施例中提到的多子帧调度UL Grant，对于某个终端，可以是一个UL Grant对应多个被调度的PUSCH子帧，也可以是多个UL Grant分别对应多个被调度的PUSCH子帧。无论是一个UL Grant对应多个PUSCH子帧还是多个UL Grant对应多个PUSCH子帧，一个UL Grant中可能会包含频域资源分配指示、MCS指示、TPC指示等PUSCH传输属性指示中的多种指示。
实施例1：
在多子帧调度下，适当修改PUSCH的功控方法为：
Figure PCTCN2017075896-appb-000005
在PUSCH功控中，增加了mc(i)，该值表示因多子帧调度而对PUSCH进行的额外PSD调整，对于单子帧调度情况或多子帧调度的第一个子帧，mc(i)＝0。
在mc(i)不为0的情况下，为了满足P2_PUSCH<＝P1_PUSCH，则有：
10log10(MPUSCH,c(i))+ΔTF,c(i)+fc(i)+mc(i)＞＝10log10(MPUSCH,c(i+1))+ΔTF,c(i+1)+fc(i+1)+mc(i+1)，因此，
mc(i)-mc(i+1)＞＝10log10(MPUSCH,c(i+1))+ΔTF,c(i+1)+fc(i+1)-10log10(MPUSCH,c(i))-ΔTF,c(i)-fc(i)(1)或，
mc(i)+fc(i)-[mc(i+1)+fc(i+1)]＞＝10log10(MPUSCH,c(i+1))+ΔTF,c(i+1)-10log10(MPUSCH,c(i))-ΔTF,c(i)(2)。
需要说明的是，上述(1)与(2)是完全等效的。
调度站点对终端进行上行调度时，应该遵守上述条件(1)或(2)，从而保证P2_PUSCH<＝P1_PUSCH。在具体应用场景可以有以下几种方式：
方式1：把mc(i)与fc(i)融合得到新的TPC，即调度站点除了在UL Grant中通知终端对应调度子帧的TPC外，可以不做其他额外通知，仅仅是调度站点在计算对应各连续子帧的TPC时，满足条件(2)。
方式2：调度站点除了在UL Grant中通知终端对应调度子帧的TPC外，还需要额外通知mc(i)，并且对于各连续子帧的mc(i)，应该满足(1)。
实施例2：
调度站点对终端进行连续多子帧上行调度，在对应多个被调度PUSCH子帧的UL Grant中，只发送一个TPC域，该TPC域指示连续调度的第一个PUSCH子帧的fc(i)，对于其他连续调度子帧，不再通知TPC值，UE在 确定其他连续调度子帧的PUSCH发射功率时，遵循连续调度的多个子帧的PUSCH功率保持相同原则，从而可以满足(1)或(2)。
实施例3：
调度站点对终端进行连续多子帧上行调度，对应多个被调度PUSCH子帧的UL Grant中，会对各个子帧独立发送TPC域，终端收到对应各子帧的UL Grant后，可以计算出各个子帧的PUSCH发射功率，如果子帧n+1的PUSCH发射功率高于或者不等于子帧n，那么终端在利用子帧n+1发送PUSCH之前，需要重新做UL LBT，只有针对子帧n+1的UL LBT成功后，终端才可以根据对应UL Grant的指示，在子帧n+1上发送PUSCH。
实施例4：
调度站点对终端进行连续多子帧上行调度，连续调度子帧如图3所示，子帧n上的前13个OFDM符号用于PUSCH传输，最后一个符号用于SRS传输，子帧n+1、子帧n+2均为PUSCH传输。终端根据对应子帧n的UL Grant中通知的TPC值，确定子帧n上的PUSCH发射功率和SRS发射功率，如果两者发射功率不等，则终端调整SRS发射功率，调整至SRS发射功率与PUSCH发射功率相同。
实施例5：
调度站点对终端进行连续多子帧上行调度，连续调度子帧如图5所示，子帧n上的前13个OFDM符号用于PUSCH传输，最后一个符号用于SRS传输，子帧n+1、子帧n+2均为PUSCH传输。终端根据UL Grant的指示，确定子帧n的PUSCH发射功率P1_PUSCH，子帧n的SRS发射功率P1_SRS，子帧n+1的PUSCH发射功率P2_PUSCH，如果确定后的发射功率满足P1_SRS<P1_PUSCH或P2_PUSCH<P1_PUSCH，那么终端可以了解，子帧n+1上可能存在新的共存节点，那么终端需要对之前UL Grant中已经对子帧n+1分配的MCS进行微调，调整趋势为降低的趋势，具体调整 时，可以按照某个固定或非固定步长来调整，如果是固定步长，那么无论P1_SRS与P1_PUSCH、P2_PUSCH与P1_PUSCH偏差多大，都按照该步长来调整子帧n+1真实发送PUSCH的MCS；如果是非固定步长，那么根据P1_SRS与P1_PUSCH、P2_PUSCH与P1_PUSCH的偏差程度，来从一个步长调整范围中选择适合的步长，选择原则是：功率偏差越大，即后者比前者大得越多，那么MCS调整步长就应该越大，反之越小，最后，终端按照调整后的MCS来发送子帧n+1的PUSCH。
实施例6：
调度站点对终端进行连续多子帧上行调度，在一个下行子帧中终端收到了针对后续上行子帧n、子帧n+1、子帧n+2的UL Grant，在UL Grant中基站指示了针对子帧n的TPC域，可以是累积方式或者绝对方式，针对子帧n+1的TPC域，基站指示采用在子帧n基础上累积的方式，并且累积TPC值为一个固定值，例如值为0dB或-1dB，针对子帧n+2，也采用同子帧n+1相同的累积TPC特定值指示方法。该实施例中，针对子帧n+1和子帧n+2的TPC域，也可以称之为相对前一子帧的上行发射功率偏置值，即基站根据基站通知的针对子帧n的TPC值，计算出子帧n的上行发射功率后，在计算子帧n+1的上行发射功率时，计算方法为：子帧n+1的上行发射功率＝子帧n的上行发射功率+功率偏置值1，在计算子帧n+2的上行发射功率时，计算方法为：子帧n+2的上行发射功率＝子帧n+1的上行发射功率+功率偏置值2，其中功率偏置值1和功率偏置值2分别为子帧n+1、子帧n+2相对前一子帧的功率偏置值，或者分别为子帧n+1、子帧n+2相对子帧n的功率偏置值，这两个值可以相同，例如都配置为0dB，也可以不同。
实施例7：
本实施例为一种包含多用户频分复用的情况，图6是根据本公开可选 实施例的多用户频分复用上行多子帧调度示意图，如图6所示，终端1、终端2、终端3都是调度站点覆盖小区内的用户，调度站点对终端1连续调度了上行子帧n、子帧n+1，调度站点对终端2连续调度了上行子帧n-1、子帧n，调度站点对终端3连续调度了上行子帧n+1、子帧n+2，即可以看出来，在子帧n上，终端1和终端2频分复用上行带宽，在子帧n+1上，终端1和终端3频分复用上行带宽。调度站点在对终端1、终端2确定TPC值时，需要满足：
Figure PCTCN2017075896-appb-000006
Figure PCTCN2017075896-appb-000007
Figure PCTCN2017075896-appb-000008
其中，RBall表示上行***带宽，以RB数目衡量；
Figure PCTCN2017075896-appb-000009
表示终端x在子帧y上被调度的上行带宽，以RB数目衡量；
Figure PCTCN2017075896-appb-000010
表示终端x在子帧y上所传输上行信道/信号的功率谱密度，即单位RB上的功率。
即站点根据每个子帧调度的各用户RB数目，确定对各用户功率谱密度的需求，保证该用户调度的一个上行burst，后一个子帧总上行发射功率不超过前一个子帧总上行发射功率，在此原则基础上，基站确定被调度用户各个子帧的TPC值，并把该值通知给对应终端。
实施例8：
终端在非授权载波上发送SRS时，按照非周期SRS的配置方法和触发原则来配置SRS发送子帧，调度站点对某终端连续调度了子帧n、子帧n+1、子帧n+2，调度站点在UL Grant中指示在子帧n上需要该终端发送非周期SRS(子帧n满足RRC信令通知的SRS配置周期以及子帧偏置)，终端收到该非周期SRS触发指令后，会把SRS发送子帧自行调整为本次连续调度的最后一个子帧，即子帧n+2，从而保证SRS的发送功率不受子帧n、子帧n+1的上行信道发射功率的影响，从而该终端可以独立确定子帧n+2上SRS的发射功率。调度站点也可以在UL Grant中直接指示该终端在子帧n+2上 发送非周期SRS，而非在子帧n上发送非周期SRS。
本公开的实施例还提供了一种存储介质。在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：
步骤S1：在基站对终端进行连续多子帧上行调度时，基站对物理上行共享信道功率控制中的TPC域进行配置，以使配置后的TPC域TPC增加一个动态调整域。
步骤S2：基站通过配置后的TPC域控制上行调度的前一子帧的PUSCH发射功率不小于前一子帧的后续子帧的PUSCH发射功率。

步骤S2：终端对连续子帧中的前一子帧的后续子帧的MCS进行调整。
在一实施例中，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
显然，本领域的技术人员应该明白，上述的本公开的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，在一实施例中，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本公开不限制于任何特定的硬件和软件结合。
本公开实施例中，如果以软件功能模块的形式实现上述上行功率的控 制方法，并作为独立的产品销售或使用时，也可以存储在一个计算机可读取存储介质中。基于这样的理解，本公开实施例的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机、服务器、或者网络设备等)执行本公开各个实施例所述方法的全部或部分。而前述的存储介质包括：U盘、移动硬盘、ROM、磁碟或者光盘等各种可以存储程序代码的介质。这样，本公开实施例不限制于任何特定的硬件和软件结合。
相应地，本公开实施例还提供一种计算机存储介质，该计算机存储介质中存储有计算机程序，该计算机程序用于执行本公开实施例的上述上行功率的控制方法。
以上所述仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
