技术领域
本发明涉及通信领域，具体而言，涉及一种发送功率的确定、信令配置方法及装置、终端、基站。
背景技术
在长期演进(LTE，Long Term Evolution)中，物理下行控制信道(PDCCH，Physical Downlink Control Channel)用于承载上、下行调度信息，以及上行功率控制信息。下行控制信息(DCI，Downlink Control Information)格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3、3A等，后面演进至高级长期演进(LTE-A，LTE-Advanced)版本12(LTE-A Release 12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。演进型基站(eNB，e-Node-B)可以通过下行控制信息配置用户设备(UE，User Equipment)，或者第二通信节点接收高层(higher layers)的配置，也称为通过高层信令来配置UE。
无线系统中的上行功率控制是非常重要的，通过上行功控，可以使得小区中的UE既保证上行所发送数据的质量，又尽可能减少对系统中其他用户的干扰，延长UE电池的使用时间。
LTE/LTE-A系统中，同小区内不同用户之间的上行数据是正交的，因 此，LTE系统采用慢速的上行功率控制，主要考虑通过功率控制来使得上行传输适应不同的无线传输环境，包括路损、阴影衰落等。LTE功率控制的对象包括物理上行链路控制信道(PUCCH，Physical Uplink Control CHannel)、物理上行链路共享信道(PUSCH，Physical Uplink Shared Channel)、信道探测参考信号(SRS，Sounding Reference Signal)等。虽然这些上行信号的数据速率和重要性各自不同，其具体功控方法和参数也不尽相同。但其原理都是基本相同的，可以归纳为：
UE发射的功率谱密度(即每资源块(RB，Resource Block)上的功率)＝开环工控点+动态的功率偏移。其中，开环工控点＝目标功率P0+开环的路损补偿α×(PL)。目标功率P0又分为小区目标功率和UE特定的目标功率两部分。
开环的路损PL基于UE对于下行的路损估计。UE通过测量下行参考信号接收功率(RSRP，Reference Signal Received Power)，并与已知的RS信号功率进行相减，从而进行路损估计。
对于PUSCH和SRS，eNodeB通过参数路损补偿因子α来决定路损在UE的上行功率控制中的权重。比如说，对于处于小区边缘的UE，如果其发送功率过高，会对别的小区造成干扰，从而降低整个系统的容量。对于PUCCH来说，由于不同的PUCCH用户是码分复用的，α取值为1，可以更好地控制不同PUCCH用户之间的干扰。
动态的功率偏移包含两个部分，基于调制编码方式(MCS，Modulation Coding Scheme)的功率调整△TF和闭环的功率控制。基于MCS的功率调整可以使得UE根据选定的MCS来动态地调整相应的发射功率谱密度。闭环的功率控制是指UE通过PDCCH中的传输功率控制(TPC，Transmitting Power Command)传输功率命令来对UE的发射功率进行调整。可以分为累积调整和绝对值调整两种方式。累积调整方式适用于PUSCH，PUCCH和 SRS，绝对值调整方式只适用于PUSCH。这两种不同的调整方式之间的转换是半静态的，eNB通过专用RRC无线资源控制(RRC，Radio Resource Control)信令指示UE采用累积方式还是绝对值方式。
累积方式是指当前功率调整值是在上次功率调整的数值上增加/减少一个TPC中指示的调整步长，累积方式是UE缺省使用的调整方式。LTE中累积方式的TPC可以有两套不同的调整步长，第一套步长为(-1，0，1，3)dB，对于PUSCH，由DCI format 0/3指示；对于PUCCH，由DCI format 1/1A/1B/1D/2/2A/3指示。第二套步长为(-1，1)，由DCI format 3a指示(适用于PUCCH和PUSCH)。
绝对值方式是指直接使用TPC中指示的功率调整数值，只适用于PUSCH。此时，eNodeB需要通过RRC信令显式地关闭累积方式地功率调整方式。当采用绝对值方式时，TPC数值为(-4，-1，1，4)dB，由DCI format 0/3指示，其功率调整地范围可达8db,适用于UE不连续的上行传输，可以使得eNodeB一步调整UE的发射功率至期望值。
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30～300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是：相对低频信号，高频信号在空间的衰落非常大，虽然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于其波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，相关技术中的研究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最 终的波束。
在新的无线接入技术(NRAT，New Radio Access Technology)的研究中，高频通信系统除了第一通信节点会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落，第二通信节点同样也会配置大量的天线形成发送波束，第一通信节点侧也会选择合适的接收波束以匹配接收上行信号；其中，发送波束和接收波束可以用参考信号索引指示的方式、空域发送滤波器、空间准共址来表示。在相关技术的研究中，已经确定采用波束专有的上行功控机制，但如何实现灵活有效的配置，以适应NRAT的多种应用场景，是目前上行功控标准化中待解决的问题。
针对相关技术中的上述技术问题，目前尚未提出有效的解决方案。
