Description

一种UE、基站中的发射功率调整的方法和装置 技术领域
本申请涉及无线通信系统中的传输方案,特别是涉及发射功率调整的方法和装置。
背景技术
未来无线通信系统的应用场景越来越多元化,不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求,在3GPP(3rd Generation Partner Project,第三代合作伙伴项目)RAN(Radio Access Network,无线接入网)#72次全会上决定对新空口技术(NR,New Radio)进行研究。
为了能够灵活适应多种不同的应用场景,未来的无线通信系统,特别是NR将可以支持多种数理结构(Numerology),多种数理结构是指多种子载波间隔,多种符号时间长度,多种CP(Cyclic Prefix,循环前缀)长度等。同时为了提高系统的性能,特别是系统的吞吐量和容量,NR将支持更加灵活的资源分配,所以在3GPP RAN1#86次会议中决定支持的上行波形包括CP-OFDM(Cyclic Prefix-Orthogonal Frequency Division Multiplexing,带循环前缀的正交频分复用)和低PAPR(Peak to Average Power Ratio,峰均比)或CM(Cubic Metric,立方度量)的波形。上行波形的PAPR或CM对上行传输的覆盖性能和功率损耗具有直接的影响,同时上行波形也会影响到接收端解码的目标SINR(Signal to Interference plus Noise Ratio,信号与干扰加噪声比)。在3GPP RAN1#86次会议中决定CP-OFDM波形和低PAPR/CM波形是互相补充的。
发明内容
在现有无线通信系统中(比如LTE),由于发射机的硬件制约和限制带外干扰的要求,上行传输的最大发射功率都是严格受到限制的。在现有协议中,上行传输的最大发射功率和上行传输的实际发射功率要同时考虑发送信号的带宽,发送信号的调制方式,所处的频带等对于上行PAPR/CM的不同影响和对带外干扰的不同的要求,从而调整终端设备的 发射功率以达到功率损耗和覆盖的较优的平衡点,提高整个系统的性能。在NR系统中,多种上行波形(CP-OFDM和其它可以降低PAPR/CM的波形)的引入使得不同波形的上行传输的PAPR/CM性能和接收端的目标SINR具有很大的差异,如果沿用现有的上行功率控制的机制,有可能会导致终端设备的功率损耗和覆盖性能下降或破坏功率损耗和覆盖性能的平衡点,使得整个系统的性能处在一个较低的水平。
针对系统内采用不同的上行波形导致的上行功率控制的问题,本申请提供了解决方案。采用本申请的解决方案,通过在上行传输功率上限的配置过程中和上行实际传输功率控制的过程中考虑不同的上行波形的影响,优化上行传输的覆盖性能和功率损耗。需要说明的是,在不冲突的情况下,本申请的UE(User Equipment,用户设备)中的实施例和实施例中的特征可以应用到基站中,反之亦然。进一步的,在不冲突的情况下,本申请的实施例和实施例中的特征可以任意相互组合。
