提出基站解调性能要求的目标是估计实际网络如何运行,验证基站不同的损害因素,这些损害因素会对网络性能产生影响。这些影响因素包括RF和基带损害因素、接收机EVM(误差矢量幅度)时域和频域跟踪、频率估计等。对物理上行链路共享信道(PUSCH)、物理上行链路控制信道(PUCCH)和物理随机接入信道(PRACH)的基站解调性能要求进行了描述,给出了各类信道的基站测试集。
The goal of the base station demodulation performance requirement is to estimate how the actual network operates and to verify the different impairments of the base station, which will affect the network performance. These factors include RF and baseband impairments, receiver EVM (error vector magnitude) time and frequency domain tracking, frequency estimation, and more. Base station demodulation performance requirements for physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH) and physical random access channel (PRACH) are described, and base station test sets for various types of channels are given.
