    • A receiver circuit receives a signal including a first reference signal from a first antenna port that is allocated to the UE. The receiver circuit includes a descrambling and despreading unit that despreads and descrambles the signal using a spreading code of the first antenna port and a scrambling sequence assigned to the UE to generate a first antenna port signal. The descrambling and despreading unit despreads and descrambles the signal using a spreading code of a second antenna port and the scrambling sequence assigned to the UE, wherein the second antenna port is unallocated to the UE to generate a second antenna port signal. A channel estimator generates a channel estimate of the first antenna port based on the first antenna port signal. An estimation unit estimates an interference and noise covariance measure based on the first antenna port signal, the channel estimate and the second antenna port signal.
    • 接收机电路接收包括分配给UE的第一天线端口的第一参考信号的信号。 接收机电路包括解扰和解扩单元,其使用第一天线端口的扩展码对解调和解扰信号,以及分配给UE的加扰序列以产生第一天线端口信号。 解扰和解扩单元使用第二天线端口的扩展码和分配给UE的加扰序列对信号进行解扩和解扰,其中第二天线端口未分配给UE以产生第二天线端口信号。 信道估计器基于第一天线端口信号产生第一天线端口的信道估计。 估计单元基于第一天线端口信号,信道估计和第二天线端口信号估计干扰和噪声协方差测量。
