    摘要: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for SRS data transmission. In example embodiments, a method is provided. According to the method, an apparatus forwards, during a first period, first SRS data received from a terminal device to a further apparatus. The further apparatus determines, based on the first SRS data, compression information for compressing SRS data, and transmits the compression information to the apparatus. Thereby, the apparatus compresses, during a second period, second SRS data received from the terminal device based on the compression information, and transmits, during the second period, the compressed second SRS data to the further apparatus. In this way, the SRS data can be effectively compressed, thus reducing the latency of the SRS data transmission.

    摘要: 提供了一种DMRS的配置方法,该方法包括:网络设备向终端设备发送第一调度信息,终端设备根据第一调度信息确定第一时间单元的传输是否满足第一条件,当第一时间单元对应的第一调度信息与第二时间单元对应的第二调度信息相同时,第一时间单元上的传输与第二时间单元上的传输满足第一条件,即保持相同的发送功率、相同的预编码、相同的天线端口和相同的频域资源中的至少一项。通过第一调度信息限制了时间单元上的传输,使得终端设备或者网络设备在接收数据时才能够对满足第一条件且满足相位连续性的时间单元上的DMRS进行合并,实现更准确的信道估计,改善对上行传输数据的解调性能。

    摘要: Embodiments of an apparatus and method for iterative correction in wireless communication are disclosed. In an example, a reference signal and an initial data signal are received by an apparatus. The apparatus performs initial channel estimation and interference and noise estimation and initially demodulates the initial data signal. The apparatus then iteratively produces a hard decision, regenerates a regenerated data signal, calculates interference and noise covariance, and obtains a corrected demodulated data signal until a quality is satisfied or a number of iterations have occurred. The apparatus further decodes the demodulated data signal.

    摘要: The present invention is a multilevel equalizer bearing dual equalizer units for performing equalization operations before and after the combination of multipath signals. The Pre-Combining Equalizer functions on the basis of the Least Mean Square (LMS) Criterion and the Linear Predictive Filtering method by use of the Bit Error Rate (BER) code of the final output, which minimizes the errors caused by multipath delays and Inter-Symbol Interferences (ISI). The post-combining equalizer effectively reduces the errors that are induced as a result of imperfect combining. Such a system can suitably function by the employment of Forward Error Correction (FEC) having lower code rate that can be effective for obtaining higher bandwidth.
