    Abstract: The present application provides a channel state information (CSI) feedback and receiving method and device. The CSI feedback method by a UE comprises: determining, according to an indication of a base station, at least one CSI feedback configuration group configured by the base station, wherein each CSI feedback configuration group comprises at least one CSI feedback configuration; and upon determination of a need to report CSI, reporting, via a PUCCH or PUSCH, to the base station CSI acquired based on a first CSI feedback configuration, wherein the first CSI feedback configuration is a CSI feedback configuration determined, according to location information of a CSI feedback configuration in the most recent report or location information of a CSI feedback configuration indicated by the base station, from a corresponding CSI feedback configuration group by the UE. The present application supports independent reporting of location information and corresponding CSI, thus improving the detection performance of such information, and further supports a base station to acquire CSI corresponding to a specified CSI feedback configuration, thus enabling more flexible downlink scheduling and transmission.

    Abstract: The present disclosure relates to the field of wireless communication technology, and provides a data transmission method and a data transmission device, so as to solve the problem in the related art where, for 5G application scenarios, in the case that an uplink scheduling algorithm for a conventional 4G system continues to be used, a large number of control signaling overheads are required due to the meteoric growth in the number of UEs to be connected. In the present disclosure, a network side device determines non-orthogonal multiple access basic transmission units allocated to UEs, detects a pilot signal from each UE on the corresponding non-orthogonal multiple access basic transmission unit, and in the case that the pilot signal has been detected, performs data detection on the UE which has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.

    Abstract: An embodiment of the present invention relates to the technical field of wireless communications, in particular to an aerial calibration method, system and device. In the prior art, an air interface calibration method involving a user equipment (UE) requires the UE to feed back a channel coefficient, and a channel coefficient direct quantization method occupies a great deal of uplink overhead and reduces system efficiency. The present invention solves the above problem. The method in the embodiment of the present invention comprises: the UE measures a downlink channel and determines a downlink channel matrix; the UE determines a first weighting matrix for aerial calibration according to the downlink channel matrix; the UE notifies a network side of the determined first weighting matrix. In the embodiment of the present invention, a UE decomposes the characteristic value of the downlink channel matrix, or reports the identifier corresponding to the first weighting matrix to the network side device, thus reducing the occupied uplink overhead and improving system efficiency.

    Abstract translation: 本发明的实施例涉及无线通信的技术领域，特别涉及一种航空校准方法，系统和装置。 在现有技术中，涉及用户设备（UE）的空中接口校准方法要求UE反馈信道系数，并且信道系数直接量化方法占用大量的上行链路开销并降低系统效率。 本发明解决了上述问题。 本发明实施例中的方法包括：UE测量下行链路信道，确定下行链路信道矩阵; UE根据下行链路信道矩阵确定用于航空校准的第一加权矩阵; UE向网络侧通知所确定的第一加权矩阵。 在本发明的实施例中，UE将下行链路信道矩阵的特征值分解，或将与第一加权矩阵对应的标识符报告给网络侧设备，从而减少占用的上行链路开销并提高系统效率。

    Abstract: Provided in the embodiments of the present application are a channel state indication (CSI) information reporting and receiving method and a communication device, which are used to provide for a terminal in an NR system a solution for mapping CSI information to an uplink channel and transmitting the same. The method comprises: a terminal receives an uplink channel resource configuration signaling and/or a demodulation reference signal (DMRS) configuration signaling sent by a base station, and determines a mapping symbol set, wherein the DMRS configuration signaling is used to indicate the number of DMRSes configured by a system for an uplink channel and the time-frequency location of an occupied OFDM symbol, the uplink channel resource configuration signaling represents the time-frequency resource of the uplink channel, and the mapping symbol set is a set of symbols adjacent to the OFDM symbol; and the terminal measures a downlink channel, calculates CSI information, encodes the CSI information, and maps an information part comprising rank indication (RI) information onto an RE of at least one orthogonal frequency-division multiplexing (OFDM) symbol in the mapping symbol set to carry out transmission.
