Abstract: This application provides a method for obtaining downlink channel information. The method includes: performing preceding weighting on M CSI-RSs of each of N sub-cycles, where each sub-cycle is a quantity of measurement pilot subframes for bearing and transmitting the M CSI-RSs; sending the M weighted CSI-RSs to UE; receiving M PMIs and M CQIs that are sent by the UE and that correspond to the M CSI-RSs, where the M PMIs and the M CQIs are obtained by the UE by separately measuring the M weighted CSI-RSs based on a set a rank 1 preceding codebooks corresponding to the predetermined antenna quantity; obtaining M signal-to-noise ratios of a downlink channel of the UE according to the M CQIs, obtaining M equivalent codebooks according to the M PMIs and weights of the preceding weighting; and obtaining a covariance matrix according to the M signal-to-noise ratios and the M equivalent codebooks.

Abstract: Embodiments of the present disclosure relate to the field of communications technologies, and disclose a data stream transmission method, and a related device and system. The data stream transmission method includes: a user equipment establishes a first network link over a first network and a second network link over a second network with a network side, where the first network is different from the second network; the user equipment associates the first network link with the second network link; and the user equipment distributes, according a scheduling algorithm, a data stream to the first network link and to the second network link for transmission. In the embodiments of the present disclosure, hybrid transmission of a data stream may be implemented in different networks. Compared with an existing solution, in the embodiments of the present disclosure, distribution may be performed more flexibly, and a quality of service assurance may be improved.
