摘要： Provided are a method and device for acquiring pre-coding information, the method comprising: a network device uses N sub-codebooks to respectively pre-code a pilot frequency group containing K pilot frequencies to obtain N pre-coded pilot frequency groups, wherein the sub-codebooks are subsets of a pre-coding codebook, the pre-coding codebook comprises M pre-coding vectors, and each of the sub-codebooks comprises K pre-coding vectors; the network device sends a pre-coded pilot frequency group to a terminal device on each RB group among W RB groups; and the network device receives pre-coding information fed back by the terminal device with regard to any pre-coded pilot frequency group among W pre-coded pilot frequency groups. By means of the method and device for acquiring pre-coding information, a network device divides a pre-coding codebook into multiple sub-codebooks, the number of pre-coding vectors in each of the sub-codebooks is relatively small, and thus the number of pilot signals sent by the network device on various RB groups is reduced, and pilot frequency overheads on the various RB groups are reduced.

摘要： A signal processing method and a device are disclosed in the present invention, and relate to the technical field of communications. The device comprises a processor and a storage. The method comprises: setting each of the sampling point signals of an Orthogonal Frequency Division Multiplexing (OFDM) symbol and obtaining an input signal; calculating a constraint matrix according to the characteristic of a frequency selective fading channel; and calculating an output signal according to the sampling point signal, the input signal and the constraint matrix. The present invention solves a problem that the constraint matrix obtained according to the characteristic of a flat-fading channel is not applicable to the OFDM symbol due to that the OFDM symbol transmission is impacted by the frequency selective fading, and achieves an effect of reducing the impact on the OFDM symbol transmission caused by the frequency selective fading.

摘要： This application provides a technical solution for rank indication, and especially when a CQI number is not configured or a CQI number is 1, a network device configures a rank indication restriction parameter as that at least one of ranks whose index numbers are 0, 1, 2, and 3 is allowed to be reported by the terminal device; or even if the network device does not perform the foregoing configuration, and none of the ranks whose index numbers are 0, 1, 2, and 3 is allowed to be reported, the terminal device may select at least one rank for RI reporting, so as to resolve a problem that a system cannot work. On the other hand, according to embodiments of this application, bit overheads required for RI reporting may further be reduced.
