    Abstract: In the field of communication technologies, a method and an apparatus for acquiring a Precoding Matrix Indicator (PMI) and a Precoding Matrix (PM) are provided. The method includes: acquiring a reference PMI and a differential PMI according to a first non-differential codebook and a first diagonal differential codebook, where codewords included in the first diagonal differential codebook form a diagonal matrix. The apparatus includes a PMI acquiring module. Acquiring a reference PMI and a differential PMI according to a non-differential codebook and a diagonal differential codebook can reduce the feedback overhead or improve the feedback precision; and the fact that codewords included in the diagonal differential codebook form a diagonal matrix can maintain amplitude characteristics (for example, a constant modulus characteristic, and a finite character set constraint characteristic) of elements of the non-differential codebook or facilitate power distribution among antennas.

    Abstract: The present disclosure relates to methods for feeding back channel state information, user equipment, and base stations. One example method includes receiving a reference signal sent by a base station, selecting a precoding matrix W from a codebook according to the reference signal, where a column vector of the precoding matrix W may be expressed as α[vejϕv]T, v=[1 ejθ], and sending a precoding matrix indicator (PMI) to the base station, where the PMI corresponds to the precoding matrix W.

    Abstract: A signal sending method, a signal receiving method, and a device are provided. A part that is of a first signal and that is carried on the kth subcarrier in the ith subcarrier group in N subcarrier groups is xi,nid(k), and a sequence {si,nid(k)} related to xi,nid(k) is one of enumerated sequences. The enumerated sequences are sequences with relatively good cross-correlation. Therefore, for two subcarrier groups, provided that selected {si,nid(k)} is two of the enumerated sequences, cross-correlation between signals carried in the two subcarrier groups can be ensured to be relatively good, thereby reducing interference between the signals and improving channel estimation performance.

    Abstract: A network device sends a first physical channel to user equipment on resources of one or more candidate physical channels. Correspondingly, the user equipment monitors one or more candidate physical channels in a candidate physical channel set, to receive the first physical channel on the resources of the one or more candidate physical channels. A payload of the first physical channel includes control information and a transport block, the control information includes first information, the first information is used to indicate an acknowledgment resource to the user equipment, and the acknowledgment resource is a resource used by the user equipment to send acknowledgment information to the network device. After receiving the first physical channel, the user equipment sends the acknowledgment information to the network device on the acknowledgment resource; and correspondingly, the network device receives the acknowledgment information on the acknowledgment resource.

    Abstract: A channel information reporting method and apparatus and a system are used to improve adaptive performance of a link. A first device includes: a receiving module, configured to receive a reference signal from a second device; a processing module, configured to: perform channel estimation based on the reference signal to obtain a channel matrix, decompose the channel matrix to obtain an unquantized precoding matrix, and generate channel information used to describe the unquantized precoding matrix; and a sending module, configured to send the channel information used to describe the unquantized precoding matrix to the second device. The second device sends the channel information used to describe the unquantized precoding matrix. Therefore, a quantization error is avoided, so that a precoding matrix obtained by the first device is more accurate, thereby effectively improving the adaptive performance of the link.

    Abstract: The present disclosure relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI trigger signaling, so that a base station transmits a CSI-RS only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced.
