    Abstract: Embodiments of the present invention provide a multi-user interference suppression method, terminal and base station. The method includes performing layer mapping on and precoding service data of each of paired users to obtain precoded output data, mapping the precoded output data and a common pilot sequence to a port of an antenna array for sending to each user by using the antenna array. Correspondingly, the embodiments of the present invention further provide a data receiving method, base station and terminal. By using a common pilot sequence based on the paired users, the same pilot sequence is used for each user in the paired users of a cell or a collaborative area, which is different from the technical solution in the prior art where a user-specific pilot is used and pilots of different users are orthogonal.

    Abstract: This application discloses a method and an apparatus for transmitting a pilot signal, so that more flexible resource configuration can be achieved, thereby improving resource usage. The method includes: determining, by a transmit end device based on prestored N pilot patterns, a target time-frequency resource for transmitting a pilot signal, where the target time-frequency resource corresponds to a total quantity of layers of a to-be-transmitted data stream, the N pilot patterns are different from each other, and N is a natural number greater than or equal to 1; and sending, by the transmit end device, indication information to a receive end device, where the indication information is used to instruct the receive end device to transmit the pilot signal to the transmit end device based on the target time-frequency resource.

    Abstract: Embodiments of the present invention disclose a precoding information collection method and a transmission device and relate to the communications field. A specific solution is: precoding, by a transmit side, a first pilot signal according to a first precoding matrix, and sending a precoded first pilot signal to a receive side, where the first precoding matrix is the same as a precoding matrix used for current data transmission; precoding, by the transmit side, N second pilot signals according to N second precoding matrices, and sending N precoded second pilot signals to the receive side, where N is an integer greater than or equal to 1, the second precoding matrices used for precoding the second pilot signals are different from each other, and the N second precoding matrices are different from the first precoding matrix; and receiving, by the transmit side, precoding feedback information sent by the receive side.

    Abstract: Embodiments of the present invention provide a channel state information obtaining method and a device, where the method includes: determining, by a base station according to radio resource usage, a special timeslot in a frequency range used for downlink data transmission; sending special-timeslot configuration information to user equipment, where the special-timeslot configuration information is used to configure the user equipment to send the uplink physical signal over a downlink frequency band in the special timeslot; and performing channel estimation according to the uplink physical signal after receiving the uplink physical signal sent by the user equipment, to obtain channel state information. Compared with a technical solution in the prior art in which user equipment obtains channel state information and then feeds back the channel state information to a base station, system overheads caused in obtaining, by the base station, the channel state information are reduced.
