    Abstract: This application relates to the field of communications technologies, and discloses a transport block generation method and apparatus. The method includes: determining a TBS based on an MCS of a receiving device, a resource characteristic of an RB allocated to the receiving device, and a quantity of symbols, where the quantity of symbols is a quantity of symbols included in each RB, and each RB includes a same quantity of symbols; and generating a TB based on a TBS. TBS is determined based on the MCS of the receiving device, a quantity of RBs allocated to the receiving device, and the quantity of symbols included in the RB, and the TB is generated based on the determined TBS. The quantity of symbols included in the RB is considered in determining the TBS. Therefore, the determined TBS may vary with the quantity of symbols included in the RB.

    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: Example precoding vector indication methods, precoding vector determining methods, and communications apparatus to reduce feedback overheads are described. One example method includes generating and sending a channel state information (CSI) report by a terminal device. A network device determines a precoding vector of one or more frequency domain units based on the CSI report. The CSI report is used to indicate M space-frequency units and a weighting coefficient of a part or all of the M space-frequency units, each of the M space-frequency units corresponds to one beam vector and one frequency domain vector, and a weighted sum of the part or all of the M space-frequency units is used to determine the precoding vector of the one or more frequency domain units.

    Abstract: Aspects of the present application relate to sensing-based, mobility-aware waveform adaptation. A transmitting device may estimate a velocity vector for a mobile device. The velocity vector estimate may be based on measurements made at the mobile device and fed back to the transmitting device or based on measurements made at other devices in the environment and provided to the transmitting device. The transmitting device may, based on the estimate of the velocity vector, obtain a Doppler variable estimate for a signal path between the transmitting device and the mobile device. The transmitting device may then adapt a to-be-transmitted waveform based on the Doppler variable estimate for the signal path and then transmit the adapted waveform. Occasionally, the transmitting device may obtain updates to parameters that describe the location and mobility of the mobile device. On the basis of the updates, the transmitting device may update the waveform adaptation.

    Abstract: A channel state information feedback method includes: a terminal receives first indication information from a network device, and the terminal sends channel state information to the network device. The first indication information is used to indicate a type of a right multiplication matrix in a first codebook, and the first codebook satisfies a formula (I). W is the first codebook, W1 is a port selection matrix, (II) is a linear superposition coefficient matrix, Wf is the right multiplication matrix, and (III) is a conjugate transpose of Wf, and is used by the terminal to determine the channel state information based on the first codebook. According to the method, when there are a plurality of codebooks, the codebook used by the terminal to obtain the CSI can be clearly indicated.
