A method for indicating channel state information CSI measurement and a communication apparatus. A network device indicates, to a terminal device by using first indication information, one or more frequency domain units in a downlink reference signal resource that are used by the terminal device to obtain CSI. The terminal device determines, based on the first indication information, which frequency domain units in the downlink reference signal resource are used to obtain the CSI, and perform measurement in the frequency domain unit to obtain the CSI. The network device flexibly configures CSI measurement based on a system status, to control obtaining of the CSI. This helps the terminal device obtain the CSI more pertinently based on the indication in different cases.

Method for indicating channel state information CSI measurement and communication apparatus

This application relates to the field of communication technologies, and provides an information transmission method and an apparatus. In this method, a radio access network device sends, to a terminal device, first indication information indicating first information and second information and second indication information indicating a first quantity of DFT vectors, the first information indicates a first quantity of to-be-selected ports, and the second information indicates a first compression factor. The radio access network device further sends a reference signal to the terminal device. The terminal device sends downlink channel state information to the radio access network device based on the first indication information, the second indication information, and the reference signal. The compression factor is a compression factor of a complex coefficient matrix. There is a correspondence between the compression factor and a quantity of transport layers.

Information transmission method and apparatus

This application provides a stiffener ring and a surface packaging assembly. The stiffener ring is configured to correct warpage of a substrate of the surface packaging assembly. The stiffener ring includes an annular stiffener ring body and an adjustment block that is disposed at a same layer as the stiffener ring body and that is fastened to at least one corner of the stiffener ring body. A coefficient of thermal expansion of the adjustment block is less than a coefficient of thermal expansion of the stiffener ring body. Coordination between the adjustment block and the stiffener ring body alleviates an 'M-shape' overpressure phenomenon of a warpage deformation caused by the stiffener ring to the substrate at a high temperature, reduces warpage of the substrate, and improves flatness of the surface packaging assembly.

Channel information feedback method and communication apparatus

Example channel measurement methods and communications apparatus are described. One example method includes receiving a precoded reference signal by a terminal device, where the precoded reference signal is obtained by precoding a reference signal based on K angle vectors and L delay vectors. First indication information is generated and sent, where the first indication information indicates P weighting coefficients corresponding to P angle-delay pairs. The P weighting coefficients are determined by using the precoded reference signal. The P angle-delay pairs and the P weighting coefficients corresponding to the P angle-delay pairs are used to determine a precoding matrix. Each angle-delay pair includes one of the K angle vectors and one of the L delay vectors. The K angle vectors and the L delay vectors are determined based on uplink channel measurement.
