Classification: CPC H | IPC H

Claim 18:
19. A communication device, comprising: a processor, a memory and a transceiver; wherein the processor is configured to read computer instructions in the memory to perform:
determining an orthogonal beam group and precoding matrix information according to codebook parameter information; wherein a same beam in the orthogonal beam group has same specified coefficients in first and second polarization directions, each of the specified coefficients comprises an amplitude coefficient and/or a phase coefficient, the precoding matrix information comprises the specified coefficients and adjustment factors, the adjustment factors are used together with the specified coefficients to determine linear combination coefficients except the specified coefficients in a linear combination coefficient set; wherein the specified coefficients are a part of coefficients in the linear combination coefficient set;
sending the precoding matrix information to a network-side device.
