- This application relates to the field of communications, and in particular to a method for determining channel information, network equipment, and terminal equipment.
- the operating frequency band supported by the system is increased to above 6 GHz.
- the high frequency band has relatively abundant idle frequency resources, which can provide greater throughput for data transmission.
- the wavelength of the high-frequency signal is short, and more antenna elements can be arranged on the panel of the same size, and beamforming technology can be used to form a beam with stronger directivity and narrower lobes.
- the analog beamforming is a full-bandwidth transmission, and each polarization direction array element on the panel of each high-frequency antenna array can only transmit the analog beam in a time-division multiplexing manner.
- the shaping weight of the analog beam is realized by adjusting the parameters of the RF front-end phase shifter and other equipment.
- polling is usually used for the training of analog beamforming vectors, that is, the array element of each polarization direction of each antenna panel sends the training signal in turn at the appointed time in a time-division multiplexing manner. (That is, the candidate shaping vector), the terminal feeds back the beam report after measurement, for the network side to use the training signal to implement analog beam transmission during the next service transmission.
- the content of the beam report usually includes several optimal transmit beam identifiers and the measured received power of each transmit beam.

- the CSI-RS type is aperiodic CSI-RS
