Abstract

The embodiment of the present invention discloses a method for determining channel information, network equipment and terminal equipment, so as to solve the signaling overhead and time required to update, activate or indicate channel information using MAC CE commands in multi-CC, multi-BWP or multi-TRP scenarios. The method includes: using the medium access control MAC control element CE command to update, activate or indicate the parameter information of the first channel or the first reference signal RS; the parameter information of the first channel or the first reference signal RS is used to determine the Parameter information of the second channel or the second RS under preset conditions; wherein, the parameter information includes at least one item of transmission configuration indication TCI status information, spatial relationship information, and path loss PL RS. The technical solution improves the method for determining the parameter information of the second channel or the second RS under multiple different conditions (scenarios), and reduces signaling overhead and time delay when configuring or indicating channel information.

Description

Technical field [0001] The present invention relates to the field of communications, and more particularly to a method of determining a channel information, a network device, and a terminal device. Background technique [0002] During the third-generation partner program (3GPP), the operating frequency band supported by the system is upgraded to 6GHz. High-frequency sections have a relatively rich frequency of idle frequency resources, which can provide greater throughput for data transmission. The wavelength of the high frequency signal is short to the same low frequency band, which can arrange a more antenna element on the same size panel, and beamhed to be stronger and the beam of the wavefoot is formed by the beam excipient technology. [0003] The analog beamforming is a full bandwidth transmitted, and each polarization direction of the panel of each high-frequency antenna array can only transmit analog beam in a manner in which time multiplexes. The mountable weight of the ...
