Abstract

The present invention provides a method for reporting and obtaining terminal information, a terminal and a base station, and relates to the technical field of mobile communication. The method for reporting terminal information includes: sending setting parameters of an antenna structure of a terminal to a base station; wherein the setting parameters include baseband parameters and / or radio frequency parameters; the baseband parameters include: the number of transceiver units supported by the terminal; the radio frequency parameters It includes one or more of the number of panels, frequency information supported by each panel, the number of beams supported by each panel, and the number of polarization directions of the antenna array on each panel. In the method for reporting terminal information provided by the present invention, the terminal sends the setting parameters of its own antenna structure to the base station, so that the network side understands the antenna array structure information on the terminal, and in subsequent use, the network side uses more antennas for user scheduling and data. During transmission, it provides the system with more efficient beam management, more accurate beam alignment, more optimized multi-user scheduling and multi-data stream transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method for reporting and obtaining terminal information, a terminal and a base station. Background technique [0002] Wireless access technology standards such as LTE (Long Term Evolution) / LTE-A (LTE-Advanced) are based on MIMO (Multiple-Input Multiple-Output, Multiple Input Multiple Output) + OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) built on the basis of) technology. Among them, the MIMO technology utilizes the spatial degrees of freedom that the multi-antenna system can obtain to improve the peak rate and system spectrum utilization. [0003] In the process of standardization development, the dimensions of MIMO technology continue to expand. In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. The MU-MIMO (Multi-User MIMO, multi-user multiple-input multiple-output) technology is enhan...
