Abstract

The invention provides a downlink beam training indication method and device of an intelligent repeater, and relates to the technical field of communication. Comprises: a base station configures configuration information of a reference signal for beam management; the base station and the intelligent repeater transmit configuration information through Link1; the intelligent repeater performs reference signal processing after receiving the configuration information; the information of the processed reference signal is transmitted to the user equipment through the Link 2; the user equipment feeds back the information meeting the preset requirement to the base station, and determines a communication beam; and the base station indicates the intelligent repeater through the feedback information to determine a final communication beam with the user equipment. According to the invention, the traditional one-stage link from the BS to the UE is changed into two-stage link after amplification, so that the system performance can be effectively improved, and the capacity is increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a downlink beam training and indicating method and device for an intelligent repeater. Background technique [0002] Repeaters have existed in the 2G to 4G era, mainly including two types of repeaters, namely the amplification and forwarding type AF and the decoding amplification and forwarding DF type. [0003] Amplified and forwarded type AF: The repeater directly amplifies the received signal and sends it, which has the lowest delay and complexity. However, because it amplifies the useful signal while amplifying the noise and interference, it is new to the system. The ability to improve is limited [0004] Decoding, amplifying and forwarding type DF: The repeater first receives and decodes the signal, and then undergoes decoding and other processing, and sends it out through the radio frequency port. Because of the additional decoding / decoding process, this ty...
