Abstract

The invention provides a method, device, computer-readable storage medium and electronic equipment for determining the reciprocity of equipment beams, relates to the technical field of communication, and is used for improving communication quality. The method for determining the beam reciprocity of a device in the present invention includes: instructing the second device to use the transmission beam obtained based on the beam reciprocity to send a reference signal; receiving the reference signal sent by the second device, and calculating the received reference signal Quality: receiving multiple beam training signals sent by the second device, and calculating the receiving quality of the multiple beam training signals respectively; combining the receiving quality of the reference signal and the receiving quality of the multiple beam training signals The obtained reference reception quality is compared, and it is determined whether the beam reciprocity of the second device is established according to the comparison result. The present invention can accurately determine whether the beam reciprocity of the second device is established, thereby accurately selecting the corresponding beam to transmit data, thereby improving the communication quality.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and electronic equipment for determining equipment beam reciprocity. Background technique [0002] In view of the important role of MIMO (Multiple-Input Multiple-Output) technology in improving the peak rate and system spectrum utilization, LTE (Long Term Evolution, Long Term Evolution) / LTE-A (LTE-Advanced) and other wireless access All input technical standards are built on the basis of MIMO+OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology. The performance gain of MIMO technology comes from the spatial freedom obtained by multi-antenna systems. Therefore, one of the most important evolution directions of MIMO technology in the standardization development process is the expansion of dimensions. [0003] In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. Rel-9 focuses on enha...
