Abstract

The invention discloses a pilot frequency measurement method. The method comprises: the receiving end determines the port configuration of the pilot frequency measurement; the receiving end adopts the port configuration, receives the pilot frequency signal, and obtains channel information through estimation. Correspondingly, the present invention also discloses a receiving end for pilot frequency measurement. Even if the number of antenna ports increases sharply, a part of the ports can still be selected as ports for sending pilot signals as required, without limiting the number of ports for sending pilot signals. The number of ports solves the problem of pilot configuration when the number of antenna ports surges.

Description

technical field

[0001] The invention relates to a three-dimensional (3D) beam forming technology, in particular to a pilot frequency measurement method and device. Background technique

[0002] 3D beamforming technology is an important technology for improving cell resource utilization and solving inter-cell interference. The basic starting point of 3D beamforming is to use both horizontal and vertical beams to achieve higher space Reusability, and improve system throughput.

[0003] In order to realize 3D beamforming, multiple groups of antennas are usually required to be used together, which involves the problem of pilot design under complex antenna configurations. At present, in the channel measurement in R10, different specific antenna port numbers adopt different pilot configurations, and support four pilot configurations of 1-port transmission, 2-port transmission, 4-port transmission, and 8-port transmission, and there are corresponding Pilot transmission pattern. ...
