METHOD AND DEVICE FOR TRANSMITTING TRAINING SYMBOL FOR ESTIMATING ANALOG BEAM IN WIRELESS ACCESS SYSTEM WHICH SUPPORTS HYBRID BEAMFORMING

Document Type and Number:

WIPO Patent Application WO/2016/028111

Kind Code:

A1

Abstract:

The present invention relates to a method and a device for transmitting a training symbol for hybrid beamforming. A method for transmitting a training symbol for estimating an analog beam in a wireless access system which supports hybrid beamforming according to one embodiment of the present invention comprises: a step of repeatedly transmitting a training symbol a number of times equivalent to the number of analog candidate beams; and a step of repeatedly transmitting a broadcasting channel a number of times equivalent to the number of analog candidate beams. A training symbol section, where the training symbol is transmitted, can be allocated to the same subframe as a subframe to which the repeatedly transmitted broadcasting channel is allocated.
