Abstract

A beam allocation method of a Base Station (BS) in a wireless communication system is provided. The method includes transmitting a reference signal to a Mobile Station (MS) using a plurality of downlink transmit (Tx) beams, receiving information of a plurality of candidate downlink Tx beams determined by the MS in response to the received reference signal, selecting at least one downlink Tx beam from the plurality of candidate downlink Tx beams according to a predefined rule, generating control information for burst transmission, comprising the selected at least one downlink Tx beam information, transmitting the control information to the MS using the selected at least one downlink Tx beam, and transmitting a data burst based on Tx beam information included in the control information.

Description

technical field [0001] The present invention relates to wireless communication systems. More particularly, the present invention relates to methods and apparatus for beam allocation in wireless communication systems. Background technique [0002] Wireless communication systems are advancing to support high data rates and keep up with the ever-increasing demand for wireless data traffic. [0003] So far, the 4th generation (4G) system mainly aims to improve the spectral efficiency in order to increase the data transfer rate. However, it is difficult to meet the ever-increasing demand for wireless data traffic with only spectral efficiency enhancement. [0004] To solve this problem, one method utilizes a wide frequency band. Since it is difficult to secure a wide frequency band in the current frequency (ie, below 10 GHz), a wider frequency band is required. [0005] However, as the transmission frequency used for wireless communication rises, the propagation distance is r...
