Problems solved by technology

However, there is a disadvantage that since this technique is based on a system using an omnidirectional antenna, it is difficult to apply to a beamforming system that causes different path losses depending on transmit / receive beam directions

Abstract

An UpLink (UL) control method and apparatus for in a wireless communication system supporting beamforming are provided. A method of a Mobile Station (MS) for UL control in the wireless communication system supporting the beamforming includes receiving a plurality of DownLink (DL) reference signals from a plurality of Base Station (BS) transmission beams using a plurality of MS reception beams having different directivity, measuring a path loss based on a reception signal strength of each of the plurality of DL reference signals received through different transmission / reception beams, selecting an MS transmission beam for uplink based on the path loss value measured for each of the plurality of DL reference signals, and transmitting a UL signal to a BS using the selected MS transmission beam.

Description

technical field [0001] The present invention relates to an uplink (UL) control method and device in a wireless communication system. More particularly, the present invention relates to a UL control method for access of a mobile station (MS) to a base station (BS) in a wireless communication system. Background technique [0002] The average amount of data used by a mobile communication subscriber has increased geometrically, and user demands for higher data transmission rates have increased at a similar rate. In order to address this increasing demand for a high data transmission rate, research is being conducted for introducing an ultra-high frequency band communication technology of 30G Hertz (GHz) or higher, that is, a millimeter wave system. [0003] In mmWave systems, severe propagation path loss occurs, and the coverage of BS is significantly reduced. In order to solve this problem in the millimeter wave system, it is expected to introduce a beamforming technique that...
