Abstract
Provided is a method for estimating a timing advance (TA) for each beam in a wireless communication system. First, a terminal transmits K preambles, to which K mutually different beam formings are applied, to a base station. The base station estimates the TA for each of the K received preambles. The base station can determine the final TA value of the terminal on the basis of the TAs estimated for each of the K preambles.
Claims15
A method for estimating, by a base station (BS), a timing advance (TA) for each beam in a wireless communication system, the method comprising:
- receiving K preambles, to which K different beamformings are applied, from a user equipment (UE);
- and
- estimating a TA for each of the K preambles.
A method for applying, by a user equipment (UE), a timing advance (TA) in a wireless communication system, the method comprising:
- transmitting K preambles, to which K different beamformings are applied, to a base station (BS);
- and
- receiving a TA command comprising a final TA value, which is determined by the BS based on the K preambles, from the BS.
