Abstract:
A method of positioning a terminal includes: receiving a first radio signal generated through beamforming from a base station; obtaining a cell ID and a beam ID from the first radio signal; obtaining a received signal intensity of the first radio signal; and estimating a first position of the terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with the cell ID, the beam ID, and the received signal intensity obtained from the first radio signal.
Abstract:
A method for adjusting a hybrid automatic repeat request (HARQ) timing is provided. A base station adjusts a HARQ timing of a mobile station according to a system environment, and transmits radio resource allocation information including the adjusted HARQ timing information to the mobile station. The mobile station adjusts HARQ timing according to HARQ timing information, and transmits a HARQ signal according to the adjusted HARQ timing.
Abstract:
Provided is a network access management method of a terminal, the method including determining whether a terminal located adjacent to a railway dedicated wireless communication network is a common terminal or a railway dedicated terminal, based on a unique identifier (ID) of the terminal, and handing over the terminal to a different communication network allowing an access based on a result of the determining.
