Method for improving communication performance using vehicle provided with antennas

摘要

The present invention relates to a mobile communication system, and more specifically, to a method for providing an improved communication environment for a terminal using a vehicle provided with antennas, and to an apparatus for executing same. As related to one embodiment of the present invention, a data transceiving method for a terminal using a vehicle-mounted type communication module comprising a plurality of antennas comprises the steps of: establishing a wire data path with the communication module; negotiating multiple-antenna capabilities with a base station using multiple-antenna capabilities information of the communication module; and transmitting to the communication module multiple-antenna transmission parameters on the basis of the negotiation, and a data unit comprising uplink data to be transmitted to the base station, wherein the data unit, which has been generated in the medium access control (MAC) layer of the terminal and then converted into a radio frequency (RF) signal in the physical layer (PHY) of the communication module, can be transmitted to the base station using the plurality of antennas.

1. A data transceiving method for a terminal using a vehicle mounted-type communication module including a plurality of antennas, the method comprising:
establishing a wired data path with the vehicle mounted-type communication module; transmitting, to the vehicle mounted-type communication module, a subscriber identification module (SIM) information; receiving, from the vehicle mounted-type communication module, information indicating a completion of a negotiation with a base station using the SIM information and a multiple-antenna capabilities information of the vehicle mounted-type communication module; and transmitting, to the vehicle mounted-type communication module, a data unit comprising uplink data to be transmitted to the base station, wherein the data unit is generated in a medium access control (MAC) layer of the terminal, converted into a radio frequency (RF) signal in a physical (PHY) layer of the vehicle mounted-type communication module, and transmitted to the base station over the antennas, wherein the data unit is transmitted from the terminal to the vehicle mounted-type communication module via a service access point (SAP) between the MAC layer of the terminal and the PHY layer of the vehicle mounted-type communication module, and wherein the multiple-antenna capabilities information of the vehicle mounted-type communication module comprises at least two of the followings: the number of the antennas, a power amplifier class, or a buffer size.
