Method for wireless communication based on relay and apparatus for the same
First Claim
1. A method for transmitting signals performed in a first terminal connected to a first base station in a communication system, the method comprising:
- wherein downlink transmission between the first terminal and the first base station is performed through a first radio link, uplink transmission between the first terminal and the first base station is performed through a second radio link, the first base station is connected to a second base station which is connected to a second terminal, downlink transmission between the second terminal and the second base station is performed through the second radio link, and uplink transmission between the second terminal and the second base station is performed through the first radio link,receiving scheduling information from the first base station through the first radio link;
generating uplink data based on the scheduling information;
performing puncturing on uplink data symbols positioned in a region to which a downlink synchronization signal is allocated, wherein the downlink synchronization signal is transmitted from the second base station to the second terminal through the second radio link; and
transmitting punctured uplink data through the second radio link.

Abstract
Methods for wireless communications based on relay and apparatuses for the same are disclosed. The method for a terminal to transmit signals comprises receiving scheduling information from a base station connected to the terminal; generating uplink data based on the scheduling information; performing punctuation on a data symbol positioned in a region through a downlink synchronization signal is transmitted in the generated uplink data; and transmitting the punctured uplink data. Therefore, the terminal may acquire synchronization signal easily, and perform neighbor cell search correctly based on the acquired synchronization signal.
