Method of transmitting and receiving data in a wireless system

#The present invention relates to a wireless communication system, and more particularly, to a method of transmitting data in a wireless communication system.

#The present invention relates to a method of overcoming a delay of signal in an environment in which the signal delay takes place.

#As a representative example of generating a signal delay, there is a coordinated multi-point (hereinafter abbreviated CoMP). Specifically, when a receiving stage receives signals from multiple points located physically existing at different locations, the signals received from the multiple points may not be synchronized with each other. For instance, when a base station existing at one location simultaneously transmits signal into multi-cell identified at the corresponding point, timing ambiguity or delay tends not to occur. On the contrary, in case that signals are transmitted/received to/from physically different locations, different delays are experienced while the signals propagate to the physically different locations. Hence, the signals received by the corresponding receiving stage have delay values differing from each other. Moreover, in a downtown area, it is easy to observe that signals arrive at a receiving stage with different delays despite a physically equal distance due to waveguide effect of signal and the like. Due to this reason, it is difficult to implement CoMP (coordinated multi-point) schemes.

#The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

#In the drawings:

#FIG. 1 is a diagram for a structure of a transmit unit in a data transmitting method according to a first embodiment of the present invention;

#Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In the following detailed description of the invention includes details to help the full understanding of the present invention. Yet, it is apparent to those skilled in the art that the present invention can be implemented without these details. For instance, although the following descriptions are made in detail on the assumption that a mobile communication system includes 3GPP LTE system, they are applicable to other random mobile communication systems except unique features of 3GPP LTE.

#Occasionally, to prevent the present invention from getting vaguer, structures and/or devices known to the public are skipped or can be represented as block diagrams centering on the core functions of the structures and/or devices. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

#Besides, in the following description, assume that a terminal is a common name of such a mobile or stationary user stage device as a user equipment (UE), a mobile station (MS) and the like and that a base station is a common name of such a random node of a network stage communicating with a terminal as a node B, eNode B, a base station and the like.
