METHOD AND APPARATUS FOR TRANSMITTING DATA

摘要

The present invention relates to a method and apparatus for transmitting data. In the method for transmitting data, a first transmission point can determine a reference signal sequence r(m) and transmit the determined reference signal sequence r(m) to a terminal. A parameter ns from among parameters for generating an initial value c_init of a pseudorandom sequence in order to determine the reference signal sequence can be determined on the basis of the slot number of a wireless frame, which a second transmission point transmits to the terminal. Accordingly, the demodulation performance of the terminal can be enhanced.

1. A method of transmitting data, the method comprising:
transmitting a reference signal sequence r(m) to a terminal, wherein a first transmission point determines the reference signal sequence r(m) as follows:r(m)=12(1-2·c(2m))+j12(1-2·c(2m+1)), wherein m an RB (resource block) corresponding to a frequency bandwidth of a downlink channel, and c( ) denotes a pseudo-random sequence, wherein an initial value, cinit, of the pseudo-random sequence is determined as follows:
cinit=(└ns/2┘+1)·(2X+1)·216+Y, wherein ns is a slot number in a radio frame, X is a first initial value determining parameter, and Y is a second initial value determining parameter, and wherein ns is determined based on a slot number of a radio frame transmitted from a second transmission point to the terminal.
