Abstract:
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. Disclosed is a method and apparatus for transmitting or receiving a reference signal in a beamforming communication system. The method comprises the steps of: generating a reference signal sequence for a reference signal that can be used for beam searching; mapping the reference signal sequence to modulation symbols corresponding to resource elements having a predetermined identical subcarrier spacing among resource elements that can be used to transmit the reference signal; generating an OFDM symbol signal including the modulation symbols; and transmitting the OFDM symbol signal using at least one predetermined transmission beam among transmission beams that can be used by a base station.

Claim (Index 7):
The method of  claim 1 , wherein the reference signal sequence is defined as the following equation, r l , n s \ue8a0 ( m ) = 1 2 \ue89e ( 1 - 2 \u00b7 c \ue8a0 ( 2 \ue89e \ue89e m ) ) + j \ue89e 1 2 \ue89e ( 1 - 2 \u00b7 c \ue8a0 ( 2 \ue89e \ue89e m + 1 ) ) , \n \ue89e m = 0 , 1 , \u2026N RB DL - 1 c init = 2 10 \u00b7 ( 7 \u00b7 ( n s + 1 ) + l + 1 ) \u00b7 ( 2 \u00b7 N ID cell + 1 ) + 2 \u00b7 N ID cell + 1 where the reference signal sequence is mapped to a modulation symbol according to the following equation, { a k , l ( p ) = 0 , if \ue89e \ue89e k \ue89e \ue89e mod \ue89e \ue89e 4 \u2260 0 a k , l ( p ) = r l , n s \ue8a0 ( m ) , if \ue89e \ue89e k \ue89e \ue89e mod \ue89e \ue89e 4 = 0 \ue89e \n \ue89e m = 0 , 1 , \u2026 \ue89e , N RB DL \u00b7 N sc RB / 4 - 1 where, k and l denote indexes on a frequency domain and indexes on a time domain, respectively, p and ns denote an antenna port number and a slot number, respectively, N ID cell  and N RB DL  denote a cell identifier (ID) and a number of downlink resource blocks (RBs), r l,n s (m) is an mth reference signal sequence, and a k,l (p)  denotes a modulation symbol which is carried through a kth subcarrier.
