Patent ID: 8843145

Claim:
A method of transmitting data in a multiple-carrier system, the multiple-carrier system including a carrier including a first guard band, a data band, and a second guard band in ascending order of frequency, the method comprising: mapping guard physical resource units (PRUs) in the first guard band and the second guard band to guard miniband logical resource units (NLRUs) in a frequency partition, the guard PRUs being indexed in such a manner that a first guard PRU in the first guard band and a second guard PRU in the second guard band are indexed in turn; and transmitting data through the guard NLRUs to a user equipment, wherein the guard PRUs are indexed by the equation as follows: GPRU[ i ]=PRU1[ i/ 2], for even i GPRU[ i ]=PRU2[( i− 1)/2], for odd i, where GRPU[i] is a re-arranged guard PRU, “i” is an index number, PRU 1 is the first guard PRU in the first guard band, and PRU 2 is the second guard PRU in the second guard band.
