Patent ID: 8743785

Claim:
A method for communications controller operations in a multi-carrier system, the method comprising: generating broadcast information for a broadcast channel; generating synchronization information for a synchronization channel; selecting, by a lower power cell, a first center frequency location for a first physical broadcast channel (PBCH) of the low power cell that is different than a second center frequency location of the synchronization channel transmitted by the low power cell and a second PBCH transmitted by a high power cell, wherein the low power cell and the high power cell are located in a heterogeneous network (Het-Net); mapping, by the lower power cell, the broadcast information onto subcarriers in a first group of contiguous subcarriers centered at the first center frequency location; mapping, by the lower power cell, the synchronization information onto subcarriers in a second group of contiguous subcarriers centered at the second center frequency location; and transmitting, by the lower power cell, the first PBCH over the first group of contiguous subcarriers centered at the first center frequency location; and transmitting, by the lower power cell, the synchronization channel over the second group of contiguous subcarriers centered at the second center frequency location.
