transmitting a system information on a non-anchor carrier, wherein the non-anchor carrier is within the guard band associated with the LTE carrier, and the broadcast signal indicates:
a frequency offset between the anchor carrier and the LTE carrier; and
a frequency offset between the non-anchor carrier and the anchor carrier, wherein the frequency offset between the non-anchor carrier and the anchor carrier indicates the non-anchor carrier is located on the same side of the guard band associated with the LTE carrier with the anchor carrier or the non-anchor carrier is located on the opposite side of the guard band associated with the LTE carrier to the anchor carrier.

9. The base station of claim 6 , wherein the frequency offset of the non-anchor carrier to the anchor carrier depends on the bandwidth information of the LTE carrier.
10. The base station of claim 6 , wherein the non-anchor carrier is adjacent to the anchor carrier.
11. A method performed by a user equipment (UE), the method comprising:
receiving a broadcast signal on an anchor carrier; and
receiving a system information on a non-anchor carrier, wherein the anchor carrier is within a guard band associated with a Long-Term Evolution (LTE) carrier that includes an LTE carrier bandwidth selected from the group comprising 5 MHz, 10 MHz, 15 MHz, and 20 MHz, and the broadcast signal includes bandwidth information of the LTE carrier, the non-anchor carrier is within the guard band associated with the LTE carrier, and the broadcast signal indicates:
a frequency offset between the anchor carrier and the LTE carrier; and
a frequency offset between the non-anchor carrier and the anchor carrier, wherein the frequency offset between the non-anchor carrier and the anchor carrier indicates the non-anchor carrier is located on the same side of the guard band associated with the LTE carrier with the anchor carrier or the non-anchor carrier is located on the opposite side of the guard band associated with the LTE carrier to the anchor carrier.
12. The method of claim 11 , wherein the frequency offset of the non-anchor carrier to the anchor carrier includes an information of the non-anchor carrier having a higher or lower frequency than the anchor carrier and an absolute frequency offset value of the non-anchor carrier to the anchor carrier or some combination thereof.
13. The method of claim 11 , wherein the frequency offset of the non-anchor carrier to the anchor carrier includes a relative frequency offset of the non-anchor carrier to the anchor carrier.
14. The method of claim 11 , wherein the frequency offset of the non-anchor carrier to the anchor carrier depends on the bandwidth information of the LTE carrier.
15. The method of claim 11 , wherein the non-anchor carrier is adjacent to the anchor carrier.
