Abstract
Methods and apparatuses for indicating a frequency offset of a non-anchor carrier are disclosed. A method comprising: transmitting a broadcast signal on an anchor carrier and transmitting system information on a non-anchor carrier, wherein the broadcast signal includes a frequency offset of the non-anchor carrier to the anchor carrier.
Claims20
A method performed by a base station, the method comprising:
- transmitting a broadcast signal on an anchor carrier, wherein the anchor carrier is within a guard band associated with a Long-Term Evolution (LTE) carrier, and the broadcast signal includes bandwidth information of the LTE carrier that includes an LTE carrier bandwidth selected from the group comprising 5 MHz, 10 MHz, 15 MHz, and 20 MHz;
- and
- 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.

A base station, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the base station to:
- transmit a broadcast signal on an anchor carrier, wherein the anchor carrier is within a guard band associated with a Long-Term Evolution (LTE) carrier, and the broadcast signal includes bandwidth information of the LTE carrier that includes an LTE carrier bandwidth selected from the group comprising 5 MHz, 10 MHz, 15 MHz, and 20 MHz;
- and
- transmit 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.
