Abstract
In a wireless network, a primary synchronization signal and a secondary synchronization signal are sent at a predetermined bandwidth in a transmission. The predetermined bandwidth is a lowest operating bandwidth of the wireless network. Data is also sent in the transmission using an operating bandwidth greater than the lowest operating bandwidth.
Claims23
A method performed by a base station, the method comprising:
- transmitting, by the base station, a first signal having a first cell bandwidth in a time slot, wherein the first signal includes a synchronization signal having a second bandwidth, wherein the second bandwidth is based on a lowest potential cell bandwidth, the synchronization signal has a duration less than the first signal, and wherein the first signal includes physical data signals in the first cell bandwidth outside of the second bandwidth of the synchronization signal.
A base station comprising:
- an antenna;
- and
- a transmitter, operatively coupled to the antenna, configured to transmit a first signal having a first cell bandwidth in a time slot, wherein the first signal includes a synchronization signal having a second bandwidth, wherein the second bandwidth is based on a lowest potential cell bandwidth, wherein the synchronization signal has a duration less than the first signal, and wherein the first signal includes physical data signals in the first cell bandwidth outside of the second bandwidth of the synchronization signal.
A user equipment (UE) comprising:
- an antenna;
- and
- a receiver, operatively coupled to the antenna, configured to receive a synchronization signal, wherein the synchronization signal has a second bandwidth, wherein the second bandwidth is based on a lowest potential cell bandwidth, wherein the synchronization signal is received in a time slot, wherein the time slot has a first signal, transmitted by a base station, including the synchronization signal, wherein the first signal has a first cell bandwidth and includes physical data signals in the first cell bandwidth outside of the second bandwidth of the synchronization signal, and the synchronization signal has a duration less than the first signal.
