Abstract
A method includes transmitting, at an LTE device configured to transmit data over an unlicensed band, first synchronization data over a first frequency channel of the unlicensed band during a timeframe. The method further includes transmitting, at one of the first LTE device or a second LTE device, second synchronization data over a second frequency channel of the unlicensed band during the same timeframe. The data transmissions of at least one of the first LTE device or the second LTE device are coordinated based on the synchronization data.
Claims20
A method comprising:
- transmitting, at a first LTE device configured to transmit data over an unlicensed band, first synchronization data over a first frequency channel of the unlicensed band during a timeframe;
- transmitting, at one of the first LTE device or a second LTE device configured to transmit data over the unlicensed band, second synchronization data over a second frequency channel of the unlicensed band during the same timeframe, wherein the timeframe comprises a plurality of fixed subframes of the unlicensed band, the plurality of fixed subframes having equal length;
- and
- coordinating one or more data transmissions of at least one of the first LTE device or the second LTE device based on the synchronization data.
A method comprising:
- transmitting, by a plurality of Long Term Evolution (LTE) devices configured to transmit data over an unlicensed band, a plurality of synchronization signals over a channel of the unlicensed band a plurality of times during a timeframe for transmission of synchronization signals, wherein the timeframe comprises a plurality of fixed subframes of the unlicensed band, the plurality of fixed subframes having equal length;
- and
- coordinating one or more data transmissions of a first LTE device and a second LTE device of the plurality of LTE devices based on the synchronization signals.
An LTE device configured to transmit data over an unlicensed band, comprising:
- circuitry configured to:
- transmit first synchronization data over a first frequency channel of the unlicensed band during a timeframe;
- receive second synchronization data over a second frequency channel of the unlicensed band during the same timeframe, wherein the timeframe comprises a plurality of fixed subframes of the unlicensed band, the plurality of fixed subframes having equal length;
- and
- coordinate one or more data transmissions over the unlicensed band based on the synchronization data.
