Abstract
A method includes transmitting, at an access point configured to transmit data over an unlicensed band, a single message prior to transmitting data over a channel of the unlicensed band. The method further includes receiving, at the access point, a plurality of responses from a plurality of user equipment acknowledging the single message in response to the single message.
Claims20
A method comprising:
- receiving, at a first access point over an unlicensed band, at least one of a first message indicating an intent to transmit data on a channel of the unlicensed band or a second message acknowledging the first message;
- determining whether the at least one of the first message or second message was transmitted by a second access point configured to coordinate transmissions with the first access point;
- and
- transmitting, by the first access point, a first signal on the unlicensed band during a same timeframe in which the second access point transmits a second signal on the unlicensed band based on determining the at least one of the first message or the second message was transmitted by the second access point.

A method comprising:
- determining at a first access point whether at least one of a first message or second message was transmitted by a second access point configured to coordinate transmissions with the first access point on an unlicensed band;
- and
- transmitting, by the first access point, a first signal on the unlicensed band during a same timeframe in which the second access point transmits a second signal on the unlicensed band based on determining the at least one of the first message or the second message was transmitted by the second access point.
An apparatus configured to transmit data over an unlicensed band, the apparatus comprising circuitry configured to:
- receive over the unlicensed band at least one of a first message indicating an intent to transmit data on a channel of the unlicensed band or a second message acknowledging the first message;
- determine whether the at least one of the first message or second message was transmitted by an access point configured to coordinate transmissions with the apparatus;
- and
- transmit, a first signal on the unlicensed band during a same timeframe in which the access point transmits a second signal on the unlicensed band based on determining the at least one of the first message or the second message was transmitted by the access point.
