Abstract
A method includes transmitting, at an access point configured to transmit data over an unlicensed band, a message to user equipment. The user equipment transmits to the access point an acknowledgement message indicating whether data provided within the message was successfully received in response to the message. The method further includes determining, at the access point, whether a buffer associated with the user equipment is empty. The method further includes retransmitting, from the access point to the user equipment, the message in response to determining the buffer of the user equipment is empty.
