Abstract
Systems and methods for facilitating communication between communication devices are provided. An exemplary method includes: sending an indication signal by a second communication device to a first communication device, the indication signal corresponding to a request to receive buffered data from the first communication device; and sending a data frame by the second communication device to the first communication device.
Claims17
A method comprising:
- determining, at a communication device, a presence of data for transmission to an access point in an uplink data frame;
- switching from a power save mode to an active mode and sending an unsolicited indication signal to the access point in response to determining the presence of data for transmission to the access point,
- wherein the unsolicited indication signal indicates that the communication device is prepared to receive buffered data from the access point,
- wherein the unsolicited indication signal is sent prior to the sending of an uplink data frame, and
- wherein the unsolicited indication signal is not sent in response to a beacon signal transmitted by the access point;
- and
- sending the uplink data frame to the access point in response to receiving a first acknowledgement from the access point, wherein the first acknowledgment indicates that the access point received the unsolicited indication signal.
4 more elements
A method comprising:
- receiving an unsolicited indication signal at an access point,
- wherein the unsolicited indication signal indicates that a communication device is prepared to receive buffered data from the access point,
- wherein the unsolicited indication signal is received prior to an uplink data frame, and
- wherein the unsolicited indication signal is not received in response to a beacon signal transmitted by the access point;
- sending a first acknowledgment to the communication device, wherein the first acknowledgement indicates that the access point received the unsolicited indication signal;
- receiving the uplink data frame from the communication device
- transmitting a second acknowledgement to the communication device, wherein the second acknowledgment indicates that the access point received the uplink data frame;
- and
- transmitting the buffered data to the communication device.
6 more elements
A communication device comprising:
- an signal generator configured to generate an unsolicited indication signal, wherein the unsolicited indication signal indicates that the communication device is prepared to receive buffered data from an access point;
- a communication interface configured to communicate with the access point;
- and
- program logic stored in data storage and executable by at least one processor to:
- cause the communication device to switch from a power save mode to an active mode and to send the unsolicited indication signal to the access point in response to determining the presence of data for transmission to the access point in an uplink data frame;
- wherein the unsolicited indication signal is sent prior to the uplink data frame, and
- wherein the unsolicited indication signal is not sent in response to a beacon signal transmitted by the access point;
- and
- cause the communication interface to send the uplink data frame to the access point in response to receiving a first acknowledgement from the access point, wherein the first acknowledgment indicates that the access point received the unsolicited indication signal.
6 more elements
A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising:
- instructions for determining, at a communication device, a presence of data for transmission to an access point in an uplink data frame;
- instructions for switching from a power save mode to an active mode and sending an unsolicited indication signal to the access point in response to determining the presence of data for transmission to the access point,
- wherein the unsolicited indication signal indicates that the communication device is prepared to receive buffered data from the access point,
- wherein the unsolicited indication signal is sent prior to the sending of an uplink data frame, and
- wherein the unsolicited indication signal is not sent in response to a beacon signal transmitted by the access point;
- and
- instructions for sending the uplink data frame to the access point in response to receiving a first acknowledgement from the access point, wherein the first acknowledgment indicates that the access point received the unsolicited indication signal.
