Link adaptation in directional wireless networks
First Claim
Patent Images
1. An apparatus comprising:
- a transmitter to transmit packets over a beamformed wireless communication channel; and
a link adaptation module, wherein the link adaptation module initiates reforming the beamformed wireless communication channel to reestablish wireless communicationwherein the link adaptation module initiates reforming the beamformed wireless communication channel if the transmitter does not receive an acknowledgement (ACK) or block ACK packet from a receiving station in a predefined period of time (T), wherein the predefined period of time (T) is defined as;
T=((max_PPDU_size/MCS_AB)+SIFS+ACK)wherein max_PPDU_size is the maximum size of a PLCP (Physical Layer Convergence Procedure) protocol data unit (PHY PPDU), MCS_AB is the MCS used in the last successful fame exchange between the transmitting station and the receiving station, SIFS is short interframe space and ACK is the time taken to transmit an acknowledgement (ACK) frame.

5. An apparatus comprising:
-
a receiver to receive packets over a beamformed wireless communication channel; and a link adaptation module, wherein the link adaptation module switches the receiver into omni-receive mode to reestablish the communication channelwherein the link adaptation module initiates reforming the beamformed wireless communication channel to reestablish the communication channel and initiates reforming the beamformed wireless communication channel if the receiver does not receive a frame from a transmitting station in a predefined period of time (T), wherein the predefined period of time (T) is defined as;
T=((max_PPDU_size/MCS_AB)+SIFS+ACK)wherein max_PPDU_size is the maximum size of a PLCP (Physical Layer Convergence Procedure) protocol data unit (PHY PPDU), MCS_AB is the MCS used in the last successful fame exchange between the transmitting station and the receiving station, SIFS is short interframe space and ACK is the time taken to transmit an acknowledgement (ACK) frame. - View Dependent Claims (6)

7. A method comprising:
-
establishing a beamformed wireless communication channel between a transmitter station and a receiver station; and reestablishing the beamformed wireless communication channel between the transmitter station and the receiver station when communication is interrupted, wherein the receiver station enters an omni-receive mode after not receiving a frame for a predefined period of time (T), wherein the predefined period of time (T) is defined as;
T=((max_PPDU_size/MCS_AB)+SIFS+ACK)wherein max_PPDU_size is the maximum size of a PLCP (Physical Layer Convergence Procedure) protocol data unit (PHY PPDU), MCS_AB is the MCS used in the last successful fame exchange between the transmitting station and the receiving station, SIFS is short interframe space and ACK is the time taken to transmit an acknowledgement (ACK) frame. - View Dependent Claims (8, 9, 10, 11, 12)
