Method and apparatus for reliably communicating information packets in a wireless communication network
First Claim
1. A method for a first wireless device to reliably communicate information packets to a second wireless device in a wireless communication network, the method comprising the steps of:
- transmitting a first information packet to the second wireless device over a first wireless communication channel;
determining whether the first information packet was successfully received by the second wireless device;
retransmitting the first information packet to the second wireless device over a second wireless communication channel in the event that the first information packet was not successfully received by the second wireless device; and
transmitting at least a second information packet to the second wireless device over the first wireless communication channel, wherein the first information packet and the at least a second information packet form a sequence of information.

Abstract
A wireless communication network (100) employs a method and apparatus for reliably communicating information packets in the network. A first wireless device (101) in the network transmits an information packet to a second wireless device (e.g., 102) in the network over a first wireless communication channel (403, 404). The first device then determines whether the information packet was successfully received (e.g., received without errors) by the second device. If the information packet was not successfully received, the first device retransmits the information packet to the second device over a second wireless communication channel (405, 406). In addition, and preferably substantially contemporaneous with retransmission of the first information packet, the first device transmits a second information packet to the second device over the first channel in an effort to communicate an information sequence to the second device without delays typically associated with use of a reliable protocol.

12. A method for a first wireless device to reliably communicate information packets to a second wireless device in a wireless local area network, the method comprising the steps of:
-
transmitting a first information packet to the second wireless device over a first wireless communication channel, the first information packet including real-time information;
transmitting packetized, non-real-time information to at least one of the second wireless device and a third wireless device over a second wireless communication channel;
determining whether the first information packet was successfully received by the second wireless device;
in the event that the first information packet was not successfully received by the second wireless device, temporarily interrupting transmission of the packetized, non-real-time information over the second wireless communication channel;
retransmitting the first information packet to the second wireless device over the second wireless communication channel; and
substantially contemporaneous with retransmission of the first information packet, transmitting a second information packet to the second wireless device over the first wireless communication channel, wherein the first information packet and the second information packet form a sequence of information. - View Dependent Claims (13, 14)

15. A method for a first wireless device to reliably receive information packets from a second wireless device in a wireless communication network, the method comprising the steps of:
-
receiving a first information packet from the second wireless device over a first wireless communication channel;
informing the second wireless device as to whether the first information packet was successfully received;
receiving the first information packet from the second wireless device over a second wireless communication channel in the event that the first information packet was not successfully received previously; and
receiving at least a second information packet from the second wireless device over the first wireless communication channel, wherein the first information packet and the at least a second information packet form a sequence of information. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A wireless base transceiver station system comprising:
-
a program memory that stores operating instructions for performing particular functions;
a controller that executes the operating instructions stored in the program memory to perform at least the following functions;
allocate wireless communication channels in support of communicating information packets to wireless electronic devices, control transmission of the information packets to the wireless electronic devices, and determine, based on at least one of information received and lack of information received from a first wireless electronic device, whether a first information packet transmitted to the first wireless electronic device was successfully received by the first wireless electronic device;
a transmitter, responsive to the controller, that transmits the first information packet to the first wireless electronic device over a first wireless communication channel, retransmits the first information packet to the first wireless electronic device over a second wireless communication channel in the event that the first information packet was not successfully received by the first wireless electronic device, and transmits at least a second information packet to the first wireless electronic device over the first wireless communication channel, wherein the first information packet and the at least a second information packet form a sequence of information; and
a receiver, operably coupled to the controller, that receives information from the wireless electronic devices. - View Dependent Claims (24)

25. A wireless device comprising:
-
a receiver that receives an initial transmission of a first information packet from a second wireless device over a first wireless communication channel, receives a retransmission of the first information packet over a second wireless communication channel in the event that the initial transmission of the first information packet was not acceptable, and receives at least a second information packet from the second wireless device over the first wireless communication channel, the first information packet and the at least a second information packet forming a sequence of information;
a program memory that stores operating instructions for performing particular functions;
a processor, operably coupled to the receiver and the program memory, that executes the operating instructions stored in the program memory to perform at least the following functions;
determine whether the initial transmission of the first information packet received from the second wireless device is acceptable;
inform the second wireless device as to whether the initial transmission of the first information packet is acceptable; and
process the first information packet and the at least a second information packet to reconstruct the sequence of information upon successful reception of the first information packet and the at least a second information packet; and
a transmitter, responsive to the processor, that transmits information to the second wireless device. - View Dependent Claims (26, 27, 28, 29)
