Abstract

A method for managing shared wireless communications in a wireless communication network is provided. The wireless communications network includes at least one cooperative device and at least one non-cooperative device. The method includes the steps of monitoring, by the at least one cooperative device, a selected channel of a shared spectrum of the wireless communication network, detecting, by the at least one cooperative device, a presence of a transmission from the non-cooperative device within a measurable vicinity of the cooperative device, and responding, by the at least one cooperative device, to the detected presence of the transmission from the non-cooperative device.

What is claimed is: 
     
         1 . A method for managing shared wireless communications in a wireless communication network including at least one cooperative device and at least one non-cooperative device, the method comprising the steps of:
 monitoring, by the at least one cooperative device, a selected channel of a shared spectrum of the wireless communication network;   detecting, by the at least one cooperative device, a presence of a transmission from the non-cooperative device within a measurable vicinity of the cooperative device; and   responding, by the at least one cooperative device, to the detected presence of the transmission from the non-cooperative device.   
     
     
         2 . The method of  claim 1 , wherein the at least one cooperative device utilizes a distributed access protocol relating to one or more of Wi-Fi, Bluetooth, and Zigbee technologies. 
     
     
         3 . The method of  claim 1 , wherein the at least one non-cooperative device utilizes one or more of a long term evolution protocol and an unlicensed long term evolution protocol. 
     
     
         4 . The method of  claim 1 , wherein the step of detecting comprises a substep of employing carrier sense multiple access with collision avoidance. 
     
     
         5 . The method of  claim 1 , wherein the step of detecting comprises a substep of identifying operational information of the transmission from the non-cooperative device. 
     
     
         6 . The method of  claim 5 , wherein the substep of identifying determines that the transmission from the non-cooperative device is an aggressive transmission. 
     
     
         7 . The method of  claim 6 , wherein the step of responding comprises one or more of the substeps of reporting the detected presence of the aggressive transmission, calculating operational parameters of the aggressive signal, and adapting a polite transmission of the at least one cooperative device based on the identified operational information of the aggressive transmission. 
     
     
         8 . The method of  claim 7 , wherein the substep of adapting further comprises one or more of the additional substeps of maintaining a legacy protocol of the polite transmission, avoiding a frequency domain of the aggressive transmission, scheduling the polite transmission to transmit within periods when a duty cycle of the aggressive transmission is off, increasing an output power of the polite transmission, adjusting a throughput of the polite transmission, and transmit redundant data relating to the polite transmission. 
     
     
         9 . The method of  claim 8 , wherein, when implementing the substep of maintaining, the substep of calculating first determines that performance loss of the polite transmission, in the presence of the aggressive transmission, is unlikely. 
     
     
         10 . The method of  claim 8 , wherein, when implementing the substep of scheduling, the substep of calculating first calculates the duty cycle of the aggressive transmission from the operational parameters. 
     
     
         11 . The method of  claim 10 , wherein the substep of scheduling comprises the further substep of synchronizing a contention window of the polite transmission to conform with an off state of the duty cycle of the aggressive transmission. 
     
     
         12 . The method of  claim 8 , wherein the substep of avoiding comprises the further substep of switching a transmission channel of the polite transmission to a different transmission channel that does not contain the aggressive transmission. 
     
     
         13 . The method of  claim 8 , wherein the substep of increasing the output power comprises the further substep generating a sufficient signal to noise ratio for the polite transmission to overcome an increased noise level in the selected channel resulting from the presence of the aggressive transmission. 
     
     
         14 . The method of  claim 8 , wherein the substep of adjusting the throughput comprises the further substep reducing the transmission speed of the polite transmission. 
     
     
         15 . A wireless communications system, comprising:
 at least one cooperative electronic device including a processor and a transceiver;   at least one non-cooperative electronic device;   an access point configured to wirelessly send and receive polite transmission data to and from the at least one cooperative electronic device, respectively; and   a communications node configured to wirelessly send and receive aggressive transmission data to and from the at least one non-cooperative electronic device, respectively,   wherein the transceiver is configured to monitor a selected channel of a shared spectrum of the wireless communications system and identify the presence of the aggressive transmission data within a proximity of the at least one cooperative electronic device.   
     
     
         16 . The system of  claim 15 , wherein the at least one cooperative device comprises a Wi-Fi device. 
     
     
         17 . The system of  claim 15 , wherein the at least one non-cooperative device comprises an unlicensed long term evolution user equipment.
