Spatial reuse in wireless communication

Abstract

A method of wireless communication may include monitoring, by a first device, a medium for frames in response to preparing to transmit a first frame to a second device. The method may also include while monitoring the medium and before transmitting the first frame, obtaining a second frame transmitted by a third device in the medium and adjusting a transmission of the first frame to the second device in the medium based on obtaining the second frame.

What is claimed is: 
     
         1 . A device comprising:
 hardware configured to reduce potential interference by adjusting a transmission protocol in view of an expected impact to an intended receiver of a transmission.   
     
     
         2 . The device of  claim 1 , wherein to reduce potential interference, the hardware is configured to intercept a frame over a communication medium, the intended receiver being associated with the frame, wherein the potential interference is determined in view of the frame being sent to the intended receiver. 
     
     
         3 . The device of  claim 1 , wherein to reduce potential interference, the hardware is configured to monitor for a response frame and, responsive to not identifying the response frame within a threshold amount of time, send a transmit frame to a particular device. 
     
     
         4 . The device of  claim 1 , wherein the adjustment to the transmission protocol is for a particular transmission for one or more devices other than the intended receiver. 
     
     
         5 . The device of  claim 1 , wherein the expected impact to the intended receiver includes a calculated path loss between a transmit device and the intended receiver of the transmission. 
     
     
         6 . The device of  claim 5 , wherein the transmit device is the device comprising the hardware configured to reduce the potential interference. 
     
     
         7 . The device of  claim 5 , wherein the transmission is sent by a secondary device that is not the transmit device and the transmit device and the intended receiver are not part of the same wireless network. 
     
     
         8 . The device of  claim 1 , wherein the adjusting the transmission protocol includes delaying transmission of a frame. 
     
     
         9 . The device of  claim 1 , wherein the adjusting the transmission protocol includes adjusting a power of transmission of a frame. 
     
     
         10 . The device of  claim 1 , wherein the adjusting the transmission protocol includes adjusting a frequency segment of a medium used for transmission of a frame. 
     
     
         11 . A method of wireless communication, the method comprising:
 reducing potential interference by adjusting a transmission protocol in view of an expected impact to an intended receiver of a transmission.   
     
     
         12 . The method of  claim 11 , wherein to reduce potential interference, the method includes intercepting a frame over a communication medium, wherein the intended receiver is associated with the frame and the potential interference is determined in view of the frame being sent to the intended receiver. 
     
     
         13 . The method of  claim 11 , wherein to reduce potential interference, the method includes monitoring for a response frame and, responsive to not identifying the response frame within a threshold amount of time, sending a transmit frame to a particular device. 
     
     
         14 . The method of  claim 11 , wherein the adjustment to the transmission protocol is for a particular transmission for one or more devices other than the intended receiver. 
     
     
         15 . The method of  claim 11 , wherein the expected impact to the intended receiver includes a calculated path loss between a transmit device and the intended receiver of the transmission. 
     
     
         16 . The method of  claim 15 , wherein the transmit device is configured to perform the method of  claim 15 . 
     
     
         17 . The method of  claim 15 , wherein the transmission is sent by a secondary device that is not the transmit device and the transmit device and the intended receiver are not part of the same wireless network. 
     
     
         18 . The method of  claim 11 , wherein the adjusting the transmission protocol includes delaying transmission of a frame. 
     
     
         19 . The method of  claim 11 , wherein the adjusting the transmission protocol includes adjusting a power of transmission of a frame. 
     
     
         20 . The method of  claim 11 , wherein the adjusting the transmission protocol includes adjusting a frequency segment of a medium used for transmission of a frame.
