Network allocation

Abstract

Included are embodiments for network allocation. More specifically, one embodiment of a method includes receiving, at a first communications device, without a prior RTS signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration and sending a second CTS signal, from the first communications device, to the second communications device.

         21 . A method, comprising:
 receiving, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, the first CTS signal indicating a data exchange duration, wherein a non-resetting network allocation vector (NAV) is set by at the first communications device that overrides a resetting NAV at the first communications device; and   receiving, at the first communications device, a request to send (RTS) signal that directly follows the first CTS signal and that is addressed to the second communications device, the RTS signal indicating a data exchange duration that does not exceed the data exchange duration of the first CTS signal.   
     
     
         22 . The method of  claim 21 , further comprising sending, from the first communications device, a second CTS signal. 
     
     
         23 . The method of  claim 22 , wherein the RTS signal is addressed to the first communications device, the RTS signal indicating a data exchange duration that does not exceed the data exchange duration of the first CTS signal. 
     
     
         24 . The method of  claim 21 , further comprising sending, by the first communications device payload data to the second communications device. 
     
     
         25 . The method of  claim 21 , wherein the non-resetting NAV has a longer associated duration than an associated duration of the resetting NAV. 
     
     
         26 . The method of  claim 25 , wherein the first CTS is configured at a first modulation and the second CTS is configured at a second modulation. 
     
     
         27 . The method of  claim 21 , wherein the non-resetting NAV is configured to be non-resetting at a plurality of other communications devices. 
     
     
         28 . A computer readable medium, comprising:
 first receiving logic configured to receive, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, the CTS signal indicating a data exchange duration, the first receiving logic configured to set a resetting network allocation vector (NAV) to be non-resetting;   second receiving logic configured to receive, at the first communications device, a request to send (RTS) signal that directly follows the first CTS from the second communications device, the RTS directly following the first CTS signal is addressed to the first communications device, the RTS indicating a data exchange duration that does not exceed the data exchange duration of the first CTS.   
     
     
         29 . The computer readable medium of  claim 28 , further comprising second receiving logic configured to receive, at the first communications device, a request to send (RTS) signal that directly follows the first CTS signal. 
     
     
         30 . The computer readable medium of  claim 29 , wherein the RTS is addressed at the first communications device, the RTS indicating a data exchange duration that does not exceed the data exchange duration of the CTS. 
     
     
         31 . The computer readable medium of  claim 28 , further comprising third receiving logic configured to receive, by the first communications device payload data from the second communications device. 
     
     
         32 . The computer readable medium of  claim 28 , further comprising second sending logic configured to send a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal. 
     
     
         33 . The computer readable medium of  claim 32 , wherein the second CTS is configured at a first modulation and the third CTS is configured at a second modulation. 
     
     
         34 . The computer readable medium of  claim 28 , wherein the first receiving logic sets the resetting NAV to be non-resetting if the data exchange duration is longer than a default data exchange duration of the resetting NAV. 
     
     
         35 . A system, comprising:
 means for receiving, at a first communications device, without a prior request to send (RTS) signal being sent, a first clear to send (CTS) signal from a second communications device, addressed to the first communications device, the CTS signal indicating a data exchange duration: and   means for sending a second CTS signal, from the first communications device, to the second communications device,   wherein a network allocation vector (NAV) at the first communications device is set to non-resetting prior to receiving a RTS signal.   
     
     
         36 . The system of  claim 35 , further comprising means for receiving, at the first communications device, a request to send (RTS) signal that directly follows the first CTS signal. 
     
     
         37 . The system of  claim 36 , wherein the RTS is addressed to the first communications device, the RTS indicating a data exchange duration that does not exceed the data exchange duration of the CTS. 
     
     
         38 . The system of  claim 35 , further comprising means for receiving, by the first communications device payload data from the second communications device. 
     
     
         39 . The system of  claim 35 , further comprising means for sending a third CTS signal from the first communications device to the second communications device, the third CTS signal being sent directly after the second CTS signal.
