Method and apparatus for using direct wireless links and a central controller for dynamic resource allocation

Abstract

A method and apparatus may be used for short range multi-device communications. The method and apparatus may be used in personal area networks (PANs). The apparatus may transmit a security key using a non-penetrating wavelength. The apparatus may establish a secure communication and transmit data using a penetrating wavelength. The data transmission may be encrypted.

What is claimed is: 
     
         1 . A wireless transmit/receive unit (WTRU) comprising:
 a transmitter configured to:
 transmit a security key to another WTRU via a non-penetrating wavelength; and 
 transmit data to the another WTRU via a penetrating wavelength. 
   
     
     
         2 . The WTRU of  claim 1 , wherein the non-penetrating wavelength is ultraviolet (UV)-C. 
     
     
         3 . The WTRU of  claim 1 , wherein the penetrating wavelength is ultraviolet (UV)-A. 
     
     
         4 . The WTRU of  claim 1 , wherein the penetrating wavelength is a radio frequency (RF) wavelength. 
     
     
         5 . The WTRU of  claim 1 , wherein the data is encrypted. 
     
     
         6 . The WTRU of  claim 1 , wherein the security key is a private key. 
     
     
         7 . A wireless transmit/receive unit (WTRU) comprising:
 a receiver configured to:
 receive a security key from another WTRU via a non-penetrating wavelength; and 
 receive data from the another WTRU via a penetrating wavelength; and 
   a processor configured to decode the received data.   
     
     
         8 . The WTRU of  claim 7 , wherein the non-penetrating wavelength is ultraviolet (UV)-C. 
     
     
         9 . The WTRU of  claim 7 , wherein the penetrating wavelength is ultraviolet (UV)-A. 
     
     
         10 . The WTRU of  claim 7 , wherein the penetrating wavelength is a radio frequency (RF) wavelength. 
     
     
         11 . The WTRU of  claim 7 , wherein the data is encrypted. 
     
     
         12 . The WTRU of  claim 7 , wherein the security key is a private key. 
     
     
         13 . A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
 a transmitter configured to:
 transmit a security key to another WTRU via a non-penetrating wavelength; and 
 transmit data to the another WTRU via a penetrating wavelength. 
   
     
     
         14 . The method of  claim 13 , wherein the non-penetrating wavelength is ultraviolet (UV)-C. 
     
     
         15 . The method of  claim 13 , wherein the penetrating wavelength is ultraviolet (UV)-A. 
     
     
         16 . The method of  claim 13 , wherein the penetrating wavelength is a radio frequency (RF) wavelength. 
     
     
         17 . The method of  claim 13 , wherein the data is encrypted. 
     
     
         18 . The method of  claim 13 , wherein the security key is a private key.
