Method and wireless communication device for conveying neighbor access point information

Abstract

A method for one of a plurality access points (APs) of a wireless communication system to convey neighbor information to a station is disclosed. The method includes transmitting a compact information of at least one neighbor AP; wherein the compact information is transmitted in a frame and the compact information is used for scanning.

What is claimed is: 
     
         1 . A method for one of a plurality of access points (APs) of a wireless communication system to convey neighbor AP information to a station, comprising:
 an AP of the plurality of APs transmitting a compact information of at least one neighbor AP to the station;   wherein the compact information is used for scanning and specifying a difference information between the one of the plurality of APs and the at least one neighbor AP.   
     
     
         2 . The method of  claim 1 , wherein the difference information is obtained from comparison of basic service set (BBS) Load, BBS Average Access Delay or BSS Available Admission Capacity between the one of the plurality of APs and the at least one neighbor AP. 
     
     
         3 . The method of  claim 1 , wherein the compact information specifies a compressed information for the at least one neighbor AP. 
     
     
         4 . The method of  claim 3 , wherein the compressed information is obtained from selecting different units or quantization levels. 
     
     
         5 . The method of  claim 1 , wherein the compact information is received in a frame. 
     
     
         6 . The method of  claim 5 , wherein the frame is a Beacon frame, a Probe Response frame, or a Measurement Pilot frame. 
     
     
         7 . A method for a station to receive neighbor access point (AP) information from one of a plurality APs of a wireless communication system, comprising:
 the station receiving a compact information of at least one neighbor AP;   wherein the compact information is used for scanning and specifying a difference information between the one of the plurality of APs and the at least one neighbor AP.   
     
     
         8 . The method of  claim 7 , wherein the difference information is obtained from comparison of basic service set (BBS) Load, BBS Average Access Delay or BSS Available Admission Capacity between the one of the plurality of APs and the at least one neighbor AP. 
     
     
         9 . The method of  claim 7 , wherein the compact information specifies a compressed information for the at least one neighbor AP. 
     
     
         10 . The method of  claim 9 , wherein the compressed information is obtained from selecting different units or quantization levels. 
     
     
         11 . The method of  claim 7 , wherein the compact information is received in a frame. 
     
     
         12 . A communication device for a wireless communication system, comprising:
 a central processing unit; and   a storage device coupled to the central processing unit for storing a programming code, wherein the programming code instructs the central processing unit to process a method for a station to receive neighbor access point (AP) information from one of a plurality APs of a wireless communication system, the method comprising:
 receiving a compact information of at least one neighbor AP; 
 wherein the compact information is used for scanning and specifying a difference information between the one of the plurality of APs and the at least one neighbor AP. 
   
     
     
         13 . The communication device of  claim 12 , wherein the difference information is obtained from comparison of basic service set (BBS) Load, BBS Average Access Delay or BSS Available Admission Capacity between the one of the plurality of APs and the at least one neighbor AP. 
     
     
         14 . The communication device of  claim 12 , wherein the compact information specifies a compressed information for the at least one neighbor AP. 
     
     
         15 . The communication device of  claim 14 , wherein the compressed information is obtained from selecting different units or quantization levels. 
     
     
         16 . The communication device of  claim 12 , wherein the compact information is received in a frame.
