Method, system and apparatus for detecting a position of a terminal in a network

A wireless base station in a wireless system operable to perform communication with a wireless terminal via a plurality of communication channels, said wireless base station comprising:

• a position detection signal generator generating signals for position detection;
• a transmitter setting transmission parameters for said signals for position detection with a second preamble and signals for user data with a first preamble;
• and
• an antenna transmitting signals for position detection and signals for user data to said wireless terminal, and signals for position detection to at least one of other wireless base stations,
• wherein said transmitter sets the transmission parameters so that a length of said second preamble is longer than a length for transmitting and receiving said signals for user data of said first preamble,
• said wireless terminal transmits and receives signals for user data with a third preamble, and transmits and receives signals for position detection with a fourth preamble having a length that is longer than a length of said third preamble,
• said wireless base stations and said wireless terminal transmit signals for position detection to said wireless terminal and at least one of said other wireless base stations, and
• at least one of said other wireless base stations receives signals for position detection from said wireless base stations with the second preamble and from said wireless terminal with the fourth preamble.
