摘要：Techniques to determine the position of a terminal under the coverage of arepeater in a wireless communication system. In an aspect, an identification code is

transmitted for each repeater and used by the terminal (or a PDE) to unambiguouslyidentify the repeater. The identification codes for the repeaters in the system can beimplemented with PN sequences at defined offsets that are specifically reserved forrepeater identification. In another aspect, the identification code for each repeater istransmitted using a spread-spectrum signal designed to have minimal impact on theperformance of the system and to be recoverable by the terminal in similar manner asfor a forward modulated signal. In this way, no additional hardware is required for theterminal to recover the identifier signal. In one specific design, the spread spectrumidentifier signal is generated in accordance with and conforms to the IS-95 CDMAstandard.
