Abstract

This disclosure is directed to a repeater and base station control device implemented in a wireless communication system. The repeater includes a control unit capable of detecting signals sent from various base stations in the wireless communication system. In accordance with this disclosure, the repeater identifies a set of base stations that it can detect, and then sends information indicative of the set of base stations that the repeater can detect to a specific base station that gets repeated by the repeater. In this manner, the repeater can be used to help assess network topology. The base station control device receives the information from the base station and can use the information to update a neighbor list.

Claims

receiving information in a wireless communication system from a repeater through a base station of a set of base stations, the information being indicative of signals of said set of base stations detectable by said repeater, wherein the information identifies a set of phase offsets detected from the signals of the set of base stations; and

updating a neighbor list based on the received information.

2. The method of claim 1, further comprising initiating transmission of the updated neighbor list to one or more subscriber units of the wireless communication system.

3. The method of claim 1, wherein the information includes identification codes detected from the signals of the set of base stations.
