The method for enhancing an X2 interface proxy comprises: triggering an X2 proxy to relocate from a first node to a second node, or triggering to set up an X2 interface between a third node and the second node; and using the second node as an X2 proxy of the third node and a base station adjacent to the third node.

A method and apparatus for transmitting an indication in a wireless communication system is provided. A relay node (RN) transmits an indication which indicates that the RN is either a fixed relay node or a mobile relay node, and receives initial parameters from an operation, administration, and maintenance (OAM) according on the indication.

A wireless local area network (WLAN) includes a server and receiver, which includes a radio frequency (RF) front-end circuit that receives wireless signals from the mobile nodes within the WLAN and detects baseband signals. A signal waveform detector edge detects a signal waveform and generates a trigger signal indicative of the modulation type, data format and time-of-arrival (TOA) information of a desired signal to be captured. A baseband processor receives the trigger signal from the signal waveform detector and captures the desired signal. A system controller is connected to the baseband processor and configures the baseband processor for processing the desired signal and obtaining message data and signal metrics that are transferred to the system controller to be communicated outbound from the receiver as a client to the server.
