Title: REFERENCE SIGNAL PATTERN DETECTION IN WIRELESS TRANSMISSIONS
Abstract:
Disclosed are implementations that include a method, generally performed at a mobile device, including receiving one or more wireless signals transmitted from a wireless node, with the wireless node being configured to operate in at least a first mode of operation to transmit wireless transmissions comprising one or more subframes configured according to a pre-determined first pattern of cell-specific reference signals (CRS) for the wireless node. The method also includes deriving, based on the received one or more wireless signals, at least one resultant signal attribute indicative of an actual CRS pattern for the received one or more wireless signals, and determining whether the at least one resultant signal attribute derived based on the received one or more wireless signals deviates from a corresponding expected at least one signal attribute associated with wireless signals including cell-specific reference signals produced according to the pre-determined first pattern of CRS.
