REFERENCE SIGNAL PATTERN DETECTION IN WIRELESS TRANSMISSIONS
First Claim
1. A method comprising:
- receiving, at a mobile device, one or more wireless signals transmitted from a wireless node, wherein the wireless node is 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;
deriving, at the mobile device, 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, at the mobile device, 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.

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.

13. A mobile wireless device comprising:
-
a transceiver configured to; receive one or more wireless signals transmitted from a wireless node, wherein the wireless node is 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; and one or more processors, coupled to the transceiver, configured to; derive, 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 determine 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
