Claim Text:
1. A method performed in a user equipment operating in a serving cell of a communication system, the method comprising: generating an initial estimate of interference with respect to serving cell reference signals received by the user equipment from the serving cell, said initial estimate of interference including the effects of one or more neighbor cell reference signals that interfere with reception of the serving cell reference signals at the user equipment; estimating an interference contribution of each neighbor cell reference signal to the initial estimate of interference, based on an estimating a channel corresponding to the neighbor cell reference signal; canceling the estimated interference contributions of the one or more neighbor cell reference signals from the initial estimate of interference, to thereby obtain a second estimate of interference that accounts for the cancellation of the estimated interference contributions; evaluating a consistency of the second estimate of interference; and using the second estimate of interference for at least one of demodulating serving cell data signals and estimating serving cell signal quality, responsive to determining that the second estimate of interference is consistent, and using the initial estimate of interference instead of the second estimate of interference, responsive to determining that the second estimate of interference is not consistent.
