Abstract
A wireless data reception method for receiving orthogonal frequency division multiplexing (OFDM) signal includes determining that an interfering signal is present, along with a serving cell signal, in the OFDM signal on the shared downlink channel, determining an estimate of a transmission structure of the received interfering signal, wherein the transmission structure is defined by a plurality of transmission parameters, classifying the estimate of the transmission structure as belonging to a subgroup from a plurality of possible subgroups in a dynamic order, estimating, in a priority order, at least some of the plurality of transmission parameters of the estimate of the transmission structure, and performing further receiver-side processing of the serving cell signal by subtracting contribution of the interfering signal from the OFDM signal based on the estimate of the transmission structure and a result of the estimating step.
