Claim Text:
1. A method to reduce resource consumption by a wireless communication device when decoding a physical downlink control channel (PDCCH) in a subframe, the method comprising: at the wireless communication device: obtaining a first channel estimate based on a first orthogonal frequency-division multiplexing (OFDM) symbol of the subframe; demodulating a first set of one or more PDCCH OFDM symbols contained in the subframe based on the first channel estimate; obtaining a second channel estimate based on a second OFDM symbol of the subframe before demodulating a second set of one or more PDCCH OFDM symbols contained in the subframe; and demodulating the second set of one or more PDCCH OFDM symbols based on both the first channel estimate and the second channel estimate.
