To accommodate the realistic channel conditions better and thus improve the system throughput, 3GPP introduced the Physical Downlink Control Channel (PDCCH) in LTE. A downlink control information (DCI) message is generated and transmitted over the PDCCH. The User Equipment (UE) is required to perform blind decoding as it is not aware of the detailed control structure. However, blind decoding consumes a lot of UE's computational power, e.g. UE needs to do nearly 240 convolutional decodings on… CONTINUE READING
