The invention discloses a method and device for processing DCI blind detection data. The method includes: judging whether the energy sum of the current CCE is greater than the PDCCH channel noise energy threshold; The number of remaining signs, and determine the shift number of RE in the current CCE according to the number of redundant signs, so as to shift the RE according to the shift number; send the soft information corresponding to the shifted CCE to the coprocessor for predetermined processing ; After all the CCEs complete the predetermined processing, perform DCI blind detection on the CCEs according to different aggregation degrees. By using this method, it is solved that the code rate, power, and CCE space of the PDCCH channel scheduled by the base station in the prior art will change flexibly. These changing factors will bring a large amount of calculation and increase the complexity of DCI blind detection. This leads to a problem that higher energy consumption is required for DCI blind detection.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing DCI (Downlink Control Information, downlink control information) blind detection data. Background technique [0002] Compared with 2G / 3G technology, LTE (Long Term Evolution, long-term evolution) has many advantages such as high data rate, large cell capacity, coverage radius of 100km, and low system delay. The scheduling changes of the physical layer also become more frequent with the switching of application scenarios, which puts forward higher requirements on the processing stability of the terminal. [0003] The LTE system involves various configurations such as bandwidth, transmission mode, and carrier aggregation, and then combines with channel conditions such as base station distance and multipath to create many scenarios. Corresponding to these differences, the code rate, power, and CCE (Control Channel Element, Control Channel Element...
