An Improved Physical Downlink Control Channel De-Resource Mapping Method in Long Term Evolution Systems

Abstract:

In TD-LTE (Time Division-Long Term Evolution) system, Resource Element Group (REG) is the unit of de-resource mapping for Physical Downlink Control Channel (PDCCH), due to the reference signal should be considered, which lead to the large calculation. To solve this problem, a modified method is proposed in this paper to reduce the cycles of de-resource mapping. Calculation and simulation reveal that this scheme can reduce the calculation significantly. At the same time, the feasibility and effectiveness of this modified method have been verified.
