Patent ID: 8755345

Claim:
A method for allocating resources comprising: a base station calculating a number of Physical Downlink Control Channel (PDCCH) aggregation degree groups based on a maximum number of Control Channel Element (CCE) resources which can be occupied by PDCCH in a subframe, wherein a largest PDCCH aggregation degree is taken as a number of CCE resources per PDCCH aggregation degree group; the base station setting at least one aggregation degree group in middle of total PDCCH aggregation degree groups as a common search space; the base station determining PDCCH aggregation degree groups where a UE specified search space is located using a space division function based on User Equipment (UE) information and common information; and the base station searching a location of the UE specified search space in determined PDCCH aggregation degree groups where the UE specified search space is located and performing PDCCH resource allocation; wherein the step of determining the PDCCH aggregation degree group where the UE specified search space is located using the space division function comprises: the base station dividing the total PDCCH aggregation degree groups into a plurality of sub-spaces, wherein each sub-space includes a plurality of PDCCH aggregation degree groups; the base station determining sub-spaces where the UE specified search space is located using a sub-space division function, based on identification information of UE, a time slot number and a subframe number; and the base station determining PDCCH aggregation degree groups within the sub-spaces where the UE specified search space is located using a group division function.
