Abstract:
1. A method for allocating a Control Channel Element (CCE), comprising: determining a CCE aggregation level, by a network, according to a mapping relationship between a Channel Quality Identity (CQI) and a Physical Downlink Control Channel (PDCCH) code rate; and allocating the CCE resource according to the CCE aggregation level by the network, wherein the step of determining the CCE aggregation level by the network according to the mapping relationship comprises: selecting a corresponding first PDCCH code rate for public Downlink Control Information (DCI), by the network, according to the mapping relationship and a minimum wideband CQI of all the activated User Equipments (UEs) in a cell at a current Transmission Time Interval (TTI); and selecting a corresponding first CCE aggregation level from a CCE aggregation level set {4, 8} for the public DCI at the current TTI, by the network, according to the corresponding first PDCCH code rate, wherein the first CCE aggregation level corresponds to the first PDCCH code rate.
