Abstract
According to the disclosure there provides a control channel element (CCE) allocation method comprising steps of: deciding an aggregation level of each of scheduled entities according to channel quality indicator (CQI) fed back from each of the scheduled entities; sorting in a list all the scheduled entities based on priority; obtaining at least two (CCE) allocation patterns each with preoccupation of (CCE) candidates by the scheduled entities by use of retrospective mechanism; selecting a (CCE) allocation pattern with maximum number of scheduled entities having preoccupied (CCE) candidates from the obtained at least two (CCE) allocation patterns; allocating (CCEs) to the scheduled entities based on the selected (CCE) allocation pattern.
