METHOD AND DEVICE FOR ALLOCATING CONTROL CHANNEL RESOURCES

摘要

A method and device for allocating control channel resources are provided in the present invention. The method includes that: a base station calculates the common space control channel element CCE, allocates the CCE for the downlink control information DCI which is waiting for allocating common space CCE, and maps the allocated CCE to the physical downlink control channel PDCCH; the base station calculates the CCE aggregation level, and extracts the value of the CCE aggregation level in order to calculate the CCE required by the allocation; the base station allocates CCE for the DCI of each scheduling user equipment UE, and maps the allocated CCE to the PDCCH. The device includes a common space CCE allocating unit, a CCE master control unit, a CCE allocating unit and a mapping disposal unit. The method and device for allocating control channel resources of the invention are capable of increasing the success ratio of the CCE allocation and the utilization ratio of the CCE.
