摘要:
A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.

A radio base station (eNB) according to the present invention includes: a management unit (11) configured to manage the number of mobile stations UE corresponding to each carrier; and a scheduling unit (12) configured to perform a scheduling processing to a scheduling-target mobile station (UE#A), in which the “CA” is set to be performed, in at least one of a primary carrier (carrier #1) and a secondary carrier (carrier #2) of the mobile station UE#A based on the number of mobile stations UE corresponding to each carrier.
摘要:
A radio base station (eNB) according to the present invention includes an aggregation level determination unit configured to determine an aggregation level based on CQI notified from a mobile station (UE), a control channel element assignment unit configured to assign a plurality of continuous CCE to a PDCCH addressed to the mobile station (UE), based on the determined aggregation level, and a resource assignment unit configured to assign resource element groups constituting the assigned CCE as a resource for the PDCCH addressed to the mobile station (UE). The control channel element assignment unit is configured to assign a plurality of continuous CCE to the PDCCH addressed to the mobile station (UE) based on an aggregation level changed by the aggregation level determination unit, when failing to assign CCE to the PDCCH addressed to the mobile station (UE).
