Abstract
An eNB 100-1 that performs radio communication by using the adaptive array control in the TD-LTE system: receives SRS utilized in the adaptive array control from a plurality of UEs 200; and performs an assignment for each subject downlink RBG, out of a plurality of downlink RBGs. The eNB assigns the subject downlink RBG to a UE 200 that transmitted a specific SRS that is SRS having the highest match rate in a frequency band with the subject downlink RBG, out of a plurality of SRSs received recently before the subject downlink RBG.
Claims5
A radio base station that performs radio communication by using adaptive array control, in a TDD radio communication system, comprising:
- a reception unit that receives an uplink reference signal utilized in the adaptive array control from a plurality of radio terminals;
- and
- a resource assignment unit that performs an assignment for each subject downlink radio resource, of the plurality of downlink radio resources, wherein
- the resource assignment unit assigns the subject downlink radio resource to a radio terminal that has transmitted a specific uplink reference signal that is an uplink reference signal having a highest match rate in frequency band with the subject downlink radio resource, of a plurality of uplink reference signals received recently before the subject downlink radio resource.
A communication control method in a radio base station that performs radio communication by using adaptive array control in a TDD radio communication system, comprising:
- a step of receiving an uplink reference signal utilized in the adaptive array control from a plurality of radio terminals;
- and
- a resource assignment step of performing an assignment for each subject downlink radio resource, of the plurality of downlink radio resources, wherein
- in the resource assignment step, the radio base station assigns the subject downlink radio resource to a radio terminal that has transmitted a specific uplink reference signal that is an uplink reference signal having a highest match rate in frequency band with the subject downlink radio resource, of a plurality of uplink reference signals received recently before the subject downlink radio resource.
