USER DATA RATE ESTIMATION DEVICE, USER DATA RATE ESTIMATION METHOD, AND PROGRAM
A user data rate estimation device acquires a reception power in a user, and receives input of information regarding a communication environment of the user. Next, the device calculates a wireless resource to be allocated to the user on the basis of information regarding a bandwidth, a scheduling method, and the number of users included in the information regarding the communication environment, calculates an overhead on the basis of information regarding a communication standard, a frequency band, and a bandwidth included in the information regarding the communication environment, and determines a communication mode on the basis of the reception power or communication quality information converted from the reception power. Then, the device calculates a user data rate on the basis of the wireless resource, the overhead, the communication mode, and information regarding the number of spatial streams included in the information regarding the communication environment.
