摘要： PROBLEM TO BE SOLVED: To allow a base station to control an actual communication rate of a user device in accordance with an upper rate of each user informed by a core network.SOLUTION: A base station allocates radio resources to a target user to calculate an available data amount for each user based on scheduling metric calculated for each scheduling target user. When the radio resources are allocated to a user, a data amount (D) to be transmitted by the allocated radio resources is subtracted from an available data amount (D) for the user. For every control period (T), the available data amount (D) for each user in a cell is updated to a data amount (min((D+D), D) which is equal to or less than a reference data amount. Based on the available data amount for each user, the scheduling target user is selected.

摘要： PROBLEM TO BE SOLVED: To shorten pull-in time without using a training signal (reference signal) in an adaptive equalizer. SOLUTION: When the adaptive equalizer formed of combining a carrier recovery circuit (CR) 12 with a determination feedback equalizer (DFE) 16 performs the pull-in, the tap coefficient of the DFE is updated by means of a CMA Algorithm (Godard) without affecting the phase rotation of a carrier in a pull-in start step, and simultaneously a carrier recovery is staered by using phase error detection limiting the determination range of the carrier recovery circuit. After converging a carrier recovery and sufficiently reducing equalization error power, a pull-in completion step switches the above carrier recovery to a carrier recovery, using determination range-free phase error detection, and switches DFE tap replacement to the algorithm from the CMA with determination orientation (LMS).

摘要： PROBLEM TO BE SOLVED: To allow a base station to secure its resources for user terminals registered therewith when the base station is configured to accept connections from the user terminals registered therewith as well as user terminals not registered therewith.SOLUTION: A base station has a call-connection acceptance determination unit, a redirection-setting unit, and a notification unit. When the base station receives a call-connection request signal from a user terminal, the call-connection acceptance determination unit determines, on the basis of the amount of resources in use by the base station, whether or not the call-connection request from the user terminal can be accepted. If the call-connection acceptance determination unit determines that the call-connection request from the user terminal cannot be accepted, the redirection-setting unit sets another base station to which the user terminal is to be redirected. The notification unit notifies the user terminal of information representing the other base station.
