Base station, communication system, communication control method, and program

摘要

A base station that executes scheduling for an uplink and scheduling for a downlink per subframe to communicate with mobile stations. The base station comprises: a control information item number estimation unit that estimates the number of control information items usable for the uplink and the number of control information items usable for the downlink per subframe; and a scheduling unit that executes scheduling for the uplink and scheduling for the downlink per subframe by using a number of control information items usable for the uplink and a number of control information items usable for the downlink, the numbers estimated by the control information item number estimation unit.

1. A base station that executes scheduling for an uplink and scheduling for a downlink per subframe to communicate with mobile stations, the base station comprising:
a control information item number estimator configured to estimate the number of control information items usable for the uplink and the number of control information items usable for the downlink per subframe; a scheduler configured to execute scheduling for the uplink and scheduling for the downlink per subframe by using a number of control information items usable for the uplink and a number of control information items usable for the downlink, the numbers estimated by the control information item number estimator; a mobile station information manager configured to manage information about uplink data and downlink data for each of the mobile stations; and a common control information manager configured to manage common control information, wherein the control information item number estimator is further configured to estimate the number of control information items usable for the uplink and the number of control information items usable for the downlink per subframe by using information from the mobile station information manager and common control information from the common control information manager; wherein the scheduler comprises: an uplink scheduler configured to execute scheduling for the uplink per subframe by using the number of control information items usable for the uplink estimated by the control information item number estimator and information about uplink data managed by the mobile station information manager; and a downlink scheduler configured to execute scheduling for the downlink per subframe by using the number of control information items usable for the downlink estimated by the control information number estimator and information about downlink data managed by the mobile station information manager, and wherein, after receiving scheduling information representing results of scheduling for the downlink from the downlink scheduler, the uplink scheduler executes scheduling for the uplink, and wherein the control information item number estimator is further configured to estimate the number of control information items usable for the uplink based at least on a count of mobile stations, and wherein the estimated number of control information items usable for the uplink is proportional to the count of mobile stations.
