Title:
通信システム
Document Type and Number:
Japanese Patent JP6399838
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a communication system capable of reducing the power consumption of a mobile station in semi-persistent scheduling (SPS).SOLUTION: A communication system allows a mobile station and a base station to communicate with each other by making good use of Dynamic scheduling and SPS. The base station when communicating with the mobile station by Dynamic scheduling transmits an SPS activation command validating the SPS to the mobile station. Once receiving the SPS activation command, the mobile station starts communicating with the base station by SPS, and demodulates data of a first frequency band (f11-f12) in which radio sources allocated together by SPS are included, but does not demodulate data of a second frequency band (f1-f11 and F12-f2) other than the first frequency band.SELECTED DRAWING: Figure 1
