Document Type and Number:
Japanese Patent JP6844978
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique which can reduce the data amount of radio signals transmitted between a user device and a base station.SOLUTION: In a mobile communication system including the base station and the user device, the user device which communicates with the base station includes: PDCP layer processing means having storage means to receive and store by a plurality of acknowledgement signals transmitted to the base station; and RLC layer processing means which transmits to the PDCP layer processing means a signal transmission permission signal, which indicates that the transmission of an uplink signal is possible. The PDCP layer processing means, when receiving the signal transmission permission signal, transmits to the RLC layer processing means a plurality of acknowledgement signals, including a last received acknowledgement signal, among the plurality of acknowledgement signals stored in the storage means.SELECTED DRAWING: Figure 5
