    Abstract: The base station notifies each mobile station of reporting conditions for causing the mobile station to transmit a measurement report containing measurement results of the radio quality. The reporting conditions include a first reporting condition and a second reporting condition in which the offset value added to the measurement result of the radio quality is greater than that of the first reporting condition and in which the guard time, that is a time from when the reporting condition is satisfied until the measurement report is transmitted, is shorter than that of the first reporting condition. The base station detects a mobile station that has transmitted a measurement report as a result of satisfaction of the second reporting condition as a handover required of mobile station whose radio quality becomes lower than a predetermined value within a predetermined period and performs a handover process of the mobile station.

    Abstract: A reference signal of a user equipment to which a resource (LB#1) is allocated for a L1/L2 control signal, is allocateda resource (SB#1) that is closer on the time axis to the resource (LB#1), which the L1/L2 control signal is allocated, within the same frequency band as the L1/L2 control signal. A reference signal for CQI estimation, independent of a data signal and a L1/L2 control signal, is allocated a resource with which at least one of a reference signal for demodulation of a data signal and a reference signal for demodulation of a L1/L2 control signal is not transmitted at the same timing within the transmission band. The types of bandwidths of the reference signals multiplexed in a same short block within a same band are reduced, whereby restrictions as to the number of reference signal sequences that can be secured are diminished.

    Abstract translation: 为L1 / L2控制信号分配资源（LB＃1）的用户设备的参考信号被分配为在资源（LB＃1）的时间轴上更靠近的资源（SB＃1） 其L1 / L2控制信号被分配在与L1 / L2控制信号相同的频带内。 分配与数据信号和L1 / L2控制信号无关的用于CQI估计的参考信号，用于解调数据信号的参考信号和解调L1 / L2的参考信号中的至少一个 在发送频带内的相同定时不发送控制信号。 减少在相同频带内的相同短块中多路复用的参考信号的带宽类型，从而减少了可以确保的参考信号序列的数量的限制。

    Abstract: An object of the present disclosure is to provide a data collection method being capable of suppressing a data amount of data being transmitted to a server device that performs monitoring. The data collection method according to the present disclosure includes collecting a packet being transmitted in a wireless system, generating a plurality of pieces of monitoring data being determined based on the packet, deciding whether first monitoring data included in a plurality of pieces of the monitoring data satisfy a predetermined reference, transmitting the first monitoring data to a cloud server (700) via a network when the first monitoring data do not satisfy the reference, and transmitting second monitoring data included in a plurality of pieces of the monitoring data together with the first monitoring data to the cloud server (700) via a core network (500) when the monitoring data satisfy the reference.
