An SIR information extracting section 106 extracts SIR measured at a communication terminal from the received data, and a fluctuation amount calculating section 109 calculates a fluctuation amount of SIR between time at which the communication terminal has measured SIR and transmission starting time of DSCH data using a TPC command, and a transmission system determining section 110 adds the SIR fluctuation amount calculated in the fluctuation amount calculating section 109 to the SIR measured at the communication terminal and estimates SIR of DSCH data so as to determine an optimal transmission system of DSCH data according to the estimated SIR.

The invention relates to methods for reporting on downlink timings by a mobile terminal in a mobile communication system. In order to allow for an aggregation access point to obtain information on propagation delay differences of downlink transmissions on aggregated serving cells, the invention suggests the mobile terminal to report timing information based on reception time difference information for a the target/reference cell. The mobile terminal performs measurements relating to transmission and/or reception time differences on the target/reference cell, and reports same to the eNodeB. The eNodeB compares the measurement result to a predefined maximum propagation delay time difference. Alternatively, the mobile terminal performs the measurements, compares same to the predefined maximum propagation delay time difference and then report the comparison result to the eNodeB.

The invention relates to methods for adjusting the transmit power utilized by a mobile terminal for uplink transmissions, and to methods for adjusting the transmit power used by a mobile terminal for one or more RACH procedures. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for adjusting the transmit power of uplink transmissions on uplink component carriers, the invention suggests introducing a power scaling for uplink PRACH transmissions performing RACH procedures on an uplink component carrier. The power scaling is proposed on the basis of a prioritization among multiple uplink transmissions or on the basis of the uplink component carriers on which RACH procedures are performed.
摘要:
Disclosed is a technique to enable a communication node to acquire predetermined newer information (e.g., configuration information) held by another communication node while minimizing power consumption by communication nodes. According to the technique, when receiving a request for configuration information from a new MTC device 100, a MME 220 checks whether an existing MTC device 110 as a request target for configuration information connects or not. When the existing MTC device does not connect, the new MTC device is notified of time information (e.g., next connection time of the existing MTC device, a next connection time of a new MTC device or a next connection time zone of the new MTC device). This time information enables the new MTC device to specify a time after the MME acquires and holds the configuration information from the existing MTC device. The new MTC device reconnects based on this time information, whereby the new MTC device can acquire desired configuration information from the MME.

摘要:
Disclosed is a technique of efficiently collecting communication quality information with excellent responsiveness in wireless resource management. According to the technique, a RRM 110 distributes measurement content information showing measurement contents for recognizing a wireless communication status to each AP 230, and each AP stores the measurement content information. For example, to recognize a wireless resource use status of an AP, the RRM transmits trigger transmission instruction information to an eNB 150, as a result of which trigger information is transmitted throughout a communication area of the eNB. A UE 301 that has received the trigger information acquires the measurement content information from an AP (for example, AP_a 230a) to which it is connected, and performs a measurement process and reports a measurement result to the RRM via the eNB based on the measurement content information.
