    Abstract: A METHOD AND A SYSTEM OF SETTING UP A REFERENCE SIGNAL IN A RADIO COMMUNICATION SYSTEM. THE RADIO COMMUNICATION SYSTEM INCLUDES A SERVING CELL AND A NEIGHBORING CELL, AND A MOBILE TERMINAL OF THE SERVING CELL USES THE SAME TEMPORAL FREQUENCY RESOURCE SO AS TO RECEIVE A SERVING RESOURCE BLOCK FROM THE SERVING CELL AND RECEIVE AN INTERFERENCE RESOURCE BLOCK FROM THE NEIGHBORING CELL. THE METHOD ACCORDING TO THE PRESENT DISCLOSURE INCLUDES A STEP OF SETTING UP A USER-SPECIFIC REFERENCE SIGNAL IN THE INTERFERENCE RESOURCE BLOCK AND A STEP IN WHICH PUNCTURING IS PERFORMED AT SAME TEMPORAL FREQUENCY POSITION AS THE TEMPORAL FREQUENCY POSITION AT WHICH THE USER-SPECIFIC REFERENCE SIGNAL IS SET UP ON THE INTERFERENCE RESOURCE BLOCK OF THE SERVING RESOURCE BLOCK SO AS TO PREVENT ANY SIGNAL FROM BEING TRANSMITTED AT THE PUNCTURED TEMPORAL FREQUENCY POSITION. WHEN THE METHOD AND THE SYSTEM PROVIDED IN THE PRESENT DISCLOSURE ARE USED AND THE INTERFERENCE POWER BETWEEN CELLS IS THEREBY MEASURED, IT IS POSSIBLE TO EFFECTIVELY REDUCE FEEDBACK OVERHEAD IN A COORDINATED BEAMFORMING.

    Abstract: A method for determining Channel Quality Indicators to be reported by User Equipments in base station cooperation, and a base station and a User Equipment therefor are provided. The method comprising: assigning a sequence of adjustment factors to various possible base station cooperations; transmitting the assigned adjustment factors to UEs; calculating an original CQI for each possible base station cooperation in each UE; adjusting the original CQIs based on the received adjustment factors in UEs; and reporting one or multiple original CQI(s) that are the highest after the aforesaid adjustment and knowledge of which CQI(s) are reported to the base station by each UE.

    Abstract: Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal (200), a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS), whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an "SRS Transmission Execution Rule" and the reception status of trigger information.

    Abstract translation: 提供一种通信装置和SRS传输方法，其能够降低基站与终端之间或SRS资源之间SRS传输的存在或不存在之间的识别差异的可能性，从而防止系统吞吐量的降低。 在终端（200）中，接收处理部（203）检测表示是否请求发送探测参考信号（SRS）的控制信息，发送信号形成部（207）通过发送A-SRS 由传输控制单元（206）基于控制信息进行控制。 传输控制单元（206）基于“SRS传输执行规则”和触发信息的接收状态来确定是否执行SRS传输。

    Abstract: Provided are a wireless communication terminal apparatus, a radio communication base station apparatus and a wireless communication method whereby the increase in the number of signaling bits can be suppressed, while the SRS capacity can be improved. RS type determining unit (105) determines, based on scheduling information, that the signal is an SRS signal accompanied by no data or a DMRS signal accompanied by data. CS amount deciding unit (106) holds a CS amount for DMRS and a CS amount for SRS that are defined such that the CS amount for SRS includes a CS amount not included in the CS amount for DMRS. The CS amount deciding unit (106) uses CS amount notification information, which is included in the scheduling information, and the CS amount definition to derive a CS amount in accordance with the RS type outputted from the RS type determining unit (105).
