Definitions

  • the present invention is a wireless communication system including a base station device and a terminal device that performs wireless communication with the base station device, wherein the base station device A report acquisition unit that acquires a report on the measurement result of the terminal device from the terminal device, and a selection unit that selects a transmission state, and the transmission state includes one or more radios that are not subject to interference from other base station devices A first transmission state in which transmission is performed using a first radio resource subset configured to include resources, and one or more radio resources that may receive interference from other base station apparatuses At least a second transmission state in which transmission is performed using at least the second radio resource subset to be transmitted, and the report acquisition unit includes one or more of the second radio resource subsets.
  • the subset information acquisition unit acquires the subset information transmitted as broadcast information from the base station apparatus from the base station apparatus.
  • the terminal device can acquire the subset information even if the connection between the terminal device and the base station device is not established.
  • the present invention viewed from another viewpoint includes a measurement step in which the terminal device measures downlink communication quality, and a transmission step in which the terminal device transmits a report on the measurement result of the communication quality to the base station device,
  • a first radio resource subset configured to include one or a plurality of radio resources that are not subject to interference from other base station apparatuses.
  • a femto BS 1 c that is a HeNB is connected to the MME 3 via a HeNB gateway (GW) 5.
  • the MME 3 and the gateway 5 and the gateway 5 and the femto BS 1c are also connected by lines 6 using communication interfaces called S1 interfaces, respectively.
  • the femto BS 1c may be connected to the MME 3 through the S1 interface without going through the HeNB gateway (GW) 5.
  • the radio resource that is not used may be a frequency.
  • the pico BS 1b transmits interference to the terminal apparatus 2a located near the cell edge of the pico cell in a subframe subset including many subframes having timings corresponding to the ABS of the macro BS 1a, thereby preventing interference from the macro BS 1a.
  • the impact can be reduced.
  • the state selection unit 15 selects a transmission state based on the CQI report acquired by the CQI report acquisition unit.
  • the transmission state includes a first transmission state and a second transmission state.
  • the selection unit 15 selects one of the first transmission state and the second transmission state.
  • the pico BS 1b performs transmission in the selected transmission state.
  • the transmission state may include other transmission states other than the first transmission state and the second transmission state.
  • the terminal device 2 can acquire the subset information even before the connection establishment process is performed (when the terminal device is in an idle state).
  • the terminal device 2 of the present embodiment is located in the pico cell PC, but in the idle mode in which the connection with the pico BS 1b is not established, CQI is measured in advance. And the terminal device 2 transmits a CQI report with respect to pico BS1b, when changing to the connection establishment mode (Connected Mode) with pico BS1b from idle mode. Thereby, pico BS1b can select an appropriate transmission state at an early stage.
  • FIG. 32 shows a specific example of the second procedure when the CQI measurement result (CQI information) of the subset designated from the pico BS 1b attempting to establish a connection is not included.
  • the CQI measurement by the CQI measurement unit 22 of the terminal device 2 is performed after the connection (RRC Connection) establishment process (wireless connection control) (step S12-1).
  • the state selection unit 15 of the pico BS 1b selects the first transmission state or the second transmission state (step S12-2). Note that, in S12-2 of FIG. 32, the selection by the selection unit 15 is shown as the determination of whether or not the second subframe subset B can be used (whether or not the second transmission state can be used).

Abstract

La présente invention permet une communication appropriée avant même l'acquisition d'un rapport CQI. Un dispositif de station de base (1b) qui effectue une communication sans fil avec un dispositif terminal (2) est pourvu d'une unité d'acquisition de rapport pour acquérir un rapport CQI d'un dispositif terminal, et d'une unité de sélection pour sélectionner un état ​​de transmission. L'état de transmission comprend un premier état de transmission ​​où la transmission est effectuée en utilisant un premier sous-ensemble de ressources sans fil (A) configuré en incluant une ressource sans fil qui ne reçoit pas d'interférence d'un autre dispositif de station de base (1a), et un second état de transmission où la transmission est effectuée en utilisant au moins un second sous-ensemble de ressources sans fil (B) configuré en incluant une ressource sans fil qui est susceptible de recevoir une interférence d'un autre dispositif de station de base (1b). L'unité d'acquisition de rapport (14) acquiert un rapport CQI pour le second sous-ensemble de ressources sans fil auprès du dispositif terminal (2). L'unité de sélection (15) sélectionne l'un ou l'autre du premier état de transmission et du second état ​​de transmission sur la base du rapport CQI tout en sélectionnant le premier état de transmission jusqu'à ce que le rapport CQI soit acquis.
