    Abstract: A user terminal, user terminal chipset, and method including receiving, from a cellular base station included in a cellular radio access network (RAN), parameters for an offload from the cellular RAN to a wireless local area network (LAN), and performs an access network selection between the cellular RAN and the wireless LAN based on the parameters. Parameters include a first threshold to be compared with a cellular signal strength of the cellular RAN, a second threshold to be compared with a wireless LAN signal strength of the wireless LAN, and a third threshold to be compared with a load of the wireless LAN. Performing the access network selection includes selecting the wireless LAN to perform the offload, in response to the cellular signal strength being lower than the first threshold, the wireless LAN signal strength being higher than the second threshold, and the load being lower than the third threshold.

    Abstract: A radio base station according to an embodiment is a radio base station configured to use a specific frequency band which includes a plurality of component carriers having a predetermined bandwidth and which is allowed to be utilized by a plurality of network operators or a plurality of communication systems. The radio base station comprises: a controller configured to select, from among the plurality of component carriers, a target component carrier in which a reference signal used in the specific frequency band should be transmitted; and a transmitter configured to use the target component carrier to transmit the reference signal. The controller selects, as the target component carrier, a first component carrier that satisfies a first condition. The first condition is that an interference power amount falls below a predetermined threshold value.

    Abstract: A user terminal according to one aspect executes a first and second DRX operations. The first DRX operation is an operation of discontinuously monitoring first control information, which is transmitted from the base station via PDCCH, using a C-RNTI that uniquely identifies the user terminal in a cell of the base station. The second DRX operation is an operation of discontinuously monitoring second control information, which is transmitted from the base station via the PDCCH, using a group RNTI assigned to a terminal group including the user terminal. The user terminal monitors the first control information in a first ON duration for the first DRX operation, and monitors the second control information in a second ON duration for the second DRX operation, the second ON duration being independent of the first ON duration.

    Abstract translation: 根据一个方面的用户终端执行第一和第二DRX操作。 第一DRX操作是使用唯一地识别基站的小区中的用户终端的C-RNTI来不连续地监视从基站经由PDCCH发送的第一控制信息的操作。 第二DRX操作是使用分配给包括用户终端的终端组的组RNTI来不连续地监视从基站经由PDCCH发送的第二控制信息的操作。 用户终端在第一DRX操作的第一ON持续时间内监视第一控制信息，并且在第二DRX操作的第二ON持续时间中监视第二控制信息，第二ON持续时间独立于第一ON持续时间。
