The node information includes: a Node Type, which indicates whether or not the source node is mobile: an M-RN Group ID, which, when the source node is a mobile RN, indicates, the M-RN group to which the RN belongs; and a Movement Condition, which indicates the mobility status of the source node. | 09-18-2014 |
20140293822 | COMMUNICATION CONTROL METHOD, BASE STATION, AND USER TERMINAL - A communication control method including a first base station and a second base station having a smaller coverage area than the first base station, comprises: a step A, performed by the second base station, of notifying the first base station of a reference signal transmission power of the second base station; a step B, performed by a user terminal connected to the first base station, of measuring a reference signal received power from the second base station, and then reporting the reference signal received power to the first base station; and a step C, performed by the first base station, of estimating a path loss between the second base station and the user terminal, on the basis of the reference signal transmission power notified from the second base station in the step A and the reference signal received power reported from the user terminal in the step B. | 10-02-2014 |
20140307542 | COMMUNICATION CONTROL METHOD AND RELAY STATION - An M-RN has a UE function unit for establishing an RRC connection with an eNB on a backhaul link, and an eNB function unit for establishing an RRC connection with a UE on an access link. In an RRC_CONNECTED state in which an RRC connection with an eNB has been established, the UE function unit detects disconnection of the backhaul link. After detecting the disconnection of the backhaul link and before transitioning to an RRC_IDLE state in which the RRC connection with the eNB is released, the UE function unit transitions to an RRC_SEMI-IDLE state in which it keeps the RRC connection with the eNB and tries a recover of the backhaul link. While the UE function unit is in the RRC_SEMI-IDLE state, the eNB function unit performs control in order to keep the RRC connection with the UE ( | 10-16-2014 |
20140307687 | COMMUNICATION CONTROL METHOD, MOBILE COMMUNICATION SYSTEM, AND BASE STATION - A communication control method in a mobile communication system having a first base station and a second base station having a smaller coverage area than the first base station, comprises: a step A of transmitting information indicating interference in uplink detected by the second base station, from the second base station to the first base station; a step B of performing processing by the first base station and/or the second base station to change a radio environment around the boundary of a coverage area of the second base station; and a step C of identifying an interfering user terminal in the uplink by the first base station, from first user terminals being connected with the first base station, based on radio environment information reported by the first user terminals. | 10-16-2014 |
20150023320 | COMMUNICATION CONTROL METHOD, BASE STATION, HOME BASE STATION, AND GATEWAY DEVICE - A communication control method includes: an establishment step of establishing, between a home base station selected from a plurality of home base stations in control of a gateway device and other base station not in control of the gateway device, a communication path which passes through the gateway device and which does not pass through a core network; and a step of performing inter-base station communications using the communication path established in the establishment step, by the selected home base station and the other base station. | 01-22-2015 |
