20130093459 | TERMINATION DEVICE SYSTEM - A termination device system is provided that includes a device required to be terminated with a resistor and a termination circuit. The termination circuit includes a termination resistor circuit and a judgment circuit connected to the termination resistor circuit. The termination resistor circuit includes at least one controlled termination unit. Each controlled termination unit includes a termination connecting end for connecting the device required to be terminated with a resistor, a controlled switch and a resistor, and provides, based on on/off of the controlled switch, a termination resistor for the device connected to the termination connecting end. The judgment circuit judges whether the device is required to be connected to the termination resistor based on a control instruction of a control device controlling the device connected to the termination connecting end, to output an on/off control signal to the controlled switch of the termination resistor circuit to control on/off. | 04-18-2013 |
20130124816 | DEVICE REQUIRING ADDRESS ALLOCATION, DEVICE SYSTEM AND ADDRESS ALLOCATION METHOD - A device requiring address allocation, a device system, and an address allocation method. A control device in the device system transmits currently allocated address information and a contention start signal to each device requiring address allocation in the device system through a bus, and the devices requiring address allocation with address allocation flag information being that no address information is allocated output an address contention signal. When outputting the address contention signal, each device requiring address allocation determines whether the currently allocated address information is available according to whether the other devices requiring address allocation with address allocation flag information being that no address information is allocated already output address contention signals. When determining availability of currently allocated address information, the device requiring address allocation stores currently allocated address information, and modifies address allocation flag information to address information already allocated, thereby achieving address allocation for the devices. | 05-16-2013 |
20130166870 | VOLTAGE AND TIMING CALIBRATION METHOD USED IN MEMORY SYSTEM - A voltage and timing calibration method used in a memory system. A memory controller adjusts timing and voltages of the controller and voltages of a memory buffer according to data returned by the buffer based on timing and voltages at a memory controller side of the buffer, to calibrate timing and voltages between the controller and controller side. According to data read by the buffer from a memory chip unit on the basis of timing and voltages at a memory chip side of the buffer, the controller adjusts the timing and voltage at the chip side and the voltage of the chip unit; or the buffer adjusts the timing and voltage at the chip side and the voltage of the chip unit, to calibrate the timing and voltage between the chip side and chip unit. Therefore, hardware resources of the buffer can be saved and the circuit can be simplified. | 06-27-2013 |

20150358098 | RADIO BASE STATION, USER TERMINAL AND RADIO COMMUNICATION METHOD - The present invention is designed to reduce the impact of interference even when different DL/UL configurations are applied between neighboring transmission points (radio base stations). A radio base station which can communicate with a user terminal by means of time division duplexing, and furthermore change and control the DL/UL configuration, has an interference measurement section that measures the interference level from other radio base stations in at least a UL subframe, and a scheduling control section that changes the feedback method of uplink control signals, which the user terminal feeds back in the UL subframe in response to downlink signals that have been transmitted in DL subframes, based on the measured interference level. | 12-10-2015 |
20160072617 | RADIO BASE STATION, USER TERMINAL AND RADIO COMMUNICATION METHOD - In order to provide feedback information of a transmission acknowledgement signal or the like appropriately even in change in DL/UL configuration in TDD, the present invention provides a radio base station that communicates with a user terminal by time division duplex and is capable of controlling change in DL/UL configuration. The radio base station includes: a determining section that determines feedback timing of a transmission acknowledgement signal of a DL subframe in a radio frame before change in DL/UL configuration; and a control section that controls a UL subframe to use in feedback of the transmission acknowledgement signal of the DL subframe, based on the feedback timing. When the transmission acknowledgement signal is to be fed back in a radio frame after change in DL/UL configuration, the control section reconfigures the UL subframe to use in feedback based on a feedback range covered by a UL subframe after change in DL/UL configuration. | 03-10-2016 |
20160099801 | USER TERMINAL, RADIO BASE STATION AND RADIO COMMUNICATION METHOD - The present invention is designed to feed back feedback signals such as delivery acknowledgement signals properly even when the DL/UL configuration is reconfigured in TDD. A user terminal communicates, in time division duplexing, with a radio base station that reconfigures the DL/UL configuration, and has a judging section that judges a delivery acknowledgement in response to each DL subframe, and a feedback control section that allocates a delivery acknowledgement signal in response to each DL subframe to a UL subframe and sends feedback, and, when the number of DL subframes that correspond to a UL subframe is greater than a predetermined value in a radio frame after the reconfiguration of the DL/UL configuration, the feedback control section bundles at least part of the delivery acknowledgement signals for a plurality of DL subframes corresponding to the UL subframe, and sends feedback. | 04-07-2016 |
