  • Patent number: 10455390
    Abstract: A repeater generates repetition signals by repeating an uplink signal over a plurality of subframes. If the plurality of subframes do not include a transmission candidate subframe of a sounding reference signal used to measure uplink reception quality, a controller sets a first transmission format to all the plurality of subframes, and if the plurality of subframes include the transmission candidate subframe, the controller sets a second transmission format to all the plurality of subframes. A transmitter transmits the repetition signals using the set transmission format.

  • Patent number: 10455523
    Abstract: The present invention prevents an increased error rate, degradation of reception-quality estimation precision, and complication of control in an operation for independently controlling, for individual component carriers (CC), transmission timing of an uplink subframe. When a radio communication terminal device independently controls the subframe transmission timing for individual CCs, and a portion of the total transmission power where overlap exists between the trailing-end portion of a subframe of a CC and a leading-end portion of a subframe of another CC exceeds a tolerance, the terminal device controls the timing such that the transmission power of a symbol including the overlapping portion is reduced.

  • Publication number: 20190320438
    Abstract: The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.

    Abstract: A user equipment includes circuitry which selects a random access preamble sequence, and a transmitter which transmits the random access preamble sequence to a base station in a frequency bandwidth of an unlicensed band, and performs at least one of a first operation and a second operation. In the first operation, the circuitry selects a first sequence as the random access preamble sequence, the first sequence having a length longer than a length of a random preamble sequence used for a licensed band, and the transmitter transmits the first sequence in the frequency bandwidth of the unlicensed band. In the second operation, the circuitry selects a second sequence as the random access preamble sequence, the second sequence having a length equal to the length of a random preamble sequence used for the licensed band, and the transmitter transmits the second sequence with repetitions in the frequency bandwidth of the unlicensed band.

  • Patent number: 10433231
    Abstract: In a terminal that judges whether to trigger a handover from a serving cell to another cell, a RSRQ/RSRP measurer measures a first received quality value by using a cell-specific reference signal transmitted from the neighboring cell or a second received quality value by using a cell-detection reference signal transmitted from the neighboring cell. An offset adder calculates a third received quality value by adding an offset value to the second received quality value. A judging circuitry judges whether the first received quality value or the third received quality value satisfies a handover triggering condition with reference to the cell-specific reference signal. A transmitter transmits trigger information to the neighboring cell in order to activate handover from a serving cell to the neighboring cell, based on the judgement results.

  • Patent number: 10405352
    Abstract: In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit in base station sets a first resource candidate group, which enables terminal capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

  • Patent number: 10405297
    Abstract: The present disclosure relates to a method for paging coverage extension UEs in a cell controlled by a radio base station. At least one CE-specific paging possibility is defined for paging CE-UEs. The CE-UEs in the cell regularly monitor the at least one CE-specific paging possibility. When the radio base station determines to page all the user equipments in the cell, it pages the CE user equipments in the cell at the CE-specific paging possibility, using a coverage extension technique. The disclosure also relates to a method for paging a CE-UE, which performs radio measurements by a CE-capable user equipment to determine whether coverage extension is necessary. The radio base station is informed about whether the CE-capable user equipment needs coverage extension and then pages the CE-UEs applying or not applying a CE technique depending on whether coverage extension is necessary.

  • Publication number: 20190268121
    Abstract: The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localized, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.
