The present disclosure provides communication apparatuses and communication methods for utilization of SL-RSRP in V2X resource sensing and selection. The communication apparatuses include a communication apparatus comprising: circuitry which, in operation, adjusts a parameter based on at least one of a plurality of priority levels, and determines a plurality of resource candidates based on the adjusted parameter; and a transmitter which, in operation, transmits a transmission block (TB) using a resource selected from the plurality of resource candidates.

Communication apparatuses and communication methods for utilization of SL-RSRP in V2X resource sensing and selection

A user equipment, a base station and respective methods are provided. The user equipment receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling, the PUSCH config IE being applicable to a particular bandwidth part. The user equipment configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, at least one row comprising a first set of values related to allocated time-domain resources for a plurality of PUSCH transmissions. The user equipment receives downlink control information (DCI) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The user equipment determines allocated time-domain resources for the plurality of PUSCH transmissions based on the index of the slot carrying the received DCI.

User equipment and system performing transmission and reception operations

The present invention improves the reliability of a transmission channel. A transmission terminal according to the present invention is equipped with: a control circuit that, on the basis of a time resource quantity used to determine the transmission size of a first channel in one time segment of either a first time segment in which the first channel and a second channel are disposed or a second time segment in which the first channel is disposed, determines the transmission size in the other time segment; and a transmission circuit that, on the basis of the determined transmission size, performs a transmission process for the first channel in the first time segment and the second time segment.

Transmission device, reception device, transmission method, and reception method

A terminal apparatus includes a receiver and a transmitter. The receiver receives, from a base station, a downlink assignment index (DAI) that is transmitted by means of a downlink control information (DCI) format. The DAI indicates an accumulative number of a transmitted physical downlink shared channel (PDSCH) included in a group of PDSCHs. A range of the accumulative number of which the DAI is indicative is variably configured. The transmitter, in operation, transmits, to the base station, hybrid automatic repeat request acknowledgement (HARQ-ACK) information based on the DAI.

Terminal apparatus to transmit hybrid automatic repeat request information and related communication method

A base station capable of appropriately transmitting a reference signal in an unlicensed band and a reception quality report measured using said reference signal. A control unit () of a base station () changes: the reference signal transmission timing which was set before carrier sensing on the basis of a time resource set according to carrier sensing results; and/or the report timing of the quality information measured in a terminalusing the reference signal. A transmission unit () and a receiving unit () communicate the reference signal or quality information on the basis of the changed timing.

Base station, terminal and communication method

A signal processing device includes: a transmission path estimator that estimates a first transmission path characteristic of a transmission signal using a vertical signal out of vertical and horizontal signals resulting from being received by a vertical polarization antenna and a horizontal polarization antenna; a transmission path estimator that estimates a second transmission path characteristic of the transmission signal using the horizontal signal; a weight calculator that calculates a first weight for the vertical signal and a second weight for the horizontal signal, using the first transmission path characteristic and the second transmission path characteristic; and a weighting applier that applies weighted summation to the vertical signal and the horizontal signal using the first weight and the second weight.
