Abstract: Provided are a radio communication terminal apparatus and a radio transmission method by which intersymbol interference of DM-RS of a CoMP terminal and a Non-CoMP terminal can be reduced. A CoMP set setting unit (102) sets the cell IDs of all cells in the CoMP set in a cell selection unit (104), and a serving cell setting unit (103) sets the cell ID of the serving cell in the cell selection unit (104). The cell selection unit (104) selects the cell ID having a number closest to the cell ID of the serving cell from the cells in the CoMP set. A sequence information calculation unit (106) derives a sequence group number from the selected cell ID, and the sequence information calculation unit (106) calculates a sequence number from the derived sequence group number and a transmission bandwidth of the DM-RS.

Abstract: A wireless communication base station device, terminal device, and method have reduced signaling while maintaining high scheduling gain. A judgment unit pre-stores a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality, and the maximum value for the number of clusters that is output by the judgment unit, a scheduling unit schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

Abstract: It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, w2} to be multiplied on the reference signal. A complex coefficient multiplication unit reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.

Abstract: Disclosed are a wireless communication base station device and a division number determination method that improve the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.

Abstract: Communication apparatuses and methods for providing radio resource selection and reporting for a sidelink (SL) communication are provided. The techniques disclosed here feature a method including determining, at a transmitting User Equipment (TX UE), a first set of candidate resources having a high priority from all resources for the SL communication. The, first set of candidate resources are determined based on at least a reference signal received power (RSRP) of the SL communication and a discontinuous reception (DRX) inactive time of a receiving UE (RX UE). The method also includes reporting a subset of all the resources to higher layers wherein the subset of all the resources meets a condition, and wherein the subset of all the resources includes ones of the first set of candidate resources that meet the condition.

Abstract: Apparatuses and systems for providing multiple structures to enable flexibility of a multiple transmission and reception point ultra-reliable low-latency communication (M-TRP URLLC) operation and reduce measurement effort and power consumption from a transceiving apparatus such as a UE are provided. The techniques disclosed here feature a transceiving apparatus including a transceiver and circuitry. The transceiver, in operation, receives signals from multiple transmission and reception points (M-TRPs) in a network on at least physical downlink shared channels (PDSCHs). The circuitry, in operation, performs beam failure recovery (BFR) by evaluating beam failure detection (BFD) and candidate new beam detection (CBD) for the signals from at least a first one of the M-TRPs. The signals from the first one of the M-TRPs comprise signals received on a physical downlink control channel (PDCCH), and the circuitry determines to skip evaluation of one or both of the BFD and the CBD for one or more additional ones of the M-TRPs in response to one or more conditions.

Abstract: This invention is a transmission device capable of enhancing the reception characteristics of a terminal when employing transmit diversity using two antenna ports in an ePDCCH. In a base station (100) that transmits a reference signal to a terminal (200) using two antenna ports, a setting unit (102), on the basis of the reception quality of the terminal, sets as the aforementioned two antenna ports either a first antenna port pair for which DMRS (reference signals) do not undergo mutual code multiplexing, or a second antenna port pair for which the DMRS do undergo code multiplexing. A transmitter (109) transmits the DMRS from the two antenna ports set in the setting unit (102).
