Abstract: In order to provide low-load, efficient coding technology, a moving-picture decoding device includes a spatial motion information candidate derivation unit configured to derive a spatial motion information candidate from motion information of a block neighboring a decoding target block in a space domain and a history-based motion information candidate derivation unit configured to derive a history-based motion information candidate from a memory where motion information of a decoded block is retained, wherein the history-based motion information candidate derivation unit preferentially derives old motion information without making a comparison of the motion information with the spatial motion information candidate.

Abstract: Disclosed is an information transmission method. The method includes that: a first communication node determines a resource or parameter for a second communication node to transmit a reference signal, and indicates the resource or parameter to the second communication node through signaling; and the second communication node receives the signaling transmitted by the first communication node, determines the resource or parameter for transmitting the reference signal based on the signaling or based on the signaling and a rule predefined by the first communication node and the second communication node, and uses the determined resource or parameter to transmit the reference signal.

Abstract: It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.

Abstract: Provided is a radio communication base station device which can suppress a use amount of an SRS communication resource. In this device, a correlation rule setting unit (102) sets a rule for correlating a preamble with an SRS transmission time interval so that the preamble transmission time band and the SRS transmission time band are in the same transmission time band. An SRS transmission band decision unit (103) decides a time interval of a transmission time band which can transmit the SRS according to the preamble transmission time interval inputted from a preamble transmission band decision unit (101) and the correlation rule setting unit (102).

Abstract: A communication apparatus has a receiver and a transmitter. The receiver, in operation receives a control signal including a Modulation and Coding Scheme (MCS) Index, a channel quality indicator (CQI) trigger and information indicating uplink resource blocks. The transmitter in operation, determines whether to multiplex an aperiodic CQI report with data in an uplink signal based on the MCS Index, the channel quality indicator trigger, the information indicating uplink resource blocks, and a threshold number of resource blocks, and transmits the uplink signal.

Abstract: In a picture coding method for generating a coded signal corresponding to each picture by coding a plurality of coded signals, a switching picture which is capable of switching a plurality of coded signals and subsequent pictures of the switching picture can refer to only a group of pictures of the same time in the coded signals. More specifically, the case where picture numbers of an adjacent picture of an S picture and the S picture are not continuous is not considered as an error.

Abstract: A mobile terminal includes circuitry, a transmitter and a receiver. The circuitry, in operation, generates a CQI for each subcarrier (SC) group of multiple subcarrier groups, a plurality of subcarriers consecutive in a frequency domain being grouped into the multiple subcarrier groups. The transmitter, in operation, reports first respective CQIs of the multiple SC groups in inconsecutive time resources based on a first period, and reports, based on a second period, second respective CQIs of the multiple SC groups in inconsecutive time resources based on the first period, the second period being longer than the first period. The receiver, in operation, receives information indicative of the first period.
