摘要： To make a mobile station apparatus efficiently generate a base sequence. In a mobile station apparatus that generates a sequence for a demodulation reference signal on the basis of at least a sequence group number and transmits to a base station apparatus the demodulation reference signal together with a physical uplink shared channel used for transmission of a transport block, the mobile station apparatus receives information indicating a value of a parameter relating to the sequence from the base station apparatus, and determines the sequence group number without using the value of the parameter in a case where the mobile station apparatus performs transmission of the transport block on the physical uplink shared channel as part of a contention based random access procedure.

摘要： A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

摘要： There are provided a terminal device, a base station device, and an integrated circuit that enable a base station device and a terminal device to determine parameters related to uplink signals or uplink reference signals and to perform efficient communication. A terminal device that transmits a demodulation reference signal associated with a physical uplink shared channel to a base station device includes determining a sequence group number on the basis of a value of a parameter configured by a higher layer, determining the sequence group number on the basis of a physical layer cell identity, and generating a sequence of the demodulation reference signal on the basis of the sequence group number, wherein the sequence group number is determined on the basis of the physical layer cell identity in a case where a transmission on the physical uplink shared channel corresponding to a downlink control information format to which CRC parity bits scrambled by a Temporary C-RNTI are attached is performed in a random access procedure.

摘要： A terminal apparatus includes: a receiver configured to detect a DCI format in a search space; a coding unit configured to divide a transport block into one or multiple code blocks, based at least on the DCI format and code the one or multiple code blocks to generate coded bits; and a transmitter configured to transmit the coded bits on a PUSCH. Multiplexed bits are given based at least on concatenation of the coded bits generated by coding the one or multiple code blocks. The coding unit maps the multiplexed bits to a matrix in a first-axis prioritized manner and reads out the multiplexed bits mapped to the matrix in the first-axis prioritized manner or a second-axis prioritized manner. Whether to prioritize the first axis or the second axis in a case of reading out the multiplexed bits mapped to the matrix, is based at least on whether or not the search space is CSS.

摘要： A cell using an unallocated frequency band or a shared frequency band is efficiently controlled. A terminal device includes a reception unit configured to receive a first downlink physical channel mapped on the basis of a first possible starting position of a downlink transmission and a second downlink physical channel mapped on the basis of a second possible starting position of the downlink transmission. Upon the first possible starting position and the second possible starting position being indicated by a higher layer, the reception unit receives, in a predetermined subframe, either one of the first downlink physical channel or the second downlink physical channel, on a secondary cell having a frame structure type 3.

摘要： There is provided a terminal for performing OFDM (Orthogonal Frequency-Division Multiplexing) communication with a base station forming a cell. The terminal includes a control channel processing unit configured to monitor, in a sub-frame, a first control channel in a cell-specific search space that is a search space common within the cell, and a first control channel in a UE-specific search space that is a search space specific to the terminal. In a case where monitoring of a second control channel different from the first control channel that is in the cell-specific search space or the UE-specific search space is configured, the control channel processing unit monitors, in a sub-frame, at least both the first control channel in the cell-specific search space and the second control channel in the UE-specific search space.

摘要： There is provided a terminal device which includes a transmission unit that transmits HARQ response information to a first serving cell and a second serving cell on a physical uplink shared channel in a subframe n. The physical uplink shared channel is transmitted based on a physical downlink control channel or an enhanced physical downlink control channel which is detected in a state of including a downlink control information format 0/4. Two or more serving cells are configured in the terminal device, in a case where frame constitution types of any two configured serving cells are different from each other, and in a case where a primary cell has Frame constitution type 2, BcDL is applied to the first serving cell of Frame constitution type 2 by using the following expression (1), and is applied to the second serving cell of Frame constitution type 1 by using the following expression (2).[Math. 1] BcDL=min(WDAIUL,Mc) Expression (1) [Math. 2] BcDL=min(WDAIUL+4┌(U−WDAIUL)/4┐,Mc) Expression (2)

摘要： There is provided a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other. The terminal device that communicates with the base station device by using a plurality of aggregated cells recognizes that a serving cell is stopped in a first state, recognizes that the serving cell is started in a second state, and switches from the first state to the second state based on a received PDCCH.

摘要： A terminal device and a base station device efficiently communicate with each other. For the terminal device, in a case that third information is configured, a third maximum number of the layers assumed for determining a bit width for a first RI and a fourth maximum number of the layers assumed for determining a bit width for a second RI are provided, based on the third information. In case that the third information is not configured, the third maximum number and the fourth maximum number are provided, based on a smallest one of a first number and a second number. The first number is a second maximum number of the layers indicated by second information, and the second number is a largest one of the number of antenna ports of a first CSI-RS resource and the number of antenna ports of a second CSI-RS resource.
