A terminal includes: a control unit configured to control predetermined communication, which uses a same antenna port, for transmitting two or more transport blocks by using frequency division multiplexing; and a reception unit configured to receive downlink control information used for the predetermined communication, wherein the control unit controls the predetermined communication based on the downlink control information.

A wireless device receives a DCI indicating a first priority of a transport block and a hybrid automatic repeat request (HARQ) feedback timing of a HARQ feedback of the transport block. The wireless device switches, after receiving the DCI and before the HARQ feedback timing, from a first bandwidth part to a second bandwidth part as an active bandwidth part. The wireless device transmits or drops the HARQ feedback based on whether or not the first priority of the transport block comprises a first value.

A method performed by a UE for implementing a random access procedure is provided. The method transmits a MSGA, monitoring an MSGB-RNTI within an MSGB time window starting from an earliest symbol of an earliest PDCCH occasion after the MSGA transmission. The method receives the MSGB in a first slot. The MSGB includes a success RAR that contains a HARQ Feedback Timing Indicator, a Physical Uplink Control Channel (PUCCH) Resource Indicator, and a UE Contention Resolution Identity. The method determines, by a MAC entity of the UE, to instruct a lower layer to transmit a HARQ feedback in a second slot in response to the reception of the success RAR. The method delivers, by the MAC entity, the HARQ Feedback Timing Indicator and the PUCCH Resource Indicator to the lower layer, and performs, by the lower layer, a HARQ feedback delivery on an uplink (UL) resource.

The at least one processor may be configured to: control the at least one transceiver to transmit first data based on a first hybrid automatic request (HARQ) process; control the at least one transceiver to transmit second data based on the first HARQ process; based on transmitting the second data, generate third databased on the result of the first data being received; and control the at least one transceiver to transmit the third data based on a second HARQ process.

The present disclosure provides a terminal device that allows constraints on user allocation to be prevented and spread codes to be allocated in a scheduler when non-adaptive HARQ is employed using a PHICH. A codeword generator generates code words by encoding data, a layer mapping unit places each CW in one or a plurality of layers, a DMRS generator generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs, and an ACK/NACK demodulator receives a response signal indicating a retransmission request. When a response signal requesting retransmission of only a CW placed in a plurality of layers is received, the DMRS generator uses each resource having the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.

The present disclosure provides a method of receiving system information by a user equipment in a wireless communication system. Particularly, the method may include receiving a Physical Downlink Control Channel (PDCCH) including Downlink Control Information (DCI) for scheduling the system information; descrambling a Cyclic Redundancy Check (CRC) of the DCI based on a System Information-Radio Network Temporary Identifier (SI-RNTI); obtaining first information on a type of the system information from a specific bit included in the DCI; receiving the system information based on second information for scheduling the system information, which is included in the DCI; and determining the type of the system information based on the first information.
