A method and apparatus for supporting multi transport block grant (MTBG) data transmission in a wireless communication system, such as an LTE system. The method includes increasing the number of hybrid automatic repeat request (HARQ) processes in a HARQ cycle to greater than 8, where the HARQ processes are divided into two or more HARQ process groups. The method further includes specifying a delay indicative of time between the MTBG and commence of the data transmission and another delay indicative of time between the data transmission and acknowledgement (ACK).

Disclosed is the radio (wireless) communication system providing a radio communication service and the terminal, and more particularly, to a method of an uplink HARQ (Hybrid Automatic Repeat reQuest) operation at an expiry of time alignment timer in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from the Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.

Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

Timing considerations for autonomous uplink (AUL) downlink feedback information (AUL-DFI) is disclosed. With the flexible timeline for new radio (NR) operations, signaling of the processing timeline may be used for the served user equipments (UEs) to properly interpret the acknowledgement information in the AUL-DFI. The UE receives a signal identifying a minimum processing time of the serving base station to process AUL. Using the knowledge of the minimum processing time, the UE determines which of the outstanding AUL transmissions are accurately addressed in the AUL-DFI and which are still pending. Additional signaling to the UE may instruct the UE when to implement any changes to transmission parameters also signaled via the AUL-DFI. Slots prior to the indicated change time will be transmitted using the current parameters, while slots after the indicated time will use the updated parameters from the AUL-DFI.

Apparatuses, systems, and methods for a wireless device to disable a HARQ feedback in either a semi-static way or in a dynamic way and to perform HARQ optimization. The wireless device may be configured to receive a first set and a second set of HARQ process numbers, where the first set and the second set of HARQ process numbers correspond to a first set and a second set of HARQ processes respectively, where each HARQ process in the first set of HARQ processes is configured to enable a HARQ feedback, and where each HARQ process in the second set of HARQ processes is configured to disable or enable a HARQ feedback. The wireless device may be configured to receive a grant configuration or a SPS, where the grant configuration or the SPS include a flag indicating whether a HARQ-based retransmission is disabled.

A wireless device receives a downlink control information (DCI) comprising a first field indicating a transition of a cell to a dormant state and a second field indicating a hybrid automatic repeat request (HARQ) feedback timing. The wireless device transmits, in response to the DCI indicating the transition and via a physical uplink control channel resource, a positive acknowledgement of a reception of the DCI at a time interval based on the HARQ feedback timing.

Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.

Provided are an eNodeB (eNB) and a user equipment (UE) in a wireless communication system supporting a machine type communication (MTC). The present invention comprises: receiving a first message including a UE-specific configuration on the basis of a common configuration for a plurality of UEs; and receiving a second message according to the UE-specific configuration, wherein the common configuration may include at least one of the number of times of repetition of the first message and a rate matching pattern of the first message.
