The described technology is generally directed towards a composite HARQ-ACK response that contains information corresponding to a current HARQ-ACK composed with one or more previous HARQ-ACKs in a single uplink transmission. As a result, even with a HARQ-ACK repetition factor greater than one, the network is able to schedule the user equipment in consecutive time intervals as if the repetition factor was one (that is, as if no repetition).

A method of a user equipment (UE) for transmitting acknowledgement information. The method comprises receiving a physical downlink control channel conveying a downlink control information (DCI) format, a physical downlink shared channel conveying one or more data transport blocks scheduled by the DCI format, and configuration information for transmission of a physical uplink control channel (PUCCH) conveying acknowledgement information in response to the reception of the one or more data transport blocks; and transmitting the PUCCH in time-frequency resources within a first slot. An index of the first slot is configured by the DCI format. The time-frequency resources within the first slot are configured by the DCI format through a configuration of an index of a first symbol, a number of consecutive slot symbols, and an index of a first frequency resource block.

The present disclosure provide a method and terminal for counting preamble retransmission in a random access procedure. The method includes: in a random access procedure, when detecting that no Random Access Response (RAR) is received or contention resolution fails, counting a number of times of retransmission of a preamble and/or a number of times of power ramping of transmission of the preamble according to a configured counter/counters.

Provided are a method and apparatus for transmitting information, and a storage medium and a terminal. The method includes: determining, on an uplink feedback resource unit within a first downlink resource range currently occupied during downlink transmission, whether first response information corresponding to the first downlink resource range is successfully transmitted to a base station, wherein the uplink feedback resource unit includes a resource unit for transmitting the first response information to the base station; when the first response information is transmitted unsuccessfully, determining a target feedback resource unit within at least one second downlink resource range subsequently occupied during the downlink transmission; and retransmitting, on the target feedback resource unit, the first response information to the base station.

Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. At the time of channel selection, a control unit selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station and PUCCH resources mapped to a CCE, and controls the transmission of the response signal. A response signal generating unit supports implicit signaling with respect to any given response signal, and at the same time as supporting LTE fallback from 2CC, uses a mapping method that, between bits, smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

To appropriately perform communication even in a case where a transmission timing/transmission period for retransmission control information is flexibly controlled (is variable), an aspect of a user terminal according to the present invention includes a transmitting section that transmits retransmission control information for DL transmission and a control section that controls transmission of the retransmission control information at certain timings reported from a base station. A time window is configured for the retransmission control information, the control section controls transmission of the retransmission control information, based on the certain timings and the time window configured for the retransmission control information, and at least one of the certain timings is included within a range of the time window.

Various examples and schemes pertaining to uplink (UL) transmission timing for non-terrestrial networking (NTN) are described. An apparatus receives, from a network, downlink control information (DCI) indicating an NTN offset for a scheduling delay. Accordingly, the apparatus performs one or more UL transmissions to a satellite with the scheduling delay which accounts for the NTN offset.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first transmission on a first beam of a set of beams in a first time period of a first transmission duration. The UE may identify a second beam of the set of beams in a second time period of the first transmission duration. The UE may transmit an indication of the identified second beam of the set of beams for an uplink transmission and/or a downlink transmission in a second transmission duration. Numerous other aspects are provided.

To greatly improve transmission efficiency of an entire system by improving reliability while ensuring low delay with respect to notification of response information in a communication system in which a base station device and a terminal device communicate with each other. A terminal device that communicates with a base station device, the terminal device including: a reception unit that receives a data channel including one or more pieces of data; and a transmission unit that transmits response information to the data on the basis of a parameter regarding reliability of the data.

A method of generating Acknowledgement/Negative Acknowledgement (ACK/NACK) information by a user equipment (UE) in a wireless communication system is discussed. The method includes receiving, by the UE from a base station (BS), a plurality of codewords through a plurality of downlink frequency bands related to a plurality of downlink carriers, wherein the UE is configured with a 1-codeword mode or a 2-codeword mode for each of the plurality of downlink frequency bands independently, and wherein a number of supported codewords is one for the 1-codeword mode or two for the 2-codeword mode; determining, by the UE, a total number of ACK/NACK bits, wherein the total number of ACK/NACK bits is determined based on a total number of the plurality of downlink carriers and the number of supported codewords; and generating, by the UE, a sequence of the ACK/NACK bits based on the total number of the ACK/NACK bits.
