There is disclosed a method of operating a wireless device in a wireless communication network, the wireless device being triggered for aggregated transmission of first control information associated to a control channel, the aggregated transmission indicating a number R of retransmissions of the first control information to be performed. The method includes transmitting the first control information on a data channel based on a scaling parameter, the scaling parameter being based on the number R of retransmissions. The disclosure also pertains to related devices and methods.

A method for transmitting uplink control information and an apparatus therefor are disclosed. In a method for transmitting uplink control information using a physical uplink shared channel (PUSCH) in a wireless communication system, the method is performed by a terminal and includes receiving downlink control information including an accumulated number of physical downlink shared channels (PDSCH) transmissions associated with a cell group configured for the terminal, coding the uplink control information using the accumulated number of PDSCH transmissions, and transmitting the coded uplink control information using the PUSCH.

Methods and apparatuses for providing hybrid automatic repeat request acknowledgement (HARQ-ACK) information. A method includes receiving a first physical downlink control channel (PDCCH) that schedules a transmission of a physical uplink shared channel (PUSCH) in a slot and receiving PDCCHs that schedule receptions of first multicast physical downlink shared channels (PDSCHs), respectively. A first number of the PDCCHs is not received after the first PDCCH, and a second number of the PDCCHs is received after the first PDCCH. The method further includes determining that transmission of a PUCCH to provide the HARQ-ACK information associated with receptions of multicast PDSCHs, that include the first multicast PDSCHs, would overlap in time with the PUSCH transmission in the slot and transmitting the PUSCH. The PUSCH includes first HARQ-ACK information associated with the first number of PDCCHs and does not include second HARQ-ACK information associated with the second number of PDCCHs.

A method by which a terminal transmits uplink control information (UCI) in an unlicensed band and a device using the method are provided. The method generates data and first UCI including information necessary to decode the data, and transmits, to a base station, the data and the first UCI through a physical uplink shared channel (PUSCH) in an unlicensed band, wherein the first UCI further includes information necessary to decode the second UCI when second UCI is transmitted to the base station together with the data and the first UCI through the PUSCH.

An uplink transmission method performed by a terminal includes: receiving, from a base station, at least one DCI for allocating first uplink transmission and second uplink transmission; performing a first LBT procedure for the first uplink transmission, and performing the first uplink transmission when the first LBT procedure is successful; and performing a second LBT procedure for the second uplink transmission, and performing the second uplink transmission when the second LBT procedure is successful, wherein the first uplink transmission and the second uplink transmission are consecutively performed with a time interval longer than a predetermined time.

An uplink information transmission method and apparatus are disclosed. The uplink information transmission method includes: receiving, by a terminal device, downlink control information DCI sent by a network device, and determining, based on the DCI, a transmission resource of a physical uplink shared channel PUSCH scheduled by using the DCI, where the transmission resource of the PUSCH overlaps a transmission resource of a physical uplink control channel PUCCH in time domain, and the PUCCH is used to carry to-be-transmitted uplink control information UCI; and when a first condition is met, sending, by the terminal device, uplink data on the PUSCH, and skipping sending the UCI on the PUSCH.

This application discloses methods an apparatuses for sending and receiving uplink control information in the field of communications technology. In some implementations, a terminal device may receive first downlink control information (DCI) from a network device; determine, based on the received first DCI, that an uplink shared channel scheduled by using the first DCI is used to send only uplink control information (UCI); and send first UCI to the network device through the uplink shared channel scheduled by using the first DCI. In other words, the network device indicates to the terminal device by using DCI so that the terminal device can determine, based on an indication of the network device, whether the uplink shared channel scheduled by using the DCI is used to send only the UCI.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive scheduling information that schedules an uplink data message over a high priority physical uplink shared channel (PUSCH) that overlaps in time with a physical uplink control channel (PUCCH) resource over which the UE is scheduled to transmit feedback associated with sidelink communication. The UE may receive signaling from a base station indicating whether the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH. As such, the UE may multiplex the feedback associated with the sidelink communication on the high priority PUSCH if the signaling from the base station indicates that the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH.

Aspects relate to wireless communication including the provision of the ability of a user equipment (UE) to indicate the capability of the UE for demodulation reference signal (DMRS) bundling and/or joint channel estimation (JCE). In aspects, the capability indication includes using at least a physical random access channel (PRACH) to indicate the capability of a UE for repeated transmission of the physical uplink shared channel (PUSCH) carrying a connection message, and counting of available slots that are used for the repeated transmission of the physical channel. Additionally, the UE may be configured to indicate the capability for JCE through a demodulation reference signal (DMRS) configuration or a DMRS port.

Provided is a wireless communication terminal that wirelessly communicates with a base wireless communication terminal. The wireless communication terminal includes: a transceiver; and a processor. The processor is configured to receive trigger information and data from the base wireless communication terminal by using the transceiver, and transmits ACK information indicating whether the data is received to the base wireless communication terminal based on the trigger information. The trigger information is information for triggering transmission of the wireless communication terminal.
