Aspects relate to a terminal apparatus that uses a PUSCH that includes a transport block to transmit a HARQ-ACK, and that codes the HARQ-ACK. A number Q of coded modulation symbols of the HARQ-ACK is (i) an output of a max function to which Q.sub.temp and Q.sub.min are input, and (ii) an output of a min function to which 4.Math.M.sup.PUSCHsc is input; the M.sup.PUSCHsc is a scheduled bandwidth for transmission of the PUSCH in a subframe for the transport block and is represented by a number of subcarriers; the max function is a function configured to output a largest value among a plurality of input values; and the min function is a function configured to output a smallest value among a plurality of input values. Thus, the HARQ-ACK can be transmitted efficiently.

Disclosed herein is a method for transmitting a signal to or receiving a signal from a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving a first packet from the base station; transmitting, to the base station, a negative-ACK(NACK) response to the first packet; receiving a second packet from the base station and determining whether an error has occurred in the NACK response to the first packet; and transmitting, to the base station, information on whether an error has occurred in the NACK response to the first packet.

Various aspects related to ACK/NACK feedback for multi-TRP transmission scenarios are described. A base station, may send, to a UE, information indicating PDCCH monitoring occasions for each of a plurality of TRPs. In one aspect, the base station may send information indicating whether ACK/NACK feedback across the plurality of TRPs is allowed. The base station may send rules to the UE for performing ACK/NACK feedback bundling for providing feedback to the plurality of TRPs. The base station may also send information indicating a DAI definition for interpreting DAIs transmitted by the plurality of TRPs in corresponding PDCCH transmissions indicating whether the DAIs are independent or joint. The base station may receive a joint ACK/NACK feedback from the UE in a PUCCH based on the rules, or may receive multiple ACK/NACK feedback from the UE in a PUCCH for a first TRP independent from a second TRP.

Example wireless feedback control systems disclosed herein include a receiver to receive a first measurement of a target system via a first wireless link. Disclosed example systems also include a neural network to predict a value of a state of the target system at a future time relative to a prior time associated with the first measurement, the neural network to predict the value of the state of the target system based on the first measurement and a prior sequence of values of a control signal previously generated to control the target system during a time interval between the prior time and the future time, and the neural network to output the predicted value of the state of the target system to a controller. Disclosed example systems further include a transmitter to transmit a new value of the control signal to the target system via a second wireless link.

A method for transmitting uplink signals, which include ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ACK/NACK signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. Thus, the uplink signals can be transmitted to improve receiving reliability of signals having high priority.

Embodiments of the present disclosure provide a method and system for adjusting a physical uplink control channel (PUCCH) format in a wireless communication network. In particular, the method is implemented for adjusting a PUCCH format in an uplink transmission from a terminal device to a network device in a wireless communication network. The method comprises: using a first PUCCH format having a first duration for a service between the terminal device and the network device; and using (804) a second PUCCH format having a second and different duration for the service of the terminal device responsive to a determination that the first PUCCH format is in need of change based on one or more events.
