Abstract: Example methods and apparatus for transmitting uplink control information are described. One example method includes receiving downlink control information by a terminal device, where the downlink control information includes resource information of a data channel, first indication information, and second indication information. The first indication information indicates a power offset value between a transmission time interval k and a transmission time interval k−1, and the second indication information is used to determine a power adjustment value in the transmission time interval k. The terminal device determines transmit power in the transmission time interval k based on the power offset value and the power adjustment value. The terminal device transmits uplink control information based on the transmit power, where the uplink control information includes feedback information for the data channel.

Abstract: Example control information transmission methods and apparatus are described. One example control information transmission method includes that a terminal device determines a transmission resource based on a receiving status of downlink data and a scheduling request transmission status. The transmission resource is one of N first resources or one of M second resources. The N first resources are corresponding to N receiving statuses of the downlink data, and the M second resources are used to transmit a scheduling request. N is a positive integer greater than 1, and M is a positive integer. The terminal device sends uplink control information on the transmission resource.

After an MCS index is selected for a terminal device, reduction processing is performed on the MCS index according to a preset MCS index reduction exponent, a reduced MCS index is indicated to the terminal device, frequency offset estimation is performed on the terminal device by using a recorded historical frequency offset value, and a PUSCH sent by the terminal device according to the reduced MCS index is demodulated after the frequency offset estimation. A frequency offset value is determined by using the prerecorded historical frequency offset value, so that the frequency offset value does not need to be determined in an existing manner of adding a DM-RS symbol to a 0.5-millisecond TTI.
