Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: A method includes: when a band, in which a supplemental uplink (SUL) carrier is located, multiplexes a time-division duplex (TDD) band or a low-frequency frequency-division duplex (FDD) band, M time domain resources used by a terminal device to perform SUL transmission is determined from N time domain resources included in the SUL carrier, and indication information that indicates the M time domain resources is sent to the terminal device such that the terminal device can send an uplink signal and/or an uplink channel using the M time domain resources. Further, a network device may configure an available time domain resource used for uplink transmission for the SUL carrier using a system information block (SIB), Radio Resource Control (RRC) dedicated signaling, or download control information (DCI)/media access control (MAC) control element (CE).

Abstract: According to one embodiment, a terminal device receives downlink control information that is sent by a network device and that indicates a first physical downlink control channel (PUCCH), where the first PUCCH and a second PUCCH occupy a same first time-domain symbol, and the first PUCCH and a third PUCCH occupy a same second time-domain symbol; and the terminal device sends the first PUCCH, where the first PUCCH carries a first sequence and a second sequence, a cyclic shift of the first sequence is determined based on a hybrid automatic repeat request-acknowledgment (HARQ-ACK) value and state information of a scheduling request (SR) corresponding to the second PUCCH, and a cyclic shift of the second sequence is determined based on the HARQ-ACK value and state information of an SR corresponding to the third PUCCH. An HARQ-ACK and a plurality of SRs can be multiplexed on a same PUCCH improving communication efficiency.
