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 terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.
