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.

Abstract: A data transceiving method includes: receiving a first reference signal transmitted on a subcarrier in a target physical resource block, and performing, according to a first mapping rule, corresponding processing on the first reference signal received from the subcarrier in the target physical resource block, where the first mapping rule defines at least mapping of the first reference signal to 10 specified subcarriers in a physical resource block, none of the 10 specified subcarriers are in a DC subcarrier candidate set, and the first reference signal includes a PCRS. In the embodiments of this application, only the 10 specified subcarriers in the physical resource block that are not used as DC subcarriers are selected to transmit the first reference signal, and no additional DC subcarrier is set. In this way, a quantity of downlink subcarriers in a system does not change dynamically.

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: The present disclosure discloses a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.

Abstract: The present disclosure relates to a method and a device for sending and receiving information. The method includes: determining a frame structure of a serving cell, where a radio frame corresponding to the frame structure includes at least one first special subframe, remaining subframes are downlink subframes, and the first special subframe includes symbols used for uplink transmission and downlink transmission, and a GP; and sending and receiving information in the serving cell based on the frame structure. In the technical solution, because the radio frame structure includes the first special subframe, when spectrum resources are maximally applied to downlink data service transmission, not only performance of massive MIMO is improved, but also the serving cell is enabled to work independently.

Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a method for sending and receiving information. The user equipment in embodiments of the present invention may determine a frame structure of a serving cell, where in addition to an uplink subframe and a downlink subframe, the frame structure in the embodiments of the present invention further includes a first subframe, and the first subframe includes a first symbol used for downlink transmission, a first GP, and a second symbol used for uplink transmission. More symbols used for downlink transmission and more symbols used for uplink transmission than those in a frame structure in the prior art are introduced by introducing the first subframe, thereby improving downlink transmission and effectively reducing a value of k, that is, reducing a service delay in feeding back a HARQ-ACK.
