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.

The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.
