SEMI-DUPLEX METHOD OF DUPLEX COMMUNICATION WITH FREQUENCY SEPARATION, BASE STATION, AND TERMINAL Russian patent published in 2017 - IPC H04L27/26 H04W72/12 

FIELD: radio engineering, communication.

SUBSTANCE: at a time when the terminal switches from the downlink subframe to the adjacent uplink subframe, generating a first protection period where it is determined that the terminal does not process any signal in the first protection period, i.e., the terminal does not receive downlink data and does not send data Uplink in the first protection period, and therefore, it is possible to avoid the uncertainty of the behavior of the terminal during its switching from the downlink to the uplink, and the successful sending of the subframe is guaranteed Exalted communication; And when the terminal switches from the uplink subframe to the downlink subframe, generating a second guard period where the second guard period overlaps the uplink subframe or the downlink subframe, and it is determined that the terminal does not process any signal in the second guard period, It is possible to avoid the uncertainty of the behavior of the terminal during its switching from the uplink to the downlink.

EFFECT: increasing the reliability of communication by eliminating the uncertainty of the terminal's behavior during its switching from uplink to downlink.
