METHOD AND TERMINAL FOR SENDING FEEDBACK STATES

摘要

This invention discloses a method and terminal for sending feedback states. The method includes: Step 1, the terminal detects the physical downlink shared channel of M downlink component carriers to acquire the feedback states of N codeword streams of each downlink component carrier, wherein, M=1, N=2; Step 2, for each codeword stream of each downlink component carrier, the terminal performs logical AND operation on a feedback state of the nth codeword stream of each downlink component carrier to acquire the feedback information of a nth bit, wherein, 1=n=N; Step 3, the terminal sends the obtained N-bit feedback information using a preset manner on a preset physical uplink control channel (PUCCH). With the invention, the terminal can feed back the feedback state of each downlink component carriers only through one PUCCH channel so as to maintain the single-carrier property of the uplink.
