Method and apparatus for determining the transmission setting instruction status

Abstract

The embodiments of the present disclosure disclose a method and apparatus for determining a transmission configuration indication state, which can be applied in the field of communication technology. The method performed by a terminal device includes the steps of receiving indication information, the indication information being used to indicate at least one set of transmission configuration indication (TCI) states, and determining a TCI state for transmission of the channel and / or signal based on at least one of a setting for the channel and / or signal, a number of TCI states indicated in the indication information, and a type of channel, so that after receiving the at least one set of TCI states, the terminal device determines a TCI state for transmission of the channel and / or signal based on information such as a setting for the channel and / or signal, and a number of TCI states indicated in the indication information, thereby keeping the TCI state for transmission of the channel and / or signal determined by the terminal device consistent with that determined by the network device, ensuring transmission reliability, and improving transmission quality.
