  • Publication number: 20210176789
    Abstract: A terminal apparatus receives first information for identifying one or multiple random access channel occasions, and receives second information for identifying an index of a random access preamble. In a case that a first condition is satisfied, the terminal apparatus selects, from one or multiple reference signals, one reference signal based on a measurement of each of the one or multiple reference signals. In a case that a second condition is satisfied, the terminal apparatus selects one reference signal of the one or multiple reference signals associated with a PDCCH used to receive the second information. The terminal apparatus selects, from the one or multiple random access channel occasions, one random access channel occasion associated with the one reference signal selected.
