Abstract: An initial access method and an apparatus are provided. In the method, an RS set corresponding to an SSB is introduced. The SSB is sent by using a wideband and a wide beam, and an RS in the RS set occupies a small quantity of time domain resources through frequency division multiplexing and is sent by using a narrow beam. A transmit beam of the RS in the RS set is a refinement of a transmit beam of the SSB. Narrow beam training is completed by using the RS set, to find an optimal narrow beam pointing to a UE, so that in the method, time domain resource overheads of the SSB can be effectively reduced while communication efficiency is ensured.

Abstract: A communication method and apparatus. for indicating indicate A terminal is indicated to perform second transmission when an SSB or a PRACH on a frequency domain resource overlaps with reverse transmission on another frequency domain resource in time domain. In response to the SSB or the PRACH overlapping with the second transmission in time domain, the terminal device determines, by receiving first indication information, that a priority of the SSB or the PRACH is lower than a priority of the second transmission on an overlapped time domain resource. The terminal device performs the second transmission based on the first indication information. The terminal device performs reverse transmission on a symbol that overlaps with the SSB or the PRACH.
