Abstract
In the field of communication technologies, a random access preamble sending method and a communication apparatus are provided to avoid a problem that a conflict exists between a PRACH time-frequency resource occupied by a terminal device for sending a random access preamble and a PUSCH time-frequency resource occupied by another terminal device for sending uplink data, and consequently a network device cannot normally receive the random access preamble and the uplink data. The method includes: a terminal device receives configuration information sent by a network device, where the configuration information includes configuration information of a PRACH time-frequency resource set and configuration information of a PUSCH time-frequency resource set. The terminal device determines, in the PRACH time-frequency resource set, a PRACH time-frequency resource that does not conflict with the PUSCH time-frequency resource set. The terminal device sends a random access preamble on the determined PRACH time-frequency resource.
