Abstract
Disclosed in the embodiments of the present application are a contention free random access method and device, for solving the problem that there are no solutions applicable to a contention free random access 2-step RACH and for performing data transmission by means of a PUSCH resource in a communication process. In the embodiments of the present application, a network side device sends, to a terminal, allocation information of a preamble code and/or a PRACH resource; and the terminal sends a random access request by means of the preamble code and/or the PRACH resource, and sends uplink data on a PUSCH resource corresponding to the preamble code and/or the PRACH resource. Said method provides a two-step random access method for contention free random access, and also provides a method for performing data transmission by means of a PUSCH resource when the contention free random access is performed.
