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.

Abstract: Disclosed are a method and device for transmitting data and indicating data transmission, relating to the technical field of wireless communications and used for solving the problem in the prior art of a terminal device being unable to preferentially transmit data with special requirements of a resource, a time delay, etc., when data of different types is transmitted or received and a resource collision occurs. The present application comprises: receiving at least one priority threshold indicated by a network side and associated with a first channel, wherein the at least one priority threshold comprises a first priority threshold; and when the first channel overlaps with a second channel, determining, according to a first priority of the first channel and the first priority threshold, whether to transmit or obtain first data, wherein the first channel is used for transmitting or obtaining the first data, and the second channel is used for transmitting or obtaining second data.
