Abstract

Embodiments of the present invention provide an information sending method, a terminal, and a network device. The method includes: receiving configuration information of a two-step random access process sent by a network device; selecting a preamble sequence according to the terminal and the configuration information, obtain at least one of a time-frequency resource for sending the physical uplink shared channel PUSCH and a demodulation reference signal DMRS port for sending the PUSCH; and send the PUSCH. The solution of the present invention can save the time-frequency resources reserved for MsgA PUSCH transmission and the signaling overhead for indicating the position of the time-frequency resources.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to an information sending method, a terminal and a network device. Background technique [0002] In the current NR R15 standard, the process for a terminal to initiate Contention-based Random Access (CBRA) is roughly as follows: [0003] 1) The terminal sends an uplink signal including a preamble sequence (Preamble) on the resource of the Physical Random Access Channel (PRACH, Physical Random Access Channel), which is called Msg1; [0004] 2) The terminal receives a random access response (RAR, Random Access Response) sent by the network side, which is called Msg2; [0005] 3) The terminal sends uplink data on the uplink time-frequency resource indicated by the RAR, which is called Msg3; [0006] 4) The terminal receives downlink data sent by the network side, and the downlink data includes contention resolution related information, which is called Msg4. [00...
