Embodiment Construction

[0121] Before introducing the technical solutions of the embodiments of the present invention, the related technologies will be described first.

[0122] During the random access process, the terminal can initiate a four-step random access, which specifically includes: Step 1, the terminal sends an uplink signal containing a preamble (Preamble) on the resources of the physical random access channel (PRACH, Physical Random Access Channel) , called Msg1; Step 2, the terminal receives the Random Access Response (RAR, Random Access Response) sent by the base station side, called Msg2; Step 3, the terminal sends uplink data on the uplink time-frequency resource indicated by the RAR, called Msg3 ; Step 4, the terminal receives the downlink data sent by the base station side, the downlink data contains information related to contention resolution, called Msg4. In order to reduce the random access delay, the terminal can also initiate two-step random access. figure 1 is a schematic d...

Abstract

The invention discloses an information transmission method and device, related equipment and a storage medium. The method comprises the following steps: network equipment receives first information reported by a terminal in a random access process; the first information comprises related information of at least one reference signal; the related information comprises an index value of the reference signal, or the index value of the reference signal and the signal quality of the reference signal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an information transmission method, device, related equipment and storage medium. Background technique [0002] During the random access process, the terminal can initiate four-step random access or two-step random access. During the random access process initiated by the terminal, the terminal measures the reference signal to obtain the signal quality; when the signal quality is greater than When the threshold is preset, the terminal initiates random access in the random access resource corresponding to the corresponding reference signal. Usually, the information reported by the terminal during the random access process is mainly used by the network side to identify the identity of the terminal. However, when resources used for downlink transmission are subsequently allocated after the random access process succeeds, problems such as resource waste and data transmi...
