Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and particularly to a method, apparatus, device, and storage medium for multi-Physical Random Access Channel (PRACH) transmission configuration.

Background Art

[0002] In a communication system, if the uplink coverage is low, it will affect the communication quality between the terminal device and the network-side device. One of the factors affecting the uplink coverage is the PRACH channel. Since the terminal device can only transmit one first message Msg1 in one random access attempt, the coverage of the PRACH channel becomes poor. Therefore, in order to improve the coverage of the PRACH channel by enabling the network-side device to receive the multi-PRACH transmission of contention-free random access (CFRA) and / or the multi-PRACH transmission of contention-based random access (CBRA) started by the terminal device based on the multi-PRACH transmission configuration, a method for "multi-PRACH transmission configuration" is urgently needed.
