Random Access Method Merging Preamble and Identity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The duration of the random access process for initiating data transfer between user equipment and a base station is excessively long, leading to communication delays.
Innovation Solution
A method where user equipment transmits a preamble and identity to the base station, receiving a message with multiple information units indicating different results of the random access, allowing the user equipment to perform corresponding operations, thereby reducing the duration of the random access process.

Engineering Contradiction Analysis
1Loss of time
If the traditional random access process is used, then the communication connection can be established, but the duration of the random access process is excessively long causing communication delays
Solution Approach 1:
The patent combines the random access preamble transmission and identity transmission into a single message (MSG1), and merges the random access response and contention resolution into a single message (MSG2) from the base station. This consolidation of multiple communication steps into fewer exchanged messages directly reduces the random access process duration and eliminates communication delays.
2Ease of operation
If multiple messages are exchanged for random access, then the connection establishment can be completed, but the number of messages increases causing longer duration
Solution Approach 1:
The patent merges multiple traditional random access messages into two consolidated messages: MSG1 containing both preamble and identity, and MSG2 containing both random access response and contention resolution. This reduction from four traditional messages to two messages simplifies the operation while simultaneously reducing the time duration of the random access process.

AI summary
A random access method, a random access apparatus, an electronic device and a computer-readable storage medium are disclosed. The method includes: initiating random access by transmitting a preamble and an identity to a base station; receiving a message fed back by the base station for the preamble and the identity, in which the message includes at least one information unit, and different information units are configured to indicate different results of initiating random access through the user equipment; and performing an operation corresponding to a result of initiating random access indicated by the information unit in the message.
