Terminal Identity Signaling in URAT for Reliable 6G Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 6G wireless communication systems, when a terminal in an RRC idle state initiates communication without an established connection, the network device cannot confirm the terminal's identity, affecting communication reliability.
Innovation Solution
The terminal sends identity information, including a terminal identifier and optional additional fields, to the network device before or during Uncoordinated Random Access And Transmission (URAT), using methods such as scrambling data with identity information or carrying it in the preamble or PUSCH data portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal sends identity information to the network device before or during URAT, then the network device can confirm the terminal's identity and communication reliability is improved, but the signaling overhead and protocol complexity increase
Solution Approach 1:
The patent combines identity information transmission with the URAT process by embedding the terminal identifier in the preamble sequence or PUSCH data. This merging approach allows the network device to obtain identity information during the existing random access procedure without requiring separate signaling messages, thus improving communication reliability while avoiding additional protocol complexity
Solution Approach 2:
The patent transmits identity information before or during the URAT process, allowing the network device to have the terminal identifier available before authentication and data transmission begin. This preliminary action ensures the network can properly associate and authenticate the terminal's subsequent communications without disrupting the established connection
2Measurement precision
If the terminal identifier is embedded in the preamble or PUSCH data, then accurate terminal identification is achieved, but the data structure and processing complexity increase
Solution Approach 1:
The patent merges the terminal identifier with existing data structures by embedding it in the preamble sequence indices or PUSCH data fields. This approach allows accurate terminal identification to be achieved by utilizing and extending existing communication protocols rather than creating entirely new data structures, thereby reducing processing complexity while maintaining identification accuracy
