Random Access Resource Sharing for Mixed-Capability Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack flexibility in resource configuration during random access procedures, particularly for terminals with varying capability types, such as reduced capability terminals like wearable devices, leading to inefficiencies and potential communication performance issues.
Innovation Solution
Implementing a resource configuration method where terminals of different capability types share at least some resources, allowing them to select a target resource and optionally indicate their capability type through random access information, enabling the network device to identify and schedule them accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate resource sets are configured for different capability types, then terminal identification accuracy is improved, but resource configuration flexibility deteriorates
Solution Approach 1:
The patent segments random access resources into first and second resource sets corresponding to different capability types (e.g., enhanced capability terminals and normal capability terminals). This segmentation enables the network to identify terminal types accurately while maintaining flexible configuration through shared resources. The segmentation is implemented through configuration information that indicates which resources belong to which capability type, allowing precise terminal differentiation without rigid resource allocation.
2Adaptability or versatility
If shared resources are configured for multiple capability types, then resource configuration flexibility is improved, but terminal identification accuracy deteriorates
Solution Approach 1:
The patent implements universality by configuring shared resources that can be used by multiple capability types. The configuration information indicates that certain resources are shared between enhanced capability terminals and normal capability terminals, allowing these resources to serve multiple functions. This multi-functionality approach improves resource utilization flexibility while the network maintains identification capability through additional signaling mechanisms.
3Manufacturing precision
If capability type indication is added to random access information, then scheduling accuracy is improved, but information transmission complexity increases
Solution Approach 1:
The patent applies preliminary action by incorporating capability type indication directly into the random access information transmitted during the initial random access procedure. This allows the network to identify terminal capability types early in the communication process, enabling accurate scheduling before subsequent data transmission begins. The capability indication is included in the random access message structure, allowing the network to prepare appropriate scheduling parameters in advance.

AI summary
A communication method includes: obtaining configuration information, where the configuration information indicates a resource set, the resource set includes a first resource set and/or a second resource set, a resource in the first resource set may be used by a terminal of a first capability type to send a preamble, a resource in the second resource set may be used by a terminal of a second capability type to send a preamble, and the first resource set and the second resource set share at least some resources; selecting a target resource from the resource set, and sending a preamble by using the target resource; then receiving a random access response; and sending first random access information when the shared at least some resources include the target resource, where the first random access information may indicate a capability type of the terminal.
