Sidelink Control Signaling Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 4G mobile communication networks, base stations cannot allocate sending resources for sidelink control signaling, preventing user equipment (UE) from sending sidelink control signaling on sidelinks, which affects unicast connection management and reduces system reliability.
Innovation Solution
A resource determination method that uses pre-configured sending resource pool information to allocate a sending resource for sidelink control signaling, allowing UE to send the signaling on sidelinks, thereby managing unicast connections effectively and improving communication performance and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations allocate resources for sidelink data but not for sidelink control signaling, then resource allocation for data transmission is achieved, but unicast connection management capability is lost and system reliability deteriorates
Solution Approach 1:
The resource pool is segmented into control signaling resources and data resources, with separate configuration parameters (first sending resource pool configuration information vs. second sending resource pool configuration information). This allows independent management and allocation of control and data resources, resolving the contradiction by enabling reliable control signaling transmission without complicating the overall resource allocation system.
Solution Approach 2:
The base station performs preliminary action by pre-configuring and broadcasting the first sending resource pool configuration information before sidelink communication occurs. User equipment can then autonomously determine control signaling resources without real-time base station intervention, improving reliability while reducing allocation complexity during actual communication.
2Ease of operation
If user equipment sends sidelink control signaling on sidelinks, then unicast connection management is improved, but resource allocation complexity increases
Solution Approach 1:
The first sending resource pool configuration information acts as an intermediary, carrying resource allocation rules from the base station to user equipment. This intermediary structure simplifies the resource determination process by providing pre-defined allocation patterns that UE can follow autonomously, improving ease of operation without significantly increasing complexity.
Solution Approach 2:
User equipment performs self-service by autonomously determining control signaling resources based on the received configuration information and sending timing. The UE independently calculates the first sending resource using the formula involving offset values and sending timing, eliminating the need for complex real-time negotiation and simplifying connection management.

AI summary
A resource determination method includes: according to first sending resource pool configuration information that is obtained in advance, sending a first sending resource, wherein the first sending resource pool configuration information is used to characterize a sending resource pool sending a direct link control signaling, and the first sending resource is used for a first user equipment to send a first direct link control signaling to a second user equipment on a direct link; and sending the first direct link control signaling to the second user equipment by using the first sending resource. With the present technical solution, transmission resources are allocated to the direct link control signaling, so that the UE may send the direct link control signaling on the direct link, thereby effectively managing unicast connection, improving the performance of direct connection communication, and improving system reliability.
