Sidelink Resource Pool Configuration for Idle UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, UEs in idle or inactive states can only use broadcasted sidelink resource pools, leading to low resource utilization and competition for reserved resources, as the network lacks knowledge of the UE's service state to adjust resources effectively.
Innovation Solution
A method where the base station configures two sidelink resource pools, a first pool for use by UEs in idle or inactive states and a second pool for use after the first pool is released. The base station allocates these resources to UEs, allowing them to use dedicated sidelink resources instead of broadcasted resources, reducing competition and enabling better resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base station uses broadcasted sidelink resource pools for UEs in idle state, then all UEs can access sidelink resources, but resource utilization is low and competition for reserved resources is fierce
Solution Approach 1:
The patent divides the single broadcasted sidelink resource pool into two separate pools: a first sidelink resource pool for targeted UE allocation and a second sidelink resource pool for general broadcasted access. This segmentation allows differentiated resource management, reducing competition in the first pool while maintaining universal access capability through the second pool, thereby improving overall resource utilization.
Solution Approach 2:
The patent applies local quality by providing different resource pool characteristics to different UE groups. UEs receiving dedicated RRC releases get access to the first resource pool with tailored resource reservations based on their specific service requirements, while other UEs access the second resource pool with general broadcasted resources. This localized optimization reduces unnecessary competition and improves resource matching efficiency.
2Productivity
If the base station allocates dedicated sidelink resources to specific UEs, then competition for broadcast resources is reduced, but the base station needs to maintain and manage multiple resource pools
Solution Approach 1:
The patent implements preliminary action by pre-configuring both the first and second sidelink resource pools before UEs enter idle or inactive states. The base station prepares these resource pools in advance, so when UEs need sidelink resources, they can be quickly allocated from the pre-prepared first pool without requiring complex real-time resource pool creation or management during the idle state transition.

AI summary
Disclosed in embodiments of the present disclosure are a method and apparatus for resource processing, and a computer storage medium. The method comprises: configuring a first direct link resource pool and a second direct link resource pool, the first direct link resource pool being a resource pool of direct links that can be used by a user equipment (UE) after entering an idle state or an inactive state, and the second direct link resource pool being a resource pool of direct links that can be used by the UE in the idle state or the inactive state after the first direct link resource pool has been released; and sending information of the first direct link resource pool and information of the second direct link resource pool to the UE.
