Sidelink Scheduling Requests With Dedicated Resource Sets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-capability UEs in sidelink communication systems face inefficiencies due to the resource-intensive process of monitoring large ranges of sidelink resources for scheduling information and transmitting requests, which is costly in terms of processing and tuning.
Innovation Solution
The solution involves configuring dedicated sets of resources for UEs to transmit requests and receive scheduling information, reducing the need for extensive resource monitoring and allowing for sequence-based or buffer status report-based requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low-capability UEs monitor large ranges of sidelink resources for scheduling information, then scheduling information can be received, but processing and communication resources are excessively consumed
Solution Approach 1:
The patent segments the sidelink resources into two distinct sets: a first set configured for transmitting scheduling requests and a second set configured for receiving scheduling information. This segmentation allows low-capability UEs to focus their monitoring and transmission activities on specific resource subsets, thereby reducing the overall resource range they must monitor while ensuring reliable communication.
2Adaptability or versatility
If low-capability UEs monitor large ranges of sidelink resources, then scheduling information coverage is complete, but device complexity increases
Solution Approach 1:
By dividing sidelink resources into dedicated transmission set and reception set, the patent reduces the monitoring complexity for low-capability UEs. Each UE only needs to monitor its configured reception set for scheduling information and use its configured transmission set for requests, rather than monitoring all possible sidelink resources.
3Use of energy by moving object
If dedicated resource sets are configured for request transmission and scheduling information reception, then resource monitoring range is reduced, but resource allocation efficiency improves
Solution Approach 1:
The patent implements preliminary configuration of resource sets by the network before sidelink communication occurs. The network configures each low-capability UE with specific first set resources for request transmission and second set resources for scheduling information reception in advance, allowing UEs to operate efficiently without real-time resource negotiation.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a request for a sidelink resource allocation. The UE may receive scheduling information identifying the sidelink resource allocation. Numerous other aspects are provided.
