Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource allocation for peer-to-peer communications, leading to increased interference and idle transmission times, particularly in multiplexing control and data resources.
Innovation Solution
The proposed solution involves configuring user equipment (UEs) to dynamically reserve and multiplex control resources with data resources within a shared resource pool, allowing for concurrent data transmission and control message processing, and using beam training procedures to optimize communication links.

Engineering Contradiction Analysis
1Ease of operation
If control resources are separated from data resources in time, then control signaling can be processed independently, but transmission resources remain idle during control blocks causing reduced system efficiency
Solution Approach 1:
The patent merges control resources and data resources within the same time-frequency resources. Control messages and data transmissions share the same resource pool, allowing UEs to transmit control information (such as sidelink feedback, buffer status reports) and data simultaneously without leaving resources idle. This eliminates the waste of separating control and data into distinct time blocks while maintaining independent processability through resource allocation mechanisms.
Solution Approach 2:
By multiplexing control and data resources, the patent ensures continuous utilization of transmission resources. Instead of having idle periods during control blocks, the system maintains continuous data transmission and control signaling processing. UEs can dynamically allocate resources within the shared pool to ensure that control messages are processed independently while data transmission continues uninterrupted, maximizing system productivity.
2Object-affected harmful factors
If UEs transmit control messages and data sequentially in separate resources, then interference is reduced, but transmission time increases and power consumption rises
Solution Approach 1:
The patent segments the shared resource pool into different resource types (control resources and data resources) that can be dynamically allocated. UEs are assigned specific resource allocations within the shared pool for control signaling and data transmission. This segmentation allows control messages and data to be transmitted simultaneously in different resource allocations, reducing transmission time while managing interference through orthogonal resource assignment and collision avoidance mechanisms.
Solution Approach 2:
The patent implements dynamic resource allocation where UEs can flexibly select and switch between control and data resources based on instantaneous channel conditions and traffic requirements. This dynamic approach allows the system to optimize the balance between interference management and transmission efficiency in real-time, reducing overall transmission time and power consumption compared to static sequential transmission.
3Reliability
If UEs use dedicated control resources exclusively, then control signaling reliability is improved, but resource utilization efficiency decreases
Solution Approach 1:
The patent creates a universal shared resource pool that serves multiple functions - both control signaling and data transmission. The same resource pool is used for both control messages (feedback, buffer status, scheduling requests) and data transmissions. This multi-functional approach maintains control signaling reliability through dedicated resource allocations within the shared pool while simultaneously improving overall resource utilization efficiency by eliminating idle resources.
Solution Approach 2:
The patent enables UEs to autonomously manage their own resource allocations within the shared pool. UEs can independently select appropriate resources for control signaling and data transmission based on their specific needs and channel conditions. This self-service mechanism ensures that control signaling receives adequate resources for reliable transmission while maximizing overall resource utilization without requiring exclusive dedicated allocations.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A set of user equipments (UEs) may communicate with each other on communication links using data resources from a pool of shared resources. The UEs may be configured to multiplex control resources with data resources of a shared resource pool. In some cases, a UE may communicate, in control resources, control signaling to reserve data resources of a shared resource pool. After transmitting the request, the UE may communicate data in one or more data resources. The UE may communicate the data using transmission components while concurrently processing control signaling using other components.
