Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of cooperating UEs and transmission points increases in wireless networks, managing virtual transmitters and transceivers becomes complex, limiting the number of cooperating devices due to complexity and energy saving considerations, and dynamic reconfiguration is hindered by the need to maintain manageable complexity.
Innovation Solution
A system and method for device-centric transmitter and receiver virtualization, which involves selecting a cooperation candidate set (CCS) and determining a cooperation active set (CAS) from potential cooperating user equipment (CUEs) to form a virtual multipoint transceiver, using simple selection criteria like signal strength and location, and configuring based on long-term quality measurements to reduce complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of cooperating UEs and transmission points is increased to improve signal quality and throughput, then the coverage and reliability are improved, but the device complexity and management overhead increase
Solution Approach 1:
The patent segments the set of potential cooperating UEs into a cooperation candidate set (CCS) and a cooperation active set (CAS). The CCS contains all potential cooperating UEs, while the CAS is a selected subset that actually participates in the virtual multipoint transceiver. This segmentation allows the system to maintain a manageable number of active cooperators while having access to a larger pool of potential cooperators for future reconfiguration, thus resolving the contradiction between reliability and management complexity.
Solution Approach 2:
The patent implements dynamic reconfiguration of the virtual multipoint transceiver by allowing the target UE to request reconfiguration and the network to update the CAS based on changing network conditions. The system can dynamically adjust which UEs are in the CAS without requiring all UEs to remain permanently configured, enabling the system to adapt to varying reliability requirements while controlling complexity through on-demand reconfiguration rather than static comprehensive configuration.
2Adaptability or versatility
If dynamic reconfiguration of virtual transmitters is enabled to adapt to network conditions, then the adaptability is improved, but the complexity of the selection process increases
Solution Approach 1:
The patent performs preliminary action by pre-establishing the CCS of potential cooperating UEs before actual transmission occurs. This preliminary set is built based on basic criteria such as geographic location and signal strength measurements. When reconfiguration is needed, the system only needs to select from this pre-built CCS rather than evaluating all possible UEs from scratch, significantly reducing the complexity of dynamic reconfiguration while maintaining adaptability to network conditions.
Solution Approach 2:
The CCS acts as an intermediary structure between the network's reconfiguration needs and the actual selection of cooperating UEs. Instead of directly managing all potential UEs or performing complex evaluations during reconfiguration, the system uses the CCS as an intermediate layer that is pre-filtered and maintained, simplifying the reconfiguration process while still enabling adaptive selection based on current network conditions.
3Productivity
If the number of cooperating transmission points is increased to improve throughput, then the productivity is improved, but the energy consumption increases
Solution Approach 1:
The patent applies partial action by selecting only the necessary number of UEs to include in the CAS rather than involving all potential cooperators. The system determines the optimal size of the CAS that provides sufficient throughput improvement without requiring excessive numbers of active cooperating UEs. This partial participation approach balances productivity gains with energy consumption, as fewer active UEs consume less energy while still achieving the required throughput through coordinated transmission.

AI summary
A method embodiment includes receiving, by a network device, a cooperation candidate set (CCS) and determining a cooperation active set (CAS). The CCS includes a plurality of potential cooperating user equipment (CUEs) for selection to the CAS, and the plurality of potential CUEs is selected from a plurality of user equipment (UEs) in the network. The CAS is a set of CUEs selected from the CCS. A target user equipment (TUE) and the set of CUEs form a virtual multipoint transceiver.
