UE Cooperation Discovery via Availability Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing and optimizing finite wireless channel resources due to signal attenuation and blocking in complex and dynamic environments, which undermines established wireless channel measuring and reporting mechanisms.
Innovation Solution
The method involves a target user equipment (UE) receiving availability and assistance information from candidate UEs to establish a cooperation connection, facilitating UE discovery and resource sharing to improve communication capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE cooperation is implemented to improve spatial diversity and throughput, then communication reliability is improved, but device complexity increases due to the need for availability information exchange and cooperation connection establishment
Solution Approach 1:
The patent applies preliminary action by having candidate UEs broadcast their availability information and assistance information in advance before actual cooperation is needed. This allows target UEs to make informed decisions about cooperation without requiring complex real-time negotiation, thereby improving reliability while managing device complexity through proactive information disclosure.
Solution Approach 2:
The patent uses availability information and assistance information as intermediary elements that mediate between candidate UEs and target UEs. These information structures serve as standardized intermediaries that simplify the cooperation establishment process, enabling reliable cooperation connections without excessive device complexity by providing a common language for UE interaction.
2Ease of operation
If UE discovery mechanisms are enhanced through availability information broadcasting, then ease of operation is improved, but loss of energy increases due to continuous information transmission
Solution Approach 1:
The patent applies periodic action by having candidate UEs broadcast availability information at scheduled intervals rather than continuously. This periodic broadcasting maintains ease of operation by ensuring target UEs can discover cooperating candidates while reducing energy consumption compared to continuous transmission, as UEs can enter low-power states between broadcasting cycles.
Solution Approach 2:
The patent implements self-service by having candidate UEs autonomously broadcast their own availability and assistance information without requiring target UE initiation. This self-service approach improves ease of operation by making cooperation opportunities automatically discoverable while managing energy consumption through efficient broadcast timing and content, as each UE serves its own discovery needs without constant external prompting.

AI summary
Certain aspects of the present disclosure provide techniques for user equipment (UE) cooperation. Certain aspects provide a method for wireless communication by a target UE. The method generally includes receiving availability information indicating availability of one or more candidate UEs for cooperating with the target UE for communicating with a network entity, receiving assistance information from at least one of the candidate UEs, establishing a cooperation connection with the at least one of the candidate UEs based on the assistance information, and transmitting, to the network entity, an indication of UE capability based on the cooperation connection.
