Wireless Resource Allocation for Unidentified UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G networks, there is a challenge in efficiently allocating resources for sidelink communications, especially when user equipment (UE) is not identified to the network, which hinders effective resource management and allocation.
Innovation Solution
A method where a first wireless device receives a resource request from a second wireless device, allocates an identifier to the second device, and forwards this request to the network, allowing the network to allocate resources even if the UE is not identified, by transmitting a message with the resource configuration back to the second device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network directly allocates resources to UE performing sidelink communication, then resource allocation can be done, but the UE must be identified to the network which limits applicability to unidentified UEs
Solution Approach 1:
The serving UE acts as an intermediary between the network and the second UE. It receives resource requests from the second UE, forwards them to the network with its own identification, and relays the network's resource allocations back to the second UE. This mediator approach enables unidentified UEs to obtain resources without direct network identification.
Solution Approach 2:
The serving UE uses its own established connection and identification with the network to secure resources for itself and the second UE. Instead of requiring the second UE to be directly identified, the serving UE leverages its own network credentials to obtain resources on behalf of both devices.
2Adaptability or versatility
If the first wireless device forwards resource requests for the second device, then resource allocation is enabled for unidentified UE, but additional signaling messages are required
Solution Approach 1:
The patent combines multiple functions into single signaling messages. The serving UE embeds the second UE's resource requests within its own uplink transmissions to the network, and consolidates resource allocation information when forwarding back to the second UE. This merging reduces the number of separate signaling exchanges needed.
Solution Approach 2:
The serving UE performs preliminary actions by pre-establishing its connection and identification with the network before needing to secure resources for the second UE. This preliminary setup enables it to quickly forward resource requests without requiring the network to first identify or authenticate the second UE.

AI summary
A method performed by a first wireless device in a wireless communication system including receiving, from a second first wireless device, a first message comprising information for requesting a resource allocation to the second wireless device; transmitting, to a network, a second message comprising a resource request for the second wireless device, the resource request comprising the information and an identifier (ID) of the second wireless device allocated by the first wireless device; receiving, from the network, a third message comprising a resource configuration for the second wireless device, the resource configuration comprising information for a resource for the second wireless device related to the resource request, and the ID of the second wireless device; and transmitting, to the second wireless device, a fourth message comprising the resource configuration related to the ID of the second wireless device.
