Short-Range Bearer Mapping for UE Cooperative Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In short range communications, there is a lack of distinction between radio bearers, which hinders differentiated Quality of Service (QoS) and data processing, especially in multiple UEs cooperative communication scenarios where uplink and downlink data cannot be effectively managed.
Innovation Solution
A method that establishes mappings between short range bearers and radio bearers on both user equipment (UE) and base station sides, allowing for the identification and processing of specific data bearers through unique identifiers, enabling differentiated QoS management.

Engineering Contradiction Analysis
1Reliability
If short range communication is used for cooperative communication between UEs, then communication reliability and throughput are improved, but the ability to distinguish radio bearers and provide differentiated QoS deteriorates
Solution Approach 1:
The patent segments the short range communication bearer into multiple logical bearers by introducing mapping relationships. Each radio bearer is mapped to a corresponding short range bearer, allowing differentiated QoS management while utilizing the unified short range communication link. This segmentation enables the system to maintain bearer distinction capability despite using short range communication technology that inherently lacks bearer concepts.
2Length of stationary object
If short range communication technology is used, then communication range is reduced to short distance, but the complexity of establishing bearer mappings and managing multiple UEs increases
Solution Approach 1:
The patent establishes mapping relationships between radio bearers and short range bearers in advance, before actual data transmission occurs. The base station configures these mappings proactively, so that when cooperative communication is initiated, the bearer relationships are already defined and ready for use. This preliminary action reduces the complexity of real-time bearer management during active communication.
3Productivity
If multiple UEs cooperative communication is implemented, then data transmission efficiency is improved, but the difficulty of managing uplink and downlink data bearers increases
Solution Approach 1:
The patent introduces the base station as an intermediary that manages and coordinates the bearer mappings between multiple UEs. The base station maintains the mapping relationships and provides instructions to UEs on which bearers to use for uplink and downlink data. This intermediary role simplifies bearer management for individual UEs while enabling efficient multi-UE cooperative communication.

AI summary
Embodiments of the present invention provide a short range communications method, device, and system, and relate to the field of communications, so that a UE can distinguish, on a short range link, a radio bearer corresponding to transmission of data information. The method includes: establishing, by a benefited UE, a mapping between a short range bearer and a first radio bearer, where a mapping is performed between the short range bearer and a second radio bearer on a supporting UE side, and a mapping is performed between the first radio bearer and the second radio bearer on a base station side; and performing, by the benefited UE, data receiving and sending by using the mapping between the first radio bearer and the short range bearer.
