UE Aggregation Uplink Scheduling for Coverage-Limited Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in enhancing coverage and reducing power consumption of communication devices, particularly in the allocation of time and frequency resources for wireless signal transmission.
Innovation Solution
A method involving user equipment (UE) aggregation, where a second UE transmits data to a base station (BS) using a transmission configuration obtained from a first UE, allowing simultaneous or coordinated data transmission without the BS needing significant modification, and utilizing dynamic or semi-static scheduling of Physical Uplink Shared Channel (PUSCH) based on configuration information from the first UE.

Engineering Contradiction Analysis
1Reliability
If a second UE transmits data for a first UE using the first UE's transmission configuration, then coverage and performance of uplink control channels are improved, but device complexity increases due to coordinated transmission requirements
Solution Approach 1:
The second UE acts as an intermediary device that receives transmission configuration from the first UE and performs coordinated transmission to the base station. This mediator approach allows the first UE to benefit from enhanced coverage without directly managing the complex transmission coordination, while the second UE handles the operational complexity of executing the coordinated transmission using the first UE's configuration parameters.
2Productivity
If dynamic or semi-static scheduling of PUSCH is used based on first UE configuration, then productivity and resource allocation efficiency are improved, but device complexity increases due to scheduling configuration requirements
Solution Approach 1:
The transmission configuration obtained by the second UE is designed to be universal and multi-functional, serving both the second UE's own transmission needs and the first UE's data transmission requirements. The scheduling mechanism uses a unified configuration framework that can dynamically allocate resources for different UEs without requiring separate complex configuration systems, thereby improving resource allocation efficiency while managing device complexity through standardized configuration procedures.

AI summary
Wireless communication methods are disclosed. A wireless communication method includes obtaining, by a second user equipment (UE), a transmission configuration corresponding to a first user equipment for transmitting the data from the first UE; and transmitting, by the second UE, the data to a base station (BS) according to the transmission configuration.
