Resource Partitioning for Joint Decoding in Wireless Downlink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, resource partitioning is challenging due to interference between downlink transmissions from different base stations, which hinders effective joint decoding by user equipment (UEs).
Innovation Solution
The system partitions resources into specific partitions and informs UEs of these partitions, enabling them to perform joint decoding by coordinating resource allocation and error control coding across multiple base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resources are shared between multiple base stations for downlink transmissions, then system capacity is improved, but interference between transmissions increases
Solution Approach 1:
The patent segments resources into distinct resource partitions that are allocated to different base stations. Each base station is assigned specific resource partitions (time-frequency resources) for downlink transmissions, which prevents interference while maintaining high system capacity through efficient resource utilization.
2Productivity
If joint decoding is performed by UEs for data from multiple base stations, then decoding efficiency is improved, but resource coordination complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring resource partitions and allocating them to base stations before downlink transmissions occur. This advance resource coordination simplifies the joint decoding process for UEs, as they can efficiently decode data from multiple base stations using the pre-established resource partition information without dealing with complex real-time coordination.

AI summary
Systems and methods are disclosed for partitioning resources into resource partitions, and informing user equipments (UEs) of the resource partitions. Knowledge of the resource partitions may assist the UEs in performing joint decoding. In one embodiment, a method performed by a UE includes receiving at least one message from each base station. The at least one message provides information indicating how resources are partitioned by the base station into a respective plurality of resource partitions. The information is used to identify respective resources for each of at least two downlink transmissions. Respective data that was transmitted on each of the at least two downlink transmissions using the respective resources is jointly decoded.
