UE Cooperation Configuration for Antenna Panel Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, interference between user equipment (UE) and network nodes can limit network throughput and increase latency, as existing techniques often treat multiple antenna panels on UEs as separate entities rather than a unified configuration.
Innovation Solution
The described techniques enable UE cooperation by configuring multiple antenna panels across UEs as a single entity, allowing them to communicate messages between a base station and multiple UEs, with the base station transmitting control signaling to identify the appropriate antenna panel for message reception and transmission, thereby improving communication efficiency.

Engineering Contradiction Analysis
1Productivity
If multiple antenna panels on UEs are treated as separate entities, then device complexity is reduced and ease of operation is improved, but network throughput is limited and latency increases
Solution Approach 1:
The patent merges multiple antenna panels across different UEs into a unified configuration entity. The base station configures a set of antenna panels belonging to multiple UEs as a single entity, allowing centralized control and coordination. This merging enables the system to achieve higher network throughput by treating the distributed antenna panels as a coordinated array, while the base station manages the complexity through unified configuration messaging.
2Loss of time
If multiple antenna panels on UEs are treated as separate entities, then ease of operation is improved, but latency increases
Solution Approach 1:
By merging multiple antenna panels into a unified configuration entity managed by the base station, the system reduces latency through coordinated transmission and reception. The base station can optimize resource allocation and scheduling across all antenna panels simultaneously, eliminating the need for separate coordination procedures that would increase latency.
3Productivity
If antenna panels are configured as a single entity across multiple UEs, then network throughput is improved, but interference between UE and network node increases
Solution Approach 1:
The patent applies local quality by enabling the base station to configure different communication parameters for different antenna panels within the unified entity. Each antenna panel can be optimized for its specific spatial location and channel conditions, allowing the system to achieve high throughput while managing interference through localized parameter adjustment rather than uniform configuration.
Solution Approach 2:
The unified antenna panel configuration enables dynamic resource allocation and beamforming adjustments. The base station can dynamically control the transmission and reception characteristics of each antenna panel based on real-time channel conditions, user positions, and interference levels, thereby optimizing throughput while minimizing interference.
4Productivity
If antenna panels are configured as a single entity across multiple UEs, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The base station acts as an intermediary that manages the complexity of configuring multiple antenna panels as a unified entity. Instead of requiring complex peer-to-peer coordination between UEs, the base station sends unified configuration messages to multiple UEs, simplifying the implementation while achieving high communication efficiency through coordinated operation.

AI summary
Methods, systems, and devices for wireless communications are described. In some examples, a first user equipment (UE) may receive an active communication configuration between the first UE and a base station. The first UE may receive a UE cooperation configuration between at least the first UE and a second UE. The UE cooperation configuration may include a configuration for communicating messages between the base station and a set of antenna panels corresponding to at least the first UE and the second UE as a single entity. The UE cooperation configuration may include parameters associated with the second UE. The first UE may identify, from the set of antenna panels, an antenna panel for reception of a downlink message based on the UE cooperation configuration. The first UE may transmit a message to the base station, the second UE, or both in response to the downlink message.
