UE Antenna Panel Mapping via SRS for Uplink Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle with accurate uplink beam management due to the lack of a deterministic mapping relationship between sounding reference signal (SRS) resource sets and antenna panels in user equipment (UE), leading to inefficiencies in beam management.
Innovation Solution
Implementing a predetermined rule to define the mapping relationship between SRS resource sets and antenna panels, enabling the base station to determine which SRS resource set is utilized by each antenna panel of the UE, thereby facilitating more accurate beam management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple antenna panels emit beams simultaneously in different spatial directions, then uplink beam management coverage is improved, but the base station cannot accurately determine which SRS resource set is utilized by each antenna panel
Solution Approach 1:
The patent introduces a predetermined rule as an intermediary mechanism that establishes the mapping relationship between SRS resource sets and antenna panels. This rule acts as a mediator that allows the base station to infer which antenna panel used which SRS resource set without requiring explicit signaling, thus resolving the information loss problem while maintaining simultaneous beam emission capability
Solution Approach 2:
The patent enables the system to self-determine the mapping relationship between SRS resource sets and antenna panels through the predetermined rule. The base station can independently identify which antenna panel utilized which SRS resource set without requiring additional feedback or signaling from the UE, achieving self-service information retrieval
2Measurement precision
If a predetermined rule is established to map SRS resource sets to antenna panels, then beam management precision is improved, but system complexity increases
Solution Approach 1:
The patent changes the parameter of system configuration by introducing a predetermined mapping rule that associates SRS resource sets with antenna panels. This parameter change enables precise beam management by providing the base station with deterministic information about which antenna panel used which SRS resource set, while the complexity is managed through standardized configuration rather than ad-hoc setup
