Solution Overview

Problem

User Equipment (UE) fails to utilize reference signal resources effectively due to RS being mapped to multiple access points, resulting in decreased measuring capability.

Innovation Solution

A method where the UE and base station process reference signals by determining and transmitting a first reference signal resource set, allowing the UE to perform co-location assumption processes for antenna ports indicated by each resource, thereby improving measurement capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If reference signal resources are mapped to multiple access points to enable coordinated multiple points service, then the service coverage and coordination capability are improved, but the user equipment cannot utilize the reference signal resources to perform measurements, resulting in decreased measuring capability

Engineering Contradiction:
Improvecoordinated multiple points service capabilityVSAvoidmeasuring capability of UE
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments reference signal resources into two distinct types: first reference signal resources for CoMP measurements where co-location assumption is performed, and second reference signal resources for CSI measurements where co-location assumption is not performed. This segmentation allows the UE to differentiate between measurement types and apply appropriate processing, resolving the contradiction by enabling both CoMP service capability and accurate measurement capability through dedicated resource allocation for each measurement purpose

AI summary

The present invention provides a method for processing a reference signal, a user equipment, and a base station. The method includes: obtaining, by a UE, a first reference signal resource set, where the first signal resource set includes at least one first reference signal resource; and executing, by the UE, an operation of performing a co-location assumption process for at least one antenna port indicated by each first reference signal resource.
