SINR Measurement Resource Mapping Around CORESET Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communications, the channel resource and interference resource conflict with the CORESET resource during SINR measurement, leading to incorrect reception of these resources.
Innovation Solution
Configure channel and interference resources on orthogonal frequency division multiplexing (OFDM) symbols other than those occupied by the CORESET, or use the same reception beam for channel, interference, and CORESET resources to avoid conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel resource and interference resource are configured on the same time-frequency resources as CORESET, then resource utilization is improved, but resource conflict occurs leading to incorrect reception
Solution Approach 1:
The patent resolves the resource conflict by introducing a spatial dimension solution - using different reception beams for channel/interference resources and CORESET resources. This allows overlapping time-frequency resources to be distinguished through spatial separation via beamforming, enabling correct reception without resource exclusion.
2Reliability
If channel resource and interference resource are configured to avoid CORESET resources, then reception accuracy is improved, but resource utilization deteriorates
Solution Approach 1:
Instead of avoiding CORESET resources in time-frequency domain, the patent utilizes the spatial dimension through beamforming to allow resource overlap. This maintains high resource utilization while ensuring accurate reception by distinguishing resources through different reception beams.
3Reliability
If different reception beams are used for channel/interference resources and CORESET resources, then resource conflict is resolved, but device complexity increases
Solution Approach 1:
The network device configures the terminal with multiple reception beams and indicates which beam to use for each resource through downlink control information. The terminal autonomously selects and switches between beams based on network instructions, reducing the need for complex manual beam management while ensuring reliable resource reception.

AI summary
A measurement and reporting method and apparatus are provided, to resolve a problem that a channel resource and an interference resource conflict with a CORESET resource when SINR measurement is performed. The method includes: receiving measurement configuration information from a network device, where the measurement configuration information is used to configure a channel resource and an interference resource; and when the channel resource and the interference resource meet a preset condition, the channel resource and the interference resource are configured on OFDM symbols other than an OFDM symbol occupied by a CORESET; and performing measurement based on the configured channel resource and interference resource, the CORESET is shunned when the channel resource and the interference resource are configured, to avoid a problem that the channel resource, the interference resource, and the CORESET cannot be correctly received because the channel resource and the interference resource conflict with the CORESET resource.
