Solution Overview

Problem

Existing wireless communications systems face inefficiencies in channel measurement processes by network-controlled repeaters (NCRs), which consume significant power and processing resources at user equipment (UEs) and incur signaling overhead.

Innovation Solution

NCRs receive control signaling from a network entity to perform channel measurements on non-overlapping sub-bands, transmitting these measurements back to the network entity, thereby reducing the burden on UEs and optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If UEs perform channel measurements on component carriers, then channel measurement capability is maintained, but power consumption and processing resources at UEs increase significantly

Engineering Contradiction:
Improvechannel measurement capabilityVSAvoidpower consumption at UE
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent introduces the NCR as an intermediary device that performs channel measurements on behalf of UEs. The NCR receives configuration from the network entity, conducts the measurements on specified sub-bands, and reports results to both the network entity and relevant UEs, thereby eliminating the need for UEs to directly perform these measurements and reducing their power consumption.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the channel measurement function from the UE and relocates it to the NCR. By separating this specific measurement task from the UE's responsibilities and assigning it to the NCR, the system reduces the computational burden and power consumption at the UE while maintaining the necessary measurement capabilities.

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If UEs perform channel measurements on component carriers, then channel measurement capability is maintained, but processing resources at UEs increase significantly

Engineering Contradiction:
Improvechannel measurement capabilityVSAvoidprocessing resources at UE
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The NCR acts as an intermediary that handles the complex channel measurement processing. Instead of requiring UEs to perform sophisticated channel measurements and analysis, the NCR receives measurement configurations, executes the measurements, processes the results, and provides feedback to both the network entity and UEs, thereby simplifying the UE's processing requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the computationally intensive channel measurement processing from the UE and transfers it to the NCR. This separation of functions reduces the processing complexity at the UE while maintaining the system's overall measurement capability through the NCR's processing power.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If NCR performs channel measurements on non-overlapping sub-bands, then resource utilization is optimized, but signaling overhead increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidsignaling overhead
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent segments the frequency spectrum into non-overlapping sub-bands for channel measurements. By dividing the available spectrum into distinct measurement bands, the system can efficiently allocate resources across different frequency ranges simultaneously, improving overall resource utilization while managing signaling overhead through structured reporting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements partial channel measurements by focusing only on specific non-overlapping sub-bands rather than the entire frequency spectrum. This selective measurement approach improves resource utilization efficiency by concentrating measurements on relevant bands while reducing the total measurement burden, thereby managing signaling overhead more effectively.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Methods, systems, and devices for wireless communications are described. Techniques described herein provide channel measurements determined by a network-controlled repeater (NCR). In some examples, the NCR may receive, from a network entity via a serving cell associated with the NCR, control signaling indicating the one or more sub-bands for a channel measurement on a component carrier associated with a network-controlled forwarding. The one or more sub-bands may be at least partially non-overlapping with a frequency range associated with the serving cell. The NCR may transmit, to the network entity the channel measurement associated with the one or more sub-bands. The NCR may relay signaling over the one or more sub-bands based at least in part on transmitting the channel measurement.
