Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently coordinating measurement resources and determining the simultaneous receiving (RX) beams capability of user equipment (UE) for L3 and L1 measurements across multiple carriers.
Innovation Solution
The proposed solution involves a UE device with antennas, a transceiver, and a processor that determines its simultaneous RX beams capability and assigns measurement resources accordingly. This includes receiving a measurement configuration from a base station, determining the RX beams capability, and coordinating measurement resources such as searchers and RX beams across carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the UE uses a single RX beam for measurements on a single carrier, then the measurement process is simpler and requires fewer resources, but the measurement time period becomes longer
Solution Approach 1:
The patent segments the measurement process by introducing multiple RX beams (first RX beam and second RX beam) for performing measurements on the same carrier. This segmentation allows parallel measurement operations across different beams, reducing the overall measurement time period while maintaining manageable complexity through structured resource assignment.
Solution Approach 2:
The patent implements dynamic measurement resource coordination where the UE can flexibly assign different RX beams to different carriers or measurement occasions based on capability indications and network configuration. This dynamic approach optimizes measurement throughput by adapting beam usage to current measurement requirements, thereby reducing measurement time without excessive complexity.
2Productivity
If the UE supports multiple RX beams for measurements on a single carrier, then the measurement throughput and speed improve, but the complexity of coordinating measurement resources increases
Solution Approach 1:
The patent applies preliminary action by having the UE indicate its simultaneous RX beams capability to the network before actual measurements begin. This capability indication allows the network to pre-configure appropriate measurement resources and beam assignments, enabling high measurement throughput while avoiding the complexity of real-time resource coordination during measurements.
Solution Approach 2:
The patent implements feedback mechanisms where the UE provides capability information about its simultaneous RX beams support to the network. This feedback enables the network to make informed decisions about resource allocation and measurement configuration, achieving high measurement productivity without excessive coordination complexity through informed resource management.
3Reliability
If the UE performs L3 and L1 measurements on multiple carriers simultaneously, then the measurement completeness improves, but the measurement period becomes longer due to resource constraints
Solution Approach 1:
The patent resolves the contradiction by adding the beam dimension to the measurement process. Instead of measuring multiple carriers sequentially in time, the UE can perform measurements on multiple carriers simultaneously by using different RX beams for different carriers. This dimensional change from time-sequential to space-parallel measurements achieves both measurement completeness and reduced measurement period.

AI summary
The present disclosure is related to indication of simultaneous RX beams capability and related measurement resource coordination. In an embodiment, a UE is configured to receive, from a base station, a measurement configuration comprising a measurement period for performing measurements on one or more carriers. The UE is further configured to assign measurement resources to the one or more carriers based on a simultaneous RX beams capability, wherein the measurement resources comprise searchers and RX beams during each measurement occasion. The UE is further configured to determine a measurement period scaling factor for the one or more carriers based on the assigned resources. With this capability, the UE can complete L1 and/or L3 measurements and transmit a measurement report to the base station earlier.
