UE Measurement Reporting with Adaptive Beam Indicator Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in reducing measurement report overhead while ensuring sufficient information is provided to the network entity, particularly when UE conditions change.
Innovation Solution
The UE dynamically adjusts the periodicity and indicator size of measurement reports based on reporting metrics, such as RSRP values, to optimize reporting frequency and reduce redundant information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement reports are transmitted with configured periodicity and indicator size, then sufficient information is provided to the network entity, but overhead increases
Solution Approach 1:
The patent applies dynamics by making the measurement report periodicity and indicator size adjustable rather than fixed. The UE dynamically adapts the reporting periodicity based on beam failure detection and recovery status, and adjusts indicator size based on the number of candidate beams, thereby optimizing the balance between information sufficiency and overhead reduction
Solution Approach 2:
The patent implements parameter changes by modifying the reporting periodicity and indicator size parameters based on channel conditions and beam status. When beam failure is detected, the periodicity is adjusted to ensure timely reporting, and the indicator size is adapted based on the number of candidate beams available, achieving overhead reduction while maintaining necessary information quality
2Reliability
If measurement reports are transmitted frequently, then network entity receives timely information, but power consumption increases
Solution Approach 1:
The patent applies dynamics by adjusting the reporting periodicity based on beam failure detection and recovery status. When beam failure is detected, the UE transitions to a second periodicity that may differ from the configured first periodicity, enabling timely information delivery during critical events while reducing power consumption during stable conditions
Solution Approach 2:
The patent implements periodic action with variable periodicity. The UE transmits measurement reports at configured periodic intervals under normal conditions, but dynamically adjusts the periodicity when beam failure is detected or during recovery processes, achieving timely information delivery only when necessary while reducing power consumption during stable operation
3Quantity of substance
If indicator size is reduced to minimize overhead, then overhead decreases, but reporting precision may be insufficient
Solution Approach 1:
The patent implements parameter changes by adapting the indicator size based on the number of candidate beams. When the number of candidate beams is small, a smaller indicator size suffices, reducing overhead. When more beams are available, the indicator size is increased to maintain adequate precision for beam identification
Solution Approach 2:
The patent applies local quality by making the indicator size variable rather than uniform. Different indicator sizes are used depending on the local condition of candidate beam quantity, ensuring sufficient precision is provided only where needed while reducing overhead in situations with fewer beams

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a set of measurement report occasions for transmission of measurement reports associated with a first periodicity between measurement report occasions, the measurement reports associated with a first indicator size for reporting indicators of beams. The UE may measure reference signals associated with the measurement reports to determine potential beams for communications with the network entity. The UE may transmit a measurement report including one or more indicators, each indicator indicating one of the potential beams, and each indicator may have a second indicator size smaller than the first indicator size based on the quantity of the potential beams. Further, the UE may transmit measurement reports with a second periodicity different from the first periodicity based on a reporting metric being within a first value range of a set of value ranges.
