Repeater Measurement Gap Alignment for Accurate Beam Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring measurement gaps for repeater network nodes and user equipment to perform accurate measurements, leading to potential interference and suboptimal performance.
Innovation Solution
A method and apparatus for configuring measurement gaps, where a repeater network node and a transmitter network node coordinate to set overlapping measurement gaps for both the repeater and user equipment, allowing for simultaneous signal transmission and reception during these gaps, with the repeater node transmitting a downlink signal based on received signals during the gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the repeater network node performs measurements during its own measurement gap, then the repeater can adjust its beam, but the measurement gap may not overlap with the UE's measurement gap causing misaligned beam adjustments
Solution Approach 1:
The patent merges the measurement gap configuration of the repeater network node with that of the UE by receiving a measurement gap configuration from the network node that indicates a measurement gap overlapping with the UE's measurement gap. This ensures both entities perform measurements during the same time period, aligning their beam adjustments and preventing handover failures.
Solution Approach 2:
The patent changes the timing parameter of the repeater's measurement gap to overlap with the UE's measurement gap. By adjusting the measurement gap configuration parameters (timing, duration), the system ensures synchronized measurement periods between the repeater and UE, resolving the misalignment issue.
2Productivity
If the repeater network node transmits downlink signals during non-overlapping measurement gaps, then continuous communication is maintained, but beam adjustments become inaccurate due to timing misalignment
Solution Approach 1:
The patent applies preliminary action by configuring the repeater network node to perform measurements during overlapping measurement gaps before transmitting downlink signals. This ensures beam adjustments are made with accurate measurement data, improving beam adjustment accuracy while maintaining communication continuity through proper timing coordination.
3Adaptability or versatility
If separate measurement gaps are used for repeater and UE, then independent measurement operations are possible, but synchronized beam adjustments cannot be achieved
Solution Approach 1:
The patent merges the measurement timing of the repeater and UE by configuring overlapping measurement gaps. While the repeater and UE maintain independent measurement operations, the overlapping timing ensures their beam adjustments are synchronized, resolving the contradiction between independent operation and synchronized adjustment.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater network node may obtain a measurement gap configuration that indicates a measurement gap to be used by the repeater network node for performing a measurement. The repeater network node may receive a downlink signal from a transmitter network node. The repeater network node may transmit the downlink signal, to a user equipment (UE), based at least in part on the downlink signal being received during the measurement gap. Numerous other aspects are described.
