Terminal Device RX RF Chain Segmentation for Intra-Frequency Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications, especially with hybrid beamforming antennas, intra-frequency measurements disrupt ongoing services, causing inefficiencies and poor user experiences as devices must stop current activities to perform measurements, leading to service interruptions during measurement gaps.
Innovation Solution
A terminal device with multiple RX RF chains selects a first set for intra-frequency measurements and a second set for information reception during measurement gaps, allowing simultaneous intra-frequency measurement and data reception by using different RX RF chains for candidate and serving beams respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device uses all RX RF chains for intra-frequency measurement during measurement gap, then measurement precision is improved, but information reception is interrupted and communication efficiency deteriorates
Solution Approach 1:
The patent segments the RX RF chains into two distinct groups: a first set dedicated to intra-frequency measurement and a second set dedicated to information reception. This segmentation allows simultaneous execution of measurement and reception tasks without mutual interference, resolving the contradiction between measurement precision and communication efficiency.
Solution Approach 2:
The terminal device is designed with multiple RX RF chains that can perform multiple functions - some chains are configured for measurement while others maintain data reception. This multi-functionality enables the system to achieve both precise measurement and continuous communication, eliminating the traditional trade-off.
2Reliability
If the terminal device stops ongoing activities to perform intra-frequency measurement, then measurement reliability is improved, but service continuity deteriorates
Solution Approach 1:
By dividing RX RF chains into measurement-dedicated and reception-dedicated sets, the patent enables measurement activities to proceed reliably without forcing termination of ongoing services. The segmented architecture ensures that measurement tasks can be performed with full resource allocation while services continue uninterrupted on separate chains.
Solution Approach 2:
The patent maintains continuous information reception during the measurement gap by allocating a second set of RX RF chains specifically for this purpose. This continuity of useful action ensures that services are not interrupted while measurements are being performed, resolving the contradiction between measurement reliability and service continuity.
3Adaptability or versatility
If the terminal device uses hybrid beamforming antenna with multiple RF chains, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent manages the complexity of hybrid beamforming systems by segmenting the control and configuration of multiple RX RF chains. Through selection rules and configurable parameters, the system can adaptively allocate chains to different functions without requiring complex real-time reconfiguration, thus maintaining adaptability while controlling complexity.

AI summary
Embodiments of the present disclosure relate to methods and devices for information reception during an intra-frequency measurement gap. In example embodiments, the terminal device is served by at least one network device and includes a receiver equipped with a plurality of RX RF chains. The terminal device selects two sets of RX RF chains from the plurality of RX RF chains and uses these two sets of RX RF chains respectively for an intra-frequency measurement and information reception during an intra-frequency measurement gap. In this way, efficiencies of communications/services may be improved, and further user experiences may be improved.
