Network-Controlled Repeater Beam Management via Resource Set Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The beam management for network-controlled repeaters is undefined, necessitating the development of effective methods to optimize link measurements and management.
Innovation Solution
The solution involves configuring distinct resource sets for measuring different links between a repeater device and a terminal device, and between a network device and a terminal device. Control information is transmitted to the repeater device to turn it on or off based on reference signal transmissions on these resource sets, allowing for accurate link measurements and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the repeater device continuously forwards reference signals for link measurements, then measurement coverage is improved, but measurement precision deteriorates due to noise amplification
Solution Approach 1:
The repeater device is controlled to periodically turn on and off based on control information from the network device. During 'on' periods, the repeater forwards reference signals for link measurements. During 'off' periods, the repeater remains silent, allowing direct measurements between the network device and terminal device without repeater interference. This periodic operation enables the system to distinguish between direct links and repeater-assisted links, resolving the contradiction between continuous measurement coverage and measurement precision.
2Area of stationary object
If the repeater device amplifies all received signals, then coverage extension is improved, but signal quality deteriorates due to unnecessary noise amplification
Solution Approach 1:
The repeater device transitions from a static continuous amplification mode to a dynamic conditional amplification mode. Based on control information received from the network device, the repeater dynamically adjusts its operation state (on/off) and amplification behavior. This allows the system to extend coverage when needed while avoiding noise amplification during direct communication periods, thus resolving the contradiction between coverage extension and signal quality.
3Reliability
If beam management is implemented for network-controlled repeaters, then communication performance is improved, but system complexity increases due to undefined beam management procedures
Solution Approach 1:
The beam management procedure is segmented into distinct phases and components: network device beam management, repeater beam management, and terminal device beam management. Each phase has clearly defined control information formats and operational procedures. The first resource set is configured for measuring the first link (repeater to terminal), while the second resource set is configured for measuring the second link (network device to terminal). This segmentation reduces the overall complexity by breaking down the undefined beam management into manageable, standardized segments.

AI summary
Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. In response to transmitting a first reference signal on a resource in a first resource set, a network device transmits, to a repeater device, first control information indicating turn-on of the repeater device, the first resource set being configured for a first measurement of a first link between the repeater device and a terminal device. In response to transmitting a second reference signal on a resource in a second resource set, the network device transmits, to the repeater device, second control information indicating turn-off of the repeater device, the second resource set being configured for a second measurement of a second link between the network device and the terminal device, the first resource set being different from the second resource set. In this way, beam management for a network-controlled repeater device can be achieved.
