Reference Timing Configuration for Wireless Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in determining a reference timing for discovery procedures, particularly in scenarios where synchronization signals like PSS and SSS are not available initially, leading to potential communication errors due to timing offsets and inter-symbol interference.
Innovation Solution
The method involves determining a reference timing for wireless communication devices using either a receive timing from a host device, an internal timing, or a combination of both, to configure a synchronized timing for transmitting responses to discovery signals, thereby reducing timing offsets and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discovery signals are transmitted without available synchronization signals (PSS/SSS), then device discovery can be enabled in new radio access technologies, but timing offsets and inter-symbol interference occur causing communication errors
Solution Approach 1:
The patent introduces a reference signal as an intermediary element that provides timing information without requiring traditional synchronization signals. This reference signal acts as a mediator between the discovering device and the discovered device, enabling time alignment for discovery signals even when PSS/SSS are unavailable, thus resolving the contradiction between enabling device discovery and maintaining communication accuracy
Solution Approach 2:
The patent performs preliminary timing alignment by configuring a reference timing before the actual discovery signal transmission. This preliminary action establishes a common time reference for both devices, preventing timing offsets and inter-symbol interference during the subsequent discovery procedure, thereby enabling reliable communication without traditional synchronization signals
2Reliability
If larger cyclic prefixes and gaps are used to accommodate timing uncertainties, then communication reliability may be maintained, but bandwidth utilization and resource efficiency decrease
Solution Approach 1:
The patent replaces the mechanical approach of using larger cyclic prefixes and gaps to accommodate timing uncertainties with a more precise timing configuration system. By establishing a reference timing that enables accurate time alignment, the system eliminates the need for excessive timing margins, thereby improving bandwidth utilization while maintaining communication reliability through precise rather than conservative timing approaches

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.
