Terminal Aperiodic CSI-RS Reception Timing Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminals face challenges in efficiently receiving downlink signals without buffering, particularly in managing the timing of signal reception to optimize power usage and processing efficiency.
Innovation Solution
A method is introduced where the terminal receives information about a time period with no buffering for downlink signal reception, allowing it to preconfigure this period and thereby stabilize the processing of the physical downlink control channel, reducing the power required for signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously buffers downlink signals for reception, then the reliability of signal reception is improved, but the power consumption increases
Solution Approach 1:
The terminal performs discontinuous buffering of downlink signals by configuring a specific time period during which buffering is not performed. This periodic action allows the terminal to maintain signal reception reliability during configured buffering periods while reducing power consumption by stopping buffering operations during non-buffering periods, directly resolving the contradiction between continuous buffering reliability and power efficiency
2Stability of the object's composition
If the terminal processes the physical downlink control channel continuously, then the processing stability is improved, but the power consumption increases
Solution Approach 1:
The terminal configures a time period during which buffering is not performed, creating periodic intervals for control channel processing. This ensures processing stability is maintained during configured periods while power consumption is reduced during intervals when buffering is suspended, resolving the contradiction between continuous processing stability and power efficiency

AI summary
Disclosed is a method for a terminal to receive a downlink signal from a base station in a wireless communication system. Specifically, the present invention may include: a step for acquiring a minimum CSI-RS triggering offset that is applicable to a CSI-RS for aperiodic CSI on the basis of the reception of a minimum applicable slot interval for the scheduling of a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH); a step for receiving, from the base station, downlink control information (DCI) for triggering the aperiodic CSI in a first slot; and a step for receiving the CSI-RS from the base station at a point in time later than the first slot and a second slot that is set on the basis of a CSI-RS triggering offset larger than or equal to the minimum applicable CSI-RS triggering offset.
