Wireless Reference Signal Scheduling Ambiguity Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, there is a risk of confusion when User Equipment (UE) is scheduled to measure or transmit reference signals across multiple reference signal resources, particularly with the repeated scheduling of aperiodic reference signals, which can lead to misunderstandings about the specific reference signals involved.
Innovation Solution
A method where a UE receives two signalings, with the first signaling containing a first field and the second signaling containing a second field, both used jointly to determine if a radio signal is related to the first signaling, thereby avoiding confusion by explicitly scheduling and identifying the relevant reference signals, and utilizing multi-antenna related processing to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aperiodic reference signals are scheduled repeatedly to support diverse 5G features, then channel status information acquisition and beam scanning capabilities are improved, but confusion arises when UE must measure or transmit reference signals in multiple reference signal resources
Solution Approach 1:
The patent segments the reference signal identification process into two distinct fields: a first field in the first signaling for initial reference signal resource indication, and a second field in the second signaling for confirming or updating the reference signal identification. This segmentation allows the system to maintain adaptability for diverse 5G features while preventing confusion through structured, multi-stage identification.
Solution Approach 2:
The patent introduces an intermediary mechanism where the first signaling with the first field acts as an initial indicator, and the second signaling with the second field serves as a confirming or updating indicator. This intermediary approach resolves the contradiction by providing a structured two-stage identification process that maintains both versatility and accuracy.
2Quantity of substance
If multiple reference signals are scheduled for transmission or measurement, then comprehensive channel information is obtained, but misunderstanding about which reference signal is related to which radio signal occurs
Solution Approach 1:
The patent applies segmentation by dividing the association information into two parts: the first field identifies the reference signal resource in the first signaling, and the second field provides additional identification or confirmation in the second signaling. This allows multiple reference signals to be scheduled while maintaining clear association information for each radio signal.
Solution Approach 2:
The patent implements preliminary action by first providing the first field in the first signaling to establish initial reference signal identification, then using the second field in the second signaling to confirm or update the association. This preliminary identification followed by confirmation prevents misunderstanding about reference signal associations.
3Device complexity
If reference signals are scheduled without explicit identification fields, then signaling overhead is reduced, but confusion about reference signal resources cannot be avoided
Solution Approach 1:
The patent segments the identification information into two separate fields across two signalings rather than using a single complex identification mechanism. This segmentation provides reliable reference signal scheduling while keeping the signaling structure manageable through distributed information provision.
Solution Approach 2:
The patent uses preliminary action by first providing reference signal identification information in the first field of the first signaling, then reinforcing or updating this information in the second field of the second signaling. This two-stage approach ensures reliable scheduling without requiring overly complex single-stage signaling.

AI summary
The present disclosure provides a method and a device for wireless communication. The UE receives a first signaling and a second signaling from a base station, and then operates a first radio signal. Herein, the first signaling comprises a first field, the second signaling comprises a second field; the second signaling comprises first-type scheduling information of the first radio signal; the first field of the first signaling and the second field of the second signaling are jointly used for determining whether the first radio signal is related to the first signaling; the operating action is receiving, or the operating action is transmitting. When the UE is scheduled to transmit or measure a plurality of reference signals, the above method can be employed to avoid possible misunderstanding or confusion resulted from citation of one reference signal.
