Resource Indication Encoding for Multi-Slot Frequency Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in V2X technologies are limited by high signaling overheads when indicating frequency domain resources, which can impact data transmission reliability and efficiency.
Innovation Solution
A method that uses a single value of resource indication information to indicate multiple frequency domain resources, allowing a receiving device to determine the positions of these resources, thereby reducing signaling overheads and ensuring timely data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If resource indication information indicates only one frequency domain resource position, then the signaling format is simple, but the signaling overhead increases when multiple resources need to be indicated
Solution Approach 1:
The patent merges the indication of multiple frequency domain resources into a single resource indication value. Instead of separately indicating each resource position, the invention combines multiple resource positions into one compressed indication value that can represent multiple resources, thereby reducing signaling overhead while maintaining the ability to convey complete resource information.
Solution Approach 2:
The patent changes the parameter representation method by encoding multiple frequency domain resource positions into a single resource indication value. This parameter transformation allows the system to convey information about multiple resources using a compact representation, reducing the signaling overhead associated with indicating each resource separately.
2Measurement precision
If multiple frequency domain resources are indicated using separate resource indication information, then each resource position is clearly specified, but the signaling overhead increases
Solution Approach 1:
The patent combines multiple resource position indications into a single resource indication value that maintains precise information about each frequency domain resource position. This merging approach preserves measurement precision while reducing the total signaling overhead by eliminating redundant indication structures.
3Loss of time
If resource indication information is sent in advance before data transmission slots, then receiving devices can prepare for timely data reception, but the signaling overhead accumulates across multiple slots
Solution Approach 1:
The patent merges resource indications for multiple future slots into a single indication value sent in advance. This allows receiving devices to prepare for timely data reception across multiple slots while reducing the cumulative signaling overhead that would result from sending separate indications for each slot.

AI summary
Embodiments of this application relate to the field of communications technologies, provide a resource indication method, a resource determining method, and an apparatus, to indicate different resources by using a value of same resource indication information, and can be applied to an internet of vehicles, for example, V2X, LTE-V, and V2V; or can be used in fields such as D2D, intelligent driving, and intelligent connected vehicles. The method includes: determining a first resource in a first slot and a second resource in a second slot, where the first resource and the second resource are used to send data; and sending resource indication information in a third slot, where a value of the resource indication information is used to indicate a frequency domain position of the first resource and a frequency domain position of the second resource, and the second slot and the first slot are later than the third slot. In this way, a value of one piece of resource indication information can be used to indicate two different resources.
