Joint Coding for Reference Signal Resource Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for indicating whether tracking reference signal (TRS) or channel state information-reference signal (CSI-RS) resources are effective for a terminal in an idle or inactive state are inefficient, often requiring excessive signaling resources and complex indication mechanisms.
Innovation Solution
The implementation of joint coding methods by a base station to determine and indicate the availability of in-effect reference signal resources, using coding values that reduce signaling overhead and improve indication efficiency, allowing terminals to quickly determine the availability of these resources.

1Quantity of substance
If traditional separate indication methods are used for in-effect reference signal resources and beam availability, then indication completeness is maintained, but signaling resource overhead increases and indication efficiency decreases
Solution Approach 1:
The patent combines the indication of in-effect reference signal resources and beam availability into a single joint coding value. Instead of using separate indication mechanisms, the system encodes both pieces of information together, reducing signaling overhead while maintaining complete information transmission. The joint coding value simultaneously indicates whether reference signal resources are in-effect and their availability to specific beams.
Solution Approach 2:
The joint coding value serves multiple functions simultaneously: it indicates both the in-effect status of reference signal resources and the availability of these resources to different beams. This multi-functional encoding approach eliminates the need for separate indication signals, reducing resource consumption while maintaining comprehensive information conveyance.
2Device complexity
If detailed separate indication mechanisms are used for reference signal resource status and beam availability, then information completeness is maintained, but indication complexity increases
Solution Approach 1:
The patent merges multiple indication functions into a single joint coding value, reducing the complexity of the indication mechanism. By combining the in-effect status indication and beam availability indication into one encoded value, the system maintains information completeness while significantly simplifying the overall indication structure and processing requirements.
3Productivity
If traditional indication methods are used for idle or inactive state terminals, then compatibility with existing systems is maintained, but signaling efficiency decreases
Solution Approach 1:
The patent changes the encoding parameter from separate indication bits to a unified joint coding value. This parameter transformation enables more efficient signaling for idle or inactive state terminals by reducing the number of bits required while maintaining all necessary information, thereby improving signaling efficiency without increasing mechanism complexity.

AI summary
Provided are methods and devices for joint coding and determining in-effect reference signal resources. The method for joint coding comprises: determining a first coding value by joint coding on a first indication information, wherein the first indication information is used for indicating in-effect reference signal resources and whether the in-effect reference signal resources are available or unavailable to at least one first beam; and sending the first coding value. By means of joint coding, signaling resource overhead is reduced, and indication efficiency of in-effect reference signal resources and whether the in-effect reference signal resources are available to a beam are improved. In particular, when in-effect reference signal resources are all available to at least one first beam, sending a bitmap used for indicating whether the in-effect reference signal resources are available to each first beam can be avoided, and resource overhead can be further lowered.
