Pre-Configured Transmission Occasions for Varying-Size Mobile Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to efficiently utilize configured grants (CG resources) for the transmission of varying sized data in mobile communications, particularly for applications like extended reality (XR) and augmented reality (AR), due to the unpredictable frame sizes of time-sensitive media data.
Innovation Solution
A UE receives a configuration from a network for a set of CG resources and indicates the number of used or unused resources to the network, allowing flexible allocation and repurposing of unused resources to other UEs, enhancing resource usage efficiency and performance.

Engineering Contradiction Analysis
1Productivity
If configured grants (CG resources) are used for periodic traffics with known data sizes, then transmission efficiency is improved, but the system cannot handle varying sized data effectively
Solution Approach 1:
The patent applies dynamics by making the CG resource allocation flexible rather than fixed. The network can dynamically adjust the number of CG resources allocated to a UE based on the actual data size to be transmitted. The UE indicates the data size to the network, which then configures the appropriate number of CG resources, allowing the system to adapt to varying data sizes while maintaining efficient configured grant transmission.
2Speed
If CG resources are allocated for each transmission occasion, then transmission speed is improved, but resource utilization efficiency deteriorates when data size is smaller than allocated resources
Solution Approach 1:
The patent changes the parameter of resource allocation from fixed to variable. Instead of allocating a fixed number of CG resources regardless of data size, the system now allocates resources based on the actual data size. The UE reports the data size, and the network adjusts the number of CG resources accordingly, ensuring that resources match the transmission needs and avoiding waste of allocated resources.
Solution Approach 2:
The patent implements feedback by having the UE report the data size to the network before transmission. This feedback loop allows the network to make informed decisions about resource allocation, adjusting the number of CG resources based on the actual transmission needs, thereby improving both transmission speed and resource utilization efficiency.
3Device complexity
If fixed number of CG resources are allocated, then resource management is simplified, but flexibility to adjust to different data sizes is reduced
Solution Approach 1:
The patent applies preliminary action by having the UE report the data size to the network before the actual transmission occurs. This advance information allows the network to pre-configure the appropriate number of CG resources, simplifying the management process while enabling flexible adaptation to different data sizes. The resource allocation decision is made in advance based on reported data characteristics.

AI summary
Techniques and solutions pertaining to using pre-configured transmission occasions in transmission of varying sized data in mobile communications are described. An apparatus (e.g., user equipment (UE)) receives a configuration from a network configuring a set of CG resources. The apparatus transmits an indication to the network indicating a number of CG resources of the set of CG resources used (or unused) in transmission in an occasion.
