EDT Transmission Block Size Determination for UE Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication protocols, the lack of a scheme for determining the transmission block size (TBS) during early data transmission (EDT) prevents efficient resource allocation for user equipment (UE) data transmission to a base station.
Innovation Solution
A method and device that enable a terminal to determine the TBS supported by the data transmission based on indication information, allowing the base station to allocate resources effectively for EDT by using pre-configured TBS sets and rules to identify the maximum and other relevant TBS values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If downlink control information is transmitted using existing resources without reservation, then spectrum utilization is improved, but collision between control information and data information occurs
Solution Approach 1:
The patent applies preliminary action by having the terminal device send a first signal before the downlink control information transmission time to reserve the time-frequency resource. This reservation mechanism prevents collisions between control information and data information while still allowing efficient spectrum utilization. The gNodeB uses this reservation signal to allocate resources in advance, ensuring control information is transmitted without interference.
2Reliability
If time-frequency resource is reserved for downlink control information, then transmission reliability is improved, but spectrum utilization efficiency decreases
Solution Approach 1:
The patent applies dynamics by making the resource reservation flexible rather than fixed. The terminal device sends a first signal to reserve resources, but the actual resource allocation is dynamically adjusted based on real-time communication needs. This dynamic reservation mechanism ensures reliability when needed while maintaining high spectrum utilization efficiency when conditions allow, avoiding wasted reservation resources.
3Device complexity
If existing resource allocation methods are used for downlink control information, then device complexity is reduced, but collision with data information occurs
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of a first signal exchanged between terminal devices and gNodeB. This intermediary reservation signal acts as a mediator that coordinates resource allocation without requiring complex centralized control. The first signal simplifies the allocation process while preventing collisions between control and data information transmission, maintaining system reliability with minimal added complexity.
