Dynamic Slot Allocation for Voice Traffic in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems do not differentiate between voice traffic and other traffic, leading to inadequate configuration and quality for voice communications, as they use common slots for both, resulting in suboptimal resource allocation.
Innovation Solution
The method involves obtaining slot allocation information from a network device to configure separate slots for voice traffic and other traffic, allowing for dynamic resource allocation by designating specific slots for voice communication and others for non-voice communication, with varying ranks and modulation and coding schemes to optimize voice quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If common slots are used for both voice traffic and other traffic, then resource allocation is simplified, but voice quality deteriorates due to inadequate configuration
Solution Approach 1:
The patent segments the time-frequency resources by introducing separate slot types: voice slots specifically configured for voice traffic and non-voice slots for other traffic. This segmentation allows voice traffic to receive dedicated resources with appropriate configuration parameters (such as lower modulation and coding schemes), thereby improving voice quality without requiring complex overall resource allocation management.
2Reliability
If separate slots are allocated for voice traffic and other traffic, then voice quality is improved through dedicated resources, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation where the network can flexibly configure and switch between voice slots and non-voice slots based on real-time traffic conditions. This dynamic approach allows the system to maintain separate slot configurations for voice quality assurance while adapting resource distribution to actual needs, preventing excessive complexity from rigid static allocation.
3Ease of operation
If common slots are used for all traffic, then resource allocation is straightforward, but packet loss and fast fading occur due to suboptimal configuration
Solution Approach 1:
The patent applies local quality optimization by configuring voice slots with specific parameters tailored for voice traffic characteristics (such as lower modulation and coding schemes suitable for real-time communication). This localized configuration ensures that voice traffic receives optimal protection against packet loss and fast fading, while other slots can use different configurations for their respective traffic types.

AI summary
Provided is a method for a user equipment (UE). The UE obtains a slot allocation information from a network device. The slot allocation information indicates a first slot and a second slot. The first slot is configured to communicate voice traffic and the second slot is configured to communicate traffic other than voice. The UE communicates the voice traffic in the first slot and the traffic other than voice in the second slot.
