Unified Uplink Grant for Concurrent Voice and Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power saving approaches in wireless communication devices, such as discontinuous reception (DRX) and discontinuous transmission (DTX), are ineffective when devices transmit data of disparate profiles like voice data and web traffic, leading to suboptimal battery life and user experience.
Innovation Solution
The system aligns the transmission of non-voice data with the semi-persistent scheduling (SPS) uplink timing for voice data, allowing the RF modem and transceiver to be turned off during non-transceiving periods, thereby optimizing battery life by maintaining power savings even during simultaneous transmission of distinct data profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional power saving approaches (DRX/DTX) are used for voice data transmission, then power consumption is reduced during idle periods, but the transmitter must remain active for non-voice data transmission, causing increased power consumption
Solution Approach 1:
The patent combines voice data transmission and non-voice data transmission into a single unified transmission mechanism. By using one uplink grant to schedule both types of data on the same uplink channel, the system merges what would otherwise require separate transmission resources, allowing the transmitter to be activated for a single purpose rather than requiring separate activation for each data type.
Solution Approach 2:
The uplink grant mechanism is designed to be universal, capable of scheduling both voice data and non-voice data through a single allocation. This multi-functional approach allows the same transmission resource to serve multiple data types, eliminating the need for separate transmission channels and reducing overall power consumption while maintaining versatility.
2Productivity
If the transmitter is kept active for non-voice data transmission, then data transmission capability is maintained, but battery life is reduced
Solution Approach 1:
The patent combines voice data transmission and non-voice data transmission into a single unified transmission mechanism. By using one uplink grant to schedule both types of data on the same uplink channel, the system merges what would otherwise require separate transmission resources, allowing the transmitter to be activated for a single purpose rather than requiring separate activation for each data type.
Solution Approach 2:
The system maintains continuous transmission capability for both voice and non-voice data through a unified scheduling mechanism. By ensuring that both data types can be transmitted within the same activation period, the system maintains productivity without requiring repeated transmitter activations, thereby extending battery life while preserving continuous data transmission capability.
3Reliability
If separate transmission resources are allocated for voice and non-voice data, then each data type can be transmitted independently, but device complexity increases
Solution Approach 1:
The patent combines voice data transmission and non-voice data transmission into a single unified transmission mechanism. By using one uplink grant to schedule both types of data on the same uplink channel, the system merges what would otherwise require separate transmission resources, allowing the transmitter to be activated for a single purpose rather than requiring separate activation for each data type.
Solution Approach 2:
While using a unified transmission mechanism, the patent segments different data types within the same transmission resource. By allocating specific portions or time slots within the uplink grant for different data types, the system maintains independent transmission capability for voice and non-voice data while reducing overall device complexity compared to fully separate resource allocation.

AI summary
Systems and approaches are provided to reduce power usage of a computing device connected to a third generation (3G), 3G+, or fourth generation (4G) mobile network. A computing device can be configured for concurrent transmission of a first type of data, such as VoIP or VoLTE data, and a second type of data, such as web traffic or file download data, yet remain optimized for low power usage. The quality of service (Qos) for VoIP or VoLTE is not affected by these systems and techniques while changes to the computing device's data throughput capacity can be minimized for transmission of the second type of data. These techniques can be directed or managed by the computing device or the network in various embodiments.
