Pre-Configured Uplink Resource Validation for Low-Signal IoT UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently validating pre-configured uplink resources (PUR) for user equipment (UE) in next-generation networks, particularly for IoT devices with small data transmissions, leading to increased signaling and energy consumption.
Innovation Solution
A validation procedure is introduced for PUR occasions, involving timing advance (TA) validation and PUR validation, ensuring that UE capabilities are considered, and a defined time window is used to perform these validations before uplink transmissions, thereby optimizing resource usage and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs establish a connection before transmitting uplink data, then transmission reliability is improved, but signaling overhead and energy consumption increase
Solution Approach 1:
The system performs validation procedures (timing advance validation and PUR validation) in advance before the actual uplink transmission. The UE validates whether it can use the pre-configured uplink resource before transmitting data, and the network validates the UE's eligibility. This preliminary validation ensures transmission reliability is maintained while avoiding the need for full connection establishment, thereby reducing energy consumption.
2Reliability
If UEs establish a connection before transmitting uplink data, then transmission reliability is improved, but signaling overhead increases
Solution Approach 1:
The validation procedures are performed in advance using minimal signaling. The network provides validation configuration information to the UE, and the UE performs self-validation based on this configuration. Only essential validation results are signaled back to the network, avoiding the need for extensive connection establishment signaling while maintaining transmission reliability.
3Reliability
If validation procedures are performed for every PUR occasion, then transmission reliability is improved, but processing time and energy consumption increase
Solution Approach 1:
The UE performs validation procedures selectively rather than for every PUR occasion. The validation configuration information includes parameters that allow the UE to determine when validation is necessary based on current conditions. This partial validation approach maintains reliability for critical transmissions while reducing processing time and energy consumption for routine operations.

AI summary
Aspects relate to validating a pre-configured uplink resource (PUR) occasion. For example, prior to using a PUR occasion for an uplink transmission, a user equipment (UE) may perform a validation procedure for the PUR occasion. A validation procedure for a PUR occasion may involve ensuring that the UE will be able to reliably transmit during the PUR occasion. A base station may send a PUR configuration to the UE that the UE can use for the validation procedure. The PUR configuration may include timing advance (TA) validation information and PUR validation information that depend on at least on capability of the UE.
