Conditional Uplink PUSCH Resource Selection for Lower Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In two-step random access technology, configuring physical uplink shared channel (PUSCH) resources is inefficient, leading to increased load on system information and power consumption in terminals.
Innovation Solution
A method where a terminal determines whether a preset condition is met to select between first and second PUSCH resource configurations based on received system information, reducing unnecessary information reception and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal receives all system information including second PUSCH resource configuration, then the terminal can have more PUSCH resource configuration options, but the system information load and power consumption increase
Solution Approach 1:
The patent extracts the second PUSCH resource configuration from the general system information and separates it into a conditional component. The terminal only receives and processes the second PUSCH resource configuration when specific conditions are met (e.g., when the first PUSCH resource configuration is insufficient or when particular uplink transmission requirements arise). This extraction principle reduces the default system information load while maintaining configuration flexibility when needed.
Solution Approach 2:
The patent implements dynamic system information reception based on terminal conditions. The terminal dynamically determines whether to receive the second PUSCH resource configuration by evaluating preset conditions such as buffer status, channel conditions, or transmission requirements. This dynamic approach allows the system information load to adapt to actual needs, reducing unnecessary information reception and power consumption while maintaining adaptability when required.

3Reliability
If the first system information contains all PUSCH resource configurations, then the configuration is complete, but the system information load increases
Solution Approach 1:
The patent segments the PUSCH resource configuration into two distinct parts: the first PUSCH resource configuration contained in the first system information, and the second PUSCH resource configuration contained in the second system information. This segmentation allows the first system information to remain compact and efficient, while the second configuration provides additional options when needed. The segmentation maintains configuration completeness by ensuring that both parts together cover all possible scenarios.
Solution Approach 2:
The patent implements preliminary action by providing the first PUSCH resource configuration in advance through the first system information. This initial configuration is sufficient for common scenarios, allowing terminals to operate without receiving additional system information. The second PUSCH resource configuration is prepared as a supplementary resource to be activated only when specific conditions require extended configuration options, thereby reducing overall system information load while maintaining completeness.

AI summary
An uplink transmission resource determining method includes: receiving first system information sent by a network device, where the first system information includes a first physical uplink shared channel (PUSCH) resource configuration; determining whether a preset condition is met; receiving second system information sent by the network device when the preset condition is not met, where the second system information includes a second PUSCH resource configuration; and determining, based on the second PUSCH resource configuration, a parameter used for uplink transmission. In this way, a terminal may flexibly select the PUSCH resource configuration in the first system information or the PUSCH resource configuration in the second system information based on a requirement of the terminal. The second system information is received only when the preset condition is not met, to reduce information obtained by the terminal and reduce power consumption of the terminal.
