Uplink Skip Indication for Blind-Detect Reception Energy Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems waste energy due to unnecessary uplink reception by network devices, particularly in semi-static configurations where blind-detect reception occurs.
Innovation Solution
A method for transmitting indication information from a UE to a network device to skip uplink reception of preset channels during specific durations, using configured grant physical uplink shared channels (CG-PUSCH) and physical uplink control channels (PUCCH) to reduce blind-detect reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices perform blind-detect reception for uplink channels, then reception reliability is improved, but energy consumption increases
Solution Approach 1:
The UE performs preliminary action by sending indication information in advance to notify the network device of its absence from the uplink channel. This allows the network device to skip blind-detect reception during the indicated duration, eliminating unnecessary energy consumption while maintaining reception reliability when the UE is actually present.
Solution Approach 2:
The system implements feedback through the indication information sent from UE to network device. The UE provides feedback about its channel usage status, enabling the network device to adjust its reception behavior accordingly - skipping reception when unnecessary and maintaining it when needed, thus resolving the contradiction between reliability and energy consumption.
2Use of energy by stationary object
If network devices skip uplink reception based on indication information, then energy consumption is reduced, but information loss may occur
Solution Approach 1:
The indication information serves as feedback from the UE to the network device about the UE's presence and data transmission status. This feedback mechanism ensures that the network device only skips reception when the UE confirms it will not be transmitting, preventing information loss while reducing energy consumption during skipped periods.
Solution Approach 2:
The UE sends indication information in advance before the duration for which it will be absent from the channel. This preliminary notification allows the network device to confidently skip reception without risk of missing critical information, as the UE has already confirmed its absence in advance.

AI summary
A method for sending indication information includes sending the indication information to a network device, where the indication information is used for indicating the network device to skip, within a first duration, uplink reception of a preset channel.
