Dynamic UPSS Configuration for Flexible Terminal Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication technologies lack flexibility in the use of user power saving signals (UPSS) by terminals, as they are always in a state of power saving mode, which limits their operational flexibility.
Innovation Solution
A communication method where a network device sends configuration information to a terminal to activate UPSS, allowing the terminal to determine whether to monitor or receive specific channels based on received indication information, improving flexibility in power saving mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the terminal always uses the power saving mechanism (UPSS), then power consumption is reduced, but operational flexibility is limited
Solution Approach 1:
The patent implements dynamic switching between power saving mode and normal operation mode based on terminal state. The network device configures different UPSS parameters (drx-OnDuration, drx-InactivityTimer, etc.) that can be activated or deactivated dynamically through RRC signaling, allowing the terminal to adapt its power consumption characteristics to current operational requirements rather than being locked into a fixed power saving state
Solution Approach 2:
The patent changes key parameters of the power saving mechanism including drx-CycleLength, drx-OnDuration, and drx-InactivityTimer to create multiple configurable power saving modes. By modifying these parameters, the system can adjust the degree of power saving applied, enabling a spectrum from aggressive power saving to minimal power saving rather than a binary choice
2Reliability
If the terminal monitors PDCCH continuously, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of PDCCH through DRX (Discontinuous Reception) cycles. Instead of continuous monitoring, the terminal monitors PDCCH only during configured on-duration windows within each DRX cycle, then enters sleep mode. This periodic action maintains communication reliability by ensuring the terminal checks for incoming data at regular intervals while dramatically reducing power consumption during non-monitoring periods
Solution Approach 2:
The network device performs preliminary configuration of DRX parameters and sends indication information in advance to guide terminal behavior. By pre-configuring the monitoring schedule and sending wake-up indicators before actual data transmission, the system ensures the terminal is ready to receive data when needed while avoiding unnecessary monitoring activity
3Loss of energy
If the terminal enters sleep state frequently, then power consumption is reduced, but response time to incoming data increases
Solution Approach 1:
The network device sends wake-up indication information to the terminal before actual data transmission occurs. This preliminary action wakes the terminal from sleep state in advance, allowing it to transition to active state and prepare for data reception without missing incoming data. The indication is sent during a previous DRX cycle, giving the terminal sufficient notice to respond timely
Solution Approach 2:
The system dynamically adjusts DRX cycle length and on-duration timing based on traffic patterns and terminal state. For time-sensitive applications, the network can configure shorter DRX cycles or extend on-duration periods, dynamically balancing power saving against response time requirements rather than using fixed sleep schedules

AI summary
A communication method includes: when a network device meets an enabling condition, sending, by the network device, configuration information to a terminal, where the configuration information includes at least one of a type of indication information, a form of the indication information, or a receiving location of the indication information; and sending the indication information to the terminal, where the indication information is used to indicate the terminal whether to monitor a physical downlink control channel PDCCH, or indicate the terminal to monitor a PDCCH, or indicate the terminal not to monitor a PDCCH; or the indication information is used to indicate the terminal whether to receive a physical downlink shared channel PDSCH, or indicate the terminal to receive a PDSCH, or indicate the terminal not to receive a PDSCH. This improves flexibility of using the indication information (for example, a UPSS) by the terminal.
