Indication-Based Scheduling Data Reception for Lower Terminal Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE and NR communication services, the frequent demodulation of physical downlink control channels (PDCCH) for non-control channel scheduling data leads to high power consumption and unnecessary data reception due to mismatched service periods and small data periods, resulting in the acquisition of useless data.
Innovation Solution
A method and apparatus for transmitting non-control channel scheduling data using indication information, where a terminal determines whether to receive scheduling data based on indication information before the scheduled moment, reducing unnecessary data reception and power consumption by using digital sequences to indicate whether to receive or skip data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the terminal frequently demodulates PDCCH to receive scheduling data, then the data reception timeliness is improved, but the power consumption increases
Solution Approach 1:
The base station sends indication information in advance before the terminal needs to receive scheduling data. This indication information tells the terminal whether scheduling data will be transmitted at a specific time, allowing the terminal to prepare accordingly and avoid unnecessary demodulation operations, thus reducing power consumption while maintaining timely data reception when needed
Solution Approach 2:
The terminal uses the received indication information to autonomously determine whether to perform demodulation of the physical downlink shared channel (PDSCH). This self-service mechanism allows the terminal to independently optimize its power consumption by skipping demodulation when the indication shows no data is available, without requiring continuous network control
2Reliability
If the terminal receives scheduling data at every preset moment, then the data availability is improved, but useless data is received increasing power consumption
Solution Approach 1:
The indication information extracts and conveys only the essential scheduling status (whether data is available or not) to the terminal. This extracted information allows the terminal to selectively receive only useful scheduling data while ignoring moments when no data is available, thereby maintaining data availability when needed while avoiding energy waste from receiving useless data
3Speed
If the terminal always monitors for scheduling data, then the scheduling responsiveness is improved, but the power consumption increases
Solution Approach 1:
The base station performs preliminary action by sending indication information in advance that tells the terminal whether scheduling data will be available. This allows the terminal to maintain high scheduling responsiveness by quickly acting on the indication when data is available, while avoiding continuous monitoring and reducing power consumption by staying in a lower-power state when no data is expected

AI summary
A method for transmitting non-control channel scheduling data based on indication information includes determining whether the indication information is received before a preset moment of receiving the non-control channel scheduling data. The indication information is configured to indicate parameters of a terminal related to reception of the non-control channel scheduling data. Another method for transmitting non-control channel scheduling data based on indication information includes determining whether to send the indication information to a terminal before a preset moment of sending the non-control channel scheduling data, wherein the indication information is configured to indicate parameters of the terminal related to reception of the non-control channel scheduling data.
