Grouped WUR Wake-Up Packets for Lower Wireless Network Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for waking up multiple WUR terminals in a wireless network consume significant air interface time and resources, leading to increased network overheads due to the need to send wake-up packets sequentially to each terminal.
Innovation Solution
A method and apparatus that groups WUR terminals based on predefined criteria, assigns group identifiers, and sends a single wake-up packet to wake up all terminals in a group, reducing the number of individual wake-up packets required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wake-up packets are sent sequentially to each WUR terminal, then each terminal can be reliably woken up, but air interface time and radio access point resources are consumed excessively
Solution Approach 1:
The patent merges multiple individual wake-up packets into a single group wake-up packet that can wake up multiple WUR terminals simultaneously. The group wake-up packet contains a group identifier that matches terminals belonging to that group, allowing one packet to serve multiple terminals and thereby reducing air interface time and resource consumption while maintaining reliable wake-up functionality.
2Reliability
If wake-up packets are sent sequentially to each WUR terminal, then each terminal receives individual attention, but network overheads are increased
Solution Approach 1:
The patent combines multiple individual wake-up packets into a single group wake-up packet structure. This merging reduces the total number of packets transmitted over the network, thereby reducing network overheads. The group wake-up packet contains essential information including group identifier and terminal identifiers, maintaining the necessary information for reliable wake-up while minimizing redundant data transmission.
3Measurement precision
If individual wake-up packets are sent to each WUR terminal, then precise terminal identification is achieved, but radio access point resources are consumed excessively
Solution Approach 1:
The patent merges multiple individual wake-up operations into a single group wake-up operation. The group wake-up packet contains a group identifier and multiple terminal identifiers, allowing the radio access point to identify and wake up multiple terminals in one operation. This approach maintains precise terminal identification capability while significantly reducing radio access point resource consumption compared to sending separate packets to each terminal.

AI summary
A method and an apparatus for waking up a WUR terminal in a wireless network are disclosed. The method includes: A radio access point groups at least one WUR terminal into at least one group according to a grouping rule; allocates a group identifier to each of the at least one group; sends a corresponding group identifier to each of the at least one WUR terminal; and sends a WUR wake-up packet including a group identifier of a target group, to attempt to wake up all WUR terminals in the target group. The WUR terminal includes a main radio frequency circuit and a WUR radio frequency circuit, where the main radio frequency circuit receives a group identifier of a group to which the WUR terminal belongs; and sends the group identifier of the group to which the WUR terminal belongs to the WUR radio frequency circuit; and the WUR radio frequency circuit receives the wake-up packet, where the wake-up packet includes the group identifier of the target group; and wakes up the WUR terminal when the group identifier of the target group is the group identifier of the group to which the WUR terminal belongs. Air interface time and resource consumption of the radio access point can be reduced, and network overheads are reduced.
