Solution Overview
Problem
Existing communication devices face challenges in managing power consumption and Quality of Service (QoS) due to fixed communication periods, which can lead to incomplete signal transmission and increased power usage when waiting for signal allocation, especially in varying propagation environments.
Innovation Solution
A communication device with a receiver, transmitter, and interruption module that allocates a first period for signal transmission and a second period for potential retransmission, allowing power-saving mode operation by interrupting power supply when transmission is complete or not needed, and using omnidirectional or directional radio waves for efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the access point dynamically allocates the communication period to each terminal, then QoS requirements can be satisfied, but power consumption increases due to waiting for signal allocation
Solution Approach 1:
The patent implements dynamic communication period allocation where the access point assigns different time periods (first period, second period, third period) to terminals based on real-time channel conditions and QoS requirements. This dynamic scheduling allows the system to adapt to varying propagation environments while maintaining QoS, and the terminal can enter power-saving mode during periods when no transmission is scheduled, thus resolving the contradiction between dynamic allocation and power consumption.
Solution Approach 2:
The patent divides communication into periodic time slots with different characteristics: a first period for omnidirectional transmission, a second period for potential retransmission, and a third period for directional transmission. By structuring communication as periodic actions with predetermined patterns, the terminal can anticipate active periods and enter power-saving modes during inactive periods, satisfying QoS requirements while reducing overall power consumption.
2Use of energy by moving object
If the communication period is set in advance by the access point, then power consumption is reduced, but QoS requirements may not be satisfied due to incomplete signal retransmission
Solution Approach 1:
The patent segments the communication period into multiple distinct periods: a first period for initial omnidirectional transmission, a second period for potential retransmission, and a third period for directional transmission. This segmentation allows the system to maintain predetermined scheduling for power saving while ensuring that each segment serves a specific function to complete signal transmission successfully, even in degraded propagation environments.
Solution Approach 2:
The patent performs preliminary actions by allocating multiple periods in advance: the first period for initial transmission, the second period prepared for retransmission if needed, and the third period for directional transmission. This preliminary allocation ensures that power consumption is reduced through predetermined scheduling while guaranteeing that resources are already prepared to handle signal retransmission requirements, thus resolving the contradiction between power saving and transmission completion.
3Area of stationary object
If omnidirectional radio waves are used for signal transmission, then coverage is improved, but power consumption increases compared to directional transmission
Solution Approach 1:
The patent applies different transmission qualities to different time periods: omnidirectional transmission with wider coverage in the first period, and directional transmission with focused energy in the third period. By assigning different transmission characteristics to different local contexts (time periods and channel conditions), the system optimizes the balance between coverage area and power consumption, using omnidirectional only when necessary and directional when sufficient coverage is achieved.

AI summary
A communication device includes a receiver, a transmitter and an interruption module. The receiver receives an allocation signal indicating a first period usable by the communication device and a second period usable by a plurality of communication devices including the communication device. The transmitter transmits a transmission signal in the first period. If the transmission of the transmission signal is completed within the first period, the interruption module interrupts at least a part of power supply to the receiver in the second period. If the transmission of the transmission signal is not completed within the first period and directivity of radio waves used by a second communication device includes a direction of the communication device in a communication period allocated before the second period, the transmitter transmits the transmission signal in the second period.
