Methods for SL SR/BSR Handling - A simplified explanation of the abstract
This abstract first appeared for US patent application 18401969 titled 'Methods for SL SR/BSR Handling
Simplified Explanation
The patent application describes methods for a wireless device to communicate with a network and other devices using both an uplink and a sidelink. The device triggers scheduling requests to obtain grants for transmitting buffer status reports indicating available data for transmission.
- The wireless device triggers a scheduling request to obtain a grant for transmitting a buffer status report for data available to be sent via the sidelink.
- Before transmitting the sidelink scheduling request, the device transmits an uplink scheduling request to obtain a grant for transmitting a buffer status report indicating data available to be sent via the uplink.
- The device selectively transmits the sidelink buffer status report using the uplink grant and cancels the sidelink scheduling request transmission after transmitting the buffer status report.
Potential Applications
This technology could be applied in various scenarios where direct device-to-device communication is required, such as in emergency situations, public safety communications, and industrial IoT applications.
Problems Solved
This technology solves the problem of efficiently managing and transmitting data between wireless devices using both uplink and sidelink channels without causing interference or delays in communication.
Benefits
The benefits of this technology include improved reliability and efficiency in device-to-device communication, reduced latency in transmitting critical data, and optimized use of available network resources.
Potential Commercial Applications
Potential commercial applications of this technology include public safety communication systems, smart city infrastructure, industrial automation, and vehicle-to-vehicle communication systems.
Possible Prior Art
One possible prior art for this technology could be existing methods for managing uplink and sidelink communications in wireless networks, such as LTE-Direct or WiFi Direct protocols.
Unanswered Questions
How does this technology impact battery life of the wireless device?
The patent application does not provide information on how this technology may impact the battery life of the wireless device. It would be important to understand if the additional signaling and data transmission required for managing uplink and sidelink communications have any significant impact on the device's power consumption.
What are the potential security implications of using both uplink and sidelink channels for communication?
The patent application does not address the potential security implications of using both uplink and sidelink channels for communication. It would be crucial to consider how data privacy and security measures are implemented to protect the transmitted information from unauthorized access or interception.
Original Abstract Submitted
Embodiments include methods performed by a wireless device configured to communicate via an uplink (UL) to a network and via a sidelink (SL) to one or more other wireless devices. Such methods include, based on availability of data to be sent via the SL, triggering a SL Scheduling Request (SR) to obtain a first UL grant to facilitate transmission of a Sidelink (SL) Buffer Status Report (BSR) indicating the data available to be sent via the SL. Such methods include, prior to transmitting the SL SR to obtain the first UL grant, transmitting an UL SR to obtain a second UL grant to facilitate transmission of an UL BSR indicating data available to be sent via the UL. Such methods include selectively transmitting the SL BSR using the second UL grant and cancelling the SL SR transmission in response to transmitting the SL BSR using the second UL grant.
