Scheduling Request Enhancements For 5G Networks - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240373461 titled 'Scheduling Request Enhancements For 5G Networks

The patent application describes an apparatus for user equipment (UE) that can communicate data in a new radio-unlicensed (NR-U) spectrum by decoding RRC signaling from a base station.

The processing circuitry is coupled to memory and decodes RRC signaling, which includes configuration information for setting up a Listen-Before-Talk (LBT) timer and a Scheduling Request (SR) prohibit timer.
The UE performs an LBT procedure while the LBT timer is activated to detect an unoccupied transmission resource within the NR-U spectrum.
Based on the detection, the UE encodes an SR for transmission to the base station, activating the SR prohibit timer.
Upon receiving an uplink grant from the base station in response to the SR, the UE decodes the grant while the SR prohibit timer is still active.
The UE then encodes a Buffer Status Report (BSR) for transmission to the base station based on the uplink grant.

Potential Applications: - This technology can be used in wireless communication devices to efficiently utilize the NR-U spectrum. - It can enhance the performance of IoT devices operating in unlicensed spectrum bands.

Problems Solved: - Efficient utilization of the NR-U spectrum. - Improved communication reliability in unlicensed spectrum bands.

Benefits: - Enhanced data communication capabilities. - Increased spectrum efficiency. - Improved overall performance of wireless devices.

Commercial Applications: Title: Enhanced Spectrum Utilization Technology for Wireless Communication Devices This technology can be applied in IoT devices, smart home systems, and industrial automation for more reliable and efficient data transmission in unlicensed spectrum bands.

Questions about the Technology: 1. How does the decoding of RRC signaling from the base station help in configuring the UE for communication in the NR-U spectrum? - By decoding the RRC signaling, the UE can extract configuration information to set up timers and perform procedures necessary for communication in the new spectrum.

2. What is the significance of the Listen-Before-Talk (LBT) procedure in the context of the NR-U spectrum communication? - The LBT procedure ensures that the UE detects an unoccupied transmission resource before initiating transmission, reducing the chances of interference with other devices.

Original Abstract Submitted

an apparatus of user equipment (ue) includes processing circuitry coupled to memory, where to configure the ue for communication of data in a new radio-unlicensed (nr-u) spectrum, the processing circuitry is to decode rrc signaling from a base station. the rrc signaling includes configuration information to configure a listen-before-talk (lbt) timer and a scheduling request (sr) prohibit timer. an lbt procedure is performed while the lbt timer is activated. an sr is encoded for transmission to the base station, based on detecting an unoccupied transmission resource within the nr-u spectrum during the lbt procedure. the sr transmission activates the sr prohibit timer. an uplink grant from the base station is decoded in response to the sr, the uplink grant received while the sr prohibit timer is activated. a buffer status report (bsr) is encoded for transmission to the base station based on the uplink grant.
