BANDWIDTH PARTS DEACTIVATION AND DISCONTINUOUS RECEPTION FOR COMMUNICATION BETWEEN WIRELESS DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17995376 titled 'BANDWIDTH PARTS DEACTIVATION AND DISCONTINUOUS RECEPTION FOR COMMUNICATION BETWEEN WIRELESS DEVICES
Simplified Explanation
The patent application describes a method and apparatus for managing communication between wireless devices by deactivating bandwidth parts (BWPs) and implementing discontinuous reception (DRX). Here are the key points:
- The method involves a first wireless device transmitting a media access control (MAC) protocol data unit (PDU) to a second wireless device in a wireless communication system.
- After a specific repetition of the MAC PDU transmission, the first wireless device starts a discontinuous hybrid automatic repeat request (HARQ) round trip time (RTT) timer for a HARQ process ID.
- The first wireless device also starts a DRX retransmission timer based on the expiration of the DRX HARQ RTT timer and the number of transmissions of the MAC PDU not reaching the maximum limit.
- During the active time when the DRX retransmission timer is running, the first wireless device monitors a physical downlink control channel (PDCCH) that carries a sidelink retransmission grant.
Potential applications of this technology:
- Wireless communication systems: The method and apparatus can be applied in various wireless communication systems to improve the efficiency and reliability of communication between devices.
- Internet of Things (IoT): The technology can be beneficial for IoT devices that require low power consumption and intermittent communication.
Problems solved by this technology:
- Efficient resource utilization: By deactivating bandwidth parts and implementing discontinuous reception, the method helps optimize the use of available resources in wireless communication systems.
- Reliable communication: The use of hybrid automatic repeat request (HARQ) and retransmission timers ensures reliable data transmission between wireless devices.
Benefits of this technology:
- Improved power efficiency: The implementation of discontinuous reception (DRX) helps reduce power consumption in wireless devices by allowing them to enter sleep mode during inactive periods.
- Enhanced reliability: The use of HARQ and retransmission timers improves the reliability of data transmission by enabling retransmission of lost or corrupted packets.
- Optimal resource allocation: Deactivating bandwidth parts when not in use allows for efficient allocation of resources to other devices or applications.
Original Abstract Submitted
A method and apparatus for bandwidth parts (BWPs) deactivation and discontinuous reception (DRX) for communication between wireless devices is provided. A first wireless device operating in a wireless communication system performs transmission of a media access control (MAC) protocol data unit (PDU) to a second wireless device, and starts a discontinuous (DRX) hybrid automatic repeat request (HARQ) round trip time (RTT) timer for a HARQ process ID after end of a specific repetition of the transmission of the MAC PDU. The first wireless device starts a DRX retransmission timer based on 1) the DRX HARQ RTT timer being expired, and 2) a number of transmissions of the MAC PDU not reaching a maximum number of transmissions, and monitors a physical downlink control channel (PDCCH) carrying a sidelink retransmission grant during an active time including a time interval for which the DRX retransmission timer is running.
