EXPIRATION PERIODS FOR LOW LATENCY COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18600425 titled 'EXPIRATION PERIODS FOR LOW LATENCY COMMUNICATIONS

Simplified Explanation: The patent application describes methods, systems, and devices for wireless communications, specifically focusing on transmitting an expiration indication to a receiving device as part of a scheduling message for a transport block. This expiration indication provides information about the expiration time of the transport block, allowing the receiving device to take appropriate actions if the block expires before successful reception.

• The transmitting device sends an expiration indication to the receiving device in a scheduling message for a transport block.
• The expiration indication conveys the expiration time of the transport block.
• If the transport block expires before successful reception, the receiving device may refrain from sending a retransmission grant or empty a HARQ buffer associated with the block.
• If the transmitting device does not receive an indication of successful reception before the expiration period, it assumes the block has expired.

Potential Applications: 1. Mobile telecommunications networks 2. Internet of Things (IoT) devices 3. Satellite communications systems

Problems Solved: 1. Efficient management of transport block expiration in wireless communications. 2. Avoiding unnecessary retransmissions of expired blocks. 3. Optimizing the use of HARQ buffers.

Benefits: 1. Improved reliability of wireless communication systems. 2. Enhanced efficiency in data transmission. 3. Reduction of network congestion.

Commercial Applications: The technology can be applied in 5G networks, IoT devices, satellite communication systems, and other wireless communication technologies to enhance data transmission efficiency and reliability.

Prior Art: Readers can explore prior patents related to wireless communication protocols, HARQ mechanisms, and transport block management to gain a deeper understanding of the existing technology landscape.

Frequently Updated Research: Researchers are continuously exploring advancements in wireless communication protocols, HARQ mechanisms, and transport block management to improve the performance of wireless networks.

Questions about Wireless Communications: 1. How does the expiration indication improve the efficiency of wireless communication systems? 2. What are the potential implications of optimizing HARQ buffer management in wireless networks?

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARQ) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.
