SYSTEMS AND METHODS FOR CHANGING LBT FOR UNLICENSED NETWORKS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18021192 Titled 'SYSTEMS AND METHODS FOR CHANGING LBT FOR UNLICENSED NETWORKS'
Simplified Explanation
This abstract describes systems and methods for changing the Listen Before Talk (LBT) mechanism in unlicensed networks. The method involves a wireless device receiving signaling from a base station indicating whether to use LBT for transmissions. Based on this signaling, the device determines whether or not to use LBT and transmits accordingly. This approach aims to reduce collisions and interferences in network performance by adaptively using LBT. The method defines two simple modes for LBT operation: LBT mode and No LBT mode, providing a low complexity solution with minimal signaling overhead and specification impact.
Original Abstract Submitted
Systems and methods for changing Listen Before Talk (LBT) for unlicensed networks are provided. In some embodiments, a method performed by a wireless device includes: receiving signaling from a base station that indicates when the wireless device uses LBT for transmissions; determining, based on the received signaling, whether or not to use LBT for transmissions; and transmitting based on the determination whether or not to use LBT for transmissions. Some embodiments provide a low complexity (in term of signaling overhead and specification impact) approach of adaptively using LBT mechanism by defining two simple modes for LBT operation (LBT and No LBT modes). Some embodiments reduce the probability of simultaneous transmissions that cause collisions, by using LBT mode, in environments and circumstances where network performance suffers from collision and/or interferences.
