首先扫描所有可用的信道,并锁定发送空闲信号的信道进行通话, 这种机制也称为 LBT(Listen Before Talk)...
Aspects for uplink (UL) communications related to listen before talk (LBT) operations in wireless networks introduce techniques and network devices configured to enable these communications by considering contention window size adaptation and related conditions. In some aspects, a user equipment (UE) ...

Wireless communications systems and methods related to performing random backoff over multiple spatial dimensions in spatial listen-before-talk (LBT) procedures are provided. A first wireless communication device determines a first backoff counter for contending for a transmission opportunity (TXOP) in a...
Further, 3GPP TR 36.889 V13.0.0 recommends that the UE performs a listen-before-talk (LBT) procedure before performing a UL radio transmission, which means that the UL transmission would depend on success of the LBT procedure performed by the UE. For example, if the LBT procedure reveals tha...
Based on the channel sensing metrics, the apparatus then determines a Listen Before Talk (LBT) mode and/or a LBT sensing time. The UE then performs a LBT process using the LBT mode and the LBT sensing time. If the UE determines that the radio channel is not occupied, the UE transmits...
LoRa networks use listen-before-talk (LBT) in unslotted ALOHA to accommodate numerous sensors, often across areas exceeding 10 km. Due to potential hidden nodes, devices may incorrectly detect idle channels. This letter investigates the effectiveness of LBT in LoRa, focusing on the hidden node pr...
Disclosed in some examples are systems, machine-readable media, methods, and cellular wireless devices which implement a Listen-Before-Talk (LBT) access scheme for a device operating according to a cellular wireless protocol in an unlicensed channel. A cellular wireless device may utilize the cellula...
based on the second uplink time interval starting later than the first uplink time interval by a threshold timing difference and based on a listen before talk (LBT) procedure indicating a clear channel for the unlicensed cell, cause the transmission in the second uplink time interval via the ...
