    Abstract: The present disclosure provides a method and an apparatus for determining a Listen Before Talk (LBT) mode, as well as a method for LBT mode switching. The method includes: determining (100) an LBT mechanism and/or an LBT mechanism parameter set based on related indication information and/or priority information and/or measurement information; and performing (101), by a transmitting device, contention-based channel access based on the determined LBT mechanism and/or LBT mechanism parameter set. With the present disclosure, an LBT mode can be determined. With the selection of the LBT mode, it is possible to avoid waste of channel resources and indication information due to an improper LBT mode, thereby improving an efficiency of contention-based channel access.

    Abstract: Provided are an uplink transmission and communication methods and devices, a base station, a terminal and a storage medium. In the provided uplink transmission method, a terminal determines at least one autonomous transmission parameter for uplink transmission, sends the at least one autonomous transmission parameter to a base station, and then send uplink data to the base station according to the at least one autonomous transmission parameter. After receiving the at least one autonomous transmission parameter sent by the terminal, the base station detects and receives, according to the at least one autonomous transmission parameter, data sent by the terminal. In this manner, the terminal can flexibly transmit data according to currently available transmission resources without having to passively and rigidly wait until the transmission resources satisfy the scheduling requirements of the base station before performing transmission.

    Abstract: Embodiments provide a contention-based access method and device, which include that: a transmission node acquires predefined information; and the transmission node performs contention-based access according to the predefined information, wherein the predefined information includes at least one of: a frame structure, a data transmission subframe location, a data type, dedicated indication signaling, a frame scheduling manner and data transmission. Listen Before Talk (LBT) different from Downlink (DL) is adopted, and a flow is simplified when Uplink (UL) LBT is executed, so that the problems of poor UL performance and low spectrum efficiency caused by adoption of DL LBT for UL in the related solution may be solved.

    Abstract: Disclosed are devices, systems and methods for channel access procedures that include a listen-before-talk (LBT) rule for preventing a mismatch between a sensing beam and a transmission beam. In some implementations, a data communication method includes detecting an idle channel by performing, by a communication node, an energy detection operation based on at least one of a transmission beam or a reception beam, and transmitting, upon detection of the idle channel in at least one of the transmission beam or the reception beam, messages through the transmission beam corresponding to the idle channel.
