Abstract: The embodiments of the present disclosure provide a method for processing an LBT parameter, a method for adjusting a contention window and associated apparatuses. The method for processing an LBT parameter includes: generating, by a first station, an LBT parameter comprising a parameter used by the first station to perform LBT for unlicensed carriers and/or indicating a parameter used by a second station receiving the LBT parameter to perform LBT for the unlicensed carriers; and transmitting, by the first station, the LBT parameter. With the embodiments of the present disclosure, the problem associated with interference due to unlicensed carrier contention by neighboring stations can be solved, such that the interference between the neighboring stations due to unlicensed carrier contention by the neighboring stations can be avoided.

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: Methods, systems, and devices are disclosed for implementing a transmission and feedback mechanism to enable the collaboration of different service types and efficient reporting of the transmission status. In one aspect, the disclosed technology can be implemented to provide a wireless communication method that includes receiving a message that includes a predetermined number of code block groups for a transmission; and dividing a plurality of data blocks in the transmission into a first part and a second part. The first part comprises a first number of code block groups and the second part comprises a second number of code block groups. The second number of code block groups is determined based on the predetermined number of code block groups in the control message.

Abstract: A method and apparatus are described for adaptive interference discovery of a licensed shared access (LSA) system. The method includes: an LSA controller selects a measurement node according to interference protection information of an LSA licensed system; the LSA controller sends a measurement configuration message to the measurement node; and the LSA controller receives a measurement response message returned by the measurement node and determines whether to perform LSA spectrum resource reconfiguration according to the measurement response message.
