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: A method and apparatus for allocating resources to carrier response information feedback are disclosed. Wherein, when Transmit Power Control (TPC) command in Downlink Control Information (DCI) for each secondary component carrier in carrier aggregation is different, Physical Uplink Control Channel (PUCCH) resources allocated to the response information feedback of the secondary component carriers are high-layer configuration PUCCH resources designated by TPC command in the DCI which triggers data services in the secondary component carriers. The present solution can not only effectively feedback response information, but also can effectively suppress occurrence of unnecessary downlink retransmission.
