1. A method for information reporting, being applicable to a terminal, the terminal being configured with one or more uplink (UL) bandwidth parts (BWP), at least one active UL BWP existing in the one or more UL BWPs, and the method comprising:
detecting, by the terminal, occurrence of a listen before talk (LBT) failure in the active UL BWP; and
reporting, by the terminal, indication information to a network device when the terminal detects that the LBT failure occurs in any active UL BWP, the indication information being used for indicating the LBT failure, wherein
a cell configured for the terminal comprises a master cell group (MCG) and a secondary cell group (SCG), the MCG comprises a PCell and an SCell, the SCG comprises a primary secondary cell (PScell) and a secondary cell (SCell), and reporting, by the terminal, the indication information to the network device comprises:
initiating, by the terminal, an RRC reestablishment procedure and transmitting the indication information to the network device through the RRC reestablishment procedure, when a first UL BWP where the LBT failure occurs is a UL BWP configured for the PCell of the MCG; or
initiating, by the terminal, a failure information procedure and transmitting the indication information to the network device through the failure information procedure, when the first UL BWP where the LBT failure occurs is a UL BWP configured for the PScell or the SCell, and
wherein the indication information further comprises:
identifier information of the cell where the first UL BWP is configured, wherein the LBT failure occurs in the first UL BWP; and
a UL transmission type, an LBT category, and/or a priority of a channel accessed by the terminal corresponding to the LBT failure.
