Abstract: A timing advance sending method and a timing advance sending apparatus that improves the efficiency of a communication network. The efficiency of the communication network is improved by sending relative timing advance to a base station, where the relative timing advance is determined based on a relationship between a distance between the terminal and a non-terrestrial network device and a distance from the network device to an earth reference point. The determined relative timing advance is relatively small in comparison with a propagation delay corresponding to all communication links between the terminal and the base station, so that a number of bits that requires to be occupied is relatively small and thus a number of bits that requires to be occupied by the terminal to report the relative timing advance is relatively small, which helps to save communication resources.

The method further includes determining a type of data transmitted in the HARQ process indicated by the first DCI based on a type of the first DCI and contents included in the first DCI, in response to an identifier of a physical downlink control channel (PDCCH) corresponding to the first DCI as a broadcast or multicast scheduling identifier.

Abstract: A method and apparatus are disclosed for processing sidelink continuous listen-before-talk (LBT) failures in user equipment operating in a wireless communication system. The method includes determining that a currently used resource—such as a resource pool, resource block (RB) set, or activated bandwidth part (BWP)—triggers a sidelink continuous LBT failure, and triggering resource reselection accordingly. In carrier aggregation scenarios, the user equipment selects an alternative resource from the same or another carrier, with preference given to resources on the current carrier unless a threshold number of failures occurs. In non-carrier aggregation scenarios, the resource reselection is limited to the current carrier. If a threshold number of failures is detected across configured resources, the user equipment may trigger a sidelink radio link failure (SL RLF) and notify a higher layer to release all associated sidelink radio resource control (SL-RRC) connections.
